Tendência à gravidade da covid-19 é detectada no sangue, mostra estudo

Uma equipe da Clínica Universitária de Charité, em Berlim, em parceria com o Instituto Francis Crick, de Londres, detectou diferenças no sangue de pacientes com casos leves e graves de covid-19. Esta alteração pode agravar quadros de doenças por patógenos no futuro.

O estudo, publicado na revista especializada Cell Systems contou com a análise de sangue de 31 pacientes nos quais foram verificadas 27 proteínas, que se apresentavam em quantidades diferentes e oscilavam de acordo com a gravidade do contágio.

Estss proteínas foram consideradas marcadores biológicos para que os cientistas pudessem definir se um paciente de covid-19 desenvolveria um quadro mais grave da doença.

“Isso pode potencialmente salvar vida. A pesquisa pode avisar os médicos quais pacientes potencialmente podem desenvolver um quadro mais grave da doença e, assim, considerar as opções de tratamento mais cedo”, explica o diretor do instituto de bioquímica de Charité, Markus Ralser.

Outro ponto é que o uso dessa tecnologia “daria claridade sobre as condições físicas do paciente, independentemente do que ele descreve”, continua.

Em determinadas circunstâncias, o corpo pode não apresentar sintomas físicos do vírus que carrega. Mas a avaliação por estes marcadores biológicos indicaria se o pacientes está contaminado ou não.

Sabendo disso, os pesquisadores, liderados por Markus Ralser, criaram uma forma rápida de medir essas proteínas no sangue. O resultado foi simples: quanto mais grave o caso de covid-19, menos concentração tinham dessas proteínas no sangue.

Dentre as 27 proteínas encontradas como marcadores, algumas ainda não haviam sido relacionadas a uma resposta imunitária ao covid-19.

O próximo passo para a pesquisa é realizar testes em grupos maiores de pacientes, assim como as testagens de pares, procedimentos padrões para criar uma tese científica.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
