Pentacene is one of the most versatile organic semiconductors, yet the synthetic acess to pentacene skeleton is quite limited. We hereby report a template-directed approach to pentacene derivatives. In the retrosynthesis, the acene skeleton is viewed as a laddered double strand polyene instead of the more intuitive linearly fused hexagons. Based on this vision, the template strand of polyene is constructed with Wittig olefination, whereas the second strand is accomplished with Knoevenagel condensation to produce pentacene and tetracene derivatives...

BACKGROUND: Indoleamine 2, 3-dioxygenase (IDO) is an immunomodulatory molecule that has been implicated in several biological processes. Although IDO has been linked with some renal diseases, its role in renal fibrosis is still unclear. Because IDO may be modulated by TGF-β1, a potent fibrogenic molecule, we hypothesized that IDO could be involved in renal fibrosis, especially acting in the TGF-β1-induced tubular epithelial-mesenchymal transition (EMT). We analyzed the IDO expression and activity in a model of renal fibrogenesis, and the effect of the IDO inhibitor 1-methyl-tryptophan (MT) on TGF-β1-induced EMT using tubular cell culture...

BACKGROUND: Saving groups are increasingly being used to save in many developing countries. However, there is limited literature about how they can be exploited to improve maternal and newborn health. OBJECTIVES: This paper describes saving practices, factors that encourage and constrain saving with saving groups, and lessons learnt while supporting communities to save through saving groups. METHODS: This qualitative study was done in three districts in Eastern Uganda...

Monolayer contact doping (MLCD) is a modification of the monolayer doping (MLD) technique that involves monolayer formation of a dopant-containing adsorbate on a source substrate. This source substrate is subsequently brought into contact with the target substrate, upon which the dopant is driven into the target substrate by thermal annealing. Here, we report a modified MLCD process, in which we replace the commonly used Si source substrate by a thermally oxidized substrate with a 100 nm thick silicon oxide layer, functionalized with a monolayer of a dopant-containing silane...

STUDY OBJECTIVE: To duplicate the steps of conventional multiport laparoscopic radical hysterectomy by 3 other minimal access modalities: robotic radical hysterectomy, laparoendoscopic single-site surgery (LESS), and orifice-assisted small-incision surgery (OASIS). DESIGN: Institutional Review Board approval was obtained. Between January 2009 and December 2012, the charts of the patients who had undergone radical hysterectomy by these 4 minimal access modalities were analyzed...

REVIEW
M Geiger, K Deloose, J Callaert, M Bosiers
Surgical endarterectomy has been considered the prefered technique for treating the common femoral artery (CFA). Although favorable endovascular treatment results of the CFA have recently become available, losing the groin area as an important acess site is still the major concern for this technique to become the golden standart. Nevertheless, the endovascular approach has shown, through several studies, including our experience, the capacity to establish itself as a complementery treatment for the modern vascular surgeon...

Many patients with rotator cuff tears have questions for their surgeons regarding the surgical procedure, perioperative management, restrictions, therapy, and ability to work after a rotator cuff repair. The purpose of our study was to determine common clinical practices among experts regarding rotator cuff repair and to assist them in counseling patients. We surveyed 372 members of the American Shoulder and Elbow Surgeons (ASES) and the Association of Clinical Elbow and Shoulder Surgeons (ACESS); 111 members (29...

BACKGROUND: Stem cells located in the centre of the shoot apical meristem are required for the repetitive formation of new organs such as leaves, branches and flowers. In Arabidopsis thaliana, the ZWILLE/PINHEAD/AGO10 (ZLL) gene encodes a member of the ARGONAUTE (AGO) protein family and is required to maintain shoot meristem stem cells during embryogenesis. In the Landsberg erecta (Ler) acession, ZLL is essential for stem cell maintenance, whereas in the Columbia (Col) accession its requirement appears masked by genetic modifiers...

Physical spaces need to be adjusted to suit the changes of a physical, cognitive and emotional order occasioned by the natural aging of people. Ergonomics of the built environment contributes to improving the interaction of the user and physical environment, with a view to their comfort and safety. By thinking through the influence that environments have on the quality of life of the elderly, this article presents an assessment of accessibility in private units--bedrooms and bathrooms--of a Long-Stay Institution for the Elderly (ILPI in Portuguese) in Portugal...

Human bocavirus (HBoV) is a recently discovered parvovirus, which is suspected to be an etiologic agent of respiratory disease and gastrointestinal disease in human. In the present study, we screened 941 nasopharyngeal aspirates collected from hospitalized children with lower respiratory tract infections from October 9, 2007 to March 20, 2009 in the Children's Hospital of Hubei Province. Our results showed that 33 of 941 samples (3.51%) were detected positive for HBoV. To obtain a full-length HBoV clone, three segments which covered the nearly full-length genome were amplified by PCR from HBoV positive samples separately and cloned into pBluescript SK II vector, and the resulting plasmid was designated as pWHL-1 (GenBank Acession No...

OBJECTIVES: To compare the safety and efficacy of radial artery access versus femoral artery access for percutaneous coronary intervention in acute myocardial infarction population. METHODS: From June 2004 to December 2006, 446 patients with acute myocardial infarction treated with percutaneous stenting were reviewed retrospectively. The radial artery approach was used in 242 patients, and the femoral artery approach in 204 patients. The success of the procedure, procedure duration, X-ray exposition, volume of contrast, incidence of major adverse cardiac events and complications were compared between the radial artery and femoral artery approach...

OBJECTIVE: The purpose of this study was to determine the yield of open access endoscopy in a third level Mexican hospital. BACKGROUND DATA: Open access endoscopy is common in United States of America and Europe (endoscopy is performed without prior specialist consultation). In Mexico this system hasn't become popular yet. The usefulness of open access endoscopy has been questioned. Some indications for upper gastrointestinal endoscopy (UGE) aren't included in the guidelines for appropriate use of endoscopy...

Acylsugars present in Lycopersicon pennellii are responsible for the high levels of pest resistance often found in this wild tomato taxon. We investigated the inheritance of acylsugar contents in segregating populations of the interspecific tomato cross L. esculentum x L. pennellii and estimated correlations between leaflet acylsugar contents and the levels of mite repellence. Acylsugar contents were quantified with the Sommogy-Nelson colorimetric method in the acessions L. esculentum 'TOM-584' (P(1), low acylsugars), L...
