It is suggested that the maternal transmission of islet autoantibodies increases the risk of autoimmune diabetes in mice. The aim of this study was to determine whether fetal exposure to islet autoantibodies modified the risk of type 1 diabetes in humans. Islet autoantibodies were measured at birth in 720 offspring of mothers with type 1 diabetes. Offspring were prospectively followed for the d...

Statistical background modeling is a standard technique for the detection of moving objects in a static scene. Nevertheless, the stateof-the-art approaches have several lacks for short sequences or quasi-stationary scenes. Quasi-static means that the ego-motion of the sensor is compensated by image processing. Our focus of attention goes back to the modeling of the pixel process, as it was intr...

Human natural killer (NK) cells are considered professional cytotoxic cells that are integrated into the effector branch of innate immunity during antiviral and antitumoral responses. The purpose of this study was to examine the peripheral distribution and expression of NK cell activation receptors from the fresh peripheral blood mononuclear cells of 30 breast cancer patients prior to any form ...

Most recent stereo algorithms are designed to perform well on close range stereo datasets with relatively small baselines and good radiometric conditions. In this paper, different matching costs on the Semi-Global Matching algorithm are evaluated and compared using aerial image sequences and satellite images with ground truth. The influence of various cost functions on the stereo matching perfo...

Bipolar disorder (BD) is a chronic and highly disabling mood disorder, associated with the highest suicide rate among psychiatric disorders. Even though neurobiological bases of BD have still to be further elucidated, recent neuroimaging studies provided compelling evidence about functional correlates of cognitive deficits in BD patients, with working memory (WM) impairment being one of the mos...

An Afro-American semi-isolated Colombian population is studied for its HLA genes: San Basilio de Palenque community in Colombia northern mountains. This community represents the first free Africans in America earning recognition by the Spanish Crown in 1691 AD. Nowadays, they also speak the only extant Bantu-Spanish Creole language over the World; these people have been apart from there neighbo...

Background/Aims: Anxious responses are evolutionarily adaptive, but excessive fear can become disabling and lead to anxiety disorders. Translational models of anxiety might be useful sources for understanding the neurobiology of fear and anxiety and can contribute to future proposals of therapeutic intervention for the disorders studied. Brain-derived neurotrophic factor (BDNF), which is known ...

Human Papillomaviruses (HPVs) are sexually transmitted pathogens, which are implicated in the etiology of cervical cancer. The early proteins E6 and E7 of HPV have transforming capacity and interfere with the cell cycle control of infected host cells and are essential for the maintenance of the transformed state. Identification of MHC class I-restricted, immunogenic peptides derived from either...

In this study, a large number of naturally processed peptides was isolated and identified from the human diabetes-susceptible class II MHC molecules HLA-DQ8 (DQA1*0301,DQB1*0302) and from murine I-A species, both of which are expressed in genetically identical APC lines. The peptides presented during the processing of autologous proteins were highly selective in showing sequence specificity, ma...
