    Infertility is a multifaceted issue, involving male and female factors, along with modifiable and non-modifiable elements. Our investigation delved into the effects of daily peanut and Jujubier wild honey consumption on reproductive function and heightened seminal secretions in 21-day-old male hamsters (n=12), divided into three groups. By scrutinizing gonad, seminal vesicle size, and body weight, we observed positive influences of diets containing peanut and/or honey, notably on body weight and testis size in comparison to control groups. This preliminary study underscores the potential impact of diet on sperm production in prepubescent male hamsters, offering early insights into dietary strategies for potentially addressing infertility. As a topical concern, infertility's intricate dynamics warrant further exploration, and our study contributes to the growing understanding of the interplay between diet and reproductive health

    HPLC-DAD/TOF-MS Chemical Compounds Analysis and Evaluation of Antibacterial Activity of Aristolochia longa Root Extracts

    The present study aimed to determine the phenolic compounds of Arislolochia Ion& root extracts and to evaluate their antibacterial activities on multiresistant strains. Phytochemical analysis revealed the presence of flavonoids, tannins, terpenoids, and alkaloids. The HPLC-DAD analysis of A. longa extracts showed the presence of several major bioactive compounds such as ferulic acid, 4-hydroxycinnamic acid, citric acid, and quinic acid. The agar diffusion method was used for the sensitivity test, while minimal inhibitory concentration (MIC) and minimal bactericidal concentration values were determined by microdilution assay. Different tests were carried out on 3 clinical multiresistant strains and 3 reference strains. The diameter of inhibition of Staphylococcus aureus ATCC 25923 induced by the ethyl acetate fraction at 200 mg/mL was 25 +/- 1 mm. Moreover, Escherichia coli ATCC 29522 showed a great sensitivity toward all the concentrations tested. The MICs of the active extracts vary between 12.5 and 100 mg/mL with a bacteriostatic effect on Pseudomonas aemginosa ATCC 27853, Enterococcus faecalis, and S. aureus ATCC 25923.Peer reviewe

    Purpose. The aim of this study is to investigate the possible role of heavy metals (lead and cadmium) and imbalance of trace elements (chromium, iron, zinc, copper, and manganese) in death among patients with severe traumatic brain injury. Material and Methods. A case-control study was conducted with 64 comatose patients with severe TBI, in the Department of Anesthesiology and Reanimation, Ibn Sina University Hospital and Hospital of Specialties in Rabat, Morocco; 22 healthy volunteers were recruited in Blood Transfusion Center of Rabat. Blood samples were collected from TBI patients, in the first week (3h after admission and each 48h during one week) and from healthy volunteers one time. Concentration of heavy metals and trace elements in serum was determined by electrochemical atomic absorption spectrometry. Statistical analysis was performed using Statistical software (SPSS) and the cases and controls were compared using the Mann–Whitney U test and Student’s t-test for cadmium according to gender and final evolution. A P-value <0.05 was considered to be statistically significant. Results. Our data showed that the difference of heavy metals concentration (lead and cadmium) between patients and healthy subjects was not statistically significant. However, the difference of some trace elements concentration (iron, copper, chromium, and selenium) between patients and healthy subjects was statistically significant. According to the final evolution, the concentration of manganese was higher in dead patients and statistically significant (p = 0.04) for heavy metals; the concentration of lead was not statistically significant while the concentration in cadmium was statistically significant (p = 0.004). By sex, lead and cadmium were statistically significant, respectively p = 0.02, p = 0.001, and cadmium was higher in women, while lead was higher in men. Conclusion. Among all studied heavy metals (lead and cadmium) and trace elements (iron, zinc, copper, selenium, chromium, and manganese), manganese and cadmium may play a role in the death of patients from severe traumatic brain injury

    Oxidative stress plays a major role in diabetic physiopathology; hence, the interest of using natural antioxidants as therapeutic tools exists. The aim of this study was the evaluation of in vitro antioxidant activity and inhibitory potential of organic extracts from Aristolochia longa roots against key enzymes linked to hyperglycemia. Antioxidant activity was performed using 2,2′-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals and ferric reducing/antioxidant power (FRAP) methods. The α-Glucosidase and β-Galactosidase inhibitory activities were investigated using an in vitro model. Moreover, phytochemical analysis of tested extracts was carried out. The aqueous fraction of this herb exhibited the highest antioxidant activity for both DPPH and ABTS methods, IC50=125.40±2.40 μg/mL and IC50=65.23±2.49 μg/mL, respectively. However, the ethyl acetate fraction possessed the strongest inhibitory effect towards α-Glucosidase (IC50=1.112±0.026 mg/mL). Furthermore, the result showed high levels of phenolic content. The results showed that this plant could be a significant source of medically important natural compounds
