Technique Distinguishes Between Types of Oral Bone Lesion Based on MRI Scan Image Texture
Publicado em 16 de fevereiro de 2023
Ameloblastomas and odontogenic keratocysts are benign lesions of the maxillo-mandibular region with different biological characteristics. The former is often aggressive, forming a large tumor and growing into the jawbone. The latter are cysts that can be managed and treated in various ways.
However, they have practically identical morphological characteristics and are extremely difficult to distinguish using conventional imaging techniques such as x-rays, MRI scans, and CT scans, making [...]

Study Reveals Main Target of SARS-CoV-2 in Brain and Describes Effects of Virus on Nervous System
Publicado em 03 outubro 2022A Brazilian study published in the journal PNAS describes some of the effects infection by SARS-CoV-2 can have on the central nervous system. A preliminary version (not yet peer-reviewed) posted in 2020 was one of the first to show that the virus that causes COVID-19 can infect brain cells, especially astrocytes. It also broke new ground by describing alterations in the structure of the cortex, the most neuron-rich brain region, even in cases of mild COVID-19. The cerebral cortex is the [...]ver notícia -
Lung ultrasound helps predict covid-19 patient outcomes
Publicado em 16 fevereiro 2021Lung ultrasound, considered a simple method for diagnosing lung disease, can also help predict the clinical progression of severe COVID-19 patients, according to a study conducted at the University of São Paulo’s Medical School (FM-USP) in Brazil. The principal investigator for the study was Heraldo Possolo de Souza, a professor at FM-USP and an attending physician at its teaching and general hospital, Hospital das Clínicas (HC). The researchers applied an ultrasound [...]ver notícia -
Virtual Reality Applied to Rehabilitation for Stroke and Neurodegenerative Disease Patients
Publicado em 15 dezembro 2020Virtual reality (VR)-based rehabilitation programs are becoming an important complement to conventional motor therapy for stroke patients and individuals with neurodegenerative diseases. Immersion in virtual environments stimulates several sensory systems, especially sight and hearing, and intensifies central nervous system information input and output. “The technology is expected to increase brain connectivity by stimulating the new neural connections needed to repair the losses caused [...]ver notícia
