3 US scientists awarded Nobel Prize in Medicine for decoding body clock

Copenhagen, Oct 3: United States scientists Jeffrey C. Hall, Michael Rosbash and Michael W. Young have been awarded the 2017 Nobel Prize in Medicine for their discoveries relating to the biological clock, the Nobel Assembly at Karolinska Institutet in Stockholm said Monday.

Their award-winning scientific discovery explains how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth’s revolutions, a phenomenon also known as the circadian rhythm.

“For many years we have known that living organisms, including humans, have an internal, biological clock that helps them anticipate and adapt to the regular rhythm of the day,” the Nobel assembly said in a statement. “But how does this clock actually work? Jeffrey C. Hall, Michael Rosbash and Michael W. Young were able to peek inside our biological clock and elucidate its inner workings,” it added.

The expression _circadian rhythm_ originates from the Latin words _circa_ meaning “around” and _dies_ meaning “day”.

But just how our internal circadian biological clock worked remained a mystery.

The Nobel Assembly said their decision was based on the scientific trio’s breakthrough that showed “using fruit flies as a model organism, they had isolated a gene that controls the normal daily biological rhythm” and added that “they showed that this gene encodes a protein that accumulates in the cell during the night, and is then degraded during the day.

The “clock” regulates critical functions such as behaviour, hormone levels, sleep, body temperature and metabolism,” the statement said.

Subsequently, the three Nobel winners identified additional protein components of this machinery, exposing the mechanism governing the self-sustaining clockwork inside the cell.

Hall was born in New York in 1945 and works at the University of Maine; Rosbash was born in Kansas in 1944 and works at Brandeis University in Waltham, Massachusetts, while Young, was born in Miami in 1949 and works at the Rockefeller University in New York.

The award includes 9 million Kronen, to be shared among the three winners and reflects a Nobel prize increase for the first time in five years.

The next Nobels to be announced will be the Physics and Chemistry awards on Tuesday and Wednesday while the Literature award will be known on Thursday.

The Peace prize will be revealed on Friday and then the Economy award will be announced on Monday.

All awards are announced in Stockholm except the Peace Prize that is selected and awarded in Oslo, by express request of the Award’s founder, the Swedish industrialist Alfred Nobel (1833-1896), as during his lifetime Norway belonged to the Swedish Crown.

The awards ceremony is due to take place on December 10, coinciding with the anniversary of Nobel’s death during a traditional joint ceremony at Stockholm’s Konserthus and Oslo’s Town Hall.

Breastfeeding secrets every mom should know

Published

Breastfeeding

New Delhi, Jan 23: Breastfeeding seems to be a most natural process, but to some, it may be a challenge. Be patient and feed often, say experts.

Mimansa Malhotra (PT), Lactation Consultant and Lamaze child birth educator on behalf of Philips, and Shilpi Srivastava, Lactation Consultant at Mamma Mia, Fortis Memorial Research Institute, list some tips to keep in mind:

* Try to nurse within the first hour after delivery. That’s when your breast produces colostrum, or first milk. It is packed with nutrients in a small amount. And a small amount is just what a newborn needs.

* Feed often to increase supply. The rule is simple. The lesser you nurse, the lesser milk your body will produce. Ensure you are eating well and getting enough rest. You will need both as your body converts your calories to milk.

* Ensure that when your baby is latched, his/her mouth should take in as much of the dark part of your breast, the areola, as possible. The baby squeezes the milk ducts beneath that area to draw the breast milk out. If your baby is only sucking on the nipple, it will pinch and hurt you. Also, the baby won’t be able to get as much milk.

* Don’t be in a hurry to offer the second breast. It is perfectly alright to leave your baby on the first breast until he/she comes off on his/her own and then offer the second breast. Many babies take one breast at some feedings and both breasts at some. Don’t be rigid and don’t be scared.

* As the experts say breastfeeding is a learning process in which both the counterparts are learning, hence it needs a lot of patience and it may take a few days to weeks to master it.

* During the first week, the baby seems hungry all the time as the baby is trying to cope with the new environment and frequent breast feeds will not only help him in adjusting but also help your body to make more milk to meet baby’s demand.

* Breastfeeding is easier with the right help. It is always advisable to seek help from an expert if you are facing difficulty in breastfeeding, because getting the right help at the right time will make lot of difference to your breastfeeding experience.

* Breastfeeding is an art. Lactation consultant or the healthcare provider will guide you about the technique of latching and holding the baby to make breastfeeding more comfortable for you and for your baby.

* Breastfeeding helps in bonding. It promotes skin to skin contact and lets you spend a lot of time with your new born, helping in understanding his cues and requirements.

Why mothers’ response to baby’s babbling is important

Published

mother babbling baby

New York, Jan 21: Do not stop your little ones when they are babbling. According to new research, babies tend to listen to mothers’ verbal languages that further helps them in learning language skills.

Babies organise mothers’ verbal responses, which promotes more effective language instruction and infant babbling is the key, the research said.

Published in the journal Developmental Science, the study maintained that babies modify their sounds to become more speech-like in response to feedback from their caregivers and that they learn things have names by caregivers naming objects.

Researchers recorded and recombined the vocalisations of 40 nine-month-olds and their mothers, using a “playback paradigm”, to assess how specific forms of sounds and actions by infants influenced parental behaviour.

“We expected that mothers would respond more often when babbling was more mature and they did. The increased rate of response meant more language-learning opportunities for the baby,” said Michael Goldstein, Associate Professor of Psychology at Cornell University.

“The mothers’ speech was also more likely to contain simplified, learnable information about linguistic structure and the objects around the baby. Thus, by varying the form and context of their vocalisations, infants influence maternal behaviour and create social interactions that facilitate learning,” Goldstein said.

The researchers also found that mothers responded more often and more informatively to vocalisations directed at objects than those that were undirected.

“We suspected this would be the case because the object the baby is looking at creates an opportunity for the mother to label it, so she’s more likely to respond with specific information than when a baby is babbling at nothing,” said Rachel Albert, Assistant Professor of Psychology at Lebanon Valley College.

“These results contribute to a growing understanding of the role of social feedback in infant vocal learning, which stands in contrast to the historical view of prelinguistic vocalisations in which babbling was assumed to be motor practice, with no function in the development of communication and language,” Albert added.

– No waiting period for treatments

Some challenges which need to be addressed for patients choosing India as preferred Medical tourism hub

– Improve perception on hygiene and service across the globe
– Ensure quality and service
– Step down facilities for Post Surgical care for recovery. India lacks in centers that can take care of recovery needs post treatments and the patient has to spend more days at a hospital.
– Medical Visa – Procedure to obtain medical visa needs simplification as it can get quite cumbersome as per current regulations

Based on statistics released by the government, Delhi, Maharashtra and Tamil Nadu are the top destinations for visitors travelling for Medical tourism. Chennai, Mumbai and Delhi have the large number of quality hospitals and take the maximum share of the pie as of today. These cities have a several hospitals to choose from and offer good connectivity across the globe.

Medical tourism or health and wellness tourism can be divided in to 2 different types:

Curative: This is where the traveller’s come in for specific treatments, a few of the preferred treatments are listed below:

Cardiac Surgeries including bypass surgeries

Knee / Hip Replacement surgeries

Orthopedic surgeries

Cosmetic surgeries

Ophthalmology

Rejuvenation: Traveller’s want to explore the ancient treatments and traditional medicines offered in India and hence they come to India, a few are listed below

Ayurveda
Yoga
Siddha
Yunani
Naturopathy

Considering that we can excel in various parameters catering to medical tourism, our country has tremendous potential to increase our share in the Medical Tourism segment.

Jay Kantawala, Founder of WIYO Travel says, “Medical tourism in India has been seeing a year on year growth in the past decade and is expected to grow 2 ½ times in the coming 8-10 years and become a US$ 1.6 Billion market in coming decade. This industry will get a boost if Visa process is simplified and simple cross border payments. In addition to this we are seeing Health care institutions opting for certifications for NABH (National Accreditation Board for Hospitals & Healthcare Providers) and JCI (Joint Commission International) accreditations, which help in building trust amongst travelers”.
