Angiogenesis has been shown to be related to tumour behaviour, prognosis and response to treatment in many different tumour types. The aim of this study was to examine the relationship between angiogenesis and tumour behaviour and response to treatment in pituitary adenomas. The microvessel density (MVD) of pituitary tumours was assessed by counting blood vessels labelled with 3 different endot...

Pituitary tumours express both somatostatin and dopamine receptors. Medical treatment with somatostatin analogues is a cornerstone of GH- and TSH-secreting tumours, while treatment with dopamine agonists is a cornerstone of prolactin-secreting tumours. Dopamine agonists have also demonstrated some efficacy in patients with GH- and TSH-secreting adenomas. Neither ACTH-secreting nor clinically no...

Most functional phaeochromocytomas/paragangliomas produce noradrenaline and/or adrenaline. Those that produce dopamine are rare. We describe the distinguishing clinical features of dopamine-secreting phaeochromocytomas and paragangliomas from those that secrete noradrenaline/adrenaline and the impact on their management. We present a case of a dopamine-secreting paraganglioma from our instituti...

background: application of adjuvants with microbial origins is a recently highlighted approach in the vaccinology trials. archaeosomes are among these microbial compounds with both adjuvant and liposomal activities and features. methods: in the present study, recombinant hbsag encapsulated into methanobrevibacter smithii (m. smithii) archaeosomes. balb/c mice immunized with this compound and hu...

CONTEXT The development of neoplasia is an important concern associated with inflammatory bowel disease (IBD), especially colorectal cancer (CRC). OBJECTIVES Our aim was to determine the incidence of intestinal and extraintestinal neoplasias among patients with inflammatory bowel disease. METHODS There were retrieved information from 1607 patients regarding demographics, disease duration an...

BACKGROUND The cancer risk associated with gastric non-invasive neoplasia (formerly dysplasia) is debated. This prospective long term follow up study investigates the clinicopathological behaviour of non-invasive gastric neoplasia (and related lesions), focusing on the cancer risk associated with each different histological phenotype. PATIENTS AND METHODS A total of 118 consecutive cases (nin...

The objective of this study was to determine the effect of neurotrophin-secreting Schwann cell implants on the urinary bladder after spinal cord contusion. One hour after severe spinal cord contusion at the T8 to T11 level, carbon filaments containing nonsecreting Schwann cells, brain-derived neurotrophic factor (BDNF)-secreting Schwann cells, neurotrophin-3 (NT-3)-secreting Schwann cells, or S...

PURPOSE The incidence of colorectal neoplasia has increased among patients with longstanding and extensive ulcerative colitis (UC). Therefore, surveillance colonoscopy has been widely recommended. However, there is controversy about the impact of cancer surveillance, and ways to improve its effectiveness are being sought. The estrogen receptor (ER) gene shows age-related methylation in the colo...
