A Combination of Hand-held Models and Computer Imaging Programs Helps Students Answer Oral Questions about Molecular Structure and Function: A Controlled Investigation of Student Learning

We conducted a controlled investigation to examine whether a combination of computer imagery and tactile tools helps introductory cell biology laboratory undergraduate students better learn about protein structure/function relationships as compared with computer imagery alone. In all five laboratory sections, students used the molecular imaging program, Protein Explorer (PE). In the three experimental sections, three-dimensional physical models were made available to the students, in addition to PE. Student learning was assessed via oral and written research summaries and videotaped interviews. Differences between the experimental and control group students were not found in our typical course assessments such as research papers, but rather were revealed during one-on-one interviews with students at the end of the semester. A subset of students in the experimental group produced superior answers to some higher-order interview questions as compared with students in the control group. During the interview, students in both groups preferred to use either the hand-held models alone or in combination with the PE imaging program. Students typically did not use any tools when answering knowledge (lower-level thinking) questions, but when challenged with higher-level thinking questions, students in both the control and experimental groups elected to use the models.

Abstract BackgroundDue to numerous complications of an abnormal shape of the spine, it is extremely important to systematically monitor its shape. Precise and routine method of measurement enables comparison of the scores obtained over time and possible early intervention in order to avoid complications.The aim of the work is to present the pattern for monitoring changes in the shape of the spine in children with postural deformities.MethodsThe study group (n = 211) consisted of the patients with diagnosed shape of the spine deformity, who underwent a four-month therapy, supervised by a physiotherapist. The control group (n = 101) were the children with no shape of spine deformity.The children in the study group underwent a three-dimensional computer analysis of the shape of the spine. The DIERS test was performed in both groups (study and control). In the study group it was performed four times. It involved the measurement of seven parameters enabling a complete assessment of body posture.ResultsStatistically significant scores of the Friedman test for imbalance, pelvic tilt, kyphosis angle, lordosis angle, and lateral deviation were observed. Therefore, a series of post-hoc analyzes were performed using Dunn-Bonferroni tests. It was observed that changes in individual parameters analyzed in the authors' study come up at a different pace.ConclusionsDetailed monitoring of the parameters describing the position of the spine makes it possible to control the course of the treatment process of patients with disorders of the position of the spine. The dynamics of changes taking place within the spine position varies for the individual parameters analyzed.

ABSTRACT Objectives To examine the relationship between mandibular volume and craniofacial morphology in patients with cleft lip and palate using cone beam computed tomography (CBCT) and to compare these findings with control (noncleft) patients undergoing CBCT for other purposes during the deciduous dentition period. Materials and Methods Eighty-four patients were categorized into the unilateral cleft lip and alveolus (UCLA) group (n = 25; mean age, 4.60 ± 0.40 years), unilateral cleft lip and palate (UCLP) group (n = 23; mean age, 4.52 ± 0.39 years), bilateral cleft lip and palate (BCLP) group (n = 22; mean age, 4.54 ± 0.37 years), and control group without cleft (n = 14; mean age, 5.19 ± 0.52 years). Mandibular volume and craniofacial cephalometric measurements were obtained using CBCT. All measurements were assessed by analysis of covariance (ANCOVA) using Bonferroni post hoc pairwise comparison tests. Results ANCOVA revealed no statistically significant differences in mandibular volume among the groups. SNA° and ANB° were significantly larger in the UCLA and BCLP groups than in the control group. SN-MP° was smallest in the UCLA group. Co-A in the UCLP group was shorter than in the UCLA and BCLP groups. Go-Gn was shortest in the UCLP and BCLP groups compared with the control group. Conclusions Three-dimensional evaluation of craniofacial morphology using CBCT can provide valuable information on malocclusion and other dentoskeletal problems among patients with CLP.

Background Obesity is a chronic metabolic disorder associated with cardiovascular disease (CVD) increasing morbidity-mortality rates. It is apparent that a variety of adaptations/alterations in cardiac structure and function occurs as excessive adipose tissue accumulates. This leads to a decrease in diastolic compliance, eventually resulting in an increase in left ventricular filling pressure and left ventricular enlargement.Objective To evaluate left ventricular hypertrophy (LVH) among obese using electrocardiographic (ECG) criteria.Methods A cross-sectional study was conducted on 74 children aged 10-15 years from February 2009 to October 2009. The subjects were divided into obese and control groups. Physical examination and standard 12 lead electrocardiography (ECG) were done in both groups.Results Of 37 obese children, LVH were featured in 3 subjects, while in control group, only 1 child had LVH (P= 0.304). We found that mean RV6 in obese and control group were 9.8446 (SD 3.5854) and 11.9662 (SD 3.2857), respectively (P=0.005). As an additional findings, we found that birth weight was related to obesity in children.Conclusion There is no relation between obesity and left ventricular using ECG criteria in obese children aged 10-15 years.

Student activities and instructor-made models are described to facilitate and encourage other instructors to develop their own appropriate activities and models for teaching the three-dimensional structure of wood. The teaching activities include making several annual rings with straws pushed into clay, drawing wood’s structure onto a piece of paper that is folded to resemble a wedge, and assigning students to make an anatomical model to present in class. Plans are given for instructor-made models (1:500 scale) of tracheids, vessel elements, and a hardwood ‘fiber’ to demonstrate their relative dimensions and geometries. These models also include a set of outerwood and corewood tracheids onto which the microfibril angle is traced, and one tracheid on which bordered and cross-field pitting are shown. Plans are then given for a bordered pit pair with its membrane (1:6300 scale). The last model demonstrates the Hagen-Poiseuille equation with an array of 16 conduits that together have the same potential flow as one conduit of two times their diameter. The use of these models has enlivened the classroom and helped students to more readily grasp wood anatomy and function.

Abstract Background: Torsional malalignment has been considered as a risk factor for patella dislocation. But the influence of patella dislocation for torsional alignment development remains unknown. The present study aims to investigate whether the torsion alteration of the hindlimb occur after patella dislocation in growing rabbits. Methods: In the present study, 30 one-month old rabbits were included. The experimental group consists of 30 left knees of rabbits and were underwent patella lateral dislocation. And the control group consists of 30 right knees and no surgical procedure was performed. A CT scan was performed on each knee when the surgery was finished and at the time the rabbits were skeletal mature (5 months post-surgery). The angles of femoral version and tibial torsion were measured using a three-dimensional method and analyzed between the experimental group and control group. Results: The femoral version and tibia torsion in the experimental and control group immediately after surgery were not different significantly. However, 5 months after surgery, the femoral version angle of the experimental group (-5.50±6.13°) was significantly different with that of the experimental group (-10.90±4.74°)(P < 0.05). But the tibia torsion angle in the experimental group (7.17±7.25°) and control group (4.47±6.34°) were not significantly different (P = 0.144). Conclusion: From this study, patella dislocation can lead to alteration of femoral version in growing rabbits. This may indicate the early treatment for patella dislocation in children is particularly important to avoid torsional malalignment in the future. These findings may develop pathology and etiology of patella dislocation.

D Dimer

Objectives: Oral cancer is major health threat; with 90% mortality and ranks sixth among worldwide cancers. So to overcome this mortality; newer bio-markers are explored and one of such biomarker is D-dimer, which is end product of fibrinogen formed by plasmin. The raised levels of D-dimer play significant role in proliferation and progress of cancer cells. In cancers D-dimer is formed by dual action, where UPA (Urokinase type Plasminogen Activator) and Tissue factor play important role simultaneously. To understand correlation between D- dimer and oral cancers, by immunoturbidimetry; quantitative assay. Material and Methods: After obtaining consents of patients and Institutional ethical clearance, we randomly selected; age and sex matched; 216 samples. Further these samples were subdivides as oral cancer group and control group, consisting 108 samples in each group respectively. Results: Statistical analysis was done; using SPSS version 20, unpaired -T test, and one way ANOVA were applied. Plasma D-dimer levels were; 497.32±872.28μl/ml and 165.30±150.43 28μl/ml, among cancer and control groups respectively, (P≤ 0.0001), which was statistically highly significant. Conclusion: D-dimer is altered during carcinogenesis by activation of UPA and Tissue factors, and this distinguishes form routine levels of D-dimer. This suggests that, cancer cell biology is greatly affected by D-dimer levels during growth and spread of cancers. So raised levels of D-dimer can be considered during interventions of cancers, and incorporated as a biomarker. However for its scientific applications; there is need of further study, with collaborative approach and larger samples, to restrict cancer related mortalities.
