Filter by:The CO2RE laser system is a fractional CO2 laser that is FDA approved under a 510(k) K101321 for dermatologic procedures requiring ablation and coagulation of soft tissues, including the skin Eligible subjects will undergo 3 treatments in 4±1 weeks interval on the Vagina (External/Vulva and Internal/Vagina) with the CO2RE device according to study protocol. Subject will return for to 5 follow-up (FU) visits: 1 week ± 2 days post first treatment visit and 1, 3, 6 and 12 months after last (third) treatment (± 2 weeks). Methodology described in protocol to evaluate efficacy of treatments will be carried out at each visit at the clinic.
The Phase I/IIa clinical trial is designed to assess the feasibility of delivery and safety of Human Embryonic Stem Cell-Derived RPE Cells on a parylene membrane (CPCB-RPE1) in patients with advanced, dry age-related macular degeneration. Primary Objective: • To test the safety and tolerability of CPCB-RPE1 during and after subretinal implantation in patients with geographic atrophy with evidence of involvement of the central fovea. Secondary Objective: • To assess visual acuity, visual field, and retinal function after CPCB-RPE1 implantation. Implanted and fellow eyes will be compared post-implantation to assess the ability of the implant to prevent disease progression. Exploratory Objectives: • To assess the feasibility of measuring the change in area of geographic atrophy over time using spectral domain optical coherence tomography or fundus autofluorescence.
The primary objective of the study is to examine the efficacy of multiple doses of Nusinersen administered intrathecally in preventing or delaying the need for respiratory intervention or death in infants with genetically diagnosed and presymptomatic spinal muscular atrophy (SMA). Secondary objectives of this study are to examine the effects of Nusinersen in infants with genetically diagnosed and presymptomatic SMA.
The current project was designed to examine dynamic changes in muscle wasting during sepsis. Researchers will focus the mitochondrial dysfunction of muscle cells and investigate the role of HO-1 in it. Researchers interested in identifying factors involved in the pathology of muscle wasting during sepsis.
The purpose of this study is to determine whether mesenchymal stem cells (MSCs) can be safely delivered to the cerebrospinal fluid (CSF) of patients with multiple system atrophy (MSA). Funding Source - FDA OOPD.
Limb muscle dysfunction, characterized by atrophy and weakness, is amongst the most troublesome systemic consequences of chronic obstructive pulmonary disease (COPD) leading to poor functional status and premature mortality. One prevailing hypothesis stipulates that the deterioration in muscle structure and function during COPD results from a spillover of inflammatory mediators from the lungs to the systemic circulation and then to the muscles.

Atrogin-1 and muscle RING finger-1 are skeletal muscle specific genes, with ubiquitin ligase activities, that are upregulated during muscle atrophy in mice. The Akt/GSK3 and Akt/mTOR pathways are involved in muscle hypertrophy in mice. Recent studies by the investigators team and others have demonstrated the implication of these signalling pathways in the control of muscle mass in humans. However no study has yet investigated the involvement of these systems in the early stages of spinal cord injury induced human skeletal muscle atrophy. The investigators propose to investigate the level of expression of the different components of the ubiquitin-proteasome system together with the level of expression and activity of the Akt/mTOR and Akt/GSK3 signalling pathways after SCI in humans during the first months following the injury. A second aim of this project is to assess if a novel apparatus of electrical stimulation which generate movements by closed-loop electrical muscle stimulation may improve strength and muscle mass in these patients. The patients will be recruited jointly at the Clinique Romande de Réadaptation (CRR) in Sion and the Swiss paraplegic centre in Nottwil. They will be randomly divided into two groups, a first group of patients will undergo a conventional treatment of rehabilitation while a second set of patients will be treated using a brand new system of electro-stimulation called MotionMaker TM. Biopsies will be obtained in the first weeks after admission; two other biopsies will be taken respectively 3 and 6 months post-lesion. Our results will provide an increased understanding of the molecular mechanisms contributing to skeletal muscle atrophy during the early stages following SCI and a characterization of the impact of endurance training in the no more voluntary innervated muscle. Moreover this study will also investigate the potential improvement in the rehabilitation process by using a new system of electro-stimulation.
Stroke, a leading cause of disability in the aging population, increases the risk for diabetes, subsequent stroke recurrence, and cardiovascular disease complications. The downsizing of private and federal health care resources, along with the anticipated increase in stroke rates as our population ages, mandate that alternative strategies be developed to reduce the public health burden of stroke. This pilot study may facilitate our knowledge of the timing of paretic leg muscle atrophy, fiber type shift, and the progression of worsening of glucose tolerance after stroke. Knowledge of the skeletal muscle changes occurring in the sub-acute stroke period is essential to create new guidelines incorporating exercise rehabilitation, much like cardiac rehabilitation, in order to facilitate and improve the health care of veteran stroke survivors.
The proposed feasibility study is necessary to test if children and young adults will participate in and adhere to a 12-week, home-based, supervised progressive strength training exercise program and to obtain preliminary data that will subsequently allow us to determine the safety and impact of strength training in spinal muscular atrophy. Our pilot study will address 3 aims: (1) Ascertain the feasibility of, and potential barriers to, participation in and adherence to a 12-week home-based, supervised, progressive strength training exercise program in children and young adults aged 5-21 years with SMA types II and III; (2) Determine the safety and tolerability of progressive strength training in a pilot study sample of children and young adults with SMA types II and III; and (3) Determine candidate outcome measures.
