Hox and ParaHox genes constitute two families of developmental regulators that pattern the Anterior-Posterior body axis in all bilaterians. The members of these two groups of genes are usually arranged in genomic clusters and work in a coordinated fashion, both in space and in time. While the mechanistic aspects of their action are relatively well known, it is still unclear how these systems evolved. For instance, we still need a proper model of how the Hox and ParaHox clusters were assembled over time. This problem is due to the shortage of information on gene complements for many taxa （mainly basal metazoans） and the lack of a consensus phylogenetic model of animal relationships to which we can relate our new findings. Recently, several studies have shown that the Acoelomorpha most probably represent the first offshoot of the Bilateria. This finding has prompted us, and others, to study the Hox and ParaHox complements in these animals, as well as their activity during development. In this review, we analyze how the current knowledge of Hox and ParaHox genes in the Acoelomorpha is shaping our view of bilaterian evolution.

Chronic kidney disease is currently a major public health problem around the world. Although hemodialysis increases survival of patients with end-stage renal disease, kidney transplantation remains the only potentially curative treatment. However, transplantation as a therapeutic option is limited by availability of suitable donor organs. This situation highlights the urgent need to find new and potentially inexhaustible sources of transplantable organs. Perfusion decellularizarion of whole organs is a novel approach to organ engineering and regeneration. In the present research, we used a continuous perfusion decellularization protocol to eliminate cellular componet of kidney and evaluated residual scaffold components after decellularizarion process by proteomics analysis. Our proteomic data show that this protocol results in incomplete removal of cellular proteins. However, unlike other authors, we assume that proteins retained within decellularized kidney scaffold could be the basis for specific homing and celular differentation in the recellularization process.

The liver plays a crucial role in maintaining whole-body metabolic homeostasis and harbors a distinct immune environment(Robinson et al.,2016).However,during the aging process,the liver undergoes structural and functional changes that can disrupt the delicate balance between the immune system and liver *** age-related alterations can lead to increased susceptibility to metabolic diseases,including non-alcoholic fatty liver disease(NAFLD),and impairments in immune cell regulation and tissue repair(Albillos et al.,2022;Anstee et al.,2019).

2-nitrobenzofuran is studied as dienophile in polar thermal Diels-Alder reactions with normal electron demand using several structurally different dienes. A very strong electron-acceptor group, such as nitro group, enhances the dienophilic character of these heterocyclic compounds and owing to the fact that this substituent is easily extruded under thermal conditions this reaction sequence becomes a simple method of organic compound＇s families with heteroatom rings preparation. Part of this work is specifically concerned with theoretical studies. The global and local electrophilicity and nucleophilicity indexes were calculated for the dienophile and dienes used in this work. A concise synthesis of dibenzofurans has been development via cycloaddition reactions.
