Phoenix dactylifera L. (Date palm) is the most widely consumed fruit around the world and is rich source of nutrients containing dietary fibers, minerals, vitamins, sugar, protein and antioxidants with potent bioactivities against various microbial pathogens. This study evaluated the therapeutic potential of 2 varieties of ethanolic extracts of Phoenix dactylifera i-e Ajwa and Khalas against bacterial biofilms. This study also investigated the protective effect of Ajwa and Khalas against hydroxyl radical damage to calf thymus DNA. Antioxidant potential through different antioxidant assays showed that Ajwa has higher antioxidant potential than Khalas. Both Ajwa and Khalas presented good antimicrobial activities against Bacillus subtilis and Pasteurella multocida. Biofilm inhibition assay showed that increasing concentration of Ajwa and Khalas exhibited higher percentage of bacterial biofilm inhibition. Microscopic examination revealed significant inhibition of microbial biofilm. Ajwa and Khalas protected the calf thymus DNA against damage caused by hydroxyl radicals produced by fenton reagent. Fourier Transform Infrared (FTIR) spectra confirmed the presence of O–H, C=C and C–O functional groups in tested extracts. The study concluded that tested varieties of Date palm have the potential to inhibit bacterial biofilms and can be used for therapeutic purposes against biofilm producing pathogens.
Dengue fever is the most significant arthropod-transmitted viral disease in terms of mortality and morbidity, affecting at least 50 million people around the world. It is commonly recognized as "breakbone" fever as it is mostly associated with severe muscle and joint pain. The objective of the study was to evaluate and assess the levels of selected vitamins and hormones in serum of dengue patients from Faisalabad, Pakistan. Estimation of serum levels of vitamins D 3 and K was carried out through spectrophotometer, while concentration of serum hormones, angiotensinogen and thrombopoietin, was determined through enzyme-linked immunosorbent assay (ELISA) kit method. Hematological blood parameters were also investigated. Hematological parameters significantly (P < 0.05) differ in dengue fever patients and normal control subjects. Vitamin D 3 level was found significantly (P < 0.05) decreased in test group (dengue patients) compared to control group (healthy individual). Vitamin K level was also reduced in test group compared to control group, but this reduction was nonsignificant (P > 0.05). Among the tested hormones, angiotensinogen level was found significantly (P < 0.05) lower in test group, while thrombopoietin was nonsignificantly (P > 0.05) higher compared to control group. In conclusion, the results of the current study demonstrated the significance of tested vitamins and hormones along with blood parameters in monitoring the dengue infected patients.
Background: Phytomedicine is becoming more acceptable as an alternative medicinal approach in the modern era. Objectives: The current study examined the antioxidant capacity and in vitro response of phytochemical constituents of Withania somnifera (Ashwagandha) on standard parameters of healthy volunteer semen. Methods: The phytochemicals and their pharmacological response in a hydroethanolic (30:70 v/v) extract of W. somnifera roots were determined using standard protocols. Results: The constituents included flavonoids, phenolic acids, alkaloids, and terpenoids were reported. High-performance liquid chromatography and Fourier-transform infrared spectroscopy determined a diverse array of biologically active chemical constituents in the extract. The extract of W. somnifera exhibits substantial antioxidant properties, including total antioxidant capacity, 2,2-diphenyl-1-picrylhydrazyl inhibition, H2O2 scavenging, and Fe3+ reducing potential ( P < .05). The analysis of essential natural minerals explored adequate levels determined using atomic absorption spectrophotometer. Cytotoxic studies revealed significant thrombolytic, RBC membrane stabilization, and DNA damage protection activity ( P < .05) while remaining non-mutagenic against Salmonella typhi TA98 and TA100. The best protective response of W. somnifera extract on human semen parameters (n = 30), such as total motility, progressive motility, and viability, demonstrated a significant ( P < .05) improvement, particularly at the dose of 25 μg/mL and 50 μg/mL. Conclusion: The study concludes that W. somnifera possesses favorable in vitro characteristics that could aid in the preservation of sperm during intrauterine insemination and in vitro fertilization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
