Activity in the rodent prelimbic (PL) cortex contributes to consolidation, retrieval and reconsolidation of learned fear. The PL cortex is considered homologous to the primate dorsal anterior cingulate cortex (dACC). In patients with post-traumatic stress disorder (PTSD), the dACC is often reported to be hyperactive after acquisition and/or around the retrieval of the traumatic memory. It is still unknown, however, whether there is a relationship between altered dACC functioning at these time points and PTSD-associated behavioral outcomes, such as fear overgeneralization...

MicroRNA-27a (miR-27a) has been reported to be a brain-specific miRNA and aberrantly expressed in the brain suffered from traumatic brain injury (TBI). The present study is designed to investigate the potential role and molecular mechanism of miR-27a in the pathogenesis of TBI. The level of miR-27a in brain was manipulated by intracerebroventricular injection of lentiviral-encoding miR-27a before TBI induction. Real-time PCR was used to detected miR-27a and Forkhead box O3a (FoxO3a) levels in the hippocampus...

PURPOSE: The aim of the study was to compare neuromuscular fatigue induced by repeated sprint running vs cycling. METHODS: Eleven active male participants performed two repeated maximal sprint protocol (5×6 s, 24-s rest periods, 4 sets, 3-min between sets), one in running (treadmill) and one in cycling (cycle ergometer). Neuromuscular function, evaluated before (PRE), 30 s after the first (S1), the second (S2), and the last set (LAST), and 5 min after the last set (POST5), consisted in determining knee extensors maximal voluntary torque (MVC), voluntary activation (VA), single twitch (Tw), high- (Db100) and low- (Db10) frequency torque, and maximal muscle compound action potential (M-wave) amplitude and duration of vastus lateralis...

The higher prevalence of multiple sclerosis (MS) in females, along with the modulation of disease activity observed during pregnancy and the post-partum period, has suggested a hormonal influence in MS. Even if prolactin (PRL) does not belong to the sex hormones family, its crucial role in female reproduction and lactation has prompted great efforts to understand if PRL could represent a gender factor in the pathogenesis of MS and experimental autoimmune encephalomyelitis (EAE), the animal model for this disease...

OBJECTIVE: Anxiety and depression are highly prevalent disorders in adolescence. They are associated with deficits in working memory (WM), which also appears to increase rumination, worry, and negative mood. WM training, especially in an emotional context, might help in reducing or preventing these disorders. The current study investigated the direct effects of online emotional WM training on WM capacity, and short- and long-term effects on symptoms of anxiety and depression, and secondary measures of emotional functioning...

This work is devoted to critical analysis and reexamination of the problem of lateral heterogeneity of the trans-thylakoid pH difference (ΔpH=pHout-pHin) in thylakoid membranes of chloroplasts. Correct measurements of ΔpH may be complicated by nonuniform partitioning of the protons pumped into the lumen of granal (stacked) and stroma-exposed thylakoids. We have compared results of ΔpH estimations in isolated bean chloroplasts by two different methods. One of the methods is based on the use of pH-sensitive spin-probes...

Stem cells are important for regenerative medicine mainly due to their multilineage differentiation capacity. However, the cells rapidly loose this capability during culturing. Cryopreservation preserves the differentiation potential of the cells, until they are needed. In this study, specific cell properties of multipotent stromal cells (MSCs), from the common marmoset monkey Callithrix jacchus MSCs derived from amnion (Am) and bone marrow (Bm) were studied in order to predict optimal cooling rates for cryopreservation...

INTRODUCTION: Mild traumatic brain injury (mTBI) outcomes are variable, and 10-15% may suffer from prolonged symptoms beyond 3 months that impair the child's return to normal activities. Neurophysiological mechanisms of mTBI are incompletely understood, particularly in children, but alterations in cortical excitability have been proposed to underlie post-concussion syndrome. Improved understanding is required to advance interventions and improve outcomes. OBJECTIVE/HYPOTHESIS: To determine if cortical excitability is altered in children with mTBI, and its association with clinical symptoms...

Taking a big breath is known to reverse bronchoconstriction induced by bronchochallenge in healthy subjects; this bronchodilatory effect of deep inspiration (DI) is diminished in asthmatics. The mechanism underlying the DI effect is not clear. Observations from experiments using isolated airway smooth muscle (ASM) preparations and airway segments suggest that straining of ASM due to DI could lead to bronchodilation, possibly due to strain-induced reduction in ASM contractility. However, factors external to the lung cannot be excluded as potential causes for the DI effect...

BACKGROUND: Postoperative delayed paradoxical depression (PDPD) is a psychiatric condition described in patients who undergo a major surgery without complications, do not have a history of mood disorders, but nevertheless become clinically depressed. PDPD has been recognized in major surgical interventions such as coronary artery bypass surgery. We sought to determine the incidence and potential factors associated with PDPD after surgical treatment of intracranial aneurysms. METHODS: The cohort of 105 patients was derived from a prospective observational dataset of 3788 consecutive cases of intracranial aneurysms accrued from 1991-2015...

CQ is an anti-malaria drug, which has been used for years. However, there are published articles about its activity in anti-cancers. The aim of this approach was to look at possibility and related mechanisms of anti-breast cancer (mouse breast cancer cell line 4T1) by CQ alone. The studies of anti 4T1 in vitro and in vivo by CQ were performed. The growth of 4T1 in vitro and in vivo, survival of mice post treatment with CQ, changes of immune parameters and microenvironment in mice were evaluated. Our results demonstrate that CQ could markedly inhibit growth of 4T1 in vitro through inducing apoptosis of cells, inhibiting secretion of TGF-β and prolong the mice survival in vivo through boosting immune system by upregulating CD8+ T cell, and through down-regulating tumor associated macrophages (TAM), myeloid derived suppressing cells (MDSC) and Tregs, in microenvironment of mice bearing tumor...

Observational and interventional studies indicate a direct link between the patients' physical activity and the extent of behavioral and psychological symptoms of dementia (BPSD). At present, there are no evidence-based recommendations for physical exercise in the acute dementia care settings. Hence, this systematic review investigates the effects of short-term exercise trials on BPSD. Trials with a length up to three months investigating the effects of structured exercise interventions on BPSD in acute dementia care settings were included...

Human particulate dentin (HPD) shows potential as an alternative bone grafting material. However, the mechanism of bone healing at the molecular level after grafting with HPD is unclear. This study assessed the histological and global gene expression of bone tissues grafted with HPD. The HPD was prepared to 250-500 µm in size. X-ray diffraction (XRD) and energy dispersive x-ray spectroscopy (EDX) were performed to confirm the crystal structure, organic compound residues, and surface morphology, respectively...

Equid herpes virus type-1 (EHV-1) is a major pathogen of horses, causing abortion storms and outbreaks of herpes virus myeloencephalopathy. These clinical syndromes are partly attributed to ischemic injury from thrombosis in placental and spinal vessels. The mechanism of thrombosis in affected horses is unknown. We have previously shown that EHV-1 activates platelets through virus-associated tissue factor-initiated thrombin generation. Activated platelets participate in thrombus formation by providing a surface to localize coagulation factor complexes that amplify and propagate thrombin generation...

Chronic kidney disease (CKD), is characterized by a progressive loss of renal function and increase in cardiovascular risk. In this review paper, we discuss the pathophysiology of increased sympathetic nerve activity in CKD patients and raise the possibility of endurance exercise being an effective countermeasure to address this problem. We specifically focus on the potential role of endurance training in altering renal sympathetic nerve activity as increased renal sympathetic nerve activity negatively impacts kidney function as well indirectly effects multiple other systems and organs...
