The study employed random allocation of test sites using Microsoft Excel software. Both investigators and participants were blinded to the treatment assignments. The main outcomes were changes in skin hydration and transepidermal water loss (TEWL), measured with non-invasive probes (Corneometer CM 825, Tewameter TM 300), and erythema measured by Mexameter MX 18. Following irritant exposure, all sites showed increased TEWL and reduced hydration, confirming skin barrier impairment. The intervention site demonstrated significantly greater hydration compared with both the control (p = 0.017) and placebo sites (p = 0.035) on day 4, with this improvement persisting on day 8 (p = 0.043). TEWL values at the intervention site were significantly lower than control on day 3 (p = 0.022), indicating faster barrier recovery. No significant differences in erythema were observed between groups, and no adverse events occurred. Results of this study indicate that the addition of 1 % Calendula officinalis extract to an emollient cream enhanced skin hydration and accelerated recovery after irritant exposure, suggesting potential benefit in managing contact dermatitis with non-pharmacological skincare formulations.","PeriodicalId":7034,"journal":{"name":"Acta Pharmaceutica","volume":"75 4","pages":"699-708"},"PeriodicalIF":1.4,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145958255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antibiotic susceptibility testing revealed consistent resistance to colistin, as well as significant resistance rates to β-lactam antibiotics, ertapenem, amoxicillin/clavulanic acid, ticarcillin and ampicillin. High susceptibility to first-generation cephalosporins, cephalexin, cefoxitin and chloramphenicol was observed. All isolates were susceptible to tigecycline and tetracycline. The isolates were grouped into three genetically closely related clusters, yet notable phenotypic diversity in biofilm production and antibiotic susceptibility persisted within these groups.

In the first step of the study, the minimum inhibitory concentrations (MICs) of 2-HNQ and 2-MNQ were determined using the microdilution method. Subsequently, possible mechanisms underlying the antibacterial activity of 2-HNQ and 2-MNQ against E. coli were investigated by assessing intracellular reactive oxygen species (ROS) production and membrane permeability. Finally, the impact of 2-HNQ and 2-MNQ on swarming motility and on pre- and post-biofilm formation of E. coli was evaluated. The MIC of 2-HNQ against E. coli was 500 µg mL-1, while that of 2-MNQ was 100 µg mL-1. Both compounds increased intracellular ROS production and altered the membrane permeability of E. coli. Moreover, 2-HNQ and 2-MNQ reduced swarming motility and inhibited both pre- and post-biofilm formation. The results of this study indicate that both naphthoquinones possess antibacterial potential, with 2-MNQ showing greater potency against E. coli. Their antibacterial activity appears to involve ROS generation and disruption of membrane permeability. Importantly, both tested naphthoquinones also impaired E. coli motility and bio-film formation, suggesting potential applications in the treatment of infections caused by E. coli.","PeriodicalId":7034,"journal":{"name":"Acta Pharmaceutica","volume":"75 4","pages":"629-641"},"PeriodicalIF":1.4,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145958301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These effects are mediated through opioid receptors and can be abolished by the opioid receptor antagonist naltrexone. Investigation of peptide enantiomerism and the incorporation of d-amino acids are crucial for designing novel peptides with altered structural and biological properties compared with their native l-forms. Since no data are currently available on the properties or biological activity of the d-Met-enkephalin enantiomer, we evaluated its hepatoprotective potential in a mouse model of acetaminophen-induced hepatotoxicity. Male CBA mice were treated with d-Met-enkephalin, and hepatoprotection was assessed by measuring plasma alanine aminotransferase (ALT) and aspartate amino-transferase (AST) activities, along with histological liver necrosis scores. The peptide's secondary structure and antisense peptide binding were analysed using circular dichroism and fluorescence spectroscopy, respectively. d-Met-enkephalin demonstrated dose-dependent hepatoprotective effects within the range of 0.5-20 mg kg-1, with maximal protection observed at 5 mg kg-1, a dose comparable to that of the l-enantiomer (7.5 mg kg-1). This preservation of biological activity may be attributed to the presence of the achiral amino acid glycine at positions 2 and 3, which maintains the functional conformation of the d-enantiomer. The role of opioid receptor involvement was further examined through direct receptor blockade using naltrexone and indirect inhibition with the antisense peptide IPPKY.","PeriodicalId":7034,"journal":{"name":"Acta Pharmaceutica","volume":"75 4","pages":"659-672"},"PeriodicalIF":1.4,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145958393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
