Secretory carcinoma (SC) is a rare recently described entity that has characteristics similar to those of secretory breast carcinoma. We report case 23 years old male with swelling on the parotid gland. The ultrasonography guided fine needle aspiration cytology was performed mass. Cytologically, background aspirate composed inflammatory cells admixed mucinous material. There were isolated as mu...

The stem cells of the small intestine are multipotent: they give rise, via transit-amplifying cell divisions, to large numbers of columnar absorptive cells mixed with much smaller numbers of three different classes of secretory cells--mucus-secreting goblet cells, hormone-secreting enteroendocrine cells, and bactericide-secreting Paneth cells. Notch signaling is known to control commitment to a...

The aim of this study was investigating chronic diarrhea, its etiologies, clinical features and outcomes in infancy.Materials and Methods Retrospective study investigating infants hospitalized in the gastroenterology department of Tehran tertiary care center.The main de...

Membrane and secretory trafficking are essential for proper neuronal development. However, the molecular mechanisms that organize secretory trafficking are poorly understood. Here, we identify Bicaudal-D-related protein 1 (BICDR-1) as an effector of the small GTPase Rab6 and key component of the molecular machinery that controls secretory vesicle transport in developing neurons. BICDR-1 interac...

In exocrine glands, secretory proteins synthesized in the rough endoplasmic reticulum (RER) exhibit vectorial transport from ER through a succession of membrane-bounded components such as Golgi complex, condensing vacuoles and secretory granules. The secretory granules migrate to particular locations within the cell close to the apical membrane prior to the release of their contents into the ac...

background: candida albicans is one of the most important opportunistic pathogens that suppress immunologic mechanisms of the host. it is speculated that structural and secretory proteins of c. albicans have immunomodulatory effects in cancer. objective: to evaluate the effects of c. albicans structural and secreted proteins on intratumoral cd4/cd8 ratio as well as the survival rate in balb/c t...
