Researchers create artificial human ovary to yield infertility treatments for cancer patients

Researchers at Brown University and Women & Infants Hospital have invented the first artificial human ovary, an advance that provides a potentially powerful new means for conducting fertility research and could also yield infertility treatments for cancer patients. The team has already used the lab-grown organ to mature human eggs.

Success of assisted reproduction procedures linked to season

The success of an assisted reproduction procedure may depend on the season. This is the finding of new work presented at the World Congress of Fertility and Sterility, in Munich, Germany.

Two genes linked to ovarian clear cell carcinoma

Scientists at the Johns Hopkins Kimmel Cancer Center have identified two genes whose mutations appear to be linked to ovarian clear cell carcinoma, one of the most aggressive forms of ovarian cancer. Clear cell carcinoma is generally resistant to standard therapy.

Decreasing pituitary's sensitivity to insulin could be new target for infertility treatment

Obese women have a well-known risk for infertility, but a new Johns Hopkins Children's Center study has unraveled what investigators there believe is the mechanism that accounts for the risk.

Further evidence on adverse effects of smoking on fertility

Two new studies have shed more light on how smoking may damage fertility, and give further weight to advice that mothers and fathers-to-be should stop smoking before attempting to conceive. The research is published online in the reproductive medicine journal Human Reproduction today (Wednesday 8 September).

Genetic predisposition reduces breast, ovarian cancer risk with preventive surgeries: Study

A long-term study of women with a genetic predisposition for breast or ovarian cancer showed that those who elected major preventive surgeries had a significantly reduced risk of those cancers.

Preventive surgery protects against breast, ovarian cancer in women carrying BRCA1, BRCA2 gene mutations

Women who have gene mutations that put them at high risk of ovarian and breast cancer can significantly reduce the risk of developing or dying from these cancers by having their healthy ovaries or breasts removed, according to a new study reported in the Sept. 1 issue of the Journal of the American Medical Association.

Study: Preemptive surgery may help prevent cancer for some women

A study published in the Journal of the American Medical Association suggests that women with a gene mutation linked to breast and ovarian cancer face lower risks of developing such cancer after receiving mastectomies or having their ovaries removed, The Wall Street Journal reports.

Genetic testing, preventive surgeries can save women from ovarian and breast cancers

Women should be aware that options for these preventive surgeries have improved, the authors note. A laparoscopic salpingo-oophorectomy is a relatively low-risk procedure and can be done in an out-patient setting. And cosmetic options for women getting mastectomies have greatly improved.

Salpingo-oophorectomy and mastectomy decrease risk of cancer in women with BRCA1/2 gene mutations

Women at increased risk of breast and ovarian cancer because of inherited mutations of the BRCA1 or BRCA2 genes who had prophylactic mastectomy or salpingo-oophorectomy (removal of the fallopian tubes and ovaries) had an associated decreased risk of breast cancer and ovarian cancer, according to a study in the September 1 issue of JAMA.

Pathogens can delay entry into cells to ensure their survival, say researchers

Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure infection success. Pathogens can actually delay their entry into cells to ensure their survival.

Bisphenol A chemical may shorten reproductive lifespan in women: Research

A study posted today (Wednesday, August 25) at the online site of the journal Biology of Reproduction reports that exposure of pregnant female mice to the endocrine-disrupting chemical bisphenol A may produce adverse reproductive consequences on gene expression in fetal ovaries as early as 12 hours after the mother has first been exposed to the chemical.

Breast-specific gamma imaging increases radiation-induced cancer risk: Report

Some nuclear-based breast imaging exams may increase a woman's risk of developing radiation-induced cancer, according to a special report appearing online and in the October issue of Radiology. However, the radiation dose and risk from mammography are very low.

Arrayit selects PMA pathway for OvaDx Pre-Symptomatic Ovarian Cancer Screening Test

Arrayit Corporation, a leader in life sciences and healthcare technology, announces today that the company has chosen the Premarket Approval pathway for its OvaDx Pre-Symptomatic Ovarian Cancer Screening Test. While the standard for a PMA is higher than for a 510(k), the company believes that a PMA OvaDx submission can achieve a Class III PMA approval, the most stringent approval level granted by the FDA for in vitro diagnostic devices.

Cornell University experts comment on recall of 380 million eggs

Cornell University experts on farm animals and food safety comment on the recall of at least 380 million eggs in the past week due to concerns over salmonella contamination.

High exposure to estrogens may cause gall bladder cancer: Research

A very aggressive disease with a poor prognosis, gallbladder cancer may be connected to higher exposure to estrogens, according to a group of researchers at the University of Houston (UH). Dr. Jan--ke Gustafsson, Robert A. Welch Professor in UH's biology and biochemistry department, described his team's findings in a paper titled "Estrogen-dependent gallbladder carcinogenesis in LXRβ-/- female mice" appearing in a recent issue of the journal Proceedings of the National Academy of Sciences, one of the world's most-cited multidisciplinary scientific serials.

Oral contraceptives equally effective for obese women

The first study to compare the effectiveness of the birth control pill in women with marked weight differences has found that the pill works equally well in women with obesity and thinner women. This new finding by physician-scientists at NewYork-Presbyterian Hospital/Columbia University Medical Center refutes a long-held conviction among many doctors that the pill may not reliably prevent pregnancy in women who are overweight or obese.

Fertility preservation may be unsafe for leukemia patients: Study

Although the use of ovarian tissue cryopreservation and transplantation has lead to 13 live births in women with lymphoma or solid tumors, this method of fertility preservation may be unsafe for patients with leukemia, according to a recent study published online in Blood, the journal of the American Society of Hematology.

MabCure files provisional patent application for ovarian cancer diagnostic antibodies

Biotechnology company MabCure, Inc. today announced the company has filed a provisional patent application for its ovarian cancer diagnostic antibodies with the U.S. Patent and Trademark Office. The filing was based on positive results of a recent study that showed MabCure's tumor-specific monoclonal antibodies (MAbs) successfully identified ovarian cancer in blood (94 percent) and distinguished it from benign tumors of the ovaries or healthy blood obtained from men and women.

MabCure's MAbs 94% accurate in identifying ovarian cancer

Biotechnology company MabCure, Inc. today announced that a confirmatory study demonstrated the company's proprietary monoclonal antibodies (MAbs) successfully identified ovarian cancer in blood (94 percent accuracy) and with no false positives or cross-reactions with benign ovarian tumors or healthy blood. MabCure's serum diagnostic test is the first to recognize unique tumor markers or cancer fingerprints present only in ovarian cancer, the deadliest of all gynecological cancers.
