Decible (dB)

Decibel (dBA) is an International Scale of Sound Levels.

Decibel (symbol dB) is unit of measure used originally to compare sound intensities. Nearly all audible sounds lie between 0 and about 140 dB, where 0 dB is the 'threshold of hearing. A whisper has a sound intensity of 20 dB and 140 dB (a jet aircraft taking off nearby) is the threshold of pain. An increase of 10 dB means that the noise perceived by a listener has roughly doubled in loudness. A car passing at 70 dB sounds twice as loud as one passing at 60 dB. The dB measurement is widely used throughout the world for determining approximate human reaction to noise.

People who have Dimples, Tend to have Children with Dimples

People who have Dimples, Tend to have Children with Dimples
A dimple is the word given to natural indentation on the face. Dimples often occur on both the cheeks. They are most commonly visible when someone smiles. Dimples are due to a genetic trait following an autosomal dominant pattern of inheritance. Transfer of dimples from parents to children occurs due to just one gene. Dimples are highly heritable, meaning that people who have dimples tend to have children with dimples. The truth is that dimples are actually genetic defects that are revealed by shortened facial muscles. Dimples are caused by a fault in the subcutaneous connective tissue that develops in the course of the embryonic development.

Achondroplasia is Inherited Condition of Abnormal Cartilage Development

Achondroplasia is Inherited Condition of Abnormal Cartilage Development
Achondroplasia is a disorder, inherited as a dominant characteristic, in which the bones of the arms and legs fail to grow to normal size due to a defect in both cartilage and bone. It results in a type of dwarfism characterized by short limbs, a normal-sized head and body, and normal intelligence. Achondroplasia is the commonest form of human dwarfism. The condition is controlled by an autosomal dominant gene and thus affected children born to normal parents must result from a mutation in one or other parent. The majority of achondroplastics die in early childhood but those surviving are fertile.


Ability to set Goals

The ability to set Goals and make plans for there accomplishment is the master Skill of success.
Developing this skill will do more to ensure your success than anything else you could ever do.
Goals are the fuel in the furnace of achievement. A person without goals is like a ship without a rudder, drifting aimlessly and always in danger of ending up on the rocks. A person with goals is like a ship with a rudder, guided by a captain with a map, a compass, and a destination, sailing straight and true toward a port of his own choosing.

You are where you are and what you are because you have decided to be there. Your thoughts, your actions and your behaviour have gotten you to your present position in life, and they could have brought you to no other place, rightly considered.

If your goal is to get through the day and then get home and watch tv, you will achieve it. If your goal is to be fit and healthy and to live a long life, then you will achieve that too. And if your goal is to be financially independent or even wealthy, if that is truly your goal, then there is nothing that can stop you from reaching it, sooner or later.

Your only limitation is your desire, How badly do you want it.

Hemophilia

Hemophilia is Inherited Blood Disorder Resulting Severe Bleeding
Haemophilia is a rare human blood disorder in which blood clots very slowly, resulting often in severe bleeding internally and externally. The condition is due to a lack of fibrin in the blood and is controlled by two closely linked genes on the X-chromosome that are responsible for the production of different clotting factors. Haemophilia A individuals lack antihaemophilic factor, while haemophilia B individuals lack plasma thromboplastin. Males carrying the mutant alleles will be affected, although heterozygous females have normal blood. The patient may experience prolonged bleeding following any injury or wound. Haemophilia may be treated by transfusions of plasma (which contains the missing factor).

Visual Acuity

Visual Acuity Commonly Refers to the Clarity of Vision.
Visual acuity describes how well you see detail with your central vision. This is usually measured using a special chart with rows of letters that start with one big one at the top and get smaller row by row - called a Snellen scale. There are many tests of visual acuity. One of the more common is the Snellen test type. This is made up of many letters of different size. By conventions the chart is placed 6 metres away from the patient. Each eye is assessed with two numbers, such as having 6/6 vision. The first number is the distance the chart is viewed from. The second is the distance at which the person being tested can see a letter clearly. If they are only able to see the top letter they have 6/60 vision. ‘Normal’ vision is 6/6.

Biofilm

Biofilm is a Collection of Micro-Organisms and their Products.
Biofilm is a collection of microbial cells covered by and embedded in a matrix of extracellular  microbial products, such as mucilage or slime, at an interface. Biofilms are found, for example, on the surface of stones in rivers and ponds, in water pipelines, as dental plaques on teeth and on surgical implants. Biofilm formation can have serious implications in industrial, environmental, medical and public health situations. Biofilms form in the micro-environment (rhizosphere) surrounding plant roots, where they assist the plant in absorbing nutrients from the soil.

Lessons from Ebola: how to reach the poorest children when schools reopen

When schools reopen after a crisis, we can't assume that all students will return.

These are some of the lessons learnt from Ebola, that we must urgently apply to COVID-19.

Liver is my Lover

Liver is my Lover



  •  The liver is the largest internal and most metabolically complex organ in humans.
  • Liver is also the largest gland in our body.
  • The weigh of human liver is about 1.5 kg.
  • The study of liver is known as Hepatology. (The Greek word for liver is hepar). 
The liver performs over 500 different functions. Some of them are
a. Figh against infections
b. Neutralize toxin and harmful chemicals such as liquor, beer, wine and drugs.
c. Detoxify food impurities
d. inspects nutrients before allowing them into the bloodstream.
e. Manufacture proteins and hormones.
f. Control blood sugar level.
g. Help to clot the blood.
h. Store iron and other important vitamins and minerals.
i. Enable to digest the fat in your food by releasing bile juice.
j. Store glucose in the form of glycogen.
k. Synthesize cholesterol.


  •  The liver is the only organ that can regenerate itself!! So one can donate a part of his liver to another person. When a portion of the liver is transplanted, the donor's liver will regenerate back to its original size while the transplanted portion will grow to the appropriate size for the recipient. 
  • About 1.4 litre of bile juice is produced daily.G
  • Gall bladder stores bile from the liver. It is used to break down dietary fat into tiny droplets. It facilitates the fat digestion.T
  • The liver always contains about 10% of the blood in your body and it pumps about 1.4 litres through per minute. 
  • The first human liver transplantation was performed by Dr. Thomas E. Starzl (1963). But it was not 100% successful due to lack of immunosuppressive drugs. Four years later, he performed first successful liver transplantation. 
  • Hepatitis B (a viral disease) is one of the most serious forms of hepatitis. The National Liver Foundation reports Hepatitis B is more common and much more infectious than AIDS.
  • Chronic Hepatitis B leads to liver cirrhosis (damaging of the liver cells). 
  • One glass of wine, a can of beer or a shot of whiskey can be equally damaging to the liver.
  • Alcoholism mostly attacks the liver. It leads to the damage of liver tissues called liver cirrhosis.
  • If you avoid alcohol during the week and, then, binge drink on the weekends, this is also bad and may cause even greater damage.
  • Anyone who drinks more than five drinks per day is at serious risk of developing alcoholic liver disease.

Liver cancer

How to take care of your liver?


  • Avoid alcohol completely.
  • Avoid excessive use of drugs you take. Do not use any drugs without the advice of doctors.
  • Take care about the aerosol sprays you breathe. Your liver detoxifies what you breathe in. When you’re around aerosol cleaners, mildew sprays and paint sprays, for example, make sure the room is well ventilated or wear a mask.
  • Every time you are around insecticides, cover your skin with gloves, long sleeves, a hat and mask. These harmful chemicals can enter your body through your skin and destroy cells in the liver.
  • Don’t expose yourself to hepatitis viruses. They live in bodily fluids, blood, saliva and seminal fluid.
  • Eat a well balanced, healthy diet without too much fat.
