Russian scientists demonstrate ion implantation advantages for the use of silicon in optoelectronics
Silicon is the main material in electronic engineering. All information and computing technologies that play a key role in modern civilization are based on silicon: computers, communications, astronautics, biomedicine, robotics and much more.
A study about grazing exclusion using fences on the Tibetan Plateau(TP) by a team of researchers from China (Dr. Jian Sun's research team at Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences), Australia and Japan recently published in Science Bulletin, and commented in the Editors' choice column of Science.
A widely available and inexpensive drug that is used to ease the symptoms of indigestion may prove a worthy contender for treating COVID-19 infection in those whose disease doesn't require admission to hospital, suggest the findings of a small case series, published online in the journal Gut.
The effects were felt within 24 to 48 hours of taking famotidine, and a rigorous clinical trial is now warranted to see if the drug could be an effective treatment for COVID-19, say the researchers.
A patient-reported symptom tracking method used for patients with cancer has now been adapted for patients with COVID-19. Investigating the effect of famotidine, a potential treatment for COVID-19, on non-hospitalized patients with COVID-19, clinicians at Northwell Health and cancer researchers at Cold Spring Harbor Laboratory (CSHL) developed the method to use in addition to laboratory tests. This outpatient approach addresses the need to care for the majority of COVID-19 patients who do not require hospitalization.
King's College London researchers have called for the immediate use of additional COVID-19 symptoms to detect new cases, reduce infections and save lives.
In a letter published in The Lancet, the team discussed how loss of taste and smell - anosmia - should form part of screening measures for the virus.
New research provides a roadmap to help the millions of older Britons struggling with 'shopping lists' of medication, as fears grow that the current coronavirus lockdown could be further isolating the most vulnerable.
With the over-70s and people with existing medical conditions being encouraged to 'shield' or self-isolate in lockdown as much as possible, there are concerns many could be avoiding seeking help from GPs and pharmacies in managing multiple medications, known as 'polypharmacy'.
COVID-19 restrictions in France should be lifted with caution because of the high risk of a second wave of infection, reports a new study, published in Frontiers in Medicine, which confirms the lockdown restrictions were successful in reducing the spread of this virus.
June 5, 2020-- A new paper published online in the Annals of the American Thoracic Society examines ventilation and medication strategies that can help avoid psychological trauma for severe COVID-19 survivors treated for acute respiratory distress syndrome (ARDS) with mechanical ventilation.
At a glance:
Fruit fly study finds death by sleep deprivation is preceded by the accumulation of molecules known as reactive oxidative species (ROS) in the gut
Neutralizing ROS in the gut allows severely sleep-deprived fruit flies to have normal lifespans
Buildup of ROS in the gut due to insufficient sleep occurs across species
Findings potentially inform future efforts to counteract the harmful effects of sleep deprivation in humans
Cancer cells can turn on error-prone DNA copy pathways to adapt to cancer treatment, a breakthrough study published in the journal Science has revealed. Bacteria use the same process, termed stress-induced mutagenesis, to develop antibiotic resistance.
The cells of the human body are constantly dividing, and each time need to copy a three billion-letter DNA code with high precision to ensure cell survival. The same is not true for cancers, researchers have discovered.
In less than three decades, most of Southeast Asia's peatlands have been wholly or partially deforested, drained, and dried out. This has released carbon that accumulated over thousands of years from dead plant matter, and has led to rampant wildfires that spew air pollution and greenhouse gases into the atmosphere.
Osaka, Japan and Houston, Texas, USA - For a sperm produced in the testis of a man to fertilize a woman's egg, the sperm must first mature in a man's epididymis. Now, an international team of researchers has identified a chain of events in which a protein secreted by the testis travels in the luminal fluid, binds to a receptor on the epididymis to induce its differentiation and secretion of a second protein that matures the sperm and enables each sperm to be motile in females.
Do you have what is known as problematic alcohol use? Then statistically you will also be particularly genetically predisposed to develop e.g. depression and insomnia. And to become dependent on drugs and tobacco. This is shown by a new international study in which researchers from iPSYCH are involved.
The researchers have looked at the role played by genes when a person year after year drinks such large amounts of alcohol, that he or she ends up experiencing serious psychological, social and health damage.
The international study "Resistance to targeted therapies as a multifactorial, gradual adaptation to inhibitor specific selective pressures", recently published in the scientific journal Nature Communications, has taken a further step in the development of new therapeutic strategies to treat lung cancer.
This study, the result of more than three years of research, was conducted at the Moffitt Cancer Center in Tampa (Florida, USA) and makes progress toward the evolution of resistance to different tumor inhibitors. Scientist Robert Vander Velde is the main author of it.
New modern physical school spaces require open communication between stakeholders in order to be transformed into meaningful learning environments, a new study from the University of Eastern Finland shows. Pre-existing pedagogies or good practices as such cannot be transferred from one space to another.
