Multiscale 3-D mathematical model of uterine contractions may aid in predicting preterm birth

Although researchers have been seeking the origins of preterm birth for many years, the causes are still relatively unknown. By studying the electrical activity that causes contractions, researchers at Washington University in St. Louis and their collaborators have developed a multiscale model they believe may aid in predicting preterm birth.

New research defies earlier belief that calcium channels function independently

Voltage-gated calcium channels open in unison, rather than independently, to allow calcium ions into and activate excitable cells such as neurons and muscle cells, researchers with UC Davis Health System and the University of Washington have found.

Selenium deficiency could be possible risk factor for PPCM that affects pregnant women

Researchers have found a close link between selenium deficiency and Peripartum Cardiomyopathy (PPCM), a heart disease that affects pregnant women and recent mothers. The study of patients in Nigeria also showed that rural women were three times more likely to develop the disease, according to a doctoral dissertation at Umea University.

Studies show how speaking French could significantly reduce symptoms of Benign Essential Blepharospasm

A fascinating new study published in the latest edition of Movements Disorders (Vol.00 No.00, 2016) presents two patient case studies that demonstrate how speaking French as a second language can significantly reduce the symptoms of a life-limiting eye condition, Benign Essential Blepharospasm (BEB).

Novel iPad simulation app can instruct future nurses in monitoring babies and mothers during labor

Sheila Taylor leaned in to see the baby's heartbeat rhythm. She watched as the baby's heartbeat line fell without a corresponding spike showing the mother's uterus contracting down on it.

SFU scientists aim to develop new control system for most advanced bionic hands

A Canadian athlete's dream to one day "move" his fingers again after losing an arm in a workplace accident is now within grasp, thanks to a robotic arm prosthesis being developed at Simon Fraser University.

Little and often gives exercise benefits in Type 2 diabetes

Sedentary, overweight adults with Type 2 diabetes can improve their cardiometabolic profile by engaging in very brief but regular periods of light walking or resistance exercise, research suggests.

Scientists find way to control behaviour of cardiomyocytes using laser radiation

Scientists from MIPT's Laboratory of the Biophysics of Excitable Systems have discovered how to control the behaviour of heart muscle cells (cardiomyocytes) using laser radiation; this study will help scientists to better understand the mechanisms of the heart and could ultimately provide a method of treating arrhythmia. The paper has been published in the journal PLOS ONE.

Micra Transcatheter Pacing System approved to treat heart rhythm disorders

The U.S. Food and Drug Administration today approved the first pacemaker that does not require the use of wired leads to provide an electrical connection between the pulse-generating device and the heart. While the Micra Transcatheter Pacing System works like other pacemakers to regulate heart rate, the self-contained, inch-long device is implanted directly in the right ventricle chamber of the heart.

Transient contractions could be new target for therapeutic intervention in urinary bladder dysfunction

Researchers at the University of Vermont College of Medicine have made a discovery that helps explain how we know when to empty our bladders and may lead to new therapeutic interventions for bladder dysfunction.

UC Berkeley biologists discover potential target for unisex contraceptives

UC Berkeley biologists have discovered the switch that triggers the power kick sperm use to penetrate and fertilize a human egg, uncovering a possible source of male infertility but also a potential target for contraceptives that work in both men and women.

Long-term exercise may benefit Spinal Muscular Atrophy patients

Long-term exercise appears to be beneficial for Spinal Muscular Atrophy (SMA) like mice, suggesting a potential of active physiotherapy for patient care; according to a study published today in the Journal of Physiology.

Small, tablet-sized ultrasound devices may help midwives figure out C-section candidates

Midwives need more than fingers to figure out who the C-section candidates are. Small, tablet-sized ultrasound devices may be the key.

UTHealth researchers demonstrate new way to reduce preterm birth

Using nanoparticles to engineer a special drug, a team of researchers from McGovern Medical School at The University of Texas Health Science Center at Houston has demonstrated in pre-clinical trials a new way to both reduce preterm birth and avoid the risks of medication in pregnancy to unborn babies.

Study: Prior surgical abortion appears to increase risk of later preterm birth

Surgical methods used in a common form of abortion or to clear the womb after a spontaneous miscarriage appears to significantly increase the risk of a later preterm birth, say researchers at Thomas Jefferson University who analyzed 36 studies that enrolled more than 1 million women.

Study shows regular caffeine consumption does not lead to extra heartbeats

Contrary to current clinical belief, regular caffeine consumption does not lead to extra heartbeats, which, while common, can lead in rare cases to heart- or stroke-related morbidity and mortality, according to UC San Francisco researchers.

Findings offer potential new therapeutic target to boost strength of heart muscle contractions

Researchers at UT Southwestern Medical Center have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made from an RNA that was previously believed to be a blank or non-coding RNA, suggesting there may be many other small 'non-coding' segments that play important biological roles.
