Mutant Epidermal Growth Factor Receptor (EGFR) oncoproteins lacking most of subdomains I and II of the extracellular region, a deletion which includes most of the first of two cysteine-rich sequences, have been observed in multiple human epithelial tumors, including malignant gliomas. These EGFR oncoproteins, designated deltaEGFR or EGFRvIII, confer(More)
We have developed an extremely sensitive technique, termed immuno-detection amplified by T7 RNA polymerase (IDAT) that is capable of monitoring proteins, lipids, and metabolites and their modifications at the single-cell level. A double-stranded oligonucleotide containing the T7 promoter is conjugated to an antibody (Ab), and then T7 RNA polymerase is used(More)
The effects of Bacillus subtilis natto on performance and immune function of dairy calves during the preweaning phase were investigated in this study. Twelve Holstein male calves 7 ± 1 d of age were randomly allotted to 2 treatments of 6 calves. The Bacillus subtilis natto was mixed with milk and fed directly to the calves. The calves were weaned when their(More)
A retrospective analysis of the long-term outcome of patients with membranous lupus nephropathy (MLN) was conducted. One hundred Chinese patients, 90 females and 10 males with a mean age of 32+/-9 years, with systemic lupus erythematosus and biopsy-proven MLN (ISN/RPS2003 classification criteria) were enrolled in this study. The patient and renal survivals(More)
We retrospectively analyzed the clinicopathologic characteristics and prognosis of 33 patients with diffuse proliferative lupus nephritis (class IV LN) complicated with thrombotic microangiopathy (TMA). Eighty-one percent of patients had renal dysfunction (mean Scr 3.1 ± 2.0 mg/dl), among whom 42.4% needed acute hemodialysis. Nephrotic proteinuria, gross(More)
Overexpression of the HER2 receptor is observed in about 30% of breast and ovarian cancers and is often associated with an unfavorable prognosis. We have recently designed an anti-HER2 peptide (AHNP) based on the structure of the CDR-H3 loop of the anti-HER2 rhumAb 4D5 and showed that this peptide can mimic some functions of rhumAb 4D5. The peptide disabled(More)
The present study examined the effects of nicotine on the levels of dopamine and its metabolite 3,4-dihydroxy-phenylacetic acid (DOPAC) in the striatum and on spontaneous locomotor activity of C57 black mice that had been treated with the neurotoxin 1-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP). The levels of dopamine and DOPAC in the striatum were(More)
Monoclonal antibodies specific for the p185HER2/neu growth factor receptor represent a significant advance in receptor-based therapy for p185HER2/neu-expressing human cancers. We have used a structure-based approach to develop a small (1.5 kDa) exocyclic anti-HER2/neu peptide mimic (AHNP) functionally similar to an anti-p185HER2/neu monoclonal antibody, 4D5(More)
OBJECTIVE A retrospective evaluation of the clinical outcome and technical feasibility of kyphoplasty for the treatment of very severe osteoporotic vertebral compression fracture (vsOVCF). METHODS Patients with vsOVCF were treated with kyphoplasty and followed-up for 1 year. Vertebral body height variation, kyphotic angle, back pain (visual analogue(More)
Acute spinal cord lesions result in dramatic changes in neuronal function. Studies have shown that the peroxisome proliferator-activated receptor-γ agonist, rosiglitazone, has neuroprotective properties. The effect of rosiglitazone after acute spinal cord injury was examined in the present study. Rats were subjected to laminectomy only; laminectomy with(More)
