Abstract Title:
In vitro antiviral activity of Griffithsin against porcine epidemic diarrhea virus.
Abstract:
Griffithsin is a lectin with potent antiviral activity against enveloped viruses. The objective of this study was to assess Griffithsin's inhibitory effect on porcine epidemic diarrhea virus (PEDV). The results showed that Griffithsin reduced PEDV infection of Vero cells by approximately 82.8%. Moreover, using time-of-addition assays and RT-qPCR, we found that delayed addition of Griffithsin had a weaker inhibitory effect on PEDV than earlier treatment. The mechanism of Griffithsin's action against PEDV involved both preventing viral attachment to host cells and disrupting cell-to-cell transmission; its dual mode of action distinguished Griffithsin from most other antiviral drugs. In conclusion, Griffithsin was identified as a potent PEDV inhibitor and may represent a candidate drug for preventing PEDV infection.

Abstract Title:
Natural product-derived phytochemicals as potential agents against coronaviruses: A review.
Abstract:
Coronaviruses are responsible for a growing economic, social and mortality burden, as the causative agent of diseases such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), avian infectious bronchitis virus (IBV) and COVID-19. However, there is a lack of effective antiviral agents for many coronavirus strains. Naturally existing compounds provide a wealth of chemical diversity, including antiviral activity, and thus may have utility as therapeutic agents against coronaviral infections. The PubMed database was searched for papers including the keywords coronavirus, SARS or MERS, as well as traditional medicine, herbal, remedy or plants, with 55 primary research articles identified. The overwhelming majority of publications focussed on polar compounds. Compounds that show promise for the inhibition of coronavirus in humans include scutellarein, silvestrol, tryptanthrin, saikosaponin B, quercetin, myricetin, caffeic acid, psoralidin, isobavachalcone, and lectins such as griffithsin. Other compounds such as lycorine may be suitable if a therapeutic level of antiviral activity can be achieved without exceeding toxic plasma concentrations. It was noted that the most promising small molecules identified as coronavirus inhibitors contained a conjugated fused ring structure with the majority being classified as being polyphenols.

Abstract Title:
Experience of Music Used With Psychedelic Therapy: A Rapid Review and Implications.
Abstract:
Bonny Method of Guided Imagery and Music emerged following discontinuation of psychedelic therapy research in the early 1970s, but psychedelic therapy research has since revived. Music remains a vital component. This study examined participants' experiences of music in psychedelic therapy research. A rapid review of qualitative and quantitative journal articles in four major databases was conducted in February to April, 2019, using the terms hallucinogens, psychedelic,"lysergic acid diethylamide,"psilocybin, ayahuasca, music, and/or"music therapy."Of 406 articles retrieved, 10 were included (n = 180; 18-69 years old). Participants had varied backgrounds. Music was widely considered integral for meaningful emotional and imagery experiences and self-exploration during psychedelic therapy. Music transformed through its elicitation of anthropomorphic, transportive, synesthetic, and material sensations. Music could convey love, carry listeners to other realms, be something to"hold,"inspire, and elicit a deep sense of embodied transformation. Therapeutic influence was especially evident in music's dichotomous elicitations: Music could simultaneously anchor and propel. Participant openness to music and provision of participant-centered music were associated with optimal immediate and longer-term outcomes. Many studies reported scarce details about the music used and incidental findings of music experienced. Further understanding of participants' idiosyncratic and shared responses to music during drug therapy phases will inform optimal development of flexible music protocols which enhance psychedelic therapy. Music therapists could be involved in the psychedelic therapy research renaissance through assisting with research to optimize music-based protocols used. If psychedelics become approved medicines, music therapists may be involved in offering psychedelic therapy as part of therapeutic teams.

Abstract Title:
Indomethacin and resveratrol as potential treatment adjuncts for SARS-CoV-2/COVID-19.
Abstract:
The ongoing pandemic due to severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2, also known as COVID-19) has led to unprecedented challenges for the global healthcare system. This novel coronavirus disease phenotype ranges from asymptomatic carriage to fulminant cytokine storm with respiratory failure, polyorgan dysfunction, and death. Severe disease is characterized by exuberant inflammation resulting from high circulating cytokines such as interleukin-6 (IL-6) and tumor necrosis factor (TNF). These inflammatory mediators are responsible for the detrimental effects on the immune, hematologic, respiratory, renal, gastrointestinal and other body systems. In addition to inhibition of viral replication, blunting this inflammatory response before overt cytokine storm is important to improve outcomes. Although there are upcoming promising agents such as remdesivir and convalescent plasma, inexpensive, safe, and widely available adjunct treatments to ameliorate disease burden would be welcome. Two potential antiinflammatory agents include indomethacin, which has been shown in experimental models to decrease canine coronavirus (CCoV) levels in dogs and exhibit antiviral activity against several other viruses, and the polyphenol, resveratrol, a potent antioxidant that has shown antiviral activity against several viruses.

Abstract Title:
Herbal treatments for migraine: A systematic review of randomised-controlled studies.
Abstract:
Herbal treatments are often used as a treatment for migraine. Therefore, an evaluation of their safety and efficacy is important. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and Cochrane Collaboration's tool for assessing the risk of bias, a systematic literature review of randomised, controlled human trials assessing the effects of herbal treatments delivered as a single ingredient for the acute or prophylactic treatment of migraine were conducted. Studies were identified through electronic database searches on Medline (Pubmed), Cochrane Library, Scopus, and CINAHL. Nineteen studies were identified examining the effects on migraine of feverfew, butterbur, curcumin, menthol/peppermint oil, coriander, citron, Damask rose, chamomile, and lavender. Overall, findings on the efficacy of feverfew were mixed and there was positive, albeit limited evidence for butterbur. There were positive, preliminary findings on curcumin, citron, and coriander as a prophylactic treatment for migraine, and the use of menthol and chamomile as an acute treatment. However, the risk of bias was high for many studies. The results of this systematic review suggest that several herbal medicines, via their multifactorial physiological influences, present as potential options to enhance the treatment of migraine. However, further high-quality research is essential to examine their efficacy and safety as a treatment for migraine.

Abstract Title:
The Effect of Music Therapy and Aromatherapy with Chamomile-Lavender Essential Oil on the Anxiety of Clinical Nurses: A Randomized and Double-Blind Clinical Trial.
Abstract:
Nurses may be anxious due to critical and emergencies, and anxiety can affect their professional performance. Non-pharmacological interventions, as a safe method, can reduce anxiety. This study aimed to determine the effect of music therapy and aromatherapy with chamomile – lavender essential oil on the anxiety of clinical nurses. This was a randomized, double-blind clinical trial. One hundred twenty nurses from clinical wards of Besat Hospital in Sanandaj, Iran, were selected between 2018 and 2019 by purposeful sampling. The samples were randomly assigned to three groups with different interventions, namely music therapy, both aromatherapy with chamomile-lavender essential oil and music therapy, and aromatherapy with chamomile-lavender essential oil, along with a control group as well. The anxiety of nurses was measured based on the Beck Anxiety Inventory before the intervention and after three work shifts. The data were analyzed using the SPSS v.22 software. One-way ANOVA was used to test the hypotheses. The findings showed that the mean scores of the anxiety of nurses after the intervention in the three groups namely the group for which music therapy was applied, the group for which aromatherapy with chamomile-lavender essential oil was used and the group for which both music therapy and aromatherapy with chamomile-lavender essential oil were applied, were (39.28), (37.82) and (40.03), respectively. Therefore, the obtained mean score of each group was significantly lower than that of the control group (56.08) (p

Abstract Title:
Anti-inflammatory activity of a fixed combination of probiotics and herbal extract in an in vitro model of intestinal inflammation by stimulating Caco-2 cells with LPS- conditioned THP-1 cells medium.
Abstract:
BACKGROUND: Inflammatory bowel disease (IBD) is an inflammatory condition of the gastrointestinal tract, characterized by chronic and relapsing immune system activation, often diagnosed in adolescence, with a rising incidence in pediatric populations. IBD results from altered interactions between gut microbes and the intestinal immune system which induce an aberrant immune response, thus anti-inflammatory or immunosuppressive therapies are generally used. Recent interest has been given to the identification of integrative and complementary approaches that could be able to restore and preserve the intestinal barrier function.METHODS: In this work, we tested the effect of a fixed combination of probiotics and herbal extract (ColikindGocce®, CKG) in an in vitro model of intestinal inflammation. CaCo-2cells stimulated with LPS-conditioned monocytes culture medium was used as a paradigm of intestinal inflammation. The possible effect of CKG in maintaining the homeostasis of the intestinal epithelial barrier was investigated by measurement of the trans- epithelial electrical resistance, the paracellular permeability, and the release of inflammatory cytokines (TNF-α, IL8, and IL10).RESULTS: Results obtained in this work demonstrated that CKG is able to prevent the impairment of intestinal barrier function induced by inflammation, ameliorating the transepithelial electrical resistance and the paracellular permeability of the Caco-2 monolayer; moreover, CKG is able to counteract the increased release of TNF-a and IL-8 induced by inflammatory stimulus, thus reducing the intestinal inflammation.CONCLUSIONS: This work underlines the protective effect of CKG on intestinal barrier, reducing the damages induced by inflammatory stimulus. This suggests CKG as an interesting product in the management of intestinal inflammatory conditions.
