Clinical and Radiological Factors Associated with Nonoperative Management Failure for Small Bowel Obstruction: A Retrospective Study from a Resource-Limited Setting.

Background: Recognizing factors that predict non-operative management (NOM) failure for patients with small bowel obstruction (SBO) aids in limiting surgical intervention when needed. This study investigated the predictive factors for NOM failure in SBO patients in a resource-limited setting.

Material And Method: A retrospective study included 165 patients who were diagnosed with SBO and were admitted and managed at Althora General Hospital, IBB, Yemen, from April 2022 to March 2024.

Allosteric activation of VCP, an AAA unfoldase, by small molecule mimicry.

The loss of function of AAA (ATPases associated with diverse cellular activities) mechanoenzymes has been linked to diseases, and small molecules that activate these proteins can be powerful tools to probe mechanisms and test therapeutic hypotheses. Unlike chemical inhibitors that can bind a single conformational state to block enzyme function, activator binding must be permissive to different conformational states needed for mechanochemistry. However, we do not know how AAA proteins can be activated by small molecules.

The Great Mimicker: Secondary Syphilis-Associated Nephrotic Syndrome in an Adolescent Patient.

Background: Syphilis is long regarded as the "great mimicker" for its variety of symptoms and clinical manifestations. Rarely, it can present with renal involvement, particularly nephrotic syndrome. This is an uncommon initial presentation, particularly in pediatrics.

PEDF-derived peptide protects against Amyloid-β toxicity in vitro and prevents retinal dysfunction in rats.

Amyloid-beta (Aβ), a family of aggregation-prone and neurotoxic peptides, has been implicated in the pathophysiology of age-related macular degeneration (AMD). We have previously shown that oligomeric and fibrillar species of Aβ42 exerted retinal toxicity in rats, but while the consequences of exposure to amyloid were related to intracellular effects, the mechanism of Aβ42 internalization in the retina is not well characterized. In the brain, the 67 kDa laminin receptor (67LR) participates in Aβ-related neuronal cell death.
