Researchers show how hematopoietic stem cells detect and react to infections

Researchers at the University of Zurich have shown for the first time that hematopoietic stem cells detect infectious agents themselves and begin to divide - that is, without signals from growth factors.

Study: Response to combination immunotherapy in melanoma depends on proportion of immune cells

Whether a melanoma patient will better respond to a single immunotherapy drug or two in combination depends on the abundance of certain white blood cells within their tumors, according to a new study conducted by UC San Francisco researchers joined by physicians from UCSF Health.

Researchers find new way to protect stem cells from inflammation during wound repair

Scientists have found a new way to protect stem cells from harsh inflammation during wound repair. In a study recently published in the journal Cytotherapy, researchers in India discovered that treating mice with a common anti-inflammatory drug called celecoxib promoted stem cell survival and healing when they injected the cells into wounds.

Targeting risk factors throughout life stages could prevent 35% of dementia cases, study reveals

A study published in The Lancet, on July 20th 2017, reveals that 1 out of 3 dementia cases are preventable when risk factors are targeted beginning from childhood.

Methicillin use not to blame for MRSA, say researchers

The introduction of methicillin into clinical practice is not what caused the emergence of methicillin resistant Staphylococcus aureus (MRSA), report researchers. According to a collaborative study by the University of St Andrews, University of Dundee and the Wellcome Trust Sanger Institute, MRSA existed long before clinicians started using the antibiotic.

Risk of caesarean reduced by healthy diet and physical activity during pregnancy, study finds

A new study published by The BMJ, on 19th July 2017, states that encouraging healthy diets and physical activity during pregnancy can restrict excess gain of weight as well as reduce the chance of having caesarean sections.

Researchers identify striking contrasts in how groups of neurons function during decision making

By training mice to perform a sound identification task in a virtual reality maze, researchers at Harvard Medical School and the Istituto Italiano di Tecnologia (IIT) have identified striking contrasts in how groups of neurons in different cortex regions of the brain function during decision making.

Engineered macrophages invade and engulf tumor cells in mouse models

One reason cancer is so difficult to treat is that it avoids detection by the body. Agents of the immune system are constantly checking the surfaces of cells for chemical signals that say they belong, but cancer cells express the same chemical signals as healthy ones.

CU Boulder study sheds new light on mechanism behind radiation-induced bystander effect

More than half of cancer patients undergo radiotherapy, in which high doses of radiation are aimed at diseased tissue to kill cancer cells.

Research shows how the brain can become adaptive based on training

Practice might not always make perfect, but it's essential for learning a sport or a musical instrument. It's also the basis of brain training, an approach that holds potential as a non-invasive therapy to overcome disabilities caused by neurological disease or trauma.

Study shows how cancer cells force normal cells to act like viruses to enable tumor growth

In a study that could explain why some breast cancers are more aggressive than others, researchers say they now understand how cancer cells force normal cells to act like viruses – allowing tumors to grow, resist treatment, and spread.

Titanium dioxide nanoparticles can intensify inflammatory reaction in patients with colitis

Titanium dioxide, one of the most-produced nanoparticles worldwide, is being used increasingly in foodstuffs.

IBS scientists create first nanoparticle-based tissue adhesive to seal bleeding and guide surgery

As open surgery has gradually been replaced by minimally-invasive and image-guided procedures, tissue adhesives are taking the place of sutures and surgical staples.

Researchers identify new way to increase immune response against cancer and infections

An international research team led by Université de Montréal medical professor Christopher Rudd, director of research in immunology and cell therapy at Maisonneuve-Rosemont Hospital Research Centre, has identified a key new mechanism that regulates the ability of T-cells of the immune system to react against foreign antigens and cancer.

Research shows how dietary essential fatty acids can help treat Alzheimer’s, other diseases

Understanding how dietary essential fatty acids work may lead to effective treatments for diseases and conditions such as stroke, Alzheimer's disease, age-related macular degeneration, Parkinson's disease and other retinal and neurodegenerative diseases.

Exercise may not be equally effective in males and females, research shows

Healthcare practitioners regularly prescribe diet and exercise as a method for patients to lose weight. But exercise might not be equally effective in males and females, according to new research conducted at the University of Colorado, Anschutz Medical Campus.

Researchers uncover new mechanism that promotes growth of blood vessels in tumors

Cancer cells have an enormous need for oxygen and nutrients. Therefore, growing tumors rely on the simultaneous growth of capillaries, the fine branching blood vessels that form a supply network for them.

A heart-healthy diet may lower risk of cognitive impairment in old age, studies suggest

A diet designed to improve cardiovascular health is associated with improved cognitive maintenance in old age, say researchers. The finding comes from four large-scale, population-based studies that were reported on at the 2017 Alzheimer’s Association International Conference (AAIC) in London.

Adding estrogen in the brain may improve health in obese menopausal women

Researchers at the University of Cincinnati (UC) have found that adding estrogen in the brain may improve health in obese females after menopause.

Low-dose anxiolytics can ameliorate social disadvantage related to trait anxiety

Psychologists speak of anxiety in two forms: "state" anxiety, which refers to anxiety arising from a particular situation; and "trait" anxiety, which refers to anxiety as part of a person's overall personality.
