A shorter time to the first cigarette of the day is associated with risk of lung cancer
Standard markers of nicotine dependency include cigarettes smoked per day, duration of smoking, and cumulative exposure (pack years), but another marker of addiction, time to first cigarette of the day, may also be associated with the risk of getting lung cancer in both heavy and light smokers, according to a study published June 19 in the JNCI: Journal of the National Cancer Institute.

Feel-good hormones could cause UV addiction
Sun lovers eagerly flock to the beach every summer, despite widespread awareness of the risk of skin cancer. A new study reveals that chronic exposure to UV radiation causes the release of feel-good hormones called endorphins, which act through the same pathway as heroin, leading to physical dependence, tolerance, and addiction-like behavior in rodents. The findings could explain why people have an instinctive desire to be in the sun, despite its known health risks.

UV-induced beta-endorphin production causes addiction-like symptoms in mice
A new study from Massachusetts General Hospital investigators adds important support to the theory that ultraviolet light can actually be addictive, finding that chronic UV exposure raises circulating levels of beta-endorphin in mice and that UV-habituated mice exhibit withdrawal symptoms if beta-endorphin activity is blocked.

New report offers a primer for doctors' use of clinical genome and exome sequencing
Sooner than almost anyone expected, a new, genome-based technology for demystifying undiagnosed illnesses -- particularly rare childhood diseases -- is moving from research laboratories into general medical practice. Now, two leading scientists, writing in the June 19, 2014, issue of the New England Journal of Medicine, have sketched out what doctors need to know in order to use the new technology effectively.

Racial disparities in sentinel lymph node biopsy in women with breast cancer
The use of sentinel lymph node biopsy to stage early breast cancer increased in both black and white women from 2002 to 2007, but the rates remained lower in black than white patients, a disparity that contributed to disparities in the risk for lymphedema (arm swelling common after breast cancer treatment because of damage to the lymphatic system).

Vaccine 'reprograms' pancreatic cancers to respond to immunotherapy
Researchers at the Johns Hopkins Kimmel Cancer Center have developed and tested a vaccine that triggered the growth of immune cell nodules within pancreatic tumors, essentially reprogramming these intractable cancers and potentially making them vulnerable to immune-based therapies.

Study shows cost-effectiveness of smoking cessation counseling during hospitalization

Breathalyzer test may detect deadliest cancer
Lung cancer causes more deaths in the US than the next three most common cancers combined. Now a new breathalyzer test, embedded with a 'NaNose' nanotech chip to literally 'sniff out' cancer tumors, has been developed by a team of international researchers including Prof. Nir Peled of Tel Aviv University's Sackler Faculty of Medicine. It may turn the tide by both accurately detecting lung cancer and identifying its stage of progression.

Following direction: How neurons can tell top from bottom and front from back
The question of how neurons and their axons establish spatial polarity and direction in tissues and organs is a fundamental question of any organism or biological system. Our cells and axons precisely orient themselves in response to external cues, but what are the core pathways and how are they integrated?

Study compares survival for treatments of uncommon eye cancer
In patients with advanced uveal melanoma, treatment with the agent selumetinib, compared with chemotherapy, resulted in an improved cancer progression-free survival time and tumor response rate, but no improvement in overall survival, according to a study in the June 18 issue of JAMA. The modest improvement in clinical outcomes was accompanied by a high rate of adverse events.

TNF inhibitors for treatment of bowel disease not linked with increased risk of cancer
In a study that included more than 56,000 patients with inflammatory bowel disease, use of a popular class of medications known as tumor necrosis factor alpha antagonists was not associated with an increased risk of cancer over a median follow-up of 3.7 years, although an increased risk of malignancy in the long term, or with increasing number of doses, cannot be excluded, according to a study in the June 18 issue of JAMA.

Heparin derivative suppresses neuroblastoma tumor growth
Researchers at Duke Medicine have identified a new strategy for treating neuroblastoma using a modified version of heparin, a century-old injectable drug that thins the blood to prevent clots from forming. The study, conducted in mice and published June 17, 2014, in the Journal of Clinical Investigation, found that when heparin is altered to remove its blood-thinning properties, it can suppress and shrink neuroblastoma tumors without causing severe bleeding.
