We investigated the relationship between the AMBI index and different contamination proxies in an urbanized bay in South America (SE Brazil), and the effect of (a) abundance data transformation and (b) exclusion of low-reliability sites (high SD; low N) on the index' performance. Poor ecological quality and opportunistic species were related to an increase in contaminants concentrations and mud content. Good ecological status and sensitive species (EG I) were mainly related to increased hydrodynamics. Data transformation caused minimal changes to the overall relationships, but exclusion of low-reliability sites improved the relationship between ecological groups and contamination proxies. Our results show that AMBI is robust in detecting effects of different contaminants in the area and reinforce the importance of the index as a tool for coastal management, but local joint efforts are needed to improve and adjust local species classification in ecological groups to improve the index' performance.

Background: Inflammatory back pain is a chronic condition with localized pain, particularly in the axial spine and sacroiliac joints, that is associated with morning stiffness and improves with exercise. YouTube is the second most frequently used social media platform for accessing health information. This study sought to investigate the quality and reliability of YouTube videos on inflammatory back pain (IBP).

Article Synopsis
- - The text discusses the need for improved gait classification methods after a stroke, highlighting that traditional observational analysis has low reliability and accuracy, while data-driven methods may offer a solution.
- - A systematic review evaluated 21 studies on automatic gait classification systems, finding that most achieved high accuracy (80%-100%) but had important methodological flaws, particularly regarding clinical applicability.
- - Recommendations are presented for future development of these systems, emphasizing the importance of clinical relevance and standardized methodologies to better support healthcare professionals in making informed decisions.
Measurement of (Aptamer-Small Target) K Using the Competition between Fluorescently Labeled and Unlabeled Targets and the Detection of Fluorescence Anisotropy.

Registration of fluorescence anisotropy (FA) allows for characterizing the interactions of ligands with aptamers and other receptors under homogeneous conditions without reagent immobilization, prolonged incubations, and product separation. We proposed an approach for aptamer affinity determination by FA taking into account the difference in label fluorescence before and after complexation. The detailed step by step scheme using a native and fluorescently labeled ligand was described and justified in the paper.
