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...

Paints with high lead concentrations (ppm) continue to be sold around the world in many developing countries and those with economies in transition representing a major preventable environmental health hazard that is being increased as the economies expand and paint consumption is increasing. Prior lead paint testing had been performed in Brazil and India and these countries were selected to ex...

Static bioassays were performed to observe the toxic effect of malathion to Barbodes gonionotus at 0.0 to 20.0 ppm concentrations. Malathion at 5.0 ppm was harmless to B. gonionotus and concentration above 6.0 ppm were found to be lethal. Malathion at 2.06 ppm was safe for the B. gonionotus.

Twelve fractions from chloroform extract of Clerodendrum phlomidis and 5,7-dihydroxy4,6-dimethoxy-flavone (pectolinaringenin) were evaluated against Helicoverpa armigera. Maximum antifeedant (89.41%), larvicidal (83.77%) and ovicidal (69.25%) activities were observed in fraction 5. The least LC50 value for antifeedant (178.09 ppm) and larvicidal (198.23 ppm) were observed in fraction 5. No adu...

Recently, there has been an emphasis on managing projects strategically within the organization using project portfolio management (PPM). However, the extent of adoption of this innovation and the enabling factors are not well understood in academics and practice. This research-inprogress investigates a model of PPM adoption using data being collected from project managers. The model identifies...

BACKGROUND AND PURPOSE Metabolites in pyogenic brain abscesses, as detected with in vivo proton MR spectroscopy, are different from those found in brain and can help differentiate pyogenic brain abscesses from necrotic neoplasms. We compared the findings of in vivo with those of in vitro MR spectroscopy and categorized the MR spectral patterns with respect to the causative organisms and abscess...

The possible protective effect of a feed additive (Mycofix) against the toxic effects of 4,15-diacetoxiscirpenol (DAS) in growing broiler chickens was investigated in a 21-d fully randomized trial consisting of seven dietary treatments (control with no DAS or Mycofix added, 1 ppm DAS alone, 1 ppm DAS supplemented with 0.75 g/kg Mycofix, 1 ppm DAS supplemented with 1.5 g/kg Mycofix, 2 ppm DAS al...
