microTSS: Accurate microRNA transcription start site identification reveals a significant number of divergent pri-miRNAs
(2014)A large fraction of microRNAs (miRNAs) are derived from intergenic non-coding loci and the identification of their promoters remains 'elusive'. Here, we present microTSS, a machine-learning algorithm that provides highly ... -
NAP: The Network Analysis Profiler, a web tool for easier topological analysis and comparison of medium-scale biological networks
(2017)Objective: Nowadays, due to the technological advances of high-throughput techniques, Systems Biology has seen a tremendous growth of data generation. With network analysis, looking at biological systems at a higher level ... -
NAT/NCS2-hound: a webserver for the detection and evolutionary classification of prokaryotic and eukaryotic nucleobase-cation symporters of the NAT/NCS2 family
(2018)Nucleobase transporters are important for supplying the cell with purines and/or pyrimidines, for controlling the intracellular pool of nucleotides, and for obtaining exogenous nitrogen/carbon sources for metabolism. ... -
Patterns of 1,748 Unique Human Alloimmune Responses Seen by Simple Machine Learning Algorithms
(2020)Allele specific antibody response against the polymorphic system of HLA is the allogeneic response marker determining the immunological risk for graft acceptance before and after organ transplantation and therefore routinely ... -
The perceptions of athenian physiotherapists on the referral service in Greece and its impact on professional autonomy
(2010)Background and Purpose. The attainment of professional autonomy is considered a priority of any profession. The development of autonomy in physiotherapy has differed among countries, with some achieving a high degree of ... -
Phenotypes of comorbidity in OSAS patients: Combining categorical principal component analysis with cluster analysis
(2016)Phenotyping obstructive sleep apnea syndrome's comorbidity has been attempted for the first time only recently. The aim of our study was to determine phenotypes of comorbidity in obstructive sleep apnea syndrome patients ... -
Phylogeography of roe deer (Capreolus capreolus) populations: The effects of historical genetic subdivisions and recent nonequilibrium dynamics
(2004)We sequenced 704 mitochondrial DNA (mtDNA) control-region nucleotides and genotyped 11 autosomal microsatellites (STR) in 617 European roe deer (Capreolus capreolus) samples, aiming to infer the species' phylogeographical ... -
Pressurized liquid extraction of polyphenols and anthocyanins from saffron processing waste with aqueous organic acid solutions: Comparison with stirred-tank and ultrasound-assisted techniques
(2021)Follow up with our previous study on the extraction of saffron processing waste polyphe-nols using deep eutectic solvents, the objective of this examination was a comparative evaluation of pressurized liquid extraction ... -
Prevalence and determinants of current cigarette smoking and secondhand smoking among Greek adolescents: The Global Youth Tobacco Survey (GYTS) 2013 study
(2020)Objectives Smoking prevalence in Greece is considered high within the European Union and the collection of evidence on tobacco use among adolescents is of vital importance in order to develop effective smoking prevention ... -
Recording lifetime behavior and movement in an invertebrate model
(2011)Characterization of lifetime behavioral changes is essential for understanding aging and aging-related diseases. However, such studies are scarce partly due to the lack of efficient tools. Here we describe and provide proof ... -
Salinity tolerance evaluation of barley germplasm for marginal soil utilization
(2021)One greenhouse experiment was conducted to assess the tolerance to salinity and water deficit stresses of 184 barley varieties (breeding lines or registered varieties). Also, a 2-year field experiment was conducted to ... -
T-RECs: Rapid and large-scale detection of recombination events among different evolutionary lineages of viral genomes
(2017)Background: Many computational tools that detect recombination in viruses are not adapted for the ongoing genomic revolution. A computational tool is needed, that will rapidly scan hundreds/thousands of genomes or sequence ... -
Tracking the global dispersal of a cosmopolitan insect pest, the peach potato aphid
(2009)Background. Global commerce and human transportation are responsible for the range expansion of various insect pests such as the plant sucking aphids. High resolution DNA markers provide the opportunity to examine the ... -
Transient up- and down-regulation of expression of myosin light chain 2 and myostatin mRNA mark the changes from stratified hyperplasia to muscle fiber hypertrophy in larvae of gilthead sea bream (Sparus aurata L.)
(2016)Hyperplasia and hypertrophy are the two mechanisms by which muscle develops and grows. We study these two mechanisms, during the early development of white muscle in Sparus aurata, by means of histology and the expression ... -
An Updated Review of Meat Authenticity Methods and Applications
(2016)Adulteration of foods is a serious economic problem concerning most foodstuffs, and in particular meat products. Since high-priced meat demand premium prices, producers of meat-based products might be tempted to blend these ... -
The use of various statistical methods for authenticity and detection of adulteration in fish and seafood
(2022)Various methodologies including genetic analyses, morphometrics, proteomics, lipidomics, metabolomics, etc. are now used or being developed to authenticate fish and seafood. Such techniques usually lead to the generation ... -
Who cares about the environment?
(2018)Environmental behavior substantially differs among individuals depending on their environmental attitudes, connectivity to nature beliefs, and socioeconomic profile. People who adopt an eco-friendly lifestyle and those who ...
