Estudo identifica mecanismo que pode estar envolvido com depressão e perda de memória na covid e pós-covid
Pesquisadores de USP, Unicamp e UFRJ mostraram que o Sars-Cov-2 infecta astrócitos – tipo de célula cerebral – e isso pode estar ligado a distúrbios neurológicos.

The value of ‘wasting time’ on deep thinking is often overlooked in a scientific ecosystem increasingly tainted by Wall Street’s productivity mindset.

Last night, we honored our 5 laureates of the 2024 @FondationLOreal-@UNESCO#ForWomenInScience International Awards - a ceremony marked by stories of resilience & empowerment.
Thank you to all guests who've attended #FWIS2024, in person or online, to make it a memorable evening!
What can we do to prevent #dementia?
Science shows us that modifying 12 major risk factors might prevent or delay up to 40% of dementias.
These factors are: less education (7%), hypertension (2%), hearing impairment (8%), smoking (5%), depression (4%), physical inactivity (2%), low social interaction (4%), direct brain injury (3%), among others (check the figure below).
It is never too early or too late for dementia prevention.
-Early-life (younger than 45 years) risks, such as less education, affect cognitive reserve; you increase blood circulation in the brain by learning and thinking, improving brain resistance to damage.
-Midlife (45–65 years) and later life (older than 65 years) risk factors influence cognitive reserve and trigger neuropathological developments—inducing neuroinflammation and neuronal death.
Culture, poverty, and inequality are key drivers of the need for change. Individuals who are most deprived need these changes the most and will derive the highest benefit.
Policy should prioritise childhood education for all.
Public health initiatives minimizing head injury and
decreasing harmful alcohol drinking could potentially
reduce young-onset and later-life dementia.
Be ambitious about prevention
- Attain a high level of education to increase and maintain cognitive reserve.
-Hearing aids reduce substantially the excess risk of dementia from hearing loss.
- Sustained exercise in any moment of life protects from dementia (perhaps through decreasing obesity, diabetes, and cardiovascular risk).
- Prevent head injury.
- Limit alcohol use: more than 21 units weekly increase the risk of dementia.

Today is #idwgs2024 ! 👩🏾🔬👩🏿🔬
At OWSD we celebrate #womeninscience every day, but especially today, we shine a light on our nearly 700 fellows and alumnae, 70 award winners, more than 9,800 members and 54 National Chapters. Women who are changing their communities and the world! 🌍
New microscopy technology enables nanoscale imaging of centimetre-scale tissues, making it possible to image the entire expanded mouse brain at cellular and subcellular resolution. #ReviewedPreprint https://t.co/7D3JyPGvWo
A special thank you to Victor Corasolla, Flávio Protásio, Clarissa Yasuda (@clayasuda), Marcelo Mori (@MoriLabe ), Thiago Cunha (@tmcunha10 ) and Daniel Martins-de-Souza (@neuroproteomics).
I am glad to share that I have been awarded the prestigious "Honra ao Mérito pelo Prêmio DESTAQUE DO ANO NO ARTIGO CIENTÍFICO DO IB ‘JOÃO PEDRO MARIZ’" in the Biomedical Area, Postdoctoral Category.
This moment is not solely about personal achievement; it is a testament to the power of collective effort and collaborative science. I am fortunate to have worked alongside a team of incredibly dedicated researchers and mentors.
