Abstract Pituitary adenylate cyclase activating polypeptide (PACAP) is a neuropeptide with widespread occurrence and diverse functions. PACAP binds to specific PAC1 non-specific VPAC1/2 receptors. considered as growth factor, it plays important roles during development participates in reparative processes. Highest concentrations are found the nervous system endocrine glands, where several funct...

What are they? Ediacarans are a highly distinctive assemblage of fossil organisms, apparently all marine. Most typical are frondose, discoidal and segmented forms. Their overall taxonomic diversity is modest, but there is considerable disparity and they include one rather bizarre group with prominent three-fold body symmetry. A striking feature of many forms is their modular construction and th...

A total of 1921 children were chosen by simple cluster method and general demographic and anthropometric information regarding the subjects was extracted f...

BACKGROUND: The scope of this consensus was to review the biological processes of soft tissue wound healing in the oral cavity and to histologically evaluate soft tissue healing in clinical and pre-clinical models. AIMS: To review the current knowledge regarding the biological processes of soft tissue wound healing at teeth, implants and on the edentulous ridge. Furthermore, to review soft tiss...

A 66-year-old man was diagnosed with a gastric submucosal tumor. Endoscopic ultrasound (EUS) revealed an iso/hypoechoic mass in the third layer. No malignant cells were detected in a histological examination. Yearly follow-up endoscopy and EUS showed the slow growth of the tumor. Endoscopic submucosal dissection (ESD) was performed and a glistening tumor was resected. The lesion showed a multin...

In the present study, we have examined the origin and growth pattern of the beta cells in pancreatic islets, to determine whether a single progenitor cell gave rise to all the precursors of the islets, or if each of a few progenitor cells is the founder of a different islet, or if each islet is a mixture of cells originating from a pool of progenitor cells. Aggregation mouse chimaeras where the...

different opinions exit in histological typing of bone cysts. epidermoid cysts are very rare as the small numbers of published cases indicate. they arises following preceding trauma exclusively in distal phalanges and skull. the roentgenogram shows a round osteolytic resion with no trabecular pattern. we observed 2 cases of epidermoid cyst of finger in imam khomeini hospital central path depart...

Recently multiple cutaneous leiomyomas, uterine leiomyoimatosis and renal cancer have been described as a cancer syndrome with autosomal dominant pattern of inheritance.We report a 79-year-old man who presented with multiple hyperkertotic erythematous nodules on his right leg with histological diagnosis of pilar leiomyoma. In his past medical history several systemic co...

breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...
