The effect of Jordanian essential oil from coriander seeds on antioxidant, anti-inflammatory, and immunostimulatory activities using RAW 246.7 murine macrophages.

Coriander (Coriandrum sativum L.) is a member of the Umbelliferae/Apiaceae family and one of the well-known essential oil-containing plants, in which the seeds are used in traditional medicine, and as flavoring in food preparation. Knowing the diverse chemical components of different parts of the plant, this work aims to investigate the antioxidant, the anti-inflammatory, and the immunostimulatory modulator effects of the Jordanian C. sativum's seed extracted essential oil (JCEO). Coriander oil extract was prepared by hydro-distillation method using the Clevenger apparatus. Different concentrations of coriander oil were examined by using DPPH radical scavenging assay, MTT assay, pro-inflammatory cytokine (Tumor Necrosis Factor-TNF-alpha) production in RAW264.7 murine macrophages in addition, scratch-wound assessment, NO level examination, Th1/Th2 assay, phagocytosis assay, and fluorescence imaging using DAPI stain were conducted. JCEO had a potential metabolic enhancer effect at a concentration of 0.3 mg/mL on cell viability with anti-inflammatory activities via increasing cytokines like IL-10, IL-4, and limiting NO, INF-γ, and TNF-α release into cell supernatant. Antioxidant activity was seen significantly at higher concentrations of JCEO reaching 98.7% when using 100mg/mL and minimally reaching 50% at 12.5mg/mL of the essential oil. Treated macrophages were able to attain full scratch closure after 48-hrs at concentrations below 0.3mg/mL. The seed-extracted JCEO showed significant free radical scavenging activity even at lower dilutions. It also significantly induced an anti-inflammatory effect via an increase in the release of cytokines but reduced the LPS-induced NO and TNF-α production at 0.16-0.3mg/mL. In summary, coriander essential oil demonstrated antioxidant, anti-inflammatory, and immunostimulatory effects, showcasing its therapeutic potential at specific concentrations. The findings underscore its safety and metabolic enhancement properties, emphasizing its promising role in promoting cellular health.

The Antimicrobial Activity of Combination of Vitamin D3 and Omega-3 against Pathogenic Microorganisms.

BACKGROUND: Food supplements such as vitamin D3 and omega-3 have a significant role in activating the immune system and impacting the diversity of gut microbiota; thus, controlling the growth of invading pathogens indirectly. OBJECTIVE: This study aims to evaluate the direct antimicrobial activity of vitamin D3 and omega- 3 individually, combined together, and combined with low concentrations of gentamicin or amphotericin B against selected pathogenic microorganisms. In addition, this study hypothesizes the potential antimicrobial mechanism and recommends suitable studies to be conducted. METHOD: Minimum inhibitory concentration of different serial dilutions of vitamin D3 [0.7µg/mL-83.3µg/mL] or omega-3 [0.7mg/mL-100mg/mL] or combined [vitamin D3:1.3µg/mL-83.3µg/mL and omega-3:1.56mg/mL-100mg/mL] with/without antibiotic have been investigated on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans using check board technique. RESULTS: The highest concentration of vitamin D3 [83.3 µg/mL] demonstrated a complete eradication of the tested microorganisms. Conversely, omega-3 had a lower effect on them. The highest concentration of combining vitamin D3 and omega-3 with/without gentamicin resulted in a complete eradication of the S. aureus, E. coli and P. aeruginosa with a 6.8 to 7 log reduction. On the other hand, C. albicans was inhibited when using vitamin D3 [83.3 µg/mL] or when this concentration is combined with 100mg/mL of omega-3. However, when these two concentrations were added to amphotericin B the log reduction dropped to 0.45 suggesting antagonistic effect. CONCLUSION: These findings suggested that, unlike omega 3, vitamin D3 possesses good antimicrobial effects against pathogenic microorganisms. The combination of the studied food supplement showed enhanced microbial inhibition at high concentration, while they had antagonistic effect when combined with amphotericin B and applied on C. albicans combined. Further studies on the exact antimicrobial mechanism are still required to understand the measured data here.

Evaluation of immunomodulatory potential of probiotic conditioned medium on murine macrophages.

Probiotics are a mixture of beneficial live bacteria and/or yeasts that naturally exist in our bodies. Recently, numerous studies have focused on the immunostimulatory effects of single-species or killed multi-species probiotic conditioned mediums on macrophages. This study investigates the immunostimulatory effect of commercially available active, multi-species probiotic conditioned medium (CM) on RAW264.7 murine macrophages. The probiotic CM was prepared by culturing the commercially available probiotic in a cell-culture medium overnight at 37 °C, followed by centrifugation and filter-sterilization to be tested on macrophages. The immunostimulatory effect of different dilution percentages (50%, 75%, 100%) of CM was examined using the MTT assay, proinflammatory cytokine (tumor necrosis factor TNF-alpha) production in macrophages, migration, and phagocytosis assays. For all the examined CM ratios, the percentages of cell viability were > 80%. Regarding the migration scratch, TNF-alpha and phagocytosis assays, CM demonstrated a concentration-dependent immunostimulatory effect. However, the undiluted CM (100%) showed a significant (p-value < 0.05) stimulatory effect compared to the positive and negative controls. The findings suggest that the secretions and products of probiotics, as measured in the CM, may be closely associated with their immune-boosting effects. Understanding this relationship between probiotic secretions and immune function is crucial for further exploring the potential benefits of probiotics in enhancing overall health and well-being.

Diabetes and Cancer: Metabolic Association, Therapeutic Challenges, and the Role of Natural Products.

Cancer is considered the second leading cause of death worldwide and in 2018 it was responsible for approximately 9.6 million deaths. Globally, about one in six deaths are caused by cancer. A strong correlation was found between diabetes mellitus and carcinogenesis with the most evident correlation was with type 2 diabetes mellitus (T2DM). Research has proven that elevated blood glucose levels take part in cell proliferation and cancer cell progression. However, limited studies were conducted to evaluate the efficiency of conventional therapies in diabetic cancer patients. In this review, the correlation between cancer and diabetes will be discussed and the mechanisms by which the two diseases interact with each other, as well as the therapeutics challenges in treating patients with diabetes and cancer with possible solutions to overcome these challenges. Natural products targeting both diseases were discussed with detailed mechanisms of action. This review will provide a solid base for researchers and physicians to test natural products as adjuvant alternative therapies to treat cancer in diabetic patients.

Evaluation of the effect of video tutorial training on improving pharmacy students' knowledge and skills about medication reconciliation.

OBJECTIVES: This study aimed to describe the effect of using an innovative teaching strategy using a video tutorial on enhancing students' knowledge about medication reconciliation, and skills in identifying medication discrepancies. METHODS: This is a one group pre-post interventional study that was conducted at the School of Pharmacy at Applied Science Private University. Sixty pharmacy students were invited to attend an educational sessions that involve watching a 6-minutes video tutorial. The first two levels of the Kirkpatrick's Model were used to evaluate the effectiveness of this training tool. Level 1 (Reaction) was assessed using a satisfaction questionnaire, while level 2 (Learning) was assessed using two criteria: 1) student acquired knowledge about medication reconciliation using a questionnaire and a knowledge score out of 13 was calculated for each student, and 2) student acquired skills in identifying medication discrepancies using a virtual case scenario. If the student was able to identify any of the four impeded discrepancies he/she rewarded 1 point for each identified discrepancy, but if they identified any incorrect discrepancy they scored a negative point. RESULTS: Among the 60 students who registered to participate in the study, 49 attended the educational training (response rate 81.6%). The majority of them (n=44, 89.8%) were satisfied with the training process. Before the video tutorial, students showed an overall low knowledge score [4.08/13.0, SD 1.81], and low ability to identify discrepancies [0.72 identified discrepancies out of 4.0, SD 1.1]. Following the video tutorial, the overall knowledge score was improved (p<0.001), and students were able to identify more discrepancies after watching the video (p<0.001). CONCLUSION: In conclusion, video education has shown itself to be an effective method to educate pharmacy students.. This visualized method can be applied to other areas within pharmacy education. We encourage the integration of videos within the learning process to enhance students' learning experience and to support the traditional learning provided by the teaching staff.
