BACKGROUND AND AIMS: As already known, spondyloarthritis patients present a striking resemblance in intestinal inflammation with early Crohn's disease. Moreover, the frequent use of nonsteroidal anti-inflammatory drugs is an important part of their treatment. Both conditions could lead to intestinal stenoses. Therefore we proposed to investigate the usefulness of the patency capsule test in patients with spondyloarthritis. MATERIAL AND METHODS: 64 consecutive patients (33 males; mean age 38 ± 11 years) that fulfilled the AMOR criteria for seronegative spondyloarthropathy (59...

Polarization control using single plasmonic nanoantennas is of interest for subwavelength optical components in nano-optical circuits and metasurfaces. Here, we investigate the role of two mechanisms for polarization conversion by plasmonic antennas: Structural asymmetry and plasmon hybridization through strong coupling. As a model system we investigate L-shaped antennas consisting of two orthogonal nanorods which lengths and coupling strength can be independently controlled. An analytical model based on field susceptibilities is developed to extract key parameters and to address the influence of antenna morphology and excitation wavelength on polarization conversion efficiency and scattering intensities...

Aberrant glycogene and glycan expression is intimately associated with carcinogenesis, invasion, and metastasis of gastric cancer (GC); however the regulatory mechanisms for glycogenes in GC cells remain unclear. Methyl-CpG-binding protein 2 (MeCP2) regulates genes by binding to methylated promoters, and in our previous work we found that it is overexpressed in GC cell lines and tissues, functioning as an oncogene. In this study we detected the expression of 212 glycogenes in MeCP2 silenced GC cells versus control using the Agilent Whole Human Genome Microarray and mining the data through bioinformatic analysis...

Comparative genomic hybridization (CGH) is a powerful tool used to analyze changes in copy number, polymorphisms, and structural variations in the genome. Gene copy number variation (CNV) is a common form of natural diversity in the genome, which can create new genes and alter gene structure. Thus, CNVs may influence phenotypic variation and gene expression. In this study, to detect CNVs, we irradiated rice seeds with gamma rays (300 Gy) and selected two dwarf mutagenized plants, GA-III-189 and -1052, in the M3 generation...

Immigration in early childhood can be considered as a traumatic situation. It often goes unrecognized since children adapt to most conditions and conform to their environment with astonishing agility. Inspired by the sensitive work of Sándor Ferenczi, and Donald Winnicott, regarding the psychic economy of maturational processes, the author explores the concept of totalitarian functioning and its obstruction of the growing psyche. Before birth we are all totalitarian, one with the mother; this symbiotic, invincible state of survival mode is prolonged as the immature newborn child ignores the requirements of reality and enjoys omnipotent pleasure through hallucination...

Depressed patients present with increased cortisol levels and attenuated immune responses. However, little is known about the association between depression and the spleen, as this is the largest peripheral immune organ. In this study, we examined alterations in splenic function and gene expression in mice with depressive-like behavior, well as the expression of certain proteins in related pathways. A mouse model of depression was established with the use of corticosterone. Splenic function and histopathology were assessed using Wright and H&E staining...

Training of endoscopic ultrasound (EUS) in Asia faces two major challenges: (i) the ever-increasing demand for skills to handle a growing range of interventional EUS procedures; and (ii) a continual shortage of EUS training programs. As the therapeutic application of EUS continues to expand,(1, 2) the need to train more new endosonographers and upgrade skills of existing ones has become more critical than ever before. A formal fellowship to acquire EUS knowledge and skills in an advanced endoscopy centre has always been perceived as the best way of training novices, but such opportunities remain limited in most Asian countries...

A reduction in executive function (EF) performance is a major factor associated with the loss of functional independence among older adults. Computer-based tests are commonly used to evaluate EF; however, these mouse or keyboard tests are upper limb dominant while most activities of daily living (ADL, e.g. crossing a street) are lower limb dominant. The purpose of this study was to examine the utility of a newly developed walking EF test called the Walking Response and Inhibition Test (WRIT). The WRIT was validated by comparing its results a number of established computer-based tests and to an ADL-related test known to require EF, the Timed "Up & Go" Test (TUG)...

Distributed social learning may occur at many temporal and spatial scales, but it rarely adds up to a stable culture. Cultures vary in stability and diversity (polymorphism), ranging from chaotic or drifting cultures, through cumulative polymorphic cultures, to stable monolithic cultures with high conformity levels. What features can sustain polymorphism, preventing cultures from collapsing into either chaotic or highly conforming states? We investigate this question by integrating studies across two quite separate disciplines: the emergence of song cultures in birds, and the spread of public opinion and social conventions in humans...
