Neuronal traveling waves form preferred pathways using synaptic plasticity.

Traveling waves of neuronal spiking activity are commonly observed across the brain, but their intrinsic function is still a matter of investigation. Experiments suggest that they may be valuable in the consolidation of memory or learning, indicating that consideration of traveling waves in the presence of plasticity might be important. A possible outcome of this consideration is that the synaptic pathways, necessary for the propagation of these waves, will be modified by the waves themselves.

Seroepidemiology of human leptospirosis in the Dominican Republic: A multistage cluster survey, 2021.

Little is known about the epidemiology of leptospirosis in the Dominican Republic, the second most populous country in the Caribbean. We report on findings from a multi-stage household survey across two regions in the country that reveals a previously under-estimated burden of human Leptospira infection. Our findings, based on the reference-standard microscopic agglutination test, indicate a complex picture of serogroup diversity, spatial heterogeneity in infection and risk, and a marked discrepancy between reported cases and serologically estimated infections.

Towards Automated Semantic Segmentation in Mammography Images for Enhanced Clinical Applications.

Mammography images are widely used to detect non-palpable breast lesions or nodules, aiding in cancer prevention and enabling timely intervention when necessary. To support medical analysis, computer-aided detection systems can automate the segmentation of landmark structures, which is helpful in locating abnormalities and evaluating image acquisition adequacy. This paper presents a deep learning-based framework for segmenting the nipple, the pectoral muscle, the fibroglandular tissue, and the fatty tissue in standard-view mammography images.

Efficacy of 30% silver diamine fluoride compared to atraumatic restorative treatment in arresting dentin caries lesions in preschoolers: a randomized clinical trial.

Objective: To compare the efficacy of silver diamine fluoride (SDF) and atraumatic restorative treatment (ART) in arresting caries lesions. Variables such as treatment time, adverse effects/parental aesthetic perception, anxiety and patients' behavior were also evaluated.
