Amperometric response from the glycolytic versus the pentose phosphate pathway in Saccharomyces cerevisiae cells

The two main metabolic pathways involved in sugar metabolism, i.e., the pentose phosphate pathway (PPP) and the glycolytic pathway (GP), were amperometrically monitored using a double-mediator system composed of menadione and ferricyanide. With the use of the Saccharomyces cerevisiae deletion mutant, EBY44, lacking the gene encoding for the branch point enzyme phosphoglucose isomerize, selective a

An Examination of the Possibility of Lowering the Glycemic Index of Oat and Barley Flakes by Minimal Processing

Differences in glycemic responses to various starchy foods are related to differences in the rate of starch digestion and absorption. In this study, the importance of the degree of gelatinization and the product thickness for postprandial glycemic and insulinemic responses to rolled oats and barley were studied in healthy subjects (5 men and 5 women). Thick (1.0 mm) rolled oats were made from raw

Insertion of Self-Expandable Nitinol Stents Without Previous Balloon Angioplasty Reduces Restenosis Compared with PTA Prior to Stenting.

Purpose: To compare the development of intimal hyperplasia after deployment of a self-expanding nitinol stent with and without previous percutaneous transluminal balloon angioplasty (PTA), with the results after PTA alone. Methods: In nine healthy pigs, the iliac arteries were divided into three groups: group 1 (n = 6 arteries) was treated with PTA; group 2 n = 6) with insertion of self-expanding

Tumor attenuation by combined heparan sulfate and polyamine depletion.

Cells depend on polyamines for growth and their depletion represents a strategy for the treatment of cancer. Polyamines assemble de novo through a pathway sensitive to the inhibitor, alpha-difluoromethylornithine (DFMO). However, the presence of cell-surface heparan sulfate proteoglycans may provide a salvage pathway for uptake of circulating polyamines, thereby sparing cells from the cytostatic e

The kinetics of leucocyte migration into rabbit knee joints elicited by preformed immune complexes with different in vitro characteristics

Immune complexes were formed in vitro with antibodies obtained from rabbits immunized with bovine serum albumin in Freund's complete (FCA) or incomplete (FIA) adjuvant. The antibodies were mixed with different amounts of antigen. Immune complexes formed at maximum precipitation proportions were efficient in complement activation, whereas immune complexes formed at antigen excess had weak complemen

Role of fimbriae-mediated adherence for neutrophil migration across Escherichia coli-infected epithelial cell layers

This study examined the role of P and type 1 fimbriae for neutrophil migration across Escherichia coli-infected uroepithelial cell layers in vitro and for neutrophil recruitment to the urinary tract in vivo. Recombinant E. coli K-12 strains differing in P or type 1 fimbrial expression were used to infect confluent epithelial layers on the underside of transwell inserts. Neutrophils were added to t

Use of PLL-g-PEG in micro-fluidic devices for localizing selective and specific protein binding

By utilizing flow-controlled PLL-g-PEG and PLL-g-PEGbiotin modification of predefined regions of a poly-(dimethylsiloxane) (PDMS) micro-fluidic device, with an intentionally chosen large (similar to 1 cm(2)) internal surface area, we report rapid (10 min), highly localized (6 x 10(-6) cm(2)), and specific surface-based protein capture from a sample volume (100 mu L) containing a low amount of prot

IDENTIFICATION OF BTK MUTATIONS IN 20 UNRELATED PATIENTS WITH X-LINKED AGAMMAGLOBULINEMIA (XLA)

X-linked agammaglobulinaemia (XLA) is an inherited immunodeficiency resulting from mutations in the gene for a cytoplasmic protein tyrosine kinase (Btk), We have utilised reverse-transcription-based PCR in combination with the chemical cleavage and mismatch technique (CCM) to screen for Btk mutations in 42 unrelated patients having classical XLA or 'leaky' XLA-like phenotypes. A variety of mutatio

No evidence for activation of the unfolded protein response in neuronopathic models of Gaucher disease

Gaucher disease (GD), the most common lysosomal storage disorder (LSD), is caused by defects in the activity of the lysosomal enzyme, glucocerebrosidase, resulting in intracellular accumulation of glucosylceramide (GlcCer). Neuronopathic forms, which comprise only a small percent of GD patients, are characterized by neurological impairment and neuronal cell death. Little is known about the pathway

Quality of life among older people in Sweden receiving help from informal and/or formal helpers at home or in special accommodation

The present study describes and compares quality of life (QoL) and factors which predict QoL among people aged 75 years and over who receive help with activities of daily living (ADLs) from formal and/or informal helpers. The subjects were living at home or in special accommodation in Sweden. A postal questionnaire was sent to a randomly selected and age-stratified sample of 8500 people. The respo

Effect of temperature decrease on the microbial population and process performance of a mesophilic anaerobic bioreactor

The effect of a temperature decrease from 33 degrees C to 12 degrees C was investigated for anaerobic digestion of crop residues. A laboratory-scale reactor (R,) was inoculated with mesophilic sludge and operated as continuously stirred fed-batch system at temperatures of 12 degrees C, 18 degrees C and 33 degrees C. Changes in the microbial populations of the sludge were followed by means of fluor
