The presence of biologically active compounds in the neuronal tissues of the mango leaf webber, O. exvinacea that can influence lipid, carbohydrate and protein metabolism were investigated. The activity of the brainretrocerebral complex extract tested in vivo in the polyphagous plant bug, Iphita limbata (heterologous bioassay) revealed that the extract and also the synthetic peptide, Locmi-AKH-...

a bivoltine silkworm hybrid, ka x nb4d2 was treated with the juvenoid r394 (ethyl-9 cyclohexyl-3,7-dimethyl-2,4-nonadienoate) at a dose of 0.039 nl/larva at 24, 48, 72 and 96 h of 5th instar for silk yield improvement. treatment specific significant increase was observed in the cocoon and shell weight with no such marked variation in the shell percentage. notable changes were also seen in trait...

The 'adaptive modulation hypothesis' predicts that activity of digestive enzymes should match the amount of their substrates in diet. Interestingly, many passerine birds do not adjust the activity of intestinal carbohydrases to dietary carbohydrate content. It is difficult to assess the generality of this rule, because in some studies passerines fed on low-carbohydrate and high-lipid diet showe...

objective: type 2 diabetes mellitus is a complex metabolic disorder with adverse cardiovascular risk. chromium (cr) is an essential nutrient and its role in carbohydrate and lipid metabolism has not been clarified especially in iran. the aim of this study was to evaluate the effect of chromium picolinate administration on blood glucose, hba1c, lipid profile and lipid peroxidation in type 2 diab...

A st act.—During migration, many songbirds eat primarily fruit while depositing fat. Given that some fruits contain mostly carbohydrate and others contain mostly lipid, the ability of birds to fatt en may depend on the macronutrient composition of the fruit. Stable isotopes of carbon may be useful in determining the source of nutrients used for synthesizing fat, because the enzyme that regulate...

A bivoltine silkworm hybrid, KA x NB4D2 was treated with the juvenoid R394 (Ethyl-9 cyclohexyl-3,7-dimethyl-2,4-nonadienoate) at a dose of 0.039 nl/larva at 24, 48, 72 and 96 h of 5th instar for silk yield improvement. Treatment specific significant increase was observed in the cocoon and shell weight with no such marked variation in the shell percentage. Notable changes were also seen in tr...

The polypeptide, lipid, and carbohydrate components of the lipovitellin complex from anostracan crustacean, Artemia salina, have been investigated. The lipovitellin isolated from the yolk granules is a carotenoid.lipoglycoprotein complex, containing 3.3% carbohydrate and 8.6% lipid. About half of the carbohydrate fraction is mannose and the rest consists of galactosamine, galactose, and glucosa...

Lipid fractions obtained from Mycobacterium avium serovar 8 were assessed for the ability to affect various immune functions of human peripheral blood mononuclear cells (PBM). Lipids included a total lipid fraction and fractions eluted from silicic acid column separation of that total lipid fraction, using chloroform and chloroform-methanol combinations. Lipid fractions were assayed for total c...
