The DR3 Milky Way Rotation Curve within the Framework of General Relativity Without Dark Matter

open access: yesReports in Advances of Physical Sciences
The GAIA DR3 measurement campaign has produced a MW rotation curve with significantly improved accuracy compared with previous campaigns. In 2023, several authors presented accurate rotation curves calculated from these measurements, within the framework

Defense R&D and information technology in a long-term perspective la rd militaire et les technologies de l'information en longue période [PDF]

open access: yes
Defense R&D is usually considered as an economic burden, implying an eviction effect on civilian R&D and perverting the national systems of innovation. If arms production benefits nowadays from advanced civilian R&D, the flow of technology was not always

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

open access: yesFEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Conclusion

open access: yesReti Medievali Rivista, 2016
This conclusion first points out that the principal merit of the dossier is to make people aware of the diversity of these phenomena, but also of their complexity: what is behind the concept of replication? A place did not need to be ad formam to fulfill

Large scale production of multi-walled carbon nanotubes by fluidized bed catalytic chemical vapor deposition : a parametric study [PDF]

open access: yes, 2007
A parametric study investigating the impact of temperature, run duration, total pressure, and composition of the gaseous phase on the catalytic growth of multi-walled carbon nanotubes (MWNT) has been performed.

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

open access: yesFEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...
