“…The potential positive impact of chamomile on egg quality indicators may be attributed to several factors, including heightened feed consumption, enhanced diet digestibility, and greater absorption of nutrients in avian species ( Ezeldien et al, 2023 ). According to a study by Shirley and Tohala (1983) , laying hens fed diets containing OTA exhibited substandard eggshell quality with blood spots in their eggs. Observations were made regarding thin rubbery shells that exhibit increased susceptibility to breakage during instances of ochratoxicosis epidemics in the field ( Jewers, 1990 ).…”

Background: Precise sex assessment relies over dimorphic dimensions measuring among unknown human remains is a necessary prerequisite for individuals' identification. Clavicle is a flat short bone appears to be better maintained than long bones. Anthropometric analyses of clavicles to determine the sex are evaluated in different populations with high accuracy. Three-dimensional computed tomography (3D-CT) pictures are an effective technique for this. Objective:The aim of the current study was to study sexual dimorphism of the clavicle, as well as establishment of sex prediction equation among Libyan people by utilizing measurements of the clavicle which obtained from 3D-CT images. Subjects and methods: A total of 50 males and 50 females sexes dimensions were measured from 3D CT scans of the left clavicle: C1, C2 and C3 maximum clavicular length, midshaft circumference, and maximum diameter of the midshaft. C4, C5 and C6 indicated minimum midshaft diameter, maximum sternal end, and acromial end widths, respectively. Results: All the studied measurements in the left clavicle showed a statistical significant increase in males compared to females. C4 was the most single sexually dimorphic dimension of the left clavicle with 90% accuracy. Stepwise discriminant analyses of clavicular variables (C2, C4, and C6) yielded high accuracy at the rate of 99 % (99 % crossvalidated). Conclusion: 3D-CT morphomertric analyses of clavicle provide valuable data for identification of sex in modern Libyan population and can be used in forensic investigations.

“…Gender variation in the lateral and medial ends of the clavicle shows that the lateral end in females is slightly below the medial end, while in males, it is at the same level or higher than the medial end. 2 The clavicle, except at its medial end, is the first bone to ossify; it has two primary and one secondary ossification center. The weakest point of the clavicle is the junction between its curvatures, and fractures commonly occur by falling on the outstretched hand.…”

“…This epiphysis is the last to ossify and fuse at the ages of 18 and 20 years and at the end of 25 to 26 years, respectively. 1,2 There are certain types of clavicular fractures reported in recent studies, which indicates that surgical treatments are the best. This has led to renewed interest in the clavicular anatomy.…”

Background The S-shaped collar bone lies horizontally at the root of the neck and is one of the most common bones to fracture. The symmetry of the clavicle bone differs between males and females, so the present study was conducted to assess the symmetry of the clavicle in healthy adults of the Indian population in the Dakshina Karnataka region. Methods The data for this cross-sectional study were retrospectively collected from 138 adult patients who all underwent chest computed tomography (CT) for clinical reasons. Patients younger than 18 years and those with bony fractures, trauma, or other deformities were excluded. Axial chest CT images were used to trace the anatomy of the clavicle. The curved planar reconstruction technique was used to trace the maximum length of the bilateral clavicle. Results There were 138 patients of both sexes. Patients ranged in age from 20 to 80 years. The chi-square test was used to investigate whether sex and clavicle symmetry were related. In women, bilateral symmetry and asymmetry were 42.5 and 41.2%, respectively, while in men, they were 57.5 and 58.8%, respectively; hence, there was no significant correlation (p-value = 0.877) between clavicle symmetry and sex. A linear-by-linear association test was performed to ascertain the relationship between the variance in clavicle symmetry and age. It was noted that 51 individuals had asymmetry and 87 had symmetry. The patients were further divided into three age groups. There were 34, 67, and 37 individuals in the 20 to 40, 41 to 60, and 61 to 80 years age groups, respectively. Clavicle symmetry was 27.6% in the 20 to 40 and 61 to 80 age groups and 44.8% in the 41 to 60 age group. The percentages of asymmetry were 19.6, 54.9, and 25.5% in the 20 to 40, 41 to 60, and 61 to 80 years age groups, respectively, with no correlation between age and clavicle length symmetry (p-value = 0.643). Conclusion Regardless of age or sex, the population under study had symmetric clavicles. As a result, the assumption of symmetry may be accepted in some clinical scenarios, such as simple fractures, but caution should be exercised when designing fixatives and surgical cases.
