Therefore, it is essential to create population-specific values to maximize the accuracy rate of sex estimation. The objective of this study was to evaluate the orbital region morphometrically for sex determination in a Saudi Arabian population using CT scan images. This study included 456 CT images (228 males and 228 females; age range, 18–58 years). Six orbital measurements and the orbital index of both sides were evaluated to determine sexual dimorphism and laterality using an independent <i>t</i>-test. Sex was estimated using discriminant function analysis. Based on the orbital index, the orbit was classified into megasemes, mesosemes, and microsemes. All the measurements were significantly greater in males than females, but the orbital index showed no significant sexual dimorphism. No significant asymmetry was found in all orbital dimensions. The univariate discriminant function of the orbital measurements showed an accuracy rate between 83.8 and 70%. The multivariate analysis classified the orbital dimensions into male (93%) and female (92.1%) to the highest level of accuracy. In Saudis, the megaseme category was the most prevalent form of orbit. The right orbit height (83.8%), left orbit height (80.7%), right orbit width (79.4%), and left orbit height (79.4%) were the most reliable variables that could be used in sex determination. According to multivariate analysis, the overall accuracy rate for determining sex was 92.1%. While the present study data may not be used alone for sexing a complete skull, there must be various occasions in which this new standard will contribute to determining sex in forensic contexts.</p></div>","PeriodicalId":7816,"journal":{"name":"Anatomical Science International","volume":"99 1","pages":"118 - 126"},"PeriodicalIF":1.2,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10340609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parotid gland tissues were obtained from dissection of donated cadavers. The gland was cut perpendicular to the facial nerve plane at 5 mm intervals, and the pieces were embedded in paraffin, thinly sliced, and stained.

Previous research found a link between the tarsometatarsal joint obliquity and the hallux valgus angle. Nevertheless, most studies relied on radiographs that lack 3D evidence. This study used 3D analysis to investigate the morphological differences in the medial cuneiform between hallux valgus and normal feet. In this study, twenty-three hallux valgus feet and twenty-three normal feet were scanned with computed tomography and 3D models of medial cuneiforms were reconstructed. Medial cuneonavicular and the first tarsometatarsal joint surfaces of the medial cuneiform were manually extracted. To obtain the obliquity angle of the medial cuneiform and curvature of the medial cuneonavicular joint, the joint surfaces were approximated to planes and spheres. Furthermore, the orientations of two joint surfaces were accessed through a novel positioning method. No significant difference was found in the cuneiform obliquity between hallux valgus and normal feet. Hallux valgus and normal groups did not differ significantly in any of the medial cuneiform joint orientations. The medial cuneiform in hallux valgus had a larger curvature diameter of the medial cuneonavicular joint (<i>P</i> = 0.029), indicating a flatter surface. The results demonstrated that the generally supported atavism (i.e., tarsometatarsal joint obliquity) does not exist in the hallux valgus feet.

Pregnant rats were divided into five groups: control and four experimental groups (25 mg/kg, 50 mg/kg, 100 mg/kg, 200 mg/kg PSE). Between 1 and 20 days of pregnancy, PSE was given to them by gavage. Weights and heights of fetuses isolated by cesarean on the 21st day were measured. Ossification of femur and humerus was examined by three different methods mentioned earlier. Depending on the dose increase, all morphometric data, ossification rate and bone length of the fetuses were decreased. Besides, it was determined that the amount of Calcium in the bone tissue decreased in the analyzes made with SEM–EDX Analysis. The data obtained from this study reveal that the use of PSE during pregnancy disrupts the existing balance in the bone and negatively affects ossification due to the dose increase.
