Higher cancer incidences found in regions near refineries and plants that release benzene

The incidence of a particular type of blood cancer is significantly higher in regions near facilities that release the chemical benzene into the environment. That is the conclusion of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. This and other studies like it will be critical to identifying and enacting public health policies to decrease or prevent cancer.

UT Southwestern researchers identify novel mechanism that helps stomach bug cause illness

DALLAS – July 29, 2013 – A seafood contaminant that thrives in brackish water during the summer works like a spy to infiltrate cells and quickly open communication channels to sicken the host, researchers at UT Southwestern Medical Center report.

Coronary artery disease continues to be neglected in women, despite it killing at least as many women as men

Despite coronary artery disease (CAD) killing at least as many women as men each year, women are still today less likely to receive preventive recommendations, such as lipid-lowering therapy, aspirin, and lifestyle advice, than are men at a similar risk level. The challenges for women with CAD are outlined in a paper in this month's edition of Global Heart, the journal of the World Heart Federation. The paper, titled 'Coronary Artery Disease in Women: A 2013 Update', is by Dr Kavita Sharma and Dr Martha Gulati, The Ohio State University, Columbus, OH, USA.

Breakthrough in detecting DNA mutations could help treat tuberculosis, cancer

The slightest variation in a sequence of DNA can have profound effects. Modern genomics has shown that just one mutation can be the difference between successfully treating a disease and having it spread rampantly throughout the body.

Water molecules control inactivation and recovery of potassium channels

Just 12 molecules of water cause the long post-activation recovery period required by potassium ion channels before they can function again. Using molecular simulations that modeled a potassium channel and its immediate cellular environment, atom for atom, University of Chicago scientists have revealed this new mechanism in the function of a nearly universal biological structure, with implications ranging from fundamental biology to the design of pharmaceuticals. Their findings were published online July 28 in Nature.

Mucopolysaccharidosis Type IIIA potential gene therapy

Mucopolysaccharidosis Type IIIA (MPSIIIA) is a metabolic disorder in which the body is missing an enzyme that is required to break down long chains of sugars known as glycosaminoglycans.

Over time, the glycosaminoglycans collect in the body and cause damage, particularly in the brain. In the Journal of Clinical Investigation, Fàtima Bosch and colleagues at Universitat Autònoma de Barcelona in Spain developed a form of gene therapy to replace the enzyme that is missing in MPSIIIA.

Scouring the genome of adenoid cystic carcinoma

Adenoid cystic carcinoma (ACC) is a slow-growing and often fatal malignancy that can occur at multiple organ site, but is most frequently found in the salivary glands.

The primary treatment is surgical removal; however, the majority of patients develop metastatic disease.

In the Journal of Clinical Investigation, researchers led by Andrew Futreal at the Wellcome Trust Sanger Institute in Cambridge, MA, performed a type of genetic sequencing known as whole exome sequencing of 24 ACC cases.

Mutant strain of zebrafish is an alternative model for Rett syndrome in humans

An important challenge for neuroscientists is to find cures for diseases that affect the central nervous system, such as autism, Alzheimer's, or Parkinson's disease.

For this purpose, researchers use several vertebrate species as model organisms. The zebrafish has recently received much attention because it has many advantages over other vertebrate models. For example, development of its nervous system can be followed from its earliest stages in naturally behaving individuals.

HIV-associated lymphoma survival has not improved during the antiretroviral therapy era

Stable survival rates were observed for HIV-associated lymphoma patients during the antiretroviral therapy (ART) era in the US, according to a new study published July 26 in the Journal of the National Cancer Institute.

Evolution on the inside track: How viruses in gut bacteria change over time

PHILADELPHIA — Humans are far more than merely the sum total of all the cells that form the organs and tissues. The digestive tract is also home to a vast colony of bacteria of all varieties, as well as the myriad viruses that prey upon them. Because the types of bacteria carried inside the body vary from person to person, so does this viral population, known as the virome.

Singapore scientists discover new drug targets for aggressive breast cancer

25th July 2013 - Scientists at A*STAR's Genome Institute of Singapore (GIS) led in a study that has identified genes that are potential targets for therapeutic drugs against aggressive breast cancer. These findings were reported in the July 2013 issue of PNAS.

Why are consumers less likely to buy a product when it's the only option?

Consumers are more likely to search for alternatives when they are given only one option, according to a new study in the Journal of Consumer Research.

"There has been a lot of recent attention devoted to the pitfalls of presenting consumers with too many options. However, consumers may also react negatively when choices are too restrictive. Isolating an option, even temporarily, may increase how much consumers search and potentially the likelihood that they make no purchase," writes author Daniel Mochon (Tulane University).

Empowering your customers? Think twice about social media campaigns

Companies that empower consumers by involving them in important processes such as product development shouldn't also try to influence them through social media, according to a new study in the Journal of Consumer Research.

"Peer-to-peer marketing and consumer empowerment may not be compatible. Empowered consumers resist social influence by either discounting the opinions of others or deliberately expressing opinions that diverge from those of other consumers," write authors Mehdi Mourali (University of Calgary) and Zhiyong Yang (University of Texas, Arlington).

Buying a used car? Be sure to flatter the seller

Consumers set high prices when selling their possessions because they feel threatened, according to a new study in the Journal of Consumer Research.

"When consumers consider selling a product they own, they feel threatened by the impending loss. In order to counter this threat, they increase the product's value," write authors Promothesh Chatterjee (University of Kansas), Caglar Irmak (University of Georgia), and Randall L. Rose (University of South Carolina).

Legendary brands: Why are consumers still fascinated by the Titanic?

Brands do not necessarily need to present a clear, well-defined image in order to appeal to consumers, according to a new study in the Journal of Consumer Research. Consider the case of the Titanic.
