The Flipped Classroom Approach in a Pediatric Anesthesiology Fellowship Curriculum.

Background The flipped classroom approach is well documented to enhance medical education outcomes. Additionally, both the need for online learning materials and the increased demand for medical professionals during the COVID-19 pandemic has made this approach more relevant. The pediatric anesthesiology fellowship curriculum at one institution transitioned from a traditional classroom model to a flipped classroom approach to optimize the educational experience and support learner well-being.

Identification of Tumor Antigens in Ovarian Cancers Using Local and Circulating Tumor-Specific Antibodies.

Ovarian cancers include several disease subtypes and patients often present with advanced metastatic disease and a poor prognosis. New biomarkers for early diagnosis and targeted therapy are, therefore, urgently required. This study uses antibodies produced locally in tumor-draining lymph nodes (ASC probes) of individual ovarian cancer patients to screen two separate protein microarray platforms and identify cognate tumor antigens.

Immunoprofiling of Breast Cancer Antigens Using Antibodies Derived from Local Lymph Nodes.

Tumor antigens are responsible for initiating an immune response in cancer patients, and their identification may provide new biomarkers for cancer diagnosis and targets for immunotherapy. The general use of serum antibodies to identify tumor antigens has several drawbacks, including dilution, complex formation, and background reactivity. In this study, antibodies were generated from antibody-secreting cells (ASC) present in tumor-draining lymph nodes of 20 breast cancer patients (ASC-probes) and were used to screen breast cancer cell lines and protein microarrays.

Revisiting the applicability of adult early post-operative nausea and vomiting risk factors for the paediatric patient: A prospective study using cotinine levels in children undergoing adenotonsillectomies.

Background And Aims: Post-operative vomiting (POV) in children remains a significant clinical problem. This prospective study aims to investigate the applicability of well-established adult early post-operative nausea and vomiting (PONV) risk factors on paediatric POV after adenotonsillectomies under regulated anaesthetic conditions.

Methods: After Institutional Review Board approval, 213 children aged 3-10-year-old were enrolled.

Galectin secretion and binding to adult Fasciola hepatica during chronic liver fluke infection of sheep.

Galectins are increasingly recognised as important mediators of immune homeostasis and disease regulation, but comparatively little is known about their role in parasite infection. This study investigates the interaction between two ovine galectins, galectin-11 and galectin-14, and the parasitic liver fluke, F. hepatica.

Functional characterization of an eosinophil-specific galectin, ovine galectin-14.

Across mammalian species, human galectin-10 and ovine galectin-14 are unique in their expression in eosinophils and their release into lung and gastrointestinal tissues following allergen or parasite challenge. Recombinant galectin-14 is active in carbohydrate binding assays and has been used in this study to unravel the function of this major eosinophil constituent. In vitro cultures revealed that galectin-14 is spontaneously released by eosinophils isolated from allergen-stimulated mammary gland lavage, but not by resting peripheral blood eosinophils.

Production of monoclonal antibodies reactive with ovine eosinophils.

Background: There is strong evidence implicating eosinophils in host defence against parasites as well as allergic disease pathologies. However, a lack of reagents such as monoclonal antibodies (mAbs) specific for eosinophils has made it difficult to confirm the functional role of eosinophils in such disease conditions. Using an established mammary model of allergic inflammation in sheep, large numbers of inflammatory cells enriched for eosinophils were collected from parasite-stimulated mammary glands and used for the generation of mAbs against ovine eosinophils.

Galectins in parasite infection and allergic inflammation.

Galectins are increasingly recognised as important immunological mediators of homeostasis and disease regulation. This paper gives an overview of current knowledge of galectin involvement in parasite infection and allergic inflammation, two very different but immunologically linked phenomena. Galectins are produced by both the parasite and the host and appear to be intimately involved in parasite establishment, as well as directing the course of infection and the immune response.

Isolation and characterization of a novel eosinophil-specific galectin released into the lungs in response to allergen challenge.

A novel galectin cDNA (galectin-14) was cloned from ovine eosinophil-rich leukocytes by low stringency reverse transcriptase-PCR and cDNA library screening. Data base searches indicate that this gene encodes a novel prototype galectin that contains one putative carbohydrate recognition domain and exhibits most identity to galectin-9/ecalectin, a potent eosinophil chemoattractant. The sugar binding properties of the recombinant molecule were confirmed by a hemagglutination assay and lactose inhibition.
