During the whole duration of pregnancy, from the first week to the last, it’s important to take good care of yourself in order to maintain good health of your baby at the time of delivery. Even though, if you have gathered enough knowledge about pregnancy stages, you have to take some precautions and be ever-aware of how what you are going to do and does it cause any harm to your baby. Many women say they’ve never felt healthier than when they carried their children.

In the early days of prenatal care, you may get initial pregnancy signs such as morning sickness, nausea and tiredness. Your body will change internally as well as externally as your baby grows during the nine months of your pregnancy. In this time you need some extra calories from quality nutrition and some thongs to avoid which could affect your baby.

New findings suggest that the brains of older women perceive upsetting images in different way than young women. It’s a clear indication that the human brain, with the passage of time, learn to handle the bitter experiences of life.

“Older adults are able to show a less reaction to negative emotions,” said Roberto Cabeza, psychologist of Duke University.

Researchers have thought that the older people deal with emotions differently or less reactively than the young, Cabeza said. “Reports have provided us with the fact that there’s a shift in the bias, perhaps a reduction of negative emotions and stress on processing positive emotions,” he said.

For the execution of the theory about brain, Cabeza and his colleagues isolate 15 young of average age 25 and 15 older healthy women with average age 70.

The women were shown pictures chosen to draw positive, neutral and negative responses. In next step, the women were tested to reveal which photos they remembered. The fMRI technology was also implemented to measure neural activity.

Though both groups of women remembered negative images, the older ones memorized lesser than the young women, Cabeza said. Less activity between different neural areas has been examined in the brains of old women.

Smoking is associated with various cancers and now there is another addition, as Italian researchers say that smokers have a higher risk of becoming the victim of colorectal cancer.

The study, published in the l Journal of the American Medical Association. 17 Dec. issue, reveals that smokers have almost 18% higher risk of getting that cancer and 25% increased risk of death from the disease.

Edoardo Botteri, the lead author of the study, says: “There is a significant link between smoking and the occurrence of colorectal cancer and related deaths.”

“Smokers must keep in mind that it not only increases their risk of developing the cancers of the organs that have direct tobacco exposure including lungs, larynx and digestive tract of upper area, but it also increases the risk of developing cancers in those organs that don’t have a direct tobacco contact like kidney, bladder, pancreas, rectum and colon,” he added.

Drug abuse can be defined as, “harmful use of any drug or alcohol for mood-altering purposes.” Another definition is “the use of illicit drugs or the abuse of prescription drug for purposes other than those for which they are recommended or the use of excessive dosage than prescribed.”

There are number of ways through which drugs can be administered such as sniffing, through injection trough skin and even through eyes. In brain enormous neurons are connected through synapses. In synapses chemo transmitters are transmitted from one neuron to other so they conduct impulse this way and aware human brain about position, fear and brain made the action in accordance with the situation.
