Relações planta-animal em ambiente pastoril heterogêneo: padrões de deslocamento e uso de estações alimentares Plant-animal relationships in a heterogeneous pastoral environment: displacement patterns and feeding station use

Revista Brasileira de Zootecnia, 2009
Avaliou-se como o padrão de deslocamento e de utilização de estações alimentares podem ser afetados por alturas de manejo de 4, 8, 12 e 16 cm numa pastagem nativa.

Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, EarlyView.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...

Sward structure and intake of ruminants [PDF]

, 1990
Advocates of mixed grazing have argued that grazing habits of different animal species tend to be complementary rather than exclusively competitive. However there were few objective data for variation in pasture intake and diet selection among species ...

Microalgae Hybrid Biosystem for Enhanced Oral Delivery of Rifaximin in Hepatic Encephalopathy Treatment

Advanced Science, EarlyView.
The microalgae‐nanoparticle hybrid system with antibacterial activity can improve the oral delivery and therapeutic efficiency for hepatic encephalopathy treatment. Oral administration of the system can reduced systemic ammonia levels, enhanced intestinal barrier function, attenuated systemic and neuroinflammation, ameliorated cognitive impairments ...

Relationship between Grazing Jaw Movements and Time Per Bite in Cattle: Effect of Sward Structure and Grazing Methods [PDF]

, 2020
The time per bite is the result of the interaction between mouth morphology, animal behaviour and sward structure (Laca et al. 1994). The time per bite increases with bite mass (Laca et al. 1994), but it has a constant component that is the time required

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

Advanced Science, EarlyView.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

Cobalt Single‐Atom Nanozyme for Enhanced Intestinal Radioprotection and Tumor Radiosensitization via Bidirectional ROS Modulation

Advanced Science, EarlyView.
Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

Variability of sward structure and plant species composition of pastures at low stocking rate [PDF]

, 2003
Grazing at a low stocking rate is considered a promising option to meet both the requirement for a reasonable agronomic output and the maintenance and enhancement of biodiversity.

A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

Advanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Bi-cropping fodder maize in an existing (grass)clover sward [PDF]

, 2006
Organic cultivation of fodder maize is still considered to be difficult. Weed pressure, soil structure degradation during harvest and low nutrient efficiency are some of the common problems.
