The News & Observer, Raleigh, NC Thad Ogburn Features Editor togburn newsobserver : newsobserver lifestyles arts entertainment monet We created a print and online special section about a Claude Monet exhibit that was coming to the N.C. Museum of Art. Our "Team Monet" made up of features reporters, editors, photographer and designer ; produced a 12-page section for print. We sent a reporter and photographer to Giverny to explore Monet's world. We broke down one of Monet's paintings in a graphic, explaining his style. We talked about how he influenced other artists, and how Monet references appear in pop culture from "Clueless" to "Seinfeld." Online included slide shows of Monet's work and the great work of our photographer, and a "color like Monet" interactive element.

Knowledge about the intracellular localization of the ubiquinone synthesizing enzymes is scant. They are believed to be membranebound or membrane associated [56]. It is thought that ubiquinone synthesis in cells of higher eukaryotes reflects the yeast pathway. In plant cells, the precise localization of this biosynthetic pathway is a matter of controversy.

Alternatively, the apparent ligand displacement observed might result in the disruption of the quinone binding site being a secondary effect, i.e., whichever residue replaces SdhC H84L may in fact be essential for ubiquinone binding and oxidation. Azido-quinones have been used to label the SdhC subunit of SQR and have implicated Ser-27 and Arg-31 of SdhC as being part of a quinone binding site in the enzyme 16 ; . Although the primary sequence of the membrane anchor subunits of complex II's are not highly conserved, the available structures and models 11, 12, 20, ; all suggest a very similar transmembrane topology. In two subunit membrane anchors, like E. coli SQR, this would place SdhC His84 in helix II on the cytoplasmic membrane face and on the opposite side of a pocket from SdhC Ser27 and SdhC Arg31 as previously suggested 16 ; . The structure of QFR from E. coli shows two quinone binding pockets on the opposite side of the membrane 11 ; and SdhC His84 would be localized near the Qp quinone proximal ; binding site. PCP perturbs the heme environment in E. coli SQR similar to that seen with HQNO in B. subtilis SQR and it has been suggested for B. subtilis SQR that the cytochrome participates in binding and stabilization of the semiquinone generated during electron transfer in the enzyme 39 ; . The semiquinone radical attributed to the Qp site demonstrates rapid relaxation behavior during EPR analysis and this has been attributed to a 23.

Transfer from QA to QB Our result is easily explained if the distal position is not a stable binding position on the timescale 1 ; 1 ; of generation kAB ; and decay kAB ; of the P QB state. That is, the motion of neutral ubiquinone from the distal position to the proximal position is not reversible on the timescale of our pumpprobe experiment, which is approximately 6 s from one laser pulse to the next with an intervening dark image collected ; . Even if a certain amount of RCs in the crystal occupied the distal binding site, they would move to the proximal position upon the first laser flash, and remain thereafter in the proximal position. However, several other effects may also explain the discrepancy between our result obtained from RC of B. viridis and those obtained from RC of R. sphaeroides, such as sequence differences between the two species for example residues L209 and L213 ; and the differing pH and ionic strength of the mother liquor in the crystallographic studies. We propose a model for the first electron transfer to QB that accounts for the observation of a single binding site for ubiquinone in Fourier transform IR difference studies 41, 42 ; , the dependence of ubiquinone position on the protonation or position of ionizable residues within the QB pocket, as suggested by simulations 22, 23, 4446 ; , and the observed distal binding of ubiquinone in the dark 1618, 21 ; . The distal binding site is a metastable binding site for neutral ubiquinone, but it does not correspond to a conformational gate in the reaction. Rather, it is a site that becomes populated during longer periods of dark adaption, such as those that occur during x-ray data collection of the charge-neutral state. Equilibration between the distal and proximal position occurs through dissociation to the solvent, or perhaps by means of an intermediate binding position, such as that observed in simulations in B. viridis 23 ; in which the quinone headgroup is free to rotate with respect to the isoprenyl tail. Upon illumination, an electron arrives at QA. The proximal position is the only active position for electron transfer, as originally suggested 16 ; . The actual conformational gate involves the response of ionizable residues near the QB pocket to the charge at QA, or to the movement of the electron to QB, and may be coupled to proton uptake as concluded in a recent Fourier transform IR study 43 ; . Once QB becomes a semiquinone, it is tightly bound in the proximal position, in agreement with the light structures from freeze-trapping studies 1618 ; , where it is stabilized by additional electrostatic or hydrogenbonding interactions due to the proton uptake by surrounding residues. Meanwhile, ubiquinone is still free to exchange with the solvent or intermediate site, and so the equilibrium shifts to and vaniqa.
Other explanations These analyses also provide an opportunity to test some of the other hypotheses that have been proposed to explain the decline in health in eastern Europe.17 These include impoverishment, environmental pollution, deterioration in health services, and psychosocial stress arising from the pace of change. Impoverishment--The finding that the greatest declines in life expectancy are in those regions that were the wealthiest in 1990 and have subsequently experienced the smallest declines in household income is contrary to the suggestion that the fall in life expectancy can be attributed to impoverishment. A possible explanation is that regions with high average incomes are also characterised by other features that are responsible for the decline in life expectancy, but we cannot explore this further with the data available to us. It is well known, for example, that in Russia higher salaries were used to compensate for hard manual work or for difficult climatic conditions so called regional coefficients ; . We have excluded Siberia, however, which contains most of the regions so affected, although the same peculiar pattern is characteristic of some regions in the north of European Russia with predominantly primary industries mining, oil and gas, timber, etc ; . Although this issue requires further elucidation, obviously it is not sufficient to depend solely on economic growth to bring about an improvement in health. Environment and health services--Neither the causes of death contributing to the decline nor the geographical distribution are consistent with a causal role for environmental pollution, and this has been declining anyway because of the collapse of much heavy industry. Although there can be little doubt that the health service has suffered in many ways since the break up of the Soviet Union, 18 the age groups affected most are those with least contact with health services, with people dying of causes that are relatively insensitive to medical care. Pace of change--The many benefits that were associated with work in certain enterprises in the Soviet bloc, such as access to better health care or housing, means that employment has a rather different social meaning from that in the West.19 Consequently, change of employment in Russia could be expected to be especially traumatic. This analysis supports the argument that the rapid pace of change has been an important factor in increasing mortality, with those of working age facing the greatest psychological pressures during the transition to a market economy. Although the youngest and the oldest may have suffered more from material deprivation, they may have been less affected psychologically. Alcohol--Although this analysis focuses primarily on the underlying rather than the proximal reasons for the decline in life expectancy, it is important to note that the analyses by cause of death strongly support the argument that alcohol has played a major part in the decline in life expectancy in Russia4 and show that conditions associated with alcohol consumption, such as accidents, have been even more important in explaining regional differences. The link between accidents and alcohol is well established in many countries but it is also important to note that, in the context of the very high levels of alcohol consumption seen in Russia, 20 there is now an emerging body of evidence that a substantial proportion of cardiovascular deaths, especially among.

Where he lives, returning to Mt. Sinai for blood draws and to receive blood products like platelets. His leukemia went into remission. "In June I went back to work, " he says, finessing the time and effort it took to recover from the high-dose treatment. Again he seemed to be riding high. Another three months passed without a problem. At the end of September Mark got married.Then, just when he was beginning his new life with his bride, when he returned from his honeymoon, he discovered he had relapsed. The leukemia had come back. Mark was readmitted to Mt. Sinai for more chemotherapy. But once a person has had chemotherapy and it hasn't produced a permanent cure, doctors are reluctant to continue it.They recommended high doses of chemotherapy followed by a bone marrow transplant. Again Dr. Waxman stepped in to help. Following treatment at Mt. Sinai, Mark decided to go to Seattle, to the Fred Hutchinson Cancer Research Center, where bone marrow transplant was pioneered.
Of the developing countries, where educational needs are greatest. T h e conditions that educational television must meet must once more be stressed in order to shatter the illusion that it can provide a cheap solution to the developing countries' educational problems. Everyone feels that it is not enough to broadcast programmes, no matter h o w good, regardless of the educational standards of the target audience or of the reactions and environment which will m a k break their impact--as is confirmed by every serious experiment. It is realized everywhere that the needs, knowledge and motivation of the target audience mustfirstbe studied. Similarly, an audience network must be established, and its quality is more important to the success of operations than is that of the television programmes themselves. Again, television is often no more than the centre-piece of a 'multimedia' system. Radio, for instance, can correct the unwieldiness of television: while television programmes must generally be prepared well in advance and are very costly, radio programmes can be improvised quickly and more cheaply in response to questions and to recapitulate points which have been misunderstood. In short, there is and can be no genuine educational television which merely puts out courses, even good ones, at fixed times. Television is only a cog in a machine, a machine that makes it work and without which it is nothing but a voice crying in the wilderness or, worse, an instrument that widens cultural gaps. At this point in the argument, the two dominant tendencies in modern teaching practice should be recalled: thefirstis the trend towards m a x rationalization, in which education becomes a technique teaching by objective, programmed instruction, etc. ; , while the second emphasizes individual motivations nondirective teaching, freedom to learn, etc. ; . Both reject the massive use of broadcasting techniques to s w entire regions with educational programmes, m u c h vast areas are sprayed with fertilizers while the comparison is left unspoken, such projects are often spelled out: doubters are referred to the m a n and ventavis and ubiquinone.

Ndividuals with a genetic predisposition to pemphigus will develop the disease only when one or more additional factors are present. The nature of these factors is as yet unknown, but our starting point was that certain drugs penicillamine, captopril, and rifampicin ; are recognized as such factors. Since some nutrients have chemical compositions similar to these known causative drugs, these nutrients may act similarly and, therefore, nutritional factors should also be suspected. As when drugs are involved, elimination of the inciting ingredients may be crucial for management of the disease. This article discusses the possible role of nutritional ingredients in the disease process of pemphigus, including fruit, leaves, roots, seeds, and even water. Possible causative candidates are thiol, thiocyanate, phenols, and tannins. Arch Dermatol. 1998; 134: 1406-1410.

The presence and absence of light. Antimycin A, which also blocks the mitochondrial oxidation of ubiquinol, did not inhibit mitochondrial peroxidation. Electron Transport-linked Inhibition of Peroxidation--The next experiments provided ubiquinol-6 for the inhibition of photooxidation of mitochondrial lipid, by the enzymatic reduction of exogenous ubiquinone-6. ?-Hydroxybutyrate was chosen as the substrate for mitochondrial electron transport because it was found to have less effect than succinate or NADH on the rate of lipid peroxidation. Similarly, antimycin A was used to block electron transport and prevent oxidation of ubiquinol because, unlike cyanide, it does not affect lipid peroxidation. Fig. 3 shows that ubiquinol thus formed substantially inhibited peroxidation of mitochondrial lipid. Controls in which there was no ubiquinone, or in which ubiquinone was not reduced to ubiquinol, showed little or no inhibition of peroxidation. Exogenous ubiquinone-6 was much less effective than the quinol in stabilizing lipid.
This study highlights the phenotypic variation in patients with DOA from British families. Although the defective gene in DOA is unknown, the families described show linkage to DNA markers in the chromosome 3q28qter region.21, 33, 34 The clinical heterogeneity seen in this study indicates a highly variable expression of the OPA1 gene. The observed phenotypic variation may have a number of explanations, including allelic heterogeneity, change in disease severity with age, and the effects of other modifying genetic or environmental factors. Both intrafamilial and interfamilial phenotypic variation is seen. Some of the interfamilial variation could result from the effect of different mutations, which can be investigated once the gene is isolated, or from different age structures within families. Intrafamilial variation may result from many factors, among them, but not exclusively, age. Even patients of similar age from the same family can show considerable clinical variation. Such phenotypic heterogeneity is not unusual in autosomal dominant disease. The reasons for it are unknown but may include the modifying effects of other genes involved in retinal and ganglion cell development, the genetic background of the individual, or physiological and environmental factors. Optic disc abnormalities are seen in the vast majority of patients. Best color vision and least field loss was present in patients with the least degree of clinical optic atrophy and ursinus.

Recruitment: CysLTs facilitate eosinophil recruitment. Leukocyte rolling is a prerequisite for vascular adhesion and subsequent migration into inflammatory tissues.98 The CysLT LTD4 induces P-selectin dependent increases of leukocyte rolling flux and a reduction in leukocyte rolling velocity.98 CysLTs also increase eosinophil adhesion by up-regulating 2integrin expression in eosinophils Fig 8 ; 99, 100 and stimulate vascular endothelial cells to produce PAF, a phospholipid known to increase leukocyte adhesion by activating 2-integrin.98 Finally, CysLTs are chemoattractants that induce eosinophil migration Fig 8 ; .99, 101 Conversely, LTRAs significantly inhibit both the up-regulation of adhesion molecule expression and eosinophil chemotaxis.99, 100 Apoptosis: Once eosinophils migrate into the inflammatory site, CysLTs prolong their survival, contributing to maintenance of the inflammatory reaction.

| Like to point out that the treatment with lipopolysaccharide used as a surrogate for sepsis in this elegant experimental series represents an approach focused on direct induction of inducible NO synthetase and elevation of cytokine levels. Cecal ligation and perforation, in contrast, involve a more complex pathophysiological scenario with an upregulation and activation of multiple inflammatory mediators, thus likely emulating the septic disease encountered in patients more closely for review, see Deitch et al3 ; . This also is reflected by the pronounced hemodynamic dysregulation documented in our model. Furthermore, sepsis was considerably less severe in the model reported by Ando et al, with a survival rate 70% in the untreated group at 36 hours, compared with 10% in our study. In light of these significant differences in methodology, it is all the more promising that statins proved to be beneficial in both models. We are aware of the encouraging retrospective bacteremia study by Liappis et al.4 However, bacteremia does not constitute sepsis see consensus criteria for sepsis5 ; and thus does not necessarily imply that the patient was actually suffering from sepsis, including all its hemodynamic and other implications. We therefore continue to believe that retrospective studies on the use of statins and their benefit quo ad vitam in patients afflicted by sepsis could indeed facilitate prospective trials, and we join Dr Stamm in hoping that further investigations in this promising field are stimulated and eventually will benefit patients.

The present results characterize SL65.0155 as a potent and selective ligand for the 5-HT4 receptor that, in common with several other 5-HT4 compounds, shows robust cognitionenhancing activity across a range of tasks in rodents. This activity was comparable in magnitude to that seen with acetylcholinesterase inhibitors, currently the only class of compound available for the symptomatic treatment of Alzheimer's disease, but was maintained over a much broader dose range. In functional tests, SL65.0155 behaved as a competitive antagonist when evaluated in the rat esophagus and guinea pig ileum preparations but demonstrated a broader range of functional interactions with the 5-HT4 receptor when studied against individual 5-HT4 receptor splice variants. This activity ranged from inverse agonism at the 5-HT4 a ; isoform to partial agonist activity 43 48% of the maximal activity of 5-HT ; at the 5-HT4 b ; and 5-HT4 e ; isoforms see below for further discussion ; . Thus, unlike other 5-HT4 compounds that have demonstrated cognition-enhancing activity, SL65.0155 demonstrated much less intrinsic activity. Compounds such as BIMU-1, BIMU-8, and RS 67333 all show moderate to marked efficacy in comparable in vitro preparations, ranging from 50 to 90% of that obtained with 5-HT Eglen et al., 1995; Mialet et al., 2000a ; , increasing the likelihood that they will show side effects. Preclinical studies with 5-HT4 compounds and clinical experience with compounds possessing 5-HT4 agonist activity such as cisapride ; suggest a propensity to induce tachycardia, increased gastrointestinal activity, and urinary incontinence. SL65.0155 clearly lacks cardiovascular and gastrointestinal effects, consistent with its antagonist activity in isolated peripheral tissues. The data presented here therefore not only demonstrate that SL65.0155 is an effective cognition enhancer with a novel mechanism of action but also suggest that it will have a better clinical side effect profile than currently available treatments for memory deficits. Given that the literature supports a role for agonist effects at the 5-HT4 receptor in mediating procognitive effects see Introduction ; and that the effect of SL65.0155 in the object.

Chronic ethanol feeding in rats selectively depletes liver mitochondrial GSH without altering the cystolic GSH pool Hirano et al., 1992 ; . The likely mechanism is decreased mitochondrial inner membrane fluidity, which results in decreased importation of cytosolic GSH Colell et al., 1997 ; . Results from our laboratory have demonstrated that selective depletion of mitochondrial GSH caused by chronic ethanol feeding contributes to the enhanced APAP toxicity Zhao et al., 2002 ; . The combination of both CYP2E1 induction and selective depletion of mitochondrial GSH may largely explain the unusually high susceptibility to hepatic damage in alcohol abusers claimed by Zimmerman and Maddrey 1995 ; . Significant depletion of mitochondrial GSH seems to occur only after more than 3 weeks of ethanol feeding Hirano et al., 1992; Zhao et al., 2002 ; . It is not known whether depletion of mitochondrial GSH requires a high ethanol dose, nor is it known how quickly the effect reverses after ethanol is removed from the diet. In this study, we took advantage of the rat as a model of both human alcoholic liver disease and APAP hepatotoxicity to evaluate the effect of ethanol dose and ethanol withdrawal on the depletion of mitochondrial GSH and APAP toxicity Mitchell et al., 1973; Lieber et al., 1989.
