Sex estimation using foramen magnum measurements, discriminant analyses and artificial neural networks on an eastern Turkish population sample.

Background: Although many studies have been conducted using the foramen magnum for sex estimation, recent findings have indicated that the discriminant and regression models obtained from the foramen magnum may not be reliable. Artificial Neural Networks, was used as a classification technique in sex estimation studies on some other bones, did not used in sex estimation studies on the foramen magnum until now. The aim of this study was sex estimation on an Eastern Turkish population sample using foramen magnum measurements, discriminant analyses and Artificial Neural Networks.

Sex estimation from the clavicle using 3D reconstruction, discriminant analyses, and neural networks in an Eastern Turkish population.

Sex estimation of skeletal remains is an important aspect of forensic anthropology. The clavicle is a bone with relatively high accuracy in sex determination. In this study, 7 clavicular parameters were obtained using the CT images and 3D reconstruction of 360 cases equally distributed as 180 males and 180 females.

Comparison of placental elasticity in normal and pre-eclamptic pregnant women by acoustic radiation force impulse elastosonography.

Aim: The aim of this research was to study and compare placental elasticity with acoustic radiation force impulse (ARFI) elastography in pre-eclamptic and normal pregnancies.

Methods: A total of 107 singleton pregnancies in the third trimester (38 healthy control subjects, 34 patients with gestational hypertension, and 35 pre-eclampsia patients) were included in the study. ARFI elastography was used to determine the placental elasticity in the three predetermined regions of the placenta (the fetal edge, maternal edge, and central part of the placenta).

Relationship of PCNA, C-erbB2 and CD44s expression with tumor grade and stage in urothelial carcinomas of the bladder.

In the present study, the intention was to reveal the relationship of histological grade and stage with c-erbB2, CD44s, and PCNA immunoreactivity in bladder urothelial carcinomas (UC). In our study, we evaluated 46 items of transurethral resection material of patients submitted by YYU Faculty of Medicine, Main Department of Pathology, with a mass revealed in their bladder after clinical and radiological studies at our laboratories and who were diagnosed with urothelial carcinomas. PCNA, c-erbB2, and CD44s were applied in an immunohistochemical manner comprised from nine low-malignant potential papillary urothelial neoplasia, 23 low-grade papillary urothelial carcinoma, and 14 high-grade papillary urothelial carcinoma.

Three-dimensional measurements of the nasal interdomal fat pad.

The interdomal fat pad (IFP) is an important structure related to tip deformity in rhinoplasty. This study aimed to evaluate the IFP by ultrasonography before surgery, and to demonstrate the existence of the IFP as a distinct anatomic structure in cadavers and patients. Three dimensions of the IFP were measured in 23 patients using ultrasound before rhinoplasty and in 10 cadavers using dissection.
