Armoured dinosaurs are well known for their evolution of specialized tail weapons-paired tail spikes in stegosaurs and heavy tail clubs in advanced ankylosaurs1. Armoured dinosaurs from southern Gondwana are rare and enigmatic, but probably include the earliest branches of Ankylosauria2-4. Here we describe a mostly complete, semi-articulated skeleton of a small (approximately 2 m) armoured dinosaur from the late Cretaceous period of Magallanes in southernmost Chile, a region that is biogeographically ...

Abstract Aim The aim of this study was to assess the effectiveness of sacral nerve stimulation (SNS) in the management of faecal incontinence following neoadjuvant therapy and low anterior resection (LAR) for rectal cancer. Method In a prospective single‐centre study, 15 patients (12 men, median age 72 years) were enrolled between 2005 and 2008. All had severe incontinence after total mesorectal excision, and 14 had received preoperative full‐course chemoradiotherapy. The patients were followed up ...

The aim of this prospective observational study was to compare the quality of total mesorectal excision between laparoscopic and open surgery for rectal cancer.In April 2006, the Spanish Association of Surgeons started an audited teaching programme. The project was similar to the Norwegian one and several training courses were arranged. Patients were classified into two groups: laparoscopic rectal resection (LR) and open rectal resection (OR). The quality of the mesorectum was scored: complete, nearly ...

Context: Neurobiological models of obsessive-compulsive disorder (OCD) emphasize disturbances in the function and connectivity of brain corticostriatal networks, or "loops."Although neuroimaging studies of patients have supported this network model of OCD, very few have applied measurements that are sensitive to brain connectivity features.Objective: Using resting-state functional magnetic resonance imaging, we tested the hypothesis that OCD is associated with disturbances in the functional connectivity ...

The present investigation was devoted to unraveling the time-course and brain regions involved in speech segmentation, which is one of the first processes necessary for learning a new language in adults and infants. A specific brain electrical pattern resembling the N400 language component was identified as an indicator of speech segmentation of candidate words. This N400 trace was clearly elicited after a short exposure to the words of the new language and showed a decrease in amplitude with longer ...

BackgroundSocial anxiety often involves a combination of hypervigilance and avoidance to potentially warning signals including the facial expression of emotions. Functional imaging has demonstrated an increase in amygdala response to emotional faces in subjects with social anxiety. Nevertheless, it is unclear to what extent visual areas processing faces influence amygdala reactivity in different socially anxious individuals. We assessed the influence of the fusiform gyrus activation on amygdala ...

Nociceptive stimuli may evoke brain responses longer than the stimulus duration often partially detected by conventional neuroimaging. Fibromyalgia patients typically complain of severe pain from gentle stimuli. We aimed to characterize brain response to painful pressure in fibromyalgia patients by generating activation maps adjusted for the duration of brain responses.Twenty-seven women (mean age: 47.8 years) were assessed with fMRI. The sample included nine fibromyalgia patients and nine healthy ...

However, there is no information about the effect of dementia on driving habits in non‐industrialized countries. The number of motor vehicle crashes (MVC) and abnormal driving behaviours (ADB) (e.g. not recognizing traffic lights, driving in the middle of the road, etc.) were assessed with a semi‐structured interview in 56 demented subjects and 31 elderly controls, all of whom ...

The value of programs to detect recurrence of a previously operated gastric cancer is a controversial subject. D2 lymphadenectomy achieves better local control and a lower local recurrence rate than D1 lymphadenectomy.The results achieved with surgical treatment of recurrent gastric cancer in a series of 126 consecutive patients who had been treated with gastrectomy with D2 lymphadenectomy are reported. In-hospital mortality was 1.6%.Follow-up of the remaining 124 patients for a median period of ...

There is growing interest in the nature of slow variations of the blood oxygen level-dependent (BOLD) signal observed in functional MRI resting-state studies. In humans, these slow BOLD variations are thought to reflect an underlying or intrinsic form of brain functional connectivity in discrete neuroanatomical systems. While these 'resting-state networks' may be relatively enduring phenomena, other evidence suggest that dynamic changes in their functional connectivity may also emerge depending on ...

The notion of a “default mode of brain function” has taken on certain relevance in human neuroimaging studies and in relation to a network of lateral parietal and midline cortical regions that show prominent activity fluctuations during passive imaging states, such as rest. In this study, we perform three fMRI experiments that demonstrate consistency and specialization in the default mode network. Correlated activity fluctuations of default mode network regions are identified during ( i ) eyes-closed ...

In the surgical management of gastric cancer, D2 lymphadenectomy aims to reduce the incidence of locoregional relapse, and to increase patient survival. A prospective study was made of 126 consecutive patients operated upon for gastric cancer, with gastrectomy and D2 lymphadenectomy. Hospital morbidity and mortality, relapses, and patient survival after 5 years were studied. The overall hospital mortality rate was 1.6%, with a mortality of 2.1% in the patients submitted to total gastrectomy. The ...

Abstract Previous neuroimaging studies have suggested that children with specific language impairment (SLI) may show subtle anatomical alterations in specific brain regions. We aimed to characterize structural abnormalities in children with SLI using a voxel‐wise analysis over the whole brain. Subjects covered a wide age range (5–17 years) in order to assess the dynamic nature of the disorder across childhood. Three‐dimensional MRIs were collected from 36 children with SLI and from a comparable group ...

Major depressive disorder (MDD) is characterized by a constellation of affective, cognitive, and somatic symptoms associated with functional abnormalities in relevant brain systems. Painful stimuli are primarily stressful and can trigger consistent responses in brain regions highly overlapping with the regions altered in MDD patients.
