Satoshi Namai, Asako Sugimoto
Pristionchus pacificus is a free-living nematode used as a model organism for evolutionary developmental and ecological biology. Although a transgenic technique to form complex arrays by microinjection has been established in P. pacificus, transgene expression from the array in the germline and early embryos tends to be silenced. Here, we established a method to integrate transgenes into the genome of P. pacificus using microparticle bombardment with hygromycin B selection. Additionally, we isolated a mutant exhibiting significantly lower autofluorescence in the germline and early embryos, facilitating visualization of transgene-derived fluorescent proteins for live imaging...

The format of an immunochromatographic multiassay is first proposed with native antisera and a universal conjugate of antispecies antibodies with gold nanoparticles. This format allows (1) the exclusion of purification and conjugation stages for specific antibodies and (2) significant reduction of the concentration of specific antibodies in the system. The independent use of specific antibodies and a conjugated marker provided a low detection limit and high signal intensity. The proposed format was implemented for the simultaneous detection of two herbicides...

BACKGROUND: We analysed hospital admissions and bed occupancy for fragility fractures in Ireland over a 15-year period to assess fracture admission trends and to project admissions over the next three decades. METHODS: We used the Hospital In-Patient Enquiry (HIPE) scheme to extract data on fracture admissions to Irish hospitals between 2000 and 2014 inclusive. We calculated absolute numbers and age-standardised rates of hospitalisations for men and women ≥ 50 years for each osteoporotic-type fracture...

This first pan-Mediterranean analysis of genetic diversity in wild narrow-leafed lupin revealed strong East-West genetic differentiation of populations, an historic eastward migration, and signatures of genetic adaptation to climatic variables. Most grain crops suffer from a narrow genetic base, which limits their potential for adapting to new challenges such as increased stresses associated with climate change. Plant breeders are returning to the wild ancestors of crops and their close relatives to broaden the genetic base of their crops...

Spleen tyrosine kinase (Syk) has emerged recently as a major effector of proinflammatory genes expression induced by LPS-elicited TLR4 activation, and manifested by the up-amplification in the production of inflammatory mediators, including PGE2 and NO. Here, we investigated the nature of factors involved in the recruitment and interaction of Syk with TLR4 in gastric mucosa in response to H. pylori LPS. We show that stimulation of gastric mucosal cells with the LPS leads to localization of Syk with the membrane-associated TLR4 complex and its activation through phosphorylation on Tyr...

The epidemiology of healthcare-associated meningitis (HAM) is dominated by commensal bacteria from the skin, as coagulase-negative staphylococci (CoNS). We hypothesized that the pauci-symptomatic and mild inflammatory patterns of HAM are related to the low pathogenic state of CoNS. Our aim was to describe clinical and biological features of CoNS HAM, compared to other HAM. All consecutive patients with HAM admitted in our hospital were retrospectively included from 2007 to 2014. HAM due to CoNS were compared to HAM caused by other bacteria (controls) for clinical and laboratory patterns...

The mechanistic target of rapamycin (mTOR) has been demonstrated to mediate pain-related aversion induced by formalin in the rostral anterior cingulate cortex (rACC). However, it remains unclear the signaling pathways and regulatory proteins involved. In the rACC, brain-derived neurotrophic factor (BDNF), an activity-dependent neuromodulator, has been shown to play a role in the development and persistence of chronic pain. In this study, we used a rat formalin-induced inflammatory pain model to demonstrate BDNF up-regulation in the rACC...

Multi-site brain MRI analysis is needed in big data neuroimaging studies, but challenging. The challenges lie in almost every analysis step including skull stripping. The diversities in multi-site brain MR images make it difficult to tune parameters specific to subjects or imaging protocols. Alternatively, using constant parameter settings often leads to inaccurate, inconsistent and even failed skull stripping results. One reason is that images scanned at different sites, under different scanners or protocols, and/or by different technicians often have very different fields of view (FOVs)...

PURPOSE: Major concern during surgery for high-grade spondylolisthesis (HGS) is to reduce lumbosacral kyphosis and restore sagittal alignment. Despite the numerous methods described, lumbosacral fixation in HGS is a challenging technique associated with high complication rate. Few series have described outcomes and most of the results are limited to lumbosacral correction without global sagittal alignment analysis. This study aims at analyzing clinical and radiological outcomes of HGS patients treated with intrasacral rods on full spine radiographs...

Criterion data for total energy expenditure (TEE) in elite rugby are lacking, which prediction equations may not reflect accurately. This study quantified TEE of 27 elite male rugby league (RL) and rugby union (RU) players (U16, U20, U24 age groups) during a 14-day in-season period using doubly labelled water (DLW). Measured TEE was also compared to estimated, using prediction equations. Resting metabolic rate (RMR) was measured using indirect calorimetry, and physical activity level (PAL) estimated (TEE:RMR)...

Multimodality is a phenomenon which complicates the analysis of statistical data based exclusively on mean and variance. Here, we present criteria for multimodality in hierarchic first-order reaction networks, consisting of catalytic and splitting reactions. Those networks are characterized by independent and dependent subnetworks. First, we prove the general solvability of the Chemical Master Equation (CME) for this type of reaction network and thereby extend the class of solvable CME's. Our general solution is analytical in the sense that it allows for a detailed analysis of its statistical properties...

Methadone maintenance programs (MMP) for opioid dependence treatment have been widely used due to their effective therapeutic outcomes. Harm reduction programs (HRP) are complementary programs for severe patients with high risk behaviors and when abstinence is not possible. This study aims to compare patients in MMP that use HRP (MMP-HRP) and patients in MMP who do not use HRP (MMP-NO HRP). The sample was composed of 143 patients (MMP-HRP = 42 vs. MMP-NO HRP = 101). An additional subanalysis was performed with patients under 45 years of age (n = 116; MMP-HRP = 38 vs...

BACKGROUND CXC chemokine ligand 16 (CXCL16) is a soluble chemokine with a transmembrane domain, playing an important role in inflammatory regulation. NF-κB has a critical role in tumor progression. Recent studies focused on the effect of CXCL16 on tumor progression. However, few reports showed the influence of CXCL16 on lung cancer, especially in regulating NF-κB activity. Here we investigated CXCL16 expression and its clinical significance in lung cancer, as well as the effect on lung cancer cell biological characteristics by regulating NF-κB...
