Development of active chitosan film containing bacterial cellulose nanofibers and silver nanoparticles for bread packaging.

The objective was to develop an active chitosan-based coating and to evaluate its effect on the shelf life and microbial safety of bread. Bacterial cellulose nanofibers (BCNF) and various levels (0.5%, 1%, and 2%) of silver nanoparticles (AgNPs) were in the chitosan (CS) film.

Prevalence of MRSA as an Infectious Agent in Sanitary Swimming Pools and Jacuzzis.

Introduction: Methicillin-resistant (MRSA) is considered resistant to beta-lactam antibiotic groups. Infection caused by this strain is more difficult to treat with antibiotics, and hence, it will be more dangerous. This study focused on detecting the Staphylococcus in sanitary swimming pools and Jacuzzis in Yazd city, Iran (2019).

A study of comparing two cognitive-behavioral workshop for college students: Sleep, wakefulness program and perseverance program.

Introduction And Aim: Researchers and specialists believe that health maintenance and improvement through university students, as a part of society, play a crucial role in community configuration which should not be ignored. Since there was a few studies in these fields, researchers have sought to explore how mentioned workshops is related to cognitive emotion regulation, anxiety, depression, and sleep quality for the student volunteers of Shiraz University of Medical Sciences.

Materials And Methods: In a randomized controlled trial, 152 students were allocated into the 3 equal groups (study1: "perseverance workshop" study2:"sleep and wakefulness workshop" and control group).

The effect of willpower workshop on anxiety, depression, and the excitement components in the students of Shiraz university of medical sciences.

Introduction And Aim: The current study aimed at evaluating the effect of willpower workshop on anxiety, depression, and the Granovsky excitement components among the students of Shiraz University of Medical Sciences in the academic year 2016--2017.

Materials And Methods: Students (140) were selected by the simple random sampling method and allocated into two equal groups of intervention (willing) and control, each of 52 individuals. Data collection instruments were the Garnefski cognitive emotion regulation scale and the Beck depression and anxiety inventories.

Relationship between Religious Orientation, Anxiety, and Depression among College Students: A Systematic Review and Meta-Analysis.

Background: Religious obligation helps people to develop mental health by creating internal commitment to special rules. This meta-analysis aimed to determine the relationship between religious orientation and anxiety among college students.

Methods: Major scientific databases including PubMed, Web of Science, Science Direct, EBSCO, ProQuest and PsycINFO were searched for original research articles published 1987-2016.

Feasibility of applying the LED-UV-induced TiO/ZnO-supported HPMoO nanoparticles in photocatalytic degradation of aniline.

In the present study, TiO/ZnO-supported phosphomolybdic acid nanoparticles are investigated by the impregnation method, followed by analyzing their photocatalytic activity under UV-LED light and degradation kinetics degrading aniline as an organic pollutant model. Nanoparticle characteristics and the remaining Keggin structure in the nanocomposites were confirmed by means of FESEM, FTIR, and XRD analyses. Heterogenization of phosphomolybdic acid on TiO and ZnO nanoparticles resulted in the improved light absorption intensity and decreased band gap of nanocomposites.

The role of nymph in transmission of enteric bacterial pathogens to internal organs in sheep.

is a worldwide zoonotic parasite belong to phylum Athropoda. When the eggs are swallowed by intermediate host, the larvae are released in intestine and reach the mesenteric lymph nodes (MLNs) and occasionally liver, lungs, heart, kidneys, spleen, and other body organs by the blood and lymph circulation. There are a few evidences showing transmission of microorganisms by migrating The aim of this study was to determine the role of nymph in transmission of enteric bacterial pathogens to internal organs of sheep.

Comparison of Three Different DNA Extraction Methods for as a Food Born Pathogen.

Background: One of the most important items in molecular characterization of food-borne pathogens is high quality genomic DNA. In this study, we investigated three protocols and compared their simplicity, duration and costs for extracting genomic DNA from .

Methods: The larvae were collected from the sheep's visceral organs from the Yazd Slaughterhouse during May 2013.

Cardiovascular, respiratory, and total mortality attributed to PM2.5 in Mashhad, Iran.

Poor air quality is one of the most important environmental problems in many large cities of the world, which can cause a wide range of acute and chronic health effects, including partial physiological disorders and cardiac death due to respiratory and cardiovascular diseases. According to the latest edition of the national standard for air quality, maximum contamination level is 15 μg/m(3) per year and 35 μg/m(3) per day. The aim of this study was to evaluate cardiovascular, respiratory, and total mortality attributed to PM2.

Equilibrium and kinetics of phosphorous adsorption onto bone charcoal from aqueous solution.

Pyrolysis of fresh sheep bone led to the formation of bone charcoal (BC). The structural characteristics of BC and surface area were determined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). N2 gas adsorption-desorption was analysed by Brunauer-Emmett-Teller isotherm model.

A study of the knowledge, attitudes, and practices (KAP) of the women referred to health centers for cardiovascular disease (CVDs) and their risk factors.

Hypertension, dyslipidemia, and diabetes are established risk factors for cardiovascular disease (CVD) morbidity and mortality. In the past decade a general increase in CVD risk factors in the population aged 65 and older, along with suboptimal control rates, have occurred. In this descriptive, cross-sectional study, the authors describe the knowledge, attitudes, and practices (KAP) of Iranian females regarding risk factors for CVD, in an attempt to help with the development of strategies to control risk factors and CVD.
