Article Abstract
Fluorescent chemosensors based on 4-hydroxy cyclopentenones were synthesized by the base catalyzed reaction of 1,5-diphenyl-pentane-1,3,5-trione with benzil and thenil. The molecule obtained by the benzil reaction was found to be useful for the selective detection of Fe by fluorescence turn-off, while the molecule synthesized by the thenil reaction was useful for selective detection of Cu by fluorescent turn-on. Details of the synthesis, complexation mode, nature of binding, reversibility, and pH studies of the two sensors are discussed. The studies revealed that the sensors were suitable for determining Fe and Cu content in real water samples.

Hibernation is an elaborate response strategy employed by numerous mammals to survive in cold conditions that involves active suppression of metabolism. Despite the role of mitochondria as energy metabolism centers during hibernation, the adaptive and evolutionary mechanisms of mitochondrial genes in hibernating animals, like hedgehogs in eulipotyphlan species, are not yet fully understood. In this study, we sequenced and assembled mitochondrial genomes of the hibernating four-toed hedgehog () and the non-hibernating Asian house shrew ().

Objective: This study investigated the relationship of maternal serum uric acid, cystatin C (CysC), and coagulation indices [international normalized ratio (INR) and fibrinogen (FIB)] during pregnancy with clinical features and prognosis of early-onset pre-eclampsia.
Methods: Patients with pre-eclampsia (n = 133) were retrospectively selected, with clinical features and maternal uric acid, CysC, INR, and FIB levels collected. The relationship between clinical features and maternal uric acid, CysC, INR, and FIB was analyzed by Pearson's and Spearman's analyses.
Reference Values for the Dynamic Evaluation Method of Lower Limb Joint Alignment (MADAAMI II) for Dancers.

Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil.
The aim of this study was to propose reference values for the Dynamic Evaluation Method of Lower Limb Joint Alignment (MADAAMI II). During the 2023 Joinville Dance Festival, 346 dancers (315 females and 31 males), aged between 15 and 58 years, with a minimum of 5 years of ballet experience, were randomly evaluated. The dancers were filmed performing the three-step sequence (demi plié, grand plié, and fondu) of the MADAAMI II, in the first foot position, with self-selected turnout and at 120 degrees.

Amylases are key industrial enzymes, and thermostable variants are particularly valuable for robust bioprocessing. This study investigates amylase production via solid-state fermentation (SSF) using non-sterile potato peel as substrate, comparing the performance of the autochthonous microbial population with that of the inoculated fungus Thermomyces lanuginosus. Non-inoculated batch reactors reached maximum productivities of 3920 U g¹DM day¹, more than double of the inoculated ones (1823 U g¹DM day¹), highlighting the potential of native thermophiles.

The design of efficient and user-friendly methods for nitrite detection is of great significance owing to its critical role in food safety and environmental protection. Herein, we report a novel cobalt single-atom nanozyme (CoN SA) featuring a highly asymmetric CoN coordination environment. This structural configuration stabilizes high-spin Co species and significantly enhances the oxidase-like activity.
