PISAD: De novo peptide design for target protein with iterative stochastic searching algorithm and docking assessment.

Rapid identification of peptides that bind specifically to a target protein is essential for disease diagnostics and drug development. However, de novo design of peptides without any prior structural knowledge remains a long-standing challenge. Herein, we present Peptide Iterative design with Stochastic Algorithm and Docking (PISAD), a de novo peptide design method, which combines an iterative stochastic searching algorithm with docking assessment.

A Universal Thick Anode for Aqueous and Seawater Energy Storage Devices.

Aqueous and seawater energy storage devices hold great potential for electrical grids application due to safety, affordability, and sustainability. However, their broader deployment has been constrained by the absence of a durable thick anode. Here, the first universal thick anode operating stably across 15 simple-ion and 3 complex-ion systems, including nonmetallic (H, NH ), monovalent (Li, Na, K), multivalent ions (Zn, Ca, Mg, Al), and seawater ions (>5 cations) is reported.

Lanthanide Metal-Organic Framework Flowers for Proteome Profiling and Biomarker Identification in Ultratrace Biofluid Samples.

Identifying effective biomarkers has long been a persistent need for early diagnosis and targeted therapy of disease. While mass spectrometry-based label-free proteomics with trace cell has been demonstrated, deep proteomics with ultratrace human biofluid remains challenging due to low protein concentration, extremely limited patient sample volume, and substantial protein contact losses during preprocessing. Herein, we proposed and validated lanthanide metal-organic framework flowers (MOF-flowers), as effective materials, to trap and enrich protein in biofluid jointly through cation-π interaction and O-Ln coordination.

Regulatory mechanisms of haptoglobin on particulate matter-induced epithelial-to-mesenchymal transition in bronchial epithelial cells.

Background: It has been proposed that repeated exposure of bronchial epithelial cells to atmospheric particulate matter (PM) could disrupt airway epithelial integrity and lead to epithelial-to-mesenchymal transition (EMT) and ultimately airway remodeling. The molecular mechanisms underlying PM-related bronchial epithelial EMT have not yet been elucidated. The aim of this research is to clarify the molecular mechanism of EMT upon PM exposure.

Relationship between urinary tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and lung function: Evidence from NHANES 2007-2012.

Introduction: 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), a metabolite of tobacco-specific nitrosamine (TSNA) 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), is a tobacco-specific carcinogen. Spirometry values (FEV1%, PEF%, etc.) are commonly used as clinical indicators to assess the condition of lung function and the results can be used to diagnose respiratory diseases.

Associations of blood cadmium and lead concentrations with all-cause mortality in US adults with chronic obstructive pulmonary disease.

Background: Some literature indicates an association between exposure to cadmium and lead and the presence of emphysema and chronic bronchitis, which are the two primary components of COPD. Understanding whether there is a potential association between cadmium and lead exposure and higher mortality rates in individuals with COPD could provide profound insights into the long-term effects of these two metal exposures on human health.

Methods: This study included 2024 patients with COPD in the US from the NHANES from 1999 through 2016 who were followed up to 2019.

The oxidative stress-related exposures of diet and lifestyle can be evaluated by the oxidative balance score (OBS), and higher OBS scores indicate more significant antioxidant exposures. But the relationship between OBS and lung health is unknown.

Performance of Machine Learning Algorithms for Predicting Adverse Outcomes in Community-Acquired Pneumonia.

The ability to assess adverse outcomes in patients with community-acquired pneumonia (CAP) could improve clinical decision-making to enhance clinical practice, but the studies remain insufficient, and similarly, few machine learning (ML) models have been developed. We aimed to explore the effectiveness of predicting adverse outcomes in CAP through ML models. A total of 2,302 adults with CAP who were prospectively recruited between January 2012 and March 2015 across three cities in South America were extracted from DryadData.

An Ultrafast, Durable, and High-Loading Polymer Anode for Aqueous Zinc-Ion Batteries and Supercapacitors.

Zn metal has shown promise as an anode material for grid-level energy storage, yet is challenged by dendritic growth and low Coulombic efficiency. Herein, an ultrafast, stable, and high-loading polymer anode for aqueous Zn-ion batteries and capacitors (ZIBs and ZICs) is developed by engineering both the electrode and electrolyte. The anode polymer is rationally prepared to have a suitable electronic structure and a large π-conjugated structure, whereas the electrolyte is manufactured based on the superiority of triflate anions over sulfate anions, as analyzed and confirmed via experiments and simulations.
