TL;DR: These nanoparticle networks have several advantages over conventional bulk gels for controlling the release of high molecular weight biomolecules and release of low molecular weight dextrans from the PNIPAM-co-AA network showed a temperature-independent release profile.

TL;DR: A family attachment network model of military families during deployment and reintegration that is grounded in attachment theory and family systems theory is described, which will inform future research and intervention efforts with service members and their families.
Abstract: Deployment separation constitutes a significant stressor for U.S. military men and women and their families. Many military personnel return home struggling with physical and/or psychological injuries that challenge their ability to reintegrate and contribute to marital problems, family dysfunction, and emotional or behavioral disturbance in spouses and children. Yet research examining the psychological health and functioning of military families is scarce and rarely driven by developmental theory. The primary purpose of this theoretical paper is to describe a family attachment network model of military families during deployment and reintegration that is grounded in attachment theory and family systems theory. This integrative perspective provides a solid empirical foundation and a comprehensive account of individual and family risk and resilience during military-related separations and reunions. The proposed family attachment network model will inform future research and intervention efforts with service members and their families.

TL;DR: In this article, the authors refine and extend the study of entrepreneurial dispositions by linking three classic hallmarks of the entrepreneur (achievement motivation, risk-taking propensity, and preference for innovation) to the goal orientations of United States and Russian entrepreneurs.
Abstract: We refine and extend the study of entrepreneurial dispositions by linking three classic hallmarks of the entrepreneur—achievement motivation, risk–taking propensity, and preference for innovation—to the goal orientations of United States and Russian entrepreneurs. The results suggest that entrepreneurial dispositions vary according to culture and the entrepreneur's primary goal for the venture. The results have important implications for theoretical development linking dispositions and entrepreneurial behavior in different settings and for entrepreneurial education and government policy.

TL;DR: Findings suggest that cardiovascular responses elicited during imagined exercise involve central activation of insular and anterior cingulate cortexes, independent of muscle afferent feedback; these structures appear to have key roles in the central modulation of cardiovascular responses.
Abstract: The purpose was to compare patterns of brain activation during imagined handgrip exercise and identify cerebral cortical structures participating in “central” cardiovascular regulation. Subjects sc...

TL;DR: The new route involved first preparing poly(N-isopropylacrylamide) (PNIPAM)-allylamine copolymer microgels and a spiropyran photochrome (SP) bearing a carboxylic acid group coupled to the microgel via an amide bond.
Abstract: Microgels with photo-, thermally, and pH-responsive properties in aqueous suspension have been synthesized and characterized using dynamic light scattering and UV-visible spectroscopy. The new route involved first preparing poly(N-isopropylacrylamide) (PNIPAM)-allylamine copolymer microgels and a spiropyran photochrome (SP) bearing a carboxylic acid group. Then the functionalized spiropyran was coupled to the microgel via an amide bond. The dark-equilibrated gel particles feature spiropyran molecules in the polar, merocyanine form. After irradiation of visible light, the particle size becomes smaller because spiropyran changes to the relatively nonpolar, closed spiro form. The PNIPAM-SP microgels undergo a volume phase transition in water from a swollen state to a collapsed state with increasing temperature under all light conditions. However, the transition temperature range of the PNIPAM-SP is much broader than that for the PNIPAM without SP. The PNIPAM-SP microgels are monodisperse and self-assemble into a crystalline lattice while in suspension. The UV-visible spectra of an aqueous suspension of PNIPAM-SP microgel in the dark-adapted, merocyanine form showed both an absorption peak around 512 nm due to the merocyanine (giving a reddish color to the suspension) and two sharp peaks from Bragg diffraction of colloidal crystallites. Upon visible irradiation, the 512-nm band bleached significantly due to spiropyran photoisomerization. The spiropyran photoisomerization and accompanying color changes of the suspension were reversible upon alternating dark, UV, and visible light irradiation. Due to the residues of amine groups, the swelling capability of PNIPAM-SP microgels reduces as the pH value is changed from 7 to 10.
