Path analysis to identify factors influencing health skills and behaviors in adolescents: a cross-sectional survey.
PLoS ONE
PUBLISHED: 08-08-2014
Show Abstract
Hide Abstract
Studies conducted in the past mostly rely on models of functional health literacy in adult populations. However, such models do not satisfy the need for health intervention in adolescents. The identification of key factors influencing adolescents' health literacy is essential in developing effective prevention and intervention measures. This study aimed to test a theoretical model of predictors on health skills and health behaviors in adolescents.

Hide Abstract
Smoke-free legislation was implemented in Guangzhou on 1 September 2010. However, the smoke-free policy did not cover all indoor areas and smoking rooms can be set in some public places. This study aimed to assess changes in self-reported second-hand smoke (SHS) exposure in different types of venues and in homes, in order to evaluate the effectiveness of smoke-free legislation.

Variants in the 5'-upstream region of GPC5 confer risk of lung cancer in never smokers.
Cancer Epidemiol
PUBLISHED: 01-20-2014
Show Abstract
Hide Abstract
A recent genome-wide study (GWAS) has identified GPC5 as a promising susceptibility gene for Lung cancer in never smokers (LCINS). However, the most significant single nucleotide polymorphism (SNP) in this GWAS, rs2352028, has yielded controversial results. The aim of this study was to clarify the relationship between rs2352028 and LCINS. Considering that rs2352028 might be largely marker-SNP correlated to causative variants, two predicted functional SNPs, rs3759452 and rs7322083, were additionally investigated in this study.

Hide Abstract
The role of aspirin use in chemoprevention of esophageal adenocarcinoma (EAC) is still unclear. Previous meta-analyses have reported a beneficial effect of aspirin use, whereas it remains still under debate whether there are non-linear frequency-risk and duration-risk relations, such as a "threshold" effect.

XRCC1 Arg399Gln polymorphism confers risk of breast cancer in American population: a meta-analysis of 10846 cases and 11723 controls.
PLoS ONE
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
In the X-ray repair cross-complementing group 1 (XRCC1) gene, a polymorphism, Arg399Gln (rs25487), has been shown to change neoconservative amino acid and thus result in alternation of DNA repair capacity. Numerous studies have investigated the association between Arg399Gln and breast cancer risk in the American population, but yielding inconsistent results. This study aimed to clarify the role of this polymorphism in susceptibility to breast cancer.

The efficacy and safety of linezolid and glycopeptides in the treatment of Staphylococcus aureus infections.
PLoS ONE
PUBLISHED: 02-01-2013
Show Abstract
Hide Abstract
To assess the effectiveness and safety of linezolid in comparison with glycopeptides (vancomycin and teicoplanin) for the treatment of Staphylococcus aureus infections, we conducted a meta-analysis of relevant randomized controlled trials. A thorough search of Pubmed and other databases was performed. Thirteen trials on 3863 clinically assessed patients were included. Linezolid was slightly more effective than glycopeptides in the intent-to-treat population (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.01-1.10), was more effective in clinically assessed patients (OR 95% CI: 1.38, 1.17-1.64) and in all microbiologically assessed patients (OR 95% CI: 1.38, 1.15-1.65). Linezolid was associated with better treatment in skin and soft-tissue infections (SSTIs) patients (OR 95% CI: 1.61, 1.22-2.12), but not in bacteraemia (OR 95% CI: 1.24, 0.78-1.97) or pneumonia (OR 95% CI: 1.25, 0.97-1.60) patients. No difference of mortality between linezolid and glycopeptides was seen in the pooled trials (OR 95% CI: 0.98, 0.83-1.15). While linezolid was associated with more haematological (OR 95% CI: 2.23, 1.07-4.65) and gastrointestinal events (OR 95% CI: 2.34, 1.53-3.59), a significantly fewer events of skin adverse effects (OR 95% CI: 0.27, 0.16-0.46) and nephrotoxicity (OR 95% CI: 0.45, 0.28-0.72) were recorded in linezolid. Based on the analysis of the pooled data of randomized control trials, linezolid should be a better choice for treatment of patients with S. aureus infections, especially in SSTIs patients than glycopeptides. However, when physicians choose to use linezolid, risk of haematological and gastrointestinal events should be taken into account according to the characteristics of the specific patient populations.

Microwave-assisted synthesis of arene ruthenium(II) complexes that induce S-phase arrest in cancer cells by DNA damage-mediated p53 phosphorylation.

Hide Abstract
A series of arene ruthenium(II) complexes coordinated by phenanthroimidazole derivates, [(C6H6)Ru(L)Cl]Cl·2H2O (1b L = IP, 2b L = p-NMe2PIP, 3b L = p-MeOPIP, 4b L = p-HOPIP, 5b L = p-COOHPIP, 6b L = p-CF3PIP, 7b L = p-BrPIP) have been synthesized in yields of 89-92% under microwave irradiation in 30 min, and the crystal structure of 1b by XRD gives a typical "piano stool" conformation. The antitumor activity of these complexes against various tumor cells have been evaluated by MTT assay, and the results show that this type of arene Ru(II) complexes exhibit acceptable inhibitory effect against all of these tumor cells, especially osteosarcoma MG-63 cells, but with low toxicity toward HK-2 human normal cells. Studies on the mechanism revealed that cell cycle arrest at S-phase in MG-63 cells induced by the arene Ru(II) complex 2b, which was confirmed by the increase in the percentage of cells at S-phase and down-regulator of cyclin A. The further studies by Comet assay at single cell level indicated that DNA damage in MG-63 cells was triggered by 2b, following with the up-regulation of phosphorylated p53 and histone. The studies by spectroscopy in vitro also indicate that 2b bind to DNA molecule by intercalative mode to disturb the bio-function of tumor cells. In conclusion, the synthetic arene Ru(II) complexes could serve as novel p53 activator with potential application in cancer chemotherapy.

Construction and characterization of an anti-asialoglycoprotein receptor single-chain variable-fragment-targeted melittin.

PUBLISHED: 03-20-2011
Show Abstract
Hide Abstract
Antibody-therapeutic agent conjugation to be delivered specifically to tumor cells is required for many target-based therapeutic strategies. In the present study, a recombinant immunotoxin was constructed by which melittin was fused to an anti-asialoglycoprotein receptor (ASGPR) single-chain variable fragment antibody (C1), and targeting ability and cytolytic efficacy of the fusion protein were studied. Our results suggested that the recombinant 29.4 kDa protein C1M was expressed in Escherichia coli as a soluble style. Binding of C1M to the surface of hepatocellular carcinoma (HCC) cells was confirmed by both immunohistochemistry and flow cytometry assays. C1M kept the hemolytic activity of melittin and exhibited cytolytic capacity to HepG2 cells at a concentration of 1.5 µg/mL, under which erythrocytes would not be lysed. The effects were greatly inhibited by coadministration with asialoorosomucoid, a natural ligand for ASGPR. These results suggested that C1M conferred targeting and ASGPR-specific cytotoxicity to HCC cells. This work makes it possible to further investigate its antihepatoma efficacy in vivo.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
