Confocal conics and 4-webs of maximal rank [PDF]

arXiv, 2019
Confocal conics form an orthogonal net. Supplementing this net with one of the following: 1) the net of Cartesian coordinate lines aligned along the principal axes of conics, 2) the net of Apollonian pencils of circles whose foci coincide with the foci of conics, 3) the net of tangents to a conic of the confocal family, we get a planar 4-web.

The Quest for Early Detection of Retinal Disease: 3D CycleGAN-based Translation of Optical Coherence Tomography into Confocal Microscopy [PDF]

Biol. Imaging 4 (2024) e15
Optical coherence tomography (OCT) and confocal microscopy are pivotal in retinal imaging, offering distinct advantages and limitations. In vivo OCT offers rapid, non-invasive imaging but can suffer from clarity issues and motion artifacts, while ex vivo confocal microscopy, providing high-resolution, cellular-detailed color images, is invasive and ...

Peabodies of Constant Width [PDF]

arXiv, 2021
The purpose of this paper is to describe a new $3$-dimensional family of bodies of constant width that we have called peabodies, obtained from the Reuleaux tetrahedron by replacing a small neighborhood of all six edges with sections of an envelope of spheres.

Acacetin reduces endoplasmic reticulum stress through the P‐eNOS/PERK signaling pathway to attenuate MGO‐induced vascular endothelial cell dysfunction

FEBS Open Bio, EarlyView.
We investigated a potential protective effect of acacetin, a naturally occurring flavonoid, against methylglyoxal (MGO)‐induced endothelial dysfunction in human umbilical vein endothelial cells and its mechanism of action. Acacetin can could inhibit MGO‐induced intracellular calcium ion influx, enhance the expression levels of phosphorylated ...

Avances en el estudio fractográfico de fibras cerámicas de circonaerbia mediante microscopía óptica confocal

Boletín de la Sociedad Española de Cerámica y Vidrio, 2005
Laser scanning confocal microscopy (LSCM) is a microscopic technique based on an optical construction which allows the microscope to discard the light coming from unfocused zones of the sample.

Characterisation of the role played by ELMO1, GPR141 and the intergenic polymorphism rs918980 in Fuchs' dystrophy in the Indian population

FEBS Open Bio, EarlyView.
This study reports the upregulation of ELMO1 and GPR141 in human Fuchs' endothelial corneal dystrophy (FECD) corneal endothelium and ultraviolet A‐induced FECD mice model. A genetic association of an intergenic single nucleotide polymorphism rs918980 present between both genes is observed with FECD in the Indian population.

METTL3 knockout accelerates hepatocarcinogenesis via inhibiting endoplasmic reticulum stress response

FEBS Open Bio, EarlyView.
Liver‐specific knockout of N6‐methyladenosine (m6A) methyltransferase METTL3 significantly accelerated hepatic tumor initiation under various oncogenic challenges, contrary to the previously reported oncogenic role of METTL3 in liver cancer cell lines or xenograft models. Mechanistically, METTL3 deficiency reduced m6A deposition on Manf transcripts and
