The Critique of the Anthropological Dimensions of Prayer from Vincent Brommer's Perspective

This research seeks to explain the most important anthropological dimensions of prayer according to Vincent Brommer through analytical and citation methods. The independent man is one of the main components of prayer according to Brommer. Although he has not distinguished the anthropological topics of prayer from other topics, according to his presuppositions and epistemological foundations, it can be said that; Faith, love, human maximum authority, freedom and individuality are the most important anthropological dimensions of prayer for Brommer. In explaining these anthropological issues, he has opened prayer influenced by existentialism and theology. According to Brommer, faith is a necessary and prerequisite for prayer and the essence of man's relationship with God. With a moderate approach to the issue of faith, he considers all three elements of knowledge, action and love to be effective in the truth of faith. In his view, the goal of faith and prayer is love of God. In the light of his belief in man's maximum free will and individuality, Brommer interprets prayer as man's interpersonal relationship with God

MicroRNAs-mediated regulation of the differentiation of dental pulp-derived mesenchymal stem cells: a systematic review and bioinformatic analysis

Background: Human dental pulp-derived mesenchymal stem cells (hDP-MSCs), which include human dental pulp stem cells (hDPSCs) and stem cells from human exfoliated deciduous teeth (SHEDs), are promising cell sources for regenerative therapies. Nevertheless, a lack of knowledge relating to the mechanisms regulating their differentiation has limited their clinical application. microRNAs (miRNAs) are important regulatory molecules in cellular processes including cell differentiation. This systematic review aims to provide a panel of miRNAs that regulate the differentiation of hDP-MSCs including hDPSCs and SHEDs. Additionally, bioinformatic analyses were conducted to discover target genes, signaling pathways and gene ontologies associated with the identified miRNAs. Methods: A literature search was performed in MEDLINE (via PubMed), Web of Science, Scopus, Embase and Cochrane Library. Experimental studies assessing the promotive/suppressive effect of miRNAs on the differentiation of hDP-MSCs and studies evaluating changes to the expression of miRNAs during the differentiation of hDP-MSCs were included. miRNAs involved in odontogenic/osteogenic differentiation were then included in a bioinformatic analysis. A miRNA-mRNA network was constructed, and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed. A protein–protein interaction (PPI) network was also constructed. Results: Of 766 initially identified records through database searching, 42 and 36 studies were included in qualitative synthesis and bioinformatic analyses, respectively. Thirteen miRNAs promoted and 17 suppressed odontogenic/osteogenic differentiation of hDP-MSCs. hsa-miR-140-5p, hsa-miR-218 and hsa-miR-143 were more frequently reported suppressing the odontogenic/osteogenic differentiation of hDP-MSCs. hsa-miR-221 and hsa-miR-124 promoted and hsa-miR-140-5p inhibited neuronal differentiation, hsa-miR-26a-5p promoted and hsa-miR-424 suppressed angiogenic differentiation, and hsa-miR-135 and hsa-miR-143 inhibited differentiation within myogenic lineages. A miRNA-mRNA network including 1890 nodes and 2171 edges was constructed. KEGG pathway analysis revealed MAPK, PI3K-Akt and FoxO as key signaling pathways involved in the odontogenic/osteogenic differentiation of hDP-MSCs. Conclusions: The findings of this systematic review support the potential application of the specific miRNAs to regulate the directed differentiation of hDP-MSCs in the field of regenerative therapies

Antibiotic resistance of Neisseria species in Iran: A systematic review and meta-analysis

Objective: To estimate the prevalence of antibiotic resistance of Neisseria species in Iran. Methods: A systematic and electronic search using relevant keywords in major national and international databases was performed until 6th July, 2018 in order to find studies reporting the prevalence of antibiotic resistance of Neisseria species in Iran. Results: A total of nine studies were found to be eligible based on predefined inclusion and exclusion criteria. Our analysis indicated that the prevalence of Neisseria gonorrhoeae resistance to different antibiotics was as follows: 66.9% to penicillin, 59.1% to ciprofloxacin, 11.1% to ceftriaxone, 21.6% to spectinomycin, 13.8% to cefixime, 82.4% to co-trimoxazole, 52.7% to tetracycline, 29.9% to gentamicin, 87.5% to ampicillin, 11.1% to azithromycin, 2.2% to chloramphenicol, 50.1% to cefepime and 50.0% to vancomycin. Antimicrobial resistance rates of Neisseria meningitidis was as follows: 30.0% to penicillin, 33.3% to amoxicillin, 33.3% to cephalexin, 55.6% to ampicillin and 0.0% to ciprofloxacin, ceftriaxone, cefotaxime, amikacin, co-trimoxazole, gentamicin, kanamycin, chloramphenicol and ceftizoxime. Conclusion: Neisseria gonorrhoeae and Neisseria meningitidis isolates of Iran show resistance to different types of antibiotics. Therefore, care should be exercised for the use of penicillin, ciprofloxacin, co-trimoxazole, tetracycline, gentamicin, ampicillin, cefepime and vancomycin for gonococcal infections, and also with respect to the use of penicillin, amoxicillin, ampicillin and cephalexin for meningococcal infections in Iran

Is Penicillin-Nonsusceptible Streptococcus pneumoniae a Significant Challenge to Healthcare System? A Systematic Review and Meta-Analysis

Background. In recent years, antibiotic-resistant pathogens including penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) have posed serious threats against human health. The aim of this meta-analysis was to investigate the prevalence of Streptococcus pneumoniae drug resistance particularly the incidence of PNSP strains in Iran. Methods. A systematic search was done in national and international electronic databases using Persian and English keywords. Up until May 20, 2020, a total of 58 publications were detected as eligible articles based on the inclusion and exclusion criteria, and then the selected studies were enrolled for data extraction and meta-analysis according to the PRISMA guidelines. Results. A high rate of PNSP (46.9%) and multidrug-resistant (MDR) S. pneumoniae (45.3%) in our isolates were evident. Furthermore, total frequency resistance to other drugs in S. pneumoniae was as follows: erythromycin 41.1%, azithromycin 53.2%, tetracycline 39.9%, levofloxacin 1.7%, rifampin 1.2%, clindamycin 31.7%, vancomycin 1.7%, trimethoprim/sulfamethoxazole 63.9%, chloramphenicol 20%, ceftriaxone 10.9%, amoxicillin 30.5%, ciprofloxacin 8.3%, imipenem 6.1%, linezolid 0%, and cefotaxime 8.3%. Conclusion. Although the overall prevalence of cephalosporin- and carbapenem-resistant Streptococcus pneumoniae was low, penicillin-resistant strains, especially PNSP, could become a significant challenge to the healthcare system in Iran. Hence, the prescription of penicillin as the first-choice antibiotic in the treatment of S. pneumoniae infections should be avoided

Prevalence of Fluoroquinolone-Resistant Campylobacter Species in Iran: A Systematic Review and Meta-Analysis

Background. Campylobacter species are one of the main causes of bacterial food poisoning worldwide. Recently, WHO reported that the emergence of fluoroquinolone-resistant Campylobacter species is becoming a public health issue around the world. The aim of the present systematic review and meta-analysis was to evaluate the prevalence of the antimicrobial susceptibility patterns of Campylobacter species, especially fluoroquinolone-resistant strains isolated from human and animal origins in Iran. Methods. Using related keywords and without date and language limitations, a comprehensive literature search was conducted in PubMed, Scopus, ISI Web of Knowledge, Google Scholar, and SID to identify relevant studies on the prevalence of the antimicrobial susceptibility patterns of Campylobacter species in Iran. Results. A total of 34 reports (9 in Persian and 25 in English) were selected based on inclusion and exclusion criteria. Disk diffusion, E-test, and agar dilution were common methods used for antimicrobial susceptibility testing. The antibiotic resistance profiles of Campylobacter species against fluoroquinolones were as follows: 53.6%, 41.8%, and 0% to ciprofloxacin for C. jejuni, C. coli, and C. lari, respectively, 24.3% and 25.1% to enrofloxacin for C. jejuni and C. coli, respectively, 59.6% and 49.2% to nalidixic acid for C. jejuni and C. coli, respectively, and 87.3% and 64.7% to ofloxacin for C. jejuni and C. coli, respectively. Conclusion. Our findings revealed a high prevalence of fluoroquinolone-resistant Campylobacter species in Iran. This calls for the use of more effective antibiotics with low resistance rates including aminoglycosides, chloramphenicol, and imipenem

Imipenem resistance associated with amino acid alterations of the OprD porin in Pseudomonas aeruginosa clinical isolates

Globally, the spread of carbapenem-resistant strains has limited treatment options for multidrug-resistant (MDR) Pseudomonas aeruginosa infections. This study aimed to determine the role of point mutations as well as the expression level of the oprD gene in the emergence of imipenem-resistant P. aeruginosa strains isolated from patients referred to Ardabil hospitals. A total of 48 imipenem-resistant clinical isolates of P. aeruginosa collected between June 2019 and January 2022 were used in this study. Detection of the oprD gene and its amino acid alterations was performed using the poly-merase chain reaction (PCR) and DNA sequencing techniques. The expression level of the oprD gene in imipenem-resistant strains was determined using the real-time quantitative reverse transcription PCR (RT-PCR) method. All imipenem-resistant P. aeruginosa strains were positive for the oprD gene based on the PCR results, and also five selected isolates indicated one or more amino acid alterations. Detected amino acid alterations in the OprD porin were Ala210Ile, Gln202Glu, Ala189Val, Ala186Pro, Leu170Phe, Leu127Val, Thr115Lys, and Ser103Thr. Based on the RT-PCR results, the oprD gene was downregulated in 79.1% of imipenem-resistant P. aeruginosa strains. However, 20.9% of strains showed overexpression of the oprD gene. Probably, resistance to imipenem in these strains is associated with the presence of carbapenemases, AmpC cephalosporinase, or efflux pumps. Owing to the high prevalence of imipenem-resistant P. aeruginosa strains due to various resistance mechanisms in Ardabil hospitals, the implementation of surveillance programs to reduce the spread of these resistant microorganisms along with rational selection and prescription of antibiotics is recommended

Synthesis, characterization, and CO2 adsorption properties of pure ETS-10

Synthesis of titanosilicate ETS-10 with high purity and crystallinity is a big challenge due to its limited crystallization region. ETS-10 was synthesized and characterized by SEM, EDX, BET, and TGA/DTA methods. The effect of synthesis parameters including pH of the gel, crystallization temperature and time, and the potassium source, were studied using the one-at-a-time (OFAT) approach. The results showed that the ETS-10 with the highest purity was achieved considering the gel pH of 11.3, and the crystallization time and temperature of 72 h and 230 °C. It was also revealed that there was considerable interaction between the potassium source with other synthesis parameters. Afterward, CO2 adsorption of the pure synthesized sample was obtained at 298 K using a volumetric setup. The Dual-site Langmuir, Toth, and UNILAN isotherms were applied to model the obtained equilibrium adsorption data. The CO2 adsorption capacity of the synthesized pure ETS-10 was obtained equal to 3.37 mmol/g. Finally, the adsorption kinetics data were modeled using the PNO model with n = 3.5. The results showed that about 90% of the equilibrium absorption was achieved in only 25 s, which indicates the remarkable capability of using pure ETS-10 for CO2 capture by the PSA method

Effect of crocin, a carotenoid from saffron, on plasma cholesteryl ester transfer protein and lipid profile in subjects with metabolic syndrome: A double blind randomized clinical trial

BACKGROUND: Metabolic&nbsp;syndrome is defined by insulin resistance and a clustering of other cardiovascular risk factors. Crocin is a carotenoid derived from the stigmas of the saffron flower and had previously been shown to affect lipid profile. However, the mechanism for this function is not well understood. The present trial aimed to investigate the possible effect of crocin on plasma levels of cholesteryl ester transfer protein and lipid profile in individuals with metabolic syndrome. METHODS: This was a randomized, double-blind, placebo-controlled, clinical trial consisting of an 8-week treatment with crocin, or placebo tablets between April and June 2014, in the Nutrition Clinic of Ghaem Teaching Hospital, Mashhad, Iran. Participants were randomly assigned to take a 30 mg/day crocin (n = 22) in the intervention group or placebo (n = 22) in the control group. Anthropometric, hematological and biochemical parameters were measured and recorded during pre and post-treatment periods. RESULTS: Whilst plasma cholesteryl ester transfer protein was&nbsp;increased in the group taking the crocin tablet by 27.81% during the trial period (P = 0.013), the difference between the crocin and placebo groups was not significant (P = 0.116). Moreover, the percent changes in cholesterol (P = 0.702), triglyceride (P = 0.080), low-density lipoprotein (LDL) (P = 0.986), high-density lipoprotein (HDL) (P = 0.687) and fasting blood glucose (P = 0.614) did not differ significantly between intervention and control groups. CONCLUSION: Although crocin supplements increased the serum cholesteryl ester transfer protein in patients with metabolic syndrome, this change was not significant between treatment and placebo groups. &nbsp;</p
