Strategic Inhibition of CHRM Autoantibodies: Molecular Insights and Therapeutic Potentials in Long COVID.

In addition to the conventional symptoms reported for COVID-19, it is becoming increasingly clear that patients with long COVID are exhibiting new symptoms due to the emergence of autoantibodies against G-protein-coupled receptors, among which human muscarinic cholinergic receptors (CHRMs) have been prominently reported. With a chronic condition such as long COVID, additional symptoms caused by anti-CHRM autoantibodies (AAbs) have proven to be an added burden on these patients. The origins of these AAbs, their interactions with, and effects on the function of neural and non-neural cells within the nervous system have remained unknown.

To address this need, we developed an innovative mechanism called the "ResearchMatch Expert Advice Tool" that quickly obtains volunteer perspectives from populations with specific health conditions or lived experiences using the national recruitment registry, ResearchMatch.

Long-term, cell type-specific effects of prenatal stress on dorsal striatum and relevant behaviors in mice.

Maternal stress during pregnancy, or prenatal stress, is a risk factor for neurodevelopmental disorders in offspring, including autism spectrum disorder (ASD). In ASD, dorsal striatum displays abnormalities correlating with symptom severity, but there is a gap in knowledge about dorsal striatal cellular and molecular mechanisms that may contribute. Using a mouse model, we investigated how prenatal stress impacted striatal-dependent behavior in adult offspring.

Designing, implementing and evaluating multidisciplinary healthcare training programmes in the wartime humanitarian context of Ukraine.

Introduction: Civilian healthcare workers (HCW) and medical facilities are directly and indirectly impacted by armed conflict. In the Russia-Ukraine war, acute trauma care needs grew, the workforce was destabilised by HCW migrating or shifting roles to meet conflict needs, and facilities faced surge events. Chemical, biological, radiological, nuclear and explosive (CBRNE) exposure risks created unique preparedness needs.

Sex Assignment in Cases of Ambiguous Genitalia.

Ambiguous genitalia is a rare disorder where it is unclear whether an infant's external genitals are male or female. This can be attributed to various internal and external etiologies, such as androgen receptor abnormalities, gonadal abnormalities (such as gonadal dysgenesis or Klinefelter syndrome where a male has an extra X chromosome), enzymatic defects, etc. Correction of such atypical genitalia requires a multidisciplinary approach, including but not limited to surgeons and therapists.

The primary objective of this research is to propose a new feature engineering model that achieves both high classification accuracy and explainable results using ECG signals. To this end, a symbolic language, named Cardioish, has been introduced.

Ultracentrifugation Purification of Cache Valley Virus Using Iodixanol.

Ultracentrifugation is an invaluable technique frequently used for either crude or highly purified viral preparations. Virus produced by cells is first cleared of cellular debris through benchtop centrifugation, then purified by ultracentrifugation in a stepwise iodixanol gradient solution. Here we describe the purification of Cache Valley virus using iodixanol, a nonionic, nontoxic, iso-osmotic solution.

Hybrid Clot Histomic-Transcriptomic Models Predict Functional Outcome After Mechanical Thrombectomy in Acute Ischemic Stroke.

Background And Objectives: Histologic and transcriptomic analyses of retrieved stroke clots have identified features associated with patient outcomes. Previous studies have demonstrated the predictive capacity of histology or expression features in isolation. Few studies, however, have investigated how paired histologic image features and expression patterns from the retrieved clots can improve understanding of clot pathobiology and our ability to predict long-term prognosis.

Host DNA depletion on frozen human respiratory samples enables successful metagenomic sequencing for microbiome studies.

Most respiratory microbiome studies use amplicon sequencing due to high host DNA. Metagenomics sequencing offers finer taxonomic resolution, phage assessment, and functional characterization. We evaluated five host DNA depletion methods on frozen nasal swabs from healthy adults, sputum from people with cystic fibrosis (pwCF), and bronchoalveolar lavage (BAL) from critically ill patients.

Septins as key players in spermatogenesis, fertilisation and pre-implantation embryogenic cytoplasmic dynamics.

Septins are a family of cytokinesis-related proteins involved in regulating cytoskeletal design, cell morphology, and tissue morphogenesis. Apart from cytokinesis, as a fourth component of cytoskeleton, septins aid in forming scaffolds, vesicle sorting and membrane stability. They are also known to be involved in the regulation of intracellular calcium (Ca) via the STIM/Orai complex.

On-the-move heterogeneous face recognition in frequency and spatial domain using sparse representation.

Heterogeneity of a probe image is one of the most complex challenges faced by researchers and implementers of current surveillance systems. This is due to existence of multiple cameras working in different spectral ranges in a single surveillance setup. This paper proposes two different approaches including spatial sparse representations (SSR) and frequency sparse representation (FSR) to recognize on-the-move heterogeneous face images with database of single sample per person (SSPP).
