[Human facial shape related SNP analysis in Han Chinese populations].

Human facial morphology is one of the important visible biological characteristics. Understanding the genetic basis underlying facial shape traits has important implications in population genetics, developmental biology, and forensic science. This study extracted 136 Euclidean distance phenotypes from 17 facial features of high-resolution 3D facial images in 1177 Chinese Han adult males.

Heterogeneous Aging Effects on Functional Connectivity in Different Cortical Regions: A Resting-State Functional MRI Study Using Functional Data Analysis.

Brain aging is a complex and heterogeneous process characterized by the selective loss and preservation of brain functions. This study examines the normal aging effects on the cerebral cortex by characterizing changes in functional connectivity using resting-state fMRI data. Previous resting-state fMRI studies on normal aging have examined specific networks of the brain, whereas few studies have examined cortical-cortical connectivities across the entire brain.

[Application value of multiple phase subtraction imaging of dynamic contrast enhanced magnetic resonance imaging in common breast tumor].

Objective: To evaluate the application value of multiple phase subtraction imaging of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in common breast tumor.

Methods: All radiographic and MRI data of 72 patients with histological proved common breast tumor were analyzed retrospectively. Prior to an injection of gadolinium-diethylenetriaminepentaacetate (GD-DTPA), 3D mask scans were performed.

Asthma drugs counter-regulate interleukin-8 release stimulated by sodium sulfite in an A549 cell line.

Background: Clinical manifestations suggest that air pollution may induce deterioration of respiratory health. Some air pollutants, including sulfite, may play a role in the exacerbation of asthma. Sulfites are formed at bronchial mucosa from inhaled sulfur dioxide.
