In this study, the vitamin D3 plus nicotine (VDN) model of rats was used to prove that H2S alleviates vascular calcification (VC) and phenotype transformation of vascular smooth muscle cells (VSMC). Besides, H2S can also inhibit endoplasmic reticulum stress (ERS) of calcified aortic tissues. The effect of H2S on alleviating VC and phenotype transformation of VSMC can be blocked by TM, while PBA...

The study aims to examine information seeking and sharing behavior of IT professionals in a virtual community (VC). In total, 200 threads with 1623 postings were extracted from ChinaUnix.net, an IT VC. A content analysis was performed and descriptive statistical analysis was conducted. The study identified four types of information seeking and sharing activities: resource sharing, experience sh...

Arterial baroreflex is a general mechanism maintaining cardiovascular homeostasis; its sensitivity is reduced in vascular calcification (VC). Hydrogen sulfide (H2S) treatment facilitates baroreflexive sensitivity in normal and hypertensive rats. Here, we aimed to detect the effect of H2S on baroreflexive sensitivity in rats with VC. The rat VC model was induced by vitamin D3 plus nicotine for 4...

Field Editor: Dimo Dimov This article analyses whether and how the impact of publicly backed venture capital (VC) funds varies across regions, depending on their level of innovation intensity and in comparison with private VC funds. Building on agency and human capital theories, the authors distinguish public VC funds into regional and governmental types, to assess potential differences in the ...

Vinyl chloride (VC) disease is a multisystem disorder incorporating Raynaud's phenomenon, acro-osteolysis, thrombocytopenia, portal fibrosis, and hepatic and pulmonary dysfunction. Immunological and immunochemical investigations showed the presence of circulating immune complexes in 19 out of 28 patients with the disease and in a further two out of 30 workers exposed to VC. The immunological da...

I develop a model of venture capital (VC) intermediation that can quantitatively explain central empirical facts about VC activity and allows evaluating its impact on economic growth. The framework reveals how pro-cyclical VC investment dynamics reinforce themselves through a risk premium channel that rationalizes low funding standards in booms. VC investments’ aggregate impact is significantly...

Variance-component (VC) methods are flexible and powerful procedures for the mapping of genes that influence quantitative traits. However, traditional VC methods make the critical assumption that the quantitative-trait data within a family either follow or can be transformed to follow a multivariate normal distribution. Violation of the multivariate normality assumption can occur if trait data ...

BACKGROUND AND OBJECTIVES Vascular calcification (VC) contributes to increased cardiovascular (CV) disease in dialysis patients and is inversely correlated with bone mineral density (BMD). Screening for VC may determine patients at greater CV risk and bone densitometry may have dual role in assessing VC as well as BMD. The aim of this study was to determine measurement of VC using dual-energy x...

OBJECTIVE To determine whether optoelectronic plethysmography accurately evaluated vital capacity (VC) in patients with respiratory muscle dysfunction of variable severity, including those with paradoxical abdominal movements. METHODS In 20 subjects, VC was measured in the supine position using both spirometry and optoelectronic plethysmography (6 optoelectronic cameras and 52 reflective mark...

This paper reports results related to the phenomenon referred to as a “glottal squeak” (coined by [1]). At present, nothing is known about the conditioning and the articulation of this feature of speech. Our qualitative acoustic analyses of the conditioning of squeaks (their frequency of occurrence, duration, and f0) found in Aberystwyth English and Manchester English suggest that squeaking may...
