THE behaviours of protein solutions when filtered through membranes of graded porosities under different conditions of PH and dispersion medium have been further studied in the case of haemocyanin (Helix pomatia), edestin and egg albumin. The particle sizes of these proteins in dilute solution have been determined by Svedberg and his co-workers by the method of ultracentrifugal analysis, the re...

This epidemiological study was of 18,728 employees at 14 United States facilities producing sterilised medical supplies and spices, who were potentially exposed to ethylene oxide (EO) for at least 90 days. The mortality of the cohort was studied to the end of 1988. A total of 1353 deaths was identified. The cohort had a significantly lower mortality than the general population from all causes, ...

OBJECTIVE An initial audit was conducted in 2001 to monitor all women referred for female sterilisation. This re-audit in 2003 set out to investigate those women who initially chose alternative reversible contraception and ascertain whether they were still using that method or if they or their partner had requested sterilisation. METHODS A telephone survey of general practitioners was conduct...

This paper describes a model and simulation of heat transfer and mass transport phenomena during digestion process of oil palm fruits using Comsol Multiphysics software ver. 4.4. Prior to the simulation, some experimental works were conducted to measure water and oil transport and heat transfer. The measured average water diffusivity coefficients of sterilised oil palm fruits were 3.03E-09 m/s,...

The worst fear of a joint replacement surgeon is infection. Many factors are known to contribute to the development of infection in a surgical set-up. Post-operative wound soakage is one of them. Wet wounds lead to repeated dressing, exposing the wound for contamination, risk of infection and increased length of hospital stay (1). Therefore any attempt to avoid this scenario is desirable. We re...

OBJECTIVES To perform a pilot study on bacterial contamination in some dental surgeries (n=51) in a local health unit in Brescia (Lombardy Region, Italy) and to evaluate the procedures to control cross infection used by the personnel to reduce the risk of infection in dental practice. METHODS A survey was carried out by interviewing 133 dental personnel with a questionnaire on the procedures ...

OBJECTIVE To report the use of three dimensional (3D) computed tomographic (CT) imaging, computer simulation and rapid prototype modelling to aid surgical correction of a complex antebrachial deformity in a dog. METHODS A six-year-old, 13 kg spayed female Chihuahua crossbreed dog was presented for worsening forelimb gait and exercise intolerance. Both forelimbs had gross angular limb deformit...

In vitro propagation through nodal explants by indirect organogenesis of Clinacanthus siamensis Bremek. Nodal segments were surface sterilised in NaOCl for 5 min. This is followed by treating it with 0.1% Hgcl2 for 8 min. Different concentrations of BAP and 2P were added to full strength MS medium for culture initiation. Multiple shoots were formed in MS medium augmented with various concentrat...

OBJECTIVES To assess whether cancer incidence, mainly from lymphohaematopoietic tumours and breast cancer, and mortality were increased in a cohort of Swedish sterilant workers exposed to low levels of ethylene oxide (EtO), updated with 16 more years of follow up. METHODS The mortality and cancer incidence 1972-2006 experienced by a cohort of 2,171 male and female workers employed for at leas...

Background—Published estimates of the prevalence of postcholecystectomy diarrhoea derive from retrospective or uncontrolled data. They ignore functional bowel syndromes and possible changes in diet and drug use. Aims—To determine prospectively whether and how often cholecystectomy leads to changes in bowel function and bowel symptoms, especially to liquid stools, over and above any non-specific...
