Hyperhomocysteinemia prevalence among patients with venous thromboembolism

Future Science OA
Aims The objectives of this study were to determine the plasma homocysteine (Hcy) levels and the prevalence of Hyperhomocysteinemia (HHC) in a group of Tunisian patients with deep vein thrombosis (DVT) by comparing it with healthy controls.Methods it was

Deep levels induced optical memory effect in thin InGaN film

AIP Advances, 2018
An optical memory effect is found in a 20 nm InGaN film. With increasing illumination time, photoluminescence (PL) intensity of InGaN rises at first and then falls.

Multi-Level Discovery of Deep Options

CoRR, 2017
Augmenting an agent's control with useful higher-level behaviors called options can greatly reduce the sample complexity of reinforcement learning, but manually designing options is infeasible in high-dimensional and abstract state spaces. While recent work has proposed several techniques for automated option discovery, they do not scale to multi-level

A Deep Level Set Method for Image Segmentation [PDF]

, 2017
This paper proposes a novel image segmentation approachthat integrates fully convolutional networks (FCNs) with a level setmodel. Compared with a FCN, the integrated method can incorporatesmoothing and prior information to achieve an accurate segmentation.Furthermore, different than using the level set model as a post-processingtool, we integrate it ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Non-stationary electronic processes in barrier structures and devices based on them

Технологія та конструювання в електронній апаратурі, 2006
The limits of external influences and conditions (temperature, γ-irradiation) are determined under which the stability of parameters and the concentration of nickel levels are preserved, which is necessary when using nickel as an impurity in ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A simple method for detection and quantitative estimation of deep levels in a barrier layer of AlGaN/GaN HEMT structures by analysis of light induced threshold voltage shift [PDF]

APL Electronic Devices
The characterization of deep levels in AlGaN/gallium nitride (GaN) heterostructures is one of the most important problems in GaN high electron mobility transistor (HEMT) technology.
