Dynamic Culture of Bioprinted Liver Tumor Spheroids in a Pillar/Perfusion Plate for Predictive Screening of Anticancer Drugs.

Recent advancements in three-dimensional (3D) cell culture technologies, such as cell spheroids, organoids, and 3D bioprinted tissue constructs, have significantly improved the physiological relevance of in vitro models. These models better mimic tissue structure and function, closely emulating in vivo characteristics and enhancing phenotypic analysis, critical for basic research and drug screening in personalized cancer therapy. Despite their potential, current 3D cell culture platforms face technical challenges, which include user-unfriendliness in long-term dynamic cell culture, incompatibility with rapid cell encapsulation in biomimetic hydrogels, and low throughput for compound screening.

Nurses' practical contributions to improving healthy and sustainable public spaces: an integrative review.

Objective: to identify knowledge production about nurses' contributions to improving healthy and sustainable public spaces.

Methods: an integrative review carried out in February 2023 in electronic databases. Studies that answered the research question and that were available in full, in Portuguese, English and Spanish, were included.

Thermal and storage stability of novel nutraceuticals combining potential probiotic Limosilactobacillus fermentum strains and freeze-dried jabuticaba [Myrciaria cauliflora (Mart.) O. Berg] peel.

This study evaluated the stability of novel nutraceuticals containing jabuticaba freeze-dried peel (FJP) and a mix of potential probiotic L. fermentum strains [139, 263 and 296 (LfM)] (JM: FJP + LfM; JFM: FJB + LfM + fructooligosaccharides) through determination of thermal stability, viable cell counts, bacterial physiological status, phenolic compound contents, and antioxidant activity during 90 days of storage (11% relative humidity, 4 and 25 ºC). JM and JFM were thermally stable, with satisfactory stability in temperature variations.

Outbreak of ruminal acidosis in cattle caused by the ingestion of hedge lucerne (Desmanthus virgatus L. Willd.) in Northeastern Brazil.

This study describes the epidemiological, clinical, and pathological aspects of an outbreak of ruminal acidosis and ruminitis caused by the ingestion of hedge lucerne (Desmanthus virgatus L.) in 70 cattle in the state of Paraiba, Northeastern Brazil. The herd had been transported from the state of Piauí to Paraiba.

Corneal crosslinking via the Dresden protocol versus the accelerated approach in pediatric patients - a retrospective comparative study.

Purpose: Keratoconus presents certain peculiarities in pediatric patients when compared with adults. The greatest challenge in children is that the disease is more severe and faster in progression. In this retrospective study, we aimed to compare the accelerated and Dresden protocols for corneal crosslinking in patients aged <18 years who were followed-up for at least 12 months.
