This research aimed to evaluate the effect of use microwaved flaxseed flour as broiler feed on growth performance and digestive enzyme activity. The material used was 200 a-day-old chicks strain Lohmann MB Platinum. method this in vivo feeding trial using a Completely Randomized Design (CRD) with 5 treatments 4 replications. included levels 0% (T0), 2.5% (T1), 5% (T2), 7.5% (T3), 10% (T4). vari...

OBJECTIVE To investigate the association between the gene polymorphisms of angiotensin-converting enzyme (ACE) and digestive system cancer risk. METHOD A search was performed in Pubmed, Medline, ISI Web of Science and Chinese Biomedical (CBM) databases, covering all studies until Sep 1st, 2013. Statistical analysis was performed by using Revman5.2 and STATA 12.0. RESULTS A total of 15 case-...

The spindles of Anomala cuprea entomopoxvirus (AncuEPV), which are composed of glycoprotein fusolin, are known to enhance the peroral infectivity of AncuEPV itself and of nucleopolyhedroviruses. This has been demonstrated to involve the disruption of intestinal peritrophic membrane (PM), composed of chitin matrix, glycosaminoglycans, and proteins. To identify essential and nonessential regions ...

Background and Aims: Human lymphotropic virus type-1 (HTLV-1) causes various diseases such as adult T-cell leukemia/lymphoma (ATLL) and HTLV-1 associated myelopathy/tropical spastic paraperesis (HAM / TSP) in humans. The main goal of this study is to compare Iranian protease subtypes structure of this virus (HTLV-1) to samples collected from other part of world in order to understand their diff...

Digestive systems of deposit and suspension feeders can be exposed to high concentrations of copper (Cu) by ingestion of contaminated sediments. We assessed a potential impact of this Cu exposure on digestive enzyme activities in a wide range of benthic organisms by monitoring enzyme activities in their gut fluids during in vitro titrations with dissolved Cu, which mimics Cu solubilization from...

The intertidal mussel Mytilus californianus is a critical foundation species that is exposed to fluctuations in the environment along tidal- and wave-exposure gradients. We investigated feeding and digestion in mussels under laboratory conditions and across environmental gradients in the field. We assessed whether mussels adopt a rate-maximization (higher ingestion and lower assimilation) or a ...

Structures of the complexes of HIV protease inhibitor L--756,423 with the HIV-1 wild-type protease and of the inhibitors Indinavir, L-739,622 and Saquinavir with the mutant protease (9X) containing nine point mutations (Leu10Val, Lys20Met, Leu24Ile, Ser37Asp, Met46Ile, Ile54Val, Leu63Pro, Ala71Val, Val82Thr) have been determined. Comparative analysis of these structures reveals an alternate bin...

M1 myeloid leukemic cells overexpressing wild-type p53 undergo apoptosis. This apoptosis can be suppressed by some cytokines, protease inhibitors, and antioxidants. We now show that induction of apoptosis by overexpressing wild-type p53 is associated with activation of interleukin-1beta-converting enzyme (ICE)-like proteases, resulting in cleavage of poly(ADP- ribose) polymerase and the proenzy...

Type IV fimbriae are essential virulence factors of Dichelobacter nodosus, the principal causative agent of ovine foot rot. The fimA fimbrial subunit gene is required for virulence, but fimA mutants exhibit several phenotypic changes and it is not certain if the effects on virulence result from the loss of type IV fimbria-mediated twitching motility, cell adherence, or reduced protease secretio...
