A comprehensive understanding of chemical interactions at the surface of hair represents an important area of research within the cosmetic industry and is essential to obtain new products that exhibit both performance and sustainability. This paper aims at contributing to this research by applying a combination of surface techniques (neutron reflectometry, quartz-crystal microbalance and atomic force microscopy) to study adsorption of surface active ingredients onto hair-mimetic surfaces. The surface of hair is not homogeneous due to chemical and physical damage, and this work focuses on partly damaged hair models, in which both hydrophobic and charged moieties are present.

Microfluidics-based automatic immunofluorescence staining for single-molecule localization microscopy.

Biomed Opt Express

December 2024

State Key Laboratory of Digital Medical Engineering, School of Biomedical Engineering, Hainan University, Sanya 572025, China.

Full automation of single-molecule localization microscopy (SMLM) is crucial for large-scale and high-throughput cellular imaging. It is well-known that SMLM typically consists of three major steps: immunofluorescence (IF) staining, optical imaging, and image processing. Currently, automation in optical imaging and image processing is almost complete; however, the automation of IF staining has been slow to advance, probably due to its complicated experimental operations.

December 2024

Mohn Center for Diabetes Precision Medicine, Department of Clinical Science, University of Bergen, Bergen, Norway.

Amid the advances in genomics, the availability of large reference panels of human haplotypes is key to account for human diversity within and across populations. However, mass spectrometry-based proteomics does not benefit from this information. To address this gap, we introduce ProHap, a Python-based tool that constructs protein sequence databases from phased genotypes of reference panels.

Reevaluation of the Suitability of Xe Nuclear Magnetic Resonance Spectroscopy for Pore Size Determination in Porous Carbon Materials.

J Am Chem Soc

December 2024

Interdisciplinary Graduate School of Engineering Sciences, Kyushu University, 6-1 Kasuga-koen, Kasuga, Fukuoka 816-8580, Japan.

Xenon isotope nuclear magnetic resonance (Xe-NMR) spectroscopy has been widely used to evaluate the pore structure of materials. However, determining how to apply this technique to investigate porous carbon materials is sometimes challenging, partly due to the structural disorder and heterogeneity of the surface properties of these materials, and partly due to the lack of reliable methods for controlling and assessing the density of adsorbed Xe. In this study, we designed and constructed a temperature- and pressure-controllable Xe-NMR system to evaluate the interaction between activated carbon (AC) and adsorbed Xe molecules.

Introduction: Intraamniotic infection (IAI) is one of the main possible complications of preterm prelabor rupture of membranes (PPROM) and can lead to severe consequences for the neonate, such as early onset neonatal sepsis (EONS). Available diagnostic tools for IAI have poor diagnostic performance, which may result in both over- and underdiagnoses of IAI. In a search for better diagnostic tools, we have examined short-term variation (STV) in fetal heart rate.

Beyond a binary theorizing of prosociality.

Proc Natl Acad Sci U S A

December 2024

Department of Computer Science, Aalto University, Espoo 02150, Finland.

Article Synopsis
  • Stylized experiments like the public goods game show that people tend to cooperate more than what traditional economic theories predict.
  • There are two main explanations for this behavior: the prosocial preference hypothesis suggests cooperation is an innate trait, while the confused learner hypothesis argues it's a temporary effect during the game.
  • Our research, which involved large-scale data on the prisoner's dilemma, found that while people do have a tendency to cooperate, it’s not absolute; this understanding challenges oversimplified views of cooperation and has important implications for policy.

Lab Chip

December 2024

Department of Fibre and Polymer Technology, School of Engineering Sciences in Chemistry, Biotechnology and Health, KTH Royal Institute of Technology, Teknikringen 56-58, SE-100 44, Stockholm, Sweden.

Thread-based microfluidics, which rely on capillary forces in threads for liquid flow, are a promising alternative to conventional microfluidics, as they can be easily integrated into wearable textile-based biosensors. We present here advanced textile-based microfluidic devices fabricated by machine stitching, using only commercially available textiles. We stitch a polyester "Coolmax®" yarn with enhanced wicking abilities into both hydrophobic fabric and hydrophobically treated stretchable fabric, that serve as non-wicking substrates.
