nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. for studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...
Mathematical models are becoming increasingly useful in studying the dynamics of infectious diseases, from within-host to between-host scales. With HIV and influenza as case studies, I will demonstrate how modeling can provide great insights into complex phenomena of these diseases. First, I will present a within-host model that can help address some of the issues related to the HIV-1 treatment...
This review summarizes recent evidence from knock-out mice on the role of reactive oxygen intermediates and reactive nitrogen intermediates (RNI) in mammalian immunity. Reflections on redundancy in immunity help explain an apparent paradox: the phagocyte oxidase and inducible nitric oxide synthase are each nonredundant, and yet also mutually redundant, in host defense. In combination, the contr...
Numerous loci in host organisms are involved in parasite recognition, such as major histocompatibility complex (MHC) genes in vertebrates or genes involved in gene-for-gene (GFG) relationships in plants. Diversity is commonly observed at such loci and at corresponding loci encoding antigenic molecules in parasites. Multilocus theoretical models of host-parasite coevolution predict that polymorp...
Malaria and trypanosomiasis are vector-borne protozoal diseases which disproportionately affect the poor. Both give rise to immense human suffering; malaria exerts its effect directly on human health, while trypanosomiasis causes damage largely though its effect on the health and productivity of the livestock on which so many poor people depend. These diseases both have multifaceted and poorly ...
While disease-induced extinction is generally considered rare, a number of recently emerging infectious diseases with load-dependent pathology have led to extinction in wildlife populations. Transmission is a critical factor affecting disease-induced extinction, but the relative importance of transmission compared to load-dependent host resistance and tolerance is currently unknown. Using a com...
confocal laser scanning microscopy (clsm) is a revolutionary advance in the field of light microscopy which, in recent years, has been used on interaction studies between host and pathogen. this study carried out on the flag leaves of the susceptible spring wheat cultivar (triticum aestivum l.) known as thatcher and its near isogenic line with the yr-18 adult-plant resistance gene to stripe rus...
To meet the challenges of increasing antimicrobial resistance, the infectious disease community needs innovative therapeutics. Precision medicine and immunotherapies are transforming cancer therapeutics by targeting the regulatory signaling pathways that are involved not only in malignancies but also in the metabolic and immunologic function of the tumor microenvironment. Infectious diseases ta...
