NAMD is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD scales to hundreds of processors on high-end parallel platforms, as well as tens of processors on low-cost commodity clusters, and also runs on individual desktop and laptop computers. NAMD works with AMBER and CHARMM potential functions, parameters, and file formats. This art...

PURPOSE We have previously documented that neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) have multiple different clinical and genetic characteristics. In this study, we investigated the association of rs42524 in the alpha-2 type I collagen (COL1A2) gene, which has been identified as a risk variant for intracranial aneurysm, with nAMD and PCV in ...

2 Summary NAMD is a molecular dynamics program designed for high performance simulations of large biomolecular systems on parallel computers. An object-oriented design implemented using C++ facilitates the incorporation of new algorithms into the program. NAMD uses spatial decomposition coupled with a multithreaded, message-driven design which is shown to scale eeciently to multiple processors....

Toll-like receptor 3 (TLR3) variants in mainland northern Chinese patients with polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (nAMD) were investigated. The complete genes of TLR3, including all exons and the promoter region, were assessed using direct sequencing technology of 284 unrelated mainland northern Chinese individuals: 96 nAMD patients, 92 PCV...

PURPOSE Age-related macular degeneration (AMD) is the main cause of visual impairment and legal blindness in older individuals. COL8A1 rs13095226 variants have recently been implicated associated with neovascular age-related macular degeneration (nAMD) and Polypoidal Choroidal Vasculopathy (PCV) in American studies. The aim of this study was to investigate the association between the COL8A1 rs1...

PURPOSE To investigate whether Met72Thr (rs1136287), a common single nucleotide polymorphism (SNP) variant of the pigment epithelium-derived factor (PEDF) gene, is associated with neovascular age-related macular degeneration (nAMD) or polypoidal choroidal vasculopathy (PCV) in a Han Chinese cohort. METHODS We genotyped Met72Thr (rs1136287) in persons of Han Chinese descent: 177 PCV patients, ...

Neovascular age-related macular degeneration (nAMD) is the leading cause of irreversible blindness in developed countries. Recent advances have highlighted the essential role of inflammation in the development of the disease. In addition to local retinal chronic inflammatory response, systemic immune alterations have also been observed in AMD patients. In this study we investigated the associat...

BACKGROUND Immune responses play a key role in the pathogenesis and progression of polypoidal choroidal vasculopath (PCV) and age-related macular degeneration (AMD). In this study, we determined the Th cell-associated immune responses by measuring the cytokine expression of peripheral blood mononuclear cells (PBMC) in both PCV and neovascular AMD (nAMD) patients. METHODS Twenty-seven nAMD pat...

Neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) are both major serosanguinous maculopathies among the Asian elderly. They are similar in phenotype. Genetic variants in high-density lipoprotein (HDL) pathway were discovered to be associated with AMD in two genome-wide association studies. In this study with a Chinese Han cohort, we investigated the...

PURPOSE To investigate the effect of genetic variants in the high-density lipoprotein (HDL) metabolic pathway and risk factors on neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) in China. METHODS A total of 742 Chinese subjects, including 221 controls, 230 cases with nAMD, and 291 cases with PCV, were included in the present study. Five single n...
