A cinnamoyl esterase, ferulic acid esterase A, from Aspergillus niger releases ferulic acid and 5-5- and 8-O-4-dehydrodiferulic acids from plant cell walls. The breakage of one or both ester bonds from dehydrodimer cross-links between plant cell wall polymers is essential for optimal action of carbohydrases on these substrates, but it is not known if cinnamoyl esterases can break these cross-li...

Effect of genistein, a protein tyrosine kinase inhibitor, on TAME-esterase induced contractions were studied on rat aorta strips in vitro. Data showed that TAME-esterase induced contractions were concentration dependent and these contractions were significantly inhibited when rat aorta strips were pre-incubated with genistein. The present findings provide evidence for the possible contribution ...

BACKGROUND The presence of leukocyte esterase in the synovial fluid has recently been proposed as a marker for periprosthetic joint infection. However, the sensitivity and specificity of leukocyte esterase has not been determined when matched for the current, most inclusive Musculoskeletal Infection Society (MSIS) criteria for periprosthetic joint infection. METHODS The presence of leukocyte ...

A patient with apparent X-linked agammaglobulinaemia was found to be inordinately susceptible to anaphylactoid reactions to intramuscular injections of gammaglobulin. The patient was found also to have low levels of C1 esterase inhibitor (C1 INH). The possibility that the C1 INH deficiency and in this patient, whether genetic or acquired, fostered the susceptibility to the production of anaphyl...

Background: Gold standard for the diagnosis of urinary tract infections (UTIs) is urine culture, but it takes longer bacterial growth on culture media. Leukocyte esterase a simple strip testing sample, so less time in diagnosing cases UTI. Objective: To determine diagnostic accuracy leukocyte detection infection children taking as gold standard. Materials and Methods: This cross-sectional study...

Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life-like materials, we compartmentalized urea-urease more complex urea-urease/ester-esterase pH-feedback into hydrogel spheres investigate how fuel-driven pH fronts can be sent out from these regulated by internal networks. Membrane characterist...

Interaction of Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 Race 3 with javanica (Treub, 1885) in Tomato and Pepper
 
 More than one species root-knot nematodes can attack field vegetables they interact each other. In this study, the interaction race M. on susceptible host plants (Falkon Sena) were investigated a growth room fully controlled conditions. Experiments ...

BACKGROUND Delirium is common in ill medical patients. Several drugs and polypharmacy are recognised risk factors, yet little is known about drug metabolism in people with delirium. OBJECTIVE The aim of this study was to investigate the activities of plasma esterases (drug metabolising enzymes) in delirium. DESIGN This was a prospective study of delirium present at time of hospital admissio...

The possibility that some factor in serum changes the substrate specificity of purified human plasma carboxyl esterase, which hydrolyzes the short chain fatty acid ester, tributyrin, was investigated. The purified carboxyl esterase from human plasma hydrolyzed 48 mmol of tributyrin/mg of protein/h, monoolein at 1560 mumol of released fatty acids/mg of protein/h, diolein at 133 mumol of released...

Proteins in the serine esterase family are widely distributed in bacterial phyla and display activity against a range of biologically produced and chemically synthesized esters. A serine esterase from the psychrophilic bacterium Pseudoalteromonas arctica with a C-terminal OsmC-like domain was recently characterized; here we report on the identification and characterization of further putative e...
