    POSSIBILITIES FOR IMPROVEMENT OF RISK MANAGEMENT PRACTICES IN THE COAL MINING INDUSTRY OF THE FEDERATION OF BOSNIA AND HERZEGOVINA by Safet Kozarević, Adil Kurtić, Emira Kozarević

    Published 2014-11-01
    “…This particularly affects the coal industry, where risk exposure is rather evident and makes risk management one of the key management issues in general. A central point of the analysis includes companies in the coal industry of the Federation of Bosnia and Herzegovina (F BiH), where the management needs to be greatly concerned about protection against risks that affect this industry much more than other industries, in particular pure risks (those that involve only the possibility of loss and no possibility of gain). …”

    Systems-level analysis of NalD mutation, a recurrent driver of rapid drug resistance in acute Pseudomonas aeruginosa infection. by Jinyuan Yan, Henri Estanbouli, Chen Liao, Wook Kim, Jonathan M Monk, Rayees Rahman, Mini Kamboj, Bernhard O Palsson, Weigang Qiu, Joao B Xavier

    Published 2019-12-01
    “…A detailed analysis of one patient's timeline shows how this mutation can emerge in vivo and drive rapid evolution of resistance while the patient received cancer treatment, a bone marrow transplantation, and antibiotics up to the point of causing the patient's death. Transcriptomics analysis confirmed the primary mechanism of NalD action-a loss-of-function mutation that caused constitutive overexpression of the MexAB-OprM efflux system-which lead to aztreonam resistance but, surprisingly, had no fitness cost in the absence of the antibiotic. …”
