Background. Equine herpesvirus type 1 (EHV-1) is responsible for respiratory disease in young animals, abortion in pregnant mares and neurological disease, whilst equine herpesvirus 4 (EHV-4) is mainly the causative agent of respiratory disorders and rarely causes abortion. These viruses are considered as one of the most clinically and economically important pathogens of horses and can be detected in a range of tissues. Scope and Approach. Serological methods are used to detect the presence and titre of specific antibodies to EHV-1 and EHV-4 in the sera of examined horses and are useful in epizootiological studies. Commercially available ELISA kits are able to differentiate specific EHV-1 and EHV-4 antibodies. EHV-1 and EHV-4 can both be isolated using susceptible cells such as primary horse cell cultures and other non-equine cells with visible cytopathic effect. Since standard diagnostic methods can be time consuming and arduous, the scope of many studies has been to develop and confirm the sensitivity and specificity of molecular diagnostic methods. Key Findings and Conclusions. Polymerase chain reaction (PCR) has proved to be a good screening method for the presence of latent infections of horses caused by these viruses, also making possible the rapid identification and differentiation of EHV-1 and- EHV-4 in the examined samples. Real-time PCR is a sensitive, specific and quantitative method that enables the determination of viral kinetics in infected horses. Genome sequencing can be used to discover mutations in the genomes of EHV-1 and EHV-4 as well as to track the spread of their different strains globally.

Research suggests that young sexual minority men (YSMM), particularly YSMM of color, are more likely to have dysregulated physiological stress responses as compared to their heterosexual counterparts. In addition, the quality of social relationships has been demonstrated to impact physiological stress patterns among young adults. One key indicator of social relationships is that of adult attachment, which refers to the types of socioemotional bonds that individuals form with peers, family, and romantic partners. However, the association between adult attachment and physiological stress functioning among diverse samples of YSMM has been underexplored. Thus, the current study sought to bridge this gap in the literature by exploring how race/ethnicity moderates the association between adult attachment and physiological stress patterns among Black versus White YSMM. N = 63 YSMM participated in a 5-day daily diary study in which they completed a baseline survey and provided saliva samples over the 5-day period in order to measure diurnal cortisol. Three-level hierarchical linear modeling was used in order to examine the association between race/ethnicity, adult attachment, and diurnal cortisol over the 5-day period. Results suggest that adult attachment avoidance was associated the cortisol awakening response (CAR) among YSMM. In addition, race/ethnicity moderated the association between adult attachment avoidance and the CAR such that YSMM who identified as Black had evidence of a more dysregulated physiological stress response as compared to YSMM who identified as White. Future research should focus on further unpacking the drivers of physiological stress patterns among White and Black YSMM.

Parents of children with special needs suffer from depression and anxiety disorder, as well as chronic insomnia and stress, this is confirmed by the presence of elevated cortisol levels and reduced immunity. In music therapy, rhythmic music and synchronization, especially music with drums, is used as a therapeutic activity capable of influencing mood improvement, stress reduction and relaxation in a therapeutic context, as it can fit into and adapt to many rhythmic complex and coherent ranges in the real world. This is unifying, creating a sense of security and belonging, allows music to be a facilitator of communicative and social interaction processes. The study uses Perceived Stress Scale (PSS), Cohen, et al., 1983), Improvisation Assessment Profile (IAP), Bruscia, 1987, Natural killer (NK) cell blood analysis, stress (cortisol) saliva analysis. The results of the study showed statistically a significant decrease in psychological and physiological stress patterns, improvements in immunity, interpersonal processes as well as intra-musical synchronization between the first and the tenth sessions.
