Cholesterol ‘fuels’ breast cancer

According news in BBC, based on group of scientist research , a by-product of cholesterol can fuel the deadly growth and spread of breast cancer.

According to them, It raises the prospect that taking cholesterol-lowering drugs called statins could prevent cancer. The work, published in the journal Science, helps explain why obesity is a major risk factor for the disease. However, cancer charities cautioned that it was too soon to advise women to take statins.

Thus, obesity has been linked with many cancers including those of the breast, bowel and womb. The fat in overweight people can pump out hormones, such as oestrogen, which drive the growth of cancers.

The researcher says as a treatment in to this issue, their findings raise the prospect that lowering cholesterol can lower the risk of breast cancer developing. A healthier diet is another way to cut levels of cholesterol in the bloodstream.

Dr Hannah Bridges, from leading charity Breakthrough Breast Cancer, says: “Up until now research into the links between cholesterol levels, use of statins and breast cancer risk has been inconclusive.

“The results from this early study are promising and if confirmed through further research could increase our understanding of what causes some breast cancers to develop.”

“As things stand, until we know more about the effects of statins on cancer risk, the best ways to cut the risk of developing breast cancer are to stay a healthy weight, cut down on alcohol and keep active.”

Menopause and sexual

A woman’s production of sex hormones, in particular oestrogen, falls significantly around menopause. Her testosterone levels will have declined slowly since she was about 20 years of age. A woman in her forties has, on average, half the testosterone circulating in her bloodstream that a woman in her twenties has. The reduction of these hormones may directly affect libido or sex drive and sexual function in some women. Menopause may also cause physical and psychological changes that will affect sexual function.

Menopause, the final menstrual period, occurs when a woman stops ovulating and her monthly period (menstruation) ceases, marking the end of her reproductive years. Menopause can affect a woman’s sex drive or libido. Contraception, physical changes such as a dry, painful vagina, body image, hormone changes, relationships and social issues may also affect sexuality and libido.

However, Pregnancy is possible, though rare, before and even after your last period. It is generally advised that menopausal women should use contraception until at least one year after their natural periods have ceased. This is because a pregnancy late in a woman’s reproductive life increases the risk of birth defects for the child and health problems for the mother.

Both during and after menopause, a woman may notice certain physical changes that affect her sexuality in positive and negative ways. These may include a woman’s vagina and bladder become more susceptible to bacterial infections,  a woman who was troubled by heavy or painful periods may feel relieved and positive about her change of life. This can lead to a renewed interest in sex and  can include hot flushes, night sweats, insomnia and unusual skin sensations like prickling or itching.

Important factors influence a woman’s sexual desire at menopause, including contraception, body image, hormone changes and relationships. Seek advice from a professional if you need help with any sexual problem.

Breathing and stress

Breathing is an automatic function of the body that is controlled by the respiratory centre of the brain. When we feel stressed, our breathing rate and pattern changes as part of the ‘fight-or-flight response’. Many people use their breathing to help promote relaxation and reduce stress. The types of conditions that controlled breathing might help include asthma, anxiety, high blood pressure, and stress.

When a person is under stress, their breathing pattern changes. Typically, an anxious person takes small, shallow breaths, using their shoulders rather than their diaphragm to move air in and out of their lungs. This style of breathing disrupts the balance of gases in the body.

When a person is relaxed, they breathe through their nose in a slow, even and gentle way. Deliberately copying a relaxed breathing pattern seems to calm the nervous system that controls the body’s involuntary functions.

There are different breathing techniques to bring about relaxation. In essence, the general aim is to shift from upper chest breathing to abdominal breathing. You will need a quiet, relaxed environment where you won’t be disturbed for 10 to 20 minutes. Set an alarm if you don’t want to lose track of time.

Sit comfortably and raise your ribcage to expand your chest. Place one hand on your chest and the other on your abdomen. Take notice of how your upper chest and abdomen are moving while you breath. Concentrate on your breath and try to gently breathe in and out through the nose. Your upper chest and stomach should be still, allowing the diaphragm to work more efficiently with your abdomen rather than your chest.

 The stress response can be reduced by consciously breathing using the diaphragm. Abdominal breathing helps to control the nervous system and encourages the body to relax, bringing about a range of health benefits.

Malaysians from eating their way to health problems

Based on the news published in News Straits Times, WHILE awareness about health has improved over the years, it has not stopped Malaysians from eating their way to  health problems.

According to the interview source of Prince Court Medical Centre chief executive officer Dr Chong Su-Lin, said,” Malaysians are eating way too much”.

“Food is available 24 hours and people eat burgers or nasi lemak at odd hours,” she said.

She added that such eating behaviour would lead to obesity, diabetes and kidney-related diseases.

It was reported that Malaysia had the most number of fat or obesity people and diabetics in Southeast Asia.

Dr.Choong said, “nowadays, parents work long hours and they don’t keep an eye on what their children are eating.”

She said children often bought candy or drinks with high sugar content after school.

A big health issue related to the burgeoning obesity in the country is diabetes.

The NHMS 2011 highlighted an alarming figure, that one in five over 30 is a diabetic.

“The thing with diabetes is there are no symptoms. By the time a person realised he has it, it’s too late.” And also plan your diet and exercise,” she said, adding that it was important to eat meals on time. It was better to eat at home rather than eating out.

“Eating at home enables you to control your salt, sugar and oil intake.

Mars Orbit Mission in India

   Recently, India announce the countdown for start they first ever mission to planet by their own  ISRO’s Mars Orbiter Mission (also called ‘Mangalyaan’), was launched on November 5, 2013. They said, Mangalyaan journey wont be an easy one event though still 300 days away from Mars. Thus, not all country been succeed in Mars mission, whatever it is, Indian space industry has much to learn from the Mars Orbiter Mission. There are some tips given by them to be able to track Mangalyaan’s progress over the next year.

Map the ride

The apogee has so far been boosted to over 1 lakh kilometers. The final midnight manoeuvre scheduled for November 30 will have the spacecraft boosted to an apogee of about two lakh kilometres. By now, the spacecraft would have attained a velocity high enough for it to be catapulted out of the Earth-bound orbit and into a sun-centric orbit.

SECOND, Mangalyaan’s goal now is to attain orbit around Mars using minimum fuel. The most efficient way to do this is to take a 690-million km trip in a sun-centric orbit to finally reach Mars orbit in September next year. That is a 300-day journey!

THIRD, Mangalyaan is reoriented into a Martian orbit by slowing it down and firing its engines. This is scheduled to happen on September 24, 2014 at 17:21 hrs. This process involves so many complex steps and timing, that even the smallest mistake can have the orbiter vanish into space.

Fully packed

Mars Colour Camera (MCC) will provide images of the Martian surface, and will be used to monitor the weather as well as for probing Mars’s satellites.

Mars Exospheric Neutral Composition Analyser (MENCA) will study the composition of the Martian upper atmosphere.

Why some missions failed

Faulty software: Bad mathematics may not kill you, but they can kill spacecraft! NASA’s Mars Climate Orbiter (1998) disintegrated because at one instance, its software used the wrong units (pounds, instead of Newtons). This caused the spacecraft to be placed too close to Mars where atmospheric stresses destroyed it.

Solar flares and fuel shortage: The communication systems of Japan’s Nozomi orbiter (1998) were disrupted by powerful solar flares. It also damaged the heat control system causing the fuel to freeze. It was unable to attain Mars orbit and operation was terminated.
