STUDY OBJECTIVES The role of radiofrequency ablation (RFA) for primary lung cancer remains poorly defined. The purpose of this "ablate and resect" pilot study was to evaluate the safety of performing RFA in patients with primary non-small cell lung cancer (NSCLC) and to characterize the histologic changes in tumor tissue following such ablation.

Saliva was collected from neonatal piglets in order to assess the secretory dynamics of cortisol in the newborn piglet. Saliva was collected from two litters of piglets (n = 16) from multiparous sows at 07.00, 11.00, 15.00 and 19.00 h on days 0, 1, 2, 4, 6, 10, 14, 18, 22, 26 and 30 post partum. Salivary cortisol concentration was determined by(More)
The optimum duration of test for the measurement of ADG, ADFI, feed:gain ratio [which is the reciprocal of the efficiency of gain (G:F) and therefore increases as the efficiency of gain decrease and vice versa], and residual feed intake was examined in growing pigs. Data from 144 hybrid (mainly Large White x Landrace) pigs involved in a longitudinal (n =(More)
Ninety hybrid (mainly Large White × Landrace) pigs from 2 experimental replicates were used to study the potential use of computed tomography (CT) as a nondestructive technology for estimating the chemical body composition of growing pigs. Body tissue components (lean, fat, and bone) of 6 live pigs from each sex (boars, gilts, and barrows) were assessed by(More)
BACKGROUND Vemurafenib, a novel selective small molecule inhibitor of BRAF, has recently been shown to be effective in the treatment of melanomas harboring the BRAF V600E mutation. Similar to the broad-spectrum RAF inhibitor sorafenib, vemurafenib induces development of squamous cell carcinomas and keratoacanthomas as a side effect of therapy. OBJECTIVE(More)
PURPOSE: The combination of the oral alkylating agent temozolomide and the oral multikinase inhibitor sorafenib was evaluated in advanced melanoma patients. EXPERIMENTAL DESIGN: Patients with metastatic melanoma (n = 167) were treated on four arms. All patients received sorafenib at 400 mg p.o. twice daily without interruption. Patients without brain(More)
INTRODUCTION The purpose of this study was to better characterize the clinical significance of cytokeratin immunohistochemistry (IHC)-only-positive lymph node metastases among patients with breast cancer. METHODS We performed a retrospective review of 334 patients who underwent sentinel lymph node (SLN) biopsy from 1 February 1997 through 31 July 2001.(More)
Adoptive immunotherapy of cancer patients with cytolytic T lymphocytes (CTL) has been hampered by the inability of the CTL to home into tumors in vivo. Chemokines can attract T lymphocytes to the tumor site, as demonstrated in animal models, but the role of chemokines in T-lymphocyte trafficking toward human tumor cells is relatively unexplored. In the(More)
Secretory characteristics of the ghrelin profile for the pig are still unknown. Our objective was to clarify the mechanisms that influence ghrelin secretion during differing feeding patterns. Pigs were initially fed a commercial pelleted diet offered ad libitum and blood samples collected for 24 h at intervals of 1 h. The pigs were then entrained for 17(More)
Ninety-six crossbred intact male pigs (34.5 +/- 3.5 kg BW) were allocated by weight and vocalization score to a 2 x 2 x 2 dynamic experimental design including two stocking densities (1 or 2 m(2)/pig), two temperatures (22 degrees C and 30 degrees C), and two short groupings of unfamiliar cohorts (six pigs as one pig per group, and six pigs per group).
