BACKGROUND Neural Tube Defects (NTDs) are among the most prevalent and most severe congenital malformations worldwide. Polymorphisms in key genes involving the folate pathway have been reported to be associated with the risk of NTDs. However, the results from these published studies are conflicting. We surveyed the literature (1996-2011) and performed a(More)
Considerable evidence has emerged supporting the neuroprotective and cognition-preserving effects of estrogen, but these benefits are complicated by the evidence that estrogen increases the risk of certain cancers. Selective estrogen receptor modulators (SERMs) that specifically target the brain while avoiding peripheral organs offer a way to allow the(More)
Developmental dyslexia (DD) is a highly heritable neurological disorder that is prevalent in school-aged children. The dyslexia-associated gene DCDC2 is a member of the DCX family of genes known to play roles in neurogenesis, neuronal migration, and differentiation. However, the associations between DCDC2 genetic variations and dyslexia have yielded(More)
BACKGROUND There are many discussions about dyslexia based on studies conducted in western countries, and some risk factors to dyslexia, such as gender and home literacy environment, have been widely accepted based on these studies. However, to our knowledge, there are few studies focusing on the risk factors of dyslexia in China. Therefore, the aim of our(More)
Hirschsprung’s disease (HSCR) is a complex developmental defect characterized by the absence of enteric ganglia in the gastrointestinal tract. Although the genetic defect of enteric nervous system (ENS) was identified to play a critical role in the progress of HSCR, the systemic genetic dissection of HSCR still needs to be clarified. In this study, we(More)
Traumatic knee injuries frequently involve the disruption of multiple ligaments, such as a complete tear of the medial collateral ligament (MCL) together with a rupture of the anterior cruciate ligament (ACL) (Miyasaka, K., D. M. Daniel, M. L. Stone, and P. Hirshman. Am. J. Knee Surg. 4:3-8, 1991). Despite the high incidence, clinical management of this(More)
BACKGROUND Excess body weight measured as body mass index (BMI) has a positive association with risk of common cancers. However, previous meta-analyses related to BMI and liver cancer had inconsistent results. The purpose of the current study is to establish a nonlinear dose-response relationship between BMI and incidence risk of liver cancer. METHODS A(More)
BACKGROUND Lung cancer is the most commonly diagnosed cancer and leading cause of cancer mortality in the world. A single nucleotide polymorphism (SNP), rs402710, located in 5p15.33, was firstly identified to be associated with the lung cancer risk in a genome-wide association study. However, some following replication studies yielded inconsistent results.(More)
We investigated the role of nitric oxide (NO) in learning and memory formation in a radial maze test, by using the NO synthase (NOS) inhibitors, NG-nitro-L-arginine methyl ester (L-NAME) and 7-nitroindazole (7-NI), and an NO precursor, L-arginine. Rats were trained on a working and reference memory task in an eight arm radial maze for 30 days, wherein the(More)
This study examined the effects of sigma(1) receptor agonist SA4503 and neuroactive steroids dehydroepiandrosterone sulfate (DHEAS), pregnenolone sulfate (PREGS) and progesterone (PROG) on spatial working and reference memory in a radial arm maze task in rats. The insertion of a 6-min delay between the 2nd and 3rd choices caused a specific decline in(More)
