1. SARS-CoV-2 leading to acute pancreatitis: an unusual presentation
ABSTRACT During SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) pandemic, the etiologic agent of COVID-19, several studies described the involvement of other tissues besides the respiratory tract, such as the gastrointestinal tract. Angiotensin-converting enzyme-2, the functional virus host cell receptor expressed by organs and tissues, seems to

3. Anatomical and histological study of the liver and pancreas of two closely related mountain newts Neurergus microspilotus and N. kaiseri (Amphibia: Caudata: Salamandridae)
ABSTRACT Anatomical and histological examinations were conducted on the digestive glands of two closely related mountain newts, Neurergus microspilotus (Nesterov, 1916) and Neurergus kaiseri Schmidt, 1952. In N. microspilotus and N. kaiseri the major digestive glands comprise a very large liver and a small pancreas. In both species the liver has two distinct

4. Comparative efficacy of Belzer or Euro-Collins solutions for pancreatic preservation during cold ischemic storage in rats
PURPOSE: To compare the efficacy of different types of solutions (Belzer or Euro-Collins) for the preservation of rat pancreas during cold ischemia.METHODS: Thirty Wistar rats were divided into three groups according to the perfusion or storage solution: Group E (perfusion and storage in Euro-Collins solution); Group B (perfusion and storage in Belzer soluti

5. Doença do armazenamento lisossomal causada pela ingestão espontânea de Sida carpinifolia em cervos Sambar (Cervus unicolor) cativos no Rio de Janeiro. / Lysosomal storage disease caused by spontaneous ingestion of Sida carpinifolia in captive-Sambar deer (Cervus unicolor) in Rio de Janeiro State, Brazil.
Cases of diseases induced by toxic plants in domestic herbivores are well reported throughout the world and have been studied also in Brazil. However, not much is known about the epidemiological and pathological aspectos of these conditions in free-living wildlife or bred in captivity. The risk for developing the toxicoses in captivity has been increasing, s

6. Histology of the liver of Oligosarcus jenynsii (Ostariophysi, Characidae) from Los Padres Lake, Argentina
The liver is an organ notable for its sensitivity to a great variety of environmental factors. It is composed of a parenchyma divided into irregular lobules by the exocrine pancreas or hepatopancreas; the pancreatic cells are arranged around a branch of the portal vein. The hepatocytes are radially arranged in cords around a central sinusoid. The liver histo

7. Efeito do ciclamato de sódio sobre o pâncreas exócrino fetal de ratos: estudo cariométrico e esterelógico.
Cyclamate, a sweetening substance derived from N-cyclo-hexyl-sulfamic acid, is largely used as a non-caloric artificial edulcorant in foods and beverages as well as in the pharmaceutical industry. This study aims at evaluating different karyometric and stereological quantitative parameters in the exocrine pancreas of rat fetuses . In five pregnant rats, a do

8. Prevalencia de seis mutações no gene CFTR em portadores de fibrose cistica da região de Campinas
Cystic Fibrosis (FC) is a genetic autossomic recessive disease with an incidence of 1/2.500 life births and a carrier frequency of 1/25 in the caucasian population. The disease is progressive and present as a clinical manifestation the respiratory chronic blockage, male infertility and deficiency to gain weight caused for the damage to the exocrine pancreas.

9. Significance of the site of origin of pancreatic exocrine adenocarcinoma.
The pancreatic head and neck constitute less than half (mean 46 +/- 5%) of the whole pancreas. There is no difference in the concentration of ductal epithelium between the head and the body of the pancreas. The preponderance of pancreatic exocrine tumours which arise in the head of the pancreas compared to the body is not, therefore, due to a larger number o

10. Cell-specific enhancers in the rat exocrine pancreas.
Pancreatic amylase, chymotrypsin B, and trypsin I genes are specifically expressed in the exocrine pancreas. The 5'-flanking regions of these genes direct preferential expression of a linked reporter function (chloramphenicol acetyltransferase) in the pancreatic exocrine cell line AR4-2J. The sequences upstream of the amylase and chymotrypsin genes that are

11. Peripheral tolerance to allogeneic class II histocompatibility antigens expressed in transgenic mice: evidence against a clonal-deletion mechanism.
To examine the effects of aberrant expression of class II major histocompatibility complex (MHC) proteins on tolerance development, transgenic mice expressing the I-Ad genes under control of the pancreatic elastase promoter were produced. Such transgenic mice express I-Ad exclusively on exocrine pancreas, without expression in thymus or by lymphocytes. No sp

12. The bHLH protein PTF1-p48 is essential for the formation of the exocrine and the correct spatial organization of the endocrine pancreas
We have generated a mouse bearing a null allele of the gene encoding basic helix–loop–helix (bHLH) protein p48, the cell-specific DNA-binding subunit of hetero-oligomeric transcription factor PTF1 that directs the expression of genes in the exocrine pancreas. The null mutation, which establishes a lethal condition shortly after birth, leads to a complete
