Human Remains Identification Using Micro-CT, Chemometric and AI Methods in Forensic Experimental Reconstruction of Dental Patterns after Concentrated Sulphuric Acid Significant Impact.

(1) Teeth, in humans, represent the most resilient tissues. However, exposure to concentrated acids might lead to their dissolving, thus making human identification difficult. Teeth often contain dental restorations from materials that are even more resilient to acid impact.

Use of Advanced Artificial Intelligence in Forensic Medicine, Forensic Anthropology and Clinical Anatomy.

Three-dimensional convolutional neural networks (3D CNN) of artificial intelligence (AI) are potent in image processing and recognition using deep learning to perform generative and descriptive tasks. Compared to its predecessor, the advantage of CNN is that it automatically detects the important features without any human supervision. 3D CNN is used to extract features in three dimensions where input is a 3D volume or a sequence of 2D pictures, e.

Disc degeneration on MRI is more prevalent in young elite skiers compared to controls.

Purpose: Evidence-based facts regarding spine abnormalities and back pain are needed in order to develop rehabilitation programs and prevent spine injuries in young skiers. The aim therefore is to identify MRI changes in the thoraco-lumbar spine and the lifetime prevalence of back pain, as well as the association between them, in young skiers compared to non-athletes.

Methods: Seventy-five young elite alpine and mogul skiers, age range 16-20 years, were compared with 27 non-athletic controls.

Long-term quality assurance of [(18)F]-fluorodeoxyglucose (FDG) manufacturing.

Nine years of experience with 2286 commercial synthesis allowed us to deliver comprehensive information on the quality of (18)F-FDG production. Semi-automated FDG production line using Cyclone 18/9 machine (IBA Belgium), TRACERLab MXFDG synthesiser (GE Health, USA) using alkalic hydrolysis, grade "A" isolator with dispensing robotic unit (Tema Sinergie, Italy), and automatic control system under GAMP5 (minus2, Slovakia) was assessed by TQM tools as highly reliable aseptic production line, fully compliant with Good Manufacturing Practice and just-in-time delivery of FDG radiopharmaceutical. Fluoride-18 is received in steady yield and of very high radioactive purity.

Imaging and analysis of thin structures using positron emission tomography: Thin phantoms and in vivo tobacco leaves study.

In this work, a novel approach utilizing the designed phantoms imitating the plant tissues was applied for the evaluation of the relationships between the parameters of the prepared phantoms and/or quantitative variables obtained within the PET analysis. The microPET system developed for animal objects and approaches used made it possible to obtain the quantitative data in the form of (18)F radioactivity as well as the glucose (in µg) accumulated in leaf tissues within the dynamic in vivo study.

THORACIC SPINE IMAGING: A COMPARISON BETWEEN RADIOGRAPHY AND TOMOSYNTHESIS USING VISUAL GRADING CHARACTERISTICS.

The aim of the present study was to evaluate digital tomosynthesis (DTS) in thoracic spine imaging, comparing the reproduction of anatomical structures with that achieved using digital radiography (DR). In a prospective visual grading study, 23 patients referred in 2014 for elective radiographic examination of the thoracic spine were examined using lateral DR and DTS. The DR image and the DTS section images were read in random order by four radiologists, evaluating the ability of the modalities to present a clear reproduction of nine specific relevant structures of the thoracic vertebrae 3, 6 and 9 (T3, T6 and T9).

Comparison of radiological spino-pelvic sagittal parameters in skiers and non-athletes.

Background: The purpose of the present study is to compare the radiological parameters of the spino-pelvic sagittal alignment in young elite skiers and non-athletes of a similar age.

Methods: The sample group (n = 102) consisted of elite Alpine and Mogul skiers (n = 75) and a non-athletic population (n = 27), mean age for both groups was 17.7 (±1.

The quantified evaluation of the wounding potential of a ricochet projectile of a handgun cartridge calibre 9 mm (type 82) in a ballistic experiment.

Unlabelled: The question of handgun use in a city or densely populated aglomerations requires a highly practical level of solution to this issue, though with the knowledge of theoretical presumptions of wound ballistics of ricochet projectiles. The application of wound ballistics into the practice of a forensic pathologist, as well as a surgeon or a traumatologist, enables a good understanding of the dynamics of projectile penetration through anatomic structures of the human body. In forensic assessment, gunshot wounds of limbs are relatively frequent cases.

Expression of constitutive nitric oxide synthase isoforms in varicose vein wall; preliminary results.

There are conflicting findings in literature about the structural changes of the primary varicose veins. NO (a potent vasodilatator) is synthesized by nitric oxide synthase (NOS). From 3 known NOS isoforms the two are constitutional: eNOS (endothelial NOS) and nNOS (neuronal NOS).

Fatal case of Rapunzel syndrome in neglected child.

Rapunzel syndrome is very extreme form of trichobezoar formation where the tail of the trichobezoar extends from the stomach into the small intestine. Death resulting from this condition is rare and is usually associated with gastric or intestinal perforation. We report a fatal case of Rapunzel syndrome in a 3 years and 10 months old girl.

Mast cell infiltration in the wall of varicose veins.

Varicose veins of the lower extremities are abnormally dilated, tortuous and elongated. The exact cause of vein dilatation has still not been established. Mast cells produce, store and release various types of vasoactive compounds (histamine, tryptase, prostaglandins, leukotrienes, and cytokines).
