We studied sex-related differences in gamma oscillation during an auditory oddball task, using magnetoencephalography and electroencephalography assessment of imaginary coherence (IC). We obtained a statistical source map of event-related desynchronization (ERD) / event-related synchronization (ERS), and compared females and males regarding ERD / ERS. Based on the results, we chose respectively seed regions for IC determinations in low (30-50 Hz), mid (50-100 Hz) and high gamma (100-150 Hz) bands. In males, ERD was increased in the left posterior cingulate cortex (CGp) at 500 ms in the low gamma band, and in the right caudal anterior cingulate cortex (cACC) at 125 ms in the mid-gamma band...

Emotional behavior is an active area of study in the fields of neuroscience and affective computing. This field has the fundamental role of emotion recognition in the maintenance of physical and mental health. Valence/Arousal levels are two orthogonal, independent dimensions of any emotional stimulus and allows an analysis framework in affective research. In this paper we present our framework for emotional regression based on machine learning techniques. Autoregressive coefficients and hidden markov models on physiological signals, based on Fisher Kernels characterization are presented for mapping variable length sequences to new dimension feature vector space...

Host colonization by lymphotropic γ-herpesviruses depends critically on expansion of viral genomes in germinal center (GC) B-cells. Myc is essential for the formation and maintenance of GCs. Yet, the role of Myc in the pathogenesis of γ-herpesviruses is still largely unknown. In this study, Myc was shown to be essential for the lymphotropic γ-herpesvirus MuHV-4 biology as infected cells exhibited increased expression of Myc signature genes and the virus was unable to expand in Myc defficient GC B-cells. We describe a novel strategy of a viral protein activating Myc through increased protein stability resulting in increased progression through the cell cycle...

Although the implementation of acute geriatric units (AGUs) in general hospitals has a grade A of evidency, in Spain, only 12% of them have this resource. The estimation of geriatric especializad beds for the care of acute frail elderly people is of 2.6/1000 inhabitants older than 75 years. AGUs have demonstrated to reduce the functional loss associated with the hospitalization and to increase the percentage of older people that can return home, without increases in mortality nor costs. In this review we present the characteristics of patients who benefit from AGUs, the services offered, the structure and functioning of the unit, the role of the professionals that work in it and the quality indicators that must be acomplished...

Meningiomas in childhood are rare, and those located in the third ventricle are even rarer, with only 16 cases reported. A five-year-old girl was seen at our hospital with headache and bilateral papilledema. CT scan showed a large third ventricular mass and associated hydrocephalus. Transcallosal interfornical approach was performed with total removal of the tumor, that was attached to the choroid plexus of the anterior third ventricle. Histologically the lesion proved to be a transitional meningioma. The recovery was uneventful, a permanent shunt was not necessary...

In the early 1990s, a series of outbreaks of hepatitis C (HCV) infections clustering among recipients of certain lots of plasma-derived medicinal products (PDMP) alarmed regulatory authorities, manufacturers and the public alike. Also, a few episodes of Hepatitis A (HAV) infections occurred in haemophiliacs receiving solvent-detergent-treated factor VIII concentrates. Thus, several measures were brought into effect to reestablish the safety of the incriminated products and to further increase the margin of safety of PDMP in general...

Large areas of photoreceptor membrane are synthesized in the retinula cells of the crab Leptograpsus variegatus at dusk. Initially, new membrane differentiates from rough endoplasmic reticulum (ER) as large tubules of smooth ER. These tubules transform to concentric ellipsoids of closely apposed pairs of membranes ("doublet ER"), sometimes passing through an intervening crenate form. The new membrane is transported through bridges of cytoplasm that cross the palisade to the rhabdom region, from which the remains of the rhabdomeres that were built during the previous dusk have been dissolved...
