Unfolded protein response (UPR) has roles not only in resolving the accumulation of unfolded proteins owing to endoplasmic reticulum (ER) stress, but also in regulation of cellular physiological functions. ER stress transducers providing the branches of UPR signaling are known to localize in distal dendritic ER of neurons. These reports suggest that local activation of UPR branches may produce integrated outputs for distant communication, and allow regulation of local events in highly polarized neurons. Here, we demonstrated that synaptic activity- and brain-derived neurotrophic factor (BDNF)-dependent local activation of UPR signaling could be associated with dendritic functions through retrograde signal propagation by using murine neuroblastoma cell line, Neuro-2A and primary cultured hippocampal neurons derived from postnatal day 0 litter C57BL/6 mice...

Endocannabinoid pharmacology is now relatively well understood with a number of endocannabinoids and endogenous cannabinoid neurotransmitters identified and the pharmacokinetics relatively well ascertained. Further, the cannabinoid receptors are now molecularly and pharmacologically characterised and the cell processes involved in endocannabinoid transcription, synthesis, post-translational modification and protein expression are reported. Endogenous cannabinoids have been shown to have key roles in immune and pain pathways and neuro-behavioural signalling including appetite regulation...

Psychologists usually considered the "Self" as an object of experience appearing when the individual perceives its existence within the conscious field. In accordance with such a view, the self-representing capacity of the human mind has been related to corticolimbic learning processes taking place within individual development. On the other hand, Carl Gustav Jung considered the Self as the core of our personality, in its conscious and unconscious aspects, as well as in its actual and potential forms. According to Jung, the Self originates from an inborn dynamic structure integrating the essential drives of our "brain-mind," and leading both to instinctual behavioral actions and to archetypal psychological experiences...

Receptor (i.e genomic) and non-receptor (or non-genomic) effects of endocrine toxicology have received limited or almost non-existent attention for tropical species and regions. In the present study, we have studied the effects of di-(2-ethylhexyl) phthalate (DEHP) on neuro- and interrenal steroidogenesis of the African catfish (Clarias gariepinus) using molecular, immunochemical and physiological approaches. Juvenile fish (mean weight and length: 5.6 ± 0.6g and 8.2 ± 1.2 cm, respectively), were randomly distributed into ten 120 L rectangular glass tanks containing 60 L of dechlorinated tap water, at 50 fish per exposure group...

It is a challenge to evaluate and treat the patients with disorders of consciousness (DOC) in the clinic. Due to the huge costs of prolonged intensive care, the management of these patients raises great financial strain on families and important ethical questions. To date, several studies have attempted to specifically detect pharmacologic or non-pharmacologic effectiveness, until now there were no evidence-based guidelines about the treatment of patients with DOC. Recently, because of ethical and procedural limitations on the use of invasive stimulation techniques, non-invasive brain stimulation, such as the transcranial direct current stimulation (tDCS), has been investigated for improving the level of consciousness in patients with DOC...

Diacylglycerol kinase (DGK) phosphorylates diacylglycerol (DG) to produce phosphatidic acid (PA). Mammalian DGK comprises ten isozymes (α-κ) and regulates a wide variety of physiological and pathological events, such as cancer, type II diabetes, neuronal disorders and immune responses. DG and PA consist of various molecular species that have different acyl chains at the sn-1 and sn-2 positions, and consequently, mammalian cells contain at least 50 structurally distinct DG/PA species. Because DGK is one of the components of phosphatidylinositol (PI) turnover, the generally accepted dogma is that all DGK isozymes utilize 18:0/20:4-DG derived from PI turnover...

Growing evidence indicates that endoplasmic reticulum (ER) stress and/or ER stress-mediated apoptosis may play a role in the pathogenesis of neurodegenerative diseases such as Alzheimer's disease. The present study investigated the effects of non-cytotoxic concentrations of nitric oxide (NO) and nitrite, a metabolite of NO, on ER stress and ER stress-mediated apoptosis in Neuro-2a cells exposed to homocysteine (Hcy), an endogenous ER stress inducer. Hcy induced ER stress, as confirmed by inositol-requiring enzyme 1α (IRE1α) phosphorylation and X-box-binding protein-1 (Xbp1) mRNA splicing as well as C/EBP homologous protein (CHOP) expression, and apoptosis, as verified by Annexin V-positive cells...

Thyroid hormones (TH or T3) and their DNA binding nuclear receptors (TRs), direct transcriptional regulation in diverse ways depending on the host cell environment and specific promoter characteristics of TH sensitive genes. This study sought to elucidate the impact on transcriptional repression of nucleotide sequence/orientation within TR binding sites, TR elements, (TREs) of TH sensitive promoters, to better understand ligand dependent transcriptional repression of wild-type promoters. Computational analysis of the HSV-1 thymidine kinase (TK) gene TRE bound by TR and RXR revealed a single TRE point mutation sufficient to reverse the TRE orientation...

Previous studies have shown that deficits in social cognition mediate the association between neuro-cognition and functional outcome. Based on these findings, the current study presents an examination of the mediating role of social cognition and includes two different outcomes: social functioning assessed by objective observer and social quality of life assessed by subjective self-report. Instruments measuring different aspects of social cognition, cognitive ability, social functioning and social quality of life were administered to 131 participants who had a diagnosis of a serious mental illness...

Epidemiological studies have shown the adverse neuro-behavioral health effects of lead exposure among children, in particular. However, there is lack evidence in this regard from developing countries. The main aim of this study was to assess the association between blood lead levels (BLLs) during early adolescence and violent behavior in late adolescence. Our study sample from the Birth to Twenty Plus cohort in Soweto-Johannesburg, South Africa included 1332 study participants (684 females). BLLs were measured using blood samples collected at age 13years...

Regional plexus and nerve blocks are a common technique in modern anesthesia. Since ultrasound machines are available in many departments, the role of nerve stimulation is highly discussed and different approaches to perform the blocks are taken into account. Common technique for electrical nerve stimulation is searching for a stimulating threshold of 0.4-0.5mA using an impulse width of 0.1ms. We present our hypothesis of using all possible information with a new concept of protective nerve stimulation together with first data supporting our theory...

BACKGROUND: Neuroimmune interactions play a vital role in many of the most common pain conditions, such as arthritis. There have been many attempts to derive clinically predictive information from an individual's inflammatory response in order to gauge subsequent pain perception. OBJECTIVES: Here, we wanted to test whether this effort could be enhanced and complemented by the use of a model system which takes into account the function of not just circulating, but also tissue-resident immune cells: ultraviolet B (UVB) irradiation of the skin...

Patient-reported outcomes (PROs) are playing an increasing role in multiple sclerosis (MS) research and practice, and are essential for understanding the effects that MS and MS treatments have on patients' lives. PROs are captured directly from patients and include symptoms, function, health status, and health-related quality of life. In this article, we review different categories (e.g., generic, targeted, preference-based) of PRO measures and considerations in selecting a measure. The PROs included in MS clinical research have evolved over time, as have the measures used to assess them...

Many essential gastrointestinal functions, including motility, secretion and blood flow are regulated by the autonomic nervous system (ANS), both through intrinsic enteric neurons and extrinsic (sympathetic and parasympathetic) innervation. Recently identified neuro-immune mechanisms, in particular the interplay between enteric neurons and muscularis macrophages, are now considered to be essential for fine-tuning peristalsis. These findings shed new light on how intestinal immune cells can support enteric nervous function...
