What generates pessimistic mood?

Published

New York, Aug 14: Scientists have identified a brain region that could generate pessimistic moods in disorders such as anxiety or depression that leads people to focus more on the possible downside than the potential benefit in a stressful situation.

In a study tested on animals, researchers at the Massachusetts Institute of Technology (MIT) have found that stimulating caudate nucleus — a brain region linked to emotional decision-making –induced animals to make negative decisions.

The caudate nucleus, has within it regions that are connected with the limbic system, which regulates mood, and sends input to motor areas of the brain as well as dopamine-producing regions.

The study showed that the animals gave far more weight to the anticipated drawback of a situation than its benefit, compared to when the region was not stimulated.

This pessimistic decision-making could continue through the day after the original stimulation.

“We feel we were seeing a proxy for anxiety, or depression, or some mix of the two,” said Ann Graybiel, a professor at the MIT.

In the study, which appeared in the journal Neuron, the team wanted to see if they could reproduce an effect that is often seen in people with depression, anxiety, or obsessive-compulsive disorder.

The team stimulated the caudate nucleus with a small electrical current as animals were offered a reward (juice) paired with an unpleasant stimulus (a puff of air to the face).

The results showed that the cost-benefit calculation became skewed, and the animals began to avoid combinations that they previously would have accepted.

This continued even after the stimulation ended, and could also be seen the following day, after which point it gradually disappeared.

This result suggests that the animals began to devalue the reward that they previously wanted, and focused more on the cost of the aversive stimulus.

“This state we’ve mimicked has an overestimation of cost relative to benefit,” Graybiel noted.

The researchers also found that brainwave activity in the caudate nucleus was altered when decision-making patterns changed.

“There must be many circuits involved,” she said.

“But apparently we are so delicately balanced that just throwing the system off a little bit can rapidly change behaviour.”

wedding bride jewellery

New Delhi, Sep 22: Jewellery choices of the modern-day bride have evolved over the years. Polki or uncut diamonds are the most popular type of jewellery for the ‘pheras’ because of the antiquity and royalty it offers, say experts.

Rohan Sharma, Director of RK Jewellers-South Extension-2, and Shehzad Zaveri, Creative Director of Minawala, have listed tips that help in choosing the right polki jewellery for different bridal looks:

* A small jewellery piece of polki is enough to complete your look. With the changing trends, even in a big fat wedding, brides skip wearing heavy jewellery and have shifted to wearing pastel or light colours on their D-day. Now, it is all about a bride opting for lighter ensembles where she’s free to dance, twirl and hang out with her friends. A polki choker with small earrings and mang tika can make you look equally gorgeous.

* The colour of your lehenga and your chosen bridal jewellery should be in sync with each other. Navratan polki necklace has multi-coloured stone work that go with pastel pink, white and golden trousseau. The bright coloured stones with polki designs are perfect to add colours with your subtle colour outfit.

* A heavy choker or long Raani haars in polki are the perfect styles for a traditional look. A polki necklace studded with south sea pearls, emeralds and rubies is a great choice to complement the lehenga. A bride can pair them with jhumkas, head cover mang tika and nath to complete the look.

* An uncut polki with pearl or kundan work necklace is the right mix for getting a regal look. If you want to steer away from the traditional look, opt for a detachable multi-layered polki necklace that can be worn on lehenga shades like pastel pink, green, gold and blue. You can create a balance by pairing it with over-sized studs or go all out with heavy chandbalis in polka and pearls.

Facial hair transplants the new trend for 21st-century men

Published

Facial hair among men has recently gained popularity in mainstream fashion. With sports and entertainment celebrities sporting the beard, the facial fuzz has become the new swag quotient of the metrosexual man. While the plangent voice with a chiselled body and bushy beard had always been observed as signs of masculinity, social dominance, age and attractiveness, it’s only recently that the metrosexual man has re-discovered the charisma of the fuzz! This has led to the aspirational value of the beard, especially among those who are not sufficiently blessed with the generous crop of facial hair. Enter the new trend in male grooming – The facial hair transplant surgery. With a promise for a natural looking beard, an increasing number of men are turning to this to enhance or restore their facial hair.

Dr Vinod Sonawane,Hair Transplant Surgeon and Managing Director at Bloom Hair Transplant said What are the reasons behind men opting for the transplant: “Beard transplants are a boon to those who are suffering from age, hormone or stress-related issues, impacting their hair growth. In a society where we have the complex perspective of attractiveness towards men with a full beard, with both Indian (Ranveer Singh) and International stars (Nick Jonas), Sports celebrities (Virat Kohli and David Beckham) and Royals and politicians (Prince Harry and Narendra Modi) have kept high standards of masculine charisma. Decoding some of the reasons why facial hair transplant is popular and here to stay for the tall, dark handsome half of the population.”

· Rebuilding self-image after an accident or damage, for e.g. post burns, acne, scars in an accident etc.

· Genetic problems that run in families. If there is a history of some close family member having the condition, it is likely for other members to develop the condition of baldness in the beard area.

· Depression, anxiety, extreme stress and hormonal issues cause bald patches and that leads to hair loss or scanty growth, leading to beard transplant as a lucrative option

Beard hair transplant is a fast-catching trend in India -How the transplant is done:

Sonawane said, “Beard hair transplant, like the other transplants, is a meticulous surgical procedure handled only by professional surgeons. One needs to understand the need and the expectation of the patient and then do the grafting to create a natural looking pattern which fits face proportion, thus enhancing the personality.”

Dr said, “The beard transplant is done mostly by the Follicular Unit Extraction(FUE) technique, where a small group of hair is extracted one by one from a donor site. For the transplant, hair is typically taken from the side or back of the head where it grows finer and is less prone to balding. Transplanted facial hair falls out after roughly 2 weeks, but regrows around 3 months later and can then be treated as natural facial hair.”

Eat fish thrice a week to boost your unborn’s eyesight, brain

Published

pregnant-woman-eating-fish-

London, Sep 21: Pregnant women can enhance the development of their unborn child’s eyesight and brain function by regularly eating fatty fish during the pregnancy, a new study has found.

The findings suggested that infants whose mothers ate fish three or more times a week during the last trimester of their pregnancy fared better than those whose mothers ate no fish or only up to two portions per week.

“The results of our study suggest that frequent fish consumption by pregnant women is of benefit for their unborn child’s development,” said lead author Kirsi Laitinen of the University of Turku in Finland.

“This may be attributable to long-chain polyunsaturated fatty acids within fish, but also due to other nutrients like vitamin D and E, which are also important for development,” Laitinen added.

For the study, published in the journal Pediatric Research, the research team analysed the results of a small group of mothers and their children drawn from a larger study.

The mothers had to keep a regular food diary during the course of their pregnancy. Fluctuations in their weight before and during pregnancy were taken into account, along with their blood sugar level and blood pressure.

The team recorded the levels of nutritional long-chain polyunsaturated fatty acid sources in the mother’s diet and blood serum, and the levels in the blood of their children by the age of one month.

Their children were further tested around their second birthday using pattern reversal visual evoked potentials (pVEP). This sensitive and accurate, non-invasive method is used to detect visual functioning and maturational changes occurring within a young child’s visual system.

“Our study therefore highlights the potential importance of subtle changes in the diet of healthy women with uncompromised pregnancies, beyond prematurity or nutritional deficiencies, in regulating infantile neurodevelopment,” Laitinen noted.
