Recombinant antibodies with desirable characteristics that can replace polyclonal or monoclonal antibodies are important for enzyme-linked immunosorbent assay (ELISA) of residues of clenbuterol (CBL), an illicit veterinary drug. Here, we report our work on expression and purification of a mouse-derived anti-CBL single chain Fv (scFv) antibody in Escherichia(More)
Phage display method was used to clone anti-carbofuran (CBF) single chain Fv (scFv) gene. The heavy chain and light chain variable region genes were amplified by the polymerase chain reaction from the CBF-specific hybridoma cell lines 5D3 and assembled as a scFv DNA fragment with linker peptide (Gly(4)Ser)(3). The scFv DNA fragment was cloned into M13(More)
The production and characterization of an anti-clenbuterol single-chain Fv antibody (CBLscFv)-bacterial alkaline phosphatase (AP) fusion protein are described. The CBLscFv and the phoA gene of Escherichia coli strain K12 chromosomal DNA were cloned by PCR and sequentially inserted into the expression vector pBV220 to express the CBLscFv-AP fusion protein in(More)
Previous studies have demonstrated a close relationship between abnormal regulation of microRNA (miRNA) and various types of diseases, including epilepsy and other neurological disorders of memory. However, the role of miRNA in the memory impairment observed in epilepsy remains unknown. In this study, a model of temporal lobe epilepsy (TLE) was induced via(More)
Demyelinating diseases is common in neurology department, but its treatment is still not clear. A 40-year-old male who was addicted in heroin was hospitalized and presented worsening altered mental status in hospital. Brain magnetic resonance imaging (MRI) revealed a symmetrical diffuse long T1 and long T2 time abnormalities in the white matter of cerebral(More)
AIMS Amyloid β (Aβ) is considered to be an important mediator of the development and progression of Alzheimer's disease (AD). Its direct binding to p75(NTR), not TrkA, induces apoptosis, which is thought to be the most relevant feature of p75(NTR) regarding AD. In the present study we explored the regulation of p75(NTR) on Aβ production and accumulation(More)
OBJECTIVE To investigate the roles of Domain I and Domain II of hepatitis C virus (HCV) 5' untranslated region (UTR) in the translation initiation activity of HCV 5'UTR in different host cell lines. METHODS The eukaryotic expression plasmid pCMVNCRLuc (pCN1), in which full-length HCV 5'UTR regulates firefly luciferase expression, was modified by deleting(More)

Although environmental enrichment has been shown to improve functional and histologic outcomes in pre-clinical moderate-to-severe traumatic brain injury (TBI), there are a paucity of pre-clinical data regarding enrichment strategies in the setting of repetitive mild traumatic brain injury (rmTBI). Given the vast numbers of athletes and those in the military(More)
OBJECTIVE Our group has previously reported the role of P38 mitogen-activated protein kinase (MAPK) pathway in the memory impairment of pentylenetetrazole (PTZ)-kindled rats. However, any contribution of p38 MAPK pathways to the cognitive dysfunction of PTZ-kindled rats remains unclear. The objective of this study is to verify the relationship between p38(More)
