Using degenerate primers designed based on the conserved regions of the reported SLF/SFB genes, more than a dozen of different cDNA clones were isolated from pollen of three different apple S-genotypes by reverse transcription (RT)-PCR. The 5′- and 3′-rapid amplification of cDNA end in combination with RT-PCR allowed isolation of two full-length cDNAs,(More)
In some areas of cultivation, a lack of salt tolerance severely affects plant productivity. Apple, Malus x domestica Borkh., is sensitive to salt, and, as a perennial woody plant the mechanism of salt stress adaption will be different from that of annual herbal model plants, such as Arabidopsis. Malus zumi is a salt tolerant apple rootstock, which survives(More)
Mycoplasma pneumoniae is a frequent cause of community-acquired bacterial respiratory infections in children and adults. In the present study, using a proteomic approach, we studied the effects of M. pneumoniae infection on the protein expression profile of A549 human lung carcinoma cells. M. pneumoniae infection induced changes in the expression of(More)
The purposes of this study were to clarify the expression patterns of phosphorylated mammalian target of rapamycin (p-mTOR), mTOR, and phosphatase and tensin homolog (PTEN) in primary pancreatic neuroendocrine tumors (pNETs) and their significance in predicting clinical behaviors and postoperative outcomes. The expressions of p-mTOR, mTOR, and PTEN were(More)
BACKGROUND Gastric neuroendocrine carcinomas (g-NECs) are rare tumors that have aggressive biological behaviors and poor prognosis, but the prognostic factors of postoperative patients with g-NEC are still unclear. Our aim was to study and explore the clinical characteristics and prognostic factors of patients with g-NEC treated with radical surgery. (More)
OBJECTIVE The purpose was to describe the clinicopathological characteristics of pancreatic neuroendocrine tumors (pNETs) and evaluate prognosis-related factors in potentially resectable pNETs. METHODS The clinical data of 104 patients with pNETs who underwent surgery were retrospectively analyzed. RESULTS The mean (SD) age was 49.8 (14.6) years. The(More)
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a fatal disease characterized by fibroblastic foci and progressive scarring of the pulmonary parenchyma. IPF fibroblasts display increased proliferation and enhanced migration and invasion, analogous to cancer cells. This transformation-like phenotype of fibroblasts plays an important role in the development(More)
BACKGROUND AND AIMS Iron deficiency is one of the most common nutritional disorders in plants, especially in fruit trees grown in calcareous soil. Malus baccata is widely used as an apple rootstock in north China and is highly resistant to low temperatures. There are few studies on iron absorption by this species at the molecular level. It is very important(More)
The objectives of this study were to validate the immunohistochemical expression patterns of CK19 and KIT in primary pancreatic neuroendocrine tumors (pNETs) and to verify the potential biomarkers that can be used to predict the clinical behaviors and postoperative outcomes. The immunohistochemical expressions of CK19 and KIT were determined in normal(More)
Subglottic hemangiomas (SGH), which are rare benign tumors of the airway, are potentially life-threatening conditions that may require intervention. Propranolol appears to be an effective treatment for these tumors and should therefore be a first-line treatment for SGH that require intervention. This review presents the clinical presentation and diagnosis(More)
