Exactly solvable 1D model explains the low-energy vibrational level structure of protonated methane.

Chem Commun (Camb) 2021 Apr 16. Epub 2021 Apr 16.

Laboratory of Molecular Structure and Dynamics, Institute of Chemistry, ELTE Eötvös Loránd University, Pázmány Péter sétány 1/A, Budapest H-1117, Hungary and MTA-ELTE Complex Chemical Systems Research Group, P.O. Box 32, Budapest 112 H-1518, Hungary.

A new one-dimensional model is proposed for the low-energy vibrational quantum dynamics of CH5+ based on the motion of an effective particle confined to a 60-vertex graph Γ60 with a single edge length parameter. Within this model, the quantum states of CH5+ are obtained in analytic form and are related to combinatorial properties of Γ60. The bipartite structure of Γ60 gives a simple explanation for curious symmetries observed in numerically exact variational calculations on CH5+. Read More

Revealing Conformational Transition Dynamics of Photosynthetic Proteins in Single-Molecule Electrical Circuits.

J Phys Chem Lett 2021 Apr 15:3853-3859. Epub 2021 Apr 15.

Beijing National Laboratory for Molecular Sciences State Key Laboratory for Structural Chemistry of Unstable and Stable Species, College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, P. R. China.

The function of proteins depends on their structural flexibility and conformational change. By utilizing silicon-nanowire-based single-molecule electrical circuits, here we present a label-free real-time measurement method that can directly monitor conformational changes of a photosynthetic LH1-RC complex, reaching the ultimate goal of analytic chemistry. These results manifest that the conformation of the LH1-RC complex vibrates among four conformations with strong temperature dependence. Read More

Amanda Konradi

BMC Pediatr 2021 Apr 14;21(1):173. Epub 2021 Apr 14.

Department of Sociology, Loyola University Maryland, 4501 North Charles St., Baltimore, MD, 20210, USA.

Background: Stigma, both enacted and internalized, is part of the illness experience of many chronic conditions / diseases and has been found to increase psychological distress, lower self-esteem, and impact social engagement lowering quality of life (QOL). Stigma among pediatric patients is of particular concern due to its potential impact on identity formation. Using patient data from the online FD/MAS Alliance Patient Registry (FDMASAPR), this study seeks to 1) determine levels of enacted and self-stigma in a pediatric population of fibrous dysplasia (FD) / McCune Albright syndrome (MAS) patients and 2) to explore the relationship between stigma and anxiety and depression.

Describing Droplet Motion on Surface-Textured Ratchet Tracks with an Inverted Double Pendulum Model.

Langmuir 2021 Apr 14. Epub 2021 Apr 14.

Mechanical Engineering Department, Bilkent University, Ankara 06800, Turkey.

We describe the motion of a droplet on a textured ratchet track using a nonlinear resonator model. A textured ratchet track is composed of a semicircular pillar array that induces a net surface tension local gradient on a droplet placed on it. When a vertical vibration is applied, hysteresis is overcome, and the droplet moves toward the local lower energy barrier; however, due to the repetitive structure of texture, it keeps moving until the end of the track.

Bayesian semiparametric meta-analytic-predictive prior for historical control borrowing in clinical trials.

Stat Med 2021 Apr 13. Epub 2021 Apr 13.

Takeda Pharmaceuticals, Cambridge, Massachusetts, USA.

When designing a clinical trial, borrowing historical control information can provide a more efficient approach by reducing the necessary control arm sample size while still yielding increased power. Several Bayesian methods for incorporating historical information via a prior distribution have been proposed, for example, (modified) power prior, (robust) meta-analytic predictive prior. When utilizing historical control borrowing, the prior parameter(s) must be specified to determine the magnitude of borrowing before the current data are observed. Read More

Detection of pathogenic bacteria by magneto-immunoassays: a review.

Authors:
Eugen Gheorghiu

J Biomed Res 2020 Dec 25:1-7. Epub 2020 Dec 25.

International Centre of Biodynamics, Bucharest 060101, Romania.

Magnetic particle-based immunoassays are widely used in microbiology-related assays for both microbial capture, separation, analysis, and detection. Besides facilitating sample operation, the implementation of micro-to-nanometer scale magnetic beads as a solid support potentially shortens the incubation time (for magnetic immuno capture) from several hours to less than an hour. Analytical technologies based on magnetic beads offer a rapid, effective and inexpensive way to separate and concentrate the target analytes prior to detection. Read More
