Long noncoding RNA as an indicator differentiating schizophrenia from major depressive disorder and generalized anxiety disorder in nonpsychiatric hospital

16-Jan-2017 | Xuelian Cui; Wei Niu; Lingming Kong; Mingjun He; Kunhong Jiang; Shengdong Chen; Aifang Zhong; Qiaoli Zhang; Wanshuai ..., Biomarkers in Medicine, 2017

Aim: Depression and anxiety are common symptoms for schizophrenia (SZ) in the early onset. This study aimed to determine whether long noncoding RNAs (lncRNAs) can be indicators for diagnosing SZ in nonpsychiatric hospitals. Materials & methods: Three upregulated SZ lncRNAs, six downregulated ...

Netrin G1: its downregulation in the nucleus accumbens of cocaine‐conditioned mice and genetic association in human cocaine dependence

11-Jan-2017 | Sabah Kelaï, Nicolas Ramoz, Jean‐Marie Moalic, Florence Noble, Naguib Mechawar, Sandrine Imbeaud, Gustavo Turecki, M ..., Addiction Biology, 2017

Abstract Netrin G1 is a presynaptic ligand involved in axonal projection. Although molecular mechanisms underlying cocaine addiction are still poorly understood, Netrin G1 might have a role as a regulator of anxiety, fear and spatial memory, behavioural traits impaired in the context of ...

Effects of Electrical Lesion of Basolateral Amygdala Nucleus on Rat Anxiety‐like Behavior under Acute, Sub‐chronic, and Chronic Stresses

07-Jan-2017 | Hoda Ranjbar, Maryam Radahmadi, Parham Reisi, Hojjatallah Alaei, Clinical and Experimental Pharmacology and Physiology, 2017

Abstract Stress contributes, as a risk factor, to such psychological disorders as anxiety. The effects of electrical lesions in the basolateral amygdala nucleus (BLA) were investigated on the locomotor activity and anxiety‐like behavior in different stress durations. For this purpose, rats ...

Effects of context preexposure and delay until anxiety retrieval on generalization of contextual anxiety [RESEARCH]

01-Jan-2017 | Marta Andreatta; Dorothea Neueder; Evelyn Glotzbach-Schoon; Andreas Mühlberger; Paul Pauli, Learning & Memory, 2017

Animal studies suggest that time delay between acquisition and retrieval of contextual anxiety increases generalization. Moreover, such generalization is prevented by preexposure to the context (CTX), presumably due to an improved representation of such context. We investigated whether ...

Primary auditory cortex regulates threat memory specificity [BRIEF COMMUNICATIONS]

01-Jan-2017 | Mattis B. Wigestrand; Hillary C. Schiff; Marianne Fyhn; Joseph E. LeDoux; Robert M. Sears, Learning & Memory, 2017

Distinguishing threatening from nonthreatening stimuli is essential for survival and stimulus generalization is a hallmark of anxiety disorders. While auditory threat learning produces long-lasting plasticity in primary auditory cortex (Au1), it is not clear whether such Au1 plasticity regulates ...

Onset and evolution of anxiety in Parkinson's disease

29-Dec-2016 | K. Zhu, J. J. van Hilten, J. Marinus, European Journal of Neurology, 2016

Background and purpose Anxiety is common in Parkinson's disease (PD) and has a great influence on quality of life. However, little is known about risk factors for development of anxiety in PD. We investigated which factors were associated with longitudinal changes in severity of anxiety ...

Reducing future fears by suppressing the brain mechanisms underlying episodic simulation [Psychological and Cognitive Sciences]

27-Dec-2016 | Roland G. Benoit; Daniel J. Davies; Michael C. Anderson, Proceedings of the National Academy of Sciences current issue, 2016

Imagining future events conveys adaptive benefits, yet recurrent simulations of feared situations may help to maintain anxiety. In two studies, we tested the hypothesis that people can attenuate future fears by suppressing anticipatory simulations of dreaded events. Participants repeatedly ...

N/OFQ system in brain areas of nerve‐injured mice: its role in different aspects of neuropathic pain

21-Dec-2016 | Palmisano M, Mercatelli D, Caputi FF, Carretta D, Romualdi P, Candeletti S., Genes, Brain and Behavior, 2016

ABSTRACT Several studies showed that chronic pain causes reorganization and functional alterations of supraspinal brain regions. The nociceptin‐NOP receptor system is one of the major systems involved in pain control and much evidence also suggested its implication in stress, anxiety and ...

Unveiling the Structure of Cognitive Vulnerability for Depression: Specificity and Overlap

16-Dec-2016 | Igor Marchetti; Tom Loeys; Lauren B. Alloy; Ernst H. W. Koster, PLoS ONE, 2016

by Igor Marchetti, Tom Loeys, Lauren B. Alloy, Ernst H. W. Koster There is extensive literature establishing the influence of rumination, hopelessness, and dysfunctional attitudes on depressive symptoms. However, it is unclear whether these vulnerability factors are distinctly related to ...
