December 1 is World AIDS Day, an annual event dedicated to raising awareness and money to fight AIDS around the world.
Over the last four decades, HIV and AIDS have been at the forefront of advocacy and research. But despite medical advances, AIDS remains one of the most destructive pandemics in history, particularly of youth.
HIV treatments have come a long way in the more than 30 years since the virus was first identified.
Powerful antiretroviral drugs (ARVs) can now keep the virus controlled at levels that current tests cannot detect in the blood. Perhaps just as important, people who take these drugs diligently soon after they’re infected are unlikely to pass the virus to others. But the treatment isn’t perfect. Those with HIV need to take a pill every day for the rest of their lives, and even if they do, the virus can easily morph to become resistant to the drugs. That’s why patients on ARV treatment should faithfully monitor their virus and cycle between different combinations of drugs.
Finding new, easier ways to more effectively treat HIV and stop its spread is therefore an urgent priority, and researchers are now looking beyond daily drugs to therapies that might provide people with more lasting protection.
But while screening can be extremely helpful, it also carries some risks. Here’s what you need to know about lung cancer screenings.
How does lung cancer screening work?
Currently, there’s only one recommended screening test for lung cancer: low-dose computer tomography (low-dose CT scan). This test creates images of the inside of the body — or in this case, the lungs — using low doses of radiation.
The OriHime-D can also be used by people involved in childcare, nursing care or other activities that prevent them from leaving home or a certain location.
A cafe with an all-robot staff controlled by paralyzed people has opened in Tokyo.
The cafe, called Dawn ver.β, held its ribbon cutting ceremony on Nov. 26.
Hundreds of children with cancer are resorting to inferior treatment because of a failure to open two flagship specialist centres, experts have warned.
NHS officials have admitted that no patient has yet received state-of-the-art proton beam therapy (PBT) at either its new London or Manchester sites, despite a Government pledge to be treating 1,500 a year by 2018.
Leading oncologists have called for transparency after two promised opening dates at The Christie NHS Foundation Trust were missed this year and the deadline quietly pushed back.
NANJING — Chinese researchers have developed a new evaluating model using medical imaging to help painlessly evaluate tumor progression in patients.
Doctors usually use the biological characteristics of tumors to observe the progress and response to treatment, such as if there are gene mutations or malignant features. Previous studies have shown that identifying the biological characteristics may contribute to better treatment and may increase survival rates.
Traditional methods to get tumor tissue include surgery and puncture, which are invasive, painful and costly.
In the summer of 1968, while a visitor in CERN’s theory division, Gabriele Veneziano wrote a paper titled “Construction of a crossing-symmetric, Regge behaved amplitude for linearly-rising trajectories”. He was trying to explain the strong interaction, but his paper wound up marking the beginning of string theory.
Researchers have identified over 6,000 antibiotic resistance genes found in bacteria that inhabit the human gut, which is home to trillions of micro-organisms, mainly bacteria.
“Most gut bacteria live in a harmless relationship with the human host. However, the gut is also home to bacteria that can cause infections in hospitalised patients,” said one of the researchers Willem van Schaik, Professor at the University of Birmingham.
“Unfortunately, these bacteria are becoming increasingly resistant to antibiotics and we need to understand the processes that contribute to this development,” he added.
