Background: Xylogenesis is synchronous among trees in regions with a distinct growing season, leading to a forest-wide time lag between growth and carbon uptake. In contrast, little is known about interspecific or even intraspecific variability of xylogenesis in tropical forests. Yet an understanding of xylogenesis patterns is key to successfully combine bottom-up (e.

The delivery of intracellular cargoes by kinesins is modulated at scales ranging from the geometry of the microtubule networks down to interactions with individual tubulins and their code. The complexity of the tubulin code and the difficulty in directly observing motor-tubulin interactions have hindered progress in pinpointing the precise mechanisms by which kinesin's function is modulated. As one such example, past experiments show that cleaving tubulin C-terminal tails (CTTs) lowers kinesin-1's processivity and velocity on microtubules, but how these CTTs intertwine with kinesin's processive cycle remains unclear.

Background: Shunt nephritis, although rare, should be high in the differential diagnoses for patients with gross or microscopic hematuria and a history of a ventriculoatrial/cystoatrial shunt.
Observations: The authors present the case of a 31-year-old female with a history of a resected posterior fossa hemangioblastoma and hydrocephalus, who presented to the nephrology clinic with night sweats and tea-colored urine for 3 months after being hospitalized for a saddle pulmonary embolism; kidney biopsy was contraindicated. The patient had hypocomplementemia, nephrotic-range proteinuria, positive proteinase 3-specific antineutrophil cytoplasmic antibody, and dysmorphic red blood cells in the urine sediment.
The Impact of Histopathology on Medical Board Autopsies.
Cureus
February 2025
Department of Forensic Medicine and Toxicology, Rajendra Institute of Medical Sciences, Ranchi, IND.
Background: Histopathological examination, although mostly limited to scenarios where the cause of death is not readily apparent during the autopsy, possesses substantial significance in medico-legal autopsies conducted by medical boards, as it provides essential insights into both the causation and circumstances contributing to death. Diverse viewpoints persist about how histopathology is utilized in the context of medico-legal autopsies. This study examines the significance of histopathology in elucidating particular causes of death in medico-legal autopsies conducted by a medical board of doctors, with a predominant proportion of cases of custodial deaths.

Purpose: This case report is to present the anatomical variation of ectopic pancreas and discuss about its clinical significance.
Methods: While dissecting an adult cadaver specimen, an ectopic pancreas specimen was found.
Results: The ectopic pancreatic tissue was located in the left lobe of the liver and the mesentery.
