Pacemaker or artificial pacemaker, its not heart's natural pacemaker. It is a medical device that uses electrical impulses, delivered by electrodes contacting the heart muscles, to keep the normal beating of the heart. The primary function of a pacemaker is to maintain an adequate heart rate, if there natural pacemaker of hearts is not fast enough, or there is a heart block. A group of Scientists of Seder- Sinai Heart Institute have got a success. Human heart is made of millions of cell. But among them only 10 thousand cell contribute to pacemaker and make heart beats. For aging or other heart diseases when heart rate become high or low then electronic pacemaker is used to keep it normal.. But using this electronic device there remain some complications to risk. For consideration to low the risk scientists have used genetic recombination by replacing T BX-18 gene via a virus to cells of the heart, which can make normal heart rate in its own heart.....
Are you concious about Oral Cancer....!!!!!
Oral Cancer
Oral cancer in medical term most commonly recognized as oral carcinoma. In Asian countries like India, Sri Lanka and Bangladesh cancer of the mouth accounts for approximately 40% or more. And it also accounts for only about 25 of all malignant tumours in such countries as the UK and the USA. Over 70% of oral cancers arised from on the lateral borders of the tongue and asjacent alveolar region and floor of the mouth. 95% cases are well or moderately well-differentiated squamous cell carcinoma.
Oral cancer is a age-related disease and more frequenty seen in those aged 30-50.
Probable Causes are Tobacco chewing, alcohol consumption, betel quid habit.
Infections like Shyphilis, Candidosis and other viral infections are sometimes responsible.
Other mucosal dieseases like Oral epithelial dysplasia, Lichen planus, Oral submucous fibrosis can cause oral cancer.
Clinical features
In earky stage it appears as white or red paches or ulcers, sometimes may be painless or sligthly sore. later it become large and painful. It may spreads by diresct invasion by surrounding tissue and by lymphatic metastasis. The submandibular and jugolodigastric lymphnode are most commonly involved.
Investigation
Investigation is done by Biopsy
Imaging for oral cavity cancers and FNAC
Treatment
In practice most cases are trested by surgery combined wuth radiotherapy. surgery alone is preffered for small carcinomas of the tongue thet may be easily excised. And if it involed bones then it depend upon surrounding region. Sometimes partial mandibulectomy( removal of a part of mandible) or hemi-mandibulectomy(removal of half portion of lower jaw in figure) is done. Partial parts of removed jaw is retained by re-construction plate(Radiographic figure).
How to Overcome Sciatica
How to Overcome Sciatica
Sciatica is a disorder characterized by low back pain combined
with a pain through the buttock and down one leg. It occurs when there is any damage
or compression of the sciatic nerve, a huge nerve that runs from the lower back
down the back of each leg.
 |
| Nerve Comes From Scarum |
The Sciatic nerve controls
muscles in the back of your knee and lower leg and delivers feeling to the back
of your thigh, part of your lower leg and the sole of your foot. You will feel discomfort,
faintness, coldness or burning sensation in those parts of the body when you
have sciatica.
 |
| Disc Prolapse |
The most common reason of
sciatica is a herniated disk. Natural wear and tear of the vertebrae can lead
to a tapering of the spinal canal. This narrowing, called spinal stenosis, may
put compression on the roots of the sciatic nerve and may yield symptoms. In
rare cases, sciatica may result from lumps growing inside or along the vertebral
cord or sciatic nerve, septicity or injury to nerve due to fracture of bone.

| Sciatic Nerve Pain Region |
There are stages you can proceeds
at home to comfort the pain of sciatica. A warming pad or ice pack may be specifically
supportive. Although bed rest is not suggested, decrease your activity for the
first pair of days. Then, slowly start your usual events after that. Avoid weight
lifting or twisting of your back for the first 6 weeks after the pain begins.
You should start routine exercising again after 2-3 weeks. A physiotherapist
can show you how to gently stretch the hamstring and lower back. Depending on
your medical condition, certain exercises may not be recommended.
Over-the-counter pain relievers can deliver short-term relief from sciatica.
Injections, surgery may be needed in definite cases.
If you have had sciatica once,
there is a coincidence that it will reappear. But there are steps you can take
to reduce the odds:
* Exercise regularly.
* Maintain good posture.
* Bend at the knees to lift
heavy objects.
Now the pain of Insulin taking may be reduce…
Now may be the taking of Insulin drug can end. By the combined research of both USA and Australia it reveals. Accompanied scientists have told that they are trying to release most of the diabetes patients from daily painful insertion of Insulin injection to body.
Insulin which is a hormone release from Pancreas and addition with superficial surface of cells of human body and help to preserve carbohydrate or glucose. Then glucose transformed into energy to human body. For the first time scientists has discovered the three-dimensional view of insulin bound to its receptor. In the last edition of ‘Nature’ magazine the research was published. Previously, scientists were unsure about how insulin binds to the
receptor on the surface of cells to allow them to take up sugar from the
blood and generate energy.
Now the scientists have the clear knowledge about the absorption of insulin in surface of cell.
Scientist Mike Lawrence of Walter and Eliza Hall Medical Research Institute in Melbourne,
has told that they are trying to discover new and active treatment
method for diabetes and they are doing researches for a long time often
20 years. They got the idea of molecular reaction between the human body
cell and insulin hormone by powerful rays like X-rays. Treatment of
diseases like Alzheimer and cancer caused by Insulin disorder can be
progressed.
Mike Lawrence also said, “ For the developing country it is need to
discover new and long duration active Insulin which does not require
refrigeration.”
Taking long time Aspirin may be harmful for eyes………………………….
Scientists have told that taking a long time Aspirin may be harmful for your eyes. Recently in a research has shown that taking Aspirin for 10 years or more can bring harm to eyes.
Research report has been published recently in ‘Journal of the American Medical Association’.
Researchers told that taking Aspirin therapy for a long period may decrease your visual power with age.
The report has shown that often 19% people of U.S.A take Aspirin regularly for reduce pain, treatment of arthritis and in case of heart diseases. In that research is 5000 people are include whose age is between 43 to 86 years. Researching two decade every 5 years interval scientists had examined the eyes of patients taking Aspirin. In examination it is discovered that eye diseases has found in those patient who is taking Aspirin for 10 years or more.
Researcher Barbara Klein said,”Aspirin is taken by people for its usefulness but why it brings harms for taking it regularly is a question of fact. It requires huge researches.”
Nose, entrance of external respiration

| Nose, entrance of external respiration |
Here its lining epithelium is condensed and squamous and has strong hair follicle.
Internal cavity is known nasal cavity which is separated into right and left side by a thin wall. Lining epithelium of the cavity is siliated, contains mucous membrane and blood vessels and nerve supply. Upper part of the nasal cavity is lined by mucous membrane that contains nerve cell of Olfactory (Central nervous system).

Screening of Breast Cancer
Breast cancer is number one cancer problem in
world wide. If this cancer is detected in primary stage then the rate of death
can be decrease. In primary stage the
cancer can be detected by a method named ‘Breast cancer screening’. By
examining breasts searching of sign of cancer when any disorder or sign is not
present in breast. Maximum time successful treatment is done by not surgical
removal of breast.
Body weight is normal, habit of regular
exercise or workout.
Breast feeding of baby for 18 months or
more.
Breast
Self examination (B.S.C)
Ultrasonography, MRI and if necessary then
F.N.A.C (Fine Needle Aspiration) that is aspiration of fluid from affected side by
needling and microscopic examination.
What is Mammography??
Mammography is an X-ray method of breast examination.
Especial type of machine is used in it. In case of using X-ray, radiation is a
harmful ingredient of causing breast cancer. But in Mammography a little amount
of radiation is used. After 50 years age, in interval of 2-3 years if there
done screening, mammography and in primary stage the disease is detected then
the benefit is more than harm.So, Mammography is the strongest media. Under
specialized radiologist, female radiology technologist operate mammography
machine and give the reports. Generally after 50 year mammography should be
taken and if health condition is well then continue it for 70 year in 3 year
interval. In developed country, different committee held this type of
conference for a long time. Some of them advised to do screening mammography
for 47 to 73 years old. In case of highly risked women it is suggested after
40. Under 30 it is not applicable because in younger women the mammary glands
are so concentrated. So if any mammography is done then the image can be hidden
under these
For which women screening is needed??
A woman by born is in risk of breast cancer. But
all women are not in same risk. Generally there is no risk before 20 year old.
The risk of cancer begin being old. When age is near to the 50 then risks is
increased. In case of both highly risked and low risked women the screening
test should be done by considering some risk factor.
But in case of highly risked women the screening
test should be done from early age and every year.
Low risked women
Woman who has no sign and symptoms of
cancer.
In whom family background is absent like
mother, sisters of mother, grandmother, daughters have not affected by cancer.
Or any member of family has no history of cancer like ovary cancer or colon
cancer.
Body weight is normal, habit of regular
exercise or workout.
Breast feeding of baby for 18 months or
more.
High risked women
·
If any one of female family member or
relative are affected by breast cancer especially history of more than one of
relative. Also history of other cancer.
·
Previous record of breast cancer or
primary stage of it were detected in past.
·
If there is excess number of mammary
gland (Breast is consist of mammary gland).
·
Excess fat, weight and avoidance of hard
working.
·
If period or menstrual cycle occur in
early age and Menopause occur in late age.
·
Avoidance of breast feeding of baby.
· Taking of O.C.P for a long time or Hormone therapy after Menopause.
· Taking of O.C.P for a long time or Hormone therapy after Menopause.
What are tests done in screening???
Breast
Self examination (B.S.C)
It is done by examination of breasts by self and start it
from age of 20 year in every month. And continue it for whole lifetime.The aim
of this examination is to detect any abnormality of breast and take appropriate
treatment for it. Abnormalities like feeling of any mass in breast, thickness
of skin of breast, secretion of any liquid or blood from nipples.
Clinical Breast examination (CBC)
The method is clinical examination of breasts by
trained doctors. One examination is done in 3 years at age of 20-39 year and
every year after 40 age of year. Beside this, Doctors advice to do other
examinations.
Mammography and other radiology and imaging examinations
Ultrasonography, MRI and if necessary then
F.N.A.C (Fine Needle Aspiration) that is aspiration of fluid from affected side by
needling and microscopic examination. What is Mammography??Ladies fast in using emoticons...
In mobile, sending S.M.S or massages, ladies use emoticons more than men. But in case of using various emoticons men are first. Recently in a survey it is discovered.
Using different letters and sign we use emoticons. These are used to express our different condition and mood. We use it usually in chatting or S.M.S.
In America, researchers of Rise University of Texas gave a Smart phone in free of cost to every man and woman. But they didn’t tell the people about the research. Then total 10 million and 24 thousand S.M.S are researched. In this case, observed that all of them use emoticons but not in same way. They used it 4% in total sending S.M.S. And ladies are using double emoticons than men. The result of this research has published in 'Computer in Human Behavior Magazine'. ;)
DNA Test within 50 Hours of Infant
There may be a hope for treatment of new born baby with genetic disorder. The American researcher told that we can do the DNA test of severely diseased infants within 50 hours.
By this Doctors can take a quickly measurement to diagnose the disease. In past, it took a month to done it.
Gene controls the hereditary characteristic and this gene is the part of DNA. Protein which is the main raw material for our body building is mainly produce from DNA.
A new method for DNA test, exclusively apply by researcher of ‘Children Mercy Hospital’ in Kansas city of America.
Stefen Kingsmor has mainly leads the research. They released the news in medicine related magazine ‘Science Transitional Medicine’.
Scientists research with genome by blood of 5 infants. Among them there are two brothers. They all are involved by unknown disorder. Researcher found same type of changes in genome and also done the DNA test of their parents. They found completely newly formed changes in genome. And other problems gain from their parents.

Concentration gain by seeing animal kids…
There is good news for peoples who pay full concentration to their work. A new method is discovered to pay more concentration in your work.
Attractive picture of animal especially kids of animal is used to accelerate your speed of activity. Researcher told that by this way, we can increase capability of working of peoples. And this method is time consuming.
The researchers of Hiroshima university of Japan are recently report this. By a headline named “The power of cow eye” they published the information in ‘Plos One’ online magazine of America.
Happiness, fun and cheering helps to progress our activity and speed.
By considering this thinking, researcher done this among 130 number of college going students. Students are divided into three groups. Among them the pictures of puppy and kitty are shown one group. And to other two groups, there shown animals and tasty foods.
After surveying researcher found that the group who sees the tasty foods has no progress and the group who sees animals are progress is 5%.
But the group woo sees kitty and puppy, their progress is 10%.....
