AbstractCallitrichidae are small, arboreal New World primates that utilize a variety of locomotor behaviors including trunk-to-trunk leaping (TTL) and horizontal locomotion which involve differential functional demands. Little is known about the relationship between the preferred locomotor behavior and musculoskeletal architecture of these primates. In this study, we compared the musculoskeletal architecture of selected shoulder muscles in two cadavers each of the trunk-to-trunk leaper Cebuella pygmaea and the mainly pronograde quadrupedally moving Saguinus imperator subgrisescens. Contrast-enhanced microfocus computed tomography (µCT) was used to virtually dissect the cadavers, produce muscle maps, and create 3D reconstructions for an image-based analysis of the muscles. Muscle lengths, muscle volumes, and osteological muscle moment arms were measured, and the anatomical cross-sectional areas (ACSA) were calculated. We expected the muscles of the forelimb of S. imperator to be larger in volume and to be relatively shorter with a larger ACSA due to a higher demand for powerful extension in the forelimbs of this horizontally locomoting species. For C. pygmaea, we expected relatively larger moment arms for the triceps brachii, supraspinatus, infraspinatus and subscapularis, as larger moment arms present an advantage for extensive vertical clinging on the trunk. The muscles of S. imperator were relatively larger in volume than in C. pygmaea and had a relatively larger ACSA. Thus, the shoulder muscles of S. imperator were suited to generate relatively larger forces than those of C. pygmaea. Contrary to our expectations, there were only slight differences between species in regard to muscle lengths and moment arms, which suggests that these properties are not dependent on the preferred locomotor mode. The study of this limited dataset demonstrates that some but not all properties of the musculoskeletal architecture reflect the preferred locomotor behavior in the two species of Callitrichidae examined.

Abstract. Ultrasound has been established as an important diagnostic tool in assessing vascular abnormalities. Standard B-mode and Doppler techniques have inherent limitations with regards to detection of slow flow and small vasculature. Contrast-enhanced ultrasound (CEUS) is a complementary tool and is useful in assessing both the macro- and microvascular anatomy of the aorta. CEUS can also provide valuable physiological information in real-time scanning sessions due to the physical and safety profiles of the administered microbubbles. From a macrovascular perspective, CEUS has been used to characterize aortic aneurysm rupture, dissection and endoleaks post-EVAR repair. With regard to microvasculature CEUS enables imaging of adventitial vasa vasorum thereby assessing aortic inflammation processes, such as monitoring treatment response in chronic periaortitis. CEUS may have additional clinical utility since adventitial vasa vasorum has important implications in the pathogenesis of aortic diseases. In recent years, there have been an increasing number of studies comparing CEUS to cross-sectional imaging for aortic applications. For endoleak surveillance CEUS has been shown to be equal or in certain cases superior in comparison to CT angiography. The recent advancement of CEUS software along with the ongoing development of drug-eluting contrast microbubbles has allowed improved targeted detection and real-time ultrasound guided therapy for aortic vasa vasorum inflammation and neovascularization in animal models. Therefore, CEUS is uniquely suited to comprehensively assess and potentially treat aortic vascular diseases in the future.

Background: Deliberate self-harm (DSH) occurs with high frequency among clinical and nonclinical youth populations. Although depression has been consistently linked with the behavior, not all depressed individuals engage in DSH. Aims: The current study examined maladaptive coping strategies (i.e., self-blame, distancing, and self-isolation) as mediators between depression and DSH among undergraduate students. Methods: 202 students from undergraduate psychology courses at a private university in Southern California (77.7% women) completed anonymous self-report measures. Results: A hierarchical regression model found no differences in DSH history across demographic variables. Among coping variables, self-isolation alone was significantly related to DSH. A full meditational model was supported: Depressive symptoms were significantly related to DSH, but adding self-isolation to the model rendered the relationship nonsignificant. Limitations: The cross-sectional study design prevents determination of whether a casual relation exists between self-isolation and DSH, and obscures the direction of that relationship. Conclusions: Results suggest targeting self-isolation as a means of DSH prevention and intervention among nonclinical, youth populations.

Abstract. Previous research suggests that parenting style influences the development of the needs for achievement, power, and affiliation. The present study investigated the relationship between parenting style and another important motive disposition – the need for autonomy – in a sample of Singapore university students ( N = 97, 69% female), using a cross-sectional and retrospective design. It was predicted that an authoritative perceived parenting style would relate positively to the implicit need for autonomy ( nAut), the explicit need for autonomy ( sanAut), and the congruence between these two motive dispositions. Authoritative maternal parenting was found to positively associate with sanAut, while maternal parenting was not found to associate with nAut, or with nAut/ sanAut congruence. Paternal parenting was not associated with any of the dependent variables.

Autism is still a nightmare for most parents. Parents with autism can be very stressful when dealing with a hyperactive child's behavior, aggressive and passive. Stress experienced by parents of children with autism will affect the ability of parents in the parenting role, especially in relation to coping strategies have in dealing with problems of children. The participation of parents is crucial the success of socializing with children with autism in the general population. This study aims to determine the relationship of coping strategies parents of autistic children and parenting parents. This type of research is an analytic correlation with cross sectional approach. The population in this study were all parents of autistic children in SLB Muhammadiyah Mojokerto numbering 15 people. Samples in this study were all parents of autistic children in SLB Muhammadiyah Mojokerto which totaled 15 people by using total sampling technique. Collecting data using questionnaires. Data analized use cross tabulation, presented in a frequency distribution. On cross-tabulation obtained results tend to use maladaptive coping strategies permissive parenting that is 8 (53.3%), there are also respondents who use adaptive coping strategies using authoritarian parenting as much as one person (16.7%), and adaptive coping strategies tend using democratic parenting style as much as 5 people (33.3%). Expected parents still seeking information to broaden their parents on coping strategies of parents of autistic children and parenting parents as well as parents to give special attention for children with autism to the development and advancement of their lives because they have the same rights as any other normal child.

Objective: Rabies, one of the oldest and fatal infectious diseases known to human race, is transmitted by infected dogs. The global target of zero dog-mediated rabies human deaths has been set for 2030; however, the realization of this goal poses challenges in most low-income countries where rabies is endemic due to weak surveillance. Dogs have been increasingly deployed for domestic uses over the years, especially for security purposes. This study assessed the assessment of knowledge and practice of vaccination of dogs against rabies by dog owners. Materials and Methods: A cross-sectional community-based study was employed to study 400 dog owners in Makurdi metropolis through multistage sampling techniques. Sighting of valid dog vaccination card was used as criteria for current vaccination. Bivariate analysis was carried out to establish the relationship between the respondent knowledge of rabies and dog vaccination with significant value set at P < 0.05. Results: The mean age of the respondents was 31 (Â ± 0.8) years, majority of them had tertiary and secondary education (40.0% and 39.0%, respectively), 26.0% were traders, and 50.0% were married. Overall, 73.0% of the respondents had good knowledge score, 61.0% had seen at least a rabid dog in their life time, and 74.0% have a history of dog vaccination, but evidence of up to date vaccination of dogs by owners was seen in only 18.0% of all the vaccination cards sighted. The relationship between the educational status of the respondents, their knowledge score, and their dog vaccination was statistically significant (P < 0.05). Conclusion: Knowledge of rabies among dog owners in Makurdi was good, but the practice of dog vaccination was poor. Educational status was a good predictor of practice. Awareness campaign on dog vaccination should be strengthened and adequate measures should be put in place at the veterinary hospitals in Makurdi for vaccination of dogs.
