Virtual reality exposure therapy to decrease anxiety before surgical invasive procedures in hemodialysis patients: an interventional study.

Background: Hemodialysis patients are prone to anxiety and depression due to physiological changes and psychological tensions that leave irreversible effects on the patients. In this regard, the present study was an attempt to provide a simulated situation by using virtual reality on the anxiety level of dialysis patients before performing surgical procedures.

Methods: This non-equivalent groups pre-posttest quasi-experimental study was conducted in 2022 in a hemodialysis ward of Imam Khomeini General Hospital affiliated with Tehran University of Medical Sciences.

Investigation of correlation between H63D and C282Y mutations in HFE gene and serum Ferritin level in beta-thalassemia major patients.

Introduction: Mutations in the HFE gene have been shown to be associated with hemochromatosis which is observed in beta-thalassemia major. In this study, we determined the HFE gene mutations (C282Y and H63D) among b-thalassemia major patients to investigate the effect of these mutations on serum Ferritin levels.

Material And Methods: In this cross-sectional study, a total of 105 b-thalassemia subjects with a history of regular blood transfusion were selected.

Novel Point Mutations in and Genes Associated with Itraconazole and Posaconazole Resistance in Isolates.

is a common environmental species known to cause occupational allergic disease in grain handlers. We have recently observed azole-resistant isolates of this fungus as a cause of onychomycosis. To further characterize the cause of resistance, the genes encoding 14 α-sterol demethylase enzyme ( and ) were characterized and analyzed in 9 ITC-susceptible isolates and 6 isolates with high minimum inhibitory concentrations (MICs) of clinical (nail and sputum) and environmental strains.

Low Antifungal Activity of Tavaborole against Yeasts and Molds from Onychomycosis.

The activity of tavaborole, an FDA-approved antifungal drug, was compared to that of four antifungal agents against 170 clinical fungal isolates originating from patients with onychomycosis. Tavaborole had low activity against all isolates compared to itraconazole, terbinafine, and fluconazole, the principal choices for treatment of onychomycosis. Thus, it appears that tavaborole is not a candidate for the treatment of onychomycosis due to species, species, and dermatophytes.

Scrap tyre pyrolysis: Modified chemical percolation devolatilization (M-CPD) to describe the influence of pyrolysis conditions on product yields.

This paper attempts to develop a modified chemical percolation devolatilization (M-CPD) model that can include heat transfer, primary pyrolysis and the secondary cracking reactions of volatiles together to describe the pyrolysis of waste scrap tyre chip, as well as to examine the influence of operating conditions on the scrap tyre pyrolysis product yields. Such a study has yet to be conducted in the past, thereby leading to a large knowledge gap failing to understand the pyrolysis of the coarse feedstock appropriately. To validate the developed model, a number of operating parameters including reactor configurations, carrier gas compositions (argon and argon blended with CO and/or steam), scrap tyre chip size (0.

Factors affecting the transfer of radionuclides from the environment to plants.

Much of our food directly or indirectly originates from plant material; thus, detailed studies on plant contamination processes are an essential part of international environmental research. This overview attempts to identify and describe the most important parameters and processes affecting the behaviour of radionuclide transfer to plants. Many parameters influence these processes.

One-year survey of cutaneous lesions in 1000 consecutive Iranian newborns.

Our objective was to study skin disorders in neonates within the first 48 hours of life in Ahvaz, Iran. One thousand consecutive neonates were examined in a descriptional prospective cohort study for 1 year (2002-03). The rate of skin disorders and their relationship to age of gestation and sex were calculated and analyzed using the computerized program SPSS version 10 and chi-squared test (chi2).
