Representation of Health Conditions on Facebook: Content Analysis and Evaluation of User Engagement

Conclusions: This research represents the first attempts to comprehensively describe publicly available health content and user engagement with health conditions on Facebook pages. Public health interventions using Facebook will need to be designed to ensure relevant information is easy to find and with an understanding that stigma associated with some health conditions may limit the users’ engagement with Facebook pages. This line of research merits further investigation as Facebook and other SNS continue to evolve over the coming years.

This article presents a unique 3D biocompatible Aluminum-based quantum structure (QS) for in vitro cancer detection using Surface Enhanced Raman Scattering (SERS). The Al-based QSs fabricated using ultrashort pulsed laser are of two distinct surface characters, wrinkled and smooth spherical. The limit of detection for chemical sensing of Crystal Violet and Rhodamine 6G by the Al-QS was driven up to single molecule sensing (femtomolar concentration). Biological sensing of cysteine, a disease biomarker and carcinoembryonic antigen (CEA), a cancer biomarker was also tested by the Al-QS. The ability of in vitro cell detection ...

In this study, four different weight% of Punica granatum fruit peel extract were used as green stabilizers to synthesize IONPs followed by a series of characterization experiments and in vitro anticancer evaluation. Results revealed that all synthesized IONPs have high degree of crystallinity and purity. The optimum saturation magnetization, and hydrodynamic size were found to be ∼69 emu.g−1, and 26.52 nm, respectively. Morphological studies demonstrated that adding peel extract decreased size of NPs with the average particle size below 11 nm. Cytotoxicity assay showed that the IONPs were not react...

Villanueva-Toledo, G.J. Mena-RejónAbstractThe structural modification of natural products has shown to be a remarkable tool in the generation of novel bioactive molecules. Herein, the synthesis, structural analysis and anticancer activity of the novel triterpenoid thiazole 3 is reported. The synthesis was carried out through the bromination of ochraceolide A (1) and the subsequent heterocyclic condensat...

GudasAbstractEthanol (EtOH) is a recreationally ingested compound that is both teratogenic and carcinogenic in humans. Because of its abundant consumption worldwide and the vital role of stem cells in the formation of birth defects and cancers, delineating the effects of EtOH on stem cell function is currently an active and urgent pursuit of scientific investigation to explicate some of the mechanisms contributing to EtOH toxicity. Stem cells represent a primordial, undifferentiated phase of devel...

Therefore, monitoring the changing of intracellular polarity can great improve the understanding its functions in living cell level. Herein, by employing p-phenylenediamine as precursor, we prepared a red emissive carbon dots based nanoprobe for real-time sensing polarity in living cells. With the i...

This study demonstrates that the concentrations of PM-bound PAHs are mutagenic and that the Excess Cancer Risks exceed the USEPA standard limits. PMs cause cytotoxicity and can also induce genotoxicity to human health analyzed by cell culture and gel electrophoresis. This study helps to promote research to evaluate the PMs bound PHEs toxicity in diverse human cell lines and also their relationship with climatic factors as well as quantitative source apportionment for mitigation purposes.Graphical abstract

In this study, we verified that ferroptosis occurred in animal models of arsenic-induced pancreatic dysfunction through assessing proferroptotic markers and morphological changes in mitochondria. In vitro, arsenic caused execution of ferroptosis in a dose-dependent manner, which could be significantly reduced by ferrostatin-1. Additionally, arsenic damaged mitochondria manifested as diminishing of mitochondrial membrane potential, reduced cytochrome c level and production of mitochondrial reactive oxygen species (MtROS) in MIN6 cells. Using the Mito-TEMPO, we found the autophagy level and subsequent ferroptotic cell death ...

Conclusions: Treatment with biologics affects the cytokine profile in inflammatory synovial fluid in patients with both AS and RA. Furthermore, IL-23 and IL-17 cytokine might be an important factor in some patients who are unresponsive to biologics in AS. PMID: 31830775 [PubMed - as supplied by publisher]

This study aimed to review the outcomes of percutaneous treatment with a mother-child technique in the treatment of symptomatic central venous stenosis (CVS) and central venous occlusion (CVO) in patients on hemodialysis.MethodsData were collected retrospectively and included all consecutive patients with CVS or CVO who were treated with percutaneous angioplasty and stenting. The occlusive lesions were crossed using the mother-child technique with an angiographic catheter-in-guiding catheter system.ResultsA total of 36 patients with symptomatic CVS and 45 patients with total CVO were included. The average age and gender co...
