Preterm birth results in significant neurodevelopmental disability. A neonatal rodent model of chronic sublethal hypoxia (CSH), which mimics effects of preterm birth, was used to characterize neurodevelopmental consequences of prolonged exposure to hypoxia using tissue anisotropy measurements from diffusion tensor imaging. Corpus callosum, cingulum, and fimbria of the hippocampus revealed subtl...

Despite contrary expectations of both researchers and practitioners, the European monetary union has so far not led to a discernable convergence of the roles of commercial banks in different European financial systems. This empirical study aims to shed more light on these structural differences by analysing the strategic positions of 624 commercial banks from 12 European countries. Based solely...

This paper compares the characteristics of M&A in 1991-2005 across five countries: Japan, France, Germany, the UK and USA. We ask what factors explain the growth of M&A markets across these countries, and what similarities and differences exist in the ways the M&A market operates. We find that the growth of M&A reflects a rather similar combination of sectoral, international, and financial fact...

OBJECTIVES Growing evidence suggests that mutations in the connection domain of the HIV-1 reverse transcriptase (RT) can contribute to viral resistance to RT inhibitors. This work was designed to determine the effects of a novel mutation, D404N, in the connection subdomain of RT of HIV-1 CRF08_BC subtype on drug resistance, viral replication capacity (RC) and RT activity. METHODS Mutation D40...

After the identification of p73, a second homologue of the human p53 tumor suppressor gene has been reported and named p63/p73L/p51/p40/CUSP/KET. We have investigated the hypotheses that: (a) p63 is mutated in diverse types of human cancers; and (b) p63 functions in the same pathway as p53 and p73 in the process of carcinogenesis; therefore, mutations in these three genes would be mutually excl...

We have studied the presence and significance of retroviral genome-derived DNA in the core of human immunodeficiency virus (HIV) particles produced from transfections of HXB2 expression vectors in COS-7 cells and from HIV type 1 IIIB chronically infected H9 cells. Viruses purified by sucrose cushion centrifugation and treated with DNase I contained 1000-fold more viral RNA than DNA. However, pr...

We and others recently isolated a human p53 homologue (p40/p51/p63/p73L) and localized the gene to the distal long arm of chromosome 3. Here we sought to examine the role of p40/p73L, two variants lacking the N-terminal transactivation domain, in cancer. Fluorescent in situ hybridization (FISH) analysis revealed frequent amplification of this gene locus in primary squamous cell carcinoma of the...

Quercetin, a plant-derived flavonoid found in fruits, vegetables and tea, has been known to possess bioactive properties such as anti-oxidant, anti-inflammatory and anti-cancer. In this study, anti-cancer effect of quercetin and its underlying mechanisms in triple-negative breast cancer cells was investigated. MTT assay showed that quercetin reduced breast cancer cell viability in a time and do...

Using book translations as a measure of the flow of ideas across countries, we test the effect of the collapse of Communism in Eastern Europe on the international transmission of ideas. We find that translations of Western European titles into former Communist countries increased by a factor of five with the fall of Communism, while translations between Communist countries decreased by a factor...
