Objectives: Athletes commonly wear fitted silicone ankle sleeves (SAS) and lace-up ankle braces (LAB). There is limited data about their effect on neuromuscular control or athletic performance. Our goal is to evaluate their efficacy in a young, active population during athletic tasks using motion analysis. Methods: Ten subjects (5 males, 5 females) without prior musculoskeletal injury were recruited. They were asked to perform the Drop Vertical Jump test (DVJ), 45 degree bound, and cutting maneuvers under three conditions: No brace, SAS, LAB. DVJ was used as a surrogate for neuromuscular contr

Bumble bees are important pollinators of crops and other plants. However, many aspects of their basic biology remain relatively unexplored. For example, one important and unusual natural history feature in bumble bees is the massive size variation seen between workers of the same nest. This size polymorphism may be an adaptation for division of labor, colony economics, or be nonadaptive. It was also suggested that perhaps this variation allows for niche specialization in workers foraging at different temperatures: larger bees might be better suited to forage at cooler temperatures and smaller

Abstract Background Mechanical ventilation with high tidal volumes may cause ventilator-induced lung injury (VILI) and enhanced generation of nitric oxide (NO). We demonstrated in sheep that pneumonectomy followed by injurious ventilation promotes pulmonary edema. We wished both to test the hypothesis that neuronal NOS (nNOS), which is distributed in airway epithelial and neuronal tissues, could be involved in the pathogenesis of VILI and we also aimed at investigating the influence of an inhibitor of nNOS on the course of VILI after pneumonectomy. Methods Anesthetized sheep underwent right pn

As a developing country, Indonesia shows a quite interesting phenomenon, which is the high rate of debt of many companies in Indonesia. This fact shows that the policy of leverage plays an important role for the viability of the company. The main purpose of this research was to test empirically factors influencing leverage, for there are still inconsistencies in research results from the prior studies. Based on the data of the mining companies listed on BEI for period 2009-2011, in addition of using tax factors that consisted of Corporate tax rate and Non-debt tax shield, influencing the lever

BACKGROUND: Current treatments for idiopathic inflammatory myopathies (collectively called myositis) focus on the suppression of an autoimmune inflammatory response within the skeletal muscle. However, it has been observed that there is a poor correlation between the successful suppression of muscle inflammation and an improvement in muscle function. Some evidence in the literature suggests that metabolic abnormalities in the skeletal muscle underlie the weakness that continues despite successful immunosuppression. We have previously shown that decreased expression of a purine nucleotide cycle

The frequency of heat shocks during grain filling of wheat crops across the Australian wheatbelt has significantly increased over the last 30 years. These post-flowering heat events significantly reduce wheat yields with a relatively greater impact on grain size than grain number. A controlled environment study was conducted to assess the impact of post-flowering heat shocks on wheat recombinant inbred lines SB062 and SB003. Plants were submitted to 7-day heat shocks (33/21 °C day/night temperature) at different periods during grain filling. Heat shocks significantly accelerated leaf senescenc

BACKGROUND: Acute traumatic coagulopathy (ATC) has been linked to an increase in activated protein C (aPC) from 40 pM in healthy individuals to 175 pM. aPC exerts its activity primarily through cleavage of active coagulation factor Va (fVa). Platelets reportedly possess fVa which is more resistant to aPC cleavage than plasma fVa; this work examines the hypothesis that normal platelets are sufficient to maintain coagulation in the presence of elevated aPC. METHODS: Coagulation responses of normal plasma, fV deficient plasma (fVdp), and isolated normal platelets in fVdp were conducted: prothromb
