The present study aimed to assess whether arterial carbon dioxide pressure (Pa,CO(2)) has an impact on agreement between oxygen saturation measured with pulse oximetry (Sp,O(2)) or arterial blood gas co-oximetry (Sa,O(2)). Sa,O(2) and Sp,O(2) determinations were obtained simultaneously from 846 patients under assessment for long-term home oxygen therapy in a specialised outpatient clinic. Both ...

An extracellular cold active lipase from Pseudomonas sp. VITCLP4 was concentrated by two methods, ammonium sulphate precipitation and ultrafiltration. Ammonium sulphate precipitation with 40% saturation was found to give good results with 125-fold partially purified lipase and yield of 63%. Further purification by DEAE-Sephadex ion exchange chromatography resulted in 4.6-fold purified enzyme wi...

BACKGROUND Previous studies report association of contraceptives with moderate increase in urinary tract infection among sexually active premenopausal women. The aim of our study was to find out whether the use of hormonal contraceptives has any effect on microbiota of the vagina in the contraceptives users in Khairpur Sindh Pakistan. METHODS A prospective study in woman population of Khairpu...

BACKGROUND Prohepcidin is one of the regulators of iron metabolism. Few studies examined its relation with solid tumors (ST), inflammatory bowel disease (IBD) and iron deficiency anemia (IDA) in children. METHODS We measured serum prohepcidin (SP), soluble transferrin receptor (sTfR), serum ferritin (SF), serum iron (SI), transferrin saturation (TS), erythrocyte sedimentation rate (ESR) and C...

The pollen spectra of honey samples collected in five apiaries situated near cerrado areas in Minas Gerais State, Brazil, were studied from April 1996 to April 1998 in order to establish the contribution of different plant species in pollen or nectar production The honey samples were characterized by the following native species: Astronium sp., Alternanthera sp., Schinus sp., and Serjanea sp. T...

OBJECTIVE To reduce hyperoxia in very low birth weight infants who receive supplemental oxygen, the Children's Mercy Hospital neonatal respiratory quality improvement committee introduced the potentially better practice of oxygen saturation targeting and identified strategies to overcome barriers to implementation of this practice. METHODS Using rapid-cycle quality improvement projects, this ...

We examined the axial repeats in electron micrographs of three types of negatively stained paracrystals (two tactoid- and one sheet-like type) of rabbit light meromyosin (LMM) and its complex with C-protein characterized previously by similar axial period of about 43.0 nm. Assuming for the axial repeat in type II tactoids the value of 42.93 +/- 0.05 nm as it was determined by X-ray diffraction ...

Multiple sclerosis (MS) is postulated to be a T cell-mediated autoimmune disease characterized clinically by a relapsing-remitting (RR) stage followed by a secondary progressive (SP) phase. The progressive phase is felt to be secondary to neuronal degenerative changes triggered by inflammation. The status of the innate immune system and its relationship to the stages of MS is not well understoo...

The present study focus on the biodegradation of trinitrotoluene (TNT) by Bacillus sp. YRE1 isolated from red effluent in free state and also cells immobilized on charcoal and polystyrene. TNT degradation was monitored weekly for 168 hours, at 262 nm. Immobilized Bacillus sp. YRE1 was checked for its ability to degrade TNT by exposing it to different temperatures. It was found that both charcoa...

Methods 60 patients with L5-S1 isthmic spondylolisthesis (mean age, 47years, range, 28 to 69 years) and age-matched control group of 77 normal adults (mean age, 43.5 years, range, 25 to 63 years) were recruted in this retrospective study. Parameters including slip distance (SD), slipping percentage (SP), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), L5 incidence (L5I), lumbar-sacr...
