BACKGROUND Pneumocystis jirovecii causes Pneumocystis pneumonia (PCP) in immunocompromised patients with a high rate of morbidity and mortality. Colonization with this fungus may stimulate pulmonary inflammation or lead to PCP in susceptible patients. The epidemiology of this infection and routs of its transmission has poorly studied in Iran. We examined(More)
AIMS Minor head injury (MHI) is a common injury seen in Emergency Departments (ED). Computed tomography (CT) scan of the brain is a good method of investigation to diagnose intracranial lesions, but there is a disagreement about indications in MHI patients. We surveyed the post-traumatic symptoms, signs or past historical matters that can be used for the(More)
— In this paper, the problem of multi-vehicle cooperative interception of moving objects with unknown arrival times, trajectories and dynamics is investigated. The vehicles are assumed to have limited sensing and communication ranges. Therefore centralized approaches are not efficient, especially for the case of large number of vehicles and targets. In this(More)
BACKGROUND Pulmonary aspergillosis (PA) is one of the most serious complications in immunocompromised patients, in particular among hematopoietic stem cell transplants (HSCT) and patients with hematological malignancies. OBJECTIVES The current study aimed to evaluate the incidence of PA and utility of molecular methods in HSCT and patients with(More)
Invasive aspergillosis continues to be a significant cause of morbidity and mortality in solid organ transplant (SOT) recipients. A reliable and early diagnostic method is needed to improve survival. In this study, four methods direct microscopy, culture, nested PCR on internal transcribed spacer region, and TaqMan real-time PCR targeted β-tubulin gene were(More)
BACKGROUND Non-dermatophyte onychomycosis (NDO) is caused by a wide range of mold fungi other than dermatophytes, and has been reported at various rates in different countries worldwide. Studies on the incidence of NDO in the community are essential for understanding its epidemiology and control, as well as for the appropriate treatment of these infections.(More)
BACKGROUND PCR has been used for confirmation of leishmaniasis in epidemiological studies, but complexity of DNA extraction and PCR approach has confined its routine use in developing countries. OBJECTIVES In this study, recent epidemiological situation of cutaneous leishmaniasis (CL) in two hyper-endemic metropolises of Shiraz and Isfahan in Iran was(More)
Ultrasound elastography involves measuring the mechanical properties of tissue, and has many applications in diagnostics and intervention. A common step in different elastography methods is imaging the tissue while it undergoes deformation and estimating the displacement field from the images. A popular next step is to estimate tissue strain, which gives(More)
In this paper, the Maximum Reward Collection Problem (MRCP) in uncertain environments is investigated where multiple agents cooperate to maximize the total reward collected from a set of moving targets in the mission space with unknown arrival times, trajectories and dynamics. The reward with respect to each of the targets has a time discounting value and(More)
