Why Hormone Replacement Therapy May Be Safer Than You Think
The pendulum has swung from one extreme to the other when it comes to hormone replacement therapy (HRT) to treat symptoms of menopause. At first, the replacement hormones—mostly a combination of estrogen and progestin to replace what the body stops making after menopause—were seen as a panacea. Doctors thought they could not only relieve hot flashes and night sweats, but also prevent chronic aging diseases like heart problems and weakening bones. But studies then found that the supplement hormones could lead to a higher risk of breast cancer—and that they didn’t protect the heart after all. In the latest study on the subject, published in JAMA, researchers led by Dr. JoAnn Manson from the division of preventive medicine at Brigham and Women’s Hospital report on the longest follow-up of the original hormone therapy study, which used data from the Women’s Health Initiative. More than 27,000 women who were randomly assigned to receive either a placebo, a combination of hormones (estrogen plus progestin) or estrogen alone if they had had a hysterectomy. They were followed for 18 years and tracked for chronic diseases like cancer, as well as heart attack and deaths. The women took the hormone therapy for five to seven years. By the end of the 18-year study, the death rates from any cause among the women receiving some form of hormone therapy were similar to that of women who took the placebo.

Abstract Receptor tyrosine kinases (RTKs) such as the insulin-like growth factor type 1 receptor (IGF-1R) control important biological activities as well as being involved in pathological processes. Due to their supportive nature in many human cancers they have long been considered attractive therapeutic targets. However, lessons learnt from early targeting trials highlight that a simple "active versus inactive" state model with classical kinase-only signaling is overly simplistic and does not describe reality. A vast amount of evidence exists disproving this model and hence provides a rational explanati...

We identified the alpha1 and beta1 subunits of soluble guanylyl cyclase (GUCY1A1, GUCY1B1) as major ERG-regulated genes in prostate cancer cells. Soluble guanylyl cyclase (sGC) is the major mediator of nitric oxide signaling in cells that, upon nitric oxide binding, catalyzes the synthesis of cGMP and subsequently activates PK...
Consolidating all Medicare drug payments under Part D sounds easy, but some cancer patients fear they'll take a hit
In this study, a comprehensive dielectric spectroscopy study is conducted for the first time to characterize the ultra-wideband dielectric properties of freshly excised normal and malignant skin tissues obtained from skin cancer patients having undergone Mohs micrographic surgeries at Hackensack University Medical Center. Measurements are conducted using a precision slim-form open-ended coaxial probe in conjunction with a millimeter-wave vector network analyzer over the frequency range of 0.5–50 GHz. A one-pole Cole–Cole model is fitted to the complex permittivity dataset of each sample. Statistically considera...
Conclusion: The original model morphing algorithm is fast and robust with low computational cost. Significance: This low-cost model morphing algorithm may be highly beneficial for future patient-specific reduced-order modeling of the LV with potential application to other crucial organs.
Drinkers in particular need to be more aware of mounting evidence of links between alcohol and cancer, and make judgements accordingly
HIGH blood pressure happens when the force blood is pumped around your body and the resistance to blood flow is higher than recommended levels. It is important to lower your blood pressure if it is too high, as it increases your risk of developing heart disease, kidney disease and strokes among others. Drinking this £2 juice could lower your blood pressure.
