Modeling fish growth to predict fish production is important for planning of aquaculture development. Since growth strongly depends on feed intake, a growth model should be able to predict maximum feed intake of the fish under ad libitum feeding. However, the equations for maximum feed intake in the existing fish growth models are still descriptive and do not reflect the underlying mechanisms r...

The role of the ghrelin--obestatin system in health and disease is multifaceted and new ample evidence has been recently accumulated. Ghrelin was discovered much earlier than obestatin so the biological, physiological and pathophysiological, pharmacological aspects of its activity could be studied far better than obestatin. There is no question that these hormones are not antagonists and they a...

Abstract Telescopic water intake structures play an important role in a management system. The article is devoted to the improvement of telescopic and development solution for regulating their operation. Different types intakes are analyzed, shortcomings identified. known reviewed, operating principles analyzed. It has been determined that design existing lacks device stopping operation water. ...

Mammals that hibernate (hibernators) exhibit a circannual rhythm of food intake and body mass. In the laboratory during the winter hibernation period, many hibernators enter a series of multi-day torpor bouts, dropping their body temperature to near ambient, and cease to feed even if food is present in their cage. The mechanism(s) that regulates food intake in hibernators is unclear. Recently, ...

OBJECTIVE Preclinical studies indicate that oxytocin is anorexigenic and has beneficial metabolic effects. Oxytocin effects on nutrition and metabolism in humans are not well defined. It was hypothesized that oxytocin would reduce caloric intake and appetite and alter levels of appetite-regulating hormones. Metabolic effects of oxytocin were also explored. METHODS A randomized, placebo-contro...

The debate on the effect of trade liberalization food security poses solid arguments, both in favor as well against issue. This study aims to analyze linkages between (measured using import tariff exposure) and nutrition intake) case Indonesia. national is decomposed into district-level exposure analyzed based sectoral tariffs such agriculture manufacture tariffs. analysis employs panel data 49...
