Neurocognitive functions in patients with hepatitis C infection.

Background And Purpose: With improving treatment options, more attention is being paid to the neurocognitive symptoms related to hepatitis C infection (HCI). While HCI-related neurocognitive impairments are frequently subclinical, they can influence patients' quality of life and fitness to work. Objective - The aim of this study was to assess HCI patients' neurocognitive functions and explore the correlations between disease variables and neurocognitive symptoms.

Effect of hepatitis C infection on the quality of life.

Purpose: To assess the quality of life (QoL) of patients with hepatitis C infection (HCI) and its correlations with demographic and clinical variables.

Design And Methods: QoL and depressive symptoms were evaluated with the validated rating instruments of the 36-item short form (SF-36) generic health survey and the second version of the self-rated Beck depression inventory (BDI-II) in a cross-sectional design and correlated with basic demographic and clinical variables, including the Fibroscan score, which indicates the severity of liver impairment.

Findings: A cohort of 60 HCI patients who participated in the study scored lower than the general population on all domains of the SF-36.

Substrate binding properties of L-glycerol-3-phosphate dehydrogenase in isolated liver mitochondria of hyperthyroid rats.

In isolated, intact liver mitochondria from hyperthyroid rats, the L-glycerol-3-phosphate binding site(s) of the L-glycerol-3-phosphate dehydrogenase was (were) found to be influenced by the nature of the electron acceptor, as well as by the pH and the presence of calcium ions. With the hydrophobic electron acceptor menadione a single L-glycerol-3-phosphate binding site was detected kinetically at bulk pH values between 6.5 and 9.

Double inhibition of L-threonine dehydratase by aminothiols.

The inhibition of highly purified rat liver L-threonine dehydratase (L-threonine hydro-lyase (deaminating), EC 4.2.1.

Transient-time analysis of substrate-channelling in interacting enzyme systems.

The kinetics of dynamically interacting enzyme systems is examined, in the light of increasing evidence attesting to the widespread occurrence of this mode of organization in vivo. The transient time, a key phenomenological parameter for the coupled reaction, is expressed as a function of the lifetime of the intermediate substrate. The relationships between the transient time and the pseudo-first-order rate constants for the coupled reaction by the complexed and uncomplexed enzyme species are indicative of the mechanism of intermediate transfer ('channelling').
