Low-Level Laser Therapy Emerges as Most Effective Treatment for Tinnitus
Publicado em 22 junho 2023
Low-level laser therapy proves to be the most effective treatment for tinnitus, a widespread symptom affecting around 750 million people worldwide, as revealed by a study conducted by Brazilian scientists from the Optics and Photonics Research Center (CEPOF). The research indicates that laser therapy, including laser acupuncture, significantly helps alleviate tinnitus symptoms through anti-inflammatory action and promoting inner ear cell proliferation and blood flow.

Brazilian fossil provides earliest evidence of evolutionary trait that enabled dinosaurs to become giants
Publicado em 21 junho 2023Bone cavities called air sacs appeared in the ancestors of long-necked dinosaurs about 225 million years ago, according to the analysis of a specimen found in Rio Grande do Sul state, South Brazil. The study also shows that air sacs did not evolve as linearly as scientists believe (credit: Márcio L. Castro) The missing link has just been found between the earliest dinosaurs, whose size ranged from a few centimeters to at most 3 meters in length, and more recent giants that could be [...]ver notícia -
Study Finds No Difference in Muscle Growth Between High-Load and Low-Load Resistance Training
Publicado em 24 maio 2023A recent study conducted at the State University of Campinas (UNICAMP) in São Paulo, Brazil, has shed light on the question of which type of resistance training promotes greater muscle growth: high load with fewer repetitions or low load with more repetitions. Surprisingly, the study found that it makes no difference. The eight-week study involved 18 volunteers who were divided into two groups following different training protocols. One group performed high-load (HL) exercises with [...]ver notícia -
In resistance training, focusing on load or number of repetitions leads to same muscle growth
Publicado em 24 maio 2023A study by researchers at the State University of Campinas showed that although the two types of training produce similar metabolic stress, muscle activation is different. Peer-Reviewed Publication FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO Which kind of resistance training promotes more muscle growth: low load with many repetitions or high load with fewer repetitions? According to a study conducted at the State University of Campinas [...]ver notícia -
Scientists create model to predict depression and anxiety using artificial intelligence and social media
Publicado em 10 abril 2023Researchers at the University of São Paulo (USP) in Brazil are using artificial intelligence (AI) and Twitter, one of the world’s largest social media platforms, to try to create anxiety and depression prediction models that could in future provide signs of these disorders before clinical diagnosis. The study is reported in an article published in the journal Language Resources and Evaluation. Construction of a database, called SetembroBR, was the first step in the study. The [...]ver notícia -
Burning sensation from pepper, can block chronic pain
Publicado emPain afflicts at least 1.5 billion people worldwide, and despite the availability of various painkilling drugs, not all forms of pain are treatable. Moreover, pain medications can have side-effects such as dependence and tolerance, especially in the case of morphine and other opioids. In search of novel painkillers, researchers at Butantan Institute’s Special Pain and Signaling Laboratory (LEDS) in São Paulo, Brazil, studied TRPV1, a sensory neuron receptor that captures noxious [...]ver notícia -
COVID-19 virus can be detected in tears
Publicado em 16 fevereiro 2023Research led by scientists at the University of São Paulo (USP) in Brazil has found that the coronavirus that causes COVID-19 can be detected in tears collected by swabbing. A swab is an absorbent cotton pad on a flexible rod used to clean wounds, apply medication and take specimens. The researchers analyzed samples from patients diagnosed with the disease by conventional methods and admitted to the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC) run by the Bauru Dental [...]ver notícia -

Low-cost sensor detects heavy metals in sweat
Publicado em 23 janeiro 2023Heavy metals such as lead and cadmium are present in batteries, cosmetics, food and other things that are part of everyday life. They are toxic when they accumulate in the human organism, potentially causing several health problems, but detecting them in body fluids requires expensive equipment and a controlled laboratory environment. Researchers at the University of São Paulo (USP) in Brazil have now developed a portable sensor made of simple materials to detect heavy metals in [...]ver notícia -
Exotic Ice Helps Explains Uranus, Neptune Magnetic Mysteries
Publicado em 22 janeiro 2023Ordinary everyday ice, like the ice produced by a fridge, is known to scientists as hexagonal ice (ice Ih), and is not the only crystalline phase of water. More than 20 different phases are possible. One of them, called “superionic ice” or “ice XVIII”, is of particular interest, among other reasons, because it is thought to make up a large part of Neptune and Uranus, planets frequently referred to as “ice giants”. In the superionic crystalline phase, [...]ver notícia
