  • The emergence of multidrug-resistant microorganisms, as well as fungal infectious diseases that further threaten health, especially in immunodeficient populations, is a major global problem. The development of new antifungal agents in clinical trials is inferior to the incidence of drug resistance, and the available antifungal agents are restricted. Their mechanisms aim at certain characteristics of the fungus in order to avoid biological similarities with the host. Synthesis of the cell wall and ergosterol are mainly targeted in clinical use. The need for new approaches to antifungal therapeutic agents or development alternatives has increased. This review explores new perspectives on mechanisms to effectively combat fungal infections and effective antifungal activity. The clinical drug have a common feature that ultimately causes caspase-dependent cell death. The drugs-induced cell death pathway is associated with mitochondrial dysfunction, including mitochondrial membrane depolarization and cytochrome c release. This mechanism of action also reveals antimicrobial peptides, the primary effector molecules of innate systems, to highlight new alternatives. Furthermore, drug combination therapy is suggested as another strategy to combat fungal infection. The proposal for a new approach to antifungal agents is not only important from a basic scientific point of view, but will also assist in the selection of molecules for combination therapy.

  • When medicine is unable to cure, and the end becomes imminent, or when the patient is tired of the side effects associated with chronic use of drugs, the search for alternative and new ways of healing is begun. Coincidentally, sometimes the alternative is the origin, as is the case for traditional Arab medicine and traditional American Indian healing. Traditional healing is the first healing that all people have used for 200,000 years, since the beginning of Homo sapiens. The sources and elements of traditional Arab medicine have been examined in books and by consulting with traditional Arab healers. Arabic medicine is a career combining both elements of science and philosophy based on religion and traditions, and includes a diversity of healing approaches: spiritual, physical, and using natural products. These approaches are discussed with emphasis on wet cupping (Alhijamah), a practice that is undergoing a revival nowadays in Arab countries. American Indian healing is a career based on religion, tradition, an innate healing gift and extensive training, both in a medical school setting and as an apprentice. Arabic healing approaches are compared to American Indian healing approaches.

  • This paper presents an analysis of the Developmental Approaches in Science, Health and Technology (DASH) program, a K-6 curriculum developed by the Curriculum Research & Development Group (CRDG) at the University of Hawaii employing the curriculum analysis framework created by Posner. Using this framework the analyst found that the DASH design is based on the research on learning, teaching, and assessment now driving efforts to reform science education at the elementary level. DASH embraces the constructivist idea that learning is a personal and social process and the recapitulation model that new concepts are built out of theories previously learned. DASH provides an understandable, exciting, and memorable experience in the operations of science, health, and technology, and develops their capacity to use the skills and knowledge of science, health, and technology both in and outside school. A number of studies of DASH have examined its functionality, effectiveness of pedagogy and what students learn. The innovative nature of DASH necessitated a multidimensional assessment that included both quantitative and qualitative research techniques. Ongoing development of the DASH program in the research setting of a university laboratory school permits ever deeper connections with emerging curriculum theory and curriculum practice, and allows new linkages as ideas are tested in research classrooms.
