Skin Diseases
The skin is the largest organ of the body. It forms a protective barrier against germs and other organisms, and keeps the inside of our body protected from external environment. Skin also helps to maintain a constant body temperature. Human skin is only about 0.07 inches (2 mm) thick.
Skin is made up of two layers that cover a third fatty layer. The outer layer is called the epidermis; it is a tough protective layer that contains melanin, which protects against the rays of the sun and gives the skin its color. The second layer located under the epidermis is called the dermis; it contains nerve endings, sweat glands, oil glands, and hair follicles. Under these two skin layers is a fatty layer of subcutaneous tissue.On average, an adult has from 18-20 square feet (about 2 square meters) of skin, which weighs about 6 pounds (2.7 kg).

Zika Virus could help in the treatment of Brain Tumour

The Zika virus is well known for causing devastating brain defects in fetuses. Scientists have come out with a novel idea of using this virus as an ammunition to


attack a deadly brain tumour Glioblastoma.

Most people with a glioblastoma die within two years of being diagnosed even with aggressive treatment available at present.

In lab and animal experiments, scientists from Washington University School of Medicine in St. Louis and the University of California, San Diego, showed — that the virus was able to target and destroy stem cells that drive the growth of a deadly and common type of brain tumour, known as a glioblastoma.

Researchers also found that a modified strain of Zika virus slowed tumor growth among mice with aggressive brain tumours, and extending their lives.

The effectiveness of the virus was enhanced when combined with a chemotherapy drug, known as temozolomide, which is being presently used in the treatment of Glioblastoma with poor results.

Such studies are first few steps towards the development of safe and effective strains of Zika virus that could become important tools in neuro-oncology and the treatment of glioblastoma,
