CitarTesla TSLA saw its target price upped to $810 from $540 by Morgan Stanley, which reiterated an overweight call on the electric-vehicle maker. Barclays, by contrast, reiterated its $230 price target.
A MS dá um target de 810$ e o Barclays de 230$?
Percebe-se bem quem está enfiado nisto até ao tutano!
a médica explicou que a vacina ativa o sistema imunitário, exatamente o contrário do desejado (reduzir o sistema imunitário).
Que para ser administrada, teria que existir uma declaração do oncologista a atestar essa necessidade.
As bolsas batem recordes, as casas batem recordes a economia mundial e portuguesa bate recorde... o pib não para de subir principalmente este ano.
The Science Behind How the Coronavirus Affects the Brain
The Mysterious Link Between COVID-19 and Sleep
Her colleague Arun Venkatesan has been trying to get to the bottom of how a virus could cause insomnia. He focuses specifically on autoimmune and inflammatory diseases that affect the nervous system. Initially, Venkatesan says, the common assumption among doctors was that many post-COVID-19 symptoms were due to an autoimmune reaction—a misguided, targeted attack on cells of one’s own body. This can happen in the nervous system after infections by various viruses, in predictable patterns, such as that of Guillain-Barré syndrome. In the days after an infection, as new antibodies mistakenly attack nerves, weakness and numbness spread from the tips of the extremities inward. Disconcerting as it can be, this type of pattern is at least identifiable and predictable; doctors can tell patients what they’re dealing with and what to expect.
By contrast, the post-COVID-19 patterns are sporadic, not clearly autoimmune in nature, says Venkatesan. The symptoms can appear even after a mild case of COVID-19, and timescales vary. “We’ve seen a number of patients who were not even hospitalized, and felt much better for weeks, before worsening,” Venkatesan says. And the findings aren’t limited to the brain. At Northwestern University, the radiologist Swati Deshmukh has been fielding a steady stream of cases in which people experience nerve damage throughout the body. She has been looking for evidence that the virus itself might be killing nerve cells. Hepatitis C and herpes viruses are known to do so, and autopsies have found SARS-CoV-2 inside nerves in the brain.
Still, she believes, symptoms are most likely due to inflammation. Indeed, the leading theory to explain how a virus can cause such a wide variety of neurologic symptoms over a variety of timescales comes down to haphazard inflammation—less a targeted attack than an indiscriminate brawl. This effect is seen in a condition known as myalgic encephalomyelitis, sometimes called chronic fatigue syndrome. The diagnosis encompasses myriad potential symptoms, and likely involves multiple types of cellular injury or miscommunication. In some cases, damage comes from prolonged, low-level oxygen deprivation (as after severe pneumonia). In others, the damage to nerve-cell communication could come by way of inflammatory processes that directly tweak the functioning of our neural grids.
Se a vacina vai estimular o sistema imunitario, nao podera ser mau a quem ja o tem normalmente?
Teria ideia que ao ter o sistema imunitario de forma a que "ataque" o corpo (muito estimulado) ja por si , por doença auto imune , a vacina nao vai piorar ainda mais? ou podera?
pura ignorancia minha
Portanto, daqui a 1 ano, toda a população ativa, aquela que se movimenta diariamente, aquela que trabalha junto de colegas, aquela que propaga o virús, ainda não estará vacinada.bom, mas daqui a menos de um ano e ainda antes dessa população activa ser vacinada, já os que a levaram têm de levar mais outra dose
Isto vai correr bem daqui a 1 ano..
li ontem qualquer coisa que dizia que a vacina que "dura" mais, daquelas aprovadas, é a que dura 116 dias onde o "paciente" está imune.
tá bonito, tá.
Vacina da Moderna com 94,5% eficácia… Segundo várias fontes.
https://investors.modernatx.com/news-releases/news-release-details/modernas-covid-19-vaccine-candidate-meets-its-primary-efficacy
Com 2% dos vacinados com efeitos secundários graves (severe) de classe 3...pois é.
quais são os efeitos?
Grade 3 (severe) events greater than or equal to 2% in frequency after the first dose included injection site pain (2.7%), and after the second dose included fatigue (9.7%), myalgia (8.9%), arthralgia (5.2%), headache (4.5%), pain (4.1%) and erythema/redness at the injection site (2.0%). These solicited adverse events were generally short-lived. These data are subject to change based on ongoing analysis of further Phase 3 COVE study data and final analysis.
