#Nivolumab helps fight Cancerous Lung Tumors A trial has suggested that a therapy for lung cancer has the ability to double the life expectancy in patients.
Lung cancer, which is also known as carcinoma of the lung, is the deadliest form of cancer that kills about 1. 6 million people every year.
It is difficult to treat the cancer as it is usually diagnosed late. In addition a number of patients are found unsuitable for surgery due to their smoking-related diseases.
Nivolumab is among the set of drugs known as heckpoint inhibitorsthat are developed by a number of pharmaceutical companies.
Those drugs stop cancers by turning off the immune system of human so that it could keep on attacking the harmful tumor.
The new trial was conducted in the United states and Europe on people with advanced lung cancer. Those people had tried already other treatments,
but didn receive satisfactory results. As per the trial results, patients on standard therapy lived for about 9. 4 months
Those whose tumors were producing high levels of PD-L1 lived for more than one and half year.

OCT Could Aid Brain tumor Removal Study: OCT Could Aid Brain tumor Removalbaltimore, June 19, 2015 Optical coherence tomography (OCT) holds promise for guiding surgeons as they operate on brain tumors

"We envision that the OCT would be aimed at the area being operated on, and the surgeon could look at a screen to get a continuously updated picture of where the cancer is

#Telomerase Cancer cell Mutation Mystery Solved More than 500,000 people in the United states die each year of cancer-related causes
and a new study has identified the mechanism behind one of the most common mutations that help cancer cells replicate limitlessly.
Recent cancer research has shown that highly recurrent mutations in the promoter of the TERT gene are the most common genetic mutations in many cancers,
including adult glioblastoma and hepatocellular carcinoma. TERT stabilizes chromosomes by elongating the protective element at the end of each chromosome in a cell.
which these common mutations result in elevated TERT expression by using computational and experimental analyses to determine that the mechanism of increased TERT expression in tumor tissue relies on a specific transcription factor-a protein that binds specific DNA sequences
and binds the mutant TERT promoter in tumor cells from four different cancer types, underscoring that this is a common mechanism of TERT reactivation.
The identified transcription factor and its regulators have great potential for the development of new precision therapeutic interventions in cancers that harbor the TERT mutations.
#Could There Be An Asthma Cure Within Five Years? A recent study has revealed a breakthrough in asthma research might be on the horizon.
Following extensive research carried out across a number of institutions, it has been discovered that protein molecules-known as calcium-sensing receptors-have a vital role in asthma.
Although they have not previously been used to treat asthma, there is already medication available (calcilytics) that could be used to block these proteins.
In asthmatics, the immune system essentially misidentifies harmless substances, such as pollen for example, as a threat. The airways then restrict in an attempt to keep the armfulsubstances from entering the lungs leading to the body facing constricted airways and
Based on the study, the researchers concluded that this is one of the main reasons for the excessive inflammatory responses that occur in people with asthma.
