Increasing evidence demonstrates that there is marked damage and dysfunction in the white matter in Alzheimer’s disease (AD). The present study investigates the nature of white matter damage of patients with Alzheimer’s disease with diffusion tensor magnetic resonance imaging (DTI) and analyses the relationship between the white matter damage and the(More)
BACKGROUND Few studies have been conducted to investigate the impact of extreme cold events on mortality in subtropical regions. OBJECTIVE In the present study we aimed to investigate the effects of the 2008 cold spell on mortality and the possibility of mortality displacement in three subtropical cities in China. METHODS Daily mortality, air pollution,(More)
The distribution of nestin immunoreactivity was studied in the whole normal adult human forebrains using new anti-human nestin mouse monoclonal and rabbit polyclonal antiserum. The nestin immunoreactive cells could be divided into three types according to their morphological characteristics. The first type contained neuron-like nestin immunoreactive cells,(More)
Ginkgo biloba extract EGb761 has been shown to protect against beta-amyloid peptide (Abeta)-induced neurotoxicity but the specific mechanisms remain unclear. In the present study, effects of EGb761 and two of its constituents, quercetin and ginkgolide B, on the cytotoxic action of Abeta (1-42) were tested with human neuroblastoma SH-SY5Y cells. We found(More)
We investigated the functional recovery of motoneurons after reimplanting an avulsed ventral root in a rat model of traction injury. The eighth cervical root (C8) was avulsed by controlled traction and immediately reimplanted to the spinal cord. Spinal nerves from neighbouring segments (C5, C6, C7 and T1) were ligated and cut. After 12 or 20 weeks, the(More)
Active amyloid beta (Abeta) vaccination has been shown to be effective in clearing cerebral Abeta and improving cognitive function in mouse models of Alzheimer's disease (AD). The meningoencephalitis observed in AD vaccination trial was likely related to excessive T cell-mediated immunity caused by the immunogen Abeta(1-42). To avoid this toxicity, previous(More)
Standardized extract from the leaves of the Ginkgo biloba tree, labeled EGb761, is one of the most popular herbal supplements, taken for its multivalent properties. In this study, dosage effects of EGb761 on hydrogen peroxide (H(2)O(2))-induced apoptosis of human neuroblastoma SH-SY5Y cells were investigated. It was found that H(2)O(2)-induced apoptotic(More)
Based on the common characteristic of severe acute respiratory syndrome (SARS) and highly pathogenic avian influenza and the mechanism of inflammation and fibrosis, it is speculated that there should exist a fundamental pathological rule that severe acute lung injury (ALI)-induced rapid pulmonary fibrosis is caused by various etiological factors, such as(More)
Alzheimer's disease (AD) is characterized by amyloid β (Aβ) peptide aggregation and cholinergic neurodegeneration. Therefore, in this paper, we examined silibinin, a flavonoid extracted from Silybum marianum, to determine its potential as a dual inhibitor of acetylcholinesterase (AChE) and Aβ peptide aggregation for AD treatment. To achieve this, we used(More)
In the peripheral nervous system (PNS), root avulsion causes motoneuron degeneration, but the majority of motoneurons can survive axotomy. In order to study the mechanism of motoneuron degeneration, we compared the expression patterns of c-jun and neuronal nitric oxide synthase (nNOS), the well-known molecular players in PNS regeneration and degeneration,(More)
