A xanthene-based bismuthane/phosphane chelating ligand has been accessed that has enabled the synthesis of a palladium(0) bismuthane complex. The bismuthane donor proved to be hemilabile as it switched to a dangling position upon addition of O2 that gave a palladium(II) peroxide complex. Unlike the corresponding 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) palladium peroxide, the bismuth analogue could be employed for catalytic phosphane oxidation and oxidative phenol coupling.

Photoluminescence, and optically stimulated luminescence in ZnB2 X4 (B; Li,Na,K: X; Cl,Br) compounds doped with Cu(+) or Ag(+) were studied. Double humped emission bands attributable to the activators were observed in all the samples. The observed photoluminescence of Cu(+) and Ag(+) could be identified with 3d(9) 4s(1) ↔3d(10) and 4d(9) 5s(1) ↔5d(10) transitions respectively. The longer wavelength band (400-500 nm range) could be attributed to the Cu(+) or Ag(+) ion replacing alkali ion at the octahedral alkali site whereas short wavelength band (340-400 nm range) is attributed to a Cu or Ag ion at tetrahedral zinc site...

In 2009, the passing of the Family Smoking Prevention and Tobacco Control Act facilitated the establishment of the FDA Center for Tobacco Products (CTP), and gave it regulatory authority over the marketing, manufacture and distribution of tobacco products, including those termed 'modified risk'. On 4-6 April 2016, the Institute for In Vitro Sciences, Inc. (IIVS) convened a workshop conference entitled, In Vitro Exposure Systems and Dosimetry Assessment Tools for Inhaled Tobacco Products, to bring together stakeholders representing regulatory agencies, academia and industry to address the research priorities articulated by the FDA CTP...

The development of novel antimycobacterial agents against Mycobacterium tuberculosis (Mtb) is urgently required due to the appearance of multi-drug resistance (MDR) combined with a complicated long-term treatment. CYP121 was shown to be a promising novel target for inhibition of mycobacterial growth. In this study, we describe the rational discovery of new CYP121 inhibitors by a systematic screening based on biophysical and microbiological methods. Best hits originating from only one structural class gave first information about molecular motifs required for binding and activity...

Achalasia and Treatment of esophageal Adenocarcinoma are commonly associated to surgical resection. Newer technologies in interventional endoscopy gave way to a substantial paradigm shift in the management of these conditions. In the case of achalasia, endoscopic myotomy is rapidly displacing Heller's myotomy as the gold standard in many centers. Early stage neoplasia in Barrett's esophagus (BE) comprising high-grade dysplasia (HGD), intramucosal and, in some cases, submucosal carcinoma is now being treated without the need of esophagectomy...

Introduction: Hantaviruses are globally distributed zoonotic pathogens. Great diversity and high antigenic cross-reactivity makes diagnosis by traditional methods cumbersome. Materials and methods: 'Megapeptides', 119-120-mers from the amino terminus of the nucleoprotein of 16 hantaviruses, representing the four major branches of the hantavirus phylogenetic tree, were utilized in a novel IgG-based hantavirus suspension multiplex immunoassay (HSMIA) for detection of past hantavirus infections in 155 North European human samples...

BACKGROUND: Many conventional chemotherapeutic drugs are known to be involved in DNA damage, thus ultimately leading to apoptosis of leukemic cells. However, they fail to completely eliminate leukemia stem cells (LSCs) due to their higher DNA repair capacity of cancer stem cells than that of bulk cancer cells, which becomes the root of drug resistance and leukemia recurrence. A new strategy to eliminate LSCs in acute myeloid leukemia (AML) is therefore urgently needed. RESULTS: We report that a low-dose chidamide, a novel orally active benzamide-type histone deacetylase (HDAC) inhibitor, which selectively targets HDACs 1, 2, 3, and 10, could enhance the cytotoxicity of DNA-damaging agents (daunorubicin, idarubicin, and cytarabine) in CD34(+)CD38(-) KG1α cells, CD34(+)CD38(-) Kasumi cells, and primary refractory or relapsed AML CD34(+) cells, reflected by the inhibition of cell proliferation, induction of apoptosis, and increase of cell cycle arrest in vitro...

BACKGROUND: Olfactory bulb (OB) interneurons are known to represent diverse neuronal subtypes, which are thought to originate from a number of telencephalic regions including the embryonic dorsal lateral ganglionic eminence (dLGE) and septum. These cells migrate rostrally toward the OB, where they then radially migrate to populate different OB layers including the granule cell layer (GCL) and the outer glomerular layer (GL). Although previous studies have attempted to investigate regional contributions to OB interneuron diversity, few genetic tools have been used to address this question at embryonic time points when the earliest populations are specified...

The increasing use of cardiovascular magnetic resonance (CMR) is based on its capability to perform biventricular function assessment and tissue characterization without radiation and with high reproducibility. The use of late gadolinium enhancement (LGE) gave the potential of non-invasive biopsy for fibrosis quantification. However, LGE is unable to detect diffuse myocardial disease. Native T1 mapping and extracellular volume fraction (ECV) provide knowledge about pathologies affecting both the myocardium and interstitium that is otherwise difficult to identify...

Unambiguous investigation of condensed tannin (CT) structure-activity relationships in biological systems requires well-characterized, high-purity CTs. Sephadex LH-20 and Toyopearl HW-50F resins were compared for separating CTs from acetone/water extracts and column fractions analyzed for flavan-3-ol subunits, mean degree of polymerization (mDP) and purity. Toyopearl HW-50F generated fractions with higher mDP values and better separation of procyanidins (PC) and prodelphinidins (PD) but required a pre-purification step, more time for large scale purifications and gave poorer recoveries...

Developmental deconvolution of complex organs and tissues at the level of individual cells remains challenging. Non-invasive genetic fate mapping has been widely used, but the low number of distinct fluorescent marker proteins limits its resolution. Much higher numbers of cell markers have been generated using viral integration sites, viral barcodes, and strategies based on transposons and CRISPR-Cas9 genome editing; however, temporal and tissue-specific induction of barcodes in situ has not been achieved. Here we report the development of an artificial DNA recombination locus (termed Polylox) that enables broadly applicable endogenous barcoding based on the Cre-loxP recombination system...

Enzymatic saccharification of lignocellulosic biomass has been widely studied. Mainly endoglucanases were found to be a prerequisite for the quick initial biomass liquefaction. In the present study, Pichia pastoris was used as a host for the heterologous expression of a Sclerotinia sclerotiorum GH45 endoglucanase, Endo2. The recombinant plasmid pPICZαA was used to transform Pichia pastoris. Pichia culture supernatants expressing the recombinant Endo2 (rEndo2) were used for the purification and biochemical characterization of this enzyme...

Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics...
