Toxoplasma gondii is a zoonotic protozoan pathogen that infects many endothermic vertebrates, including humans; the domestic cat and other felids serve as the definitive host. Macropodids are considered highly susceptible to toxoplasmosis. Here, we describe the clinical, pathologic, and immunohistochemical findings of an outbreak of systemic toxoplasmosis in a mob of 11 red kangaroos (Macropus rufus), with high morbidity (73%) and mortality (100%) rates. Affected animals had either severe and rapidly deteriorating clinical conditions or sudden death, which was correlated with widespread necrotizing lesions in multiple organs and intralesional T. gondii organisms identified via MIC3-specific immunohistochemistry and confirmed by REP529-specific rtPCR. Quantification of parasites demonstrated the highest parasite density in pulmonary parenchyma compared with other tissues. Our study highlights the continued importance of this severe condition in Australian marsupials.Exosomes are small, cell-derived vesicles of 30-100 nm that participate in cell-to-cell communication. They are released by many cells, such as dendritic cells (DC), lymphocytes, platelets, epithelial cells, endothelial cells (EC), and are found in most body fluids, including blood, saliva, urine, and breast milk. The exosomes released from cells within the cardiovascular system may contain either inhibitors of calcification in normal physiological conditions or promoters in the pathological environment [atherosclerosis (AS), and Chronic Kidney Disease (CKD)]. The exosomes of the vascular smooth muscle cells (VSMCs) are novel players in vascular repair processes and calcification. Several studies have shown that the cytoplasmic contents of exosomes are rich in a variety of proteins, nucleic acids, and lipids. ALK targets Currently, exosomal micro RNAs and proteins are increasingly being recognized as biomarkers for the diagnosis of several diseases, including those of kidney and liver, as well as different types of cancer. In this review, we summarize recent advances in the role of exosomes in vascular calcification and their potential applications as diagnostic markers as well as a brief overview of the role of stem cell-derived exosomes in cardiovascular diseases.Lawsonia intracellularis is an obligate intracellular bacterium associated with enteric disease in pigs. Clinical signs include weight loss, diarrhea, and, in some cases, sudden death. The hallmark lesion is the thickening of the intestinal mucosa caused by increased epithelial cell replication, known as proliferative enteropathy. The immune response to L. intracellularis is not well defined, and detection of the infection, especially in the early stages, is still a significant challenge. We review here the main approaches used to identify this important but poorly understood pathogen. Detection of L. intracellularis infection as the cause of clinical disease is confounded by the high prevalence of the pathogen in many countries and that several other pathogens can produce similar clinical signs. A single L. intracellularis-specific ELISA and several amplification assays are available commercially to aid detection and surveillance, although histopathology remains the primary way to reach a conclusive diagnosis. There are major gaps in our understanding of L. intracellularis pathogenesis, especially how the host responds to infection and the factors that drive infection toward different clinical outcomes. Knowledge of pathogenesis will increase the predictive value of antemortem tests to guide appropriate interventions, including identification and treatment of subclinically affected pigs in the early stages of disease, given that this important manifestation reduces pig productivity and contributes to the economic burden of L. intracellularis worldwide.While a considerable research base demonstrates the positive effects of 8-week secular mindfulness courses, it remains unclear to what degree their participants continue to engage with mindfulness practices; and there is a dearth of published reports on longer-term mindfulness interventions. Studies have also tended to focus on clinical "effectiveness," with less attention given to participants' own construal and expectations of mindfulness. To address these gaps, the study reported here implemented a year-long mindfulness program for a group of 20 individuals with long-standing health conditions who gradually transitioned to self-guiding. Their experiences, expectations, and understanding of mindfulness were investigated through the lens of descriptive phenomenology. The findings revealed that mindfulness practice did bring therapeutic improvement but that it was a multi-faceted process where an individual's intentionality toward practice was key, with a clear division between those pursuing an "embodied integrated" mindfulness and those viewing it as a stress management tool.Diabetes mellitus is a serious chronic disease in which the oxidant-antioxidant balance is impaired, causing many complications, including hepatopathy. In this study, the effects of short-term and low-dose N-acetylcysteine (NAC) administration on the biochemical, proinflammatory, and oxidative stress parameters in the liver tissue of diabetic rats were investigated. Twenty-four adult male Wistar albino rats weighing approximately 250-300 g were divided into 4 groups (n = 6) Control, Streptozotosin (STZ)-induced diabetes (DM), NAC treatment (60 mg/kg), and STZ-induced diabetes treated with NAC (DM+NAC; 60 mg/kg). NAC treatment was administered intraperitoneally as a single daily dose for 7 days. At the end of the experiment (3 weeks), blood and liver samples were collected for biochemical parameter analysis. Lipid peroxidation, antioxidant parameters, and nitric oxide (NOx) levels were determined by spectrophotometric method. Tissue inflammation parameters were evaluated by ELISA. Lipid peroxidation, proinflammatory cytokines, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values increased significantly with diabetes. NAC treatment significantly decreased serum ALT and AST levels and proinflammatory cytokines in the diabetic group. Liver glutathione (GSH) and NOx levels increased significantly in the DM+NAC group (p less then 0.05). While NAC treatment reduced lipid peroxidation in the liver, it improved the inflammatory response and antioxidant status. The beneficial effect of NAC treatment may be due to its antioxidant activity and the resulting increased level of GSH. The results show that low-dose and short-term NAC treatment had a positive effect on oxidative damage and inflammation in liver tissue. NAC can be used as a potential antioxidant in diabetes to prevent hepatopathy.
