Circular RNAs (circRNAs) are a unique class of endogenous RNAs which could be used as potential diagnostic and prognostic biomarkers of many diseases. Our study aimed to investigate circRNA profiles in human granulosa cells (GCs) during maternal aging and to uncover age-related circRNA variations that potentially reflect decreased oocyte competence. CircRNAs in GCs from in vitro fertilization (IVF) patients with young age (YA, ≤ 30 years) and advanced age (AA, ≥ 38 years) were profiled by microarray, and validated in 20 paired samples...

Nucleic acids based adjuvants recognized by Toll-like receptors (TLR) are potent immune system stimulants that can augment the anti-tumor immune responses in an antigen-specific manner. However, their clinical uses as vaccine adjuvants are limited primarily due to lack of accumulation in the lymph nodes, the anatomic sites where the immune responses are initiated. Here, we showed that chemical conjugation of type B CpG DNA, a TLR9 agonist to dextran polymer dramatically enhanced CpG's lymph node accumulation in mice...

Silver(i) chalcogenide/chalcogenolate clusters are promising photofunctional materials for sensing, optoelectronics and solar energy harvesting applications. However, their instability and poor room-temperature luminescent quantum yields have hampered more extensive study. Here, we graft such clusters to adaptable bridging ligands, enabling their interconnection and the formation of rigid metal-organic frameworks. By controlling the spatial separation and orientation of the clusters, they then exhibit enhanced stability (over one year) and quantum yield (12...

Fibrinogen (Fib) is a useful marker for predicting the severity of coronary artery disease (CAD) in adult population. However, whether Fib can be a predictor for the presence and severity of CAD in very young MI patients (≤35 years old) remains to be determined. A total of 418 males from 61,863 patients with MI who were under 35 years old were sequentially recruited in our study. The patients were divided into two main groups and three subgroups according to coronary angiograph and Gensini score (GS) system: no coronary artery stenosis (group A), the results of the coronary artery stenosis (group B); low GS, intermediate GS and high GS...

We report on a 12-year-old adopted boy with psychomotor disability, absence seizures, and normal brain MRI. He showed increased (but initially, at 5 months, normal) serum cholesterol, increased alkaline phosphatases, transiently increased transaminases and hypoceruloplasminemia with normal serum and urinary copper. Blood levels of immunoglobulins, haptoglobin, antithrombin, and factor XI were normal. A type 2 serum transferrin isoelectrofocusing and hypoglycosylation of apoCIII pointed to a combined N- and O-glycosylation defect...

We aimed to evaluate the role of pretreatment carcinoembryonic antigen (CEA) and platelet to lymphocyte ratio (PLR) in predicting brain metastasis after radical surgery for lung adenocarcinoma patients. The records of 103 patients with completely resected lung adenocarcinoma between 2013 and 2014 were reviewed. Clinicopathologic characteristics of these patients were assessed in the Cox proportional hazards regression model. Brain metastasis occurred in 12 patients (11.6%). On univariate analysis, N2 stage (P = 0...

Enterotoxigenic Escherichia coli (ETEC) is a leading cause of diarrhea among children and travelers in developing countries, and heat-labile enterotoxin (LT) is one of the most important virulence factors. The pathogenesis of and virulence factors associated with ETEC have been well-characterized; however, the extent to which ETEC damages host cells remains unclear. In this study, we found that LT could induce decreases in intestinal epithelial cell viability and induce apoptosis in a dose- and time- dependent manner in both HCT-8 and Caco-2 cells...

Efflux transporters have been implicated in regulating bacterial virulence properties such as resistance to antibiotics, biofilm formation and colonization. The pathogenicity of Streptococcus mutans, the primary etiologic agent of human dental caries, relies on the bacterium's ability to form biofilms on tooth surface. However, the studies on efflux transporters in S. mutans are scare and the function of these transporters remained to be clarified. In this study, we identified an efflux transporter (LmrB) in S...

OBJECTIVE: Diabetic subjects are at higher risk of ischemic peripheral vascular disease. We tested the hypothesis that advanced glycation end products (AGEs) and their receptor (RAGE) block neoangiogenesis and blood flow recovery after hindlimb ischemia induced by femoral artery ligation through modulation of immune/inflammatory mechanisms. APPROACH AND RESULTS: Wild-type mice rendered diabetic with streptozotocin and subjected to unilateral femoral artery ligation displayed increased accumulation and expression of AGEs and RAGE in ischemic muscle...

Nowadays many children receive operations with general anesthesia. Isoflurane is a commonly-used general anesthetic. Numbers of studies demonstrated that isoflurane induced neurotoxicity and neurobehavioral deficiency in young rats, however, the underlying mechanism remained unknown. Cell division cycle 42 (cdc42) played an important role in regulating synaptic vesicle trafficking and actin dynamics in neuron, which closely linked to synaptic plasticity and dendritic spine formation. Meanwhile, cdc42 also involved in many neurodegenerative diseases...

BACKGROUND: Pre-emptive pregabalin might be beneficial to the patients undergoing laparoscopic cholecystectomy. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the effect of pregabalin on pain management of patients undergoing laparoscopic cholecystectomy. METHODS: PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of pregabalin versus placebo on laparoscopic cholecystectomy were included...

The Krüppel-like factor (KLF) family, as the SP/XKLF transcription factors, plays important roles in regulating the expression of genes required for the proper execution of important biological and pathological processes. Recent studies have demonstrated that KLF14, a member of the KLF family, participates in the initiation and progression of atherosclerotic cardiovascular disease (CVD). From the molecular function aspect, this review focuses on the impact of KLF14-mediated regulation in major atherosclerosis-related diseases and pathological processes, such as insulin resistance, type 2 diabetes, dyslipidemia, inflammation, obesity, metabolic syndrome, cell proliferation and differentiation...
