Inhibition of cAMP/PKA Pathway Protects Optic Nerve Head Astrocytes against Oxidative Stress by Akt/Bax Phosphorylation-Mediated Mfn1/2 Oligomerization. [PDF]

open access: yes, 2019
Glaucoma is characterized by a progressive optic nerve degeneration and retinal ganglion cell loss, but the underlying biological basis for the accompanying neurodegeneration is not known.

Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling

open access: yesAdvanced Materials, EarlyView.
3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

The branching nerve of HDA and the Kan condition [PDF]

open access: yesTheory and Applications of Categories, Vol. 11, 2003, No. 3, pp 75-106, 2001
One can associate to any strict globular $\omega$-category three augmented simplicial nerves called the globular nerve, the branching and the merging semi-cubical nerves. If this strict globular $\omega$-category is freely generated by a precubical set, then the corresponding homology theories contain different informations about the geometry of the ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Theory of Bowstring Disease: Diagnosis and Treatment Bowstring Disease

open access: yesOrthopaedic Surgery, 2019
Bowstring disease (BSD) is a new classification of spine disease caused by axial stretched lesion on nerve roots and the spinal cord, which is differentiated from disc herniation and canal stenosis in that it is caused by nerve compression lesions.

Rescuing axons from degeneration does not affect retinal ganglion cell death

open access: yesBrazilian Journal of Medical and Biological Research, 2016
After a traumatic injury to the central nervous system, the distal stumps of axons undergo Wallerian degeneration (WD), an event that comprises cytoskeleton and myelin breakdown, astrocytic gliosis, and overexpression of proteins that inhibit axonal ...
