Green Synthesized of Thymus vulgaris Chitosan Nanoparticles Induce Relative WRKY-Genes Expression in Solanum lycopersicum against Fusarium solani, the Causal Agent of Root Rot Disease
: Fusarium solani is a plant pathogenic fungus that causes tomato root rot disease and yield losses in tomato production. The current study's main goal is testing the antibacterial efficacy of chitosan nanoparticles loaded with Thyme vulgaris essential oil (ThE-CsNPs) against F. solani in vitro and in vivo. GC-MS analysis was used to determine the chemical constituents of thyme EO. ThE-CsNPs were investigated using transmission electron microscopy before being physicochemically characterized using FT-IR. ThE-CsNPs were tested for antifungal activity against F. solani mycelial growth in vitro. A pot trial was conducted to determine the most effective dose of ThE-CsNPs on the morph/physiological characteristics of Solanum lycopersicum, as well as the severity of fusarium root rot. The relative gene expression of WRKY transcript factors and defense-associated genes were quantified in root tissues under all treatment conditions. In vitro results revealed that ThE-CsNPs (1%) had potent antifungal efficacy against F. solani radial mycelium growth. The expression of three WRKY transcription factors and three tomato defense-related genes was upregulated. Total phenolic, flavonoid content, and antioxidant enzyme activity were all increased. The outfindings of this study strongly suggested the use of ThE-CsNPs in controlling fusarium root rot on tomatoes; however, other experiments remain necessary before they are recommended
Health promotion, disease prevention and periodic health checks: perceptions and practice among family physicians in Eastern Mediterranean region
Introduction: The aim of this study was to identify the current practices and perceptions of family physicians regarding health promotion, disease prevention including periodic screening and health checks in Eastern Mediterranean Region. Methods: A multi-country cross-sectional study was conducted in six countries of EMR, from September 2014 to March 2015. Family Physicians who were currently practicing in different countries of EMR were invited to participate in the study through email. A pre-tested structured questionnaire was used for data collection. Data was entered and analyzed on SPSS 19 and logistic regression analysis was performed. Results: A total of 100 physicians’ data was included in the final analysis. The majority were female physicians (76%): 63% were 25 to 35 years of age. Approximately 53% of Family physicians always recommend periodic screening and health checks to their patients. The common screening question asked to patients in medical history was related to their blood pressure (86%). Almost all (99%) of the Family physicians believe they should conduct periodic health checks. Those who had postgraduate training in Family Medicine (OR: 0.5; 95% CI: 0.39-1.67) and attended CME sessions regularly (OR: 0.11; 95% CI: 0.01-0.93), are more likely to recommend periodic screening and health checks to their patients. Conclusion: Periodic screening and health check is an important strategy to prevent disease and maintain health. It is an underutilized practice and a great need exists for its implementation in family practice
Barriers, challenges and way forward for implementation of person centered care model of patient and physician consultation: a survey of patients’ perspective from Eastern Mediterranean countries
Background: Person-Centered Care (PCC) is now considered a mandatory approach in Patient-Physician consultation. The aim of the study was to identify patients’ perception regarding barriers and possible remedies for implementation of PCC in Eastern Mediterranean Region (EMR). Methods: A cross-sectional multi-country study was conducted in six countries of EMR during May 2014 to October 2014. Expert Family Physicians from each country were identified and asked to participate in the study. The Family Physicians then recruited Patients from their own clinics (\u3e18 years). Data analysis was performed on SPSS 19 and results are reported in the form of proportions, odds ratios and 95% confidence intervals. Results: A total of 234 patients were recruited, 60.6% were aged between 20 to 30 years and 36.3% of them were males. 56% of the patients preferred Person-Centered Care model for patient-physician consultation. The major barriers identified by patients in its implementing were; time constraints (73.9%, OR: 1.5; 95% CI: 0.86-2.78), doctors desire to control patient (OR: 2.6; 95% CI: 1.55-4.49), cultural and religious reasons (52.1%), increased cost (50.9%). Patients responded that increased cost related to Person-Centered Care practice would be acceptable (58.1%), if increase proved to be in the interest of better health and care outcomes (40.6%). Conclusion: Person-Centered Care (PCC) is associated with significant barriers in its implementation in Eastern Mediterranean Region. These barriers can be overcome in the interest of better health and care related outcomes
On Some Dynamics of Duffing Dynamical System Generated by a Semi-Discretization Process with Two Different Delays
Abstract: In this paper, a semi-discretization process is applied to the Duffing system to obtain its continuous time difference equations counterpart with two different delays. Fixed points and their asymptotic stability of the resulting system are investigated. Bifurcation and chaos are discussed
Guidance on risk assessment for animal welfare
The document provides methodological guidance to assess risks for animal welfare, considering the various husbandry systems, management procedures and the different animal welfare issues. The terminology for the risk assessment of animal welfare is described. Risk assessment should not be carried out unless the relevant welfare problem is clearly specified and formulated. The major components of the problem formulation are the description of the exposure scenario, the target population and the conceptual model linking the relevant factors of animal welfare concern. The formal risk assessment consists of exposure assessment, consequence characterisation, and risk characterisation. The systematic evaluation of the various aspects and components of the assessment procedure aims at ensuring its consistency. All assumptions used in problem formulation and risk assessment need to be clear. This also applies to uncertainty and variability in the various steps of the risk assessment. The choice between qualitative, semi-qualitative or quantitative approaches should be made based on the purpose or the type of questions to be answered, data, and resource availability for a specific risk assessment. Quantitative data should be used whenever possible. Positive effects on welfare (benefit) could be handled within the framework of risk assessment if the analysis considers factors as having both positive and negative effects on animal welfare. The last section details the main components of risk assessment documentation
