STIM1 is an endoplasmic reticulum calcium sensor that is involved in several processes in neurons, including store-operated calcium entry. STIM1 also inhibits voltage-gated calcium channels, such as Cav1.2 and Cav3.1, and is thus considered a multifunctional protein. The aim of this work was to investigate the ways in which transgenic neuronal overexpression of STIM1 in FVB/NJ mice affects animal behavior and the electrophysiological properties of neurons in acute hippocampal slices. We overexpressed STIM1 from the Thy1...

The efficacy of treatment for intravenous elemental mercury intoxication has not been fully studied with regard to clinical outcomes, and treatment recommendations vary. We treated a 41-year-old man with a history of drug abuse and depression who attempted suicide using 1 mL (13.53 g) metallic Hg i.v. He was admitted to the hospital two months later for dyspnoea and thoracic pain and was diagnosed with pneumonia. Hg deposits were seen in the lungs and extra-pulmonary organs. His blood level (372 μg/L) exceeded the population level of 5 μg/L by more than 70-fold...

OBJECTIVE: Depression is known to negatively impact social functioning, with patients commonly reporting difficulties maintaining social relationships. Moreover, a large body of evidence suggests poor social functioning is not only present in depression but that social functioning is an important factor in illness course and outcome. In addition, good social relationships can play a protective role against the onset of depressive symptoms, particularly in late-life depression. However, the majority of research in this area has employed self-report measures of social function...

Several lines of research support the hypothesis that migraine is a spectrum of illness, with clinical symptoms that vary along a continuum from episodic migraine to chronic migraine. Physiologic changes may result in episodic migraine evolving into chronic migraine over months to years in susceptible individuals. With chronification, headache frequency increases, becoming more disabling and less responsive to therapy. Neurophysiologic and functional imaging research has reported that chronic migraine may be associated with severity-specific metabolic, functional, and structural abnormalities in the brainstem...

Distinct populations of D1- and D2-dopamine receptor expressing medium spiny neurons (D1-/D2-MSNs) comprise the nucleus accumbens, and activity in D1-MSNs promotes, while activity in D2-MSNs inhibits motivated behaviors. We used chemogenetics to extend D1-/D2-MSN cell specific regulation to cue-reinstated cocaine seeking in a mouse model of self-administration and relapse, and found that either increasing activity in D1-MSNs or decreasing activity in D2-MSNs augmented cue-induced reinstatement. Both D1- and D2-MSNs provide substantial GABAergic innervation to the ventral pallidum, and chemogenetic inhibition of ventral pallidal neurons blocked the augmented reinstatement elicited by chemogenetic regulation of either D1- or D2-MSNs...

Neurotoxins are harmful to nervous system and cause either neuronal cell death or impairment of synaptic activity, which contributes to Parkinson's disease or other neuronal disorders. Hippocampal synaptic plasticity was proposed as a cellular model for memory processing. In this study, we reported a novel effect of neurotoxin, 1-methyl-4-phenylpyridinium (MPP(+)), on metabotropic glutamate receptor 1/5 agonist, 3,5-dihydroxyphenylglycine (DHPG)-induced hippocampal synaptic plasticity, and MPP(+) incubation blocked DHPG-induced hippocampal long-term depression (LTD) in Schaffer collateral-CA1 synapses...

BACKGROUND: Mental disorders are the most common health problems in the worldwide population. Current medicines against these conditions have undesired side effects or limited effectiveness. These disadvantageous pharmacological and therapeutic characteristics provoke a low adherence to treatment in an important percentage of patients with mental disorders. Since ancient times, ethnically different groups have been using plants extracts as medicines for the treatment of mental conditions including dementia, depression and anxiety disorders...

BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare disease characterised by a severe impairment of functional status and quality of life (QoL). Use of rehabilitative programmes may help to improve outcomes. The aim of this pre/post test case series was to evaluate the impact of a training program, including sessions of aerobic and resistance exercise, inspiratory muscle reinforcement, slow breathing, relaxation, and psychological support, on functional outcomes. METHODS: Fifteen patients affected by PAH, in World Health Organization (WHO) Functional Class (FC) II or III and in stable clinical condition, were included in a 4-week cardiorespiratory training programme conducted in outpatient service...

BACKGROUND: Multiple case definitions are in use to identify chronic fatigue syndrome (CFS). Even when using the same definition, methods used to apply definitional criteria may affect results. The Centers for Disease Control and Prevention (CDC) conducted two population-based studies estimating CFS prevalence using the 1994 case definition; one relied on direct questions for criteria of fatigue, functional impairment and symptoms (1997 Wichita; Method 1), and the other used subscale score thresholds of standardized questionnaires for criteria (2004 Georgia; Method 2)...

REVIEW
F Ulrich, F Petermann
In recent decades, the understanding of the short and longer term effects of health-damaging behaviors and mental health problems in pregnant women and the underlying mechanisms of these behaviors and illnesses has significantly increased. In contrast, little is known about the factors affecting individual pregnant women which contribute to health-damaging behaviors and mental illness. The aim of this paper was therefore to summarize the current state of research into the consequences of nicotine and alcohol consumption, malnutrition, excessive weight gain or obesity, and impaired mental health (depression and anxiety) during pregnancy...

BACKGROUND: Researchers have attempted to operationalise objective measures of cognitive fatigability in multiple sclerosis (MS) to overcome the perceived subjectivity of patient-reported outcomes of fatigue (PROs). Measures of cognitive fatigability examine decrements in performance during sustained neurocognitive tasks. OBJECTIVE: This personal viewpoint briefly summarises available evidence for measures of cognitive fatigability in MS and considers their overall utility...

BACKGROUND: The degree of overlap between schizophrenia (SCZ) and affective psychosis (AFF) has been a recurring question since Kraepelin's subdivision of the major psychoses. Studying nonpsychotic relatives allows a comparison of disorder-associated phenotypes, without potential confounds that can obscure distinctive features of the disorder. Because attention and working memory have been proposed as potential endophenotypes for SCZ and AFF, we compared these cognitive features in individuals at familial high-risk (FHR) for the disorders...

Findings considering conditioned pain modulation (CPM) in chronic back pain (CBP) are contradictory. This might be because many CBP patients report pain in further areas of the body and altered CPM might influence spatial extent of pain rather than CBP per se. Therefore, we compared CPM in CBP patients with different pain extent. Fibromyalgia syndrome (FMS) patients, for whom CPM-impairment is reported most consistently, were measured for comparison.Based on clinical evaluation and pain-drawings patients were categorized into chronic local back pain (CLP; n=53), chronic widespread back pain (CWP; n=32), and FMS (n=92)...

OBJECTIVE: Mitochondrial dysfunction and energy metabolism impairment are key components in the pathophysiology of bipolar disorder (BD) and may involve a shift from aerobic to anaerobic metabolism. Measurement of brain lactate in vivo using proton magnetic resonance spectroscopy (H-MRS) represents an important tool to evaluate mitochondrial and metabolic dysfunction during mood episodes, as well as to monitor treatment response. To date, very few studies have quantified brain lactate in BD...
