Operative strategies and outcomes for patients with severe pulmonary artery hypertension and intestinal obstruction: case series from single institution-sharing lessons to improve surgical outcomes.

Pulmonary hypertension is a known perioperative risk factor that carries a high morbidity and mortality rate. Severe pulmonary hypertension is related to high morbidity after general anaesthesia. We are reporting three patients with underlying severe pulmonary hypertension, who presented with intestinal obstruction managed with different perioperative approaches.

Molecular circadian rhythms are robust in marine annelids lacking rhythmic behavior.

The circadian clock controls behavior and metabolism in various organisms. However, the exact timing and strength of rhythmic phenotypes can vary significantly between individuals of the same species. This is highly relevant for rhythmically complex marine environments where organismal rhythmic diversity likely permits the occupation of different microenvironments.

All Light, Everywhere? Photoreceptors at Nonconventional Sites.

One of the biggest environmental alterations we have made to our species is the change in the exposure to light. During the day, we typically sit behind glass windows illuminated by artificial light that is >400 times dimmer and has a very different spectrum than natural daylight. On the opposite end are the nights that are now lit up by several orders of magnitude.

Glucagon-like peptide-1 therapy in people with obesity restores natural killer cell metabolism and effector function.

Objective: People with obesity (PWO) have functionally defective natural killer (NK) cells, with a decreased capacity to produce cytokines and kill target cells, underpinned by defective cellular metabolism. It is plausible that the changes in peripheral NK cell activity are contributing to the multimorbidity in PWO, which includes an increased risk of cancer. This study investigated whether therapy with long-acting glucagon-like peptide-1 (GLP-1) analogues, which are an effective treatment for obesity, could restore NK cell functionality in PWO.

The Interrelation between Oxidative Stress, Depression and Inflammation through the Kynurenine Pathway.

The prevalence of depression has increased dramatically over the past few decades. Although depression is categorized as a brain disorder, its symptomatology includes some behaviors that also occur during chronic inflammatory stress. According to research, cytokine production and immune system activation may have a role in depression, so this relationship has received much attention.
