A union of two rare pathologies: small bowel diverticula perforation secondary to impacted gallstone ileus.

An 84-year-old lady presented with 1 day history of sudden onset generalized abdominal pain, fevers, and peritonism. Computed tomography was suggestive of a mid-small bowel perforation associated with a distal ovoid soft tissue density structure without pneumobilia. An urgent laparotomy demonstrated two areas of jejunal diverticula necrosis and perforation associated with a 3 cm luminal mass in the proximal ileum, and proximal small bowel dilatation.

Engineered receptors for soluble cellular communication and disease sensing.

Despite recent advances in mammalian synthetic biology, there remains a lack of modular synthetic receptors that can robustly respond to soluble ligands and, in turn, activate bespoke cellular functions. Such receptors would have extensive clinical potential to regulate the activity of engineered therapeutic cells, but so far only receptors against cell-surface targets have approached clinical translation. To address this gap, here we adapt a receptor architecture called the synthetic intramembrane proteolysis receptor (SNIPR) for activation by soluble ligands.

Untreated Vestibular Schwannoma: Analysis of the Determinants of Growth.

The growth rate of sporadic VS varies considerably, posing challenges for consistent clinical management. This systematic review examines data on factors associated with VS growth, following a protocol registered in the PROSPERO database. The analysis reveals that key predictors of tumor growth include tumor location, initial size, and specific clinical symptoms such as hearing loss and imbalance.

Characterization and quantification of peptaibol produced by novel Trichoderma spp: Harnessing their potential to mitigate moisture stress through enhanced biochemical and physiological responses in black pepper (Piper nigrum L.).

Trichoderma spp. is primarily applied to manage biotic stresses in plants. Still, they also can mitigate abiotic stresses by the stimulation of antioxidative protective mechanisms and enhanced synthesis of secondary metabolites.

AP-1 Mediates Cellular Adaptation and Memory Formation During Therapy Resistance.

Cellular responses to environmental stimuli are typically thought to be governed by genetically encoded programs. We demonstrate that melanoma cells can form and maintain cellular memories during the acquisition of therapy resistance that exhibit characteristics of cellular learning and are dependent on the transcription factor AP-1. We show that cells exposed to a low dose of therapy adapt to become resistant to a high dose, demonstrating that resistance was not purely selective.
