To evaluate the effectiveness of 50% Tricolored acetic acid (TCA) instillation in uterine cavity for treatment Abnormal bleeding (AUB). In this study, 40 patients with complaints menstrual bleeding, without any organic cause after ruling out malignancy were taken into consideration. After individually calculating volume TCA, it was instilled chemically ablation endometrium. a follow-up 3 months...

background: histamine is a food-borne chemical hazard which causes scombroid poisoning. the efficiency of histamine recovery from fish is greatly influenced by selection of an appropriate extraction solvent. hence, in this study the efficiency of different extraction solvents on recovery of histamine from fresh, frozen and canned fish was evaluated. methods: fresh, frozen and canned rainbow tro...

Klevas (1) determined dextran in blood by the Hagedorn-Jensen (2) copper reduction method, applied to filtrate prepared by the Somogyi technique (3), after acid hydrolysis of the filtrate for 6 hours. Hint and Thorsen (4) estimated dextran in blood by alkalinizing trichloroacetic acid filtrate, treating the filtrate with standard copper solution, and determining residual copper after 4 hours sh...

Trichloroacetic acid was found to be a convenient catalyst for the synthesis of 3,4-dihydropyrimidin-2-(1H)-ones and their corresponding 2(1H)-thiones through a one-pot three-component reaction of aldehydes, alkyl acetoacetate, and urea or thiourea at 70°C under solvent-free conditions.

ATP inactivated plant pyruvate dehydrogenase complex (PDC) from broccoli (Brassica oleracea) mitochondria. ATP inactivation of the complex was time-dependent and proportional to the ATP concentration. Time-dependent incorporation of (32)P from [gamma(32)P]ATP into trichloroacetic acid-precipitable protein corresponded to the inactivation of the PDC. It is concluded that plant PDC is phosphoryla...

A running colour electrophoresis of protein in sodium dodecylsulfate (SDS)-polyacrylamide gel (PAG) has been developed and the coloured gel was restained with silver nitrate and hydroquinone (HQ) within 20min. Trichloroacetic acid (TCA) was found to be a powerful destaining reagent and reproducibility of this double staining procedure was excellent.

* The trichloroacetic acid extracts were first acidified with sulfuric acid3 and kept overnight at 38” for decarboxylation of acetoacetate. The fluid was then neutralized with sodium hydroxide and phosphate, and the acetone distilled by the procedure of Folin.4 Acetone was determined calorimetrically by the method of Behre.6 Analogous results were obtained with the determination procedure of Le...
