Widespread Evolution of Molecular Resistance to Snake Venom α-Neurotoxins in Vertebrates

open access: yesToxins, 2020
Venomous snakes are important subjects of study in evolution, ecology, and biomedicine. Many venomous snakes have alpha-neurotoxins (α-neurotoxins) in their venom.

Botulinum toxins and fillers for treatment of the aging face

open access: yesTNOA Journal of Ophthalmic Science and Research, 2017
We present a comprehensive review of how to best use neuro-toxins and fillers to rejuvenate the aging face. With modern neuro-toxins and fillers, it is now possible to achieve an improvement in the aging changes of young, middle-aged, and older patients.

Tables of Toxicity of Botulinum and Tetanus Neurotoxins

open access: yesToxins, 2019
Tetanus and botulinum neurotoxins are the most poisonous substances known, so much so as to be considered for a possible terrorist use. At the same time, botulinum neurotoxin type A1 is successfully used to treat a variety of human syndromes ...

Availability of Guanitoxin in Water Samples Containing Sphaerospermopsis torques-reginae Cells Submitted to Dissolution Tests

open access: yesPharmaceuticals, 2020
Guanitoxin (GNT) is a potent neurotoxin produced by freshwater cyanobacteria that can cause the deaths of wild and domestic animals. Through reports of animal intoxication by cyanobacteria cells that produce GNT, this study aimed to investigate the bio ...

Scallop genome reveals molecular adaptations to semi-sessile life and neurotoxins

open access: yesNature Communications, 2017
Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior are well recognized, but the underlying molecular mechanisms are largely unknown.

Quantitative Mass Spectrometry for Bacterial Protein Toxins — A Sensitive, Specific, High-Throughput Tool for Detection and Diagnosis

open access: yesMolecules, 2011
Matrix-assisted laser-desorption time-of-flight (MALDI-TOF) mass spectrometry (MS) is a valuable high-throughput tool for peptide analysis. Liquid chromatography electrospray ionization (LC-ESI) tandem-MS provides sensitive and specific quantification of
