Monocyte uptake of polymeric peptidoglycan is bimodal and governed by complement C3 and C4 opsonins.

Peptidoglycans (PGNs) are structural polymers of the bacterial cell wall and a common microbial molecular pattern encountered by our immune system daily. Low levels of PGNs are constitutively present in the systemic circulation in humans and elevate during inflammatory pathologies. Since all known PGN sensors are intracellular, PGN internalization is a prerequisite for the initiation of cellular immune responses.

Gpx4 Regulates Invariant NKT Cell Homeostasis and Function by Preventing Lipid Peroxidation and Ferroptosis.

Invariant NKT (iNKT) cells are a group of innate-like T cells that plays important roles in immune homeostasis and activation. We found that iNKT cells, compared with CD4+ T cells, have significantly higher levels of lipid peroxidation in both mice and humans. Proteomic analysis also demonstrated that iNKT cells express higher levels of phospholipid hydroperoxidase glutathione peroxidase 4 (Gpx4), a major antioxidant enzyme that reduces lipid peroxidation and prevents ferroptosis.

The association between pupillary responses and axial length in children differs as a function of season.

The association between pupillary responses to repeated stimuli and adult refractive error has been previously demonstrated. This study evaluated whether this association exists in children and if it varies by season. Fifty children aged 8-17 years (average: 11.

Polyamines and hypusination are important for toxin B (TcdB)-mediated activation of group 3 innate lymphocytes (ILC3s).

is the most common cause of nosocomial gastrointestinal tract bacterial infections. We lack fully effective reliable treatments for this pathogen, and there is a critical need to better understand how interacts with our immune system. Group 3 innate lymphocytes (ILC3s) are rare immune cells localized within mucosal tissues that protect against bacterial infections.

Understanding the menopausal experiences of women with intellectual disabilities: A scoping review.

During the process of ageing, women experience important hormonal, endocrine and biological changes. Menopause is a natural phenomenon in female development, during which women's ovarian function shifts from a reproductive to a non-reproductive state. The experience of menopause is unique for every woman, including women with intellectual disabilities.

Death, dying and caring: exploring the student nurse experience of palliative and end-of-life education.

Background: Undergraduate education and training are fundamental in preparing student nurses for working in palliative and end-of-life care.

Aim: This article explores the experiences of student nurses in their palliative and end-of-life undergraduate nurse education.

Methodology: Sandelowski and Barroso's (2007) framework for undertaking a metasynthesis was used.

Nucleotide exchange is sufficient for Hsp90 functions in vivo.

Hsp90 is an essential eukaryotic chaperone that regulates the activity of many client proteins. Current models of Hsp90 function, which include many conformational rearrangements, specify a requirement of ATP hydrolysis. Here we confirm earlier findings that the Hsp82-E33A mutant, which binds ATP but does not hydrolyze it, supports viability of S.

G-CSF Is a Novel Mediator of T-Cell Suppression and an Immunotherapeutic Target for Women with Colon Cancer.

Purpose: G-CSF enhances colon cancer development. This study defines the prevalence and effects of increased G-CSF signaling in human colon cancers and investigates G-CSF inhibition as an immunotherapeutic strategy against metastatic colon cancer.

Experimental Design: Patient samples were used to evaluate G-CSF and G-CSF receptor (G-CSFR) levels by IHC with sera used to measure G-CSF levels.

Human J-Domain Protein DnaJB6 Protects Yeast from [] Prion Toxicity.

Human J-domain protein (JDP) DnaJB6 has a broad and potent activity that prevents formation of amyloid by polypeptides such as polyglutamine, A-beta, and alpha-synuclein, related to Huntington's, Alzheimer's, and Parkinson's diseases, respectively. In yeast, amyloid-based [] prions, which rely on the related JDP Sis1 for replication, have a latent toxicity that is exposed by reducing Sis1 function. Anti-amyloid activity of DnaJB6 is very effective against weak [] prions and the Sup35 amyloid that composes them, but ineffective against strong [] prions composed of structurally different amyloid of the same Sup35.

J Proteins Counteract Amyloid Propagation and Toxicity in Yeast.

The accumulation of misfolded proteins as amyloids is associated with pathology in dozens of debilitating human disorders, including diabetes, Alzheimer's, Parkinson's, and Huntington's diseases. Expressing human amyloid-forming proteins in yeast is toxic, and yeast prions that propagate as infectious amyloid forms of cellular proteins are also harmful. The yeast system, which has been useful for studying amyloids and their toxic effects, has provided much insight into how amyloids affect cells and how cells respond to them.

A review of granulocyte colony-stimulating factor receptor signaling and regulation with implications for cancer.

Granulocyte colony-stimulating factor receptor (GCSFR) is a critical regulator of granulopoiesis. Studies have shown significant upregulation of GCSFR in a variety of cancers and cell types and have recognized GCSFR as a cytokine receptor capable of influencing both myeloid and non-myeloid immune cells, supporting pro-tumoral actions. This systematic review aims to summarize the available literature examining the mechanisms that control GCSFR signaling, regulation, and surface expression with emphasis on how these mechanisms may be dysregulated in cancer.

Perceived end-of-life educational needs by clinical trials nurses at a comprehensive cancer center.

Objective: Determine palliative care end-of-life (EOL) educational needs among clinical trials nurses (CTNs) at an urban comprehensive cancer center.

Methods: The End-Of-Life Professional Caregiver Survey (EPCS) was used to determine the EOL educational needs of CTNs and collect demographics on years of experience, education, past EOL-specific training, and possession of their own advanced directive. The "Surprise Question" was also asked to explore the percent of patients on clinical trials who may be nearing EOL.

Accessory Mitral Valve Tissue and Internal Mammary Artery Stenosis: Unique Considerations After Cardiac Arrest.

A man with recurrent syncope and remote aortic coarctation repair experienced cardiac arrest with exercise stress testing. Critical coronary stenosis was discovered. Further evaluation revealed accessory mitral valve tissue and internal mammary artery occlusion.

Quantifying the potential market for new contraceptive technologies: global projections of 2040 contraceptive needs and preferences.

Despite a wide range of contraceptive methods, unmet need persists. New contraceptive technologies (CTs) have the potential to improve uptake and continuation. CT development has a long-time horizon; products will be introduced into markets that look very different than today.

Association of public explanations of why children struggle and support for policy solutions using a national sample.

Purpose: Despite evidence showing the importance of structural determinants for child well-being and the existence of policies that can promote child well-being, many communities are not adopting these policies. Limited awareness of structural determinants may explain this gap. This study establishes the public's recognition of structural determinants and their associations with support for policies that promote child well-being.

Yeast J-protein Sis1 prevents prion toxicity by moderating depletion of prion protein.

[PSI+] is a prion of Saccharomyces cerevisiae Sup35, an essential ribosome release factor. In [PSI+] cells, most Sup35 is sequestered into insoluble amyloid aggregates. Despite this depletion, [PSI+] prions typically affect viability only modestly, so [PSI+] must balance sequestering Sup35 into prions with keeping enough Sup35 functional for normal growth.

Allele-specific mitochondrial stress induced by Multiple Mitochondrial Dysfunctions Syndrome 1 pathogenic mutations modeled in Caenorhabditis elegans.

Multiple Mitochondrial Dysfunctions Syndrome 1 (MMDS1) is a rare, autosomal recessive disorder caused by mutations in the NFU1 gene. NFU1 is responsible for delivery of iron-sulfur clusters (ISCs) to recipient proteins which require these metallic cofactors for their function. Pathogenic variants of NFU1 lead to dysfunction of its target proteins within mitochondria.

MicroRNA expression profiling and biomarker validation in treatment-naïve and drug resistant non-small cell lung cancer.

Background: In the absence of targetable mutations or immune checkpoints, cisplatin-doublet chemotherapy remains the standard of care in non-small cell lung cancer (NSCLC). Drug resistance has however become a significant clinical challenge. Exploring a role for small non-coding microRNAs (miRNA) as biomarker candidates in cisplatin resistant (CisR) lung cancer is lacking and warrants further investigation.

Single-Dose del Nido Cardioplegia Compared With Standard Cardioplegia During Coronary Artery Bypass Grafting at a Veterans Affairs Hospital.

Del Nido cardioplegic solution (DNC), used chiefly in pediatric patients, rapidly induces prolonged cardiac arrest during cardiac surgery. To determine whether surgical outcomes after coronary artery bypass grafting in a United States military veteran population differed when DNC was used instead of our standard Plegisol cardioplegia, we retrospectively reviewed 155 consecutive operations performed from July 2016 through June 2017. Del Nido cardioplegia was used to induce cardiac arrest in 70 patients, and Plegisol in 85.

Opportunities for psychologists to enact community change through adverse childhood experiences, trauma, and resilience networks.
