BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is still largely underdiagnosed in the general population. Although transthoracic echocardiogram (TTE) is recommended to screen for CTEPH, it may not detect patients with chronic thromboembolic disease (CTED) and mild or exercise-induced pulmonary hypertension (PH) who could also benefit from pulmonary endarterectomy (PEA). METHODS: All patients referred to our CTEPH program with persistent mismatched perfusion defects on ventilation-perfusion (VQ) scan between January 2005 and June 2015 were divided into three groups according to TTE and right heart catheterization (RHC) as follows: (1) typical CTEPH group (PH on RHC and TTE), (2) TTE-negative (neg) CTEPH group (PH on RHC, but not TTE), or (3) CTED group (no PH on RHC and TTE)...

The hemodynamic effects of ventilation can be grouped into three concepts: 1) spontaneous ventilation is exercise; 2) changes in lung volume alter autonomic tone, pulmonary vascular resistance, and can compress the heart in the cardiac fossa; 3) spontaneous inspiratory efforts decrease intrathoracic pressure (ITP) increasing venous return and impeding left ventricular (LV) ejection; whereas positive pressure ventilation decreases venous return and unloads LV ejection. Spontaneous inspiratory efforts may induce acute LV failure and cardiogenic pulmonary edema...

Negative effort dependence (NED), decreased airflow despite increased driving pressure, has been proposed as a specific obstructive sleep apnea (OSA) phenotypic characteristic. We examined conditions under which NED occurs in a collapsible tube, chamber enclosed, pharyngeal airway bench model, focusing on relationships with surrounding pressure levels and longitudinal strain. Using a vacuum source, graded airflows (V ̇, 0-5 L/s) were generated through a thin walled latex tube enclosed within a rigid, cylindrical chamber, sealed with initial chamber pressures (Pci) of 0-5 cmH2O (separate runs), or open to atmosphere...

The microgravity ocular syndrome (MOS) results in significant structural and functional ophthalmic changes during 6-month spaceflight missions consistent with an increase in cerebrospinal fluid (CSF) pressure compared to the preflight upright position. A ground-based study was performed to assess two of the major hypothesized contributors to MOS, headward fluid shifting and increased ambient CO2, on intracranial and periorbital CSF. In addition, lower body negative pressure (LBNP) was assessed as a countermeasure to headward fluid shifting...

BACKGROUND: Intermittent artificial gravity (AG) training over days and weeks has been shown to improve the human orthostatic tolerance limit (OTL) and improve cardiovascular regulation in response to orthostatic stress. Effects of a single AG exposure are currently unknown. METHODS: We tested cardiovascular responses to orthostatic stress in 16 hypovolemic subjects (9 men and 7 women), once following a single, short (∼90 min) bout of AG and once following a similar period of head-down bed rest (HDBR)...

Diabetes is a serious disease with severe side effects and comorbidities. Diabetic foot with its chronic non-healing ulcers, or diabetic food ulcers (DFU) as they are commonly called, can be devastating, even leading to amputation. Many therapies exist to assist and improve wound healing. One exciting discovery is the use of negative pressure wound therapy (NPWT) as an adjunct to standard treatment. Few studies have substantively explored the molecular mechanisms of NPWT and why we see improved wound healing, a concept that demands more research...

BACKGROUND: Bone-exposed wounds with intact or defected periosteum are difficult to heal. To provide relevant experimental evidence for guidance of clinical therapy, we established a rabbit model to compare the efficacies of negative pressure wound therapy (NPWT) and conventional guaze dressing therapy on the healing of cranial bone-exposed wounds. METHODS: Full-thickness excisional circular wounds of 2.0 cm in diameter with exposed bones covered with or without periosteum were created at the parietal regions in 88 rabbits that were further randomly divided into the following treatment groups: periosteum-intact wounds treated with conventional vaseline gauze dressings (P + Control group), periosteum-intact wounds treated with NPWT (P + NPWT group), periosteum-lacking wounds treated with conventional vaseline gauze dressings (P-Control group), and periosteum-lacking wounds treated with NPWT (P-NPWT group)...

The effects of responding to social pressure (external motivation) are short-lived. Multicultural training, however, seeks to promote change in students and trainees that will be transformative and long-lasting. To this end, understanding the motivational factors that inform training is key. The present study was an investigation of the factors underlying external motivation to respond without prejudice for White individuals from the perspective of Higgins's regulatory focus (promotion and prevention) and regulatory mode (assessment and locomotion) theories...

BACKGROUND: Impaired intestinal motility may lead to the disruption of gut microbiota equilibrium, which in turn facilitates bacterial translocation (BT) and endotoxemia in cirrhosis. We evaluated the influence of mosapride, a prokinetic agent, on BT and DNA fingerprints of gut microbiota in cirrhotic rats. METHODS: A rat model of cirrhosis was set up via subcutaneous injection of carbon tetrachloride (CCl4). The portal pressure, liver and intestinal damage, plasma endotoxin, BT, and intestinal transit rate (ITR) of cirrhotic rats were determined...

The architectural integrity of tissues requires complex interactions, both between cells and between cells and the extracellular matrix. Fundamental to cell and tissue homeostasis are the specific mechanical forces conveyed by the actomyosin cytoskeleton. Here we used super-resolution imaging methods to visualize the actin cytoskeleton in the kidney glomerulus, an organized collection of capillaries that filters the blood to make the primary urine. Our analysis of both mouse and human glomeruli reveals a network of myosin IIA-containing contractile actin cables within podocyte cell bodies and major processes at the outer aspects of the glomerular tuft...

Global stressors, such as ocean acidification, constitute a rapidly emerging and significant problem for marine organisms, ecosystem functioning and services. The coastal ecosystems of the Humboldt Current System (HCS) off Chile harbour a broad physical-chemical latitudinal and temporal gradient with considerable patchiness in local oceanographic conditions. This heterogeneity may, in turn, modulate the specific tolerances of organisms to climate stress in species with populations distributed along this environmental gradient...

BACKGROUND: Speckle-type POZ protein (SPOP) is an E3 ubiquitin ligase adaptor protein that functions as a potential tumor suppressor, and SPOP mutations have been identified in ~10% of human prostate cancers. However, it remains unclear if mutant SPOP proteins can be utilized as biomarkers for early detection, diagnosis, prognosis or targeted therapy of prostate cancer. Moreover, the SPOP mutation sites are distributed in a relatively short region with multiple lysine residues, posing significant challenges for bottom-up proteomics analysis of the SPOP mutations...
