Iliopubic rami morphology and its vascular relationships in percutaneous retrograde fixation.

Purpose: Pelvic ring fractures involving the iliopubic rami can cause functional impairment. Percutaneous retrograde fixation is a less invasive procedure when compared to traditional open approaches, however precise anatomical knowledge is crucial for safe screw placement. This study aims to describe the morphology of the iliopubic rami, define a safety corridor for percutaneous screw fixation, specially focusing on the relationships between the iliopubic rami and neurovascular structures.

Enhancing Blue Emission in Poly(‑vinylcarbazole): Synthesis, Functionalization with Anthracene, and Mitigation of Aggregation-Caused Quenching.

This study reports the synthesis and functionalization of poly-(-vinylcarbazole) (PVK) with anthracene units to enhance its blue photoluminescence properties. Structural and thermal analyses confirmed successful incorporation of anthracene moieties into the PVK backbone at an approximate 3:1 ratio of PVK repeat unit to anthracene. Photophysical characterization showed that anthracene-functionalized PVK (PVK-An) retained blue-region emission (432 nm), although with reduced emission efficiency due to π-π stacking interactions.

Advanced nitrogen-doped transition metal oxides decorated with Pt: synthesis and composition strategies for maximised electrochemical performance.

Developing efficient, low-cost catalysts for oxygen reduction and evolution reactions (ORR and OER) is key to advancing metal-air batteries and regenerative fuel cells. In this study, nitrogen-doped binary metal (Mn and Ni) oxides (N-BMOs) and Pt-decorated N-BMOs were synthesised using three methods and tested as ORR and OER catalysts in alkaline media. Their physicochemical properties were characterised by XRD, N-sorption, TEM, and XPS, while their electrochemical performance was evaluated using voltammetry and impedance spectroscopy.

Occurrence of Listeria spp. and Listeria monocytogenes in half-carcasses, meat cuts, equipment, and the environment of bovine slaughterhouses in Brazil.

Human listeriosis is a severe food-borne illness, with fatality rates ranging from 20 to 30 %. In Brazil, despite being an underdiagnosed and underreported disease, the presence of the microorganism in food has been the subject of important studies. However, its occurrence in slaughterhouse environments has received little attention in recent years.

Extracellular Vesicles in Arthropods: Biogenesis, Functions, Isolation Methods and Applications.

Extracellular vesicles (EVs) are membrane-bound nanoparticles secreted by cells that are involved in multiple forms of intercellular communication and show promising potential for biotechnological applications. Arthropod-derived EV research remains relatively fragmented in contrast to the extensively studied mammalian EV field. In this review, we present a comprehensive synthesis of over 100 studies exploring EV biology across arthropods - including insects, arachnids and crustaceans.
