Washington, Oct. 8 (Xinhua/UNB) -- Exposure to e-cigarette smoke causes mice to develop lung cancer, according to a study published Monday in the Proceedings of the National Academy of Sciences.
Researchers from New York University (NYU) School of Medicine found that nine of 40 (22.5 percent) mice exposed to e-cigarette smoke with nicotine for 54 weeks developed lung cancer, and 23 of them developed bladder hyperplasia, genetic changes that may lead to abnormal tissue growth seen in cancer.
By contrast, only one of the 17 mice exposed to no-nicotine e-cigarette smoke developed hyperplasia.
Previously, researchers argued that chemicals added during the curing of tobacco convert nicotine into nitrosamine -- a carcinogen for mice and humans.
Although the chemicals are 95 percent lower in e-cigarettes, the new study showed that mammalian cells could directly react with nicotine to form nitrosamine, then resulting in DNA damage.
"Our next step in this line of work will be to expand the number of mice studied, to shorten and prolong e-cigarette exposure time, and to further investigate the genetic changes caused by e-cigarette smoke," said the paper's co-author Herbert Lepor at NYU.
Dhaka, Sept 26 (UNB) - Discolouration of teeth caused by caffeine is real. A lot of people enjoy their first cup in the morning, and continue to consume coffee throughout the day. Over time, this can cause stains on teeth, which, if not removed/taken care of, could affect dental health as well, reports The Indian Express.
The stains occur when the tannins — organic substances found in plants — build up on the tooth enamel. Tannins are found in coffee, tea and even wine. In fact, black tea can cause more discolouration than coffee.
But you don’t have to give up on your love for coffee and like beverages altogether. There are some things that you can do instead to save your teeth from the stains.
This activity has to be the basic one. You cannot obviously brush your teeth every time you drink coffee. But you could begin and end your day with it. Tooth stain is basically plaque accumulation, which could be taken care of by brushing you teeth with a whitening toothpaste and visiting the dentist every now and then for regular check ups.
You must also floss regularly because brushing alone cannot remove all the bacteria in the mouth.
Use a straw
When you use a straw, less liquid touches the teeth. This, in turn, means a lesser chance for it to stain your teeth. While most people use a straw for colder beverages, you can use one for hot ones too.
Sip on water
Sip on water between cups of coffee to wash away the tannins, before they have a chance of settling on the teeth.
Adding milk to coffee makes all the difference. According to a study published in the International Journal of Dental Hygiene, casein — the main protein in milk — can latch onto tannins and prevent staining.
Chew on a gum
Chewing on a sugar-free gum does the dual task of fighting the coffee breath and cleaning your teeth at the same time. Chewing a gum increases the amount of saliva in your mouth, which, in turn, helps wash away acids and plaque.
Dhaka, Sept 26 (UNB) - A person is said to be diabetic when their blood sugar is excessively high and the insulin hormone produced in the pancreas — that breaks down the glucose — is neither made by the body nor utilised well. The condition, if not managed well, can severely damage one’s eyes, kidneys and overall health, reports The Indian Express.
According to a World Health Organization (WHO) estimate, 1.6 million deaths were directly caused by diabetes in 2016. It was the seventh-leading cause of death that year. But, it’s not all grim. The good news is that diabetes can at times be managed through a disciplined diet, regular screening and exercising.
There are several home remedies that could help you to deal with sugar level in your body along with the doctor’s prescribed medicines. One such ingredient is cinnamon, a common spice in Indian kitchen. It is used to add distant flavours to various dessert and savoury recipes. A study reported in the July 2000 edition of Agricultural Research Magazine found that consuming 1g of cinnamon per day can increase insulin sensitivity and help manage or reverse type 2 diabetes.
Benefits of having cinnamon in your diet:
* The spice is known to stimulate cells for glucose consumption.
* Consuming cinnamon promotes the release of insulin from the pancreas and boosts insulin sensitivity that helps in the processing of glucose.
* It also contains mineral chromium that keeps one’s appetite under check and helps in getting rid of visceral fat.
* Packed with essential nutrients, it makes for an excellent detox drink.
* Results from a clinical study published in the Diabetes Care journal in 2003 suggest that cassia cinnamon (cinnamon bark) improves blood glucose and cholesterol levels in people with type 2 diabetes, and may reduce risk factors associated with diabetes and cardiovascular disease.
Here’s how you can include cinnamon in your diet in a few simple ways:
Start the day with cinnamon water
Drinking warm water in the morning is a good way to start the day, To make it healthier just add a pinch of cinnamon bring to a full boil and drink the warm water. It will not just help in diabetes but also help you burn some extra fats.
A healthy substitute for sugar
Cinnamon has an inherently sweet flavour which you can use as a natural sweetener and also as a healthy alternative for refined sugar. Be it desserts like cake, pies, kheer, halwa or barfi just dust some cinnamon powder to enjoy a guilt-free dessert.
Add it to tea and coffee
Cinnamon goes well with tea and coffee, it tastes amazing too. The unique taste of cinnamon in your masala chai or hot coffee, plus its various health benefiting properties will level up your hot cup of beverage in ways more than one.
Sprinkle cinnamon powder on a bowlful of fruits and cereals taste great as is.
Saute a small cinnamon stick with other dry spices like cloves and peppercorns to make flavoursome curries.
Dhaka, Sept 24 (UNB) – World leaders have adopted a high-level United Nations political declaration on universal health coverage (UHC), the “most comprehensive set of health commitments” ever adopted at this level.
“This declaration represents a landmark for global health and development,” said Dr Tedros Adhanom Ghebreyesus, Director-General at WHO.
The WHO DG said the world has 11 years left to make good on its sustainable development goals. “Universal health coverage is the key to ensuring that happens.”
He said universal health coverage is a political choice. “World leaders have signaled their readiness to make that choice. I congratulate them.”
The declaration came on Monday, the day after the World Health Organization (WHO) and partners flagged the need to double health coverage between now and 2030 or leave up to 5 billion people unable to access healthcare, said the UN Information Center in Dhaka quoting the WHO.
In adopting the declaration, UN Member States have committed to advancing towards UHC by investing in four major areas around primary healthcare.
These include mechanisms to ensure no-one suffers financial hardship because they have had to pay for healthcare out of their own pockets and implementing high-impact health interventions to combat diseases and protect women’s and children’s health.
Besides, countries must strengthen health workforce and infrastructure and reinforce governance capacity. They will report back on their progress to the UN General Assembly in 2023.
“Now that the world has committed to health for all, it is time to get down to the hard work of turning those commitments into results,” said Melinda Gates, Co-Chair of the Bill & Melinda Gates Foundation.
“We all have a role to play. Donors and country governments need to move beyond business as usual to bolster the primary health care systems that address the vast majority of people’s needs over their lifetimes,” said Gates.
On Tuesday, WHO and 11 other multilateral organisations, which collectively channel one third of development assistance for health, launched their Global Action Plan for health and wellbeing for all.
The plan will ensure the 12 partners provide more streamlined support to countries to help deliver universal health coverage and achieve the health-related SDG targets.
Chicago, Sept 8 (Xinhua/UNB) -- Overweight adolescents, considered particularly susceptible to stress eating, actually ate less when exposed to a lab stressor, and the foods they eschewed were the high fat and sugar options, a study posted on the website of the University of Michigan (UM) on Tuesday showed.
The study, involving about 60 kids, further found that kids who produced the most cortisol after the stressor saw the biggest appetite reduction, eating about 35 percent fewer calories in the two hours after the stressor.
"These are really exciting findings because they give us a chance to observe eating patterns when adults are exposed to stress, which is a very important factor in childhood obesity, long-term cardiovascular risk and type 2 diabetes risk," said principal investigator Rebecca Hasson, associate professor of movement science at the UM School of Kinesiology.
Results were similar whether adolescents in the study were monitoring their food intake or not.
But that didn't happen among the dieters, and the results suggest that a biological response, such as the flood of cortisol or the satiety hormone leptin, drove the adolescents' reduced appetite.
"This doesn't mean stress kids out and they'll lose weight. This is in the short term only," Hasson noted. "They may eat more calories later. Typically, many kids did say they turned to food when stressed, so maybe this was a time effect."
Even if the cortisol spike didn't cause overeating, it's still metabolically unhealthy, she said. Much work remains to see who's susceptible to big cortisol spikes and the long-term effects of stress.
The study has been published in Psychosomatic Medicine.
