How genetic variation contributes to adaptation at different environments is a central focus in evolutionary biology. However, most free-living species still lack a comprehensive understanding of the primary molecular mechanisms of adaptation. Here, we characterised the targets of selection associated with drastically different aquatic environments-humic and clear water-in the common freshwater fish, Eurasian perch (Perca fluviatilis).

Background: Long-gap esophageal atresia (LGEA) can complicate the management of esophageal atresia (EA) with or without a tracheoesophageal fistula (TEF). This series describes a short interval, staged, thoracoscopic internal traction approach for LGEA with distal TEF to manage complex anastomotic tension or an anatomically impossible esophageal anastomosis.

Methods: A retrospective review (2018-2024) was performed across four tertiary centers to identify patients with LGEA and distal TEF, managed with a staged, thoracoscopic internal traction approach.

The established dogma about regulation of feeding is based on the interaction amongst hypothalamic orexigenic and anorexigenic neuropeptides. However, the molecular underpinnings of those interactions remain unclear. A recent article published in by first demonstrated that the transition between hunger and satiety depends on the regulation of 3',5'-cyclic adenosine monophosphate (cAMP) in the paraventricular nucleus of the hypothalamus (PVH) providing novel insights on the spatial and temporal basis by which neuropeptides act.

The COVID-19 Pandemic increased the prevalence and severity of insomnia and depression symptoms. The effects of an insomnia intervention on future insomnia and depression symptoms delivered during an ongoing stressor, which may have precipitated the insomnia symptoms, is unknown. We conducted a two-arm randomized controlled pilot study to evaluate whether an insomnia intervention would improve the trajectory of insomnia and depression symptoms in the context of a global pandemic.

Fournier's gangrene (FG) is a type of necrotizing fasciitis affecting the abdomen or perineum. It is a polymicrobial infection that progresses to an obliterating endarteritis, causing thrombosis and subsequent tissue necrosis, allowing pathogenic invasion of interfacial planes.Patients with Fournier's gangrene typically have underlying systemic conditions that cause vascular insufficiencies or immunosuppression.
