In recent years, the chemistry of metal-coordination polymers has been advanced due to their diverse topologies and potential applications in smart optoelectronic, magnetic, microporous and biomimetic materials with specific structures, properties, and reactivities. Metal carboxylates have emerged as a large family of open framework materials. Recently, metal carboxylate chemistry has enhanced because of the increasing importance of hybrid inorganic-organic compounds with potential applications in separation, catalysis, and gas storage. So far, research on coordination polymers has considerably been concentrated on incorporation of s-, d-, and even f-block metal ions as coordination centers. As a heavy p-block metal ion, lead(II), with its large radius, flexible coordination environment, and variable stereo-chemical activity, is suitable for formation of unusual network topologies with interesting properties. This review provides an overview of all lead(II) carboxylate supramolecular compounds reported since 1990 and an investigation of their coordination modes, properties and structures. The variety of coordination modes of carboxylate groups increase the strength and stability of the resulting architectures. These modes include (η1), (μ2-η1:η1), (η2), (μ2-η2), (μ3-η1:η2), (μ3-η1:η2), (μ2-η2:η1), (μ3-η1:η2:η1) and (μ4-η2:η2) that have created multiplicity polymeric structures with different dimensions. In this study it was found that carboxylate groups in many of lead(II) coordination polymers form more than a single type of coordination mode and among all of these modes maximum number belonged to chelating (η2) mode. © 2011 Elsevier B.V.

Insulin enhances the compliance of conduit arteries, relaxes resistance arterioles to increase tissue blood flow, and dilates precapillary arterioles to expand muscle microvascular blood volume. These actions are impaired in the insulin resistant states. Exercise ameliorates endothelial dysfunction and improves insulin responses in insulin resistant patients, but the precise underlying mechanisms remain unclear. The microvasculature critically regulates insulin action in muscle by modulating insulin delivery to the capillaries nurturing the myocytes and trans-endothelial insulin transport. Recent data suggest that exercise may exert its insulin-sensitizing effect via recruiting muscle microvasculature to increase insulin delivery to and action in muscle. The current review focuses on how the interplay among exercise, insulin action, and the vasculature contributes to exercise-mediated insulin sensitization in muscle. © 2015 Elsevier Ltd. Source

Recent empirical research has shown that links between groups reinforce individuals within groups to adopt cooperative behaviour. Moreover, links between networks may induce cascading failures, competitive percolation, or contribute to efficient transportation. Here we show that there in fact exists an intermediate fraction of links between groups that is optimal for the evolution of cooperation in the prisoner's dilemma game. We consider individual groups with regular, random, and scale-free topology, and study their different combinations to reveal that an intermediate interdependence optimally facilitates the spreading of cooperative behaviour between groups. Excessive between-group links simply unify the two groups and make them act as one, while too rare between-group links preclude a useful information flow between the two groups. Interestingly, we find that between-group links are more likely to connect two cooperators than in-group links, thus supporting the conclusion that they are of paramount importance. © 2013 Macmillan Publishers Limited.

The invention discloses a method for producing 30-halogenated betulinic acid. Betulin is used as a raw material and selectively oxidized and halogenated to generate 30-betulinic acid, and the selected oxidation and halogenation agent has high selectivity and does not affect C-3 hydroxyl or carbon-carbon double bonds. Oxidation and halogenation are completed in one step, so the process route is short, the treatment method is simple, and the product is purified easily.
