Highly Fluorescent Bio-Synthesized Carbon Quantum Dots for Latent Fingerprint Detection.

This study introduces an innovative approach to high-resolution latent fingerprint detection using carbon quantum dots (CQDs) biosynthesized from spent coffee grounds, enhanced with nitrogen doping. Conventional fingerprinting methods frequently use hazardous chemicals and are costly, highlighting the need for eco-friendly, affordable alternatives that preserve detection quality. The biosynthesized nitrogen-doped CQDs exhibit strong photoluminescence and high stability, offering a sustainable, effective alternative for fingerprint imaging.

Brazilian version of the Kerlan-Jobe orthopedic clinic shoulder and elbow score: translation and cross-cultural adaptation.

Background: The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is commonly used to assess the functional status of athletes with conditions affecting the shoulder and elbow. However, a Brazilian Portuguese version of the KJOC questionnaire is currently unavailable.

Objectives: This study aimed to develop a Brazilian Portuguese version of the KJOC questionnaire.

Assessment of detraining through a six-minute walk test in patients with heart disease.

Background: Detraining can partially or completely reduce training-induced metabolic adaptations. However, the duration for which the rehabilitation effects persist after detraining, especially in patients with heart disease, remains unclear.

Objectives: To evaluate the principle of reversibility/detraining in patients with heart disease via the 6-minute walk test (6MWT) after a period of rest.

Correction: Physical activity and sedentary behavior levels among individuals with mental illness: A cross-sectional study from 23 countries.
