2023
Chłopecka Magdalena | Kiraga Łukasz | Crowley Kijan | Jank Michał | Latek Urszula | Mendel Marta | Karlik Wojciech
Due to the growing interest in the use of cannabinoids in supportive therapies, they are increasingly used together with anti-inflammatory drugs. Cannabinoids inhibit gastrointestinal motility, while steroidal and nonsteroidal anti-inflammatory drugs influence motility in other ways. The aim of the research was to study the interactions between cannabidiol (CBD) and these two classes of anti-inflammatory drugs in the context of gastrointestinal motility. Dexamethasone (DEX) was selected as a steroidal drug and diclofenac (DCF) as a nonsteroidal counterpart.

Because of the activities and effects they induce, hormones are prohibited for use for anabolic purposes in farm animals intended for slaughter, which is regulated in the European Union by relevant legal provisions. Therefore, there is an obligation to monitor residues of hormones in animals and food of animal origin to ensure consumer safety. A hormone banned but used formerly for fattening cattle, stanozolol, and its metabolite 16β-OH-stanozolol are synthetic compounds that belong to a large group of steroid hormones. This study investigates residues of these compounds in animal urine.

2023
Lee Ji-Hye | Kim Sang-Hwan
The formation and function of the corpus luteum (CL) increase the likelihood of pregnancy and efficiently manage implantation. Apoptosis must occur at an appropriate time in the formation of the CL. This also affects its function. However, it is still unclear if the type of apoptosis affects the function.

Metabolic syndrome (MetS) is a cluster of pathological conditions well described in humans but still investigated insufficiently in animals. A novel approach in its management is the utilisation of nutrients from natural sources. Recent studies suggested that phenolic compounds from pomegranate peel could be a promising dietary intervention for MetS. This study evaluated the potency of polyphenol-rich pomegranate peel extract (EPP) in mitigating some MetS components in an animal model.

Streptococcus agalactiae (S. agalactiae) is a pathogen causing bovine mastitis that results in considerable economic losses in the livestock sector. To understand the distribution and drug resistance characteristics of S. agalactiae from dairy cow mastitis cases in China, multilocus sequence typing (MLST) was carried out and the serotypes and drug resistance characteristics of the bacteria in the region were analysed.

Mikołajczyk Szczepan | Warenik-Bany Małgorzata | Pajurek Marek
Concentrations of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) were investigated in six species of bivalve mollusc purchased on the Polish retail market. The risk to consumers was calculated as a percentage of the tolerable weekly intake (TWI) (2 pg World Health Organization toxic equivalent (WHO-TEQ) kg−1 body weight (b.w.)).

Appendicular osteosarcoma (OSA) is a highly aggressive and metastatic primary bone tumour in dogs. Standard therapy is amputation and adjuvant chemotherapy (e.g. with doxorubicin). Liposomal drug delivery may augment therapeutic efficacy and reduce negative side effects. Polyethylene glycol (PEG)-liposomal doxorubicin treats human metastatic cancers effectively. The study aimed was to evaluate PEG-liposomal doxorubicin’s inhibitory effect on canine metastatic proliferation and migration in vitro. It also aimed to appraise the drug’s extravasation inhibition in vivo using the human medicine–proven chick embryo chorioallantoic membrane ex ovo model.

Kazuń Barbara | Kazuń Krzysztof | Małaczewska Joanna | Kamiński Rafał | Adamek-Urbańska Dobrochna | Sikorska Justyna | Wolnicki Jacek | Szudrowicz Hubert
The experiment was set to determine the effects of long-term (55-day) use of three commercial prebiotics including Saccharomyces cerevisiae–derived β-glucans and one including inulin on juvenile vimba (Vimba vimba) reared intensively under controlled conditions.

Zorić Jelena Maksimović | Veljović Ljubiša | Radosavljević Vladimir | Glišić Dimitrije | Kureljušić Jasna | Maletić Jelena | Savić Božidar
Swine influenza A viruses (swIAVs) are characterised by high mutation rates and zoonotic and pandemic potential. In order to draw conclusions about virulence in swine and pathogenicity to humans, we examined the existence of molecular markers and accessory proteins, cross-reactivity with vaccine strains, and resistance to antiviral drugs in five strains of H1N1 swIAVs.

2023
Niedźwiedzka-Rystwej Paulina | Deptuła Wiesław
Lagovirus europaeus is a single-stranded RNA virus causing an acute fatal disease in wild and domestic rabbits around the world. Studies have shown that the pivotal process impacting the immune response against the disease is apoptosis, registered mainly in hepatocytes and in peripheral blood, together with an increased number of cytotoxic lymphocytes (CTLs). It is known that cytotoxic lymphocytes can induce target cells to undergo apoptosis on the pseudoreceptor pathway, such apoptosis having been found in several acute and chronic viral infections. The study aimed to assess the crosstalk between the apoptosis of peripheral blood lymphocytes and CD8+ T lymphocytes (as CTLs) in rabbits infected with 6 Lagovirus europaeus GI.1a viruses.
