A resurgence of interest in the pathways that bacteria use to protect against their viruses (i.e. phages) has led to the discovery of dozens of new antiphage defenses. Given the sheer abundance and diversity of phages - the ever-evolving targets of immunity - it is not surprising that these newly described defenses are also remarkably diverse. However, as their mechanisms slowly come into focus, some common strategies and themes are also beginning to emerge. This review highlights recurring and emerging themes in the mechanisms of innate immunity in bacteria and archaea, with an emphasis on recently described systems that have undergone more thorough mechanistic characterization.

Mammalian sterile20-like kinase 1 (MST1), a serine/threonine kinase frequently expressed, has emerged as pivotal modulator of multiple physiological and pathological conditions such as cellular growth, programmed cell death, oxidative stress, neurodegeneration, inflammation, and synaptic plasticity in the central nervous system. Various neurological diseases are associated with the activation of MST1. Epilepsy is a severe neurological disorder characterized by abrupt abnormal electrical activity in the brain and recurring spontaneous seizures.

Wild birds are important hosts of influenza A viruses (IAVs) and play an important role in their ecology. The emergence of the A/goose/Guangdong/1/1996 H5N1 (Gs/GD) lineage marked a shift in IAV ecology, leading to recurrent outbreaks and mortality in wild birds from 2002 onwards. This lineage has evolved and diversified over time, with a recent important derivative being the 2.

Background: In South Kivu (Eastern Democratic Republic of the Congo [DRC]), health districts (HDs) affected by chronic armed conflicts are devising coping mechanisms to continue offering healthcare services to the population. Nonetheless, this alone does not suffice to make them fully resilient to such conflicts. This study aims to explore the characteristics of these HDs' resilience.

This study reports the first case of THPP in an adolescent with type 1 diabetes mellitus (T1DM) and Graves' disease, triggered by high-dose insulin, high carbohydrate intake, and strenuous exercise. It highlights the clinical presentation, management, and implications of THPP in this context.

Gallstone ileus is the mechanical obstruction of the bowel due to gallstone impaction. It forms when a fistula is created between the gallbladder and the gastrointestinal tract, which can result in small bowel obstruction. Its surgical management ranges from enterolithotomy, cholecystectomy, and fistula closure performed together (one-stage) or performed separately (two-stage), while some patients undergo simple enterolithotomy.
