Two competing concepts, field cancerization and micrometastatic lesions, have been postulated to account for the high frequency of second primary tumors multicentric dysplasia in patients with head neck carcinoma.To provide insight into this process, authors examined histologically normal mucosa dysplastic tissue adjacent invasive tumor loss heterozygosity (LOH) at three commonly deleted loci. Tissues from 21 carcinoma oral cavity oropharynx were identified verified by a pathologist contain...

This paper presents the results of a study on impact new integrated medical educational design students' approaches to learning. Although program was based curriculum features identified in research literature as likely promote deeper learning, revealed more complex response from students. While proportion students reacted expected and changed approaches, significant subgroup moved opposite direction adopted surface approaches. Further analysis that specific – integration content,...

An important part of online courses is the delivery instruction via video lectures. Video lectures should use media effectively to reduce extraneous load and maximize cognitive processing, thereby helping students learn. Instructors may be able by varying number audio visual used. This study presents analysis from a survey (n = 1701) enrolled in cyber university South Korea investigate relationship between diversity load. Results showed negative Students who noted more types stated that they...

The purpose of this study was to compare shoulder range-of-motion (ROM) and strength values between bodybuilders nonbodybuilders. Fifty-four men (29 25 nonbodybuilders) the ages 21 34 years participated in study. Goniometric measurements were used assess flexion internal external rotation ROM. Isometric manual muscle tests performed using a handheld dynamometer. Shoulder flexion, rotation, abduction, prone retraction elevation tested. Independent t-tests determine levels statistical...

Purpose The paper aims to examine the effect of levels self-regulated effort (SRE) and cognitive load on watching completing video lectures used as main source instruction in online learning environments. Design/methodology/approach A survey provided data students’ engagement with lectures, their level SRE they perceived while lectures. relationships between these variables statistical significance were analyzed. Findings There three key findings: a positive relationship both lectures;...

Vascular targeted photodynamic therapy (VTP) is a nonsurgical tumor ablation approach used to treat early-stage prostate cancer and may also be effective for upper tract urothelial (UTUC) based on preclinical data. Toward increasing response rates VTP, we evaluated its efficacy in combination with concurrent PD-1 inhibitor/OX40 agonist immunotherapy tumor-bearing model.In mice allografted MB-49 UTUC cells, compared the effects of combined VTP those component treatments growth, survival, lung...

Context: There is a lack of research on the effects scapular tape shoulder joint repositioning. Objective: To quantify taping repositioning during flexion and abduction. Design: Repeated measures before after trial. Setting: Academic institution. Participants: 36 subjects without pathology. Intervention: Scapular with Main Outcome Measures: Lateral slide test, plumb-line assessment, depth measurement. Absolute error in abduction at 3 angles was measured. Results: No differences were found...
