OBJECTIVES The present study was designed to compare the secretion patterns of two cardiac hormones--A-type (atrial) and B-type (brain) natriuretic peptides--from the ventricles in patients with old myocardial infarction. BACKGROUND Plasma levels of these two natriuretic peptides are increased, and their secretion from the ventricles is augmented, in patients with congestive heart failure. ...

Leaf venation is diverse across plant species and has practical applications from paleobotany to modern agriculture. However, the impact of vein traits on plant performance has not yet been tested in a model system such as Arabidopsis thaliana. Previous studies analysed cotyledons of A. thaliana vein mutants and identified visible differences in their vein systems from the wild type (WT). We me...

australian grapevine viroid (agvd), an apscaviroid of the family pospiviroidae, was recently identified in vineyards of southern iran. it had a relatively wide host range and caused stunting, leaf deformation, mottling and vein clearing in experimental hosts upon mechanical inoculation of nucleic acid extracts or agroinfiltration of the viroid infectious cloned dna. predicted secondary structur...

Eight dogs underwent combined hepatic/portal vein catheterization and infusion of D4-cortisol in order to determine the relative contributions of the viscera and liver to splanchnic cortisol production. D4-cortisol concentrations progressively decreased from 2.6 +/- 0.1 to 2.4 +/- 0.1 to 1.7 +/- 0.1 microg/dl (P < 0.001 by ANOVA) from hepatic artery to portal vein to hepatic vein, respectively,...

Letter to the Editor Comments on ‘Hemispheric Retinal Branch Vein Occlusions’ by F. J. Gómez-Ulla de Irazazabal et al., published in Ophthalmologica, Basel 198:14–22 (1986) I was interested to read the paper by F.J. Gomez-Ulla de Irazazabal et al. The authors made some erroneous and misleading statements on the subject which require to be rectified. The two retinal venous trunks, draining the u...

Replantation is an ideal technique for reconstruction following fingertip amputation as it provides ‘like for like’ total reconstruction of the nail complex, bone pulp tissue and skin with no donor-site morbidity. This study is a clinical research on distal finger replantation and its classification, the purpose is to get better understanding of the neurovascular anatomy of distal finger, guide...

A 67 year old lady with hypertension, type two diabetes mellitus, hypothyroidism, depression and deep vein thrombosis, independent in activities of daily living who was admitted one month history lethargy. She noted to have deterioration the living, complaining shortness breath.

kalchouyeh area in southwest of naein is located in the urumieh-dokhtar volcano-plutonic belt. mineralization occurred mainly as disseminations and veinlets hosted by trachy-andesite and pyroxene andesites. for mineralogy, alteration, fluid inclusion and geochemical studies, the two major mineralized zones: a (larger vein) from the north-northwest and b (smaller vein) from the east-southeast of...

Inducible NO synthase (iNOS) is expressed by macrophages and smooth muscle cells in atherosclerotic lesions. Previously, we have established a mouse model for vein graft arteriosclerosis by grafting autologous jugular veins or vena cava to carotid arteries. Using this model, we studied the role of iNOS in the development of vein graft arteriosclerosis in iNOS / mice. Four weeks after grafting, ...
