سابقه و هدف: ژل های in situ به عنوان سیستم های دارورسانی برای کنترل رهش دارو و محافظت درمانی به صورت موفقیت آمیز استفاده شده اند. هدف از این مطالعه تهیه و ارزیابی ژل های موضعی دهانی in situ از فلوکونازول بر اساس سیستم تغییر ph می باشد. مواد و روش ها: فرمولاسیون های مختلف بر اساس سیستم تغییر ph حاوی کربوپل 934، همراه با هیدروکسی پروپیل متیل سلولز و سدیم آلژینات برای طولانی کردن رهش فلوکونازول ته...
Conservation breeding programmes have become an increasingly important tool to save endangered species, yet despite the allocation of significant resources, efforts to create self-sustaining populations have met with limited success. The iconic giant panda (Ailuropoda melanoleuca) embodies the struggles associated with ex situ species conservation. Here we show that behavioural mate preferences...
The loss of plant genetic resources has made necessary the development of new ex situ conservation methods. Advances in biotechnology provide new methods for plant germplasm conservation and evaluation. Biotechnological tools like in vitro culture, cryopreservation, and molecular markers offer a valuable alternative to plant diversity studies, management of genetic resources and ultimately cons...
The challenges to execute wildlife conservation projects successfully have become more complex as anthropogenic changes continue to stress the planet, changing wild lands. As the wild becomes less so, more species are placed in captivity to improve their chances of long-term survival, while concurrently management (and medicine) for free-ranging wildlife has become increasingly important. A var...
Crop wild relatives have a long history of use in potato breeding, particularly for pest and disease resistance, and are expected to be increasingly used in the search for tolerance to biotic and abiotic stresses. Their current and future use in crop improvement depends on their availability in ex situ germplasm collections. As these plants are impacted in the wild by habitat destruction and cl...
BACKGROUND Breast-conservation surgery with radiotherapy is a treatment highly recommended by the guidelines from the National Comprehensive Cancer Network. However, several variables influence the final receipt of radiotherapy and it might not be administered to breast cancer patients. Our objective is to propose a systematic framework to identify the clinical and non-clinical variables that i...
