context the current literature suggests that minimally invasive surgery is associated with faster recovery and less morbidity than open surgery. parenchyma-sparing pancreatectomy is minimally invasive surgery, including enucleation, inferior head pancreatectomy, spleen-preserving distal pancreatectomy, and central pancreatectomy, combined pancreatectomy such as inferior head pancreatectomy plus...

conclusions we can conclude that treatment of af using a right-sided minithoracotomy approach and rf energy in patients undergoing cardiac surgery for various valve diseases is feasible, safe, and reproducible. objectives our aim is to evaluate the feasibility, safety, and immediate plus medium-term results of concomitant af ablation therapy in patients undergoing minimally invasive valve surge...

BACKGROUND Liver fibrosis remains one of the most important predictors of sustained virological response (SVR) in this era of direct-acting antiviral treatment of chronic hepatitis C. We compare non-invasive fibrosis assessment with liver biopsy (METAVIR) in terms of their ability to predict SVR by telaprevir (TVR)-based triple therapy. METHODS This prospective study consisted of 108 patients...

Metastasis is the reason for most cancer death, and a crucial primary step for cancer metastasis is invasion of the surrounding tissue, which may be initiated by some rare tumor cells that escape the heterogeneous primary tumor. In this study, we isolated invasive subpopulations of cancer cells from human non-small cell lung cancer (NSCLC) H460 and H1299 cell lines, and determined the gene expr...

Follicular patterned lesions of the thyroid are problematic and interpretation is often subjective. While thyroid experts are comfortable with their own criteria and thresholds, those encountering these lesions sporadically have a degree of uncertainty with a proportion of cases. The purpose of this review is to highlight the importance of proper diligent sampling of an encapsulated thyroid les...

PURPOSE CTLs are a prominent immune component infiltrating many solid tumors. These cells are considered to be a manifestation of host-immune response to the tumor; however, their prognostic significance remains a subject of considerable debate. The objective of this study was to evaluate the distribution pattern and prognostic value of CD8(+) T cells in endometrial carcinoma. EXPERIMENTAL DE...

BACKGROUND Accurate information is currently lacking regarding the values of positive margins (M(+)) and lymph node (LN) metastases as independent predictors of postoperative recurrence in invasive and noninvasive intraductal papillary mucinous neoplasms (IPMNs) of the pancreas. METHODS A comprehensive online literature search identified all types of primary studies that included M(+) and LN ...

BACKGROUND Concern that the use of exogenous testosterone may increase breast cancer risk coexists with rising use of this medication in the United States. We sought to examine the relationship between the use of estrogen plus testosterone (E + T) therapy (esterified estradiol plus methyltestosterone) and the occurrence of breast cancer. METHODS A total of 31,842 postmenopausal participants i...

The growing international trade in live wildlife has the potential to result in continuing establishment of nonnative animal populations in the United States. Snakes may pose particularly high risks as potentially invasive species, as exemplified by the decimation of Guam's vertebrate fauna by the accidentally introduced brown tree snake. Herein, ecological and commercial predictors of the like...

Invasive Alien Plants occur in numbers differing by orders of magnitude at subsequent invasion stages. Effective sampling and quantifying niches of rare invasive plants are quite problematic. The aim of this paper is an estimation of the influence of invasive plants frequency on the explanation of their local abundance. We attempted to achieve it through: (1) assessment of occurrence of self-re...
