    I was only saying to someone yesterday that at one point very early on, the world had the chance to eliminate #SarsCOV2

    We had an unprecedented global connection and we blew it.

    Yes, you're so right, they just aren't quite the same and it's awful to see.

  2. UNAM, IPN e IMSS desarrollan prueba rápida e innovadora para detectar SARS-CoV-2

    Podría identificar, en una sola prueba, COVID, influenza y virus sincicial respiratorio; incluso dengue, chikungunya y Zika


    Por Martín García | Reportero                                      

    De manera más rápida y precisa será posible detectar y cuantificar el virus del SARS-CoV-2, causante de la pandemia de la COVID-19, con una metodología desarrollada por un grupo interdisciplinario de investigación de la UNAM, del Instituto Politécnico Nacional (IPN) y del Instituto Mexicano del Seguro Social (IMSS).

    Primero en muestras de estándares sintéticos y después en muestras de pacientes, mediante un dispositivo microfluídico que en un futuro facilitará realizar pruebas fuera de los laboratorios, es decir, en clínicas y centros de salud con atención médica básica.

    La metodología fue publicada en un artículo científico de la revista Microsystems & Nanoengineering, perteneciente al grupo editorial Nature.

    El proyecto -donde se conjuntan las capacidades de infraestructura de cada institución para abordar diversos aspectos- lo integraron: 

    Luis Fernando Olguín Contreras, académico de la Facultad de Química (FQ); Laura Oropeza Ramos, docente de la Facultad de Ingeniería (FI); Luis Álvarez Icaza y Óscar Pilloni Choreño, investigadores del Instituto de Ingeniería (IIngen); Kenia Chávez Ramos, Frida Trejo y Prisciluis Caheri Salas Navarrete, posdoctorantes en la Universidad Nacional. Asimismo, Eva Ramón Gallegos, del IPN; y José Esteban Muñoz Medina, del IMSS.

    Más aplicaciones

    La microtecnología propuesta permite dividir una muestra del paciente en miles de microgotas utilizando un dispositivo microfluídico. En cada una se realiza una reacción bioquímica y después se analiza el porcentaje de las positivas para determinar de forma absoluta el número de partículas virales, explicó Kenia Chavez.

    Además, la reacción bioquímica utilizada en la detección se produce a una temperatura constante. En cambio, la PCR, que es el patrón de referencia, requiere cambios de temperatura drásticos. Con ello podemos llevar a cabo la detección del SARS-CoV-2 en un ensayo con una duración de 30 minutos, en vez de las dos horas empleadas en la PCR, acotó Luis Olguín.

    Es el primer paso que se ve plasmado en una publicación importante a nivel internacional, indicaron Laura Oropeza y Luis Álvarez Icaza.

    En México, destacaron Caheri Salas y Esteban Muñoz, “circulan tres virus respiratorios de importancia: COVID, influenza y virus sincicial respiratorio; entonces, este trabajo podría ser modificado para detectarlos en una sola prueba, lo cual representaría un ahorro económico relevante. Otras enfermedades que sería capaz de localizar son el dengue, chikungunya y Zika.

    Oscar Pilloni resaltó que una de las aplicaciones será contar con un equipo portátil, “factible de llevar a lugares en donde no se cuenten con laboratorios de biología molecular para diagnóstico, así como realizar pruebas para mayor cantidad de enfermedades y, en un solo ensayo, tener el diagnóstico para varios padecimientos”.

    A decir de Laura Oropeza, subraya la importancia de la interdisciplina donde todas las áreas son fundamentales, en este caso se laboró a partir de la ingeniería, microfluídica, microfabricación, bioquímica, biotecnología y la medicina, entre otras. Además, la publicación es fundamental porque amplía la posibilidad de llevarlo a un proceso tecnológico.

    En el artículo titulado Critical aspects of droplet digital reverse transcription loop-mediated isothermal amplification (ddRT-LAMP) for viral pathogens detection (Aspectos críticos para la detección de patógenos virales utilizando la transcripción reversa y la amplificación isotérmica por bucle digital en microgotas [Chavez et al Microsyst Nanoeng 11, 137, 2025]) participaron, por parte de la Universidad Nacional las investigadoras e investigadores de la FQ y de FI, así como del IIngen. –sn–

  4. ⚠️ This implies that in survivors of mild COVID-19, which is most people, over 1 in 3 cases of new-onset dementia is due to COVID-19 ⚠️

    adults aged 50 years and older from the UK Biobank over a median observational period exceeding two years following COVID-19 infection

    compared with those in propensity-score-matched controls without COVID-19 and in individuals with non-COVID respiratory illnesses

    COVID-19 survivors had a higher likelihood of developing new-onset dementia compared to uninfected controls

    association between COVID-19 and all-cause dementia (adjusted Hazard Ratio: 1.58)

    The underlying pathophysiology likely involves prothrombotic, inflammatory, and microvascular dysfunction mechanisms, contributing to cerebral small vessel disease, blood-brain barrier disruption, and chronic cerebral hypoperfusion, ultimately leading to cognitive impairments and dementia

    Abstract
    Middle East respiratory syndrome coronavirus (MERS-CoV) circulates in dromedary camels in the Arabian Peninsula and occasionally causes spillover infections in humans. MERS-CoV diversity is poorly understood because of the lack of sampling during the COVID-19 pandemic. We collected 558 swab samples from dromedary camels in Saudi Arabia during November 2023–January 2024. We found 39% were positive for MERS-CoV RNA by reverse transcription PCR. We sequenced 42 MERS-CoVs and 7 human 229E-related coronaviruses from camel swab samples by using high-throughput sequencing. Sequences from both viruses formed monophyletic clades apical to recently available genomes. MERS-CoV sequences were most similar to B5 lineage sequences and harbored unique genetic features, including novel amino acid polymorphisms in the spike protein. Further characterization will be required to understand their effects. MERS-CoV spillover into humans poses considerable public health concerns. Our findings indicate surveillance and phenotypic studies are needed to identify and monitor MERS-CoV pandemic potential.

    Yes yes yes omggg

    Can you (theoretically) 3D design / print an off-brand filter case for See Us 95?
    Theirs are so dainty they break mid-use, leaving you with one side flopping off while walking about.

    Or even just an ergonomic ring shape with smooth hook nubs at the edge for straps to tie or loop onto.

    That way, you use any surgical or actual KN99 or FFP3 respirator as the filter.
    Then you fit this plastic edge press over it, pressing the (new) seal firmly against your skin.

    Tada! Your fit test is now actually likely to pass!

    ABSTRACT
    Human-to-human transmission of the highly pathogenic Middle East respiratory syndrome coronavirus (MERS-CoV) is currently inefficient. However, there is concern that the virus might mutate and thereby increase its transmissibility and thus pandemic potential. The pandemic SARS-CoV-2 depends on a highly cleavable furin motif at the S1/S2 site of the viral spike (S) protein for efficient lung cell entry, transmission, and pathogenicity. Here, by employing pseudotyped particles, we investigated whether augmented cleavage at the S1/S2 site also increases MERS-CoV entry into Calu-3 human lung cells. We report that polymorphism T746K at the S1/S2 cleavage site or optimization of the furin motif increases S protein cleavage but not lung cell entry. These findings suggest that, unlike what has been reported for SARS-CoV-2, a highly cleavable S1/S2 site might not augment MERS-CoV infectivity for human lung cells.

  13. "It is important to note that no government has said COVID-19 has gone away and that we can resume unmitigated social interactions facing the same risks we did in 2019. Instead, official messaging has centered around the idea of individual responsibility, that we should each engage in our own assessment of the risks of SARS-CoV-2 infection. This feels a little like government smoking policy in the 1950s;"
