The activated newborn neurons participate in enriched environment induced improvement of locomotor function in APP/PS1 mice

After exposure to EE in APP/PS1 mice at the early stage of 2 months of age, the elevated plus maze and context fear condition were tested in those mice, followed by the observation of neurogenesis and activation extent in hippocampus. The results indicate that the activation of newborn neurons may participate in the improvement of behavioral performance in APP/PS1 mice after EE.

AKT1, PRDM4, and BAX are the natural markers of psychological endurance threshold

The significance of this study is to discover people with abnormal expression of AKT1, PRDM4, and BAX have lower PET and tend to commit abnormal behavior more easily. Understanding the PET will enable people to make self-adjustment or to intervene by professionals as soon as possible and in a timely manner in the face of various negative stimuli in work and life, especially for people with lower PET, people should intervene as early as possible to reduce the harm to the individual, family, and society.

Effect of intraoperative infusion of dexmedetomidine on postoperative recovery in patients undergoing endovascular interventional therapies: A prospective, randomized, controlled trial

In this manuscript, we firstly reported that the application of dexmedetomidine (starting at 0.5 μg/kg for 10 min followed by adjustment to 0.6 μg kg−1 hr−1 throughout the surgical procedure) could reduce both the consumption of total dose of nimodipine and sufentanil 48 hr after surgery and the prevalence of symptomatic cerebral vasospasm as well as increase the stability of hemodynamics. However, there were no significant differences among the three groups in terms of Glasgow coma scale and functional activity score during the first 48 hr after surgery, Glasgow Outcome Score at 3 months, or cerebral infarction after 30 days.

Prognostic factors for permanent neurological dysfunction after total aortic arch replacement with regional cerebral oxygen saturation monitoring

Factors such as ischemia, hypoxia, reperfusion injury, and internal environment disturbance caused by deep hypothermic circulatory arrest during surgery lead to severe damage to various organs. Intraoperative ΔrSO2min that is lower than the basal level of about 80%, advanced age, preoperative low platelet, and prolonged hemostasis are predictors of PND after aortic total arch replacement.

Altered amplitude of low-frequency fluctuation in basal ganglia correlates to pulmonary ventilation function in COPD patients: A resting-state fMRI study

  • In this study, we seek to determine the impaired domains of cognitive function in the COPD patients and explore the brain areas with aberrant ALFF value. The results suggest aberrant ALFF alteration in the deep brain may be directly related to lower PaO2 in COPD patients and associated with cognitive impairment of them.

Disruptions of the olfactory and default mode networks in Alzheimer's disease

  • First Published: 04 June 2019
Disruptions of the olfactory and default mode networks in Alzheimer's disease

Olfactory and memory scores can differentiate Alzheimer's disease (AD) from mild cognitive impairment (MCI). Neurodegeneration, as measured by hippocampus and primary olfactory cortex (POC) volume is similar in AD and MCI. Patterns of ON activation support compensatory mechanisms in MCI and not in AD. DMN suppression during olfactory processing is impaired in AD. Effective connectivity between DMN and ON, in a model of causal influence, is impaired in AD.

Conversion and reversion of anti-John Cunningham virus antibody serostatus: A prospective study

We performed a prospective study, including 110 multiple sclerosis patients, with repetitive testing of anti-John Cunningham virus (JCV) antibodies in predefined testing intervals. We were able to show that with testing of anti-JCV antibodies three times within short-term intervals seroconversion/-reversion due to assay variability can be indentified early, while real seroconversion due to a new infection with JCV is rare within an observational period of 1 year.

Epidemiology of neuromyelitis optica spectrum disorder in Denmark (1998–2008, 2007–2014)

Differences in accuracy of NMOSD diagnosis, completeness of case ascertainment and variability in assays for AQP4-IgG affect epidemiological studies of NMOSD. Data from two epidemiological studies in two decades from Denmark reflect the complexity. The increased recognition of NMOSD may facilitate prospective epidemiological studies with standardized methodologies that will enable specific conclusions.

Plasma Brain-Derived Neurotrophic Factor (BDNF) and serum cortisol levels in a sample of workers exposed to occupational stress and suffering from Adjustment Disorders

In this study a group of workers exposed to occupational stress and suffering from Adjustment Disorders (AD) exhibited plasma BDNF levels significantly higher than those of healthy controls. In patients but not in controls plasma BDNF levels showed a significant positive correlation with serum cortisol levels. BDNF could play a key role in the pathophysiology of stress-related disorders and its peripheral levels elevation could contribute to protect neurons under stress. Further research is needed focusing on biomarkers for stress-related disorders as a potential tool for the diagnosis and prevention of occupational diseases.

Sentence processing is modulated by the current linguistic environment and a priori information: An fMRI study

  • In this study we show distinct contextual influences on language processing in the brain. We show that brain areas related to cognitive control use information on the statistics of syntactic structures to modulate processing in the language network. Conversely, a priori verb preferences modulate the activation in the language network directly.

Cistanche extracts ameliorates the neurotoxicity induced by hydrogen peroxide in new mutant DJ-1-transfected neuroblastoma cellular models

In this study, we established hydrogen peroxide (H2O2) induced Leucine166Proline (L166P) and C106S DJ-1-transfected neuroblastoma (SH-SY5Y) cellular models of Parkinson's disease (PD) and investigated the effects of Cistanche extracts, including acteoside, echinacoside, caffeic acid, and Cistanche total glycosides on these two models. We successfully established sensitive and stable H2O2 induced L166P DJ-1- and C106S DJ-1-transfected SH-SY5Y cell models of PD and Cistanche extracts may thus be useful for treating PD.
