Maize inflorescence provides a useful model to study the genetic and molecular control of meristems. Many classical maize mutants were described last century, providing important insights into the mechanism of developmental control. The fea*-9LB030 is a new maize spontaneous mutant controlled by a single recessive gene. The ears are fasciated in line at the(More)
Electrical stimulation of the auditory cortex (AC) causes both facilitatory and inhibitory effects on the medial geniculate body (MGB). The purpose of this study was to identify the corticofugal inhibitory pathway to the MGB. We assessed two potential circuits: 1) the cortico-colliculo-thalamic circuit and 2) cortico-reticulo-thalamic one. We compared(More)
This study aims to evaluate the protective effects of Yi-Qi-Fu-Mai sterile powder (YQFM) on myocardial oxidative damage and tries to identify the active components responsible for its pharmacological benefits. YQFM and the n-butanol extract of YQFM (YQFM-Bu) were administered to ISO-induced myocardial injury mice. Left ventricle weight index and(More)
An increasing number of recent studies indicate that multiple interacting factors can affect the invasion of plants. However, few studies have focused on asexual propagation and the interaction of propagation with environmental factors that regulate the invasive potential of introduced exotic species in aquatic habitats. This study was designed to(More)
BACKGROUND Stress is a conserved physiological response in mammals. Whereas moderate stress strengthens memory to improve reactions to previously experienced difficult situations, too much stress is harmful. METHODS We used specific β-adrenergic agonists, as well as β2-adrenergic receptor (β2AR) and arrestin knockout models, to study the effects of(More)
Patients with damage to the medial temporal lobe show deficits in forming new declarative memories but can still recall older memories, suggesting that the medial temporal lobe is necessary for encoding memories in the neocortex. Here, we found that cortical projection neurons in the perirhinal and entorhinal cortices were mostly immunopositive for(More)
Glutamate transporter-1 (GLT-1) plays a dual role in glutamate transportation: both normally devotion to the clearance of glutamate and during some pathological conditions extruding glutamate to the extracellular space. Therefore, it is uncertain whether increased expression of GLT-1 will actually be helpful against glutamate excitotoxicity. In this study,(More)
Terpene trilactones from Ginkgo biloba have been investigated extensively for their antioxidant and anti-ischaemic activities on the brain and the heart, but the mechanisms of these effects remain unclear. For the present study, a terpenoid constituent from G. biloba, bilobalide, was screened for protective effects on the ischaemic heart and the involvement(More)
CONTEXT Sheng-Mai-San (SMS) has been used for the treatment of cardiovascular disease for many years in China. OBJECTIVES This study investigated the protective effects and active ingredients of SMS on myocardial injury (MI) in mice. MATERIALS AND METHODS SMS and n-butanol extraction of SMS (SMS-Bu) were prepared and administered to ISO-treated mice(More)
BACKGROUND A number of studies have investigated the relationship between fibroblast growth factor receptor1 (FGFR1) gene copy number and survival in non-small cell lung cancer (NSCLC) patients. However, conclusions reported by different parties seem to be inconsistent, especially regarding the differences among different histopathologic subtypes. To derive(More)
