Abstract
The objective of this study was to determine the contents of heavy metals in some common spices commercially available in the North Shewa Zone, Oromia region, Ethiopia. Korarima seed (Aframomum corrorima), ginger rhizome (Zingiber officinale), red pepper fruit (Capsicum annum), and turmeric rhizome (Curcuma longa) samples were randomly collected from the Fiche open market. These spice samples were digested using a mixture of 3 mL of HNO3 (69-72%) and 1 mL of HClO4 (70%), where organic components are assumed to decompose into gaseous forms while other heavy metal elements are left in the solution. The contents of heavy metals (Fe, Zn, Cu, Cr, Mn, Ni, Cd, and Pb) in the spices were determined by inductively coupled plasma‒optical emission spectrometry (ICP‒OES). The results obtained showed that the concentrations of heavy metal in the korarima, red pepper, ginger, and turmeric samples in milligrammes per kilogramme of dry weight were in the range of Fe (38.7-98.9), Mn (10.5-257), Zn (7.30-29.2), Cu (1.70-6.50), Cr (5.40-9.70), Cd (1.50-2.90), Pb (14.5-28.4), and Ni (3.90-6.70). The heavy metal contents in korarima, red pepper, ginger, and turmeric samples were compared with the maximum values given by the World Health Organization (WHO). Accordingly, the Fe, Zn, Cu, Cr, Mn, and Ni values in the spice samples were found to be lower than the maximum limit of the WHO, while the levels of Pb and Cd in four spice samples and Mn (only in ginger) were higher than the WHO permissible limit. This study shows that the consumption of korarima, red pepper, ginger, and turmeric may pose a serious health threat to consumers due to the high content of lead, cadmium, and manganese (only in ginger) in spices. Therefore, it is suggested that further study be conducted on spice samples based on the origin of cultivation to determine which hotspot is responsible for high levels of contamination of lead, cadmium, and manganese to protect consumers.

Abstract
In this study, risk estimation based on sampling and subsampling uncertainty was performed for pesticide analysis in homogeneous spice products such as paprika. The results of the subsampling were also used to estimate the minimum weight necessary in subsampling to minimize overall uncertainty. The results show that subsampling has more uncertainty than sampling in the product due to high homogeneity in the manufacturer's batch. On the other hand, results using the Monte Carlo (MC) simulation on the size of the subsample indicate that uncertainty is lower for weights between 20 and 30 g and increases for sample sizes of 100 g. A sample size of 30 g was used for saffron, and the values simulated with the MC method were confirmed.

Abstract
INTRODUCTION Synthetic cannabinoids (i.e. Spice) are a major public health problem in UK prisons, however, research in this area is limited. Here we aimed to draw comparisons between people with and without experience of using synthetic cannabinoids in prison, to characterise the features of, and motivations for use within this setting and evaluate support for different treatment interventions. METHOD Questionnaires were administered to 122 people in a category-B prison for adult males in England between July 2022 and March 2023. Participants were asked questions related to their sociodemographic and custodial characteristics, use of synthetic cannabinoids (and other drugs) inside and outside of prison and psychological distress was measured via the Brief Symptom Inventory (BSI-18). Those that had ever used synthetic cannabinoids in prison completed additional questions related to features of use, motivations for use and support for various interventions. RESULTS In total 46.7 % (n = 57) of participants reported use of synthetic cannabinoids in prison and this group experienced significantly greater levels of psychological distress compared to those reporting no use (mean (± standard deviation) BSI-18 scores = 23.7 (±16.7) vs 12.8 (±13.6), p < 0.001). Participants mostly reported using paper-based preparations (77.4 %) and use via e-cigarettes (75.9 %). The most strongly endorsed motivations for use included to alleviate boredom (91.1 % strongly agree/agree), to make the sentence pass faster (89.3 % strongly agree/agree) and to cope with stress (80.4 % strongly agree/agree). The interventions that received most support were strategies to better manage time and medication to manage withdrawal. CONCLUSIONS The use of synthetic cannabinoids in UK prisons typically involves the use of paper-based preparations via e-cigarettes, and use is associated with greater levels of psychological distress. Motivations for use were mostly pragmatic (e.g. to alleviate boredom or cope with stress) and interventions should prioritise increasing the time individuals spend out of cells and in meaningful activity.

Abstract
Bacillus cereus is a pathogenic bacterium commonly found in nature and can produce toxins that cause food poisoning. This study aimed to detect the prevalence of B. cereus group bacteria in 50 unpackaged and 20 packaged spice samples frequently used as flavoring in Turkish cuisine, as well as investigate the presence of toxin genes and antibiotic resistance in the isolates. A total of 48 B. cereus group bacteria were isolated from 27 of 70 (38.57%) spice samples. The prevalence of B. cereus group bacteria in packaged (25%, 5/20) and unpackaged (44%, 22/50) spice samples did not differ significantly (P ˃ 0.05). All B. cereus group isolates were identified as B. cereus sensu stricto (B. cereus) using molecular methods. The hemolytic activity tests revealed that the most strains (44/48, 91.67%) are β-hemolytic. The distributions of toxin genes in isolates were investigated by PCR. It was determined that all isolates were identified to have 2-8 toxin genes, except B. cereus SBC3. The three most common toxin genes were found to be nheA (47/48, 97.92%), nheB (46/48, 95.83%), and entFM (46/48, 95.83%). All B. cereus isolates were susceptible to linezolid and vancomycin, while 35.42% (17/48) showed resistance to erythromycin. Multi-drug resistance (MDR) was detected in 8.3% (4/48) of B. cereus isolates, while 33.33% of the isolates showed multiple antibiotic resistance (MAR) index values higher than 0.2. The findings indicate that B. cereus may pose a health risk in packaged and unpackaged spices if present in high quantities. Therefore, the presence of B. cereus strains in both packaged and unpackaged spices should be monitored regarding consumer health and product safety.

Abstract
Improved biosynthesis of commercially and pharmacologically relevant phytometabolites through genetic and metabolic engineering is a lucrative strategy for crop improvement. However, identifying appropriate biosynthetic pathways pertaining to specific bioactivities has been challenging since the major metabolic pathways remain closely interconnected. Here we propose a reverse association strategy in which, based on the phytochemical profile, putative target metabolic pathways could be identified for increased production of phytochemicals. Dried seed fruits of Coriandrum sativum, Trachyspermum ammi, Cuminum cyminum, and Foeniculum vulgare (family Apiaceae) were subjected to untargeted gas chromatography-mass spectrometry-based phytochemical profiling followed by evaluation of the overall antioxidant profile using multiple antioxidant assays. Using bioinformatics approaches, specific phytochemical classes and the enrichment of their respective biosynthetic pathways were identified. Collectively, the data suggest enrichment of isoprenoids and fatty acids biosynthetic pathways. The close association of metabolic pathways with antioxidant capacities indicated a need for enrichment of specific yet closely-related metabolic pathways to achieve an improved quality of spices for better antioxidant effects.

Abstract
(1) Background: Synthetic cannabinoids (SCs) are emerging drugs of abuse sold as 'K2', 'K9' or 'Spice'. Evidence shows that using SCs products leads to greater health risks than cannabis. They have been associated with greater toxicity and higher addiction potential unrelated to the primary psychoactive component of marijuana, Δ9-tetrahydrocannabinol (Δ9-THC). Moreover, early cases of intoxication and death related to SCs highlight the inherent danger that may accompany the use of these substances. However, there is limited knowledge of the toxicology of Spice ingredients. This systematic review intends to analyze the toxicity of SCs compounds in Spice/K2 drugs. (2) Methods: Studies analyzing synthetic cannabinoid toxicity and dependence were included in the present review. We searched the PubMed database of the US National Library of Medicine, Google Scholar, CompTox Chemicals, and Web of Science up to May 2022. (3) Results: Sixty-four articles reporting the effects of synthetic cannabinoids in humans were included in our review. Ten original papers and fifty-four case studies were also included. Fourteen studies reported death associated with synthetic cannabinoid use, with AB-CHMINACA and MDMB-CHMICA being the main reported SCs. Tachycardia and seizures were the most common toxicity symptoms. The prevalence of neuropsychiatric symptoms was higher in third-generation SCs. (4) Conclusion: SCs may exhibit higher toxicity than THC and longer-lasting effects. Their use may be harmful, especially in people with epilepsy and schizophrenia, because of the increased risk of the precipitation of psychiatric and neurologic disorders. Compared to other drugs, SCs have a higher potential to trigger a convulsive crisis, a decline in consciousness, and hemodynamic changes. Therefore, it is crucial to clarify their potential harms and increase the availability of toxicology data in both clinical and research settings.

Abstract
Red soil of Hormuz Island has become a tourist attraction and it has various industrial applications. Despite the uncertainty of the health effects, geophagy is one of the common ways of people exposure to the red soil. This soil is widely used as a local spice and plays an important role in the food culture of the region. This study aimed to quantify the level of selected heavy metals (Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, V, Zn, Ag, Cd, Hg) in the red soil. The content of the metals was measured by ICP-MS (inductively coupled plasma-mass spectrometry). Moreover, risk assessment via heavy metals was carried out by computing the values of Total Hazard Quotient (THQ) and Hazard Index (HI). The results of this study showed that Fe was the most abundant metal among all analyzed metals and the health risk associated with Fe was individually higher than other measured metals. Altough the value for total heavy metals toxicity assessment was found lower than 1 , due to increasing use of red soil as a spice among Hormuz island natives, establishing special industries in order to reducing the amount of heavy metals content in red soil is recommended.

Abstract
Boar taint masking strategies were developed using hydrocolloids and spices to produce edible gels and films. Carrageenan (G1) and agar-agar (G2) were used for the gels and gelatin (F1) and alginate+maltodextrin (F2) for the films. The strategies were applied to both castrated (control) and entire male pork with high levels of androstenone and skatole. The samples were evaluated sensorially by a trained tasting panel through quantitative descriptive analysis (QDA). Lower hardness and chewiness of entire male pork, with high levels of boar taint compounds object of study, were found with the carrageenan gel, due to the better carrageenan gel adherence to the loin. The films showed that the gelatin strategy tended to have a certain "sweet" taste, and a higher overall masking than the alginate+maltodextrin film. In conclusion, a trained tasting panel found that gelatin film masked boar taint the most, followed by the alginate+maltodextrin film and the carrageenan-based gel.

Abstract
Synthetic cannabinoids (SCs) are a chemically diverse group of new psychoactive substances (NPSs) that target the endocannabinoid system, triggering a plethora of actions (e.g., elevated mood sensation, relaxation, appetite stimulation) that resemble, but are more intense than, those induced by cannabis. Although some of these effects have been explored for therapeutic applications, anticipated stronger psychoactive effects than cannabis and reduced risk perception have increased the recreational use of SCs, which have dominated the NPS market in the United States and Europe over the past decade. However, rising SC-related intoxications and deaths represent a major public health concern and embody a major challenge for policy makers. Here, we review the pharmacology and toxicology of SCs. A thorough characterization of SCs' pharmacodynamics and toxicodynamics is important to better understand the main mechanisms underlying acute and chronic effects of SCs, interpret the clinical/pathological findings related to SC use, and improve SC risk awareness.

Abstract
Synthetic cannabinoids cannot be detected on a standard urine drug screen (UDS), making them a convenient drug of abuse. We report the first case of ST elevation myocardial infarction (STEMI) in a young patient due to coronary artery thrombosis secondary to synthetic cannabinoid use and concurrent COVID-19 infection. A 38-year-old previously healthy male developed severe chest pain and was found to have anterior STEMI and COVID-19 infection. Coronary angiography showed acute thrombotic occlusion of the mid-left anterior descending artery that was managed with thrombectomy and stent placement. He only required supportive care for COVID-19. A comprehensive literature search revealed 34 additional cases of STEMI with synthetic cannabinoid use; majority were males (97%) with mean age of 29 years. 29 patients (85.3%) underwent coronary angiography and majority had left anterior descending artery (LAD) involvement (55%), with 13 (44.8%) undergoing stent placement. We highlight STEMI as a potentially lethal complication of synthetic cannabinoids; prompt angiography may be lifesaving.

Abstract
BACKGROUND Though synthetic cannabinoid receptor agonists (SCRAs) were controlled after being introduced as a 'legal high,' SCRAs likely remain appealing to individuals subject to routine drug screens as not all testing programs consistently include SCRAs. Military populations have been linked to SCRAs due to the unconfirmed supposition that testing protocols led many to substitute SCRAs for cannabis. This study aimed to explore SCRA use prevalence, correlates, and use motivations among veterans, with a particular focus on whether United States military personnel substituted SCRAs for cannabis to subvert testing protocols. METHODS All veterans appearing in one of eight civilian criminal courts in three U.S. states were invited to answer questionnaire items related to military service, court functionality, and substance use. Of the 579 veterans eligible, 54.9% chose to participate, yielding a cross-sectional sample of 318 veterans charged with a criminal offense by civilian authorities. RESULTS Sixty-five (21.3%) justice-involved veterans reported lifetime SCRA use. Use while within the military was reported by 15.0% of veterans enlisting after 2008. Only eight (12.3%) reported SCRAs were used as a substitute for cannabis. Boredom (36.9%), experimentation (27.7%), and social aspects of SCRA use (32.3%) were more commonly reported motives. Logistic regression models indicated that use of cannabis (aPR=2.06, p<.05), hallucinogens (aPR=2.50, p<.01), and SCRAs (aPR=2.49, p<.05) while in the military were risk factors for SCRA use after leaving the military, whereas older age at time of military exist was a protective factor (aPR=.87, p<.01) CONCLUSIONS: Drug testing programs within the military do not appear to have the unintended consequence of routing individuals to more risky drugs; however, SCRAs appear to have been an underappreciated problem within the military. Further, use extends beyond the military with many only initiating use after discharge, suggesting SCRA use may jeopardize the health of veterans post-service.

Abstract
A 44-year-old male with no known past medical history but a known history of daily synthetic marijuana use presented to the emergency department after two witnessed seizures. The patient was admitted to the neurology service, where he was worked up with an MRI with epilepsy protocol and an EEG. During admission, the patient was admitted to daily synthetic marijuana use. He did note that he had started to decrease the amount of mojo he used daily in an attempt to stop. His last use was at 9 am the day of his admission. He was trying to decrease his use; his girlfriend of difficulty word-finding noted periods. Synthetic marijuana (SM) or "mojo" use has been increasing in the past decade for two reasons; It is considered an herbal product and has been legal. A withdrawal syndrome of SM use has been characterized chiefly as tachycardia, irritation, anxiety, and mood swings. These withdrawal symptoms are usually seen with chronic use. Some early results in the literature also show that SM use can lead to functional and structural neuronal changes. This manuscript discusses a case of a first on-set seizure as a possible withdrawal symptom in chronic SM use.

Abstract
BACKGROUND Synthetic cannabinoids (SCs) are the largest class of novel psychoactive substances (NPS) and are associated with an increased risk of overdosing and adverse events such as psychosis. JWH-018 is one of the earliest SCs and still widely available in large parts of the world. Controlled studies to assess the safety and behavioural profiles of SCs are extremely scarce. AIM The current study was designed to assess the psychotomimetic effects of a moderate dose of JWH-018. METHODS Twenty-four healthy participants (10 males, 14 females) entered a placebo-controlled, double blind, within-subjects trial and inhaled vapour of placebo or 75μg/kg bodyweight JWH-018. To ascertain a minimum level of intoxication, a booster dose of JWH-018 was administered on an as-needed basis. The average dose of JWH-018 administered was 5.52 mg. Subjective high, dissociative states (CADSS), psychedelic symptoms (Bowdle), mood (POMS) and cannabis reinforcement (SCRQ) were assessed within a 4.5-h time window after drug administration. RESULTS JWH-018 caused psychedelic effects, such as altered internal and external perception, and dissociative effects, such as amnesia, derealisation and depersonalisation and induced feelings of confusion. CONCLUSION Overall, these findings suggest that a moderate dose of JWH-018 induces pronounced psychotomimetic symptoms in healthy participants with no history of mental illness, which confirms that SCs pose a serious risk for public health.

Abstract
Synthetic cannabinoid receptor agonists (SCRAs) may be used as an alternative to natural cannabis; however, they may carry a greater risk of problematic use and withdrawal. This study aimed to characterise the withdrawal symptom profile of SCRAs and compare their profile of effect with high-potency herbal cannabis. Global Drug Survey data (2015 and 2016) were used to access a clinically relevant sample of people reporting use of SCRAs >10 times in the past 12-months, a previous SCRA quit attempt, and lifetime use of high-potency herbal cannabis. Participants completed an 11-item SCRA withdrawal symptom checklist and compared SCRAs and high-potency herbal cannabis on their onset and duration of effects, speed of the development of tolerance, severity of withdrawal, and difficulty with dose titration. Participants (n = 284) reported experiencing a mean of 4.4 (95% CI: 4.1, 4.8) withdrawal symptoms after not using SCRAs for >1 day; most frequently reported were sleep issues (59.2%), irritability (55.6%), and low mood (54.2%). Withdrawal symptoms were significantly associated with frequency (>51 vs. 11-50 times per year: IRR = 1.43, 95% CI: 1.16, 1.77, p = 0.005) and quantity (grams per session: IRR = 1.13, 95% CI: 1.05, 1.22, p = 0.001) of SCRA use. Compared to high-potency herbal cannabis, SCRAs were rated as having a faster onset and shorter duration of effects, faster development of tolerance, and more severe withdrawal (p's < 0.001). In conclusion, SCRA withdrawal symptoms are more likely to occur after greater SCRA exposure. The effects of SCRA indicate a more severe withdrawal syndrome and a greater risk of problematic use than natural cannabis.

Abstract
Recreational use of Synthetic Cannabinoids (SCs), one of the largest groups of New Psychoactive Substances (NPS), has increased globally over the past few years. Driving is a structured process requiring the cooperation of several cognitive and psychomotor functions, organized in different levels of complexity. Each of these functions can be affected when Driving Under the Influence (DUI) of SCs. In order to reduce the likelihood of SC-related road accidents, it is essential to understand which areas of psychomotor performance are most affected by these substances, as well as the severity of impairment. For this purpose, a multiple database- literature review of recent experimental studies in humans and animals regarding the psychomotor effects of SCs has been performed. Despite the many limitations connected to experimental studies on humans, results showed a consistency between animal and human data. SCs appear to impair psychomotor performance in humans, affecting different domains related to safe driving even at low doses. Cases of DUI of SC have been repeatedly reported, although the exact prevalence is likely to be underestimated due to current analytical and interpretative issues. For this reason, an accurate physical examination performed by trained and experienced personnel has a primary role in recognizing signs of impairment in case of strong suspicion of SC consumption. The identification of a suspected case should be followed by reliable laboratory examination.

Abstract
The effect of different type and spice percentage on the physicochemical and consumer preferences of sunflower seed investigated. Samples had moderate consumers’ total acceptance. PLS analysis showed the results of consumer preferences and instrumental properties were in agreement with each other.
Roasting is an important process in the industry of nuts and seeds production. The aim of this study was the effect of different spices (red pepper, paprika, hibiscus tea, curry powder, sistani wrench, black plum peel puree, caraway, fennel, vegetables) on the moisture content, texture characterizations and sensory properties of roasted sunflower seed. The roasting process was performed under similar industrial conditions. Sholi (coating agents with spices (4 and 6%)) was prepared and added to the samples during the roasting process. The results showed the sample containing 4% vegetables had the highest hardness and penetration work, while, the sample with 6% hibiscus tea had the highest moisture content and the lowest elasticity. Furthermore, the sample contained 6% and 4% paprika had the highest elasticity and the lowest moisture content, respectively. Sensory properties of roasted sunflower seeds indicated that samples had moderate consumers’ total acceptance, maybe, due to the new color and flavor of samples. The fracture force, hardness, penetration work and apparent modulus of elasticity of roasted sunflower seeds were in the range of 11.94–37.71 N, 28.31–55.83 N, 55.45–98.37 N.s and 12.53–24.06 N/s, respectively. PLS analysis showed the results of total acceptance, sensory hardness and instrumental properties were in agreement with each other. The use of new flavors and colors in this research can increase factory sales and respond to different consumer preferences.

Abstract
The case report centres on analytical findings from a spice sample (mixed with tobacco (as a cigarette) for consumption), and its corresponding plasma sample, smoked by a 31-year-old man who was attended by emergency services following collapse. The man was fully conscious and cooperative during initial medical treatment. Suddenly, he suffered a complete loss of self-control, whereupon the police was notified. The man encountered the police officers when exiting the apartment, at which point he threatened them with clenched fists and reached for a plant bucket in order to strike out in the direction of the officers. At the trial, he described himself as confused and as being completely overwhelmed, having lost self-control, suffered a panic attack and “just wanted to get out the situation”. Furthermore, he stated that he had no recollection of the incident. He feared death due to palpitations, heart pain, dizziness and repetitive anxiety states. Routine systematic as well as extended toxicological analysis of the plasma sample, taken approximately 2 h after the incident, confirmed the use of cannabis and spice. Plasma concentrations of THC, OH-THC and THC-COOH were 8.0 μg/L, 4.0 μg/L and 147 μg/L, respectively. Furthermore, analysis confirmed uptake of 5F-ADB (5F-MDMB-PINACA) via detection of both 5F-ADB and the 5F-ADB N-(5-OH-pentyl) metabolite. The spice sample additionally contained 5F-MDMB-PICA, which was not detected in the plasma sample. A differentiation between a possible co-use and a recent use of cannabis was not possible. In summary, this case once more underlines the health risks of spice use.

Abstract
PURPOSE To study the distribution of 210Po concentrations in various parts of spice plants cultivated by conventional farming in Nilgiris, South India and estimate effective radiation dose received. MATERIALS AND METHODS Parts of plant such as leaf, fruit, seed, flower bud and rhizome of selected spice plants cultivated at various locations in the study area have been collected for estimation of 210Po concentration. Organic materials in known mass of processed samples have been removed by chemical method. 210Po concentration in the digested sample has been electrostatically deposited on pre-polished silver disks at constant temperature. ZnS(Ag) detector-based alpha counting system with minimal detectable value 3.2 mBq has been used for estimation of 210Po activity concentration. RESULTS Leaves of Curcuma longa have registered a high concentration of 45.6 ± 4.5 Bq kg-1 of 210Po and rhizome of Allium sativum has registered a low value of 4.7 ± 0.8 Bq kg-1. Leaves of spice plants have registered higher concentration of 210Po than their fruits, seeds, flower buds or rhizomes. Soil to plant transfer factor of 210Po has been found to vary from 0.13 for rhizome of A. sativum to 2.23 corresponding to leaf of C. longa. Concentration of 210Po estimated in leaves and mean leaf areas of spice plants has been found to have a correlation coefficient of 0.83, which indicates that absorption of 210Po deposited on surface area of leaves is the main source of this isotope in plant parts. CONCLUSIONS Consumption of various parts of spice plant does not pose significant radiological risk as effective dose received by the general public as 210Po has been found to vary from 6.34 to 46.05 µSv y-1, less than the value recommended by ICRP.

Abstract
An untargeted metabolomics approach based on ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) fingerprinting was applied to investigate the metabolic differences of black pepper among three geographical origins (Sri Lanka, Vietnam, and Brazil) and two post-harvest processing (sterilized and non-sterilized spice). Principal component analysis (PCA) was employed to assess the overall clustering of samples, whereas supervised orthogonal partial least squares discriminant analysis (OPLS-DA) was effectively used for discrimination purposes. OPLS-DA models were fully validated (R2Y and Q2 values > 0.5) and the variable importance in projection (VIP) approach was employed to provide valuable data about differential metabolites with high discrimination potential (8 markers were putatively identified). For origin differentiation, three markers were highlighted with VIP values > 1.5 (i.e. reynosin, artabsinolide D, and tatridin B). Fatty acid derivates were the most frequent markers within the metabolites annotated for processing discrimination (e.g. 10,16-dihydroxyhexadecanoic acid and 9-hydroperoxy-10E-octadecenoic acid). Additionally, different combinations of mid-level data fusion of chromatographic-mass spectrometric techniques (UHPLC and gas chromatography coupled to HRMS) and proton nuclear magnetic resonance spectroscopy (1H NMR) were evaluated for the first time for geographical and processing discrimination of black pepper. The NMR-UHPLC-GC mid-level fused model was preferred among the tested fusion approaches since good sample clustering and no misclassification were achieved. Enhanced correct classification rate was achieved by mid-level data fusion compared with the findings obtained for one of the individual techniques (1H NMR fingerprinting) (from 92% to 100% of samples correctly classified). This study opens the path to new metabolomics approaches for black pepper authentication and quality control.

Abstract
A simple microwave-assisted synthesis of nitrogen-doped carbon dots with high oxygen content (O-N-CDs) was carried out with citric acid as a carbon source and 2,4-diamino-6-methyl-1,3,5-triazine as a nitrogen source in triethylene glycol (TEG) media. It was determined by SEM analysis that O-N-CDs consisted of particles of different sizes and shapes. Transmission electron microscopy (TEM), Raman spectroscopy, and X-ray diffraction (XRD) analysis confirmed that O-N-CDs have a graphitic structure. Moreover, they showed a high fluorescence property based on the excitation wavelength. Therefore, a new fluorometric method was developed for the determination of banned food dye Sudan II by using the O-N-CDs. The proposed method was used in the determination of Sudan II in spiked spice samples. The detection limit was 0.6 mg L-1 and the linear range was 0-8 mg L-1.

Abstract
Among food and agricultural products, spices play important roles in the diets of millions of people worldwide. These products may be colonized by fungi genus and subsequently mycotoxin production. Due to the large demand and supply of spice for cooking, preservative effects, or medicine purpose, it is essential that further investigation is designed to examine mycotoxins in spice. In the present study, the possible contamination of spices by aflatoxins (AFTs) and ochratoxin A (OTA) were analyzed. A total of 80 spice samples (curry, sumac, ginger, and saffron) were purchased and cultured on appropriate medium. Simultaneously mycotoxins from spices were extracted with immunoaffinity columns (IAC), and the occurrence of AFTs (B1 + B2 + G1 + G2) and OTA was then determined using high-performance liquid chromatography (HPLC) with a fluorescence detector (FD). The results depicted that 62 (77.5%) and 58 (72.5%) spice samples were contaminated with AFTs and OTA, respectively. Out of the 80 analyzed spices samples, the mean concentration of AFTs and OTA was higher in the curry samples. Among spices that contaminated with mycotoxins, 5 (6.25%) and 2 (10%) of the samples were above the acceptable limit of AFTs (≥ 10 μg/kg) and OTA (≥ 15 μg/kg), respectively. Aspergillus species were the predominant species isolated, followed by Penicillium, and finally Mucor species.Among the examined samples, only few curry samples were contaminated with mycotoxins above acceptable limit. Despite this low level of contamination, this spice is used daily in the cuisine of this region of the world, and consequently, even the small amount of these heat stable toxins for a long time may cause many adverse effects. Hence, it is recommended to monitor the toxicogenous fungi contamination and level of mycotoxins in the spices.

Abstract
Thermal inactivation kinetics of Salmonella in low moisture foods are necessary for developing proper thermal processing parameters for pasteurization. The effect of water activity on thermal inactivation kinetics of Salmonella and Enterococcus faecium NRRL B-2354 in ground black pepper has not been studied previously. Identification of a suitable surrogate assists in conducting in-plant process validations. Ground black pepper was inoculated with a 5-serotype Salmonella cocktail or E. faecium NRRL B-2354, equilibrated to water activities of 0.25, 0.45 or 0.65 in a humidity-controlled chamber, and isothermally treated at different temperatures. The survivor data were used for fitting the log-linear models to obtain the D and z-values of Salmonella and E. faecium in ground black pepper. Modified Bigelow models were developed to evaluate the effects of temperature and water activity on the thermal inactivation kinetics of Salmonella and E. faecium. Water activity and temperature showed significant negative effects on the thermal resistance of Salmonella and E. faecium in ground black pepper. For example, significantly higher D values of Salmonella were observed at water activity of 0.45 (D70°C = 20.5 min and D75°C = 7.8 min) compared to water activity of 0.65 (D70°C = 3.9 min and D75°C = 2.0 min). D-values of E. faecium were significantly higher than those of Salmonella at all three water activities, indicating that E. faecium is a suitable surrogate for Salmonella in thermal processing validation.

Abstract
Carbon fiber ionization (CFI)-mass spectrometry (MS) is an ambient technique that can be used to detect samples in gas, liquid, and solid forms simply by using a piece of carbon fiber as the ionization emitter. Reactive MS can be performed to selectively detect target analytes by conducting fast reactions during ionization. Most ambient ionization MS techniques used to monitor chemical reactions are limited to liquid-phase reactions. Herein, we develop reactive CFI-MS to be a suitable tool for monitoring of reaction products derived from volatile unsaturated hydrocarbons in the gas phase. Hydroamination is a fast reaction that can form a carbon-nitrogen bond through the addition of an amine to unsaturated hydrocarbons. In this study, reactive CFI-MS was used to selectively characterize aroma molecules, which are unsaturated hydrocarbons derived from plants, through hydroamination. A piece of carbon fiber was placed close (~ 1 mm) to the inlet of the mass spectrometer and deposited with dried methylamine. The sample in either liquid or solid form was placed underneath the carbon fiber. The volatiles derived from the sample reacted with amine on the carbon fiber were simultaneously determined once the mass spectrometer was switched on. For proof of concept, ethylene glycol dimethacrylate, which has double bonds and is highly volatile, was initially selected as the model sample to demonstrate the feasibility of using reactive CFI-MS to detect its hydroamination derivative. Banana, garlic, and ginger, which possess aroma molecules with unsaturated hydrocarbons, were selected as real-world samples. Graphical abstract.

Abstract
The production of entire male pigs is an alternative to surgical castration. However, boar taint may be present in the meat of entire male animals. The aim of the present paper was to investigate the acceptability and sensory properties of chorizo, elaborated under three different levels of androstenone [castrated 0-0.3 mg / kg, medium 0.4-0.9 mg / kg and high 1-2.75 mg / kg] and two masking strategies [rosemary, and rosemary plus smoking] using a Check-All-That-Apply questionnaire. The results showed that, of the strategies employed, the rosemary plus smoked chorizo was the most effective masking strategy to reduce the boar taint in chorizos with high androstenone level (3.7% selection rate for animal flavour), while the closest to the ideal product, according to consumers' description, was high androstenone level plus rosemary chorizo.

Abstract
Recalls of spice containing products due to undeclared peanut have highlighted the importance of analytical methods in these foods. We examined the performance of peanut detection methods in cumin and garlic, focusing on quantitative ELISA. Although suitable for qualitative detection, accurate quantitation proved difficult. Roasting of peanut contaminants influenced ELISA results, with raw peanut over-detected (3.9-fold) and roasted peanut under-detected (3.5-fold). Further investigation demonstrated the importance of protein targets for ELISA. The kit which gave the least variable results was based on detection of 2S albumin proteins. Additionally, we show that these proteins are more efficiently extracted from roasted peanut. We conclude that current methods are largely suitable for the qualitative detection of peanut in cumin and garlic. Quantitation relies on assumptions as to the state of thermal processing of peanut. We suggest that analytical method providers address robust detection by target selection, including identifying targets by MS.

Abstract
This Review covers the background, pharmacology, adverse effects, synthesis, pharmacokinetics, metabolism, and history of synthetic cannabinoid compounds. Synthetic cannabinoids are a class of novel psychoactive substances that act as agonists at cannabinoid receptors. This class of compounds is structurally diverse and rapidly changing, with multiple generations of molecules having been developed in the past decade. The structural diversity of synthetic cannabinoids is supported by the breadth of chemical space available for exploitation by clandestine chemists and incentivized by attempts to remain ahead of legal pressures. As a class, synthetic cannabinoid products have a more serious adverse effect profile than that of traditional phytocannabinoids, including notable risks of lethality, as well as a history of dangerous adulteration. Most synthetic cannabinoids are rapidly metabolized to active species with prolonged residence times and peripheral tissue distribution, and analytical confirmation of use of these compounds remains challenging. Overall, the emergence of synthetic cannabinoids serves as a noteworthy example of the pressing public health challenges associated with the increasing development of easily synthesized, structurally flexible, highly potent, psychoactive drugs.

Abstract
Purpose
The purpose of this paper is to explore the various ways users of synthetic cannabinoids (SCs) managed the dangers associated with the consumption of this substance.
Design/methodology/approach
This paper is based on a parent study of the use and market of synthetic cathinones (also known as “bath salts”) in New York City, Houston, Galveston and New Orleans. Focus groups were conducted in all four cities with a total of 20 individuals who identified as users of SCs. Grounded theory was used to analyse focus group transcripts.
Findings
Participants were aware of drug-related risks and implemented strategies to reduce harm to health. Protective measures fell into two broad categories: marketing and consumption. They noted the instability of SC products and consumer manipulation through packaging. Harm reduction (HR) strategies included: carefully selecting SC sources; sticking to one brand; handling their own SC; managing amount of K2 consumed in one sitting; controlling the pace.
Originality/value
Given the small amount of data on user experience with SCs and its risk to health, it is important to learn from users themselves how they create methods to keep themselves safe. This is one of the first studies recording HR practices of SC users and can contribute to intervention programs and organisations serving substance users.

Abstract
BACKGROUND Nutmeg is a spice common to many kitchens around the world and is being used for many other reasons, such as an aphrodisiac, antimicrobial, antioxidant and analgesic, yet little is known about the toxic effects of nutmeg. CASE REPORT A case is presented of a young male who took an overdose of nutmeg and presented via ambulance to the Emergency Department with multiple psychiatric and neurological symptoms. The case is described in detail, especially in regard to the prehospital and Emergency Department presentation. Emergency personnel should be aware of nutmeg toxicity due to its ability to mimic many other neurological, cardiac and psychiatric conditions. Therefore, increased awareness of this issue can help minimize the risk of misdiagnosis. The importance of communication between the Emergency personnel and the pre-hospital team is stressed. A discussion is included concerning the pathophysiology of nutmeg toxicity, its history, symptomatology, differential diagnosis and treatment.

Abstract
Piperine, the principle pungent compound in black peppers, is known to activate the capsaicin receptor TRPV1 ion channel. How piperine interacts with the channel protein, however, remains unclear. Here we show that piperine binds to the same ligand-binding pocket as capsaicin but in different poses. There was no detectable detrimental effect when T551 and E571, two major sites known to form hydrogen bond with capsaicin, were mutated to a hydrophobic amino acid. Computational structural modeling suggested that piperine makes interactions with multiple amino acids within the ligand binding pocket, including T671 on the pore-forming S6 segment. Mutations of this residue could substantially reduce or even eliminate piperine-induced activation, confirming that T671 is an important site. Our results suggest that the bound piperine may directly interact with the pore-forming S6 segment to induce channel opening. These findings help to explain why piperine is a weak agonist, and may guide future efforts to develop novel pharmaceutical reagents targeting TRPV1.

Abstract
Essential oils (EOs) are known for their antioxidant properties, and are widely employed in the food industry as preservatives. They can be used as condiments or as preservatives to achieve certain organoleptic effects for consumers. The aim of this research was to evaluate antioxidant activity in mixtures of three EOs: Apium graveolens L., Thymus vulgaris L. and Coriandrum sativum L., using the Simplex Lattice Mixture Design. Ultimately, a linear model was used, as it best adjusted to the experimental behavior, and it allowed the prediction of EOs mixtures antioxidant activity, determined by FRAP and ABTS techniques. The mixture of the three EOs that showed the best antioxidant activity and also had the highest synergistic effect, was composed of 66.7% of T. vulgaris, 16.7% of C. sativum and 16.7% of A. graveolens. The greatest contribution to the potentiation of antioxidant activity was shown by T. vulgaris followed by A. graveolens and then C. sativum.

Abstract
In recent years, growing attention has been given to traditional medicine. In traditional medicine a large number of plants have been used to cure neurodegenerative diseases such as Alzheimer's disease (AD) and other memory related disorders. Crocus sativus (C. sativus), Nigella sativa (N. sativa), Coriandrum sativum (C. sativum), Ferula assafoetida (F. assafoetida), Thymus vulgaris (T. vulgaris), Zataria multiflora (Z. multiflora) and Curcuma longa (C. longa) were used traditionally for dietary, food additive, spice and various medicinal purposes. The Major components of these herbs are carotenoids, monoterpenes and poly phenol compounds which enhanced the neural functions. These medicinal plants increased anti-oxidant, decreased oxidant levels and inhibited acetylcholinesterase activity in the neural system. Furthermore, neuroprotective of plants occur via reduced pro-inflammatory cytokines such as IL-6, IL-1β, TNF-α and total nitrite generation. Therefore, the effects of the above mentioned medicinal and their active constituents improved neurodegenerative diseases which indicate their therapeutic potential in disorders associated with neuro-inflammation and neurotransmitter deficiency such as AD and depression.

Abstract
The chief psychoactive constituent of many bioactive phytocannabinoids (Δ9-tetrahydrocannabinol, Δ9-THC) found in hemp, cannabis or marijuana plants are scientifically denoted by the Latin term, Cannabis sativa, acts on cell surface receptors. These receptors are ubiquitously expressed. To date, two cannabinoid receptors have been cloned and characterized. Cannabinoid receptor type 1 (CB1R) is found to serve as the archetype for cannabinoid action in the brain. They have attracted wide interest as the mediator of all psychoactive properties of exogenous and endogenous cannabinoids and they are abundantly expressed on most inhibitory and excitatory neurons. Recent evidence established that cannabinoid receptor type 2 (CB2R) is also expressed in the neurons at both presynaptic and postsynaptic terminals and are involved in neuropsychiatric effects. Distinct types of cells in many regions in the brain express CB2Rs and the cellular origin of CB2Rs that induce specific behavioral effects are emerging. To mimic the bliss effects of marijuana, synthetic cannabinoids (SCBs) have been sprayed onto plant material, and this plant material has been consequently packaged and sold under brand name “Spice” or “K2”. These SCBs have been shown to maintain their affinity and functional activity for CB1R and CB2R and have been shown to cause severe harmful effects when compared to the effects of Δ9-THC. The present review discusses the potential brain mechanisms that are involved in the deleterious effects of SCBs.

Abstract
The analysis of synthetic cannabinoid compounds in a urine sample is currently one of the more complex tasks facing toxicologists. The list of prevalent compounds in circulation at any given time is constantly in flux, changing at a rapid rate to avoid legal control and to a lesser extent to avoid detection. Even with knowledge of the chemical entities, their detection in urine is complicated by the fact that they are present exclusively as both phase I metabolites and phase II conjugates. With proper knowledge of the correct analytical targets, relatively simple procedures are capable of extracting and analyzing synthetic cannabinoids. Following enzymatic hydrolysis, compounds can be extracted through liquid partitioning procedures, and the extracts are analyzed via LC-MS/MS.

Abstract
Synthetic cannabinoids, popularly called Spice, are common drugs of abuse in the United States. They are utilized as a substitute for marijuana, primarily for their psychoactive properties. Consumption has been rapidly increasing due to recreational effects, easy accessibility, and not being detectable by urine drug screening tests. The side effect profile of synthetic cannabinoids involves many organs and is not well known to the public. Psychoses are a common adverse result from their consumption. Primary care physicians and other medical professionals should consider synthetic cannabinoid consumption in the differential diagnoses of a patient presenting with psychosis.

Abstract
BACKGROUND Synthetic cannabinoids (SCs) are a class of new psychoactive substances that have been rapidly evolving around the world throughout recent years. Many different synthetic cannabinoid analogues are on the consumer market and sold under misleading names, like "spice" or "incense." A limited number of studies have reported serious health effects associated with SC use. In this study, we compared clinical and subclinical psychopathological symptoms associated with SC use and natural cannabis (NC) use. METHODS A convenience sample of 367 NC and SC users was recruited online, including four validated psychometric questionnaires: The Drug Use Disorders Identification Test (DUDIT), Insomnia Severity Index (ISI), Altman Mania Scale (Altman), and Brief Symptom Inventory (BSI). The two groups were compared with analysis of variance (ANOVA) and covariance (ANCOVA), chi2 tests, and logistic regression when appropriate. RESULTS The SC user group did not differ in age from the NC user group (27.7 years), but contained less females (21% and 30%, respectively). SC users scored higher than NC users on all used psychometric measures, indicating a higher likelihood of drug abuse, sleep problems, (hypo)manic symptoms, and the nine dimensions comprising the BSI, somatization, obsessive-compulsive behavior, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. Odds ratios (95% CI) for the SC user group vs NC user group were, respectively, drug dependence 3.56 (1.77-7.16), (severe) insomnia 5.01 (2.10-11.92), (hypo-)mania 5.18 (2.04-13.14), and BSI psychopathology 5.21 (2.96-9.17). DISCUSSION This study shows that SC use is associated with increased mental health symptomatology compared to NC use.

Abstract
Synthetic cannabinoid (SC) products have gained popularity as abused drugs over the past decade in many countries. The SCs broadly impact psychological state (e.g., mood, suicidal thoughts and psychosis) and physiological functions (e.g., cardiovascular, gastrointestinal and urinary). This review is about the effects of SCs on psychotic symptoms in clinical settings and the potentially relevant chemistry and mechanisms of action for SCs. Induction of psychotic symptoms after consuming SC products were reported, including new-onset psychosis and psychotic relapses. The role of SCs in psychosis is more complex than any single chemical component might explain, and these effects may not be a simple extension of the typical effects of cannabis or natural cannabinoids.

Abstract
Humans and animals are constantly exposed to crude petroleum contaminated diets in petroleum producing areas of the world. As a result, researches are on-going to find simple ameliorative agent against crude petroleum contaminated diet toxicity. The aim of this study was to evaluate the protective effect of Monodora myristica on some biochemical parameters of rats fed with crude petroleum oil contaminated catfish diet (CPO-CCD). Thirty male albino rats were separated into six groups of five rats as follows: group 1: control, group 2: rats were fed CPO-CCD only, group 3: CPO-CCD plus 1 ml/kg of 1 % tween 80, group 4: CPO-CCD plus M. myristica water extract (MWE), group 5: CPO-CCD plus M. myristica ethanol extract (MEE) and group 6: CPO-CCD plus M. myristica diethyl ether extract (MDEE). The feeding of the rats with CPO-CCD and administration of extracts orally lasted for 28 days. The results showed significant (P < 0.05) increase in aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) in the serum and tissues (liver, kidney and brain) and decrease in total protein, albumin and globulin in the serum and liver of group 2 and 3 when compared with group 1. Significant (P < 0.05) decrease in AST, ALT, ALP activities and increase in total protein, albumin and globulin levels were observed after treatment with M. myristica extracts (group 4, 5, and 6) when compared with group 1. However, it could be concluded that MDEE revealed a strong effect when compared with the MEE and MWE.

Abstract
Inhibitory effects of the powders of paprika, red pepper, black pepper, sage, oregano and thyme in a solid medium after heat treatment and gamma-irradiation on the development from spore of Bacillus subtilis were examined using calorimetry. Based on the f(t) curve (Antoce et al., 1996) from the thermogram obtained, two parameters, the growth rate constant and the growth retardation time, were used to evaluate the inhibitory effect. The inhibitory effects of paprika and red pepper powders were enhanced by the spore pretreatment with heat, but not significantly with irradiation. The inhibitory enhancement by preheating depended upon the kind of spices used. Sage, oregano and thyme powders per se inhibited the development from spores completely even at a low concentration of 0.04 g/ml. Inhibitory effects of paprika and red pepper powders were obviously observed with heat treatment but not with irradiation. With black pepper powder, by contrast, substantial enhancement was neither observed with heat treatment nor gamma-irradiation. The results suggested that the addition of those spice powders might be useful in the thermal inactivation process of solid foods contaminated with Bacillus subtilis spores.

Abstract
OBJECTIVE To characterize the clinical presentation and hospital course of patients with reported synthetic cannabinoid (SC) exposure requiring Intensive Care Unit (ICU) admission. DESIGN Retrospective case series of patients admitted to medical or cardiac ICU. SETTING Urban tertiary care center. PARTICIPANTS Adults ≥18 years old admitted from the emergency department (ED) in 2015. MEASUREMENTS Demographics, Sequential Organ Failure Assessment (SOFA) scores, and clinical parameters documenting the effects and hospital course. RESULTS 23 patients met inclusion criteria. Median age was 47 years (interquartile range [IQR], 32-54); 83% male; 78% black. Patients were generally tachycardic (HR > 100), (65%) and hypertensive (SBP > 140), (65%) on admission. The initial chest X-ray and ECG were abnormal in 43% and 68% of patients, respectively. Pulmonary edema and tachycardia were the most common findings. Head CT imaging was abnormal in 5% of patients. Troponin was elevated >1.0 ng/ml in 3 of 19 patients (16%). Other exposures detected on admission were marijuana (30%), alcohol (30%), and benzodiazepines (26%). The median SOFA score was 6 on admission and decreased over the next 3 days. SOFA scores were primarily driven by altered neurologic status and respiratory failure. 91% required mechanical ventilation, 30% had seizures as a part of presentation, 18% required vasopressors, and 5% needed dialysis. Median hospital and ICU lengths of stay were 2.6 (IQR 1.4-3.5) and 1.6 (IQR 0.9-2.5) days, respectively. The median hospital charge was $37,008. All patients survived the index hospitalization. CONCLUSIONS Patients admitted to ICU after SC exposure exhibit significant organ dysfunction, particularly neurologic and respiratory. Prognosis is good with supportive care.

Abstract
Synthetic cannabinoids (SCs) are consumed as legal alternative to cannabis and often allow passing drug-screening tests. Their rapid transience on the drug scene, combined with their mostly unknown metabolic profiles, creates a scenario with constantly moving analytical targets, making their monitoring and identification challenging. The development of fast screening strategies for SCs, not directly focused on their chemical structure, as an alternative to the commonly applied target acquisition methods, would be highly appreciated in forensic and public health laboratories. An innovative untargeted metabolomics approach, focused on herbal components commonly used for 'spice' products, was applied. Saliva samples of healthy volunteers were collected at pre-dose and after smoking herbal components and analysed by high-resolution mass spectrometry. The data obtained, combined with appropriate statistical analysis, allowed to highlight and elucidate two markers (scopoletin and N,N-bis(2-hydroxyethyl)dodecylamine), which ratio permitted to differentiate herbal smokers from non-smokers. The proposed strategy will allow discriminating potential positives, on the basis of the analysis of two markers identified in the herbal blends. This work is presented as a step forward in SC drug testing, promoting a smart first-line screening approach, which will allow reducing the number of samples to be further investigated by more sophisticated HRMS methods. Graphical abstract The development of an alternative, generic screening methods of synthetic cannabinoids, not directly based on the chemical structure, in order to provide fast response on its potential consumption.

Abstract
The use of synthetic cannabinoid has been increasing throughout the world and has become a major public health problem. The present study aims to investigate the attention, memory, visuospatial and executive functions in individuals with synthetic cannabinoid use disorder and compare the results with findings obtained from individuals with cannabis use disorder and healthy volunteers with no substance use. Fifty-two patients with synthetic cannabinoid use disorder, 45 patients with cannabis use disorder and 48 healthy control group males were included in the study. The neuropsychological test battery was designed to involve ten studies evaluating a large series of cognitive functions. Impairments in attention, memory, executive and visuospatial functions were identified in individuals with synthetic cannabinoid use disorder and these impairments were found to be significantly greater than in individuals with cannabis use disorder and healthy controls. In line with the data obtained from this study; the evaluation of each cognitive function with more comprehensive test batteries and supporting these evaluations with sensitive brain imaging studies are important topics for future research.

Abstract
There is a broad research interest in the search for alternatives to chemical additives for use as natural food preservatives. Although many natural compounds have biological in vitro properties evidenced, in situ studies are still scarce. This study evaluated the effect of oregano essential oil (OEO) and salt (NaCl) concentrations against Escherichia coli (ATCC 8739), in salad dressing, using the response surface methodology. The experiment included a 22 central composite rotatable design (CCRD) in a total of 11 formulations of salad dressings. Oregano essential oil was characterized by gas chromatography and salad dressings by ash, lipids, proteins and moisture. OEO was composed mainly by carvacrol (65.1%) and p-cymene (12.0%). Salad dressings showed similar chemical profiles. A mathematical model for the prediction of the antibacterial activity in salad dressing was obtained. The results revealed that the interaction between OEO and salt showed effect on the bacterial count. However, the effect of salt was negative suggesting that the highest NaCl concentrations decreases the bacterial count. Therefore, within the parameters studied, the use of OEO to control E. coli in salad dressing can be considered promising and allows reduction in the levels of salt to be incorporated in food.

Abstract
Synthetic cannabinoids refer to a wide variety of chemicals engineered to bind cannabinoid receptors (CB1 and CB2) and mimic the effects of delta-9-tetrahydrocanabinol. The potential for severe toxicity and limited in vivo data make synthetic cannabinoid intake an important public health and safety concern. Neurologic toxidromes associated with their use include mental status changes, panic attacks, memory distortions, acute psychosis (e.g. paranoia, delusional thoughts), disorganized behavior, and suicidal and homicidal thoughts. Systemic complications include vomiting, sinus tachycardia, myocardial infarction, and acute kidney injury. Seizures are common; however, status epilepticus is not widely reported. In this case report, we describe a patient who developed acute psychosis and new-onset refractory status epilepticus necessitating emergent neurological life-support and prolonged admission to an intensive care unit following abuse of synthetic cannabinoids. We include a brief review of the literature to prepare the treating clinician for the broad clinical spectrum of this increasingly common intoxication.

Abstract
Black pepper (Piper nigrum) is among the most popular spices around the world. Starch is the major component of black pepper. However, little is known about functional properties of this starch. In this study, swelling, solubility, thermal properties, rheology, and enzyme susceptibility of 2 black pepper starches were studied and compared with those of maize starch. Pepper starch had lower water solubility and swelling power than maize starch. It had higher viscosity during pasting event. In dynamic oscillatory analysis, pepper starch had lower storage modulus. Thermal analysis showed that pepper starch had much higher gelatinization temperatures (e.g., conclusion temperature of 94°C) than maize starch. The susceptibility to α-amylolysis of pepper starch was not very different from that of maize starch. Overall, the differences in the physicochemical properties of the 2 pepper starches are non-significant. The relationships between structure (especially amylopectin internal molecular structure) and properties of starch components are highlighted.

Abstract
The U.S. Food and Drug Administration conducted a survey to evaluate Salmonella prevalence and aerobic plate counts in packaged (dried) spices offered for sale at retail establishments in the United States. The study included 7,250 retail samples of 11 spice types that were collected during November 2013 to September 2014 and October 2014 to March 2015. No Salmonella-positive samples (based on analysis of 125 g) were found among retail samples of cumin seed (whole or ground), sesame seed (whole, not roasted or toasted, and not black), and white pepper (ground or cracked), for prevalence estimates of 0.00% with 95% Clopper and Pearson's confidence intervals of 0.00 to 0.67%, 0.00 to 0.70%, and 0.00 to 0.63%, respectively. Salmonella prevalence estimates (confidence intervals) for the other eight spice types were 0.19% (0.0048 to 1.1%) for basil leaf (whole, ground, crushed, or flakes), 0.24% (0.049 to 0.69%) for black pepper (whole, ground, or cracked), 0.56% (0.11 to 1.6%) for coriander seed (ground), 0.19% (0.0049 to 1.1%) for curry powder (ground mixture of spices), 0.49% (0.10 to 1.4%) for dehydrated garlic (powder, granules, or flakes), 0.15% (0.0038 to 0.83%) for oregano leaf (whole, ground, crushed, or flakes), 0.25% (0.03 to 0.88%) for paprika (ground or cracked), and 0.64% (0.17 to 1.6%) for red pepper (hot red pepper, e.g., chili, cayenne; ground, cracked, crushed, or flakes). Salmonella isolates were serotyped, and genomes were sequenced. Samples of these same 11 spice types were also examined from shipments of imported spices offered for entry to the United States from 1 October 2011 to 30 September 2015. Salmonella prevalence estimates (based on analysis of two 375-g composite samples) for shipments of imported spices were 1.7 to 18%. The Salmonella prevalence estimates for spices offered for sale at retail establishments for all of the spice types except dehydrated garlic and basil were significantly lower than estimates for shipments of imported spice offered for entry.

Abstract
Forty one samples of herbal spices intended to be introduced into the European market and seized by the French customs were analysed with high-field 1H NMR. Nine synthetic cannabinoids (MAM-2201, JWH-073, JWH-210, JWH-122, JWH-081, JWH-250, UR-144, XLR-11 and AKB-48-5F) were detected and quantified. The ability of a compact benchtop low-field NMR spectrometer for a rapid screening of the content of herbal blends was then successfully explored for the first time. Even if low-field 1H NMR spectra are much less resolved than high-field spectra, we demonstrate that they provide valuable clues on the chemical structures of synthetic cannabinoids with the detection of some typical signals.

Abstract
INTRODUCTION Synthetic cannabinoid (SC) abuse has resulted in numerous outbreaks of severe clinical illness across the United States over the past decade. The primary objective of this study was to determine the clinical characteristics of patients abusing SC requiring bedside consultation by medical toxicologists. METHODS This was a multicenter analysis from a prospectively collected cohort of patients presenting to medical care after synthetic cannabinoid exposure, utilizing the ToxIC Registry. Management of cases by medical toxicologists in this cohort occurred in emergency departments, inpatient medical floors, and intensive care units. Cases were identified from January 5, 2010 - July 31, 2015. We characterized the clinical presentations, treatments, outcomes, and sociologic factors associated with SC use in these patients. RESULTS Medical toxicologists participating in the ToxIC Registry cared for 39,925 cases between 2010 and 2015. Three hundred fifty three of these cases were determined to be SC toxicity. The median age of patients was 25 (IQR: 18, 36) and the majority were males (84%). The most common symptoms were agitation, delirium and toxic psychosis, n=146 (41%). Forty-four (12.5%) had heart rates above 140 beats per minute. Bradycardia was the second most commonly reported severe vital sign abnormality with 20 (5.7%) having heart rates of less than 50 beats per minute. Fifteen (4.2%) patients had hypotension. Fifty-nine (17%) had seizures. The most common pharmacologic treatment provided was benzodiazepines (n=131, 37%) followed by antipsychotics (n=36, 10%).Disposition was available for 276; of these 167 (61%) were managed in the emergency department, 42 (15%) were admitted to the hospital floor, and 67 (24%) were admitted to the ICU. CONCLUSIONS Synthetic cannabinoids are associated with severe central nervous system and cardiovascular effects.

Abstract
The purpose of the study was to evaluate three real-time PCR platforms for rapid detection of Salmonella from cloves and to compare three different DNA extraction methods. Six trials were conducted with two clove cultivars, Ceylon and Madagascar, and three Salmonella serotypes, Montevideo, Typhimurium, and Weltevreden. Each trial consisted of 20 test portions. The preenrichment cultures were used to perform PCR for comparison of the effectiveness of U.S. Food and Drug Administration, Pacific Regional Laboratory Southwest (FDA-PRLSW), Applied Biosystems Inc. (ABI) MicroSEQ, and GeneDisc platforms for detection of Salmonella. Three DNA extraction methods were used: standard extraction method for each PCR platform, boil preparation, and LyseNow food pathogen DNA extraction cards. The results from real-time PCR correlated well with FDA Bacteriological Analytical Manual culture assay results, with a wide range of cycle threshold (CT) values among the three PCR platforms for intended positive samples. The mean CT values for MicroSEQ (16.36 ± 2.78) were significantly lower than for PRLSW (20.37 ± 3.45) and GeneDisc (23.88 ± 2.90) (P < 0.0001). Pairwise comparisons between PCR platforms using different DNA extraction methods indicate that the CT values are inversely proportional to the relative DNA quantity (RDQ) yields by different platform-extraction combinations. The pairing of MicroSEQ and boil preparation generated the highest RDQ of 120 and the lowest average CT value of 14.48, whereas the pairing of GeneDisc and LyseNow generated the lowest RDQ of 0.18 and the highest average CT of 25.97. Boil preparation yielded higher RDQ than the other extraction methods for all three PCR platforms. Although the MicroSEQ platform generated the lowest CT values, its sensitivity was compromised by narrow separations between the positive and negative samples. The PRLSW platform generated the best segregation between positive and negative groups and is less likely to produce false results. In conclusion, FDA-PRLSW was the most efficient PCR assay for Salmonella detection, and boil preparation was the best method for DNA extraction.

Abstract
It is critically important to identify all factors that may play a role in the recent increase of the incidence of stroke among the young population. Considering the worldwide use of cannabinoids (cannabis and synthetic cannabinoids), the recent legalization of their consumption in some countries, and their supposed involvement in cardiovascular events, we evaluated their role in the occurrence of neurovascular complications among the young. Ninety-eight patients were described in the literature as having a cannabinoids-related stroke (85 after cannabis use and 13 after synthetic cannabinoids). The distribution by type of stroke was as follows: 4 patients with an undetermined type of stroke, 85 with an ischemic stroke and/or a transient ischemic attack, and 9 with a hemorrhagic stroke. The mean age of patients was 32.3±11.8years (range 15-63), and the majority of them were male with a sex ratio of 3.7:1. Cannabis was often smoked with tobacco in 66% of cases. Most of the patients with cannabinoids-related strokes were chronic cannabis users in 81% of cases, and for 18% of them, there was a recent increase of the amount of cannabis consumption during the days before the occurrence of stroke. Even if the prognosis of stroke was globally favorable in 46% of cases, with no or few sequelae, 5 patients died after the neurovascular event. One striking element reported in the majority of the reports was a temporal relationship between cannabinoids use, whether natural or synthetic, and the occurrence of stroke. However, a temporal correlation does not mean causation, and other factors may be involved. Cannabis may be considered as a risk factor of stroke until research shows evidence of an underlying mechanism that, alone or in association with others, contributes to the development of stroke. As of today, reversible cerebral vasoconstriction triggered by cannabinoids use may be a convincing mechanism of stroke in 27% of cases. Indeed, despite the widespread use of cannabinoids, the low frequency of neurovascular complications after their use may be due to a genetic predisposition to their neurovascular toxicity in some individuals. Further studies should focus on this point. More importantly however, this low frequency may be underestimated because the drug consumption may not be systematically researched, neither by questioning nor by laboratory screening. Besides this vascular role of cannabinoids in the occurrence of stroke, a cellular effect of cannabis on brain mitochondria was recently suggested in an experimental study. One of the mechanisms involved in young cannabis users with stroke may be the generation of reactive oxygen species leading to an oxidative stress, which is a known mechanism in stroke in humans. It is useful to inform the young population about the real potential risk of using cannabinoids. We suggest to systematically ask all young adults with stroke about their drug consumption including cannabinoids, to screen urine for cannabis or to include a specific diagnostic test to detect synthetic cannabinoids, and to obtain non-invasive intracranial arterial investigations (i.e. CT-angiography or cerebral MRA) in order to search for cerebral vasoconstriction. However, several questions remained unresolved and further research is still needed to assess the pathophysiological mechanisms involved in young cannabinoids users with stroke. This article is part of a Special Issue entitled "Cannabinoids and Epilepsy".
