Assessing the efficacy and zootechnical performance in laying hens after administration of a 1% aqueous solution of fluralaner (Exzolt) for treating natural infestation by Menacanthus cornutus

Poultry Science
: A brood of laying hens infested with the lice Menacanthus cornutus (Phthiraptera: Menoponidae) evidenced itching, irritation, and damage to their zootechnical performance.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Next‐generation proteomics improves lung cancer risk prediction

Molecular Oncology, EarlyView.
This is one of very few studies that used prediagnostic blood samples from participants of two large population‐based cohorts. We identified, evaluated, and validated an innovative protein marker model that outperformed an established risk prediction model and criteria employed by low‐dose computed tomography in lung cancer screening trials.

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

Molecular 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.

Fire Monitoring, Analysis and Modelling for Climate Change Mitigation and Improved Fire Management

Biodiversidade Brasileira, 2019
Vegetation and peat fires contribute substantially to global emissions of greenhouse gases (GHG). According to latest estimates, net fire emissions amount to about 6% of global fossil fuel GHG emission.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular 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

Fatigue behavior of lubricated Ni-Ti endodontic rotary instruments [PDF]

Fracture and Structural Integrity, 2014
The use of Ni-Ti alloys in the practice of endodontic comes from their important properties such as shape memory and superelasticity phenomena, good corrosion resistance and high compatibility with biological tissues.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

UAV for monitoring the settlement of a landfill

European Journal of Remote Sensing, 2019
Remote-pilot aircraft are developing very rapidly and their potential in the various fields is often still to be fully investigated. The possibility to fly over the areas to be surveyed without the need to access the areas themselves makes the use of ...

Generation Z in Search of Leadership - Model of Intergenerational Leadership for Creating Commitment (MILCC) [PDF]

Cross-Cultural Management Journal
Generation Z is integrating into the fast-changing work world. The effects of its entry are rapid employee turnover, perceptions of no commitment to organizations, and difficulty in understanding employee needs. This article presents a model for creating
