Amsterdam, February 2, 2021 - The Canadian Neuromuscular Disease Registry (CNDR) was launched in 2010 to increase efficient patient access to cutting-edge research and clinical trials, to increase understanding of the natural history and epidemiology of neuromuscular disease across Canada, and to facilitate research collaboration. An assessment of CNDR's accomplishments, published in the Journal of Neuromuscular Diseases, found that it has been successful in securing funding and engaging the community over the past 10 years. With more than 4,000 enrolled patients, data from the registry have been used in over 125 research projects as of 2019, including clinical trial and research notifications, patient questionnaires, and data analyses around ...

The mesmerizing flow of a sidewinder moving obliquely across desert sands has captivated biologists for centuries and has been variously studied over the years, but questions remained about how the snakes produce their unique motion. Sidewinders are pit vipers, specifically rattlesnakes, native to the deserts of the southwestern United State and adjacent Mexico. Scientists had already described the microstructure of the skin on the ventral, or belly, surface of snakes. Many of the snakes studied, including all viper species, had distinctive rearward facing "microspicules" (micron-sized protrusions on scales) that had been interpreted in the context of reducing ...

PROVIDENCE, R.I. [Brown University] -- Studies have shown that nearly half of all medical students in the U.S. report symptoms of burnout, a long-term reaction to stress characterized by emotional exhaustion, cynicism and feelings of decreased personal accomplishment. Beyond the personal toll, the implications for aspiring and practicing physicians can be severe, from reduced quality of care to increased risk of patient safety incidents. According to a new study published on Tuesday, Feb. 2, in JAMA Network Open, students who identify as lesbian, gay or bisexual ...

Period poverty, a lack of access to menstrual hygiene products, and other unmet menstrual health needs can have far-reaching consequences for women and girls in the United States and globally. New research led by George Mason University's College of Health and Human Services found that more than 14% of college women experienced period poverty in the past year, and 10% experienced period poverty every month. Women who experienced period poverty every month (68%) or in the past year (61.2%) were more likely to experience moderate or severe depression than those who did not experience period poverty (43%). Dr. Jhumka Gupta, an associate professor at George Mason University was senior author of the study published in BMC Women's Health. ...

BOSTON - Amyloid-beta and tau are the two key abnormal protein deposits that accumulate in the brain during the development of Alzheimer's disease, and detecting their buildup at an early stage may allow clinicians to intervene before the condition has a chance to take hold. A team led by investigators at Massachusetts General Hospital (MGH) has now developed an automated method that can identify and track the development of harmful tau deposits in a patient's brain. The research, which is published in END ...

Nearly 11 percent of people admitted to an intensive care unit in Sweden between 2010 and 2018 received opioid prescriptions on a regular basis for at least six months and up to two years after discharge. That is according to a study by researchers at Karolinska Institutet published in Critical Care Medicine. The findings suggest some may become chronic opioid users despite a lack of evidence of the drugs' long-term effectiveness and risks linked to increased mortality. "We know that the sharp rise in opioid prescriptions in the U.S. has contributed to a deadly opioid crisis there," says first author Erik von Oelreich, PhD student in the Department of Physiology and ...

A decision-support tool that could be accessed via mobile devices may help clinicians in lower-resource settings avoid unnecessary antibiotic prescriptions for children with diarrhoea, a study published today in eLife shows. The preliminary findings suggest that incorporating real-time environmental, epidemiologic, and clinical data into an easy-to-access, electronic tool could help clinicians appropriately treat children with diarrhoea even when testing is not available. This could help avoid the overuse of antibiotics, which contributes to the emergence of drug-resistant bacteria. "Diarrhoea is a common condition among children ...

FRANKFURT. Chronic liver disease and even cirrhosis can go unnoticed for a long time because many patients have no symptoms: the liver suffers silently. When the body is no longer able to compensate for the liver's declining performance, the condition deteriorates dramatically in a very short time: tissue fluid collects in the abdomen (ascites), internal bleeding occurs in the oesophagus and elsewhere, and the brain is at risk of being poisoned by metabolic products. This acute decompensation of liver cirrhosis can develop into acute-on-chronic liver failure with inflammatory reactions throughout the body and failure of several organs. In the PREDICT study, led ...

BLOOMINGTON, Ind. - In Lily Tomlin's classic SNL comedy sketch, her telephone operator "Ernestine" famously delivers the punchline, "We don't care. We don't have to. We're the Phone Company." But new research finds that satisfied customers mean increased profits even for public utilities that don't face competition. Little is known about effect of customer satisfaction at utilities. As a result, utility managers are often unsure how much to invest in customer service - if anything at all. The issue also is of interest to regulators responsible for protecting consumers. The study, in ...

CORVALLIS, Ore. - One of birdwatching's most commonly held and colorfully named beliefs, the Patagonia Picnic Table Effect, is more a fun myth than a true phenomenon, Oregon State University research suggests. Owing its moniker to an Arizona rest area, the Patagonia Picnic Table Effect, often shortened to PPTE, has for decades been cited as a key driver of behavior, and rare-species-finding success, among participants in the multibillion-dollar recreational birding business - an industry that has gotten even stronger during a pandemic that's shut down so many other activities. But a study led by an OSU College of Science ...

Scientists and engineers at the University of Sydney and Microsoft Corporation have opened the next chapter in quantum technology with the invention of a single chip that can generate control signals for thousands of qubits, the building blocks of quantum computers. "To realise the potential of quantum computing, machines will need to operate thousands if not millions of qubits," said Professor David Reilly, a designer of the chip who holds a joint position with Microsoft and the University of Sydney. "The world's biggest quantum computers currently operate with just 50 or so qubits," he said. "This small scale is partly because of limits to the physical architecture that control the qubits." "Our ...

New research from the Okinawa Institute of Science and Technology Graduate University (OIST) has found a surprising randomness for how fluids choose their path around obstacles that depends on their spacing. This has important implications for a range of scenarios - from oil recovery and groundwater remediation, to understanding the movement of fluids through biological systems. The research was published in Physical Review Letters. Scientists from OIST's Micro/Bio/Nanofluidics Unit created a tiny set up comprised of two microscopic cylinders, each around the width of a human hair, placed side-by-side in a channel. This created a choice of three possible paths for a fluid to take past the pair of obstacles. A viscoelastic fluid, which is like that ...

OAK BROOK, Ill. - A technique that delivers high-intensity focused ultrasound to targeted tissue under MRI guidance effectively treats intermediate-risk prostate cancer with minimal side effects, according to a study published in Radiology. Prostate cancer is the most common cancer among men, aside from non-melanoma skin cancers. Common treatments to the entire gland, such as surgery and radiation therapy, are effective in eliminating the cancer, but they often leave patients with incontinence and sexual dysfunction. A class of treatments called focal therapy offers an alternative for some men with intermediate-risk disease that is still confined to the prostate. In focal therapy, the cancer is ablated, or destroyed, by either ...

By late summer 2020, the resurgence of COVID-19 in the United States was largely driven by adults between the ages of 20 and 49, a new study finds. The results indicate that in locations where novel highly transmissible SARS-CoV-2 lineages have not yet established, additional interventions among adults of these ages could bring resurgent COVID-19 epidemics under control and avert deaths. Following initial declines in the number of reported SARS-CoV-2 infections and deaths - a result largely attributed to non-pharmaceutical interventions - a resurgence in transmission of COVID-19 occurred in the United States and Europe beginning in August 2020. Understanding the age demographics that drove this is crucial. For example, between August ...

Laser particles are micrometre and nanometre lasers in the form of particles dispersible in aqueous solution, which have attracted considerable interest in the life sciences as a promising new optical probe. Laser particles emit highly bright light with extremely narrow spectral bandwidth. By transferring laser particles into live cells as shown in Figure 1, individual cells in a heterogeneous population can be tracked using each intracellular particle's specific spectral fingerprint as an optically readable barcode. However, laser particles emit directional light (Figure 2) and freely tumble inside living cells, their orientation varying randomly over time. Therefore optical readout of these labels results ...

Loess Plateau possesses a particular loess physiognomy with numerous ravines and slopes, and tableland is a typical landform in it. Together, the ununiform in both topographic undulation and land coverage compose the ununiform, complex underlying surface on Loess Plateau. This provides a special platform for research of turbulence above the complex underlying surface. As the front-edge problem encountered in the atmospheric boundary layer thesis, the turbulence research for complex underlying surface has drawn extensive attention recently. Local similarity has already proven that under certain condition, theories of turbulence based on the uniform underlying surface can also be applied to which for the ununiform underlying surface. ...

A team from Nanyang Technological University, Singapore (NTU Singapore) has developed a portable device that produces high-resolution 3D images of human skin within 10 minutes. The team said the portable skin mapping (imaging) device could be used to assess the severity of skin conditions, such as eczema and psoriasis. 3D skin mapping could be useful to clinicians, as most equipment used to assess skin conditions only provide 2D images of the skin surface. As the device also maps out the depth of the ridges and grooves of the skin at up to 2mm, it could also help with monitoring wound healing. The device presses a specially devised film onto the subject's skin to obtain an imprint of up to 5 by 5 centimetres, which is then ...

A satellite-based dataset generated by KAUST researchers has revealed the dynamics of dust storm formation and movements over the last decade in the Arabian Peninsula. Analysis of this long-term dataset reveals the connection between the occurrence of extreme dust events and regional atmospheric conditions, a finding that could help improve weather forecasting and air-quality models. Dust storms occur when strong winds lift tiny particles of sand into the atmosphere. These events often span several miles and can have an enormous impact on daily life, from damaging buildings and disrupting air traffic to triggering respiratory illnesses and other health problems. The Arabian Peninsula is a global hotspot of extreme dust events, with storms occurring ...

Residential gardens are a poor substitute for native bushland and increasing urbanisation is a growing threat when it comes to bees, Curtin University research has found. Published in 'Urban Ecosystems', the research looked at bee visits to flowers, which form pollination networks across different native bushland and home garden habitats. Lead author, Forrest Foundation Scholar Miss Kit Prendergast, from Curtin's School of Molecular and Life Sciences said the findings highlight the need to prevent destruction of remaining bushland and preserve native vegetation, in order to protect sustainable bee communities and their pollination services. "Our study involved spending hundreds of hours at 14 sites on the Swan Coastal Plain at Perth, Western Australia, ...

Researchers have shown how disposable face masks could be recycled to make roads, in a circular economy solution to pandemic-generated waste. Their study shows that using the recycled face mask material to make just one kilometre of a two-lane road would use up about 3 million masks, preventing 93 tonnes of waste from going to landfill. Developed by researchers at RMIT University in Melbourne, Australia, the new road-making material is a mix of shredded single-use face masks and processed building rubble designed to meet civil engineering safety standards. ...

Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from Belgium take a step in the development of genome editing technology. Currently it is possible to deliver genetic material of different sizes and structures to organs and tissues. This is the key to eliminating DNA defects and treating more patients. The project is guided by Professor Gleb Sukhorukov and supported by the Russian Science Foundation. Research results were published in Particle & Particle Systems Characterization journal. An international research group developed a polymer ...

Semiconducting 2D alloys could be key to overcoming the technical limitations of modern electronics. Although 2D Si-Ge alloys would have interesting properties for this purpose, they were only predicted theoretically. Now, scientists from Japan Advanced Institute of Science and Technology have realized the first experimental demonstration. They have also shown that the Si to Ge ratio can be adjusted to fine tune the electronic properties of the alloys, paving the way for novel applications. Alloys--materials composed of a combination of different elements or compounds--have played a crucial role in the technological development of humans since the Bronze Age. Today, ...
