Novel computer simulation method can accelerate COVID-19 drug discovery
Publicado em 13 dezembro 2021
An article reporting the results of the study is published in the Journal of Biomolecular Structure and Dynamics. The authors explain that the outer protein layer of SARS-CoV-2 is rich in the amino acid cysteine, which must be active and intact for the virus to remain viable, and is therefore referred to as its main protease (Mpro). Proteases are enzymes that cleave the peptide bonds between amino acids and proteins and break down polyproteins (protein chains) into smaller proteins, which in [...]

Biosensors help with non-invasive diagnosis of diseases
Publicado emA study conducted at the University of São Paulo's São Carlos Physics Institute (IFSC-USP) in Brazil compared the performances of two types of self-assembled monolayers, one consisting of mercaptoacetic acid (MAA) in water and ethanol, and another of 11-mercaptoundecanoic acid (11-MUA) in ethanol. The respective films were evaluated in terms of their capacity to produce sensors for detection of the gene PCA3, which is specific to prostate cancer cells. "We showed that [...]ver notícia -
VR applied to rehabilitation for stroke patients
Publicado em 16 dezembro 2020A study performed at one of the Research Centers supported by FAPESP resulted in development of a novel rehabilitation device. The article was recognized as outstanding by the 20th International Conference on Computational Science and its Applications. Virtual reality-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 [...]ver notícia -
Wearable sensors analyze substances present in sweat
Publicado em 18 agosto 2020A wearable sensor printed on microbial nanocellulose, a natural polymer, has been created in Brazil by researchers at the University of São Paulo (USP) in São Carlos in collaboration with colleagues at São Paulo State University (UNESP) in Araraquara, the University of Araraquara (UNIARA), the University of Campinas (UNICAMP), and the Brazilian National Nanotechnology Laboratory (LNNano). The skin-adherent sensor is an improved substitute for [...]ver notícia -
Detecting biomarker of early-stage multiple sclerosis
Publicado em 27 abril 2020Diagnostic strategy developed by Brazilian researchers can also be used to distinguish MS from neuromyelitis optica, another demyelinating disorder. The two diseases have similar symptoms but must be treated differently. Researchers at the Federal University of São Carlos (UFSCar) in Sorocaba (state of São Paulo, Brazil) have developed a technique to diagnose early-stage multiple sclerosis, a disease of the central nervous system, and distinguish it from neuromyelitis optica, a [...]ver notícia
