ConclusionsThe presence of abnormal18F-FDG uptake adjacent to the ischial tuberosities together with findings at the peri-articular shoulder or interspinous bursa on whole-body PET/CT is highly sensitive and specific for a diagnosis of PMR.Trial registrationClinical Trial Registration: Australian New Zealand Clinical Trials Registry,http://www.anzctr.org.au, ACTRN1261400696695

ConclusionIn order to overcome those key challenges arising from CT datasets and solve some of the main problems existing in the current deep learning-based methods, we propose a novel unified CTumorGAN framework, which can be effectively generalized to address any kinds of tumor datasets with superior performance.

Abstract The Na+/Ca2+ exchanger type-1 (NCX1) is a bidirectional transporter that is controlled by membrane potential and transmembrane gradients of Na+ and Ca2+. Vascular smooth muscle NCX1 plays an important role in intracellular Ca2+ homeostasis and Ca2+ signaling. We found that NCX1 was upregulated in the pulmonary arteries of mice exposed to chronic hypoxia (10% O2 for 4 weeks). Hence, we investigated the pathophysiological role of NCX1 in hypoxia-induced pulmonary arterial hypertension (PAH), using NCX1-heterozygous (NCX1+/-) mice, in which NCX1 expression is reduced by half, and SEA0400, a specific NCX1 inh...

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

In this study, we examined the benefits of early-onset, lifelong AET on predictors of health, inflammation, and cancer incidence in a naturally aging mouse model. Lifelong, voluntary wheel-running (O-AET; 26-month-old) prevented age-related declines in aerobic fitness and motor coordination vs. age-matched, sedentary controls (O-SED). AET also provided partial protection against sarcopenia, dynapenia, testicular atrophy, and overall organ pathology, hence augmenting the 'physiologic reserve' of lifelong runners. Systemic inflammation, as evidenced by a chronic elevation in 17 of 18 pro- and anti-inflammatory cytokin...

SPECIAL FROM “As many as five million Americans age 65 and older may have Alzheimer’s Disease, and that number is expected to double for every five-year interval beyond age 65.” — the National Institute of Neurologic Disorders and Stroke. While Alzheimer’s is the most common form of dementia, it is not the only form. Risk factors for all kinds of dementia include, age, alcohol use, smoking, atherosclerosis, diabetes, hypertension, and genetics. However, researchers have found some startling connections that show other surprising factors that can heighten your risk: Risk Factor #1: Anticho...
