Physical limits to biochemical signaling.
Many crucial biological processes operate with surprisingly small numbers of molecules, and there is renewed interest in analyzing the impact of noise associated with these small numbers. Twenty-five years ago, Berg and Purcell showed that bacterial chemotaxis, where a single-celled organism must respond to small changes in concentration of chemicals outside the cell, is limited directly by mol...
متن کاملThe Biochemical Response to Trauma
The changes that occur in the concentration of chemical constituents of plasma and damaged tissue following trauma have been investigated for many years. The biochemical changes following burns (1) and hemorrhage (2), the protein changes under similar types of injury (3), and those in the nitrogenous compounds (4) have been studied in some detail, and Engel (5) has recently reviewed several asp...
متن کاملThe biochemical response to biomechanical tissue loading on the low back during physical work exposure.
BACKGROUND Our understanding of low back disorder causality is limited in that how biomechanical loading acting on various spinal tissues initiates the pain pathway is not clear. Previous studies suggest that cytokines may be important in mediating the inflammatory responses in patients with back pain. This study quantified the acute biochemical responses to physical work stressing the low back...
متن کاملNox response to injury.
Szöcs and colleagues, 1 in this issue of Arteriosclerosis, Thrombosis and Vascular Biology, have added to our understanding of the role of NAD(P)H oxidase and reactive oxygen species in vascular injury. The study was undertaken by using the rat carotid artery balloon injury model, a well-characterized model of neointimal formation. In this model, vascular balloon injury leads to medial smooth m...
متن کاملBiochemical Response to Hyperbaric Oxygen Treatment of a Transhemispheric Penetrating Cerebral Gunshot Injury
Hyperbaric oxygen (HBO) therapy has been suggested a treatment option in order to reduce the development of secondary insults succeeding traumatic brain injury. This case report studied the course of a 23-year-old gentleman with a close range transhemispheric gunshot wound. The biochemical parameters, using a multi-modal monitoring in the neuro-intensive care unit, improved following HBO treatm...
