Honeybees and bumblebees are the most important pollinators of agricultural crops. For this purpose honeybees and bumblebees are reared and transported. A pathogen-free status of bees in general, is crucial. Indeed anthropogenic transports of hosts carrying parasites could alter the natural host/pathogen association, inducing an extra pathogenic stress. Therefore the ...

Wild mushrooms are an excellent source of vitamin D. The presence of vitamin D in mushrooms is attributed to sunlight exposure, which catalyzes the conversion of fungal ergosterol to vitamin D2via a series of photochemical/thermal reactions. Mushroom growers now incorporate UV light treatments during processing to produce mushrooms with levels ...

Autoantibodies reacting with alpha-melanocyte-stimulating hormone (α-MSH), an anorexigenic neuropeptide, are involved in regulation of feeding. In this work we studied if intestinal inflammation (mucositis) may influence α-MSH autoantibodies production relevant to food intake and body weight. Mucositis and anorexia were produced in Sprague-Dawley rats by methotrexate (MTX, 2.5mg/kg/day, for three ...

Evidence suggests that release of oxytocin in the nucleus tractus solitarius (NTS) of the hindbrain from descending projections that originate in the paraventricular nucleus can inhibit food intake by amplifying the satiety response to cholecystokinin (CCK). To further evaluate this mechanism in rats, we used a novel cytotoxin, saporin conjugated ...

Food intake is regulated by signals from peripheral organs, but the way these are integrated remains uncertain. Cholecystokinin (CCK) from the intestine and leptin from adipocytes interact to inhibit food intake. Our aim was to examine the hypothesis that these interactions occur at the level of vagal afferent neurons via ...

Estrogens have potent suppressive effects on food intake and body weight in many species, including humans. Compelling evidence suggests estrogen's anorectic action is through an indirect mechanism by enhancing the strength of other physiological signals that reduce meal size such as apolipoprotein A-IV (apo A-IV), a satiation factor from the ...

Glycomacropeptide (GMP) is the hydrophilic 64-amino acid C-terminal glycopeptide released into cheese whey when kappa-casein is cleaved by chymosin. GMP exists as a mixture of different glycoforms due to the carbohydrates sialic acid (N-acetylneuraminic acid, NeuNAc), galactose (Gal), galactosamine and glucosamine attached by O-glycosidic linkages. GMP reportedly stimulates the release ...

Cholecystokinin (CCK) acutely synergizes with amylin to suppress food intake in lean mice. To extend on these findings, the present studies sought to identify neural correlates for the interaction of amylin and CCK, as well as further understand the therapeutic potential of CCK-based combinations in obesity. First, c-Fos activation was ...

BACKGROUND & AIMS: In human beings, as in most vertebrates, the release of the intestinal peptide cholecystokinin (CCK) by ingested food plays a major role both in digestion and the regulation of further food intake, but the changes in brain function and their underlying activation mechanisms remain unknown. Our aim ...
