Hemoglobin Rothschild - Unimpaired physical performance and oxygen uptake - A case report with literature review.

Asymptomatic patients with hemoglobin (Hb) variants can be detected by low oxygen levels in pulse oximetry (SpO₂). Depending on the type of Hb variant, low SpO₂ values are either falsely low, with corresponding normal arterial oxygen saturation (SaO₂), or truly low, with low SaO₂ values, as observed in Hb variants with low oxygen binding affinity. In this context, attention must be paid to the method of determining SaO₂.

Tissue-Specific Regulation of the Mouse Epigenome.

The epigenetic landscape varies greatly among cell types. Although a variety of writers, readers, and erasers of epigenetic features are known, we have little information about the underlying regulatory systems controlling the establishment and maintenance of these features. Here, we have explored how natural genetic variation affects the epigenome in mice.

Bottom-up Layer-by-Layer Assembling of Antibacterial Freestanding Nanobiocomposite Films.

In this study, freestanding nanobiocomposite films were obtained by the sequential deposition of biopolymer-capped silver nanoparticles (AgNPs) and hyaluronic acid (HA). At first, dispersions of AgNPs decorated with chitosan (CS) or aminocellulose (AC) were synthesized by applying high intensity ultrasound. These polycationic nanoentities were layer-by-layer assembled with the HA polyanion to generate stable 3D supramolecular constructs, where the biopolymer-capped AgNPs play the dual role of active agent and structural element.

Durable antimicrobial cotton textiles coated sonochemically with ZnO nanoparticles embedded in an in-situ enzymatically generated bioadhesive.

An important preventive measure for providing a bacteria-free environment for the patients is the introduction of highly efficient and durable antibacterial textiles in hospitals. This work describes a single step sono-enzymatic process for coating of cotton medical textiles with antibacterial ZnO nanoparticles (NPs) and gallic acid (GA) to produce biocompatible fabrics with durable antibacterial properties. Cellulose substrates, however, need pre-activation to achieve sufficient stability of the NPs on their surface.

Increased prevalence of depression and anxiety among subjects with metabolic syndrome and known type 2 diabetes mellitus - a population-based study.

Objectives: The metabolic syndrome (MetS) is a cluster of cardiovascular risk factors associated with high cardiovascular morbidity and mortality. The MetS and its elements have been linked to anxiety and depressive disorders. The aim of the current cross-sectional study was to assess the prevalence of depression and anxiety, measured by the Zung Self-Rating Scale in subjects with and without the metabolic syndrome and diabetes.
