3-D-printing allows extremely small and complex structures to be made even in small series. A method developed at the KIT for the first time allows glass to be used for this technique. The use of glass in 3-D-printing opens up manifold new applications in production and research, such as optics, data transmission, and biotechnology. The process is published in Nature and presented at the Hanover Fair.
DGIST's research team develops technology which is 20 times faster than the existing biosensors using micromagnetic pattern of spider web.The technology can be used for early diagnosis and recurrence diagnosis of diseases such as cancer.
New Stanford study describes a model for designing novel materials used in electrical storage devices, such as car batteries and capacitors. This approach may dramatically accelerate discovery of new materials that provide cheap and efficient ways to store energy.
The most comprehensive study on the bones of Homo floresiensis, a species of tiny human discovered on the Indonesian island of Flores in 2003, has found that they most likely evolved from an ancestor in Africa and not from Homo erectus as has been widely believed.
People who are addicted to opioids and receiving their medical care in a general health care setting were more than 10 times as likely to die during a four-year period than people without substance abuse problems, UCLA researchers have found.
Hospitals nationwide are seeking ways to use price transparency -- displaying the price of lab tests at the time when doctors are placing the order -- to nudge doctors to consider whether the benefits are worth the cost. But, results of a new study show that simply displaying the Medicare allowable fees did not have an overall impact on how clinicians ordered these tests. The results are published today in JAMA Internal Medicine and presented at the Society of General Internal Medicine annual meeting in Washington, DC.
Using the gene-editing tool CRISPR/Cas9, researchers at University of California San Diego School of Medicine and Shiley Eye Institute at UC San Diego Health, with colleagues in China, have reprogrammed mutated rod photoreceptors to become functioning cone photoreceptors, reversing cellular degeneration and restoring visual function in two mouse models of retinitis pigmentosa.
The World Hepatitis Alliance today welcomes the publication of the first-ever Global Hepatitis Report by the World Health Organization (WHO), which includes new data on the prevalence and global burden of viral hepatitis.
Many companies want to know how the creation of their products affects the environment. Scientists at Stanford, the University of Minnesota and Unilever have found a way to better predict and quantify environmental impacts.
Results from a study presented today found that the incidence of HEV RNA in asymptomatic blood donors from Germany is higher than previously reported. The study, presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, showed that 0.11 percent of donations tested were HEV RNA positive and that one of the asymptomatic HEV RNA positive donors had previously donated HEV RNA positive blood products, which were then transfused into nine immunocompromised patients.
A new European study presented today demonstrated that patients with chronic HCV and severe liver damage, taken off the liver transplant list as a result of successful DAA therapy, had a favorable outcome over a year later. The study, presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, showed that 26.7 percent of patients could be removed from the waiting list due to clinical improvement.
A large epidemiological study presented today found that a diet high in animal protein was associated with a higher risk of non-alcoholic fatty liver disease (NAFLD), a condition in which fat builds up in the liver. These findings from The Rotterdam Study, presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, also showed that fructose consumption per se might not be as harmful as previously assumed.
A study presented today found that fecal transplantation of bacteria from one healthy donor into patients that suffer from hepatic encephalopathy, is safe and improves cognitive function compared with standard of care treatment for the condition. Presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, the study results also demonstrated that the number of hospitalizations following fecal transplantation plus antibiotics was two, compared to the standard of care arm, which was 11.
A study presented today that evaluated an investigational dosage of once-daily ledipasvir 45 mg/sofosbuvir 200 mg (LDV/SOF) in children aged six to 11 years infected with HCV, found that 99 percent of children had undetectable levels of HCV-RNA 12 weeks after treatment. The study, presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, showed that the fixed-dose combination of LDV/SOF was well-tolerated, and no patients experienced serious adverse events related to the study drug.
Study results presented today demonstrate that the oral, once-daily treatment regimen of glecaprevir/pibrentasvir resulted in 95 percent sustained virologic response rates 12 weeks post treatment in patients with HCV genotype 3. In the ENDURANCE-3 study, presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, patients infected with HCV genotype 3 without cirrhosis and who had no previous treatment history were treated with the new regimen for eight or 12 weeks, which was well tolerated.
Results from the CheckMate 040 study presented today found that nivolumab produces durable responses with long-term survival rates, regardless of whether or not patients were infected with Hepatitis B or C. Interim results from the study, presented at The International Liver Congress 2017 in Amsterdam, The Netherlands, showed that the overall objective response rate (ORR) was 14.5 percent and ORR by investigator assessment was 19.3 percent in sorafenib-experienced patients in the dose expansion phase of CheckMate 040.
Analysis reveals that female researchers are over-represented on the social-media site and that mathematicians and life scientists are less likely to use it.
