Although subjective global assessment (SGA) is a widely used tool for nutritional investigation, the scores are dependent on the inspectors' subjective opinions, and there are only few studies that directly assessed the usefulness of SGA and modified SGA in incident peritoneal dialysis (PD) patients. A total of 365 incident PD patients between 2009 and 2015 were enrolled and measured with SGA a...

BACKGROUND Previous CSF studies in Rett syndrome suggest reduced turnover of the biogenic monoamines serotonin and dopamine. Because diminished turnover may result from CNS folate depletion, the authors studied transport of folate across the blood-brain barrier. METHODS In four patients with Rett syndrome, the authors measured CSF values of 5-methyltetrahydrofolate (5MTHF), biogenic monoamine...

The toxicity of alfatoxin B(2a) (hydroxydihydro-aflatoxin B(1)) was studied in several biological systems. Aflatoxin B(2a) is the monohydroxylated derivative obtained from addition of water to the double bond of the terminal furan of B(1). Examination of the sensitivity of a group of microorganisms to B(2a) demonstrated that the inhibitory spectrum was similar to aflatoxin B(1). However, the to...

Barley hordein was comparable to maize zein in antioxidation under a powder model system. Various deamidated "hordein" preparations were obtained and examined for their molecular-size distribution (by Sephacryl S-100 gel filtration), hydrophobicity (by fluorescence measurement using fluorescent probes) and antioxidative activity (by the ferric thiocyanate method). Deamidation caused fragmentati...

The binding behavior of a competitive inhibitor, N-phenylbenzhydroxamic acid (BHA) against horseradish peroxidase (HRP) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the enzyme. The dissociation constants of the complexes of HRP-BHA, HRP-donor and HRP-BHA-azide were estimated at specified conditions by difference spectroscopy. The binding s...

the binding of sodium n-dodecyl sulphate (sds) to aspergillus niger catalase in various ionic strengths at ph 6.4 and a temperature of 27? and 37?c has been studied over a range of sds concentrations using equilibrium dialysis and fluorescence spectroscopy techniques. the binding data were used and interpreted in terms of theoretical models (scatchard equation and wyman binding potential). the ...
