1. The simultaneous effects of an intravenous glucose infusion on plasma urea, glucose and alanine kinetics were investigated in normal post-absorptive man. 2. The primed constant intravenous infusion of compounds labelled with stable isotopes, [15N2]urea, [6-2H]glucose and [3-13C]alanine, was used. 3. The rate of appearance of glucose and urea in the plasma was rapidly reduced by the 17.7 mumo...

In the title compound, C(17)H(13)ClN(4)OS, the 1,3,4-thia-diazole ring makes dihedral angles of 9.70 (15) and 7.22 (10)° with the benzene and phenyl rings, respectively; the dihedral angle between these two rings is 6.37 (19)°. In the crystal, pairs of N-H⋯N and C-H⋯O hydrogen bonds between inversion-related mol-ecules result in supra-molecular ribbons displaying alternate R(2) (2)(8) and R(2) ...

BACKGROUND The current, arbitrarily defined gold standard for the diagnosis of H. pylori infection requires histologic examination of two specially stained antral biopsy specimens. However, routine histology is potentially limited in general clinical practice by both sampling and observer error. The current study was designed to examine the diagnostic performance of invasive and non-invasive H....

Spring dead spot (SDS), caused by Ophiosphaerella spp., is among the most damaging diseases to hybrid bermudagrass ( Cynodon dactylon × transvaalensis ) in areas where winter dormancy occurs. Management strategies that aid turfgrass recovery from SDS damage have not been widely studied. An experiment was conducted Blacksburg, VA, 2019 and 2020, determine influence of various cultural practices ...

This study examines the role of glucagon and insulin in the incorporation of (15)N derived from (15)N-labeled glutamine into aspartate, citrulline and, thereby, [(15)N]urea isotopomers. Rat livers were perfused, in the nonrecirculating mode, with 0.3 mM NH(4)Cl and either 2-(15)N- or 5-(15)N-labeled glutamine (1 mM). The isotopic enrichment of the two nitrogenous precursor pools (ammonia and as...

The present study was undertaken to estimate the serum urea, creatinine and electrolyte status of patients presenting with acute gastroenteritis. Sixty patients who presented to Kathmandu Medical College and Teaching hospital from 15 June to 15 July 2005 with acute diarrhea with or without associated vomiting, causing dehydration severe enough to require hospital admission were investigated for...
