🔬 Científicos de la Facultad de Ciencias, UNAM y la Universidad de Arabia Saudita descubrieron el nucléolo en células procariontes (Arqueas), un hallazgo que cambia el paradigma de la biología celular.

#LaBioZona te desglosa este importante notición, que lo cambia TODO 👇👇👇 El nucléolo de la arquea Sa...
Para entender este hallazgo necesitamos entender dos cosas: a) qué es un nucléolo y b) qué carambas es una arquea.
a) El #núcleo celular (en donde está casi todo el genoma) es una estructura tradicionalmente descrita solo en #eucariontes (como tú, yo, tu gato, Paramecium, tardígrados, los champiñones y el árbol del parque).

The Correct answer is (C)
(1/5)Recombinant vector vaccines are made through genetic engineering. The gene that creates the protein for a bacteria or virus is isolated and placed inside another cell’s genes.
(2/5)When that cell reproduces, it produces vaccine proteins that mean the immune system will recognize the protein and protect the body against it. Hence, statement 1 is correct.

💥UPDATE NOV 21, 2022

How to document your purchases-

1) If you ordered online from you need to include the email address (s) you used

2) A receipt for the impacted product from Jan 1, 2020-November 2020.

2/ Many bought their products via 3rd parties. Initially I bought mine through Amazon, the directly via The Laundress, so I have receipts.

However, if you don’t have the above, you need to include a photo of the product w/the Lot # and your initials + the date. See notice MORE
3/I personally recommend wearing a well-fitted N95 or better (use surgical tape or silicone tape for seal, double glove, sealed goggles-or tape around your glasses as Pseudomonas is spread by inhalation, eyes, wounds & micro tears.

One issue is that the company says MORE

El 60-80% de las #amigdalitis/faringoamigdalitis/faringitis son causadas por #virus. Es menos frecuente que sea causado por bacterias, por lo tanto, si usted se toma un #antibiótico cada ves que le duele la garganta, está cometiendo un grave #error.

Le explico la diferencia


Son las más frecuentes, los síntomas suelen ser más #leves. Es habitual encontrar una garganta muy enrojecida, a veces con vesículas; tendrán también moco, en ocasiones estornudos, fiebre y tos. La evolución es benigna, se curan en pocos días y no tienen complicaciones. ImageImageImage

La #bacteria más frecuente es Streptococcus pyogenes (estreptococo del grupo A), pero otras bacterias también pueden causar amigdalitis. Suelen presentar fiebre elevada, dolor intenso de garganta, mal aliento y de forma muy habitual “placas de pus” sobre las amígdalas ImageImageImageImage

"Active matter *employs* control, either internally [e.g., embryogenesis] or externally [e.g., with sheepdogs]."

Le infezioni batteriche resistenti agli antibiotici

Ma si possono trattare con un virus.

A thread

#antibioticresistance #antibiotics #bacteria #infectiousdiseases

Ogni anno in Italia muoiono più di 11'000 persone per infezioni resistenti agli antibiotici. E il problema non riguarda soltanto soggetti anziani, debilitati o ospedalizzati.

Se il fenomeno dell'antibiotico resistenza non viene arginato ci ritroveremo con moltissimi batteri letali.

Gli antibiotici che fino ad oggi ci hanno aiutato a gestire questa battaglia sono definiti la più grande scoperta della medicina moderna.

Lo que usted debe saber sobre la #tuberculosis (TB).

La TB es una enfermedad infecciosa causada fundamentalmente por la bacteria #Mycobacterium tuberculosis.

La enfermedad suele afectar principalmente a los #pulmones 🫁 pero puede comprometer cualquier órgano del cuerpo.

🧵 Image
¿Como se transmite?

De persona a persona por vía aérea.

"Cuando una persona con #tuberculosis expulsa la #bacteria al #toser, estornudar, hablar, entonces los que se encuentren cerca pueden inhalarla e infectarse"

Generalmente ocurre en contactos cercanos y prolongados. Image
¿Quiénes tienen más riesgos?

❗️Las personas que viven con #VIH (sin TARV) tienen 18 veces más probabilidades de desarrollar TB activa.
❗️La personas desnutridas.
❗️El trastorno por consumo de alcohol y el tabaquismo.
❗️Otros estados de inmunosupresión.…

This is the most straightforward explanation for chronic symptoms in at least a subset of #LongCovid patients. Partly b/c if the #virus is still present its activity can directly contribute to other phenomena also being documented in LongCovid
2/ Persistence of #SARS-CoV-2 in tissue could lead to shedding of spike protein into blood, which can catalyze the ongoing formation of microclots and hyperactivated platelets
3/ Persistence of SARS-CoV-2 can lead to ongoing downregulation of interferon and/or T cell signaling by the virus, creating an optimal atmosphere for activation of EBV or other #pathogens normally controlled by such immunity

⭐️ It is with immense pleasure that we share with you the published #Sitophilus oryzae #genome paper in @BMCBiology… 1/n
S. oryzae is a #coleopteran capable of destroying entire cereal crops posing a significant threat to the food security of many developing countries. The female #weevil lays ~300 eggs during its lifetime. They develop within the cereal grain until a ~3 day old adult emerges 2/n Image
Cereal grains are nutritionally poor, and S. oryzae partnered with a gram- bacterium that complements its diet. The bacteria are present within specialized insect cells, called #bacteriocytes. Check here for our latest research on this #symbiosis…. 3/n

In our recent review on #LongCovid/PASC we bring up the possibility that dysbiosis or imbalance of host #microbiome communities (in ecosytems such as the gut, lungs, or oral cavity) might contribute to at least some LongCovid symptoms:…
2/ More specifically immune dysregulation driven by #SARS-CoV-2 might allow pathobionts (bacteria capable of both commensal + virulent acitivty) in the gut, mouth, or other body sites to collectively shift towards a state of imbalance + pro-inflammatory gene/metabolite expression
3/ Conversely, b/c composition + activity of the microbiome can influence host susceptibility and ongoing control of #viral pathogens, exisiting microbiome dysbiosis in a range of body sites may serve as a form of predisposition to LongCovid

If you’re considering studying blockage of GPCRs in #LongCovid or related conditions, please start w/ the understanding that humans are not sterile...and that common human organisms/pathogens express proteins/metabolites that block/dysregulate GPCR signaling
2/ Herpesvirus re-activation is common in #COVID-19, and may impact some LongCovid cases. The herpesviruses alone (EBV, CMV etc) create a wide range of proteins that block GPCR signaling:… Indeed, viral hijacking of GPCRs is a big topic in cancer research
3/ Beyond that, many commensal #bacteria derived from the human #microbiome appear capable of expressing metabolites that are GPCR mimics, that directly impact GPCR signaling. That means even changing microbiome dynamics could impact GPCR-related issues:…

And so Day 3 of my story of God at work in my life as part of #OfGodAndMe #ThisNunsStory series. Yesterday mention of the book, The Silver Sword seems to have struck a chord with many so perhaps its not out of place to mention that today 7th April is #Worldhealthday 1/20
Ian Serraillier ended his talks by showing this photo with the words, ‘No child should ever again have that expression on his face’. My hope this the UK as host of the upcoming #G7 summit will prioritise Universal health care for all. #UCH 2/20
