Oxytocin induces epicardial cell proliferation, study finds

The neurohormone oxytocin is well-known for promoting social bonds and generating pleasurable feelings, for example from art, exercise, or sex. But the hormone has many other functions, such as the regulation of lactation and uterine contractions in females, and the regulation of ejaculation, sperm transport, and testosterone production in males.

Love hormone can activate heart repair mechanisms after cardiac injury, study finds

Researchers show for the first time that the neurohormone oxytocin has a previously unsuspected function in both zebrafish and human cell cultures: it stimulates mature cells in the epicardium of the heart to become stem-like cells, which can replace heart cells lost after damage.

Third-trimester fetuses with in utero opioid exposure exhibit smaller brain size on MRI

According to an open-access Editor's Choice article in ARRS' American Journal of Roentgenology (AJR), third-trimester fetuses with in utero opioid exposure exhibited multiple smaller 2D biometric measurements of the brain, as well as altered fetal physiology, on investigational MRI.

The impact of sleep fragmentation on the clonal diversity of immune cells and the genetic aging of the hematopoietic system

A new study shows that sleep does much more, regulating the normal production of blood cells. This finding underlines how essential a healthy sleep routine is for a normal life.

A good night's sleep promotes immunity

In a recent study published in the Journal of Experimental Medicine, researchers in the United States used mice models to understand how sleep fragmentation affects immunological responses and the epigenetic modifications of hematopoietic stem and progenitor cells (HSPCs). They also conducted a sleep restriction trial in humans to determine HPSC programming and hematopoiesis.

Research pits the simulation of beta radiation in cancer treatment against analytical method

A new paper published in EPJ Plus and authored by Eduardo De Paiva, from the Division of Medical Physics at the Institute of Radiation Protection and Dosimetry, Rio de Janeiro, Brazil, pits the gold standard simulation method used to calculate the interaction of the ionizing radiation with matter and estimate the radiation dose delivered to a target organ—Monte Carlo (MC) simulation — against an alternative analytic method, the Loevinger formula.

Study shows differences in treatment outcomes for Black vs. white women with hormone receptor-positive breast cancer

A study led by City of Hope, one of the largest cancer research and treatment organizations in the United States, found that Black women with Stage 1 or 2 breast cancer were almost three times more likely than white women to have tumor shrinkage from hormone therapy delivered prior to surgery, yet Black women were more likely than their white counterparts to have worse outcomes when this type of endocrine therapy before surgery was used at a later stage of disease.
