Large-scale, case-control genome-wide association studies (GWASs) have revealed genetic variations associated with diverse neurological and psychiatric disorders. Recent advances in neuroimaging and genomic databases of large healthy and diseased cohorts have empowered studies to characterize effects of the discovered genetic factors on brain structure and function, implicating neural pathways and genetic mechanisms in the underlying biology. However, the unprecedented scale and complexity of the imaging and genomic data requires new advanced biomedical data science tools to manage, process and analyze the data. In this work, we introduce Neuroimaging PheWAS (phenome-wide association study) a web-based system for searching over a wide variety of brain-wide imaging phenotypes to discover true system-level gene-brain relationships using a unified genotype-to-phenotype strategy. This design features a user-friendly graphical user interface (GUI) for anonymous data uploading, study definition and management, and interactive result visualizations as well as a cloud-based computational infrastructure and multiple state-of-art methods for statistical association analysis and multiple comparison correction. We demonstrated the potential of Neuroimaging PheWAS with a case study analyzing the influences of the apolipoprotein E (APOE) gene on various brain morphological properties across the brain in the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort. Benchmark tests were performed to evaluate the system's performance using data from UK Biobank. The Neuroimaging PheWAS system is freely available. It simplifies the execution of PheWAS on neuroimaging data and provides an opportunity for imaging genetics studies to elucidate routes at play for specific genetic variants on diseases in the context of detailed imaging phenotypic data.Human milk is the best nutrient for infants. The donor human milk is stored in a milk bank before pasteurization. However, the human milk is not sterile and could be colonized with different types of bacteria. Many studies have shown S. aureus to be the most prevalent potential pathogen detected in human milk. This study characterized 22 methicillin-resistant and methicillin-sensitive Staphylococcus aureus isolates from raw human milk for the presence of virulence genes and agr type. Moreover, the genotypic as identified characterization was realized. selleck chemical The presence of virulence genes sei, seg, sec, seh, and etb was identified in resistant and sensitive strains. We observed the predominance of agr type II. The presence of SCCmec IV (67%, 4/6) and V (33%, 2/6) characterized resistant strains as CA-MRSA. Endemic lineages detected (ST1635/CC5-t002, ST5/CC5-t002, ST72/CC5-t126, ST1/CC1-t127, ST45/CC45-t065, and ST398/t1451) could be related to epidemic clones, such as USA800/ST5, USA700/ST72, USA400/ST1, USA600/ST45, and ST398. This study made it possible to understand the characteristics of virulence and clonality of some strains that circulate in breast milk in our region. The discovery of human milk colonization by MSSA and MRSA strains with molecular characteristics similar to infectious clones spread globally demonstrates the importance of monitoring strains that can spread and cause serious infections.Antibiotics and other antimicrobial compounds are the backbone of clinical medicine. Antimicrobial resistance can cause serious diseases to man. Nanotechnology can improve therapeutic potential of medicinal molecules and related agents. Widespread application of antibiotics and other antimicrobial compounds led to development of multidrug-resistant microbes, so there is need to develop novel therapeutic agents. Novel synthesized nanometric delafossite was assayed against two Gram-positive bacteria (Staphylococcus aureus and Micrococcus luteus), two Gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae), four opportunistic fungi (Aspergillus flavus, A. fumigatus, A. niger, and Fusarium solani), and four Candida species (C. albicans, C. parapsilosis, C. krusei, and C. tropicalis) using diffusion assay method. The minimum inhibitory concentration (MIC) of the novel synthesized nanometric delafossite was determined using the dilution method. The assayed compounds showed different degrees of antifungal and antibacterial activities, depending on the annealing temperature of preparation of these compounds. Compounds prepared at room temperature showed greater antimicrobial activities than those prepared at higher temperatures. The antimicrobial activity depends also on the susceptibility of the test microbe.
Acute coronary syndrome is a major health problem affecting ~1.5 million individuals a year in the USA. We review the contemporary role of anti-anginal and anti-ischemic therapies in the management of an individual presenting with an acute coronary syndrome.
Early diagnosis and appropriate evidence-based therapies significantly improve clinical outcomes in acute coronary syndrome patients. Typically, acute coronary syndrome is associated with rupture of an atherosclerotic plaque and either partial or complete thrombotic occlusion of a coronary artery. Management of an acute coronary syndrome is targeted towards this underlying pathophysiology. The last few years have seen significant advances in anti-anginal and anti-ischemic therapies in the management of patients with acute coronary syndrome. It is important to have a team effort to target risk reduction measures and to emphasize medication and dietary compliance. Long-term pharmacotherapy should include aspirin, beta-blocker, DAPT (for at least 1year), statins, and ACE inhibitors and PCSK9 inhibitors if indicated.
