paragangliomas are extra-adrenal counterparts of pheochromocytomas and are found at various anatomical sites such as the retroperitoneum, mediastinum, jugular foramen and carotid bifurcation, the latter two fonns being coined as chemodectomas. the vertebral column, especially the llullbar zone, is one of the rarest sites to be involved by paragangliomas. these lesions may have secretory functio...

the distinction between malignant and benign pheochromocytoma has always been a diagnostic challenge over the last decades. to date, the only reliable criterion is metastasis. the aim of the present study was to investigate the possible expression of pituitary-tumor transforming gene (pttg1) and retinoblastoma (rb) in benign and malignant pheochromocytoma. paraffin blocks of 44 and 11 patients ...

background hepatocellular carcinoma (hcc) is the fifth most common fatal cancer and an important healthcare problem worldwide. there are many studies describing the prognostic and predictive effects of epidermal growth factor receptor 2 (c-erb-b2) and epidermal growth factor receptor 1 (egfr), transmembrane tyrosine kinases that influence cell growth and proliferation in many tumors. objectives...

background: colorectal adenocarcinoma is one of the most prevalent and treatable malignancies of the gastrointestinal tract. recent in vitro studies have demonstrated the anticancer effect of calendula officinalis extract on a tumor cell line derived from colorectal cancers. the inhibitory effect of this extract ranges from 70- 100% and an in vitro study has demonstrated that calendula officina...

We classify the paracontact Riemannian manifolds that their Riemannian curvature satisfies in the certain condition and we show that this classification is hold for the special cases semi-symmetric and locally symmetric spaces. Finally we study paracontact Riemannian manifolds satisfying R(X, ξ).S = 0, where S is the Ricci tensor.
