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 ...

Background: The theory of selective photo-thermolysis led to the development of a variety of different laser systems which range from the shorter spectrum of 694nm ruby laser to the middle with the 755nm alexandrite and 810nm diode lasers to the long end with the 1064nm (Nd:YAG) laser. Objective: A systematic review on the clinical trials with use of various laser sources for hair removal...

among the drug delivery and targeting (ddt) routes, lung alveolar epithelium has been given enormous attentions in terms of the delivery of a wide range of macromolecules such as gene- or protein-based nanopharmaceuticals. however, little is known about cellular modulation of lung transport characteristics by endogenous and/or exogenous agents. thus, in the current study, impact of dexamethason...

introduction bacterial infection is one of the major causes of morbidity and mortality especially in developing countries. nuclear medicine has an important role in helping the diagnosis of deep-seated infections by developing more specific radiopharmaceuticals. the aim of this study was to evaluate 99mtc-labeling ceftriaxone as a new radiopharmaceutical for staphylococcus aureus infection imag...

in this paper i develop a proxy means tests (pmt) model and examine several targeting lines based on 2008 household survey data to identify beneficiaries for a targeting subsidy scheme in iran. based on the findings of this study, setting a cut-off percentile of 40% is expected to provide compensation for almost 70 percent of the poorest households. this will result in the highest accuracy main...

The primary purpose of obtaining laser targeting devices for C-arm fluoroscopy was to attempt to reduce radiation to the pediatric population in Connecticut Children's Medical Center's commitment to Imaging Gently. Fluoroscopy times for placing central lines in the operating rooms were documented for two months prior to the installation of the lasers and then for twenty procedures after install...

Background: Laser-tissue interaction on low-level laser therapy (LLLT) has widespread medical applications (e.g., improved wound healing). The tensile strength of radiated tissue by LLLT is known to be increased mainly because of cross collagen bands developed after radiation.Objective: In this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic ti...
