Unveiling the Functional Role of KIF21B in Microglia Inflammatory Response
Glia, Volume 74, Issue 9, September 2026.Microglia express KIF21B in both sexes. KIF21B binds to microglia cytoskeleton; inflammation alters such interaction promoting a phagocytic state in females. In male microglia KIF21B modulates migration. ABSTRACT Microglia are brain immune cells that maintain homeostasis and respond to injury, changing cell morphology to drive inflammation, migration ...

Journal of Biomedical Materials Research Part A, Volume 114, Issue 9, September 2026.ABSTRACT Critical bone defects present significant clinical challenges due to their debilitating nature and associated costs. Tissue engineering offers a promising solution, employing biomaterials like porous chitosan (CH) and xanthan gum (XG) membranes as scaffolds for tissue regeneration.

Measurement of Ultra-High Energy Cosmic Rays with CHICOS [PDF]
, 2009 The California HIgh school Cosmic ray ObServatory (CHICOS) is a ground-based scintillator array designed to measure the extended air showers of ultra-high energy cosmic rays. The goal of the project is to gain insight into the origin of ultra-high energy

, 2013 This final chapter introduces a classical example of sources emitting high energy radiation. A strong effort has been made to introduce these sources at a basic level: no pre-knowledge is required. They are one of the best fields of research where we can use what studied in all the previous chapters: we will apply the just learnt theory to the most ...

The Realm of the First Quasars in the Universe: the X-ray View
, 2007 We review the X-ray studies of the highest redshift quasars, focusing on the results obtained with Chandra and XMM-Newton. Overall, the X-ray and broad-band properties of z>4 quasars and local quasars are similar, suggesting that the small-scale X ...

ChemSystemsChem, Volume 8, Issue 5, September 2026.Investigation of the photoswitching kinetics of a spiropyran–merocyanine (SP–MC) derivative in different solvents reveals that decreasing solvent polarity limits MC formation through aggregation, disfavoring nonpolar environments. In contrast, SP formation remains largely insensitive to solvent polarity, reflecting the greater thermodynamic stability ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

An accretion disc-corona model for X-ray spectra of active galactic nuclei
, 2009 The hard X-ray emission of active galactic nuclei (AGN) is believed to originate from the hot coronae above the cold accretion discs. The hard X-ray spectral index is found to be correlated with the Eddington ratio L(bol)/L(Edd), and the hard X-ray ...
