Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by the loss of insulin-producing cells in the pancreatic islets. Patients with T1D have autoreactive CD4 and CD8 T cells that show specific features, indicating previous exposure to self-antigens. Despite that memory T cells are vital components of the adaptive immune system, providing enduring protection against pathogens; individuals with T1D have a higher proportion of memory T cells compared to healthy individuals with naїve phenotypes.

The blood-brain barrier (BBB) is a specialized network that maintains central nervous system homeostasis. Disruption of the BBB can lead to neuronal damage and contribute to neurodegenerative diseases like Parkinson's disease (PD), characterized by alpha-synuclein (αSN) aggregation, which forms intracellular inclusions. Mesenchymal stem cells (MSCs) have shown promise in alleviating the severity of neurological diseases through their paracrine secretions.

Many machine learning techniques have been used to construct gene regulatory networks (GRNs) through precision matrix that considers conditional independence among genes, and finally produces sparse version of GRNs. This construction can be improved using the auxiliary information like gene expression profile of the related species or gene markers. To reach out this goal, we apply a generalized linear model (GLM) in first step and later a penalized maximum likelihood to construct the gene regulatory network using Glasso technique for the residuals of a multi-level multivariate GLM among the gene expressions of one species as a multi-levels response variable and the gene expression of related species as a multivariate covariates.

Langmuir

January 2025

Prof. Rashidi Laboratory of Organometallic Chemistry & Material Chemistry, Department of Chemistry, College of Science, Shiraz University, Shiraz, 7194684795, Iran.

In this study, a Pd nanoparticles@hydrogen-bonded organic framework (Pd NPs@HOF) thin film was fabricated at the toluene-water interface. The HOF was formed through the interaction of trimesic acid (TMA) and melamine (Mel) in the water phase, while Pd(0) was produced from the reduction of [PdCl(cod)] in the organic phase. The as-synthesized Pd NPs@HOF thin film was demonstrated to be an effective catalyst for the selective reduction of -nitrophenol and -nitrophenol to -aminophenol and -aminophenol.
