Recent work has demonstrated that inhibition of nitric oxide production with various nitric oxide synthesis inhibitors (L-NAME, L-NMMA) initiate leukocyte adhesion to postcapillary venules. The objective of this study was to elucidate the mechanism (or mechanisms) that promote the L-NAME-induced leukocyte response. Intravital microscopy was used to examine 25-40 microns venules in the rat mesen...

Seasonal allergic conjunctivitis is an illness which decreases quality of life and is common in society. Pharmacoeconomic evaluation about seasonal alergic conjunctivitis has not been measured in Turkey. The aim of our study is to understand the cost-effective medicines which are used for seasonal allergic conjunctivitis with Turkish data. In our study, effectiveness data from randomized contro...

Escherichia coli produces two enzymes which interconvert succinate and fumarate: succinate dehydrogenase, which is adapted to an oxidative role in the tricarboxylic acid cycle, and fumarate reductase, which catalyzes the reductive reaction more effectively and allows fumarate to function as an electron acceptor in anaerobic growth. A glycerol plus fumarate medium was devised for the selection o...

Oxidation of succinate to fumarate is an energetically difficult step in the biochemical pathway of propionate oxidation by syntrophic methanogenic cultures. Therefore, the effect of fumarate on propionate oxidation by two different propionate-oxidizing cultures was investigated. When the methanogens in a newly enriched propionate-oxidizing methanogenic culture were inhibited by bromoethanesulf...

The effects of sodium cromoglycate and ketotifen were studied in a group of 20 patients in whom fish repeatedly provoked an attack of wheezing and dyspnoea within one hour of its being eaten. Fish ingestion resulted in a fall in forced expiratory volume in one second (FEV1) of at least 15%. All patients had a weal greater than 4 mm in response to fish antigen in the skinprick test and most had ...

The filamentous fungus Rhizopus delemar naturally accumulates relatively high amounts of fumarate. Although the culture conditions that increase fumarate yields are well established, the network underlying the accumulation of fumarate is not yet fully understood. We set out to increase the knowledge about fumarate accumulation in R. delemar. To this end, we combined a transcriptomics and proteo...
