Survival, recurrence, and xerostomia are considerable problems in the treatment of oral squamous carcinoma patients. In this study, we investigated the role of DMA (5-(4-methylpiperazin-1-yl)-2-[2'-(3,4-dimethoxyphenyl)5″benzimidazoyl]benzimidazole) as a salivary gland cytoprotectant in a patient-derived xenograft mouse model. A significant increase in saliva secretion was observed in the DMA-treated xenograft compared to radiation alone.

Salicylic acid phenylethyl ester (SAPE) was synthesized by Zn(OTf)-catalyzed selective esterification of salicylic acid and phenylethyl alcohol and studied for its role as an immunomodulatory and anticancer agent. Low toxicity and favorable physical, Lipinski-type, and solubility properties were elucidated by ADME-tox studies. Molecular docking of SAPE against COX-2 revealed favorable MolDockscore, rerank score, interaction energy, internal pose energy, and hydrogen bonding as compared to ibuprofen and indomethacin.

With the advancement of nanotechnology, the nano-sized particles make an imprint on our daily lives.The present investigation revealed that biomolecules present in seed exudates of Vigna radiata are responsible for the synthesis of AuNPs, confirmed by the routine characterization techniques. Anticancer efficacy showed by AuNPs might be due to the release of phytochemicals in the exudate which is being adsorbed on the surface of AuNPs referencing their anticancer efficacy against the tested breast cancer cell lines.

Zinc oxide nanoparticles (ZNP) are being used in various fields viz cosmetics industry as UV protectants, in the food packaging industry due to their anti-bacterial properties, in agriculture as micronutrients, etc. Increased applications of ZNPs in our day to day life, leading to the contamination of the surrounding environment posing a direct or indirect health risk. Various reports suggest that fruits and vegetables are a rich source of phytochemicals having antioxidant properties which help in neutralizing ROS generated on metal toxicity of the body.

Nanoparticles are being used extensively and found in applications to various fields ranging from agriculture to electronic devices, diagnosis to drug delivery, and cosmetics to food packaging. Increasing usage of engineered nanomaterials (ENM) raises potential concern for human health as well as to the environment. The present study aims to explore the effects of intermittent intraperitoneal exposure of ZNP on the spleen of male Wistar rat.

Protein degradation and turnover under various environmental stresses is basically regulated by ubiquitin-proteasome system (UPS), of which SKP1 is a very essential component. Isolation and cloning of an identified potential stress responsive candidate gene SKP1, was successfully done for the first time to fathom the role of SKP1 in drought tolerance at genetic level in drought tolerant mungbean cultivar Pratap, which was screened after a detailed physio-biochemical screening amongst seven popular mungbean cultivars. The cloned gene SKP1 (accession number KX881912) is 550 bp in length, encodes 114 amino acids.
