This paper reviews the current and most neurological (central nervous system, CNS) uses of the botulinum neurotoxin type A. The effect of these toxins at neuromuscular junction lends themselves to neurological diseases of muscle overactivity, particularly abnormalities of muscle control. There are seven serotypes of the toxin, each with a specific activity at the molecular level. Currently, ser...

introduction: submucoperichondrial injection of botulinum neurotoxin a (bta) in the nasal septum is a promising therapeutic option in the treatment of persistent allergic rhinitis (ar) and non-allergic rhinitis, and is safer and more effective than intraturbinate injection in reducing clinical symptoms.   materials and methods: forty patients diagnosed with persistent ar or non-allergic rhiniti...

Clostridium botulinum strain Osaka05, which has been isolated from an infant patient with botulism in Japan, is the first strain producing botulinum neurotoxin subtype B6. Here, we report the draft genome sequence of C. botulinum Osaka05.

objective botulism is the acute, descending, flaccid paralysis that results when the neurotoxin of clostridium botulinum blocks neuromuscular transmission. c botulinum toxin is the most poisonous substance that blocks neuromuscular transmission and causes death through airway and respiratory muscle paralysis; all forms of botulism manifest neurologically as asymmetric, descending, flaccid paral...

Botulinal neurotoxin continues to be a concern in food safety. The molecular biology of botulinal neurotoxin gene expression in Clostridium botuli-num is poorly understood. In this study, the transcriptional and translational kinetics of expression of type A botulinal neurotoxin by C. botulinum type A strains Hall A, 62A, and NCTC 2916 were determined during 96 hours of growth. Strains were gro...

When the presynaptic membrane protein syntaxin is coexpressed in Xenopus oocytes with N- or P/Q-type Ca(2+) channels, it promotes their inactivation (Bezprozvanny et al., 1995; Wiser et al., 1996, 1999; Degtiar et al., 2000) (I. B. Bezprozvanny, P. Zhong, R. H. Scheller, and R. W. Tsien, unpublished observations). These findings led to the hypothesis that syntaxin influences Ca(2+) channel func...

OBJECTIVE The aim of this article is to review the mechanism of action, physiological effects, and therapeutic applications of botulinum neurotoxins in the head and neck area. STUDY DESIGN An extensive literature search was performed using keywords. The resulting articles were analyzed for relevance in four areas: overview on botulinum neurotoxins, the role of botulinum neurotoxins in the man...

Cervical dystonia is the most common form of focal dystonia characterized by involuntary muscle contractions causing abnormal movements and posturing of the head and neck and is associated with significant pain. Botulinum toxin is considered first-line therapy in the treatment of pain and abnormal head posturing associated with cervical dystonia. There are currently three botulinum toxin type A...
