Single Cell Transcriptomic Analysis of Pancreatic β Cell Development and Differentiation from Pluripotent Stem Cells

Received: 06 May 2019;  Published: 17 July 2019;  doi: 10.21926/obm.transplant.1903072

Abstract

Single cell genomics is a powerful tool to study cellular heterogeneity and discover novel cell types. Recent studies used single cell RNA sequencing (scRNA-seq) to analyze the transcriptomes of individual pancreatic islet cells. Islets are a complex mixture of endocrine cells and therefore represent an ideal tissue type for single cell transcriptomic analysis. Adult human islets consist of five known endocrine cell types (α, β, δ, γ, ε) and multiple less well-defined non-endocrine cells. In this review, we discuss [...]

Role of Procalcitonin in Management of Infection in Solid Organ Transplantation Recipients: Review

Received: 23 December 2018;  Published: 01 March 2019;  doi: 10.21926/obm.transplant.1901054

Abstract

Infections are a common cause of morbidity and mortality in solid organ transplantation (SOT) recipients. Procalcitonin (PCT) has garnered attention as an inflammatory marker that has been shown to be a valuable marker for early identification of systemic bacterial infection. However, interpretation of PCTs value in the different types of infections, transplanted organs, and post-operative courses can be challenging. We review the role of PCT in the management of infections in SOT recipients. First, the PCT level c [...]

Live-Born Double Aneuploidy at the Johns Hopkins Cytogenomics Laboratory: Case Report and Review of the Literature

Received: 30 June 2022;  Published: 07 November 2022;  doi: 10.21926/obm.genet.2204168

Abstract

Double aneuploidy is the co-occurrence of aneuploidy of two different chromosomes within the same individual. Genomic imbalance associated with two aneuploidies in humans is associated with early lethality, and observation in live-born humans is rare. In isolation, trisomy of chromosomes 13, 18, 21, X, and Y may be better tolerated, whereas monosomy of X is the only such type of aberration that may be compatible with life. It is hypothesized that two successive malsegregation events must occur in early development [...]

Examining the Social Signaling and Person Perception Functions of Loneliness

Received: 07 January 2022;  Published: 19 April 2022;  doi: 10.21926/obm.neurobiol.2202119

Abstract

Loneliness is a common condition that poses substantial risks to morbidity and mortality. Cacioppo and Cacioppo’s [1] evolutionary theory of loneliness (ETL) provides that loneliness serves a social signaling function and also manifests in hypervigilance to threat, which we propose can influence person perception. In this experiment, 480 observers evaluated videotaped self-presentation messages from speakers who scored either high or low on a measure of loneliness. On the basis of ETL, we hypothesized that observer [...]
