Associations of Estrogen Receptor Alpha and Beta Gene Polymorphisms with Sex Steroid Levels and Body Fat Content in Men

Sakka, C.; Efstathiadou, Z. A.; Polyzos, S. A.; Goutou, M.; Stakias, N.; Koukoulis, G. N. (2012)

Objective: Estrogens play an important role in male physiology. We investigated the possible association of four single nucleotide polymorphisms in Estrogen Receptor alpha (ESR1) and Estrogen Receptor beta (ESR2) genes ...

Bisphosphonate use and risk of colorectal cancer: a systematic review and meta-analysis

Bonovas, S.; Nikolopoulos, G.; Bagos, P. (2013)

AimA growing body of evidence suggests that bisphosphonates may have chemopreventive potential against colorectal cancer. Our aim was to examine this association through a meta-analysis of observational studies. MethodsA ...

Cellular-automata and individual-based approaches for the modeling of biofilm structures: Pros and cons

Laspidou, C. S.; Kungolos, A.; Samaras, P. (2010)

Fresh water shortage is one of the greatest problems of modern society; as a result, water desalination, particularly with membrane processes, is becoming increasingly important, since it makes possible the use of brackish ...

Distribution and migration of insects and mites in flat storage containing wheat

Athanassiou, C. G.; Palyvos, N. E.; Eliopoulos, P. A.; Papadoulis, G. T. (2001)

Studies were conducted in a flat storeroom in central Greece, filled with approx., 90 tons of wheat, in order to evaluate insect and mite species abundance, and changes in population density and distribution among sampling ...

Elemental composition of bone minerals in women with breast cancer treated with adjuvant tamoxifen

KalefEzra, J. A.; Pavlidis, N.; Klouvas, G.; Karantanas, A.; Hatzikonstantinou, I.; Glaros, D. (1996)

Oestrogen levels play a major role in conditioning the rates of bone changes in women. Tamoxifen is a synthetic oestrogen antagonist commonly used as an adjuvant therapy for breast cancer. The goal of the present study was ...

Expression profile of osteoprotegerin, RANK and RANKL genes in the femoral head of patients with avascular necrosis

Samara, S.; Dailiana, Z.; Chassanidis, C.; Koromila, T.; Papatheodorou, L.; Malizos, K. N.; Kollia, P. (2014)

Introduction: Femoral head avascular necrosis (AVN) is a recalcitrant disease of the hip that leads to joint destruction. Osteoprotegerin (OPG), Receptor Activator of Nuclear Factor kappa-B (RANK) and RANK ligand (RANKL) ...

Material modeling of biofilm mechanical properties

Laspidou, C. S.; Spyrou, L. A.; Aravas, N.; Rittmann, B. E. (2014)

A biofilm material model and a procedure for numerical integration are developed in this article. They enable calculation of a composite Young's modulus that varies in the biofilm and evolves with deformation. The ...

Paraoxonase 1 gene polymorphisms in patients with osteonecrosis of the femoral head with and without cerebral white matter lesions

Hadjigeorgiou, G. M.; Malizos, K.; Dardiotis, E.; Aggelakis, K.; Dardioti, M.; Zibis, A.; Dimitroulias, A.; Scarmeas, N.; Tsezou, A.; Karantanas, A. (2007)

Cerebral white matter lesions (WML) are present in more than 50% of patients with osteonecrosis of the femoral head (ONFH). Paraoxonase 1(PON1) gene product is a detoxifying and pesticide metabolizing enzyme. Genetic ...

Plasma Serotonin and Markers of Bone Formation and Bone Resorption in Hemodialysis Patients
