“Your behavior is not the result of your ability, but the state of mind that you are in at this moment.” This means that without the resourceful state of mind, it is almost impossible to do what you want to despite your will, skill, logic, knowledge and intelligence. Hence it becomes important to know how to create the state of mind in order to live life as you want. For understanding this in a proper way, we must understand the basic structure of our life based of Body, Brain and Mind.
The human body is like a huge super system made up of several intricate systems, which in turn may be made up of many subsystems. One of the major systems is nervous system. It is a vast network containing billions of neutron cells. These cells collect, process, distribute and utilize all the information that is used by the body to function. This system is divided into two parts – the central and the peripheral.
The central nervous system consists of brain and spinal cord. It receives all information coming in from the body systems, processes it and issues instructions to those systems. The other system, i.e. peripheral nervous system carries information signals to and from central nervous system and the rest of the body and vice versa.
The human brain is considered to be the most complex structure in the universe. Brain of an adult weighs around 1.4kg. it is believed that when brain’s 100 billion cells are fully at work, they consume up to 20% of the body’s oxygen. Majority of brains content is water.
Human brain is organized into various ‘departments’ which control functioning of different parts of the body. This is done through two types of cells-neurons called glial cells. The neurons are information carriers. And each neuron is connected with thousands of other neurons. They transmit the information from and to brain very very fast. The other cells (glial) offer supportive environment to the neurons.

The Essential Grocery List:
There are certain foods you need to have right at the top of your grocery list. Not only are they nutritious but delicious too.
Whether you’re tossing them into a salad or eating them by the handful-these nuts are an excellent source of monounsaturated fat. There are also an excellent source of protein, vitamins (such as thiamin, riboflavin, and E) and minerals (think: copper, iron and zinc).
Not only is this vegetable packed with anti-inflammatory nutrients, it contains high levels of folic acid – which can assist in the regulation of your moods by releasing a neurotransmitter called “serotonin” into your system. But if the feel good powers of asparagus aren’t enough to sway you, maybe be its anti-cancer benefits will. Research published in the International Journal Cancer Letters suggests that the consumption may halt the formation of cancerous tumors.
These super fruits packed with heart-healthy monounsaturated fats and are excellent carriers for the fat-soluble vitamins A,D,E and K. Research has not only linked avocado consumption to improved cardiovascular health but also blood sugar regulations.
Whether you’re eating black berries loaded with antioxidants that improve brain functioning, or blueberries packed with vision-protecting vitamin C, it’s hard to go wrong by adding one of these super foods to your diet. But if the high vitamin an antioxidant intake isn’t appealing enough, research published in the Journal of Medicinal Food found that berries (specifically strawberries, raspberries and blueberries) have properties that can help lower your risk of breast and cervical cancer.
In terms of conventional nutrients, peppers are packed with antioxidants (specifically vitamins A, C and E). And according to research from the University of Illinois, consuming bell peppers can assist the body in neutralizing free radicals, educing your risk of disease.
Nutrient-packed and cheap? That’s the one-two punch offered by these legumes. In fact, according to research from the University of Guelph in Ontario, black bean have similar heart healthy cancer – preventing compounds typically found in berries, tea and red wine.
This cruciferous vegetable is not only high in vitamins C and K; it’s staked with the photochemical indoles and sulforaphane, which many consider to be anti-cancerous nutrients. But the benefits of broccoli aren’t limited to cancer. A research suggests that it has the ability for protecting cardiovascular health.
This cruciferous vegetable is packed with essential nutrients for your body (think Vitamins A, B6, C,E and K) as well as selenium, a mineral that helps the body battle free radicals. Numerous studies have also pointed to its potential for preventing cancer of the bladder, breast, colon and lung.
Squash is low in calories and high in vitamin C. But more importantly, it’s loaded with beta- carotene and beta-cryptoxanthin, which are powerful anti-oxidants.

The Prostate Gland
The prostate gland is a doughnut – shaped cluster of glands located at the bottom of the bladder about halfway between the rectum and the base of the male reproductive organ. Its main function is to store and produce seminal fluid, a milky liquid that transports and nourished sperm. It requires male hormones, like testosterone, to function properly, helping to regulate bladder control and normal sexual functioning.
Problems with the Prostate
- Prostatitis inflammation of the prostate gland. It is often the result of infectious bacteria that invades the prostate from another area of the body. It can affect men in their late teens to those well into old age. The condition is not contagious and cannot be transmitted sexually to a partner, Its symptoms include:
- Trouble passing urine
- Chills and fever, and
- Sexual problems
- Enlarged Prostate: As a man ages, the prostate can grow larger. At age 40. The gland might have increased from the size of a walnut to that of an apricot. By the time he reaches the age of 60, it might be the size of a lemon. This is a non-cancerous growth of the prostate that can interfere with urination. Symptoms include:
- Urgent need to urinate
- Weak urinary steam,
- Frequent urination
- Prostate Cancer: Prostate cancer grows slowly and may not spread for many year, but a medical examination can help prevent it. Symptoms include:
- Difficulty starting urine flow
- Pain during urination
- Loss of weight and appetite
- Blood in urine
- Digital rectal examination: A DRE can sometimes detect an enlarged prostate, lumps or nodules of prostate cancer, or tenderness from prostatitis.
- Prostate – specific antigen (PSA): the prostate makes a protein called PSA, which can be measured by a blood test. If PSA is high, prostate cancer is more likely, but an enlarged prostate can also cause a high PSA.
- Prostate Ultrasound: An ultrasound probe is inserted into the rectum, brining it close to the prostate. Ultrasound is often done with a operation to test for prostate cancer.
- Prostate biopsy: A needle is inserted into the prostate to take tissue out to check for prostate cancer.

Some of the most devastating forms of cancer have genetic similarities even though they strike different body parts, according to new studies out on Thursday.
The new research – one study focused on a form of leukemia, in the New England Journal of Medicine, and a second on endometrial cancer, in Nature – could offer a pathway to new more effective treatments.
The new findings challenge the previous approach of classifying tumors based o the body part where they are first observed, and add fuel to the growing trend of differentiating tumors based on their genetic profile.
The research came as part of a vast program undertaken by the National Institution of Health called “Cancer Genome Atlas Project,” which aims to decode the genetic pattern of 10,000 tumors from 20 different cancers.
Thanks to that analysis, scientists had already found genetic relationships between certain forms of breast, lung and colon cancers.
For example, one type of breast cancer presents genetic mutations very similar to the ones found in ovarian cancer, and colon cancers often have mutations found in breast cancer. The researchers said around half of all lung cancers could respond to treatments used against other kinds of tumors.
The latest study found the most aggressive form of endometrial cancer, which affects the uterine lining, is similar to more grave forms of breast and ovarian cancer.
“The clinical and pathological features of uterine serous carcinoma and high-grade serous ovarian carcinoma, or HGSOC, are quite similar,” wrote the authors of the study published in Nature, which analyzed more than 370 tumors. Likewise, “HGSOC hares many similar molecular features with basal-like breast carcinoma,” added the team, which was directed by Douglas Levine of Memorial Sloan Kettering Cancer Center, in New York.
Researchers have also determined that a certain mutation, already identified in other tumors, is more common in relatively understudied uterine tumors than in any other cancer under analysis by the genome project. Several drugs have already been developed to target the mutation. Now, thanks to the new data, such drugs can be harnessed against endometrial cancer, which kills 8,000 people, and is diagnosed in 50,000 each year. The research on acute leukemia, while included 200 patients, identified at least 260 genetic mutations implicated in the blood cancer, but wasn’t able to detect any that are systematically found in most serious forms of the disease.
