Predicting anionic surfactant toxicity to Daphnia magna in aquatic environment: a green approach for evaluation of EC values.

The median effective concentration (EC) is the concentration of a substance expected to produce a specific effect in 50% of the populations with a certain density under defined conditions. This parameter is expressed as an acute toxicity and is obtained via chemical toxicity testing. But, the laboratory work is time-consuming, expensive, and not eco-friendly.

Antiretroviral therapy adherence based on information, motivation, and behavioral skills model and its association with depression among HIV-positive patients: Health promotion strategy towards the 909090 target.

Background: HIV-infected patients with poor antiretroviral therapy (ART) adherence are prone to depression, and depression can exacerbate the disease condition. This study was conducted to determine ART Adherence based on Information, Motivation, and Behavioral Skills (IMB) Model and its association with depression among HIV-positive patients.

Materials And Methods: This descriptive-correlational study was carried out on people over the age of 18 years with HIV/AIDS, who referred to the Behavioral Diseases Counseling Center in Kerman City, Iran, in 2017.

Adherence to Medication and Physical Activity among People Living with HIV/AIDS.

Background: The aim of this study was to investigate the adherence to medication and Physical Activity (PA) among People Living with HIV (PLHIV).

Materials And Methods: In the present cross-sectional study, 122 PLHIV were selected. The research tools included the Baecke questionnaire and the AIDS Clinical Trials Group questionnaire.

The effect of macroeconomic indicators on health-care expenditure in Iran.

Introduction: A sharp increase in expenditure is one of the challenges of the health system in Iran. Every macroeconomic variable affects health, and if it is disregarded, it will lead to higher macrobudgets. Physical and mental health as well as the use of health services change according to the macroeconomic conditions and business cycles (boom and recession).

Calibration of water quality model for distribution networks using genetic algorithm, particle swarm optimization, and hybrid methods.

Chlorine reacts with both organic and inorganic matters in water. That is why water quality modeling has received great attention in recent years. The serious issue in municipal water quality modeling is gathering the essential input parameters of the model, particularly bulk decay (k) and wall decay (k) coefficients as well as their calibrations.

Antiretroviral therapy adherence and its determinant factors among people living with HIV/AIDS: a case study in Iran.

Objectives: This descriptive-correlational study was conducted on 122 Iranian people living with HIV (PWHIV), who referred to a behavioral diseases counseling center in 2018. The AIDS Clinical Trial Group (ACTG) questionnaire was used to collect the required data. The study aimed to determine the level of medication adherence and its determinants in PWHIV.

Effect of the Living Environment on falls among the Elderly in Urmia.

Background: The living environment has an impact on the health of the elderly, and the safety of the house is one of the concerns of the elderly. Disregarding the safety concerns increases the falling.

Aim: This research was conducted with the aim of influencing the living environment on falls among elderly people in Urmia city.

Introduction: The present study aimed to assess the behavioral and familial predictors of diabetes mellitus as well as their interaction in the risk of diabetes mellitus type2.

Methods: The present cross-sectional study was conducted using the Yazd health study (YaHS) data which was collected in 2013-14. Statistical population of this study consisted of all 9340 individuals aged between 20 and 69 in Yazd City.

Cox Regression and Parametric Models: Comparison of How They Determine Factors Influencing Survival of Patients with Non-Small Cell Lung Carcinoma.

Background and objectives: The present study of survival rate of patients with non-small cell carcinoma (NSCLC) compared the efficiency of Cox semi-parametric vs. parametric models in determination of influencing factors. Methods: In this retrospective cohort study, data were gathered from 190 patients with a confirmed diagnosis of NSCLC referred to Shahid Sadoughi and Shohadaye Kargar Hospitals in Yazd, Iran during 2005 to 2014.

The effect of educational intervention on weight loss in adolescents with overweight and obesity: Application of the theory of planned behavior.

Background: The increased prevalence of overweight and obesity in children and adolescents is associated with type 2 diabetes, hypertension, dyslipidemia, and cardiovascular diseases. The theory of planned behavior (TPB) efficiently explains the ability of perceived behavioral control and possibly attitude to enhance the motivations of the obese people to lose weight. Our aim was to investigate the effect of TPB-based education on weight loss in obese and overweight adolescents.

Effects of bee propolis supplementation on glycemic control, lipid profile and insulin resistance indices in patients with type 2 diabetes: a randomized, double-blind clinical trial.

Background: Propolis, a natural resinous substance made by bees from material extracted from plants, flowers and bee's wax, has shown great therapeutic effects and been widely used in food and drug industries. Recently, some researchers have studied the effect of this substance in the treatment of diabetes.

Objective: The purpose of this trial was to determine the effect of bee propolis on glycemic control, serum lipid profile and insulin resistance indices in patients with type 2 diabetes (T2D).

Self Management Behaviors in Rheumatoid Arthritis Patients and Associated Factors in Tehran 2013.

Introduction: Rheumatoid Arthritis (RA) is a systemic, autoimmune and inflammatory disease with an unknown etiology that is associated with progressive joint degeneration, limitation of physical activity and disability. The aim of the study was to evaluate self-management behaviors and their associated factors in RA patients.

Material & Method: This cross-sectional study was performed in 2013 on185 patients in Iran.

Comparison between Ag (I) and Ni (II) removal from synthetic nuclear power plant coolant water by iron oxide nanoparticles.

The impact of effective parameters such as iron oxide nanoparticles dosage, contact time and solution pH was optimized for removal of Ag(I) and Ni(II) in the nuclear cooling system and the best conditions were compared. Nearly complete removal (97%) of Ni(II) and Ag(I) were obtained at adsorbent dosage of 40 and 20 g/L, respectively. Experiments showed that 4 hours was a good choice as optimum contact time for two ions removal.
