REVIEW
Didier Majou, Souad Christieans
For cured meat products, nitrite is recognized for its antimicrobial effects against pathogenic bacteria, even though the specific inhibitory mechanisms are not well known. Nitrite contributes to oxidative stress by being the precursor of peroxynitrite (ONOO- ), which is the major strong oxidant. Thus, bacterial stress (highly pH-very low partial pressure of oxygen-dependent) is enhanced by the nitrate-nitrite-peroxynitrite system which is also highly pH- and low partial pressure of oxygen-dependent. Nitrite is a hurdle technology which effectiveness depends on several other hurdle technologies including sodium chloride (accelerating the autoxidation of oxymyoglobin and promote peroxynitrite formation), ascorbate (increasing ONOO- synthesis), and Aw...

Botulinum neurotoxins (BoNT) are produced by several species of clostridium. There are seven immunologically unique BoNT serotypes (A⁻G). The Centers for Disease Control classifies BoNTs as 'Category A' select agents and are the most lethal protein toxins for humans. Recently, BoNT-like proteins have also been identified in several non-clostridia. BoNTs are di-chain proteins comprised of an N -terminal zinc metalloprotease Light Chain (LC) and a C-terminal Heavy Chain (HC) which includes the translocation and receptor binding domains...

Background: Cervical dystonia is a heterogeneous disorder with several possible presentations, for which first-line therapy is often botulinum toxin (BoNT). In routine clinical practice the success of each BoNT injection is dependent on several variables, including individual presentation and injection technique. Large multicenter, observational studies provide important information on individualized administration strategies that cannot be otherwise ascertained from controlled clinical trials...

Focal hyperhidrosis can have a considerable impact on social and occupational activities and be associated with significant impairment in quality of life. Primary (idiopathic) hyperhidrosis is neither caused by systemic disorders nor by external factors. It usually occurs in areas characterized by a high density of sweat glands such as the axillae and hands. The diagnosis of focal hyperhidrosis is based on history and clinical findings. Supplementary diagnostic tests include gravimetry (measurement of the amount of sweat) and the iodine starch test (which shows the area of sweating)...

Botulinum toxin (BT) is the treatment of choice for hemifacial spasm (HFS). When BT is injected into the affected side, patients may experience increased facial asymmetry. We wanted to evaluate in a prospective, randomised, placebo-controlled study whether bilateral BT injections may reduce this facial asymmetry. For this, we treated 19 HFS patients with unilateral and 24 with bilateral BT therapy using CBTX-A (Lanzhou Biological Products Institute, Lanzhou, China). BT doses on the affected side were standard doses, on the non-affected side they were one-third of those...

BACKGROUND: In this series of patients the cutaneous insertion and strength of voluntary contraction of the muscles in the upper third of the face were used as guidelines for botulinum toxin application named "BTA Codes." METHOD: Anatomical dissection of fresh cadavers identified the shape and cutaneous insertions of the muscles in the upper third of the face. Patient voluntary contraction of the muscles in the upper third of the face created different patterns of skin lines classified by the 4-grade Facial Wrinkle Scale...

Management of achalasia is potentially complex. Previous studies have identified equivalence between pneumatic dilatation and surgical cardiomyotomy in terms of clinical outcomes. However, previous research has not investigated whether a management strategies and outcomes are different in high-volume achalasia centers. This national population-based cohort study aimed to identify the treatment modalities utilized in centers, which regularly manage achalasia and those which manage it infrequently. This study also assessed rates of re-intervention and complications to establish if a volume-outcome relationship exists for the management of achalasia in England...

Introduction: Shoulder pain is one of the most common musculoskeletal diseases, and can be due to glenohumeral osteoarthritis, rotator cuff tear, impingement, tendinitis, adhesive capsulitis, and subacromial bursitis. Several therapies have been proposed, including steroids, nonsteroidal anti-inflammatory drugs, intra-articular injections, and physical therapies. Many published studies have reported on the employment of botulinum toxin type A (BoNT-A) to reduce pain in subjects with neurological and musculoskeletal diseases by inhibiting substance P release and other inflammatory factors...

Background: Botulinum neurotoxin type A (BoNT/A) is emerging as a treatment modality for Raynaud's phenomenon (RP). However, the mechanism of the role of BoNT/A in antagonizing the constriction of arteriola in RP remains unclear. Materials and methods: We tested the constriction of arteriole diameter and the distribution of adrenergic receptors on the rat cremaster modle. Moreover, we measured the secretion of norepinephrine (NE), protein level changes and related receptors on cultured rat superior cervical ganglia neurons(SCGNs), a model of sympathetic neuron...
