This pilot, exploratory project examined the relationship among the health, work, and social support of university housekeepers. The first objective was to examine the influence of social support on work-related outcomes among university housekeepers. The secondary objective was to examine the influence of social support on physical and psychological health among housekeepers.

However, little is known about its role in mental health outcomes, especially for emerging adults. Utilizing structural equation modeling, we examined the role of family weight teasing (FWT) and parental encouragement to diet in anxiety and depression and explored body weight perception as a moderator within a sample of 292 emerging adults.

To date, there are no studies that have attempted to understand ED use empirically, without arbitrary use of "cut-points." This study was conducted to identify the best-performing, empirically grounded definition of frequent ED use.

Little is understood about the psychological, social, and spiritual factors that protect patients from adverse effects after a physical trauma or their experiences with each factor afterward.
Objective: This systematic review was conducted to investigate and review advancements in research related to risk and resiliency factors experienced by survivors of traumatic musculoskeletal injuries.
We herein present broadly useful, readily available and nonintegral hydroxylamine linkers for the routine solid-phase synthesis of hydroxamic acids. The developed protocols enable the efficient synthesis and release of a wide range of hydroxamic acids from various resins, relying on high control and flexibility with respect to reagents and synthetic processes. A trityl-based hydroxylamine linker was used to synthesize a library of peptide hydroxamic acids.

In this paper, we present the synthesis and biological evaluation of a series of dihydropyrano[2,3-c]pyrazole derivatives as a novel family of PPARγ partial agonists. Two analogues were found to display high affinity for PPARγ with potencies in the micro molar range.

Using actor-partner interdependence models, we examined how turning to one's spouse and one's friend was linked to changes in both spouses' marital satisfaction and conflict 1 year later. We also investigated whether satisfaction and conflict predicted change in MW for older spouses.

Accordingly, the current study used actor-partner interdependence models to examine the relationship between a spiritual cognition (i.e.

A variety of alkynes were efficiently immobilized on a range of polymeric supports by Cu(I)-mediated azide-alkyne cycloadditions. Supported triazoles showed excellent compatibility with subsequent peptide chemistry.
View Article and Find Full Text PDFA huge unleashed potential lies hidden in the large and diverse pool of encoded and particularly nonencoded chiral alpha-, beta-, and gamma-amino acids available today. Although these have been extensively exploited in peptide science, the community of organic chemistry has only used this source of diversity in a quite focused and targeted manner. The properties and behavior of peptides as functional molecules in biology are well documented and based on the ability of peptides to adapt a range of discrete conformers at a minimal entropic penalty and therefore ideally fitting their endogenous targets.

The modular design allows a short and efficient synthesis of an array of aryl-ferrocenyl derivatives carrying the donating bis(dicyclohexyl)phosphino moiety. These new ligands have successfully been applied in the palladium-catalyzed Suzuki cross-coupling of activated as well as nonactivated aryl chlorides at room temperature.

The strategy is short and involves a new synthetic approach to aryl-ferrocenyl compounds via a Suzuki cross-coupling procedure. The modular design can easily give access to variety of chiral mono- and bidentate ligands.

Much work has been devoted to elucidating effective catalysts for this process, but hitherto only one effective and highly stereoselective process has been available. Herein we present a novel catalytic system for the asymmetric hydrosilylation of aromatic alkenes, giving the products in high yields and with the highest enantioselectivity (up to 99% ee) ever observed for this reaction.
View Article and Find Full Text PDFThe selectivity-determining step in enantioselective copper-catalyzed cyclopropanation with diazo compounds has been studied by experimental and computational methods. The addition of the very reactive metallacarbene intermediate in an early transition state to the substrate alkene is concerted but strongly asynchronous, with substantial cationic character on one alkene carbon in the neighborhood of the transition state. Evidence from isotope effects and Hammett studies supports the nature of the transition state.
