Beards Keep You Young, Healthy & Handsome, Says Science
Gentlemen, they’re not just for hipsters and the homeless any more. While both dead sexy and totally awesome, beards are also a boon to your overall health. Researchers discovered that men with beards and moustaches actually enjoy numerous benefits including, but not limited to, instant handsomeness.
A study from the University of Southern Queensland, published in the Radiation Protection Dosimetry journal, found that beards block 90 to 95 percent of UV rays, thereby slowing the aging process and reducing the risk of skin cancer. Got asthma? Pollens and dust simply get stuck in that lustrous facial hair. Additionally, all that hair retains moisture and protects against the wind, keeping you looking young and fresh-faced. What’s more, shaving is usually the cause of ingrown hairs and bacterial infections that lead to acne.
Have you tossed your razor in the trash yet?
To conduct the study, researchers left bearded mannequins, along with less attractive, follically-challenged ones, in the blistering sun of the Australian outback and then compared the amount of radiation absorbed by each.
But don’t forget to take care of those blessed follicles; beards can also spread infection if not properly cared for and make consumption of certain foods (e.g. cheeseburgers, corn on the cob, falafel sandwiches—anything with hummus actually, bagel ‘n’ schmear, syrupy pancakes) rather laborious.
Fuzzy-faced men would be wise to take advantage of beard wash and beard oil, essential tools for looking and feeling your beardy best.

Cabbage patch to soothe sore joints
Could covering your knee with cabbage ease sore joints?
Cabbage, which is shredded and mixed with warm water to form a poultice, has been used as a traditional remedy for joint pain and skin complaints.
Now, doctors are comparing the benefits of a cabbage poultice with diclofenac gel, an anti-inflammatory commonly used to ease joint pain.
Around 80 people with osteoarthritis of the knee will be given the cabbage dressing, the gel or their usual care, in the trial at Universitat Duisburg-Essen, Germany.
Just how cabbage might help is not clear, but it contains glutamine, a constituent of glucosamine – this compound occurs naturally in the body and plays a role in building cartilage.

Smokers can't taste bitter taste of caffeine
Do you smoke or have quit recently? Chances are that you may not taste and appreciate the bitter taste of caffeine in your cup of coffee.
According to research, smokers and those who have quit cannot fully appreciate the full flavour of a cup of coffee because many cannot taste the bitterness of their regular caffeine kick.
It is already known that smoking, and especially the toxic chemicals in tobacco, causes a loss of taste among smokers.
To extend knowledge on the matter, a team of researchers from Pitie-Salpetriere Hospital APHP in France tested the ability of 451 participants to recognise the four basic tastes of sweet, sour, bitter and salty, as well as the intensity of each taste.
The participants were grouped into smokers, non-smokers and people who had quit smoking.
It was found that smoking status had no influence on a person's ability to recognise salty, sweet or sour tastes.
"It did however have an effect on people's ability to taste the bitter taste of caffeine," said Nelly Jacob of the Pitie-Salpetriere Hospital.
One in every five smokers (19.8 percent) could not correctly recognise the taste, while the same happened one in every four times (26.5 percent) that former smokers were put to the test.
Only 13.4 percent of non-smokers could not correctly identify the bitter samples they were asked to taste.
"The accumulation in the body of some tobacco or combustion products may hamper the regeneration of taste buds, and, therefore, still impair a person's ability to recognise certain tastes even after they have stopped smoking," Jacob explained.
The findings were published in Springer's journal Chemosensory Perception.

Now, a nasal spray for depression
A nasal spray has been created to cure depression.The spray delivers a peptide to the right part of the brain to treat depression and holds promise as a potential alternative therapeutic approach, according to research by Canada's Centre for Addiction and Mental Health (CAMH).
CAMH's Fang Liu developed a protein peptide that provided a highly targeted approach to treating depression that she hopes will have minimal side effects.
The peptide was just as effective in relieving symptoms when compared to a conventional antidepressant in animal testing. But the peptide had to be injected into the brain. Taken orally, it would not cross the blood-brain barrier in sufficient concentrations.
"Clinically, we needed to find a non-invasive, convenient method to deliver this peptide treatment. This study marks the first time a peptide treatment has been delivered through nasal passageways to treat depression," Liu said. The peptide treatment interferes with the binding of two dopamine receptors - the D1 and D2 receptor complex.
Liu's team had found that this binding was higher in the brains of people with major depression. Disrupting the binding led to the anti-depressant effects.
The peptide is an entirely new approach to treating depression which has previously relied on medications that primarily block serotonin or norepinephrine transporters.
"This research brings us one step closer to clinical trials," Liu said.
In ongoing lab research, her team is experimenting to determine if they can make the peptide break down more slowly, and travel more quickly in the brain, to improve its anti-depressant effects, she added.
Depression is the most common form of mental illness and one of the leading causes of disability globally. More than 50% of people living with depression do not respond to first-line medication treatment.
Depression affects nearly 121 million people worldwide. It is the second contributor to shorter lifespan for individuals in the 15-44 age group. Women are twice as likely to suffer depression as men and the loss of a partner, whether from death or divorce, was a main factor.

Active mothers have active children, says study
A British study of 500 women and their four-year-olds has found that physically agility in children is related to how active their mothers are.
Parents are strong influences in the lives of young children with patterns of behaviour established in the early years. Researchers found that mothers of toddlers and children with minimal physical activity themselves lacked recommended exercise levels.
For every minute of moderate-to-vigorous activity a mother engaged in, her child was more likely to engage in 10% more of the same level of activity.
If a mother was one hour less sedentary per day, her child may have spent 10 minutes less sedentary per day.
Cambridge University researchers said, "A study of physical activity patterns of women and their four-year-olds reveals a strong association between the two. It also shows that only 53% of mothers engaged in 30 minutes of moderate-to-vigorous activity at least once a week. When it comes to levels of physical activity, it is mothers who set or don't set the pace."
The analysis of the physical activity levels of more than 500 mothers and pre-schoolers assessed using activity monitors to produce accurate data found that the amount of activity that a mother and her child did each day was closely related.
Overall maternal activity levels were strikingly low: only 53% of mothers engaged in 30 minutes of moderate-to-vigorous physical activity at least once a week.
Esther van Sluijs from University of Cambridge said, "Active mothers appear to have active school-aged children who are in turn more likely than their less active peers to have good health outcomes. But there has been little large-scale research into the association between the activity of mothers and that of preschool-aged children.".
Of the 554 mothers whose data was analyzed, many were working and many of the children attended day-care facilities - factors that influenced activity levels of both mothers and children.
Kathryn Hesketh from the University of Southampton added, "We saw a direct, positive association between physical activity in children and their mothers - the more activity a mother did, the more active her child. Although it is not possible to tell from this study whether active children were making their mothers run around after them, it is likely that activity in one of the pair influences activity in the other."

Tuberculosis affects 1 million children annually: Study
Harvard researchers believe that over one million children suffer from tuberculosis annually — twice the number previously thought to have TB.
Experts from the university and Brigham and Women's Hospital fear that one-third of these children may be suffering from drug-resistant tuberculosis that is extremely difficult to treat. The study was published in The Lancet on Sunday.
Pediatric TB is emerging as one of the most neglected areas in tuberculosis; there isn't even special drugs meant for the pediatric population.
In fact, the World Health Organization's Tuberculosis Report 2013 had noted that a child with TB is as likely as an adult with TB to have MDR-TB (multi-drug resistant TB). India too has very little information about the spread of the disease among the pediatric population.
The Harvard study's author Dr Ted Cohen said, "Despite children comprising approximately one-quarter of the world's population, there have been no previous estimates of how many suffer from MDR-TB disease."
He said that the estimate of the total number of new cases of childhood TB is twice that estimated by the WHO in 2011 and three times the number of child TB cases notified globally each year.
Pediatric tuberculosis is one of the most neglected aspects of the TB epidemic.
The researchers used several sources of publicly available data and devised a new method to correct for the chronic under-diagnosis that occurs in children, using conventional TB tests which were designed for and work best on adults. The researchers used two models to estimate both the regional and global annual incidence of MDR-TB in children.
Their findings indicate that around 1,000,000 children developed TB disease in 2010 and of those, 32,000 had MDR-TB.

Experts seek more awareness campaigns for tuberculosis
On the occasion of World TB Day, several programmes were held in the city on Monday. Dr SK Katiyar, former principal of GSVM College organized a seminar on 'Quantiferon TB Gold - Unmasking the Truth'. Dr RP Yadav, chief medical officer, Kanpur Nagar, who was the chief guest on the occasion, showed his concern over rising trend of the MDR TB cases and called for the cooperation of doctors in the private sector to fight this menace.
Dr SK Misra, laproscopic surgeon, spoke on the aims and objectives of the organization which includes that every citizen be made aware of importance of maintaining good health and better living besides fulfilling the need of continuing medical education and updates on medical advancements.
Health awareness programs will be held in city schools apart from free medical check-up camps, road shows in slum areas and interiors of the city, among others.
Dr SK Katiyar, former principal of GSVM and ex-president of National College Chest Physicians (India), Tuberculosis Association of India, and Indian Chest Society, said that in spite of effective anti-TB treatment being available, the overall situation of TB in the country is not good and thousands of people are dying every day due to it.
Dr Katiyar said that this test does not differ much from the existing tuberculine test. Both these tests give information on the TB infection in the body and that these tests cannot discriminate between a TB infection and disease.
It is also not possible by this test to tell us that which TB infected persons are likely to develop disease. During this, in-vitro test blood sample of the patient is mixed with a specific TB antigen and incubated, which leads to the release of interferon gamma which is measured by ELISA.
He said that WHO issued a policy statement on the usefulness of this test in the middle and lower income countries and this document is based on all the available literature and publications, unfortunately most of which was from the higher income countries with low TB infection. It has clearly been said in this document that in countries like ours there is no usefulness of QFT-Gold test and that it does not provide any additional information than what is already done by the tuberculine test. According to the document, besides adults, it is also not useful in the paediatric population and those who are infected with HIV.
A panel discussion and question and answer session was also held on this occasion.
where leproscopic surgeon Dr SK Misra, professor and head of obstetric and gynaecology department of medical college, Kanpur Dr Kiran Pandey, senior physician Dr AC Agarwal and chest physician Dr Bharat Mehrotra participated.
Dr Kiran Pandey told about genital tuberculosis and that TB is one of the important causes of sterility in women in our country. She discussed about the diagnosis of TB in these cases and that QFT-TB Gold has no definitive role in the diagnosis.
Dr AC Agarwal speaking on the occasion said that diabetes and TB are closely linked with each other and the former are more prone to develop TB because of poor immunity and increased sugar levels. He was also of the opinion that QFT-TB Gold has got no advantage over existing tuberculine test. He said that sometimes when these tests are negative they could be more informative that the patient may not have TB but there could be several other reasons for this negative test.
Dr Bharat Mehrotra also said that even in those cases of pulmonary TB who have negative sputum smear examination repeatedly, these tests have no definitive role in diagnosis and there is no advantage of QFT-TB Gold over tuberculine test.

Your unconscious mind can detect a lie
When it comes to detecting deceit, your unconscious mind may be more accurate than conscious thought in pegging truth-tellers and liars, according to a new research.
The findings suggest that conscious awareness may hinder our ability to detect whether someone is lying, perhaps because we tend to seek out behaviours that are supposedly stereotypical of liars, like averted eyes or fidgeting.
However, those behaviours may not be all that indicative of an untrustworthy person, researchers said.
"Our research was prompted by the puzzling but consistent finding that humans are very poor lie detectors, performing at only about 54 per cent accuracy in traditional lie detection tasks," said psychological scientist and study author Leanne ten Brinke, postdoctoral fellow at the University of California, Berkeley's Haas School of Business.
It is a finding that seems at odds with the fact that humans are typically sensitive to how others are feeling, what they're thinking, and what their personalities are like.
Along with UC Berkeley colleague Dayna Stimson and Berkeley-Haas Asst Prof Dana Carney, ten Brinke hypothesised that these seemingly paradoxical findings may be accounted for by unconscious processes.
"We set out to test whether the unconscious mind could catch a liar - even when the conscious mind failed," she said.
The researchers first had 72 participants watch videos of "suspects" in a mock-crime interview. Some of the suspects in the videos had actually stolen a USD 100 bill from a bookshelf, whereas others had not.
However, all of the suspects were instructed to tell the interviewer they had not stolen the money. In doing so, one group of suspects must have been lying, whereas the other group must have been telling the truth.
When the 72 participants were asked to say which suspects they thought were lying and which were telling the truth, they were pretty inaccurate: They were only able to detect liars 43 per cent of the time, and truth-tellers only 48 per cent of the time.
But the researchers also employed widely-used behavioural reaction time tests (one of which is called the Implicit Association Test or IAT) to probe participants' more automatic instincts towards the suspects.
Results published in the journal Psychological Science showed that participants were more likely to unconsciously associate deception-related words (eg "untruthful," dishonest," and "deceitful") with the suspects who were actually lying.
At the same time, participants were more likely to associate truthful words (eg "honest" or "valid") with the suspects who were actually telling the truth.
A second experiment confirmed these findings, providing evidence that people may have some intuitive sense, outside of conscious awareness, that detects when someone is lying.

Peach extract could help restrict breast cancer metastasis
Researchers have shown that treatment with peach extract inhibit breast cancer metastasis.
Texas A and M AgriLife Research Research scientists say that the mixture of phenolic compounds present in the peach extract are responsible for the inhibition of metastasis.
Dr. Luis Cisneros-Zevallos, a food scientist for AgriLife Research in College Station, said that cancer cells were implanted under the skin of mice with an aggressive type of breast cancer cells, the MDA-MB-435, and what we saw was an inhibition of a marker gene in the lungs after a few weeks indicating an inhibition of metastasis when the mice were consuming the peach extract.
He said that furthermore, after determining the dose necessary to see the effects in mice, it was calculated that for humans it would be equivalent to consuming two to three peaches per day.
The study was conducted using the peach variety Rich Lady. However, according to Cisneros-Zevallos, most peach fruit share similar polyphenolic compounds but might differ in content. The study also determined that the underlying mechanism by which peach polyphenols are inhibiting metastasis would be by targeting and modulating the gene expression of metalloproteinases.
The study has been published in the Journal of Nutritional Biochemistry.

You are most prone to heart attacks, stroke at 6.30 am
A new study has found that a person is most likely to suffer a heart attack or stroke at 6.30 am.
Researchers from Boston's Brigham and Women's Hospital and Oregon Health and Science University have blamed the protein, plasminogen activator inhibitor-1 (PAI-1), for the increased risk for cardiovascular events in the morning.
Study author Dr Frank Scheer, from BWH, explained that PAI-1 is at its peak in the body at approximately 6.30 am in a regular 24-hour sleep/wake cycle.
Co-author Dr Steven Shea added that the human circadian system causes a morning peak in circulating levels of PAI-1, independent of any behavioural or environmental influences.
Scheer asserted that it all comes down to our internal body clock when heart attacks and stroke come into the picture.
The research is published in the journal Blood.
