Calm in the Time of Coronavirus

Caution and concern rule the day in the time of Coronavirus, as well it should.  But as we work together to prevent the spread of the virus and protect ourselves and our families form infection, there are ways we can both manage our stress and boost our self-care.

“The way I think of it is, if you’re going to be Purell-ing your hands all the time – or as you are washing your hands throughout the day – you can actually practice meditation,” says BHI Medical Director Darshan Mehta, MD.  “Hand washing or use of hand sanitizer is a perfect cue to do a mini relaxation.  While you are moving your hands together, you are counting and breathing deeply, so this gives you both the benefits of fighting off the virus and the internal benefit of knowing that you are taking care of yourself.”

Não usar máscara durante a pandemia é um erro, alertam cientistas chineses

No Ocidente, o uso de máscaras está sendo indicado apenas para pacientes sintomáticos. Mas, como a transmissão pode ser assintomática, a estratégia pode não ser a melhor.

Desde que a pandemia de Covid-19 começou a se espalhar pelo mundo, uma pergunta não para de aparecer: eu devo usar máscaras? Mas a resposta não é tão simples assim. Embora seja uma visão comumente relacionada com pandemias, o uso de máscara não é recomendado pela Organização Mundial de Saúde (OMS), nem pelo Ministério da Saúde do Brasil nem pelo Centro de Controle e Prevenção de Doenças dos Estados Unidos (CDC). Mas especialistas em saúde pública da China discordam.

Em entrevista à revista Science, George Gao, diretor-geral do Centro de Controle e Prevenção de Doenças da China, diz que o maior erro do Ocidente na batalha contra a Covid-19 é não incentivar o uso de máscaras de proteção em massa. O posicionamento é defendido por outros cientistas consultados pela revista, tanto na Ásia como em outros lugares do mundo.

Nerve finding unravels mystery about communication between the gut and brain

Scientists at Flinders University have, for the first time, identified a specific type of sensory nerve ending in the gut and how these may ‘talk’ to the spinal cord, communicating pain or discomfort to the brain.

This discovery is set to inform the development of new medications to treat problems associated with gut-to-brain communication, paving the way for targeted treatments to mitigate related dysfunction.

While our understanding of the gut’s neurosensory abilities has grown rapidly in recent years, two of the great mysteries have been where and how the different types of sensory nerve endings in the gut lie, and how they are activated.

An important step in answering these questions has been made possible through the development of new techniques by Professor Nick Spencer’s Visceral Neurophysiology laboratory at Flinders University in South Australia.

Acetylcholine Supplements: Benefits, Side Effects, and Types

In recent years, nootropics, also called smart drugs, have gained popularity among people looking to improve their mental performance.

Acetylcholine is a neurotransmitter, or brain chemical, that plays a role in many key aspects of brain function, such as memory, thinking, and learning.

While acetylcholine supplements don’t exist, supplements that may indirectly raise acetylcholine levels have become popular among people interested in nootropics as a way to enhance mental performance.

This article explores the benefits and side effects of acetylcholine supplements, and outlines the best types.

Sucrose intake lowers μ-opioid and dopamine D2/3 receptor availability in porcine brain

Average voxel-wise non-displaceable binding potential (BPND) maps superimposed on MRI images in sagittal view. Data are presented for [11C]carfentanil BPND of the 5 minipigs imaged at baseline, after initial exposure to sucrose and after 12 days of sucrose exposure (top row). [11C]carfentanil BPND of all 7 minipigs imaged at baseline and after 12 days of sucrose access are presented in the middle row. [11C]raclopride BPND of all 7 minipigs imaged at baseline and after 12 days of sucrose access are shown in the bottom row. Note that the color scale is exponential to highlight the [11C]raclopride BPND in extrastriatal regions.
