Quantitative comparison of different purification and detection methods for Cryptosporidium parvum oocysts
(Elsevier Science Bv, 2011)Cryptosporidium parvum (C. parvum) is the causal agent of cryptosporidiosis in many animals, mainly cattle, and possesses a high zoonotic potential. It occurs worldwide and ubiquitously. Detection of C. parvum is mainly ... -
Ticks on humans in Ankara, Turkey
(Springer, 2011)In this study, a total of 5,094 ticks found on humans were examined in terms of species, development stage, gender, host features and seasonality for a year period. Of these ticks 17 were argasid and 5,077 were ixodid. ... -
High Prevalence of TSHR/Gs alpha Mutation-negative Clonal Hot Thyroid Nodules (HNs) in a Turkish Cohort
(Georg Thieme Verlag Kg, 2011)Whereas the majority of hot thyroid nodules are caused by somatic TSH-receptor mutations, the percentage of TSH-receptor mutation negative clonal hot nodules (HN) and thus the percentage of hot nodules likely caused by ... -
Bistability Analysis of an Apoptosis Model in the Presence of Nitric Oxide
(Springer, 2011)Bistability in apoptosis, or programmed cell death, is crucial for the healthy functioning of multicellular organisms. The aim in this study is to show the presence of bistability in a mitochondria-dependent apoptosis model ... -
Cryptosporidium parvum oocyst viability and behaviour of the residual body during the excystation process
(Springer, 2011)This study was conducted as a comparative evaluation of time-dependent changes in the viability of purified Cryptosporidium parvum oocysts by means of different excystation methods. Oocyst samples were 2 weeks to 12 months ... -
A Novel Mutation in the MC2R Gene Causing Familial Glucocorticoid Deficiency Type 1
(Karger, 2011)Familial glucocorticoid deficiency (FGD) or hereditary unresponsiveness to adrenocorticotropin (ACTH) is an autosomal recessive disorder characterized by isolated glucocorticoid deficiency associated with normal mineralocorticoid ... -
Development of an impedimetric aflatoxin M1 biosensor based on a DNA probe and gold nanoparticles
(Elsevier Advanced Technology, 2011)The present work describes the construction and application of a new DNA biosensor for detection of aflatoxin M1. In order to immobilize a thiol-modified single stranded DNA (ss-HSDNA) probe that specifically bound aflatoxin ... -
A novel, ultra sensible biosensor built by layer-by-layer covalent attachment of a receptor for diagnosis of tumor growth
(Elsevier, 2011)In the presented research, a novel, ultra sensitive biosensor for the impedimetric detection of vascular endothelial growth factor (VEGF) is introduced. The human vascular endothelial growth factor receptor 1 (VEGF-R1, ... -
Beta-galactosidase Determination by an Electrochemical Biosensor Mediated with Ferrocene
(Informa Healthcare, 2011)In this paper, a new viewpoint on the activity determination of beta-galactosidase is reported. Glucose oxidase was directly immobilized on a glassy carbon electrode and mediated by ferrocene. The biosensor's performance ... -
A New Voltammetric Method for the Determination of Lercanidipine in Biological Samples
(Slovensko Kemijsko Drustvo, 2011)Electrochemical behavior and adsorption-diffusion properties of lercanidipine (LCN) on a glassy carbon electrode (GCE) were investigated in a mixture of ethanol-Britton Robinson buffer (BR) using voltammetric methods. From ... -
A new impedimetric biosensor utilizing VEGF receptor-1 (Flt-1): Early diagnosis of vascular endothelial growth factor in breast cancer
