Ti-based implants sometimes fail to integrate with surrounding bone tissue due to insufficiency of new bone formation and surface bonding. To overcome this problem, this research focused on establishing a sustained bone growth factor delivery system by applying anodized TiO2 nanotube arrays and PLGA film on the titanium implant surface. TiO2 nanotube arrays were made by anodic oxidation method, and were then filled with rhBMP2 by vacuum freeze-drying. Next, PLGA was deposition on the surface of this material...

BACKGROUND: Henoch-Schönlein purpura nephritis (HSPN) is a form of small vessel vasculitis associated with purpura and IgA deposition in the glomeruli. The International Study of Kidney Disease in Children (ISKDC) classification predicts renal prognosis in children with HSPN, but not in adults. Additionally, it is not well known whether the Oxford classification 2016 and/or the Japanese Histologic classification (JHC) are associated with renal outcome. Herein, we investigated the relationship between pathological characteristics and renal outcome among adult patients with HSPN...

The cation-dependent mannose-6-phosphate receptor (CD-MPR) is a member of the P-type lectin family. As a type I transmembrane glycoprotein, it functions in the delivery of newly synthesized acid hydrolases from the trans-Golgi network to endosomes for their subsequent transfer to the lysosome by binding the mannose-6-phosphate receptor-recognition moieties in the hydrolases. However, the functions of CD-MPR in immune responses are seldom reported. In the present study, we identified a CD-MPR-like molecule in Marsupenaeus japonicus and designed it as MjCD-MPR...

Stimulation of cytosolic nucleic acid sensors of innate immunity by pathogen-derived nucleic acids is important for antimicrobial defence, but stimulation through self-derived nucleic acids may contribute to autoinflammation and cancer. DNA sensing in the cytosol requires the stimulator of interferon genes (STING), while cytosolic RNA sensors use mitochondrial antiviral-signalling protein (MAVS). In a murine model of two-thirds hepatectomy, combined deficiency of MAVS and STING resulted in strongly impaired hepatocyte proliferation and delayed recovery of liver mass...

The photoluminescence (PL) properties of silicon-on-insulator (SOI) samples, modified by the Si+ self-ion-implantation (SII) into Si thin film followed by annealing, have been well investigated. The well-known W-line can also be observed in SII SOI samples, its emitting behavior and structural evolution have been discussed in this article. The parallel PL pattern trend and the similar changes of temperature-dependent intensity suggest that luminescence center of I1 and I2 peaks located in the near-infrared band originates from the same interstitial-clusters (In Cs)...

Microstructure of hydroxyapatite is known to influence cellular behavior, can be performed as a substrate for osteoblast growth, and exploited as a drug release platform. However, easy delamination and self-decomposition of hydroxyapatite caused by poor adhesion with substrates are the main problems currently. In this paper, we successfully fabricated TiO2/SrHA composite scaffolds by self-generated strontium substituted hydroxyapatite microspheres in TiO2 nanotubes. Moreover, the active compound 1-(5-bromo-2-hydroxy-methoxyphenyl)-ethanone (BHM) from Seahorse (Hippocampus kuda Bleeler) was loaded in this scaffold, and the controlled release kinetics of BHM was studied...

Glucocorticoids (GCs) are widely used to treat chronic diseases. Prolonged and/or overdose administration of GCs has many side-effects to human health including GC-induced osteoporosis (GIOP). In this investigation, the objective was to assess the influence that echinacoside (ECH) exerts upon dexamethasone-treated murine osteoblastic MC3T3-E1 cells. We found that ECH (5, 10, 20 and 40 mg/l) inhibited dexamethasone (1,000 nM)-suppressed cell viability as demonstrated by Cell Counting Kit-8 (CCK-8) assay. The dose of 10 mg/l was selected for the following experiments because this dose had a better effect than the dose of 5 mg/l, and the doses >10 mg/l had a similar effect as this dose...

Hepatitis C virus (HCV) infection is a major cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. HCV can be sensed by host innate immunity to induce expression of interferons (IFNs) and a number of antiviral effectors. In this study, we found HCV infection induced the expression of Neuralized E3 Ubiquitin Protein Ligase 3 (NEURL3), a putative E3 ligase, in a manner that requires the involvement of innate immune sensing but is independent of the IFN action. Furthermore, we showed that NEURL3 inhibited HCV infection, while had little effect on other RNA viruses including zika virus, dengue virus and vesicular stomatitis virus...

Coordination polymers (CPs) supporting tunable through-framework conduction and responsive properties are of significant interest for enabling a new generation of active devices. However, such architectures are rare. We report a redox-active CP comprised of two-dimensional (2D) lattices of coordinatively bonded Mo2 (INA)4 clusters (INA=isonicotinate). The 2D lattices are commensurately stacked and their ordering topology can be synthetically tuned. The material has a hierarchical pore structure (pore sizes distributed between 7-33 Å) and exhibits unique CO2 adsorption (nominally Type VI) for an isotherm collected at 195 K...

The next generation of micro/nano-fluidic systems, featuring manipulation of a single nanoliter volume of a chemical reactant or bio-substance, is greatly dependent on the accurate manipulation of a single nano-droplet. In this paper, to resolve the lack of efficient methods for 3-D actuation of nano-droplets with high tunability, we proposed an electro-wetting-on-dielectric (EWOD) driving scheme on a graphene surface. The droplet could be actuated when the EWOD-saturated contact angle was reached, which determined the critical magnitude of the E-field...

Hepatocellular carcinoma (HCC) is one of the most prevalent malignancies worldwide. Histone‑lysine N‑methyltransferase SET7/9 is a protein lysine monomethylase that methylates histone H3K4 as well as various non‑histone proteins. Deregulation of SET7/9 is frequently detected in human cancers. However, the role of SET7/9 in HCC development remains unclear. In the present study, upregulation of SET7/9 and E2F transcription factor 1 (E2F1) expression was detected in 68 samples of HCC tissues compared with these levels noted in the paired healthy liver samples...

BACKGROUND: Contrast-induced nephropathy (CIN) is the third most common cause of acute kidney injury in hospitalized patients. There have been many conflicting results across trials that have evaluated the prophylactic efficacy of prostaglandin E1 (PGE1) for prevention of CIN in patients undergoing percutaneous coronary procedures. PGE1 may have renal-protective effects due to its pleiotropic properties. The aim of this study was to evaluate the efficacy of PGE1 in preventing CIN. MATERIALS AND METHODS: We searched PubMed, Embase, Cochrane Library, Chinese Biomedical Literature, China National Knowledge Infrastructure, VIP Information/Chinese Scientific Journals, and WANFANG databases for randomized controlled trials (RCTs) comparing the preventive effects of PGE1 versus controls (conventional hydration, no PGE1, or placebo) on CIN in patients undergoing percutaneous coronary procedures from January 1999 to June 2016...

Platelet‑derived growth factor‑BB (PDGF‑BB) serves a critical function in human osteoblast differentiation and proliferation. Src and Janus kinase 2 (JAK2) are involved in these processes. In our previous study, it was identified that Src could promote the phosphorylation of JAK2. However, it has yet to be determined whether the Src/JAK2 signaling pathway affects PDGF‑BB‑mediated osteoblast differentiation and proliferation. In the present study, western blotting, polymerase chain reaction, alizarin red staining, alkaline phosphatase and Cell Counting kit‑8 were employed to explore these questions...

We compared the prevention of erosive and erosive/abrasive enamel loss by a medical minerals gel system (R.O.C.S.) to that by an anti-erosive toothpaste. Seventy-two bovine enamel samples were randomly allocated to six groups (E1–E3 and EA1–EA3; n=12). Per day, samples were eroded (2 min) 9 times using HCl (pH 2.6). Between erosive challenges and over night samples were stored in artificial saliva. Per day, samples were stored (100 s; groups E1–E3) or additionally brushed (20 brushing strokes; groups EA1–EA3) in/with slurries prepared from artificial saliva plus: no additional toothpaste (control groups E1 and EA1), elmex erosion protection toothpaste (groups E2 and EA2), or R...

Ubiquitin-proteasome system (UPS) is a primary signaling pathway for regulation of protein turnover and removal of misfolded proteins in eukaryotic cells. Enzymes of the UPS pathway - E1 activating, E2 conjugating, E3 ligating - act together to covalently tag substrate proteins with a chain of ubiquitins, small regulatory proteins. The poly-ubiquitin chain then serves as a recognition motif for 26S proteasome to recognize and degrade the substrate. In recent years UPS has emerged as attractive enzymatic cascade for development of novel therapeutics against various human diseases...
