Normal bone marrow function depends on the coexistence of normal hematopoietic stem cells and a microenvironment mostly located in the medullary part of the bones. Stem cells cannot function properly in the absence of an adequate microenvironment. Whereas in malignant and non-malignant hematologic diseases caused by a deficiency or abnormal stem cells, stem cell transplantation is the treatment of choice that results in a cure, in diseases such as MDS, myelofibrosis, and other conditions associated with an abnormal microenvironment, pancytopenia may occur despite the presence of apparently normal hematopoietic cells with no recognizable cytogenetic abnormality. We, the investigators at Hadassah Medical Organization, proved in experimental studies that the entire osteohematopoietic complex consisting of trabecular bone, hematopoietic microenvironment (of stromal origin) and hematopoietic tissue has been successfully transferred directly into ablated bone marrow cavity in a one-step transplantation procedure. The goal of this study is to enhance hematopoiesis in patients with myelofibrosis syndrome by intraosseous inoculation of demineralized bone matrix (DBM) together with allogeneic bone marrow cells (BMC).
Irritable bowel syndrome is responsible for chronic abdominal pain, diarrhea and/or constipation. It is a very frequent problem. However, the exact cause of irritable bowel syndrome remains unknown. The purpose of this study is to look for a different cerebral response by magnetic resonance imaging after rectal stimulation in patients with irritable bowel syndrome compared to healthy subjects and to patients with digestive organic disease. Our hypothesis is that irritable bowel syndrome could be a problem of cerebral integration of visceral stimulation.
Anal incontinence and constipation are frequently observed in patients with neurological disease. The purpose of this study is to evaluate the neurological control of the anal sphincter in healthy subjects, patients with neurological disease by a new electrophysiological technique. This technique consists in recordings of anal sphincter responses after magnetic stimulations of the cortex and the sacral nerves.
The study objective is to develop data for the safety of pregnancies after thermal ablation of uterine fibroids by MR guided Focused Ultrasound using the Ex Ablate 2000 system.
The proposed study will test the safety and efficacy of sodium valproate in the induction of Epstein-Barr virus (EBV) lytic cycle antigen expression in tumor tissue of patients undergoing primary therapy for nasopharyngeal carcinoma. Up to 20 patients will be given valproic acid for 2 weeks. The primary surrogate endpoint for efficacy will be expression of EBV lytic antigens by immunohistochemistry in tumor tissue. Biopsies of primary tumor will be taken after 2 weeks with achievement of a therapeutic concentration of valproate. Expression of immunodominant EBV latency antigens in tumor tissue, EBV viral load by real time PCR, and valproate levels will be measured. Adverse events associated with valproate in NPC patients will be described.
A phase I/II study is conducted to determine the maximum-tolerated dose (MTD), dose-limiting toxicity (DLT), and efficacy of a combination chemotherapy using CPT-11 and Paclitaxel in pre-treated patients with metastatic gastric cancer. The usefulness of the this regimen is evaluated by response rate, median survival time, and progression free survival.
The objectives of this study are: 1. To evaluate the effect of clonidine, a sympathetic modulator, to reverse cardiac remodeling and to improve hemodynamics in diastolic heart failure (DHF). 2. To evaluate the effect of clonidine on neurohormones and quality of life in patients with DHF. The study is a double-blind, placebo-controlled study evaluating the effects of clonidine compared to placebo in patients with DHF. A total of 70 patients with DHF will be randomized in a 1:1 ratio to: 1. placebo (n=35) or to 2. clonidine (n=35) in a dose of 0.075 mg twice a day for the first 6 weeks followed by uptitration to 0.150 mg twice a day for 6 months. The primary outcome is the reversion of cardiac remodeling and hemodynamic parameters evaluated by magnetic resonance imaging (MRI) and echocardiography.
To evaluate the safety and tolerability of intravenous zoledronic acid in the treatment of patients with multiple myeloma stage III with bone lesions related to Cancer.
The purpose of this study was to determine the feasibility of an implanted electrical stimulation system incorporating BION microstimulators for long term use to prevent tissue breakdown in high risk patients.
