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...

Preeclampsia may affect severely the cerebral circulation leading to impairment of cerebral autoregulation, edema, and ischemia. It is not known whether impaired autoregulation occurs before the clinical onset of preeclampsia, and whether this can predict the occurrence of preeclampsia. Seventy-two women at 25 to 28 weeks of gestation were studied. Control values were derived from 26 nonpregnan...

Metformin and the mitochondrial targeting dichloroacetate (DCA) have recently received attention due to their ability to inhibit anaerobic glycolysis, which renders most cancer cells resistant to apoptosis induction. We observed that Metformin alone exhibited a dose-dependent anti-leukemic activity in both B leukemic cell lines and primary B-chronic lymphocytic leukemia (B-CLL) patients' cells ...

Sodium dichloroacetate (DCA) has been studied as a metabolic cancer therapy since 2007, based on a publication from Bonnet et al demonstrating that DCA can induce apoptosis (programmed cell death) in human breast, lung and brain cancer cells. Classically, the response of cancer to a medical therapy in human research is measured by Response Evaluation Criterial for Solid Tumours definitions, whi...
