RESUMEN

Optical coherence tomography angiography (OCTA), as a new generation of non-invasive and efficient fundus imaging technology, can provide non-invasive assessment of vascular lesions in the retina and choroid. In terms of anatomy and development, the retina is referred to as an extension of the central nervous system (CNS). CNS diseases are closely related to changes in fundus structure and blood vessels, and direct visualization of fundus structure and blood vessels provides an effective "window" for CNS research. This has important practical significance for identifying the characteristic changes of various CNS diseases on OCTA in the future, and plays a key role in promoting early screening, diagnosis, and monitoring of disease progression in CNS diseases. This article reviews relevant fundus studies by comparing and summarizing the unique advantages and existing limitations of OCTA in various CNS disease patients, in order to demonstrate the clinical significance of OCTA in the diagnosis and treatment of CNS diseases.

RESUMEN

INTRODUCTION: One of the most common conditions that causes permanent blindness globally is age-related macular degeneration (AMD). The purpose of the present study was to determine the association between vitamin B1 consumption and the prevalence of late AMD in a representative US sample. METHODS: Data from the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2008 were utilized for this cross-sectional analysis. The logistic regression model was used to evaluate the association between vitamin B1 consumption levels and late AMD. RESULTS: Our study included 5,107 people aged 40 years old and above. Vitamin B1 intake levels were inversely associated with the prevalence of late AMD, with OR being 0.40 (95% CI: 0.26-0.62), 0.53 (95% CI: 0.29-0.94), 0.55 (95% CI: 0.31-0.99) for the crude model 1, adjusted model 2, and fully adjusted model 3, respectively. CONCLUSION: Our study found that vitamin B1 intake levels were inversely associated with the prevalence of late AMD in the USA. Further randomized clinical trials among multiple centers are still warranted to investigate the longitudinal and causal relationship between vitamin B1 intake and late AMD.

RESUMEN

Hierarchical metal nanostructures which exhibit an open structure and a high density of twin defects accessible to reactants hold great promise in catalysis. Here, we report a facile synthesis of Pt-Cu hierarchical quasi great dodecahedrons (HQGDs) which present 5-fold symmetry and are composed of multiple ordered branched units with a frame structure. HQGDs evolve from icosahedral seeds with multiple {111} twin planes, followed by the growth of higher-order branches. Owing to the unique frame structure associated with multiple twin defects, HQGDs showed much higher HER catalytic activity and better durability relative to commercial Pt/C.
