Behavioral and Morphological Adaptations of Tortoise Tick Hyalomma aegyptium to Testudo graeca: Evidence for Complex Evolutionary History

open access: yesEcology and Evolution
In vector arthropods, the host relationship plays a central role in population dynamics and is crucial for determining the current and future course of vector ecology and the eco‐epidemiology of vector‐borne diseases, particularly under the influence of ...

Subpicosecond $X$ rotations of atomic clock states

open access: yes, 2018
We demonstrate subpicosecond-time-scale population transfer between the pair of hyperfine ground states of atomic rubidium using a single laser-pulse. Our scheme utilizes the geometric and dynamic phases induced during Rabi oscillation through the fine ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Morphometry and retention time as forcing functions to establishment and maintenance of aquatic macrophytes in a tropical reservoir

open access: yesBrazilian Journal of Biology
Macrophytes may constitute an important resource for several chemical, physical and biological processes within aquatic ecosystems. This study considers that in tropical reservoirs with low retention time and with low values of shoreline development (DL),

A natural hybrid between rudd Scardinius erythrophthalmus and bream Abramis brama from Lake Akersvann, SE Norway

open access: yesFauna Norvegica, 1985
An examination of 83 cyprinid specimens collected in Lake Akersvann, SE Norway in Sept. 1984 and in June and Sept. 1985 showed these to be natural hybrids between Scardinius erythrophthalmus and Abramis brama.

Neutral evolution and turnover over centuries of English word popularity [PDF]

open access: yes, 2017
Here we test Neutral models against the evolution of English word frequency and vocabulary at the population scale, as recorded in annual word frequencies from three centuries of English language books. Against these data, we test both static and dynamic

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Introduction of Atlantic salmon Salmo salar L. to the river Akerselv, Oslo

open access: yesFauna Norvegica, 1986
In 1981 Carlintagged Atlantic salmon smolts from the river Imsa and river Sandvikselv stocks, and in 1984 smolts from the river Loneelv stock were released in the river Akerselv. The smolts left the river and the inner Oslofjord few weeks after release.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve
