Taste buds linked to Male Fertility

An interesting finding was reported in Proceedings of the National Academies of Sciences. Scientists from the Monell Chemical Senses Center report the interesting finding about the two proteins involved in oral taste detection that not only play a role in taste detection but also have crucial role in sperm development. The two proteins linked are TAS1R3, a component of both the sweet and umami (amino acid) taste receptors, and GNAT3, a molecule involved in converting the oral taste receptor signal into a nerve cell response. While breeding mice for taste-related studies, researchers observed that a group of mice was unable to reproduce that lacked two taste-signaling proteins. The experiments also reveal that this infertility was seen only in males and these proteins previously have been found on testes and sperm but until now their function were unknown.

The research team engineered the mice with missing genes and found that the mice turned fertile proving the connection between the tastebuds and fertility.

Does Sunscreen lotion prevent Skin Aging?

Sunscreen represent defense from solar rays and new evidences show that a daily slathering may not only protect you from skin cancer and sunburn, it may protect your skin from aging. Australian researchers in the study divided the patients under two categories, 903 white adults under age 55 — the average age was 39 — into two groups. One group was asked to apply SPF 15 (or greater) sunscreen on their head, neck, hands and arms every morning, after every bath or shower, after spending a few hours in the sun and after sweating heavily. The other participants could use sunscreen however they wished for. The results were studied by the dermatologists four and a half years later. Images of the subject hands were studied at the start and four and a half years later. Overall, subjects of that group showed 24% less signs of skin aging than the control group.

This anti aging effect of sunscreen was seen in all daily-use participants, no matter what age they were.

Diclofenac, a common painkiller elevates the risk of heart attack and stroke

The UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) has warned stating a common painkiller, diclofenac, raises the risk of heart attack and stroke among patients with serious underlying heart conditions. The most common painkiller drug Diclofenac is sold under colossal trade names such as Diclomax, Defenac, Diclofex, Dyloject, Econac, Enstar, Flamrase, Flamatak, Motifene, Rheumatac, Rhumalgan, Volsaid, and Voltarol. Reviews of Diclofenac and related medicines carried out during 2005, 2006 and 2012 have confirmed that NSAIDs class are associated with a small increased risk of arterial thromboembolic events (blood clots in the arteries) especially in those patients with underlying heart or circulatory conditions.

For all NSAIDs MHRA recommends that these medicines may be used at the lowest effective dose for the shortest period of time necessary to control symptoms.

Sixth sense technology has incredibly increased its usage in the medical field. One such effort is by HQ Inc., who developed patented CorTemp®, an ingestible core body thermometer pill and the RF compatible CorTemp miniaturized data recorder. For people in intense professions, like space travel, different versions of these pills have been already used for some time. But soon it might be adopted by all the technology loving doctors, carrying them in their medical kit. These pills contain tiny sensors and transmitters. Doctors and researchers extend their medical knowledge and join hands with technology that supports the healthcare like core body temperature pill technology for its use in the prevention and detection of heat stress and heat related illness.

The organ system effortlessly monitors, records and reports real-time core body temperature in time-correlation with heart rate accurately, wirelessly and comfortably, every time! Without the usage of catheters, wire connections or probes, scientists, researchers and clinicians can monitor their free of discomfort and confinement.

Sleep less, dream more

Missing sleep tonight may just boost your dreams tomorrow night. The greater sleep intensity is seen among the ones who had deprived sleep. Dreams are successions of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep. Mark Mahowald, a neurologist of the University of Minnesota and director of the Minnesota Regional Sleep Disorders Center in Minneapolis say dreaming is more vivid and certainly increased when there is greater brain activity. Brains are quite complex that they were able to solve the problem of memory processing by dividing the night into two types of sleep, one is now called slow wave sleep (SWS) and one is called rapid eye-movement (REM) sleep.

The study confirms two aspects; the people with less sleep will have high brain activity. And High brain activity will boost REM sleep which is the phase where most of the dreams appear. Still different phases of sleep and dream studies offer much information on the sleep-dream relationships.

Situs Inversus: opposing Nature

Situs inversus a rare congenital disorder in which major visceral organs such as heart is reversed or mirrored from their normal positions. The normal existing arrangement is termed Situs solitus. Leonardo da Vinci first identified and drawn the Dextrocardia, heart being located on right side of thoracic cavity. The condition affects almost all the structures within the thorax and abdomen. The heart is located on the right side of the thorax, the stomach and spleen on the right side of the abdomen and the liver and gall bladder on the left side. The left lung is trilobed and the right lung bilobed, and blood vessels, nerves, lymphatics and the intestines are also transposed.

Situs inversus is generally known to be an autosomal recessive genetic condition found in identical “mirror” twins. The notable Randy Foye, an American basketball player is a victim of Situs Inversus.

Sick leaves shrink the spread of flu

University of Pittsburgh come up with interesting study that showed the importance of Universal paid sick leaves. The researchers simulated an influenza epidemic study in Pittsburgh and surrounding Allegheny County. Study found that universal access to paid sick days would reduce flu cases in the workplace by nearly 6 percent and estimated it to be more effective for small, compared to large, workplaces. The Centers for Disease Control and Prevention recommends people suffering from flu stay home for 24 hours after their fever breaks.

However the access is limited and not all income countries are able to afford sick leaves. The mission to protect the U.S. and the global community against communicable infectious disease threat has lead to this important awareness among the citizens.
