S100α and S100β proteins in human cutaneous sensory corpuscles: Effects of nerve and spinal cord injury
S100 protein in the vertebrate peripheral nervous system consists of homo- or heterodimers of S100α and S100β proteins, the first predominating in neurons and the second in glial cells. Recently, however, occurrence of S100β protein in neurons has been reported. The expression of S100 protein by Schwann cells, as well as their derivatives in sensory corpuscles, depends on the sensory axon (i.e., the Schwann cell–axon contact). The present study analyzed the distribution of S100α and S100β proteins in human cutaneous sensory corpuscles and the effects of peripheral or central sensory axon severance in the expression of these proteins. Simple or double immunohistochemistry was carried out usi…
Left Renal Vein Anatomical Anomalies: Radiological and Surgical Implications
Objective: To emphasize the incidence and clinical, diagnostic and surgical implications of left renal vein developmental anomalies. Design: Retrospective analysis of case notes. Setting: Clinical Anatomy Department and Surgery Department, Faculty of Medicine, University of Valencia, Spain. Patients, participants: Standard radiological examinations (CT scan) performed on 745 patients; surgical findings at operation in 128 patients with aorto-iliac atherosclerotic disease, and 72 donor cadavers for transplantation. Main outcome measures: Incidence of left renal vein anomalies (retro-aortic left renal vein and peri-aortic renal venous collar), based on radiological (CT scan) and surgical obse…
