Retention mechanisms of tetracyclines on a C8 reversed-phase material

, 1980
The influence of eluent parameters on the retention of tetracyclines on a C8 reversed-phase column has been investigated. Optimal performance was obtained using eluents containing organic acids at relatively low pH, where the solutes mainly exist in ...

The Preparation of Novel Fluorenes Inspired by Hipposudoric Acid

Helvetica Chimica Acta, EarlyView.
In this research we report on the design and synthesis of a series of fluorene‐based derivatives loosely inspired by the tricyclic framework of hipposudoric acid. Preparation of sixteen novel N‐alkylated derivatives was accomplished via a series of concise one‐step amide N‐alkylation reactions.

Safety of Prenatal Anti‐Infective Use and Offspring Outcomes: A Panoramic Assessment by Indication, Drug Class, and Exposure Characteristics

iMetaMed, EarlyView.
Based on the comprehensive, panoramic assessment of the safety of prenatal anti‐infective use across indications, drug classes, and exposure characteristics, potential safety signals associated with prenatal exposure to several widely used anti‐infective drug classes were identified, including macrolides, metronidazole, tetracyclines, sulfonamides ...

Metagenomic and culture‐based insights into host and plasmid contexts of high‐risk ARGs in poultry farm environments

iMetaOmics, EarlyView.
Shotgun metagenomics and culture‐based isolate genomics revealed position‐associated high‐risk antibiotic resistance genes (ARGs) signals across poultry manure piles and surrounding soils. Culture‐confirmed Enterobacteriaceae and IncHI2A‐related blaNDM‐5 plasmid backgrounds further highlight priority host‐ARG‐plasmid contexts for farm antimicrobial ...

Gingival inflammation and plaque accumulation affect therapeutic outcomes in patients with acne vulgaris

Journal of Periodontology, EarlyView.
Abstract Background We hypothesized that acne vulgaris (AV) and gingivitis were associated through systemic inflammatory mechanisms, sharing common etiological factors. This study aimed to identify the association between AV and gingivitis and to assess changes in acne severity in relation to changes in the plaque index (PI).

Metabolomic insights for the authentication and traceability of antibiotic‐free pork: a pilot study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Antibiotic‐free production within the meat supply chain is a source of concern since new voluntary label claims need to be authenticated to prevent fraud. Therefore, an untargeted 1H NMR‐based metabolomics approach coupled to unsupervised (principal component analysis) and supervised (orthogonal partial least squares discriminant ...

Nail Toxicities Associated With Anticancer Therapies in Children

JEADV Clinical Practice, EarlyView.
ABSTRACT Nail toxicities are a frequent yet often underrecognized component of dermatologic adverse events in children receiving anticancer therapies. Both conventional cytotoxic chemotherapy and newer targeted agents can affect the nail matrix, nail bed and periungual tissues, producing a broad spectrum of clinical manifestations that range from ...

Use of a Bacteriophage Lysin to Control Axillary Malodor

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Axillary malodor is primarily caused by bacteria, particularly Staphylococcus hominis, which metabolize apocrine secretions into volatile compounds. Traditional deodorants contain antiseptics that can disrupt the skin microbiome and cause irritation. Alternative methods of odor control are being sought but so far without success. We

(Bio)Electroanalysis of Tetracyclines: Recent Developments

Tetracyclines (TCs) are antibiotics used extensively in medicine, veterinary science, and animal husbandry. Their overuse and the widespread presence of their residues in the environment contribute to intensifying the phenomenon of antibiotic resistance (
