in this study we report the rock magnetic properties of surface soil samples and their spatialvariability from the northernmost district of kerala to understand pedogenic processes and soil erosion. themagnetic signal is mainly from fine grained pedogenic magnetite as other sources like anthropogenic andlithogenic magnetite, bacterial magnetite and greigite are absent. the surface soil samples ...

conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. in the recovery system, super-critical an co2 is employed as the working fluid operating in a brayton cycle. low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes the hot gases lea...

anxiety disorders are a group of psychiatric disorders which can have negative effects on the human life. children and adults can have anxiety disorders and these disorders can lead to secondary problems such as cognitive, perceptual, emotional and behavioral problems. for treatment of anxiety, the practitioners and psychologists can apply psychotherapy approaches such as: cognitive therapy, ge...

the term “system” is defined as «elements standing interaction». this implies that a change in any given element should bring about changes in other elements of the system and thus may be used to identify the boundaries of a system. a system can be a machine, a man, or a community. each of these may be part of a greater system (super system) or include several smaller systems (subsystems). syst...

background and aims: the novel approaches in influenza vaccination have targeted more conserved viral proteins such as nucleoprotein (np) to provide cross protection against all serotypes of influenza a viruses. influenza specific cytotoxic t lymphocytes (ctl) are able to lyse influenza-infected cells by recognition of np, the major target molecule in virus for ctl responses. on the other hand,...

background: proliferating cell nuclear antigen (pcna) is a nuclear protein synthesized in the late g1 and s-phase of the cell cycle. detection of this protein represents a useful marker of the proliferation status of lesions. this study has been carried out to evaluate the cell proliferation rate in oral lichen planus (olp) and comparison between plaque and erosive lichen planus, which indicate...

Polymorphism in pathogen antigens presents a complex challenge for vaccine design. A prime example is the N-terminal block 2 region of the Plasmodium falciparum merozoite surface protein 1 (MSP1), to which allele-specific antibodies have been associated with protection from malaria. In a Zambian population studied here, 49 of 91 alleles sampled were of the K1-like type (the most common of three...

For efficient development of an immune response, T lymphocytes require long-lasting calcium influx through calcium release-activated calcium (CRAC) channels and the formation of a stable immunological synapse (IS) with the antigen-presenting cell (APC). Recent RNAi screens have identified Stim and Orai in Drosophila cells, and their corresponding mammalian homologs STIM1 and Orai1 in T cells, a...

Understanding how nanoparticles may affect immune responses is an essential prerequisite to developing novel clinical applications. To investigate nanoparticle-dependent outcomes on immune responses, dendritic cells (DCs) were treated with model biomedical poly(vinylalcohol)-coated super-paramagnetic iron oxide nanoparticles (PVA-SPIONs). PVA-SPIONs uptake by human monocyte-derived DCs (MDDCs) ...
