Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

open access: yesMolecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Current Challenges in Understanding and Predicting Transport and Exchange in the Atmosphere over Mountainous Terrain

open access: yesAtmosphere, 2018
Coupling of the earth’s surface with the atmosphere is achieved through an exchange of momentum, energy, and mass in the atmospheric boundary layer. In mountainous terrain, this exchange results from a combination of multiple transport processes, which ...

How Humans Change the Atmosphere [PDF]

open access: yes
This exercise is designed to introduce students to the idea that human activities can alter the chemistry or gaseous composition of the atmosphere, resulting in a variety of impacts on human health and the environment.

Atmosphere-Mediated Superhydrophobicity of Rationally Designed Micro/Nanostructured Surfaces [PDF]

open access: yes, 2019
Superhydrophobicity has received significant attention over the past three decades owing to its significant potential in self-cleaning, anti-icing and drag reduction surfaces, energy-harvesting devices, antibacterial coatings, and enhanced heat transfer ...

Purification and characterization of a thermophilic NAD+‐dependent lactate dehydrogenase from Moorella thermoacetica

open access: yesFEBS Open Bio, EarlyView.
The thermophilic acetogenic model organism Moorella thermoacetica can utilize lactate as substrate. The formation of lactate by reduction of pyruvate is energetically favorable, but the reverse reaction, the oxidation of lactate to pyruvate with NAD+ as electron acceptor is challenging.

Stepwise oxygenation of the Paleozoic atmosphere

open access: yesNature Communications, 2018
Oxygen is essential for animal life, and while geochemical proxies have been instrumental in determining the broad evolutionary history of oxygen on Earth, much of our insight into Phanerozoic oxygen comes from biogeochemical modelling.

Acid Rain [PDF]

open access: yes
Due to the presence of dissolved gases such as carbon dioxide, rainfall is naturally acidic. The release of other gases and chemicals such as sulfur dioxide during the combustion of coal and oil can cause rainfall to become even more acidic, sometimes to

Dimension in a Radiative Stellar Atmosphere [PDF]

open access: yes, 2001
Dimensional scales are examined in an extended 3+1 Vaidya atmosphere surrounding a Schwarzschild source. At one scale, the Vaidya null fluid vanishes and the spacetime contains only a single spherical 2-surface.

Atmospheric corrosion of zinc in coastal atmospheres

open access: yesMaterials and Corrosion, 2019
The atmospheric corrosion of zinc in pure marine coastal atmospheres has not been extensively studied. This paper presents the results obtained in six pure marine atmospheres located at different distances from the seashore in the same coastal area with annual chloride deposition rates of between 47 and 1142 mg · m−2 · day−1.
