of the contracting force of hip extension. In consideration of the fiber arrangement of the GM, it was necessary to create a RUSI protocol that used measurements of the upper fibers. In addition, the difference in muscle thickness due to different angles of abduction affected the sample size and significance of results. This study had several limitations. First, all participants were young... Objective: The aim of this study was to investigate the inter-rater and intra-rater reliability of rehabilitative ultrasound imaging (RUSI) for measurement of muscle thickness with changes in angles of the gluteus maximus (GM) at rest and during contraction. Design: Cross-sectional study. Methods: Twenty-two healthy men volunteered for this study. GM muscle images were obtained in the resting position and during prone hip extension with knee flexion at hip abduction angles of 0° and 30°,... -

Design: Cross sectional study. Methods: This study consisted of 25 young (age 20 years), 24 elderly (age 65-74 years), and 25 very elderly (age 75-90 years) people with no physical dysfunctions. The cross sectional area (CSAs) of the RF and muscle thickness of the TA and GMM were measured at... -

The ADIM is designed to acti- vate the TrA while minimally contracting the internal obli- que (IO) and external oblique (EO) muscles [19]. Previous studies involving ADIM have been performed with subjects in various positions such as supine, crook lying, sitting, four points kneeling, and wall support standing [20-22]. O’Sullivan [23] recommends weight-bearing positions such as standing as a... Objective: To investigate the appropriate position for abdominal drawing-in maneuver (ADIM) exercise by rehabilitative ultrasound image. Design: Cross-sectional study. Methods: Twenty-eight young adults with no history of low back pain participated in the study. Three positions compared were crook lying position with hip 60o flexion, standing position with the feet hip width apart and knees straight, and saddle standing positionunsupported with the knees 20° flexed. Once in the appropriate... -

Terraciano P, Garcez T, Ayres L, Durli I, Baggio M, Kuhl CP, Laurino C, Passos E,... Mesenchymal stem cells (MSCs) have desirable characteristics for use in therapy in animal models and veterinary medicine, due to their capacity of inducing tissue regeneration and immunomodulation. The objective of this study was to evaluate the differences between canine adipose tissue-derived MSCs (AD-MSCs) extracted from subcutaneous (Sc) and visceral (Vs) sites. Surface antigenic markers, in vitro differentiation, and mineralized matrix quantification of AD-MSCs at different passages (P4,... -

cyclooxygenase dependent contracting factor, being this an important key role in the development of hypertension. On the other hand, quantitative regional differences in the inhibition of the phenylephrine-induced contraction in rat aorta has been described [14]. Indomethacin inhibited this contraction in the abdominal but not thoracic segment, suggesting the participation of prostanoids in... Vascular reactivity can be influenced by the vascular region, animal age, and pathologies present. Prostaglandins (produced by COX-1 and COX-2) play an important role in the contractile response to phenylephrine in the abdominal aorta of young rats. Although these COXs are found in many tissues, their distribution and role in vascular reactivity are not clear. At a vascular level, they take part in the homeostasis functions involved in many physiological and pathologic processes (e.g., arterial... -

blood may contribute to endothelial dysfunction by mediating abnormal endothelial permeability or an imbalance between endothelium-derived relaxing and contracting factors [2-8]. Several previous studies also demonstrated that prolonged exposure to high glucose may affect endothelium-dependent vasodilation by stimulating the production of reactive oxygen species (ROS) [9-12] or voltage-gated... Hyperglycemia is associated with an increased risk of cardiovascular diseases. It has been demonstrated that chronic exposure to high glucose impaired endothelial functions. However, specific effects of short-term exposure to high glucose on vascular reactivity are controversial. Moreover, the combined effects of other metabolic substrates such as free fatty acids (FFA) on vascular reactivity remain poorly understood. Here we investigate the effects of short-term exposure to high glucose with or... -

study showed that, in addition to its effect on vasoconstriction, DEX seemed to have a vasodilatory effect through the activation of endothelial NOS in human pulmonary arteries. The relaxing and contracting effects of DEX oppose each other, resulting in little change in tension in quiescent arteries with endothelium. It is plausible that DEX may induce greater pulmonary artery resistance in... Despite the complex vascular effects of dexmedetomidine (DEX), its actions on human pulmonary resistance arteries remain unknown. The present study tested the hypothesis that DEX inhibits vascular tension in human pulmonary arteries through the endothelial nitric oxide synthase (eNOS) mediated production of nitric oxide (NO). Pulmonary artery segments were obtained from 62 patients who underwent lung resection. The direct effects of DEX on human pulmonary artery tension and changes in vascular... -

in contracting rat skeletal muscle: adaptation to exercise training. Am J Physiol. 1987;253:C316-322. 5. Takada S, Kinugawa S, Matsushima S, Takemoto D, Furihata T, Mizushima W, Fukushima A, Yokota T, Ono Y, Shibata H, Okita K, Tsutsui H. Sesamin prevents decline in exercise capacity and impairment of skeletal muscle mitochondrial function in mice with high-fat diet-induced diabetes. Exp... Involuntary physical activity induced by the avoidance of electrical shock leads to improved endurance exercise capacity in animals. However, it remains unknown whether voluntary stand-up physical activity (SPA) without forced simulating factors improves endurance exercise capacity in animals. We examined the eff ects of SPA on body weight, cardiac function, and endurance exercise capacity for 12 weeks. Twelve male Sprague-Dawley rats (aged 8 weeks, n=6 per group) were randomly assigned to a... -

els, increased AChE activity and oxidative stress. Endothelin (ET) being the most potent endothelium-deri- ved contracting factor has been demonstrated to exist in three isoforms i.e. ET-1, ET-2 and ET-3. Out of the three isoforms, ET-1 is most widely studied and considered to be an important mediator of different physiological and patho- physiological functions [46]. The biological effects of... The present study was designed to investigate the efficacy of selective ETA receptor antagonist, ambrisentan on hyperhomocysteinemia-induced experimental vascular dementia. L-methionine was administered for 8 weeks to induce hyperhomocysteinemia and associated vascular dementia in male rats. Ambrisentan was administered to L-methionine-treated effect rats for 4 weeks (starting from 5th to 8th week of L-methionine treatment). On 52nd day onward, the animals were exposed to the Morris water maze... -

Many participants reported that they were afraid of CO- VID-19 (76.9%) and that they were at risk of contracting the virus (75.9%). The most common sources of information related to COVID-19 were broadcasting (43.2%), but it was similar to social network service (SNS, 42.2%). Regarding the question... Purpose: This cross-sectional study aimed to identify factors affecting coronavirus disease 2019 (COVID-19) vaccination intention. Methods: For an anonymous online survey, recruitment notices were posted on an anonymous community by each university, and an online survey was conducted through online form from June to July 2021. COVID-19 knowledge and health-protective behavior were measured using a questionnaire based on previous literature and reflecting the Korea Centers for Disease Control and...
