A Study of Global Quality Scale and Reliability Scores for Chest Pain: An Instagram-Post Analysis.

INTRODUCTION: Utilized in the healthcare sector, social media offers numerous benefits. However, its drawbacks encompass the variable quality of unregulated and unsupervised content. Thus, we aimed to evaluate the information in content related to chest pain found across Instagram and analyze the quality and reliability of chest pain-related content via Instagram posts. METHODOLOGY: Instagram posts with content related to chest pain were analyzed with the help of a structured questionnaire that included the Global Quality Scale (GQS) and DISCERN score (DS). To collect Instagram posts, several distinct hashtags were employed: #chestpain, #chestpains, #angina, #anginatreatment, #heartattack, #heartattacksurvivor, #heartattackprevention. RESULTS: A total of 262 posts were included, of which 29.7% of the total posts (n=78) contained information that describes the etiology of the disease. 27.8% of the total posts (n = 73) enclosed promotional content. Posts were found to be uploaded by doctors (18.7%), hospitals (15.6%), patients (17.9%), dieticians (11.1%), healthcare organizations (9.2%), and others (27.5%). Both Global Quality and DISCERN scores were statistically significant with a p-value of 0.001. CONCLUSIONS: The findings of this study revealed that most of the Instagram content on chest pain posted via physicians were highly reliable and had a better global quality score. Information regarding various causes, symptoms and preventive measures on Instagram can be considered as an acceptable source for patients to surf on. A major limitation is that only English content was analyzed. In the future, the use of higher quality posts produced by healthcare professionals could potentially contribute to enhancing patient education via Instagram.

Inhibitory behavior and adsorption of asparagine dipeptide amino acid on the Fe(111) surface.

CONTEXT: The inhibitory effect of asparagine (Asn) and its derivatives on iron (Fe) corrosion was studied by performing density functional theory (DFT) calculations. In this paper, the global and local reactivity descriptors of Asn in the protonated and neutral forms were evaluated. Also, the changes in reactivity were investigated when dipeptides were combined with Asn. Due to the increase in the reaction centers within their molecular structure, there was an enhancement in the inhibitory effect of these dipeptides. Moreover, the adsorption energies (Eads) and the adsorption configurations of Asn and small peptides (SPs) with most stability were determined on the surface of Fe(111). It was found that dipeptides had a chemical adsorption on these substrates. In the protonated forms, there was an enhancement in the absolute values of Eads between the inhibitors and the Fe(111) surfaces. Peptides were more likely to be adsorbed on the Fe surfaces, showing the great inhibitory effect of these moieties. The results of the current research demonstrate the possibility of utilizing SPs as efficient "green" corrosion inhibitors. METHODS: DFT computations were undertaken by employing the BIOVIA Material Studio with B3LYP-D3 functional and 6-31 + G* basis set. The theoretical evaluation of the inhibitory effect of asparagine (Asn) dipeptides, and the potential analysis of small peptides to protect against the corrosion of Fe, was done.

High efficiency of Ag0 decorated Cu2MoO4 nanoparticles for heterogeneous photocatalytic activation, bactericidal system, and detection of glucose from blood sample.

The novel Ag0/Cu2MoO4 nanoparticles was simply synthesized via chemical method. Ag/Cu2MoO4 nanoparticles was characterized by FESEM image, XRD curve, UV-vis spectroscopy, BET analysis, and XPS spectrum. XRD pattern depicts that the cubic crystalline phase of particles. The band gap of Ag/Cu2MoO4 nanoparticles was achieved to 2.04 eV, which that depicted the best activity under visible light irradiation. Ag/Cu2MoO4 nanoparticles exhibits 99.74% degradation under light and persulfate ion which was higher response than Cu2MoO4 nanoparticles (83.56%) under this condition. The scavenging test indicates the important reactive species in removal process were •OH, and •SO4-. The Ag/Cu2MoO4 nanoparticles was indicated highly photo-stability for the MG degradation after 5th cycle. Ag/Cu2MoO4 exhibits substantial antibacterial properties against P. aeruginosa and S. pneumoniae. Moreover, Ag/Cu2MoO4 nanoparticles was experimented to peroxidase-like performance for the colorimetric detection of glucose with the Limit of Detection about 52.23 nM.
