New Data on Distribution and Population Number of Large Raptors in Northern Usturt Within Atyrau Province, Kazakhstan

open access: yesПернатые хищники и их охрана, 2020
In May and June 2018 and June 2019 we surveyed breeding populations of large raptors (principally Golden Eagle Aquila chrysaetos, Eastern Imperial Eagle Aquila heliaca, Steppe Eagle Aquila nipalensis, Long-Legged Buzzard Buteo rufinus, Saker Falcon Falco

Survey for Hemoparasites in Imperial Eagles (Aquila heliaca), Steppe Eagles (Aquila nipalensis), and White-tailed Sea Eagles (Haliaeetus albicilla) from Kazakhstan [PDF]

open access: yesJournal of Wildlife Diseases, 2004
Prevalence of hemoparasites has been investigated in many avian species throughout Europe and North America. Basic hematologic surveys are the first step toward evaluating whether host-parasite prevalences observed in North America and Europe occur elsewhere in the world. We collected blood smears from 94 nestling imperial eagles (Aquila heliaca), five

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Eagle Nesting Groups in the Important Bird Area “Donyz-Tau cliff faces” in 2022

open access: yesПернатые хищники и их охрана, 2023
The Important Bird Area (IBA) “Donyz-Tau cliff faces” (KZ019), with an area of 387,110 hectares, has been allocated by I.V. Karyakin (2008) based on survey results in 2003–2006. Survey showed several globally threatened and biome-specific species nesting

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase

open access: yesAdvanced Science, EarlyView.
Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

Temporal Interference Stimulation Enhances Neural Regeneration

open access: yesAdvanced Science, EarlyView.
Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.

Landscape alteration affects the demography of an endangered avian predator by reducing the habitat quality

open access: yesAvian Research, 2022
Habitat transformation is identified as major threat to biodiversity loss globally, affecting threatened raptors. Changes in land use can alter the abundance and distribution of birds of prey by affecting habitat availability and quality.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Wintering Birds in Northern Saudi Arabia: February 2009 [PDF]

open access: yes, 2011
The northern plains of Saudi Arabia are an area of approximately 231,000 km2, or roughly equivalent to the size of the whole of the United Kingdom. During previous ABBA Surveys in this area in late winter and spring significant numbers of wintering ...
