Vegetative and reproductive characters of Meridionella gen. nov. are described, and implications of our results for the biogeography of the family Cystocloniaceae are discussed.

11β-Hydroxysteroid dehydrogenase 1 (11β-HSD1) regulates tissue-specific glucocorticoid metabolism and its impaired expression and activity are associated with major diseases. Pharmacological inhibition of 11β-HSD1 is considered a promising therapeutic strategy. This study investigated whether alternative 7-oxo bile acid substrates of 11β-HSD1 or the ratios to their 7-hydroxy products can serve as biomarkers for decreased enzymatic activity.

Bile acid profiles were measured by ultra-HPLC tandem-MS in plasma and liver tissue samples of four different mouse models with decreased 11β-HSD1 activity global (11KO) and liver-specific 11β-HSD1 knockout mice (11LKO), mice lacking hexose-6-phosphate dehydrogenase (H6pdKO) that provides cofactor NADPH for 11β-HSD1 and mice treated with the pharmacological inhibitor carbenoxolone. Additionally, 11β-HSD1 expression and activity were assessed in H6pdKO- and carbenoxolone-treated mice.

The enzyme product to substrate ratios were more reliable markers of 11β-HSD1 activixysterols, Lifelong Health and Therapeutics. To view the other articles in this section visit http//onlinelibrary.wiley.com/doi/10.1111/bph.v178.16/issuetoc.

Cross-reactive hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) is a relatively common adverse drug event caused by two or more chemically unrelated drugs and that is attributed to inhibition of the COX activity, particularly COX-1. JAK inhibitor Several studies investigated variations in the genes coding for COX enzymes as potential risk factors. However, these studies only interrogated a few single nucleotide variations (SNVs), leaving untested most of the gene sequence.

In this study, we analysed the whole sequence of the prostaglandin-endoperoxide synthase genes, PTGS1 and PTGS2, including all exons, exon-intron boundaries and both the 5' and 3' flanking regions in patients with cross-reactive hypersensitivity to NSAIDs and healthy controls. After sequencing analysis in 100 case-control pairs, we replicated the findings in 540 case-control pairs. Also, we analysed copy number variations for both PTGS genes.

The most salient finding was the presence of two PTGS1 single nucleotide variations, which are significantly more frequent in patients than in control subjects. Patients carrying these single nucleotide variations displayed a significantly and markedly lower COX-1 activity as compared to non-carriers for both heterozygous and homozygous patients.

Although the risk single nucleotide variations are present in a small proportion of patients, the strong association observed and the functional effect of these single nucleotide variations raise the hypothesis of genetic susceptibility to develop cross-reactive NSAID hypersensitivity in individuals with an impairment in COX-1 enzyme activity.

The detection of these differences will enable the development of sex-discriminating molecular markers, which are useful for algae showing little apparent difference between sexes. In this study, we identified male- and female-specific DNA sequences in the ulvophycean marine green alga Monostroma angicava, which has a dioicous heteromorphic haplo-diplontic life cycle, via next-generation sequencing. Fluorescence in situ hybridization (FISH) showed that signals for the sex-specific sequences exist only in the nuclei of the corresponding sex, confirming the specificity of the sequences. Sex-specific molecular markers that targeted these sequences successfully distinguished the sex of gametophytes even in geographically distant populations, indicating that the sex-specific sequences are universal. These results consistently suggest that male and female gametophytes of M. angicava are genetically different, implying that sex may be determined genetically in this alga.We describe the case of a child with progressive abdominal pain and rash admitted to a large tertiary children's hospital in the Chicago metropolitan area and subsequently found to have immunoglobulin A (IgA) vasculitis and coronavirus disease 2019 (COVID-19). This patient presented with abdominal pain, purpuric lesions, hematochezia, increasingly elevated D-dimer, and abnormal inflammatory markers on laboratory evaluation. To the best of our knowledge, this article describes the only reported pediatric case of COVID-19 associated with IgA vasculitis.

This type of education and approach has been favored over traditional educational methods and may also improve caregivers' comfort, confidence, knowledge, skills, and ability to manage their child's routine and emergent care at home. Pediatricians play a vital role in this type of education as an advocate for their patients and families and as key stakeholders and collaborators in the process. Open collaboration and information sharing among home caregivers, simulation experts, pediatricians, and the rest of the medical team can lead to the development and implementation of successful simulation curricula. This in turn has the potential to lead to improved patient safety, quality of care, and patient outcomes. [Pediatr Ann. 2021;50(1)e39-e43.].Patient- and family-centered care focuses on relationships among patients, families, and health care providers that are mutually beneficial and improve health care outcomes and provider satisfaction. Building relationships is a key component of the provision of excellent health care and can be taught and enhanced through simulation-based communication skills training. This article reviews the available literature on simulation-based learning as used to improve patient- and family- centered communication in the discipline of pediatrics. In this narrative review, we examine the various methods, theories, and frameworks on which simulation-based learning for communication skills are built with the goal of assisting pediatric providers in using this powerful educational technique.
