Ronen Hershman, Avishai Henik, Noga Cohen
Pupillometry (or the measurement of pupil size) is commonly used as an index of cognitive load and arousal. Pupil size data are recorded using eyetracking devices that provide an output containing pupil size at various points in time. During blinks the eyetracking device loses track of the pupil, resulting in missing values in the output file. The missing-sample time window is preceded and followed by a sharp change in the recorded pupil size, due to the opening and closing of the eyelids. This eyelid signal can create artificial effects if it is not removed from the data...

Oral submucous fibrosis (OSF) is a precancerous condition with symptoms of limited mouth opening and areca nut chewing habit has been implicated in its pathogenesis. Hinokitiol, a natural tropolone derived from Chamacyparis taiwanensis, has been reported to improve oral lichen planus and inhibit various cancer cells. Here, we showed that hinokitiol reduced the myofibroblast activities in fBMFs and prevented the arecoline-induced transdifferentiation. Treatment of hinokitiol dose-dependently downregulated the myofibroblast markers as well as various EMT transcriptional factors...

Appropriate exposure to Posaconazole (PSZ) was limited since the recent approval of the delayed release oral tablet formulation. Our goal was to determine the exposure obtained by using the standard dose of 300mgx1 in lung transplant patients (LT) including cystic fibrosis (CF) background.PSZ trough concentrations (C0) were determined using LCMS assay. Indicative thresholds of interest were <0.7mg/L (prophylaxis) and 1-3mg/L (curative). Tacrolimus (TRL) and everolimus (ERL) C0 measured during PSZ exposure were collected...

Across Europe, Roma face exclusion and obstacles in access to health services, resulting in poorer health. While there are legal and policy frameworks for Roma inclusion, implementation often lags behind. Increasing the grassroots capacity of Roma to advocate for accountability in health care and against systemic impediments has been a central focus of Open Society Foundations (OSF) support. This analysis discusses the impact of an OSF-supported legal advocacy project on Roma health rights in Macedonia. The paper uses qualitative indicators to measure the capacity of nongovernmental organizations, accountability for violations, changes in law and practice, and impact on communities...

BACKGROUND/PURPOSE: Emerging research findings suggest that long non-coding RNAs (lncRNAs) are key regulators to fibrosis formation. Nevertheless, the role of lncRNA GAS5-AS1 in the progression of precancerous oral submucous fibrosis (OSF) remains to be elucidated. METHODS: Quantitative real-time PCR were used to examine the expression of GAS5-AS1 in OSF tissues. The activities of myofibroblasts, including collagen contractility and cell migration, as well as the marker α-smooth muscle actin (SMA) were assessed following overexpression of GAS5-AS1...

About 7000 rare, or orphan, diseases affect more than 350 million people worldwide. Although these conditions collectively pose significant health care problems, drug companies seldom develop drugs for orphan diseases due to extremely limited individual markets. Consequently, developing new treatments for often life-threatening orphan diseases is primarily contingent on financial incentives from governments, special research grants, and private philanthropy. Computer-aided drug repositioning is a cheaper and faster alternative to traditional drug discovery offering a promising venue for orphan drug research...

BACKGROUND: STRO-1 is a mesenchymal cell marker present on all clonogenic stromal precursors. Current evidence has indicated that the pathogenesis of fibrotic changes may be mediated by stemness properties. The aim of this study was to investigate the role of STRO-1 in areca quid chewing-associated oral submucous fibrosis (OSF). METHODS: Thirty OSF specimens and ten normal buccal mucosa were examined by immunohistochemistry. The activity of STRO-1 from fibroblasts cultured from normal buccal mucosa (BMFs) and OSF (OSFFs) were measureed and the effects of arecoline, a major areca nut alkaloid, on STRO-1 in BMFs...

Oral Submucous Fibrosis (OSF), is a well-recognized, oral potentially malignant disorder predominantly affecting the South- Asian countries. OSF causes unique generalized fibrosis of the submucosal oral soft tissues, resulting in marked rigidity of the oral mucosa leading to progressive inability to open the mouth, rigidity of lips and difficulty in protruding the tongue. In this review we have discussed the multifactorial etiology of this potentially malignant disorder, including Chillies, Nutritional Deficiencies, Inducible nitric oxide synthsis (iNOS), genetic and immunological predisposition; and most importantly the role of areca nut and the effect of copper content in it...

We demonstrate the use of three popular Bayesian software packages that enable researchers to estimate parameters in a broad class of models that are commonly used in psychological research. We focus on WinBUGS, JAGS, and Stan, and show how they can be interfaced from R and MATLAB. We illustrate the use of the packages through two fully worked examples; the examples involve a simple univariate linear regression and fitting a multinomial processing tree model to data from a classic false-memory experiment. We conclude with a comparison of the strengths and weaknesses of the packages...

Apart from product yield and titer, volumetric productivity is a key performance indicator for many biotechnological processes. Due to the inherent trade-off between the production of biomass as catalyst and of the actual target product, yield and volumetric productivity cannot be optimized simultaneously. Therefore, in combination with genetic techniques for dynamic regulation of metabolic fluxes, two-stage fermentations (TSFs) with separated growth and production phase have recently gained much interest because of their potential to improve the productivity of bioprocesses while still allowing high product yields...

Oral submucous fibrosis (OSF) has been recognized as one of the oral potentially malignant disorders. Areca nut chewing is implicated in this pathological fibrosis, and it causes chronic inflammation and persistent activation of myofibroblasts. As yet, existing treatments only provide temporary symptomatic relief and there is a lack of an effective intervention to cure OSF. Therefore, development of approaches to ameliorate myofibroblast activities becomes a crucial objective to prevent the malignant progression of OSF...

Fibrosis, which can be defined as an abnormal or excessive accumulation of extracellular matrix (ECM), particularly fibrillar collagens, is a key driver of progressive organ dysfunction in many inflammatory and metabolic diseases, including idiopathic pulmonary fibrosis (IPF), cirrhosis, nephropathy, and oral submucous fibrosis (OSF). It has been estimated to contribute to ∼45% of deaths in the developed world. Therefore, agents that target specific fibrotic pathways, with the consequence of slowing, arresting, or even reversing the progression of tissue fibrogenesis, are urgently needed...

Oral submucous fibrosis (OSF) has been indicated as one of the oral potentially malignant disorders. Epidemiological studies have attributed this pathological fibrosis to the habit of areca nuts chewing, which causes chronic inflammation and persistent activation of myofibroblasts in the oral cavity. Hence, it is crucial to find an effective intervention to ameliorate inflammation in order to prevent the malignant progression of OSF. In this study, we assessed the anti-inflammatory effect of the immunomodulatory protein, GMI, extracted from Ganoderma microsporum on the expression proinflammatory cytokines and the myofibroblast characteristics in human fibrotic buccal mucosal fibroblasts (fBMFs)...

Periostin (POSTN, PN, or osteoblast-specific factor OSF-2) is a multifunctional cytokine that signals between the cell and the extracellular matrix. Periostin plays an important role in tumor development and is involved in carcinoma cell epithelial-mesenchymal transition (EMT), whereby mature epithelial cells undergo phenotypic morphological changes and become invasive, motile cells. Here, we discuss the molecular mechanisms involved in periostin-induced promotion of EMT in lung cancer cells. Online TCGA datasets demonstrate the prognostic relevance of periostin in lung cancer; a higher periostin level correlates with poor overall survival...

OBJECTIVE: Changes in the DSM-5 eating disorders criteria sought to increase the clarity of the diagnostic categories and to decrease the preponderance of nonspecified eating disorders. The first objective of this study was to analyze how these revisions affect threshold and EDNOS/OSFED eating disorder diagnoses in terms of prevalence, sex ratios, and diagnostic distribution in a student sample. Second, we aimed to compare the impairment levels of participants with a threshold, an EDNOS/OSFED and no diagnosis using both DSM-IV and DSM-5...
