Perceived problems associated with perioperative blood product preparation.

Timely blood product preparation is important for patients undergoing surgery with a high risk of blood loss. However, in circumstances where no blood refrigerators exist in the operating room theatre complex, numerous potential problem sources during blood product preparation may lead to delays, and tense interpersonal interactions between anaesthesia and blood bank personnel can ensue. To evaluate this at our institution, an anonymous online survey was sent to anaesthesia providers and blood bank technologists.

Dietary cinnamon promotes longevity and extends healthspan via mTORC1 and autophagy signaling.

Cinnamon, renowned for its aromatic flavor, represents one of the most widely used spices worldwide. Cinnamon is also considered beneficial to human health with therapeutic potential for treating various diseases, ranging from diabetes and cancer to neurodegenerative diseases. However, the mechanisms underlying cinnamon's health benefits remain elusive.

Development and Validation of a Brief Warzone Stressor Exposure Index.

Existing scales mainly focus on danger-based threats of death and bodily harm to assess exposure to traumatic events in war zone. However, major provocations and transgression of deeply held values and moral beliefs, as well as witnessing the suffering of others can be as traumatic as fear-inducing danger-based events. This raises the need for scales that assess both danger- and nondanger-based events among soldiers operating in modern war zones.

Distinct chemical structures inhibit the CEMIP hyaluronidase and promote oligodendrocyte progenitor cell maturation.

Growing evidence supports pathogenic roles for chronically elevated hyaluronidase activity in numerous conditions. Elevated expression of one such hyaluronidase, the Cell Migration Inducing and hyaluronan binding Protein (CEMIP), has been implicated in the pathogenesis and progression of several cancers as well as demyelinating diseases in the central nervous system (CNS). Developing effective and selective CEMIP inhibitors could therefore have efficacy in treating a variety of conditions where CEMIP is chronically elevated.

MicroRNA-21 modulates brown adipose tissue adipogenesis and thermogenesis in a mouse model of polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS), the most common endocrine disorder in premenopausal women, is associated with increased obesity, hyperandrogenism, and altered brown adipose tissue (BAT) thermogenesis. MicroRNAs play critical functions in brown adipocyte differentiation and maintenance. We aim to study the role of microRNA-21 (miR-21) in altered energy homeostasis and BAT thermogenesis in a PCOS mouse model of peripubertal androgen exposure.

Empowering standardization of cancer vaccines through ontology: enhanced modeling and data analysis.

Background: The exploration of cancer vaccines has yielded a multitude of studies, resulting in a diverse collection of information. The heterogeneity of cancer vaccine data significantly impedes effective integration and analysis. While CanVaxKB serves as a pioneering database for over 670 manually annotated cancer vaccines, it is important to distinguish that a database, on its own, does not offer the structured relationships and standardized definitions found in an ontology.

Ontological representation, modeling, and analysis of parasite vaccines.

Background: Pathogenic parasites are responsible for multiple diseases, such as malaria and Chagas disease, in humans and livestock. Traditionally, pathogenic parasites have been largely an evasive topic for vaccine design, with most successful vaccines only emerging recently. To aid vaccine design, the VIOLIN vaccine knowledgebase has collected vaccines from all sources to serve as a comprehensive vaccine knowledgebase.

COMPARISON OF SUBCUTANEOUS ALFAXALONE AND SUBCUTANEOUS ALFAXALONE-DEXMEDETOMIDINE FOR SEDATION IN THE HOUSTON TOAD ().

The Houston toad (), a primarily terrestrial amphibian of south-central Texas, has been listed as federally endangered since 1970. Sedation is an important tool for obtaining diagnostics and providing treatment in this species. This prospective, randomized, and blinded study compared the sedative effects of SC alfaxalone (Protocol A) at approximately 12 mg/kg (median [range] = 12.

CanVaxKB: a web-based cancer vaccine knowledgebase.

Cancer vaccines have been increasingly studied and developed to prevent or treat various types of cancers. To systematically survey and analyze different reported cancer vaccines, we developed CanVaxKB (https://violinet.org/canvaxkb), the first web-based cancer vaccine knowledgebase that compiles over 670 therapeutic or preventive cancer vaccines that have been experimentally verified to be effective at various stages.

Boundary-bound reactions: Pattern formation with and without hydrodynamics.

We study chemical pattern formation in a fluid between two flat plates and the effect of such patterns on the formation of convective cells. This patterning is made possible by assuming the plates are chemically reactive or release reagents into the fluid, both of which we model as chemical fluxes. We consider this as a specific example of boundary-bound reactions.

Vaxign-DL: A Deep Learning-based Method for Vaccine Design and its Evaluation.

Reverse vaccinology (RV) provides a systematic approach to identifying potential vaccine candidates based on protein sequences. The integration of machine learning (ML) into this process has greatly enhanced our ability to predict viable vaccine candidates from these sequences. We have previously developed a Vaxign-ML program based on the eXtreme Gradient Boosting (XGBoost).

Differences in resilience profiles between military veterans and the general population: An exploratory latent profile analysis using the HUNT-4 survey.

Using latent profile analyses, the current work investigated levels of adverse childhood experiences, symptoms of anxiety and depression and 3 dimensions of relational promotive factors) to identify resilience profiles in a large general population sample (N = 161,622, mean age = 53.02; SD = 17.80; 56.

Biomarkers in Polycystic Ovary Syndrome.

Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder in reproductive-age women. PCOS is diagnosed by the presence of two of the following three characteristics: hyperandrogenemia and/or hyperandrogenism, oligo/amenorrhea, and polycystic ovarian morphology. PCOS is associated with reproductive and non-reproductive complications, including obesity, insulin resistance and diabetes, dyslipidemia, and increased blood pressure.

Ontology-based representation and analysis of conditional vaccine immune responses using Omics data.

ImmPort, the world's largest repository of immunology data, includes many vaccine immune response datasets. ImmPort maps the metadata of these studies to ontology and database schema. As of February 28, 2023, our ImmPort data analysis identified 6.

VIGET: A web portal for study of vaccine-induced host responses based on Reactome pathways and ImmPort data.

Host responses to vaccines are complex but important to investigate. To facilitate the study, we have developed a tool called Vaccine Induced Gene Expression Analysis Tool (VIGET), with the aim to provide an interactive online tool for users to efficiently and robustly analyze the host immune response gene expression data collected in the ImmPort/GEO databases. VIGET allows users to select vaccines, choose ImmPort studies, set up analysis models by choosing confounding variables and two groups of samples having different vaccination times, and then perform differential expression analysis to select genes for pathway enrichment analysis and functional interaction network construction using the Reactome's web services.

Loss of microRNA-21 protects against acetaminophen-induced hepatotoxicity in mice.

Acetaminophen (APAP)-induced Acute Liver Failure (ALF) is recognized as the most common cause of ALF in Western societies. APAP-induced ALF is characterized by coagulopathy, hepatic encephalopathy, multi-organ failure, and death. MicroRNAs are small, non-coding RNAs that regulate gene expression at the post-transcriptional level.

Supportive Care Needs Among Head and Neck Cancer Patients Prior to Oncologic Treatment: A Prospective, Nested Cross-Sectional Qualitative Analysis.

Objectives: To qualitatively characterize pretreatment head and neck cancer (HNC) patients' supportive care (SC) needs, attitudes toward SC, and barriers to SC utilization.

Materials And Methods: A prospective, nested, bi-institutional, cross-sectional pilot study design was employed. Participants were sub-selected from a representative sample of 50 patients newly diagnosed with mucosal or salivary gland HNC or sarcoma of the head and neck.

A Randomized Clinical Trial Testing Hydroxychloroquine for Reduction of SARS-CoV-2 Viral Shedding and Hospitalization in Early Outpatient COVID-19 Infection.

Early in the COVID-19 pandemic, no effective treatment existed to prevent clinical worsening of COVID-19 among recently diagnosed outpatients. At the University of Utah, Salt Lake City, Utah, we conducted a phase 2 prospective parallel group randomized placebo-controlled trial (NCT04342169) to determine whether hydroxychloroquine given early in disease reduces the duration of SARS-CoV-2 shedding. We enrolled nonhospitalized adults (≥18 years of age) with a recent positive diagnostic test for SARS-CoV-2 (within 72 h of enrollment) and adult household contacts.

Physical clinical care and artificial-intelligence-guided core resistance training improve endurance and patient-reported outcomes in subjects with lower back pain.

Background: Low back pain is an extremely prevalent issue with an extensive impact, ranging from decreased quality of life to lost years of productivity. Many interventions have been developed to alleviate chronic lower back pain, yet it remains a widespread problem. The objective of this study was to examine the role of artificial intelligence guided resistance training relative to clinical variables in subjects experiencing lower back pain.

A new framework for host-pathogen interaction research.

COVID-19 often manifests with different outcomes in different patients, highlighting the complexity of the host-pathogen interactions involved in manifestations of the disease at the molecular and cellular levels. In this paper, we propose a set of postulates and a framework for systematically understanding complex molecular host-pathogen interaction networks. Specifically, we first propose four host-pathogen interaction (HPI) postulates as the basis for understanding molecular and cellular host-pathogen interactions and their relations to disease outcomes.

A comprehensive update on CIDO: the community-based coronavirus infectious disease ontology.

Background: The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis.

Mitochondrial function and oxidative stress in white adipose tissue in a rat model of PCOS: effect of SGLT2 inhibition.

Background: Polycystic ovary syndrome (PCOS), characterized by androgen excess and ovulatory dysfunction, is associated with a high prevalence of obesity and insulin resistance (IR) in women. We demonstrated that sodium-glucose cotransporter-2 inhibitor (SGLT2i) administration decreases fat mass without affecting IR in the PCOS model. In male models of IR, administration of SGLT2i decreases oxidative stress and improves mitochondrial function in white adipose tissue (WAT).
