Introduction: Gasoline is a complex mixture of more than 500 various hydrocarbons. The elimination of lead from petrol has been associated with the production of significant amounts of hepatotoxic and nephrotoxic monocyclic aromatic hydrocarbons such as benzene, toluene and xylene (BTX). The main purpose of this study was to ascertain whether or not exposure to unleaded petrol, under normal wor...
Brevetoxin-1 (BTX-1), a marine toxin mostly produced by the dinoflagellatae Karenia brevis, has caused the death of marine organisms and has had numerous toxicological effects on human health. Hence, it is very necessary to develop a rapid, economical, and reliable immunoassay method for BTX-1 detection. In this study, two kinds of complete antigen were synthesized using the succinic anhydride ...
Botulinum toxin (BTX) is a neurotoxin, and its injection in masticatory muscles induces muscle weakness and paralysis. This paralytic effect of BTX induces growth retardation of the maxillofacial bones, changes in dental eruption and occlusion state, and facial asymmetry. Using masticatory muscle paralysis and its effect via BTX, BTX can be used for the correction of malocclusion after orthogna...
Background and objective : Gasoline is a complex mixture of more than 500 hydrocarbons. The elimination of lead from petrol has been associated with the addition of significant amounts of hematotoxic monocyclic aromatic hydrocarbons such as benzene, toluene and xylene (BTX). The main purpose of this study was to ascertain whether exposure to unleaded petrol, under normal working conditions, i...
Introduction: Synkinesis and facial asymmetry due to facial nerve palsy are distressing conditions that affect quality of life. Unfortunately, these sequelae of facial nerve palsy are unresolved. The aim of this study was to investigate the efficacy of a combination of biofeedback therapy and botulinum toxin A (BTX-A) injection for the management of synkinesis and asymmetry of facial muscles. ...
Botulinum toxin type A (BTX-A) has been used to treat several neurological conditions such as sialorrhea, hyperhydrosis, dystonia, hemifacial spasm, spasticity and pain. Although spasticity has been successfully treated with BTX-A, few are the authors studying the use of BTX-A to treat shoulder pain secondary to stroke. In order to study if BTX-A is effective to treat post-stroke shoulder pain,...
Mutational inactivation of p53 is a key player in the development of human cancer. Thus, retrieving the tumor suppressor activity of p53 gene is considered a novel strategy in cancer therapy. Current study aimed to investigate the anti-cancer potentials of botulinum toxin type-A (BTX-A) and captopril as a trial to shed light on effective anti-cancer therapy with lower side effects. Cytotoxic ef...
BACKGROUND The purpose of the meta-analysis was to evaluate the efficiency of therapeutic botulinum toxin type A (BTX-A) in the prevention of maxillofacial and neck scars. METHODS AND FINDINGS Information came from the following electronic databases: Medline, PubMed, Cochrane Library, and EMBASE (time was ended by August 31, 2015) to retrieve RCTs evaluating the effect of the BTX-A for hypert...
The crystal structure of a pentameric α7 ligand-binding domain chimaera with bound α-btx (α-bungarotoxin) showed that of the five conserved aromatic residues in α7, only Tyr¹⁸⁴ in loop C of the ligand-binding site was required for high-affinity binding. To determine whether the contribution of Tyr¹⁸⁴ depends on local residues, we generated mutations in an α7/5HT(3A) (5-hydroxytryptamine type 3A...
Ion permeation through voltage-gated sodium channels is modulated by various drugs and toxins. The atomistic mechanisms of action of many toxins are poorly understood. A steroidal alkaloid batrachotoxin (BTX) causes persistent channel activation by inhibiting inactivation and shifting the voltage dependence of activation to more negative potentials. Traditionally, BTX is considered to bind at t...
