Observations of sea ice and icebergs from satellite radar altimeters [PDF]

open access: yes, 1984
Satellite radar altimeters can make useful contributions to the study of sea ice both by enhancing observations from other instruments and by providing a unique probe of ocean-ice interaction in the Marginal Ice Zone (MIZ).

Characterization of WAC interactions with R2TP and TTT chaperone complexes linking glucose and glutamine availability to mTORC1 activity

open access: yesFEBS Open Bio, EarlyView.
TTT and R2TP chaperone complexes are required for the assembly and activation of mTORC1. WAC directly interacts with components of TTT, R2TP, and mTORC1, and these interactions are affected by the availability of glucose and glutamine, correlating with changes in mTORC1 activity.

Shipping Through Sea Ice: Impacts on Marine Habitats and Best Practices [PDF]

open access: yes, 2017
As the result of Arctic climate change and an increase in shipping season length, there is a growing interest in Arctic shipping operations. Sea ice serves as an important habitat for marine mammals, therefore, shipping through sea ice could lead to ...

Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

open access: yesFEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

An optimized protocol to detect high‐throughput DNA methylation from custom targeted sequences on 96 samples simultaneously

open access: yesFEBS Open Bio, EarlyView.
Workflow of a high‐throughput technology for epigenotyping of differentially methylated CpGs in specific regions of the genome. The protocol works with small amounts of DNA extracted from blood or semen. The protocol consists of both enzymatic conversion of unmethylated cytosines and capture by hybridization with a custom panel.

Radiative Heating of an Ice-Free Arctic Ocean [PDF]

open access: yes, 2019
During recent decades, there has been dramatic Arctic sea ice retreat. This has reduced the top-of-atmosphere albedo, adding more solar energy to the climate system.

Downregulation of sST2, a decoy receptor for interleukin‐33, enhances subcutaneous tumor growth in murine pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Subcutaneous implantation of murine Panc02 pancreatic cancer cells depleted of sST2, a soluble decoy receptor for the proinflammatory interleukin‐33 (IL‐33), leads to a decreased number of GLUT4‐positive cancer‐associated adipocytes, reduced levels of the anti‐inflammatory molecule adiponectin, increased phosphorylation of IκBα, elevated Cxcl3 ...

Review of Arctic sea-ice records over the last millennium from modern, historical, and proxy data sources

open access: yesArctic, Antarctic, and Alpine Research
Sea-ice loss and increasing unpredictability have disturbed and harmed Arctic peoples and ecosystems. In addition, studies demonstrate that sea ice plays a key role in climate variability and air–sea CO2 exchanges. Sea-ice data sets provide environmental

Phosphomimetic mutations near active sites of proteins in Thermus thermophilus suggest a widespread regulatory mechanism

open access: yesFEBS Open Bio, EarlyView.
In Thermus thermophilus, more than half of the phosphorylation sites identified by proteomic analysis are located near the active site. All phosphomimetic mutants of phosphosites of six enzymes belonging to different families showed severely reduced activity compared with the wild‐type, particularly in the turnover number.
