Ten Years of African Swine Fever in Ukraine: An Endemic Form of the Disease in the Wild Boar Population as a Threat to Domestic Pig Production.

(1) Background: African swine fever (ASF) has been present in Ukraine for more than ten years (2012-2022). The purpose of our study was to perform a retrospective analysis of the spread of ASF to assess the role of wild boar in the epizootic expansion in Ukraine. (2) Methods: Statistical materials were collected and the epizootic situation of ASF from 2012 to 2022 was examined.

Levels of spexin and its receptors GALR2 and GALR3 in the hypothalamus and ovary of letrozole-induced polycystic ovary syndrome in rats.

Spexin (SPX) is a newly identified neuropeptide, a natural ligand for the galanin receptors (GALR) 2/3, which is involved in maintaining physiological functions including female reproduction. One of the most common endocrine disorder in reproductive system is polycystic ovary syndrome (PCOS), however the role of SPX in PCOS is still unknown. The objective of this study was to determine the expression of mRNA and peptide levels of SPX and its receptors GALR2/3 in the hypothalamus and ovary (by real time PCR and Western blot) as well as plasma levels of SPX (ELISA) in letrozole - induced PCOS rats.

Tracking the Molecular Scenarios for Tumorigenic Remodeling of Extracellular Matrix Based on Gene Expression Profiling in Equine Skin Neoplasia Models.

An important component of tissues is the extracellular matrix (ECM), which not only forms a tissue scaffold, but also provides the environment for numerous biochemical reactions. Its composition is strictly regulated, and any irregularities can result in the development of many diseases, including cancer. Sarcoid is the most common skin cancer in equids.

Methylation Status of Gene Bodies of Selected microRNA Genes Associated with Neoplastic Transformation in Equine Sarcoids.

Horses are of great importance in recreation, livestock production, as working animals in poorly developed countries, and for equine-assisted therapy. Equine sarcoids belong to the most commonly diagnosed tumors in this species. They may cause discomfort, pain, and can lead to the permanent impairment of motor function.

Assessment of Mediated Matrix Metalloproteinase Genes Deregulation in the In Vivo and In Vitro Models Designed to Explore Molecular Nature of Equine Sarcoids.

Matrix metalloproteinases (s) represent a family of enzymes capable of biocatalytically breaking down the structural and functional proteins responsible for extracellular matrix (ECM) integrity. This capability is widely used in physiological processes; however, imbalanced MMP activity can trigger the onset and progression of various pathological changes, including the neoplasmic transformation of different cell types. We sought to uncover molecular mechanisms underlying alterations in transcriptional profiles of genes coding for s, which were comprehensively identified in equine adult dermal tissue bioptates, sarcoid-derived explants, and ex vivo expanded adult cutaneous fibroblast cell (ACFC) lines subjected to inducible oncogenic transformation into sarcoid-like cells.

in Pig Farms Suspected of Porcine Circovirus Type 2 (PCV2) Associated Enteritis.

Introduction: Diarrhoea in growing-finishing pigs is a common problem of commercial pig farms. Among many causative factors, porcine circovirus type 2 (PCV2) is one considered an important pathogen in modern pig production. The aim of the study was to verify if PCV2 was responsible for antibiotic non-responsive diarrhoea and wasting in pigs.

Levels of the neuropeptide phoenixin-14 and its receptor GRP173 in the hypothalamus, ovary and periovarian adipose tissue in rat model of polycystic ovary syndrome.

Phoenixin (PNX) is a newly discovered peptide produced by proteolytic cleavage of a small integral membrane protein 20 (Smim20), which acts as an important regulator of energy homeostasis and reproduction. Since dysfunction of reproduction is characteristic in polycystic ovarian syndrome (PCOS), the role of PNX in pathogenesis of PCOS needs further investigation. The objective of this study was to determine expression of Smim20, PNX-14 and its receptor GRP173 in the hypothalamus, ovary and periovarian adipose tissue (PAT) of letrozole induced PCOS rats.

Dynamics of pro- and anti-inflammatory cytokine changes in serum and assessment of their diagnostic utility during lactation impairment in pigs.

Postpartum dysgalactia syndrome (PDS) in sows is a frequent and important clinical problem in the field. Currently, the diagnosis is based on physical examination performed during first days after the farrowing. The present study aimed at evaluation the dynamics of pro- and anti-inflammatory cytokine (IL-4, IL-6, IL-8, IL-10 and TNF-α) changes in serum of sows during peripartum period (day - 28 to + 28) and assessment of their diagnostic utility during lactation impairment in pigs.

Tulathromycin enhances humoral but not cellular immune response in pigs vaccinated against swine influenza.

The effect of a standard, single dose therapy with tulathromycin was investigated on the postvaccinal humoral and cellular immune response in pigs vaccinated against swine influenza. Forty-five pigs, divided into 3 groups, were used (control not vaccinated (C, n = 15), control vaccinated (CV, n = 15), and experimentally received tulathromycin (TUL, n = 15)). For vaccination of pigs, an inactivated, commercial vaccine was used.
