On the basis of the study of 2388 patients with chronic gastric and duodenal ulcers complicated by acute bleeding, the most disputable organizational and tactical issues of ulcer bleeding (UB) treatment are discussed. It is reasonable to divide surgery for UB into urgent, delayed and elective. Indications for different surgeries in UB and basic surgical principles are discussed. Severe blood loss is the main factor of general lethality. Combined conservative therapy must provide correction of posthemorrhagic tissue hypoxia, functional disorders, hemostatic disturbances and immunosuppression. Artificial transmitters of oxygen and infusion of antihypoxants are promising in management of UB. Antisecretory drugs are a necessary component of conservative treatment in UB. Therapeutic endoscopy is important in the treatment of acute UB, but it is not alternative to surgical hemostasis. It may be regarded as a method of temporary hemostasis before delayed for more than 2 hours operation or as a method of final hemostasis in combined conservative treatment, first of all in patients of "surgical risk" group.

Influenced by urban expansion, population growth, and various socio-economic activities, land use in the Yangtze River Delta (YRD) area has undergone prominent changes. Modifications in land use have resulted in adjustments to ecological structures, leading to subsequent fluctuations in carbon storage. This study focuses on YRD region and analyzes the characteristics of land use changes in the area using land use data from 2000 to 2020, with a 10-year interval.

Trade in wood and forest products spans the global supply chain. Illegal logging and associated trade in forest products present a persistent threat to vulnerable ecosystems and communities. Illegal timber trade has been linked to violations of tax and conservation laws, as well as broader transnational crimes.

Hepatitis C Virus (HCV) is a blood borne pathogen that affects around 200 million individuals worldwide. Immunizations against the Hepatitis C Virus are intended to enhance T-cell responses and have been identified as a crucial component of successful antiviral therapy. Nevertheless, attempts to mediate clinically relevant anti-HCV activity in people have mainly failed, despite the vaccines present satisfactory progress.

The nematode C. elegans has long served as a gold-standard model organism in aging research, particularly since the discovery of long-lived mutants in conserved aging pathways including daf-2 (IGF1) and age-1 (PI3K). Its short lifespan and small size make it highly suitable for high-throughput experiments.

Understanding insect behaviour and its underlying drivers is vital for interpreting changes in local biodiversity and predicting future trends. Conventional insect traps are typically limited to assess the composition of local insect communities over longer time periods and provide only limited insights into the effects of abiotic factors, such as light on species activity. Achieving finer temporal resolution is labour-intensive or only possible under laboratory conditions.
