Optimization of the Antenna Array with Cosequences Pattern

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2016
The method of partial directional diagrams (PDD) synthesized vertical omnidirectional in azimuth plane antenna arrays (AR) with cosequences PDD form in the vertical plane. The AR optimum height on the criterion of maximum gain is determinated.

A Novel HDL-Mimetic Peptide HM-10/10 Protects RPE and Photoreceptors in Murine Models of Retinal Degeneration. [PDF]

open access: yes, 2019
Age-related macular degeneration (AMD) is a leading cause of blindness in the developed world. The retinal pigment epithelium (RPE) is a critical site of pathology in AMD. Oxidative stress plays a key role in the development of AMD.

Repressed SIRT1/PGC-1α pathway and mitochondrial disintegration in iPSC-derived RPE disease model of age-related macular degeneration

open access: yesJournal of Translational Medicine, 2016
BackgroundStudy of age related macular degeneration (AMD) has been hampered by lack of human models that represent the complexity of the disease. Here we have developed a human in vitro disease model of AMD to investigate the underlying AMD disease ...

Chronic high‐fat diet induces multi‐organ dysfunction and metabolic homeostasis disruption in Macaca fascicularis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
An 18‐month HFD successfully established a translational Macaca fascicularis model replicating key metabolic disorders (MASH, diabetes, cardiac hypertrophy). MASH was determined by liver biopsy histology, the presence steatosis, inflammatory infiltration, hepatocytic ballooning, and fibrosis were considered as MASH; diabetes was diagnosed according to ...

Nanostructured drug delivery systems for posterior segment eye diseases: Strategies to defy ocular barriers

open access: yesBMEMat, EarlyView.
Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

On a new compactification of moduli of vector bundles on a surface, IV: Nonreduced moduli

open access: yes, 2012
The construction for nonreduced projective moduli scheme of semistable admissible pairs is performed. We establish the relation of this moduli scheme with reduced moduli scheme built up in the previous article and prove that nonreduced moduli scheme ...
