Aberrant gene expression is a hallmark of prostate cancer (PCa), the second deadliest disease affecting males worldwide. Dysregulation of miRNA has been associated with the progression of PCa, and in recent studies, miRNA 574-3p was found to be upregulated in cancerous prostate tissue. In this study, we characterize the effects of up-regulated miRNA 574-3p on gene expression in the tumor microenvironment through different bioinformatic tools such as Diana-Tools, KEGG Pathway database, and the Reactome Database...

Recurrent and refractory leiomyoma of uterus is one of the most common diseases in women of reproductive age. Despite its benign nature, uterine leiomyoma has presented an extremely deleterious impact on public health. The etiology of uterine leiomyoma remains unclear and clinical management remains suboptimal, leaving radical hysterectomy the only effective approach. Delineating the molecular mechanism underlying the leiomyoma initiation and progression remains an unmet clinical need. To screen proteins that were differentially expressed in uterine leiomyoma versus normal myometrium, we examined proteomic profile by isobaric tag for relative and absolute quantitation (iTRAQ) labeling coupled with liquid chromatography - tandem mass spectrometry (LC-MS/MS)...

This paper reports on the LGX fluorometric test for enzymatic MRSA/MSSA detection. It highlights the reasons rhodamines have been overlooked and also strategies to improve the synthesis of rhodamine-peptide conjugates. Evaluation of the LGX test for detection of MRSA/MSSA on surfaces is undertaken in the presence of potentially confounding E. coli and S. epidermidis for the first time.

Influenza and other acute respiratory infections are of great concern for public health, causing excessive morbidity and mortality throughout the world. Influenza virus A(H2N2), which caused a pandemic of so called "Asian flu" in 1957 was expelled from the human population by the new pandemic virus subtype H3N2 in 1968, however, influenza A(H2) viruses continue to circulate in wild birds and poultry. The lack of immunity in human population and the continued circulation of influenza A(H2) among animals makes emergence of a new pandemic virus possible...

Napier grass Stunt Disease (NSD) is a severe disease of Napier grass (Pennisetum purpureum) in Eastern Africa, caused by the leafhopper-transmitted bacterium Candidatus Phytoplasma oryzae. The pathogen severely impairs the growth of Napier grass, the major fodder for dairy cattle in Eastern Africa. NSD is associated with biomass losses of up to 70% of infected plants. Diagnosis of NSD is done by nested PCR targeting the phytoplasma DNA, which is difficult to perform in developing countries with little infrastructure...

INTRODUCTION: Treatment in the metastatic colorectal cancer has expanded with monoclonal antibodies targeting Epidermal Growth Factor Receptor, but is restricted to patients with a wild-type (WT) KRAS mutational status. The most sensitive assays for KRAS mutation detection in formalin-fixed paraffin embedded (FFPE) tissues are based on Real-time PCR. Among them, high resolution melting analysis (HRMA), is a simple, fast, highly sensitive, specific and cost-effective method, proposed as adjunct for KRAS mutation detection...

In human, microRNA-214 (miR-214) plays crucial roles in mechanisms of immunity. However, the potential importance of miR-214 in immune mechanisms in dairy cows has not been investigated. In this study, we assessed potential immunity-related functions of miR-214 in human 293A cells and in bovine mammary epithelial cells (BMECs). We found that NFATc3 and TRAF3 could be targeted by miR-214 in both 293A cells and BMECs. We also found that miR-214 indirectly inhibited the expression of MAP3K14, TBK1 and inflammatory cytokines IL-6 and IL-1β...

Duffy blood group system is of interest in several fields of science including transfusion medicine, immunology and malariology. Although some methods have been developed for Duffy polymorphism genotyping, not all of them have been sufficiently described and validated, and all present limitations. At the same time, the frequency of Duffy alleles and antigens in some densely populated regions of the world are still missing. In this study we present new tests for genotyping the major alleles of the Duffy blood system and describe Duffy alleles and antigens in blood donors and transfusion-dependent patients in Minas Gerais, Brazil...

Cytosolic pattern recognition receptors play key roles in innate immune response. Nucleotide binding and oligomerisation domain containing protein 1 (NOD1) belonging to the Nod-like receptor C (NLRC) sub-family of Nod-like receptors (NLRs) is important for detection and clearance of intra-cellular Gram negative bacteria. NOD1 is involved in activation of pro-inflammatory pathways. Limited structural data is available for NOD1. Using different templates for each domain of NOD1, we determined the full-length homology model of NOD1...

In this study, 17 male-specific amplified fragment length polymorphism (AFLP) markers were identified between male and female Humulus scandens plants. BLAST analysis revealed that 7 of the 17 sex-linked sequences were highly similar to retrotransposons. Two stable male-specific sequence-characterized amplified regions (SCAR) markers were developed. These AFLP and SCAR markers are novel molecular probes that can be used efficiently to identify the genetic gender of H. scandens and may provide a basis for further investigations on the evolution of sex chromosomes...

Some microRNAs have carcinogenic or tumor suppressive effects in breast cancer, which is the most common cancer in women worldwide. MiR-7 and miR-9 are tumor suppressor microRNAs, which induce apoptosis and inhibit proliferation in breast cancer cells. Moreover, miR-96 and miR-182 are onco-microRNAs that increase proliferation, migration, and tumorigenesis in breast cancer cells. This study aimed to identify the direct target genes of these four microRNAs in the human breast cancer cell lines MCF-7 and MDA-MB-231...

Salmonella is a major foodborne pathogen that is widespread in the environment and can cause serious human and animal disease. Since conventional culture methods to detect Salmonella are time-consuming and laborious, rapid and accurate techniques to detect this pathogen are critically important for food safety and diagnosing foodborne illness. In this study, we developed a rapid, simple and portable Salmonella detection strategy that combines thermophilic helicase-dependent amplification (tHDA) with a lateral flow assay to provide a detection result based on visual signals within 90 min...

The 2009 H1N1 pandemic (H1N1pdm09) was associated with a considerable influenza-related morbidity and mortality. Among the complications, Mycobacterial tuberculosis was recorded as a coinfection with influenza in rare cases. The full-length sequences of the viral haemagglutinin and neuraminidase of H1N1pdm09 influenza A virus were analyzed from a recently infected patient. The patient was chronically infected with Mycobacterium tuberculosis. Molecular modelling and in-silico docking of the virus, and other selected strains with the drug oseltamivir were conducted and compared...

The emergence of nanotechnology in biology helps to apply the gold nanoparticle probes for fast and accurate identification of pathogens compared to the time-consuming and non-precise phenotypic methods. In this study, two molecular methods have been established for the accurate identification of staphylococcus epidermidis from other coagulase-negative staphylococci. Multiplex PCR was performed using designed primers for Gmk2 and pta housekeeping genes, and SESB specific gene of S. epidermidis. Colorimetric detection by gold nanoparticle probes was carried out using two 20-base thiolated probes designed based on the sequence of pta housekeeping gene of S...

Human Bocaviruses (HBoV) were associated with respiratory diseases. Here, we assessed a TaqMan(®)-based PCR for the detection of all four HBoV subtype infections with a sensitivity up to 15 copies/reaction. To evaluate this assay on clinical samples, 178 nasopharyngeal aspirate specimens from pediatric cases were analyzed and HBoV genome was detected in 13 out of 178 patients with a viral load range between 1.6 × 10(3) and 9.4 × 10(7) copies/ml. These results indicated that this method could be used as an alternative technique for the diagnosis of HBoV infection...
