Accuracy of 3-dimensional curvilinear measurements on digital models with intraoral scanners [PDF]

American Journal of Orthodontics and Dentofacial Orthopedics, 2017
Our objectives were to evaluate and compare the digital dental models generated from 2 commercial intraoral scanners with manual measurements when performing 3-dimensional surface measurements along a curved line (curvilinear).Dry mandibles (n = 61) with intact dentition were used.

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer

Molecular Oncology, EarlyView.
New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.

The impact of leukocyte‐associated RNA retention on platelet RNA‐based cancer detection

Molecular Oncology, EarlyView.
Platelets carry RNA signals that may help detect cancer, but platelet samples can also retain RNA from white blood cells. We found that this retained white blood cell signal did not significantly affect machine learning cancer classification, suggesting that the cancer‐related RNA signal in platelets is largely independent of leukocyte‐associated RNA ...

Accuracy of prostate volume measurements using transrectal multiplanar three‐dimensional sonography [PDF]

International Journal of Urology, 2005
Abstract  The aim of this study is to evaluate the accuracy of three‐dimensional (3D) ultrasound in comparison with conventional bidimensional (2D) sonography in prostatic calculations. The study was performed using a Kretztechnik Voluson 530D machine with a 7.5 MHz endocavitary transducer.
