Researchers sequence non-infiltrating bladder cancer exome Posted: 13 Oct 2013 01:36 PM PDT Researchers have carried out the first exome sequencing for non-infiltrating bladder cancer, the most frequent type of bladder cancer and the one with the highest risk of recurrence. The results reveal new genetic pathways involved in the disease, such as cellular division and DNA repair, as well as new genes—not previously described—that might be crucial for understanding its origin and evolution.

In a surprise finding, gene mutation found linked to low-risk bladder cancer Posted: 13 Oct 2013 01:36 PM PDT An international research team has discovered a genetic mutation linked to low-risk bladder cancer. The investigators identified STAG2 as one of the most commonly mutated genes in bladder cancer, particularly in tumors that do not spread. The finding suggests that checking the status of the gene may help identify patients who might do unusually well following cancer treatment.

The role of 'master regulators' in gene mutations and disease Posted: 13 Oct 2013 01:33 PM PDT Researchers have developed a new way to parse and understand how special proteins called "master regulators" read the genome, and consequently turn genes on and off.

Kids having tonsils removed get better pain relief with IV acetaminophen Posted: 13 Oct 2013 09:17 AM PDT Using intravenous (IV) acetaminophen with narcotics provides more effective pain relief to children having tonsillectomies, according to a study. Additionally, the combination therapy saves costs due to reduced use of narcotics after surgery, reduced side effects and slightly quicker hospital discharge than in patients who receive narcotics alone.

When med students' iPad use for instruction goes up, personal use goes down Posted: 13 Oct 2013 09:17 AM PDT With the entry of "Millenials" into medical residency programs across the country, institutions have started to examine ways to improve programs to correspond with that generation's learning behaviors and preferences. A study has found that Millennial residents use their iPads to enhance their educational experience. Surprisingly, as residents increased use of their iPad for educational purposes, their personal iPad use decreased significantly.

Women in labor can ditch ice chips, drink protein shake instead Posted: 13 Oct 2013 09:17 AM PDT Women in labor can enjoy a chocolate or vanilla protein shake during labor rather than being relegated to the tedium of ice chips, according to a study. Mothers who drank a protein drink during childbirth reported higher satisfaction rates, although nausea and vomiting rates were the same as for mothers who were only given ice chips.

State executions threaten propofol supply Posted: 13 Oct 2013 09:17 AM PDT Propofol has never been used for executions, but some states are considering changes to their lethal injection protocols due to market unavailability of barbiturates that have been previously used.

People born with certain gene more likely to suffer cognitive decline after heart surgery Posted: 13 Oct 2013 09:17 AM PDT Long-term memory loss, difficulty understanding verbal or written communication or impaired ability to pay attention may still occur five years after heart surgery if a patient has a certain gene variation, according to a study. This gene was found to be related to a decline in cognitive capabilities compared to those who do not have the variation.

Chronic pain treatment cools hot flashes in menopausal women Posted: 12 Oct 2013 01:01 PM PDT Menopausal women suffer from half as many hot flashes after receiving a non-hormonal chronic pain treatment. The nerve block treatment interrupts the area of the brain that regulates body temperature, reducing moderate-to-severe hot flashes and alleviating depression in menopausal women, breast cancer patients and women in surgical menopause.

Safety impacts of advanced car headlight systems evaluated Posted: 11 Oct 2013 12:31 PM PDT Scientists are evaluating the potential for new lighting technologies and approaches to improve driving safety at night, including new car headlight systems—swiveling or bending headlights that direct light into roadway curves, and adaptive or glare-free high beam headlight systems, which allow drivers to use high beam headlights while selectively dimming a portion of the beam when oncoming drivers are present, preventing glare to the oncoming drivers while providing improved visibility along the rest of the road.

Predators vs. alien: European shrimps win predatory battles with an American invader Posted: 11 Oct 2013 10:53 AM PDT Ecologists have discovered that native European shrimps resist the invasion of lakes and rivers by an American shrimp, by killing and eating the colonists.
