Summary: Methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of infectious diseases in humans and animals, resulting in economic losses in human healthcare and the farming sector. The changing epidemiology of MRSA globally affects animal welfare and public health concerns. Livestock have high rates of MRSA colonization, raising questions about reservoirs and transmission, while companion animals vary in MRSA colonization and infection rates, impacting human health. This article highlights the circulation of animal-associated MRSA (AA-MRSA) in the environment and factors influencing its transmission, as well as successful strategies to limit its spread among animals and humans.

Summary: Staphylococcus aureus (S. aureus) is a dangerous bacterial pathogen that can infect both humans and animals. Methicillin-resistant S. aureus (MRSA) is classified into different types based on their sources, such as hospital-associated (HA-MRSA), community-associated (CA-MRSA), and livestock-associated MRSA (LA-MRSA). LA-MRSA, initially associated with livestock, has spread among humans, animals, and the environment due to factors like animal husbandry, globalization, and antibiotic use. This review provides an overview of the transmission characteristics of S. aureus and its clones in different hosts, as well as the changes in mobile genetic elements (MGEs) during host switching.

Summary: This study successfully synthesized a novel graphene/chitosan/beta-cyclodextrin composite material (GO/CS/beta-CD) via a one-step chemical reduction method, combining the advantages of graphene, chitosan, and beta-cyclodextrin. The composite was characterized using techniques such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy. Sortase A (SA) was immobilized onto the GO/CS/beta-CD for the detection of Staphylococcus aureus, showing a good linear relationship within the concentration range of 30-300 CFU/mL and a detection limit of 12 CFU/mL. The GO/CS/beta-CD composite material, with immobilized sortase A, demonstrated enhanced sensitivity and selectivity for the detection of Staphylococcus aureus.

Summary: Chemotherapy-related cognitive impairment (CRCI) has become a focus of research in the past years due to its potential adverse effects on breast cancer patients. This review provides an overview of the molecular mechanisms linking individual drugs used in breast cancer treatment to CRCI, the clinical characteristics of CRCI in patients, and possible therapeutic interventions. The incidence rates of CRCI in breast cancer vary considerably and may affect more than 50% of treated patients. Although there is currently no standard treatment for CRCI, various pharmacological and non-pharmacological approaches have shown promising results.

Summary: This study developed a lipid-based nanocarrier loaded with clioquinol (CQ) for the treatment of skin fungal infections and evaluated its antifungal activity. The CQ-loaded nanocarrier was able to reduce the minimum inhibitory concentration (MIC) in most tested strains and exhibited stable fungistatic action. These findings suggest that the CQ-loaded nanocarrier is a promising treatment for skin fungal infections and a potential candidate for future randomized clinical trials.

Summary: This study evaluates the antimicrobial activity of three 8-hydroxyquinoline derivatives against Pythium insidiosum and determines their pharmacodynamic characteristics. Results show that Clioquinol, PH151, and PH153 are active against all isolates, with MIC values ranging from 0.25 to 2 μg/mL. They also exhibit a time- and dose-dependent antimicrobial effect, damaging the P. insidiosum cell wall. These findings reinforce the potential of 8-hydroxyquinoline derivatives as new drugs for treating pythiosis.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.

Summary: This study aims to develop a nano-biofungicide comprising of volatile essential oil molecules to enhance its efficacy in the field of agriculture through easily scalable green synthesis technique. The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
