The purpose of this study was to examine our hypotheses that BoTA provide protection of musculocutaneous flap from ischemia-reperfusion injury.

    Method: Five days after pretreatment injection (BoTA versus normal saline), a right superior musculocutaneous flap (6 × 1. Read More

    Botulinum neurotoxin (BoNT) is a highly potent and lethal toxin, which even in minute quantities can lead to death. BoNT occurs in seven well described serotypes, A-G, and it is critical to not only detect the presence of BoNT, but also to determine the serotype to which a person has been exposed, as the degree of toxicity and persistence of symptoms varies greatly between the various types. Recently, Conway et al. Read More

    Clinical study of botulinum toxin A injection combined with spasmodic muscle therapeutic instrument on lower limb spasticity in patients with stroke.

    Objective: Current pharmacological agents used to treat Parkinson disease (PD) tremor and essential tremor (ET) provide suboptimal benefit and are commonly associated with significant adverse effects. Botulinum toxin type A (BoNT-A) has been shown to be effective for wrist tremor though functionally bothersome muscle weakness frequently occurs. This is the longest study to date demonstrating that BoNT-A therapy coupled with kinematic guidance can provide efficacious outcomes for upper limb tremor with minimized unwanted weakness. Read More

    Side effects and potential risk factors of botulinum toxin type A intramuscular injections in knee flexion contractures of hemophiliacs.

    Introduction: Knee flexion contracture (KFC) is a common complication of recurrent hemarthrosis in children and young adults with hemophilia. If the KFC is not prevented (by means of primary prophylaxis) and treated properly and early (be means of physical medicine and rehabilitation), it will become fixed. Areas covered: The aim of this article is to review the potential role of botulinum toxin type A (BTX-A) intramuscular injections for the treatment of KFC in people with hemophilia (PWH). Read More

    Deubiquitinating enzyme VCIP135 dictates the duration of botulinum neurotoxin type A intoxication.

    Botulism is characterized by flaccid paralysis, which can be caused by intoxication with any of the seven known serotypes of botulinum neurotoxin (BoNT), all of which disrupt synaptic transmission by endoproteolytic cleavage of SNARE proteins. BoNT serotype A (BoNT/A) has the most prolonged or persistent effects, which can last several months, and exerts its effects by specifically cleaving and inactivating SNAP25. A major factor contributing to the persistence of intoxication is the long half-life of the catalytic light chain, which remains enzymatically active months after entry into cells. Read More

    The effect of botulinum toxin A (Botox) injections used to treat limb spasticity on speech patterns in children with dysarthria and cerebral palsy: A report of two cases.

    Botulinum toxin A (Btx-A) injections are used to treat limb spasticity in children with cerebral palsy (CP) resulting in improved gross and fine motor control. This treatment has also been reported to have additional functional effects, but the effect of treatment on speech has not been reported. This report presents results of longitudinal speech evaluation of two children with CP given injections of Btx-A for treatment of limb spasticity. Read More

    Rapid and sensitive detection of botulinum neurotoxins (BoNTs), which cause botulism, is essential in a public health emergency or bioterrorism event. We have previously developed a mass spectrometry (MS)-based functional method, Endopep-MS assay, for the fast detection and differentiation of all BoNT serotypes by affinity enriching the toxin and detecting the serotype-specific cleavage products of peptide substrates derived from the in vivo targets. To improve the performance of the Endopep-MS assay, we report here the further optimization of the peptide substrate for the detection of serotype A botulinum neurotoxins. Read More
