SPAD dynamics in maize crop with precision nitrogen management under rain-fed and irrigated conditions.

Real-time monitoring of canopy chlorophyll content is crucial for understanding crop growth and guiding precision agricultural management. The SPAD chlorophyll meter is a valuable tool for assessing nitrogen status in maize (Zea mays L.), a key cereal crop used for food, feed, and biofuels.

Transumbilical Laparoscopic-Assisted Appendectomy (TULAA): A Fast, Safe, and Scarless Alternative to Conventional Three-Port Laparoscopic Appendectomy in Pediatric Patients.

Introduction: Acute appendicitis is a common pediatric surgical emergency requiring timely intervention. Conventional three-port laparoscopic appendectomy (CLA) is widely used, offering reduced postoperative pain, faster recovery, and lower wound infection rates. The transumbilical laparoscopic-assisted appendectomy (TULAA) technique, a single-incision approach, promises improved cosmetic outcomes, shorter operative time, and reduced morbidity.

Discovery of new inhibitors of nuclease MRE11.

MRE11 nuclease is a central player in signaling and processing DNA damage, and in resolving stalled replication forks. Here, we describe the identification and characterization of new MRE11 inhibitors MU147 and MU1409. Both compounds inhibit MRE11 nuclease more specifically and effectively than the relatively weak state-of-the-art inhibitor mirin.

Castleman's Disease Presenting as an Unusual Pelvic Retroperitoneal Mass.

Castleman's disease (CD) is characterised by benign lymphoepithelial proliferation and is a peculiar form of angiofollicular lymph node hyperplasia rather than a neoplasm or a hamartoma. CD is broadly classified as unicentric CD (UCD) and multicentric CD. In the unicentric variant, patients have localised disease affecting only a single lymph node or a group of adjacent nodes in a single region, which clinically presents as an enlarging mass without any other significant symptoms.

Prins cyclization: new strategy for the stereoselective total synthesis of Polyrhacitide A.

A highly stereoselective total synthesis of polyrhacitide A, a polyketide natural product, has been accomplished by means of Prins cyclisation. The key precursor i.e.
