Cancer drug quickly reverses Alzheimer’s symptoms in mice

Cancer drug quickly reverses Alzheimer’s symptoms in mice Washington, Feb 10 : In a mice study, a cancer drug was found to quickly reverse the pathological, cognitive and memory deficits caused by the onset of Alzheimer's - a breakthrough in finding cure for the progressive brain disease.

Neuroscientists at Case Western Reserve University School of Medicine discovered that bexarotene, which has been approved for the treatment of cancer by the U. S. Food and Drug Administration for more than a decade, rapidly clears amyloid from the brain and reverses cognitive defects.


4 heart-healthy diet mantras for Valentine’s Day

4 heart-healthy diet mantras for Valentine’s Day Washington, Feb 10 : There are some foods, which when combined can make a romantic yet cardiac-friendly dinner that is perfect for you and your partner on Valentine's Day.

According to researchers, eating a variety of healthy foods in moderation is vital for a heart-healthy diet

How bacterial systems export disease-causing toxins into humans, plants

How bacterial systems export disease-causing toxins into humans, plants Washington, Feb 10 : Scientists have discovered the mechanisms behind some of the bacteria that kill hundreds of thousands every year, possibly paving the way for more effective antibiotics against infections.

With antibiotic resistance on the rise in strains of pathogenic bacteria, innovative strategies are needed to discover ways of treating bacterial infections in both humans and in agriculture.


‘Too posh to push’ not always best for babies’ health

 ‘Too posh to push’ not always best for babies’ health Washington, Feb 10 : A new research has challenged the widely held belief that a caesarean delivery has no health risks for the baby.

The study found that the procedure did not help some preterm babies who were small for gestational age, and may even have contributed to their breathing problems.

The research showed that small for gestational age babies delivered early by C-section had higher rates of respiratory distress syndrome than similar preterm babies who were born vaginally.


How appetite cells in brain respond to fasting

How appetite cells in brain respond to fasting Washington, Feb 9 : There are two vital cell types in the brain that are essential for the regulation of feeding behaviours - agouti-related peptide (AgRP)-expressing neurons and proopiomelancortin
(POMC)-expressing neurons.

Previous work has shown that the AgRP neurons promote feeding and weight gain, while the POMC cells have been linked with appetite suppression and weight loss.

Now a new study uncovers a neural pathway that links fasting with activation of AgRP neurons. The research provides valuable insight into the complex mechanisms that control food-seeking behaviour.


Unusual alliances ‘allow you to wiggle your fingers’

Unusual alliances ‘allow you to wiggle your fingers’Washington, Feb 9 : Some unusual mergers are important for facilitating communication between the brain and muscle, a new study has revealed.

Understanding those relationships should enable better treatment of neuromuscular diseases, such as myasthenia gravis, which prevent muscles from taking orders from your brain, said Dr. Lin Mei, Director of the Institute of Molecular Medicine and Genetics at Georgia Health Sciences University.

During development, neurons in the spinal cord reach out to muscle fibres to form a direct line of communication called the neuromuscular junction.


Fish oil shows potential to prevent psychiatric disorders

 Fish oil shows potential to prevent psychiatric disorders Washington, Feb 9 : A study is now underway to test the effectiveness of Omega 3 fatty acids (fish oil) for treating psychiatric symptoms.

This new study by Researchers at Zucker Hillside Hospital's Recognition and Prevention (RAP) Program, is a randomised double-blind trial that was designed to test whether Omega-3 fatty acids improve clinical symptoms, and help adolescents and young adults (ages 12 to 25) who are at elevated risk for severe psychiatric disorders function better in school, work and other social environments.


Y chromosome ‘may play role in passing heart disease from father to son’

 Y chromosome ‘may play role in passing heart disease from father to son’ Washington, Feb 9 : A common heart disease, which kills thousands of people each year, may be passed genetically from father to son, a new study has said.

According to a study led by the University of Leicester, the Y chromosome, a part of DNA present only in men, plays a role in the inheritance of coronary artery disease (CAD).

The study, led by researchers at the University's Department of Cardiovascular Sciences and Department of Genetics, took four years to complete and was primarily funded by the British Heart Foundation.


Heart disease may lead to prostate cancer

Heart disease may lead to prostate cancerWashington, Feb 9 : Researchers have suggested that coronary artery disease may be a risk factor for prostate cancer.

If the relation is confirmed, the malignancy might be combated in part by lifestyle changes such as weight loss, exercise and a healthy diet, which are known to prevent heart disease.

"What's good for the heart may be good for the prostate," said Jean-Alfred Thomas II, M. D., a post-doctoral fellow in the Division of Urology at Duke Cancer Institute and lead author of the study.

Risk factors of coronary artery disease include inactivity, obesity, high blood pressure and cholesterol, cigarette smoking, and diabetes.


Video-based home exercise can reduce osteoarthritis pain and improve mobility

Video-based home exercise can reduce osteoarthritis pain and improve mobilityWashington, Feb 9 : Video-based home exercise programs can enhance adherence to a prescribed exercise program, can reduce pain, improve physical function, and improve life quality in patients living with knee osteoarthritis, researchers say.

The benefits of exercise in minimizing pain and improving mobility for individuals living with osteoarthritis has been well documented.

In a new study, 107 individuals with diagnosed osteoarthritis in the knee were randomized to either a DVD-based exercise group, or a control group.


Stimulating key site in brain boosts memory

Stimulating key site in brain boosts memory Washington, Feb 9 : UCLA neuroscientists have found that they can strengthen memory in human patients by stimulating a critical junction in the brain.

The finding could lead to a new method for boosting memory in patients with early Alzheimer''s disease.

The UCLA team focused on a brain site called the entorhinal cortex. Considered the doorway to the hippocampus, which helps form and store memories, the entorhinal cortex plays a crucial role in transforming daily experience into lasting memories.


Breastfeeding for at least 6 months can cut risk of childhood obesity

Breastfeeding for at least 6 months can cut risk of childhood obesity Washington, Feb 9 : Children of diabetic mothers have a greater risk of childhood obesity, but breastfeeding for at least six months can reduce this threat, a new study has suggested.

Epidemiologist Tessa Crume, Ph. D., MSPH, and fellow researchers tracked 94 children of diabetic pregnancies and 399 of non-diabetic pregnancies from birth to age 13.

They evaluated the influence of breastfeeding on the growth of body mass index (BMI), an indicator of childhood obesity.

"There are critical perinatal periods for defining obesity risk, pregnancy and early infant life," Crume said.


Anti-obesity drugs with modified lifestyle help weight loss

Anti-obesity drugs with modified lifestyle help weight loss Washington, Feb 9 : Researchers including one of an Indian origin have found that anti-obesity drugs coupled with lifestyle advice are effective in reducing weight and body mass index.

A study led by the University of Leicester looks at the effectiveness of anti -obesity drugs and a modified lifestyle on weight loss and BMI.

The review was based on 94 studies including over 24,000 individuals and assessed how effective the drugs were in terms of weight loss and body mass index at 3, 6 and 12 months.

Two of the included drugs (sibutramine and rimonbant) were withdrawn from use during the review due to possible side effects.


Zinc supplements ‘may slash death risk among kids with pneumonia’

Zinc supplements ‘may slash death risk among kids with pneumonia’ Washington, Feb 8 : Scientists have shown how zinc supplements drastically improve children's chances of surviving respiratory tract infections including pneumonia.

The study also claims that the increase in survival due to zinc on top of antibiotics, was even greater for HIV infected children.

In a double-blind, randomised, placebo-controlled trial, 350 children, aged from six months to five years old, were treated with standard antibiotic therapy at Mulago Hospital. Half the children were given zinc and the other half a placebo.


New laser therapies ‘could make tattoo removal easier’

New laser therapies ‘could make tattoo removal easier’ Washington, Feb 8 : Dermatologists are now discovering new laser therapies for enhancing tattoo removal treatment.

Tattoos, which may affect a person's skin, can be quite difficult to treat or remove.

While lasers have been used to remove tattoos for several years, the procedure requires multiple treatment sessions (typically six to 10 treatments or more) and treatments are painful, requiring a few weeks of healing time between procedures.
