Asymmetric palladaelectro-catalyzed C-H olefinations were achieved through the synergistic cooperation with transient directing groups. The electrochemical, atroposelective C-H activations were realized with high position-, diastereo-, and enantio-control under mild reaction conditions to obtain highly enantiomerically-enriched biaryls and fluorinated N-C axially chiral scaffolds. Our strategy provided expedient access to, among others, novel chiral BINOLs, dicarboxylic acids and helicenes of value to asymmetric catalysis. Mechanistic studies by experiment and computation provided key insights into the catalyst’s mode of action. © 2020 WILEY-VCH Verlag GmbH & Co.

This project utilized a national study with a convenience selection of acute care agencies to examine the relationship between organizational and unit culture, EBP, and self-efficacy in frontline nurses. METHODS This national study used descriptive correlational methodology to describe differences in EBP and self-efficacy among RNs. Selleck Fluvastatin The sample included 245 frontline RNs employed in acute care settings. To measure the study variables, the Nursing Evidence-Based Practice Survey (Titler, Hill, Matthews, & Reed, 1999)  and the Evidence-Based Nursing Practice Self-Efficacy Scale were used (Tucker, Olson, & Frusti, 2009). Each instrument was delivered via the Qualtrics online platform. RESULTS The correlation of bivariate interval level variables was analyzed using Pearson’s r. The correlation between EBP and self-efficacy was strongly correlated r(170) = .537, p = .01. Sections within the Nursing Evidence-Based Practice Survey were calculated and found to be significant (unit culture r = .241, p = .01; organizational culture r = .570, p = .01; knowledge, skills, attitude r = .538, p = .01). LINKING EVIDENCE TO ACTION Several implications exist for education, staff development, and nursing management. Nursing school programs incorporate EBP into the curriculum so that nurses have a foundation for EBP. However, staff development professionals in clinical settings must continue to build on the nurses’ knowledge and skill, thus increasing self-confidence for EBP. Nursing management can provide the resources for staffing models and policies to reinforce the value of EBP and positive patient outcomes. This combination provides frontline staff with EBP participation and increased self-efficacy in its usage. © 2020 Sigma Theta Tau International.The new allele HLA-B*13109 differs from HLA-B*13010101 by one nucleotide substitution in Exon 4.

Combining synthetic scaffolds with biomimetic fibrin does direct both exogenous and endogenous stem cell differentiation, addressing needs for reliable tissue engineering. However, lack of immediate vasculature within implantable grafts remains critical for its sustenance and integration. Multipotency, high proliferation potential, ability to release multiple growth factors (GFs), and autologous availability highlight the use of human adipose derived mesenchymal stem cells (hADMSCs) in tissue-engineered dermal grafts (TEDG) construction. However, hADMSCs’ insufficiency to independently establish angiogenesis within tissue constructs demands improvement of stem cell application for dermal graft survival. Approaches to harness microenvironmentally sensitive paracrine interactions could improve the angiogenic efficiency of hADMSCs within TEDG. This study conceptualized a fibrin-based niche, to direct hADMSCs toward a nonfibrotic fibroblast commitment and incorporation of bioengineered hADMSCs, specifically releasing potent angiogenic factors within TEDG. Coexistence of tuned fibroblast and endothelial lineage committed cells contributed to well-regulated extracellular matrix formation and prevascularization. Adequate cell proliferation; sustained transient release of angiogenic GFs till 20 days; directed dermal, endothelial, fibroblast, and vascular smooth muscle cell differentiation; and favored elastin and collagen deposition were achieved in vitro. In conclusion, specific niche composition and employment of bioengineered hADMSCs favor implantable TEDG construction. © 2020 Wiley Periodicals, Inc.INTRODUCTION The anterior cruciate ligament (ACL) prevents the anterior translocation and medial rotation of the tibia against the femur. It is typically composed of dense regular connective tissue (DRCT), small amount of loose connective tissue, little vasculature, and few nerve endings. The objective of the current study was to evaluate the details of histological changes in ACLs of patients with clinically diagnosed osteoarthritis (OA). MATERIALS AND METHODS The ACLs of six patients undergoing total knee replacement because of OA (OA group) were compared with 16 normal ACLs from cadavers (control). The ACLs were analyzed for tissue composition and number of blood vessels across the full length and thickness of the ligament. Percentages for areas of DRCT, fibrocartilage, degenerative tissue, and vasculature were calculated. Tissue composition and relative number of blood vessels were compared between groups. RESULTS The proportion of DRCT to non-DRCT was significantly smaller in the OA group than the control group (p  less then  .001); non-DRCT included degenerative connective tissue and fibrocartilage. The number of blood vessels to area was greater in the OA group than the control group (p = .002). Six of control (37.5%) and five of OA ACLs (83%) showed areas of calcification. CONCLUSIONS These results indicate that inflammatory processes contributing to OA in the knee cause changes in the composition of the ACL that lead to destruction of collagen bundles, increased vascularization, calcification, and formation of fibrocartilage-like tissue inside the ligament. These changes make ligament-retaining total knee arthroplasty a less beneficial option for knee repair. © 2020 Wiley Periodicals, Inc.
