There is great interest worldwide in discovering and developing a permanent source of tissues which would be capable of generating any cell type and which would avoid the problem of transplant rejection. Stem cells are cells that can specialize into the many different cells found in the human body. The ethical objections concerning stem cells have focused primarily on their source. Human embry...

Angela is a 34-week neonatal patient born at 27 weeks gestation with a birth weight of 2 pounds. She has had a rough course in the Neonatal Intensive Care Unit. For the past two and a half weeks, Angela’s saturation rate has been in the low thirties, forties, and fifties. Whether she is on high frequency ventilation or regular ventilation, there seems to be no appreciable difference in saturati...

the clinical potentials of stem cells in cell-based therapies have raised great hopes in diabetes mellitus as well. however, there are complex ethical, legal, and socio-cultural issues surrounding the subject. in this paper, we intend to review in brief the main ethical issues for endocrinologists and other clinicians who are interested and work in the field of cell therapy and research.

Scatophagus argus argus (Green Scat) is a pretty aquarium fish. Its hard spines are venomous and can cause painful injury. In this study 60 specimens of Green Scat were collected periodically from coastal waters of Boushehr (south of Iran) from May 2011 to April 2012. Anatomical features of venomous spines were investigated. Scat venom was extracted from the spines in a new manner for keeping t...

To preserve professional autonomy, it is crucial for the physiotherapy profession to meet society’s expectations and demands of professional competence as well as ethical competence...

the ability to culture human stem cells long term, and possibly indefinitely, and to control how such cells specialise to form the different tissues of the body offers the possibility of major advances in healthcare. stem cells have been isolated and cultured, but a great deal of research is required to develop cell lines which can generate replacement cells and tissues to treat many diseases.s...

There has been considerable controversy surrounding the routine circumcision of male infants in the United States. This is of particular concern, since the medical establishments of all the other countries of the developed world have abandoned this procedure as having dubious benefits. This article examines the medical pros and cons of neonatal male circumcision in a historical perspective and ...
