1. Four of the known components of wall preparations of vegative cells of Bacillus licheniformis N.C.T.C. 6346 have been isolated free of each other after successive treatments of the walls with trichloroacetic acid and lysozyme: (a) a mucopeptide consisting of glucosamine, muramic acid, alphain-diaminopimelic acid, glutamic acid and alanine in the molar proportions 1.0:0.8:1.0:1.2:1.7; (b) an ...

Objective: To compare the effects of 35% Glycolic acid (GA) peel versus 15% Trichloroacetic Acid (TCA) in patients primed with 4% Hydroquinone and sunblock for Melasma treatment.
 Study Design: Quasi-experimental stud.
 Place Duration Study: Department Dermatology, Combined Military Hospital, Jhelum Pakistan, from Jul to Nov 2020.
 Methodology: Forty-eight melasma were included d...

The uptake of cholesterol from high-density lipoproteins (HDL) labeled with 125I and [3H]cholesterol was examined in cultured rat luteal cells. Luteal cells were incubated with labeled HDL, following which the metabolic fate of the apolipoproteins and cholesterol moieties of the receptor-bound HDL were examined. About 50% of the originally bound HDL apolipoproteins were released into the medium...

The health risks of twenty five workers exposed to trichloroethylene in three factories were studied. Trichloroethylene in the breathing zone of the workers was collected for a full shift following the NIOSH method number 1022 and urine samples were also collected for analysis of trichloroacetic acid metabolite by Gas Chromatography/Mass Spectrometry. The results showed that average concentrati...

Background: Several regimens of therapy were recommended for the treatment of genital wart with different efficacies. The purpose of this study was to compare the efficacy of podophylin 20% versus trichloroacetic acid 30% in the treatment of genital wart.Methods: This randomized clinical study was conducted on 120 cases with genital wart. They randomly received podophylin 20% or trichloroacetic...

In mixtures of trichloroacetate ion and trichloroacetic acid in acetonitrile, trichloromethyl radicals are produced as a result of the redox reaction between the acid and its conjugate base. The reaction follows a loop mechanism in which the trichloroacetic acid is slowly consumed by proton reduction while the trichloroacetate ion is oxidized like in an electrochemical Kolbe reaction. The hydro...

An extraction method is described for quantitatively determining Mg, K, Na, 2n, and Mn in plant tissues. The tissue is extracted with 2% trichloroacetic acid and the elements are determined on the filtrate by atomic absorption spectrophotometry. Results compare favorably with those determined after wet ashing with nitric and perchloric acids. In addition, trichloroacetic acid extracts the same ...

The most popular pretreatment method of plasma samples for the measurement of ascorbate (AsA) and dehydroascorbate (DHA) has been an acidic deproteinization via metaphosphoric acid or trichloroacetic acid. In general, DHA is absent in plasma samples prepared from human blood in a conventional manner. However, when these plasma samples were subjected to acidic deproteinization, DHA was detected ...
