BRAIN CANCER

Image
A brain tumour is a  massive growth of abnormal cells in the brain. There are many different types of brain tumours some of them are non-cancerous (benign) and a few are cancerous (malignant). Brain tumours share some feattumourures and challenges for diagnosis and therapy with tumours elsewhere in the body. Most of the brain is separated from Blood-Brain Barrier (BBB) that exerts a much more restrictive control over substances that are allowed to pass through to other organs. There are around 120-150 different types of brain and central nervous system tumours that have been documented so far. According to 2012 data globally there were nearly 2,60,000 reported cases of brain and nervous system cancer around the world. It is the 22nd most common cancer worldwide with 1.8% total number of new cases worldwide. And according to the mortality rate, it ranks 12th. TYPES OF TUMORS: A Tumor is simply a mass of cells that are classified into two types are Benign tumour a

GENETIC BASIS OF FEMALE INFERTILITY

Image
  INTRODUCTION:- Definition: Infertility is defined as a failure to conceive in regular intercourse within 1 year for women younger than 35 years, and within 6 months for women older than 35 years.  The prevalence of infertility is between 7% to 15%. There are many causes of infertility such as ovulatory disorder, chromosomal abnormality, endometriosis, pelvic adhesions, tubal blockage and other tubal abnormalities, and hyperprolactinemia. In ovulatory disorder also include fragile X syndrome and Kallmann syndrome, ovarian leukodystrophy. Approximately 10% of infertile females have genetic abnormalities. There also evidence that chromosomal abnormalities and single-gene mutations contribute to causing infertility. If a woman keeps having miscarriages, it is also known as infertility. Most cases of infertility in a woman are due to the problems of producing an egg. In primary ovarian insufficiency - the ovaries stop functioning before natural menopause. In PolyCystic Ovary Syndrome (PC

Story behind AMBER EYES??

       Picture credit:- Blushin.com   Amber  eyes, these are very unique and special eyes because their iris are in the shade of brown mixed with gold and copper strings, which look very beautiful and unique when seen in sunlight. I decided to write about this because it is one of the rare eye colours and only approximately 5% of the world's population have amber eyes, which are rare. There are other rare eye colours as well which I would like to share with you all on my upcoming blog posts. But for today I would first like to start with AMBER EYES. WHAT ARE EYE COLOURS, AND HOW DOES THE GENES ARE INVOLVED IN THE CHANGE IN THEIR COLOURS?    Eye colour is a  polygenic phenotypic character. The eye colour of a person is determined either by  the pigment of the iris or by the scattering of the light by the turbid medium in the stroma of the iris .  Eye colour is mostly depended on the concentration of the melanin.  As we all know that coloured part of our eyes is called IRIS,

Did you know that asbestos dust can sometimes lead to an aggressive cancer?

  Yes, what you just read is the truth asbestos dust can lead to aggressive cancer known as MESOTHELIOMA CANCER   which may not be as popular as other cancers as it is a very rare disease. There hasn't been a cure for such kind of cancer yet as it is very rare and very aggressive as well. as it is such rare and aggressive  disease  research on such kind of cancers has also become very challenging. Asbestos  exposure is mostly found in nature as they are present in the dust particles of mines. these particles accumulate in the lungs or the stomach and get converted into mesothelioma which will be detected after 20-40 years . Mesothelioma has a very high specific tumour cell antigen.    INTRODUCTION:- MESOTHELIOMA CANCER was first identified in  Germany in 1977 . But in general, the  tumour in the lining of lungs was first identified in the year 1767. Tumour in the lining of the lungs is considered because " mesothelial cells"  mostly affect the lining of the lu
