Prognostic Value of Stem Cell Related Markers

Start date: February 2011
Phase: N/A
Study type: Observational

The goal of the investigators study is to identify a prognostic marker that will evaluate the probability of recurrence in patients with stage 0-II breast cancer following surgery to remove the tumor.

NCT ID: NCT01223638 Withdrawn - Hearing Loss Clinical Trials

The Prevalence of Hearing Loss Among Children With Congenital Hypothyroidism

Start date: September 2010
Phase: N/A
Study type: Observational

Congenital hypothyroidism (CH) occurs in 1:4000 live births. Neurological disturbances like speech delay, motor delay and lower IQ were reported in children with CH. Evidence from animal experiments indicate that CH is associated with high frequency of deafness. Morphological changes of the external and internal cholera hairs were reported in mutagenic mice with CH. Anatomical changes of the internal ear and low hearing threshold were reported in mice bearing Dual oxidase 2 (Duox2) gene mutations, which is responsible of oxidation of iodide. Knockout of Pax8 gene in mice resulted in both agenesis of thyroid gland and deafness. Early L-thyroxin therapy prevented the development of deafness in those mice. The expression of thyroid receptor α (TRα) in the external and internal cholera hairs in mice indicates that the thyroid hormones have an important role in the development of the internal ear. The etiology of deafness in human is both genetic and environmental. The prevalence of deafness in live births is 1:1000 and among them 60% is genetic. Connexin 26 gene mutations are the most common cause of inherited deafness and account for about 40% of the genetic cases. In two conditions in human the coexistence of hypothyroidism and deafness were reported; Pendred syndrome and thyroid hormone resistance syndrome. The prevalence of hearing loss in human with CH was explored in only few studies and the results are contrary. The aim of the current study is to study the prevalence of hearing loss among children with CH and to compare the clinical, biochemical and genetic characteristics between subjects with hearing loss to those without hearing loss.

NCT ID: NCT01204827 Withdrawn - Chronic Hepatitis B Clinical Trials

Follow Up of Patients Chronic Hepatitis B (CHB) Treated With Sebivo Using the 13C Methacetin Breath Test

Start date: n/a
Phase: Phase 2/Phase 3
Study type: Interventional

Patients with HBeAg negative chronic HBV and evidence of hepatic disease (elevated liver enzymes or evidence of cirrhosis) who have significant viremia are treated with anti HBV therapy. Currently the key goals of anti HBV therapy are profound and prolonged viral suppression and treatment efficacy is assessed by monitoring viral load and liver enzymes. However these do not always reflect the degree of liver impairment or the degree of improvement in response to therapy. Sebivo has been accepted in Israel as a first line therapy for HBeAg negative and HBeAg positive chronic HBV with evidence of liver damage. Viral load should decrease by 1 log every 3 months, otherwise patients should be offered add-on or alternative therapy. As the majority of patients in Israel are HBeAg negative chronic HBV and in order to have homogenous population we will select for our study only patients with HBeAg negative chronic HBV. The 13C Methacetin breath test, assess liver function and specifically the function of the microsomal CYP4501A2. It has been shown to correlate with the degree of liver impairment and with clinical outcomes in both acute and chronic liver disease. The aim of this study is to determine the utility of the 13C Methacetin Breath Test to follow up patients with HBeAg negative chronic HBV receiving anti viral therapy.

NCT ID: NCT01178606 Withdrawn - Healthy Clinical Trials

Measurement of Echogenic Area in the Border of the Fetal Ventricles

Start date: September 2010
Phase: N/A
Study type: Observational

Sonographic coronal section in the lateral fetal ventricles shows echogenic area in the ventricles borders creating an "halo" around the ventricles. Histologically this area correlates to the Stratified transitional field. In this study we would like to measure this area for the purpose of creating a nomogram.

NCT ID: NCT01177644 Withdrawn - Clinical trials for Age-Related Macular Degeneration

Safety and Preliminary Efficacy Study of PDS-1.0 in Patients With Neovascular AMD

Start date: January 2011
Phase: Phase 1
Study type: Interventional

This study will evaluate the safety and preliminary effectiveness of PDS 1.0 in patients with neovascular AMD.

NCT ID: NCT01174537 Withdrawn - Glioblastoma Clinical Trials

New Castle Disease Virus (NDV) in Glioblastoma Multiforme (GBM), Sarcoma and Neuroblastoma

Start date: July 2011
Phase: Phase 1/Phase 2
Study type: Interventional

Patients with specific metastatic cancers who failed prior therapeutic regimes will be treated with NDV for at least a year or until disease progression. The study will measure progression-free disease and posits that it will be extended.

NCT ID: NCT01153945 Withdrawn - Thyroid Cancer Clinical Trials

Association Between Cancer Cells and Normal Versus (Vs.) Low Levels of Thyroid Hormones in the Serum

Start date: February 2011
Phase: N/A
Study type: Observational

Much experimental data has suggested that thyroid hormones (T3 and T4) may modulate neoplastic cells and that T3/T4 deprivation may remove this stimulus. It is now well established that T3/T4 affects cell division/angiogenesis through binding to integrin avb3, commonly over-expressed on many cancer cells. In the experimental settings, mimicking hypothyroidism in the cells is a difficult task. Currently, the use of charcoal stripped serum is used. Using this method, the serum is stripped not only from T3 and T4, as intended, but also from central and important cytokines and growth factor. This leads to a reduced rate of cancer cell proliferation and thus, does not reflect the natural environment in which cancer cells residue under hypothyroid conditions. The investigators aim to characterize and establish the effects of serum from hypothyroid patients on the proliferation/viability of a variety of cancer cell models.

NCT ID: NCT01152658 Withdrawn - Clinical trials for Partial Supraspinatus Tear

PrgfRC001IL
Start date: April 2010
Phase: Phase 1
Study type: Interventional

The objective of this clinical trial is to evaluate the impact and symptomatic efficacy of platelets rich plasma (PRP \ PRGF) in the treatment of partial tears of supraspinatus tendon of rotator cuff. Speed of tendon healing of partial thickness tear of the supraspinatus tendon influenced by local injection of platelets rich plasma
