Flaxseed is an important supplement in animal feed. It contains high levels of polyunsaturated fatty acids and lignans acting as phytoestrogens, which can alter cell functions in various organs. The aim of this work was to analyse the effect of supplemental flaxseed in pigs on the morphophysiological properties of the uterus. The experiment include...
Dietary fatty acids (FA) have an effect on animal reproduction. The purpose of the study was to find out how supplemental flaxseed can modulate the FA metabolism and how FA can influence the release of ovarian hormones and functions of the uteri through the modulation of their specific receptors. Cycling mice were fed a basal diet (control) and bas...
Carbon monoxide (CO) has been proposed as a chemical light signal and neural system modulator via heme oxygenases -1 and -2 (HO-1 and HO-2). Many papers have proven the CO-HO circuit to be important for such physiological pathways as the molecular biological clock and the GnRH axis, but also in such pathological occurrences as ischemic injuries, or...
Mature males of a wild boar-pig crossbreed during long- and short-day seasons were used for the study, which demonstrated that the chemical light carrier CO regulates the expression of biological clock genes in the hypothalamus (preoptic area - POA and dorsal part of hypothalamus - DH) via humoral pathways. Autologous blood with experimentally elev...
Bacground: The master biological clock (pacemaker) is located in the suprachiasmatic nuclei (SCN) of the preoptic part of the hypothalamus (POA) and makes organisms adjust to the rhythms, both annual and circadian. Intrinsic pacemaker function is based on the 24-hour oscillator of the transcription factor genes Bmal1/Clock or its paralog Npas2 in w...
Xylene is a common pollutant in the environment that enters the body of animals and humans in various ways, but most often through the respiratory tract and adversely affects their overall health. However, xylene effects after oral exposure have not been sufficiently studied. This study aimed to investigate the effects of xylene exposure on the mou...
Circadian clock genes are found in almost every cell that has a nucleus; they regulate the rhythmic nature of all processes that are cyclical. Among the genes controlled by the circadian clock, there are numerous factors that regulate key processes in the functioning of the cell. Disturbances in the functioning of the circadian clock are associated...
The electromagnetic field (EMF) is an environmental factor affecting living organisms. The aim of this study was to demonstrate the effect of an extremely low frequency electromagnetic field (ELF-EMF) on selected chemical components of the honeybee (Apis mellifera L.) using Fourier Transform Infrared (FTIR) spectroscopy. The FTIR method provides in...
Pathological processes that strongly affect the uterine endometrium lead to infertility and abortion. The most common of these pathologies are clinical and subclinical endometritis. Subclinical endometritis is characterized by endometrial inflammation in the absence of clinical signs of endometritis. In this study, we used uterine samples obtained...
The aim of this study was to examine novel putative markers of the response to the competitive soccer match in adolescent players, such as changes in global levels of γH2AX and H4K16ac in the chromatin of peripheral mononuclear blood cells (PMBCs) and a Fourier-transform infrared spectroscopy (FTIR)-based biochemical fingerprint of serum. These cha...
The purpose of these laboratory tests was to assess the impact of 50 Hz EMF (electromagnetic field) on the disappearance of azoxystrobin (active ingredient (AI) of Amistar 250 SC) and λ-cyhalothrin (AI of Karate Zeon 050 CS) in the body of honey bees (Apis mellifera) and the structure of some functional groups of the probabilistic molecules in thei...
Melatonin regulates male reproductive function in seasonal and non-seasonal breeder mammals. The presence of melatonin membrane receptors (MT1 and MT2) in the testis and epididymis has been demonstrated in several species. Wild roe deer are a short-day breeding species characterised by a short rutting season lasting from mid-July to mid-August. The...
Electromagnetic fields (EMF) are classified as an environmental factor affecting living organisms. The aim of the study was to evaluate the effect of EMF at different frequencies (50 and 120 Hz), durations of treatment (2 and 4 h) and with the magnetic induction of 8 m T on testicular tissues of roe deer (Capreolus capreolus) in vitro by comparison...
Background and purpose:
Several members of the core clock mechanism are equipped with a Per-Arnt-Sim (PAS) domain through which they can bind haem [Fe(II)]. Haem is a ligand for the orphan receptors REV-ERBα/β (NR1D1/2), which regulate circadian rhythm and metabolism. The ability to bind haem sensitises these clock components to the action of smal...
The eye is a very important organ in the human body which is affected by various external factors. One of these factors is the sunlight which can cause the visual impairment and as well as the increase in the oxidative stress. The heme oxygenase I (HO-1) plays a very important role in the fight against the oxidative stress. The HO enzyme catalyses...
The tissue organization field theory (TOFT) presented completely new, different from the previous one, perspective of research on neoplasm processes. It implicates that secretory neuroepithelial-like cells (NECs), putative chemoreceptors, are probably responsible for the control of squamous epithelial cells proliferation in digestive tract during h...
The novel cancer theory named ‘the tissue organization field theory’ (TOFT) suggests that carcinogenesis is a process analogous to embryonic development, whereby organs are formed through interactions among different cell types. The suggested ‘morphological remodelling’ of the epithelium under hypoxia in gut breathing fish (GBF) has many common fea...
The purpose of the experiment was to obtain a response whether the electromagnetic field at the frequency of 50 Hz and magnetic induction of 2.5 mT affect the viability, proliferation and ability to migrate of MCF-7 cell line(the human breast adenocarcinoma cells) The viability of cells was assessed by trypan blue staining. The degree of cells prol...
