Water-pipe (WP) smoking is on rise worldwide for the past few years, particularly among younger individuals. Growing evidence indicates that WP smoking is as harmful as cigarette smoking. To date, most of the research has focused on acute health effects of WP smoking, and evidence remains limited
BACKGROUND
In Curaçao, distilled seawater from the water plant was used without further purification for hemodialysis for several decades. A new distribution pipe supplying water to a dialysis center on the island was installed in May 1996. To protect it from corrosion, this pipe was lined on the
Chronic kidney disease is associated with the accumulation of a large range of uremic retention solutes as referred to as uremic toxins. Some of these compounds belong to the group of Protein Bound Uremic Toxins (PBUT) due to their tight interactions with plasma proteins and especially serum
OBJECTIVE
To examine the associations between cigarette smoking, pipe/cigar smoking, and years since quitting smoking, and inflammatory and haemostatic markers.
RESULTS
A study in 2920 men aged 60-79 with no history of myocardial infarction, angina, stroke, or diabetes, and who were not on warfarin,
Linear standard curves were obtained for 1 to 10 micrograms of bovine serum albumin measured in the presence of 50 mM Mes, Mops, Pipes, Caps, Bes, Hepes, Heppso, and Tes zwitterionic buffers using bicinchoninic acid for detection. The zwitterionic buffers Ada, Tricine, and Bicine that strongly bind
We describe the certification of a mass concentration value in the already prepared creatine kinase-2 reference material (BCR 608). Creatine kinase-2 was purified from human heart. The purified enzyme was diluted in order to measure its protein concentration by the Doetsch method. A protein
To make sure, whether the hygienic requirements and the ecotoxicologic ones are excluding each other or not, several studies in dishwashing machines under practical conditions have been done. The requirements from the hygienic point of view have been fixed at a 5 lg--reduction of E. faecium ATCC
Two workers are presented who were exposed to diphenylmethane diisocyanate (MDI) while coating pipes with a polyurethane foam. After a latent period of exposure, worker A developed immediate-onset asthma and worker B developed a clinical picture of hypersensitivity pneumonitis for which he was
OBJECTIVE
To evaluated the independent effects of different types of smoking exposure along with multiple risk factors for hepatocellular carcinoma (HCC) and determined whether the magnitude of smoking was modified by other risk factors, both in men and women.
METHODS
We conducted a case-control
We describe the preparation of a lyophilized material containing purified human pancreatic alpha-amylase and the certification of its catalytic concentration. The enzyme was purified from human pancreas by ammonium sulphate precipitation and chromatography successively on DEAE-Sephacel, CM-Sepharose
We have demonstrated a concentration-dependent dissociation of bovine brain tubulin dimer covalently labeled with 5-[(4,6-dichlorotriazin-2-yl)amino]fluorescein (DTAF) or with fluorescein isothiocyanate (FITC) by fluorescence anisotropy and size-exclusion HPLC. The fluorescence anisotropy values
We describe the preparation of a lyophilized material containing purified human creatine kinase 2 (CK-MB), and the certification of its catalytic concentration. The material can be used to verify the comparability of results from different laboratories, for intra-laboratory quality control, or for
Several factors may affect the delivery of a nebulized aerosol to the lung through an endotracheal tube during mechanical ventilation. To study these factors in vitro, a model representing ventilation of an adult patient was constructed by linking a Servo 900C ventilator to a standard humidified
To elucidate the formation of protein oxidation biomarkers alpha-aminoadipic semialdehyde (AAS) and gamma-glutamic semialdehyde (GGS) in food proteins was the main purpose of the present study. Food proteins, namely, myofibrillar proteins, alpha-lactalbumin, and soy proteins, as well as bovine serum
Binding of [125I-Tyr8]bradykinin (BK) was measured in homogenates of epithelial and smooth muscle layers of the guinea pig ileum. Binding assays were performed at 4 degrees C for 40 min (smooth muscle) or 90 min (epithelium) in 25 mM PIPES buffer at pH 6.8 in the presence of 1 mM
