Three model arginine-rich tripeptides RXR (X = W, F or non-natural residue 2-napthylalanine) were investigated as antimicrobial agents, with a specific focus to target Pseudomonas aeruginosa through membrane lysis. Activity against biofilms was related to binding of the second messenger molecule, nucleotide bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP). Strong selective activity against P. aeruginosa in planktonic form was observed for RFR and RWR.

The study of chalcone-1,2,3-triazole hybrids for anticancer activity is quite a recent area of focus, primarily because of the increasing demand for developing new drugs to treat cancer. The chalcones and 1,2,3-triazole rings in hybrid compounds has recently emerged as a promising strategy for developing novel anticancer agents. The 1,2,3-triazole ring, known for its stability and hydrogen bonding capabilities, enhances the target binding affinity of these hybrids.

Aim: Thyroid nodules, based on high-resolution ultrasonography (HRUS), are among the most common endocrine abnormalities that affect the general population because of their high estimated prevalence rates. Fine needle aspiration cytology (FNAC) is a safe, cost-effective modality to differentiate between benign and malignant thyroid nodules based on the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), thus avoiding unnecessary surgery. However, categories III and IV of BSRTC remain a controversial issue in clinical practice, encompassing a wide range of risks of malignancy.

Purpose: Postoperative thirst is common and distressing to patients, as is pain and nausea. The causes of postoperative thirst are complex and include factors like preoperative fasting, perioperative fluid loss, and certain anesthesia medications. Effective care for postoperative thirst has been shown in post-anesthesia care units (PACUs), but many Japanese hospitals lack PACUs or do not address thirst in their PACUs.
