Hyperthermic intraperitoneal chemotherapy for treating ovarian cancer.

Hyperthermic intraperitoneal chemotherapy (HIPEC) has been used for decades as a treatment for disseminated abdominal malignancies, including pseudomyxoma peritonei and peritoneal mesothelioma. HIPEC had been used to treat recurrent ovarian cancer only when curative options were lacking, but new data indicate that it may be suitable as a primary treatment for patients with late-stage epithelial ovarian cancer, increasing the recurrence-free time interval and improving quality of life. However, treatment can be challenging because of patient trauma from surgery, combined with the toxicity and high temperature of the chemotherapeutic agents.

Function and viability of human islets encapsulated in alginate sheets: in vitro and in vivo culture.

Islet encapsulation offers an immune system barrier for islet transplantation, and encapsulation within an alginate sheetlike structure offers the ability to be retrievable after transplanted. This study aims to show that human islets encapsulated into islet sheets remain functional and viable after 8 weeks in culture or when transplanted into the subcutaneous space of rats. Human islets were isolated from cadaveric organs.

Influence of intermittent pneumatic compression devices on non-invasive blood pressure measurement of the ankle.

Background: It is rapidly becoming the standard of care to employ the perioperative use of intermittent pneumatic compression (IPC) devices on the lower leg to prevent the development of deep venous thrombosis. There are instances when the anesthesiologist must apply a blood pressure cuff to the ankle in order to obtain a blood pressure reading. The purpose of this study is to determine the influence of IPC devices on non-invasive blood pressure measurements of the ankle.

Preclinical development of the Islet Sheet.

The Islet Sheet is a thin planar bioartificial endocrine pancreas fabricated by gelling highly purified alginate and islets of Langerhans. Acellular alginate layers form a uniform immunoprotective barrier to host rejection of the encapsulated cells, with the tissue nourished by passive diffusion from adjacent host tissue. The overall thickness of the Islet Sheet, 250 microm, is chosen to maximize nutrient diffusion.

Extracorporeal whole body hyperthermia treatment of HIV patients, a feasibility study.

The literature supports that the retrovirus, Human Immunodeficiency Virus (HIV), which is thought to cause Acquired Immunodeficiency Syndrome (AIDS), is heat sensitive at temperatures which can be achieved in man. Invasive or non-invasive induction of whole body hyperthermia (WBH) has been used to treat an array of illnesses, primarily in the field of oncology, until recently. Non-invasive methods have proven to be less toxic than invasive means.
