One important goal in cardiology is to prevent necrotic cell death in the heart. Necrotic cell death attracts neutrophils and monocytes into the injured myocardium. The consequences are fibrosis, remodelling and cardiac failure. The renin-angiotensin system promotes the development of cardiac failure. Recently, alternative renin transcripts have been identified lacking the signal sequence for a...

Evidence for recovery of surface membrane and its fusion with Golgi cisternae has been obtained previously in several glandular cells. This study was conducted to determine whether or not membrane is similarly retrieved from the surfaces of plasma cells from lymph nodes (of rats immunized with horseradish peroxidase [HRP]) and mouse myeloma cells (RPC 5.4 and X63 Ag 8 cell lines). Electron-dens...

The relation of the secretory immunoglobulin system in the colon to colorectal cancer and dysplasia has been examined by staining routine formalin-fixed, paraffin-embedded sections from cases of carcinoma, adenoma and ulcerative colitis for secretory component (SC), IgA and J chain. In carcinomas there was a close relation between SC synthesis and differentiation and a similar relation was appa...

Toxoplasma (toxoplasmosis) and Plasmodium (malaria) use unique secretory organelles for migration, cell invasion, manipulation of host cell functions, and cell egress. In particular, the apical secretory micronemes and rhoptries of apicomplexan parasites are essential for successful host infection. New findings reveal that the contents of these organelles, which are transported through the endo...

The patterns of pigment on the shells of mollusks provide one of the most beautiful and complex examples of animal decoration. Recent evidence suggests that these patterns may arise from the stimulation of secretory cells in the mantle by the activity of the animal's central nervous system. We present here a mathematical model based on this notion. A rather simple scheme of nervous activation a...

The study was conducted on ten healthy buffalo calves. The labial glands were distributed mainly at the commissure of lips and some isolated lobes in upper and lower lips. The gland was not encapsulated and parenchyma was comprised of secretory units and duct system. The adenomeres (secretory units) were mainly mucous with some serous and mixed type. Few serous demilunes capping the mucous alve...

BACKGROUND Diagnosis of premalignant endometrial lesions is a major challenge to pathologists. The D-score system is more reproducible than the WHO scheme, however it is not widely available, this study attest a simple custom-made workstation for estimation of the "D-score". MATERIAL AND METHODS Fifteen endometriam with low grade hyperplasia, fifteen proliferative and eight secretory phase en...
