Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Comparative analyses of extinction risk in vertebrates

open access: yes, 2009
Measures of current extinction risk imply that a high proportion of the world’s species are threatened with global extinction in the near future, stressing the need for thorough understanding of extinction processes.

Scalable Manufacturing of Radiation‐Tolerant Potentiometric Electrodes: A Systematic Transition from Laboratory to Semiautomated Fabrication

open access: yesAdvanced Engineering Materials, EarlyView.
Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived

Deep-learning-enabled antibiotic discovery through molecular de-extinction

open access: yesNature Biomedical Engineering
Molecular de-extinction aims at resurrecting molecules to solve antibiotic resistance and other present-day biological and biomedical problems. Here we show that deep learning can be used to mine the proteomes of all available extinct organisms for the ...

Biological mass extinctions on planet Earth

open access: yes, 2010
[ES]: Tanto acontecimientos graduales como catastróficos han estado implicados a las extinciones masivas en el planeta Tierra. A pesar de que la mayor extinción masiva, según restos fósiles identificados actualmente, fue la Gran Mortandad (del inglés, “Great Dying”), la mayor de todas las extinciones masivas en el planeta Tierra debió haber sido la ...

A General Cyanine‐Based Platform for Designing Robust Dual‐Channel Near‐Infrared Fluorescent and Photoacoustic Probes

open access: yesAdvanced Functional Materials, EarlyView.
The study presents a general cyanine‐based platform CySN for designing robust dual‐channel near‐infrared fluorescent (NIRF) and photoacoustic (PA) probes with high ratiometric signals change. CySN enables the construction of highly sensitive and selective dual‐channel NIRF/PA probes for both small molecule and enzyme biomarkers (H2O2, esterase ...

Disease extinction in the presence of non-Gaussian noise [PDF]

open access: yes, 2008
We investigate stochastic extinction in an epidemic model and the impact of random vaccinations in large populations. We show that, in the absence of vaccinations, the effective entropic barrier for extinction displays scaling with the distance to the bifurcation point, with an unusual critical exponent.

Unlearning Fear Out-Group Others [PDF]

open access: yes, 2009
Maroney describes a neuroscientific fear-extinction study as preliminary evidence supporting the notion that out-group hostilities might be influenced by biological predispositions.

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
