BACKGROUND: Dendritic messenger RNA (mRNA) localization and subsequent local translation in dendrites critically contributes to synaptic plasticity and learning and memory. Little is known, however, about the contribution of RNA-binding proteins (RBPs) to these processes in vivo. RESULTS: To delineate the role of the double-stranded RBP Staufen2 (Stau2), we generate a transgenic rat model, in which Stau2 expression is conditionally silenced by Cre-inducible expression of a microRNA (miRNA) targeting Stau2 mRNA in adult forebrain neurons...

BACKGROUND: Frailty is a common problem among older people and it is associated with an increased risk of death and long-term institutional care. Early identification of frailty is necessary to prevent a further decline in the health status of home care clients. The aims of the present study were to determine the prevalence of frailty and associated factors among 75-year-old or older home care clients. METHODS: The study participants were 75-year-old or older home care clients living in three cities in Eastern and Central Finland...

BACKGROUND: The prevalence of long-term conditions (LTCs) and multiple-morbidity is increasing. Depression prevalence increases with the number of LTCs. Self-management of LTCs improves outcomes, but depression impacts on self-management. Unscheduled hospital care may be a proxy for failure of planned care to support successful self-management. METHODS: Retrospective observational study based on routine NHS datasets covering 19 LTCs. Prevalence of LTCs and depression was identified in all primary care registered adults in one English city (n = 469,368)...

BACKGROUND: Although observer-rated instruments assessing therapist's adherence to relapse-preventive treatments are available, they do not adequately cover specific relapse-preventive elements that focus on implementation of strategies after terminating treatment. This study describes the development of the KERI-D (Kodierbogen zur Erfassung Rückfallprophylaktischer Interventionen bei Depression/Coding System to Assess Interventions of Relapse Prevention in Depression). The KERI-D is a new observer-based rating tool for acute or continuation/maintenance-phase sessions and assesses relapse-prevention elements including implementation into patient's daily routines...

INTRODUCTION: Physical activity (PA) can modify cardiovascular and other health risks in people with stroke, but we know little about long-term PA in this group. This study aims to describe PA levels and investigate relationships between PA, cardiovascular risk factors, mobility and participant characteristics (eg, age, mood and fatigue) in the 2 years following rehabilitation discharge after first stroke. METHODS AND ANALYSIS: This is a longitudinal observational study with follow-up at 6, 12 and 24 months after rehabilitation discharge...

BACKGROUND: Seasonal affective disorder (SAD) is mainly characterized by a seasonal pattern of depressive recurrences over the years. However, few studies have been conducted on the long-term course of patients with SAD, whose findings raised questions about the diagnosis stability over time. This study aimed to better characterize the diagnosis evolution, and determine prognosis markers. METHODS: An initial cohort of 225 outpatients diagnosed as having a SAD, was assessed at baseline (T1) for clinical symptoms and response to bright light therapy...

BACKGROUND: Chronic postsurgical pain (CPSP) is a reported risk for women undergoing breast reconstruction, but it remains unclear that such persistent pain is induced by reconstructive surgery. To address this concern, this prospective cohort study examined the prevalence of and risk factors associated with CPSP among women undergoing breast reconstruction. MATERIALS AND METHODS: Women (n = 1996) recruited for the Mastectomy Reconstruction Outcomes Consortium (MROC) Study were assessed preoperatively and at two-years postoperatively for relevant medical/...

Overconsumption of high-fat diets is one of the strongest contributing factors to the rise of obesity rates. Orexin neurons are known to be activated by palatable high-fat diet and mediate the activation of the mesolimbic reward pathway, resulting in further food intake. While short-term exposure to high-fat diet is known to induce synaptic plasticity within the mesolimbic pathway, it is unknown if such changes occur in orexin neurons. To investigate this, 3-week old male rats were fed a palatable high-fat western diet (WD) or control chow for 1 week and then in vitro patch clamp recording was performed...

Resveratrol is a natural phytoalexin synthesized by plants, including grapes. It displays a wide range of neuroprotective benefits associated with anti-aging. Recent studies have shown that resveratrol regulates dopaminergic transmission and behavioral effects of drugs of abuse. The goal of the present study is to investigate whether and how resveratrol alters basal inhibitory synaptic transmission and cocaine-induced inhibitory synaptic plasticity in dopamine neurons of the ventral tegmental area (VTA). We report that resveratrol elevated cAMP levels by itself and further potentiated a forskolin-induced increase in cAMP levels in midbrain slices, consistent with reported effects of inhibition of phosphodiesterases (PDEs)...

Hebbian plasticity is thought to require glutamate signalling. We show this is not the case for hippocampal presynaptic long-term potentiation (LTPpre), which is expressed as an increase in transmitter release probability (Pr). We find that LTPpre can be induced by pairing pre- and postsynaptic spiking in the absence of glutamate signalling. LTPpre induction involves a non-canonical mechanism of retrograde nitric oxide signalling, which is triggered by Ca(2+) influx from L-type voltage-gated Ca(2+) channels, not postsynaptic NMDA receptors (NMDARs), and does not require glutamate release...

AIM: To determine the survival time and predictors of survival of residents in a nursing home. METHODS: Nursing home residents admitted from June 2008 (when the nursing home started operating) to December 2012 (n = 230) to a new nursing home in Hong Kong were prospectively followed. The predictors of survival in the residents were assessed annually, with the exception of those who did not want to continue with the study, or were hospitalized, discharged from the nursing home or died, to compare changes occurring from 2008 to 2012...

Long-term potentiation (LTP) is the persistent increase in the strength of the synapses. However, the neural networks would become saturated if there is only synaptic strenghthening. Synaptic weakening could be facilitated by active processes like long-term depression (LTD). Molecular mechanisms that facilitate the weakening of synapses and thereby stabilize the synapses are also important in learning and memory. Here we show that blockade of dopaminergic D4 receptors (D4R) promoted the formation of late-LTP and transformed early-LTP into late-LTP...

The concept of the bipolar-spectrum and of mixed features being a bridge between major depressive disorders and bipolar disorders (BDs) has become increasingly important in mood-disorder diagnoses. Under these circumstances, antidepressants (ADs) and mood stabilizers (MSs) should be used with caution in the treatment of major depressive episodes (MDEs) and to obtain long-term stability in BDs. Before treating MDEs, screening tools, specific symptom evaluation and medical history should be used to distinguish between bipolarity and mixed features in patients for whom AD monotherapy may present a risk...

Laszlo Vutskits
Major depressive disorder is a frequent and devastating psychological condition with tremendous public health impact. The underlying pathophysiological mechanisms involve abnormal neurotransmission and a relatedly impaired synaptic plasticity. Since general anesthetics are potent modulators of neuronal activity and, thereby, can exert long-term context-dependent impact on neural networks, an intriguing hypothesis is that these drugs could enhance impaired neural plasticity associated with certain psychiatric diseases...

The prelimbic cortex (PL) and infralimbic cortex (IL) play a role in context-induced reinstatement of heroin seeking in an animal model of drug relapse. Both the PL and IL receive direct glutamatergic projections from the ventral CA1 (vCA1), which is also involved in context-induced reinstatement of cocaine and heroin seeking. Here we studied the role of vCA1-PL and vCA1-IL projections in context-induced reinstatement of heroin seeking by using electrophysiological, neuropharmacological, chemogenetic and molecular methods...

Protein kinase C (PKC), a family of serine/threonine protein kinases, mediates a myriad of patho-physiological cellular events in various tissues. The originally discovered PKC (conventional) requires the binding of diacylglycerol and Ca(2+) for full activation. The conventional PKC consists of four isoforms, PKCα, PKCβI/βII, and PKCγ. PKCα and PKCβI/βII are expressed in the cells of various tissues including the brain, while PKCγ is present specifically in neurons of the brain and spinal cord. The cerebellum expresses the largest amount of PKC with all its four isoforms...
