Spatial separation of talkers is known to improve speech intelligibility in a multitalker scenario. A contribution of binaural unmasking, in addition to a better-ear effect, is usually considered to account for this advantage. Binaural unmasking is assumed to result from the spectro-temporally simultaneous...

Acute ethanol effects on neural encoding of reward size and delay in the nucleus accumbens

The role of expected reward in frontal eye field during natural scene search

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 1 ώρα
When a saccade is expected to result in a reward, both neural activity in oculomotor areas and the saccade itself (e.g. its vigor and latency) are altered (compared to when no reward is expected). As such, it is unclear whether the correlations of neural activity with reward indicate a representation of reward beyond a movement representation; the modulated neural activity may simply represent the differences in motor output due to expected reward. Here, to distinguish between these possibilities, we trained monkeys to perform a natural scene search task while we recorded from the... περισσότερα »

Shared and Distinct Retinal Input to the Mouse Superior Colliculus and Dorsal Lateral Geniculate Nucleus

The mammalian retina conveys the vast majority of information about visual stimuli to two brain regions: the dorsal lateral geniculate nucleus (dLGN) and the superior colliculus (SC). The degree to which retinal ganglion cells (RGCs) send similar or distinct information to the two areas remains unclear despite the important constraints that different patterns of RGC input place on downstream visual processing.

Αλέξανδρος ΣφακιανάκηςστοOtoRhinoLaryngology by Alexandros G.SfakianakisΠριν από 2 ώρες
Priming describes the principle of modified stimulus perception that occurs due to a previously presented stimulus. Although we have begun to understand the mechanisms of crossmodal priming, the concept of intramodal olfactory priming remains relatively unexplored. Therefore, we applied positive and negative odors using respiration-triggered olfactory stimulation (RETROS), enabling us to record the skin conductance response (SCR) and breathing data without a crossmodal cueing error and measure reaction times (RTs) for olfactory tasks. RT, SCR, and breathing data revealed that nega... περισσότερα »

Abstract Aim To investigate the bacterial microbiome in periodontal and peri-implant biofilms deriving from aggressive periodontitis patients (AgP) in conditions of health and disease. Material and methods Ninety-one plaque samples were collected from 18 patients previously diagnosed and treated for AgP. The samples were taken from (i) 24 residual periodontal pockets (TD) (*n = *6 patients), (ii) 24 healthy periodontal sites (TH) (*n = *6 patients), (iii) 24 dental sites from the same implant patients (TM) (*n = *6 patients), (iv) 5 peri-implantitis sites (II) (*n = *2 patients)... περισσότερα »

Feasibility and Advantage of a Muscle-Sparing Laterally Based Pericranial Flap

Alexandros G. SfakianakisστοΚοσμητική ΟδοντοΙατρική και ΓναθοΧειρουργικήΠριν από 2 ώρες
[image: image]Background: For a safe and reliable middle skull base reconstruction, the temporalis muscle flaps or pericranial-temporalis muscle flaps have usually been used as the first-choice in clinical practice. But these flaps have an inevitable disadvantage, namely, temporal hollowing. To address this problem, in this study, the authors describe the feasibility and advantages of using a muscle-sparing laterally based pericranial flap. Method: The authors reviewed 19 patients who had undergone middle skull base reconstruction using laterally based pericranial flaps. There were ...περισσότερα »

Huge Frontal-Temporal Lobe Arachnoid Cyst Presenting as an Weariness Migraine

[image: image]Abstract: To the authors' knowledge, most of intracranial arachnoid cyst located in middle cranial fossa and lateral fissure cistern. So, huge frontal-temporal lobe arachnoid cyst is rare. Symptoms of arachnoid cyst may be atypical, including headache, nausea, vomiting, epilepsy, poor memory, and so on. Of course, migraine related to weariness is a rare benign headache disorder. The authors reported a patient presenting with weariness migraine associated with large frontal-temporal lobe arachnoid cyst. from #ΓναθοΧειρουργική via xlomafota13 on Inoreader http://ift.tt/1... περισσότερα »

Bone Regeneration of the Maxillofacial Region Through the Use of Mesenchymal Cells Obtained by a Filtration Process of the Adipose Tissue

Alexandros G. SfakianakisστοΚοσμητική ΟδοντοΙατρική και ΓναθοΧειρουργικήΠριν από 2 ώρες
[image: image]Abstract: In this work, the authors will discuss about a new protocol and rapid alternative to isolate the mesenchymal stromal cells from the stromal vascular fraction, without the use of collagenase, to regenerate the bone tissue in the maxillo-facial region. This method employs a device that allows the isolation and concentration of stromal vascular fraction by means of lipoaspirates, which separate the lipid component and fragments of the extracellular matrix. The innovative element consists in using a filtration device instead of a centrifuging device to separate t... περισσότερα »

Polyurethane Foam-Filled Skull Replica of Craniosynostosis for Surgical Training

Alexandros G. SfakianakisστοΚοσμητική ΟδοντοΙατρική και ΓναθοΧειρουργικήΠριν από 2 ώρες
[image: image]Abstract: Craniosynostosis has a relatively low incidence in the general population and its treatment requires cautious approaches. For these reasons, patients are usually referred to several specialists or a medical center. Therefore, most trainees and young surgeons do not have any chances to experience patients of craniosynostosis, but learn about it only from textbooks. And for a surgeon who tries to operate on a craniosynostosis patient, it is hard to make a proper preoperative plan. The authors suggest a polyurethane foam-filled skull replica of craniosynostosis ... περισσότερα »

Formation of lipid bodies and fatty acid composition changes upon pre-akinete formation in arctic and Antarctic Zygnema (Zygnematophyceae, Streptophyta) strains

Alexandros G. SfakianakisστοΛοίμωξηΠριν από 2 ώρες
Filamentous green algae of the genus *Zygnema* (Zygnematophyceae, Streptophyta) are key components of polar hydro-terrestrial mats where they face various stressors including UV irradiation, freezing, desiccation and osmotic stress. Their vegetative cells can develop into pre-akinetes, i.e., reserve-rich, mature cells. We investigated lipid accumulation and fatty acid (FA) composition upon pre-akinete formation in an arctic and an Antarctic *Zygnema* strain using transmission electron microscopy (TEM) and gas chromatography coupled with mass spectrometry (GC-MS). Pre-akinetes form...περισσότερα »

Changes in microbial communities associated with gas hydrates in subseafloor sediments from the Nankai Trough

Alexandros G. SfakianakisστοΛοίμωξηΠριν από 2 ώρες
Little is known about the microbial distribution patterns in subseafloor sediments. This study examines microbial diversity and activities in sediments of the Nankai Trough, where biogenic gas hydrates are deposited. Illumina sequencing of 16S rRNA genes revealed that the prokaryotic community structure is correlated with hydrate occurrence and depth but not with the sedimentary facies. The bacterial phyla 'Atribacteria' lineage JS1 and *Chloroflexi* dominated in all samples, whereas lower taxonomic units of *Chloroflexi* accounted for community variation related to hydrate satura... περισσότερα »
