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...

background: understanding the differences in genetics of malignancies is crucial for therapeutic decisions. this systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. material and methods: we performed a systematic review of the literature published on genetics of pediatrics bone tumors, using pubmed, google scholar, scie...

introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

Cryoprobes create localized cell destruction through freezing. Bone is resistant to temperature flow but is susceptible to freezing necrosis at warmer temperatures than tumor cells. Few studies have determined the thermal conductivity of human bone. No studies have examined conductivity as related to density. The study goal was to examine thermal conductivity in human bone while comparing diffe...

Pet owners desire treats with adequate nutritional profiles, functional benefits, long-lasting properties and an interactive nature. Therefore, it is pivotal to understand the digestion characteristics of treats produced by different processing methods and having variable nutritional composition. The objective of the present study was to measure in vitro disappearance characteristics of selecte...

Evidence is mounting that the temporal dynamics of the climate system are changing at the same time as the average global temperature is increasing due to multiple climate forcings. A large number of extreme weather events such as prolonged cold spells, heatwaves, droughts and floods have been recorded around the world in the past 10 years. Such changes in the temporal scaling behaviour of clim...

The infrapopulation size, or crowding, is an important measure in parasitology because of its impact on many facets of parasite biology. However, crowding values are difficult to handle statistically because of dependencies. Therefore, a bootstrap procedure was proposed in order to compare crowding between 2 groups or samples of hosts. Here, we propose Lepage's location-scale test based on inte...

Several single-molecule studies aim to reliably extract parameters characterizing molecular confinement or transient kinetic trapping from experimental observations. Pioneering works from single-particle tracking (SPT) in membrane diffusion studies [Kusumi et al., Biophys. J. 65, 2021 (1993)] appealed to mean square displacement (MSD) tools for extracting diffusivity and other parameters quanti...

Study sample Power calculations were performed in the preliminary phase of the study. These were based on a 58% success rate for the abdominal group, a 29% success rate for the vaginal group, a significance level of 5% and a statistical power of 80%. This led to a sample size of 40 women in each group, which was increased to 95 to minimise the impact of loss to follow-up (expected to be around ...

BACKGROUND Mental practice, the cognitive rehearsal of a task in the absence of overt physical movement, has been successfully used in teaching complex psychomotor tasks including sports and music, and recently, surgical skills. The objectives of this study were, 1) To develop and evaluate a mental practice protocol for mastoidectomy 2) To assess the immediate impact of mental practice on a mas...
