RNA Aptamer A Potential New Weapon In Fight Against Cervical Cancer
Date: Jun-03-2013Scientists at the University of Leeds have found a way to target and destroy a key protein associated with the development of cervical and other cancers. The E7 protein is produced early in the lifecycle of the human papillomavirus (HPV) and blocks the body's natural defences against the uncontrolled division of cells that can lead to cancer...
Protection Against Post-Influenza Bacterial Superinfection Offered By Interleukin-22
Date: Jun-03-2013Researchers from the Pasteur Institute, Lille, France have shown in a mouse model that interleukin-22 protects against bacterial superinfections that can arise following influenza. Their research is published in the June 2013 issue of the Journal of Virology. Influenza A viral infection can lead to primary pneumonia and, later on, to serious complications including secondary bacterial pneumonia and sepsis. Post-influenza bacterial superinfections that occur during seasonal epidemics and pandemics are of great concern to human health and impose a considerable socio-economic burden...
A Staggering 6 Out Of Every 10 People On Earth Still Lack Access To Flush Toilets, Adequate Sanitation
Date: Jun-03-2013The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes research concluding that the number of people without access to flush toilets or other adequate sanitation is almost double the previous estimate. Based on a report by Jamie Bartram, Ph.D., and colleagues in ACS' journal Environmental Science & Technology, the new podcast is available without charge at iTunes and from http://www.acs.org/globalchallenges...
The GRACE Study: Insights Into Gender, Race, And HIV Therapy
Date: Jun-03-2013Enrollment of women in clinical trials of new anti-HIV drugs is extremely low, representing only about 15% of all treatment-experienced patients. For women of color it is even lower. Why women, and especially women of color, are so poorly represented in HIV drug trials is the focus of an important article in AIDS Patient Care and STDs, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available on the AIDS Patient Care and STDs website*...
New Ovarian Hormone Discovered That Makes Ovaries Grow
Date: Jun-03-2013A newly discovered hormone produced by the eggs of human females may improve the effectiveness of current fertility treatments for women and possibly lead to entirely new treatments altogether. According to new research published in the June 2013 issue of The FASEB Journal, researchers from Stanford and Akira University in Japan identified a new hormone called "R-spondin2" that promotes follicle development and stimulates ovary growth...
Funding Cuts Could Halt Advances Against Cancer
Date: Jun-03-2013The rate of advances in clinical cancer research could stagnate after the recent cuts to biomedical research funding in the United States, warns ASCO President, President Sandra M. Swain, MD, FACP, in a briefing of the Society's 49th Annual Meeting in Chicago, Illinois. ASCO (American Society of Clinical Oncology) has released a report " Blueprint for Transforming Clinical and Translational Cancer Research" which details the gains made toward achieving clinical cancer research goals. Dr...
Snapshot Of Fleeting Protein Process Shows How Actin Nucleation Begins
Date: Jun-03-2013Structural biologists from Rice University and Baylor College of Medicine (BCM) have captured the first three-dimensional crystalline snapshot of a critical but fleeting process that takes place thousands of times per second in each human cell. The research appears online in the journal Cell Reports and could prove useful in the study of cancer and other diseases. The biological "freeze-frame" shows the initial step in the formation of actin, a sturdy strand-like filament that is vital for humans. Actin filaments help cells maintain their shape...
First Drug To Help Melanoma Of The Eye
Date: Jun-02-2013AstraZeneca's experimental drug, selumetinib, is the first targeted medication to show a significant clinical benefit for patients with melanoma of the eye (metastatic uveal melanoma), researchers from the Memorial Sloan-Kettering Cancer Center explained at the 49th annual meeting of the American Society of Clinical Oncology (ASCO), in Chicago, Illinois. The scientists say that their findings will probably change clinical practice for patients with metastatic uveal melanoma, which to date has been an "untreatable disease"...
Some Patients With Treatment-Resistant Colorectal Cancers May Have A New Option
Date: Jun-02-2013A subset of colorectal cancers responds to anti-epidermal growth factor receptor (anti-EGFR) therapies, but develops resistance within months. Among cancers that develop resistance to anti-EGFR therapy, some showed overexpression of a gene called MET, according to a study published in the June issue of Cancer Discovery, a journal of the American Association for Cancer Research. Preliminary data published in this study showed human tumors with MET amplification, grown in mice, responded to MET inhibitor drugs...
Facebook May Boost Self Esteem But Reduce Motivation
Date: Jun-02-2013New research published in Media Psychology suggests that looking at your Facebook profile can be psychologically good and bad for you. The finding revealed that checking your profile is capable of boosting your self esteem while at the same time reducing motivation. A person's Facebook profile is essentially an ideal representation of one's self published online for friends and family to see. Using Facebook and looking at your profile page can boost self esteem, but it can also reduce motivation to perform well in simple tasks, according to results of the study...
