Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...

R-factor 1818 (R-1818) had no effect on the efficiency of plating of ligase-deficient phage T4 mutants on strains of Escherichia coli containing excess, normal, or defective ligase. However, if the R(+) bacterial strain that overproduced ligase was first starved of thymine, its ability to propagate ligase-deficient phage was reduced by as much as fivefold compared with the burst size on the thy...

Silica-gold nanoshell (SGNS), which is a silica core surrounded by a gold layer, was synthesized by seed-mediated coalescence of gold clusters in an electroless plating solution. SGNS variations with different surface coverage of gold clusters were prepared by adjusting the amounts of gold salts in the presence of formaldehyde-reducing agents. Fully covered SGNS (f-SGNS) with connected gold clu...

BACKGROUND Radiotherapy of the thorax often causes lung inflammation leading to fibrosis. OBJECTIVES The aim of this study was to investigate whether the use of glycyrrhizic acid (GLA) could improve the development of lung fibrosis in irradiated animals. MATERIALS AND METHODS Wistar rats were divided into four groups. Group A rats received thoracic irradiation. Rats in group B received GLA ...

The objective of the present study was to assess the growth and the recovery of Salmonella (S.) Enteritidis SE86 in different diluents, culture media and using different plating methods after the exposure to 200 mg/kg sodium dichloroisocyanurate (NaDCC). Before and after NaDCC exposure, SE86 was cultured at 30 °C and 7 °C in the following diluents: Peptone water (P), Saline solution (SaS), Pept...
