Stromal cells of giant cell tumor of bone show primary cilia in giant cell tumor of bone.

Giant cell tumor of bone (GCTB) is a locally aggressive primary bone neoplasm composed by tumoral stromal cells (SCs) and a reactive component that consists of monocytic/histiocytic cells that give rise by fusion to osteoclast-like multinucleated cells. Recently, specific Histone 3.3 mutations have been demonstrated in SCs of GCTB.

A Semiconductor Chip-Based Next Generation Sequencing Procedure for the Main Pulmonary Hypertension Genes.

The aim of this study was to characterize the mutational spectrum of pulmonary hypertension (PH) patients through a next generation sequencing platform. In a total of 22 patients, the BMPR2, SMAD9, CAV1, KCNK3, and EIF2AK4 genes were sequenced with semiconductor chips and the ion torrent personal genome machine. We found six putative mutations in SMAD (p.

Effects of region of birth, educational level and age on late presentation among men who have sex with men newly diagnosed with HIV in a network of STI/HIV counselling and testing clinics in Spain.

This paper analyses late presentation (LP) of HIV infection, and its determinants, among men who have sex with men (MSM) in Spain, newly diagnosed with HIV (2003-2011) in 15 sexually transmitted infection/HIV counselling and testing clinics. LP was defined as <350 CD4 cells/µL or AIDS. In total, 3,081 MSM were included (2,499 having CD4/AIDS); overall LP was 25.
