OBJECTIVE: In this study, we hypothesized that in the absence of oral hygiene, re-growth of the climax microbial communities of supra and subgingival biofilm happens in a faster and more intense fashion in individuals with chronic periodontitis (CP) compared to periodontally healthy controls (PH). DESIGN: Thirty patients (PH=15 and CP=15) received professional supragingival prophylaxis, and were asked to refrain from oral hygiene for 7days. Supra and subgingival biofilm samples and GCF were collected from randomly selected quadrants at baseline (before prophylaxis), immediately after prophylaxis, 2h, 6h, 24h, and 7days after prophylaxis...

Oxidative potential (OP) of particulate matter (PM) is proposed as a biologically-relevant exposure metric for studies of air pollution and health. We aimed to evaluate the spatial variability of the OP of measured PM2.5 using ascorbate (AA) and (reduced) glutathione (GSH), and develop land use regression (LUR) models to explain this spatial variability. We estimated annual average values (m(-3)) of OP(AA) and OP(GSH) for five areas (Basel, CH; Catalonia, ES; London-Oxford, UK (no OP(GSH)); the Netherlands; and Turin, IT) using PM2...

More and more researches have shown the vital functions of long non-coding RNAs (LncRNAs) in modulating the biological progresses in tumorigenesis. OR3A4 is such a type of lncRNA. The long non-coding RNA (lncRNA) OR3A4 has recently been exposed to be exceptionally expressed and referred to the development of several cancers. Nevertheless, the biological function and clinical significance of OR3A4 in the carcinogenesis of breast cancer (BC) are still blurry. Therefore, we carried out the following study to make sure the underlying functions of OR3A4 in breast cancer...

PURPOSE: The prevalence of epilepsy among patients with multiple sclerosis (MS) has been found higher than in the general population. Although cortical pathology may be involved, the causal link between MS and epileptic seizures is still unclear. We aimed to identify and describe the patients with active epilepsy in a previously described population based MS-cohort. METHODS: Medical records of all patients with MS in Nordland County on January 1, 2010, were scrutinizing for evidence of comorbid seizures and epilepsy...

BACKGROUND: Family dysfunction has been proposed as one of the environmental mechanisms whereby risk of depression is transmitted from mothers to their children. Using our sample of offspring at high and low familial risk for depression, we hypothesized that: a) high-risk offspring (n = 79) and their mothers will report more extensive family dysfunction than low-risk offspring (n = 82) and their mothers, b) family dysfunction will predict the extent of offspring's depressive symptoms, and c) family dysfunction will mediate the impact of mother's depression on offspring's depressive symptoms...

BACKGROUND: It has been claimed that the quality of a diet is associated with the incidence of depressive disorders. We sought to investigate the evidence for this claim. METHODS: Systematic searches were performed up to March 6th, 2017 in order to identify prospective cohort studies that reported on exposure to dietary patterns or food groups and the incidence of depression/depressive symptoms. Data from 24 independent cohorts (totalling 1,959,217 person-years) were pooled in random-effects meta-analyses...

BACKGROUND: Several studies have linked childhood hunger to an increased risk for later depression. However, as yet, there has been little research on this relation in adults of all ages or whether there are sex differences in this association. The current study examined these issues using data from a national population-based sample. METHODS: Data were analyzed from 5095 adults aged 25-84 collected during the Estonian Health Interview Survey 2006. Information was obtained on the frequency of going to bed hungry in childhood and on depressive symptoms using the Emotional State Questionnaire (EST-Q)...

INTRODUCTION: Gastric lipomas are unusual benign lesions and account for less than 1% of all tumours of the stomach and 5% of all gastrointestinal lipomas (Thompson et al.2003; Fernandez et al. 1983 [1,2]). Although predominantly asymptomatic and indolent; they may present with gastric outlet obstruction and upper gastrointestinal (GI) bleeding owing to size and ulceration. Only a few cases have been reported, presenting large in size with massive GI bleeding (Alcalde Escribano et al...

For entry, Ebola virus (EBOV) requires the interaction of its viral glycoprotein with the cellular protein Niemann-Pick C1 (NPC1) which resides in late endosomes and lysosomes. How EBOV is trafficked and delivered to NPC1 and whether this is positively regulated during entry remain unclear. Here, we show that the PIKfyve-ArPIKfyve-Sac3 cellular complex, which is involved in the metabolism of phosphatidylinositol (3,5) bisphosphate (PtdIns(3,5)P2), is critical for EBOV infection. Although the expression of all subunits of the complex was required for efficient entry, PIKfyve kinase activity was specifically critical for entry by all pathogenic filoviruses...

Used Latex gloves found at crime scenes can provide strong evidence against a suspect as they almost certainly contain both the fingermarks and DNA of the perpetrator who had worn them. However, over the years, Latex gloves have proved to be a rather difficult substrate for fingermarks development, with most of the standard techniques producing poor results. In this study, the two main protocols for development on either porous or non-porous surfaces: Ninhydrin-HFE and superglue fuming followed by crystal violet (CV) dyeing, respectively, had been examined on 100 disposable Latex gloves from twenty five donors...
