OBJECTIVE We sought to validate questionnaires concerning body image perception, body size dissatisfaction and weight-related beliefs in multi-ethnic South African mothers and their daughters. SETTINGS AND SUBJECTS Girls attending primary school (ages 9-12 years, n = 333) and their mothers (n = 204) were interviewed regarding their demographics and body image. Weight, height and skinfold thic...

This paper describes two SlipChip-based approaches to protein crystallization: a SlipChip-based free interface diffusion (FID) method and a SlipChip-based composite method that simultaneously performs microbatch and FID crystallization methods in a single device. The FID SlipChip was designed to screen multiple reagents, each at multiple diffusion equilibration times, and was validated by scree...

the forced degradation study of lidocaine hcl was carried out according to the ich guideline q1a (r2). the degradation conditions were assessed to be hydrolysis, oxidation, photolysis and dry heat during 24 h, 48 h and 72 h and then the samples were investigated by gc-fid method and nuclear magnetic resonance (nmr) spectroscopy. according to these results, the degradation products were not obse...

RATIONALE Mitochondrial-derived hydrogen peroxide (H2O2) regulates flow-induced dilation (FID) in microvessels from patients with coronary artery disease. The relationship between ceramide, an independent risk factor for coronary artery disease and a known inducer of mitochondrial reactive oxygen species, and FID is unknown. OBJECTIVE We examined the hypothesis that exogenous ceramide induces...

BACKGROUND Urinary organic acids are water-soluble intermediates and end products of the metabolism of amino acids, carbohydrates, lipids, and a number of other metabolic processes. In the hereditary diseases known as organic acidurias, an enzyme or co-factor defect in a metabolic pathway leads to the accumulation and increased excretion of one or more of these acidic metabolites. Gas chromatog...

The Single Point Ramped Imaging with T1 Enhancement (SPRITE) sequence is well suited for the acquisition of magnetic resonance signals from fast relaxing nuclei and from heterogeneous materials. However, it is time inefficient compared to sequences that are based on frequency encoding because only one single point is acquired per excitation. Multiple-point SPRITE (mSPRITE) mitigates this proble...

We propose a new experimental protocol to investigate the atmospheric dispersion of dense gas in wind-tunnel experiments. Simultaneous measurements concentration and velocity are performed by coupling flame ionisation detector (FID) hot-wire anemometer (HWA), whose probes located sufficiently close each other so that respective correspond same sampling volume. The heavy emission consists mixtur...

a very simple, rapid and sensitive dispersive liquid-liquid microextraction (dllme) followed by gas chromatography and flame ionization detection (gc-fid) was developed for the determination of phenol and carvacrol in honey samples. a mixture of 100 µl dichloromethane (extraction solvent) and 0.5 ml acetonitrile (disperser solvent) was rapidly injected into sample solution. thereby a cloudy sol...

A dimeric neomycin-neomycin conjugate 3 with a flexible linker, 2,2'-(ethylenedioxy)bis(ethylamine), has been synthesized and characterized. Dimer 3 can selectively bind to AT-rich DNA duplexes with high affinity. Biophysical studies have been performed between 3 and different nucleic acids with varying base composition and conformation by using ITC (isothermal calorimetry), CD (circular dichro...
