Theoretical Estimate of Energy Balance and Nutritional Needs of the Population of Russian Sturgeon Acipenser gueldenstaedtii in the Caspian Sea

Croatian Journal of Fisheries, 2019
Individual and group annual rations of Russian sturgeon Acipenser gueldenstaedtii are calculated on the basis of models describing the energy balance and dynamics of the number of fish generations with natural mortality depending on age. The structure of

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Rational Underdevelopment* [PDF]

The Scandinavian Journal of Economics, 2007
AbstractWe propose a two‐region two‐sector model of uneven development, where technological change benefits either the lagging or the leading region. In this framework interregional transfers may lead to persistent underdevelopment; by raising wages, transfers reduce the chance of the backward region adopting a new technology and taking off.

Interference of ATP‐Binding Cassette Transporter by Functional Nano‐Delivery System for High Efficiency Management of Insecticide‐Resistant Nilaparvata lugens

Advanced Science, EarlyView.
A ZIF‐90 nanocarrier delivers dinotefuran and suppresses NlABCG3 and NlABCH1 in resistant Nilaparvata lugens. This system combines pH/ATP‐triggered release with enhanced foliar retention, improving efficacy while sparing honeybees and promoting rice growth, offering a promising resistance‐breaking strategy.

Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy

Advanced Science, EarlyView.
This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

U.S. Agriculture, Biofuel Markets, and Trade: Challenges and Opportunities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using an enhanced Computable General Equilibrium (CGE) model (GTAP‐BIO), this study assesses how the expansion in demand for Electric Vehicles (EVs) and the reduction in exports of agricultural products induced by trade disputes negatively affect US agriculture.

Video and Text‐Based Supplemental Health Information and Consumer Willingness to Pay for Nutrient‐Enhanced Eggs

Agribusiness, EarlyView.
ABSTRACT Nutritional information is very important in the food choices of consumers. However, when they are too scientific or technical, they have the potential to confuse consumers, resulting in information asymmetry and dissuading them from making beneficial choices.

Supporting Aged Care Worker Wellbeing: A Qualitative Document Analysis of the Strengthened Aged Care Quality Standards

Australian Journal of Social Issues, EarlyView.
ABSTRACT Aged care work is physically and emotionally demanding. Workers can feel disempowered, vulnerable and at increased risk of experiencing work‐related stress. This in turn can result in sub‐optimal care and staff shortages. This study aimed to investigate what provisions exist within Australia's strengthened Aged Care Quality Standards to ...
