Post-mortem studies have demonstrated a substantial loss of nicotinic receptors in Parkinson's disease (PD), which may be at least partially responsible for some of the cognitive, motoric, and behavioral deficits seen in this disorder. Epidemiologic studies have suggested that cigarette smoking is a strong negative risk factor for the development of PD. We(More)
This article reviews the brain localization of calculation disorders (acalculia) beginning with Gall's claim in the early 19th century for a "center" of calculation. A renewed interest in the subject arose around the time of Henschen during the first quarter of the 20th century. A summary of the cases of acalculia since Henschen leads to the conclusion that(More)
OBJECTIVES To identify the presence of lymphatic invasion in primary cutaneous melanoma using monoclonal antibody D2-40, a marker of lymphatic endothelium, and to correlate the presence of lymphatic invasion with other clinicopathologic characteristics of the tumors. DESIGN Retrospective melanoma case series study comparing conventional hematoxylin-eosin(More)
Oestrogen and progesterone receptor (ER and PgR) assay values are frequently used in medical decision-making for breast cancer patients. We have proposed statistical standardization of receptor assay values to improve inter-laboratory comparability, and now report the use of standardized log units (SLU) to investigate the effects of ER and PgR cut-points on(More)
This phase I/II neoadjuvant trial (ClinicalTrials.gov identifier NCT00066443) determined maximally-tolerated doses (MTD), dose-limiting toxicities, response-to-therapy, and explored the role of novel response biomarkers. MA.22 accrued T3N0, any N2 or N3, and T4 breast cancer patients. Treatment was 6 cycles of 3-weekly (Schedule A; N = 47) or 8 cycles of(More)
There has been an increase in research during the past few years on discourse, with particular focus on normal older adults and clinical populations, e.g., aphasic and head-injured patients and patients with Alzheimer's disease. A recent edited book, Discourse Analysis and Applications: Studies in Adult Clinical Populations, reviews some of this work.(More)
