Rapid prediction of acute thrombosis via nanoengineered immunosensors with unsupervised clustering for multiple circulating biomarkers.

The recent SARS-CoV-2 pandemic underscores the need for rapid and accurate prediction of clinical thrombotic events. Here, we developed nanoengineered multichannel immunosensors for rapid detection of circulating biomarkers associated with thrombosis, including C-reactive protein (CRP), calprotectin, soluble platelet selectin (sP-selectin), and D-dimer. We fabricated the immunosensors using fiber laser engraving of carbon nanotubes and CO laser cutting of microfluidic channels, along with the electrochemical deposition of gold nanoparticles to conjugate with biomarker-specific aptamers and antibody.

Crosstalk between three CRISPR-Cas types enables primed type VI-A adaptation in .

CRISPR-Cas systems confer adaptive immunity to their prokaryotic hosts through the process of adaptation, where sequences are captured from foreign nucleic acids and integrated as spacers in the CRISPR array, and thereby enable crRNA-guided interference against new threats. While the Cas1-2 integrase is critical for adaptation, it is absent from many CRISPR-Cas loci, rendering the mechanism of spacer acquisition unclear for these systems. Here we show that the RNA-targeting type VI-A CRISPR system of acquires spacers from DNA substrates through the action of a promiscuous Cas1-2 integrase encoded by a co-occurring type II-C system, in a transcription-independent manner.

Frontiers in artificial intelligence-directed light-sheet microscopy for uncovering biological phenomena and multi-organ imaging.

Light-sheet fluorescence microscopy (LSFM) introduces fast scanning of biological phenomena with deep photon penetration and minimal phototoxicity. This advancement represents a significant shift in 3-D imaging of large-scale biological tissues and 4-D (space + time) imaging of small live animals. The large data associated with LSFM requires efficient imaging acquisition and analysis with the use of artificial intelligence (AI)/machine learning (ML) algorithms.

Experience from a Fast-Track Multidisciplinary Clinic Integrating Movement Disorders Neurologists in Normal Pressure Hydrocephalus Evaluation.

In this prospective observational cohort study, we provide preliminary findings from a same-day multidisciplinary fast-tracked normal pressure hydrocephalus (NPH) clinic; incorporating the expertise of movement disorders neurologists, emphasizing the clinical characteristics, consensus classification, and management of patients referred for suspected NPH. We evaluated 111 patients (male/female: 67/44) from April 2022 to May 2023. Based on the multidisciplinary team consensus, 52 (46.

Medication Changes Among Older Drivers Involved in Motor Vehicle Crashes.

Importance: Although older adults may use potentially driver-impairing (PDI) medications that can produce psychomotor impairment, little is known about changes to PDI medication use among older adults from the time before to the time after a motor vehicle crash (MVC).

Objective: To quantify use of and changes in PDI medications among older adults before and after an MVC.

Design, Setting, And Participants: This cohort study used linked Medicare claims and police-reported MVC data on 154 096 person-crashes among 121 846 older drivers.
