Hormonal imbalances occur when there is too much or too little of a hormone in the bloodstream. Because of their essential role in the body, even small hormonal imbalances can cause side effects throughout the body. Hormones are chemicals that are produced by glands in the endocrine system. Hormones travel through the bloodstream to the...

Tiny probe can see and take body temperatures
IMAGE: THE TINY IMAGING AND SENSING PROBE IS AS THIN AS A SINGLE STRAND OF HUMAN HAIR. University of Adelaide researchers have invented a world-first tiny fiber-optic probe that can simultaneously measure temperature and see deep inside the body. The probe may help researchers find better treatments to prevent drug-induced overheating of the brain, and potentially...

First seeds of kidney cancer sown in adolescence
Insights from this study present an opportunity to develop approaches for early detection and early intervention in kidney cancer The earliest critical genetic changes that can lead to kidney cancer have been mapped by scientists. The first key genetic change occurs in childhood or adolescence, and the resulting cells follow a consistent path to progress...

Statins associated with reduced morbidity and mortality in patients with primary sclerosing cholangitischolangi
12 April 2018, Paris, France: A large register-based study conducted in Sweden has found that statins are associated with a markedly reduced risk of all-cause mortality, liver transplantation, liver cancer, and variceal bleeding in patients with primary sclerosing cholangitis (PSC). The study, which reviewed the records of almost 3,000 patients diagnosed with PSC between 2005...

Weight loss is an important predictor of cancer
Unintended weight loss is the second highest risk factor for some forms of cancer, concludes the first robust research analysis to examine the association. A team led by the Universities of Oxford and Exeter conducted the first systematic review and meta-analysis to examine all available evidence on the association between weight loss and cancer in primary care. Their...
