This study proposes a memory-based search strategy for the fruit fly optimization algorithm (FOA) to enrich its search ability, and utilizes an improved Deb (IDeb) rule to tackle the constraints and increase the computational efficiency of the FOAs. Unlike other FOAs that employ a predefined search radius, the proposed search strategy mines the knowledge of both the swarm and the individuals to adaptively determine the vision search radius of each fruit fly. The improved Deb...

Salidroside is an active ingredient extracted from Rhodiola rosea that has anti-tumor activities. The current paper attempted to assess the impact of Salidroside on gastric cancer (GC) and explore the potential mechanism. GC cell lines (SNU-216 and MGC803) and gastric epithelial cell line GES-1 were treated with Salidroside. CCK-8 assay, colony formation assay, flow cytometry and Transwell assay were respectively performed to evaluate GC cells phenotype. qRT-PCR and western blot were conducted to reveal the...

Peripheral nerve injury has troubled clinical doctors for many years. To obtain better function recovery of peripheral nerve repair at the base of hollow nerve guidance conduit (NGC), many NGCs with fillers were developed in the application of tissue-engineered nerve graft. In this study, expanded 3D nanofibre sponge scaffolds with orientation and porosity were first fabricated by electrospinning and gas-foaming technique. Polylactic acid (PLA)/silk fibroin nanofibre sponge scaffolds were prepared as filler to construct 3D...

Although cell-penetrating peptides (CPPs) has been proven to be efficient transporter for drug delivery, ideal peptide vectors for tumor therapy are still being urgently sought. Peptide antagonists have attracted substantial attention as targeting molecules because of their high tumor accumulation and antitumor activity compared with agonists. SPA, a derivative of substance P, is a potent antagonist that exhibits antitumor activity. Based on the amino acid composition of SPA, we speculate that it can translocate across...

Several lines of evidence suggest that circular RNAs (circRNAs) play important roles in oncogenesis and tumor progression. However, our knowledge of the role of circRNAs in gastric cancer (GC) remains limited. We investigated the possibility that circular RNA 0047905 (circRNA0047905) might act as a tumor promoter in the pathogenesis of gastric cancer by profiling miRNA expression in GC tissues and paired noncancerous mucosa tissues using miRNA microarrays. Next, a ceRNA network was constructed according to...

Spermatogenesis is an important physiological process associated with male infertility. As a kind of post-transcriptional regulation, RNA editings (REs) change the genetic information at the mRNA level. But whether there are REs and what’s the role of REs during the process are still unclear. In this study, we integrated published RNA-Seq datasets and established a landscape of RNA REs during the development of mouse spermatogenesis. Totally, 7530 editing sites occurred in 2012 genes among all...

Background: As a noninvasive respiratory support mode, high-flow nasal cannula (HFNC) is widely used in preterm infants at neonatal care units. HFNC is often used as an alternative to nasal continuous positive airway pressure (NCPAP) for initial or post-extubation respiratory support. The purpose of this meta-analysis is to evaluate and compare the efficacy and safety of HFNC and NCPAP for respiratory support in preterm infants. Methods: We searched PubMed, Web of Science, Embase, Cochrane Library,...

In this study, sevoflurane (SF) loaded, Fas ligand conjugated reduced graphene oxide (rGO) system is fabricated as a therapeutic agent to target brain ischaemic region. The fluorescence investigation of mice brain denoted that the encapsulated SF in rGOs adsorbed with Fas ligand antibody could be significantly distributed to the ipsilateral side of the ischaemic brain. In addition, the immune-histochemical assay presented that the specific nanoparticles especially deposited in the ischaemic part of the tested mice...

The anti-inflammatory function of microRNA-124 (miR-124) has been a matter of extensive studies in the last few years. Although LINC00305 regulates biological activities by acting as a miR sponge, it is still unexplored whether LINC00305 is involved in inflammation by regulating miR-124. Cell viability and apoptosis were evaluated with commercial kits, cell counting kit-8 (CCK-8) and Annexin V-fluorescein isothiocyanate (FITC) kit, respectively. LINC00305, miR-124 and mRNA levels were quantified by quantitative reverse transcription PCR (qRT-PCR)....

To better evaluate HIV-1 vaccines and therapeutics, the National Institutes for Food and Drug Control of China developed a panel of HIV-1 pseudoviruses including 462 viral strains derived from China, covering the majority of contemporaneous subtypes and circulating recombinant forms. Compared with the standard pseudovirus panels derived from other countries/regions, the Chinese isolates are more susceptible to neutralization by the sera obtained in China, revealing the strain/subtype specificity. Some of these pseudoviruses have already been...

Recently, we showed that parathyroid hormone-like hormone (PTHLH), a cytokine-like polyprotein, is critical for extracellular matrix (ECM) deposition through the activation of hepatic stellate cells (HSCs). Here, we show that N-terminal PTHLH is secreted into the supernatant of injured hepatocytes, its expression is positively correlated with liver fibrosis severity based on mice liver biopsies, and it is primarily expressed in the cytoplasm of hepatocytes along the fibrous septa of fibrotic livers. PTHLH overexpression in mice...
