Bioactive natural compounds, isolated from fungal endophytes, play a promising role in the search for novel drugs. They are an inspiring source for researchers due to their enormous structural diversity and complexity. During the present study fungal endophytes were isolated from a well-known medicinal shrub, Berberis aristata DC. and were explored for their antagonistic and antioxidant potential. B. aristata, an important medicinal shrub with remarkable pharmacological properties, is native to Northern Himalayan region. A total of 131 endophytic fungal isolates belonging to eighteen species and nine genera were obtained from three hundred and thirty surface sterilized segments of different tissues of B. aristata. The isolated fungi were classified on the basis of morphological and molecular analysis. Diversity and species richness was found to be higher in leaf tissues as compared to root and stem. Antibacterial activity demonstrated that the crude ethyl acetate extract of 80% isolates exhibited significant results against one or more bacterial pathogens. Ethyl acetate extract of Alternaria macrospora was found to have potential antibacterial activity. Significant antioxidant activity was also found in crude ethyl acetate extracts of Alternaria alternata and Aspergillus flavus. Similarly, antagonistic activity of the fungal endophytes revealed that all antagonists possessed inhibition potential against more than one fungal pathogen. This study is an important step towards tapping endophytic fungal diversity for bioactive metabolites which could be a step forward towards development of novel therapeutic agents.

Radiotherapy plays a major role in the treatment of cervical cancer. A successful radiotherapy program integrates both external beam and brachytherapy components. The principles of radiotherapy are strongly based on the anatomy of the organ and patterns of local and nodal spread. However, in patients with distorted anatomy, several practical issues arise in the delivery of optimal radiotherapy, especially with brachytherapy. Müllerian duct anomalies result in congenital malformations of the female genital tract. Though being very commonly studied for their deleterious effects on fertility and pregnancy, they have not been recognized for their potential to interfere with the delivery of radiotherapy among patients with cervical cancer. Here, we discuss the management of cervical cancer among patients with Müllerian duct anomalies and review the very sparse amount of published literature on this topic.
