AI Article Synopsis

  • * Recent interdisciplinary research has shed light on how flow affects various bacterial responses, including adhesion, movement, colonization, and gene expression.
  • * The review focuses on four different bacterial species and outlines experimental methods to study their behavior in flow, highlighting that not all responses are due to shear forces and emphasizing flow-sensitive signaling in bacteria.

Article Abstract

Bacteria thrive in environments rich in fluid flow, such as the gastrointestinal tract, bloodstream, aquatic systems, and the urinary tract. Despite the importance of flow, how flow affects bacterial life is underappreciated. In recent years, the combination of approaches from biology, physics, and engineering has led to a deeper understanding of how bacteria interact with flow. Here, we highlight the wide range of bacterial responses to flow, including changes in surface adhesion, motility, surface colonization, quorum sensing, virulence factor production, and gene expression. To emphasize the diversity of flow responses, we focus our review on how flow affects four ecologically distinct bacterial species: Escherichia coli, Staphylococcus aureus, Caulobacter crescentus, and Pseudomonas aeruginosa. Additionally, we present experimental approaches to precisely study bacteria in flow, discuss how only some flow responses are triggered by shear force, and provide perspective on flow-sensitive bacterial signaling.

Proposal: Bold New Indications for Transcatheter Pulmonary Flow Restrictors.

Pediatr Cardiol

January 2025

Pediatric Heart Center, Johann-Wolfgang-Goethe University Clinic, Theodor-Storm-Kai 7, 60596, Frankfurt, Germany.

This proposal presents a proof of concept for the use of pulmonary flow restrictors (PFRs) based on MVP™-devices, drawing from clinical experience, and explores their potential role in the management of newborns with hypoplastic left heart syndrome (HLHS), other complex left heart lesions, and infants with end-stage dilated cardiomyopathy (DCM). At this early stage of age, manually adjusted PFRs can be tailored to patient's size and hemodynamic needs. Although currently used off-label, PFRs have substantial potential to improve outcomes in these vulnerable patient populations.

Unipolar Barrier Photodetectors Based on Van Der Waals Heterostructure with Ultra-High Light On/Off Ratio and Fast Speed.

Adv Sci (Weinh)

January 2025

Information Materials and Intelligent Sensing Laboratory of Anhui Province, Key Laboratory of Structure and Functional Regulation of Hybrid Materials of Ministry of Education, Institutes of Physical Science and Information Technology, Anhui University, 111 Jiu Long Road, Hefei, 230601, China.

Unipolar barrier architecture is designed to enhance the photodetector's sensitivity by inducing highly asymmetrical barriers, a higher barrier for blocking majority carriers to depressing dark current, and a low minority carrier barrier without impeding the photocurrent flow through the channel. Depressed dark current without block photocurrent is highly desired for uncooled Long-wave infrared (LWIR) photodetection, which can enhance the sensitivity of the photodetector. Here, an excellent unipolar barrier photodetector based on multi-layer (ML) graphene (G) is developed, WSe, and PtSe (G-WSe-PtSe) van der Waals (vdW) heterostructure, in which extremely low dark current of 1.

Optimized methods for scRNA-seq and snRNA-seq of skeletal muscle stored in nucleic acid stabilizing preservative.

Commun Biol

January 2025

Center for Research on Genomics and Global Health, National Human Genome Research Institute, National Institutes of Health, Bethesda, MD, 20892, USA.

Single cell studies have transformed our understanding of cellular heterogeneity in disease but the need for fresh starting material can be an obstacle, especially in the context of international multicenter studies and archived tissue. We developed a protocol to obtain high-quality cells and nuclei from dissected human skeletal muscle archived in the preservative Allprotect® Tissue Reagent. After fluorescent imaging microscopy confirmed intact nuclei, we performed four protocol variations that compared sequencing metrics between cells and nuclei enriched by either filtering or flow cytometry sorting.

Development of lateral flow immunochromatographic assay with Anti-Pythium insidiosum antibodies for point-of-care testing of vascular pythiosis.

Sci Rep

January 2025

Center of Excellence for Antimicrobial Resistance and Stewardship, Department of Microbiology, Faculty of Medicine, Chulalongkorn University, Bangkok, 10330, Thailand.

The pathogenic oomycete Pythium insidiosum causes a fatal infectious illness known as pythiosis, impacting humans and certain animals in numerous countries in the tropics and subtropics. Delayed diagnosis is a primary factor contributing to the heightened morbidity and mortality associated with the disease. Several new serodiagnostic methods have been developed to improve the identification of pythiosis.
