Dosimetric evaluation of Rhizophora spp. particleboard bonded with animal protein adhesive at X-ray energies below 100 kVp.

This research developed a bio-based adhesive (AP) derived from industrial slaughterhouse waste, comprising over 85% protein. The adhesive was characterized by a melting point of 193.14 °C, a neutral pH of 7, and a viscosity comparable to common wood adhesives such as urea-formaldehyde and phenol-formaldehyde.

Correlation of acidic mammalian chitinase expression with disease severity in patients with moderate/severe persistent allergic rhinitis.

Aim Of The Study: To assess the level of acidic mammalian chitinase (AMCase) expression and IL-8 in nasal inferior turbinate mucosa in patients with mild and moderate to severe allergic rhinitis (AR).

Material And Methods: Participants in this case-control study were divided into three groups, including patients with moderate and severe persistent allergic rhinitis, cases with mild forms of persistent AR, and control or healthy group. We obtained biopsies of nasal inferior turbinate mucosa from all participants.

Impact of low level radiation on concentrations of some trace elements in radiation workers.

Introduction: Small variations in trace element levels may cause important physiological changes in the human body. This study aims to evaluate five important trace elements in radiation workers.

Method: In this study, 44 radiation workers and an equal number of non-radiation workers were selected as the case and control group, respectively.

Gold-Gold Sulfide nanoparticles intensify thermal effects of radio frequency electromagnetic field.

Purpose: This study aimed to determine the efficacy of thermotherapy resulting from the presence of gold-gold sulfide nanoshells (GGS) in radio frequency electromagnetic field (13.56 MHz) onthe survival of CT26 colon carcinoma cells.

Materials And Methods: GGS was synthesized and after characterizing and determining the features, the RF-radiation effects on aquatic environments were determined by recording temperature changes.

Gold-gold sulfide nanoshell as a novel intensifier for anti-tumor effects of radiofrequency fields.

Objectives: Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells.

Materials And Methods: Synthesis and characterization of GGS nanoshells were initially performed.

Silver nanoparticles increase cytotoxicity induced by intermediate frequency low voltages.

Electrical properties of the cells play a key role in biological processes. Intermediate frequencies of electrical fields influence the cells proliferation without heat generation and electrical stimulation. Silver nanoparticle (SNP) as a metallic agent can change the electrical characteristics of the cells.

A Comparison Between GATE and MCNPX Monte Carlo Codes in Simulation of Medical Linear Accelerator.

Radiotherapy dose calculations can be evaluated by Monte Carlo (MC) simulations with acceptable accuracy for dose prediction in complicated treatment plans. In this work, Standard, Livermore and Penelope electromagnetic (EM) physics packages of GEANT4 application for tomographic emission (GATE) 6.1 were compared versus Monte Carlo N-Particle eXtended (MCNPX) 2.

An in vitro study on the photosensitivity of 5-aminolevulinic acid conjugated gold nanoparticles.

Background: In this study, the photosensitivity of 5-aminolevulinic acid (5-ALA) conjugated gold nanoparticles (conjugate) has been investigated on the MeL-Rm cell line.

Methods: After culture and proliferation of the Mel-Rm cell line, cell toxicity and the suitable cell incubation time of the conjugate were determined. Photosensitivity of the conjugate and free 5-ALA was then studied in optical doses of 20, 40, 60 and 80 J/cm(2) while light irradiation was applied by a He-Ne laser.

Effective dose of topiramate in pediatric migraine prophylaxis.

Objective: Migraine is a common neurological disorder in childhood and adolescence. Topiramate is a new anticonvulsant drug, recently being used in migraine prophylaxis in adults, although it is not approved by the Food and Drug Administration for prevention of pediatric migraine. The present study was planned and performed to evaluate the efficacy of low-dose topiramate in pediatric migraine prophylaxis.

Estimation of human effective absorbed dose of 67Ga-cDTPA-gonadorelin based on biodistribution rat data.

Objective: In this investigation, we estimated the effective absorbed dose of radiation into human organs, after an intravenous administration of gallium-67 (67Ga)-labeled gonadorelin, one of the gonadotropin-releasing hormone (GnRH) agonists, using biodistribution data from injected normal rats.

Methods: Five rats were killed at exact time intervals (0.25, 0.

Determination of human absorbed dose of 67GA-DTPA-ACTH based on distribution data in rats.

The absorbed radiation dose to human organs has been estimated, following intravenous administration of (67)Ga-labelled adrenocorticotrophic hormone (ACTH) using distribution data from injected normal rats. Four rats were sacrificed at exact time intervals and the percentage of injected dose per gram of each organ was measured by direct counting from rat data. The Medical Internal Radiation Dose formulation was applied to extrapolate from rat to human and to project the absorbed radiation dose for various organs in a human.
