Priming with a Combination of Proangiogenic Growth Factors Enhances Wound Healing in Streptozotocin-Induced Diabetes in Mice
2010
<i>Background:</i> Numerous proangiogenic growth factors have been shown to improve impaired wound healing. This study evaluated the effects of subcutaneous pretreatment with a combination of proangiogenic growth factors on wound closure, mechanical properties, vessel density, and morphology. <i>Methods:</i> Thirty-six Balb/c mice with streptozotocin-induced diabetes were divided into 3 groups. A mixture of VEGF (35.0 µg), bFGF (2.5 µg), and PDGF (3.5 µg) was administered subcutaneously 3, 5, and 7 days prior to wounding in the first group, whereas the second group received three doses of 3.5 µg PDGF. Wound sizes were assessed daily and the repaired tissues were harv…
Thermographic quantitative variables for diabetic foot assessment: preliminary results
2018
The aim of this study was to define aspects of a protocol for a diabetic population by obtaining and evaluating thermographic images following thermal stress (cooling of the sole of the foot with c...
Muscular Strength Imbalances Are not Associated with Skin Temperature Asymmetries in Soccer Players
2020
Although strength imbalances using isokinetic dynamometer have been examined for injury risk screening in soccer players, it is very expensive and time-consuming, making the evaluation of new methods appealing. The aim of the study was to analyze the agreement between muscular strength imbalances and skin temperature bilateral asymmetries as well as skin temperature differences in the hamstrings and quadriceps. The skin temperature of the anterior and posterior thigh of 59 healthy male soccer athletes was assessed at baseline using infrared thermography for the identification of hamstrings-quadriceps skin temperature differences and thermal asymmetries (>
Reproducibility of Skin Temperature Response after Cold Stress Test Using the Game Ready System: Preliminary Study
2021
The objective of this preliminary study was to determine the reproducibility of lower limbs skin temperature after cold stress test using the Game Ready system. Skin temperature of fourteen participants was measured before and after cold stress test using the Game Ready system and it was repeated the protocol in four times: at 9:00, at 11:00, at 19:00, and at 9:00 h of the posterior day. To assess skin temperature recovery after cold stress test, a logarithmic equation for each region was calculated, and constant (β0) and slope (β1) coefficients were obtained. Intraclass correlation coefficient (ICC), standard error (SE), and within-subject coefficient of variation (CV) were determined. No …
Measurement of energy expenditure by activity monitors: is it feasible to measure energy expenditure using tiny portable monitors?
2013
Physical inactivity has a major health effect worldwide. It is stated in the currently published physical activity recommendations for adults to promote and maintain health, that all healthy adults need moderate intensity physical activity for a minimum of 30 minutes, 5 days per week or vigorous intensity aerobic physical activity for a minimum of 20 minutes, 3 days per week. Physical activity can be defined as any bodily movement produced by the contraction of skeletal muscles that substantially increases energy expenditure and is characterised by its intensity, duration, frequency and mode of activity. Ideally, all these aspects should be recorded during physical activity measurements. Ho…
Thermographic imaging in sports and exercise medicine:a Delphi study and consensus statement on the measurement of human skin temperature
2017
© 2017 Elsevier Ltd The importance of using infrared thermography (IRT) to assess skin temperature (t sk ) is increasing in clinical settings. Recently, its use has been increasing in sports and exercise medicine; however, no consensus guideline exists to address the methods for collecting data in such situations. The aim of this study was to develop a checklist for the collection of t sk using IRT in sports and exercise medicine. We carried out a Delphi study to set a checklist based on consensus agreement from leading experts in the field. Panelists (n = 24) representing the areas of sport science (n = 8; 33%), physiology (n = 7; 29%), physiotherapy (n = 3; 13%) and medicine (n = 6; 25%…
Increased pain and neurogenic inflammation in mice deficient of neutral endopeptidase
2009
The complex regional pain syndrome (CRPS) is characterized by enhanced neurogenic inflammation, mediated by neuropeptides. Neutral endopeptidase (NEP) is a key enzyme in neuropeptide catabolism. We used NEP knock out (ko) mice to investigate whether NEP deficiency leads to increased pain behavior and signs of neurogenic inflammation after soft tissue trauma with and without nerve injury. After chronic constriction injury (CCI) of the right sciatic nerve, NEP ko mice were more sensitive to heat, to mechanical stimuli, and to cold than wild type mice. Tissue injury without nerve injury produced no differences between genotypes. After CCI, NEP ko mice showed increased hind paw edema but lower …
Peripheral Changes in Blood Circulation during Autogenic Training and Hypnosis (Results of Experimental Research)
1969
In addition to the immobilization of the limbs and the associated sensation of heaviness, most patients in a hypnotic trance also experience a sensation of warmth. This subjective feeling is probably accompanied by increased skin temperature. Attempts have been made in the past to record skin temperature objectively. Most methods of measurement, however, are so defective that they have only rarely proved at all reliable. Hensel (1955, 1964) and his colleagues have described seven variables whose range is so great that the statistical evaluation of such measurements becomes impossible, even though the data may be valid in individual cases. Furthermore, graphic recording is also impracticable…
Relationship between Skin Temperature Variation and Muscle Damage Markers after a Marathon Performed in a Hot Environmental Condition
2021
This study aimed to assess the effect of a marathon running at a hot environmental temperature on the baseline skin temperature (Tsk) of the posterior day and to analyze the relationship between Tsk response and muscle damage markers variation. The Tsk, creatine kinase, and lactate dehydrogenase of 16 marathon runners were assessed four times before (15 days and 45 min) and after (24 h and 6 days) a marathon in a hot environment (thermal stress index = 28.3 ± 3.3 °C and humidity ~81%). The Tsk of thirteen different body regions of both right and left lower limbs were analyzed. Higher values after the marathon were observed than 45 min before in creatine kinase (174.3 ± 136.4 UI/L <
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].
