Response of Male Reproductive System Against Ionizing Radiation and Available Radio-protective Agents: Cellular and Molecular Insight.

Background: The reproductive organ, housing spermatogonial stem cells (SSCs), undergoes ongoing division impacted by the irradiation dosage and exposure duration. Within the male reproductive organ, germ stem cells (spermatogonia) and somatic cells (Sertoli and Leydig cells) are present. Lower doses of ionizing (>4-6 Gy) and non-ionizing radiation (radiofrequency and microwave range 900 MHz - 2.

Exploring the Synthetic and Antioxidant Potential of 1,2-Disubstituted Benzimidazoles Using [EtNH][HSO] Ionic Liquid Catalyst.

An [EtNH][HSO] ionic-liquid catalyzed, intermolecular C-N bond formation for 1,2-disubstituted benzimidazole synthesis was achieved by the reaction of OPD and substituted aldehydes at ambient reaction conditions. Operational simplicity, use of easily available substrate and reagents, good yields (74-95 %) in short reaction time (4-18 min), simple work-up, and column chromatographic free synthesis are the remarkable features of this new protocol. The applicability of [EtNH][HSO] ionic-liquid as a green and inexpensive catalyst with good recyclability and compatibility with a broad range of functional group having heteroatom, electron-withdrawing, and electron-releasing groups manifested the sustainability, eco-friendliness, and efficiency of the present methodology.

Modulation of radiation-induced intestinal injury by radioprotective agents: a cellular and molecular perspectives.

The gastrointestinal (GI) system has rapidly proliferating and differentiating cells, which make it one of the most radiosensitive organs in the body. Exposure to high dose of ionising radiation (IR) during radiotherapy may generate a variety of reactive oxygen species (ROS) and reactive nitrogen species (RNS) including radicals, cause some side effects such as nausea, vomiting, diarrhoea, pain, ulceration, mal-absorption etc. Irradiation disrupts GI system by damaging proliferating stem cells of the crypts that alters the histology and physiology of intestine.
