A Comprehensive and Repeatable Contrast-Enhanced Ultrasound Quantification Approach for Clinical Evaluations of Tumor Blood Flow.

Objective: The aim of this study is to define a comprehensive and repeatable contrast-enhanced ultrasound (CEUS) imaging protocol and analysis method to quantitatively assess lesional blood flow. Easily repeatable CEUS evaluations are essential for longitudinal treatment monitoring. The quantification method described here aims to provide a structure for future clinical studies.

Increased Frequency of Clonal Hematopoiesis of Indeterminate Potential in Bloom Syndrome Probands and Carriers.

Background: Bloom Syndrome (BSyn) is an autosomal recessive disorder caused by biallelic germline variants in which functions to maintain genomic stability. BSyn patients have poor growth, immune defects, insulin resistance, and a significantly increased risk of malignancies, most commonly hematologic. The malignancy risk in carriers of pathogenic variants in ( variant carriers) remains understudied.

Investigating the sources of variable impact of pathogenic variants in monogenic metabolic conditions.

Over three percent of people carry a dominant pathogenic variant, yet only a fraction of carriers develop disease. Disease phenotypes from carriers of variants in the same gene range from mild to severe. Here, we investigate underlying mechanisms for this heterogeneity: variable variant effect sizes, carrier polygenic backgrounds, and modulation of carrier effect by genetic background (marginal epistasis).

mutations in Arboleda-Tham syndrome drive epigenetic regulation of posterior cluster.

Arboleda-Tham Syndrome (ARTHS) is a rare genetic disorder caused by heterozygous, truncating mutations in . ARTHS is clinically heterogeneous and characterized by several common features including intellectual disability, developmental and speech delay, hypotonia and affects multiple organ systems. is highly expressed in early development and plays a key role in cell-type specific differentiation.

Asian American and Pacific Islander patients with melanoma have increased odds of treatment delays: A cross-sectional study.

Background: Asian American and Pacific Islander (AAPI) melanoma patients have higher mortality than non-Hispanic White (NHW) patients. Treatment delays may contribute, but whether AAPI patients have longer time from diagnosis to definitive surgery (TTDS) is unknown.

Objectives: Investigate TTDS differences between AAPI and NHW melanoma patients.

DMRscaler: a scale-aware method to identify regions of differential DNA methylation spanning basepair to multi-megabase features.

Background: Pathogenic mutations in genes that control chromatin function have been implicated in rare genetic syndromes. These chromatin modifiers exhibit extraordinary diversity in the scale of the epigenetic changes they affect, from single basepair modifications by DNMT1 to whole genome structural changes by PRM1/2. Patterns of DNA methylation are related to a diverse set of epigenetic features across this full range of epigenetic scale, making DNA methylation valuable for mapping regions of general epigenetic dysregulation.

Trends of Research Output of Allopathic Medical Students Matching Into Dermatology, 2007-2018.

Importance: According to the National Residency Matching Program's biennial Charting Outcomes in the Match (NRMP ChOM) reports, the mean number of research items of matched allopathic dermatology applicants has nearly tripled since 2007, rising from 5.7 to 14.7.

Identifying Key Genetic Regions for Cell Sheet Morphogenesis on Chromosome 2L Using a Deficiency Screen in Dorsal Closure.

Cell sheet morphogenesis is essential for metazoan development and homeostasis of animal form - it contributes to developmental milestones including gastrulation, neural tube closure, heart and palate formation and to tissue maintenance during wound healing. Dorsal closure, a well-characterized stage in embryogenesis and a model for cell sheet morphogenesis, is a remarkably robust process during which coordination of conserved gene expression patterns and signaling cascades regulate the cellular shape changes and movements. New 'dorsal closure genes' continue to be discovered due to advances in imaging and genetics.

Alzheimer Disease Pathology-Associated Polymorphism in a Complex Variable Number of Tandem Repeat Region Within the MUC6 Gene, Near the AP2A2 Gene.

We found evidence of late-onset Alzheimer disease (LOAD)-associated genetic polymorphism within an exon of Mucin 6 (MUC6) and immediately downstream from another gene: Adaptor Related Protein Complex 2 Subunit Alpha 2 (AP2A2). PCR analyses on genomic DNA samples confirmed that the size of the MUC6 variable number tandem repeat (VNTR) region was highly polymorphic. In a cohort of autopsied subjects with quantitative digital pathology data (n = 119), the size of the polymorphic region was associated with the severity of pTau pathology in neocortex.
