Backgrounds and Study Aim: To determine whether the limb length-to-body ratio in young basketball players (15-18 years) is different in comparison to those who do not play basketball, and to contribute to the hypothesis that those with which body type can be more successful in basketball . Materials and Methods: The measurements were performed on 42 individuals (29 boys, 13 girls) who have played basketball for at least three years and 41 individuals (31 boys, 10 girls) who did not play basketball. A standard form was prepared for these measurements and the measurements were made according to this form. The data were summarized using mean and standard deviation values, and their accordance with normal distribution was evaluated with the Shapiro-Wilk test. The t-test was used for evaluating the independent samples. Values of p<0.05 were considered significant. The measurements were performed using a tape measure. Results: As a result of the measurements, the height/fa (forearm) ratio was 7.09 in non-basketball players and 6.71 in basketball players. The height/hl (hand length) ratio was 10.0 in non-basketball players and 9.06 in basketball players. The height /lll (lower limb length) ratio was 1.86 in non-basketball players and 1.73 in basketball players. The height /tl (thigh length) ratio was 3.28 in non-basketball players and 3.41 in basketball players. According to our findings, the ratio of forearm, hand, thigh and leg to body were increased in basketball players. There was no significant difference in terms of gender. Conclusion: Athletes possess anthropological and physiological characteristics specific to the sport in which they participate. In terms of limb length, there was an anthropometric difference between the young population who played basketball and the normal population.

Background: This study aims to investigate the muscarinic receptor-associated Z944 responses on hyperalgesia resulting from chronic constriction injury (CCI) of the rat sciatic nerve. Materials and Methods: A total of 72 male Wistar Albino rats (200-250 g) were randomly divided into eight groups. The right sciatic nerve CCI of Wistar Albino rats was performed except the Saline intraperitoneal (i.p.) group. Two weeks after the operations, pressure test of both paws and hot plate test were performed in the groups of Saline, CCI + Saline, CCI + DMSO (i.p.), CCI + 1 mg/kg Atropine (i.p), CCI + Z944 1, 3, 10 mg/kg (i.p) dose and CCI + 1 mg/kg Atropine + 10 mg/kg Z944. The locomotor activity test was performed before the tests. Results: The results of right paw pressure test ( p < 0.001) and hot plate test ( p = 0.032) of CCI + Saline group, compared to the Saline group test results, confirmed the development of mechanical hyperalgesia and thermal hyperalgesia of the CCI + Saline group. The locomotor activities of Saline and other CCI groups were higher than the activity of CCI + 1 mg/kg Atropine group ( p = 0.017). The dose-dependent increasing effect of Z944 in dose groups compared to the CCI + Saline group was determined, respectively, in the right paw pressure test ( p = 0.472, p = 0.006, p < 0.001) and the hot plate test ( p = 0.001, p < 0.001, p < 0.001). The left paw pressure test results of CCI + Saline group and Z944 dose groups were not statistically different ( p = 0.995, p = 0.159, p = 0.110, respectively). Also, there were no statistically differences between the CCI + Saline and the CCI + 1 mg/kg Atropine + 10 mg/kg Z944 groups according to right paw pressure ( p = 0.945), left paw pressure ( p = 0.763), and hot plate ( p = 0.817) tests results. Conclusion: The attenuation of the analgesic effect of Z944 by the non-selective muscarinic receptor antagonist atropine suggests that the analgesic activity of Z944 may be mediated, at least in part, through muscarinic receptor-dependent mechanisms.

Objective: This study aimed to evaluate how single-leg weight-bearing and double-leg weight-bearing radiographs affect knee osteoarthritis assessment and treatment planning. Methods: Fifty orthopedic physicians were asked to assess the knee radiographs of 10 female patients (mean age: 68 ± 6.6 years) presenting with knee pain. The radiographs were obtained in both double-leg and single-leg weight-bearing positions. Physicians were asked to determine the appropriate treatment plan (conservative management, unicondylar knee replacement, or total knee replacement). If they opted for surgical intervention, they were further asked to specify which prosthetic material they required to be available during surgery (a unicondylar knee prosthesis, both unicondylar and total knee prostheses, a total knee prosthesis, both total and revision knee prostheses). Treatment plans based on double-leg and single-leg weight-bearing radiographs were compared. Results: Conservative management was more frequently selected based on double-leg weight-bearing radiographs (P < .001). In contrast, the requirement for additional surgical materials was significantly higher for single-leg weight-bearing radiographs (P < .001). Specifically, 53.6% of physicians preferred having both total and revision knee prostheses available based on double-leg weight-bearing images, compared to 64.2% for single-leg images. Moreover, 31.2% of physicians upstaged their treatment plans after reviewing single-leg radiographs. Additionally, 13% of physicians opted for a total knee prosthesis based on double-leg weight-bearing images, whereas this proportion increased to 29% with single-leg weight-bearing images. Conclusion: Single-leg weight-bearing radiographs prompted more invasive treatment decisions, highlighting their clinical utility in detecting pathology that may influence surgical planning.
