Parietal intrahemispheric source connectivity of resting-state electroencephalographic alpha rhythms is abnormal in Naïve HIV patients.

Previous evidence showed abnormal parietal sources of resting-state electroencephalographic (EEG) delta (< 4 Hz) and alpha (8-12 Hz) rhythms in treatment-Naïve HIV (Naïve HIV) subjects, as cortical neural synchronization markers in quiet wakefulness. Here, we tested the hypothesis that these local abnormalities may be related to functional cortical dysconnectivity as an oscillatory brain network disorder. The present EEG database regarded 128 Naïve HIV and 60 Healthy subjects.

Variability and abundance of the epiphytic bacterial community associated with a green marine Ulvacean alga.

Marine Ulvacean algae are colonized by dense microbial communities predicted to have an important role in the development, defense and metabolic activities of the plant. Here we assess the diversity and seasonal dynamics of the bacterial community of the model alga Ulva australis to identify key groups within this epiphytic community. A total of 48 algal samples of U.

[Spontaneous rupture of the spleen in non-hodgkin lymphoma: a case report].

Spontaneous rupture of the spleen without a history of trauma is a rare clinical entity and represents a dramatic abdominal emergency. Most cases of spontaneous rupture occur in a diseased spleen (pathological spontaneous rupture). The authors present the case of a 20-year-old man who presented with pain in the left upper quadrant and clinical signs of haemorrhagic shock.

Structure analysis and performance of a microbial community from a contaminated aquifer involved in the complete reductive dechlorination of 1,1,2,2-tetrachloroethane to ethene.

An anaerobic microcosm set up with aquifer material from a 1,1,2,2-tetrachloroethane (TeCA) contaminated site and amended with butyrate showed a complete TeCA dechlorination to ethene. A structure analysis of the microbial community was performed by fluorescence in situ hybridization (FISH) with already available and on purpose designed probes from sequences retrieved through 16S rDNA clone library construction. FISH was chosen as identification tool to evaluate in situ whether the retrieved sequences belong to primary bacteria responsible for the biodegradative reactions.
