Tracheal ultrasonography was performed to measure the width of the tracheal ring shadow and to assess the clinical relevance of these measurements for identifying tracheal collapse. The first tracheal ring width (FTRW) and thoracic inlet tracheal ring width (TITRW) were measured on both expiration and inspiration. The mean of the FTRW width (129 dogs) was greater in expiration (10.97 plusmn; 1....

We investigated whether the oxygen affinity of lamprey haemoglobin decreases with increasing oxygen concentration at the high (10­25 mmol l-1 monomeric) haemoglobin concentrations prevailing within the erythrocytes. The intracellular concentration of haemoglobin was experimentally adjusted by shrinking the cells osmotically: the osmolality of the equilibration medium was increased from appr...

The electrometric [Delta]pH method and an in vitro radioisotopic HCO3- dehydration assay were used to demonstrate the presence of true extracellular carbonic anhydrase (CA) activity in the blood of the Pacific spiny dogfish Squalus acanthias. An extracorporeal circulation and stopflow technique were then used to characterise the acid­base disequilibrium in the arterial (postbranchial) blood...

BACKGROUND Bisphenol A (BPA) is an endocrine-disrupting chemical that may contribute to development of obesity and metabolic disorders. Humans are constantly exposed to low concentrations of BPA, and studies support that the developmental period is particularly sensitive. OBJECTIVES The aim was to investigate the effects of low-dose developmental BPA exposure on metabolic parameters in male a...

The aim of the research was to investigate antibacterial activities and phytochemical properties aqueous ethanolic extracts Mango (Mangifera indica) Neem (Azadirachta leaves, on clinical isolates Salmonella typhi, paratyphi A, B C, in Lafia, Nigeria. agar well diffusion technique used analyses were done triplicates. At highest extract concentration 80 mg/ml, S. showed inhibition zones 29.4&plus...

A method based on X-ray microanalysis (XRMA) with the transmission electron microscope for measurement of total amounts of elements in single microbial cells has been developed. All major elements in cells except hydrogen can be measured simultaneously. XRMA provided N/C ratios (means (plusmn) standard errors of the mean) for stationary-phase and growing Escherichia coli of 0.23 (plusmn) 0.01 a...

PURPOSE To compare the stone clearance times in patients undergoing extracorporeal shock wave lithotripsy (SWL) or retrograde intrarenal surgery (RIRS) for single radiopaque renal pelvis stones 10-20 mm in size. The results of this study may guide urologists and patients and aid in selecting the optimal preoperative treatment. MATERIALS AND METHODS Between January 2013 and February 2015, we c...

OBJECTIVE To evaluate the effect of home-use bleaching agent containing 16% Carbamide Peroxide (CP) and in-office bleaching agent containing 38% Hydrogen Peroxide (HP) on enamel micro-hardness. STUDY DESIGN An in vitroexperimental study. PLACE AND DURATION OF STUDY Department of Operative Dentistry and Science of Dental Materials at Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences,...

Glucose plays a fundamental role in mammalian energetics but its contribution as a metabolic fuel is not well established for fish; the accurate in vivo measurement of glucose flux is essential to determine the importance of this substrate in the energy budget of teleosts. Therefore, the goal of the present study was to verify the reliability of the continuous tracer infusion method for estimat...

Over the years, snacking has become a regular habit for majority of population with increasing need food manufacturers to meet consumers’ demand through product development. In this study, snack bars were prepared using maize and Bambara nuts mixed in following ratios: A, 100% maize; B, nuts; C, 50% maize: D, 75% 25% E, nuts: maize. The total heterotrophic bacterial count samples A E was ...
