Article Abstract
The presence of fluoroquinolone (FQ) residues in food-producing animals has raised concerns regarding antimicrobial resistance. This study evaluated the occurrence of FQ residues in the liver and kidneys of piglets and their association with resistance patterns in and species from piglets' intestinal microbiota. FQ residues were found in 44% of livers and 23% of kidneys. Among 340 isolates from feces, resistance to ciprofloxacin (CIP) (43.2%) and multidrug resistance (MDR) (82.7%) were prominent. The presence of FQ in kidneys significantly increased the odds of CIP-resistant (OR = 2.94, = 0.0013) and MDR (OR = 2.70, = 0.0047). Enterococci ( = 130) were evenly distributed among the species , , and spp. and presented resistance to CIP (34.6%). FQ in kidneys were associated with higher odds of CIP-resistant enterococci (OR = 3.78, = 0.015). Interaction models revealed species-dependent responses, with spp. showing high resistance in the presence of FQ in kidneys (OR = 18, = 0.006), while exhibited lower resistance compared to . These findings emphasize the role of FQ residues in promoting bacterial resistance and underscore the need for the stricter regulation and routine surveillance of antimicrobial use in livestock to curb the spread of bacterial resistance to clinical drugs, and mitigate public health risks-One Health.

Rac1 palmitoylation is required for cardiac stress adaptation and regulation of Protein Kinase A signaling.

Cardiac hypertrophy is a common adaptation to cardiovascular stress and often a prelude to heart failure. We examined how S-palmitoylation of the small GTPase, Ras-related C3 botulinum toxin substrate 1 (Rac1), impacts cardiomyocyte stress signaling. Mutation of the cysteine-178 palmitoylation site impaired activation of Rac1 when overexpressed in cardiomyocytes.

The strong C-F bond found in per- and poly-fluorinated alkyl substances (PFAS) makes them resistant to degradation and thus persistent in the environment. One of the most common methods for quantifying PFAS in environmental matrices is to use tandem mass spectrometry. However, the dissociation of ions made by deprotonating PFAS alcohols and acids has only been qualitatively explored.

Marine-derived enzymes often show distinct physiological properties and great potential for industrial use. Salt ions may improve the stability and expression efficiency of marine enzymes, which requires salt-resistant host based expression platform. Aspergillus oryzae of good protein expression and secretion was evaluated and explored for this purpose.

Anaerobic bacteria cause a wide range of infections, varying from mild to severe, whether localized, implant-associated, or invasive, often leading to high morbidity and mortality. These infections are challenging to manage due to antimicrobial resistance against common antibiotics such as carbapenems and nitroimidazoles. The empirical use of antibiotics has contributed to the emergence of resistant organisms, making the identification and development of new antibiotics increasingly difficult.
