Influence of cold ischemia time on complement activation, neopterin, and cytokine release in liver transplantation.

2004

The aim of this study was to determine whether a cold ischemia time (CIT) of12 hours influences the activation of complement as well as the plasma concentrations of neopterin, interleukin (IL)-6, or IL-8 in orthotopic liver transplantation (OLT).Eighteen consecutive patients undergoing OLT using a veno-venous bypass technique were divided into 2 groups: duration of CIT12 hours (group 1; n = 11), and CIT12 hours (group 2; n = 7). Blood samples were drawn preoperatively, 1 minute before, and 120 minutes after reperfusion.Preoperatively, complement split products, neopterin, IL-6, and IL-8 levels did not differ between the groups. At 120 minutes after reperfusion, the concentrations of C3a, SC…

Multi Regression Analysis of Skin Temperature Variation During Cycling Exercise

2017

In the last years, infrared thermography (IRT) has become a popular technique to determine human skin temperature during exercise [1–3]. IRT presents several applications in sport science such as the detection of injury, the thermophysiology assessment, the sport clothing assessment/design, or its application in equestrian sport, among others [3]. However, IRT in sports is still a recent topic and there are many fundamental discussions concerning different methodological aspects, being one of them the analysis of the thermal data [4].

Cardiac arrest in older adult patients

2021

Purpose of review To describe the epidemiology, prognostication, and treatment of out- and in-hospital cardiac arrest (OHCA and IHCA) in elderly patients. Recent findings Elderly patients undergoing cardiac arrest (CA) challenge the appropriateness of attempting cardiopulmonary resuscitation (CPR). Current literature suggests that factors traditionally associated with survival to hospital discharge and neurologically intact survival after CA cardiac arrest in general (e.g. presenting ryhthm, bystander CPR, targeted temperature management) may not be similarly favorable in elderly patients. Alternative factors meaningful for outcome in this special population include prearrest functional sta…

The Use of infrared thermography in the study of sport and exercise physiology

2016

Infrared thermography (IRT) is considered an upcoming, promising methodology in the field of exercise physiology. Skin temperature distribution derives from muscular activity, skin blood flow as well as perspiration patterns in specific body parts. This chapter aims to provide a general overview on the literature about the study of the skin temperature response to exercise assessed by means of IRT and its relationship with other thermoregulatory variables, exercise characteristics and performance factors.

Neuropeptides, neurogenic inflammation and complex regional pain syndrome (CRPS)

2008

This review explains symptoms and nature of neuropeptide signaling and its importance for clinical symptoms of CRPS. Neurogenic inflammation regularly accompanies excitation of primary afferent nociceptors. It has two major components-plasma extravasation and vasodilatation. The most important mediators are the calcitonin gene-related peptide (CGRP) and substance P (SP). After peripheral trauma immune reaction (e.g. cytokines) and the attempts of the tissue to regenerate (e.g. growth factors) sensitize nociceptors and amplify neurogenic inflammation. This cascade of events has been demonstrated in rat models of CRPS. Clinical findings in these animals strongly resemble clinical findings in …

Individualized analysis of skin thermosensory thresholds and sensitivity in heat-sensitive people with multiple sclerosis

2020

We investigated whether and how multiple sclerosis (MS) alters thresholds for perceiving increases and decreases in local skin temperature, as well as the sensitivity to progressively greater temperature stimuli, amongst heat-sensitive people with MS. Eleven MS patients (5 M/6 F; 51.1 ± 8.6 y, EDSS 5.7 ± 1.9) and 11 healthy controls (CTR; 7 M/4 F; 50.3 ± 9.0 y) performed warm and cold threshold tests on a hairy skin site, on both sides of the body. They also underwent a thermosensitivity test where they rated (visual analogue scale) perceived magnitude of 4 local skin stimuli (i.e. 22, 26, 34, 38°C). Individual thresholds and slopes of linear regression for thermosensitivity were z-transfor…

Effects of 24 h Compression Interventions with Different Garments on Recovery Markers during Running

2021

Compression and temperature manipulation are discussed as strategies to improve performance markers and recovery in sports. Here, we investigate the effects of compression stockings made with fabric, either combined or not with heating and cooling substances, on variables related to running performance and recovery. Ten trained runners (mean ± standard deviation age 45 ± 9 years old, body mass 69 ± 7 kg, height 166 ± 4 cm) with no experience of using compression garments performed an intense running session of 10 km, then wore a stocking for 24 h (randomized

Biotic oxidation of methane in landfills in boreal climatic conditions

2010

 This study focused on the biotic oxidation of methane in landfill covers as a technology for reducing greenhouse gas emissions from landfills, particularly those located in the boreal climatic zone. First, methane oxidation was studied in laboratory batch assays in a landfill cover soil consisting of a composted mixture of sewage sludge and chemical sludge which had been installed on the landfill surface 4-5 years earlier. Second, methane oxidation was studied using mechanically-biologically treated municipal solid waste (MBT residual) as a material for methane-oxidizing landfill covers both in continuously methane-sparged laboratory columns and in an outdoor pilot lysimeter. Finally, meth…
