Article Abstract
The present study aimed to uncover the underlying mechanisms and potential intervention targets of ischemic stroke (IS). An immune cell infiltration analysis using CIBERSORT was performed on two stroke-related datasets from the Gene Expression Omnibus database to generate a competitive endogenous RNA (ceRNA) network. Gene Ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were used to predict potential biological functions of the network. Differentially expressed genes in the ceRNA network and programmed cell death-related genes were intersected to obtain common genes for a stroke ceRNA network related to programmed cell death. These genes were further verified through a middle cerebral artery occlusion rat model using reverse transcription-quantitative PCR. This built a ceRNA regulatory network based on bioinformatic analysis. In addition to the biological functions extracted from the GO and KEGG enrichment analyses, it was discovered that long non-coding (lnc)RNA-mediated ceRNA regulatory pathways were associated with programmed cell death. This included five for apoptosis (lncRNA deleted in lymphocytic leukemia 2 like (DLEU2L)/micro (miR)-4500/sulfite oxidase, lncRNA DLEU2L/miR-4500/transforming growth factor β receptor III, lncRNA DLEU2L/miR-4500/BTB and CNC homology 1 (BACH1), lncRNA DLEU2L/miR-4500/zinc finger and BTB domain containing 5 and lncRNA LINC00266-1/miR-363-3p/zinc finger protein 354B and two for ferroptosis (lncRNA DLEU2L/miR-4500/ribo-nucleotide reductase regulatory subunit M2 and lncRNA DLEU2L/miR-4500/BACH1). Based on the aforementioned results, the present study provided potential approaches for bridging programmed cell death, immune infiltration and ceRNA regulatory networks in IS. The present study may provide novel insights into the clinical diagnosis and treatment of IS, and may improve the knowledge of the regulation of pathophysiological processes for IS.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.

Objective: To estimate the prevalence of various hemoglobinopathies among newborns, women in antenatal clinic and children presenting with signs and symptoms suggestive of sickle cell disease (SCD).
Methods: A hospital-based prospective study was conducted at a Centre of Excellence for SCD (COESCD). Dried blood spot (DBS) samples were collected for newborn screening using heel-prick and venous samples were used in the post-neonatal age group.

Highly pathogenic avian influenza (HPAI) H5N1 virus poses a continuing global public health threat due to its outbreaks in poultry farms and zoonotic transmission from birds to humans. In the quest of effective therapeutics against H5N1 infection, antibodies with broad neutralizing activity have attracted significant attention. In this study, we employed a phage display technique to select and identify VHH antibodies with specific neutralizing activity against H5N1 hemagglutinin (HA) from an immune llama-derived antibody library.

This case report describes the use of doxazosin (Cardura) as a treatment for a patient with an autosomal dominant , single-nucleotide R398Q pathogenic variant, which has not previously been described in the literature. The patient has gain-of-function pathogenic genetic variant. Because of the patient's continued seizure burden with the use of traditional antiseizure medications and failed invasive antiseizure interventions, an oocyte cell line with the specific genetic variant was created to test efficacy of various medications.

DNA polymerase theta (Polθ) plays a critical role in repairing DNA double-strand breaks through microhomology-mediated end joining (MMEJ) and has emerged as a key synthetic lethal drug target in cancers with homologous recombination (HR) deficiencies. Its inhibition has shown a strong potential to synergize with PARP inhibitors, particularly in tumors with deleterious or mutations. Here, we describe the discovery and preclinical development of RP-2119, a selective, potent, and bioavailable Polθ ATPase inhibitor.
