There are some classical markers of uremic solute retention, such as serum urea and creatinine concentration. These parameters are however not always reliable, especially not in dialysis patients, so that it seemed interesting to us to undertake a multifactorial study, in an attempt to define the most suitable marker molecules in uremia.

Identification of hippurate-negative thermophilic campylobacters
Diagnostic Microbiology and Infectious Disease, 1999Twenty-eight thermophilic campylobacter isolates showing negative hippurate hydrolysis were further characterized. Using Campylobacter jejuni and coli specific primers for ceuE gene, five of the isolates with repeatedly negative results in rapid hippurate hydrolysis were positive in C.

Methenamine Hippurate (Hiprex)
2019Since as early as the 1970s, Methenamine hippurate (Hiprex) has been used in the prevention of recurrent urinary tract infections [1]. Hiprex works via two pathways [2].

Hippuric Acid Excretion, Coffee, and Schizophrenia
Archives of General Psychiatry, 1963Urinary excretion of hippuric acid in man has at times been associated with the emotional state. Thus, institutionalized schizophrenic patients are reported to excrete abnormally low amounts of this acid, after administration of benzoic acid (Quastel and Wales, 1938; Strom-Olsen et al, 1938; and Wong, 1945), while anxiety states are believed to result ...

Trypsin hydrolysis of X-phenyl hippurates
Chemico-Biological Interactions, 1988The kinetics of hydrolysis of eight substituted phenyl hippurates by trypsin at pH values 6, 7 and 8 were investigated and the kinetic constants Km, kcat (kcatalysis) and kcat/Km were shown to fit the Hammett equation. The rho (rho) value obtained from the correlation of trypsin binding with this class of esters was compared with that obtained with ...

Quantitative hippurate renography.
Annales chirurgiae et gynaecologiae, 1985Effective renal plasma flow (ERPF) was determined by registration of 131I-hippurate radioactivity over the heart and calculation of the disappearance constants after fitting a three-exponential function to the measured time-activity curve. Right and left kidney ERPF was calculated both by a method of tangents and a new method of summed pulses from the ...

The stereochemistry of hippurate alkylation
Canadian Journal of Chemistry, 1998Alkylation of the hippurate esters of trans 2-(p-substituted phenyl)cyclohexanol with benzyl bromide affords phenylalanine derivatives in high chemical yield. The reaction stereoselectivity varies from 20 to >98% depending on the aromatic group in the cyclohexyl auxiliary. A model that correctly predicts the sense of the induction is proposed.

It has been reported that coffee intake results in an elevation of hippuric acid (HA) concentration in urine. Among the phenolic compounds in coffee, chlorogenic acid (CGA) is a major substance, metabolized to HA in the human body. In the metabolism of CGA, the colonic microflora play an important role, and there is large inter-individual variation ...

Titrimetric microdetermination of hippuric acid
Microchemical Journal, 1969Abstract Hippuric acid was determined quantitatively in micro amounts with indium sulfate, using catechol violet as indicator. Potentiometric results and present results confirm that a complex between indium and hippuric acid is formed in the ratio of 1:3. Maximum error in these experiments is 1.4%. Determinations up to 26.8770 × 10 −4 mg/liter were
