Spina Bifida is a birth defect where there is an incomplete closure of the backbone and the coverings around the spinal cord. It affects more than 4,000 children born each year in the United States and is associated with hydrocephalus (fluid in the brain), developmental delay, lifelong disability and death. Spina Bifida is also associated with a need for shunt placement. In-utero surgery has been shown to reduce the need for shunting of hydrocephalus and to improve a child's ability to walk.
Researchers tested two types of sutures -- poliglecaprone 25 (monocryl® suture) and polyglactin 910 (vicryl® suture). Monocryl is an absorbable, single filament suture with low tissue reactivity which dissolves slowly and loses strength. Vicryl is an absorbable, braided suture with low tissue reactivity which dissolves quickly but maintains strength.
Most spiral galaxies like the Milky Way have a supermassive black hole at the center. But this spiral galaxy, named RX J1140.1+0307, is centered on a black hole with one of the lowest masses ever found in a galactic core.
Sprint has acquired a 33 percent stake in Jay Z's music streaming service Tidal, the two companies announced today. From a report: A source familiar with the matter tells Billboard that the purchase was for $200 million and that Jay and each of the company's two dozen artist-owners will remain part owners. As part of the deal, Tidal will become available to Sprint's 45 million retail customers, while the companies will partner for exclusives from its artists, according to a press release.
A clinical trial studying the use of Verapamil (a drug currently in use for cardiovascular disease and cluster headache) in alleviating chronic rhinosinusitis (CRS) with nasal polyps revealed significant improvement in the symptoms of this subset of patients.
Whether it's electric automobiles, renewable energy, carbon tax or sustainable consumption, sustainable development requires strategies that meet people's needs without harming the environment. Before such strategies are implemented, their potential impact on environment, economy, and society needs to be tested. These tests can be conducted with the help of computer models that depict future demographic and economic development and that examine the interplay between industry and the climate. But computer models play a significant role in environmental policy, but offer only a partial picture of the industrial system, say experts.
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequisite for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
Today, a stroke usually leads to permanent disability – but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation. Researchers have taken a step in that direction by showing that some neurons transplanted into the brains of stroke-injured rats were incorporated and responded correctly when the rat’s muzzle and paws were touched.
Liver metastases are formed from cancer cells that have originated in other organs and migrated to the liver via the bloodstream. Colorectal cancer (cancer of the colon/rectum) can be successfully treated by surgical resection of the metastases in combination with chemotherapy. Now a research team has identified a new biomarker that allows better prediction of survival following surgical removal of the metastases, as well as a change in the clinical significance of the biomarker following chemotherapy.
A piece of research has resolved the tautomeric equilibrium of a model system of great biological interest. The work was made possible by setting up a piece of equipment that they themselves developed to characterize sets of molecules in a very accurate way. The research has thus put an end to the controversy that existed between the prior experiments and theoretical calculations that yielded contradictory and inconclusive results.
Germline cells are the only cells that develop into eggs or sperm, while somatic cells develop into the body. Progenitors of the germline, known as primordial germ cells (PGCs), differentiate into eggs or sperm after embryonic development. The expression of a select group of genes occurs in the PGCs of a number of different animal groups, indicating a possible conserved mechanism of germline gene activation. Until now, it has been unclear if Ovo was needed for normal germline development of the fruit fly, or whether the related mouse protein played a similar role in mouse embryos.
