Active clinical trials for "Atrophy"

The overall goal of PROBE is to evaluate the feasibility and potential utility of three markers (alpha-synuclein, transcriptomic profiles and olfactory function) to determine the risk or prognosis of PD.

In this project, we will establish the efficient and accurate gene dose determination system by combining the heterodulex analysis and gene dose analysis on DHPLC platform based on various quantitative and multiplex PCR strategies and applying on detecting the carriers- in- risk and patients with spinal muscular atrophy.This method is, therefore, based on the observation that the amount of PCR product generated from each site of amplification is proportional to the amount of starting template. Detection of PCR products is carried out on DHPLC, which provide the sensitivity required for the detection of the single-copy dosage changes.

Experienced endoscopists will perform endoscopy during the study period and the detection rate of gastric premalignant lesion, correlation between endoscopic and serologic diagnosis of premalignant lesions and inter-observer agreement rate will be analyzed before and after the education.

Given the aging population who will be affected by wet AMD and lack of effective GA treatment, it is crucial to assess the safety profile of repeated ranibizumab injections in AMD patients with GA, particularly the possible risk of GA development and enlargement. This potential adverse effect has significant implication in the discussions with patients regarding the risks and benefits of AMD treatment and injection frequency. While monthly injections provide slight improvement of visual acuity at 2 years (Martin et al., 2012), the risk of GA enlargement may offset this benefit in visual acuity. Previous studies assessed the association between intravitreal ranibizumab injections and de novo GA development in injection-naïve eyes (Martin et al, 2012, Querques et al., 2012., Grunwald et al., 2014), rather than GA enlargement in patients with preexisting GA. To the best of the investigators knowledge, there has been no prospective study assessing the association between intravitreal ranibizumab injections and rate of GA progression in patients with pre-existing GA. There is also no prospective study comparing the morphological features of GA between patients who are receiving intravitreal injections and those who are not, nor the concordance of GA enlargement rate between the 2 eyes among patients receiving and not receiving treatment.

The open, prospective, non-controlled observational study is designed to provide information on the short-, medium- and long-term clinical performance of the Astra Tech OsseospeedTM implant surface in combination with a special implant design. The study will provide information on implant survival and soft tissue and bone maintenance as clinical performance of the OsseoSpeedTM TX Profile Implant in the aesthetic zone or the posterior mandible with socket like atrophy.

Progressive Supranuclear Palsy (PSP), Cortico-Basal Degeneration (CBD) and Multiple System Atrophy (MSA) are degenerative brain conditions for which there are currently no curative treatments. To aid the development of new treatment trials, there is a pressing need to develop better methods for diagnosing these conditions early, and to track disease progression. The PROSPECT-M-UK study will collect standardised clinical data over time. Patients will also have the option to have a brain MRI scan, eye movement exam and donate blood, skin and spinal fluid samples, with the aim to identify "biomarkers" that can improve the accuracy of early diagnosis and track the natural time course of disease. Control participants and those not meeting criteria for Parkinson's disease or other defined conditions but are considered by the investigator group to be allied syndromes or at risk states (atypical parkinsonian syndromes), will also be examined. Patients can also participate via the CBD European registry or in a one-off study assessment through the cross-sectional study, which involves completing questionnaires and a blood sample donation.

Methodology :Phase III study, single centre, double blind, versus excipient, randomised, controlateral design. Selection of the patients :Number of subjects required 60 : 30 patients needing an oral corticotherapy 30 patients needing a topical corticotherapy

fixation of FGG with sutures alone is not sufficient,we use cyanoacrylate beside sutures for fixation

This study provides further theoretical guidance for clinical application of FCVB through observing and collecting various indicators before and after surgical treatment of the FCVB in the real world.

This study will examine the influence of n3 PUFA supplementation on the rate of muscle atrophy in older women undergoing 1 week of unilateral limb immobilization. Assessments in skeletal muscle strength and skeletal muscle volume will also me made before, after and in recovery from immobilization.
