Chronobiology

Chronobiology investigates biological rhythms - predominantly those that correspond to environmental cycles (tidal, daily, lunar or annual). The most intensively investigated biological timing system is the circadian clock.
Behaviour, physiology, bio-chemistry, and gene expression are temporally structured over the course of a day, generating daily oscillations at all levels of life.


Cycles in attention and activity, in core body temperature and heart rate, in enzyme activity and hormone levels are not simply driven by external changes (e.g., light/dark or warm/cold).
Rather, they are controlled by an endogenous, circadian clock which are found in all phyla - from cyanobacteria to humans. Daily rhythms continue in the absence of environmental signals with their own periods that can deviate slightly from 24 h - hence the term circadian (about one day). Although circadian rhythms are endogenous and self-sustained, the ‘internal day' is regulated by external cues: circadian rhythms are synchronised (entrained) by and to the periodic environment. This ‘entrainment’ uses environmental signals (predominantly light) as 'zeitgebers'.

Over the past decades, circadian research has unravelled many details about how the circa-24-hour rhythmicity is generated at the cellular level.
Clock genes and their products form a complex network of feedback loops.
Approximately 10% of the mammalian genome shows a circadian rhythm in its expression.

The programme of the Gordon Conference on Chronobiology in 2007 covers the most recent insights into the mechanisms of circadian rhythmicity, ranging from genetics, molecular biology and neurophysiology to higher functions such as sleep and performance in shift work.
The contributions reflect the need for our field to show how these temporal programmes
function in the real world under entrainment as well as the necessity to explore clock mechanisms beyond the known transcriptional-translational feedback loops.

Because of the enormous and predictable daily changes in the metabolism of each cell, insights into circadian clocks are essential for medicine as well as for coping with the consequences of life in an industrial society that has us living indoors (i.e., providing weak zeitgebers), performing shift work and incurring jetlag.
It's a very interesting subject.
Not many of us have heared about the chronobiology. It reflects our personal, inside timer. There are some people that know how to use it and they plan their life with this method.
I'll do research about it and try to find out how we can use it so it can be helpful for us.

Miracles made by vitamins

Eating a lot of vegetables and fruits, is a great way to protect yourself from getting sick and premature death, because they contain all the vitamins your body needs. A group of scientists from the Medical and Health Institute in France, INSERM, showed recently that taking extra vitamins is also recommended for the good function of your body.

A scientific study named SU.VI. MAX, with over 13 000 participants, showed that people who
took everyday extra vitamins, they obtained a great protection against cancer with 30%, and at the same time it reduced the mortality caused by cancer with 37%.
In eight years, the participants had to take 6 mg of beta-caroten, 120 mg of vitamine C, 30 mg of vitamine E, 100 g of selenius and 20 mg of zinc- or the same tablets, placebo.
After this period, scientists showed the benefits from extra vitamins and minerals.
It was necesary to use extra vitamins, to compare them to the placebo effect. A similar test with fruits and vegetables couldn't be as useful as with multivitamins because the participants had to eat 5-6 times a day fruits/vegetables.

This was a scientific test that could only be made with extra vitamins to see how the body reacts.
Eat vegetables, and fruits, all kinds, it's very healthy. An apple everyday keeps your immune system workind at high potentional.
Have yourself a healthy life because you all deserve that!

Carrots prevent cancer and not only

Carrots can prevent the infarct. It can, also reduce lung cancer and larynx cancer, even if that person was a smoker. The most important effect of the carrot is improving the eyes. The carrot contains vitamine A wich is very important for the health of the eyes. When the quanteety of the A vitamine decreases, eyes suffer at the adaptation to the dark and to the light.
The tea with seeds of carrots, can be prepared by infusion.
In a cup of boiled water (250 ml) you put a small spoon of seeds or dry grass and you leave it for 10-15 minutes for infusion.

It's recommended do drink the tea three times a day.
The seeds help digestion and stimulate the menstruation. The seeds, as well as the leaves help eliminate gases and are usefull for the good function of the kidneys, for digestion and intestinal transit. 
If you like carrots, eat a carrot everyday and, surely, you can improve your immune system, 
your eyes and also prevent catching a cold or even getting sick. 
The A vitamine takes care of your heart, your lungs,
kidneys and of all the good function of your body.
It's a good way to start a healthy life..Good luck everyone!

New cancer treatments

New therapies against different types of cancer could appear in 10 years, studies are based on modified geanes that lead to cancer, proffesor doctor's oppinion, Victor Velculescu from Johns Hopkins University in Baltimore. Romanian scientist, descovered new medicines for breath and intestine cancer by studying the groups of cromozomes from the cancer cells.
For the first time, scientists made a map of the modified cancer cells. 
How do the modifications appear??

It seems that the cells can change by consuming different substance like nicotine, alcohol,  
exposing your skin to much at the sun radiations. If cancer is  hereditary, we have to make periodical analysis to prevent the disease and to track it down as soon as possible, and find a cure. 
The only methods used, for now, against cancer is surgery and chemotherapy.
When will new treatments appear?
For some forms of cancer like, breast cancer and leukaemia there are some medicines, but for others, scientists are still doing researches and we won't benefit of them 10 years from now. 
The problem appears when cancer isn't located and surjery cannot help in this situation, the only method remaining is chemotherapy. The last one, is not providing 100% chances of curing and some people can't endure it. I'll do some research about this technique so we can be informed with every detail about this disease and how many chances we have to survive.

Protect your body..STOP smoking!

How does smoking affect your liver..? The liver is an organe wich is very well vascularised. Everything we eat or drink goes through the liver, he's a kind of bolter. I'll show you some pictures I found with sick livers.


                            Liver cancer                                               

  Chemotherapy at the liver

I know there are some scary images but this is the truth! Even if this can shock you...it's better to be aware of the consequences if you keep on smoking. Around the world take part a lot of campaigns against smoking but, I guess it's not enough because, so many people are still smoking and also, many people are still dieing because of this bad habit and drug. Protect your children from places where others are smoking, teach your children, especially teenagers about cigarettes, smoking, drugs and the power they have to destroy our body. We have to do something for the humanity..it's sad seeing so many children, adults and old people dieing..
Have the courage and the strength to heal yourself and accept that you are doing a lot of damage to your mind and body by smoking. I wish you good luck and I'll sure keep you healthy informed!

Stop smoking!

The number of people who smoke is growing. In the world there are 1.2 bilion smokers. Even though, people living in 2004-2005 know enough about smoking, causes, how to quit and still, are not aware of how tobacco destroys our body.
In nowadays, everyone talks and writes about this subject, bad habit that changed the entire humanity for centuries. This subject has always been a matter in dispute. Smokers that wanna quit can find all the info about cigarettes on TV, in magazines and newspapers, in flyers and at special counciling to quit smoking.
Why do teenagers start smoking??
Well, because of the period they go through and the transformations of their personality at this age, the environment and their friends who influence them.
You can't start a conversation with a teenager, about smoking without knowing the reason he started doing it.
There are several reasons, like trying to be mature, act like a grown-up, being more self confident and being part of a gang. Of course, teenagers smoke because of the problems they have with their parents or/and at school.
Do we smoke because we like to, beause we need to or we can't quit because it becomes a habit?
Most of the people who smoke, they do it because they like to and also, they made it a bad habit. In my oppinion, the body doesn't need cigarettes to survive, so...I guess smoking is just an action some people are used to do, like dressing some kind of clothes or drinkig coffee.
All the actions we make come from the brain. Our body doesn't need anything and can live
without any substance that doesn't help it's natural function.
How can we STOP smoking? How can we say NO to cigarettes?
It's not easy but it's not so hard, it just takes some responsability to realise how the tobacco destroys our body, how it affects our lungs, our liver and the entire good function of the body.
I've also been smoking for an year 'til I had some problems with my  thyroid (gland). I went to the doctor and he told me I had to quit smoking if I wanna live longer.
Than I had to choose, and I chosed LIFE, even if I'm young, I don't wanna destroy my health because someday I'll need it and I won't have it anymore. Nothing is more important in this life then being healthy, because you can't do anything if you don't feel well and if you don't have the power to do all the things you dreamed of.

My advice for all you out there who are smoking and for the others who haven't started yet, you just don't appreciate your health until it's gone. And maybe when you'll realise that, it's going to be to late. Please do have a healthy life!

Your skin can be in danger

A terrible infection, most seen in hospitals, appeared outside the hospital rooms. S. aureus is a staphylococcus that rezists at antibiotics and it is spreding very fast.
It produces an iritation of the skin, wich, if it's not treated it can cause big infections and also, death. Scientists from California University, Los Angeles, descovered that 59% of the skin infections from 11 hospitals were produced by MRSA.  
The author of that studies this disease, dr. Gregory Moran, sais that:,, Everyone can be infected. If you have a pimple or a furuncle that doesn't heal, go to the doctor."
