Washington: A study involving 800 children has shown the inclusion of sugar in their diet and early interruption of breastfeeding to be the main factors that contribute to the appearance of dental caries by age 2. The study was published in the journal 'Community Dentistry and Oral Epidemiology'. The World Health Organization (WHO) recommends exclusive breastfeeding for the first six months of life, followed by solid food together with continued on-demand breastfeeding up to 2 [...]

Analysis of damaged brain samples revealed that astrocytes, which are brain cells that sustain neuronal metabolism, were particularly likely to be infected with SARS-CoV-2 Washington: Daniel Martins-de-Souza and colleagues used MRI to compare brain structure in 81 study participants recovering from a mild COVID-19 infection and 81 healthy individuals. The authors found that the former group exhibited reduced cortical thickness, which was correlated with cognitive impairments and symptoms such [...]

A telescope with ' Giant ' in its name, got to be something. We are talking about The Giant Magellan Telescope, which is the largest Gregorian optical infrared telescope ever engineered, providing the widest field of view of the Universe with seven of the world’s largest mirrors. The telescope is under construction in Las Campanas Peak at the southern edge of Chile’s Atacama Desert. While the Hubble Telescope has always introduced us to some amazing pictures from the [...]

Sau Paulo: In laboratory tests, the researchers used a drug to inhibit the interaction between the molecules, reducing viral replication by 15 to 20 per cent. They anticipate that their findings will aid in the development of COVID-19 treatments. " PCNA (proliferating cell nuclear antigen), a human protein, interacts with SARS-CoV-2 protein M [matrix], one of the molecules that make up the virus's membrane and give it shape." "The discovery itself demonstrates one of the [...]

According to a recent study, SARS-CoV-2, the virus that causes COVID-19, can infect a person for more than 200 days in an atypical case. Washington: A new study has detected that SARS-CoV-2, the virus that causes COVID-19, can infect a person for more than 200 days in an atypical case. The study has been published in the 'Frontiers in Medicine Journal'. The atypical case of infection by SARS-CoV-2 was part of a study involving 38 Brazilian patients followed on a weekly basis [...]

Sao Paulo: A new study has found that the dangerous combination of weak muscles and abdominal fat can lead to a significant loss of gait speed in older people. The findings of the study were published in the journal 'Age and Ageing'. The study was conducted by researchers at the Federal University of Sao Carlos (UFSCar) in the state of Sao Paulo, Brazil, in partnership with colleagues at University College London (UCL) in the UK. A slower gait is a natural outcome of the ageing [...]

According to the World Health Organization (WHO), about 1 per cent of the world population over 65 had Parkinson's in 2019. Brasilia: Transcranial direct current stimulation (tDCS) can increase the benefits of aerobic exercise and improve the gait of patients with Parkinson's disease immediately after a session. Step time variability decreases, reaction time shortens, and executive control of gait is enhanced. These were the main findings of a randomized, double-blinded, [...]

A recent study found that remotely supervised workout sessions proved to be more effective than face-to-face exercise classes during the COVID-19 pandemic. Washington: Remotely supervised workout sessions were found to be more effective than face-to-face exercise classes during the COVID-19 pandemic, suggested a new study. The findings of the study appeared in the journal 'Psychiatry Research'. Researchers at the University of Sao Paulo (USP) in Brazil investigated the effects of [...]

Brasilia: A research group at Sao Paulo State University (UNESP) has analyzed how Candida albicans fungi and Staphylococcus aureus bacteria influence gene expression and tumour cell survival. An in vitro study conducted by researchers at UNESP in Araraquara, Brazil, shows how fungi and bacteria can activate genes associated with head and neck tumours, as the metabolism of biofilms (communities in which these microorganisms self-organize in a structured and coordinated manner) stimulate tumour [...]
