Physiological correlates with perceived exertion during deep water running.

The purpose of this study was to investigate the relationship between perceived exertion and physiological variables during deep water running. Deep water running to VO2 peak was performed in 3-min. stages at leg speeds controlled by a metronome.

Perceptual responses to deep water running and treadmill exercise.

Perceived exertion during deep water running and treadmill exercise was measured to examine gender and mode specific responses. Deep water running to VO2 peak was performed in 3-min. stages at leg speeds controlled by a metronome.

Renal oncocytoma and granular renal cell carcinoma. A comparative clinicopathologic and DNA flow cytometric study.

Twenty-three renal oncocytomas and 18 granular renal cell carcinomas (GRCC) were comparatively studied clinicopathologically and by DNA flow cytometry to delineate their differences. Of the patients with renal oncocytomas, 15 were men and 8 were women, and their ages ranged from 42 to 81 years (mean, 64 years). The gross appearance of renal oncocytomas was characteristically homogeneous tan-brown, with variable scarring, without areas of large hemorrhage, and with no apparent necrosis.

Regional DNA content heterogeneity in colonic adenocarcinoma: prognostic significance in patients with liver metastases.

We retrospectively examined by flow cytometry the DNA ploidy pattern in tissue blocks from 25 primary colon adenocarcinomas and their lymph node and liver metastases. Intratumoral heterogeneity was present in 22% of primary tumors and 21% of metastatic liver deposits. Intertumoral heterogeneity, measured between the primary tumor and its lymph node and liver metastases, was 0% and 20%, respectively.

DNA ploidy in testicular germ cell neoplasms. Histogenetic and clinical implications.

Flow cytometry was used to determine the DNA ploidy pattern of 148 testicular germ cell neoplasms (seminomas and nonseminomas in pure and mixed histologic phenotypes) and in situ carcinoma (CIS) adjacent to these tumors. The great majority (96.0%) manifested aneuploid DNA contents with minimal intratumoral heterogeneity (2.
