pistachio green stink bug, acrosternum hegeeri, due to its inflicting damages on crop quantity and quality, is of a great economical importance in pistachio production. on the other hand, a knowledge of digestive enzymes, is quite indispensable in the study and application of new pest management technologies. results of studeies have shown that midgut in this insect is divided into four section...

the impact of three different fabaceous host plants including cowpea (vigna unguiculata), chickpea (cicer arietinum), and mung bean (vigna radiata) seeds was investigated using biochemical approaches on possible changes of gut proteolytic activity of the cowpea weevil, callosobruchus maculatus at 30±1˚c and 70±5% rh and a photoperiod of 8:16 (l:d). results revealed that ph of 4-5 and 9 was opti...

BACKGROUND Celiac disease is a T cell mediated-inflammatory enteropathy caused by the ingestion of gluten in genetically predisposed individuals carrying HLA-DQ2 or HLA-DQ8. The immunogenic gliadin epitopes, containing multiple glutamine and proline residues, are largely resistant to degradation by gastric and intestinal proteases. Salivary microorganisms however exhibit glutamine endoprotease ...

The chemical synthesis of N-alpha-benzyloxycarbonyl-L-lysine p-nitroanilide (Z-Lys-pNA) is described in detail. The pH-dependence of the catalytic parameters kcat,' Km and kcat./Km for the papain-catalysed hydrolysis of Z-Lys-pNA are determined. kcat. and Km are pH-independent between pH 5 and pH 7.42, but the pH-dependence of kcat./Km is bell-shaped, decreasing at high and low pH values with p...

1.2. Proposition. — π : PnA → SpecA is a closed morphism. Proof. Suppose Z ↪→ PnA is a closed subset. We wish to show that π(Z) is closed. Suppose y / ∈ π(Z) is a closed point of SpecA. We’ll check that there is a distinguished open neighborhood D(f) of y in SpecA such that D(f) doesn’t meet π(Z). (If we could show this for all points of π(Z), we would be done. But I prefer to concentrate on cl...

Histochemical studies have shown a decreased concentration of cytoplasmic pentose nucleic acid1 in the liver (l-4)) pancreas (2), spinal cord (3), and cervical ganglia (3) of vitamin Blz-deficient rats. The concentration of both PNA and DNA per gm. of tissue was decreased in livers from weanling rats fed a diet containing iodinated casein, but the amount per cell was unchanged (5, 6). Compariso...
