Breast cancer is a type of cancer that begins in the cells of the breast. It can occur in both men and women but is more common in women. Breast cancer can develop in different parts of the breast, including the tubes that carry milk to the nipple or the lobules that produce milk. The exact cause of breast cancer is not completely understood, but factors such as genetics, hormone situations, ...
Sleep is an important factor to help maintain health and well-being. It’s recommended that an adult should get at least 7 hours of sleep a night. Getting a good night’s sleep has many benefits such as better memory, reduced stress levels and lowers the risk of heart disease. On the flip side, not getting enough sleep regularly can have serious repercussions such as a weaker immune ...
Rani Therapeutics Holdings (NSDQ:RANI), developer of a robotic drug-delivery pill system, generated $73.3 million in its underwritten initial public offering (IPO) of Class A common stock. The San Jose, Calif.–based company’s IPO of 6.7 million shares priced at $11 a share, generating gross proceeds of $73.3 million. The company initially targeted an IPO worth approximately $100 ...
The goal of the present study was to evaluate the reproductive function of fathead minnows (Pimephales promelas) exposed to brominated diphenyl ether 47 (BDE‐47) at doses lower than used in previous studies. This was accomplished by evaluating the impacts of BDE‐47 exposures across multiple levels of biological organization. Breeding pairs were exposed to BDE‐47 via diet for 21 days during ...
Amid concerns about the toxicological effects and environmental prevalence of bisphenol A (BPA), efforts to find suitable, safer replacement alternatives are essential. Bisphenol S (BPS) is one potential chemical substitute for BPA; however, few studies are available confirming it has a more desirable ecotoxicological profile. In the present study, BPS was injected into the air cell of ...
Abstract: What's Safe in Your Medicine Cabinet: Dietary Supplements in the U.S. From regulating hormone levels to supplementing nutritional deficiencies in children, dietary supplements have a broad spectrum of needs to cater to. Popping a vitamin pill or biting down on an energy bar is not as simple as it once was though. The plethora of products available to supplement your diet are so ...
As knowledge of contaminants capable of adversely modulating endocrine functions increases, attention is focused on the effects of synthetic progestins as environmental endocrine disrupters. In the present study, effects of exposure to a synthetic progestin (norethindrone, 168 ± 7.5 ng/L) and endogenous progestogen (progesterone, 34 ± 4.1 ng/L) on steroidogenesis in adult female fathead minnows ...
Pentachlorophenol (PCP) is frequently detected in the aquatic environment and has been implicated as an endocrine disruptor in fish. In the present study, 4‐month‐old zebrafish (Danio rerio) were exposed to 1 of 4 concentrations of PCP (0.1, 1, 9, and 27 µg/L) for 70 d. The effects of PCP exposure on plasma thyroid hormone levels, and the expression levels of selected genes, were measured in ...
Great concern has been raised over the potential impact of environmental contaminants on fish populations that inhabit in the Three Gorge Reservoir (TGR). In the present study, we investigated the endocrine disrupting effects of di‐(2‐ethylhexyl)‐phthalate (DEHP), on the Chinese rare minnow (Gobiocypris rarus), an endemic fish distributing upstream waters in the Yangtze River. Adult rare ...
Perfluorooctane sulfonate (PFOS) is a widespread and persistent chemical in the environment. We investigated the endocrine‐disrupting effects of PFOS using a combination of in vitro and in vivo assays. Reporter gene assays were used to detect receptor‐mediated (anti‐)estrogenic, (anti‐)androgenic, and (anti‐)thyroid hormone activities. The effect of PFOS on steroidogenesis was assessed both at ...
