With the current knowledge of aortic valve replacement modalities, no specific recommendations can be given and the decision for a particular prosthesis or procedure is rather arbitrarily. The investigators hypothesize that the autograft procedure according to Ross is superior in terms of hemodynamic (especially regression of left ventricular hypertrophy) and major adverse valve related events even in a long-term course

The main purpose of this study is to look for genetic and environmental risk factors of cervical artery dissections, a major cause of ischemic stroke in young adults, in a large multicenter case-control trial

The hypothesis is that there are unique sonographic characteristics of antibiotic-associated diarrhea. We will compare the ultrasound findings in patients who received antibiotics and developed diarrhea to toxin analysis for clostridium difficile in stool in order to find differences in the sonographic findings in the positive and negative cases.

The purpose of the study is to investigate the sensitivity and specificity of the Endotect compared with an ultrasound device in a flow-mediated vasodilatation (FMD) test.

The purpose of this study is to identify incidence of Chinese herb nephropathy in a medical center

Evaluation of Obstetrical Risk Factors for the development of Urinary and/or Fecal Incontinence according to a questionaire The questionaire will be filled by the study investigators after the women participating in the study sign their consent. The study is based solely on a questionaire and does not include any physical examination, blood exam or intervention. The study will be performed on the premises of Maaynei Hayeshua medical center. The inclusion criteria include women above the age of 18 who arrive to Maaynei Hayeshua Medical center for any reason. The data will be transferred to a computerized data base and analyzed statistically.

Objectives: Examine the acute utility of immediate maintained cannulations of a newly implanted prosthetic arteriovenous access. Background: Recurrent failure of central catheterization is not uncommon. An alternative access is necessary for acute hemodialysis after the exhaustion of central veins. Methods: We constructed the access by cannulating two dialysis needle-catheters and securing them on the skin after the implantation of the graft. The access was used immediately and maintained for one week and thereafter used as a long-term access.

Over the past several decades, considerable effort has been expended toward the successful cryopreservation of various human cells. While attempts at cryopreservation have been directed at different tissue types, one of the most vigorously pursued targets has been reproductive tissue. Historically, cryopreservation of human sperm has existed for several decades. The earliest reports of pregnancies (Trounson et al., 1983) and births (Zeilmaker et al., 1984) from the cryopreservation of human embryos occurred in the early 1980s. Presently, the freezing and storage of human embryos following in vitro fertilization (IVF) is standard practice at most fertility clinics. In 2003, the CDC Assisted Reproductive Technology success rates report stated that 4,246 live births occurred out of 17,517 non-donor frozen embryo cycles. . Because the human egg is a relatively voluminous cell with abundant cytoplasm, crystallization at the time of freezing may result in damage to the organelles. Secondly, a mature metaphase II oocyte contains a fragile spindle apparatus involved in cleavage. The purpose of this research study is to evaluate a method of freezing and thawing oocytes. This evaluation will be made by comparing the survival rates and rates of fertilization, cleavage and embryo quality of fresh oocytes and frozen-thawed oocytes which will be inseminated during the IVF (in vitro fertilization) treatment cycle. In addition, the same comparisons will be made between frozen oocytes from infertile women and those of egg donors. You are being asked to be in this study because you are currently undergoing in vitro fertilization.

The purpose of this study is to determine if patients are able to reliably screen themselves for nutrition risk.
