Pulmonary arterial hypertension (PAH) is a syndrome in which pulmonary arterial obstruction increases pulmonary vascular resistance (PVR) leading to right ventricle (RV) failure. Progression and survival of patients with PAH are related to the ability of the RV to adapt to the chronically elevated pulmonary artery pressure (PAP), 1) hence, RV function is an important determinant of prognosis in...

Since systemic sclerosis (SSc) also involves the heart, the aim of the present study was to evaluate possible differences in right ventricular (RV) pump function between SSc-associated pulmonary arterial hypertension (PAH; SScPAH) and idiopathic PAH (IPAH). In 13 limited cutaneous SScPAH and 17 IPAH patients, RV pump function was described using the pump function graph, which relates mean RV pr...

To produce fish of a high quality that are rich in omega-3 fatty acids (n-3 FA) and simultaneously generate more sustainable aquaculture, the combined use of phytochemicals and vegetable oils in fish feed seems to be a promising approach. Resveratrol (RV) potentially induces endogenous fatty acid synthesis, resulting in elevated n-3 FA levels in fish. RV putatively influences ∆6-desaturase, the...

BACKGROUND Although proximal right coronary artery (RCA) occlusion is the culprit commonly responsible for acute right ventricular (RV) infarction (RVI), the severity of RV dysfunction ranges broadly. This study was designed to delineate the patterns of coronary compromise that determine the magnitude of RV ischemic dysfunction. METHODS AND RESULTS In 125 patients with acute inferior myocardi...

BACKGROUND Pulmonary hypertension (PH) causes elevated right ventricular (RV) systolic pressure, RV remodeling and finally RV failure to death. However, the mechanisms of RV remodeling in PH remain to be fully elucidated. METHODS AND RESULTS RV autopsy samples from 6 PH patients with RV failure against 3 age- and sex-matched controls were first examined. Next, RV remodeling in 2 mouse models ...

Rhinovirus-(RV-) induced asthma exacerbations account for high asthma-related health costs and morbidity in Australia. The cellular mechanism underlying this pathology is likely the result of RV-induced nuclear-factor-kappa-B-(NF-κB-) dependent inflammation. NF-κB may also be important in RV replication as inhibition of NF-κB inhibits replication of other viruses such as human immunodeficiency ...

A newly invented compressor, namely revolving vane compressor (RV) has been introduced two years ago (Teh and Ooi, 2006, 2006, 2006). This paper presents the improved version (Teh and Ooi, 2007) of the RV, called RV-i, where “i” stands for improved. The RV or RV-i is designed with the intention to overcome most of the limitations facing the working characteristics of the rolling piston compress...

Abstract Funding Acknowledgements Type of funding sources: None. Background. Functional Tricuspid Regurgitation (FTR) has been described as a common condition after isolated mitral valve (MV) surgery, affecting patients’ prognosis. Thus, in cases without significant tricuspid regurgitation (TR) but annular (TA) dilatation, TV annuloplasty is currently recommended. Studies suggesting the used cu...

Background/Aims: It has previously been shown that permanent right ventricular (RV) apical pacing may lead to worsening of cardiac function due to associated electrical and mechanical dyssynchrony. Cardiac resynchronization therapy (CRT) or high septal RV pacing could be beneficial to prevent patients from these negative effects. Methods/Results: In this single center clinical study 164 patient...

OBJECTIVES To evaluate the contribution of breastfeeding to Rotavirus (RV)-induced antigenemia and/or RNAemia and disease severity in Indian children (<2 yrs age). METHODS Paired stool and serum samples were collected from (a) hospitalized infants with diarrhea (n = 145) and (b) healthy control infants without diarrhea (n = 28). Stool RV-antigen was screened in both groups by commercial rapid...
