pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...
in the present study an attempt has been made to use a non-parametric method data envelopment analysis (dea) for assessing source-wise and operation-wise the technical efficiency (te) and return-to-scale (rts) for paddy production in four zones of the state of punjab, india. the results were then compared to corresponding ones already obtained from a parametric method (cobb-douglas production f...
The fabrication of novel systems where enzymatic and metallic actives sites can be directly interacting represent a very fancy strategy for sustainable processes. One the new strategies goes to direct formation metal nanoparticles in situ on protein network as scaffold. This biological entity is key element because conserved its catalytic efficiency but induced final generation their structure....
3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMG CoA reductase) controls the rate of cholesterol biosynthesis and is itself modulated through feedback suppression by internalized low density lipoprotein (LDL) cholesterol. We measured HMG CoA reductase protein concentration and microsomal enzyme activity in freshly isolated mononuclear leukocytes from normal individuals and patients with het...
Human cytosolic sulfotransferases (SULTs) regulate the activities of thousands of small molecules-metabolites, drugs, and other xenobiotics-via the transfer of the sulfuryl moiety (-SO3) from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to the hydroxyls and primary amines of acceptors. SULT1A1 is the most abundant SULT in liver and has the broadest substrate spectrum of any SULT. Here we presen...
The effects of subsite interactions in the S2-S4 region [Schechter & Berger (1967) Biochem. Biophys. Res. Commun. 27, 157-162] of porcine pancreatic kallikrein (EC 3.4.21.8) on its catalytic efficiency have been investigated. Kinetic constants (Kcat, Km) have been determined for a series of seven extended N-aminoacyl-L-arginine methyl esters whose sequence is based on either the C-terminal sequ...
universities of medical science and health services (umshss) are among the main organizations in iran's health-care section. improving their efficiency in financial resource management through creating an appropri-ate coordination between consumption and resources is strategically vital. investigating the financial performance as well as ranking the iranian umshss is the research objective.the ...
Cocaine is one of the most addictive drugs, and there is still no FDA (Food and Drug Administration)-approved medication specific for cocaine abuse. A promising therapeutic strategy is to accelerate cocaine metabolism, producing biologically inactive metabolites via a route similar to the primary cocaine-metabolizing pathway, i.e. cocaine hydrolysis catalyzed by butyrylcholinesterase (BChE) in ...
Human manganese superoxide dismutase is a mitochondrial metalloenzyme that is involved in protecting aerobic organisms against superoxide toxicity, and has been implicated in slowing tumor growth. Unfortunately, this enzyme exhibits strong product inhibition, which limits its potential biomedical applications. Previous efforts to alleviate human manganese superoxide dismutase product inhibition...
Enzymatic modification of foods is an important tool for enhancing starch functionality due to its safety, high efficiency, and specificity. gelatinized systems well reported in literature. However, our knowledge, a review describing comparing the effects granular vs. enzyme-assisted both timely lacking. We summarize, discuss point at future aspects consequences using various techniques enzymat...
