Impact of metformin versus the prandial insulin secretagogue, repaglinide, on fasting and postprandial glucose and lipid responses in non-obese patients with type 2 diabetes

Objective: Non-obese patients with type 2 diabetes (T2DM) are characterized by predominant defective insulin secretion. However, in non-obese T2DM patients, metformin, targeting insulin resistance. is non-inferior to the prandial insulin secretagogue, repaglinide, controlling overall glycaemia (HbA(1c)). Whether the same apply for postprandial glucose and lipid metabolism is unknown. Here. we comp

Large variations in the propensity of aqueous oxychlorine anions for the solution/vapor interface

Core-level photoelectron spectroscopy measurements have been performed of aqueous solutions of NaCl codissolved with NaClOn (n=1-4). Each species has a distinct Cl 2p electron binding energy, which can be exploited for depth-profiling experiments to study the competition between Cl-and ClOn- anions for residing in the outermost layers of the solution/vapor interface. Strongest propensity for the s

Microvessel density compared with the Chalkley count in a prognostic study of angiogenesis in breast cancer patients

Aims: Evaluation of angiogenesis by intratumoral vessel profiles can be performed by different methods. The aim of this study was to investigate the prognostic value of estimates obtained by the intratumoral microvessel density (MVD) method and then to compare with corresponding estimates obtained by the Chalkley method. Methods and Results: A total of 330 patients treated for primary, unilateral,

Effects of liming on ectomycorrhizal fungi infecting Pinus sylvestris L .1. Mycorrhizal infection in limed humus in the laboratory and isolation of fungi from mycorrhizal roots

Pinus sylvestris L. seedlings were grown in the laboratory in a forest humus which had been treated with different levels of CaO to give a soil pH gradient from 4 to 7. After 12 and 15 wk the resulting ectomycorrhizal infection was classified according to macroscopical morphology. The uniformity of the infection types distinguished was evaluated by isolating the fungi from the root tips and infect

Relationship between respiratory symptoms and medical treatment in exacerbations of COPD

Exacerbations of chronic obstructive pulmonary disease (COPD) can be defined symptomatically or by healthcare contacts, yet the relationship between these events is unknown. Data were collected during a 1-yr study of the budesonide/formoterol combination in COPD patients, where exacerbations, defined by increases in treatment, were compared with daily records of respiratory symptoms, rescue medica

Prevalence of self reported hip symptoms, relations to age, gender, pain, stiffness, weakness and other joint disorders

The objective was to estimate the prevalence and characteristics of self-reported hip disorders in an adult population-based sample from the general population in two defined primary healthcare districts in the south of Sweden. We used a population-based survey using a mailed questionnaire on a random sample of 2600 individuals aged 38-77 years. After two written reminders, the response rate was 8

The predictive value of bcl-2, bax, bcl-xL, bag-1, fas, and fasL for chemotherapy response in advanced breast cancer

Purpose: The purpose was to evaluate the utility of some bcl-2 family proteins fas and fasL as predictive indicators for chemotherapy response in advanced breast cancer. Experimental Design: Between October 1994 and October 1997, 283 patients with advanced breast cancer were included in a multicenter randomized study comparing docetaxel (D) to sequential methotrexate and 5-fluorouracil (MF) after

Gels of hydrophobically modified ethyl (hydroxyethyl) cellulose cross-linked by amylose: Effects of hydrophobe architecture

Previous work has shown that amylose (AM) can cross-link hydrophobically modified polymers by inclusion complexation, whereby thermoreversible cold-setting gels are formed. Here we investigate the complexation of AM with different samples of hydrophobically modified ethyl(hydroxyethyl) cellulose (HMEHEC), distinguished by differences in the architecture of the hydrophobes (the hydrophobic side cha

Plant species and functional group effects on abiotic and microbial soil properties and plant-soil feedback responses in two grasslands

1 Plant species differ in their capacity to influence soil organic matter, soil nutrient availability and the composition of soil microbial communities. Their influences on soil properties result in net positive or negative feedback effects, which influence plant performance and plant community composition. 2 For two grassland systems, one on a sandy soil in the Netherlands and one on a chalk soi

Radiative lifetime and transition probabilities in CdI and CdII

Radiative lifetimes of 11 levels belonging to the 5s5p P-1(1)o 5snd D-3(1,2) (n=6-9) and 5sns S-3(1) (n=7,8) series of Cd I, and of 5 levels of Cd II (i.e., 4d(10)5p P-2(1/2.3/2)o, 4d(10)6s S-2(1/2), and 4d(10)5d D-2(3/2,5/2)) have been measured using the time-resolved laser-induced fluorescence technique. Free neutral and singly ionized cadmium atoms have been generated by laser ablation. Single-

Reproductive behaviour of female Siberian lemmings during the increase and peak phase of the lemming cycle

The reproduction of female Siberian lemmings in the increase and peak phases of the lemming cycle was investigated in connection with a ship-borne expedition along the Siberian arctic tundra. The cycle phase of each studied lemming population was determined using demographic analyses, i.e. current density indices (captured lemmings per 100 traps per 24 h), information on previous density (frequenc

Hypoxia alters gene expression in human neuroblastoma cells toward an immature and neural crest-like phenotype.

Insufficient oxygen and nutrient supply often restrain solid tumor growth, and the hypoxia-inducible factors (HIF) 1 alpha and HIF-2 alpha are key transcription regulators of phenotypic adaptation to low oxygen levels. Moreover, mouse gene disruption studies have implicated HIF-2 alpha in embryonic regulation of tyrosine hydroxylase, a hallmark gene of the sympathetic nervous system. Neuroblastoma

Lipopolysaccharide induces cell death in cultured porcine myenteric neurons.

Enteric bacteria execute, via lipopolysaccharide (LPS), a pathogenic role in intestinal inflammation. The effects of LPS on survival and neurotransmitter expression in cultured porcine myenteric neurons were investigated. Myenteric neurons were isolated and cultured for 6 days in medium, in LPS (100 ng/ml) with or without α-ketoglutarate or the nitric oxide synthase (NOS) inhibitor L-NAME, in α-ke

Effect of button location on driver's visual behaviour and safety perception

Although buttons are a frequently used type of control in car interiors, little research has been undertaken on how the usage of buttons affects the visual behaviour of the driver. In this study, the aim was to analyse the effect of push button location and auditory feedback on drivers' visual time off road and safety perception when driving in a real traffic situation. The effect of six button lo

Investigation of the algT operon sequence in mucoid and non-mucoid Pseudomonas aeruginosa isolates from 115 Scandinavian patients with cystic fibrosis and in 88 in vitro non-mucoid revertants

Pseudomonas aeruginosa is the dominant pathogen causing chronic lung infections in patients with cystic fibrosis (CF). After an initial phase characterized by intermittent colonizations, a chronic infection is established upon conversion of P. aeruginosa from the non-mucoid to the mucoid, alginate-overproducing phenotype. During the chronic infection the isolation of both mucoid and non-mucoid iso

Softwood hemicellulose-degrading enzymes from Aspergillus niger: Purification and properties of a β-mannanase

The enzymes needed for galactomannan hydrolysis, i.e. β-mannanase, α-galactosidase and β-mannosidase, were produced by the filamentous fungus Aspergillus niger. The β-mannanase was purified to electrophoretic homogeneity in three steps using ammonium sulfate precipitation, anion-exchange chromatography and gel filtration. The purified enzyme had an isoelectric point of 3.7 and a molecular mass of

Correlation between an early sexual debut, and reproductive health and behavioral factors: a multinational European study

OBJECTIVE: To investigate whether women who made an early sexual debut differ from those with a later debut regarding genital signs and symptoms. METHODS: The study included women who considered themselves gynecologically healthy and who attended 17 family planning centers in 13 European countries for contraceptive advice. There were 629 women who made their sexual debut at the age of 16 years or
