Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

open access: yesAdvanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

A marked decrease of HIV 1 viremia in a population of potential transmitters in the 1997-2007 interval reduced the proportion of acute seroconverters but minimally affected the transmission of drug resistance

open access: yes, 2009
BACKGROUND: HIV-1 viremia is a major determinant of HIV-1 transmission at population level. We analysed the relationship between viremia levels of drug-experienced patients as potential transmitters (PTs), number of HIV-1 seroconversions and transmitted ...

An ATP‐Driven N Protein–DDX21 Molecular Switch Dynamically Controls SARS‐CoV‐2 RNA G‐Quadruplex Heterogeneity

open access: yesAdvanced Science, EarlyView.
An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

A General High‐Throughput Mucus Microrheology Platform for Quantitative and Scalable Mucus Phenotyping

open access: yesAdvanced Science, EarlyView.
High‐throughput Differential Dynamic Microscopy measures frequency‐resolved mechanical fingerprints from 3 to 10 μL$\umu{\rm L}$ mucus samples using only a few minutes of operator attention per sample. This automated analysis enables scalable mucus phenotyping for translational research by distinguishing mechanical heterogeneity among donors, disease ...

Transport–Reaction–Signal Coupling in Lateral Flow Assays for Next‐Generation Point‐of‐Care Diagnostics

open access: yesAdvanced Science, EarlyView.
Lateral flow assays are evolving into interdisciplinary, system‐level sensing platforms. Recent innovations are deconstructed through coupled phases of mass transfer, reaction, and signal transduction, revealing interdependence across porous materials, interfacial chemistry, nanolabels, readout devices, and data‐enabled analysis.

Modelling HIV Drug Resistance in Southern Africa. [PDF]

open access: yes, 2021
Southern Africa is the region most affected by HIV globally. In South Africa, for example, the prevalence of HIV reaches 17% among adults. In the early 2000s, the roll-out of antiretroviral therapy (ART), a non-nucleoside reverse transcriptase ...

High prevalence of HIV-1 transmitted drug resistance among therapy-naïve Burmese entering travelers at Dehong ports in Yunnan, China

open access: yesBMC Infectious Diseases, 2018
Background The overall success of Human immunodeficiency virus type 1 (HIV-1) antiretroviral therapy (ART) was heavily challenged upon the occurrence of drug resistance.

LAPTM5 Downregulation‐Driven VAMP8 Phosphorylation Impairs Autophagosome‐Lysosome Fusion and Aggravates Septic Acute Lung Injury

open access: yesAdvanced Science, EarlyView.
LAPTM5 functions as a critical molecular scaffold bridging PGAM5 and VAMP to facilitate PGAM5‐mediated dephosphorylation of VAMP8. This cascade promotes autophagosome‐lysosome fusion, restores impaired autophagic flux, and clears damaged mitochondria, thereby mitigating cellular oxidative stress and systemic inflammation.

Immigration detention centers as torturing environments: Ethical reckonings, radical refusals, and implications for a psychology of resistance

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This paper examines psychologists' ethical dilemmas in immigration detention centers. Using critical psychology, border, and detention scholarship, it highlights psychologists' historical complicity in state violence, from the U.S. Enhanced Interrogation Program to current border regimes.
