Comparative study of teacher trainees studying in 2 year and 4 year integrated B.Ed. Programme.

Abstract Teachers play a vital role in student’s life. They act as mentors, friend, philosophers and guide. If the teachers have updated knowledge and understanding then they are the ones who can bring positive changes in the society. With regard to this the researcher chooses few areas which are necessary to be thorough, for the teacher trainees. Hence the researcher develops selfconstructed tool to access the level of knowledge gained in the areas of ICT, Emotional maturity, Interpersonal skills and awareness of acquisition of Bloom’s taxonomy. The data is collected and analyzed using t-test

An Empirical study on Emotional Maturity among Teacher trainees and its Importance.

Abstract Emotional maturity is a process which guides oneself to successfully balance ones entire emotional spectrum and thereby taking responsibility as to how one feels about oneself and see the world around. Hence, it is essential for teacher trainees to show emotional balance when they deal with the students around them. This paper tries to investigate emotional maturity among 4 year integrated teacher trainees and 2 year B.Ed teacher trainees based on their duration of course and gender. The data was collected using self-constructed emotional maturity scale and data was analysed using SPSS (Statistical package for Social Sciences) software. The paper discusses the results and states its importance for teacher trainees

Role of Multidetector Computed Tomography in Evaluating Maxillofacial Injuries: A Comprehensive Study

Background: Maxillofacial trauma presents significant clinical challenges due to its impact on both physical appearance and mental well-being. Traditional imaging modalities, such as plain radiography, often fall short in providing detailed insights into complex facial fractures. This study aimed to evaluate the efficacy of multidetector computed tomography (CT) in the assessment of maxillofacial injuries, focusing on the benefits of 3D reconstructed images and comparing detection capabilities in axial and coronal planes. Methods: A total of 100 patients with a history of maxillofacial trauma and facial bone fractures were examined using multidetector CT. The data obtained were analyzed to assess the detection, extent, and displacement of various facial fractures across different imaging planes. Results: Multislice CT and 3D reconstructed images demonstrated superior capabilities in detecting and characterizing facial fractures compared to traditional axial and coronal CT scans. While 3D imaging excelled in detecting frontal and zygomatic bone fractures, axial and coronal scans were more effective in identifying fractures in the naso-orbito-ethmoid region and medial orbital wall. Conclusion: Multidetector CT, particularly when coupled with 3D reconstruction, offers a comprehensive and accurate imaging approach for evaluating maxillofacial injuries. Tailored imaging strategies, considering the specific injury location and complexity, are crucial for precise diagnosis and optimal treatment planning. DOI: https://doi.org/10.52710/seejph.49

Biomimetic strategies for fracture repair: engineering the cell microenvironment for directed tissue formation

Complications resulting from impaired fracture healing have major clinical implications on fracture management strategies. Novel concepts taken from developmental biology have driven research strategies towards the elaboration of regenerative approaches that can truly harness the complex cellular events involved in tissue formation and repair. Advances in polymer technology and a better understanding of naturally derived scaffolds have given rise to novel biomaterials with an increasing ability to recapitulate native tissue environments. This coupled with advances in the understanding of stem cell biology and technology has opened new avenues for regenerative strategies with true clinical translatability. These advances have provided the impetus to develop alternative approaches to enhance the fracture repair process. We provide an update on these advances, with a focus on the development of novel biomimetic approaches for bone regeneration and their translational potential

Objective assessment of progressive increase in bite force post surgical correction of mandibular fractures using Nupai bite scan analyser

Background: Fracture of mandible is a common condition which is increasing in incidence in the trauma centers due to increasing motor vehicles and failure to abide by traffic regulations. Patients undergo surgical open reduction and internal fixation where post-operative occlusion and normal masticatory functions are targeted. Bite force can be taken as a guide of normal masticatory function of an individual which is dependent upon craniomandibular biomechanics. The aim of the study was to analyse bite force measurements post-operatively in patients who underwent open reduction and internal fixation for mandible fractures at different sites.Methods: Molar bite force was recorded in 31 post-operative patients who underwent open surgical procedure for fracture mandible in the department of plastic surgery from January 2018 to June 2019 by a pre-scale bite force recorder-Nupai bite force prescale system (FujiTM). Various parameters were recorded pre and post-operatively including age, gender, history, comorbidities, requirement of MMF, site and number of fractures and age of injury. Bite force were compared and improvement of bite force every 2 weeks was noted and analyzed upto 6 weeks postoperatively.Results: Bite force improvement was seen in all types of mandible fractures irrespective of the site and type of fractures over a period of 6 weeks post-operatively. This improvement was however not statistically significant. Decreased time interval form injury to surgery resulted in improved bite force measurements though not statistically significant.Conclusions: Although objective improvement in bite force could be demonstrated but extensive study involving more subjects and more patient variables would have statistical significance

The Prrx1eGFP Mouse Labels the Periosteum During Development and a Subpopulation of Osteogenic Periosteal Cells in the Adult

The identity of the cells that form the periosteum during development is controversial with current dogma suggesting these are derived from a Sox9-positive progenitor. Herein, we characterize a newly created Prrx1eGFP reporter transgenic mouse line during limb formation and postnatally. Interestingly, in the embryo Prrx1eGFP-labeled cells become restricted around the Sox9-positive cartilage anlage without themselves becoming Sox9-positive. In the adult, the Prrx1eGFP transgene live labels a subpopulation of cells within the periosteum that are enriched at specific sites, and this population is diminished in aged mice. The green fluorescent protein (GFP)-labeled subpopulation can be isolated using fluorescence-activated cell sorting (FACS) and represents approximately 8% of all isolated periosteal cells. The GFP-labeled subpopulation is significantly more osteogenic than unlabeled, GFP-negative periosteal cells. In addition, the osteogenic and chondrogenic capacity of periosteal cells in vitro can be extended with the addition of fibroblast growth factor (FGF) to the expansion media. We provide evidence to suggest that osteoblasts contributing to cortical bone formation in the embryo originate from Prrx1eGFP-positive cells within the perichondrium, which possibly piggyback on invading vascular cells and secrete new bone matrix. In summary, the Prrx1eGFP mouse is a powerful tool to visualize and isolate periosteal cells and to quantify their properties in the embryo and adult. © 2022 The Authors.
