The Indian Transfer Student to an American School

It was the first day of school and a new student named Chandrashekhar Subrahmanyam entered the fourth grade.

The teacher said, "Let's begin by reviewing some American History. Who said "Give me Liberty , or give me Death"? She saw a sea of blank faces, except for Chandrashekhar, who had his hand up: "Patrick Henry, 1775" he said. "Very good! Said the teacher.

Who said "Government of the People, by the People, for the People, shall not perish from the Earth?" Again there was no response except from Chandrashekhar. "Abraham Lincoln, 1863" said Chandrashekhar.

The teacher snapped at the class, "Class, you should be ashamed. Chandrashekhar, who is new to our country, knows more! About its history than you do."

She heard a loud whisper: "F**k the Indians". "Who said that?" she demanded. Chandrashekhar put his hand up. "General Custer, 1862." At that point, a student in the back said, "I'm gonna puke" The teacher glares around and asks "All right! Now, who said that?" Again, Chandrashekhar says, "George Bush Sr to the Japanese Prime Minister in 1991"

Now furious, another student yells, "Oh yeah? S*ck this!" Chandrashekhar jumps out of his chair waving his hand and shouts to the teacher, "Bill Clinton, to Monica Lewinsky, 1997!" Now with almost mob hysteria someone said "You little shit, if you say anything else, I'll kill you." Chandrashekhar frantically yells at the top of his voice, "Gary Condit to Chandra Levy, 2001."

The teacher Fainted, and as the class gathered around the teacher on the floor, someone said, "Oh shit, we're f**ked!" And, Chandrashekhar said quietly, "George Bush, Iraq , 2005."

Indian Herbal Remedy- Cancer Hope



An Indian herbal remedy could one day be used to help fight pancreatic cancer, scientists hope. A team at the University of Pittsburgh Cancer Institute found extracts of triphala slowed the growth of human pancreatic tumours grafted onto mice.
The findings, presented recently at the annual meeting of the American Association for Cancer Research, offer hope that one day a treatment might be developed. But experts have warned the research is still at a very early stage.Triphala is a herbal preparation used in the traditional Indian medicine system Ayurveda. It contains the dried and powdered fruits of three plants, and it is said to ease intestinal-related disorders, promoting good digestion.Triphala triggered the cancerous cells to die off and significantly reduced the size of the tumors. Previous studies have shown triphala to have an anti-cancer activity in cell cultures, and the new research found this effect also worked in mice fed the herb preparation, without damaging normal pancreatic cells. The team fed mice grafted with human pancreatic tumours a triphala solution five days per week. After four weeks they compared the tumour size and protein contents of the tumours with those of a control group of mice that had not received the triphala. They found that the tumours in triphala-treated mice were half the size of those in the untreated mice.
The also found the treated mice tumour cells had higher levels of proteins associated with apoptosis - the process by the which the body normally disposes of damaged, old of unneeded cells. In cancer cells this process is often faulty, allowing the tumours to divide rapidly without any cells dying.
More research will investigate if the findings in mice can be extended. Further testing revealed that triphala had also activated tumour-suppressor genes, but did not negatively affect normal pancreatic cells. Their results demonstrated that triphala has strong anti-cancer properties given its ability to induce apoptosis in pancreatic cancer cells without damaging normal pancreatic cells.
Pancreatic cancer is the sixth most common cause of cancer death. It is difficult to treat and survival rates are very low - the latest figures show that the length of time between diagnosis and death is usually less than six months. Much more work needs to be done to see if triphala will work in humans. Experts said researching new treatments for pancreatic cancer was important, but warned the current research is still at an early stage.

Baby Boy or Baby Girl?

A slightly greater number of males than females are born worldwide every year. In recent decades, although there are still more baby boys born than girls, there has been an apparent decline in the ratio of male to female newborns in several industrialized countries, including Canada, Denmark, England, Germany, Japan and the United States. That has led researchers to ask: Are there any factors that can influence the probability of giving birth to a baby boy or girl? A new study from the Harvard School of Public Health (HSPH) and Karolinska Institutet in Stockholm, Sweden, found that mothers who experienced an increase in weight from the beginning of the first pregnancy to the beginning of the second pregnancy may be slightly more likely to give birth to a baby boy during their second pregnancy. The study appears online September 24, 2007 in the journal Fertility & Sterility.

"The results are provocative because few biological factors are known in humans to influence the chances of either conceiving or carrying to term a baby boy or girl. Our study suggests that maternal nutritional factors might play a role," said Eduardo Villamor, assistant professor of international nutrition at HSPH and lead author of the study. Some prior studies had looked at what factors might influence the sex ratio, but evidence of causality has been weak. Parental smoking, for example, has been associated with both lower and higher sex ratios. Maternal nutritional status had been studied, but there was little evidence to support a causal relationship with the sex ratio. One of the hypotheses that the authors of this study wanted to test was whether the increase in maternal obesity in several industrialized countries could play a role in the declining sex ratio. Their study found the opposite--maternal weight gain seemed to favor the birth of boys.

The study population, drawn from the Swedish Birth Registry, included 220,889 women who had successive pregnancies between 1992 and 2004 (live births and stillbirths were included). The researchers analyzed the change in women's body mass index (BMI) between the first and second pregnancies. (BMI is weight in kilograms divided by the square of height in meters.) The male to female sex ratio of the second pregnancy increased linearly with the amount of weight change from the first to second pregnancy, from 1.024 in women who lost more than 1 unit BMI to 1.080 in women who gained 3 or more units (a male to female sex ratio of 1.000 would indicate an equal number of boys and girls being born). The trend was independent of obstetric complications, maternal smoking, parental age, length of the interpregnancy interval and the sex or survival status of the first-born child. The data suggest that interpregnancy weight gain appears related to a slight increase in the probability of giving birth to a baby boy during a second pregnancy. The obesity epidemic does not appear to explain the observed decline in the sex ratio in some industrialized countries, which indicates that there are factors still unknown influencing the probability of giving birth to boys or girls.

The authors are careful to note that women should not gain weight to try to influence the sex of their baby. "Weight gain before pregnancy carries significant risks to the mother and the baby, and should not be practiced to influence the odds of having a boy," said Villamor. "Other factors of which weight gain is only an indicator could be at play here."

You cannot beat age

A report published by the US Centers for Disease Control and Prevention (CDC) shows that the younger a woman is when she uses assisted reproductive technology (ART), the more likely she is to become pregnant and have a live birth using her own eggs. The report defines ART as procedures in which both egg and sperm are handled in a laboratory, and says the majority of ART treatments its data include refers to IVF. The CDC's annual report,used data for the year 2002 collected from 391 of the 428 fertility clinics in the US. The report, called '2002 Assisted Reproductive Technology Success Rates', showed that, in 2002, 45,751 live births were achieved from 115,392 ART procedures performed in the US. This was an increase from the previous year's figures, when there were 40,687 live births from 107,758 treatments. Overall, the per-cycle ART success rate in 2002 was 35 per cent, compared to 28 per cent in 1996.The 2002 data show that 37 per cent of women who undergo ART using their own, fresh eggs when they are below the age of 35, had a live birth. This is compared with 31 per cent of women aged between 35 and 37; 21 per cent of women aged between 38 and 40; 11 per cent of women aged between 41 and 42 and just four per cent for women older than 42. However, the report also showed that the age of the woman undergoing ART had 'little effect' on success rates if donated eggs were used. In 2002, the live birth rate for all ART procedures where donated eggs were used was 50 per cent, with the success rate varying only slightly between age groups.
Victoria Wright, one of the authors of the CDC report, said that the data show that 'women in their 20s and early 30s who used ART had the most success with pregnancies, and single live births'. But, she added, 'success rates declined steadily once a woman reached her mid-30s'. She said the figures should act as 'a reminder that age remains a primary factor with respect to pregnancy success, and younger women have greater success than older women, even with technology'

Online Gene Mapping




Two rival companies have launched novel genetic services which, for a price tag of $1000 (Rs. 40,000), will allow people to have their genomes scanned, delivering them personal information about their ancestry, some personal disease risks and other inherited traits.
The first - called deCODEme - was launched by Icelandic company deCODE Genetics on 16 November. Customers send a cheek swab in the post from which DNA can be extracted and analysed for 'over one million variants in your genome', says the website. This is achieved by comparing the customer's genome with a database of thousand's of people's genomes in search for single letter changes - known as SNPs - which can act as signposts for disease risk or other inherited traits. Within 2-3 weeks customers can expect to have access to their personal genome profile via a password-protected online account.
The second - called 23andMe, a reference to the number of pairs of chromosomes in the human genome - was launched on 19 November by a start-up company based in California's Silicon Valley. Similarly, customers send a saliva sample in the post from which DNA can be extracted and analysed for 'nearly 60,000 datapoints on your genome', says the website. 23andMe
co-founder Anne Wojcicki is married to Google co-founder Sergey Brin, who is also a major funder of the venture.
Both websites emphasise that they are not medical-diagnostic services, instead marketing themselves as providers of genetic information. 23andMe even promotes the novelty of being able to 'connect with other 23andMe customers through sharing features', raising the prospect that a kind of gene-based social networking service might evolve, like MySpace or FaceBook.
Some critics have raised concerns over the potential value of a growing body of genetic information to a biotech or insurance company, particularly in light of the fact that 23andMe intends to share anonymised information with outside groups for the purpose of research. While both companies have stressed that they take confidentiality very seriously, promising to accept customers anonymously if specified, there are further concerns that insurance companies might mount legal pressure on such
companies in order to force information disclosure. 'Will they stoutly defend privacy if sued by insurers?' asks The Economist, also worried that any personal genetic information shared with doctors in the US could inadvertently make its way into the hands of insurers via medical records.
Although there are obvious benefits to be gained from the availability of personal genome services, there are also legitimate concerns that such services could cause unnecessary anxiety for some. 'I would think twice before spitting into that vial', says author Nicholas Carr, writing in the Guardian (UK).

Bolo Ta Ra Ra Ra


A sardar went hunting one day in Ontario and bagged three ducks. He put them in the bed of his pickup truck and was about to drive home when he was confronted by an honorary game warden who didn't like sardars.

The game warden ordered the sardar to show his hunting license, and the sardar pulled out a valid Ontario hunting license. The game warden looked at the license, then reached over and picked up one of the ducks, sniffed its butt, and said, "This duck ain't from Ontario. This is a Quebec duck. You got a Quebec huntin' license, boy?" The sardar reached into his wallet and produced a Quebec hunting license.

The game warden looked at it, then reached over and grabbed the second duck, sniffed its butt, and said "This ain't no Quebec duck. This duck's from Manitoba. You got a Manitoba license?" The sardar reached into his wallet and produced a Manitoba hunting license.

The warden then reached over and picked up the third duck, sniffed its butt, and said, "This ain't no Manitoba duck. This here duck's from Nova Scotia. You got a Nova Scotia huntin' license?" Again the sardar reached into his wallet and brought out a Nova Scotia hunting license.

The game warden was extremely frustrated at this point, and he yelled at the sardar "Just where the hell are you from?" The sardar smiled turned around, bent over, dropped his pants, and said, "You tell me, you're the expert."
