We study a model of dynamic disorder relevant for signal transduction pathways in which enzymatic reaction rates fluctuate over several orders of magnitude. For the simple networks we consider, dynamic disorder drives the system far from equilibrium and imposes an energetic burden for high fidelity signaling capability. We study how the dynamics of the underlying stochastic behavior in the reaction rate process is related to the energetic cost of transmitting information through the network.

Gastric cancer is an aggressive malignancy characterized by significant clinical heterogeneity arising from complex genetic and environmental interactions. This study employed single-cell RNA sequencing, using the 10 × Genomics platform, to analyze 262,532 cells from gastric cancer samples, identifying 32 distinct clusters and 10 major cell types, including immune cells (e.g.

Parkinson Disease (PD) is a complex neurological disorder attributed by loss of neurons generating dopamine in the SN per compacta. Electroencephalogram (EEG) plays an important role in diagnosing PD as it offers a non-invasive continuous assessment of the disease progression and reflects these complex patterns. This study focuses on the non-linear analysis of resting state EEG signals in PD, with a gender-specific, brain region-specific, and EEG band-specific approach, utilizing recurrence plots (RPs) and machine learning (ML) algorithms for classification.

In complex networks and fluids such as the extracellular matrix, the mechanical properties are substantially affected by the movement of polymers both part of and entrapped in the network. As many cells are sensitive to the mechanical remodeling of their surroundings, it is important to appreciate how entrapped polymers may inhibit or facilitate remodeling in the network. Here, we explore a molecular-level understanding of network remodeling in a complex hydrogel environment through successive compressive loading and the role that noninteracting polymers may play in a dynamic network.

Recombination contributes substantially to the genetic diversity of HIV-1. Here we reported a novel HIV-1 recombinant detected from a Chinese labor who had been to Uganda as an immigrant worker using nanopore sequencing. Near full-length genome (NFLG) phylogenetic analysis showed that the novel HIV-1 recombinant HIV-sd1801 stood in a distinct branch between the CRF130_A1B/CRF131_A1B and CRF50_A1D/CRF84_A1D reference sequences.
