Introduction: In the present work, spontaneous postsynaptic currents were assessed to investigate the postnatal development of excitatory postsynaptic currents in locus coeruleus neurons. Methods: In this study, AMPA and NMDA receptor-mediated spontaneous synaptic currents in the neurons of locus coeruleus were assessed using whole cell voltage-clamp recording during the first three weeks. ...

Purpose: Morphological dental anomalies of the maxillary lateral incisors are relatively common. However, their simultaneous occurrence is a relatively rare event. We report a case of dens invaginatus and talon cusp concurrently affecting maxillary lateral incisors. The etiology, pathophysiology, association with other dental anomalies, as well as various treatment modalities of these anomalies...

ground penetrating radar (gpr) is one of high resolution geophysical methods for locating missed objects, buried equipments. gpr is a nondestructive testing method that is useful in various kinds of explorations such as mapping the archaeological sites. the safety of the archaeological sites is one of the most concerns of the archaeologists. one of the best gpr applications is in archaeology as...

[1] Earth’s inner radiation belt located inside L= 2 is dominated by a relatively stable flux of trapped protons with energy from a few to over 100 MeV. Radiation effects in spacecraft electronics caused by the inner radiation belt protons are the major cause of performance anomalies and lifetime of Low Earth Orbit satellites. For electronic components with large feature size, of the order of a...

introduction robinow syndrome (rs) is an infrequent genetic condition that is characterized by a dysmorphic face, dental anomaly, short stature, mesomelic limb shortening, hand and foot anomalies, and hypoplastic genitalia. the robinow syndrome has been reported from the arab countries and other asian countries, but has not been reported in iranian population so far. case presentation a new bor...

This paper studies multiple regimes and low-frequency oscillations in the Northern Hemisphere zonal-mean zonal flow in winter, using 55 years of daily observational data. The probability density function estimated in the phase space spanned by the two leading empirical orthogonal functions exhibits two distinct, statistically significant maxima. The two regimes associated with these maxima desc...

Whether there is an independent component of MJO associated with El Niño Southern Oscillation (ENSO) is investigated using Xie-Arkin precipitation and NCEP reanalysis pentad data. The analysis tool employed here is the cyclostationary empirical orthogonal function (CSEOF) technique. As a result of the analysis, the evolution of the precipitation pattern for the Asian-Pacific domain is found to ...

We present photometry of 4 transits of the exoplanet WASP-4b, each with a precision of approximately 500 ppm and a time sampling of 40-60 s. We have used the data to refine the estimates of the system parameters and ephemerides. During two of the transits we observed a short-lived, low-amplitude anomaly that we interpret as the occultation of a starspot by the planet. We also found evidence for...

Patients with Primary Progressive Aphasia (PPA) may react to linguistic stimuli differently than healthy controls, reflecting degeneration of language networks and engagement of compensatory mechanisms. We used magnetoencephalography (MEG) to evaluate oscillatory neural responses in sentence comprehension, in patients with PPA and age-matched controls. Participants viewed sentences containing s...

Abstract Previous theoretical work has suggested that the strength of divergent eddy momentum flux in deep tropics, due to correlations between rotational zonal velocities and meridional velocities, increases with tilt large-scale divergence field. To test idea, this investigates interannual variability reanalysis data. Consistent theory, it is found driven by two main parameters: amplitude tro...
