We described the between–individual variations and compared the diet and morphology of Apareiodon vladii Pavanelli 2006 populations from three rivers in protected areas, South Brazil. Body shape variables and trophic traits were used to describe the morphology of the species and...

Extracellular Vesicles as Emerging Tools in Canine Mammary Tumors: Potential Applications and Perspectives

Breast cancer is one of the most prevalent malignancies in women worldwide and the most common malignant tumor in unspayed female dogs, highlighting the comparative relevance of this disease across these species. The release of EVs is increased in mammary tumors compared to norma...

Ground Vibration due to a Leaking Pipe: Uncertainties in Elastic Wave Propagation and Their Effects

Abstract This work investigates the propagation of elastic waves in soil induced by a leaking buried pipe, emphasizing the influence of uncertainty on ground-surface responses. The analysis is grounded in the underlying wave physics and employs a stochastic modelling framework to...

Comparison of Fogarty and Vollmar thrombectomy for chronic jugular thrombosis in horses

Abstract Background Chronic jugular vein thrombosis may result in persistent venous obstruction and impaired head drainage. Although surgical thrombectomy is performed in selected cases, experimental comparisons between mechanical techniques for chronic thrombus removal in horses...

Smart Coatings Integrating Antimicrobial and Tissue‐Remodeling Functions for Implant Interfaces

AIM: This study aimed to assess the antimicrobial performance and biocompatibility of our drug delivery platform, based on layer-by-layer (LbL) coating incorporating tetracycline (TC) complexed with anionic β-cyclodextrin (TCβCD) and a pH-responsive poly(methacrylic acid) (PMAA)...

Population density and habitat use of the yellow land crab Johngarthia lagostoma on the remote Trindade Island, Brazil: implications for island conservation

Abstract Several land crab species inhabit oceanic islands worldwide, where they often dominate terrestrial arthropod communities, and act as ecosystem engineers. In the South Atlantic, Johngarthia lagostoma is the only gecarcinid species, endemic to Rocas Atoll, Fernando de Noro...

Chronic low back pain and sleep disturbances among agro-industrial and industrial workers: a scoping review

Abstract Aim To map and synthesize the available scientific evidence on the relationship between chronic low back pain and sleep-related outcomes among agro-industrial and industrial workers exposed to high physical demands. Subject and methods A scoping review was conducted foll...

Islands and traversable wormholes

A bstract We study information recovery in black hole evaporation using traversable wormhole protocols in AdS 2 Jackiw-Teitelboim gravity with matter fields coupled to an external bath. By introducing a simple non-local interaction between left and right radiation regions, we gen...

Pharmacological Modulation of Nrf2 Signaling Regulates Oxidative Stress, Inflammation, and Alveolar Bone Loss in Experimental Periodontitis

AIM: To investigate whether pharmacological modulation of Nrf2 signaling influences oxidative stress, inflammatory responses, and periodontal tissue destruction in experimental ligature-induced periodontitis. METHODS: Ligature-induced experimental periodontitis was established in...

Nanosilica increases tolerance to Cu toxicity in soybean seeds by reducing Cu uptake and improving nitrogen use efficiency

The treatment of soybean seeds with copper (Cu) can induce toxicity in seedlings depending on the applied dose and seed storage time after treatment. Silicon (Si) has the potential to mitigate Cu toxicity; however, the underlying mechanisms remain poorly understood. This study pr...

Assessing Water and Sediment Contamination in the Sub-Middle São Francisco River (Brazil): Combining Physicochemical Analyses, Trace Metals, and Allium cepa L. Ecotoxicity

The Sub-middle São Francisco River (Northeast Brazil), a key water resource for regional socioeconomic development, is increasingly threatened by urban, industrial, and intensive irrigated agricultural activities. This study aimed to assess physicochemical parameters, nutrient an...

Gold plays a central role in the global economy as a store of value, a strategic asset, and an important raw material for industrial and technological applications. In mineral exploration, geochemical prospecting allows the delineation of anomalous drainage basins and the identif...

Genome-wide analysis of lipoxygenase genes in Coffea arabica and its diploid progenitors

Lipoxygenase proteins (LOXs) play a crucial role in plant growth, development, and defense notably through their involvement in jasmonic acid (JA) biosynthesis. Here, we aimed to identify and characterize genes encoding lipoxygenases in three coffee species, Coffea arabica, Coffe...

The secret of the saws: historical DNA analysis reveals global genetic diversity loss in a highly threatened species

Abstract Genetic diversity is critical to long-term survival of species but can be eroded by population declines driven by human pressures. Temporal genetic monitoring of threatened species can reveal changes in genetic diversity over time, providing key data for conservation. Sp...
