Over the second half of 20(th) century much research on lipogenesis has been conducted, especially focused increasing production efficiency and improving quality animal derived products. However, many diferences are observed in physiology between species. Recently, studies have also elucidated involvement numerous genes this procedure, highlighting not only at but molecular level. The main scope review is to point out major differences ruminant non species, that key regulatory involved...
Climate change is a contemporary global challenge that requires comprehensive solutions to mitigate its adverse effects. All human activities contribute climate change, mainly through atmospheric emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4). While most these are primarily due fossil fuel use, agriculture livestock production also significant share approximately 12% emissions. Most processes implemented within an animal husbandry...
The prognostic role of circulating tumor DNA (ctDNA)-based molecular residual disease (MRD) detection and its utility for postsurgical risk stratification has been reported in colorectal cancer. In this study, we explored the use ctDNA-based MRD patients with liver metastases (CLM), whom survival benefit adjuvant chemotherapy (ACT) after surgical resection remains unclear.
In recent years, welfare, which includes pleasurable and unpleasant emotions, is of utmost importance in animals reared under intensive farming systems. Various indices have been reported to evaluate welfare. Among them, vocalizations form non-invasive animals' inner state. The aim the study was determine whether changes ewes' raising group composition may alter differences their vocal characteristics. Forty two dairy sheep breeds (Chios Karagouniki) were used. experiment lasted for six...
This study aims to examine the genetic structure and diversity levels of seven indigenous Greek horse breeds: Andravida, Pindos, Thessaly, Skyros, Penia, Messara Rodos, using 15 microsatellites. Phenotypic traits were combined with factorial correspondence analyses create two datasets: one “Baseline” containing typical samples, “Unknown” non-typical or disputed origin samples. In horses, 142 alleles found. The mean observed effective number alleles, polymorphism information content allelic...

Different approaches (i.e., agronomic models, statistical regression equations linking thermal stress to output) were combined estimate from changes average values climatic parameters, subsequently economic this long-term change. Recorded damages events together with thresholds per event these...
Sheep's reproductive physiology in temperate latitudes (such as Greece), is characterized by seasonality and also regulated photoperiodic exposure. Melatonin the key hormone involved this regulation. However, melatonin secretion therefore ewes activity underlies variation, proposed to be linked with receptor subtype 1A (MNTR1A) gene structure. This study was designed investigate polymorphism of MNTR1A a local Greek sheep breed determine its potential association seasonality.Two groups farmed...
Abstract Background The indigenous cattle populations from Greece and Cyprus have decreased to small numbers are currently at risk of extinction due socio-economic reasons, geographic isolation crossbreeding with commercial breeds. This study represents the first comprehensive genome-wide analysis 10 continental Greek islands, one Cyprus, compares them 104 international breeds using more than 46,000 single nucleotide polymorphisms (SNPs). Results We estimated several parameters genetic...
Post-neoadjuvant therapy (post-NAT) and post-surgical circulating tumor DNA (ctDNA) risk stratification may enhance the management of patients with locally advanced rectal cancer (LARC). In this study, we assessed prognostic value ctDNA-based MRD detection in LARC using a personalized, tumor-informed ctDNA assay. Plasma samples from (N = 30) were analyzed retrospectively Signatera™ The neoadjuvant (NAR) score was calculated compared to status predict recurrence survival outcomes....
The aim of the present study was to determine any potential association BF, RBP4, and ESR2 genes with reproduction traits in an autochthonous Greek pig population. PCR-RFLP methodology implemented for genotyping purposes examined genes. No deviation from Hardy-Weinberg equilibrium observed loci, while B allele noted be more frequent all analyzed In addition, sows AA genotype BF gene found produce significantly lower numbers total born piglets (TNB) number alive (TNA), respective BB exceeded...
This e research focused on the detection and identification of genetic polymorphisms in exon 7 β-casein CSN2 gene blood samples from Greek Holstein cows local breeds cattle, such as Vrachykeratiki, Katerinis, Sykias. For this purpose, DNA was isolated 780 obtained cows, 86 three namely Brachyceros, Sykias, 14 buffalo. The desired region amplified by PCR, resulting 121 251 bp products bovine buffalo samples. PCR product digested with restriction fragment length polymorphism (RFLP) agarose...
PCR-RFLP was applied to a commercial crossbred pig population in order investigate the association between polymorphism (SNP) of Retinol-binding protein 4 (RBP4) gene and reproductive performance. 400 sows were genotyped 2000 records traits used retrieve information about allele frequencies RBP4 with main characteristics population. A deviation from Hardy-Weinberg equilibrium observed as result AB genotype excess. In addition, AA saw statistically significant higher values (i) total number...
Abstract Introduction The aim of this study was to determine changes reactive oxygen species (ROS), serum antioxidant capacity (SAC), oxidative stress index (OSi), and α -tocopherol ( -T) during the periparturient period in healthy mastitic cows further investigate whether these parameters can be used as a tool for identifying at higher risk developing mastitis. Material Methods Blood samples from 110 dairy two commercial farms were obtained dry-off, calving, 30 days post-partum. Healthy...
Although pig meat accounts for nearly half of total production in Europe, less attention has been focused on the greenhouse gas (GHG) emissions farming. The aim this study was to assess and compare impact livestock GHG during period 2015–2020 major European countries, including Greece, using different computational approaches (Tier 1, Tier 2, Gleam-i software v. 2.0 developed by FAO, Rome, Italy). A semi-extensive farm also used as a small-scale scenario. ranking countries related not...
The poultry sector is considered to be one of the most industrialized sectors livestock production. Although contributes 14.5% total anthropogenic greenhouse gas (GHG) emissions, less attention has been paid in respective emissions compared other farmed animals such as ruminants. aim study was estimate carbon footprint (layers, broilers, and backyards) Greek territory during last 60 years a means exploring further mitigation strategies. Tier 2 methodology used GHG emissions. Different...

Abstract Most ungulate mammals are social species that live in large groups where agonistic encounters with con‐specifics common. Such interactions may be a source of distress and can pose threat to group's cohesion. Group stability achieved by third‐party interventions, defined as the behavior individuals (interveners) interrupting between two through direct physical contact, interposition, or threats. This costly for intervener but lead benefits like reciprocity, group cohesion, enhance...
Toll-like receptors (TLRs) and b-defensins (BD) molecules are group of that recognize various microbial components play a crucial role in the activation innate immune system vertebrate species.
