Pulsed field gradient NMR study of poly(ethylene glycol) diffusion in whey protein solutions and gels

PEG self-diffusion coefficients of poly(ethylene glycol)s (PEGs) (1080, 8500, and 82 250 g/mol) were measured by PFG-NMR spectroscopy in whey protein solutions and gels in relation to whey protein concentration effects (from 6.49 to 40.45 g/100 g) and whey protein heat denaturation effects (30 min at 70 degrees C). A strong dependency of diffusion on probe size was observed in both whey protein so

The happy obese child

OBJECTIVE: Firstly, is the negative psychological effect of obesity also present in the whole population of obese and overweight children? Secondly, what tools could be recommended to measure the psychological effects of obesity? DESIGN: Review. METHODS: Quality of life or self-esteem is often used in evaluating the psychological effects of obesity. Test instruments used have been instruments for

Influence of treatment with diethylstilbestrol for carcinoma of prostate on platelet aggregation and plasma lipoproteins

Treatment of prostatic carcinoma with estrogens is accompanied by an increased risk for thromboembolic and cardiovascular complications. The underlying mechanisms are still unknown. Patients treated with diethylstilbestrol (DES) were compared with patients given no estrogen treatment regarding factors (platelet aggregation in vitro and plasma lipoproteins) that have been suggested to contribute to

Transient post-mating inhibition of behavioural and central nervous responses to sex pheromone in an insect

Mating is costly for both male and female insects and should therefore only occur if it is likely to be successful. Within one scotophase, which is the dark period of the light cycle, male moths can only produce one single spermatophore, which is transferred to the female during mating. Remating within the same scotophase would thus be unsuccessful. We tested the hypothesis that newly mated males

Hyperfine-interaction-dependent 4s4p P-3(2) lifetimes in Zn-like ions

Theoretical studies on hyperfine-interaction-dependent lifetimes of the 4s4p P-3(2) states of Zn-like ions are reported in this paper. A systematic investigation along the isoelectronic sequence shows that the lifetime of the 4s4p P-3(2) level is very sensitive to hyperfine interaction at the beginning of the sequence, but gets less sensitive going to the higher end. The intensity ratio between th

Return of collective rotation in Er-157 and Er-158 at ultrahigh spin

A new frontier of discrete-line gamma-ray spectroscopy at ultrahigh spin has been opened in the rare-earth nuclei Er-157,Er-158. Four rotational structures, displaying high moments of inertia, have been identified, which extend up to spin similar to 65h and bypass the band-terminating states in these nuclei which occur at similar to 45h. Cranked Nilsson-Strutinsky calculations suggest that these s

Protein D, the glycerophosphodiester phosphodiesterase from Haemophilus influenzae with affinity for human immunoglobulin D, influences virulence in a rat otitis model

A mutant lacking the ability to express the surface-exposed lipoprotein protein D was constructed by linker insertion and deletion mutagenesis of a cloned DNA insert containing the protein D structural gene from a nontypeable Haemophilus influenzae strain (NTHi). An isogenic NTHi mutant was isolated after transformation of genetically competent bacteria. The transformant was unreactive to a protei

Nonadiabatic effects in photoelectron spectra of HCl and DCl. I. Experiment

The HCl inner-valence photoelectron band at 26 eV binding energy has been recorded at high resolution. Discrete peaks arising from at least two separate vibrational progressions are superimposed on the broad continuum. Fano profiles are visible in one of the progressions. This indicates interference between superimposed electronic states, where weak avoided crossing allows two adiabatic states to

Maximum daily energy intake: It takes time to lift the metabolic ceiling

Conventionally, maximum capacities for energy assimilation are presented as daily averages. However, maximum daily energy intake is determined by the maximum metabolizable energy intake rate and the time available for assimilation of food energy Thrush nightingales (Luscinia luscinia) in migratory disposition were given limited food rations for 3 d to reduce their energy stores. Subsequently, grou

Bootstrap methods for autocorrelation test with uncorrelated but not independent errors

By using bootstrap technique we investigate the properties of the Breusch [Breusch, T.S., 1978. Testing for autocorrelation in dynamic linear models. Australian Economic Papers 17, 334-355]-Godfrey [Godfrey, L.G., 1978. Testing for higher order serial correlation in regression equations when the regressors include lagged dependent variables.

Root competition influences pollen competitive ability in Viola tricolor: effects of presence of a competitor beyond resource availability?

1. It has recently been suggested that not only nutrients but also presence of a competitor can influence competitive ability in plants, for example, by strategic changes in allocation to roots (a 'tragedy of the commons' effect). Such strategic changes might occur also in pollen, because this has potential to increase siring success during pollen competition in the pistil. 2. I tested the new hyp

Gabapentin in traumatic nerve injury pain: A randomized, double-blind, placebo-controlled, cross-over, mufti-center study

A double-blind, randomized, placebo-controlled cross-over multi-center study was conducted to evaluate the efficacy and safety of gabapentin in the treatment of neuropathic pain caused by traumatic or postsurgical peripheral nerve injury, using doses tip to 2400 mg/day. The study comprised a run-in period of two weeks, two treatment periods of five weeks separated by a three weeks' washout period.

Effect of titanium substitution in approximate to SbVO4 used for propane ammoxidation

Catalysts of the nominal composition Sb0.9V0.9-xTixOy, 0.0 less than or equal to x less than or equal to 0.9, were prepared and characterized with X-ray diffraction, Fourier transform-Raman spectra, diffuse reflectance infrared Fourier transform spectra, transmission electron microscopy, electron diffraction, and X-ray microanalysis. The catalysts were used for the ammoxidation of propane to give

Intracapsular pressure and elasticity of the hip joint capsule in osteoarthritis

We investigated intracapsular pressure and elasticity of the hip joint capsule in osteoarthritis. HOOS hip score, sonography of the hip joint, and radiographic assessment of osteoarthritis were performed in 31 patients before total hip arthroplasty. The intracapsular hydrostatic pressure was measured perioperatively, and 0.9% saline solution was then injected in the hip joint, 1 mL at a time with

Estimating environmental effects on population dynamics: consequences of observation error

Within the paradigm of population dynamics a central task is to identify environmental factors affecting population change and to estimate the strength of these effects. We here investigate the impact of observation errors in measurements of population densities on estimates of environmental effects. Adding observation errors may change the autocorrelation of a population time series with potentia

On holomorphic harmonic morphisms

We study holomorphic harmonic morphisms from Kahler manifolds to almost Hermitian manifolds. When the codomain is also Kahler we get restrictions on such maps in the case of constant holomorphic curvature. We also prove a Bochner-type formula for holomorphic harmonic morphisms which, under certain curvature conditions of the domain, gives insight to the structure of the vertical distribution. We t

Are emotions important for good interaction in treatment situations?

Emotional aspects in interaction have been an area of growing interest in recent decades.The aims of this research were to investigate the role of emotions in interactions between individuals receiving physiotherapy and their therapists providing PT services to them in psychiatric care. The study was a qualitative case study with cross-case analysis according to Shephard et al (1993) and Merriam (
