Electroencephalography is the only clinically available technique that can address the premature neonate normal and pathological functional development week after week. The changes in the electroencephalogram (EEG) result from gradual structural and functional modifications that arise during the last trimester of pregnancy. Here, we review the structural changes over time that underlie the establishment of functional immature neural networks, the impact of certain anatomical specificities (fontanelles, connectivity, etc.) on the EEG, limitations in EEG interpretation, and the utility of high-resolution EEG (HR-EEG) in premature newborns (a promising technique with a high degree of spatiotemporal resolution). In particular, we classify EEG features according to whether they are manifestations of endogenous generators (i.e. theta activities that coalesce with a slow wave or delta brushes) or come from a broader network. Furthermore, we review publications on EEG in premature animals because the data provide a better understanding of what is happening in premature newborns. We then discuss the results and limitations of functional connectivity analyses in premature newborns. Lastly, we report on the magnetoelectroencephalographic studies of brain activity in the fetus. A better understanding of complex interactions at various structural and functional levels during normal neurodevelopment (as assessed using electroencephalography as a benchmark method) might lead to better clinical care and monitoring for premature neonates.Two legacy AmLi sources have been actively used across several projects within Pacific Northwest National Laboratory, however, applicability of source measurement data has been substantially limited due to the lack of original manufacturer documentation and cross comparison to other sources. This paper summarizes measurements conducted to better quantify source radionuclide content, neutron energy spectrum and emission rate of the AmLi sources. Selleckchem BMS309403 The measured neutron energy spectra of AmLi sources produced by Monsanto Research Corporation have not been found in open literature before and therefore the focus of the study was to obtain the high definition energy distribution of the sources. The initial gamma spectrometry measurements, aimed to estimate the radionuclide content and potential impurities, revealed a significant contamination of the source material with beryllium. Consequent neutron spectrum measurements confirmed beryllium contamination through the presence of a high energy tail contributing up to 17% to the total neutron emission rate. The obtained lithium-only portion of the measured source energy distribution was compared against other AmLi spectra discussed in the past and recent literature. Determination of the total neutron yields of the sources was made with measurements in a neutron well counter. Detection efficiency of the well counter was calculated specifically for these sources via detailed Monte Carlo simulations based on the obtained neutron energy distribution.A 71-year-old man with Chagas disease and stable angina on minimum exertion underwent coronary computed tomography angiography and cine angiography that revealed heavily calcified multivessel disease involving the left main artery (LM). Due to the degree of calcification, it was decided to perform rotablation. The first-stage percutaneous coronary intervention (PCI) with rotablation was performed on the LM, left anterior descending artery and second diagonal branch without complications. Almost 30 days later he returned for right coronary artery (RCA) PCI. The proposed strategy was rotational atherectomy in the posterior descending artery (PDA) and right posterolateral artery (RPLA) with a 1.5 mm burr, followed by implantation of two drug-eluting stents (DES). Through right femoral artery access the RPLA lesion was ablated with success. As there were no signs of dissection and TIMI 3 flow was maintained, the 0.009″ RotaWire was repositioned to cross the PDA lesion and debulking of the lesion was performed. After two attempts we succeeded in crossing the lesion with the 1.5 mm burr, however entrapment of the burr ensued. The system was pulled back until the guiding catheter penetrated deep into the RCA, and attempts were made to release the Rotablator by moving it forward and backward, but the burr did not even spin. The contralateral femoral artery was therefore punctured and a 6F JR guiding catheter was inserted, in order to move a guidewire and small angioplasty balloon tangentially to the burr, but without success. Finally we advanced the guidewire using the 'knuckle' technique, taking advantage of the kinking of the distal portion of the PT2 guidewire, performing a subintimal dissection and re-entry, and could then easily cross the balloon, inflate it and release the trapped burr. Through the 6F system, two programmed and one bailout DES were successfully implanted in the PDA, RPLA and RCA, obtaining final TIMI 3 flow without complications.Driving under the influence of alcohol (DUIA) and drugs (DUID) is considered an elevated risk for traffic safety. When assessing a driver's fitness to drive, standardized and objective measurement methods are still required, in order to clarify the question whether an individual is under the influence of substances acting on the central nervous system (CNS). We exposed healthy test subjects (n=41) as well as persons who were under the influence of cannabis after repeated inhalation to multiple light stimuli using infrared technology and measured the pupillary light reflex (PLR). Toxicological tests of blood samples taken from every subject followed. The aims of this study were to assess the differences in pupillography response between cannabis consumers after a washout period and no cannabis consumers as well as the dose related effects on pupillography parameters of cannabis in cannabis consumers. All four pupillary parameters changed according to a weakened pupil function after acute administration of cannabis in all test subjects. Furthermore, it could be observed that habitual cannabis consumers showed an altered pupillary function just before the first dose was taken, suggesting that the long-term effects and addiction also have to be taken into account, when effects of the CNS are discussed. The results of the present study show that almost all pupil parameters could be reliable indicators for the detection of subjects under the acute effect of cannabis.
