Morphology alterations of skin and subcutaneous fat at NIR laser irradiation combined with delivery of encapsulated indocyanine green
The goal of this study is to quantify the impact of the in vivo photochemical treatment of rats with obesity using indocyanine green (ICG) dissolved in saline or dispersed in an encapsulated form at NIR laser irradiation, which was monitored by tissue sampling and histochemistry. The subcutaneous injection of the ICG solution or ICG encapsulated into polyelectrolyte microcapsules, followed by diode laser irradiation (808 nm, 8 W / cm 2 , 1 min), resulted in substantial differences in lipolysis of subcutaneous fat. Most of the morphology alterations occurred in response to the laser irradiation if a free-ICG solution had been injected. In such conditions, membrane disruption, stretching, and even delamination in some cases were observed for a number of cells. The encapsulated ICG aroused similar morphology changes but with weakly expressed adipocyte destruction under the laser irradiation. The Cochran Q test rendered the difference between the treatment alternatives statistically significant. By this means, laser treatment using the encapsulated form of ICG seems more promising and could be used for safe layerwise laser treatment of obesity and cellulit

Claudins in lung diseases
Tight junctions are the most apically localized part of the epithelial junctional complex. They regulate the permeability and polarity of cell layers and create compartments in cell membranes. Claudins are structural molecules of tight junctions. There are 27 claudins known, and expression of different claudins is responsible for changes in the electrolyte and solute permeability in cells layers. Studies have shown that claudins and tight junctions also protect multicellular organisms from infections and that some infectious agents may use claudins as targets to invade and weaken the host's defense. In neoplastic diseases, claudin expression may be up- or downregulated. Since their expression is associated with specific tumor types or with specific locations of tumors to a certain degree, they can, in a restricted sense, also be used as tumor markers. However, the regulation of claudin expression is complex involving growth factors and integrins, protein kinases, proto-oncogens and transcription factors. In this review, the significance of claudins is discussed in lung disease and development

An integrated genetic map of the pearl locus of mouse chromosome 13.
We have used a Mus domesticus/spretus congenic animal and two interspecific backcross panels to map genetically 30 sequence-tagged sites (STSs) and 13 genes to the vicinity of the pearl locus on mouse chromosome 13. The STSs defining the mapped region are from D13Mit9 to D13Mit37, spanning 10.6 cM. Genes mapped to this region include Versican (Cspg2), GTPase activating protein (Rasa), dihydrofolate reductase (Dhfr), arylsulfatase (As-1), thrombin receptor (Cf2r), hexosaminidase b(Hexb), 3-hydroxy-3-methylglutaryl coenzyme A reductase (Hmgcr), microtubule associated protein 5/1b (Mtap5), phosphodiesterase (Pde), phosphatidylinositol 3' kinase (Pik3rl), rat integrin a1-subunit (Itga1), collagen receptor a2-subunit (Itga2), and 5-hydroxytryptamine 1a receptor (Htr1a). This high resolution genetic map of the pearl region of chromosome 13 establishes the order of multiple markers, including genes whose human homologs are located within a limited region of human chromosome 5, with respect to the phenotypic anchor marker pearl
