Washington, April 29 (ANI): Women who have breastfed in the past face 30 percent reduced risk of breast cancer recurrence, claims a new study.
According to a new Kaiser Permanente study, there was also protective effect of breastfeeding was more pronounced for tumors of particular genetic subtypes, including the most commonly diagnosed of all breast cancers.
Lead author Marilyn L. Kwan, PhD, said that the study, which involved 1,636 women with breast cancer, was the first one where they were aware of that examined the role of breastfeeding history in cancer recurrence, and by tumor subtype.
The researchers found there to be benefits of breastfeeding on expected outcomes among women who were diagnosed with the luminal A subtype of breast cancer, while no significant associations were observed for those with other subtypes. Luminal A tumors include the estrogen-receptor positive (or ER+) breast tumors, which are the most commonly diagnosed of all breast cancers. These tumors are less likely to metastasize, are treatable with hormonal therapy such as tamoxifen and aromatase inhibitors, and generally have better outcomes.
In addition to this women who breastfed were also 28 percent less likely to die from the disease.
Kwan noted that the research showed that breastfeeding had benefits for babies as well as moms. "In fact, the protection was even stronger for women who had a history of breastfeeding for 6 months or more."
The study is published in the Journal of the National Cancer Institute.

Washington, Apr 24 (ANI): A new study has explored that active compound of chili peppers was found to have beneficial effects on liver damage.
The study conducted by European Association for the Study of the Liver found out that capsaicin was found to reduce the activation of hepatic stellate cells (HSCs) in mice models. HSCs are the major cell type involved in liver fibrosis, which is the formation of scar tissue in response to liver damage.
CCl4 is an inorganic compound that was widely used in fire extinguishers, as a precursor to refrigerants and as a cleaning agent. It is now known to be one of the most potent hepatotoxins.
The study demonstrates that capsaicin partially improved liver damage in the BDL mice and inhibited further progression of the injury and in the second group of CCl4-treated mice, capsaicin prevented livers from injury development but did not reduce the fibrosis when it was already established.

Washington, Apr 21 (ANI): A new research has examined that excess use of vitamins and dietary supplements can increase the risk of cancer.

The study conducted by University of Colorado Denver suggested that over-the-counter supplements may actually increase cancer risk if taken in excess of the recommended daily amount.
Tim Byers, associate director for cancer prevention and control at the CU Cancer Center asserted that they were not sure why this was happening at the molecular level but evidence showed that people who take more dietary supplements than needed tend to have a higher risk of developing cancer.
One trial exploring the effects of beta-keratin supplements showed that taking more than the recommended dosage increased the risk for developing both lung cancer and heart disease by 20 percent. Folic acid, which was thought to help reduce the number of polyps in a colon, actually increased the number in another trial.
Byers asserted that when they first tested dietary supplements in animal models they found that the results were promising and eventually they were able to move on to the human populations.
He continued that people can get the daily recommended doses of vitamins and minerals in their diets by eating healthy meal and that many adults who take vitamin supplements may not need them.
Byers concluded that at the end of the day they have discovered that taking extra vitamins and minerals did more harm than good. (ANI)

London, Apr.20 (ANI): A new study has revealed that the number of schoolgirls at risk of emotional problems has risen sharply.
Scientists analyzed questionnaires completed by 1,600 pupils aged 11-13 in 2009, comparing them with similar surveys conducted five years later, BBC News reported.
It was seen that there was 7 percent spike in girls reporting emotional issues while boys' answers remained fairly stable.
Scientists found that social, peer and behavioral problems remained relatively constant for boys and girls across the five years.
They said reasons behind this could include a drive to achieve unrealistic body images perpetuated by social media and an increasing sexualisation of young women.
Funding cuts to mental health services might also be to blame, they suggested.
To help overcome this, researchers suggested teachers should be given the right resources to look out for emotional problems. And they argue mental health services should be more widely available. (ANI)

Washington, April 17 (ANI): Want to avoid

future risk of heart attack? Keep brushing your teeth regularly, says a new study.
Researchers have found that people suffering oral infections also often have cardiovascular problems, and have discovered a particularly strong link between periodontitis and strokes, especially among men and younger people.
A high dose of the commonly prescribed medication, atorvastatin, which boosts blood levels of anti-inflammatory fats called lipoxins and resolvins prevents both gum and heart disease in humans, and even reverses it.
The researchers described the discovery as "exciting and promising" because lipoxins and resolvins also have the advantage of naturally controlling inflammation without suppressing the immune system.
Dr Thomas Van Dyke, of the Forsyth Institute in the United States, said unraveling the role of the oral microbiome and inflammation in cardiovascular disease would likely lead to new preventive and treatment approaches.
Significant epidemiological evidence supports an association between oral infections, particularly periodontitis, and stroke, especially among men and younger individuals. Inflammation plays a major role both in gum and cardiovascular disease.
However, over-the-counter non steroidal anti-inflammatory drugs such as ibuprofen can produce significant cardiovascular side effects, which means it is crucial alternative therapies are found.
Dr Van Dyke recommends people take better care of their teeth to potentially lower their risk of cardiovascular disease and other health problems.
The findings are published in the journal Trends in Endocrinology and Metabolism. (ANI)

Washington, April 15 (ANI): Smoking can make people crave alcohol to the point where they become addicted to it.
Senior author and biologist at The Scripps Research Institute (TSRI), Oliver George, said conducted a study using rat model sand said that it was a "vicious cycle" where nicotine made people crave alcohol to reward the brain and reduce stress.
The team first tested whether nicotine exposure could affect alcohol-drinking behavior in rat models. They started with two groups of male rats where both groups were given access to alcohol to establish the baseline of how much they would drink. The rats drank a little bit, perhaps the equivalent of one or two beers for a human, but they stopped before showing signs of drunkenness.
After this, the researchers used alcohol vapor to induce alcohol dependence in one group of rats. Dependence developed in about two months. In subsequent tests where alcohol was freely available, these rats consumed the equivalent of a six-pack of beer and had blood alcohol levels close to three times the legal limit for humans.
The second group of rats were exposed to both nicotine and alcohol vapor. These rats developed alcohol dependence much faster-and they began drinking the equivalent of a six-pack in just three weeks.
The researchers then offered the rats alcohol with the bitter compound quinine added to see if they could stop the rats from drinking. Most rats decreased their alcohol consumption to avoid the bitter taste, but the nicotine-exposed rats just kept drinking. This indicated that their behavior was compulsive, much like alcoholism in humans.
Using further neurological studies, George and his colleagues tracked this compulsive behavior to the activation of "stress" and "reward" pathways in the brain.
The compulsive alcohol consumption and neurological pathways seen in the new study suggest that alcohol works with nicotine to further activate the brain's reward system and dampen the stress of nicotine exposure.
The study is published in The Journal of Neuroscience. (ANI)

Washington, Apr.12 (ANI): A new study has revealed that blueberries may help treat post-traumatic stress disorder (PTSD).
Ebenezer et al. have previously demonstrated that SSRIs increase levels of serotonin (5-HT) and the neurotransmitter norepinephrine (NE) and that the increased NE might reduce the effectiveness of SSRI therapy.
In the new study, researchers at Louisiana State University looked at the ability of blueberries to modulate neurotransmitter levels in a rat model of PTSD. Researchers supplemented some of the rats with a blueberry-enriched (2 percent) diet and others with a control diet. A third control group did not have PTSD and received a standard diet (without blueberries).
They found that PTSD rats who did not receive blueberries demonstrated a predictable increase in NE and 5-HT when compared with the control group. However, the PTSD rats that received blueberries showed a beneficial increase in 5-HT with no effect on NE levels, suggesting that blueberries could effectively modulate neurotransmitters in PTSD.
These findings indicated that non-pharmacological approaches might modulate neurotransmitters in PTSD. Further studies to understand the molecular mechanism of neuro-protection by BB could provide a potential therapeutic target for the treatment of PTSD. (ANI)
