Immunogenicity, pharmacokinetics, and therapeutic efficacy of three novel dimeric soluble tumor necrosis factor (TNF)-receptor I constructs [TNF-binding protein (bp)] were evaluated in 28 baboons, 12 of which were healthy and 16 were challenged with a lethal Escherichia coli bacteremia. The three constructs differed only in the number of extracellular domains of the TNF receptor I and were dime...
introduction: a keratocystic odontogenic tumor is a benign intra-bone mass originating from dental lamina or its residue. it represents 2–11% of jaw cysts, and has a slow but aggressive growth. the evaluation of molecular characteristics, immunohistochemistry, and genetic expression currently have no established classification regarding the evolution and pathophysiologic pattern of these lesion...
conclusions pnet/ews should be included in the differential diagnosis of renal tumors in symptomatic young adults. patients with localised pnet/ews treated with a combination of surgery and chemotherapy have an excellent chance of long-term survival, as in the case we have presented. introduction primitive neuroectodermal tumor (pnet)/ewing’s sarcoma (ews) belongs to a family of neoplasms that ...
introduction:neurogenic mediastinal tumors comprise a wide range of benign and malignant diseases. a group of these tumors, located at thoracic apex, sometimes spread to cervical spaces causing numerous surgical difficulties. in thoracotomy approaches, due to proximity of the tumors to major blood vessels, complete removal of these tumors from cervical spaces is impossible or may cause intraope...
introduction: different imaging modalities are used to evaluate salivary gland diseases, including tumors. ultrasonography (us) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. the aim of this study was to evaluate the role of us in differentiating malignant from benign parotid tumors, in the context of previous controversy...
introduction: notochord. although histologically benign, these tumors are locally aggressiveand present significant managment challenges . there arew some studies onevaluated the location, age and gender of the patients with chordoma in tworeferral centers in tehran.chordoma cases but there was no study about iranian cases. in this study weskull base chordomas are rare neoplasms arising from th...
Current methods to study angiogenesis in cancer growth and development can be difficult and costly, requiring extensive use of in vivo methodologies. Here, we utilized an in vitro adipocyte derived stem cell and endothelial colony forming cell (ADSC/ECFC) co-culture system to investigate the effect of lentiviral-driven shRNA knockdown of target genes compared to a non-targeting shRNA control on...
background: proliferation and expansion of cancer stem cells as spheroids were proved in previous studies. but, capability of primary tumor-derived stem cells to keep their unique properties in vitro is still disputed. so, the goal of this study was to isolate, expand and characterize of colon cancer-derived stem cells. material and methods: in the present work, colon cancer stem cells markers ...
The incidence of obesity, as a major health problem, has increased significantly over the past decades. This condition is associated with an increased risk of cancers, type 2 diabetes, and cardiovascular diseases. The current study aimed to investigate the effects of inflammation and changes of adipose tissue-resident immune cells on increasing the risk of cancer in obese individuals. In obesit...
