Approximately 100,000 individuals in the United States currently await kidney transplantation, and 400,000 individuals live with end-stage kidney disease requiring hemodialysis. The creation of a transplantable graft to permanently replace kidney function would address donor organ shortage and the morbidity associated with immunosuppression. Such a(More)
End-organ failure is one of the major healthcare challenges in the Western world. Yet, donor organ shortage and the need for immunosuppression limit the impact of transplantation. The regeneration of whole organs could theoretically overcome these hurdles. Early milestones have been met by combining stem and progenitor cells with increasingly complex(More)
Dear Editor: Stapler hemorrhoidopexy (SH) is a commonly performed procedure that is associated with less pain and early recovery as compared to open hemorrhoidectomy. In SH, a column of rectal mucosa is excised and stapled at the same time with the help of a disposable stapler. There have been reports of retained staples causing symptoms after a variable(More)
End-stage lung disease is a major health care challenge. Lung transplantation remains the definitive treatment, yet rejection and donor organ shortage limit its broader clinical impact. Engineering bioartificial lung grafts from patient-derived cells could theoretically lead to alternative treatment strategies. Although many challenges on the way to(More)
We describe a technique for the management of large benign ovarian cysts by single incision laparoscopic surgery (SILS) through the umbilicus. The paucity of intra-abdominal working space in large ovarian cysts poses a technical challenge. Moreover, difficult convergence of operating instruments and competition for operating space outside the abdomen during(More)
Associative learning is key to how bees recognize and return to rewarding floral resources. It thus plays a major role in pollinator floral constancy and plant gene flow. Honeybees are the primary model for pollinator associative learning, but bumblebees play an important ecological role in a wider range of habitats, and their associative learning abilities(More)
BACKGROUND More than 11 million Americans live with chronic lung disease; in search for an alternative to donor organs, we attempted to regenerate lungs based on perfusion decellularized lung scaffolds that can be transplanted similar to a donor organ. METHODS Cadaveric rat lungs were decellularized by detergent perfusion. Resulting scaffolds were mounted(More)
In this paper, we show the blood-cell image classification system to be able to analyze and distinguish blood cells in the peripheral blood image. To distinguish their abnormalities, we segment red and white-blood cell in an image acquired from microscope with CCD camera and then, apply the various feature extraction algorithms to classify them. In addition(More)
The presence of coronary artery calcium is closely associated with the presence of atherosclerotic lesions in the coronary vasculature. Detection of coronary calcium by imaging techniques has evolved over the last few decades and has become especially more sophisticated with advanced imaging technology. Whereas the status of coronary artery calcium as a(More)
Tumor suppressor p53 is required for the neuronal apoptosis in response to DNA double-stranded break (DSB) damage. Posttranslational modifications such as phosphorylation play important roles in activating p53-dependent apoptosis after DNA damage. In support of this notion, our recent studies indicate that Ser18 and Ser23 phosphorylation together plays(More)
