Virtual Screening and Meta-Analysis Approach Identifies Factors for Inversion Stimulation (Fis) and Other Genes Responsible for Biofilm Production in Pseudomonas aeruginosa: A Corneal Pathogen
No full textBacterial keratitis caused by Pseudomonas aeruginosa is indeed a serious concern due to its potential to cause blindness and its resistance to antibiotics, partly attributed to biofilm formation and cytotoxicity to the cornea. The present study uses a meta-analysis of a transcriptomics dataset to identify important genes and pathways in biofilm formation of P. aeruginosa induced keratitis. By combining data from several studies, meta-analysis can enhance statistical power and robustness, enabling the identification of 83 differentially expressed candidate genes, including fis that could serve as therapeutic targets. The approach of combining meta-analysis with virtual screening and in vitro methods provides a comprehensive strategy for identifying potential target genes and pathways crucial for bacterial biofilm formation and development anti-biofilm medications against P. aeruginosa infections. The study identified 83 candidate genes that exhibited differential expression in the biofilm state, with fis proposed as an ideal target for therapy for P. aeruginosa biofilm formation. These techniques, meta-analysis, virtual screening, and invitro methods were used in combination to diagnostically identify these genes, which play a significant role in biofilms. This finding has highlighted a hallmark target list for P. aeruginosa anti-biofilm potential treatments

Public attitude and justification to purchase antibiotics in the Eastern region Al Ahsa of Saudi Arabia
No full textAbstractUse of non-prescription antibiotics can portend danger and predispose the populace to changes in bacterial resistance pattern. The aims of this study were to (a) evaluate the knowledge and attitudes of residents of Al-Ahsa community, Saudi Arabia on the use of non-prescribed antibiotics. (b) To identify possible predictors (if any) for self-medication within the community.A cross-sectional survey study, using self-administered questionnaire was conducted in two sections; demographics and self-medication attitude (in form of self-antibiotic use). Questions contained the following outcomes; for demographics; gender, age, education level and common disease within the community. Whereas the second part evaluated sources of information, knowledge of antibiotics, frequency/duration of use, underlined illness in which drug use was employed, names of antibiotics used and awareness of adverse effects of antibiotics. Results revealed that the adult population in the 18–40year age range constituted about 82.5% of the respondents. Also 18–29age group made of 60.5% of the respondents and that 56.8% the respondents are university graduates. Cold (18.8%) and sore throat (13.0%) were the diseases commonly found among the community that drove them to using non-prescribed antibiotics. About 337 (72.8%) of the respondent mention the use of antibiotics to treat the illness, and 21 (4.5%) were aiming to prevent the illness. While, 19.4% of the respondents admitted to taking non-prescribed antibiotics for both prevention and treatment of illness. 43.6% of the respondents disclosed that they are not aware of the dangers of using non-prescribed antibiotics. In conclusion the use of non-prescribed antibiotics in this community is evident, as a significant number use them from previous experience for prevention and treatment of illness. Therefore introduction of rational use of drugs will help in limiting the attendant development of bacterial resistance
Inhibitory Potential of Mangiferin on Glucansucrase Producing Streptococcus mutans Biofilm in Dental Plaque
No full textGlucansucrase secreted by Streptococcus mutans and composed of virulence genes alters oral microbiota, creating adherent environment for structural bacteria colony forming dental biofilm. The present investigation studied the inhibitory and binding potentials of mangiferin against S. mutans and its enzyme glucansucrase implicated in biofilm formation. Antibacterial activity against planktonic S. mutans was carried out. Using reverse transcription PCR, the expression of crucial virulence genes, gtfB, gtfC, gtfD, gbpB, and comDE were determined. The effect of mangiferin on teeth surfaces biofilm was ascertained by scanning electron microscopy (SEM). Docking analysis of S. mutans glucansucrase and mangiferin revealed the binding energy of −7.35 and ten hydrogen interactions. Antibacterial study revealed that mangiferin was not lethal to planktonic S. mutans, but a concentration-dependent inhibition of glucansucrase activity was observed. The inhibitory effect of water-insoluble glucan synthesis was apparently more marked relative to water-soluble glucan synthesis attenuation. Mangiferin significantly downregulated the expression of the virulence genes, indicating a mechanism involving glucanotranferases, specifically inhibiting colony formation by attenuating bacterial adherence. SEM images revealed that S. mutans biofilm density was scanty in mangiferin treated teeth compared to non-treated control teeth. Our data therefore suggest that mangiferin inhibited S. mutans biofilms formation by attenuating glucansucrase activities without affecting bacteria growth
Anti-Allergic Potential of Cinnamaldehyde via the Inhibitory Effect of Histidine Decarboxylase (HDC) Producing Klebsiella pneumonia
No full textAllergy is an immunological disorder that develops in response to exposure to an allergen, and histamines mediate these effects via histidine decarboxylase (HDC) activity at the intracellular level. In the present study, we developed a 3D model of Klebsiella pneumoniae histidine decarboxylase (HDC) and analyzed the HDC inhibitory potential of cinnamaldehyde (CA) and subsequent anti-allergic potential using a bacterial and mammalian mast cell model. A computational and in vitro study using K. pneumonia revealed that CA binds to HDC nearby the pyridoxal-5′-phosphate (PLP) binding site and inhibited histamine synthesis in a bacterial model. Further study using a mammalian mast cell model also showed that CA decreased the levels of histamine in the stimulated RBL-2H3 cell line and attenuated the release of β-hexoseaminidase and cell degranulation. In addition, CA treatment also significantly suppressed the levels of pro-inflammatory cytokines TNF-α and IL-6 and the nitric oxide (NO) level in the stimulated mast cells. A gene expression and Western blotting study revealed that CA significantly downregulated the expressions of MAPKp38/ERK and its downstream pro-allergic mediators that are involved in the signaling pathway in mast cell cytokine synthesis. This study further confirms that CA has the potential to attenuate mast cell activation by inhibiting HDC and modifying the process of allergic disorders
A Molecular Insight into the Synergistic Mechanism of Nigella sativa (Black Cumin) with β-Lactam Antibiotics against Clinical Isolates of Methicillin-Resistant Staphylococcus aureus
No full textMethicillin-resistant Staphylococcus aureus (MRSA) infection is detrimental to hospitalized patients. With diminishing choices of antibiotics and the worry about resistance to colistin in synergistic combined therapy, there are suggestions for the use of herbal derivatives. This investigation evaluated the synergistic effects of Nigella sativa (NS) in combination with beta-lactam (β-lactam) antibiotics on extreme drug-resistant (XDR) MRSA isolates. NS concentrations of 10, 7.5, 5.0, 2.5, 1.0, and 0.1 µg/mL, alone and in combination with β-lactam antibiotics, were used to determine the antimicrobial susceptibility of MRSA isolates by the well diffusion method. Time–kill assays were performed using a spectrophotometer, with time–kill curves plotted and synergism ascertained by the fractional inhibitory concentration (FIC). Scanning and transmission electron microscopy were used to gain insight into the mechanism of action of treated groups. Isolates were inhibited by the NS concentrations, with differences in the zones of inhibition being statistically insignificant at p < 0.05. There were statistically significant differences in the time–kill assay for the MRSA isolates. In addition, NS combined with augmentin showed better killing than oxacillin and cefuroxime. The mechanism of action shown by the SEM and TEM results revealed cell wall disruption, which probably created interference that led to bacterial lysis
Rutin-Activated Nuclear Factor Erythroid 2-Related Factor 2 (Nrf2) Attenuates Corneal and Heart Damage in Mice
No full textBackground: Corneal degeneration is a form of progressive cell death caused by multiple factors, such as diabetic retinopathy. It is the most well-known neural degenerative disease caused by macular degeneration in the aged and those with retinitis pigmentosa. Myocardial infarction is becoming a more common burden, causing cardiomyocyte degeneration, ischemia, and heart tissue death. This study examined the preventive effects of rutin on isoproterenol (ISO)-induced oxidative damage (that is, inflammation) on rabbit corneal epithelial cells and mouse heart injuries. Methods: These investigations involved a cytotoxicity test, biochemical analysis, qRT-PCR, Western blotting, and mouse cardiac histopathology. Results: The results showed that rutin enhanced ADH7 and ALDH1A1, retinoic acid signaling components in SIRC1 rabbit corneal cell lines. The production of NO by ocular epithelial cells was significantly reduced. It reduced cTnT and cTnI, CK-MB, and LDH contents in mouse cardiac tissue. The nuclear expressions of Nrf2, Sirt, and HO-1 were all increased by rutin. Docking studies revealed a good interaction between rutin and the Keap protein, enhancing Nrf2 nuclear activity. Conclusions: This showed that rutin can potentially enhance ADH7 and ALDH1A1 corneal signaling components, preventing corneal degeneration and mitigating ISO-induced myocardial infarction (MI) via Keap/Nrf2 expressions
The public purchase of aphrodisiac products without prescriptions in the Alahsa region of KSA
No full textAbstractObjectivesTo investigate requests for common prescription-only aphrodisiacs across community pharmacies in the Alahsa region of KSA.MethodsA cross-sectional study was conducted among conveniently selected pharmacies in the eastern region of Alahsa, KSA. Self-administered questionnaires were directly distributed to 73 consenting community pharmacies. Completed questionnaires were coded, reviewed for accuracy and entered into a database in Statistical Package for the Social Sciences (Version 19.0; IBM Corporation, Somers, NY). The data were analysed using descriptive analysis.ResultsThe survey response rate was 72.60%. With respect to the availability of aphrodisiacs and sexual supplements, most of the pharmacists disclosed that they had stocks of Viagra and Cialis. The most common men's health complication reported by pharmacists was erectile dysfunction (n = 12, 22.6%), followed by premature ejaculation (n = 4, 7.5%) and low sexual desire (n = 1, 1.9%). Less than half of pharmacists (n = 9, 16.9%) cited Viagra and Cialis as preferred drugs for treating premature ejaculation. Approximately 32 (60.3%) proposed delayed sprays as the first line of action, while 13 (24.5%) considered antidepressants as their first-choice drug.ConclusionThe non-prescription dispensing of prescription-only medicines, including sexual enhancement products, is common in KSA. The majority of pharmacists continue to violate pharmaceutical laws without recognizing the potential harm they are causing their communities. Stakeholders should organize training and certification initiatives to ensure that pharmacists are aware of and comply with national pharmaceutical laws. These agencies should also ensure that pharmacies maintain safe and ethical practices
