Abstract:
A decanuclear silver chalcogenide cluster, [Ag10(Se){Se2P(OiPr)2}8] (2) was isolated from a hydride-encapsulated silver diisopropyl diselenophosphates, [Ag7(H){Se2P(OiPr)2}6], under thermal condition. The time-dependent NMR spectroscopy showed that 2 was generated at the first three hours and the hydrido silver cluster was completely consumed after thirty-six hours. This method illustrated as cluster-to-cluster transformations can be applied to prepare selenide-centered decanuclear bimetallic clusters, [CuxAg10-x(Se){Se2P(OiPr)2}8] (x = 0–7, 3), via heating [CuxAg7−x(H){Se2P(OiPr)2}6] (x = 1–6) at 60 °C. Compositions of 3 were accurately confirmed by the ESI mass spectrometry. While the crystal 2 revealed two un-identical [Ag10(Se){Se2P(OiPr)2}8] structures in the asymmetric unit, a co-crystal of [Cu3Ag7(Se){Se2P(OiPr)2}8]0.6[Cu4Ag6(Se){Se2P(OiPr)2}8]0.4 ([3a]0.6[3b]0.4) was eventually characterized by single-crystal X-ray diffraction. Even though compositions of 2, [3a]0.6[3b]0.4 and the previous published [Ag10(Se){Se2P(OEt)2}8] (1) are quite similar (10 metals, 1 Se2−, 8 ligands), their metal core arrangements are completely different. These results show that different synthetic methods by using different starting reagents can affect the structure of the resulting products, leading to polymorphism.

Abstract:
An efficient microwave-assisted one-step synthetic route toward Mannich bases is developed from 4-hydroxyacetophenone and different secondary amines in quantitative yields, via a regioselective substitution reaction. The reaction takes a short time and is non-catalyzed and reproducible on a gram scale. The environmentally benign methodology provides a novel alternative, to the conventional methodologies, for the synthesis of mono- and disubstituted Mannich bases of 4-hydroxyacetophenone. All compounds were well-characterized by FT-IR, 1H NMR, 13C NMR, and mass spectrometry. The structures of 1-{4-hydroxy-3-[(morpholin-4-yl)methyl]phenyl}ethan-1-one (2a) and 1-{4-hydroxy-3-[(pyrrolidin-1-yl)methyl]phenyl}ethan-1-one (3a) were determined by single crystal X-ray crystallography. Compound 2a and 3a crystallize in monoclinic, P21/n, and orthorhombic, Pbca, respectively. The most characteristic features of the molecular structure of 2a is that the morpholine fragment adopts a chair conformation with strong intramolecular hydrogen bonding. Compound 3a exhibits intermolecular hydrogen bonding, too. Furthermore, the computed Hirshfeld surface analysis confirms H-bonds and π–π stack interactions obtained by XRD packing analyses.

Abstract:
Introduction: Knowledge about the distribution of hepatitis C virus (HCV) genotype and its correlation with viral load are important for the decision of treatment and the prediction of disease progression, however such information is very limited in Nepal. Here, we investigated the distribution of HCV genotypes and viral load for HCV-infected patients from Kathmandu, Nepal. Methodology: Ninety-six patients with HCV infection and not on antiviral therapy were enrolled from three different medical centers in Kathmandu valley, Nepal. Demographics were recorded and blood samples were collected. Plasma was separated and HCV RNA was extracted. Reverse transcriptase PCR (RT-PCR) was performed to measure the viral load, and virus genotype was determined. Results: Genotype 3a (n = 53, 55.2%) was the most prevalent, followed by 1b (n = 19, 19.8%), 1a (n = 18, 18.8%), 5a (n = 3, 3.1%), and mix types (n = 3, 3.1%). The median viral load for HCV genotype 1a was 770,942 IU/mL (IQR, 215,268-3,720,075), 1b was 700,000 IU/mL (IQR, 431,560-919,000), 3a was 1,060,000 IU/mL (IQR, 641,050-6,063,500), 5a was 673,400 IU/mL, and mixed was 6,428,000 IU/mL. A correlation between genotype and viral load was observed (p = 0.02), of which genotype 3a showed a high viral load. Conclusions: HCV genotypes 1a, 1b, 3a, and 5a were identified in Kathmandu, Nepal, and mixed genotype patients were observed in the patients studied. HCV genotype showed a correlation with viral load in patient plasma. This finding may contribute to the treatment and prevention of hepatitis C in Kathmandu, Nepal.

Abstract:
The treatment of non-fully substituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) with cupric nitrate leads to the introduction of a nitro group at different positions of the BODIPY core, depending on the substitution pattern. This methodology complements the treatment of fully substituted BODIPY with cupric nitrate that was previously reported. The crystal structures of 4,4-difluoro-1,3,5,7,8-pentamethyl-2-nitro-4-bora-3a,4a-diaza-s-indacene, C14H16BF2N3O2 (5a) 4,4-difluoro-3-nitro-8-phenyl-4-bora-3a,4a-diaza-s-indacene, C15H10BF2N3O2 (5b) and 3-chloro-6-ethyl-5,7,8-trimethyl-2-nitro-4,4-diphenyl-4-bora-3a,4a-diaza-s-indacene, C26H25BClN3O2 (5d) are presented. In all three structures, the fused ring system is in a very flattened `V-shape', with dihedral angles between the two outer five membered rings of 8.12 (14), 6.67 (9) and 12.30 (18) Å for 5a, 5b and 5d, respectively. In each case, the central six-membered ring is in a flattened sofa conformation. In the crystal of 5a, molecules are linked by weak C—H...O and C—H...F hydrogen bonds forming sheets parallel to (10-1). In the crystal of 5b molecules are linked by weak C—H...O and C—H...F hydrogen bonds and π–π interactions forming sheets parallel to (001). In the crystal of 5d, weak C—H...O hydrogen bonds link molecules into chains along [001]. In compound 5d, the atoms of the nitro group were refined as disordered over two sets of sites with occupancies 0.618 (12) and 0.382 (12).

Abstract:
Context.—Echinoderm microtubule–associated proteinlike 4–anaplastic lymphoma kinase (EML4-ALK) gene fusions are detected in 3% to 13% of non–small cell lung carcinomas. Accurate testing for detection of EML4-ALK fusions is essential for appropriate therapy selection. Objective.—To compare reverse transcription-polymerase chain reaction (RT-PCR), immunohistochemistry (IHC), and fluorescence in situ hybridization (FISH) methodologies for detection of EML4-ALK fusions. Design.—Forty-six pulmonary adenocarcinomas were selected with enrichment for wild-type epidermal growth factor receptor (EGFR) status (wild type, n = 42; mutant, n = 4). Specimens were tested by IHC (Dako; clone ALK1), FISH (Abbott Molecular; LSI ALK break apart), and RT-PCR (variants 1 and 3a/b). Results.—EML4-ALK variant 3a/b was detectable by RT-PCR, FISH, and IHC in 4% (2 of 46) of specimens. Complete agreement among FISH and IHC reviewers was obtained for variant 3a/b. No concordance existed among methodologies for the detection of EML4-ALK variant 1. The RT-PCR method detected variant 1 in 20% (9 of 46) of specimens. Agreement among FISH viewers was poor for variant 1 because only 11% (1/9) of specimens were scored as positive by all 3 viewers. The sensitivity of IHC for detection of variant 1 was also poor because only 1 of 9 samples (11%) was scored as positive. Overall, the frequency of EML4-ALK variants 1 and 3a/b was 24% (11 of 46) in adenocarcinomas enriched for wild-type EGFR status. One EML4-ALK variant 1 fusion was found to coexist with an EGFR exon 21 mutation. Conclusions.—The FISH interpretation demonstrated great variability among observers. The RT-PCR method was the most sensitive and least-subjective methodology for detection of EML4-ALK fusions.

Abstract:
Three novel low molecular weight polysaccharides (RLP-1a, RLP-2a, and RLP-3a) with 9004, 8761, and 7571 Da were first obtained by purifying the crude polysaccharides from the fruits of a traditional Chinese medicinal herb Rosae Laevigatae. The conditions for polysaccharides from the R. Laevigatae fruit (RLP) extraction were optimized by the response surface methodology, and the optimal conditions were as follows: extraction temperature, 93°C; extraction time, 2.8 h; water to raw material ratio, 22; extraction frequency, 3. Structural characterization showed that RLP-1a consisted of rhamnose, arabinose, xylose, glucose, and galactose with the ratio of 3.14 : 8.21 : 1 : 1.37 : 4.90, whereas RLP-2a was composed of rhamnose, mannose, glucose, and galactose with the ratio of 1.70 : 1 : 93.59 : 2.73, and RLP-3a was composed of rhamnose, arabinose, xylose, mannose, glucose, and galactose with the ratio of 6.04 : 26.51 : 2.05 : 1 : 3.17 : 31.77. The NMR analyses revealed that RLP-1a, RLP-2a, and RLP-3a contained 6, 4, and 6 types of glycosidic linkages, respectively. RLP-1a and RLP-3a exhibited distinct antioxidant abilities on the superoxide anions, 1,1-diphenyl-2-picrylhydrazyl (DPPH), and hydroxyl radicals in vitro. RLPs could decrease the serum lipid levels, elevate the serum high-density lipoprotein cholesterol levels, enhance the antioxidant enzymes levels, and upregulate of FADS2, ACOX3, and SCD-1 which involved in the lipid metabolic processes and oxidative stress in the high-fat diet-induced rats. These results suggested that RLPs ameliorated the high-fat diet- (HFD-) induced lipid metabolism disturbance in the rat liver through the peroxisome proliferator-activated receptor (PPAR) signaling pathway. Low molecular weight polysaccharides of RLP could be served as a novel potential functional food for improving hyperlipidemia and liver oxidative stress responses.

Abstract:
Three test campaigns were carried out at CIAM C-3A test facility (Turaevo, Russia) with the aim of investigating aerodynamic and acoustic performances of three counter rotating fan models under the European VITAL project [1–3]. The second fan configuration CRTF2a [2] differs from the reference fan configuration CRTF1 by thickened blades profiling designed for simulation the composite blades. The third version of counter rotating fan model CRTF2b [4] was manufactured according to “blisk” technology to simulate composite blades. Along with studies of aerodynamic and acoustic performances of fan models, the C-3A test facility provides an opportunity to investigate and estimate the rotor blades vibration behavior. The rotor blade as the most loaded fan component, experiences the impact of various types of flow disturbances leading to its resonance vibrations and sometimes creating conditions for initiation of flutter at rotor blade natural frequencies. This is the reason for extending the information content of the measurements, improvement the measurement tools and methodology. The contactless method of blade vibration measurements (tip-timing) was used on the basis of MIC-DPM equipment («Mera» Research and Production Enterprise, Russia) [5,6] in combination with a traditional technique of strain gauges installation for determination of counter rotating fan rotor blades vibration behavior. This work presents the description of applied methodologies for measurements of rotor blades vibration parameters. Additionally, the paper presents the measurement results of rotor blades vibration behavior for three counter rotating fan models studied by means of a strain gauges technique and a contactless blade tip-timing method as well as the comparison analysis of numerical and experimental results in relation to vibration behavior of tested fan models.
