In a field trial of three disinfectant-detergent preparations for the surgical scrub Hibiscrub (a 4% chlorhexidine detergent solution) maintained a significantly greater residual antibacterial action on the skin of the gloved hands of an operating team than was obtained with Disadine (povidone-iodine detergent preparation) (P<0.001). In comparison with Phisohex (3% hexachlorophane in detergent ...

It is demonstrated that proteins and nucleic acids can be transported through hydrophobic organic solvents (liquid membranes) via nonspecific complex formation with detergents, whereas no macromolecule transport is observed without the latter. A protein (or a nucleic acid) first interacts with an oppositely charged detergent due to hydrophobic ion pairing in the aqueous feed phase. The resultan...

Mycoplasma hyorhinis has been shown to induce the secretion of tumor necrosis factor alpha (TNF-alpha) from monocytes. To identify the molecules responsible for this activity, we separated sonicated M. hyorhinis lysate material by centrifugation at 100,000 x g into soluble (S) and particulate (P) fractions. The fractions were assayed for TNF-alpha-inducing activity by the L929 bioassay. Both th...

A 42-year-old woman with a history of depression and epilepsy ingested two types of household detergent and developed gastrointestinal symptoms, and subsequently acute renal failure. Coingestants included nontoxic quantities of paracetamol and therapeutic doses of sodium valproate and fluoxetine. The patient developed acute renal failure, and also had fever and unilateral ear inflammation. The ...

We have found that treatment of the photosynthetic membranes of green plants, or thylakoids, with the nonionic detergent Triton X-114 at a 10:1 ratio has three effects: (a) photosystem I and coupling factor are solubilized, so that the membranes retain only photosystem II (PS II) and its associated light-harvesting apparatus (LHC-II); (b) LHC-II is crystallized, and so is removed from its norma...

This paper utilizes cyclodextrin-based host-guest chemistry in a microfluidic device to modulate the crystallization of membrane proteins and the process of concentration of membrane protein samples. Methyl-beta-cyclodextrin (MBCD) can efficiently capture a wide variety of detergents commonly used for the stabilization of membrane proteins by sequestering detergent monomers. Reaction Center (RC...

OBJECTIVE Laundry detergent pods are a new product in the US marketplace. This study investigates the epidemiologic characteristics and outcomes of laundry detergent pod exposures among young children in the United States. METHODS Using data from the National Poison Data System, exposures to laundry detergent pods among children younger than 6 years of age during 2012-2013 were investigated. ...
