BACKGROUND: Cognitive behavioural therapy (CBT), including exposure and ritual prevention, is a first-line treatment for obsessive-compulsive disorder (OCD), but few reliable predictors of CBT outcome have been identified. Based on research in animal models, we hypothesized that individual differences in basolateral amygdala-ventromedial prefrontal cortex (BLA-vmPFC) communication would predict CBT outcome in patients with OCD. METHODS: We investigated whether BLA-vmPFC resting-state functional connectivity (rs-fc) predicts CBT outcome in patients with OCD...

The basolateral amygdala receives a very dense cholinergic innervation from the basal forebrain that is important for memory consolidation. Although behavioral studies have shown that both M1 and M2 muscarinic receptors are critical for these mnemonic functions, there have been very few neuroanatomical and electrophysiological investigations of the localization and function of different types of muscarinic receptors in the amygdala. In the present study we investigated the subcellular localization of M2 muscarinic receptors (M2Rs) in the anterior basolateral nucleus (BLa) of the mouse, including the localization of M2Rs in parvalbumin (PV) immunoreactive interneurons, using double-labeling immunoelectron microscopy...

Dysferlinopathy is an autosomal recessive muscular dystrophy characterized by the progressive loss of motility that is caused by mutations throughout the DYSF gene. There are currently no approved therapies that ameliorate or reverse dysferlinopathy. Gene delivery using adeno-associated vectors (AAVs) is a leading therapeutic strategy for genetic diseases; however, the large size of dysferlin cDNA (6.2 kB) precludes packaging into a single AAV capsid. Therefore, using 3D structural modeling and hypothesizing dysferlin C2 domain redundancy, a 30% smaller, dysferlin-like molecule amenable to single AAV vector packaging was engineered (termed Nano-Dysferlin)...

BACKGROUND: IMP-producing Klebsiella pneumoniae (IMPKpn) exhibits sporadic prevalence in China. The mechanisms related to the spread of IMPKpn remain unclear. METHODS: Carbapenem non-susceptible K. pneumoniae isolates were collected from our hospital. The genetic relatedness, antimicrobial susceptibility, as well as sequence types (ST) were analyzed by pulsed-field gel electrophoresis (PFGE), VITEK 2 AST test Kit, and multilocus sequence typing (MLST), respectively...

The dopamine (DA) D3 receptor (D3R) is highly expressed in the basolateral nucleus of the amygdala (BLA), a neural region critical for processing opiate-related reward and withdrawal aversion-related memories. Functionally, D3R transmission is linked to downstream Cdk5 and calcineurin signaling, both of which regulate D3R activity states and play critical roles in memory-related synaptic plasticity. Previous evidence links D3R transmission to opiate-related memory processing, however little is known regarding how chronic opiate exposure may alter D3R-dependent memory mechanisms...

Postpartum estrogen (E2) withdrawal is known to be a particularly vulnerable time for depressive symptoms. In this study, ovariectomized (OVX) mice were treated with co-administration of estradiol benzoate and progesterone (E2/P4) followed by administration of E2 alone (E2) and a subsequent E2 withdrawal (EW) to mimic the hormonal changes during pregnancy and postpartum. The objective of this study was to investigate the influence of E2 withdrawal after hormone-simulated pregnancy on synaptic function and plasticity in basolateral amygdala complex (BLA)...

BACKGROUND: Risk for alcohol use disorders (AUDs) in adulthood is linked to alcohol drinking during adolescence, but understanding of the neural and behavioral consequences of alcohol exposure during adolescence remains incomplete. Here, we examined the neurobehavioral impact of adolescent chronic intermittent EtOH (CIE) vapor exposure in mice. METHODS: C57BL/6J-background Thy1-EGFP mice were CIE-exposed during adolescence or adulthood and examined, as adults, for alterations in the density and morphology of dendritic spines in infralimbic (IL) cortex, prelimbic (PL) cortex, and basolateral amygdala (BLA)...

Objectives: Detection of rarer carbapenemases is challenging, as it requires molecular assays with comprehensive coverage or the use of phenotypic methods for the detection of carbapenemase activity. We describe a new class A carbapenemase, FRI-2, in an Enterobacter cloacae complex isolate following implementation of an in-house multiplex PCR for the detection of 'rare' class A carbapenemases. Methods: MICs were determined by agar dilution. A carbapenem-resistant E...

Carbapenem-resistant Acinetobacter baumannii (CRAB) is endemic in Greece. CRAB initially emerged in 2000 and since then, carbapenemases still have a crucial role in CRAB appearance, except for a few cases resulting from efflux pump or outer-membrane protein mechanisms. OXA-type carbapenemases present the highest prevalence worldwide and bla OXA-23-like and bla OXA-58-like are the most important genes found; VIM-yielding CRAB have also been detected, while a single CRAB isolate producing NDM has quite recently emerged in Greece...

A history of intermittent, limited sucrose intake (LSI) attenuates the hypothalamic-pituitary-adrenocortical (HPA) axis stress response, and neuronal activity in the basolateral amygdala (BLA) is necessary for this HPA-dampening. LSI increases the expression of plasticity-associated genes in the BLA; however, the nature of this plasticity is unknown. As BLA principal neuron activity normally promotes HPA responses, the present study tests the hypothesis that LSI decreases stress-excitatory BLA output by decreasing glutamatergic and/or increasing GABAergic inputs to BLA principal neurons...

Early-life exposure to calorie-dense food, rich in fat and sugar, contributes to the increasing prevalence of obesity and its associated adverse cognitive and emotional outcomes at adulthood. It is thus critical to determine the impact of such nutritional environment on neurobehavioral development. In animals, maternal high-fat diet (HFD) consumption impairs hippocampal function in adult offspring, but its impact on hippocampal neuronal morphology is unknown. Moreover, the consequences of perinatal HFD exposure on the amygdala, another important structure for emotional and cognitive processes, remain to be established...

The amygdala plays a central role in fear conditioning and extinction. The medial intercalated (mITC) neurons are GABAergic cell clusters interspaced between the basolateral (BLA) and central amygdala (CeA). These neurons are thought to play a key role in fear and extinction, controlling the output of the CeA by feed-forward inhibition. BLA to mITC cell inputs are though to undergo synaptic plasticity, a mechanism underlying learning, which is mediated by NMDA-receptor dependent mechanisms that require changes in cytosolic calcium...

The amygdala mediates many forms of emotional learning, during which the central nucleus of amygdala (CeA) functions as a major output of the amygdala by converging inputs from the basolateral nucleus (BLA) and other amygdalar subregions. However, the contribution of BLA-CeA synaptic transmission and plasticity of this transmission after exposure to emotional stimuli remains to be completely understood. Using paired recording, we simultaneously recorded BLA and CeA neurons, and observed that BLA-CeA transmission was glutamatergic...

BACKGROUND: Neonatal exposure to anesthetics induces neuronal apoptosis and long-term cognitive dysfunction in rodents. We showed that the nicotinamide adenine dinucleotide phosphate-oxidase inhibitor apocynin not only reduces neurotoxicity by decreasing superoxide levels and preventing mitochondrial dysfunction but also improves long-term memory impairment in neonatal mice exposed to sevoflurane. We also found that after the contextual fear conditioning test, glutamatergic neurons expressed c-Fos (neural activation) regardless of previous exposure to sevoflurane...

We hypothesized short-term endurance exercise (EN) in hypoxia (HY) to exert decreased mitochondrial adaptation, peak oxygen consumption (VO2peak) and peak power output (PPO) compared to EN in normoxia (NOR) and hyperoxia (PER). 11 male subjects performed repeated unipedal cycling EN in HY, PER, and NOR over 4 weeks in a cross-over design. VO2peak, PPO, rate of perceived exertion (RPE) and blood lactate (Bla) were determined pre- and post-intervention to assess physiological demands and adaptation. Skeletal muscle biopsies were collected to determine molecular mitochondrial signaling and adaptation...
