UT Southwestern is one of the top enrolling centers of the 50 sites in the United States. The Optimizer System is an implantable pulse generator that delivers electrical impulses to the heart for treatment of moderate to severe heart failure. Unlike other heart-failure devices, the Optimizer works by strengthening the pumping force of the heart. The Optimizer System modulates the strength of the heart's contractions rather than controls its rhythm.
"The Optimizer could benefit up to two-thirds of advanced heart-failure patients who may not qualify for other kinds of therapy," said Dr. Jose Joglar, co-investigator of the study and associate professor of medicine in UT Southwestern's Heart, Lung and Vascular Center.
Heart failure is a disease that afflicts more than five million Americans and an estimated 15 million patients worldwide and is one of the most common causes of hospitalization. In patients with heart failure, the heart muscle itself is too weak or damaged to pump enough blood through the body. Medications such as beta blockers and other device-based therapies are typically used to treat patients with heart failure. But not all patients respond to these initial therapies.
"In spite of the advances made over the last 15 years, heart failure remains a common cause of death or disability," said Dr. Owen Obel, cardiologist and assistant professor of internal medicine. "This novel therapy stimulates the heart as it is beating. This makes each heart beat stronger for the time that the device is activated. It could really improve the quality of life for the many thousands of people worldwide who suffer from severe heart-failure symptoms."
Dr. Obel, who heads the electrophysiology and pacing laboratory at the Dallas Veteran Affairs Medical Center, is co-investigator for the UT Southwestern trial and has implanted the devices in the five patients who were selected to the study group receiving the implant. Three additional patients are due to receive the device soon. The study will continue to enroll participants until the end of the year.Patients who qualify for the Optimizer System undergo a surgical procedure similar to putting in a pacemaker. Typically, the surgery takes about four to five hours and requires three leads to be implanted into the heart itself.
"We've been enrolling patients for more than a year now and so far our experiences have been good," said Dr. Joglar.

The UT Southwestern Heart, Lung and Vascular Center is a collaborative effort between UT Southwestern faculty and community physicians who unite to bring their clinical and surgical expertise to patients needing cardiac, pulmonary or vascular care. Seamless, individualized care is available for adult congenital heart disease, cardiac imaging, cardiovascular and thoracic surgery, electrophysiology, general cardiology, heart failure, heart and lung transplant, interventional cardiology, interventional radiology, lung transplant pulmonology, mechanical circulatory assistance, preventive cardiology, pulmonary hypertension, and vascular and endovascular surgery.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
