PURPOSE Alterations in the DNA mismatch repair (MMR) proteins have been associated with an increased resistance of many cancer cell lines to cisplatin. The aim of this work was to investigate whether defects in DNA MMR proteins are involved in the survival of human colorectal cancer cells in the presence of high concentrations of cisplatin and oxaliplatin,(More)
We estimate classification models of deceptive discussions during quarterly earnings conference calls. Using data on subsequent financial restatements (and a set of criteria to identify especially serious accounting problems), we label the Question and Answer section of each call as " truthful " or " deceptive ". Our models are developed with the word(More)
Organisms provide some of the most sensitive indicators of climate change and evolutionary responses are becoming apparent in species with short generation times. Large datasets on genetic polymorphism that can provide an historical benchmark against which to test for recent evolutionary responses are very rare, but an exception is found in the brown-lipped(More)
The photolysis of gold salts is rarely viewed as the initiation for gold nanoparticle (AuNP) formation. Yet, photolysis of AuCl(4)(-) generates chlorine atoms whose rich hydrogen transfer chemistry can readily generate strongly reducing radicals. Interesting precursors include hydrogen peroxide, 2-propanol, 1,4-cyclohexadiene and tetrahydrofuran; all of(More)
A species of Amphidinium bloomed in a mariculture sedimentation pond that was used to grow bivalves near the Gulf of Eilat, Israel. Its overall length averaged 13 microm, the hypocone was 11 microm, and its width was 8 microm. It has a ventral ridge. The sulcus begins at the longitudinal flagellar pore and does not project forward in the apex toward the(More)
Artificial marking and tagging techniques have been used to study movement, population dynamics, behaviour, ecology, survival and growth of at least 25 syngnathid species. External necklace-style tags and injection of visible implant elastomer have been the most used techniques, uniquely identifying hundreds of individual syngnathids to study population(More)
The triterpene saponins jenisseensosides A, B, C, D were found to increase the accumulation and cytotoxicity of the anticancer agent cisplatin in human colon tumor cells. These compounds are glycosides of quillaic acid whose fucose residue was acylated by a trans- or cis-p methoxycinnamic acid. In contrast, other saponins derivatives without this acyl(More)
We examine the " supplemental " role of securities class action lawsuits with respect to SEC enforcement in terms of targeting and penalties imposed on individual defendants. We find some evidence that the targeting of class actions is adversely affected by the incentives of plaintiff's lawyers, but still takes into account the merit of the cases, as(More)
and the 2015 FARS midyear meeting. We are very grateful to Vincent Pham for excellent research assistance. We thank the Thomson Reuters Loan Pricing Corporation for providing loan data and RavenPack for media data. We gratefully acknowledge the financial support of the Abstract We investigate how the development of the credit default swap (CDS) market(More)
