Comparative efficacy of imidocarb dipropionate with additive in naturally infected cattle against bovine babesiosis

Babesiosis is a tick borne disease prevalent worldwide. The present study was planned to evaluate the therapeutic efficacy of imidocarb dipropionate alone and with additive milk, cumin, and jetepar syrup in naturally Babesia-infected cattle. Blood samples (n = 300) were collected from the selected cattle. Age, breed, dung pile location, use of acaricides, temperature, health status, tick infestation and housing type were also considered during sample collection. Out of 90 samples that were found positive through staining procedures, 45 were confirmed through PCR. As per infection rate observed more in exotic breed, the treatment trials were conducted on these cattle. These cattle were divided into three groups, each consisting of 15 cattle. Group 1 was treated with imidocarb dipropionate. Group 2 was treated with imidocarb dipropionate and additives (milk, cumin, and jetepar syrup). Group 3 was the infected, non-medicated group, and group 4 consisted of healthy, non-infected cattle (n = 15).The cattle were subjected to liver function tests and recorded milk production before and after treatment. The afore-mentioned factorsi.e. age (<3 years), Holstein Friesian breed, with dung piles near their living area, without acaricides use, poor health status, tick infestation, and tethered housing system were found significant associated with babesiosis in the cattle. Cattle in G1 treated with imidocarb dipropionate showed an efficacy of 60 %. G2, on the other hand, showed 90 % efficacy. The cattle in G3, did not recover and two died. All cattle in G4, remained health. It was concluded that the cattle treated with imidiocarb dipropionate as well as additives showed better and rapid recovery.

Insects as Source of Nutraceuticals with Antioxidant, Antihypertensive, and Antidiabetic Properties: Focus on the Species Approved in Europe up to 2024

Insects represent a traditional food in different parts of the world, where eating insects is not only related to nutrition, but also results from a variety of sociocultural customs. Insects' nutritional profiles typically vary by species. Nevertheless, in terms of nutrition, edible insects can be a rich source of protein, dietary fiber, healthy fatty acids, and micronutrients, including minerals and vitamins. Insects have a low carbon footprint and require fewer resources in terms of land, water, and food with respect to animal livestock. Interestingly, insects are a source of bioactive compounds with different pharmacological activities, including antioxidant, antimicrobial, antidiabetic, antiobesity, antihypertensive, and antilipidemic. Among the bioactive compounds, polyphenols, chitosan, and protein hydrolysates are the most important ones, with direct activity on ROS quenching and enzymatic inhibition. Glucosidase, DPP-IV, ACE, and lipases are directly inhibited by insects' bioactive peptides. Lipids and tocopherols reduce inflammation and lipid peroxidation by acting on LOX and COX-2 enzymes and on ROS quenching. The insects' nutrient composition, coupled with their easy and economical breeding, is the cause of the growing interest in edible insects. During the last 20 years, the study and development of novel insect-based products increased, with relevant effects on the market. This review focuses on the edible insects currently approved in Europe, namely, Acheta domesticus, Alphitobus diaperinus, Locusta migratoria, and Tenebrio molitor. The nutrient profile and the functional compounds are examined, with an eye on market trends and on the patent applications filed in the last decades.

Advancements and Challenges in Sucralose Determination: A Comparative Review of Chromatographic, Electrochemical, and Spectrophotometric Methods

This review presents an in-depth analysis of the latest methods used for the determination of sucralose (E955), focusing on research conducted over the past 10 years. As a widely used sugar substitute in the food and pharmaceutical industries, sucralose has raised concerns about its environmental persistence, potential genotoxicity, and health impacts. This study examines several spectrophotometric, chromatographic, and electrochemical techniques, evaluating their sensitivity, selectivity, and limitations in differentiating sucralose from natural carbohydrates and other sweeteners. The review highlights the pressing need for novel detection methods that not only improve accuracy in trace detection but also address growing concerns about its bioaccumulation and conversion into harmful metabolites. Advancing these analytical techniques is essential for enhancing food safety, public health surveillance, and environmental risk assessment. Chromatographic methods are dominant in sucralose determination in foods and environmental objects, as they allow the determination of sucralose at micro- and nanomolar levels. However, spectrophotometric and electrochemical methods are frequently used as complementary to chromatographic methodologies, sensitizing them. On the other hand, purely spectrophotometric methods are less popular, and electrochemical methods remain underdeveloped. Therefore, the advancement of sucralose determination must be due to cheaper chromatographic and classical electrochemical methods.

The regulatory module MdCPCL-MdILR3L mediates the synthesis of ascorbic acid and anthocyanin in apple

Apple (Malus domestica Borkh.) is one of the most economically valuable fruit crops globally and a key dietary source for various nutrients. However, the levels of ascorbic acid (AsA) and anthocyanin, essential micronutrients for human health, are extremely low in the pulp of commonly cultivated apple varieties. In the present study, the second-generation hybrid strain of Xinjiang red-fleshed apple ('Zihong No. 1' × 'Gala') was used as the test material. The results revealed that AsA content was significantly higher in red-fleshed apple pulp than in non-red-fleshed varieties, and the expression of MdGLDH, a key gene in the D-mannose/L-galactose pathway, correlated strongly with AsA levels. Using the promoter of MdGLDH as bait, an R3-type MYB transcription factor (TF), MdCPC-like, was identified through yeast one-hybrid screening. Further analysis revealed that the overexpression of MdCPCL increased the AsA and anthocyanin levels in both callus and fruits, whereas MdCPCL knockdown led to a reduction in their levels. Moreover, the interaction between MdCPCL and the bHLH TF MdILR3-like was confirmed, forming the MdCPCL-MdILR3L complex. This complex significantly enhanced the transcription of downstream target genes MdGLDH and MdANS, promoting the synthesis of AsA and anthocyanins. This study contributes to further enrich the anabolic pathways of AsA and anthocyanin in apples and provides a theoretical foundation for the quality breeding of red-fleshed apple varieties.

The effect of hot air treatment on volatile compounds in nectarine fruit and the regulation of glycosidically bound compounds by sugar

In order to investigate the impact of hot air (HA) treatment on the sugars and volatiles in postharvest nectarine fruit, nectarines were treated with HA at 40 °C for 4 h and stored at 1 °C for 35 days. Changes of sugars, free and glycosidically bound volatiles, β-glucosidase (β-Glu) activity, and the gene expression of UGT (UDP-glucosyltransferase) in nectarine fruit were determined. The results showed that compared with CK, HA treatment delayed the firmness decline of 48.01%, weight loss of 32.13%, internal browning index of 58.03%, and maintained the high commodity quality of nectarine fruit at the end of storage. HA could reduce the content of aldehydes and increase the content of esters. The bound linalool in HA increased by 171.41% compared with the CK. In addition, the results of in vitro experiments showed that glucose and sucrose systems could increase the content of free and bound linalool by up-regulating the expression of PpUGT85A2, promoted the accumulation of bound benzaldehyde and nonanal, and reduced the corresponding free volatile compounds, it showed that free aldehydes can be synthesized from soluble sugars into bound aldehydes.

Beta-carotene-loaded Oleogels: Morphological analysis, cytotoxicity assessment, in vitro digestion and intestinal permeability

Composition and structure of oleogels significantly influence their digestive behaviour, impacting triacylglycerol breakdown and the bioavailability of incorporated compounds. Texture profile analysis showed that sterol-based oleogels (STOs) exhibited 20 times higher hardness than beeswax-based oleogels (BWOs), which showed stronger cohesion due to elasticity sustained by adhesive forces. Tribological assessments revealed similar initial coefficients of friction (COF) for both oleogels. However, fluctuations were observed in BWOs and a gradual decrease in STOs over time, enhancing lubrication, while BWOs recorded higher adhesion. These findings provide insights into their distinct digestive behaviour, with both oleogels undergoing structural disintegration and STOs displaying a higher lipolysis degree. Non-cytotoxicity was confirmed under Caco-2 cells. β-carotene bioaccessibility was influenced by the oleogels' structural modification and values of 4.0 ± 0.7 % for STOs and 2.6 ± 1.1 % for BWOs were recorded. Results highlight the need to optimize formulations to improve bioactive's bioavailability, emphasizing the role of structured gels in modulating digestion dynamics.

In recent years, the exploration of bioactive molecules derived from natural sources has gained interest in several application fields. Among these, macroalgae have garnered significant attention due to their functional properties, which make them interesting in therapeutic applications, including cancer treatment. Cancer constitutes a significant global health burden, and the side effects of existing treatment modalities underscore the necessity for the exploration of novel therapeutic models that, in line with the goal of reducing drug treatments, take advantage of natural compounds. This review explores the anticancer properties of macroalgae, focusing on their bioactive compounds and mechanisms of action. The key findings suggest that macroalgae possess a rich array of bioactive compounds, including polysaccharides (e.g., fucoidans and alginates), polyphenols (e.g., phlorotannins), and terpenoids, which exhibit diverse anticancer activities, such as the inhibition of cell proliferation, angiogenesis, induction of apoptosis, and modulation of the immune system. This review provides an overview of the current understanding of macroalgae's anticancer potential, highlighting the most promising compounds and their mechanisms of action. While preclinical studies have shown promising results, further research is necessary to translate these findings into effective clinical applications.

Global burden of cardiovascular diseases attributable to diet low in vegetables from 1990 to 2021 and forecasting the future trends: a population-based study

BACKGROUND

This investigation examines the worldwide impact of cardiovascular diseases (CVD) resulting from inadequate vegetable consumption, based on the 2021 Global Burden of Disease Study data.

METHOD

The study assessed the global, regional, and national repercussions of low vegetable intake on CVD, with a focus on variations among different age and gender demographics. It further analyzed the correlation between disease burden and the Socio-Demographic Index (SDI), and employed an ARIMA model to predict future trends in CVD associated with insufficient vegetable consumption up to 2050.

RESULT

In 2021, a diet lacking in vegetables was responsible for roughly 682,400 deaths and 16 million disability-adjusted life years (DALYs) attributed to CVD, indicating a declining pattern over recent year. Individuals aged 75 and older were predominantly affected. Future projections indicate an expected rise in CVD incidence in lower-middle SDI regions, with African nations potentially experiencing increased challenges related to low vegetable consumption by 2030 and 2050.

CONCLUSION

The findings underscore the critical necessity for preventive measures against CVD and emphasize the significance of improving dietary habits, particularly vegetable intake.

Grape pomace and pecan shell fortified bread: The effect of dietary fiber-phenolic compounds interaction on the in vitro accessibility of phenolic compounds and in vitro glycemic index

Grape pomace (GP) and pecan shell (PS) are two by-products rich in phenolic compounds (PC), and dietary fiber (DF) that may be considered for the development of functional baked foods. In this study, four formulations with different GP:PS ratios (F1(8%:5%), F2(5%:5%), F3(5%:2%), F4(0%:5%), and control bread (CB)) were elaborated and characterized (physiochemical and phytochemical content). Also, their inner structure (SEM), changes in their FTIR functional group's vibrations, and the bioaccessibility of PC and sugars, including an in vitro glycemic index, were analyzed. Results showed that all GP:PS formulations had higher mineral, protein, DF (total, soluble, and insoluble), and PC content than CB. Additionally, PC and non-starch polysaccharides affected gluten and starch absorbance and pores distribution. In vitro digestion model showed a reduction in the glycemic index for all formulations, compared to CB. These findings highlight the possible health benefits of by-products and their interactions in baked goods.

The association between animal protein, plant protein, and their substitution with bladder cancer risk: a pooled analysis of 10 cohort studies

PURPOSE

Although total dietary protein intake has been associated with bladder cancer (BC) risk, the effect of the origin (plant or animal) and the substitutions remain to be understood. This study aimed to investigate the effect of total dietary protein, animal-based protein, plant-based protein, and their substitutions with each other on the risk of BC using a pooled analysis of 10 cohort studies.

METHODS

The study was conducted within the "BLadder cancer Epidemiology and Nutritional Determinants" (BLEND) study, including 10 prospective cohort studies from several European countries, the United Kingdom, and the United States. Individual data from 10 prospective cohorts containing 434,412 participants (overall male/female ratio was almost 3:1) with a total of 4,224,643.8 person-years of follow-up was analyzed. Hazard ratios (HRs) and 95% confidence intervals (CIs) for BC risk for animal and plant-based protein substitutions of 30gram (g) per day (g/day) were estimated by multivariable adjusted HRs using Cox proportional hazards models.

RESULTS

During 11.4 years of follow-up, among 434,412 participants (73.28% female), 1,440 new cases of BC were identified. After multivariable adjustment, no association was observed between the intake of total, animal-based protein, and plant-based protein and BC risk. Replacement of every 30 g/day of animal-based protein intake by the same amount of plant-based protein intake or vice versa was not associated with the risk of BC.

CONCLUSION

In conclusion, our study found no association between protein intake-whether from animal or plant sources-and the risk of BC. Substituting animal-based protein with plant-based protein, or the reverse, did not influence BC risk. Future studies are required to provide information on the link between animal- and plant-based proteins and BC risk.

Mulberry (Fructus mori) extract alleviates hyperuricemia by regulating urate transporters and modulating the gut microbiota

Mulberry (Fructus mori) is a traditional Chinese fruit that has beneficial effects due to its numerous biological activities. This study aimed to investigate the anti-hyperuricemic activity and underlying mechanism of laboratory-prepared mulberry water extract in mice with hyperuricemia (HUA). Additionally, the effect of mulberry extract (ME) on the microbiota was investigated. The results demonstrated that ME reduced the levels of HUA-related biochemical indices [uric acid (UA), creatinine (Cr), and blood urea nitrogen (BUN)] and pro-inflammatory factors (TNF-α, IL-6, IL-8, and IL-1β) in the serum of HUA model mice. ME suppressed xanthine oxidase (XOD) and adenosine deaminase (ADA) activity while modulating the expression of the urate transporters ATP-binding cassette transporter G2 (ABCG2) and recombinant urate transporter 1 (URAT1) in the kidney. Furthermore, high-dose ME modulated the microbiota, including Ligilactobacillus, Prevotellaceae, Bacteroides and Desulfovibrio. Overall, these results demonstrate the efficacy of ME in alleviating HUA by inhibiting XOD and ADA activity, as well as modulating transport proteins to decrease urate synthesis. Additionally, ME regulates the microbiota associated with host UA metabolism. These findings confirm the UA-lowering effects of ME, highlighting its potential as a therapeutic agent for HUA.

Metabolomic analysis of rice cultivars from diverse production areas

Rice grown in Yunnan Province is known for its excellent taste and consumer preference. However, the metabolite composition of this unique rice remains unclear. In this study, the metabolic profile of different rice planted in various producing regions was evaluated. A total of 1,005 metabolites were identified, including nucleotides and their derivatives, amino acids and their derivatives, alkaloids, organic acids, phenolic acids, lignans and coumarins, lipids, terpenoids, quinones, flavones, tannins, and others. Procucing region and varieties can be clearly distinguished on the PCA diagram. Differential metabolites accumulated in the MSD502 vs. MSR88 (138)/LHHG (234)/LHR88 (188) comparison groups. The results in this study provide scientific information for the origin tracing and variety differentiation of raw rice materials.

Exploring the Effect of Resveratrol, Tyrosol, and Their Derivatives on Platelet-Activating Factor Biosynthesis in U937 Cells

Platelet-activating factor (PAF) is a potent lipid mediator, involved in thrombosis, inflammation, and atherosclerosis. The protective effect of wine and olive oil against atherosclerotic diseases is largely attributed to their phenolic compounds and mostly to resveratrol and tyrosol. Both compounds have been reported to inhibit PAF biosynthesis in interleukin-1β (IL-1β)-stimulated monocytes and also to attenuate PAF biosynthesis in cell lysates. The aim of this study was to investigate the effects of resveratrol, tyrosol, and their derivatives on unstimulated U937 cells and to explore the intracellular messaging pathways that participate in the activation of PAF biosynthesis in the same cell line. Tyrosol and its derivatives did not exert any substantial effect on PAF biosynthesis. Resveratrol (50 and 100 μM), as well as its methoxy derivative (5-20 μM), caused a reduction in the PAF biosynthetic enzymes' activity by 20-43% after 24 h of incubation. On the other hand, lower resveratrol concentration (10 μM) and higher concentration of the methoxy derivative (50 μM) increased the Ca2+-dependent lyso-PAF acetyltransferase (LysoPAF-ATC) activity by 28-45% after half-hour incubation via p38 mitogen-activated protein kinase (p38-MAPK) action. IL-1β activated PAF biosynthetic pathways via different signaling pathways, with phospholipase C-β (PLC-β) being a key enzyme.

Genomic and metabolomic insights into the selection and differentiation of bioactive compounds in citrus

Bioactive compounds play an increasingly prominent role in breeding functional and nutritive fruit crops such as citrus. However, the genomic and metabolic bases for the selection and differentiation underlying bioactive compound variations in citrus remain poorly understood. In this study, we constructed a species-level variation atlas of genomes and metabolomes using 299 citrus accessions. A total of 19 829 significant SNPs were targeted to 653 annotated metabolites, among which multiple significant signals were identified for secondary metabolites, especially flavonoids. Significant differential accumulation of bioactive compounds in the phenylpropane pathway, mainly flavonoids and coumarins, was unveiled across ancestral citrus species during differentiation, which is likely associated with the divergent haplotype distribution and/or expression profiles of relevant genes, including p-coumaroyl coenzyme A 2'-hydroxylases, flavone synthases, cytochrome P450 enzymes, prenyltransferases, and uridine diphosphate glycosyltransferases. Moreover, we systematically evaluated the beneficial bioactivities such as the antioxidant and anticancer capacities of 219 citrus varieties, and identified robust associations between distinct bioactivities and specific metabolites. Collectively, these findings provide citrus breeding options for enrichment of beneficial flavonoids and avoidance of potential risk of coumarins. Our study will accelerate the application of genomic and metabolic engineering strategies in developing modern healthy citrus cultivars.

The Role of Exogenous microRNAs on Human Health: The Plant-Human Trans-Kingdom Hypothesis

MicroRNAs (miRNAs) are small, endogenous, single-stranded RNAs that act on gene silencing at the post-transcriptional level by binding to a target messenger RNA (mRNA), leading to its degradation or inhibiting translation into functional proteins. The key role of miRNAs in development, proliferation, differentiation andapoptosis has been deeply investigated, revealing that deregulation in their expression is critical in various diseases, such as metabolic disorders and cancer. Since these small molecules initially evolved as a mechanism of protection against viruses and transposable elements, the fascinating hypothesis that they can move between organisms both of the same or different species has been postulated. Trans-kingdom is the term used to define the migration that occurs between species. This mechanism has been well analyzed between plants and their pests, in order to boost defense and increase pathogenicity, respectively. Intriguingly, in the last decades, the plant-human trans-kingdom migration via food intake hypothesis arose. In particular, various studies highlighted the ability of exogenous miRNAs, abundant in the mainly consumed plant-derived food, to enter the human body affecting gene expression. Notably, plant miRNAs can resist the strict conditions of the gastrointestinal tract through a methylation step that occurs during miRNA maturation, conferring high stability to these small molecules. Recent studies observed the anti-tumoral, immune modulator and anti-inflammatory abilities of trans-kingdom interaction between plant and human. Here, we depict the existing knowledge and discuss the fascinating plant-human trans-kingdom interaction, highlighting first the eventual role of plant miRNAs from foods on our somatic gene identity card and then the potential impact of using plant miRNAs as novel therapeutic avenues.

Biotransformation of Geraniol to Geranic Acid Using Fungus Mucor irregularis IIIMF4011

Geraniol is an important component in essential oils of aromatic plants such as lemongrass, rosa grass, and many others. It can be converted to different high-value products by using microbes/enzymes. The present study aims at the isolation and screening of microbes showing efficient production of geranic acid (a high-value product) from geraniol (a low-value monoterpene). Mucor irregularis IIIMF4011, isolated from the soil sample of Cymbopogon citratus (Lemongrass), showed biotransformation of geraniol to geranic acid. After optimization of reaction parameters, 97-100% conversion of geraniol to geranic acid was obtained after 72 h of incubation at 28 °C. Furthermore, the biotransformation reaction was also carried out in a 3 L fermentor (working volume 1.5 L), and 98.89% conversion was observed. Therefore, an efficient process of geranic acid production using M. irregularis IIIMF4011 was developed.

Integrated supercritical fluid extraction of essential oils

Supercritical fluid extraction (SFE) stands out as an incredibly efficient, environmentally conscious, and fast method for obtaining essential oils (EOs) from plants. These EOs are abundant in aromatic compounds that play a crucial role in various industries such as food, fragrances, cosmetics, perfumery, pharmaceuticals, and healthcare. While there is a wealth of existing literature on using supercritical fluids for extracting plant essential oils, there's still much to explore in terms of combining different techniques to enhance the SFE process. This comprehensive review presents a sophisticated framework that merges SFE with EO extraction methods. This inclusive categorization encompasses a range of methods, including the integration of pressurized liquid processes, ultrasound assistance, steam distillation integration, microfluidic techniques, enzyme integration, adsorbent facilitation, supercritical antisolvent treatments, molecular distillation, microwave assistance, milling process and mechanical pressing integration. Throughout this in-depth exploration, we not only elucidate these combined techniques but also engage in a thoughtful discussion about the challenges they entail and the array of opportunities they offer within the realm of SFE for EOs. By dissecting these complexities, our objective is to tackle the current challenges associated with enhancing SFE for commercial purposes. This endeavor will not only streamline the production of premium-grade essential oils with improved safety measures but also pave the way for novel applications in various fields.

The effect of water-soluble tomato concentrate on elevated serum cholesterol in the middle-aged and elderly Chinese individuals

Water-soluble tomato concentrate (WSTC) has demonstrated beneficial effect on blood flow in healthy populations. The prospective, randomized, double-blind, and placebo-controlled clinical trial was conducted to explore the impact of WSTC on individuals with elevated cholesterol levels. Sixty participants aged 35-65 with high cholesterol were enrolled and evenly divided into a treatment group (FFG) and a placebo group (PCG). Over a 60-day period comprising a 45-day treatment phase followed by a 15-day observational follow-up. Participants in the FFG received 300 mg daily of Fruitflow tablets, while the PCG were received placebos. The study showed that there were no significant differences in baseline parameters between the FFG and PCG (p > 0.05). Post-intervention, the FFG exhibited significant reductions in systolic blood pressure (SBP) and diastolic blood pressure (DBP) by 4.2% (SBP, p < 0.001) and 3.8% (DBP, p = 0.015), respectively, compared to the PCG (p = 0.041). These reductions were sustained during the follow-up period. In contrast, the PCG showed no significant changes in SBP and DBP (p > 0.05). Stratified analysis by hypertension status revealed a significant SBP reductions both hypertensive and non-hypertensive FFG subjects (p < 0.05), with a trend towards DBP reduction. No significant changes in SBP and DBP were observed in the PCG. Moreover, the FFG group showed a significant increase in high-density lipoprotein (HDL) cholesterol (p < 0.05), along with a marked reduction in both weight and body mass index (BMI) (p < 0.05). The FFG also showed decreased levels of homocysteine, high-sensitivity C-reactive protein, and fasting blood glucose compared to the PCG (p < 0.05). In conclusion, WSTC has the potential to lower blood pressure and cardiovascular risk profiles in hypercholesterolemic individuals, presenting a viable non-harmacological option for enhancing cardiovascular health.

Multitargeted pharmacokinetics, molecular docking and network pharmacology-based identification of effective phytocompounds from Sauropus androgynus (L.) Merr for inflammation and cancer treatment

According to worldwide health data, cancer, and inflammatory illnesses are on the rise and are among the most common causes of death. Across the world, these types of health problems are now considered top priorities for government health organizations. Hence, this study aimed to investigate medicinal plants' potential for treating cancer and inflammatory disorders. This network pharmacology analysis aims to learn more about the potential targets and mechanisms of action for the bioactive ingredients in Sauropus androgynus (L.) Merr L. The compound-target network and protein-protein interaction analysis were built using the STRING database. Using Network Analyst, Gene Ontology, and Kyoto Encyclopaedia of Genes and Genomes, pathway enrichment was performed on the hub genes. 1-hexadecanol was shown to inhibit drug-metabolizing enzymes in a pharmacokinetic investigation. Those samples of 1-hexadecanol were found to be 1-hexadecanol (BBB 0.783), GI High, Pgp Substrate Yes, CYP2C19 Inhibitor Yes, CYP2D6 Yes, and HI -89.803. The intermolecular binding energies for 1-hexadecanol (4-DRI, -8.2 kcal/mol) are evaluated. These results from a study on S. androgynus used molecular docking and network pharmacology to gain insight into the prime target genes and potential mechanisms identified for AKT1, mTOR, AR, PPID, FKBP5, and NR3C1. The PI3K-Akt signalling pathway has become an important regulatory node in various pathological processes requiring coordinated actions. Stability and favourable conformations have been resolved by considering nonbonding interactions such as electrostatic and hydrogen bonds in MD simulations of the perfect molecules using the Desmond package. Thus, using an appropriate platform of network pharmacology, molecular docking, and in vitro experiments, this study provides for the first time a clearer knowledge of the anti-cancer and anti-inflammatory molecular bioactivities of S. androgynus. Further in vitro and in vivo confirmations are strongly needed to determine the efficacy and therapeutic effects of 1-hexadecanol in the biological process.Communicated by Ramaswamy H. Sarma.

Associations of dietary flavonoid intake with the risk of all-cause and cardiovascular mortality in adults

BACKGROUND AND AIMS

Flavonoids are widely distributed polyphenolic compounds in the diet that possess various health-promoting effects. This study aimed to investigate the association between dietary flavonoid intake and all-cause and cardiovascular mortality in adults.

METHODS AND RESULTS

The data on the six main subclasses of flavonoids, including isoflavones, anthocyanidins, flavan-3-ols, flavanones, flavones, and flavonols, were obtained from the 2007-2010 National Health and Nutrition Examination Survey (NHANES) dataset of adults. The participants were followed up until December 30, 2019. Cox regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for dietary flavonoid intake and mortality. The study included a total of 8758 adults (mean age 44.00 years; 47.40% men). A median follow-up of 10.7 years yielded 1113 all-cause deaths and 261 cardiovascular deaths were recorded. In comparison to category 1, category 4 of flavan-3-ols, flavonols, and total flavonoids were associated with lower risks of all-cause mortality, with multivariable-adjusted HRs of 0.71 (95% CI: 0.55-0.92, Ptrend = 0.021), 0.58 (95% CI: 0.45-0.74, Ptrend<0.001), and 0.63 (95% CI: 0.50-0.80, Ptrend = 0.010), respectively. Similarly, higher intake of category 4 flavonoids was associated with a reduced risk of cardiovascular mortality, with HRs of 0.68 (95% CI: 0.29-0.89, Ptrend = 0.035) for flavones, 0.41 (95% CI: 0.22-0.78, Ptrend = 0.001) for flavonols, and 0.54 (95% CI: 0.36-0.80, Ptrend = 0.021) for total flavonoids.

CONCLUSION

Dietary flavonoid intake is associated with all-cause and cardiovascular mortality. Increasing dietary flavonoid intake may reduce the risk of death in adults.

Total Polyphenol Contents and Mineral Profiles in Commercial Wellness Herbal Infusions: Evaluation of the Differences between Two Preparation Methods

The popularity of the consumption of wellness herbal teas is due to the many health-promoting properties they seem to possess. Modern preparation methods using coffee machines are also popular today. Therefore, the purpose of this research was to evaluate differences in infusions obtained by the traditional method using filters and by espresso coffee machines using pods. In this regard, different herbal materials were selected and purchased in two different types of herbal containers, and the corresponding infusions were analyzed for the contents of total polyphenols and mineral elements. Results showed that filter infusions had higher polyphenol and mineral contents than pod infusions, excluding Cd and Pb. For each of the plant materials used, differences due to the method of infusion preparation are highlighted. From a qualitative point of view, both methods of infusion preparation are valid, but the filter infusion method allows a higher transfer of minerals and polyphenols into the infusion, improving quality. The analyzed infusions can be safely consumed with respect to As, Cd, Pb, and Hg contents. Good amounts of polyphenols and Mn can be obtained by drinking a cup of any of the infusions analyzed, especially the mate infusion obtained by the filter technique, with amounts of 429 mg for polyphenols and 69.27% of the RDA for manganese.

Exploring the antioxidant potential of Moringa oleifera leaf extracts mitigating doxorubicin-induced cardiotoxicity in male rats

Doxorubicin (DOX) is a commonly used drug in chemotherapy for cancer treatment. However, it can cause the threatening side effect of cardiotoxicity. This study investigates whether the hydro-alcoholic leaves of Moringa oleifera have any protective potential against DOX-induced cardiotoxicity. The phytochemical analysis showed that the plant extracts contained bioactive compounds with antioxidant activities. The DOX-treated group confirmed a significant increment in cardiac troponin I (cTnI) and proinflammatory cytokine interleukin-6 (IL-6) levels, which indicates damage to the cardiomyocytes and also inflammation. However, treatment with the M. oleifera extracts significantly inhibited DOX-induced cardiomyocyte damage, as indicated by the significantly low cTnI release. Furthermore, treatment with M. oleifera extracts further increased antioxidant activities, thereby decreasing oxidative stress and lipid peroxidation. Moreover, DOX was found to increase the IL-6 level, and treatment with M. oleifera extracts had a significant impact on the inhibition of IL-6 levels. These results indicate that the M. oleifera extracts have a cardioprotective effect and can play a role as an adjunct drug in mitigating DOX-induced cardiotoxicity, thus providing new prospects for the improvement of safety and efficacy in the treatment of cancer.

Ginkgo biloba extract mitigates the neurotoxicity of AlCl3 in alzheimer rat's model: role of apolipoprotein E4 and clusterin genes in stimulating ROS generation and apoptosis

PURPOSE

Alzheimer's disease (AD) appears as a result of an increase in the accumulation of amyloid beta peptide (Aβ) and a decrease in neurotransmitters (acetylcholine) within the brain cells which may be due to increase in acetylcholinesterase (AchE) activity and change in expression of Apolipoprotein E4 (ApoE4) and Clusterin (Clu) genes. The aim of the present study was using natural products such as Ginkgo biloba (G. biloba) extract that has the potential to reduce Aβ formation and increase AchE inhibition with its ability to save neuronal DNA from damage.

METHODS

Sixty male aged rats were divided into six experimental groups exposed to AlCl3 to induce AD model and were treated with G. biloba extract. Collected brain tissues were used to assess the apoptosis rate, reactive oxygen species (ROS) generation, AchE inhibitory activity, expression alteration in ApoE4 and Clu genes, DNA fragmentations and gutathione peroxidase (GPx) activity.Results: The results exhibited that rats exposed to AlCl3 increased significantly rate of apoptosis, ROS formation, DNA fragmentation, up-regulation of ApoE4 and Clu genes as well as decrease of AchE inhibitory activity and GPx activity compared with those in control rats. However, treatment of AlCl3-rats with G. biloba extract improved the above neurotoxicity results induced by AlCl3 exposure.

CONCLUSIONS

It is therefore likely that G. biloba extract's protective properties against AD are due to its ability to activate the response against oxidative stress.

Analysis of Quantitative Phytochemical Content and Antioxidant Activity of Leaf, Stem, and Bark of Gymnosporia senegalensis (Lam.) Loes

To the best of our knowledge, there was no prior report providing valuable preliminary data through a demonstration of the quantitative phytochemical and antioxidant activity of Gymnosporia senegalensis. The total contents of phenols, flavonoid, flavanol, tannin, and saponin were evaluated from different fractions extracted from the leaf, stem, and bark of G. senegalensis by using standards such as gallic acid, quercetin, rutin, tannic acid, and saponin quillaja. The antioxidant potential was measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide scavenging (H2O2), superoxide anion radical scavenging, metal chelating ferrous ion, ferric reducing antioxidant power (FRAP), and total antioxidant capacity (TAC). Data were subjected to half-inhibitory concentration (IC50) and one-way analysis of variance (ANOVA) at p < 0.05 as a significant value. The total phenol content was found to be highest in the chloroform extract of stem at 97.7 ± 0.02 mg GAE/g. The total flavonoid and flavonol contents in the aqueous extract were 97.1 ± 0.03 mg QE/g and 96.7 ± 0.07 mg RE/g, respectively. The total tannin content in the ethyl acetate extract of leaf was 97.5 ± 0.01 mg TAE/g, and the total saponin content in the methanol extract of stem was 79.1 ± 0.06 mg SQE/g. The antioxidant analysis indicated that IC50 and percentage (%) inhibition were dose-dependent and showed the highest antioxidant activity (40.9 ± 0.9 µg/mL) in methanol extract of leaf for DPPH, (88.8 ± 1.12 µg/mL) in the chloroform extract of stem for H2O2, (43.9 ± 0.15 µg/mL) in the aqueous extract of bark for superoxide anion radical scavenging activity, (26.9 ± 0.11 µg/mL) in the chloroform extract of leaf for the metal chelating ferrous ion activity, (7.55 ± 0.10 mg/mL) in the benzene extract of leaf for FRAP, and (2.97 ± 0.01 mg/mL) in the methanol extract of bark for TAC. These results show that G. senegalensis has great potential in antioxidant activities. The isolation and characterization of specific bioactive compounds and the in vivo applicability of such activity await further extensive studies for drug discovery and development.

Synthesis and characterization of marine seagrass (Cymodocea serrulata) mediated titanium dioxide nanoparticles for antibacterial, antibiofilm and antioxidant properties

Cymodocea serrulata mediated titanium dioxide nanoparticles (TiO2 NPs) were successfully synthesized. The XRD pattern and FTIR spectra demonstrated the crystalline structure of TiO2 NPs and the presence of phenols, flavonoids and alkaloids in the extract. Further SEM revealed that TiO2 NPs has uniform structure and spherical in shape with their size ranged from 58 to 117 nm. Antibacterial activity of TiO2 NPs against methicillin-resistant Staphylococcus aureus (MRSA) and Vibrio cholerae (V. cholerae), provided the zone of inhibition of 33.9 ± 1.7 and 36.3 ± 1.9 mm, respectively at 100 μg/mL concentration. MIC of TiO2 NPs against MRSA and V. cholerae showed 84% and 87% inhibition at 180 μg/mL and 160 μg/mL respectively. Subsequently, the sub-MIC of V. cholerae demonstrated minimal or no impact on bacterial growth at concentration of 42.5 μg/mL concentration. In addition, TiO2 NPs exhibited their ability to inhibit the biofilm forming V. cholerae which caused distinct morphological and intercellular damages analysed using CLSM and TEM. The antioxidant properties of TiO2 NPs were demonstrated through TAA and DPPH assays and exposed its scavenging activity with IC50 value of 36.42 and 68.85 μg/mL which denotes its valuable antioxidant properties with potential health benefits. Importantly, the brine shrimp based lethality experiment yielded a low cytotoxic effect with 13% mortality at 100 μg/mL. In conclusion, the multifaceted attributes of C. serrulata mediated TiO2 NPs encompassed the antibacterial, antioxidant and anti-biofilm inhibition effects with low cytotoxicity in nature were highlighted in this study and proved the bioderived TiO2 NPs could be used as a promising agent for biomedical applications.

Protective Effects of Cereal Grain Extracts on Alcohol-Induced Hepatocyte Damage

This study investigated the protective effects of cereal grains on alcohol-induced hepatocyte damage. Cereal grains were extracted with methanol, and their radical scavenging properties and total phenolic contents were examined. Black rice extract exhibited the highest total polyphenol content and radical scavenging capacity. Treatment with sorghum extract increased the viability of cells exposed to alcohol by up to 81.6%. All cereal grain extracts decreased reactive oxygen species and malondialdehyde production and glutathione depletion in HepG2 cells exposed to ethanol. In particular, black rice and sorghum extracts exhibited greater antioxidant effects than other cereal grains. Treatment with black rice extract increased the levels of alanine aminotransferase and aspartate aminotransferase of alcohol-exposed cells to control levels. Overall, black rice extract showed a greater protective effect compared with other cereal grains against alcohol exposure in HepG2 cells and could improve alcohol-induced liver problems.

Health-promoting benefits of lentils: Anti-inflammatory and anti-microbial effects

This paper describes how lentils (Lens culinaris species) can positively affect health by reducing inflammation, providing antioxidants, and displaying antimicrobial properties. Lentils are rich in proteins, essential amino acids, minerals, and fibers, making them a valuable source of nutrition, particularly in low and middle-income countries. Lentils have many health benefits, including positive effects on diabetes management, support for cardiovascular health, and antioxidative properties. The antioxidative properties of lentils, attributed to their phenolic content, and their ability to inhibit inflammation-related enzymes are also discussed. We discuss the potential of lentils as a dietary tool in promoting immunity, reducing disease burdens, and preventing nutritional deficiencies. Overall, lentils are a highly nutritious food with various health benefits, including anti-inflammatory and antimicrobial effects. The fiber and protein content in lentils make them beneficial for weight management, blood sugar regulation, and supporting overall gut health. Furthermore, the slow rate at which lentils affect blood sugar levels, due to their low glycemic index, can be advantageous for individuals with diabetes.

Bee Bread as a Functional Product: Phenolic Compounds, Amino Acid, Sugar, and Organic Acid Profiles

Bee bread (perga) is a natural bee product formed by the fermentation of the pollen collected by bees via lactic acid bacteria and yeasts. This study aims to determine the bioactive compounds, amino acid, sugar, and organic acid profile of bee bread samples collected from the Ardahan province of Türkiye. The highest total phenolic, total flavonoid, and DPPH values in bee bread samples were determined as 18.35 mg GAE/g, 2.82 mg QE/g, and 3.90 mg TEAC/g, respectively. Among phenolic compounds, gallic acid had the highest value at 39.97 µ/g. While all essential amino acids except tryptophan were detected in the samples, aspartic acid was the most dominant, followed by pyrroline and glutamic acid. Among sugars, fructose was seen at the highest level. Succinic acid, among organic acids, had the highest amount at 73.63 mg/g. Finally, all the data were subjected to a principal components analysis (PCA). Bee bread samples were grouped according to the analysis results of the districts they were collected from. This study provides information about the bioactive components and some chemical properties of bee bread, a natural product that has been the subject of recent research. It also contains essential data for future functional food production.

Analysis of ingredient list and nutrient composition of plant-based burgers available in the global market

The nutrient composition of plant-based burgers is a key factor when making their purchase/consumption decision to maintain a balanced diet. For this reason, ingredient list and nutritional information of burgers launched in the global market were retrieved from their labels. Products were classified based on the technology development, market position and region of the manufacturer. From the ingredient analysis, we observed a high heterogeneity in the ingredients used, a predominance of soy and wheat as main sources of proteins, and the increasing use of new protein sources (e.g. peas, other types of beans and pseudo-cereals). Oil was the most cited ingredient followed by salt. Nutritional composition varied mainly depending on the region with no clear pattern among countries. To less extent, technology development resulted in traditional products with lower amounts of protein and higher amounts of carbohydrates. Vegan and vegetarian products showed limited differences due to the high intra-heterogenicity.

Nutritional characteristics of Stereospermum chelonoides (L.f.) DC., an underutilized edible wild fruit of dietary interest

Malnutrition and hunger is a serious global issue, however, wild fruits possess the potential of combatting it being rich in nutrients. Stereospermum chelonoides (L.f.) DC., commonly known as "Patala" in Ayurvedic text, is a large wild tree bearing edible, yet, underutilized fruits consumed by the locals in Western parts of India and neighboring countries. The present study focuses on the nutritional profile of S. chelonoides fruit along with quantification of bioactive constituents using RP-HPLC-PDA and evaluation of in-vitro anti-oxidant and, anti-microbial activity. The fruit was found rich in nutritional composition having protein (2.41 % ± 0.007), fibre (3.46 % ± 0.02) and carbohydrate (90.19 % ± 1.73) with energy value of 368.2 ± 3.94 Kcal/100g. The elemental analysis of fruit resulted in macronutrients Ca, Mg and Na and micronutrients Fe, Mn, Zn, and Cu in amounts comparable to common marketed fruits. The RP-HPLC-PDA analysis revealed the presence of six phenolic compounds in all 3 extracts made from the fruit in which highest amount are present in hydro-alcoholic extract. All the extracts exhibited potent antioxidant activity evaluated through DPPH assay and oxygen radical absorbing capacity (ORAC), with highest activity in hydro-alcoholic extract. All the analyzed extracts also exhibited potent inhibition, against four human pathogens namely Pseudomonas aeruginosa, Vibrio cholerae, Escherichia coli, and Shigella flexneri. Therefore, it is evident from the study that the fruit of S. chelonoides has immense potential as a nutraceutical supplement and may help in the management of nutrient deficiency and malnutrition among rural and tribal communities.

Luteolin prevents TNF-α-induced NF-κB activation and ROS production in cultured human placental explants and endothelial cells

INTRODUCTION

Preeclampsia (PE) is a serious hypertensive pregnancy disorder and a leading cause of maternal and perinatal morbidity and mortality. Despite the prevalence and complications, there are no approved therapeutics to relieve PE symptoms. Inflammation, oxidative stress, and angiogenic imbalance have been shown to contribute to the PE pathophysiology, though there is a lack of understanding in how best to target these pathways in PE. We recently demonstrated that the bioflavonoid luteolin is a potent inhibitor of the anti-angiogenic and pro-hypertensive soluble fms-like tyrosine kinase 1 (sFlt-1), and here we aimed to determine if luteolin was also capable of reducing inflammation and oxidative stress pathways.

METHODS

Tumor necrosis factor (TNF)-α, which is upregulated in PE, was utilized to stimulate these pathways in human placental explants and endothelial cells. Endothelin-1 (ET-1) and interleukin (IL)-6 in the media from explants and cells were measured via ELISA, and NF-κB localization and reactive oxygen species were detected via fluorescence microscopy.

RESULTS

Pretreatment with luteolin demonstrated significant reductions in NF-κB activation, reactive oxygen species, superoxide, and IL-6 and ET-1 expression in endothelial cells. We also saw a significant reduction in phosphorylation of NF-κB in human placental explants.

DISCUSSION

These data demonstrate that luteolin inhibits pathways implicated in the development of PE and should be explored further for its potential as a PE therapeutic.

Phytotherapeutics in Cancer: From Potential Drug Candidates to Clinical Translation

Annually, a significant number of individuals succumb to cancer, an anomalous cellular condition characterized by uncontrolled cellular proliferation and the emergence of highly perilous tumors. Identifying underlying molecular mechanism(s) driving disease progression has led to various inventive therapeutic approaches, many of which are presently under pre-clinical and/or clinical trials. Over the recent years, numerous alternative strategies for addressing cancer have also been proposed and put into practice. This article delineates the modern therapeutic drugs employed in cancer treatment and their associated toxicity. Due to inherent drug toxicity associated with most modern treatments, demand rises for alternative therapies and phytochemicals with minimal side effects and proven efficacy against cancer. Analogs of taxol, Vinca alkaloids like vincristine and vinblastine, and podophyllotoxin represent a few illustrative examples in this context. The phytochemicals often work by modifying the activity of molecular pathways that are thought to be involved in the onset and progression of cancer. The principal objective of this study is to provide an overview of our current understanding regarding the pharmacologic effects and molecular targets of the active compounds found in natural products for cancer treatment and collate information about the recent advancements in this realm. The authors' interest in advancing the field of phytochemical research stems from both the potential of these compounds for use as drugs as well as their scientific validity. Accordingly, the significance of herbal formulations is underscored, shedding light on anticancer phytochemicals that are sought after at both pre-clinical and clinical levels, with discussion on the opportunities and challenges in pre-clinical and clinical cancer studies.

Encapsulating potential and functional properties of exopolysaccharide from Limosilactobacillus reuteri KCTC 14626BP isolated from human breast milk

Exopolysaccharides (EPS) are natural, nontoxic, biocompatible and biodegradable macromolecules produced by microorganisms, including the Lactic acid bacteria, to enhance protection against environmental stress conditions. The current study focused on the encapsulation and functional efficiency of EPS produced by probiotic strains isolated from human milk. Among 27 isolates, the potential high EPS-producing strain Limosilactobacillus reuteri KCTC 14626BP was selected based on biofilm production. The structural Characterization of EPS was performed based on FTIR, NMR and functional properties were determined; further, the encapsulation efficiency of EPS was determined with caffeic acid. The results indicate that L. reuteri produced EPS major component consisting of glucose, galactose and arabinose with the ratio of (0.78:0.16: 0.05). The antioxidant efficiency of EPS-LR was determined on DPPH (60.3 %) and ABTS (48.9 %); EPS showed enhanced functional activities. The absence of toxicity was confirmed based on Caenorhabditis elegans. The EPS-loaded Caffeic acid (CA) EPS-LR indicated spherical capsules with rough surfaces, with sizes ranging from 1.39 to 6.75 μm. These findings indicate that EPS-LR can be applied as a bioactive compound and encapsulating material in food, cosmetics, and pharmaceutical industries.

Enhancement of the organic acid content and antioxidant capacity of yellow whey through fermentation with Lacticaseibacillus casei YQ336

Fermentation is considered an effective tool for improving the functional characteristics of food. In this study, Lacticaseibacillus casei YQ336 was used to ferment yellow whey, and physical and chemical analysis was performed to identify the changes in the nutritional components and antioxidant activity of the fermented yellow whey. Non-targeted metabolomics was used to study the transformation of small molecular substances in the fermented yellow whey. After 48 h of pure culture fermentation with L. casei YQ336, the pH of yellow whey decreased significantly (p < 0.05). Meanwhile, the content of total acids, organic acids, sugars, total phenols, and total flavonoids and the antioxidant activity showed a significant increase (p < 0.05). A total of 628 differential metabolites were identified between fermented and unfermented yellow whey samples, of which 293 were upregulated and 335 were downregulated. After fermentation, due to the growth and metabolic activity of L. casei YQ336, meaningful metabolites such as homovanillic acid, lactic acid, oxalic acid, L-glutamic acid, and phenylalanine, as well as phenyllactic acid, gallic acid, and genistein were produced. This increased the organic acid content and antioxidant activity of yellow whey. The findings provide a theoretical and practical basis for further research on the bio-functional activity of yellow whey and the recycling and utilization of food by-products.

Assessment of Chemical Composition and In Vitro Antioxidant, Antidiabetic, Anticholinesterase and Microbial Virulence-Quenching Effects of Salad Burnet (Sanguisorba minor L.) Harvested from Algeria

Sanguisorba minor is a medicinal vegetable used in seasoning desserts, juices, and beverages. An evaluation of the total flavonoid, phenolic, tannin and anthocyanin contents indicated that these classes of compounds are distributed variably in the different fractions. In summary, the HPLC-DAD analyses enabled the identification and quantification of thirteen phenolic compounds in an ethyl acetate extract (EAE), nine in a dichloromethane extract (DCME), seven in an aqueous extract (AQE) and four in a butanol extract (BE). Rutin was the most abundant phenolic compound in the BE (278.4 ± 1.20 µg/g) and AQE (32.87 ± 0.23 µg/g) fractions, while apigenin was the most abundant in the DCME (84.75 ± 0.60 µg/g) and EAE (156.8 ± 0.95 µg/g) fractions. The presence of phenolic compounds in the fractions conferred good antioxidant capacity, especially the EAE and DCME fractions, which both exhibited higher antioxidant effects than BHA and α-tocopherol in DPPH• and CUPRAC assays. Additionally, in the ABTS•+ assay, EAE (IC50 = 9.27 ± 0.33 µg/mL) was more active than α-tocopherol (IC50 = 35.50 ± 0.55 µg/mL), and BHA (IC50 = 12.70 ± 0.10 µg/mL). At 200 µg/mL, the fractions inhibited acetylcholinesterase and butyrylcholinesterase as well as α-amylase and α-glucosidase, indicating that they can slow neurodegeneration and hyperglycemia. Minimal inhibitory concentration (MIC) values ranged from 0.312 mg/mL to 1.25 mg/mL, and fractions showed good biofilm inhibition against Staphylococcus aureus and Escherichia coli. The extracts exhibited good violacein inhibition in Chromobacterium violaceum CV12472 and Chromobacterium violaceum CV026, despite the supply of external acyl-homoserine lactone to CV026. The antioxidant, quorum-sensing, antibiofilm and enzyme inhibition attributes indicate the potential for the application of S. minor as a food preservative.

Dietary fruits and vegetables and risk of cardiovascular diseases in elderly Chinese

BACKGROUND

Evidence regarding the potential effect of fruit and vegetable consumption on cardiovascular diseases (CVD) was limited and inconsistent among Asian people.

METHODS

We prospectively examined associations of fruit and vegetable consumption with the risk of CVD among 9740 participants aged 65 years and older (mean baseline age: 88 years) in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) (2008-2018). Dietary data were collected using a validated food frequency questionnaire.

RESULTS

During 37 366 person-years of follow-up, a total of 3738 CVD cases were recorded. After adjusting for demographics, dietary, lifestyle and economical social factors, higher intakes of total fruits and vegetables were associated with lower risk of CVD [comparing with extreme quintiles, hazard ratio and 95% confidence interval: 0.84 (0.74, 0.95)]. The inverse association was mainly driven by vegetable consumption [0.86 (0.77, 0.95)]. Furthermore, the inverse association was stronger for the risk of hypertension [0.84 (0.72, 0.98)]. These associations were consistent across age, sex, body mass index, residence, exercise status, smoking, drinking, meat intake, modified hPDI and health status.

CONCLUSIONS

This study suggests higher intakes of total fruits and vegetables are associated with a lower risk of CVD among elderly Chinese people, supporting the current recommendations of increasing fruit and vegetable consumption as part of a healthy diet for the prevention of CVD.

Impact of Baizhu, Daqingye, and Hehuanhua extracts on the human gut microbiome

Introduction

In traditional Chinese medicine, the rhizome of Atractylodes macrocephala (Baizhu), the leaves of Isatis indigotica (Daqingye), and the flowers of Albizia julibrissin (Hehuanhua) have been used to treat gastrointestinal illnesses, epidemics, and mental health issues. Modern researchers are now exploring the underlying mechanisms responsible for their efficacy. Previous studies often focused on the impact of purified chemicals or mixed extracts from these plants on cells in tissue culture or in rodent models.

Methods

As modulation of the human gut microbiome has been linked to host health status both within the gastrointestinal tract and in distant tissues, the effects of lipid-free ethanol extracts of Baizhu, Daqingye, and Hehuanhua on the human adult gut microbiome were assessed using Systemic Intestinal Fermentation Research (SIFR®) technology (n=6).

Results and discussion

Baizhu and Daqingye extracts similarly impacted microbial community structure and function, with the extent of effects being more pronounced for Baizhu. These effects included decreases in the Bacteroidetes phylum and increases in health-related Bifidobacterium spp. and short chain fatty acids which may contribute to Baizhu's efficacy against gastrointestinal ailments. The changes upon Hehuanhua treatment were larger and included increases in multiple bacterial species, including Agathobaculum butyriciproducens, Adlercreutzia equolifaciens, and Gordonibacter pamelaeae, known to produce secondary metabolites beneficial to mental health. In addition, many of the changes induced by Hehuanhua correlated with a rise in Enterobacteriaceae spp., which may make the tested dose of this herb contraindicated for some individuals. Overall, there is some evidence to suggest that the palliative effect of these herbs may be mediated, in part, by their impact on the gut microbiome, but more research is needed to elucidate the exact mechanisms.

Nut consumption and urogenital and genital, gastrointestinal and women-related cancers: Assessment and review

The prevalence of cancer, especially in industrial countries, is a major problem for health and treatment systems. Cancer can affect the quality of life of all family members and has many negative effects on the community. Despite many advances in cancer treatment, this disease is still a major worldwide problem. There is strong evidence that dietary habits are effective in protecting against cancer and even helping in the disease treatment progress. Nuts with various biologically-active compounds, such as vitamins, phytosterols, isoflavones, flavonoids, and polyphenols have been reported to possess anticarcinogenic properties. Accordingly, this review provides an insight into the association between nut consumption and the prevention of some cancers. We considered the cancers related to the urogenital and genital tract, gastrointestinal tract, as well as women-related cancers. Both cell culture examinations and experimental animal studies alongside observational epidemiological studies demonstrated that regular consumption of a nut-enriched diet is able to reduce the risk of these cancers.

Pyrethroids toxicity in vertebrates and invertebrates and amelioration by bioactive compounds: A review

Generations of different synthetic pesticides have been launched over time to maintain balance between production and consumption of the agricultural yield, control various disease programmes, store grains, etc. Pyrethroids, which are supposed to be non-toxic, have been excessively implemented and have contaminated soil and water bodies. Thus, pyrethroids cause severe and dreadful pernicious effects on various life forms residing in soil, air, and water. Various obnoxious effects of pyrethroids have been analyzed in the vertebrate and invertebrate systems of the animal kingdom. Pyrethroids, namely, Cypermethrin, Deltamethrin, Beta-cyfluthrin, Esfenvalerate, Fenvalerate, and Bifenthrin, have set out various types of degenerative and toxic impacts that include oxidative stress, hepatotoxicity, immunotoxicity involving thymic and splenic toxicity, neurotoxicity, nephrotoxicity, foetal toxicity, alterations in serum calcium and phosphate levels, cerebral and bone marrow degeneration, degeneration of the reproductive system, histological alteration, and DNA damage. Bioactive compounds like Diosmin, Curcumin, Rutin, Spirulina platensis, sesame oil, Naringin, Allicin, Piperine, alpha-lipoic acid, alpha-tocopherol, Cyperus rotundus L. tuber extract, herbal syrup from chicory and artichoke leaves, green tea extract, Quercetin, Trans-ferulic acid, Ascorbic acid, Propolis, ethanolic extract of grape pomace, and Melatonin have been reported to sublime the toxic effects of these pesticides. The expanding harmfulness of pesticides is a real and demanding issue that needs to be overcome, and bioactive compounds have been shown to reduce the toxicity in vivo as well as in vitro.

Phloretin alleviates doxorubicin-induced cardiotoxicity through regulating Hif3a transcription via targeting transcription factor Fos

BACKGROUND

Doxorubicin (Dox), a chemotherapeutic agent known for its efficacy, has been associated with the development of severe cardiotoxicity, commonly referred to as doxorubicin-induced cardiotoxicity (DIC). The role and mechanism of action of phloretin (Phl) in cardiovascular diseases are well-established; however, its specific function and underlying mechanism in the context of DIC have yet to be fully elucidated.

OBJECTIVE

This research aimed to uncover the protective effect of Phl against DIC in vivo and in vitro, while also providing a comprehensive understanding of the underlying mechanisms involved.

METHODS

DIC cell and murine models were established. The action targets and mechanism of Phl against DIC were comprehensively examined by systematic network pharmacology, molecular docking, transcriptomics technologies, transcription factor (TF) prediction, and experimental validation.

RESULTS

Phl relieved Dox-induced cell apoptosis in vitro and in vivo. Through network pharmacology analysis, a total of 554 co-targeted genes of Phl and Dox were identified. Enrichment analysis revealed several key pathways including the PI3K-Akt signaling pathway, Apoptosis, and the IL-17 signaling pathway. Protein-protein interaction (PPI) analysis identified 24 core co-targeted genes, such as Fos, Jun, Hif1a, which were predicted to bind well to Phl based on molecular docking. Transcriptomics analysis was performed to identify the top 20 differentially expressed genes (DEGs), and 202 transcription factors (TFs) were predicted for these DEGs. Among these TFs, 10 TFs (Fos, Jun, Hif1a, etc.) are also the co-targeted genes, and 3 TFs (Fos, Jun, Hif1a) are also the core co-targeted genes. Further experiments validated the finding that Phl reduced the elevated levels of Hif3a (one of the top 20 DEGs) and Fos (one of Hif3a's predicted TFs) induced by Dox. Moreover, the interaction between Fos protein and the Hif3a promoter was confirmed through luciferase reporter assays.

CONCLUSION

Phl actively targeted and down-regulated the Fos protein to inhibit its binding to the promoter region of Hif3a, thereby providing protection against DIC.

Health-promoting germinated rice and value-added foods: a comprehensive and systematic review of germination effects on brown rice

Over the last 30 years, thousands of articles have appeared examining the effects of soaking and germinating brown rice (BR). Variable germination conditions and methods have been employed to measure different health-beneficial parameters in a diverse germplasm of BR. Research results may therefore appear inconsistent with occasional anomalies, and it may be difficult to reach consensus concerning expected trends. Herein, we amassed a comprehensive review on germinated brown rice (GBR), attempting to codify 133 peer-reviewed articles regarding the effects on 164 chemical parameters related to health and nutrition in BR and in value-added food products. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-2020) approach was used to direct the flow of the literature search. A pair-wise comparison t-test was performed to deliver an overall approach indicating when a given compound has been found to significantly increase or decrease through germination, which was grouped into GABA and polyamines, γ-Oryzanol and phytosterols, phenolic compounds, vitamins, proteins and amino acids, starchy carbohydrates, free sugars, lipids, minerals and phytic acid. This resource will stimulate interest in germinating rice and optimistically help increase both production and consumption of highly nutritious, health-beneficial rice with pigmented bran.

Association of tea and its extracts with colorectal adenomas: meta-analysis and systematic review

Background

There are many studies on the association of tea and its extracts with colorectal adenomas, but the results have varied. The study aims to investigate the effect of tea and its extracts on colorectal adenomas using meta analysis and systematic review.

Methods

Literature was obtained through PubMed, Cochrane Library, Embase and Chinese BioMedical Literature Service System since the establishment of the database until April 31, 2023. Search terms include adenomas, polyps, colorectal, rectal, rectum, tea, epigallocatechin, drinking and beverages. Meta-regression analysis was used to infer the source of heterogeneity. Heterogeneity was assessed using I2 statistics and Q test. The effect measures were odds ratio (OR) and 95% confidence interval (95% CI). Stata17.0 software was used for data processing.

Results

The findings indicated that study design (t = 0.78, P = 0.454), types of tea intake (t = 1.35, P = 0.205), occurrences (t = -0.19, P = 0.852), regions (t = 1.13, P = 0.281) and grades of adenomas (t = 0.06, P = 0.952) were statistical homogeneity. Tea and its extracts were negatively correlated with the risk of colorectal adenomas (OR = 0.81, 95% CI: 0.66-0.98). No publication bias was found in this study (t = -0.22, P = 0.828) and the results are robust.

Conclusion

This study suggests that tea and its extracts have a certain protective effect on colorectal adenomas, which provides scientific evidence for preventive strategies for colorectal adenomas. As for the causal relationship between tea and its extracts on colorectal adenomas, further prospective studies are needed.
