Apoptosis

Here’s how fast cell death can strike

Scientists have clocked the speed of a form of cellular suicide called apoptosis

prostate tumor cells going through apoptosis
DYING BY THE NUMBERS  In this electron micrograph, prostate tumor cells dying from a type of programmed cell death called apoptosis are shown (purple) alongside healthy cancer cells (yellow). Scientists are learning more about how apoptosis spreads through cells.

Scientists now know how long it takes for a cell to tell itself it’s time to die.
Signals triggering a type of cell suicide called apoptosis move through a cell like a wave, traveling at a rate of 30 micrometers per minute, Stanford University systems biologists Xianrui Cheng and James Ferrell Jr. report in the Aug. 10 Science.
These findings resolve a debate over whether these death signals spread by diffusion, with signaling molecules working their own way across a cell, or as self-regenerating trigger waves, like toppling dominoes. The apoptosis process starts with damage that causes the release of death signal chemicals. One example is cytochrome c leaking from damaged mitochondria, the cell’s power plant. Once cytochrome c concentrations get high enough, the chemicals signal proteins called caspases to go to work. Caspases trigger other proteins to poke holes in neighboring mitochondria, releasing more cytochrome c and moving the death wave across the cell. That chain reaction happens more quickly than diffusion can, Ferrell says. In an African clawed frog egg, a trigger wave takes about a half-hour to spread across the 1.2 millimeter cell, whereas diffusion would take five hours, he says.
Like forest fires, trigger waves will keep going as long as there is fuel to feed them — in this case, the death signal chemicals and proteins, Ferrell says. He predicts that many other biological signals may move as trigger waves.
“We biologists are just waking to this idea that trigger waves are a recurring theme in biological communication,” Ferrell says.
Discovering that apoptosis travels as trigger waves in cells may give scientists clues about how to persuade cancer cells to kill themselves (SN: 1/21/17, p. 10). Or researchers may learn how to prevent cells from dying in conditions such as Alzheimer’s disease or muscular dystrophy.

Monitoring equity in universal health coverage with essential services for neglected tropical diseases: an analysis of data reported for five diseases in 123 countries over 9 years

Summary


Background

A service coverage index has recently been proposed to monitor progress towards universal health coverage (UHC), and baseline results for 2015 are available. However, evidence on equity in that progress is scarce. The service coverage index did not consider services for neglected tropical diseases (NTDs), a group of preventable diseases defined by WHO member states on the basis of the disproportionate burden they place on their poorest, remotest, and otherwise most marginalised communities. Because of the much-needed equity lens that it could provide, NTD service coverage should not be neglected in efforts to monitor UHC progress.

Som: antigravidade

Som é um tipo de antigravidade, pois tem massa negativa: estudo

Por , em 13.08.2018

De acordo com um novo estudo da Universidade de Columbia (EUA), o som tem massa negativa, o que significa que sobe muito lentamente para longe, como uma estranha fonte de “antigravidade”.
A descoberta quebra o nosso entendimento convencional sobre as ondas sonoras como ondulações sem massa que atravessam a matéria, dando às moléculas um empurrão, mas balanceando qualquer movimento ascendente com um movimento descendente igual e oposto.
Os cientistas afirmam que esse é um modelo simples que explica o comportamento do som na maioria das circunstâncias, mas não é verdade para todos os casos.

Antigravidade

Quando o som se move através do ar, vibra as moléculas ao seu redor, mas essa vibração não pode ser facilmente descrita pelo movimento das próprias moléculas.
Em vez disso, assim como as ondas de luz podem ser descritas como fótons, os fônons são as unidades de vibração usadas para descrever as ondas sonoras que emergem das complicadas interações das moléculas. Nenhuma partícula física surge, mas os pesquisadores podem usar a matemática das partículas para descrevê-lo.

Ignaz Semmelweis (1818 - 08/13/1865)

Ignaz Philipp Semmelweis

GERMAN-HUNGARIAN PHYSICIAN
Alternative Titles: Ignác Fülöp Semmelweis, Ignaz Philipp Semmelweis

Ignaz Semmelweis, in full Ignaz Philipp Semmelweis or Hungarian Ignác Fülöp Semmelweis, (born July 1, 1818, Buda, Hungary, Austrian Empire [now Budapest, Hungary]—died August 13, 1865, Vienna, Austria), German Hungarian physician who discovered the cause of puerperal (childbed) fever and introduced antisepsis into medical practice.
Educated at the universities of Pest and Vienna, Semmelweis received his doctor’s degree from Vienna in 1844 and was appointed assistant at the obstetric clinic in Vienna. He soon became involved in the problem of puerperal infection, the scourge of maternity hospitals throughout Europe. Although most women delivered at home, those who had to seek hospitalization because of poverty, illegitimacy, or obstetrical complications faced mortality rates ranging as high as 25–30 percent. Some thought that the infection was induced by overcrowding, poor ventilation, the onset of lactation, or miasma. Semmelweis proceeded to investigate its cause over the strong objections of his chief, who, like other continental physicians, had reconciled himself to the idea that the disease was unpreventable.
