Methyl bromide is a highly toxic gas with poor olfactory warning properties. It is widely used as insecticidal fumigant for dry foodstuffs and can be toxic to central and peripheral nervous systems. Most neurological manifestations of methyl bromide intoxication occur from inhalation. Acute toxicity characterized by headache, dizziness, abdominal pain, nausea, vomiting and visual disturbances. ...

Bromides were formerly used for their sedative and anti-convulsant properties. The neuropsychiatric features of bromide intoxication have been recognized for many years (Barbour, Pilkington and Sargent, 1936). Carney (1971) described 5 cases of bromism and advocated stricter control on bromide preparations. Part III of the Medicine Act (1978) made potassium bromide available only by prescriptio...

X-ray absorption spectroscopy (XAS) has been used to unveil the bromide ion local coordination structure in 1-alkyl-3-methylimidazolium bromide [C(n)mim]Br ionic liquids (ILs) with different alkyl chains. The XAS spectrum of 1-ethyl-3-methylimidazolium bromide has been found to be different from those of the other members of the series, from the butyl to the decyl derivatives, that have all ide...

Circular dichroism in the 300-360 nm region and fluorescence induced by intercaltating binding of ethidum bromide to both DNA and RNA components were studied in isolated HeLa nucleoli. Both DNA and RNA compoents contribute to the induced dichroic elliticity. Digestion of nucleoli by RNase or DNase shows that most of the induced ellipticity comes from the DNA component. In nucleoli with an RNA/D...

Information regarding solute and water transport as affected by soil properties, topography, and climatic conditions is required to improve and validate transport models. This study evaluated the dissipation of bromide applied to the soil surface in the fall and spring to undisturbed (eroded) and rehabilitated landforms, in which topsoil was moved from depositional areas to the eroded upper slo...

The propellant-free Combivent Respimat Soft Mist Inhaler (CVT-R) was developed to replace the chlorofluorocarbon-propelled Combivent metered-dose inhaler (CVT-MDI). This steady-state pharmacokinetic (PK) substudy evaluated drug lung-delivery efficiency, using data from two phase III safety and efficacy trials. PK parameters were obtained from well-controlled population PK analyses. Area under t...

Cyclotropium bromide, a new antimuscarinic agent, inhibits gastrointestinal motility in animals at lower doses than those required to inhibit gastric acid secretion and salivation. In man, cyclotropium bromide suppresses fasting and meal stimulated colonic motility. This study investigated the effects of single oral doses of 60 mg cyclotropium bromide, 60 mg hyoscine N-butylbromide and placebo ...

Purpose We present a case report of a 44-year old female patient with complicated pneumonia who developed anisocoria after treatment with inhaled ipratropium bromide. Discontinuation of ipratropium bromide treatment led to complete resolution of anisocoria. Observation A 44-year old female patient was admitted to the Department of Pulmonology due to high body temperature (40.0 °C), coughing a...

The alkaline hydrolysis of two aromatic esters, 2-naphthyl acetate (2NA) and phenyl acetate (PhA) has been tackled in this work. The reaction has been followed in water and in the presence of cationic surfactants with different chain lengths: dodecyltrimethylammonium bromide (DTABr), tetradecyltrimethylammonium bromide (TTABr), and hexadecyltrimethylammonium bromide (CTABr) and the correspondin...

a corresponding flux from the ocean to the atmosphere. This effect might lessen or negate the benefits to stratospheric ozone from a reduction in anthropogenic emissions of methyl bromide. In terms of costs to society from the ban, the California Department of Pesticide Regulation estimates growers in its state stand to lose $340 million per year in crop damage. Duafala says no single alternati...
