Oxidative stress initiates hemodynamic change in CKD-induced heart disease.

Chronic kidney disease (CKD) predisposes to cardiac remodeling and coronary microvascular dysfunction. Studies in swine identified changes in microvascular structure and function, as well as changes in mitochondrial structure and oxidative stress. However, CKD was combined with metabolic derangement, thereby obscuring the contribution of CKD alone.

Aptamer-quantum dots platform for SARS-CoV-2 viral particle detection by fluorescence microscopy.

The virus is the smallest known replicative unit, usually in nanometer-range sizes. The most simple and sensitive detection assay involves molecular amplification of nucleic acids. This work shows a novel, straightforward detection based on the interaction of viral particles with fluorescent nanoconstructs without using enzymatic amplification, washing or separation steps.

New neovagina-creating technique on the basis of a fasciocutaneous flap for Müllerian agenesis.

Objective: To present a new surgical technique on the basis of an internal thigh fasciocutaneous flap for generating a compliant and sensitive neovagina with preservation of the external genitalia.

Design: Video demonstration of the surgical steps.

Patient(s): An 18-year-old woman with Müllerian agenesis confirmed at ultrasound and magnetic resonance imaging.

Deglycosylated RBD produced in Pichia pastoris as a low-cost sera COVID-19 diagnosis tool and a vaccine candidate.

During the COVID-19 outbreak, numerous tools including protein-based vaccines have been developed. The methylotrophic yeast Pichia pastoris (synonymous to Komagataella phaffii) is an eukaryotic cost-effective and scalable system for recombinant protein production, with the advantages of an efficient secretion system and the protein folding assistance of the secretory pathway of eukaryotic cells. In a previous work, we compared the expression of SARS-CoV-2 Spike Receptor Binding Domain in P.

A Plasma Circular RNA Profile Differentiates Subjects with Alzheimer's Disease and Mild Cognitive Impairment from Healthy Controls.

The most frequently used biomarkers to support the diagnosis of Alzheimer’s Disease (AD) are Aβ42, total-Tau, and phospho-tau protein levels in CSF. Moreover, magnetic resonance imaging is used to assess hippocampal atrophy, 18F-FDG PET to identify abnormal brain metabolism, and PET imaging for amyloid deposition. These tests are rather complex and invasive and not easily applicable to clinical practice.
