The Wildcat That Lives in Me: A Review on Free-Roaming Cats () in Brazil, Focusing on Research Priorities, Management, and Their Impacts on Cat Welfare.

Domestic cats () currently occupy the 38th place in the Global Invasive Species Database. Free-roaming cats potentially have broad-ranging impacts on wildlife, occupying most terrestrial environments globally as house pets, strays, or feral animals. In Australia, for example, cats are responsible for the decline in many vertebrate populations and extinction of several native mammals.

A New Graphical Method for Displaying Two-Dimensional Echocardiography Results in Dogs: Comprehensive Analysis of Results of Diagnostic Imaging Organized in a BOX (CARDIOBOX).

Introduction And Objective: Rapid and efficient interpretation of echocardiographic findings is critical in clinical decision-making. This study aimed to design and validate a new graphical method, called CARDIOBOX, to represent echocardiographic findings in dogs.

Methods: A prospective, observational, exploratory cohort study was conducted over three years.

Ultrafast synthesis of zirconium-porphyrin framework nanocrystals from alkoxide precursors.

Porphyrinic metal-organic frameworks (MOFs) offer high surface areas and tunable catalytic and optoelectronic properties, making them versatile candidates for applications in phototherapy, drug delivery, photocatalysis, electronics, and energy storage. However, a key challenge for industrial integration is the rapid, cost-effective production of suitable sizes. This study introduces Zr(IV) alkoxides as metal precursors, achieving ultrafast (∼minutes) and high-yield (>90%) synthesis of three well-known Zr-based porphyrinic MOF nanocrystals: MOF-525, PCN-224, and PCN-222, each with distinct topologies.

Assessment of change in end-tidal CO after fluid challenge as a marker of fluid responsiveness as measured by the aortic velocity time integral in healthy anesthetized mechanically ventilated dogs.

Objective: To evaluate if variation in the end-tidal CO partial pressure (∆Petco) after a fluid challenge could predict fluid responsiveness with a sensitivity of 75% and a specificity of 70% in healthy anesthetized and mechanically ventilated dogs.

Design: Diagnostic accuracy study.

Setting: University hospital.

Engineered cell membrane-cloaked metal-organic framework nanocrystals for intracellular cargo delivery.

This investigation demonstrates the development and functionality of cell membrane-cloaked UiO-67 nanosized metal-organic frameworks (NMOFs), which are engineered for precise intracellular delivery of encapsulated cargoes. Utilizing the robust and porous nature of UiO-67, we enveloped these NMOFs with fusogenic cell membrane-derived nanovesicles (FCSMs) sourced from adenocarcinomic human alveolar basal epithelial (A549) cells. This biomimetic coating enhances biocompatibility and leverages the homotypic targeting capabilities of the cell-derived coatings, facilitating direct cytoplasmic delivery and avoiding endolysosomal entrapment.
