The Effect of Milk-Derived Extracellular Vesicles on Intestinal Epithelial Cell Proliferation.

Inflammatory bowel disease (IBD) is a chronic, relapsing inflammation disorder of the gastrointestinal tract characterized by disrupted intestinal epithelial barrier function. Despite advances in treatment, including biological agents, achieving sustained remission remains challenging for many patients with IBD. This highlights the urgent need for novel therapeutic strategies.

Role of a Chest X-ray Severity Score in a Multivariable Predictive Model for Mortality in Patients with COVID-19: A Single-Center, Retrospective Study.

Predicting the mortality risk of patients with Coronavirus Disease 2019 (COVID-19) can be valuable in allocating limited medical resources in the setting of outbreaks. This study assessed the role of a chest X-ray (CXR) scoring system in a multivariable model in predicting the mortality of COVID-19 patients by performing a single-center, retrospective, observational study including consecutive patients admitted with a confirmed diagnosis of COVID-19 and an initial CXR. The CXR severity score was calculated by three radiologists with 12 to 15 years of experience in thoracic imaging, based on the extent of lung involvement and density of lung opacities.

Penile ossification of the entire penile shaft found incidentally on pelvic x-ray.

Penile ossification, a rare condition, has been linked traditionally to Peyronie's disease (PD) despite the presence of other less common etiologies. The ossification takes place usually in the mid-shaft of the penis with few cases reporting involvement of the entire shaft. Ultrasound has been the method of choice to demonstrate plaque calcifications.

Decay of the Stress-Induced Ligand MICA Is Controlled by the Expression of an Alternative 3' Untranslated Region.

Recognition of the human stress-induced ligand MHC class I polypeptide-related sequence A (MICA) by the receptor NKG2D expressed on NK cells leads to NK cell-mediated killing of the target cells. Hence, the expression of MICA must be tightly regulated, and its cell surface expression needs to be quickly downregulated to avoid inappropriate activation of immune cells. In this article, we describe a transcript variant of human MICA that has not yet been studied, which contains a 3' untranslated region of 119 nt instead of 174.
