"Evaluating the Benefits and Limits of Multiple Displacement Amplification with Whole-Genome Oxford Nanopore Sequencing".

Multiple Displacement Amplification (MDA) outperforms conventional PCR in long fragment and whole genome amplification which makes it attractive to couple with long-read sequencing of samples with limited quantities of DNA to obtain improved genome assemblies. Here, we explore the efficacy and limits of MDA for genome sequence assembly using Oxford Nanopore Technologies (ONT) rapid library preparations and minION sequencing. We successfully generated almost complete genome sequences for all organisms examined, including , , , and , with the ability to generate high-quality data from samples starting with only 0.

Achieving a Predictive Understanding of Antimicrobial Stress Physiology through Systems Biology.

The dramatic spread and diversity of antibiotic-resistant pathogens has significantly reduced the efficacy of essentially all antibiotic classes, bringing us ever closer to a postantibiotic era. Exacerbating this issue, our understanding of the multiscale physiological impact of antimicrobial challenge on bacterial pathogens remains incomplete. Concerns over resistance and the need for new antibiotics have motivated the collection of omics measurements to provide systems-level insights into antimicrobial stress responses for nearly 20 years.

A proteomic approach to understanding the pathogenesis of idiopathic macular hole formation.

Idiopathic macular holes (IMH) are full-thickness defects of retinal tissue that cause severe vision loss due to disruption of the anatomic fovea. Abnormal vitreous traction is involved in the formation of macular holes. Both glial cells and hyalocytes contribute to epiretinal membrane formation in IMH.

The proteome of normal human retrobulbar optic nerve and sclera.

The optic nerve is a white matter tract that conveys visual information to the brain. The sclera comprises the white, protective outer layer of the eye. A characterization of the proteome of normal human retrobulbar optic nerve and sclera may facilitate studies of the eye.

Defining the proteome of human iris, ciliary body, retinal pigment epithelium, and choroid.

The iris is a fine structure that controls the amount of light that enters the eye. The ciliary body controls the shape of the lens and produces aqueous humor. The retinal pigment epithelium and choroid (RPE/choroid) are essential in supporting the retina and absorbing light energy that enters the eye.

Changes in oxidized lipids drive the improvement in monocyte activation and vascular disease after statin therapy in HIV.

Background: Oxidative stress plays a significant role in atherosclerosis development. HIV infection has been linked with heightened cardiovascular disease risk. HMG-CoA reductase inhibitors may reduce oxidative stress and subsequently subclinical vascular disease in HIV.

Low Plasma Klotho Concentrations and Decline of Knee Strength in Older Adults.

Background: Although the "anti-aging hormone" klotho is associated with sarcopenia in mice, the relationship between klotho and muscle strength in older adults is not well known.

Methods: Plasma klotho concentrations were measured in 2,734 older adults, aged 71-80 years, who participated in the Health, Aging and Body Composition Study, a prospective observational cohort study conducted in Memphis, TN and Pittsburgh, PA. Knee extension strength was measured using isokinetic dynamometry at baseline and follow-up 2 and 4 years later.

The proteome of human retina.

The retina is a delicate tissue that detects light, converts photochemical energy into neural signals, and transmits the signals to the visual cortex of the brain. A detailed protein inventory of the proteome of the normal human eye may provide a foundation for new investigations into both the physiology of the retina and the pathophysiology of retinal diseases. To provide an inventory, proteins were extracted from five retinas of normal eyes and fractionated using SDS-PAGE.

Dietary intake of advanced glycation end products did not affect endothelial function and inflammation in healthy adults in a randomized controlled trial.

When food is heated to high temperatures, the characteristic "browning" generates advanced glycation end products (AGEs). AGEs are associated with an increased risk of cardiovascular disease, diabetes, and other adverse outcomes. Whether dietary AGEs are absorbed and are harmful to human health remains highly controversial.

Klotho in the cerebrospinal fluid of adults with and without Alzheimer's disease.

The aging-suppressor gene klotho encodes a single-pass transmembrane protein that is predominantly secreted by the choroid plexus of the brain and in the kidney. Klotho-deficient mice develop multiple aging phenotypes, including impaired cognition. Klotho concentrations have not been described in the CSF of humans.
