fasciolosis diagnosis, due to low sensitivity of coprological diagnostic method has been challenging for a long period. in this study, dot-elisa, one of the simplest and the most sensitive tests in this regard, was evaluated using excretory-secretory antigens of fasciola hepatica to diagnose human fasciolosis three groups consisting of patients infected with fasciolosis (n= 95), patients with o...

Morphological, structural and developmental features of fruits and seeds of Vismia guianensis (Aubl.) Choisy. are here presented, with the purpose to elucidate their structure and to contribute to taxonomical and ecological studies of the family. The fruit is a berry and the "rind" is constituted by the exocarp and by the subepidermal layers which constitute the mesocarp. The reddish pulp, rich...

INTRODUCTION Cystic fibrosis or mucoviscidosis is a genetically caused disease. The intensity of disease and histopathological changes grow throughout the life. According to the literature, pathological changes characteristic of cystic fibrosis become noticeable around the sixth month of life. CASE REPORT After amniocentesis of a 5-lunar month-old fetus had been done, which confirmed cystic f...

Polycystic kidney disease (PKD) is a genetic disorder characterized by growth of fluid-filled cysts predominately in kidney tubules and liver bile ducts. Currently, the clinical management of PKD is limited to cyst aspiration, surgical resection or organ transplantation. Based on an observation that PPARγ agonists such as pioglitazone and rosiglitazone decrease mRNA levels of a Cl(-) transport ...

Branching morphogenesis (BrM) is a basic developmental process for the formation of the lung, kidney, and all exocrine glands, including the salivary glands. This process proceeds as follows. An epithelial downgrowth invaginates into underlying mesenchyme, and forms a cleft at its distal end, which is the site of dichotomous branching and elongation; this process of clefting and elongation is r...

The use of natural gums, taken from the exudates and extracts of plants, has been given a strong impulse due to both the many and lucrative possibilities for industrialization and to the excellent international market. A gum or resin of a yellowish color, soluble in water, and which presents a great potential for industrialization, appears on the trunk and branches of the cashew tree; that is k...

The evolution of the kidney has had a major role in the emigration of vertebrates from the sea onto dry land. The mammalian kidney has conserved to a remarkable extent many of the molecular and functional elements of primordial apocrine kidneys that regulate fluid balance and eliminate potentially toxic endogenous and xenobiotic molecules in the urine entirely by transepithelial secretion. Howe...

By the immunoperoxidase technique, immunoglobulin A(IgA) was demonstrated in 50% of human hepatocytes. The positively stained cells showed a tendency towards periportal clustering. Very few plasma cells were identified in the liver. The intrahepatocyte IgA is most probably derived from serum and on its way to the bile ducts. Secretory component (SC) had the same distribution as that of IgA. The...

An amino acid-defined, folate-deficient diet was used to investigate the regulation of pancreatic glycine N-methyltransferase in vivo. This enzyme modulates the ratio of S-adenosylmethionine to S-adenosylhomocysteine and is inhibited by bound folate in vitro. Rats were fed either a folate-deficient diet, a folate-supplemented diet (pair-fed to the deficient group), or a folate supplemented diet...
