Vorinostat [suberoylanilide hydroxamic acid (SAHA)], a histone deacetylase inhibitor, shows limited clinical activity against solid tumors when used alone. The methyl xanthine drug, pentoxifylline (PENT), has been described to have antitumor properties. The aim of this study was to look for the enhanced anticancer activities of both agents when used in combination at doses lower than their respective efficacy dose when used alone. We investigated the antitumor potential of this novel combination in vitro and in vivo...

The conservation laws, such as those of charge, energy and momentum, have a central role in physics. In some special cases, classical conservation laws are broken at the quantum level by quantum fluctuations, in which case the theory is said to have quantum anomalies. One of the most prominent examples is the chiral anomaly, which involves massless chiral fermions. These particles have their spin, or internal angular momentum, aligned either parallel or antiparallel with their linear momentum, labelled as left and right chirality, respectively...

Owing to the high charge mobility and low processing temperature, ZnO is regarded as an ideal candidate for electron transport layer (ETL) material in thin-film solar cells. For the film preparation, the presently dominated sol-gel (SG) and hydrolysis-condensation (HC) methods show great potential, however, the effect of these two methods on the performance of the resulting devices has not been investigated in the same frame. In this study, the ZnO films made through SG and HC methods were applied in perovskite solar cells (Pero-SCs), and the performances of corresponding devices were compared under parallel conditions...

Previously synthesized 9-aryl-5H-imidazo[2,1-d][1,2,5]triazepin-6(7H)-ones have been used as starting materials for the synthesis of three new tricyclic ring systems, where an imidazotriazepine is condensed with an imidazole, triazole or tetrazole ring. These novel compounds could be potential drug candidates for central nervous system diseases because of their closely related structure to known tricyclic derivatives with anticonvulsant activity.

In this study, we developed a one-step self-activated route for synthesizing novel core-shell Cu@polymer nanocomposites. Under solvothermal conditions, Cu(2+) was reduced to metal copper by formaldehyde and salicylaldehyde and the newly generated copper crystals acted as the catalysts to activate the condensation polymerization between formaldehyde and salicylaldehyde, resulting in the formation of core-shell Cu@polymer nanocomposites with Cu nanoparticles as the cores and polymer as the shells. The Cu@polymer nanocomposites can be applied as a nonenzymatic sensor for glucose detection...

The amount of data available to health-care institutions regarding the patient care experience has grown tremendously. Purposeful approaches to condensing, interpreting, and disseminating these data are becoming necessary to further understand how clinical and operational constructs relate to patient satisfaction with their care, identify areas for improvement, and accurately measure the impact of initiatives designed to improve the patient experience. We set out to develop an analytic reporting tool deeply rooted in the patient voice that would compile patient experience data obtained throughout the medical center...

Atmospheric aerosol particles acting as cloud condensation nuclei (CCN) are key elements in the hydrological cycle and climate. To improve our understanding of the activation characteristics of CCN and to obtain accurate predictions of their concentrations, a long-term field campaign was carried out in the Yangtze River Delta, China. The results indicated that the CCN were easier to activate in this relatively polluted rural station than in clean (e.g., the Amazon region) or dusty (e.g., Kanpur-spring) locations, but were harder to activate than in more polluted urban areas (e...

Based on advanced light and electron microscopy, we describe the male reproductive system and sperm development of Limodromus assimilis. The genital tract consists of pairs of uni-follicular testes, spermatic ducts with diverticula regions, seminal vesicles, accessory glands, an unpaired ejaculatory duct and an aedeagus containing an internal sac equipped with sclerotic scales. Based on their morphology, we draw conclusions about their functions. After spermatogenesis within the follicle, the spermatozoa become released from the sperm cysts...

Burning incense to worship deities is a popular religious ritual in large parts of Asia, and is a popular custom affecting more than 1.5 billion adherents. Due to incomplete combustion, burning incense has been well recognized to generate airborne hazards to human health. However, the correlation between burning incense and lung cancer in epidemiological studies remains controversy. Therefore, we speculated that some unknown materials in incense smoke are involved in the initiation or progression of lung cancer...

Lacunary polyoxometalates (POMs) are useful rigid multidentate inorganic ligands to construct multinuclear metal oxo clusters and inorganic-organic hybrid materials. However, the use of multivacant lacunary POMs often suffers from their undesired condensation reactions at the highly reactive vacant sites. Herein, we report the introduction of alkoxy protecting groups into the vacant sites of lacunary POMs in organic media for the first time. By reacting organic solvent-soluble trivacant lacunary Keggin-type POMs with methanol, six methoxy groups were successfully introduced into the vacant sites, resulting in the formation of the alkoxides (Ix-OMe; X = Si, Ge)...

Readily available N-substituted amides or their requisite carboxylic acids or acid chlorides have been used to construct 2,3-disubstituted-3H-quinazolin-4-ones in a one-pot procedure. Key transformation in this convergent approach involves Ph3P-I2-mediated formation of amidine upon condensation of an amide or the intermediate amide with methyl anthranilate. Cyclization of the amidine-tethered anthranilate then affords 2,3-disubstituted-3H-quinazolin-4-ones in good to excellent yields under mild conditions.

1-Trichloromethyl-1,2,3,4-tetrahydro-β-carboline, abbreviated as TaClo, is an endogenous neurotoxin capable of formation in the brain through the condensation of neuronal tryptamine with ingested exogenous toxins such as trichloroethylene or chloral hydrate. Due to its structural resemblance to 1-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP), and similar ability to inhibit mitochondrial complex I, TaClo has been implicated in the etiology of Parkinson's disease. Previous studies have shown the cytotoxicity of TaClo in various cell culture models...

RNA-dependent RNA polymerase 1 (RDR1) has been shown to be involved in DNA methylation, RNA silencing and regulating expression of other genes. RDR1 gene expression is stimulated by infection with potato virus Y° (PVY). Transgenic Nicotiana tabacum plants silenced for RDR1 gene expression showed morphological changes in mesophyll cells, associated with remodeling of the nuclei, chloroplasts and mitochondria. RDR1 silencing led to decreased nuclear size, increased heterochromatin content and aggregation, decreased numbers of chloroplasts, plus changes in shape, internal structures and integrity of chloroplasts and mitochondria...

It was recently discovered that condensation growing on a nanostructured superhydrophobic surface can spontaneously jump off the surface, triggered by naturally occurring coalescence events. Many reports have observed that droplets must grow to a size of order 10 μm before jumping is enabled upon coalescence; however, it remains unknown how the critical jumping size relates to the topography of the underlying nanostructure. Here, we characterize the dynamic behavior of condensation growing on six different superhydrophobic nanostructures, where the topography of the nanopillars was systematically varied...
