In the present study, the effectiveness of Mimosa pudica tannins (MPT) in neutralizing the lethality of Naja kaouthia venom was compared with commercially derived tannins. Preincubation of MPT with N. kaouthia venom maintained 100% survival of mice after 24 hours. The mouse group in which there was no preincubation, no protection against the effects of the venom was observed. M. pudica tannin w...

Polystyrene (PS) polymer layers were prepared and studied as anti-corrosive barrier on both carbon steel zinc substrates. To increase the corrosion resistance of coatings, two different approaches considered: (i) use mesoporous silica-nanocontainers impregnated with a inhibitor (tannic acid) introduced into polystyrene matrix (ii) direct impregnation coatings same inhibitor. The nanocontainers ...

Tissue adhesives play an important role in surgery to close wounds, seal tissues, and stop bleeding, but existing adhesives are costly, cytotoxic, or bond weakly to tissue. Inspired by the water-resistant adhesion of plant-derived tannins, we herein report a new family of bioadhesives derived from a facile, one-step Michael addition of tannic acid and gelatin under oxidizing conditions and cros...

Microfibrils have been identified within and between corneal collagen lamellae in a number of vertebrate species in a variety of developmental and pathological conditions, but they are relatively rare in normal adult animals. The present study was undertaken to analyze corneal microfibrils in adult rabbits using enzymatic digestion techniques. Transmission electron microscopy (TEM) showed clust...

Toughening an epoxy resin by bio-based modifiers without trade-offs in its modulus, mechanical strength, and other properties is still a big challenge. This paper presents an approach to modify epoxy resin with tannic acid (TA) as a bio-based feedstock. Carboxylic acid-modified tannic acid (TA–COOH) was first prepared through a simple esterification between TA and methylhexahydrophthalic anhydr...

The details of the technique were given previously (Carson and Frisch, 1953) and consisted of the inoculation of standard amounts of influenza A virus (PR8 strain) into the allantoic cavity of 10 day old chick embryos. Thirty minutes later one to two mg of neutralized and filtered tannic acid were introduced and the fluids were harvested, tested for hemagglutination and for infectivity after st...
