Habits as Building Blocks for the Resilience of Vulnerable Populations: Two Positive Deviance Case Studies From the U.S.-Mexico Border Region.

In this article, we describe habits that lead to resilience. We summarize empirical findings of two projects implemented with people living in the U.S.

Using a Positive Deviance Approach to Influence the Culture of Patient Safety Related to Infection Prevention.

Background: Health care-associated infections (HAIs) are a socio-technical problem. We evaluated the impact of a social change intervention on health care personnel (HCP), called "positive deviance" (PD), on patient safety culture related to infection prevention among HCP.

Methods: This observational study was done in 6 medical wards at an 800-bed public academic hospital in the United States.

PGA1-induced apoptosis involves specific activation of H-Ras and N-Ras in cellular endomembranes.

The cyclopentenone prostaglandin A1 (PGA1) is an inducer of cell death in cancer cells. However, the mechanism that initiates this cytotoxic response remains elusive. Here we report that PGA1 triggers apoptosis by a process that entails the specific activation of H- and N-Ras isoforms, leading to caspase activation.

Design of BODIPY Dyes as Photosensitisers in Multicomponent Catalyst Systems for Light-Driven Hydrogen Production.

A study of visible-light-driven hydrogen production using a multicomponent system consisting of different boron dipyrromethene (BODIPY) dyes, triethylamine and [{Pd(PPh3)Cl2}2] from THF/water mixtures is presented. A trio of meso-mesityl BODIPY dyes display the best activities and long-term stabilities of more than ten days with the 2,6-diiodo derivative showing the best performance.

Highly selective visible light-induced Ti-O bond splitting in an ansa-titanocene dihydroxido complex.

Irradiation of a substituted ansa-titanocene(IV) dihydroxido complex with visible light induces Ti-O bond dissociation. In contrast to previous studies on structurally similar unbridged complexes, no side reactions are observed and formation of the Ti(III) species is highly selective. The formation of OH radicals was proved using a biradicaloid species.
