background: acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases.the peeling method has been recently found to be effective for acne treatment. this study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. materials and methods: in a prospective single?blin...

BACKGROUND According to Warburg's effect, the rate of glycolysis increases in cancerous cells. This will increase overall levels of pyruvic acid. The present on-going study was conducted to estimate the levels of pyruvic acid in saliva and serum in normal, oral PMD subjects. MATERIAL AND METHODS A total of 50 subjects in healthy, PMD of the oral cavity individuals were selected based on clini...

Pyruvic acid is a normal intermediary of carbohydrate metabolism (1, 2). It has been previously demonstrated that thiamin, or more particularly thiamin pyrophosphate (cocarboxylase), is concerned in the normal catabolism of pyruvic acid (1). In Oriental beri-beri (3) and peripheral neuropathy in the alcohol addict (4)-both diseases associated with a deficiency of thiaminhyperpyruvemia does occu...

Malic enzyme [L-malate: NAD(P)(+) oxidoreductase (EC 1.1.1.39)] catalyzes the oxidative decarboxylation of L-malic acid to produce pyruvic acid using the oxidized form of NAD(P) (NAD(P)(+)). We used a reverse reaction of the malic enzyme of Pseudomonas diminuta IFO 13182 for HCO(3)(-) fixation into pyruvic acid to produce L-malic acid with coenzyme (NADH) generation. Glucose-6-phosphate dehydro...

Thiamine deficiency in all species thus far studied affects the metabolism of pyruvic acid. The lacki until quite recently (l), of a rapid specific method for estimating pyruvic acid necessitated the use of the rapid but less specific technique introduced by Clift and Cook (2). Occasionally it has been estimated by isolation as the 2,4-dinitrophenylhydrazone, by the method of Case (3) or a modi...

a preliminary study on statistical modelling of a process for depolymerisation of cassava non-starch carbohydrate using halide salt assisted phosphoric and pyruvic acids were accomplished. the effects of three independent variables namely; acid concentration, potassium iodide salt and duration were studied using the central composite rotatable design on hydrolysis of the cassava non-starch carb...

The temporal degradation of the Belousov-Zhabotinskii substrates lactic acid, pyruvic acid, bromoand dibromo pyruvic acid is investigated. The only final product of non-brominated substrates is acetic acid. From brominated educts only brominated acetic acids result. The con­ centrations of the stable products are determined as a function of time. The gross reactions are mainly based on simple c...

Sputum culture for tubercle bacilli on a solid egg medium containing glycerol was compared with culture on a similar medium containing pyruvic acid and no glycerol. Tubercle bacilli from the sputum of five out of 99 patients grew on pyruvic acid medium but not on glycerol medium. The addition of pyruvic acid is therefore essential when an egg medium is used for the cultural diagnosis of tubercu...
