Hysterectomies Could Be Source of Stem Cells

Researchers eye tissues that are normally discarded after surgery.



Fallopian tubes removed from fertile women of child-bearing age during hysterectomies or other procedures might prove to be a new source of highly sought-after stem cells.

Researchers from the University of Sao Paulo in Brazil found that human fallopian tubes are rich in mesenchymal stem cells. The team isolated and grew these cells in a laboratory and differentiated them into muscle, fat, cartilage and bone cell lines without producing problems in the cell chromosomes, according to a report in the Journal of Translational Medicine.

"In addition to providing an additional potential source for regenerative medicine, these findings might contribute to reproductive science as a whole," study leader Tatiana Jazedje, of the university's Human Genome Research Center, said in a news release from the journal's publisher.

Past studies have also shown success with isolating and differentiating mesenchymal stem cells harvested from umbilical cords, dental pulp and body fat.

Together, these findings are of great interest, the researchers said. "Moreover, the use of human tissue fragments that are usually discarded in surgical procedures does not pose ethical problems," Jazedje said.

Reasons for female hair loss

The causes of female hair loss include physical, emotional, and hormonal reasons, as well as taking medications that can cause hair loss. Hormones play a major role in female hair loss. Many women lose their hair after pregnancy. Because of low levels of estrogen during pregnancy, and loss of natural hair which is supposed to not occur during the months of pregnancy. About three or four months after giving birth, and once that is stabilizing the hormones to normal, and the hair that was supposed to be lost during the pregnancy leave at a time. This hair loss is a temporary situation, and hair growth will resume regular sessions promptly. Any modifications to the cycle of birth control are also known to cause hair loss in some cases. Start or stop the pill and hormones for reasons other than stable, and sometimes lead to hair loss. Hormone replacement therapy can have the same results. The presence of DHT is also the initiator of hair loss. DHT is a hormone that weakens hair follicles,

Torn Surgical Gloves Put Patients at Risk for Infection

Giving antibiotics before operation might improve safety, study finds. Holes in surgical gloves increase the risk of surgical site infection among patients who aren't given antibiotics before their surgery, Swiss researchers say. In procedures lasting more than two hours, the rate of glove perforations ranges from 8 percent to 50 percent, according to a study published in the June issue of the Archives of Surgery. Sterile gloves worn by surgical staff can be perforated by needles, bone fragments and sharp surgical instruments, and the resulting holes enable skin-borne pathogens to travel from the hands of surgical staff into patients. In the study, Dr. Heidi Misteli and colleagues analyzed 4,417 surgical procedures performed at University Hospital Basel between 2000 and 2001, and found that sterile glove perforations occurred in 677 of the surgeries. Antibiotic therapy given before surgery to prevent infection was used in 3,233 of the surgeries, including 605 of the surgeries invol
