Background: This study aimed to observe the changes in the ocular surface after phacoemulsification in patients with age-related cataracts with respect to the addition of varying concentrations of hyaluronate.
Methods: Patients with dry eye syndrome were treated with 0.3% and 0.
Objective: The aim of this study is to analyze the effect of the artificial tear drop administration time on the regularity of the corneal surface in patients with dry eye.
Methods: Patients with cataract who were admitted to the hospital from January 2018 to December 2018 were divided into four groups (A, B, C, and D) based on their grade of noninvasive tear break-up time (NIBUT) and the concentration of the eye drops used. Groups A and C were classified as NIBUT grade 1 (NIBUTf of 6-9 s and NIBUTav of 8-13 s), and groups B and D were classified as NIBUT grade 2 (NIBUTf of <5 s and NIBUTav of ≤7 s).
Background: Smoking is a leading cause of preventable death. Early studies based on samples of twins have linked the lifetime smoking practices to genetic predisposition. The flavin-containing monooxygenase (FMO) protein family consists of a group of enzymes that metabolize drugs and xenobiotics.

Background The study was designed to access the feasibility, safety, and efficacy of fully covered self-expandable metal stents in the treatment of bronchial fistula. Methods Clinical data of nine patients (seven males and two females) who were treated with placement of tracheobronchial or bronchial fully covered self-expandable metal stents from August 2005 to November 2011 were analyzed retrospectively. Among these patients, seven were diagnosed with bronchopleural fistula, one with tracheopleural fistula, and one with left main bronchoesophageal fistula.

However, traditional analysis methods have difficulties in detecting association signals for rare causal variants because of a lack of statistical power. We propose a two-stage, gene-based method for association mapping of rare variants by applying four different noncollapsing algorithms.

Currently, the genetic and morphological basis of clubfoot is poorly understood. To identify genetic risk factors associated with clubfoot, we performed a genome-wide association study of common genetic variants.

Objective: To detect the pathogenic mutation in a Chinese family with Norrie disease.
Methods: Clinical diagnosis was based on familial history, clinical sign and B ultrasonic examination. Peripheral blood samples were obtained from all available members in a Chinese family with Norrie disease.

Background: Excessive alcohol use is the third leading cause of preventable death and is highly correlated with alcohol dependence, a heritable phenotype. Many genetic factors for alcohol dependence have been found, but many remain unknown. In search of additional genetic factors, we examined the association between Diagnostic and StatisticalManual of Mental Disorders, Fourth Edition (DSM-IV) alcohol dependence and all common copy number variations (CNVs) with good reliability in the Study of Addiction: Genetics and Environment (SAGE).

We examined marker information content and haplotype diversity across 13 recruitment sites (from Europe, United States, and Asia) separately, and conducted principal components analysis (PCA) on parents. As expected, PCA revealed large genetic distances between Europeans and Asians, and a north-south cline from Korea to Singapore in Asia, with Filipino parents forming a somewhat distinct Southeast Asian cluster.

The objective of this research was to identify potential biological pathways associated with non-syndromic cleft lip with or without cleft palate (NSCL/P), and to explore the potential biological mechanisms underlying these associated pathways on risk of NSCL/P. This project was based on the dataset of a previously published genome-wide association (GWA) study on NSCL/P (Beaty et al. 2010).
View Article and Find Full Text PDFNonsyndromic cleft palate (CP) is a common birth defect with a complex and heterogeneous etiology involving both genetic and environmental risk factors. We conducted a genome-wide association study (GWAS) using 550 case-parent trios, ascertained through a CP case collected in an international consortium. Family-based association tests of single nucleotide polymorphisms (SNP) and three common maternal exposures (maternal smoking, alcohol consumption, and multivitamin supplementation) were used in a combined 2 df test for gene (G) and gene-environment (G × E) interaction simultaneously, plus a separate 1 df test for G × E interaction alone.

To investigate the genetic structure of 8 Chinese ethnic populations, haplotype data of 9 short tandem repeats (STR) loci on non-recombining region of the Y chromosome (NRY) from 1816 individuals of 12 populations was obtained from the Database of Genome Diversity and Variation for Chinese Populations (HGD-Chn), unpublished data from Key Laboratory of Forensic Sciences and the prior literature. No specific Chinese population groups could be identified through the analysis of molecular variance (AMOVA) based on Y-chromosomal STRs from these samples. Pairwising F(ST) and Nei's genetic distance values were calculated and significant heterogeneity among these populations were observed.
