Investigating the mechanism of aluminum resistance conferred by aluminum resistance protein 1. [PDF]
Protein SciAbstract Aluminum does not play any role in essential biological processes, but in acidic conditions it becomes biologically reactive and highly toxic even at low concentrations. Eukaryotes have developed numerous strategies for detoxification, one of which relies on membrane proteins.

Fiber photometry for monitoring cerebral oxygen saturation in freely-moving rodents.
Biomedical Optics Express, 2020 Hemodynamic parameters, such as tissue oxygen saturation and blood volume fraction, are important markers of brain physiology. They are also widely used surrogate markers of electrophysiological activity.

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior
Advanced Physics Research, EarlyView.Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...

Optical and infrared photometry of Arakelian 120 [PDF]
Publications of the Astronomical Society of the Pacific, 1978 Optical and IR photometry of the Seyfert class 1 galaxy Arakelian 120 covering the wavelength range from 0.36 to 3.5 microns is reported. The observed fluxes are found to consist of contributions of starlight from the surrounding galaxy, emission lines, thermal gas continuum, nonthermal radiation, and possible IR emission from dust.

The Spitzer Local Volume Legacy (LVL) global optical photometry [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We present the global optical photometry of 246 galaxies in the Local Volume Legacy (LVL) survey. The full volume-limited sample consists of 258 nearby (D < 11 Mpc) galaxies whose absolute B-band magnitude span a range of -9.6 < M_B < -20.7 mag. A composite optical (UBVR) data set is constructed from observed UBVR and SDSS ugriz imaging, where

Astronomische Nachrichten, EarlyView.ABSTRACT We present new radial velocity measurements of 13 selected intermediate mass stars (2–6 M⊙). The measurements were performed between 29 April and 6 September 2024 at the University Observatory Jena using the échelle spectrograph FLECHAS. The radial velocity of eight stars was found to be constant during our spectroscopic monitoring, namely: 17

Astronomische Nachrichten, EarlyView.ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

Ex vivo liquid core fiber photometry with high-resolution 3D printing
Sensors and Actuators ReportsHigh resolution 3D printing emerges as an alternative to microfabrication due to its fine resolution along with one-step manufacturing. Thus, it is broadly used in many fields, such as biological and chemical applications.
