Objective To compare the diagnostic performance of three-dimensional (3D) positron emission mammography (PEM) versus whole body positron emission tomography (WBPET) for breast cancer. Methods A total of 410 women with normal breast or benign or highly suspicious malignant tumors were randomized at 1 : 1 ratio to undergo 3D-PEM followed by WBPET or WBPET followed by 3D-PEM. Lumpectomy or maste...
The quality of pediatric emergency care may depend on the competence of the emergency department physicians. It is important to know whether parents and general pediatricians associate the quality of pediatric emergency care with the pediatric emergency medicine (PEM) training of the emergency department physicians. We designed the study to determine parental and pediatricians' opinion and expe...
The state of pediatric emergency medicine (PEM) education within emergency medicine (EM) residency programs is reviewed and discussed in the context of shifting practice environments and new demands for a greater focus on the availability and quality of PEM services. The rapid growth of PEM within pediatrics has altered the EM practice landscape with regard to PEM. The authors evaluate the comp...
Aflatoxins are natural contaminants of food crops implicated in the pathogenesis of various human diseases. This study aimed to determine the associations between aflatoxins and proteinenergy malnutrition (PEM) by measurements of aflatoxins in serum, urine and food on plate of Nigerian children with PEM. A crosssectional study was undertaken in 3 agroecological regions of Nigeria (Guinea savann...
Previous study has shown that the anti-Hu antibody titre of serum samples from patients with paraneoplastic encephalomyelitis/paraneoplastic sensory neuronopathy (PEM/PSN) was significantly higher than that from patients with small cell lung cancer without neurological disturbances (non-PEM/PSN). The aims of this study were (1) to identify the fine epitopes on HuD recognised by the anti-Hu anti...
UNLABELLED Early detection of breast cancer is crucial for efficient and effective treatment. We have developed an instrument for positron emission mammography (PEM) called PEM-I that performs high-resolution metabolic imaging of breast cancer. Images of glucose metabolism are obtained after injection of 75 MBq FDG. The PEM detectors are integrated into a conventional mammography system, allowi...
This paper considers modeling and simulation study of a fuel cell system. A mathematical model of a Polymer Electrolyte Membrane (PEM) Fuel Cell system is presented in this paper. For the convenience of presentation, cathode flow, anode flow, the membrane hydration, and voltage output expressions of the PEM fuel cell system are given in the paper to bridge a generic model to the model of Fuel C...
The development of polymer electrolyte membrane (PEM) fuel cells that can be operated over a wide temperature range without the need for humidification is highly desirable for vehicle applications to overcome the problems associated with CO poisoning and water management. Here we report a novel PEM based on 1H-1,2,4-triazole grafted polysiloxane doped with phosphoric acid and reinforced with po...
We aimed to elucidate the incidence of protein–energy malnutrition (PEM) in patients with chronic liver disease and to identify factors linked to the presence of PEM. A total of 432 patients with chronic liver disease were analyzed in the current analysis. We defined patients with serum albumin level of 3.5 g/dL and nonprotein respiratory quotient (npRQ) value using indirect calorimetry less th...
INTRODUCTION PRONOUNCE compared the efficacy and safety of pemetrexed+carboplatin followed by pemetrexed (Pem+Cb) with paclitaxel+carboplatin+bevacizumab followed by bevacizumab (Pac+Cb+Bev) in patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). METHODS Patients ≥18 years of age with stage IV nonsquamous NSCLC (American Joint Committee on Cancer v7.0), and Eastern Cooperati...
