Public Health Burden of Botulinum Neurotoxicity: A Research Perspective to Evaluate the Antitoxin Efficacy of Thearubigin Extract of Black Tea

Botulinum toxin (BoNT), being the most poisonous substance poses a great threat to global public health as a deadly bio-weapon. BoNT/A, BoNT/B and BoNT/E serotype toxicity cause flaccid paralysis in human by blocking neurotransmitter activity. Thearubigin, a black tea extract is found to be effective in neutralizing BoNT when experimented with animal models. This hypothesis opens a new frontier...

Antipruritic Effects of Botulinum Neurotoxins.

This review explores current evidence to demonstrate that botulinum neurotoxins (BoNTs) exert antipruritic effects. Both experimental and clinical conditions in which botulinum neurotoxins have been applied for pruritus relief will be presented and significant findings will be highlighted. Potential mechanisms underlying antipruritic effects will also be discussed and ongoing challenges and unm...

THE GREEN SYNTHESIS OF GOLD NANOPARTICLES USING THE ETHANOL EXTRACT OF BLACK TEA AND ITS TANNIN FREE FRACTION

Abstracts: nanoparticles. All the extracts were used separately for the synthesis of gold nanoparticles through the reduction ofaqueous AuClgold ions to gold nanoparticles. The ethanol extract of black tea and its tannin free ethanol extract produced goldnanoparticles in the size ranges of 2.5-27.5 nm and 1.25-17.5 nm with an average size of 10 nm and 3 nm, respectively.The prepared colloid gol...

Central effects of tetanus and botulinum neurotoxins.

Tetanus neurotoxin (TeNT) and botulinum neurotoxins (BoNTs; from A to G) are metalloproteases that act on nerve terminals to prevent exocytosis. They are extensively exploited for the study of cellular physiology. Moreover, BoNTs are also employed in clinical neurology for the treatment of several disorders characterized by hyperexcitability of peripheral nerve terminals. This review summarizes...

Effect of Iranian Black Tea Extract and Its Isolated Thearubigins on Intestinal Transit Time in Mice

Introduction: In this study, the effects of black tea extract of Iranian tea plant (Camellia sinensis var sinensis) and its polyphenolic pigment thearubigins were investigated on mice intestinal transit time. Method: Thearubigins were isolated by liquid-liquid fraction method. The effects of black tea extract and isolated thearubigins on intestinal propulsion were measured by charcoal propulsio...
