Analysis of HLA Profiles in 390 Uveitis Cases: Insights into Clinical Presentations.

Objective: This study aimed to explain the associations between different types of uveitis and human leukocyte antigen (HLA)-B27, HLA-DR4, and HLA-DRw53.

Methods: A retrospective analysis of 390 uveitis cases was conducted among inpatients and outpatients diagnosed at Weifang Eye Hospital from 2013 to 2016. All 390 patients underwent HLA-B27 examination, and an additional 40 patients underwent examination for HLA-DR4 and HLA-DRw53.

KLF3 Transcription Activates WNT1 and Promotes the Growth and Metastasis of Gastric Cancer via Activation of the WNT/β-Catenin Signaling Pathway.

The transcription factor Krüppel-like factor (KLF) 3 is one of the members of the KLF family, which plays an important role in tumor progression. Nevertheless, the role of KLF3 in the growth and metastasis of gastric cancer (GC) still needs to be elucidated. Bioinformatics analysis showed that KLF3 was overexpressed in patients with GC, and the high expression of KLF3 was correlated with poor survival.

The Molecular Mechanism of Long Non-Coding RNA (LncRNA) Regulation of Notch Signaling in Glucose-Induced Apoptosis of Human Retinal Vascular Endothelial Cell.

Diabetes, a global health concern, affects the health of more than 500 million adults. The absence of Notch protein can cause an imbalance in the retinal vascular environment and cause retinal vascular disease. Long noncoding RNA (lncRNA) is known to be involved in the regulation of many signaling pathways.

A meta-analysis of prognostic biomarkers in neonatal retinal hemorrhage.

Purpose: Neonatal retinal hemorrhage (RH) is a frequently occurring neonatal fundus condition and a very common ocular abnormality in neonates. Some of the key factors that influence the rate of RH are the mode of delivery, examination techniques, and time of examination after birth. The prognostic markers of severe RH are poorly known, making it difficult for an efficient diagnosis, prognosis, and treatment.

A review of sample thickness effects on high-resolution transmission electron microscopy imaging.

High-resolution transmission electron microscopy (HRTEM) is an important approach to analyzing material structures. However, in reality, preparing a sufficiently thin sample for use in HRTEM, based on which images could be interpreted by weak phase object approximation theory, is difficult. During the imaging process, the thickness of the sample has two primary effects-a dynamical effect and a non-linear effect.

Leber's Hereditary Optic Neuropathy-Specific Heteroplasmic Mutation m.14495A>G Found in a Chinese Family.

Purpose: Leber's hereditary optic neuropathy (LHON) is a mitochondrial DNA (mtDNA)-associated, maternally inherited eye disease. Mutation heteroplasmy level is one of the leading causes to trigger LHON manifestation. In this study, we aimed to identify the causative mutation in a large Han Chinese family with LHON and explore the underlying pathogenic mechanism in this LHON family.

ABT737 enhances ovarian cancer cells sensitivity to cisplatin through regulation of mitochondrial fission via Sirt3 activation.

Aims: The poor prognosis of ovarian cancer is mainly caused by chemotherapy resistance. Studies show that the Bcl-2 inhibitor ABT737 can significantly improve the effect of cisplatin and induce mitochondrial pathway apoptosis. However, the mechanism of ABT737 increases sensitivity to cisplatin by regulating mitochondrial function remains unclear in ovarian cancer cells.

Applicability of non-linear imaging in high-resolution transmission electron microscopy.

According to transmission cross-coefficient theory, the information limit of non-linear imaging in high-resolution transmission electron microscopy is, under certain conditions, far beyond that of linear imaging, which suggests the possibility of using high-frequency information for structural determination. In this article, we studied the information beyond the linear information limit by means of multislice method simulation, with AlN as an example, and more structural information was obtained by using part of the high-frequency information.

MiR-199a/b-3p suppresses migration and invasion of breast cancer cells by downregulating PAK4/MEK/ERK signaling pathway.

MicroRNA-199a/b-3p is downregulated in several types of aggressive cancer, and its decrement significantly correlates with poor survival. Here, we aim to investigate the biological function of miR-199a/b-3p and its regulation of target genes in breast cancer cells with highly metastatic potential. In addition, we found that miR-199a/b-3p expression was much lower in MDA-MB-231, CAL120, and HCC1395 breast cancer cells with highly metastatic potential.

Identification of a necessary element for Toxoplasma gondii SAG1 gene expression.

SAG1 codes for the stage-specific major surface antigen P30 of Toxoplasma gondii (T. gondii) tachyzoites. Six tandemly repeated, conserved 27 bp cassettes in the region from -231 to -70 bp were previously confirmed to be essential for high-level expression of SAG1 and serve as a positioning element directing the initiation of transcription.
