BATTLING BALDNESS

Some men look in the mirror and regard a receding hairline with distress, wondering if there is a cure for baldness. Currently, the only truly effective medically proven way to arrest hair loss is to lower dihydrotestosterone (DHT) levels. DHT is a form of testosterone that regulates beard growth and hair loss. Higher levels of DHT produce fuller beards at the cost of male pattern baldness. Lower levels of DHT ensure a full head of hair at the cost of the inability to grow a beard.

HACKING THE HUMAN BRAIN

Many people enjoy visiting various Web sites and apps that challenge the brain by luring them deeper and deeper into cyber space. Cyber addiction comes in several forms, but all impact the brain. The past two decades have acquainted many people with the concept of hacking. It is why people strive to protect their computers and smartphones from outside sources trying to break in to steal information, implant malware and preocupy their lives.

HEART ATTACK AND MEN

According to the American Heart Association (AHA), more than one in three adult men has heart disease. Men around the age of 55 years are more likely than women to experience a heart attack.  Men often ignore the symptoms of a heart attack because they are uncertain about what they are feeling and don’t want to be embarrassed by a simple diagnosis, such as heartburn. According to the Centers for Disease Control and Prevention (CDC), 50 percent of men who die from coronary heart disease....

Experts have found cells within the malignant brain tumor, called glioma, rely on fats to fuel growth, which contradicts previous scientific belief that tumor cells require mainly sugars to make energy. Glioma is the most common form of primary malignant brain tumor in adults and remains one of the hardest-to-treat cancers. Dr. Elizabeth Stoll with Newcastle University’s Institute of Neuroscience is the lead author of the groundbreaking study. In the study, scientists showed glioma cells grow more slowly if they are treated with a drug known as etomoxir, which prevents the cells from making energy with fatty acids.


Australian researchers claim they have discovered an existing medication (denosumab) that could potentially prevent breast cancer in women carrying the faulty BRCA1 gene. This would mean women with high genetic risk of breast cancer have the option to delay or prevent the disease without making the big decision to have their breasts surgically removed. The identification of these cells means doctors can try to inactivate them before they become cancerous by targeting them with denosumab.


Dr. Shana Kelley at the University of Toronto developed an extremely sensitive blood test that uses sensors on a chip to detect cancer mutations. This non-invasive test is fast and simple to perform. It is now being developed as an alternative to tissue biopsies to detect cancer, monitor how patients respond to therapy and personalize treatment decisions.


Pain from advanced cancer that has spread to the bone can be treated with radiation therapy; however, the pain can temporarily get worse before getting better. Dr. Edward Chow of the Sunnybrook Research Institute in Toronto and the NCIC Clinical Trials Group based at Queen’s University in Kingston led a clinical trial showing the steroid dexamethasone could prevent pain flare-ups from radiation therapy.

According to experts, a drug made from tree bark is being combined with radiation therapy to cure cancer. The drug, called combretastatin, is derived from the bark of an African bush willow and leaves normal blood vessels untouched. It works by destroying developing blood vessels, which tumors generate to supply themselves. Used on its own, however, it leaves a “rim” of cancerous cells at the edge, allowing the disease to return.


The results were published in the journal Cancer Research. Dr. Barbara Pedley, head of tumor biology at the Cancer Research Campaign’s targeting and imaging group at the Royal Free Hospital and University College Medical School in London, said, “This combination can produce long-term cures. Scientists believed the outer tumor cells might rely on the body’s normal blood vessels, which is why combretastatin could not kill them.” Experts now hope to start human trials of the combination therapy as the next stage.


An international study found a combination of two drugs that helped allow the immune system to fight cancer, ipilimumab and nivolumab, stopped the deadly skin cancer melanoma from advancing for nearly a year in 58 percent of cases. (Though a skin cancer, melanoma can spread to the lungs, liver, bone, lymph nodes and brain.) The study was designed and led by Memorial Sloan-Kettering Cancer Center in New York City.

OVERVIEW: BREAKTHROUGHS IN CANCER RESEARCH

New research on prostate cancer sufferers shows stopping the disease could be as simple as “switching off ” a molecule known as DNA- PKcs, which could knock out major pathways that control metastasis before it begins. It is a type of enzyme known as a repair kinase that fixes broken or mutated DNA strands in cancer cells. Because of this enzyme, defective cells that should normally self-destruct are kept alive.


A recent study appears to show that a revolutionary approach to treating cancer using DNA tests can shrink tumors at six times the rates of conventional medicine. This means around one in three women who are currently undergoing grueling rounds of chemotherapy could be spared this drastic treatment because of clues in their genetic profile. The findings, presented at the latest American Society of Clinical Oncology meeting in Chicago, come from 346 early stage clinical trials, which used precision methods. Experts said treatment on the basis of DNA tests could become the norm within five years. Clinical trials involving more than 13,000 patients found those given treatment using the targeted methods saw their disease stalled and tumors shrink at rates far beyond those of standard treatment.
