Article Abstract
Accurate age determination is fundamental for investigating fish population dynamics and growth patterns. This study used the lapillus to determine age in populations from an oxbow lake and a stream. Growth patterns were evaluated using three models (the Von Bertalanffy, Gompertz, and Logistic models). The oxbow lake population showed faster growth and longer lifespan (6 years in Dacao Lake; 5 years in Liutiao Stream). Conversely, the stream population displayed a trend toward smaller size and younger age. Both populations exhibited higher Fulton's condition factor in juveniles than in adults. The species exhibited a fast-growth type, with similar fitting results across models. These findings reflect subtle differentiation in life history strategies across habitats, likely related to environmental conditions and competitive pressure from invasive species. These insights into life history underscore the importance of further research to support conservation and sustainable management of this endemic species.

The generation of reactive oxygen species (ROS) through nanozyme-mediated sonocatalytic therapy has demonstrated remarkable therapeutic efficacy in the field of cancer. Nevertheless, it remains a significant challenge for nanozymes with a single catalytic active center to generate sufficient ROS via Fenton or Fenton-like reactions to effectively induce tumor cell death. In order to enhance the catalytic efficacy, we devised and synthesized a multiple active centre and mitochondrial-targeted perovskite nanozyme (NCFP), doped with cobalt (Co) element, and incorporated 4-carboxybutyltriphenylphosphonium bromide (TPP) as a mitochondrial targeting marker for ultrasound (US)-assisted enzyme-like catalytic treatment of tumors.

Background: The utility of routine environmental sampling to monitor the airborne fungal load (AFL) in healthcare settings is uncertain.
Methods: AFL was measured by monthly cultures at a tertiary-care pediatric hospital from November 2018 through October 2023 on eleven units caring for patients at risk for invasive mold infection (IMI). Surveillance for healthcare-associated IMI was conducted for all patients in the healthcare system using locally developed definitions for possible, probable, and definite hospital-onset infections.

Freshwater turtles in the Murray-Darling Basin (MDB), Australia, have declined since the 1970s. Intense nest predation by introduced foxes likely contributes to these declines, disrupting juvenile recruitment needed to sustain populations. Traditional lethal control methods, such as baiting and shooting, have proven inadequate, highlighting the need for innovative conservation strategies.

Traditional fish survey methods are often impractical or invasive in these habitats. This study presents a lightweight, low-cost, T-shaped remote underwater video (RUV) system optimized for fish monitoring in small, high-altitude streams of the European Alps.

Application of anesthetic chemicals in aquaculture is important to minimize stress under normal operations such as handling, transport, and artificial breeding. In the past decade, the preference for natural anesthetics over synthetic ones has increased due to welfare issues regarding fish welfare and food safety. This study investigates the anesthetic efficacy of nutmeg oil () in three freshwater fish species- (Common carp), (Danube sturgeon), and (Rainbow trout)-by modeling behavioral (Induction and recovery times) and hematological responses using artificial neural networks (ANNs).
