Many patients with locked-in syndrome (LIS) or complete locked-in syndrome (CLIS) also need brain-computer interface (BCI) platforms that do not rely on visual stimuli and are easy to use. We investigate command following and communication functions of mindBEAGLE with 9 LIS, 3 CLIS patients and three healthy controls. This tests were done with vibro-tactile stimulation with 2 or 3 stimulators (VT2 and VT3 mode) and with motor imagery (MI) paradigms. In VT2 the stimulators are fixed on the left and right wrist and the participant has the task to count the stimuli on the target hand in order to elicit a P300 response...

In simultaneous electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) studies, average reference (AR), and digitally linked mastoid (LM) are popular re-referencing techniques in event-related potential (ERP) analyses. However, they may introduce their own physiological signals and alter the EEG/ERP outcome. A reference electrode standardization technique (REST) that calculated a reference point at infinity was proposed to solve this problem. To confirm the advantage of REST in ERP analyses of synchronous EEG-fMRI studies, we compared the reference effect of AR, LM, and REST on task-related ERP results of a working memory task during an fMRI scan...

Interferon regulatory factor 5 (IRF5) plays a critical role in the induction of type I interferon, proinflammatory cytokines and chemokines, and participates in the pathogenesis of autoimmune diseases such as systemic lupus erythematosus (SLE). However, the relationship between IRF5 and childhood-onset SLE remains elusive. In the present study, we demonstrated that levels of mRNA expression of IRF5, IFN-α, and Sp1 were significantly increased in childhood-onset SLE, as seen on quantitative real-time PCR, and the expression of Sp1 and IFN-α was positively correlated with IRF5...

Recently we showed that 5% linseed oil (LSO) and 5% safflower oil (SFO) supplementation of cow's diets reduced milk fat yield by 30·38 and 32·42% respectively, accompanied by differential expression of genes and regulation by microRNAs (miRNA). This research communication addresses the hypothesis that epigenetic regulation could be involved in the observed milk fat reduction. Thus, this study investigated the gene expression pattern of major epigenetic modifying enzymes in response to dietary supplementation with LSO or SFO...

Rubinstein-Taybi syndrome (RSTS) is a rare genetic disorder in humans characterized by growth and psychomotor delay, abnormal gross anatomy, and mild to severe mental retardation (Rubinstein and Taybi, Am J Dis Child 105:588-608, 1963, Hennekam et al., Am J Med Genet Suppl 6:56-64, 1990). RSTS is caused by de novo mutations in epigenetics-associated genes, including the cAMP response element-binding protein (CREBBP), the gene-encoding protein referred to as CBP, and the EP300 gene, which encodes the p300 protein, a CBP homologue...

The PKR-like ER kinase (PERK) a transmembrane protein resides in the endoplasmic reticulum (ER) and activation of PERK serve as a key sensor of ER-stress which has been implicated in Traumatic Brain Injury (TBI). The loss of memory is one of the most common symptoms following TBI; however, the precise role of PERK activation in memory impairment after TBI has not been well elucidated. Here we have shown that blocking the activation of PERK using GSK2656157 prevents the loss of dendritic spines and rescues memory deficits following TBI...

BACKGROUND AND PURPOSE: The balance between T helper 17 (Th17) cells and regulatory T (Treg) cells, plays a critical role in rheumatoid arthritis (RA). The differentiation of Th17 cells requires the activation of STAT3, which determines the balance of Th17/Treg. Here, we investigated the therapeutic effect of Cryptotanshinone (CTS) on collagen induced mouse arthritis and explored the underlying mechanisms. EXPERIMENTAL APPROACH: Arthritis was induced in DBA/1 mice with bovine collagen type II and complete Freund's adjuvant...

Aims: Beyond the control of nuclear-cytoplasmic trafficking nucleoporins regulate gene expression and are involved in cardiac diseases. Notably, a number of cardiovascular disorders have been linked to alterations in epigenetic mechanisms. Here we aimed to determine the contribution of Nup153 to the epigenetic alterations occurring in cardiomyopathy of dystrophin-deficient mdx mice (C57BL/10ScSn-Dmd mdx /J). Methods and results: Nup153 was lysine-acetylated and its expression was significantly increased at protein level in mdx hearts compared with controls...

Reliable detection of error from electroencephalography (EEG) signals as feedback while performing a discrete target selection task across sessions and subjects has a huge scope in real-time rehabilitative application of Brain-computer Interfacing (BCI). Error Related Potentials (ErrP) are EEG signals which occur when the participant observes an erroneous feedback from the system. ErrP holds significance in such closed-loop system, as BCI is prone to error and we need an effective method of systematic error detection as feedback for correction...

INTRODUCTION: Recent advances regarding mechanisms of chronic pain emphasize the role of corticolimbic circuitry in predicting risk for chronic pain, independently from site of injury-related parameters. These results compel revisiting the role of peripheral nociceptive signaling in chronic pain. We address this issue by examining what brain circuitry transmit information regarding the intensity of chronic pain and how this information may be related to a common co-morbidity, depression...

BACKGROUND: Epigenome editing is expected to manipulate transcription and cell fates and to elucidate the gene expression mechanisms in various cell types. For functional epigenome editing, assessing the chromatin context-dependent activity of artificial epigenetic modifier is required. RESULTS: In this study, we applied clustered regularly interspaced short palindromic repeats (CRISPR)-dCas9-based epigenome editing to mouse primary T cells, focusing on the Forkhead box P3 (Foxp3) gene locus, a master transcription factor of regulatory T cells (Tregs)...

BACKGROUND: Cbp/P300-interacting transactivator with Glu/Asp-rich carboxy-terminal domain 2 (CITED2) is a pleiotropic protein associated with numerous cell functions, including transcription and differentiation. The role of CITED2 has been investigated in a number of malignancies; however, the roles of this protein in gastric cancers remain unclear. Therefore, we determined the role of CITED2 in gastric cancers. MATERIALS AND METHODS: Gastric cancer cell lines (MKN74, MKN28, 7901, and AGS) were used to assess CITED2 transcript levels...

Hematopoietic differentiation is controlled by key transcription factors, which regulate stem cell functions and differentiation. TAL1 is a central transcription factor for hematopoietic stem cell development in the embryo and for gene regulation during erythroid/megakaryocytic differentiation. Knowledge of the target genes controlled by a given transcription factor is important to understand its contribution to normal development and disease. To uncover direct target genes of TAL1 we used high affinity streptavidin/biotin-based chromatin precipitation (Strep-CP) followed by Strep-CP on ChIP analysis using ChIP promoter arrays...

Climate change has had a widespread impact on humans and natural systems. Heat stroke is a life-threatening condition in severe environments. The execution or inhibition of decision making is critical for survival in a hot environment. We hypothesized that, even with mild heat stress, not only executive processing, but also inhibitory processing may be impaired, and investigated the effectiveness of body cooling approaches on these processes using the Go/No-go task with electroencephalographic event-related potentials...

LIM-domain proteins, containing multiple cysteine-rich zinc finger-like motifs, have been shown to play diverse roles in several cellular processes. A common theme is that they mediate important protein-protein interactions that are key to their function. Androgen receptor-associated protein 55 (ARA55) belongs to this family of bridging proteins containing four C-terminal LIM domains. It has a dual role with functions both at focal adhesions and in the nucleus, apparently shuttling between the two compartments...

Reports an error in "Treating adult survivors of childhood emotional abuse and neglect: A new framework" by Frances K. Grossman, Joseph Spinazzola, Marla Zucker and Elizabeth Hopper (American Journal of Orthopsychiatry, 2017, Vol 87[1], 86-93). In the article, in the second sentence of the third paragraph of the "The Empirical Base for CBP" section, "construction of a life narrative" should have read "construction of a trauma narrative." The full corrected sentence follows: "Therefore, the trauma treatment component traditionally focused upon construction of a trauma narrative must be expanded to address the effects of trauma on our clients' entire life narratives, including their development of a sense of self and social identity...
