Efficacy and safety of radiofrequency in the treatment of hidradenitis suppurativa; a systematic review.

Background And Aims: Hidradenitis suppurativa (HS) is an inflammatory skin disease affecting apocrine gland-bearing sites of the body. Radiofrequency (RF) is a minimally invasive method that acts by minimizing thermal damage to the dermis, resulting in collagen synthesis and scar improvement. We systematically reviewed the efficacy and safety of RF in treating HS.

The Influence of Face Masks on Verbal Communication in Persian in the Presence of Background Noise in Healthcare Staff.

Wearing face masks has resulted in verbal communication being more challenging during the COVID-19 pandemic. This study aimed to investigate the effect of face masks on the speech comprehensibility of Persian nurses in healthcare settings. Twenty female nurses from the governmental hospitals randomly participated in an experiment on seven typical commercial face masks at two background noise levels.

Maternal death of a hemophilic patient due to the inhaling of a mixture of industrial bleach and detergents-A case study.

Use of detergents and cleaning products puts women at risk due to hazardous chemical substances. Education of all women, especially pregnant and high-risk women about the proper use of detergents, is a necessity.

Immobilization of cytochrome c and its application as electrochemical biosensors.

Cytochrome c (Cyt c) has been used as a model protein to investigate the characters of modified electrodes by many researchers. It has been also employed to construct biosensors to detect hydrogen peroxide, nitrate, superoxide, and etc. Cyt c immobilization techniques, including physical adsorption, entrapment in hydrogel or polymers, layer-by-layer assembly, Langmuir-Blodgett, and covalent attachment are discussed followed by various electrochemical methods applied in the electrode modification.

A highly sensitive kinetic spectrophotometric method for the determination of ascorbic Acid in pharmaceutical samples.

In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm.
