Theileriosis is an important tick-borne protozoosis that causes high morbidity and mortality in cattle. In this study, the pathological and clinical characteristics of cattle experimentally infected with Theileria annulata were investigated. The clinical findings revealed typical signs of bovine theileriosis, including fever, enlargement of superficial lymph nodes, anemia, and respiratory distress. The most common pathological features were petechial and ecchymotic hemorrhages on the mucosa and serosal surface, severe jaundice, pulmonary edema and emphysema, multifocal necrosis and numerous ulcerations in the abomasum, congestion and marble-like discoloration of the spleen, and severe intestinal ecchymotic hemorrhages. The main histological characteristics were proliferation and infiltration of lymphocytes, plasma cells, and macrophages in the lymph nodes, spleen, and lymph node mass. Macroschizonts were observed in the cytoplasm of lymphocytes and macrophages of the lymph nodes and spleen. This study has significance for basic research and the clinical detection and diagnosis of Theileria annulata infection and can aid the prevention and control of theileriosis and future studies of the pathogenic mechanisms.

Exercise has long been recognized as a beneficial living style for cardiovascular health. It has been applied to be a central component of cardiac rehabilitation for patients with chronic heart failure (CHF), coronary heart disease (CHD), post-acute coronary syndrome (ACS) or primary percutaneous coronary intervention (PCI), post cardiac surgery or transplantation. Although the effect of exercise is multifactorial, in this review, we focus on the specific contribution of regular exercise on the heart and vascular system. We will summarize the known result of clinical findings and possible mechanisms of chronic exercise on the cardiovascular system.

Cell suspensions from draining lymph nodes of immune and nonimmune rats were reacted in vitro with 125I-labeled antigens. In light microscopic radioautographs of smears, 17% of the immunized cells were tagged by specific antigen; 2.0% of control cells were positive. In electron microscopic radioautographs, 90% of the labeled elements from immune donors were lymphocytes, blast and plasma cells; 10% were monocytes-macrophages or other elements, including naked nuclei. 15% of the labeled cells from control materials were lymphocytes and plasma cells, while 85% were monocytes-macrophages and naked nuclei. Within cell suspensions derived from immunized animals there were almost twice as many lymphocytes marked by isotope as plasma cells, and the lymphocytes ranged in morphology from mature monoribosomal elements to immature polyribosomal cells. Antibody-forming cells fixed labeled antigen at their surfaces. The monocyte-macrophage class was distinguished by a high mean grain count and by distribution of grains within cytoplasmic vacuoles and lysosomes.

Response Dynamics

To mount an immune response, lymphocytes must recirculate between the blood and lymph nodes, recognize antigens upon contact with specialized presenting cells, proliferate to expand a small number of clonally relevant lymphocytes, differentiate to antibody-producing plasma cells or effector T cells, exit from lymph nodes, migrate to tissues, and engage in host-protective activities. All of these processes involve motility and cellular interactions—events that were hidden from view until recently. Introduced to immunology by three papers in this journal in 2002, in vivo live-cell imaging studies are revealing the behavior of cells mediating adaptive and innate immunity in diverse tissue environments, providing quantitative measurement of cellular motility, interactions, and response dynamics. Here, we review themes emerging from such studies and speculate on the future of immunoimaging.

Introduction: Non-communicable Diseases (NCDs) are the major public health problem that leads to high morbidity and mortality in the world including Nepal. Government of Nepal has launched the Multi-sectoral NCD Action Plan in 2014 and established NCD and Injuries Poverty Commission in 2016 for the management and control of NCDs nevertheless the implementation status and its outcomes are not identified till date at the local level. Objectives: To explore the preparedness of the local government for the prevention and control of NCDs at Gaindakot, Nawalpur, Nepal. Methodology: A qualitative study was conducted in the Gaindakot municipality; Nawalpur to document the key informant's perspectives on health system's preparedness to prevent the potential impacts of NCDs. Face to face Indepth interview was performed using open-ended questions. Interview guidelines were prepared on the basis of building blocks of health system. Information was processed basis on thematic analysis. Result: The study revealed that health section has NCD preparedness structure but need to strengthening for the better delivery of health services. The study highlights that screening services and the medicine for major NCDs like hypertension and diabetes were available at local level. Limited budget was allocated and health workforce was not trained for NCDs prevention and control. There was no reporting mechanism for NCD related data from local level. Conclusion: Basic medicine and screening services were provided from the local level to the selected NCDs such as hypertension and diabetes. There was no provision of reporting NCD related information and health workforce were not trained to respond NCDs. Local level health system strengthening is an urgent need to address the increasing burden of NCDs.

SUMMARYTh2-biased inflammation with eosinophilia and IgE production is a hallmark of helminth infections. It is pronounced in hyperreactive onchocerciasis patients (‘sowda’ or ‘local form’), who efficiently kill microfilariae resulting in severe dermatitis and lymphadenitis. In contrast, hyporeactive patients (‘generalised form’) tolerate high microfilarial loads. This is thought to be mediated by regulatory CD4+ T cells and macrophages producing suppressive cytokines such as IL-10 and transforming growth factor-beta (TGF-β). We investigated whether hyperreactivity was reflected by lower local TGF-β production, analysing stable latent TGF-β1 expression in onchocercomas, lymph nodes and skin from hyperreactive and hyporeactive patients by immunohistochemistry. TGF-β expression was compared with that of IgE, IgG1, IgG4, and the antigen-presenting, CD4+ T cell-inducing MHC class II molecule HLA-DR. TGF-β was weakly and less frequently expressed by various cell types in onchocercomas, skin and lymph nodes from hyperreactive compared to hyporeactive patients. This applied to reactions around living and dead adult worms as well as dead microfilariae. Antigen-presenting cells strongly expressed HLA-DR in both forms, but their numbers were reduced in hyperreactive nodules. Plasma cells produced more IgE and IgG1, but less of the anti-inflammatory antibody IgG4 in hyperreactive onchocercomas. In conclusion, hyperreactivity is linked with reduced local expression of TGF-β, HLA-DR and IgG4, which might contribute to the insufficient down-regulation of inflammation via TGF-β- and HLA-DR-induced regulatory lymphocytes.

SARS-CoV-2 is a new entity in the globe studied vigorously in the present world. The estimated populations are around 47 million people who are affected by the virus and around 300,000 (16th May 2020) deaths resulted from the outbreak. The rate might keep on increasing due to the non-availability of a proper vaccine, following proper management with epidemiological studies, and displacement of contact individuals as a source of transmission in particular viral-prone regions. CoVID 19 is on its vigorous spread leading to a global impact on lots of sectors. The outreaching impacts play a role in international politics, scientific developments, and economic crises over the world, and global relations among the countries. This model attempts to determine the possible impacts and outcomes of the Pandemic over the international level and some possible ways to handle it effectively. An unpredictable catastrophe in the present scenario of the world is following a high range of public health hazards. Analytical plotted data assembles for imposing in multidisciplinary segments to cure and control morbidity, a mortality rate of disease clusters, and hotspots zone. The contagious outbreak was reprogrammed as a pandemic from Wuhan in China through the transmissible chain of human contacts. Currently, the infective chain is spreading day by day with high morbidity in the United States, Europe, Scandinavian countries, and India. The transmissible chain of the virus needs to break until any effective medicine or vaccine is launched.

The growing prevalence of progressive myopia and its disabling consequences explains the elaboration of reliable diagnostic markers and new treatment strategies based on the research results of molecular mechanisms underlying the development of the condition. The paper reviews recent basic pathogenetic research studies which have greatly broadened the awareness of the deep causes of progressive myopia associated with the activity of certain growth factors, local and systemic protein metabolism, and regulation of hormonal and neural processes. Practical clinical guidelines for new criteria of diagnosis and control of myopia are published as they could be useful while selecting individual treatment plans including indications to sclera-strengthening therapy and its evaluation. The results may be promising in the elaboration of systemic and local medications for the prevention of myopia progression, which should address the regulation of connective tissue disorders, hormonal shifts, and imbalanced autonomic nervous system.

Abstract Background Fibrous sclerosing tumours and hypertrophic lesions in IgG4-related disease (IgG4-RD) are formed in various organs throughout the body, but disease in the oral region is not included among individual organ manifestations. We report a case of ossifying fibrous epulis that developed from the gingiva, as an instance of IgG4-RD. Case presentation A 60-year-old Japanese man visited the Department of Oral and Maxillofacial Surgery, Gunma University Hospital, with a chief complaint of swelling of the left mandibular gingiva. A 65 mm × 45 mm pedunculated tumour was observed. The bilateral submandibular lymph nodes were enlarged. The intraoperative pathological diagnosis of the enlarged cervical lymph nodes was inflammation. Based on this diagnosis, surgical excision was limited to the intraoral tumour, which was subsequently pathologically diagnosed as ossifying fibrous epulis. Histopathologically, the ossifying fibrous epulis exhibited increased levels of fibroblasts and collagen fibres, as well as infiltration by numerous plasma cells. The IgG4/IgG cell ratio was > 40%. Serologic analysis revealed hyper-IgG4-emia (> 135 mg/dL). The patient met the comprehensive clinical diagnosis criteria and the American College of Rheumatology and European League Against Rheumatism classification criteria for IgG4-RD. Based on these criteria, we diagnosed the ossifying fibrous epulis in our patient as an IgG4-related disease. A pathological diagnosis of IgG4-related lymphadenopathy was established for the cervical lymph nodes. Concomitant clinical findings were consistent with type II IgG4-related lymphadenopathy. Conclusions A routine serological test may be needed in cases with marked fibrous changes (such as epulis) in the oral cavity and plasma cells, accompanied by tumour formation, to determine the possibility of individual-organ manifestations of IgG4-related disease.
