BACKGROUND The effects of chronic exercise training on myocardial contractility and beta-adrenergic signal transduction in hearts with left ventricular dysfunction have not been determined. METHODS AND RESULTS Fourteen-week-old cardiomyopathic BIO 53.58 and normal F1B Syrian hamsters underwent 10 weeks of treadmill training and were compared with 24-week-old BIO 53.58 and F1B untrained contro...

Pyrolitic conversion of lignocellulosic biomass, such as switchgrass and other agricultural residues, to bio-fuels is being considered for national energy security and for environmental advantages. Bio-oil, syngas and bio-char were produced and characterized from switchgrass at 400, 500 and 600 0C by pyrolysis. Bio-oil yield increased from 22 to 37%, syn-gas yield increased from 8 to 26%, and b...

Effects of bio-nitrogen fertilizer (bio-N), as a partial alternative to mineral-nitrogen fertilizer (mineral-N), on growth, yield and yield quality of broccoli plants were investigated. Bio-N was applied at 1, 2 or 3 doses in combination with 65% of the recommended dose of mineral-N (bio-N1, bio-N2 or bio-N3 + 2⁄3mineral-N). However, 100% of the recommended dose of mineralN was applied as a con...

This article overviews the enzymes produced by microorganisms, which have been extensively studied worldwide for their isolation, purification and characterization of their specific properties. Researchers have isolated specific microorganisms from extreme sources under extreme culture conditions, with the objective that such isolated microbes would possess the capability to bio-synthesize spec...

What is the value of bio-objects? In a series of texts (primarily published in the Croatian Medical Journal) new entities, identified and/or produced by new technology, have been analytically defined as bio-objects. Bio-objects derive from innovative knowledge, they are generated through a “bio-objectification” process, and continuously negotiated in the intersection of science, politics, and s...

in order to determine the effects of applied phosphate bio-fertilizer on yield and morphological traits of wheat, a research was conducted in sari agricultural sciences and natural resources university during 2008-2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio-fertilizer (0 and...

The recovery of clean energy in the form of methane-containing biogas is starting to receive tremendous attention in South Africa. However, it is unclear whether the transition from standard bio-methane production to waste-based bio-hydrogen production would improve or worsen the environmental and energetic performance as quantified by Life Cycle Assessment (LCA). The results of this study show...
