1. Tumor carcinoide na vesícula biliar em cão
ABSTRACT Carcinoid is a neoplasia that arises from dispersed cells of the neuroendocrine system. This tumor is uncommon in animals, and its occurrence in the gallbladder is rare. A male Basset Hound dog’s corpse was taken to the Univerdade Federal de Minas Gerais to be analyzed by the Veterinary Pathology sector, without a description of its previous histo

2. Effect of lncRNA HULC knockdown on rat secreting pituitary adenoma GH3 cells
Pituitary adenoma is one of the most common tumors in the neuroendocrine system. This study investigated the effects of long non-coding RNAs (lncRNAs) highly up-regulated in liver cancer (HULC) on rat secreting pituitary adenoma GH3 cell viability, migration, invasion, apoptosis, and hormone secretion, as well as the underlying potential mechanisms. Cell tra

3. Medullary thyroid carcinoma – Adverse events during systemic treatment: risk-benefit ratio
ABSTRACT Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor originating from parafollicular C cells of the thyroid and associated with mutations in the proto-oncogene REarranged during Transfection (RET). The prognosis of MTC depends on clinical stage, with a 95.6% 10-year survival rate among patients with localized disease and 40% among patien

4. Effects of nitric oxide on magnocellular neurons of the supraoptic nucleus involve multiple mechanisms
Physiological evidence indicates that the supraoptic nucleus (SON) is an important region for integrating information related to homeostasis of body fluids. Located bilaterally to the optic chiasm, this nucleus is composed of magnocellular neurosecretory cells (MNCs) responsible for the synthesis and release of vasopressin and oxytocin to the neurohypophysis

5. Leptina: um modulador central das respostas imunes. / Leptin: a central modulator of imune responses.
Leptin is a mediator of both neuroendocrine and immune responses, and has been associated with several autoimmune diseases. Our objective was to study the importance of leptin in modulating the immune response in experimental transplantation, with emphasis on its role in the plasticity of T lymphocytes and dendritic cells (DC). We observed that animals lepti

6. Imuno-histoquímica das células neuroendócrinas do tubo gastrintestinal de Pimelodus maculatus (Siluriformes, Pimelodidae) dos reservatórios de Funil e Santa Branca. / Immunohistochemistry of neuroendocrine cells of the gastrointestinal tube of Pimelodus maculatus (Siluriformes, Pimelodidae) from Funil and Santa Branca reservoirs.
The objective of this work is to analyze the influence of habitat on the regional distribution and relative frequency of gastrointestinal neuroendocrine cells that secrete cholecystokinin octapeptide (CCK-8), gastrin and serotonin (5-HT) in Pimelodus maculatus. All told, 18 fish were utilized, 12 of them taken from Funil Reservoir in the state of Rio de Jane

7. Análise histológica e morfométrica de componentes neuroendócrinos do intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) / Hystological analysis and morphometry of the neuroendocrine componentes of the small intestine of the opossum Didelphis aurita (Wied-Neuwied, 1826)
The objectives of this work were to aspects of the histology and morphometry of the small intestine of adult and post- puberty big-eared opossum Didelphis aurita. The morphometric description of the speciess small intestine focused on the mucous, sub-mucous and muscular layers. The entero- endocrinal-cells and the cells of the myoenteric nervous and sub-muco

8. PREPARATION OF LYOPHILIZED KIT OF HYNIC-[Tyr3]-OCTREOTATE AND LABELING STUDIES WITH 99m-TECHNETIUM / Preparo do reagente liofilizado HYNIC-[Tyr3]-Octreotato e estudo de marcação com Tecnécio-99m
The development of radiolabeled molecules with high specificity for an organ or tumor has been contributed to the precise diagnostic in nuclear medicine. Somatostatin labeled derivatives constitutes a particular example of labeled peptide applied in the localization of neuroendocrine tumors. Nowadays, the 111In-DTPA-octreotideo is the radiopharmaceutical app

9. Individual risk prediction of node and distant metastasis based on lymphangiogenic intensity in typical pulmonary carcinoid tumor / Predição do risco individual de metástase linfática e hematogênica em função da intensidade da linfangiogênese no tumor carcinóide típico broncopulmonar
Typical pulmonary carcinoids are neuroendocrine cells proliferations and they were former considered lung adenomas with no hematogenic or lymphatic metastatic potential. However, it is known that up to 20% of patients develop metastatic disease. It is mandatory that new studies be developed due to the variation in clinical presentation of these patients. It

10. Mutation screening in the VHL, SDHB and SDHD genes in patients with sporadic pheochromocytoma and/or paraganglioma / Rastreamento de mutações nos genes VHL, SDHB e SDHD em pacientes portadores de feocromocitoma ou também, paraganglioma esporádico
Pheochromocytomas are neuroendocrine tumors composed of chromaffin cells that produce and secrete catecholamines as well as a variety of neuropeptides, whose most common clinical manifestation is arterial hypertension. Twelve to 24% of the apparently sporadic pheochromocytomas, present germline mutations in genes previously associated to inherited familiar s

11. Efeitos da alga Chlorella vulgaris sobre a resposta hematopoética e capacidade funcional de neutrófilos em ratos submetidos ao estresse agudo físico e psicogênico e infectados com Listeria monocytogenes / Effects of the algae Chlorella vulgaris on hematopoietic response and functional activity of neutrophils in rats submitted to physical and psychogenic acute stress and infected with Listeria monocytogenes
Evidence suggests that a variety of stressors can activate the hypothalamic control of the neuroendocrine and autonomic responses involved in the production´s control of blood cells and their release from bone marrow to circulation. The algae Chlorella vulgaris (CV) has several imunomodulatory activities, as the stimulation of hematopoietic cells and the ac

12. Use of neuron-specific enolase for assessing the severity and outcome of neurological disorders in patients
Neuron-specific enolase (NSE) is a glycolytic enzyme present almost exclusively in neurons and neuroendocrine cells. NSE levels in cerebrospinal fluid (CSF) are assumed to be useful to estimate neuronal injury and clinical outcome of patients with serious clinical manifestations such as those observed in stroke, head injury, anoxic encephalopathy, encephalit
