Anxiety-like behavior induced by allergen is associated with decreased irregularity of breathing pattern in rats.

Allergic rhinitis (AR) is a chronic inflammatory disorder associated with a high prevalence of anxiety symptoms and respiratory disorders that adversely affect the quality of life. Studies have shown that allergen exposure induces anxiety-like behaviors. On the other hand, stress impairs the breathing pattern.

Investigating the relationship between quality of life and hope in family caregivers of hemodialysis patients and related factors.

Background: Family caregivers of hemodialysis patients are the first and most crucial source of care at home. They experience many problems in the care of hemodialysis patients, which can affect their quality of life and hope, affecting the quality of care provided to patients. This study aimed to determine the relationship between quality of life and hope in family caregivers of hemodialysis patients.

Optical and electrochemical aptasensors for the detection of amphenicols.

Various methods have been introduced to detect amphenicols in biological samples. However, because of some problems involved in conventional methods, such as time-consuming processes, expensive equipment, and high consumption of reagents, novel strategies for the detection and quantitative determination of amphenicols are required. Aptamer-based biosensors with unique recognition features have gained much attention because of their rapid response, high specificity, and simple fabrication.

Development and characterization of DNA aptamers against florfenicol: Fabrication of a sensitive fluorescent aptasensor for specific detection of florfenicol in milk.

Specific ssDNA aptamers for the antibiotic florfenicol (FF) were developed from an enriched nucleotide library using magnetic beads-based SELEX (Systematic Evolution of Ligands by EXponential enrichment) technique with high-binding affinity. After 12 rounds of selection, thirty-six sequences were obtained that were then divided into five major families, according to the primary sequence similarity. Binding affinity analyses of three fluorescently tagged aptamers belonging to different families demonstrated that the dissociation constants (K) were in the low nanomolar range (K = 52.

Comparison of Apical Transportation with the Use of Rotary System and Reciprocating Handpiece with Precurved Hand Files: An Study.

Introduction: Success of root canal treatment depends on several factors; among which, maintaining the original canal path during mechanical preparation is extremely important. This study aimed to compare apical transportation using RaCe NiTi rotary system and precurved stainless steel (SS) hand files in a reciprocating handpiece.

Methods And Materials: Mesiobuccal canals of 40 extracted human mandibular first and second molars with 20 to 45 curvatures and 3 to 7 mm curve radius were chosen for this study.

Relationship between Spiritual Health and Quality of Life in Patients with Cancer.

As the essence of health in humans, spiritual health is a fundamental concept for discussing chronic diseases such as cancer and a major approach for improving quality of life in patients is through creating meaningfulness and purpose. The present descriptive analytical study was conducted to assess the relationship between spiritual health and quality of life in 210 patients with cancer admitted to the Cancer Institute of Iran, selected through convenience sampling in 2014. Data were collected using Spiritual Health Questionnaire and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ).
