The use of platelet-rich plasma therapy can reduce the risk of a second meniscus failure after operation but does not seem to protect patients who have had surgery to repair an anterior cruciate ligament, according to research presented at the Annual Meeting of the American Orthopedic Society of Sports Medicine.
Theodoros Zanos, PhD, head of the Neural & Data Science Lab & assistant professor at the Institute of Bioelectronic Medicine, The Feinstein Institutes for Medical Research, and his collaborators, discovered how the vagus nerve relays signals from the periphery to the brain to help regulate glucose, potentially uncovering a new way to measure blood glucose levels. This finding progresses research into future bioelectronic medicine treatments and diagnostics for metabolic syndrome and diabetes.
Death metal band logos often have a spiky look while romance novel titles often have a swirly script. The jaggedness or curviness of a font can be used to express an emotional tone. A Dartmouth study published in the Proceedings of the Royal Society B finds that sounds, shapes, speech and body movements convey emotional arousal the same way across the senses. The findings explain why nearly anything can have an emotional tone, including art, architecture and music.
RICHLAND, Wash. July 10, 2019 - The goal of the research, published July 11 in the journal Nature, was to engineer artificial proteins to self-assemble on a crystal surface by creating an exact match between the pattern of amino acids in the protein and the atoms of the crystal. The ability to program these interactions could enable the design of new biomimetic materials with customized colors, chemical reactivity or mechanical properties, or to serve as scaffolds for nano-scale filters, solar cells or electronic circuits.
Questions commonly used to explore the "Big Five" personality traits--Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism--generally fail to measure the intended personality traits in developing countries, according to a new study. This is because measurement of these traits relies on surveys typically applied to White Educated Industrialized Rich and Democratic (WEIRD) populations. The Big Five personality trait model is used to inform issues related to crime, employment, and wages in high-income countries.
A study of 86 patients reveals how drugs used for anesthesia can induce life-threatening anaphylaxis (a dangerous type of allergic reaction) through an alternative immune pathway. Their findings help to answer a conundrum in allergy research - why the classic explanation of anaphylaxis does not appear in all patients - and could guide the development of diagnostics to lower the risk of anaphylaxis during anesthesia.
Peptides, one of the fundamental building blocks of life, can be formed from the primitive precursors of amino acids under conditions similar to those expected on the primordial Earth, finds a new UCL study.
The findings, published in Nature, could be a missing piece of the puzzle of how life first formed.
Anaphylactic shock, an exacerbated allergic reaction that can prove fatal, is sometimes caused by the use of drugs during surgery. In most of these extreme reactions, evidence can be provided that patients have anti-drug antibodies of the IgE class. In 10 to 20% of anaphylactic cases evidence for the involvement of anti-drug IgE is lacking. Anti-drug IgE enable activation of mast cells and basophils that release histamine, a potent mediator involved in anaphylaxis.

Terahertz (THz) radiation is a bit like a treasure chest that resists being opened fully. Residing in the electromagnetic spectrum between the infrared and microwave regions, THz radiation combines a range of properties that are ideal with a view to applications. It provides a window to unique spectroscopic information about molecules and solids, it can penetrate non-conducting materials such as textiles and biological tissue, and it does so without ionising -- and hence damaging -- the object, or subject, under study.
An early assessment reveals that a newly approved drug to treat migraines does not seem effective among patients who suffer from high-frequency migraines.
The findings will be presented this week during the 61st annual scientific meeting of the American Headache Society in Philadelphia.
Clinicians at OHSU in Portland, Oregon, conducted a retrospective chart review of 28 patients who were prescribed 70 miligrams of Erenumbab per month for three months beginning in June of 2018. Each of the patients reported 25 or more headache days per month when they began the treatment.
It's estimated that as much as two-thirds of energy consumed in the U.S. each year is wasted as heat. Take for example, car engines, laptop computers, cell phones, even refrigerators, that heat up with overuse.
Imagine if you could capture the heat they generate and turn it into more energy.
The queen problem is a mathematical task, which already had the great mathematician Carl Friedrich Gauss occupied, but for which he surprisingly did not find the right solution. The challenge here is how to arrange eight queens on a classical chess board with 8 x 8 squares so that no two queens threaten each other. Mathematically, it is relatively easy to determine that there are 92 different ways to arrange the queens. On a chess board with 25 x 25 squares there are already more than 2 billion possibilities. The calculation of this number alone took a total of 53 years of CPU time.
Individually, ants have only so much strength and intelligence. However, as a colony, they can use complex strategies to complete sophisticated tasks and evade larger predators.
Research for the benefit of food security: A new line of barley achieves good crop yields even under poor environmental conditions. It has been bred by a research team from Martin Luther University Halle-Wittenberg (MLU), which crossed a common variety with various types of wild barley. The researchers then planted the new lines of barley in five very different locations around the world, observed the growth of the plants and analysed their genetic make-up.
