brain

Men aren't from Mars and women aren't from Venus, but their brains really are wired differently, a new study suggests.

The research, which involved imaging the brains of nearly 1,000 adolescents, found that male brains had more connections within hemispheres, whereas female brains were more connected between hemispheres. The results, which apply to the population as a whole and not individuals, suggest that male brains may be optimized for motor skills, and female brains may be optimized for combining analytical and intuitive thinking.

"On average, men connect front to back [parts of the brain] more strongly than women," whereas "women have stronger connections left to right," said study leader Ragini Verma, an associate professor of radiology at the University of Pennsylvania medical school. But Verma cautioned against making sweeping generalizations about men and women based on the results.

Previous studies have found behavioral differences between men and women. For example, women may have better verbal memory and social cognition, whereas men may have better motor and spatial skills, on average. Brain imaging studies have shown that women have a higher percentage of gray matter, the computational tissue of the brain, while men have a higher percentage of white matter, the connective cables of the brain. But few studies have shown that men's and women's brains are connected differently.

In the study, researchers scanned the brains of 949 young people ages 8 to 22 (428 males and 521 females), using a form of magnetic resonance imaging (MRI) known as diffusion tensor imaging, which maps the diffusion of water molecules within brain tissue. The researchers analyzed the participants as a single group, and as three separate groups split up by age.

As a whole, the young men had stronger connections within cerebral hemispheres while the young women had stronger connections between hemispheres, the study, detailed today (Dec. 2) in the journal Proceedings of the National Academy of Sciences, found. However, the cerebellum, a part of the brain below the cerebrum that plays a role in coordinating muscle movement, showed the opposite pattern, with males having stronger connections between hemispheres.

Roughly speaking, the back of the brain handles perception and the front of the brain handles action; the left hemisphere of the brain is the seat of logical thinking, while the right side of the brain begets intuitive thinking. The findings lend support to the view that males may excel at motor skills, while women may be better at integrating analysis and intuitive thinking.

"It is fascinating that we can see some of functional differences in men and women structurally," Verma told LiveScience. However, the results do not apply to individual men and women, she said. "Every individual could have part of both men and women in them," she said, referring to the connectivity patterns her team observed.

When the researchers compared the young people by age group, they saw the most pronounced brain differences among adolescents (13.4 to 17 years old), suggesting the sexes begin to diverge in the teen years. Males and females showed the greatest differences in inter-hemisphere brain connectivity during this time, with females having more connections between hemispheres primarily in the frontal lobe. These differences got smaller with age, with older females showing more widely distributed connections throughout the brain rather than just in the frontal lobe.

Currently, scientists can't quantify how much an individual has male- or female-like patterns of brain connectivity. Another lingering question is whether the structural differences result in differences in brain function, or whether differences in function result in structural changes.

The findings could also help scientists understand why certain diseases, such as autism, are more prevalent in males.

Rare Cancers in Children

Although, the incidence of cancer is significantly low in children, there are some rare forms of cancer that have affected infants, kids and adolescents. Read on to know such cancer forms.



Rare Cancer of Abdomen in Children

Carcinoma of the Adrenal Cortex— This type of cancer is termed as adrenocortical tumour and is  most commonly encountered in the foetus and infants. Adrenal Cortex is the cortical part of the adrenal gland, which is responsible for the production of corticosteroid and androgen hormones. This type of cancer is classified as adrenocortical carcinomas and adrenocortical adenomas. Occurrence of adrenocortical carcinomas may trigger continuous secretion of hormones developing masculine characteristics in the person irrespective of gender.
Carcinoma of the Stomach— This is among the most unusual cancers found in kids. Asian kids are at an increased risk of gastric cancer, especially Japanese and Chinese kids. When a child is diagnosed with anaemia is when he/she is diagnosed with cancer of the stomach, which is also known as gastric cancer.  This type of cancer presents symptoms, such as pain in the upper abdomen, vomiting, nausea, change in bowel habits and tiredness. It often leads to reduced appetite and weight loss.
Cancer of the Pancreas— Also known as pancreatoblastoma, it is a rare type of cancer that is encountered by children and adolescents, though its incidence until now has been very rare. First described in 1959, the cancer of the pancreas is common amongst Asians  compared with the whites. The cancer of the pancreas can further be classified into squamous cell carcinomas, acinic cell carcinomas, liposarcomas, lymphomas and malignant insulinomas and glucagonomas.


Rare Head and Neck Cancer in Children



Nasopharyngeal Carcinoma— This unsual type of cancer develops in the epithelium of the nasopharynx, which is the lining of the nasal cavity and throat (pharynx). A very rare cancer in kids below 10 years of age, the cancer of the nasopharynx has a higher incidence in adolescents compared with other age groups.  The kids of North African and Southeast Asian origin have greater possibilities of developing this type of cancer than children of other origins.
Esthesioneuroblastoma— First characterised in 1924, this unusual cancer form arises from the olfactory epithelium and metastasises to the nasal cavity. The average age of the affected children lies within the adolescent age group .i.e, 12 to 19 years. The youngest child, who was diagnosed with esthesioneuroblastoma, was two years old. This type of cancer presents symptoms, such as those of loss of taste and vision.
Thyroid Tumours— Tumour of the thyroid gland is termed as adenomas or carcinomas. Adenomas are benign whereas carcinomas are malignant. Adenoma leads to enlarged growth of the gland. Malignant carcinoma metastasises to the lungs or lymph nodes present in the neck. Thyroid nodules in children are five times more susceptible than those in adults.


Other Rare Cancers of Childhood

Oral Cancers.
Salivary Gland Tumours.
Malignant Rhabdoid Tumours.
Melanotic Neuroectodermal Tumours of Infancy.
Laryngeal Cancer and Papillomatosis.
Retinoblastoma.

10000 times stronger killer of CANCER than Chemo


"10000 times stronger killer of CANCER than Chemo".. do share it.. can save many lives, fill up hopes and build confidence in the patients...
The Sour Sop or the fruit from the graviola tree is a miraculous natural cancer cell killer 10,000 times stronger than Chemo.

Why are we not aware of this? Its because some big corporation want to make back their money spent on years of research by trying to make a synthetic version of it for sale.

So, since you know it now you can help a friend in need by letting him know or just drink some sour sop juice yourself as prevention from time to time. The taste is not bad after all. It’s completely natural and definitely has no side effects. If you have the space, plant one in your garden.
The other parts of the tree are also useful.

The next time you have a fruit juice, ask for a sour sop.

How many people died in vain while this billion-dollar drug maker concealed the secret of the miraculous Graviola tree?

This tree is low and is called graviola ! in Brazi l, guanabana in Spanish and has the uninspiring name “soursop” in English. The fruit is very large and the subacid sweet white pulp is eaten out of hand or, more commonly, used to make fruit drinks, sherbets and such.

The principal interest in this plant is because of its strong anti-cancer effects. Although it is effective for a number of medical conditions, it is its anti tumor effect that is of most interest. This plant is a proven cancer remedy for cancers of all types.

Besides being a cancer remedy, graviola is a broad spectrum antimicrobial agent for both bacterial and fungal infections, is effective against internal parasites and worms, lowers high blood pressure and is used for depression, stress and nervous disorders.

If there ever was a single example that makes it dramatically clear why the existence of Health Sciences Institute is so vital to Americans like you, it’s the incredible story behind the Graviola tree..

The truth is stunningly simple: Deep within the Amazon Rainforest grows a tree that could literally revolutionize what you, your doctor, and the rest of the world thinks about cancer treatment and chances of survival. The future has never looked more promising.

Research shows that with extracts from this miraculous tree it now may be possible to:
* Attack cancer safely and effectively with an all-natural therapy that does not cause extreme nausea, weight loss and hair loss
* Protect your immune system and avoid deadly infections
* Feel stronger and healthier throughout the course of the treatment
* Boost your energy and improve your outlook on life

The source of this information is just as stunning: It comes from one of America ‘s largest drug manufacturers, th! e fruit of over 20 laboratory tests conducted since the 1970′s! What those tests revealed was nothing short of mind numbing… Extracts from the tree were shown to:

* Effectively target and kill malignant cells in 12 types of cancer, including colon, breast, prostate, lung and pancreatic cancer..
* The tree compounds proved to be up to 10,000 times stronger in slowing the growth of cancer cells than Adriamycin, a commonly used chemotherapeutic drug!
* What’s more, unlike chemotherapy, the compound extracted from the Graviola tree selectivelyhunts
down and kills only cancer cells.. It does not harm healthy cells!

The amazing anti-cancer properties of the Graviola tree have been extensively researched–so why haven’t you heard anything about it? If Graviola extract is

One of America ‘s biggest billion-dollar drug makers began a search for a cancer cure and their research centered on Graviola, a legendary healing tree from the Amazon Rainforest.

Various parts of the Graviola tree–including the bark, leaves, roots, fruit and fruit-seeds–have been used for centuries by medicine men and native Indi! ans in S outh America to treat heart disease, asthma, liver problems and arthritis. Going on very little documented scientific evidence, the company poured money and resources into testing the tree’s anti-cancerous properties–and were shocked by the results. Graviola proved itself to be a cancer-killing dynamo.
But that’s where the Graviola story nearly ended.

The company had one huge problem with the Graviola tree–it’s completely natural, and so, under federal law, not patentable. There’s no way to make serious profits from it.

It turns out the drug company invested nearly seven years trying to synthesize two of the Graviola tree’s most powerful anti-cancer ingredients. If they could isolate and produce man-made clones of what makes the Graviola so potent, they’d be able to patent it and make their money back. Alas, they hit a brick wall. The original simply could not be replicated. There was no way the company could protect its profits–or even make back the millions it poured into research.

As the dream of huge profits evaporated, their testing on Graviola came to a screeching halt. Even worse, the company shelved the entire project and chose not to publish the findings of its research!

Luckily, however, there was one scientist from the Graviola research team whose conscience wouldn’t let him see such atrocity committed. Risking his career, he contacted a company that’s dedicated to harvesting medical plants from the Amazon Rainforest and blew the whistle.

Miracle unleashed
When researchers at the Health Sciences Institute were alerted to the news of Graviola,! they be gan tracking the research done on the cancer-killing tree. Evidence of the astounding effectiveness of Graviola–and its shocking cover-up–came in fast and furious….

….The National Cancer Institute performed the first scientific research in 1976. The results showed that Graviola’s “leaves and stems were found effective in attacking and destroying malignant cells.” Inexplicably, the results were published in an internal report and never released to the public…

….Since 1976, Graviola has proven to be an immensely potent cancer killer in 20 independent laboratory tests, yet no double-blind clinical trials–the typical benchmark mainstream doctors and journals use to judge a treatment’s value–were ever initiated….

….A study published in the Journal of Natural Products, following a recent study conducted at Catholic University of South Korea stated that one chemical in Graviola was found to selectively kill colon cancer cells at “10,000 times the potency of (the commonly used chemotherapy drug) Adriamycin…”

….The most significant part of the Catholic University of South Korea report is that Graviola was shown to selectively target the cancer cells, leaving healthy cells untouched. Unlike chemotherapy, which indiscriminately targets all actively reproducing cells (such as stomach and hair cells), causing the often devastating side effects of nausea and hair loss in cancer patients.

…A study at Purdue University recently found that leaves from the Graviola tree killed cancer cells among six human cell lines and were especially effective against prostate, pancreatic and lung cancers…. Seven years of silence broken–it’s finally here!
