this study was conducted to detect the presence ofseja gene among salmonella enteritidis isolates from poultry sources by polymerase chain reaction (pf'r) and evaluate its potential as diagnostic and epidemiological tools. thirty salmonella isolates from poultry sources: broilers. broiler breeders, layers, hatcheries, and poultry abattoirs were investigated. upper and forward primers were const...
MicroRNAs act as key regulators in carcinogenesis and progression in various cancers. In present study, we explored the role of miR-340 in the breast cancer progression. Our results showed that overexpression of miR-340 inhibits breast cancer cell proliferation and invasion, whereas depletion of miR-340 promotes breast cancer progression. Molecularly, ZEB1 was identified as a target gene of miR...
BACKGROUND Gastric cancer is among the most common types of cancer, with high morbidity and mortality. MicroRNAs (miRNAs) play vital roles in the tumorigenesis and biology of gastric cancer. This study aimed to reveal the role of miR-340 in gastric cancer cell proliferation and apoptosis and to elucidate the potential mechanisms. MATERIAL AND METHODS Human gastric cancer cells SGC-7901 were use...
OBJECTIVE To analyze clinical characteristics and prognostic factors of patients with malignancies combined with acute kidney injury (AKI), providing a basis for clinical AKI prevention and prognosis improvement. METHOD Hospitalized patients in the Central Hospital of Nephrology from January 2008 to December 2013 were screened by electronic medical record system; Statistical analysis formalig...
The influence of UV irradiation on pigmentation is well established, but the molecular and cellular mechanisms controlling dendrite formation remain incompletely understood. MicroRNAs (miRNAs) are a class of small RNAs that participate in various cellular processes by suppressing the expression of target mRNAs. In this study, we investigated the expression of miRNAs in response to UVB irradiati...
Large scale and operational applications based on contiguous coverage with SAR data require a set of dedicated techniques in terms of signal handling and product interpretation. The GRFM SAR map of the West African rainforest domain is derived from some 340 JERS-1 SAR images acquired in a time span of 45 days. The original data with a pixel spacing of 12.5 m are spatially compressed by wavelet ...
Materials and methods To analyze the catalytic activity of PHGDH on possible alternative substrates, we conducted in vitro biochemical assays on recombinant human PHGDH. The reaction rate in the reductive direction with various substrates was monitored based on NADH consumption, measured by absorbance at 340 nm. The identity and chirality of products were analyzed by liquid chromatography-mass ...
The 600 kDa neutrophil membrane neutral protease, which had been shown to generate bioactive peptides from the acute-phase reactant C-reactive protein, has now been shown to have fibrinogenolytic activity that is distinct from fibrinogenolysis by plasmin and neutrophil lysosomal enzymes. This protease gradually reduces the apparent molecular mass of fibrinogen (340 kDa) to non-clottable product...
Glioblastoma is the most common primary brain tumor in adults; with a survival rate of 12 months from diagnosis. However, a small subgroup of patients, termed long-term survivors (LTS), has a survival rate longer then 12-14 months. There is thus increasing interest in the identification of molecular signatures predicting glioblastoma prognosis and in how to improve the therapeutic approach. Her...
