Immune cell counts and signaling in body fluids of cows vaccinated against Clostridium difficile
Journal of Biological Research-Thessaloniki - Tập 25 - Trang 1-22 - 2018
New treatment options are needed to prevent relapses following failed antibiotic therapies of Clostridium difficile infections (CDI) in humans. The concomitant therapy with an anti-C. difficile IgA containing whey protein concentrate can support the sustainable recovery of CDI patients. For 31 weeks, nine dairy cows were continuously vaccinated with several anti-C. difficile vaccines by certain ro......
Long‐term monitoring of common spadefoot toad activity in a European steppe using barn owl pelletsAbstract Background One third of the worldwide amphibian species are threatened, therefore, efficient monitoring efforts are needed. Amphibians which adopt a hidden lifestyle, such as the common spadefoot toad, are often missed with standard surveying efforts. Spadefoot toads can be identified in regurgitated pellets of the barn owl...

Polymorphism of the melatonin receptor 1A (MNTR1A) gene and association with seasonality of reproductive activity in a local Greek sheep breed
Journal of Biological Research-Thessaloniki - Tập 23 - Trang 1-4 - 2016
Sheep’s reproductive physiology in temperate latitudes (such as Greece), is characterized by seasonality and is also regulated by photoperiodic exposure. Melatonin is the key hormone involved in this regulation. However, the melatonin secretion and therefore the ewes reproductive activity underlies variation, proposed to be linked with the melatonin receptor subtype 1A (MNTR1A) gene structure. Thi......
Different solutions lead to similar life history traits across the great divides of the amniote tree of life
Journal of Biological Research-Thessaloniki - Tập 28 - Trang 1-17 - 2021
Amniote vertebrates share a suite of extra-embryonic membranes that distinguish them from anamniotes. Other than that, however, their reproductive characteristics could not be more different. They differ in basic ectothermic vs endothermic physiology, in that two clades evolved powered flight, and one clade evolved a protective shell. In terms of reproductive strategies, some produce eggs and othe......
Gram-negative and -positive bacteria differentiation in blood culture samples by headspace volatile compound analysis
Journal of Biological Research-Thessaloniki - Tập 23 - Trang 1-8 - 2016
Identification of microorganisms in positive blood cultures still relies on standard techniques such as Gram staining followed by culturing with definite microorganism identification. Alternatively, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry or the analysis of headspace volatile compound (VC) composition produced by cultures can help to differentiate between micro......
Campbell biology (edited by Lisa Urry, Michael Cain, Steven Wasserman, Peter Minorsky and Jane Reece)
Journal of Biological Research-Thessaloniki - Tập 27 - Trang 1-3 - 2020
Campbell Biology is divided into eight units and 56 chapters. The organization and size of this book are appropriate and easy for first-year university students and help them to learn and digest the content. Campbell Biology is currently among the best biology books and it is listed with the best shelling textbooks. Campbell Biology is mainly for first-year university students, but it is also an i......
Unbiased phenotypic identification of functionally distinct hematopoietic progenitors
Journal of Biological Research-Thessaloniki - Tập 26 - Trang 1-5 - 2019
Hematopoiesis is a model-system for studying cellular development and differentiation. Phenotypic and functional characterization of hematopoietic progenitors has significantly aided our understanding of the mechanisms that govern fate choice, lineage specification and maturity. Methods for progenitor isolation have historically relied on complex flow-cytometric strategies based on nested, arbitra......
Comparative transcriptional analysis of flavour-biosynthetic genes of a native Saccharomyces cerevisiae strain fermenting in its natural must environment, vs. a commercial strain and correlation of the genes’ activities with the produced flavour compounds
Journal of Biological Research-Thessaloniki - Tập 26 - Trang 1-14 - 2019
During alcoholic fermentation, Saccharomyces cerevisiae synthesizes more than 400 different compounds with higher alcohols, acetate esters of higher alcohols and ethyl esters of medium-chain fatty acids being the most important products of its metabolism, determining the particular flavour profile of each wine. The concentration of the metabolites produced depends to a large extent on the strain u......
Paralia (Bacillariophyta) stowaways in ship ballast: implications for biogeography and diversity of the genus
Journal of Biological Research-Thessaloniki - Tập 22 - Trang 1-26 - 2015
The genus Paralia Heiberg is one of the most recognizable, widely distributed and commonly reported diatoms from contemporary coastal marine environments and ship ballast. Species discovery has historically been made in diatoms through the recognition of morphological discontinuities between specimens, first using light and later electron microscopy. However, recently, morphologically semi-cryptic......
