Peripheral nerve injuries affect a large proportion of the global population, often causing significant morbidity and loss of function. Current treatment strategies include the use of implantable nerve guide conduits (NGC's) to direct regenerating axons between the proximal and distal ends of the nerve gap. However, NGC's are limited in their effectiveness at promoting regeneration Current NGCs...

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-specif...

not over conscientious in carrying out even those minutiae which they do understand. Bul^ for our own locally trained men most of whom have been many years with us, I must say that, with the introduction of high-pressure sterilisers, and a complete outfit in the way of operation coats, aprons, towels and rubber gloves, there has been corresponding carefulness in attending to the laws of surgica...

A prospective study of cervical cytology was carried out on 350 consecutive female patients attending the central venereal diseases clinic (CVDC) in Colombo, Sri Lanka. The main objective was to assess the proportion of abnormal cervical smears to emphasise the need to introduce routine cervical cytology screening in the sexually transmitted diseases (STD) clinics in Sri Lanka. Data about each ...

A simple and rapid flow system for the determination of lactulose in milk samples was developed. It is based on the hydrolysis of lactulose to galactose and fructose by the enzyme beta-galactosidase immobilised in a reactor. The amount of fructose produced was measured with an electrochemical biosensor based on the fructose dehydrogenase enzyme, K3[Fe(CN)6] as mediator and a platinum based elec...

It is generally considered that desert ecosystems release CO2 to the atmosphere, but recent studies in drylands have shown that the soil can absorb CO2 abiotically. However, the mechanisms and exact location of abiotic carbon absorption remain unclear. Here, we used soil sterilization, (13)CO2 addition, and detection methods to trace (13)C in the soil of the Mu Us Desert, northern China. After ...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

Abstract Objective Three-dimensional (3D) printing technology represents a novel method for manufacturing aligners. The aim of the present study was to assess in-vitro cytotoxicity 3D-printed aligners using different post-polymerisation conditions. Materials Aligners were printed same 3D-print resin (TC-85DAC, Graphy, Seoul, Korea) and printer (AccuFab-L4D, Shining 3D Tech. Co., Hangzhou, China...

There are different elements that contribute to good aseptic technique within the cleanroom and laboratory. One such element is donning of gloves (1), handling items appropriately, keeping regularly disinfected (2). Glove disinfection an essential step for bacteriological control, although how successful control maintained dependent upon type disinfectant (these generally alcohols gloved hands)...
