Dichloroacetate sodium (DCA) is a nonproprietary drug currently used for treatment of inherited mitochondrial diseases. It was discovered in 2007 that DCA promotes human cancer cell death by a novel mechanism. Soon after this discovery, physicians began using DCA off-label for cancer treatment in a palliative setting. A case report is presented of a 71-year-old male with poorly differentiated c...

This paper presents a novel analysis of cochannel and adjacent channel reuse ratio distributions in DCA microcell systems, and compares the results with conventional FCA macrocell systems. Computer simulations show that DCA systems exhibit significantly closer channel reuse than FCA systems for a significant proportion of terminals. Mathematical analysis is used to show that this is a fundament...

Spontaneous apoptosis in hepatocytes of male B6C3F1 mice that received dichloroacetic acid (DCA) in their drinking water for 5-30 days (28-58 days of life) was examined as part of ongoing studies to determine the molecular basis of the hepatocarcinogenicity of this nongenotoxic water chlorination by-product. DCA at 0.5 and 5.0 g/liter, significantly reduced apoptosis relative to untreated contr...

A 60-kDa, salt-inducible, internally duplicated alpha-type carbonic anhydrase (Dca) is associated with the plasma membrane of the extremely salt-tolerant, unicellular, green alga Dunaliella salina. Unlike other carbonic anhydrases, Dca remains active over a very broad range of salinities (0-4M NaCl), thus representing a novel type of extremely halotolerant enzyme. To elucidate the structural pr...

To investigate potential dosimetric benefits and treatment efficiency of dynamic conformal arc therapy (DCA), intensity modulated radiation therapy (IMRT), and double partial arcs Rapidarc (RA) techniques in the treatment of early-stage peripheral lung cancer using stereotactic body radiotherapy (SBRT) with flattening filter free (FFF) beams. Twenty early-stage peripheral lung cancer patients w...

BACKGROUND In 2003, the International Liaison Committee on Resuscitation (ILCOR) published the Recommended Guidelines for Uniform Reporting of Data from Drowning: the "Utstein style" ("Utstein Style for Drowning," USFD) to improve the understanding of epidemiology, treatment, and outcome prediction after drowning. AIMS The aim of this study was to compare the characteristics and outcome betwe...

Lactic acidosis is a clinical condition due to accumulation of H(+) ions from lactic acid, characterized by blood lactate levels >5 mM and arterial pH <7.25. In addition to supportive care, treatment usually consists of intravenous NaHCO(3), with a resultant mortality >60%. Dichloroacetate (DCA) is a compound that lowers blood lactate levels under various conditions in both man and laboratory a...

The fungicides vinclozolin and iprodione are widely used in agriculture. These pesticides are dicarboximide fungicides containing the common moiety 3,5-dichloroaniline (3,5-DCA). It has been suggested that low-level exposures to such compounds may be associated with adverse health effects such as endocrine disruption. In this study a method using liquid chromatography/triple quadrupole mass spe...

Dichloroacetate (DCA) is a xenobiotic of interest to both environmental toxicologists and clinicians. The chemical is a product of water chlorination and of the metabolism of various drugs and industrial chemicals. Its accumulation in groundwater and at certain Superfund sites is considered a potential health hazard. However, concern about DCA toxicity is predicated mainly on data obtained in i...

Iturriaga, Rodrigo, and Julio Alcayaga. Effects of CO2HCO3 2 on catecholamine efflux from cat carotid body. J. Appl. Physiol. 84(1): 60–68, 1998.—Using a chronoamperometric technique with carbon-fiber microelectrodes and neural recordings, we simultaneously measured the effects of the following procedures on catecholamine efflux (DCA) and frequency of chemosensory discharges (fx) from superfuse...
