Evolution Of Immunity

While invertebrates lack the machinery necessary for ‘acquired immunity’, there is increasing empirical evidence that exposure to low levels of disease may ‘prime’ an invertebrate's immune response, increasing its defence to subsequent exposure. Despite this increasing empirical data, there has been little theoretical attention paid to immune priming. Here, we investigate the evolution of immune priming, focusing on the role of the unique feedbacks generated by a newly developed susceptible–primed–infected epidemiological model. Contrasting our results with previous models on the evolution of acquired immunity, we highlight that there are important implications to the evolution of immunity through priming owing to these different epidemiological feedbacks. In particular, we find that in contrast to acquired immunity, priming is strongly selected for at high as well as intermediate pathogen virulence. We also find that priming may be greatest at either intermediate or high host lifespans depending on the severity of disease. Furthermore, hosts faced with more severe pathogens are more likely to evolve diversity in priming. Finally, we show when the evolution of priming leads to the exclusion of the pathogens or hosts experiencing population cycles. Overall the model acts as a baseline for understanding the evolution of priming in host–pathogen systems.

The aim of the present docking study was to explore the putative role of boronic moieties in molecules interacting on the binding site of the SARS-CoV-2 main protease. The methodology was based on the conventional docking procedure by means of AutoDock software by assaying boron-free and boron-containing compounds on the recent reported crystal structure of SARS-CoV-2 main protease (PDB code: 6LU7). The most of tested compounds share contact with key residues and poses on the cleavage pocket. Those compounds with a boron atom in its structure often were estimated with higher affinity than boron-free analogues. Interactions and affinity of boron-containing peptidomimetics on the binding site let us to propose the potent inhibition of these compounds on targeted protease. These advances may be relevant for drug designing, but also to suggest the testing of available boron-containing drugs in patients with severe symptoms of COVID19 infection.

Informal Setting

This article attempts to focus on Islamic education in the informal setting, its correspondence with human resource development and the role of this development to create a sound and balanced environment in society with moral and spiritual values. Firstly, the paper addresses education and its function in general and then education from Islamic perspective. Secondly, it discusses the character of informal Islamic education, the role players of the field of informal Islamic education, their status as teachers, the role of a teacher, the competencies of a teacher, and teacher - learner relationship in the light of Islamic culture and heritage. Finally, a proposal on the specific subject of Informal Islamic education and the strategies of imparting it are presented in the article.   doi: 10.3329/iiucs.v3i0.2667   IIUC STUDIES Vol. - 3, December 2006 (p 83-92)
