Investigation of the Effect of Local and Systemic Preoperative Dexamethasone Application on Bone Tissue Healing in Mandibular Bone Defects.

Objectives: The aim of this study was to investigate the effect of locally and systemically delivered single-dose corticosteroid injections on bone tissue.

Study Design: A total of 84 Wistar albino rats were divided into 2 groups as local and systemic injection groups, and 2 groups as control and experiment among themselves. Before the procedure, dexamethasone was given to the experimental group and physiological saline was given to the control group.

Inflammation-associated long non-coding RNA signature in radicular cyst tissues.

Radicular cysts are characterized by significant levels of changes in inflammatory biomarkers. Among them, interleukins and growth factors have been reported to be deregulated in radicular cyst tissues. Moreover, long non-coding RNAs are recently discovered non-coding RNA molecules that regulate various intracellular stimuli to keep homeostasis in balance.

Expression pattern of hypoxia-related genes in odontogenic cysts.

Objective: The aim of the present study was to reveal the effects of hypoxia-associated signaling in odontogenic cysts.

Design: The expression levels of genes involved in the hypoxia-associated signaling pathway were determined by quantitative Polymerase Chain Reaction (PCR) method.

Results: As a result, it was found that phosphatase and tensin homolog (PTEN) expression was low (p = 0.

Land cover change detection in the Turkish coastal zone based on 28-year (1990-2018) Corine data.

In this research, land cover changes in the coastal region of Turkey were analyzed using the Corine dataset between 1990 and 2018. Changes in each period were analyzed by using the rate of change and the annual rate of change, the transition matrix of net changes, and the transition probability matrix. In order to predict land cover change trends and to determine future land cover change probabilities, a combination of Markov and cellular automata models was used.

Is the YouTube™ a useful resource of information about orthognathic surgery?: A cross-sectional study.

Purpose: YouTube™ has become a widely used resource of information about health-related topics nowadays. This cross-sectional study has aimed to analyze the content and quality of YouTube™ videos on orthognathic surgery.

Methods: In our study, six orthognathic surgery-related keywords (Le Fort I osteotomy, sagittal split osteotomy, jaw surgery, jaw correction surgery, orthodontic surgery, and orthognathic surgery) were used to search on YouTube™.

Summer season sea surface temperature changes in the Aegean Sea based on 30 years (1989-2019) of Landsat thermal infrared data.

In this research, sea surface temperature (SST) variability for the summer season in the Aegean Sea was analysed over a period of 30 years by using the Landsat thermal infrared bands. A total of 88 Landsat 5, 7, and 8 thermal infrared satellite images from June, July, and August were used for each year from 1989 to 2019. To estimate SST from the thermal infrared band data, thermal infrared sensor at-sensor spectral radiance, and thermal infrared sensor top-of-atmosphere brightness temperatures were used.
