Nateglinide Improves Early Insulin Secretion and Controls Postprandial Glucose Excursions in a Prediabetic Population.

OBJECTIVE—The purpose of this study was to evaluate the metabolic effectiveness, safety, and tolerability of nateglinide in subjects with impaired glucose tolerance (IGT) and to identify a dose appropriate for use in a diabetes prevention study. RESEARCH DESIGN AND METHODS—This multicenter, double-blind, randomized, parallel-group, fixed-dose study of 8 weeks’ duration was performed in a total of

Quantification of ovarian power Doppler signal with three-dimensional ultrasonography to predict response during in vitro fertilization

OBJECTIVE: To evaluate whether power Doppler predicts ovarian response to gonadotrophin stimulation during in vitro fertilization (IVF). METHODS: Forty-five women were divided into low-reserve (n = 12) and normal-reserve (n = 33) ovarian groups, according to antral follicle count. Transvaginal three-dimensional power Doppler ultrasonographic examinations were performed after pituitary downregulati

Diffusion rates in a dense matrix of methane-producing microorganisms

The diffusion rate of a species, in a dense matrix of methane-producing microorganisms, was determined experimentally. To this end, a specially designed diaphragm diffusion cell was utilized. The experimental results revealed that the effective diffusion coefficient in a microorganism matrix was 22–33% of the diffusion coefficient in pure water.

Multiple risk intervention trial in high risk hypertensive men: comparison of ultrasound intima-media thickness and clinical outcome during 6 years of follow-up

OBJECTIVES: The objective was to analyse whether a favourable change in risk factors, caused by a comprehensive risk factor modification programme, affected intima-media thickness (IMT) in the common carotid artery, and whether any such change was associated with a change in cardiovascular events during a 6-year follow-up. DESIGN: Patients were randomized 1 : 1 to special intervention or usual car

Decreased metastatic spread in mice homozygous for a null allele of the cystatin C protease inhibitor gene

AIMS: Increased or altered activities of cysteine proteases have been implicated in serious human disorders such as cancer, rheumatoid arthritis, sepsis, and osteoporosis. To improve the current knowledge of the regulatory role of a major mammalian cysteine protease inhibitor, cystatin C, in such disease processes, a cystatin C deficient mouse was generated and characterized. METHODS: The mouse cy

IL-2 overcomes the unresponsiveness but fails to reverse the regulatory function of antigen-induced T regulatory cells

Intranasal administration of peptide Acl-9[4Y], based on the N-terminal epitope of myelin basic protein, can induce CD4(+) T cell tolerance, and suppress experimental autoimmune encephalomyelitis induction. The peptide-induced regulatory T (PI-T-Reg) cells failed to produce IL-2, but expressed IL-10 in response to Ag and could suppress naive T cell responses in vitro. Analysis of Jak-STAT signalin

Revision of the CEAP classification for chronic venous disorders: Consensus statement

The CEAP classification for chronic venous disorders (CVD) was developed in 1994 by an international ad hoc committee of the American Venous Forum, endorsed by the Society for Vascular Surgery, and incorporated into "Reporting Standards in Venous Disease" in 1995. Today most published clinical papers on CVD use all or portions of CEAP. Rather than have it stand as a static classification system, a

Development of educational image databases and e-books for medical physics training

Medical physics education and training requires the use of extensive imaging material and specific explanations. These requirements provide an excellent background for application of e-Learning. The EU projects Consortia EMERALD and EMIT developed five volumes of such materials, now used in 65 countries. EMERALD developed e-Learning materials in three areas of medical physics (X-ray diagnostic rad

A numerical investigation of gas flow and heat transfer in proton exchange membrane fuel cells

Gas flow and heat transfer in both cathode and anode channels have been modeled and analyzed for proton exchange membrane fuel cells. The simulated channel consists of a porous electrode layer (anode or cathode), gas flow duct, and solid current collector. The characteristics of gas flow and heat transfer in terms of friction factor and Nusselt number were investigated by a three-dimensional compu

Comparison of Endorette and dilatation and curettage for sampling of the endometrium in women with postmenopausal bleeding

MAIN QUESTION: To compare the diagnostic properties of Endorette and D&C in women with postmenopausal bleeding, to relate the properties to endometrial thickness as measured by ultrasound, and to assess the women's experiences of the two methods. METHODS: In a prospective study, 133 consecutive women with postmenopausal bleeding were examined with transvaginal ultrasound. After measuring the e

Kinematic and kinetic gait analysis in the sagittal plane of trans-femoral amputees before and after special gait re-education.

A special gait-training programme, combining a psychological therapeutic approach with methods in physiotherapy and body awareness, was used to re-educate nine unilateral trans-femoral amputees. All were rehabilitated trauma or tumour amputees with an age of 16-60 years. They had worn prostheses for more than 18 months. The re-education aimed at integrating the prosthesis in normal movements and i

Continuity of the percolation threshold in randomly grown graphs

We consider various models of randomly grown graphs. In these models the vertices and the edges accumulate within time according to certain rules. We study a phase transition in these models along a parameter which refers to the mean life-time of an edge. Although deleting old edges in the uniformly grown graph changes abruptly the properties of the model, we show that some of the macro-characteri

Electrospray ionization mass spectrometry in enzymology: uncovering the mechanisms of two- substrate reactions

The purpose of this review is to draw attention to the use of electrospray ionization mass spectrometry ( ESI-MS) for monitoring the course of enzyme substrate interactions, in the particular case of complex systems in which two substrates participate. The determination and characterization of intra-molecular reactions, especially those that occur in the enzyme active site, is not a trivial task i
