Filter by:The loss of muscle mass post-surgery confounds recovery efforts and leads to a delay in patient's ability to return to activities. Although the use of testosterone in aging and chronic muscle loss has been investigated, this study could prove short-term use of testosterone efficacious in preventing muscle atrophy due to surgery. We hypothesize that by bracketing an indexed knee surgery with testosterone undecanoate injections, post-surgical quadriceps muscle loss may be minimized. Determination of the effect of intra-muscular (IM) testosterone injections in preventing quadriceps muscle loss are measured by serial MRI and manual measurements of quadriceps cross-section.
Transcranial magnetic stimulation (TMS) is a procedure that has been shown to improve fatigue in chronic sufferers. It uses a plastic covered coil that sends a magnetic pulse through the skull into the brain and by targeting particular areas in the brain it can be used to help modulate the perception of fatigue. The study intends to use this technique to treat such a disabling symptom in patients who suffer from Multiple System Atrophy (MSA). Initially the aim is to study this technique in 22 MSA patients who are suffering from fatigue . These patients would require an resting-state funtional MRI before and after the stimulation. The stimulation would be performed ten sessions and the patients would be assessed by a clinician using well recognized clinical tools. It is anticipated that there will be a meaningful improvement in fatigue. It is also anticipated that TMS is a safety technique to use in MSA patients . Our findings will revealed that fatigue may be associated with an altered default mode network and sensorimotor network connectivity in MSA patients. We hypothesize that these divergent motor and cognitive networks connectivity changes and their adaptive or maladaptive functional outcome may play a prominent role in the pathophysiology of fatigue in MSA.
This is a randomized controlled trial to evaluate the use of LASER, Micro Ablative radiofrequency and topic strogen to treat symptoms of vulvovaginal atrophy of post menopause.
This study will enroll participants with idiopathic rapid eye movement (REM) sleep behavior disorder (RBD), for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.
The purpose of this study is to evaluate safety and efficacy of gene-activated matrix ("Nucleostim") for regeneration of bone tissue in maxillofacial area. Patients with congenital and acquired maxillofacial defects (sockets of extracted teeth, bone defects after injuries, surgeries, excision of benign neoplasms and pseudotumors, etc.) or alveolar bone atrophy will be included into the study.
Autologous MMSCs will be isolated from oral mucosa biopsy sample and expanded in vitro.Tissue engineered construction will be created using synthetic tricalcium phosphate and autologous MMSCs. Patients will undergo sinus lift procedure with implantation of created tissue-engineered construction. This is a single arm study with no control. All patients receive cell therapy.
The purpose of this study is to determine the anatomy of the retina and the optic nerve in patients with autosomal dominant optic atrophy (ADOA). Based on these findings the aim of the study is to determine why patients with the same type of genetic material, i.e. the same mutation, have such large variations of symptoms, spanning from unaffected subjects to blindness. The project requires examination of both healthy and affected family members.
