The asymmetric unit of the title compound, [Zn3(HCO2)3(C9H3O6)(C3H7NO)3] n , contains one Zn ion, one formate ligand, one N,N-di-methyl-formamide (DMF) ligand and one-third of a benzene-1,3,5-tri-carboxyl-ate (btc) ligand situated on a crystallographic 3 axis. Each Zn(II) atom is coordinated by one O atom from a DMF ligand, two O atoms from two btc ligands and three O atoms from three formate l...

A novel ligand, 5,5'-(2,2'-bipyridine-4,4'-diyl)-bis(thiophene-2-carboxylic acid) (BTC), and its Ru(II) complex (BTC-1) in which the anchoring group is attached to the thiophene units were developed. Using a low-volatility electrolyte and 3.3 mum mesoporous TiO2 films BTC-1 achieved a solar-to-electricity conversion efficiency of 6.1%, compared to 4.8% for N719 under the same experimental condi...

Background Performance-based financing (PBF) is often proposed as a way to improve health system performance. In Benin, PBF was launched in 2012 through a World Bank-supported project. The Belgian Development Agency (BTC) followed suit through a health system strengthening (HSS) project. This paper analyses and draws lessons from the experience of BTC-supported PBF alternative approach – especi...

Biliary tract carcinoma (BTC) has a poor prognosis due to limited treatment options. There is, therefore, an urgent need to identify new targets and to design innovative therapeutic approaches. Among potential candidatemolecules, we evaluated the nonreceptor tyrosine kinase Src, observing promising antitumor effects of its small-molecule inhibitor saracatinib in BTC preclinical models. The pres...

Image compression is used to reduce the size of digital image files in order to lessen the physical storage and transmission bandwidth costs. The main challenge in image compression is reducing the file size while maintaining much of the visual information. In this study, we explore one class of image compression techniques – the Block Truncation Coding (BTC) – and propose a new variant which w...

We recently reported several driver genes of biliary tract carcinoma (BTC) that are known to play important roles in oncogenesis and disease progression. Although the need for developing novel therapeutic strategies is increasing, there are very few BTC cell lines and xenograft models currently available for conducting preclinical studies. Using a total of 88 surgical BTC specimens and 536 immu...

We have collected all of the published photometry for GRB 990123 and GRB 990510, the first two gamma-ray bursts where breaks were seen in the light curves of their optical afterglows, and determined the shapes of their light curves and the break times. These parameters were used to investigate the physical mechanisms responsible for the breaks and the nature of the ambient medium that the burst...

OBJECTIVE To examine the issues surrounding the development and implementation of a behind-the-counter (BTC) category of medications. DATA SOURCES Testimony from organizations submitting comments to the Food and Drug Administration (FDA) panel hearings in November 2007, the 2009 final report of the U. S. General Accounting Office regarding a BTC drug category, literature review of research th...

In the title adduct, 3C(13)H(9)N·C(9)H(6)O(6) or (acr)(3)(btc), associ-ations of one btc and three acr molecules linked by O-H⋯N hydrogen bonds occur. C-H⋯O interactions also occur, resulting in a cyclic hydrogen-bonded synthon R(2) (1)(6). The acr mol-ecules and the btc mol-ecules also form slipped or offset π-π stacking inter-actions [centroid-centroid distances of 3.5212 (17) Å for btc rings...
