Liu, Ying,Liu, Chuan-Xia,Wu, Zhong-Ting,Ge, Lin,Zhou, Hong-Mei Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.8
The purpose of this study was to construct a protein-protein interaction (PPI) network related to oral squamous cell carcinoma (OSCC). Each protein was ranked and those most associated with OSCC were mined within the network. First, OSCC-related genes were retrieved from the Online Mendelian Inheritance in Man (OMIM) database. Then they were mapped to their protein identifiers and a seed set of proteins was built. The seed proteins were expanded using the nearest neighbor expansion method to construct a PPI network through the Online Predicated Human Interaction Database (OPHID). The network was verified to be statistically significant, the score of each protein was evaluated by algorithm, then the OSCC-related proteins were ranked. 38 OSCC related seed proteins were expanded to 750 protein pairs. A protein-protein interaction nerwork was then constructed and the 30 top-ranked proteins listed. The four highest-scoring seed proteins were SMAD4, CTNNB1, HRAS, NOTCH1, and four non-seed proteins P53, EP300, SMAD3, SRC were mined using the nearest neighbor expansion method. The methods shown here may facilitate the discovery of important OSCC proteins and guide medical researchers in further pertinent studies.

Herein, we report a nanocellulose hydrogel that has a packaging structure for on-demand drug release. Zeolitic imidazolate frameworks-8 (ZIF-8) were grown on the surface of polydopamine (PDA) to producePDA@ZIF-8 nanoparticles. The obtained PDA@ZIF-8 nanoparticles were then incorporated into a networkof cellulose nanofibrils (CNFs) to fabricate a PDA@ZIF-8/CNFs composite hydrogel. The loading ratio of thedrug tetracycline hydrochloride (TH) was 58%. A slight burst release behavior was observed at the beginning,and the composite hydrogel presented a significant pH-dependent release behavior. The drug deliverytime of the PDA@ZIF-8/CNFs composite hydrogel was 3.5 times longer than that of the PDA/CNFscomposite hydrogel. Furthermore, NIR light radiation accelerated the drug delivery rate. The drug releasemechanism was mainly driven by anomalous transport. Importantly, the novel PDA@ZIF-8/CNFs compositehydrogel was found to be biocompatible according to in vitro cytotoxicity test. Because of its uniquemultiple drug release responses, the PDA@ZIF-8/CNFs composite hydrogel may be used in future clinicalapplications as a promising drug delivery carrier.

The extraction and solvent partition of the leaves ofEucalyptus citriodora, and repeated column chromatography for n-BuOH fraction yielded a new flavonoid glycoside, citrioside C (1),along with three known flavonoid glycosides (2-4). The latter wereidentified with kaempferol-3-O-β-D-glucopyranosyl (12)-α-L-rhamnoside(2), kaempferol-3-O-α-L-rhamnoside (3), and quercetin-3-O-α-Lrhamnoside(4). Their chemical structures were identified on thebasis of spectroscopic data analyses including NMR, MS, UV, andIR. All constitutents were isolated for the first time from the leavesof Eucalyptus citriodora. The potential antivirus activity of all theisolated compounds was evaluated. Compound 4 showed potentantiviral activity against respiratory syncytial virus with 50%inhibition concentration (IC50) value of 1.9 μg/mL and selectiveindex value of 9.8.

Liu Yu-Ting,Lu Chun-Wei,Mu Pei-Fan,Shu Ying-Mei,Chen Chi-Wen 한국간호과학회 2022 Asian Nursing Research Vol.16 No.3
Purpose: Nowadays most children with congenital heart disease (CHD) are expected to survive to adulthood. The healthcare focus needs to pay close attention to the important developmental tasks during their growth process. The women with CHD face some challenges in their critically developmental stages during pregnancy, delivery, and even motherhood. The lived experience of being a mother needs to be further concerned. This study aimed to explore the lived experience of first-time mothers with CHD. Methods: Descriptive phenomenological design was adopted. Semi-structured interviews were conducted from April to August 2018 with 11 primiparous women with CHD, who were recruited from the pediatric and adult cardiology outpatient departments at a medical center and who had a child aged between 6 months and 3 years. Giorgi's phenomenological analysis method was employed. Results: Six main themes arose from the analysis: (1) recognizing pregnancy risks, (2) performing selfcare for health, (3) building self-worth from my baby, (4) adapting to postpartum life and adjusting priorities, (5) enjoying being a first-time mother, and (6) the factors contributing to success in high-risk childbirth. Conclusions: The experiences that occurred prior to and after labor that were identified in this study can assist women with CHD to more capably prepare for and understand the process of becoming a mother, including recognition of the importance of a prepregnancy evaluation. The findings of this study can help women with CHD to better understand the path to becoming a mother and prepare themselves for the challenges that lie ahead.

Two InR (insulin receptor) genes have been identified in the Nilaparvata lugens. In this study, we used RNA interference (RNAi) to investigate the role of InR genes in the fecundity of N. lugens. The expression of NLInR1 and NLInR2 genes was simultaneously silenced with mixture of dsInR1 and dsInR2 (dsInRs) injection. Our results showed that larvae RNAi against both NLInR1 and NLInR2 reduced the number of eggs laid by N. lugens and some eggs as well as ovaries were abnormal. In addition, the relative expression of Vg (vitellogenin) and VgR (vitellogenin receptor) was significantly reduced on the 4th and 6th days after insects treated with larvae RNAi reached the adult stage. We also determined the relative expression levels of insulin/insulin-like signaling (IIS) related genes in RNAi-treated larvae and found that the expression levels of Chico (homologous receptor substrate), Akt (protein kinase B), PI3K (phosphoinositide 3-kinase), and PTEN (phosphatase and tensin homolog) genes decreased whereas FOXO (forkhead box O) and GSK3 (glycogen synthase kinase-3) levels increased on the 4th and 6th days after insects reached the adult stage. These results indicate that silencing of NLInR1 and NLInR2 reduces the fecundity of N. lugens through the IIS pathway.
Neurotoxicity of acrylonitrile evaluated by manganese enhanced magnetic resonance imaging

Acrylonitrile (ACN), a chemical compound commonly used to manufacture plastics, has been found in drin king water and as a pollutant in the air. Exposure to high levels of ACN leads to brain lesions via oxidative stress-induced injury. To date, there is no non-invasive method of examining brain lesions. We determined if manganese-enhanced magnetic resonance imaging (MEMRI) can be used to detect brain lesions in ACN-treated rats by exploiting the binding properties of manganese to the enzymes manganesesuperoxide dismutase (Mn-SOD) and glutamine synthetase (GS). Rats exposed to low, mid, and high doses of ACN over 7 days were subjected to MEMRI on the eighth day. Contrast enhancement of the brain decreased in ACN-treated rats, along with marked decreases in Mn-SOD and GS activities, particularly in mid- and high-ACN treated rats. Our study indicates that MEMRI may be a potential non-invasive method of detecting ACN-induced oxidative damage.
