Shelf-Stable Formulation for Scalable Laboratory and Field-Based Production of Biocement.

Biocement is an environmentally friendly alternative to traditional cement that is produced via microbially induced calcium carbonate precipitation (MICP) and has great potential to mitigate the environmental harms of cement and concrete use. Current production requires on-site bacterial cultivation and the application of live culture to target materials, lacking the convenience of stable formulas that enable broad adoption and application by nonscientific professionals. Here, we report the development of a dry shelf-stable formulation of , the model organism for biocement production.

Thoracic Aorta Measurement Extraction from Computed Tomography Radiology Reports Using Instruction Tuned Large Language Models.

Chest computed tomography (CT) is essential for diagnosing and monitoring thoracic aortic dilations and aneurysms, conditions that place patients at risk of complications such as aortic dissection and rupture. However, aortic measurements in chest CT radiology reports are often embedded in free-text formats, limiting their accessibility for clinical care, quality improvement and research purposes. In this study, we developed a multi-method pipeline to extract structured aortic measurements from radiology reports, and compared the performance of fine-tuned BERT-based models with instruction-tuned Llama large language models (LLMs).

Complete genome sequence of type strain DSM33.

Here, we present the complete genome sequence of type strain DSM33, a model organism for microbially induced calcium carbonate precipitation. This genome consists of a single 3.3-Mb chromosome and is an improvement upon draft genome sequences currently available in public databases.

Are ICD codes reliable for observational studies? Assessing coding consistency for data quality.

Objective: International Classification of Diseases (ICD) codes recorded in electronic health records (EHRs) are frequently used to create patient cohorts or define phenotypes. Inconsistent assignment of codes may reduce the utility of such cohorts. We assessed the reliability across time and location of the assignment of ICD codes in a US health system at the time of the transition from ICD-9-CM (ICD, 9th Revision, Clinical Modification) to ICD-10-CM (ICD, 10th Revision, Clinical Modification).

Zero-Shot Discovery of High-Performance, Low-Cost Organic Battery Materials Using Machine Learning.

Organic electrode materials (OEMs), composed of abundant elements such as carbon, nitrogen, and oxygen, offer sustainable alternatives to conventional electrode materials that depend on finite metal resources. The vast structural diversity of organic compounds provides a virtually unlimited design space; however, exploring this space through Edisonian trial-and-error approaches is costly and time-consuming. In this work, we develop a new framework, SPARKLE, that combines computational chemistry, molecular generation, and machine learning to achieve zero-shot predictions of OEMs that simultaneously balance reward (specific energy), risk (solubility), and cost (synthesizability).

Open and endovascular treatment of the common femoral artery in a tertiary care center.

Objectives: Endovascular treatment of peripheral arterial disease involving the common femoral artery (CFA) remains controversial. This study compares the perioperative and long-term outcomes of open and endovascular lower extremity revascularization (LER) involving the CFA.

Methods: A retrospective analysis of all patients undergoing LER for peripheral arterial disease in a tertiary care center was performed.

Peak Tricuspid Regurgitation Jet Velocity and Kidney Outcomes in Patients With Heart Failure With Preserved Ejection Fraction.

Introduction: Although venous congestion secondary to elevated pulmonary artery pressure (PAP) has been hypothesized to worsen kidney function, the association of peak tricuspid regurgitation jet velocity (pTRV), a surrogate of PAP, with kidney outcomes remains uncertain in heart failure (HF) with preserved ejection fraction (HFpEF).

Methods: This analysis of the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial analyzed participants with a left ventricular ejection fraction (LVEF) of ≥45% who had pTRV measured by echocardiography at baseline. For the cross-sectional analysis, the association of baseline pTRV with baseline estimated glomerular filtration rate (eGFR) was assessed using linear regression.

Cellular Prion Protein Conformational Shift after Liquid-Liquid Phase Separation Regulated by a Polymeric Antagonist and Mutations.

Liquid-liquid phase separation (LLPS) of intrinsically disordered proteins has been associated with neurodegenerative diseases, although direct mechanisms are poorly defined. Here, we report on a maturation process for the cellular prion protein (PrP) that involves a conformational change after LLPS and is regulated by mutations and poly(4-styrenesulfonic acid--maleic acid) (PSCMA), a molecule that has been reported to rescue Alzheimer's disease-related cognitive deficits by antagonizing the interaction between PrP and amyloid-β oligomers (Aβo). We show that PSCMA can induce reentrant LLPS of PrP and lower the saturation concentration () of PrP by 100-fold.

Rapid Quantification of Protein Secondary Structure Composition from a Single Unassigned 1D C Nuclear Magnetic Resonance Spectrum.

The function of a protein is predicated upon its three-dimensional fold. Representing its complex structure as a series of repeating secondary structural elements is one of the most useful ways by which we study, characterize, and visualize a protein. Consequently, experimental methods that quantify the secondary structure content allow us to connect a protein's structure to its function.

Relmapirazin, a new exogenous filtration marker, and more widespread use of measured GFR.

Plasma or urinary clearance of exogenous filtration markers is required for assessment of measured glomerular filtration rate. Although multiple methods are available, none is widely used because of their complexity, each has measurement error, and standardization is limited. Recently, a study validated the plasma clearance of a new exogenous filtration marker, relmapirazin, which can be detected by its transdermal fluorescence, potentially simplifying the procedure and increasing access to measured glomerular filtration rate.

Intensity Zones and Intensity Thresholds Used to Quantify External Load in Competitive Basketball: A Systematic Review.

Background: Despite widespread use of intensity zones to quantify external load variables in basketball research, the consistency in identifying zones and accompanying intensity thresholds using predominant monitoring approaches in training and games remains unclear.

Objectives: The purpose of this work was to examine the external load intensity zones and thresholds adopted across basketball studies using video-based time-motion analysis (TMA), microsensors, and local positioning systems (LPS).

Methods: PubMed, MEDLINE, and SPORTDiscus databases were searched from inception until 31 January 2023 for studies using intensity zones to quantify external load during basketball training sessions or games.

A baseline structure inventory with critical attribution for the US and its territories.

Leveraging high performance computing, remote sensing, geographic data science, machine learning, and computer vision, Oak Ridge National Laboratory has partnered with Federal Emergency Management Agency (FEMA) to build a baseline structure inventory covering the US and its territories to support disaster preparedness, response, and recovery. The dataset contains more than 125 million structures with critical attribution, and is ready to be used by federal agencies, local government and first responders to accelerate on-the-ground response to disasters, further identify vulnerable areas, and develop strategies to enhance the resilience of critical structures and communities. Data can be freely and openly accessed through Figshare data repository, ESRI's Living Atlas or FEMA's Geodata platform.

Epidemiology and Management of Patients With Kidney Disease and Heart Failure With Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) comprises approximately one-half of all diagnoses of heart failure. There is significant overlap of this clinical syndrome with chronic kidney disease (CKD), with many shared comorbid conditions. The presence of CKD in patients with HFpEF is one of the most powerful risk factors for adverse clinical outcomes, including death and heart failure hospitalization.

An NIR-emitting cyanine dye with pyridinium groups: the impact of regio-bond connection on the photophysical properties.

Two ESIPT-based isomeric cyanines were synthesized with significant bathochromic shift in the optical absorption and emission , along with a very large Stokes shift. Probe 2 exhibited a longer conjugation and better photostability. Both compounds exhibited good selectivity for labeling the plasma membrane of prokaryotic cells and the hair cells of zebrafish.

The Evaluation and Treatment of Somatic Symptom Disorder in Primary Care Practices.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Aqueous Zn-Tetrazine Batteries with Cooperative Zn/H Insertion.

We present the investigation of 1,2,4,5-tetrazine derivatives as low-cost and synthetically modular organic electrode materials in rechargeable aqueous Zn-ion batteries (AZIBs). The substituents at the 3,6-positions of tetrazine were found to be critical for cycling stability. While heteroatom substituents (chloro, methoxy, and pyrazole) lead to the rapid decomposition of electrode materials in the electrolyte, the installation of phenyl groups enhances the cycling stability via π-π stacking.

Robust evidence for bats as reservoir hosts is lacking in most African virus studies: a review and call to optimize sampling and conserve bats.

Africa experiences frequent emerging disease outbreaks among humans, with bats often proposed as zoonotic pathogen hosts. We comprehensively reviewed virus-bat findings from papers published between 1978 and 2020 to evaluate the evidence that African bats are reservoir and/or bridging hosts for viruses that cause human disease. We present data from 162 papers (of 1322) with original findings on (1) numbers and species of bats sampled across bat families and the continent, (2) how bats were selected for study inclusion, (3) if bats were terminally sampled, (4) what types of ecological data, if any, were recorded and (5) which viruses were detected and with what methodology.

Field-Based Planetary Protection Operations for Melt Probes: Validation of Clean Access into the Blood Falls, Antarctica, Englacial Ecosystem.

Subglacial environments on Earth offer important analogs to Ocean World targets in our solar system. These unique microbial ecosystems remain understudied due to the challenges of access through thick glacial ice (tens to hundreds of meters). Additionally, sub-ice collections must be conducted in a clean manner to ensure sample integrity for downstream microbiological and geochemical analyses.

Argatroban Use in Pediatric Patients Supported by Paracorporeal Ventricular Assist Devices.

Direct thrombin inhibitor (DTI) use has been associated with decreased stroke and death rates in children on ventricular assist devices (VADs). Most information about DTI use for children on VADs has focused on bivalirudin with limited data on argatroban. We hypothesized that, compared to unfractionated heparin (UFH), argatroban would be associated with decreased bleeding, stroke, and death rates in children on VADs.

Promoting Science Literacy and Awareness across the Globe: the Role of Scientists as Science Ambassadors.

Science literacy has many personal and societal benefits that allows for better informed decision-making. Although the importance of science literacy is recognized globally, there are many challenges associated with its promotion. Scientists are more frequently engaging with nonscientific audiences through public outreach activities and with increasing support from institutions and professional societies.
