Human papillomavirus (HPV) cofactors for cervical cancer include smoking, multiparity, and oral contraceptive use, but their mechanisms of action are not fully understood. It is also unknown whether cofactors vary by HPV genotypes. The Study to Understand Cervical Cancer Early Endpoints and Determinants (SUCCEED) is a cross-sectional study comprising women(More)
OBJECTIVE Fatigue is the most common and often the most bothersome complaint of individuals who are treated for cancer. One intervention now commonly suggested to treat fatigue is the use of psychostimulant medication. Early studies indicate some success in individuals with a mixed cancer diagnoses. This study evaluates the effect of methylphenidate on(More)
Gravity alteration (micro- and hypergravity) is known to influence cell functions. As guanosine 3',5'-cyclic monophosphate (cGMP) plays an important role in human melanocyte functions and different guanylyl cyclase isoforms are responsible for cGMP synthesis in human non-metastatic and metastatic melanoma cells, we investigated the effects of hypergravity(More)
Guanosine 3',5'-cyclic monophosphate (cyclic GMP) is a major second messenger molecule, that is believed to play a role in various physiological and pathophysiological processes. Here we report that hypergravity induces differential effects on cyclic GMP turnover in melanocytic cells. Nonmetastatic melanoma cells responded to long-time exposure (24 h) of(More)
