OBJECTIVE To evaluate the larvicidal and pupicidal potential of the methanolic extracts from Moringa oleifera (M. oleifera) plant seeds against malarial vector Anopheles stephensi (A. stephensi) mosquitoes at different concentrations (20, 40, 60, 80 and 100 ppm). METHODS M. oleifera was collected from the area of around Bharathiar University, Coimbatore. The dried plant materials were powdere...

BACKGROUND The aim of this study was to investigate the incidence and immediate and mid-term effects of heart valve prosthesis-patient mismatch (PPM) after mitral valve replacement using the GK bileaflet mechanical valve. MATERIAL AND METHODS A total of 493 cases of mechanical mitral valve replacement were performed in the departments of cardiac surgery in 7 hospitals from January 2000 to Jan...

First, the developmental toxic potential of n-butyl acetate (BA) was examined in SpragueDawley rats following whole body inhalation exposure, 6 h day-1, from day 6 to 20 of gestation, at concentrations of 0, 500, 1000, 2000 and 3000 ppm. Maternal toxicity was evidenced by significant decreases in body weight gain at 2000 and 3000 ppm, and by reduced food consumption at 1000 ppm and higher conce...

Acute and Subchronic Inhalation Toxicity of Chloroform in Rats and Mice: Tatsuya KASAI, et al. Japan Bioassay Research Center—In order to better characterize acute and subchronic toxicities of chloroform and to provide its basic toxicity data for risk assessment of humans exposed to chloroform in work and living environments, mice and rats of both sexes were exposed by inhalation to chloroform ...

BACKGROUND The prosthesis used for aortic valve replacement (AVR) can be too small in relation to body size, thus causing valve prosthesis-patient mismatch (PPM) and abnormally high transvalvular pressure gradients. This study examined if there is a relation between PPM and short-term mortality after operation. METHODS AND RESULTS The indexed valve effective orifice area (EOA) was estimated f...

Introduction Patient-prosthesis mismatch (PPM) is relatively frequent after surgical aortic valve replacement (SAVR) and negatively impacts prognosis. Aim We sought to determine the frequency and clinical effects of PPM after transcatheter aortic valve implantation (TAVI). Material and methods Overall, 238 patients who underwent TAVI were screened. Moderate PPM was defined as indexed effect...

BACKGROUND Combined aortic valve replacement and coronary revascularisation is becoming more frequent. Patient-prosthesis mismatch (PPM) as an additional risk factor may potentially affect the early and late outcome. AIM To evaluate the impact of PPM on early and mid-term clinical results including quality of life in patients undergoing combined surgical treatment of coronary artery disease a...

The independent contributions of formula and water to the total fluoride (F) intake from the diet of formula-fed infants is not fully documented. Although the precise timing and mechanism by which dental fluorosis occurs has not been fully defined, water F levels can be an important consideration in the risk of dental fluorosis for formula-fed infants. An assessment of 1,308 participants younge...
