'Derrotado frente a su hijo, el coronel Márquez volvió a la vida civil y vivió más de tres décadas como veterano de guerra, hasta que murió en 1937. García Márquez vivió con él, sus padres lo dejaron a su cuidado desde que era un bebé, y siempre contaba que uno de sus primeros recuerdos de infancia era dormir en un colchón junto a la cama del coronel.'

Regulatory CARTs #preprint

"The InsB-g7 CAR re-directed NOD Treg specificity such that insulin B 10-23-peptide stimulation enhanced suppressive function, measured via reduction of proliferation and IL-2 production by BDC2.5 T cells and CD80 and CD86 expression on dendritic cells. Co-transfer of InsB-g7 CAR Tregs prevented adoptive transfer diabetes by BDC2.5 T cells in immunodeficient NOD mice"

A reasonable proposition:

"Given the growth of withdrawals due to negative confirmatory trials and emerging evidence on the high spending associated with AA drugs, it is critical to balance early access against population-level exposure to cancer therapies with no benefit over standard of care."

In Aicardi-Goutières syndrome patient samples

"Using machine-learning approaches and differential gene expression we identified a drastic loss of transcription factor hypoxia induced factor 1 alpha (HIF-1a) expression and activity associated with features of a metabolic switch and mitochondrial stress in monocytes/dendritic cells."

Fits well with earlier work from Jocelyne's lab:

"Type I IFN sets the stringency of B cell repertoire selection in the bone marrow" (1999)

and

"Type I Interferon controls the onset and severity of autoimmune manifestations in lpr mice" (2003)

'The results provide evidence that elevated IFNα levels act directly on B cells to facilitate autoantibody production and further highlight the importance of IFN signaling as a potential therapeutic target in SLE.'

"Here, we show that p53, one of the most commonly inactivated tumor suppressors in glioma, is a gatekeeper of astrocyte fate. In the context of stab-wound injury, p53 loss destabilized the identity of astrocytes, priming them to dedifferentiate in later life."

'Diverse animals such as corals, polychaete worms, and certain fishes are thought to synchronize their reproductive behavior by the moon. Such animals—including more than 100 coral species at the Great Barrier Reef—release their eggs before fertilization takes place, and synchronization maximizes the probability of an encounter between eggs and sperm.'

@sentient_water The previous vice chancellor, Louise Richardson, actively defended the policy:

"She has warned against the “cancellation” of benefactors, whether the colonialist Cecil Rhodes or the opioid-seller Mortimer Sackler. "

"The US price of Humira, which AbbVie has increased more than 20 times to exploit its monopoly there, is finally under pressure. Having been legally shielded until now, the drug this year faces competition from nine “biosimilars” such as Amgen’s Amjevita. This may bring relief to patients who have faced bills of thousands of dollars, despite being insured."

"When I was a young person, libraries were where I went to find stories that made me feel I could fit in, not only in North Dakota, but in the wider world. But two pieces of legislation that may soon be signed into law in North Dakota would make it possible to restrict libraries and, in some cases, to imprison librarians."

A step back for antivirals: the EMA gives molnupiravir thumbs down, based on the lack of strong evidence for efficacy.

'La Agencia Europea del Medicamento (EMA) considera que la falta de eficacia del molnupiravir, comercializado como Lagevrio y que fue el primer tratamiento oral contra la covid utilizado de forma experimental durante la pandemia, hace que su comercialización y uso en los sistemas sanitarios no sea recomendable.'

'Toda una generación de niños de Caldes D‘Estrac, a 40 kilómetros de Barcelona, quedó marcada entre 1970 y 1975 por los abusos del sacerdote Josep Vendrell Cortasa, según denuncian al menos seis antiguos alumnos suyos en el colegio e internado del pueblo, donde era director, además de párroco de la iglesia de Santa María y responsable del grupo scout.'
