Pregnancy poses no greater risk to breast cancer survivors

A recent study published in the Journal of the National Cancer Institute indicates that pregnancy does not incur a greater risk of relapse for survivors of breast cancer. The study found no significant difference in breast cancer recurrence rates among pregnant and non-pregnant women with a history of ER-positive breast cancer.

Researchers use a pump-induced disease to define underlying molecular mechanism

A study published in Journal of General Physiology investigated the functional effects of specific mutations in Na/K pumps found in tumors that induce primary aldosteronism. The researchers found that impaired sodium and potassium transport is a common mechanism behind the pathology, contradicting previous 'gain-of-function' proposals.

Mending hearts in three dimensions

A Kyoto-Osaka team uses hiPSCs to develop biodegradable aligned nanofibers as a scaffold for culturing cardiomyocytes, forming robust and functional cardiac tissue-like constructs. These CTLCs show excellent operability leading to favorable heart function recovery in injured rat hearts.

Doctors need cultural training

A Norwegian study reveals that general practitioners lack cultural competency when dealing with patients from diverse backgrounds. Researchers emphasize the need for mandatory cultural training in medical education to address these gaps.

Mutation in fallopian tube lesions may help catch ovarian cancer years earlier

Researchers discovered that tumor cells in the fallopian tubes of women at high-risk for ovarian cancer can be detected years before they develop into the disease, providing a potential window of time for early detection and intervention. The study identified TP53 gene mutations as an early indicator of ovarian cancer development.

A new weapon against malaria

Researchers have identified two proteases essential for the malaria parasite's survival and dissemination, as well as a molecule capable of inhibiting them. This discovery could lead to the development of drugs blocking not only the parasite's development in humans but also its transmission to mosquitoes.

Sidetracked by a donut?

A recent study published in Psychonomic Bulletin & Review found that calorie-dense foods are more distracting than low-calorie foods or everyday objects, even if they are not related to food. The researchers used a distraction paradigm to test how participants' thoughts and cognition relate to their eating habits.

Outpatient antibiotics raise risk for acquiring C. difficile infection in the community

A new study confirms outpatient antibiotic use is a primary risk factor for acquiring C. difficile infection in the community, and recent emergency department visits may also pose a risk. The study found that patients with community-associated C. difficile infections were more likely to have prior health care visits and taken antibiotics.

UBC researcher prescribes specific exercise dosage for those with spinal cord injury

Researchers developed exercise recommendations for adults with spinal cord injuries, including moderate to vigorous intensity aerobic exercise and strengthening exercises. The guidelines aim to improve fitness and reduce mortality rates among people with SCI, addressing leading causes of death such as cardiovascular disease and obesity.

How much does life weigh?

Researchers have created a novel cell scale that enables measuring the mass of living cells with high resolution and monitoring their weight changes over time. This allows tracking of fluctuations during the cell cycle, substance influence on cell mass, and viral infection effects.
