Naukowcy znaleźli sposób, by zwiększyć skuteczność antybiotyków

Ten tekst przeczytasz w 2 min.

W wyniku wieloośrodkowej współpracy badaczy z Monash University w Australii oraz Harvard University w USA odkryto nowy sposób na zwiększenie skuteczności antybiotyków w walce z opornymi drobnoustrojami. Naukowcy dodali do antybiotyku chemoatraktant, związek, który zwiększa liczbę komórek odpornościowych i poprawia ich zdolność do zabijania bakterii.

Ekspertom zależało na tym, by móc zwiększyć siłę antybiotyków bez konieczności zwiększania dawki leku. Według Światowej Organizacji Zdrowia oporność drobnoustrojów na antybiotyki ewoluuje i jest jednym z największych globalnych zagrożeń zdrowia publicznego.

Antybiotyk z zawartością chemoatraktantu wykazał dwukrotnie lepsze efekty leczenia infekcji

Podczas infekcji bakteryjnej organizm, by zwalczyć drobnoustroje wykorzystuje cząsteczki zwane chemoatraktantami, które angażują neutrofile do miejsca infekcji. Neutrofile są komórkami odpornościowymi, które mają zdolność zabijania drobnoustrojów i pełnią kluczową rolę w odpowiedzi immunologicznej organizmu. Naukowcy postanowili wykorzystać siłę chemoatraktantów i zastosować ją w walce z opornymi drobnoustrojami.

Naukowcy podczas badań wprowadzili chemoatraktanty do wankomycyny, antybiotyku przeznaczonego do zwalczania bakterii Gram-dodatnich, w tym gronkowca złocistego (MRSA). Przetestowali rozwiązanie na modelach mysich zainfekowanych gronkowcem złocistym. Prof. Max Cryle, z Monash Biomedicine Discovery Institute, zaznaczył, że poprzez taką stymulację układu odpornościowego leczenie infekcji okazało się dwukrotnie skuteczniejsze niż stosowanie samego antybiotyku.

Ta bardzo obiecująca nowa ścieżka badań przynosi wiele potencjalnych korzyści w obliczu stale rosnącego zagrożenia superbakteriami lekoopornymi – dodał ekspert.

MRSA rozwija oporność na wiele antybiotyków i potrafi uniknąć układ odpornościowy

Gronkowiec złocisty to powszechnie występująca bakteria, której nosicielstwo może być bezobjawowe i nieszkodliwe. W przypadku uszkodzeń skóry, urazu, zabiegu chirurgicznego lub osłabienia odporności nosiciela, gronkowiec może powodować zakażenie. Gronkowiec złocisty powoduje zapalenie mieszków włosowych, czyraki i liszajec. Zakażenie tym drobnoustrojem może również prowadzić do powstania ropni w skórze i wewnątrz ciała, a także szerzyć się do kości, płuc, krwi, serca i innych narządów.

Zakażenie MRSA rozwija się często u pacjentów po zabiegach chirurgicznych, zwłaszcza u tych, którzy byli wcześniej leczeni antybiotykami i są narażeni na kontakt z nosicielami MRSA. Gronkowiec złocisty potrafi rozwinąć oporność na wiele antybiotyków, a także uniknąć układ odpornościowy gospodarza. Objawy zakażenia chirurgicznego rany obejmują jej zaczerwienienie, obrzęk i ból.

TSN’s Bob Weeks argues the LPGA star deserves the nod after a great season that saw her become the first Canadian to have multiple major titles. Henderson of Smiths Falls, Ont., won the 11th and 12th tournaments of her career, adding to her all-time Canadian record.

    Global sports media business LiveScore has named Juventus star Cristiano Ronaldo as the firm’s official global brand ambassador. Ronaldo’s goal ruled offside! Not his night. He picks the ball from the net and smashes into the stands in frustration. A long ball is played into the Sheriff penalty area and Bruno squares it to Ronaldo in front of goal. Ronaldo is able to finish this time, only to turn back and look at the assistant raise his flag. As LiveScore continues its rapid evolution as a major global sports media force, the world’s most famous footballer and five-time Ballon d’Or winner Ronaldo will team up with the brand. Sports media company LiveScore has announced Portugal and Real Madrid striker Cristiano Ronaldo as its global brand ambassador.

  5. Она делает все: и объем придает, и удлинение, и цвет у нее черный-причерный. Ресницы получаются реально чумовые. Держится — отлично, смывается теплой водой — легко. (Вообще любая термотушь должна так смываться теплой водой, но некоторые экземпляры приходится долго размачивать в пальцах, не здорово.) Вид средства – Тушь Судя по всему, тушь хорошая. «Сольные партии» удаются фиолетовой туши лучше всего, просто подкрути ресницы с помощью щипцов и нанеси тушь в 2-3 слоя. Другой вариант – скорее вечерний – сочетать сиреневую тушь с тонкой темно-зеленой подводкой. Ее 306 щетинок гарантируют ровное и интенсивное нанесение, без комочков или избытка туши. Невероятно мягкая щеточка расчесывает ресницы. Ее более короткие щетинки наносят тушь на ресницы по всей длине, начиная с корней, в то время как более длинные щетинки обеспечивают окрашивание ресниц до самых кончиков.

  15. I sure do! As mentioned before, real time games are hit or miss for some people. This one’s light enough, and fast enough, that even people who don’t like stress will enjoy themselves. Knock a game out in 15 minutes or so, and play again, or not. a good game for childrem … simple but good graphics Also available on: Amiga – Amstrad CPC – Atari ST – Commodore 64 – ZX Spectrum There are certainly some downsides to this game. If you’re averse to games with a high degree of luck, then you might not enjoy Fast Food Fear. Because it’s a pure card game, you could go several turns without getting a card that you need. Also, if you don’t enjoy cooperating with other people…well then this one is definitely not for you. Might I suggest a good game of Solitaire? We only played one of the first levels in the game, but it was still rather hectic. Customers not only want you to greet them in a polite fashion, but they want you to say good-bye as well. An icon will pop up prompting you to shake your nunchuk to say good-bye, but it’s easy to miss when you’re knee deep in ketchup and onions. When the customer is done eating, you have to take their hard-earned cash, and this brings up a calculator where you tally how much their food cost. If you take too long to perform any of these tasks, or if you forget to say good-bye, the customer will leave grumpy, which is as bad for business as a hair in a chocolate milk shake.

    The new Game & Watch takes the shape of the original with its red and gold design, but charges by USB-C and comes in color. It plays three games: „Super Mario Bros.,” „Super Mario Bros.: The Lost Levels” and „Ball (the Mario version).” Only „Ball,” a juggling game, stays in black and white. The Game & Watch series proved to be Nintendo’s first major video game hit, and its popularity steered the company in an entirely new direction from that point on. After successfully launching its own home console with the Famicom in 1983 (released a couple of years laters as the NES outside of Japan), Nintendo and Game & Watch creator Gunpei Yokoi began working on a new product that would combine the portability of the original handheld concept with the swappable cartridges of more traditional video game consoles: the Game Boy.
