Abstract

For the first time in Libyan flora, a new record for Boerhavia repens L is recorded. This widespread wild weed was collected from the Ariggiba region (110 km west-south Sabha city). A full description, habitat information, distribution map, and distribution data are provided to facilitate further identification and future detection. A brief discussion about the most important threats this species poses is presented.

Abstract Background:- Depakine (valproic acid) is an antiepileptic medication that is commonly used as a first‑line treatment for a variety of seizures in both adults and children. However, it can result in testicular toxicity by increasing oxida tive stress inflammation. Melatonin (MLT) has antioxidant, anti‑inflammatory, and anti‑apoptotic potential. Therefore, the present study investigated the impact of MLT on depakine‑induced testicular damage in rats.

Abstract

The aim of this study was to investigate the prevalence, causes of tooth loss, and associated factors among the older adult population attending dental clinics in the city of Gharyan in Libya. A descriptive cross-sectional study conducted among adults who came to private clinics in the city of Gharyan in Libya. There were 160 patients participated in the study. Those that met the inclusion criteria had their data collected via self-administered questionnaires. Computer-assisted techniques used to examine the data (IPMSPSS). The results of the present study indicated that the major cause of tooth loss was dental caries (65.56%), followed by periodontal disease (11.88%). and more teeth loss was in the female than male and increased tooth loss with aging. In conclusion, there was a high prevalence of tooth loss. Females lost more teeth than males. Increased proportion of tooth loss seen in the elderly population.

كان الهدف من هذه الدراسة هو التحقيق في انتشار وأسباب فقدان الأسنان والعوامل المرتبطة بها بين كبار السن الذين يرتادون عيادات الأسنان في مدينة غريان في ليبيا. أجريت دراسة وصفية مقطعية بين البالغين الذين جاءوا إلى العيادات الخاصة في مدينة غريان في ليبيا. شارك في الدراسة 160 مريضًا. تم جمع بيانات أولئك الذين استوفوا معايير الإدراج من خلال استبيانات ذاتية الإدارة. تم استخدام تقنيات بمساعدة الكمبيوتر لفحص البيانات (IPMSPSS). أشارت نتائج الدراسة الحالية إلى أن السبب الرئيسي لفقدان الأسنان كان تسوس الأسنان (65.56٪)، يليه مرض اللثة (11.88٪). وكان فقدان الأسنان أكثر لدى الإناث منه لدى الذكور وزيادة فقدان الأسنان مع تقدم العمر. في الختام، كان هناك انتشار كبير لفقدان الأسنان. فقدت الإناث أسنانًا أكثر من الذكور. زادت نسبة فقدان الأسنان لدى كبار السن

Synthesizing silver nanoparticles (AgNPs) from extracts of various plant parts

and of agricultural waste is strongly affected by pH. These green synthesis

methods cconsidered simple, cost effective, ecofriendly, and biologically

effective. This brief review aimed to survey the role of pH in the green

synthesis of AgNPs using those media, with a focus on its effect on AgNPs

morphology and size. This review article revealed that the alkaline pH (9 -

10) is the optimum condition for synthesizing more stable and tiny uniform

AgNPs. In addition, according to the reviewed articles, the spherical shape is

the most dominant shape of these articles in the basic medium and the size of

these particles decreases at elevated pH values and ranged from 5-40 nm
