Dermatomyositis (DM) is an autoimmune disorder associated with a dysregulation of immune homeostasis of both the innate and adaptive immune system. Earlier data suggested that these two arms of the immune system interconnect in DM. In the current study, we analysed the association of autoantigen expression [adaptive system components: Mi2, transcriptional intermediary factor (TIF)1γ, small ubiquitin-like modifier 1 activating enzyme subunit (SAE)1, melanoma differentiation-associated protein (MDA)5] with markers of cellular stress (innate system components: MxA, p53) in skin and muscle (immunohistology and gene expression data, respectively)...

Carbonated fumigants have been shown to distribute quickly and uniformly in sandy soils and improve pest control efficacy for annual crops. Low permeability films, such as VaporSafe® (TIF), could further improve fumigant dispersion by effectively retaining the fumigant in soil; however, there is a concern that the TIF can lead to higher off-tarp edge emissions. An orchard field trial was conducted to determine the off-tarp emissions, distribution, efficacy, and fate of carbonated Telone® C35 [63.4% 1,3-dichloropropene (1,3-D), 34...

The 15-item version of the Geriatric Depression Scale (GDS-15) is a self-report screening instrument widely used. The current study aimed at providing evidence of the measurement precision of the GDS-15 applying Item Response Theory (IRT). The relative contribution of each item and the reliability of the whole scale in measuring the trait level around the cutoffs were investigated employing data collected from a sample consisting of 1344 old people (M=76.44years, SD=5.13; 58.7% women) involved in a large gerontological research project...

BACKGROUND: Renal tubulointerstitial fibrosis (TIF) is commonly the final result of a variety of progressive injuries and leads to end-stage renal disease. There are few therapeutic agents currently available for retarding the development of renal TIF. PURPOSE: The aim of the present study is to evaluate the role of arctigenin (ATG), a lignan component derived from dried burdock (Arctium lappa L.) fruits, in protecting the kidney against injury by unilateral ureteral obstruction (UUO) in rats...

BACKGROUND: Huntington's disease (HD) is a rare familial autosomal dominant neurodegenerative disorder characterized by progressive degeneration of medium spiny neurons (MSNs) located in the striatum. Currently available treatments of HD are only limited to alleviating symptoms; therefore, high expectations for an effective therapy are associated with potential replacement of lost neurons through stimulation of postnatal neurogenesis. One of the drugs of potential interest for the treatment of HD is riluzole, which may act as a positive modulator of adult neurogenesis, promoting replacement of damaged MSNs...

Fumigant methyl isothiocyanate (MITC) is a very promising alternative to methyl bromide, providing effective control of soil borne disease. However, there is a significant volatilization of MITC following fumigation because of its high application rates and high vapor pressure. Covering the soil surface with plastic tarps is a common approach used for restricting fumigant emissions to the atmosphere. To minimize atmospheric emissions of MITC by tarping, we determined the effect of temperature, humidity, and fumigant mixtures on the permeability to MITC of low density polyethylene film (LDPE) and totally impermeable film (TIF), using static sealed chambers...

The TIFY domain contains approximately 36 conserved amino acids that form the core motif TIF[F/Y]XG, and they were reported to play important roles in plant growth, tissue development and defense regulation. Moreover, more and more evidence has shown that some members of the TIFY gene family perform their functions by modulating plant hormone signaling pathways. Poplar trees are found worldwide, and they comprise approximately 30 species. Benefit from the importance of poplar and its advanced platform, this tree is considered to be the model perennial plant...

Newborns and infants are highly depending on successfully communicating their needs; e.g., through crying and facial expressions. Although there is a growing interest in the mechanisms of and possible influences on the recognition of facial expressions in infants, heretofore there exists no validated database of emotional infant faces. In the present article we introduce a standardized and freely available face database containing Caucasian infant face images from 18 infants 4 to 12 months old. The development and validation of the Tromsø Infant Faces (TIF) database is presented in Study 1...

Metal-organic frameworks (MOFs) built up from connecting M-XF6 pillars through N-donor ligands are among the most attractive adsorbents and separating agents for CO2 and hydrocarbons today. The continuous, one-step spray-drying synthesis of several members of this isoreticular MOF family varying the anionic pillar (XF6 =[SiF6 ](2-) and [TiF6 ](2-) ), the N-donor organic ligand (pyrazine and 4,4'-bipyridine) and the metal ion (M=Co, Cu and Zn) is demonstrated here. This synthetic method allows them to be obtained in the form of spherical superstructures assembled from nanosized crystals...

Genetic mutations underlying neurodegenerative disorders impair ribosomal DNA (rDNA) transcription suggesting that nucleolar dysfunction could be a novel pathomechanism in polyglutamine diseases and in certain forms of amyotrophic lateral sclerosis/frontotemporal dementia. Here, we investigated nucleolar activity in pre-symptomatic digenic models of Parkinson's disease (PD) that model the multifactorial aetiology of this disease. To this end, we analysed a novel mouse model mildly overexpressing mutant human α-synuclein (hA53T-SNCA) in a PTEN-induced kinase 1 (PINK1/PARK6) knockout background and mutant mice lacking both DJ-1 (also known as PARK7) and PINK1...

The nucleolus is a stress sensor and compromised nucleolar activity may be considered as an attractive anticancer strategy. In the present study, the effects of three plant-derived natural compounds, i.e., sulforaphane (SFN), ursolic acid (UA) and betulinic acid (BA) on nucleolar state were investigated in breast cancer cell lines of different receptor status, namely MCF-7, MDA-MB-231 and SK-BR-3 cells. Cytostatic action of phytochemicals against breast cancer cells was observed at low micromolar concentration window (5-20µM) and mediated by elevated p21 levels, and cell proliferation of SFN-, UA- and BA-treated normal human mammary epithelial cells (HMEC) was unaffected...

Rekha Rai, Sandy Chang
Telomere dysfunctions, rendered through replicative attrition of telomeric DNA or due to the removal of shelterin components, are recognized as DNA double-stranded breaks (DSBs) by the DNA damage repair (DDR) pathway. This leads to the activation of DNA damage checkpoint sensors, including the Mre11-Rad50-Nbs1 (MRN) complex, γ-H2AX and 53BP1, the ATM and ATR signal-transducing kinases, and downstream effectors, including Chk1, Chk2, and p53. Robust DNA damage response signals at dysfunctional telomeres, achieved by the complete deletion of TRF2 or by expressing dominant-negative mutant TPP1ΔRD, can be detected by their association with γ-H2AX and 53BP1 forming "telomere dysfunction induced foci (TIFs)...

Tubulointerstitial fibrosis (TIF) is recognized as a final phenotypic manifestation in the transition from chronic kidney disease (CKD) to end-stage renal disease (ESRD). Here we show that conditional inactivation of Sav1 in the mouse renal epithelium resulted in upregulated expression of profibrotic genes and TIF. Loss of Sav1 induced Stat3 activation and a senescence-associated secretory phenotype (SASP) that coincided with the development of tubulointerstitial fibrosis. Treatment of mice with the YAP inhibitor verteporfin (VP) inhibited activation of genes associated with senescence, SASPs, and activation of Stat3 as well as impeded the development of fibrosis...

Klotho, an antiaging protein, can extend the lifespan and modulate cellular responses to inflammation and oxidative stress which can ameliorate chronic kidney diseases (CKD). To investigate the molecular mechanism of Klotho on inflammation in cyclosporine A (CsA) induced nephropathy, the mice were transfected with adenovirus mediated Klotho gene and treated with cyclosporine A (CsA; 30 mg/kg/day) for 4 weeks. Also, primary human renal proximal tubule epithelial cells (RPTECs) were treated with soluble Klotho protein and LPS...

Thickened infant formula (TIF) prepared with commercial xanthan gum (XG)-based food thickeners are commonly used to care for infants with swallowing difficulties or regurgitation. In this study, the rheological properties of TIF prepared with four commercial food thickeners (coded A-D) were determined as a function of thickener concentration, thickener type, and setting time because the selection of an appropriate food thickener for TIF preparation is necessary for managing dysphagia in infants. The flow and dynamic rheological properties of TIF were investigated at three different concentrations (1...

Leydig cells (LCs) in the adult testis have been identified as the major sites of oestrogen production, which is crucial for mammalian germ cell differentiation. Our previous work showed that transforming growth factor beta 1 (TGFB1) inhibits estradiol (E2) secretion via down-regulating Cyp19 gene expression in mature rat (LCs). However, the mechanism remains unclear. In the present study, the effects of TGFB1 on the expression levels of steroidogenic factor 1 (SF1), liver receptor homolog 1 (LRH1), cAMP response element-binding protein (CREB) and cAMP responsive element modulator (CREM) were evaluated by Western blotting and immunofluorescence staining both in primary cultured LCs and in rat testis...

Gene microarray and bioinformatic analysis showed that S100A8 was more abundant in the stroma surrounding tumor buddings (TBs) than in the stroma surrounding primary tumor cells in colorectal carcinomas. Here, S100A8(+) cells in 419 colorectal carcinoma samples were stained by immunohistochemistry and counted using Image-pro plus 6.0. TBs were also counted and biomarkers associated with the epithelial-mesenchymal transition and apoptosis were assessed by immunohistochemistry. We evaluated the association between S100A8(+) cells and clinico-pathological variables as well as survival...
