congenital muscular dystrophy (cmd)  is an umbrella term collecting a heterogeneous groups of genetic disorders , mostly with autosomal recessive mode of inheritance , and are characterized by muscle weakness since birth or in early infancy , with a dystrophic pattern on muscle biopsy . these children are usually hypotonic and may have joint contractures . the serum creatine kinase level can be...

Chimeric RNA/DNA oligonucleotides ("chimeraplasts") have been shown to induce single base alterations in genomic DNA both in vitro and in vivo. The mdx mouse strain has a point mutation in the dystrophin gene, the consequence of which is a muscular dystrophy resulting from deficiency of the dystrophin protein in skeletal muscle. To test the feasibility of chimeraplast-mediated gene therapy for ...

Objective(s): Pregabalin (PGB) is a new antiepileptic drug that has received FDA approval for patient who suffers from central neuropathic pain, partial seizures, generalized anxiety disorder, fibromyalgia and sleep disorders. This study was undertaken to evaluate the possible adverse effects of PGB on the muscular system of mice. Materials and Methods: To evaluate the effect of PGB on skeletal...

Numerous laboratory-based data have shown the ability of toluene (Tol) to exacerbate noise-induced hearing loss. However, the mechanism responsible for the synergistic effects of a coexposure to noise and Tol has not yet been completely elucidated. Recent investigations in rats have focused on quantifying the anticholinergic effects of certain aromatic solvents and have demonstrated that these ...

Duchenne muscular dystrophy (DMD) is an incurable genetic disease with early mortality. Multipotent mesenchymal stromal cells (MSCs) are of interest because of their ability to differentiate to form myogenic cells in situ. In the present study, methods were developed to expand cultures of MSCs and to promote the myogenic differentiation of these cells, which were then used in a new approach for...

muscular dystrophies are inherited disorders that cause progressive muscle weakness (myopathy) and atrophy (loss of muscle mass) due to defects in one or more genes required for normal muscle function. some of the genes responsible for these conditions have been identified .there are a number of different types of muscular dystrophy. the primary symptom for most types is muscle weakness, althou...

PURPOSE To develop a simple non-invasive method to assess the efficacy of a cell based therapy for treating stress urinary incontinence (SUI). MATERIALS AND METHODS In this study, skeletal myoblasts were used as candidate therapy to reverse SUI. The SUI model was created in rats using periurethral injection of botulinum-A toxin injection. Two weeks later, the rats were administered saline and...

the current study intends to analyze the effects of methionine on the ovulation of guinea pigs. 60 guinea pigs were given 4 different treatments in a completely randomize design. the treatments contained 0, 2, 4 and 6 percent of methionine per kg as fed. after two weeks as adaptation period, the four different treatments were given to the animals for two estrus cycle. after synchronization whic...

BACKGROUND Duchenne's muscular dystrophy is associated with severe, progressive muscle weakness and typically leads to death between the ages of 20 and 35 years. By inducing specific exon skipping during messenger RNA (mRNA) splicing, antisense compounds were recently shown to correct the open reading frame of the DMD gene and thus to restore dystrophin expression in vitro and in animal models ...

Sixty patients presenting for in-patient gynaecological laparoscopic surgery were randomly allocated to receive either diclofenac 75 mg (n = 20), ketorolac 30 mg (n = 20) or piroxicam 20 mg (n = 20) as an intra-muscular injection immediately after induction of anaesthesia. Postoperative visual analogue scores over the first 24 hours, using a 10 cm scale, ranged from 3.2-0.5 in the diclofenac gr...
