INTRODUCTION The serotonergic neurotransmitter system is closely linked to depression and personality traits. It is not known if selective serotonin reuptake inhibitors (SSRI) have an effect on neuroticism that is independent of their effect on depression. Healthy individuals with a genetic liability for depression represent a group of particular interest when investigating if intervention with...

Elevated tissue inhibitor of metalloproteinase (TIMP)-1 expression contributes to excess production of extracellular matrix in liver fibrosis. However, there are few studies on sustained suppression of TIMP-1. We aimed to construct a recombinant adeno-associated virus (AAV) carrying small interfering RNAs (siRNAs) of TIMP-1 and investigate the long-term effects of RNA interference upon the TIMP...

Unlike adult damage, neonatal damage to the inferior prefrontal convexity (IC) in monkeys spares learning and performance on the delayed nonmatching-to-sample (DNMS) task ( Málková et al. 2000). We investigated whether this sparing was due to compensation by undamaged orbital frontal cortex (O), an area also critical for DNMS, by comparing combined IC and O damage (Neo-ICO) with damage to O alo...

Y chromosomes often degenerate via the accumulation of pseudogenes and transposable elements. By contrast, little is known about X-chromosome degeneration. Here we compare the pseudogenization process between genes on the neo-sex chromosomes in Drosophila miranda and their autosomal orthologues in closely related species. The pseudogenization rate on the neo-X is much lower than the rate on the...

Retroviral infection of bone marrow cells in long-term marrow cultures (LTMCs) offers several theoretical advantages over other methods for gene transfer into hematopoietic stem cells. To investigate the feasibility of this approach in a large animal model system, we subjected LTMCs from nine dogs to multiple infections with retrovirus containing the neomycin phosphotransferase gene (neo) durin...

Progesterone (P4) is frequently used in the treatment of threatened abortion, prevention of recurrent miscarriage and threatened preterm labor. However, little is known about the molecular mechanism of P4 in the regulation of extravillous trophoblasts' (EVTs) function. This study was designed to examine the presence of progesterone receptor (PR) in the human trophoblast-derived HTR-8/SV neo cel...

The rationale for neoadjuvant chemoradiation therapy (Neo-CRT) and the definition of borderline resectable pancreatic cancer (BRPC) are still controversial. In particular, surgical treatment of BRPC with isolated venous vascular involvement (IVVI) is debatable.From January 2000 to December 2013, 84 patients diagnosed with BRPC according to NCCN guidelines were identified, and 70 patients were f...

To provide tools for functional molecular genetics of the protozoan parasite Entamoeba histolytica, we investigated the use of the prokaryotic neomycin phosphotransferase (NEO) gene as a selectable marker for the transfection of the parasite. An Escherichia coli-derived plasmid vector was constructed (pA5'A3'NEO) containing the NEO coding region flanked by untranslated 5' and 3' sequences of an...

In recent years, the notion that computers and robots will attain superhuman levels of intelligence in the next few decades, ushering in a new “posthuman” era in evolutionary history, has gained widespread attention among technology enthusiasts, thanks in part to books such as Ray Kurzweil’s The Singularity Is Near. This paper describes an introductory-level AI course designed to examine this i...

A preliminary analysis of fields around 20 mainly radio– quiet QSOs (RQQs) at intermediate redshift is summarized. We find overdensities of faint sources around 50% of our observed QSOs suggesting that they are located in groups or even clusters of galaxies.
