Analysis on Salinity Tolerance of Lettuce Cultivars Under Saline Irrigation and Application of Organic Acids.

Freshwater depletion becomes a significant challenge as the population grows and food demand rises. We evaluated the responses of lettuce cultivars () under saline stress in photosynthetic responses, production, and ion homeostasis. We used a randomized block design in a 3 × 5 factorial scheme with five replications-the first factor: three cultivars of curly lettuce: SVR 2005, Simpson, and Grand Rapids.

Advances and current concepts on Eph receptors and ephrins in upper digestive tract cancers.

Erythropoietin-producing hepatocellular (Eph) receptors comprise the largest group of surface receptors and are responsible for cellular signals. Eph/ephrin signaling has been identified to play a role in key cancer development and progression processes, especially in the upper gastrointestinal tract. The Eph/ephrin system has been described as a tumor suppressor in duodenal cancer, while in esophageal, gastric, hepatic, and pancreatic cancer, the system has been related to tumor progression.

Adjustable wind selectivity in shearwaters implies knowledge of the foraging landscape.

Understanding the movements of highly mobile animals is challenging because of the many factors they must consider in their decision-making. Many seabirds, for example, are adapted to use winds to travel long distances at low energetic cost but also potentially benefit from targeting specific foraging hotspots. To investigate how an animal makes foraging decisions, given the inevitable trade-off between these factors, we tracked over 600 foraging trips of breeding Manx shearwaters (Puffinus puffinus; N = 218 individuals) using GPS accelerometers.

Outcomes of segmentectomy versus lobectomy in adults with non-cystic fibrosis bronchiectasis.

Objective: Surgical resection remains the gold standard treatment for bronchiectasis in patients who present with hemoptysis or suppuration, as well as in those who do not respond to clinical treatment. We sought to investigate the efficacy of sublobar resection (segmentectomy) and compare it with that of lobar resection (lobectomy) in patients with non-cystic fibrosis bronchiectasis.

Methods: Patients undergoing lobectomy or segmentectomy between 2019 and 2023 were included in the study.

Elucidating on the Quaternary Structure of Viper Venom Phospholipase A Enzymes in Aqueous Solution.

This study focuses on the quaternary structure of the viper-secreted phospholipase A (PLA), a central toxin in viper envenomation. PLA enzymes catalyse the hydrolysis of the sn-2 ester bond of membrane phospholipids. Small-molecule inhibitors that act as snakebite antidotes, such as varespladib, are currently in clinical trials.
