Immunomagnetic‐MXene Bifunctional Probes for Ultrasensitive and Specific Terahertz Metasensing of Tumor‐Derived Exosomes

open access: yesAdvanced Science, EarlyView.
An immunomagnetic‐MXene bifunctional probe integrated with THz metamaterials enables ultrasensitive and specific detection of pancreatic cancer‐derived exosomes. Dual biomarker recognition ensures high specificity, while MXene signal amplification achieves a detection limit of 647 particles mL−1.

EphB1 Receptor Blockade Augments Morphine Antinociception via Inhibiting GRK2‐Mediated µ‐Opioid Receptor Internalization

open access: yesAdvanced Science, EarlyView.
Administration of opioids activates ephrinB2‐EphB1 receptor signaling. Activated EphB1 receptors induce GRK2‐mediated phosphorylation of MOR at Ser375, which initiates the internalization of MOR and reduces opioid antinociception at the behavioral level. ABSTRACT Opioids are the primary treatment for severe pain in clinical practice.

The Effect of a Bottleneck on Genomic Variation: a Study of the White-Tailed Eagle in Iceland [PDF]

open access: yes, 2018
As a part of a PhD project we are investigating the genomics of the current Icelandic white-tailed eagle population, in comparison with genomic data from other larger and outbred populations, and to historic samples from before the bottleneck in Iceland.

Anthropogenic influence on the interaction between the white-tailed eagle Haliaeetus albicilla and the common guillemot Uria aalge on the island of Stora Karlsö in the Baltic Sea

open access: yes, 2021
In 2020, the ‘anthropause’ due to the spread of the global pandemic COVID-19 interfered with the biotic interactions on the island of Stora Karlsö, in the Baltic Sea.

3D Bioprinted Blood–Brain–Tumor Barrier Spheroid‐Based In Situ Evaluation of Anticancer Compounds Against Glioblastoma: ROS‐Producing Ruthenium as a Potential Therapeutic Candidate

open access: yesAdvanced Science, EarlyView.
The blood–brain–tumor barrier (BBTB) penetration by anticancer drugs and their effects on glioblastoma (GBM) is assessed using 3D bioprinted‐spheroids. Anticancer drug‐induced U‐87 MG cell death is quantified through in situ imaging of spheroids using a cancer cell death probe. The Ru compound, a partial P‐gp substrate, induces greater tumor‐cell death

Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

Migration and Nesting of Eagles in the Upper Reaches of Angara River

open access: yesПернатые хищники и их охрана, 2018
The work was carried out in 2009–2018 in the sources of Angara river and adjacent areas, using commonly accepted methods of recording birds, adapted to local conditions (Ravkin, Chelintsev, 1990; Melnikov, 2016).

A Novel Reactive Oxygen Species‐Responsive Bone‐Targeted Nanoplatform Based on Cloperastine Attenuates Ovariectomy‐Induced Bone Loss by Inhibiting Osteoclast Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
Cloperastine suppresses osteoclastogenesis by inhibiting PGC1β‐mediated oxidative phosphorylation. Its incorporation into a ROS‐responsive, Asp8‐modified nanoplatform enhances skeletal accumulation. The resulting Clo/Asp8‐PMK‐MCs combine cloperastine‐mediated antiresorptive activity with carrier‐mediated osteogenic activity to attenuate OVX‐induced ...

Restoration of sea eagle population: A review

open access: yesCurrent Zoology, 2009
The population density of the white-tailed sea eagle Haliaeetus albicilla is very low in many countries. In last twenty years, the sea eagle population in South Bohemia was restored by strict protection subsidized by reintroduction.
