To facilitate on-site detection by nonspecialists, there is a demand for the development of portable "sample-to-answer" devices capable of executing all procedures in an automated or easy-to-operate manner. Here, we developed an automated detection device that integrated a magnetofluidic manipulation system and a signal acquisition system. Both systems were controllable via a smartphone.

Background: Rotator cuff repairs may fail because of compromised blood supply, suture anchor pullout, or poor fixation to bone. To augment the repairs and promote healing of the tears, orthobiologics, such a platelet-rich plasma (PRP), and biologic scaffolds have been applied with mixed results. Adipose allograft matrix (AAM), which recruits native cells to damaged tissues, may also be a potential treatment for rotator cuff tears.

Department of Tuberculosis Diseases, The Sixth People's Hospital of Dongguan, Dongguan, GuangDong, China.
Background: Exosome is a small extracellular vesicle with a diameter of 30 to 150 nm that is secreted by cells. Mtb and other bacteria can also secrete extracellular vesicles, which carry characteristics and information about the pathogen. Here, we compare the concentration of exosomes and the Mtb antigen in exosomes of tuberculosis patients aiming to evaluate whether exosomes can be used as diagnostic markers of tuberculosis at different stages.

Increasing soil salinity causes significant crop losses globally; therefore, understanding plant responses to salt (sodium) stress is of high importance. Plants avoid sodium toxicity through subcellular compartmentation by intricate processes involving a high level of elemental interdependence. Current technologies to visualize sodium, in particular, together with other elements, are either indirect or lack in resolution.

January 2025
Danish Dementia Research Centre, Department of Neurology, Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark.
Background: Little is known about confounding factors influencing Alzheimer's disease (AD) blood biomarker concentrations.
Objective: The objective of this systematic review was to explore the available evidence for the influences of ethnicity and race on AD blood biomarker concentrations.
Methods: We conducted a comprehensive systematic search in PubMed and Web of Science databases spanning from inception until 15 June 2023.
