Science Discussion Forum / LSISK EYE SURGERY: ADVANTAGES
« on: March 08, 2015, 09:38:58 AM »
          What Are the Advantages of LASIK Eye Surgery?

LASIK has many benefits, including:

•   It works! It corrects vision. Around 96% of patients will have their desired vision after LASIK.

•   LASIK is associated with very little pain due to the numbing drops that are used.

•   Vision is corrected nearly immediately or by the day after LASIK.

•   No bandages or stitches are required after LASIK.

•   Adjustments can be made years after LASIK to further correct vision if vision changes while we age.

•   After having LASIK, most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.

Science Discussion Forum / WHAT IS LASIK
« on: March 08, 2015, 09:33:21 AM »

 LASIK stands for laser in-situ keratomileusi. It is a popular surgery used to correct vision in people who are nearsighted,farsighted, or have astigmatism.

All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye.

LASIK is one of a number of different surgical techniques used to reshape the cornea


1. We should make a to-do list and carry with us all the time

 2. At the end of our day, should review what we have done and make a new list for the next day

 3. We should learn to differentiate between the important and the urgent. What’s important is not always urgent. What’s urgent is not always important.

 4. All things being equal, we should do the simplest and reduce the to-do list

 5. If a task takes less than five minutes, we should do it right away. If it takes longer, put it on the list.

 6. We should schedule some uninterrupted time each day when weu can concentrate on important tasks

Allied Health Science / Alpha waves and deep relaxation
« on: February 26, 2014, 11:43:14 AM »

This reduction in stress hormones may be explained by the relaxed state that comes about through meditation. Electroencephalograph (EEG) studies of the brain in those who are meditating show that meditation boosts the intensity of alpha waves – associated with quiet, receptive states — to levels not seen even during sleep. This relaxed state combats anxiety, and this is confirmed by research which has found lowered levels of lactic acid in the blood. (High levels of lactic acid are associated with anxiety.)

There are five frequencies produced in our brain, (Beta, Alpha, Theta, Delta and Gamma), and each frequency is measured in cycles per second (Hz) and has its own set of characteristics representing a specific level of brain activity and a unique state of consciousness



Two very quick and easy meditation techniques. The great thing about these techniques is that they can be done anywhere.

1  Belly Breathing
This technique is designed to relax the body by teaching  how to breathe as deeply as possible. Even a few short minutes of this technique can help relax tremendously.

2. Counting the Breath
This technique involves giving each breath — both inhalation and exhalation — a specific count. It is terrific for focusing the mind and increasing relaxation.

Science Discussion Forum / WHY MRI IS DONE?
« on: February 25, 2014, 10:09:24 AM »

Magnetic resonance imaging (MRI) is done for many reasons.

It is used to find problems such as tumors, bleeding, injury, blood vessel diseases, or infection. MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan. Contrast material may be used during MRI to show abnormal tissue more clearly. An MRI scan can be done for the:

Head. MRI can look at the brain for tumors, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by a stroke. MRI can also find problems of the eyes and optic nerves, and the ears and auditory nerves.

Chest. MRI of the chest can look at the heart, the valves, and coronary blood vessels. It can show if the heart or lungs are damaged. MRI of the chest may also be used to look for breast or lung cancer.
Blood vessels. Using MRI to look at blood vessels and the flow of blood through them is called magnetic resonance angiography (MRA). It can find problems of the arteries and veins, such as an aneurysm, a blocked blood vessel, or the torn lining of a blood vessel (dissection). Sometimes contrast material is used to see the blood vessels more clearly.

Abdomen and pelvis. MRI can find problems in the organs and structures in the belly, such as the liver, gallbladder, pancreas, kidneys, and bladder. It is used to find tumors, bleeding, infection, and blockage. In women, it can look at the uterus and ovaries.

Bones and joints. MRI can check for problems of the bones and joints, such as arthritis, problems with the temporomandibular joint, bone marrow problems, bone tumors, cartilage problems, torn ligaments or tendons, or infection. MRI may also be used to tell if a bone is broken when X-ray results are not clear.

MRI is done more commonly than other tests to check for some bone and joint problems.
Spine. MRI can check the discs and nerves of the spine for conditions such as spinal stenosis, disc bulges, and spinal tumors.

Science Discussion Forum / What is MRI?
« on: February 25, 2014, 10:07:47 AM »
Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. MRI also may show problems that cannot be seen with other imaging methods.

For an MRI test, the area of the body being studied is placed inside a special machine that contains a strong magnet. Pictures from an MRI scan are digital images that can be saved and stored on a computer for more study. The images also can be reviewed remotely, such as in a clinic or an operating room. In some cases, contrast material may be used during the MRI scan to show certain structures more clearly.

NOW YOU WILL BELIEVE  that it is possible to get ELECTRICITY FROM FRUITS. Plz see the link

Allied Health Science / Open Type of MRI is now available in Bangladesh
« on: February 25, 2014, 09:58:42 AM »
People are scared of doing MRI as it puts you in a drawer and the closes it for around 30 minutes to take the reading for the soft tissues in the body. Now CMH has imported the open type MRI system which is nothing to get scared of. You simply lie down in bed and they will take the readings for u. Before doing MRI for old or children was a tuff job. They had to be unconcious to get the reading.

Common Forum/Request/Suggestions / PLEASENT PERSONALITY
« on: February 24, 2014, 11:48:31 AM »
A personality is your set of characteristics which is made up of our attitudes, our beliefs, our knowledge, our perceptions, our behaviours, our interests and other personal traits that we hold. Our personality communicates our quality as a person. Our pleasant personality distinguishes us and is what makes us appealing to others.

We have all met and interacted with those who have unpleasant personalities and have experienced the upsets created that come from our exchanges with them. In order to consciously create our pleasant personality we must first be aware of what our attitudes and behaviours are towards people and life.

Most of the students are interested in receiving notes or copy of lecture slides rather than going through the book thoroughly.

One of the effective way to encourage the students to read books or go to the library, is to give them chapterwise exercise question sheet where the probable answer for each question is given with page number IN ADDITION being interactive in the class. I found it very effective.
