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...

This study was aimed to investigate the anti-oxidative and the ameliorative effects of Antrodia cinnamomea ethanol extract (ACEE) on reproduction dysfunction in male diabetic rats. The diabetic condition was induced by administrating the combination of streptozotocin (STZ) (65 mg/kg) and nicotinamide (NA) (230 mg/kg). Three different doses of ACEE were tested (385, 770, 1540 mg/kg) for 5 weeks. The results indicated that the ACEE improved STZ-NA induced hyperglycemia, oxidative stress, and insulin resistance. In addition to this, ACEE reduced the degree of lipid peroxidation, recovered the abnormal str...

AbstractBackgroundWhile the spermatotoxic properties of cancer treatments such as chemotherapy and radiation therapy are widely recognized, the effect of malignancy itself on male fertility is not clearly understood.ObjectivesTo determine whether malignancy is associated with diminished semen quality prior to spermatotoxic treatment among sperm bankers.Materials and MethodsRetrospective database review of de ‐identified records was obtained for all episodes of sperm banking performed at a cryobank from January 2004 to May 2017 for one of the following reasons: ‘future use’ (e.g., military deployment and gende...

(Natural News) You might remember that in 2012, The U.S. Food and Drug Administration (FDA) banned the sale of baby products that contained bisphenol-A (BPA). The ruling was made in response to the countless amount of data that showed that BPA was an endocrine disruptor associated with an increased risk of cancer, infertility, and other...

Abstract The combination of doxorubicin and cyclophosphamide commonly used to treat breast cancer can cause premature ovarian failure and infertility. α-Tocopherol is a potent antioxidant whereas γ-tocopherol causes apoptosis in a variety of cancer models in vitro including breast cancer. We hypothesised that the combination of doxorubicin (Dox) and 4-hydroperoxycyclophosphamide (4-Cyc) would be more cytotoxic in vitro than each agent alone, and that α-tocopherol would reduce and γ-tocopherol would augment the cytotoxicity of the combined chemotherapeutics. Human MCF-7 breast cancer and KGN...

Abstract The ovarian steroid hormones, estrogen (E2) and progesterone (P4), are essential regulators of uterine biology. The imbalance of these ovarian steroid hormones leads to uterine diseases such as endometrial cancer, endometriosis, and infertility. Mitogen-inducible gene 6 (MIG-6) is an adaptor protein. MIG-6 mediates P4 signaling and acts as a tumor suppressor during endometrial tumorigenesis in both humans and mice. In previous studies, we developed the conditional knockout of Mig-6 in all uterine compartments (Pgrcre/+Mig-6f/f; Mig-6KO) and endometrial epithelial cell-specific Mig-6 knockout (Sprr2fcre/+M...

Over 10% of new cancer diagnoses occur in reproductive aged women, impacting 87 per 100,000 women each year [1]. Improvement in the management and treatment of these patients is leading to improved survival [2] and greater interest in survivorship outcomes. There is a growing movement to preserve the fullness of cancer patients ’ future. Satisfactory quality-of-life in cancer survivors may include the ability to conceive children and the infertility associated with cancer treatment can contribute to profound distress and depression in survivors [3].
