Reference point indentation (RPI) has emerged as a novel tool to measure material-level biomechanical properties in vivo. Human studies have been able to differentiate fracture versus non-fracture patients while a dog study has shown the technique can differentiate drug treatment effects. The goal of this study was to extend this technology to the in vivo measurement of rats, one of the most co...

Introduction: Studies with single photon emission computed tomography (SPECT) have revealed inconsistent changes of regional cerebral blood flow (rCBF) in schizophrenia. Some studies investigated the rCBF and its relationship with psychopathology, positive and negative symptoms in treated patients. However, there is a little information about the pattern of rCBF in recently untreated or never t...

AIM The aim was to provide a dosimetric comparison between IMRT and RapidArc treatment plans with RPI index with simultaneous comparison of the treatment delivery time. BACKGROUND IMRT and RapidArc provide highly conformal dose distribution with good sparing of normal tissues. However, a complex spatial dosimetry of IMRT and RapidArc plans hampers the evaluation and comparison between plans c...

Late blight has been the most devastating potato disease worldwide. The causal agent, Phytophthora infestans, is notorious for its capability to rapidly overcome host resistance. Changes in the expression pattern and the encoded protein sequences of effector genes in the pathogen are responsible for the loss of host resistance. Among numerous effector genes, the class of RXLR effector genes is ...

Background Retrograde peri-implantitis (RPI) is a rapidly progressing periapical infection that forms around the implant apex. It usually associated with sites adjacent to teeth apical lesions; previous endodontic failures, retained root fragments, etc. This study aimed incidence of RPI in history surgeries. Methods Patients treated for both apicoectomy and placement presenting University Michi...

The study was conducted to determine the plants preference by goats grazing at Central Darfur State, Sudan in 2016. The objective was to identify desirable plants that would assist in range rehabilitation. Five mature female goats were used to determine diet selection using the bite count technique. The total number of bites from each plant species was recorded and the selected diet and prefere...

PURPOSE To analyze the relationship between the central corneal thickness (CCT) and mid-peripheral corneal thickness (PCT) with the degree of myopia [axial length (AL) and spherical equivalent refractive error (SE)]. METHODS 175 right myopic eyes from 175 patients were divided according to the degree of SE: group #1 (n=76, <6.00 D), group #2 (n=72, between 6.00 and 12.00 D) and group #3 (n=27...
