BACKGROUND There is increasing evidence that cell elastic properties should change considerably in response to chemical agents affecting the physiological state of the endothelium. In this work, a novel assay for testing prospective endothelium-targeted agents in vitro is presented. MATERIALS AND METHODS The proposed methodology is based on nanoindentation spectroscopy using an atomic force m...

Three hundred cases of invasive breast cancer diagnosed between 1983 and 1999 in Calabar, Nigeria were analysed to determine the nuclear morphometric variables, and evaluate the prognostic potential of nuclear morphometry in Nigerian breast cancers. The necessary follow-up was available for 129 patients. The nuclear area was the most valuable variable. In the Nigerian material, the mean nuclear...

The present study was aimed to validate two normalised short-form (SF) Mini-Nutritional Assessments (MNA) that contained either BMI (Taiwan version 1, T1) or calf circumference (CC; Taiwan version 2, T2) for rating the nutritional status of elderly Taiwanese. Both versions adopted Taiwanese anthropometric cut-offs, but T2 further had the BMI item replaced by CC. We compared the ability of the t...

The cytochrome P450 (CYP) isoforms that catalyze the oxidation metabolism of 6-methoxy-2-napthylacetic acid (6-MNA), an active metabolite of nabumetone, were studied in rats and humans. Using an extractive reversed-phase HPLC assay with fluorescence detection, monophasic Michaelis-Menten kinetics was obtained for the formation of 6-hydroxy-2-naphthylacetic acid (6-HNA) in liver microsomes of ra...

OBJECTIVES Weight loss and malnutrition are frequent and serious complications of Alzheimer's disease. The aim of the present article was to describe the cognitive and behavioural characteristics of the test population within the frame of the PHRC REAL.FR cohort (for Réseau sur la Maladie d'Alzheimer Français), depending on their nutritional state, and to consider their evolution one year after...

BACKGROUND Nutritional screening instruments need to be evaluated in terms of reliability and validity and being able to demonstrate sensitivity and specificity for use in clinical practice and research. The aims of this study were to test the reliability and validity of the Norwegian version of the Nutritional Form For the Elderly (NUFFE-NO) in a sample of older home-dwelling people, and to us...

It has already been reported that 1-methylnicotinamide (MNA+), a primary metabolite of nicotinamide (vitamin B3), possesses remarkable anti-inflammatory properties [3]. This communication shows that 1-methyl-N'-(hydroxymethyl)nicotinamide (MNAF+ can be regarded as MNA+ precursor able to release simultaneously formaldehyde. Therefore, MNAF+ can be viewed as a candidate for drug with the combined...

BACKGROUND MYCN amplification (MNA) in neuroblastoma is a strong indicator of poor prognosis. However, some MYCN nonamplified (non-MNA) cases show poor outcomes, and examining the status of the gene requires an operation, which may have surgical complications. Therefore, a new marker is needed to identify cases of non-MNA neuroblastomas with poor prognoses using less risky procedures. Aberrant ...

This cross sectional study was conducted to determine the validity of three screening tools, Mini Nutritional Assessment Short Form (MNA-SF), Malnutrition Risk Screening Tool for Community (MRST-C) and Malnutrition Risk Screening Tool for Hospital (MRST-H) among elderly people at health clinics. The screening tools were validated against anthropometric and functional assessments. The anthropome...
