BACKGROUND Prostate cancer has become a serious threat to the life of patients. microRNAs are small non-coding RNA molecules that regulate the growth and apoptosis of cells. We aimed to investigate the regulation and mechanism of microRNA (miR-143) in the proliferation and apoptosis of prostate cancer LNCap cells. MATERIAL AND METHODS miR-143 and control scramble miRNA were synthesized and respectively transfected into LNCap cells. The proliferation and apoptosis were detected by MTT assay, flow cytometry, and caspase-3 activity assay...

BACKGROUND: With improving surgical techniques for total elbow arthroplasty clinical outcomes have improved and its utilization continues to increase. Despite these advances, complication rates remain as high as 24%. Of these complications periprosthetic joint infection is one of the most common and morbid. The rheumatoid elbow remains a leading indication for total elbow arthroplasty. Patients with this condition frequently require immunosuppressive therapy, which places them at higher risk of both typical and atypical infections...

BACKGROUND: Fusarium verticillioides is a common maize pathogen causing ear rot (FER) and contamination of the grains with the fumonisin B1 (FB1) mycotoxin. Resistance to FER and FB1 contamination are quantitative traits, affected by environmental conditions, and completely resistant maize genotypes to the pathogen are so far unknown. In order to uncover genomic regions associated to reduced FER and FB1 contamination and identify molecular markers for assisted selection, an F2:3 population of 188 progenies was developed crossing CO441 (resistant) and CO354 (susceptible) genotypes...

BACKGROUND AND METHOD: Adolescents observe and imitate people to whom they are associated in their social context, and the normative factors sent out by reference groups are crucial determinants of their decision to smoke. The aim of the study is to investigate how adolescents' smoking changes when they are exposed to factors of pro-smoking normative influence by parents and peers, and how age moderate this relation. A cross sectional survey collected data from 5657 students, aged between 11 and 14, from public and private middle schools in the Italian region of Switzerland (Ticino) on their smoking habits, perceived parents' and peers' approval and smoking...

BACKGROUND: TMEM16A, a Ca-activated Cl channel, regulates various physiological functions such as mucin secretion. However, the role of TMEM16A in hypersecretion in asthma is not fully understood. OBJECTIVE: The aim of this study is to evaluate Cl ion transport via TMEM16A and determine the localization of TMEM16A in a guinea pig asthma model. METHODS: Guinea pigs were sensitized with OVA ip. on Day 1 and Day 8. On Day 22, we assessed OVA challenge-induced Cl ion transport in the sensitized tracheas ex vivo in an Ussing chamber, compared with the non-sensitized tracheas...

Preterm birth (PTB) is the single largest cause of death in infants and young children. The rate of PTB is significantly higher in male infants, particularly those that are born very preterm. Here we present evidence to suggest that the decidual renin-angiotensin system may play a role in inhibiting inflammation and maintaining the integrity of the fetal membranes during pregnancy, and that sex-specific alterations in the intrauterine RAS could contribute to the increased risk of PTB in male babies. Women carrying female fetuses have high levels of expression of decidual prorenin at term...

Objective To promote phenotype recovery of osteoarthritic articular chondrocytes (OACs) and induce chondrogenic differentiation of infrapatellar fat pad-derived stem cells (IPFPSCs) by indirectly coculturing these two types of cells. Methods The OACs and IPFPSCs were isolated and cultured in vitro. This experiment included single IPFPSCs group, single OACs group, and coculture group. After cells were cultured in vitro with chondrogenic medium for 21 days, the chondrocyte phenotypes were determined by HE staining (cell morphology), Alcian blue staining (glycosaminoglycan content) and immunofluorescence cytochemistry (collagen 1, collagen 2, collagen 3, aggrecan, SOX9)...

Objective To investigate the effect of rat bone marrow mesenchymal stem cells (BMSCs) on the proliferation and migration of rat RSC96 Schwann cells in vitro. Methods BMSCs of Sprague Dawley (SD) rats were isolated by bone marrow cell adherent method. The morphology of the third generation of BMSCs was observed by inverted microscopy. The cell surface antigen makers CD19, CD34, CD73, CD105 were detected by flow cytometry. The third-passage BMSCs differentiated into osteoblasts and adipocytes after exposed to bone-inducing and lipid-inducing media for 3 and 2 weeks, respectively, and then were identified by oil red O and alkaline phosphatase staining...

Objective To explore the possible mechanism of umbilical cord mesenchymal stem cells (UCMSCs) regulating milk protein synthesis in bovine mammary gland epithelial cells (BMECs). Methods UCMSCs and BMECs were co-cultured by double-chamber Transwell(TM), and other BMECs were cultured alone as a control group. Insulin like growth factor 1 receptor (IGF-1R) inhibitor AG1024 was used to treat cells. IGF-1, β casein (CSN2) and κ casein (CSN3) content in the supernatants were determined by ELISA; the relative expression abundance of Janus kinase and signal transducer and activator of transcription factor (JAK/STAT) signaling pathway-related genes were detected by quantitative real-time PCR (qRT-PCR); and after the cells were treated with JAK2 signal blocker AG490, qRT-PCR was performed to test the relative expression abundance of CSN2 and CSN3 mRNAs...

Polycyclic aromatic sulfur heterocycles (PASHs) and their alkyl derivatives can be released into aquatic systems via crude oil spills or via runoff from petroleum treated areas such as asphalt. Dibenzothiophene (DBT) and its derivatives, C1-DBT, C2-DBT, and C4-DBT were chosen as model compounds to investigate the relative impact of volatilization and hydroxyl radical degradation on estimates of their overall dissipation after entry into aquatic ecosystems as a function of depth using the Exposure Analysis Modeling System (EXAMS)...

Multi-modal anion exchange resins combine properties of both anion exchange and hydrophobic interaction chromatography for commercial protein polishing and may provide some viral clearance as well. From a regulatory viral clearance claim standpoint, it is unclear if multi-modal resins are truly orthogonal to either single-mode anion exchange or hydrophobic interaction columns. To answer this, a strategy of solute surface assays and High Throughput Screening of resin in concert with a scale-down model of large scale chromatography purification was employed to determine the predominant binding mechanisms of a panel of bacteriophage (i...

Histone deacetylases are recently identified to act as key regulators for cardiac pathophysiology and metabolic disorders. However, the function of histone deacetylase (HDAC) in controlling cardiac performance in type II diabetes and obesity remains unknown. Here we determine whether HDAC inhibition attenuates high fat diet (HFD)-induced cardiac dysfunction and improves metabolic features. Adult mice were fed with either HFD or standard chow food for 24 weeks. Starting at 12 weeks, mice were divided into four groups randomly, in which sodium butyrate (1%), a potent HDAC inhibitor, was provided to chow and HFD-fed mice in drinking water, respectively...

OBJECTIVE: To investigate performance of a biotinylated imaging probe 3a for targeted imaging of breast cancer cells. METHODS: Ultraviolet absorption spectrum and fluorescence spectrum were employed to analyze the spectral characteristics of 3a. The fluorescence spectrums of 3a treated with different concentrations of glutathione (GSH) were obtained to determine the sensibility of 3a to GSH. Flow cytometry was used to determine the cellular uptake of 3a by MCF-7 cells, MDA-MB-231 cells and Hs 578Bst cells in the presence or absence of biotin, and the imaging performance of 3a in the 3 cell lines was assessed under an inverted fluorescent microscope...
