Abstract
OBJECTIVE The Islamic Republic of Iran has displayed one of the highest rates of COVID-19 infection in the world and the highest rate of mortality in the Middle East. Iran has used a stringent package of preventive health measures to mitigate the spread of infection, which however has negatively affected individuals' physical and psychological health. This study aimed at examining whether physical-activity (PA) behavior, anxiety, well-being, and sleep-quality changed in response to the COVID-19-related public health restrictions enforced in Iran. PATIENTS AND METHODS An online questionnaire was disseminated to adults residing in Iran from November 17, 2020, to February 13, 2021 (~88 days), during Iran's strictest public health restrictions. Main outcome measures included Godin-Shephard Leisure-Time Exercise Questionnaire, General Anxiety Disorder-7, Mental Health Continuum-Short Form, and Pittsburgh Sleep Quality Index. RESULTS A total of 3,323 adults (mean age 30±11 years, 54.3% female) participated in the survey. Firstly, the restrictions generally reduced PA behavior: (a) among inactive participants (IPs), 60.6% became less active vs. 5.1% who became more active; and (b) among active participants (APs), 49.9% became less active vs. 22.8% who became more active. Secondly, PA behavior was associated with higher well-being and sleep quality during the restrictions: (a) APs reported higher (or lower) levels of well-being and sleep quality (or anxiety) than did IPs; and (b) among IPs as well as among APs, the more active the participants, the greater (or lower) the levels of well-being and sleep quality (or anxiety). CONCLUSIONS This study showed the beneficial role of PA behavior for well-being, anxiety, and sleep quality during the COVID-19 restrictions, whereas such restrictions appeared to decrease PA participation. Active lifestyle should be then encouraged during the COVID-19 outbreak while taking precautions.

Abstract
Introduction The relationship between epilepsy and depression has been recognized for a long time. In fact, the presence of depression could worsen the disease outcome. Objectives we aimed to study the prevalence of depression in patients with epilepsy and to assess the determinant factors of its genesis. Methods 54 patients with epilepsy, aged more than 18 years, attending the neurology department of Habib Bourguiba Hospital, Sfax, Tunisia, were enrolled for the study. All patients were administered Mini-International Neuropsychiatric Interview (MINI) for evalution of psychiatric comorbid disorders especially depression. Socio-demographic and clinical data were collected. Results A total of 54 patients were included, of whom 63% (n =34) were men. Mean duration of epilepsy was 20.13 years. The most frequent type of seizure was generalized 72.7%. Depression was present in 7.3 % of patients. Alcoholism (p=0.027) was significantly associated with occurrence of depression. Drug resistence (p = 0.03) and longer duration of epilepsy (p = 0.046) were significantly associated with occurrence of depression. No significant association was found between type of seizure, seizure frequency, medication compliance and depression. Depression wasn’t associated with anti-epileptic drug. We didn’t find any association between depression and other psychiatric comorbidities. Conclusions Depression wasn’t frequent in our study contrary to literature. The possible explanations are the reduced simple size and the sensitivity of the used tool to assess depression in epilepsy. Pursuant to literature, we found significant association between Alcoholism, drug resistance and long duration of epilepsy.

Abstract
Offshore fish farms have been active inside the Monastir Bay, Hammemet Gulf for over 10 years, but their environmental impact is still unknown. This study focuses on the evaluation of the fish farming activity impact in the Monastir Bay as revealed by geochemical and benthic foraminiferal data. Samples were collected around three fish cages at different water depths. Total organic carbon (TOC) and total phosphate (TP) in the sediment show higher values beneath the fish cages and decrease proportionally with distance from the cages. Living foraminiferal assemblages around fish farms are dominated by stress-tolerant species with higher abundances of Ammonia tepida, Rosalina bradyi, Elphidium crispum, and Peneroplis planatus. On the basis of our results, A. tepida and Quinqueloculina seminula are confirmed to be tolerant to elevated nutriment content, while Ammonia parkinsoniana seems to be more sensitive to organic enrichment. We also test the Foram-AMBI that is revealed to be a very promising tool by which evaluating the ecological quality status of marine sediment. The results of the present study confirm the suitability of living benthic foraminifera as bioindicators of organic enrichment induced by aquaculture activities.

Abstract
To investigate the current environment status in Monastir Bay (Tunisia), surface sediments from 32 stations were assessed for heavy metal and organic matter concentrations, and the results were compared with values of natural metal content, marine sediment quality standards, and other results concerning sediments from other Mediterranean coasts. The study of their spatial distributions refined by complementary approaches, including potential ecological risks determined through the enrichment factor, geo-accumulation index, contamination factor, potential ecological risk index, pollution load index, and principal component analysis, showed a significant impact of multiple anthropogenic sources. Moderate pollution of sediments, particularly by Ni and Cu, was also observed. Moreover, TOC values showed that the northern part of Monastir Bay is characterized by high levels of sediment organic matter because of the presence of fish farm cage. This baseline study can be used to establish background values for future sediment surveys.

Abstract
CONTEXT Despite some studies related to Juniperus phoenicea L. (Cupressaceae), phytochemical and biological investigations of this plant remain unexplored. OBJECTIVE This work is the first report dealing with the identification and characterization of volatile components and flavonoids in hexane and methanol extracts from J. phoenicea leaves Materials and methods: Antioxidant activity of hexane, and methanol extracts from J. phoenicea leaves were determined by DPPH-radical scavenging assay. α-Amylase inhibitory activity was evaluated by enzyme inhibition using in vitro assay (each extract was dissolved in DMSO to give concentrations of 50, 100 and 200 mg/mL). The chemical composition of fractions (Fr1-Fr3) from methanol extract was determined by high-performance liquid chromatography coupled with mass spectroscopy (HPLC-MS) analysis. RESULTS AND DISCUSSION The hexane extract was analyzed by GC-MS technique which allowed the identification of 32 compounds. The main constituents were α-humulene (16.9%), pentadecane (10.2%) and α-cubebene (9.7%). Fraction Fr 2 exhibited a strong DPPH radical-scavenging activity (IC50 = 20.1 μg/mL) compared to that of BHT as well as the highest α-amylase inhibitory activity (IC50 = 28.4 μg/mL). Three flavonoids were identified in these fractions using HPLC-MS analysis: Quercetin 3-O-glucoside, isoscutellarein 7-O-pentoside and quercetin 3-O-pentoside. In addition, the more active fraction (Fr 2) was purified with semi-preparative HPLC affording one pure compound (amentoflavone) using 1H NMR analysis. This compound exhibited powerful DPPH radical-scavenging (IC50 = 14.1 μg/mL) and α-amylase inhibition (IC50 = 20.4 μg/mL) effects. CONCLUSION This study provides scientific support to some medicinal uses of J. phoenicea found in North Africa.

Abstract
BACKGROUND The molluscicidal and larvicidal activities of the medicinal plant Citrullus colocynthis leaf extracts and its main cucurbitacins were tested against the mollusc gastropod Galba truncatula, the intermediate host of Fasciola hepatica. RESULTS Our findings proved for the first time that the molluscicidal activity was correlated with the presence of terpenoids. A significant molluscicidal value was found in the ethyl acetate extract (LC50 = 12.6 mg L-1 ). Further fractionation of this extract led to the isolation of two main compounds identified to cucurbitacin E 1 and 2-O-β-d-glucocucurbitacin E 2. Their molluscicidal activities were also investigated and they possessed close activities with LC50 = 9.55 and 10.61 mg L-1 for compounds 2 and 1, respectively. CONCLUSION The ethyl acetate extract and both pure compounds proved the highest larvicidal activities, with a deterioration rate exceeding 89.2% (89.2-100%) and with no toxic effects against associated fauna. © 2016 Society of Chemical Industry.

Abstract
IntroductionEpilepsy is a chronic disease defined as a brain disorder, characterized by a predisposition to present seizures, generating cognitive, psychological, and social consequences.ObjectiveTo determine the prevalence of psychiatric comorbid disorders in patients with epilepsy (PWEs) and its associated factors.MethodsWe conducted a cross-sectional study involving 30 PWEs who were treated in the neurology department of Habib Bourguiba Hospital in Sfax, Tunisia. We used the Mini International Neuropsychiatric Interview for the diagnosis of Axis I psychiatric disorders.ResultsThe half of patients had psychiatric comorbidities: 4 had major depressive disorder (MDD), 2 had MDD with generalized anxiety disorder, 4 had MDD with social phobia, 1 had bipolar disorder type I, 1 had panic disorder, 1 had agoraphobia and 2 had generalized anxiety disorder.Twenty-five PWEs had seizure-onset below 30 years old and among them, 40% had psychiatric comorbidities. Among patients who had seizure-onset above 30 years old, none had psychiatric comorbidities. Psychiatric comorbidities were found in 71.5% of patients with seizure frequency >2 per year. Psychiatric comorbidities were more common in patients with generalized seizures compared to whom with partial seizures (53% versus 45%). It was also more common in patients treated with polytherapy compared to whom with monotherapy (64% versus 37.5%).ConclusionThe prevalence of psychiatric comorbidities is relatively high among PWEs. The most frequent diagnoses found were mood and anxiety disorders. It is very important to identify them and treat them to enhance seizure control.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The aim of this study is to search new anti-obesity and anti-diabetic agents from plant and spices crude extracts as alternative to synthetic drugs. The inhibitory effect of 72 extracts was evaluated, in vitro, on lipase and amylase activities. Aqueous extracts of cinnamon and black tea exhibited an appreciable inhibitory effect on pancreatic amylase with IC50 values of 18 and 87 μg, respectively. Aqueous extracts of cinnamon and mint showed strong inhibitory effects against pancreatic lipase with IC50 of 45 and 62 μg, respectively. The presence of bile salts and colipase or an excess of interface failed to restore the lipase activity. Therefore, the inhibition of pancreatic lipase, by extracts of spices and plants, belongs to an irreversible inhibition. Crude extract of cinnamon showed the strongest anti-lipase and anti-amylase activities which offer a prospective therapeutic approach for the management of diabetes and obesity.

Abstract
Fasciolosis is a widespread parasitosis of farm live-stock in many developing
countries. For this reason, it is necessary to search for new substances against
parasitic diseases caused by flukes. Indeed, a wide variety of terrestrial plants
have been subjected to chemical and pharmacological screening in order to discover
their potential for human medicinal use. The molluscicidal and larvicidal activities
of Atriplex inflata were tested on Galba truncatula
and Fasciola hepatica larval stages infecting this snail in Tunisia.
Phytochemical tests were conducted on extracts in order to establish a meaningful
relationship with molluscicidal and larvicidal activities. The molluscicidal activity
was evaluated by subjecting snails to sample aqueous solutions. Accordingly, hexane,
ethyl acetate, methanol and methanol-water (8:2, v-v) were used as extraction
solvents. As a result, hexane and ethyl acetate extracts showed potent activity,
according to the World Health Organization, giving LC50 = 7.59 mg/L and
6.69 mg/L for hexane extracts of leaves and fruits, respectively. Ethyl acetate
extracts gave LC50 = 5.90 mg/L and 7.32 mg/L for leaves and fruits,
successively. Molluscicidal activities of powders were less potent on snails, but
active according to the World Health Organization. Hexane and ethyl acetate extracts
from leaves and fruits gave potent larvicidal activities with a delay rate exceeding
45.50% (45.50- 98.92%). Phytochemical tests showed that these activities may be
attributed to the presence of triterpenoids and/or sterols.

Abstract
The hexane extract of Echinops spinosissimus Turra subsp. spinosus flower heads was analyzed for its fatty acid and sterol composition. Its physicochemical characteristics were also studied. The saponification, iodine and peroxide values were determined as 255 mg KOH/g, 42.57 g I2 /100 g and 110 m equiv. O2 /kg of oil, respectively. The oleic (C18:1; 61.14%), palmitic (C16:0; 21.36%) and linoleic (C18:2; 10.45%) acids were the dominant fatty acids. This extract was also found to contain high levels of β-sitosterol and stigmasterol (44.97% and 34.95% of total sterols, respectively). On the other hand, the identification of terpenoid compounds was investigated by using GC/MS, which revealed fourteen major terpenoids mainly taraxasterol, lupeol, pseudotaraxasterol, lup-22(29)-en-3-yl acetate, taraxasteryl acetate, α-amyrin, β-amyrin, pseudotaraxasteryl acetate, hop-20(29)-en3-β-ol, α-amirenone, along with β-sitosterol and stigmasterol. Moreover, we have evaluated the in vitro antibacterial and antifungal activities of the unsaponifiable matter and a fraction isolated from this extract. These activities were conducted using the diffusion disc methods and broth microdilution assay. The resulted fraction from this extract showed the highest antibacterial activity with significant minimum inhibitory concentrations (MIC) values 125.0 μg/ml against Staphylococcus aureus, Micrococcus luteus and Bacillus cereus. However, it did exhibit no substantial antifungal activity.

Abstract
CONTEXT The persistence of fascioliasis in many developing countries urges the search for simple, cheap, and effective substances. In this view, plants provide interesting molluscicidal activities thanks to the secondary metabolites they produce. The genus Solanum is known for its potent effect on vector snails. OBJECTIVE The molluscicidal activity of Solanum elaeagnifolium Cav. (Solanaceae) seeds against Galba truncatula Müll. (Lymnaeidae), intermediate host of Fasciola hepatica L. (Fasciolidae), was evaluated. MATERIALS AND METHODS Solanum elaeagnifolium seeds were powdered and successively extracted using n-hexane, methylene chloride, acetone, and methanol, for 20 h each. After filtration, solvents were evaporated. An acid-base treatment was conducted on seed methanolic extract to isolate total alkaloids and β-solamarine. Total saponins fraction was obtained after successive macerations and evaporations. The molluscicidal activity was evaluated by subjecting snails, in groups of 10, for 48 h to 500 mL of extracts, fractions, and pure product aqueous solutions, each containing amounts, ranging from 1 to 50 mg of plant material in 5 mg increments. RESULTS The methanolic extract of seeds, β-solamarine isolated for the first time from this plant and total saponins fraction showed very potent activities on snails, giving respective median lethal concentrations (LC50) of 1.18, 0.49, and 0.94 mg/L. Total alkaloids fraction obtained from the methanolic extract was less active giving an LC50 value of 14.67 mg/L. DISCUSSION AND CONCLUSION This study emphasizes that glycoalkaloids and saponins of Solanum elaeagnifolium are potent molluscicidal agents. Seed methanolic extract, β-solamarine, and total saponins fraction may be used as molluscicides.

Abstract
In this study, we investigated the protective effects of Peganum harmala seeds extract (CPH) against chronic ethanol treatment. Hepatotoxicity was induced in male Wistar rats by administrating ethanol 35% (4 g/kg/day) for 6 weeks. CPH was co-administered with ethanol, by intraperitonial (IP) injection, at a dose of 10 mg/kg bw/day. Control rats were injected by saline solution (NaCl 9‰). Chronic ethanol administration intensified lipid peroxidation monitored by an increase of TBARS level in liver. Ethanol treatment caused also a drastic alteration in antioxidant defence system; hepatic superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities. A co-administration of CPH during ethanol treatment inhibited lipid peroxidation and improved antioxidants activities. However, treatment with P. harmala extract protects efficiently the hepatic function of alcoholic rats by the considerable decrease of aminotransferase contents in serum of ethanol-treated rats.

Abstract
Diabetes mellitus is a serious health problem worldwide that has adverse and long-lasting consequences for individuals, families, and communities. Hence, this study sought to investigate the inhibitory potential of rosemary extracts on key-enzymes related to diabetes such as α-amylase and pancreatic lipase activities, as well as to assess their antioxidant properties in vitro. The IC50 values of Rosemary essential oil, ethyl acetate and methanolic extracts against α-amylase were 28.36, 34.11 and 30.39 µg/mL respectively, and those against pancreatic lipase were 32.25, 36.64 and 34.07 µg/mL, suggesting strong anti-diabetic and anti-obesity effects of Rosemary. The methanolic extract was found to be the highest in levels of phenolic (282.98 µgGAE/mg extract) and flavonoids (161.05 µg QE /mg extract) contents as well as in the antioxidant activity (IC50 = 15.82 µg/mL) as compared to other extracts ethyl acetate (IC50 = 32.23 µg/mL) and essential oil (IC50 = 96.12 µg/mL).Antioxidant efficacy of Rosemary extracts has been estimated in the stabilization of sunflower oil (SFO) at three different concentrations, i.e. 200 (SFO-200), 500 (SFO-500) and 1000 ppm (SFO-1000). Results showed the highest efficiency of SFO-1000.The results obtained in this study demonstrated for the first time that Rosemary is a potent source of natural inhibitors of α-amylase and pancreatic lipase with powerful antioxidants proprieties that might be used in the food stabilization and the prevention of diabetes and obesity complications as a complementary pharmacological drug.
