OBJECTIVE
The aim of this study was to evaluate the role of levodopa/carbidopa as an augmenting agent to improve motor recovery after brain tumor excision.
METHODS
This case report is structured as an n-of-1 style trial. The study patient was an outpatient with residual hemiparesis secondary to
Reactions of closo-1-Me-2-Iodobutyl-1,2-closo-dicarborane, 1-Me-2-I(CH2)4-C2B10H10, with l-dopa methyl ester can produce carboranyl l-dopa methyl esters in 54% yield in the presence of sodium hydroxide. The appended closo-carboranes can be
In this study, an efficient drug delivery system composed of Fe3O4, CaAl layered double hydroxide (LDH) and l-Dopa has been synthesized through hydrogen bonds between l-Dopa and CaAl-LDH encapsulated Fe3O4 nanoparticles
Cancer patients may experience acute or chronic pain caused by tumor infiltration of pain-sensitive structures or related to surgery, radiation, and chemotherapy. Acute bone pain, with or without associated neurologic deficits resulting from tumor metastasis to bone and contiguous neural structures
Levodopa and dopamine are naturally occurring catecholamines with antitumor activity in several experimental tumor systems. Previous studies suggested that their cytotoxic effect was related in part to their inhibitory effect upon DNA polymerase. We have examined the effects of levodopa, dopamine,
Levodopa and dopamine demonstrate significant antitumor activity in several experimental systems. We have prepared the nonneurotoxic dihydroxybenzylamine (DHBA) analogs 2,3-DHBA, 3,4-DHBA, and 2,5-DHBA and the trihydroxy derivatives 2,3,4- and 3,4,5-trihydroxybenzylamine. These analogs demonstrated
Novel antitumor agents related to levodopa and dopamine exhibit a selective and rapid inhibition of DNA synthesis as measured by thymidine incorporation. Our investigations have attempted to determine the biochemical basis of the selective inhibition of tumor cells and in this present study we
A 72-years old man with Parkinson's disease was treated with levodopa for 14 years. A superficial spreading melanoma (Breslow depth 1,8 mm Clark level IV) was diagnosed, developing on the back from a pigment lesion which had present for more than 10 years. Other case reports suggest a relationship
Nanotheranostics (combined diagnosis and therapy) is emerging as an integral part of future therapeutic strategies. However, the development and fabrication of a nanotheranostic module involves multistep processes and always faces formulation challenges. The complexity involved in its multi-step
Treatment with the drug combination of levodopa methylester and benserazide, supplemental ascorbate, and dietary deficiencies of tyrosine and phenylalanine more than doubled the median survival time of female (C57BL/6 X DBA/2)F1 mice bearing B16 melanoma tumors. The mechanism for this antitumor
We report here the single and combined antitumor activity on B16 melanoma in female C57BL/6 X DBA/2F1 mice bearing s.c. tumors of sodium ascorbate, carbidopa-levodopa methyl ester, and dietary phenylalanine and tyrosine deficiency. Groups of 15 mice were fed continuously one of three test diets both
Parkinsonism is a rare neurological complication of cancer treatment. Although individual case reports of this syndrome have been reported, the clinical features and prevalence of this syndrome are unknown. We present 3 patients, encountered over 6 months at one institution, who developed
The main lesion in Parkinson disease (PD) is loss of substantia nigra dopaminergic neurons. Levodopa (L-DOPA) is the most widely used therapy, but it does not arrest disease progression. Some possible contributing factors to the continuing neuronal loss are oxidative stress, including oxidation of
Pituitary tumors were removed transsphenoidally in 32 patients with acromegaly. Ten patients had high prolactin (PL) levels as well as elevated growth hormone (GH) levels. In 24 patients, GH levels were lowered to 5 ng/mL or less and remained low. The PL level was reduced to normal in eight
Background: Although clinically evident and MRI confirmed, basal ganglia involvement, is usual in primary antiphospholipid syndrome, extrapyramidal disorders such as parkinsonism and dystonia are very rare. We were unable to find any report in the literature on dystonia-parkinsonism in patients with
