OBJECTIVES The primary goal of this study was to assess the effect of postoperative hair-washing on incision infection and health-related quality of life (HRQOL) in craniotomy patients. The objectives of this study were to 1) determine the effect of postoperative hair-washing on incision infection and HRQOL, 2) provide evidence to support postoperative patient hygienic care, and 3) develop neur...
Remediation of heavy-metal-contaminated sediment is often hampered by the availability of heavy metals to the added chemical agents because the heavy metals are often shielded by the sediment matrix. Effective heavy-metal extraction technique becomes an important factor in enhancing the treatment efficiency. A novel extraction/washing technique utilizing chelating agent and elevated pressure in...
the present investigation was aimed at studying the effect of incubation period, media, vitamins and solvents on biotransformation of albendazole by cunninghamella blakesleeana. the transformation was evaluated and identified by high performance liquid chromatography (hplc) and the structures of the transformed products were assigned by liquid chromatography-tandem mass spectrometry (lc/ms/ms) ...
The scientific community is continuously developing new methods for the recovery and purification of water, since precious resources our planet are increasingly scarce we must work to save clean waters. One used use adsorbent absorbent materials that remove from water those substances harmful environment nanoclays. In this work, effect a nanoclay, specifically Halloysite, adsorb reactive dyes h...
Previous observational studies have reported protective effects of hand-washing in reducing upper respiratory infections, little is known about the associations between hand-washing and good hygienic habits and seasonal influenza infection. We conducted a case-control study to test whether the risk of influenza transmission associated with self-reported hand-washing and unhealthy hygienic habit...
This article explores factors that may influence hand washing behaviour among pupils and staff in primary schools. A qualitative process evaluation within a cluster randomized controlled trial included pupil focus groups (n = 16, aged 6-11 years), semi-structured interviews (n = 16 teachers) and observations of hand washing facilities (n = 57). Pupils and staff in intervention and control schoo...
INTRODUCTION Inadequate hand-washing facilities have been reported as a barrier to hand washing. This study aimed to evaluate the availability and accessibility of hand-washing facilities and supplies of hand-washing agents in the outpatient department (OPD) complex of a tertiary care teaching hospital. METHODOLOGY A checklist containing 13 variables was prepared and all rooms of direct patie...
We evaluated the microbial contamination of 17 types of vegetable and 10 types of fruit after 30-s washing with tap water with and without subsequent disinfection by 10-min immersion in 0.01% (100 ppm) sodium hypochlorite. The mean microbial contamination level of 9 types of leafy vegetable was 2.8 x 10(5) colony-forming units (CFU)/g after washing with water and 3.4 x 10(4) CFU/g after washing...
BACKGROUND More than 95% of neonatal deaths occur in developing countries, approximately 50% at home. Few data are available on the impact of hand-washing practices by birth attendants or caretakers on neonatal mortality. OBJECTIVE To evaluate the relationship between birth attendant and maternal hand-washing practices and neonatal mortality in rural Nepal. DESIGN Observational prospective ...
A study was conducted to develop a solvent system that will clean egg yolk samples and concentrate cholesterol oxides effectively before analysis. Cholesterol oxide standards or lipid samples (0.2 g) loaded onto a silicic column were washed with a portion of Solvent I (hexane/diethyl ether, 9:1, vol/vol) and then with Solvent II. Four different Solvent II preparations (Solvent IIa, hexane:ethyl...
