Burkitt's lymphoma revealed by intestinal obstruction: A case report.

Intestinal obstruction is a surgical emergency frequently encountered in routine practice, usually caused by abdominal adhesions. Although extra nodal lymphoma is most often localized in the gastrointestinal tract and may be responsible for intestinal obstruction, Burkitt's lymphoma is a very rare cause in adults. We report a case of Burkitt's lymphoma mimicking an intestinal obstruction in a 48-year-old adult who presented with an obstructive syndrome and altered general condition.

Social facilitation and bilingual cognitive advantage: Bridging social psychology and psycholinguistics.

This study examined the role of social context in the expression of the bilingual cognitive advantage in 145 bilingual university students. All participants mastered Arabic as their native language (L1), but half were highly proficient in French (high L2 group), whereas half were less proficient (low L2 group). A color-word Stroop test with incongruent, congruent and neutral stimuli was administered in single language blocks (Arabic or French words) or in a mixed block (Arabic and French words), either under social presence, or alone.

Emotion processing in Parkinson's disease: a blood oxygenation level-dependent functional magnetic resonance imaging study.

Parkinson's disease is a neurodegenerative disorder caused by loss of dopamine neurons in the substantia nigra pars compacta. Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade.
