The etiology of altered blood fatty acid (FA) composition in cystic fibrosis (CF) is understood only partially. We aimed to investigate the determinants of serum glycerophospholipids' FAs in CF with regard to the highest number of FAs and in the largest cohort to date. The study comprised 172 CF patients and 30 healthy subjects (HS). We assessed Fas' profile (gas chromatography/mass spectrometr...

1. The prostaglandin precursor arachidonic acid (C20:4) increases plasma renin activity in the rabbit and rat when it is infused into the renal arteries. 2. The increase in plasma renin activity after C20:4 in rats is not changed by volume expansion. 3. The inhibitor of prostaglandin synthesis indomethacin decreases plasma renin activity in the rabbit. 4. The increase plasma in renin activity a...

Aggregation properties of gangliosides, the major synaptic membrane glycosphingolipids of mammalian brain, may prevent their segregation during membrane assembly and promote a uniform membrane matrix with minimum maintenance energy. The sphingosine residues of bovine brain gangliosides show an increase in C20-sphingosine corresponding with an increase in sialic acid. Concentrations of C20-sphin...

Atomic absorption spectrophotometery showed significant levels of contamination by Cd, Hg, Cu, Mn, Zn, Pb, Cr and Sn in fish habitats. Fatty acids from meat were detected by gas chromatography. C12:0, C20:0, C16:1(n-7), C16:1(n-9), C18:1(n-9), C20:1(n-9), C18:2(n-6), C18:4(n-3), C22:4(n-6), C20:5(n-3) and C22:4(n-6) fatty acids were found missing in fish obtained from area of higher pollution w...

The objective of this study was to evaluate the effect of ambient temperature and sodium bicarbonate (NaHCO3) supplementation in diets for growing lambs on meat fatty acids composition. A slaughter study was carried out on 12 male Black Belly Barbados lambs randomly drawn from a prior growth trial (245 days). The lambs were divided into four equal groups and allotted in a 2×2 factorial design. ...

Escherichia coli C20, isolated from domestic chicken gut microbiota, demonstrated multidrug resistance to the tested antibiotics. Here, we present the draft genomic sequences of E. coli C20, along with that of its plasmid. The final assembly yielded a chromosome of 4,640,940 bp and plasmid of 277,380 bp, with average coverages of 146.95-fold and 35.63-fold, respectively.

To improve beef quality, a selection of specific breeds for crossbreeding, genotyping, and candidate genes in breeding animals can be some the solutions. The objective this study was to determine effects FASN, SCD, GH on carcass fatness fatty acid (FA) composition intramuscular lipids crossbred Holstein × (Simmental, Belgian Blue, Limousin, Piemontese). allelic genotypic distribution polymorphi...

The diether core membrane lipid sesterterpanyl-phytanyl-glycerol (so-called extended archaeol and often abbreviated C20-C25) is considered as a hallmark of Haloarchaea, clade archaea thriving under extreme high salinities. We here report about occurrence in different saline aquatic settings with salinity ranging from ca. 50 psu (5 % NaCl w/v) to saturation (ca. 350 psu). This demonstrates that ...
