The first case of cutaneous clear cell perivascular epithelioid cell tumor (PEComa) with negative HMB-45 marker is presented. The tumor was a nodule 3x2 cm in size, located on the right foot in a 60-year-old man. The lesion consisted of large irregularly shaped cells with clear cytoplasm, negative for S-100 protein, HMB-45, Melan-A, pancytokeratin, epithelial membrane antigen and CAM5.2. Multif...

The purpose of this study was to examine the effect of β-hydroxy-β-methylbutyrate-free acid (HMB-FA) and cold-water immersion (CWI) on circulating concentrations of TNF-α and monocyte TNF-α receptor 1 (TNFR1) expression. Forty resistance-trained men (22.3 ± 2.4 yr) were randomized into four groups [placebo (PL), HMB-FA, CWI, and HMB-FA-CWI] and performed an acute, intense exercise protocol (fou...

In ovo feeding, injecting nutrients into the amnion of the avian embryo, may enhance jejunal nutrient uptake, activity of the intestinal enzymes, and posthatch growth. This hypothesis was tested in the following in ovo feeding (IOF) experiments. In experiment 1, 400 eggs were evenly distributed among 4 nutritional treatments at 23 d of embryonic development (23E) and administered 1 of 4 treatme...

To identify the prevalence and impact of heavy menstrual bleeding (HMB) in exercising females where anemia may have a significant effect on training and performance a 'Female Health Questionnaire' was designed incorporating a validated diagnostic HMB series, demographics, exercise ability data, training status, anemia, iron supplementation and whether the menstrual cycle had affected training a...

Background Beta-hydoxy-beta-methyl butyrate (HMB) when given over a two-week period of time (loading phase) has been demonstrated to decrease skeletal muscle damage, and improve recovery. However, few studies have investigated its acute effects on muscle damage and recovery. Therefore the purpose of this investigation was to determine the effects of short term free acid HMB (HMB-FA) supplementa...

Background: Heavy menstrual bleeding (HMB) is defined as excessive blood loss which interferes with a woman's physical, social, emotional and/or material quality of life. It can occur alone or in combination other symptoms. Thyroid hormone affects pattern. The objective this study was to evaluate thyroid function women menorrhagia (HMB).Methods: type journal article. Study design- retrospective...

BACKGROUND Platelet function disorders (PFDs) have emerged as an important etiology of heavy menstrual bleeding (HMB) in adolescents. However, neither clinical nor laboratory data have been methodically analyzed in this population subset. The objective of this study was to evaluate these parameters in order to distinguish characteristics of the disorder that in turn will lead to earlier diagnos...

In order to improve the performance of a magnetically levitated (maglev) axial flow blood pump, three-dimensional (3-D) finite element analysis (FEA) was used to optimize the design of a hybrid magnetic bearing (HMB). Radial, axial, and current stiffness of multiple design variations of the HMB were calculated using a 3-D FEA package and verified by experimental results. As compared with the or...

OBJECTIVES Total knee arthroplasty (TKA) performed in knee osteoarthritis patients is reported to be immediately followed by a decrease in quadriceps muscle strength. We investigated the effects of supplementation with a combination β-hydroxy-β-methyl butyrate, L-arginine, and L-glutamine (HMB/Arg/Gln) on the postoperative recovery of quadriceps muscle strength in patients after TKA. METHODS ...

BACKGROUND Formation of compact and poorly lysable clots has been reported in thromboembolic disorders. Little is known about clot properties in bleeding disorders. OBJECTIVES We hypothesized that more permeable and lysis-sensitive fibrin clots can be detected in women with heavy menstrual bleeding (HMB). METHODS We studied 52 women with HMB of unknown cause and 52 age-matched control women...
