Influence of millimeter range electromagnetic waves on bovine serum albumin interaction with acridine orange.

The effect of non-ionizing millimeter range electromagnetic waves (MM EMW) (30-300 GHz) on the bovine serum albumin (BSA) interaction peculiarities with acridine orange (AO) has been studied in vitro. The frequencies 41.8 and 50.

Patient outcome scores between 1,2- and 2,3-intercompartmental supra-retinacular artery (ICSRA) pedicled vascularised bone grafts (PVBGs) in the treatment of proximal pole scaphoid fracture non-union - a questionnaire study.

Background: Numerous studies have been published on the use of 1,2-intercompartmental supra-retinacular artery (ICSRA) as a pedicled vascularised bone graft (PVBG) in scaphoid fracture non-union, however, only very few studies have reported their results of 2,3-ICSRA. The aim of this study was to compare the patient-rated outcome scores between these two PVBGs in proximal pole scaphoid fracture non-union.

Methods: Nineteen patients who underwent surgery for scaphoid non-union between 2017 and 2021 at a single institution were recruited retrospectively in this study.

Detection of Saccharomyces cerevisiae by silver nanoparticles sensitized with various lectins.

Anisotropic silver nanoparticles sensitized by various lectins were applied for detection of yeast (Saccharomyces cerevisiae) which was used as a model of fungal cells. It was shown that high concentrations of yeast cells have stabilized silver nanoparticles, preventing their aggregation in the presence of NaCl whereas at low concentrations of cells, the salt has induced aggregation of nanoparticles with drastic changes in optical spectra. These changes depend on cell concentration and permit the detection of cells in the range from 3.

Antibodies to oxidized lipoproteins in human normal plasma, detection and analysis.

In the article, presence of antibodies to protein components of oxidized human donor plasma was demonstrated. It was shown that normal plasma oxidized by CuCl, FeSO, or potassium ferricyanide acquired ability to bind with human IgG-sensitized polystyrene latex particles and colloidal gold nanoparticles. Ability of these antibodies to bind to oxidized components strongly depends on time of oxidation.

Acute and chronic brucellosis eleven-year audit from a tertiary hospital in Armenia.

Introduction: The incidence of brucellosis in Armenia in 2010 was twice as high as in other countries of the Caucasian region and has almost doubled over the last three decades. This study aimed to investigate factors associated with acute or chronic forms of presentation of human brucellosis.

Methodology: Retrospective study using data from medical records of 455 patients hospitalized for the first time at the Nork Republican Infectious Disease Referral Hospital in Yerevan, Armenia between the years 2006 and 2016.
