The aim of this study was to obtain reference values for diastolic cardiac function parameters in healthy dogs and to ascertain if significant differences exist between dogs of various age, weight and sex. The study was performed on 82 healthy dogs of different age and breed. Eleven param- eters were analyzed: peak velocity during early diastolic filling, acceleration time of early diastol- ic filling, deceleration time of early diastolic filling, total time of early diastolic filling, peak veloc- ity during late diastolic filling, acceleration time of late diastolic filling, deceleration time of late diastolic filling, total time of late diastolic filling, total time of early and late diastolic filling, ratio of peak velocities during early and late diastolic filling, isovolumetric relaxation time. The Dop- pler measurements used for general assessment of diastolic function in healthy dogs were signifi- cantly influenced by body weight, heart rate and age. No significant differences were found be- tween males and females. This study described the value of non-invasive echocardiographic assessment of diastolic function in healthy dogs.

In this study, we developed a SYBR Green I real-time PCR method for the rapid and sensitive detection of novel porcine parvovirus 7 (PPV7). Specific primers were designed based on the highly conserved region within the Capsid gene of PPV7. The established method was 1,000 times more sensitive than the conventional PCR method and had a detection limit of 35.6 copies. This method was specific and had no cross-reactions with PCV2, PCV3, PRV, PEDV, PPV1, and PPV6. Experiments testing the intra and interassay precision demonstrated a high reproducibility. Testing the newly established method with 200 clinical samples revealed a detection rate up to 17.5% higher than that of the conventional PCR assay. The established method could provide technical support for clinical diagnosis and epidemiological investigation of PPV7.

This article characterizes the etiology of temporomandibular disorder with particular emphasis on emotional factors that have a major impact on the development of these dysfunctions and the most common their symptoms. They mainly affect people in the third and fourth decade of life and women predominate among this group of patients.
The article analyzes the current literature (Pub Med Database, Scopus and EMBASE) in relation to the conditions in the work environment, which often constitute important causes of emotional tensions, constant state of mental tension and susceptibility to the effects of stressors, which have an impact on the state of functioning of the musculoskeletal system of the masticatory system.
Despite the high frequency of temporomandibular disorders, unfortunately only a few studies describe the influence of harmful factors related to the work environment, and own experience (information from the patient’s interview) and data from the literature indicate a significant share of these factors in the devel-opment of temporomandibular disorder. The relationships and anatomical connections affecting the influence of stressors on the functioning of masticatory muscles and temporomandibular joints are also discussed. In conclusion, it should be stated that the work environment and the emotional tensions generated in it constitute a serious sociological problem and increase the risk of developing and intensify the symptoms of TMD.
