REVIEW
Fotini N Skopouli, Stergios Katsiougiannis
A large body of clinical evidence on the association between stressful life events and autoimmune diseases suggests that stress may play an important role in the pathogenesis of these disorders. In this article, we discuss the effects of stress, not on the immune system but on specific cell populations against which the autoimmune reactivity is directed. Using Sjögren's syndrome as a model autoimmune disease, we review the role of stress in the initiation and perpetuation of autoimmune reactivity. We present data that reveal the effects of stress on salivary gland epithelial cells, suggesting that stress can become immunogenic through its various effects on salivary gland epithelium...

BACKGROUND: Demands for the production of legible handwriting produced in a timely manner increase as children progress through school. Despite the considerable number of children faced with handwriting difficulties, there is no quick and practical tool to assess legibility in this population. AIM: The aim of this study was to develop the Handwriting Legibility Scale (HLS) and to establish the scale's reliability and validity. METHODS: The HLS is a non-language dependent scale which assesses global legibility, based on five criteria applied to samples of 'free writing'...

After 2010, panic disorders became relatively common in South Korea, with many celebrities confessing to the public that they have panic disorder. The annual number of patients with panic disorder and sleep disorder have been gradually increasing. In light of these increases, we analyzed the relationship between sleep disorder and panic disorder. We used national claim data to design a 1:3 nested case-control study. The study included medical claims filed for 29,312 patients during 2004-2013. We performed conditional logistic regression analysis to investigate the relationship between sleep disorder and panic disorder...

Problems related to the capacity to successfully engage response inhibition are considered a risk factor for the development of substance use disorders (SUDs), but the evidence has been predominantly cross-sectional. In this commentary, we argue that recent longitudinal studies with multi-modal measures of response inhibition can improve understanding of how response inhibition may intersect with substance use among adolescents. Most Stop-Signal studies suggest that slower response inhibition predicts substance use progressions, with one multi-site study showing greater fronto-parietal activity indicative of risk...

The health benefits of regular physical activity are substantial and well-established. However, population activity levels are insufficient to obtain health benefits in the United Kingdom (UK), and strategies to increase activity, particularly in income-deprived communities, are sought. Socioecological models of physical activity posit that activity levels are influenced by social, physical and wider environmental factors. In line with a growing evidence base, there is a need to understand the factors that contribute to an activity-supportive neighbourhood within deprived settings within the UK...

OBJECTIVE: Medically unexplained physical symptoms (MUPS) are commonly seen across health care settings. Earlier studies have focussed on prevalence, cost-utilization and burden. Data from India is scarce. Patients with persistent MUPS have more impairment and psychological distress. This study was designed to assess psychological morbidity, health anxiety (HA), somatic symptom load, disability, quality of life (QOL) in patients with persistent MUPS presenting to a general medical outpatient service and compare it with patients with medically explained physical symptoms (MEPS)...

REVIEW
Dimitri Renard
Cerebral microbleeds (CMB) are small foci of (acute, subacute, or chronic) blood products, best seen using MRI techniques sensitive to iron deposits (i.e. gradient-echo T2*-weighted and susceptibility-weighted imaging), frequently encountered in small vessel disease (SVD, with hypertensive vasculopathy and cerebral amyloid angiopathy as most frequent conditions) and also in other disorders. In this review, we will mainly discuss the MRI characteristics of CMB and the associated MRI abnormalities encountered in common and less common SVD and non-SVD conditions...

Light localization is a phenomenon which arises due to the interference effects of light waves inside a disordered optical medium. Quantification of degree light localization in optical media is widely used for characterizing degree of structural disorder in that media. Recently, this light localization approach was extended to analyze structural changes in biological cell like heterogeneous optical media, with potential application in cancer diagnostics. Confocal fluorescence microscopy was used to construct 'optical lattices', which represents 2D refractive index map corresponding to the spatial mass density distribution of a selected molecule inside the cell...

BACKGROUND: This study examined whether combining naltrexone (NTX) with bupropion (BUP) is more effective in reducing alcohol drinking in alcohol-preferring (P) rats with a genetic predisposition toward high voluntary alcohol intake than is either drug alone. METHODS: Alcohol-experienced, adult, male, alcohol-preferring (P) rats were fed NTX alone in a dose of 10.0 mg/kg BW, BUP alone in a dose of 10.0 mg/kg BW, BUP alone in a dose of 20.0 mg/kg BW, NTX (10.0 mg/kg BW) + BUP (10...

BACKGROUND: Epigenetic mechanisms are candidate moderators of the effect of maltreatment on brain and behavior. Interactions between maltreatment and the Monoamine Oxidase A upstream variable number tandem repeat genotype (MAOA-uVNTR) are associated with alcohol-related problems. However, presently it is not known whether DNA methylation moderates this association. The study focused on fifty-three young adult males and aimed to determine: whether MAOA methylation moderated the association of alcohol-related problems with the interaction of MAOA-uVNTR and maltreatment; and whether alcohol consumption moderated the association of MAOA methylation with the interaction of MAOA-uVNTR and maltreatment...

It is well known that sleep disorders are harmful to people's health and performance, and growing evidence suggests that sleep deprivation (SD) can trigger neuroinflammation in the brain. The nucleotide-binding domain and leucine-rich repeat protein-3 (NLRP3) inflammasome is reported to be relevant to the neuroinflammation induced by SD, but the regulatory signaling that governs the NLRP3 inflammasome in SD is still unknown. Meanwhile, whether the regulatory action of antidepressants in astrocytes could affect the neuroinflammation induced by SD also remains obscure...

BACKGROUND: Mental imagery has a more powerful impact on our emotions than thinking in words about the same material. Treating intrusive images with imagery rescripting (IR) has been reported for various disorders, including post-traumatic stress disorder, social anxiety disorder, and bipolar disorder. There has been less research about IR as a major depressive disorder (MDD). AIMS: We examined whether IR without focusing on early traumatic memories is effective in MDD...

Ataxias are locomotor disorders that can have an origin both neural and muscular, although both impairments are related. Unfortunately, ataxia has no cure and the current therapies are aimed at motor re-education or muscular reinforcement. Nevertheless, cell therapy is becoming a promising approach to deal with incurable neural diseases, including neuro-muscular ataxias. Here we have used a model of ataxia, the PCD mutant mouse, to study the effect of healthy (wild-type) bone marrow transplantation on the restoration of defective mobility...

Nanoscience provides us with new opportunities to develop nanotechnologies for treating, in particular, central nervous system disorders such as Alzheimer disease and multiple sclerosis. From a methodological point of view, it is challenging to deliver drugs effectively across the blood-brain barrier and blood-cerebrospinal fluid barrier. Our 10-year data and reports from both in vivo and in vitro studies, however, have consistently proved that therapeutic drugs of different types can be generally loaded in/on the nanocarriers for targeted and programmable deliveries to the central nervous system with a high degree of efficacy...

Glial cell activation plays an important role in the pathogenesis of various neurodegenerative disorders. This article presents a protocol for the preparation of cultures consisting of rat embryonic cortical neurons grown in the presence of cortical microglia, in which the glia are present in physical contact with the neurons or separated by a semipermeable membrane barrier. An example of how such systems can be used to evaluate potential neuroprotective agents will also be described.

The American Academy of Pediatrics published attention deficit hyperactivity disorder (ADHD) guidelines, but significant variability exists in care. This exploratory study aimed to understand barriers to compliance with primary care office contacts for ADHD medication management. The study was conducted at a single academic medical center via retrospective chart review between 6/1/15 and 5/31/16 in combination with telephone interviews. Participants included 306 children 6-12 years old with an ADHD-related ICD-9/ICD-10 diagnosis...

We compare the information transmission of a time-dependent signal by two types of uncoupled neuron populations that differ in their sources of variability: i) a homogeneous population whose units receive independent noise and ii) a deterministic heterogeneous population, where each unit exhibits a different baseline firing rate ('disorder'). Our criterion for making both sources of variability quantitatively comparable is that the interspike-interval distributions are identical for both systems. Numerical simulations using leaky integrate-and-fire neurons unveil that a non-zero amount of both noise or disorder maximizes the encoding efficiency of the homogeneous and heterogeneous system, respectively, as a particular case of suprathreshold stochastic resonance...
