It is now well-established that perturbations in the tricarboxylic acid (TCA) cycle play an important role in the metabolic transformation occurring in cancer including that of the prostate. A method for simultaneous qualitative and quantitative analysis of TCA cycle intermediates in body fluids, tissues, and cultured cell lines of human origin was developed using a common C18 reversed-phase co...

Introduction: Pro-inflammatory cytokines, such as IL-1b and TNF- α have been suggested to be involved in the pathophysiology of depression. Tricyclic antidepressants (TCAs) are also thought to influence immune functions and concentrations of cytokines. The aim of this study was to evaluate the status of serum IL-1b and TNF-α in depressed patients who were treated, not treated, or poisoned wit...

An oral dosing of either acetylsalicylic acid (ASA) or taurocholic acid (TCA) to pylorus-ligated rats subjected to water-immersion stress produced severe damage to the gastric musoca in contrast to the irritation observed in non-stressed ones. The irritative activity of ASA or TCA on gastric mucosa under stress was dose-dependent. Stress itself (23 degrees C, 7 hr) did not induce any appreciabl...

Introduction This comment addresses the recently proposed rules for transmission investment and transmission cost allocation (TCA) as offered for the restructured electricity market in New England. The basic theme is that the TCA proposal is both inconsistent with the new market design in New England and not supported by the TCA proposal’s own analysis. Rather, the TCA proposal reflects an earl...

Natural attenuation is an effective and feasible technology for controlling groundwater contamination. This study investigated the potential effectiveness and mechanisms of natural attenuation of 1,1,1-trichloroethane (TCA) contaminants in shallow groundwater in Shanghai by using a column simulation experiment, reactive transport model, and 16S rRNA gene clone library. The results indicated tha...

Available immunomodulatory and conventional steroid treatment options for patients with progressive multiple sclerosis (MS) only provide limited symptomatic benefit. We performed an open trial on the short-term and long-term efficacy and safety of repeated intrathecal application of the sustained release steroid triamcinolone acetonide (TCA) in 36 progressive MS patients. Six TCA administration...

The accuracy of the time compression analysis (TCA) is analyzed by comparison with a numerical solution. Both the standard TCA and a new modified TCA are considered for a power law diffusivity and constant surface flux. As expected, the error of the approximations decreases with increasing power, and the error of the modified TCA is about half the error of the standard TCA. In a second part, th...

BACKGROUND AND PURPOSE Simultaneous traumatic carotid-cavernous fistulas(TCCFs) and traumatic cerebral aneurysms (TCAs) of the internal carotid artery (ICA) are rare. We describe the pitfalls of detecting a TCA before TCCF occlusion and the endovascular management of the TCA and TCCF. METHODS Over 12 years, 156 patients with TCCFs were treated at our institute. In four men (mean age, 34 years...

The purpose of this study was to develop a two-compartment metabolic model of brain metabolism to assess oxidative metabolism from [1-(11)C] acetate radiotracer experiments, using an approach previously applied in (13)C magnetic resonance spectroscopy (MRS), and compared with an one-tissue compartment model previously used in brain [1-(11)C] acetate studies. Compared with (13)C MRS studies, (11...
