Investigating Cognitive Load in Energy Network Control Rooms: Recommendations for Future Designs.

This study analyzed and explored the cognitive load of Australian energy market operators managing one of the longest inter-connected electrical networks in the world. Each operator uses a workstation with seven screens in an active control room environment, with a large coordination screen to show information and enable collaboration between different control centers. Cognitive load was assessed during both training scenarios and regular control room operations via the integration of subjective and physiological measures.

Analysis of RAS gene mutations in cytogenetically normal de novo acute myeloid leukemia patients reveals some novel alterations.

Rat sarcoma gene (RAS) holds great importance in pathogenesis of acute myeloid leukemia (AML). The activated mutations in Neuroblastoma rat sarcoma viral oncogene homolog (NRAS) and Kirsten rat sarcoma viral oncogene homolog (KRAS) confers proliferative and survival signals, deliberating numerous effects on overall survival and progression free survival in AML patients. In this study thirty one (31) blood samples of adult newly diagnosed AML patients were collected to identify possible incidence of mutations through amplification of KRAS (exon 1 and 2) and NRAS gene (exon 1 and 2) using polymerase chain reaction (PCR).

Sleep in Neuromuscular Diseases.

Sleep disorders in neuromuscular disorders are generally caused by respiratory dysfunction associated with these diseases. Hypoventilation in neuromuscular diseases results from both respiratory muscle weakness and reduced chemoreceptor sensitivity, which is required for ventilatory drive. This condition results in repeated arousals, sleep fragmentation, and nocturnal hypoxemia, manifesting most commonly as excessive daytime somnolence.
