Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Nonlinear H∞ Optimal Control Scheme for an Underwater Vehicle with Regional Function Formulation [PDF]

open access: yes, 2013
A conventional region control technique cannot meet the demands for an accurate tracking performance in view of its inability to accommodate highly nonlinear system dynamics, imprecise hydrodynamic coefficients, and external disturbances.

Performance comparison of CD4 T-cell count instruments based on data from the national proficiency testing program in China, 2016–2023

open access: yesBMC Infectious Diseases
Background The number of CD4 T cells is an important indicator of immune status in people living with HIV (PWH). In China, numerous CD4 count instruments have been approved; however, no studies have been conducted to systematically compare the ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Mechatronics Application to Solar Tracking [PDF]

open access: yes, 2011
The purpose of this was to design and implement a two-axis solar tracking system utilizing the National Instruments C-Rio real time controller. In order to accomplish this a prototype was modeled in CAD. This prototype used two 12 V DC motors to change a

The differences in microbial communities and Tick-Borne pathogens between Dermacentor marginatus and Hyalomma asiaticum collected from the Northwestern Xinjiang Uygur Autonomous Region, China

open access: yesBMC Infectious Diseases
Background Ticks are important vectors for the transmission of pathogens, including viruses, bacteria, and protozoa. This study investigated the microbial communities and the dominant tick-borne bacteria carried by ticks collected from Wenquan County and

Genome-based taxonomic classification of Listeria phage and diversity analysis of major capsid protein, receptor-binding protein and endolysin

open access: yesFrontiers in Microbiology
IntroductionListeria monocytogenes (Lm) poses a significant risk to food safety due to its adaptability and pathogenicity. In contrast, Listeria phages show great promise as biocontrol agents.MethodThis study comprehensively analyzed 97 complete Listeria

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Parallelized particle filtering for freeway traffic state tracking [PDF]

open access: yes, 2007
We consider parallelized particle filters for state tracking (estimation) of freeway traffic networks. Particle filters can accurately solve the state estimation problem for general nonlinear systems with non-Gaussian noises.
