OBJECTIVE To evaluate the accuracy of antenatal sonographic measurement of lower uterine segment (LUS) thickness in the prediction of risk of uterine rupture during a trial of labor (TOL) in women with a previous Cesarean section (CS). METHODS PubMed and EMBASE were searched to identify articles published on the subject of sonographic LUS measurement and occurrence of a uterine defect after d...

INTRODUCTION Retinal nerve fiber layer (RNFL) thinning, assessed by optical coherence tomography (OCT), has recently been reported in various dementias. METHODS We conducted a systematic review and meta-analysis to investigate the diagnostic utility of RNFL thickness measurement using OCT in dementia (including Alzheimer's disease [AD] and mild cognitive impairment [MCI]) compared with health...

We have measured the dielectric properties and thickness of thin semiconductor epitaxy layers by the reflection of THz radiation from the surface of a two-layered semiconductor wafer. When reflecting from two interfaces the electromagnetic pulse has a destructive interference at a specific wavelength dependent on the thickness of the outer layer and its dielectric function. Near that frequency ...

PURPOSE The aim of this study is to evaluate the efficacy of an ultrasonographic measurement of placental thickness and the correlation of a thick placenta with adverse perinatal outcome. METHODS Placental thickness was measured in single gravidas, 16 to 40 weeks of gestation, between 2005 and 2009. Placentas were considered to be thick if their measured thickness were above the 95th percenti...

The present study used 127 extracted teeth from people aged 16 to 90 years old. The aim of this research was to verify the reliability of the method using a single dental parameter based on the correlation of the radicular cementum thickness and the chronological age of the subject. The thickness was measured both on the lingual side and on the vestibular side of the tooth, at two different lev...

PURPOSE The purpose of this study was to obtain the description of the mandibular bone quality of male and female patients between 40-60 years old and their differences based on mandibular cortical bone thickness measured using Mental Index (MI). MATERIALS AND METHODS Forty digital panoramic radiographs, which consisted of twenty male and twenty female patients, 40-60 years old, were observed...

The production of barrier packaging materials, e.g., for food, by physical vapor deposition (PVD) of inorganic coatings such as aluminum on polymer substrates is an established and well understood functionalization technique today. In order to achieve a sufficient barrier against gases, a coating thickness of approximately 40 nm aluminum is necessary. This review provides a holistic overview of...

As blood thickness depends on the concentration of blood cells in the vessels, the measurement of the thickness of the choroidal blood (which can now be done accurately by our bio-haemo-photometric method) facilitates the study of the choroidal circulation. The present communication reports the results of applying this method to the study of glaucomatous eyes, especially those with chronic open...

deviations). This may be attributed to the accuracy to which corneal thickness can be read with the specular microscope. All three methods appeared to be equally precise from session to session (as indicated by the intercession standard deviations). On the other hand, the Mishima-Hedby attachment demonstrated a decreasing trend from session to session (as indicated by the analysis of variance r...
