What is HIV all about?
Human immunodeficiency virus is a condition which causes progressive
failure of immune system and allows dangerous infections and cancers to
prosper. Infection with HIV is caused by transfer of blood, semen, vaginal
fluids and breast milk. The major routes of transmission include unsafe
sex, contaminated needles, breast milk and from an infected mother to
The latest story about this topic is that scientist at ULCA have proved
that engineered stem cells can really attack HIV infected cells in a living
organism. In a previous study researchers found that killer T cells contain
T cell receptors which help the killer cells to identify and kill the HIV
infected cells. But the sad part was that their numbers were not sufficient
to clear the virus from the body.
But the present study can be said as a boon in many ways. The researchers
cloned the T receptors and used it to engineer genetically human blood stem
cells. These cells were placed in human thymus tissue and implanted into
mice. Long story cut short these cells developed into large number of
mature cells that could specifically target cells containing HIV proteins.
But one thing is that the HIV specific T cell receptors should be a perfect
match to the individual in order to kill the virus.
Now the next step of the researchers will be to make T cell receptors
target different parts of HIV and which can be used in more genetically
matched individuals. The scientists believe that this method will be efficient
in eradicating the HIV virus from the body of infected persons. Let us hope
and pray that they should be successful in their attempt.
The butterfly-shaped gland in your neck, the thyroid has a dramatic impact on a variety of bodily functions. According to estimates if you’re woman of over 35 your chances of a thyroid disorder are more by 30 percent. Experts say that women are as much as ten times as likely as men to have a thyroid problem. Your thyroid gland is located above Adam’s apple. The thyroid hormone (TH) among other things regulates your body’s temperature, metabolism, and heartbeat. When your thyroid gland turns sluggish, it produces too little TH. The condition is known as hypothyroidism. Hypothyroidism in India is 11 percent. Cities like Delhi, Kolkata, Bangalore, Ahmadabad, and Hyderabad has a higher prevalence compared to coastal cities such as Mumbai, Goa, and Chennai. Thyroid hormone has a far reach in the body from your brain to bowels, so diagnosing a disorder can be challenging. Here are some tell-tale signs to find whether your thyroid is on the blink. üYou’re exhausted üYou’re feeling weak üAlways su…
Facial exercises are
hailed as a non-invasive alternative to Botox and surgery. You can take
years off your face by just doing some facial exercises. Yep and this fact has
a strong scientific backing to it. Facial
exercises may improve facial appearance and reduce some visible signs of aging
says a recently published research study. "Assuming the findings are
confirmed in a larger study, individuals now have a low-cost, non-toxic way for
looking younger or to augment other cosmetic or anti-aging treatments they may
be seeking," says lead author Dr. Murad Alam, vice chair and professor of
dermatology at Northwestern University Feinberg School of Medicine and a
Northwestern Medicine dermatologist. When you perform facial exercises, they enlarge and strengthen your facial muscles making
your face more toned and younger looking. ‘The exercises
work the hypodermis or the lower layer of the skin, the dermis or the middle
layer and the epidermis or the upper layer.
