Monozygotic twins with familial hypercholesterolemia and high lipoprotein(a) levels leading to identical cardiovascular outcomes: Case report and review of the literature.

Turk Kardiyol Dern Ars 2020 Jul;48(5):531-538

Department of Cardiology, Hacettepe University Faculty of Medicine, Ankara, Turkey.

Homozygous familial hypercholesterolemia (HoFH) is a rare, autosomal dominant disease that leads to premature cardiovascular disease (CVD). Since monozygotic twins share the intrauterine environment and have the same age and gene profile, they could represent a very special resource for the investigation of the causes and the natural course of FH. This report is a description of 36-year-old monozygotic twin brothers with almost identical early coronary artery involvement due to FH concomitant with high lipoprotein(a) (Lpa) levels and a review of the literature.

Complementary role of different imaging modalities in the diagnosis of concurrent obstructive aortic and mitral prosthetic valve thrombosis.

Turk Kardiyol Dern Ars 2020 Jul;48(5):539-544

Department of Cardiology, Kartal Koşuyolu High Speciality Training and Research Hospital, İstanbul, Turkey.

Prosthetic valve thrombosis (PVT) is a life-threatening valve dysfunction. In asymptomatic cases, as well as certain symptomatic patients with PVT, the results of the first-line imaging tool, transthoracic echocardiography, may be inconclusive in terms of illustrating the thrombus, which is necessary in order to select the proper treatment option. Hence, a differential diagnosis based on clinical presentation may be challenging, and multimodality imaging, including echocardiography, cine fluoroscopy, and cardiac computed tomography, is usually required to distinguish between PVT and other prosthesis-related pathologies, such as pannus, vegetation, and prosthesis-patient mismatch.

Improvement in estimation of time since death by albumin and potassium concentrations in vitreous humor.

Forensic Sci Int 2020 Jun 27;314:110393. Epub 2020 Jun 27.

Section of Forensic Medical Sciences, Department of Health Sciences, University of Florence, Florence, Italy.

The measurement of the potassium concentration (K) in vitreous humor (VH) has been a well-known adjunct for the estimation of the post-mortem interval (PMI) since the early 1960s. For years, however, many authors have been using other biochemical markers in an attempt to improve predictions.

Identification of genetic loci associated with forage quality in response to water deficit in autotetraploid alfalfa (Medicago sativa L.).

BMC Plant Biol 2020 Jul 1;20(1):303. Epub 2020 Jul 1.

United States Department of Agriculture-Agricultural Research Service, Plant Germplasm Introduction and Testing Research, 24106 N Bunn Road, Prosser, WA, 99350, USA.

Background: Alfalfa has been cultivated in many regions around the world as an important forage crop due to its nutritive value to livestock and ability to adapt to various environments. However, the genetic basis by which plasticity of quality-relevant traits influence alfalfa adaption to different water conditions remain largely unknown.

Results: In the present study, 198 accessions of alfalfa of the core collection for drought tolerance were evaluated for 26 forage quality traits in a field trial under an imposed deficit irrigation gradient. Read More

RNA aptamer capture of macromolecular complexes for mass spectrometry analysis.

Nucleic Acids Res 2020 Jul 1. Epub 2020 Jul 1.

Department of Molecular Biology and Genetics, Cornell University, Ithaca, NY, USA.

Specific genomic functions are dictated by macromolecular complexes (MCs) containing multiple proteins. Affinity purification of these complexes, often using antibodies, followed by mass spectrometry (MS) has revolutionized our ability to identify the composition of MCs. However, conventional immunoprecipitations suffer from contaminating antibody/serum-derived peptides that limit the sensitivity of detection for low-abundant interacting partners using MS. Read More

Using Pixel-Based Microscope Images to Generate 3D Reconstructions of Frozen and Thawed Plant Tissue.

Methods Mol Biol 2020 ;2156:119-139

USDA-ARS and North Carolina State University, Raleigh, NC, USA.

Histological analysis of frozen and thawed plants has been conducted for many years but the observation of individual sections only provides a two-dimensional representation of a three-dimensional phenomenon. Currently available optical sectioning techniques for viewing internal structures in three dimensions are either low in resolution or the instrument cannot penetrate deep enough into the tissue to visualize the whole plant. Methods using higher resolution equipment are expensive and often require time-consuming training. Read More

Identification of cell type-specific methylation signals in bulk whole genome bisulfite sequencing data.

Genome Biol 2020 Jul 1;21(1):156. Epub 2020 Jul 1.

Department of Pediatrics, Baylor College of Medicine, USDA/ARS Children's Nutrition Research Center, Houston, TX, USA.

Background: The traditional approach to studying the epigenetic mechanism CpG methylation in tissue samples is to identify regions of concordant differential methylation spanning multiple CpG sites (differentially methylated regions). Variation limited to single or small numbers of CpGs has been assumed to reflect stochastic processes. To test this, we developed software, Cluster-Based analysis of CpG methylation (CluBCpG), and explored variation in read-level CpG methylation patterns in whole genome bisulfite sequencing data.
