Screening a library of drugs with known safety profiles in humans yielded 30 drugs that reliably protected mammalian neurons against glucose toxicity. Subsequent screening demonstrated that 6 of these 30 drugs increase lifespan in C. elegans: caffeine, ciclopirox olamine, tannic acid, acetaminophen, bacitracin, and baicalein. Every drug significantly reduced the age-dependent acceleration of mo...

Treatment of sheep erythrocytes with suitable concentrations of tannic acid render them capable of adsorbing certain protein molecules from solution in saline. Red cells which have adsorbed proteins in this way are agglutinated after washing by the homologous antiprotein sera, even by high dilutions. Through hemagglutination sera can be titrated for antibodies against antigens adsorbed on the c...

Arresting Caries Treatment (ACT) has been proposed to manage untreated dental caries in children. This prospective randomized clinical trial investigated the caries-arresting effectiveness of a single spot application of: (1) 38% silver diamine fluoride (SDF) with tannic acid as a reducing agent; (2) 38% SDF alone; (3) 12% SDF alone; and (4) no SDF application in primary teeth of 976 Nepalese s...

−− Clarification of apple juice by flocculation and precipitation with bentonite and gelatin is explained on a more systematic basis, essentially through the determination of turbidity and zetapotential. Apple juice was also treated with Polyvinylpolypyrrolidone (PVPP) to remove total polyphenol. Gelatin-particle complex was evaluated as the increase in juice turbidity after the adding of tanni...

In foods, tannins are considered nutritionally undesirable. Spectrophotometric methods have been used to detect tannin degradation by L. plantarum strains isolated from food substrates. Enzymatic degradation of tannic acid by L. plantarum CECT 748T was examined in liquid cultures and in cell-free extracts by HPLC. Significative reduction of tannic acid was not observed during incubation in the ...

To ilic Editor, The Indian Medical Gazette. Sir,?During the past few years, tannic acid has come into considerable vogue for the treatment of burns. As House Surgeon in the Sir J. J. Hospital in Bombay in 1927-28 I had to treat many cases of burns, but was unsuccessful with tannic acid. I asked my chief, Mr. S. R. Moolgavkar, f.r.c.s., as to the reason for this, and he gave me the following adv...

Fixation of HeLa cells with a mixture of 100 mM glutaraldehyde, 2 mg/ml tannic acid and 0.5 mg/ml saponin allows the tannic acid to penetrate intact cells without disruption of membranes or extraction of the cytoplasmic matrix. After subsequent treatment with OsO4 cytoplasmic structures are stained so densely that fine details are visible even in very thin (dark gray) sections. Actin filaments ...

properties of these materials. Investigations of dye adsorpThe effects of tannic acid and Rhodamine B on the zeta potention on the materials and the electrical and thermodynamic tials and surface free energy components of polyester fabric (Daproperties of the fiber/solution interface are fundamental for cron 54, Style 777) were studied. Knowledge of these parameters understanding the dyeing mec...

The antioxidant potential of the 99% methanolic extract of leaves of Muntingia calabura was assessed by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and total phenolic content was measured by Folin-Ciocalteau (FC) by Singleton and Rossi using Gallic acid and Tannic acid as the calibration standard. Moreover Muntingia calabura leaf extract showed strong reducing power and significant antioxidant a...

Quality changes of Eastern little tuna (Euthynnus affinis) slices treatedwith caffeic or tannic acid (0.2 g kg 1) and the control during 15 days of refrigerated storage in air or under modified atmospheric packaging (MAP: 60% CO2, 35% N2, 5% O2) were studied. Tannic acid exhibited a greater preventive effect on metmyoglobin (metMb) formation and lipid oxidation than did caffeic acid (P < 0.05)....
