OBJECTIVE There is uncertainty regarding the safety of surgical antiseptic preparations in the ear. A systematic review of the literature was conducted to assess the evidence regarding ototoxicity of surgical antiseptic preparations. METHODS A literature search was conducted using the PRISMA methods. Key words included "ototoxicity" "hearing loss", "antiseptic", "surgical preparation", "tympa...

Antimicrobial liquids and foams were applied to the hands to determine their virucidal activity against rhinoviruses. Dilute solutions (1%) of iodine in ethyl alcohol or in water were most effective in causing inactivation of rhinovirus when applied immediately after viral contamination. Iodine also had a residual virucidal activity which persisted on the hands for up to 1 h. Less effective ina...

Automated chemical analysis was applied to constant in-vivo experiments on dogs for the determination of blood alcohol. The continuous blood collection was similar to that in earlier experiments for determination of blood glucose in humans. Although interferences by glucose was observed in the chemical methodology used, preliminary data show that the rise of blood alcohol is slower following t....

alcohol oxidation is an important reaction in organic syntheses. some of these reactions must beunder difficult conditions in respect of high temperature and pressure. in many cases, reactions areconducted by environmentally in appropriate solutions. in this study, preparing an effectivenanocatalyst and estimating the optimum provisions of its production processes are assessed. twomajor and cru...

In fact alcohol is a toxic substance that has a direct effect on brain. Some of the most common mental disorders due to alcohol abuse are: Memory disorder: Hazardous amounts of alcohol may cause intoxication, impairment of memory so that the person who took a drunken accident may not remember the event. Periods of memory impairment in those with a history of alcohol addiction would also happen ...

Background: World Health Organization report in 2014 indicates a considerable range of alcohol consumption across the world which had a growing trend during last 5 years. A study on 5,231 students in 57 universities has shown that alcohol consumption became more common than other drugs, and alcohol is in the first rank for repeated usage. In another study in 2010, the prevalence of alcohol use ...

PURPOSE To evaluate the size and shape of commercially available polyvinyl alcohol (PVA) particles and to determine whether they change in size when suspended in nonionic contrast and in a solution of nonionic contrast and absolute alcohol. METHODS The two-dimensional area and the long and short axis of PVA particles from several different vendors were measured using a light microscope attach...

Recent reports suggest that dietary ethanol, or alcohol, is a supplemental source of calories for some primates. For example, slow lorises (Nycticebus coucang) consume fermented nectars with a mean alcohol concentration of 0.6% (range: 0.0-3.8%). A similar behaviour is hypothesized for aye-ayes (Daubentonia madagascariensis) based on a single point mutation (A294V) in the gene that encodes alco...
