Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

Nature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.

Tough Sprouting – Impact of Cadmium on Physiological State and Germination Rate of Soybean Seeds

Acta Societatis Botanicorum Poloniae, 2020
Seed germination is the earliest process in plant development and is crucial for further plant growth and fitness. The process is regulated by various internal and external factors, including soil pollutants such as nonessential metals.

Radiation Shielding and Activation Analyses for Neutron Activation Measurement Facility at Advanced Radiation Technology Institute, Jeongup [PDF]

Journal of Radiation Protection and Research
Background Experiments to measure the neutron activation cross-section using the 30 MeV cyclotron at Advanced Radiation Technology Institute are planned. Neutrons, generated during experiments, will activate the devices and affect the surrounding area of

Neutron activation analysis of multimetallic accumulation in dolomites [PDF]

Hemijska Industrija, 2008
The reason for exploring polymetallic ores, which are found in dolomite structures of the Veovača and Borovica zone near Vareš, lies in the fact that there is very little information about its chemical structure.

T-Cell activation: a queuing theory analysis at low agonist density [PDF]

, 2006
We analyze a simple linear triggering model of the T-cell receptor (TCR) within the framework of queuing theory, in which TCRs enter the queue upon full activation and exit by downregulation.

Molecular brakes regulating mTORC1 activation in skeletal muscle following synergist ablation [PDF]

, 2014
The goal of the current work was to profile positive (mTORC1 activation, autocrine/paracrine growth factors) and negative [AMPK, unfolded protein response (UPR)] pathways that might regulate overload-induced mTORC1 activation with the hypothesis that a ...

NADPH oxidase is involved in regulation of gene expression and ROS overproduction in soybean (Glycine max L.) seedlings exposed to cadmium

Acta Societatis Botanicorum Poloniae, 2017
Cadmium-induced oxidative burst is partially mediated by NADPH oxidase. The aim of the present research was to evaluate the role of NADPH oxidase in soybeans’ response to short-term cadmium stress.

Superintense laser-driven photon activation analysis

Communications Physics, 2021
Photon activation analysis is a non-destructive technique for material characterization that require high photon energies. Here, laser-driven accelerator is considered as a high-energy photon source and its optimization for photon activation analysis ...

Evaluation of Muscle Function by Means of a Muscle-Specific and a Global Index

Sensors, 2021
Gait analysis applications in clinics are still uncommon, for three main reasons: (1) the considerable time needed to prepare the subject for the examination; (2) the lack of user-independent tools; (3) the large variability of muscle activation patterns
