Neurobiological studies demonstrate the amygdala’s role in emotional memory, and psychological studies suggest a particular pattern: enhanced memory for the gist but not the details of complex stimuli. We hypothesized that these two findings are related. Whereas normal (n 5 52) and brain-damaged (n 5 22) controls showed the expected enhancement of gist memory when the encoding context was emoti...

Shape oen has a decisive inuence over the properties and applications of monodisperse nanoparticles. In addition, size is another important factor controlling the properties of the nanomaterials owing to various connement effects. Therefore, the synthesis of diverse, high-quality nanoparticles with tunable shapes and sizes has become a challenging issue and drawn considerable attention. Morp...

INTRODUCTION Recent data indicates that low vitamin D (25(OH)D) levels can lead to a worst prognosis in HIV-infected individuals, even in those on successful antiretroviral therapy (ART) [1]. Portugal is the European country that has the largest average sun exposure time but prevalence of hypovitaminosis D is mostly unknown. Our aim was to determine the prevalence of hypovitaminosis D in HIV pa...

Neurons have been neglected as cells with a major immune-regulatory function because they do not express major histocompatibility complex class II. Our data show that neurons are highly immune regulatory, having a crucial role in governing T-cell response and central nervous system (CNS) inflammation. Neurons induce the proliferation of activated CD4+ T cells through B7-CD28 and transforming gr...

The light-induced absorbance change at 518 nm of isolated chloroplasts consists of a rapid phase, and a slow phase which is complete in about 20 sec. The slow component of the 518 nm absorbance change correlates with the light-induced change in 90 degrees light scattering at 518 nm. Both show a similar time course, similar pH dependence with a maximum at pH 6.0, and similar sensitivity to inhib...
