AIMS To determine if the outcomes of intradetrusor botulinum toxin A (BTX-A) injections for the management of refractory overactive bladder (OAB) symptoms are different if performed due to lack of anticholinergic efficacy versus medication intolerability. METHODS Retrospective chart review was performed on all patients undergoing intradetrusor BTX-A (BOTOX®, Allergan Inc., Irvine, CA) injecti...

The systematic literature review was carried out to point out the efficacy of botulinum type A toxin (BTX-A) intra-detrusor injections in adults with idiopathic overactive bladder (OAB) and urgency urinary incontinence (UUI). A PubMed search for clinical studies with BTX-A intra-detrusor injections in adults with OAB was performed.The studies showed improvements in quality of life by relieving ...

BACKGROUND Many previous studies have demonstrated that botulinum toxin A (BTX-A) injections satisfactorily reduce spasticity. Nevertheless, BTX-A, with or without an adjuvant therapy, effectively improves the direct functional movement in few patients with spastic upper extremity paralysis. Therefore the present study aimed to determine the effectiveness of task-orientated therapy on spasticit...

INTRODUCTION Botulinum toxin A (BTX-A) is a neurotoxin that inhibits acetylcholine release by cleaving cytosolic synaptosome-associated protein 25 (SNAP-25) and results in bladder relaxation. A BTX-A intravesical injection has been established as an effective option for treating detrusor overactivity. STUDY DESIGN Sixty female Sprague Dawley rats were equally divided into control and experime...

PURPOSE To determine the effect of keratoconjunctivitis sicca, induced by botulinum toxin-B (BTX-B), on the inflammatory cytokine gene expression in the lacrimal gland (LG). And to determine the effect of various topical anti-inflammatory agents on the resulting cytokine levels. METHODS Forty-two mice (eight-week-old, female, CBA/J) were divided into six groups. Four groups were injected with...

The integration of gasification with syngas fermentation is still in an early stage development, where many questions exist concerning the quality required. challenge to define conditions that will provide a H2:CO:CO2 ratio suitable for fermentation, as well identify and remove compounds can inhibit performance microorganisms. right balance between line up minimal gas cleaning needs be assessed...

The state dependence of Na channel modification by batrachotoxin (BTX) was investigated in voltage-clamped and internally perfused squid giant axons before (control axons) and after the pharmacological removal of the fast inactivation by pronase, chloramine-T, or NBA (pretreated axons). In control axons, in the presence of 2-5 microM BTX, a repetitive depolarization to open the channels was req...

The authors evaluated the long-term efficacy and safety of botulinum toxin type A (BTX-A) in poststroke spasticity patients who completed a 12-week placebo-controlled study and received multiple open-label treatments with 200 to 240 U BTX-A for 42 weeks. Significant and sustained improvements were observed for Disability Assessment and Ashworth scores. Adverse events were generally mild. This e...

The clinical effect of botulinum toxin A (BTX-A) injection combined with spasmodic muscle therapeutic instrument with simple BTX-A injection was compared. Eighty patients with stroke were randomly divided into the treatment and control groups of 41 and 39 cases, respectively. The two groups of patients were given routine rehabilitation therapy. Ultrasound-guide positioning technology was used; ...

Batrachotoxin (BTX), a steroidal alkaloid, and pyrethroid insecticides bind to distinct but allosterically coupled receptor sites on voltage-gated sodium channels and cause persistent channel activation. BTX presumably binds in the inner pore, whereas pyrethroids are predicted to bind at the lipid-exposed cavity formed by the short intracellular linker-helix IIS4-S5 and transmembrane helices II...
