Considering the Risks and Costs of Solid Organ Xenotransplantation

Advanced Biology, EarlyView.
This perspective discusses the rationale, risks, and costs of whole‐organ xenotransplantation. It considers alternative strategies to obviate the demand for transplants and optimize allotransplantation systems and practices that do not impose xenotransplantation's harms and risks, and whether they are the most ethical and effective means to increase ...

The development of foraging organization

Attention, Perception, & Psychophysics, 2021
In foraging tasks multiple targets must be found within a single display. The targets can be of one or more types, typically surrounded by numerous distractors. Visual attention has traditionally been studied with single target search tasks but adding more targets to the search display results in several additional measures of interest, such as how ...

LivestockPlus - The sustainable intensification of forage-based agricultural systems to improve livelihoods and ecosystem services in the tropics *

, 2015
As global demand for livestock products (such as meat, milk and eggs) is expected to double by 2050, necessary increases to future production must be reconciled with negative environmental impacts that livestock cause.

Global Seabird Response to Forage Fish Depletion—One-Third for the Birds

Science, 2011
One-third of maximum fish biomass must be available for seabirds to sustain high breeding success. Determining the form of key predator-prey relationships is critical for understanding marine ecosystem dynamics.

Perfect Ultraviolet Absorbers via Disordered Polarizonic Metasurfaces for Multiband Camouflage and Stealth Technologies

Advanced Functional Materials, EarlyView.
An ultrathin polarizonic metasurface achieves multiband camouflage and stealth with near‐perfect ultraviolet (UV) absorption, visible light blending, and infrared signature masking. Leveraging earth‐abundant materials, this design creates a reflective color palette through polarizonic effects, integrating transparent and non‐plasmonic materials.

Characterization of the Core Rumen Microbiome in Cattle during Transition from Forage to Concentrate as Well as during and after an Acidotic Challenge

PLoS ONE, 2013
This study investigated the effect of diet and host on the rumen bacterial microbiome and the impact of an acidotic challenge on its composition. Using parallel pyrosequencing of the V3 hypervariable region of 16S rRNA gene, solid and liquid associated ...

Brain‐Wide Neuroregenerative Gene Therapy Improves Cognition in a Mouse Model of Alzheimer's Disease

Advanced Science, EarlyView.
NeuroD1 mediates brain‐wide astrocyte‐to‐neuron gene therapy conversion in 5xFAD mouse brain. Regenerated neurons can fire action potentials and integrate into pre‐existing neural networks, ultimately improving cognition in AD mice. Abstract Alzheimer's disease (AD) is a progressive and irreversible brain disorder with extensive neuronal loss in the ...

Comprehensive analysis of the circular RNA expression profile and circRNA–miRNA–mRNA network in the goat skin with divergent wool curvature

Animal Research and One Health, EarlyView., 2023
In our study, we conducted circRNA expression profiling of Zhongwei goat skin exhibiting divergent curvature wool phenotypes at two developmental stages using the RNA‐seq. Functional verification assay demonstrated that circRNA8782 regulated fibroblast proliferation.

Assessment of the genetic diversity of cattle by marker genes of dairy productivity

Ветеринария и кормление
Absrtact. The paper presents an assessment of the genetic diversity of cattle by the genes of dairy productivity: kappa-casein (CSN3), beta-casein (CSN2), beta-casein A1A2 (CSN2 A1A2) and genes involved in the regulation of milk production: fatty acid ...

Maximizing Forage Yields in Corn Silage Systems with Winter Grains [PDF]

, 2016
Producing sufficient high quality forage on farms is becoming difficult given current economic and environmental pressures. Farmers are looking for strategies to improve yield and quality of their own forage to reduce the financial burden of purchasing ...
