This May Be The 'Most Contaminated Killer Whale' On The Planet

Researchers in Scotland believe they’ve found one of the most contaminated killer whales on the planet. They fear members of the orca’s pod may also have sky-high levels of chemicals in their bodies that render them infertile, scientists at Scotland’s Rural College said in a news release this week. New analysis of a deceased adult female killer whale, named Lulu by researchers, shows that the animal’s blubber contained some of the highest levels ever recorded of polychlorinated biphenyls, or PCBs, a toxic chemical once pervasive in electrical components. The researchers called Lulu the “Scottish killer whale most contaminated on the planet.” PCBs are banned in the U.K. and the U.S. due to toxicity. But because the chemical is resistant to extreme temperatures and pressures, it takes a long time to break down. PCBs still exist in the environment, and have been known to leach from landfills into groundwater, according to the U.S. Environmental Protection Agency. Andrew Brownlow, head of the Scottish Marine Animal Stranding Scheme, told BBC News that the level of PCBs found in Lulu’s blubber was shockingly high ― an estimated 20 times the rate considered safe for cetaceans. High levels of the chemical are linked to poor health, including impaired immune function, infertility and increased susceptibility to cancers. “That puts her as one of the most contaminated animals on the planet in terms of PCB burden, and does...

BulunSummaryDefective endometrial stromal fibroblasts (EMSFs) contribute to uterine factor infertility, endometriosis, and endometrial cancer. Induced pluripotent stem cells (iPSCs) derived from skin or bone marrow biopsies provide a patient-specific source that can be differentiated to various cells types. Replacement of abnormal EMSFs is a potential novel therapeutic approach for endometrial disease; however, the methodology or...

Authors: Cui W, Stern C, Hickey M, Goldblatt F, Anazodo A, Stevenson WS, Phillips KA Abstract Alkylating chemotherapy is often used to treat pre-menopausal women for various malignancies and autoimmune diseases. Chemotherapy-associated ovarian failure is a potential consequence of this treatment which can cause infertility, and increases the risk of other long term adverse health sequelae. Randomised trials, predominantly of women undergoing alkylating chemotherapy for breast cancer, have shown evidence for the efficacy of gonadotropin-releasing hormone agonists (GnRHa) in preventing chemotherapy-associated ovarian...

From a historical perspective, the main clinical and research focuses have been on the long-term health outcomes of infertile women, including the effects of ovarian stimulation on the risk of mortality and cancer. However, in recent years, it has become more evident that a man's reproductive and somatic health also are closely related.
