Meat is prone to contamination and spoilage due to its composition and production. Therefore, in order to extend its shelf life, the use of antioxidant and antimicrobial compounds has always been the focus of researchers' attention.The present study was conducted to evaluate effects of edible chitosan (2%) coating containing Cuminum cyminum essential oil (1%) on the shelf-life of meat in modified atmosphere packaging at refrigerated storage. The meat samples were separated into three groups uncoated (control), treated with chitosan coated without Cuminum cyminum essential oil and immersed in chitosan coated with Cuminum cyminum essential oil.
 Then Samples were packed in MAP (80% O2 and 20% CO2) conditions and stored at 4°C up to 21 days and evaluated periodically (on days 0, 3, 6, 9, 12, 15, 18 and 21) for microbiological (Total microbial counts, lactic acid bacteria, Enterobacteriaceae and Pseudomonas spp.) and chemical (pH, TBA and TVN) characteristics. Microbial analysis indicated that coating had significant influence (p<0.001) on reduction of increasing trends of Total microbial counts, lactic acid bacteria, Enterobacteriaceae and Pseudomonas spp.bacteria. From the aspects of chemical factors, the containing chitosan coating groups showed lower pH, TBA and TVN than those without coating. According to the results, chitosan coating significantly improved (P<0.05) quality of samples. This study also indicated that the effect of chitosan containing Cuminum cyminum essential oil on samples was to retain their good quality characteristics and extend the shelf life during refrigerated storage, which was supported by the results of microbiological, chemical, and sensorial properties.

Due to the high amount of pH, moisture and protein content, chicken meat is a sensitive product which could be a good host for pathogen and spoilage microorganisms. In the recent years there has been a remarkable attention to use natural preservative instead of chemical preservative among producers of food products. Different studies has shown rosemary essential oil contain antioxidant and antimicrobial properties. The present study was conducted to evaluate effect of rosemary essential oil (free and nanoemulsion) on chemical, microbial and sensorial quality of chicken fillet during refrigerated storage. Samples were examined in days of 0, 3, 6, 9 and 12. The results showed noticeable effects of both forms of rosemary essential oils in microbial, chemical and sensorial quality improvement. Moreover the results indicated that nanoemultion form of rosemary had significant effects on delaying the increase trend of psychrophilic, ,enterobacteriacea and mesophilic bacterial counts as compared to free form of rosemary (P<0.05). Furthermore The results of TVN, TBA and pH measurements indicated that nanoemulsion form of rosemary improved chemical quality of the samples in comparison with free form of rosemary during storage time (P<0.001).  Also in terms of sensorial characteristics, application of nanoemulsion essential oil lead to improvement of odor and overall acceptance factors compared to control group after twelve days of storage.

Although fish oil is a very important source of omega-3 and its consumption is recommended in terms of nutrition, it cannot be used directly in the food system due to its instability. Therefore, its stability can be increased by converting the particle to the nanoscale. The aim of this study was to investigate the physical and chemical stability of omega-3 nanoemulsion at different temperatures and its antibacterial properties. For this purpose, fish oil containing omega-3 fatty acids was produced by high energy method in nanoparticles and its physical (particle size, zeta potential, viscosity, and physical stability) and chemical properties (pH and turbidity) were evaluated during storage at 4, 25 and 40 ^o C during 7 days, as well as antibacterial properties of fish oil nanoemulsion against two gram-positive and gram-negative bacteria. The results showed that the omega-3 nanoemulsion produced had the optimum stability at 25 o C. the optimal concentration of 4% of omega-3 nanoemulsions also showed antibacterial properties against the studied bacteria, especially Staphylococcus aureus.

Nowadays, technology and smart phones have become a necessity. Satisfying customer or consumer about using this technology has become a competitive issue, and this competition exist in each and every region with no exception. The aim of this study is to survey the impact of the quality including quality of content, system quality and service quality, on perceived hedonistic and utility, and on customer satisfaction. In terms of aim, this study is applied and it is also a descriptive - causal study. Population of this study is Samsung Smartphone customers in Khorramabad city; study sample consist of 300 respondents which were randomly selected. Data analyzed using descriptive and inferential statistics in SPPS (22.0) and AMOS (21) software. Results show that all hypotheses were accepted.

Thyrotoxicosis is the name given to the clinical manifestations of the excess of thyroid hormones in the bloodstream. Thyrotoxicosis may induce increased fasting blood sugar (FBS) in patients of all ages, and has been reported in only few cases. The previous studies have shown that the prevalence of glucose intolerance in hyperthyroidism is 44-65% and may reverse to normal values after achieving euthyroid status. We discuss a 34-year-old woman who presented with thyrotoxicosis with enhanced FBS. The patient had a mild elevated FBS (110 mg/dl) when she had a severe thyrotoxicosis. After treatment with methimazole blood glucose level decreased to 85 mg/dl and by the third visit glucose level decreased to 82 mg/dl. It could be concluded that Mild hyperglycemia may co-exist with thyrotoxicosis and reduce to normal when the patient becomes euthyroid. Thus, early detection and treatment of thyroid hormones oversecretion can resolve the complications of both thyrotoxicosis and associated hyperglycemia.

Background:
SARS-CoV-2 which first was observed in Wuhan region, China in December 2019 has affected many organs, such as central nervous system. We describe a case of a 57-year-old male patient, in the hospital with the loss of consciousness, in the form of lack of verbal and visual communication. He got a seizure attack for about 3 minutes in the form of generalized tonic-clonic seizure (GTS) and admitted to the neurological department and was intubated. Since, the patient was not aware, awake, did not obey, corneal reflexes test was positive and his pupils were isochoric and reactive therefore, the primary diagnosis was cerebrovascular accident (CVA). On the second day after admission, although the brain computed tomography (CT) did not show brain lesion, but the chest X-ray (CXR) revealed lung involvement. In addition, on third day the RT-PCR test for coronavirus RNA in and the cerebrospinal fluid and nasopharyngeal swap done and the result was positive for both of them. Therefore, treatment for the covid-19 was started.
Results:
Since, the treatment for the covid-19 was started with Atazanavir, Clindamycin and Ceftriaxone. Ten days after hospitalization, the lung involvement and general condition of patient got better and after two weeks he was released from the hospital.
Conclusion:
GTS should be considered as a neurological outcome of COVID-19 and medications against the coronavirus, such as Atazanavir, Clindamycin and ceftriaxone can recover the neurological deficits in these patients.
