Estimation of fatigue crack growth retardation due to crack branching
(2004)Quantitative analysis is provided to estimate the reduction of fatigue crack growth rate due to overload crack branching. A recent mixed-mode fatigue crack growth model based on the dilatational component of the accumulated ... -
Excision of an oxidative DNA lesion (8-oxo-deoxyguanosine) in Mytilus edulis populations from two sites in the eastern Irish Sea
(2008)Mussels (Mytilus edulis) from the urban/industrialised site of New Brighton, Merseyside, UK and the reference site of Llandudno, North Wales, UK were collected at various time-points in 2005-2006. The excision capacity of ... -
Gain-of-function variant in GLUD2 glutamate dehydrogenase modifies Parkinson's disease onset
(2010)Parkinson's disease (PD), a common neurodegenerative disorder characterized by progressive loss of dopaminergic neurons and their terminations in the basal ganglia, is thought to be related to genetic and environmental ... -
Growth Retardation, Reduced Invasiveness, and Impaired Colistin-Mediated Cell Death Associated with Colistin Resistance Development in Acinetobacter baumannii
(2014)Two colistin-susceptible/colistin-resistant (Col(s)/Col(r)) pairs of Acinetobacter baumannii strains assigned to international clone 2, which is prevalent worldwide, were sequentially recovered from two patients after ... -
Hemodialysis procedure does not affect the levels of sICAM-1 and sVCAM-1 in patients with end stage renal disease
(2005)Atherosclerosis is by far the leading cause of mortality and morbidity in patients with end stage renal disease undergoing chronic hemodialysis (HD). Vascular endothelial cell adhesion molecules like the intercellular ... -
hTERT regulation by NF-kappa B and c-myc in irradiated HER2-positive breast cancer cells
(2011)Purpose: Telomerase activity (TA), frequently observed in cancer, compensates for telomere shortening thus preventing cell senescence and conferring resistance to therapy. In the present study, we investigated the expression ... -
Increased levels of oxidative DNA damage in pesticide sprayers in Thessaly Region (Greece). Implications of pesticide exposure
(2014)The widespread use of pesticides substances nowadays largely guarantees the protection of crops and people from undesired pests. However, exposure to pesticides was related to a variety of human health effects. The present ... -
Influence of Potent Antioxidant Leguminosae Family Plant Extracts on Growth and Antioxidant Defense System of Hep2 Cancer Cell Line
(2010)Legumes are considered to be a very good source of polyphenolic compounds that may act as chemopreventive agents, especially by their antioxidant properties. However, many of the chemopreventive properties may depend on ... -
Insecticide resistance status of Myzus persicae (Hemiptera : Aphididae) populations from peach and tobacco in mainland Greece
(2007)The susceptibility of 88 and 38 field samples of Myzus persicae (Sulzer) to imidacloprid and deltamethrin respectively was examined using the FAO dip test bioassay. The field samples were collected from tobacco and peach ... -
Insecticide resistance status of the codling moth Cydia pomonella (Lepidoptera: Tortricidae) from Greece
(2011)The codling moth Cydia pomonella L is controlled mostly with chemical insecticides in Greece and control failures have been reported. However, there are no insecticide resistance studies in the country as yet. We examined ... -
Long-term exposure to muscarinic agonists decreases expression of contractile proteins and responsiveness of rabbit tracheal smooth muscle cells
(2014)Background: Chronic airway diseases, like asthma or COPD, are characterized by excessive acetylcholine release and airway remodeling. The aim of this study was to investigate the long-term effect of muscarinic agonists on ... -
A mathematical model of HIV dynamics in the presence of a rescuing virus with replication deficiency
(2011)Recently, an enzyme (Cre recombinase) has been developed by directed evolution that successfully removes the HIV genome from the nuclear DNA of infected cells. To explore this idea further, we hypothesized that a replication ... -
Molecular analysis of transferrin receptor mRNA expression in acute myeloid leukaemia
(2001)Transferrin receptor (TfR, CD71) is an integral membrane glycoprotein that mediates cellular uptake of iron. In most tissues, TfR expression is correlated positively with proliferation and regulated at the post-transcriptional ... -
Molecular cloning and sequence of gilthead sea bream (Sparus aurata) alpha-skeletal actin: tissue and developmental expression
(2001)In the present study, the Sparus aurata alpha -skeletal actin was cloned from a mixed larvae complementary DNA library. The clone isolated was 1523 bp long with an open reading frame of 1134 bp coding for a 377-amino acid ... -
A Multimethod Examination of the Relationship Between Coaching Behavior and Athletes' Inherent Self-Talk
(2010)The aim of the present research was to investigate the relationship between coaching behavior and athletes' inherent self-talk (ST). Three studies were conducted. The first study tested the construct validity of the Coaching ... -
Osseointegration of Osseotite (R) and machined-surfaced titanium implants in membrane-covered critical-sized defects: a histologic and histometric study in dogs
(2007)The texture of an implant's surface can influence the rate and extent of bone fixation as expressed by the amount of linear bone-to-implant contact (BIC). The purpose of this study was to compare the bone density and linear ... -
Predominantly post-transcriptional regulation of activation molecules in chronic lymphocytic leukemia: The case of transferrin receptors
(2008)Transcriptional and post-transcriptional control mechanisms have a differential impact on cellular physiology depending on activation status. Several lines of evidence suggest that chronic lymphocytic leukemia (CLL) malignant ... -
Ranolazine enhances nicardipine-induced relaxation of alpha1-adrenoceptor-mediated contraction on isolated rabbit aorta
(2015)Ranolazine (RAN) and nicardipine (NIC) have been studied for their vasorelaxing effects but the combination of these agents against adrenergic vasoconstriction has not been tested. The present study aimed at investigating ... -
Ranolazine Enhances the Antiarrhythmic Activity of Amiodarone by Accelerating Conversion of New-Onset Atrial Fibrillation After Cardiac Surgery
(2014)Ranolazine is a relatively novel antiischemic/antianginal compound with antiarrhythmic properties. We investigated its ability to shorten the time to conversion of postoperative atrial fibrillation (POAF) when added to ...
