Dentistry: Are Stem Cells The Future?, Tova Zemel

The Science Journal of the Lander College of Arts and Sciences

Stem cell research is currently advancing in every area of medicine. New information about regenerating stem cells is being uncovered on a daily basis. An area of stem cells that has not been focused on until recently is the use of dental stem cells. The objective of this paper is to elucidate the most current research about dental stem cells. Much of what is discussed in this paper has not been implemented yet, and is still in clinical trials. Dental stem cells are important because they could be an alternative way of treating caries, performing root canals, and other traumas …

Taiwanese Journal of Orthodontics

In Class II deep-bite malocclusions with growth potential, we could combine orthodontic treatment with orthopedic methods to achieve stable occlusion. The case was a 12-year-old male presented with Class II malocclusion, deep-bite, and low mandibular plane angle. In the stage I treatment, headgear was used to restrict the growth of maxilla. Bilateral Class III molar relationship was gained. After re-evaluation, stage II treatment was started from full mouth banding and bonding, with emphasis on leveling lower curve of Spee and intruding lower anterior teeth by placing reverse curve of Spee in the archwire and intrusive arch to solve the deep …

Long-Term Observation Of Orthodontic Management And Facial Growth On A Patient With Familial Cleidocranial Dysplasia, Chung-Yi Ho, Ellen Wen-Ching Ko, Cheng-Hui Lin

Taiwanese Journal of Orthodontics

The orthodontic management of patients with cleidocranial dysplasia (CCD) is challenging, which takes a long treatment duration and observation to follow the progress. The completion of treatment is usually not finished until growth completion. This case describes the long-term stage treatment of a 22-year-old female presented with familial CCD. The first stage orthodontic treatment was separated into two phases including surgical exposure of the anterior and posterior teeth, respectively. Extraction of the delayed exfoliated deciduous incisors and supernumerary teeth to clear the eruption path of the submerged permanent anterior teeth was started at her age of 8. The impacted anterior …

Taiwanese Journal of Orthodontics

A 21-year-old female with severe concave profile and prominent chin came for surgical-orthodontic consultation. The patient had missing of four premolars which became intricate with extremely lingual inclined incisors and over-developed mandible. The surgery first approach (SFA) was adopted to correct the skeletal factors at the early stage. The pre-adjusted orthodontic bracket system was applied to normalize the torque of the teeth afterward. The capacities of anterior root-torquing auxiliary wire (ART) and multiple-loop edgewise archwire (MEAW) will be discussed, accordingly. The progress records showed remarkable improvement of profile and occlusion. The change of upper incisor show was also discussed. The …

Chulalongkorn University Dental Journal

To compare fracture resistance of endodontically treated maxillary premolars restored with ceramic restorations using three retentive techniques. Forty maxillary premolars were randomly selected as a control (Group 1), composite core/crown (Group 2), fiber-reinforced composite post/ composite core/crown (Group 3) and endocrown (Group 4). All restorations were thermo-cycled and subjected to vertical loading. Fracture load and fracture modes were analyzed. The results showed that Group 3 recorded a significantly highest fracture load (2304 ± 737 N). Pairwise comparisons showed no significant difference between Group 2 (1229 ± 303 N) and group 4 (1609 ± 395 N). Type of coronal-radicular retention was …

Animal Remains Of Alaybeyi Höyük, Abu Bakar Siddiq

Turkish Journal of Veterinary & Animal Sciences

This paper presents the zooarchaeological observations on animal remains of Alaybeyi Höyük unearthed from 2016 and 2017 excavation sessions. Dated to 4721-4553 cal. BC, Alaybeyi stands so far as the oldest archaeological settlement discovered in northeast Anatolia. Therefore, the faunal assemblage at Alaybeyi offers great opportunity to study the status of animals and their relationships with humans in the largely unexplored Kars-Erzurum plateau covering a period from the Chalcolithic to Late Iron Age. Taxonomic and osteometric analyses show that, like the present day, cattle were dominant over caprines, revealing extensive cattle pastoralism in the region for at least about 7 …

Phenotypic Characterization And Differentiation Of Mesenchymal Stem Cells Originating From Adipose Tissue, Ece Çerçi̇, Hati̇ce Erdost

Turkish Journal of Veterinary & Animal Sciences

Stem cells are known as undifferentiated cells that are capable of divisions and self-renewal over an extended period. Adipose tissue-derived mesenchymal stem cells (ADSCs) are known to differentiate into many different organ and tissue cells. The purpose of this study was to characterize adipose tissue-derived mesenchymal stem cells in detail based on the expression status of certain surface markers and differentiation stages for clinical and laboratory applications. The migrating phase and mitotic property of the cells from adipose tissue were assessed under a microscope. Cell counting was performed during the first, second, and third passages. The cells were differentiated into …

A Nasopharyngeal Inflammatory Polyp In A Cat: Histopathology, Immunohistochemistry, And Ct Scan Findings, Hamid Reza Moosavian, Hamideh Esmaeilzadeh, Ramesh Vahabi, Rana Vafaei, Mohammad Reza Esmailinejad

Turkish Journal of Veterinary & Animal Sciences

The etiology of feline nasopharyngeal inflammatory polyps (FNIPs) has not been completely understood. To the best of our knowledge, there is no study having evaluated the immunohistochemical features of FNIPs. More studies about the histopathological characteristics of such lesions can play a pivotal role in further understanding the disease. We present the clinical manifestations, computed tomography (CT) scan, histopathology, and immunohistochemistry features of a FNIP in a 7-year-old male neutered domestic shorthair cat. CT scan examination showed nasopharyngeal space occupation with some parts of destruction in nasal cavity. Immunohistochemical study of the sections demonstrated the presence of CD3$^{+}$ lymphocytes, and …

Specimens of Oreochromis niloticus (One control and 3 experimental groups) were fed diets mixed with different doses of mercury (control group = free of mercury; group 1 = 500 mg/kg; group 2 = 750 mg/kg, and group 3 = 1000 mg/kg) for 60 days in order to study its accumulation and histopathological alterations in the liver, gills, skeletal muscles, and skin. The results obtained revealed that mercury accumulation was significantly (P < 0.05) high in the liver and gills compared to the muscles and skin. The order of accumulation in these organs revealed to be liver > gills > muscles > skin. The fish fed various doses of mercury also showed histological alterations in these organs. Epithelial lifting and epithelial hypertrophy were seen in the gills of the …

Design Of An Osce To Assess Clinical Competence Of Occupational Therapy Students, Nancy E. Krusen, Debra Rollins

Journal of Occupational Therapy Education

Objective structured clinical examinations (OSCEs) are a series of controlled, timed stations in which students demonstrate clinical skills. OSCEs are commonly used within health professions education to demonstrate competence, prepare for clinical education, and conduct program evaluation. The body of literature addressing the use of OSCEs in occupational therapy (OT) is growing; however, there are no available guidelines for developing an OSCE specific to the profession. The purpose of this paper is to describe the design of an OSCE for OT students prior to fieldwork placement. Twelve OT practitioners participated in a modified-Delphi method to generate possible OSCE scenarios. The …

An Oasis In The Hospital Desert – General Aviation Meets Medicine, Ariel Braverman

International Journal of Aviation, Aeronautics, and Aerospace

Use of General Aviation and to support medical services is not novel. However, this paper is an attempt to establish a concept of a framework of using aviation, especially relatively low-operational cost fixed-wing aircraft as a convenient high-speed transport to bring medical staff to the rural and remote areas. Operating flight network will also be more efficient from the financial point of view - better than attracting medical personnel with high salaries. Existing regional and local airport system can be a feasible basis for airport-based medical network. This article is just an initial one and additional work needs to evaluate …
