OBJECTIVE To evaluate the efficacy of carbidopa L-dopa (Sinemet) in reducing left spatial neglect after stroke. DESIGN Case series. SETTING Inpatient neurorehabilitation unit in a regional rehabilitation center. PARTICIPANTS A convenience sample of 4 women with right brain strokes and left neglect. INTERVENTION A trial of carbidopa L-dopa to treat(More)
Light in the UVB spectrum (280-320 nm) induces a number of changes in the epidermis and dermis of mice and humans, resulting in a robust inflammatory response. A standardized black raspberry extract (BRE) has been effective in reducing signaling pathways commonly initiated by inflammatory stimuli. In this study, we determined whether this extract could(More)
Cyclooxygenase-2 (COX-2) and the prostaglandin products generated as a result of COX-2 activity mediate a variety of biological and pathological processes. Scarless healing occurs in fetal skin in the first and second trimesters of development. This scarless healing process is known to proceed without a significant inflammatory response, which appears to be(More)
Chronic exposure to UV light, the primary cause of skin cancer, results in the induction of high levels of cyclooxygenase-2 (COX-2) expression in the skin. The involvement of COX-2 in the carcinogenesis process is mediated by its enzymatic product, prostaglandin E(2) (PGE(2)). PGE(2) has been shown to have a variety of activities that can contribute to(More)
The American Cancer Society reports the incidence of squamous cell carcinoma in males to be thrice the incidence in females. This increased squamous cell carcinoma incidence has been attributed to men accumulating more sun exposure and using less sun protection than women. To date, there have been no controlled studies examining the effect of gender on skin(More)
Prostaglandin E2 (PGE2) upregulation in response to UV light exposure is a significant factor in the development of non-melanoma skin cancer. It is known that PGE2 signals via the E prostanoid receptors, EP1-4, but the role that each receptor plays in skin carcinogenesis is unclear. Immunohistochemical analysis of EP receptor staining in unirradiated and(More)
Ultraviolet B (UVB) light is the major environmental carcinogen contributing to non-melanoma skin cancer (NMSC) development. There are over 3.5 million NMSC diagnoses in two million patients annually, with men having a 3-fold greater incidence of squamous cell carcinoma (SCC) compared with women. Chronic inflammation has been linked to tumorigenesis, with a(More)
Solid organ transplant recipients have a 60-250-fold increased likelihood of developing sunlight-induced squamous cell carcinoma (SCC) compared with the general population. This increased risk is linked to the immunosuppressive drugs taken by these patients to modulate T cell function, thus preventing organ rejection. To determine the importance of T cells(More)
The present studies examined the temporal sequence of inducible nitric oxide synthase (iNOS) gene expression and the cellular sources of iNOS protein and of 3-nitrotyrosine, as a marker of production of nitric oxide-derived reactive nitrogen intermediates during murine multi-stage carcinogenesis. Levels of iNOS mRNA in dorsal skin isolated from(More)
Immunosuppressive therapies allow long-term patient and transplant survival, but are associated with increased development of UV-induced skin cancers, particularly squamous cell carcinomas. The mechanisms by which CsA, MMF, tacrolimus (TAC) or sirolimus (SRL), alone or in dual combinations, influence tumor development and progression are not completely(More)
