Abstract:
The uptake of particles (colloidal gold, Thorotrast, ferritin) and hemoprotein tracers (catalase, horseradish peroxidase, microperoxidase) by pericardial glands and kidney was studied in Mytilus edulis L. Molecules smaller than 10 nm are taken up rapidly in large amounts by the pericardial cells from blood and pericardial fluid. These observations suggest that pericardial glands may be involved in ultrafiltration and reabsorption. Molecules of 6 nm are taken up only by the apex of the nephrocytes and their uptake is restricted.

Abstract:
ABSTRACT Dorsal vessel morphogenesis in Drosophila melanogaster serves as a superb system with which to study the cellular and genetic bases of heart tube formation. We used a cardioblast-expressed Toll-GFP transgene to screen for additional genes involved in heart development and identified tailup as a locus essential for normal dorsal vessel formation. tailup, related to vertebrate islet1, encodes a LIM homeodomain transcription factor expressed in all cardioblasts and pericardial cells of the heart tube as well as in associated lymph gland hematopoietic organs and alary muscles that attach the dorsal vessel to the epidermis. A transcriptional enhancer regulating expression in these four cell types was identified and used as a tailup-GFP transgene with additional markers to characterize dorsal vessel defects resulting from gene mutations. Two reproducible phenotypes were observed in mutant embryos: hypoplastic heart tubes with misaligned cardioblasts and the absence of most lymph gland and pericardial cells. Conversely, a significant expansion of the lymph glands and abnormal morphology of the heart were observed when tailup was overexpressed in the mesoderm. Tailup was shown to bind to two DNA recognition sequences in the dorsal vessel enhancer of the Hand basic helix-loop-helix transcription factor gene, with one site proven to be essential for the lymph gland, pericardial cell, and Svp/Doc cardioblast expression of Hand. Together, these results establish Tailup as being a critical new transcription factor in dorsal vessel morphogenesis and lymph gland formation and place this regulator directly upstream of Hand in these developmental processes.

Abstract:
The crustacean stomatogastric ganglion, which is situated in the ophthalmic artery, can be modulated by both intrinsically released molecules and hormones. In the crab Cancer borealis, over a dozen neuroactive compounds have been identified in the input axons that project into the stomatogastric neuropil. However, little is known about the modulator content of the two major neurohemal organs, the sinus glands and the pericardial organs, in this crab. We now report the results of a series of immunocytochemical experiments designed to identify putative neurohormones in these tissues. We find that the majority of modulators present in the input axons of the stomatogastric ganglion are also present in at least one of the neurohemal organs. Specifically, allatostatin-like, buccalin-like, cholecystokinin-like, FLRFamide-like, GABA-like, locustatachykinin-like, myomodulin-like, proctolin-like, red pigment concentrating hormone-like and serotonin-like immunoreactivities are all present in both the stomatogastric neuropil and at least one of the neurohemal organs. Thus, these substances are likely to serve a dual role as both local and hormonal modulators of the stomatogastric network. Two other substances, beta-pigment dispersing hormone and crustacean cardioactive peptide, are not present in the stomatogastric neuropil, but beta-pigment dispersing hormone immunoreactivity is present in the sinus glands and crustacean cardioactive peptide immunoreactivity is present in the pericardial organs. It is likely that crustacean cardioactive peptide exerts its influence on the stomatogastric neural circuit via hormonal pathways. Double-labeling experiments show that the patterns of modulator co-localization present in the stomatogastric neuropil are different from those in the neurosecretory organs, suggesting that few rules of colocalization hold across these tissues.

Abstract:
Disseminated lymphoma was diagnosed in an 8-year-old male bonobo ( Pan paniscus). The male bonobo presented with a 4–6 week history of dyspnea and facial swelling around the eyes; thoracic radiographs and computed tomography scan indicated a craniodorsal mediastinal soft tissue mass. Upon gross examination, there was a large, cream to white mass expanding the mediastinum and pericardial sac. The mass extended along the thoracic aorta and cranial vena cava, through the thoracic inlet, along and encircling the trachea, and bilaterally into the thyroid glands. Microscopically, neoplastic lymphocytes were present in the thymus, trachea, lungs, kidney, heart, and numerous other tissues. Immunohistochemical staining of neoplastic lymphocytes revealed diffuse immunoreactivity for cluster of differentiation (CD)3 indicating T-cell lymphoma. Routine viral screening was negative via polymerase chain reaction.

Abstract:
We have identified a novel alpha integrin subunit in Drosophila, that associates with betaPS integrin. We report the temporal expression of the gene encoding this integrin subunit, which we have called alphaPS3, throughout development and the localization of its expression during embryogenesis. AlphaPS3 RNA was localized to tissues undergoing invagination, tissue movement and morphogenesis such as salivary gland, trachea, midgut, dorsal vessel, midline of the ventral nerve cord, amnioserosa and the amnioproctodeal invagination. AlphaPS3 DNA localized to the chromosomal vicinity of scab (scb), previously identified by a failure of dorsal closure. Embryos homozygous for the 119 allele of scb had no detectable alphaPS3 RNA and the 1035 allele of scb contains a Pelement inserted just 5′ of the coding region for the shorter of the gene's two transcripts. Furthermore, mutations in the scb locus exhibit additional defects corresponding to sites of alphaPS3 transcription, including abnormal salivary glands, mislocalization of the pericardial cells and interrupted trachea. Removal of both maternal and zygotic betaPS produced similar defects, indicating that these two integrin subunits associate in vivo and function in the movement and morphogenesis of tissues during development in Drosophila. Phenotypic similarities suggest that laminin A is a potential ligand for this integrin, at least in some tissues.

Abstract:
Background: Dysfunction and anatomic abnormalities of the thyroid gland are among the most common diseases of the endocrine glands. The study has been undertaken with the aim to assess the different cardiovascular manifestations in patients of hypothyroidism and hyperthyroidism in Manipur and find out any correlation of it with age, sex, type of thyroid disorder and BMI. Materials and Method: The study was a cross sectional study of patients who were diagnosed as hypothyroid or hyperthyroid in the Department of Medicine, Regional Institute of Medical Sciences(RIMS), Imphal, Manipur. Clinical parameters including history and clinical examination were recorded including thyroid function testing, ECG, chest X-ray, trans-thoracic echocardiography. Results: Among 59 patients of thyroid disorder studied, 38 patients were found to be hypothyroid and 21 patients hyperthyroid. The average BMI in hypothyroid patient was 27.25. The average BMI in hyperthyroid patients was 25.41 which were lower than hypothyroid. Diastolic hypertension was found in 44.7% of hypothyroid patients. Sinus bradycardia and sinus tachycardia were the most common ECG findings in hypothyroid and hyperthyroid patients respectively. 15.8% had cardiomegaly on chest x-ray in hypothyroid patients while 9.5% had cardiomegaly in hyperthyroid patients. On echocardiographic evaluation, 13.1% and 9.5% had pericardial effusion in hypothyroid and hyperthyroid groups respectively.

Abstract:
<p>Data on fat tissue distribution by various fat deposits as well as internal organs of the bulls of Ukrainian beef breed at 22,5 months of age with different growth rates have been presented in the article. Growth rate was estimated by average daily gain from 8 to 12 months of age. Depending on the growth rates, the bulls were divided into fast growing group (with average daily gains exceeding 1090 g, averaged 1207 g) and slow growing group (below 1090 g/day, averaged 1015 g). It has been proved that the lowest percentage from the total amount of fat was attributed to pericardial fat tissue and intramuscular fat tissue, the highest - to intestines, omentum and skin. Cattle with relatively higher daily gains had higher ability to accumulate raw fat by 4,5%, including pericardial fat – in 2 times, perinephric fat – by 4,5%, intestinal fat – by 10,6% and intramuscular fat – by 24%. Weight of animal organs and body parts, such as head, internal organs etc. can be considered as a factor that determine slaughter percentage. Cattle with higher rates of gain have the tendency to have higher fat output from the carcass by 5.8% and lower weight of head (by 9,6 %), lungs (by 12,5 %), and internal secretion glands, including testicles (by 8,9 %). For the effective beef production, the bulls with lower rates of gain from 8 to 12 months of age are better suited, because they are relatively taller, which indicates higher rate of metabolism, and lower predispose to fat accumulation.</p>

Abstract:
The Wilms' Tumour gene WT1 has important functions during development. Knock-out mice were shown to have defects in the urogenital system and to die at embryonic day E13.5, probably due to heart failure. Using a lacZ reporter gene inserted into a YAC construct, we demonstrate that WT1 is expressed in the early proepicardium, the epicardium and the subepicardial mesenchymal cells (SEMC). Lack of WT1 leads to severe defects in the epicardial layer and a concomitant absence of SEMCs, which explains the pericardial bleeding and subsequent embryonic death observed in Wt1 null embryos. We further show that a human-derived WT1 YAC construct is able to completely rescue heart defects, but only partially rescues defects in the urogenital system. Analysis of the observed hypoplastic kidneys demonstrate a continuous requirement for WT1 during nephrogenesis, in particular, in the formation of mature glomeruli. Finally, we show that the development of adrenal glands is also severely affected in partially rescued embryos. These data demonstrate a variety of new functions for WT1 and suggest a general requirement for this protein in the formation of organs derived from the intermediate mesoderm.

Abstract:
Background. Castleman?s disease is an atypical lymphoproliferative disorder characterized by angiofollicular hyperplasia of lymph nodes. Histologically it can be classified into a hyaline-vascular type, plasma-cell type, and transitional (mixed-cell) type, while clinically localized type has been classified as unicentric, or generalized (multicentric) form of the disease. Case report. This paper presents a 21 years old male patient with multicentric Castleman?s disease, a transitional (mixed-cell) type. The disease was manifested by fever, generalized enlargement of peripherial lymph nodes, breast glands enlargement, hyperemia of the face, and weakness of the lower extremities. We found mediastinal lymphadenopathy, pleural and pericardial effusions, sensorimotor peripherial neuropathy and polyclonal hypergammaglobulinemia. The simultaneous presence of these manifestations of the disease (sensomotor peripheral neuropathy, lymphadenopathy, effusions endocrinopathy, polyclonal gammaglobulinemia and skin changes) is indentified as POEMS syndrome. The diagnosis of Castleman?s disease was based on the results of histopathologic analysis of mediastinal lymph node biopsies after thoracotomy. The patient was treated with corticosteroids (prednisone 80 mg daily for 2 weeks followed by 60 mg daily). A partial response was achieved after 4 months of treatment. Conclusion. A transitional type of multicentric Castleman?s disease may be present itself as POEMS syndrome. The effect of corticosteroid therapy in this form of the disease is unpredictable.

Abstract:
Echocardiography has become the most requested imaging modalities. It is the first line imaging in the diagnostic work-up and monitoring of most cardiac diseases. Echocardiography is harmless and combines low-cost high technology with easy accessibility. The advent of the new modalities such as harmonic imaging, tissue Doppler imaging, speckle tracking, real time 3-dimensional imaging, ad contrast cavity enhancement have also contributed to expand the role of echocardiography. It provides rapid quantitative information about cardiac structure and function, valvular motion, vascular system and haemodynamics at bedside. This imaging technique is considered an extension of the physical examination. Proper technical skills and knowledge are required for the optimal application of echocardiography. Disease-focused and succinct, the present handbook covers the information needed to perform and interpret echocardiogramsaccurately, including how to set up the echomachine to optimize an examination and how to perform echocardiographic disease assessment, and the clinical indicators, procedures, and contraindications. Sections include assessment of the left ventricular systolic dysfunction and diastolic function, discussion on ischaemic heart disease, heart valve disease, cardiomyopathies, pericardial disease, congenital heart disease, and many other aspects of echocardiology. Many talented people have contributed to the present handbook, which represents the pocket echocardiography book flagship of the European Association of Cardiovascular Imaging. This book is intended principally as a clinical guide to the broad field of echocardiography at a glance.

Abstract:
Introduction: Thymomas are rare malignant epithelial neoplasms arising in the thymus. These tumors are commonly located in the prevascular mediastinum but can also be found in other regions of the mediastinum, neck, pulmonary hilum, thyroid gland, lungs, pleura, or pericardium. This disease could be suspected as an incidental finding identified on imaging, local thoracic symptoms or due to a paraneoplastic syndrome. Pleural or pericardial effusions are the most common manifestations of more disseminated disease and may also cause thoracic symptoms. Extrathoracic metastases are seen in fewer than seven percent of patients at presentation, most commonly in the kidneys, extrathoracic lymph nodes, liver, brain, adrenals, thyroid, and bone. Case report: A 66-year-old, white female patient, with previous left mastectomy due to a phyllodes sarcoma in 1997. Diagnosed with malignant thymoma in 2013 and pleural involvement, undergoing systemic chemotherapy and surgery with complete remission of the disease at that time. Two years after, in 2015, presented with disease recurrence in the diaphragm, pleura and lymph nodes, undergoing new surgery, radiotherapy and a second line chemotherapy regimen. Over the years, the disease progressed despite the cancer treatment instituted. In December 2020, the patient presented nodulation in the right breast, with core biopsy suspicion of ductal carcinoma. Undergoing quadrantectomy with lymph node biopsy, with the surgical pathological report finding of thymoma metastasis, resected with free margins. The patient is currently at the 31st pembrolizumab cycle, in good clinical condition.
