Intron removal during pre-mRNA splicing is of extraordinary complexity and its disruption causes a vast number of genetic diseases in humans. While key steps of the canonical spliceosome cycle have been revealed by combined structure-function analyses, structural information on an aberrant spliceosome committed to premature disassembly is not available. Here, we report two cryo-electron microscopy structures of post-B spliceosome intermediates from Schizosaccharomyces pombe primed for disassembly.

However, the impact of trauma-induced hypocalcemia on the haemorrhage remains unclear. It is intuitive to consider perturbations of ionised calcium early during trauma resuscitation in acutely injured patients given its pathophysiological significance for an improved outcome.

Methods: This long-term prospective study enrolled patients with histologically confirmed head and neck carcinoma, all receiving VMAT treatment. Audiological assessments were done using various tests at baseline, two weeks, treatment completion, six months, and 12 months.
Background And Objectives: This study aimed to evaluate whether preoperative oral prednisolone improves the intraoperative parameters and postoperative outcomes over a 3-month period in patients of sinonasal polyposis who undergo functional endoscopic sinus surgery.
Methods: In a triple-blind, randomized controlled study, 43 patients diagnosed with sinonasal polyposis in the Department of ENT, AIIMS, Jodhpur, were enrolled. After obtaining institutional ethics clearance and registering the clinical trial, randomization was conducted to assign participants into experimental and control groups.
Background: Legumes are widely considered one of the most beneficial food groups to consume. They are high in fibre and plant-based protein as well as naturally low in sodium, saturated fats, and sugars. However, legumes do not feature prominently in the modern diet, and previous evidence syntheses show inconsistent results on cardiometabolic risk profile when increasing legume intakes.
