Keto-bromothymol blue [BTB]keto was quantitatively prepared by potassium permanganate oxidation of bromothymol in an alkaline medium at pH > 12. When reacting with dinitrophenyl hydrazine and hydroxylamine, the obtained keto derivatives were characterized FTIR, TDDFT-DFDT computations, optical properties. The resulting compounds found to have a high chelation affinity most hydroxylamine forming...

Acute renal failure is an uncommon complication among children with Diabetic keto acidosis. This has been recently reported from developing countries. Prerenal uremia which improves in few hours is common in DKA and this is fluid responsive, however intrinsic renal failure with increasing urea creatinine and anuria is associated with high mortality and is uncommon. Sepsis, shock, severe dehydra...

• Pillar array columns was applied to α-keto acids analysis. α-Keto were derivatized with 1,2-diamino-4,5-methylenedioxybenzene for fluorescence detection. Four separated on pillar in 160 s. Three branched-chain human plasma samples successfully quantified. Branched-chain (BCKAs, namely, α-ketoisovaleric acid (KIV), α-ketoisocaproic (KIC), and α-keto-β-methylvaleric (KMV)) are related many dise...

Palladium (II) coordination complexes catalyze the reaction of alcohols with ketones to yield ethers. During the catalytic cycle, the alcohol adds selectively to the β-carbon (anti-Markovnikov). In this work, mechanism and kinetics for the reaction of methanol with methyl vinyl ketone (MVK), being catalyzed by Pd, has been theoretically investigated in detail. Using quantum mechanical approach,...

objective(s)cardiovascular disease causes a major clinical problem in patients with end stage renal disease. since metabolic acidosis is very common in patients with end stage renal disease, we aimed to investigate the effect of experimentally-induced metabolic acidosis on serum lipid profile and aortic fatty streak (fs) formation in normal and high-cholesterol fed rabbits.materials and methods...

Using Hartree–Fock (HF) and ِِDensity Functional Theory (DFT) calculations the thermodynamic properties such as thermal energy , , thermal enthalpy , , thermal entropy , , thermal Gibbs free energy , , heat capacity ,Cv, and molecular structures of several species involving in keto↔enol tautomerism related to acetaldehyde (A), 5,5-dimethyl-1,3-cyclohexanedione (dimedone) and  acetylacetone (AA) h...

The regulation of the branched chain alpha-keto acid dehydrogenase multienzyme complex was investigated in the isolated, perfused rat liver. The metabolic flux through the branched chain alpha-keto acid dehydrogenase was monitored by measuring the production of 14CO2 from infused 1-14C-labeled branched chain alpha-keto acid substrates. The rate of decarboxylation of alpha-keto[1-14C]isocaproate...

background: metabolic acidosis is a fatal finding in trauma patients that complicates the process of resuscitation. case: the case was a 37-year-old man with open fracture in both legs and fracture in second lumbar vertebral (l2). the serial arterial blood gas (abg) test results showed a ph value of 6.7 indicating a very severe and special case of metabolic acidosis. the rate of mortality for s...
