Might there be a unifying element to our biology and the health and longevity effects induced by our behaviors and environment ? Not a theory of everything but a way of tying together the complex parts of human lives and wellbeing that not only is heuristic but clearly points the way to having a longer and healthier life? That is what you will be treated to in The Telomere Effect: A Revolutionary Approach to Living Younger, Healthier, Longer. This is no snake oil.

Bodywide immune response important for fighting cancer, Stanford researchers say
Fighting off cancer requires the concerted efforts of immune molecules throughout the body, rather than just in the tumor itself, according to a new study of laboratory mice by researchers at the Stanford University School of Medicine. The finding helps settle an ongoing dispute among clinicians as to whether systemic, or whole-body responses, are as important as a robust response by immune cells in the tumor itself.

Study provides insights into CPEB4 gene and fatty liver disease
This condition generally leads to chronic inflammation , which can trigger fibrosis, cirrhosis and ultimately liver cancer. This study on the basic biology of the liver paves the way to examine therapeutic strategies to fight and prevent fatty liver disease .
Asthma Diagnosis Later Reversed in About 1 in 3 Adults, Study Finds
Although asthma is considered a chronic disease, doctors have been puzzled by its often changing nature that can makes prescribing medicine, or stopping them, tricky. A study published Tuesday in the Journal of the American Medical Association found that about one-third of adults tested for the study, who had been diagnosed with asthma in the previous five years, showed no evidence of the condition during later follow-up examinations and testing.
Every meal triggers inflammation
When we eat, we do not just take in nutrients – we also consume a significant quantity of bacteria. The body is faced with the challenge of simultaneously distributing the ingested glucose and fighting these bacteria.

IsoPlexis Awarded Nih Sbir Grant to Develop Cellular Analysis Platform…
Alzheimer’s and other neurodegenerative diseases have tremendous unmet therapeutic and diagnostic need, and we are excited to be in a position to address these challenges with our platform. IsoPlexis Corporation , a venture-capital funded life sciences company developing an innovative cellular response analysis platform to measure the proteomic function of individual cells in patients, today announced it was recently awarded a competitive Phase I Small Business Innovation Research grant from the National Institute on Aging of the National Institutes of Health to develop a system to analyze trafficking leukocytes’ highly multiplexed proteomic responses in patients with Alzheimer’s disease.
Amyloid and Tau have Synergistic Effects on the Progression of Alzheimer’s Disease
Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging.
What does it take for an AIDS virus to infect a person?
Upon sexual exposure, the AIDS virus must overcome some mighty barriers to find the right target cell and establish a new infection. It must traverse the genital mucosa and squeeze through tightly packed epithelial cells meant to keep invaders out.
Prostate cancer genetics could aid cure: study
Canadian researchers have identified a genetic fingerprint that explains why up to almost a third of men with potentially curable localized prostate cancer develop aggressive disease that spreads following initial treatment. Co-principal investigator Dr. Robert Bristow of Toronto’s Princess Margaret Cancer Centre says the discovery could help doctors personalize more effective, targeted therapies from the moment a man is diagnosed with prostate cancer.

A novel NHS mutation causes Nance-Horan Syndrome in a Chinese family
Nance-Horan Syndrome is a rare X-linked developmental disorder characterized by bilateral congenital cataracts, with occasional dental anomalies, characteristic dysmorphic features, brachymetacarpia and mental retardation. Carrier females exhibit similar manifestations that are less severe than in affected males.

CDH3 on 16q22.1 is responsible for two rare autosomal recessive disorders with hypotrichosis and progressive macular dystrophy: Hypotrichosis with Juvenile Macular Dystrophy and Ectodermal Dysplasia, Ectrodactyly and Macular Dystrophy. We present a new case of Hypotrichosis with Juvenile Macular Dystrophy.
‘We could make that!’ – Chance meeting leads to creation of antibiotic spider silk
An interdisciplinary team of scientists at The University of Nottingham has developed a technique to produce chemically functionalised spider silk that can be tailored to applications used in drug delivery, regenerative medicine and wound healing. A chance meeting between a spider expert and a chemist has led to the development of antibiotic synthetic spider silk.

Why More Women Get These Diseases Than Men
Nearly 80% of people who suffer from autoimmune diseases are women, and why that’s the case has long been a medical mystery. But new research suggests the answer may have to do with differences between men’s and women’s genes – a discovery that could pave the way for better diagnostic methods and treatments in the future.
Stem cells give scientists a new window into the biology of a rare disease
Today, Stanford pediatric cardiologist Marlene Rabinovitch , MD, and her team published new research that advances their quest to understand a serious – and very puzzling – lung disease. They’re studying pulmonary arterial hypertension , which frequently leads to heart failure.

Combination therapy holds great promise to clear precancerous skin lesions
A combination of two FDA-approved drugs – a topical chemotherapy and an immune-system-activating compound – was able to rapidly clear actinic keratosis lesions from patients participating in a clinical trial. Standard treatment for this common skin condition, which can lead to the development of squamous cell carcinoma, takes up to a month and can elicit several unpleasant side effects.
This drugmaker is taking an unprecedented approach to getting its cancer treatment approved
As researchers look for new approaches for tough-to-treat cancer, many are looking into genetics – more specifically, they’re looking at the type of genetic mutations found in cancerous tumors. One company in particular, called Loxo Oncology is building drugs that act on those mutations, so that the type of cancer someone has wouldn’t matter so much as the genetic information gleaned from sequencing the tumor.
