Simultaneous and on-line detection of organic and heavy metal components in water using a novel nebulization-assisted injection plasma ionization triple quadruple mass spectrometry instrument
In this study, an analytical technique of nebulization-assisted injection plasma ionization mass spectrometry (NI-PIMS) was developed. This novel method enables the simultaneous detection of heavy metals and organic compounds in water system with high sensitivity, which has been demonstrated by the limit of quantification (LOQ) values below 1.0 μg/L for the three sterols (Enrofloxacin, ciprofloxacin, and clenbuterol) and three heavy metals (Pb, Ba, and Cd). Moreover, the method was successfully applied to rapidly analyze real water samples from urban and rural areas in China. The analytical results are available in less t...

Synergistic Inhibitions of Gram-negative Bacteria by Combination Treatment with Ciprofloxacin and a Novel Glucolipid
Chem Biodivers. 2024 Apr 17:e202400578. doi: 10.1002/cbdv.202400578. Online ahead of print.ABSTRACTPsychrophilic fungus Pseudogymnoascus sp. OUCMDZ-4032 derived from Antarctica was cultivated under 16 ℃ to produce a new glucolipid compound (1). Its structure was elucidated by analysis of detailed spectroscopic data, acid hydrolysis and 1-phenyl-3-methyl-5-pyrazolone precolumn derivatization, and 13C NMR quantum chemical calculations. Though compound 1 did not show inhibitory activity against bacteria, it can reduce the minimum inhibitory concentration (MIC) of ciprofloxacin against Gram-negative bacteria Pseudomonas aeru...

Minimum inhibitory concentrations of Neisseria gonorrhoeae strains in clients of the Amsterdam sexual health clinic with a Dutch versus an international sexual network
Conclusions
For three cephalosporin antibiotics, we found Ng strains with slightly higher MICs in clients with partner(s) from Europe or Latin America and the Caribbean. International travel might contribute to the spread of Ng with lower susceptibility. More understanding of the emergence of AMR Ng is needed. (Source: Sexually Transmitted Infections)

Challenges in the treatment of pediatric Mycoplasma pneumoniae pneumonia
Conclusion: This report summarizes the clinical significance of macrolide-resistant and refractory MP pneumonia and discusses the efficacy and safety of alternative drugs, with a stepwise approach to the management of MP pneumonia recommended from the viewpoint of clinical practice.What is Known:•Although MP pneumonia is usually a benign self-limited infection with response macrolides as first line therapy,severe life-threatening cases may develop if additional treatment strategies are not effectively implemented.•Macrolide-resistant and refractory MP pneumonia are two conditions that may complicate the clinical cour...

In vitro antibacterial activity of antibiotics and plant essential oils against Escherichia coli MTCC443 supported through the molecular docking and pharmacokinetics study
This study has been made to compare the in vitro antibacterial activity and further validated the same through the molecular docking study of 13 antibiotics such as ciprofloxacin, chloramphenicol, erythromycin, ampicillin, cefotaxime, rifampicin, kanamycin, vancomycin, streptomycin, penicillin, nalidixic acid, trimethoprim, and polymyxin, and 10 EOs such as garlic, tulsi, neem, clove, thyme, peppermint, coriander, tea, lavender, and eucalyptus against the target protein (DNA gyrase) ofE. coli MTCC443.E. coli Microbial Type Culture Collection 443 was found to be highly sensitive to ciprofloxacin (zone of inhibition [ZOI], 2...

Predominance of multidrug-resistant < i > Salmonella < /i > Typhi genotype 4.3.1 with low-level ciprofloxacin resistance in Zanzibar
ConclusionsWe report a high rate of MDR and low-level ciprofloxacin resistantS. Typhi circulating in Zanzibar, belonging to genotype 4.3.1.1, which is widespread in Southeast Asia and African countries and associated with low-level ciprofloxacin resistance. Few therapeutic options are available for treatment of typhoid fever in the study setting. Surveillance of the prevalence, spread and antimicrobial susceptibility ofS. Typhi can guide treatment and control efforts. (Source: PLoS Neglected Tropical Diseases)

Six-year progression of medically treated infective aortitis
CONCLUSIONS: Infective aortitis with mycotic aneurysms is usually treated surgically due to the significant risk of rupture in the acute period. This case suggests that if the acute infective period is passed, the aneurysmal disease stabilises and does not progress.PMID:38626935 | DOI:10.1177/17085381241248724 (Source: Vascular)
