introduction: determination of the canal working length with radiographs has many drawbacks. electronic apex locators have been developed to overcome some of these problems. recently, a newly designed apex locator called novapex has been introduced. all the studies conducted to determine the accuracy of novapex have been carried out in-vitro on extracted teeth. the aim of this in vivo study was...

linarin is a flavone glycoside in the plants flos chrysanthemi indici, buddleja officinalis, cirsium setosum, mentha arvensis and buddleja davidii, and has been reported to possess analgesic, antipyretic, anti-inflammatory and neuroprotective activities. in this paper, linarin was investigated for its ache inhibitory potential both in vitro and ex vivo. ellman’s colorimetric method was used for...

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

OBJECTIVES Ex vivo lung evaluation (ex vivo) has been developed as a useful method by which to assess lungs from donation-after-cardiac death (DCD) donors prior to transplant. However, the safety of the ex vivo circulation itself with respect to grafts has not been fully investigated. The aim of this study is to evaluate the effects of the ex vivo circuit using a swine lung transplant model. ...

BACKGROUND We investigated whether ex vivo mesothelial cells found in peritoneal dialysis (PD) effluents were representative of the in vivo epithelial-to-mesenchymal transition (EMT) in peritoneal membrane. METHODS Thirty-six male Sprague-Dawley rats were equally divided into three groups: Group C (control), no PD; Group D, infused with 4.25% Dianeal and Group P, infused with 4.25% Physioneal...
