Climate change erodes competitive hierarchies among native, alien and range-extending crabs.

Global warming and ocean acidification alter a wide range of animal behaviours, yet the effect on resource competition among species is poorly understood. We tested whether the combination of moderate levels of ocean acidification and warming altered the feeding success of co-occurring native, alien, and range-extending crab species, and how these changes affected their hierarchical dominance. Under contemporary conditions the range-extending species spent more time feeding, than the alien and the native species.

Quantitative analysis of follicle-stimulating hormone receptor in ovarian epithelial tumors: a novel approach to explain the field effect of ovarian cancer development in secondary mullerian systems.

The role of FSHR expression in ovarian cancer development is not clear. We examined quantitative expression of FSHR in different types of OET, presumed precursor lesions and peritoneal implants and further discussed FSH as a key growth-promotion factor for the process of ovarian epithelial tumorigenesis. Thirty-five primary OET specimens, including 5 serous cystadenomas, 4 papillary serous cystadenomas, 9 SBTs and 17 serous carcinomas, were examined for quantitative FSHR expression.

Atypical squamous metaplastic cells: reproducibility, outcome, and diagnostic features on ThinPrep Pap test.

Background: Atypical squamous metaplastic (ASM) cells are associated with high-grade squamous intraepithelial lesions (HGSIL) in many cases. The reproducibility of the diagnosis and biopsy follow-up results of cases designated as ASM were studied at Women and Infants' Hospital of Rhode Island.

Methods: Of 180 patients with ASM who the authors examined from January 1, 1998 to September 30, 1998, 147 (81.

p53 as a significant prognostic marker in endometrial carcinoma.

Although several studies have reported that p53 overexpression is associated with poor survival from endometrial cancer, this relationship might be confounded by a number of possible factors. The objective of this study was to examine the prognostic role of p53 overexpression in endometrial cancer when a panel of well-selected potential confounding factors were controlled. One hundred and twenty-five endometrial cancers were examined for p53 overexpression by immunohistochemistry (IHC).

Decreased luteinizing hormone receptor mRNA expression in human ovarian epithelial cancer.

Objectives: The objective of this study was to examine the distribution and cellular localization of luteinizing hormone receptor (LHR) in ovarian epithelial tumors (OETs) and their presumed precursor lesions-ovarian epithelial inclusions (OEIs). The clinicopathologic correlation of the receptor expression in OET was also examined.

Methods: Fifteen microdissected samples of ovarian surface epithelium (OSE), 20 OEIs from benign ovaries, and 141 OETs, including 48 cystadenomas, 33 borderline tumors, 60 carcinomas, and 5 metastatic cancers, were examined for LHR expression by using reverse transcription polymerase chain reaction and in situ hybridization.
