ABSTRACT

       Background and Objective: Raw fish is a highly perishable product that deteriorates due to chemical changes and microbial growth. Biogenic amines (BAs) are generated in course of bacterial spoilage in fish that may lead to BA toxicity, particularly in adverse storage conditions. The purpose of this study was to prevent the BAs toxicity caused by common carp (Cyprinus carpio).

       Methods: Live Common carps were purchased from a local market. The samples were first divided into control and lactic acid treatment groups, and then stored at 4 C. the  concentrations of three BAs were determined (histamine, putrescine and cadaverine) with high performance liquid chromatography equipped with UV detector.

        Results: Cadaverine and putrescine had the highest concentrations in control group (400.42 and 293.90 mg/kg, respectively). Histamine remained undetectable until the middle of storage period. Histamine and cadaverine concentrations in the lactic acid group were significantly lower compared to that of control group (p < 0.05).

         Conclusion: The formation of histamine and cadaverine is effectively controlled by lactic acid treatment, although such effect was not observed on putrescine in the entire storage period.

          Keywords: Biogenic Amines, Toxicity, Carps, Histamine.

Abstract

ABSTRACT
             Background and Objectives: Cancer and its conventional treatments may bring about some psychological and health-related symptoms leading to unstable cortisol level. Since evidence has shown that mindfulness based approaches can be helpful to reduce cortisol level, we aimed at investigating the efficacy of   mindfulness-based cognitive therapy (MBCT) on decreasing salivary cortisol level in the women with breast cancer. 
             Methods: in this one- group pretest posttest study, the women with early stage breast cancer were assessed to select eligible ones (N = 15). They were first trained for collecting salivary cortisol sample (before, after and follow-up)   and then were asked to participate in MBCT, an eight-week session approach.  Participants provided salivary samples in the morning (7: 30- 8:30), afternoon (1-3) and night (9-11).  To measure cortisol, Cortisol Enzyme Immunoassay Kit was used. Analysis was performed on the data of 12 participants remained, using repeated measurement.
              Results: the results of repeated measure ANOVA revealed that cortisol level of posttest (after 8-weeks of MBCT and follow-up period) in comparison with pretest was significantly reduced for morning and afternoon cortisol while it was not true for night cortisol.  The post-treatment cortisol was not significantly correlated with age groups, education levels and socio-economic status using repeated measure ANCOVA.   
             Conclusion: Given that the women with breast cancer are at the high risk of psychological distresses and unstable cortisol level, we recommend mindfulness-based approaches esp. MBCT to health providers specifically those working with breast cancer patients.
             Keywords: Mindfulness, MBCT, Cortisol , Salivary Cortisol, Breast cancer.

ABSTRACT
             Background and objectives: Utilization of essential oils instead of chemical preservatives has received significant attention in recent years. The present study aims to evaluate chemical composition and antibacterial and antioxidant properties of essential oils of Zataria multiflora, Artemisia deracunculus and Mentha piperita.
             Methods: Chemical profile of the essential oils was analyzed by gas chromatography/mass spectrometry. The microwell dilution and agar disk diffusion methods were used to evaluate the antibacterial properties of the essential oils. Total phenolic content, β-carotene-linoleic acid bleaching test and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays were carried out to determine the antioxidant properties.
             Results: Menthol (39.18%) and mentone (21.64%) were the main components of the essential oil of M. piperita, while estragol (34.75%) and limonene (15.72%) were the major components of the essential oil of A. dracunculus. The main components of the essential oil of Z. multiflora were carvacrol (36.81%) and thymol (33.04%). The essential oils of M. piperita and Z. multiflora showed greater antimicrobial effects. Moreover, Z. multiflora showed the greatest antioxidant activity among the essential oils. The total phenolic content of Z. multiflora was 228.14±0.45 mg gallic acid equivalent/g.
             Conclusion: Given their favorable antioxidant and antimicrobial properties, the essential oils of Z. multiflora, A. deracunculus and M. piperita can be used as natural food preservatives.
             Keywords: Zataria multiflora, Artemisia deracunculus, Mentha piperita, antibacterial effect, antioxidant effect.
