The Effect of Different Copper Discs on the Discharge of Superconducting Coils

open access: yesCrystals, 2022
High temperature superconducting (HTS) magnets often work at high energy density and have slow quench propagation speed, so a quench will present a serious risk to the safety of magnets.

Pericytes change function depending on glioblastoma vicinity: emphasis on immune regulation

open access: yesMolecular Oncology, EarlyView.
Pericytes alter their transcriptome depending on their proximity to the tumor core. In the tumor core, pericytes display a more active state with higher communication strength but with lower immune activation potential and a shift toward extracellular matrix production.

Investigating the statistical relationship between climatic and hydrological variables with Vegetation Dynamics in a dry climate (Case study: Sistan plain in eastern Iran) [PDF]

open access: yesمدیریت بیابان, 2018
Climatic variables are considered as one of the most important factors affecting the spatial-temporal dynamic of vegetation. Nowadays, satellite images are widely used for monitoring the effect of climatic variables fluctuations on vegetation changes ...

Microglia limit brain tumor development by restricting tumor cell proliferation and inducing T‐cell immunity

open access: yesMolecular Oncology, EarlyView.
Microglia (BV2) and IL‐4‐treated BMDMs promote astrocytoma clustering and inhibit tumor growth, not shown in other macrophage cells. In vivo, microglial co‐implantation enhances CD8+ T cell infiltration, elevates Granzyme B, lowers circulating MDSCs, and extends survival only in immune‐competent mice, but not in immune‐deficient mice.

Comparison of the longitudinal and lateral profiles of watercourses using sonar-based methods (ADCP) and hydrological analogy

open access: yesActa Universitatis Carolinae Geographica, 2014
In many cases, a flood wave has a pronounced transforming effect on the channel, and the knowledge of the watercourse longitudinal and lateral profiles is of great importance.

An approach for coherent periodogram averaging of tilt‐series data for improved contrast transfer function estimation

open access: yesFEBS Open Bio, EarlyView.
The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

Development of 4T1 breast cancer mouse model system for preclinical carbonic anhydrase IX studies

open access: yesFEBS Open Bio, EarlyView.
Carbonic anhydrase IX (CAIX) is a well‐recognised therapeutic target and prognostic biomarker in cancer. We developed and characterised a robust murine breast cancer model system that is suitable for CAIX studies in vitro and in vivo—it comprises both CAIX‐positive and CAIX‐negative controls and provides a solid platform for the comprehensive ...

Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families

open access: yesFEBS Open Bio, EarlyView.
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.
