The peripheral blood of the animals that received transplants was biotinylated, and the amount of biotin that remained over time was measured.15 This experiment Figure 5A-B ; showed that, in keeping with the chimeric nature of the animals that received transplants, there is a biphasic shape to the biotinylation survival curves, having both a short component from the sickle RBCs ; and a long component from the donor RBCs ; . Given this mixture of 2 separate RBC populations, a single RBC half-life could not be directly interpolated from the chimeric biotinylation curves. However, the measurement of the time required for half the original biotin signal to disappear referred to here as the biotinylation50 time ; did give important information about the correction of peripheral blood hemolytic anemia in the chimeric animals. This analysis showed that mice with low levels of donor hemoglobin Hb ; had composite biotinylation50 times resembling sickle mice that did not receive transplants, whereas a progressive increase in this measurement occurred with increasing levels of donor Hb Figure 5A-B ; . This correlation between peripheral RBC chimerism and RBC biotinylation50 time gives direct support for the hypothesis that enhanced survival of healthy RBCs in the peripheral blood is the cause of the enrichment in peripheral RBC over WBC chimerism. Furthermore, most of the mice that received transplants had peripheral RBC WBC chimerism ratios of approximately 20 or less the ratio of the differential survival of healthy and sickle RBCs as shown in Figure 5 and in our previous work7 ; , indicating that the differential peripheral blood survival of donor over sickle RBCs is sufficient to explain the enrichment in RBC versus WBC chimerism observed in the chimeric mice.
Keywords: blaOXA-1, blaOXA-30, b-lactamases * Corresponding author. Tel: + 1-204-789-2133; Fax: + 1-204-7895020; E-mail: Michael mulvey phac-aspc.gc Sir, Recently while perusing articles on the Journal of Antimicrobial Chemotherapy Advance Access web page : jac. oxfordjournals papbyrecent.dtl ; the correspondence from Mendon a et al., 1 `CTX-M-15, OXA-30 and TEM-1-producing c Escherichia coli in two Portuguese regions', caught our attention. The authors point out that apart from their report, this particular combination of b-lactamase genes had only been reported in c Salmonella strains from Senegal.2 Mendon a et al. also referenced reports of the combination of blaCTX-M-15, blaOXA-1 and blaTEM-1 having been found in strains from the UK, India and Canada. When blaOXA-30 was initially characterized in 2000 a single amino acid difference was noted between the presumptive enzyme and OXA-1, and hence the authors correctly named it OXA-30.3, 4 OXA-30 contained a Gly-128 whereas OXA-1 contained an Arg-128.3, 4 In Canada it was the plasmid pC15-1a characterized in our lab that contained the blaCTX-M-15, blaOXA-1 and blaTEM-1 combination.5 During our characterization of pC15-1a, BLAST searches of the GenBank database with our sequence data revealed the presence of the blaCTX-M-15, blaOXA-30 and blaTEM-1 genes. When we received the editor's and reviewer's responses to the original manuscript describing the characterization of pC15-1a, one reviewer pointed out that OXA-30 is in fact identical to OXA-1 and referred us to Sun et al.6 published in 2003 ; in which the crystallographic structure of OXA-1 was presented. Admittedly, we had no knowledge of that report. In that work the data did not support the presence of Arg-128 and they reported that the authors of the original report on the sequence of blaOXA-1 confirmed a sequence error in the originally published DNA sequence, such that OXA-1 did in fact contain a Gly-128.6 The crystallographic data were generated from an enzyme produced from a cloned blaOXA-1 gene from plasmid RGN238 which was also the source of the original DNA sequence data; hence, together these data confirm a Gly-128 in OXA-1.4, 6 Thus, the originally published sequence of blaOXA-30 was in fact blaOXA-1 though Siu et al.3 could not have known this at the time. We note that of a total of 11 entries in the GenBank database containing blaOXA-1, blaOXA-1-like or blaOXA-30, the cognate enzymes are all identical and contain a Gly-128 except for the originally published OXA-1 sequence accession no. J02967 ; , which surprisingly has not been updated. Thus, even if the genes contain sequence variations, which we did not check for, they are all blaOXA-1 variants. The appearance in the literature of two enzyme names for an identical enzyme is confusing and we encourage all authors to update their GenBank submissions that refer to blaOXA-30. In this way, future occurrences of OXA-1 will be correctly identified. Undoubtedly, as was the case for us, many molecular biologists may not regularly read papers concerned with the crystallographic structure of proteins, and as far as we can discern the paper by Sun et al. is the only source in which the correct sequence of blaOXA-1 is referenced.

Mesalazine 24 g daily or balsalazide 6.75 g daily are effective first line therapy for mild to moderately active disease grade A ; . Olsalazine 1.53 g daily has a higher incidence of diarrhoea in pancolitis grade A ; and is best for patients with left sided disease, or intolerance of other 5-ASA. Sulphasalazine has a higher incidence of side effects compared with newer 5-ASA drugs grade A ; . Selected patients, such as those with a reactive arthropathy, may benefit. Prednisolone 40 mg daily is appropriate for patients in whom a prompt response is required, or those with mild to moderately active disease, in whom mesalazine in appropriate dose has been unsuccessful grade B ; . Prednisolone should be reduced gradually according to severity and patient response, generally over 8 weeks. More rapid reduction is associated with early relapse grade C ; . Long term treatment with steroids is undesirable. Patients with chronic active steroid dependent disease should be treated with azathioprine 1.52.5 mg kg day or mercaptopurine 0.751.5 mg kg day grade A ; . Topical agents either steroids or mesalazine ; may be added to the above agents. Although they are unlikely to be effective alone, they may benefit some patients with troublesome rectal symptoms grade B ; . Ciclosporin may be effective for severe, steroid refractory colitis grade A ; see section 5.3.

Vertical and horizontal transport of radionuclides The parameter values used in the equations describing the vertical and horizontal transport of radionuclides are shown in Table 6-2. The depth of the top soil the layer where most active roots are located ; was assumed to vary between 0.4 and 0.5 m. The depth of the deep soil soil layer from the root zone to the groundwater table ; was estimated to vary between 0 and 0.7 m with a mean value of 0.4 m by subtracting the assumed depth of the top soil from the distance from the soil surface to the groundwater table height of the groundwater table ; obtained from field data. The minimum value of the height of the groundwater table 0.9 m ; was estimated from measurements in boreholes drilled in April and the maximum value 1.6 m ; from measurements in boreholes drilled in August. An annual average based on these calculations of 1.3 m was used. The depth of the groundwater table was obtained by subtracting the total soil depth from the height of the groundwater table. Runoff was obtained from estimations see calculation of discharge in each cell in a rasterized Eckarfjrden catchments ; of the specific runoff in the area 6.5 103 m3 km2 s ; . Data on soil porosity was obtained as follows: texture composition of about 40 soil profiles in combination with a rough classification of the soil were compared to similar soils for which data are available in the database of the CoupModel. The outcome of that investigation lead to a set of values for different soil-types and depths. Based on these values an average value of 0.45 was assumed as best estimate for the two soil layers and a value of 0.25 for the saturated zone and mesna.

A study of 1, 846 school children froim a community in Colorado with a population of 12, 000 was undertaken in order to investigate the hypothesis that a single-lead electrocardiogram showing a pattern of right ventricular hypertrophy would serve as a screening mechanism to pick up any congenital heart disease that resulted in right ventricular hypertrophy. It was hoped that this screening would pick up cases of atrial septal defect, pulmonic stenosis, tetralogy of Fallot, and patent ductus arteriosis with reverse.

2002 ; , rat kidney Shihab et al., 2004 ; , and prostate cancer cells van der Poel, 2004 ; . Because these experiments were not conducted using either hepatocytes or HSC, we conclude that the effect of rapamycin in the liver might differ from the effect in other tissues. The most dramatic effect was seen in the message of CTGF, a downstream mediator of TGF- Moussad and Brigstock, 2000 ; involved in experimental and human liver cirrhosis Paradis et al., 1999; Williams et al., 2000 ; . CTGF is produced in HSC Paradis et al., 1999; Williams et al., 2000 ; and proliferating cholangiocytes Sedlaczek et al., 2001 ; . Both cholangiocytes and activated HSC were markedly reduced by rapamycin treatment. Further studies will be needed to delineate which cell type is most responsible for the decrease in fibrogenic cytokines. The hemodynamic changes induced by bile duct ligation in rats are favorably influenced by rapamycin treatment, as shown by a decrease in portal pressure and increase in portal blood flow. Interestingly, hepatic artery blood flow was significantly lower in BDL SIR compared with both BDL CTR and sham rats. An increase in hepatic arterial blood flow is seen in different models of portal hypertension, in particular in BDL owing to the marked ductular proliferation Gross et al., 1987; Van de Casteele et al., 2001 ; . Thus, a reduction in arterial flow in rapamycin treated animals is not unexpected in light of the reduction of ductular proliferation. However, hepatic arterial flow was decreased even compared with the sham-operated rats, suggesting some specific effect of rapamycin on hepatic arterial flow. Stereological analysis has demonstrated inhibition of two expanding cell lines induced by BDL: cholangiocytes and HSC. The antiproliferative activity of rapamycin is well established Hidalgo and Rowinsky, 2000 ; . Rapamycin is thought to affect the cell cycle through inhibition of mTOR by the FKBP12-rapamycin complex, thereby inhibiting the phosphorylation of p70s6k and 4E-BP1, impairment of pRb hyperphosphorylation, and prevention of p27 down- and p21 up-regulation. p27 and p21 belong to the kinase inhibitor.

As the husband of a nurse, your editorial about the doctor of nursing practice DNP ; makes me worry, and not just that I'll hear about it at the dinner table for years to come. Nursing as a profession faces difficulties that are much more fundamental than a few more initials after a nurse's name. There are those who believe that professional nursing is in danger of marginalization, if not outright extinction. Yet, instead of a grass-roots movement to solidify the place of professional nursing in the healthcare firmament, there is discussion about a new doctorate degree for nurses. Many situations and questions leap to my mind, but before I can consider them, I compelled to get past an image of "rearranging deck chairs on the Titanic." If nurses seek a new doctorate in an effort to gain respect from physicians and other healthcare providers, t h ey are not likely to get that respect. Any lack of respect regarding the nursing profession probably isn't based on initials, and therefore adding initials won't address the problem. Changing the perceptions of not only healthcare professionals but also of society takes time, work, and unity of purpose. Until nurses can speak with one voice, until they can provide the data that prove their worth, and until the word "nurse" means similar things to all people, problems of respect and questions about place in the scheme won't be answered. Push to have nurses as professors in medical schools, by all means. Work to show medical students and interns that nurses are professional members of the team, absolutely. Simply making up a new degree in an effort to gain professional respect opens the profession up to charges of, well, making up a new degree in an effort to gain professional respect. Nursing isn't, and never has been, about "bean counting" or making money. Nursing is about patient care, first and foremost, and providing the best possible care should be eve ry nurse's goal. I just don't see how the DNP gets you there. David Blackman Chesapeake, Va.
FUTURE OF WALKER LAKE WILL BE DEBATED AT SUPREME COURT Carson City-- Attorney General Frankie Sue Del Papa's Office will present arguments before The Nevada Supreme Court on Friday, February 9, 2001, at 9: 30am, regarding whether the State of Nevada can reallocate Walker River to help Walker Lake. Del Papa's Office will argue that Nevada's State Water Engineer is not authorized to unilaterally alter the river's water rights, because a federal court in Reno exclusively controls the rights, many of which were created a century ago. Historically, the lake levels at Walker Lake have declined, raising concerns among environmental organizations about the Lake's health. The Walker River flows from the Sierras near Bridgeport, California, through Nevada, ending at Walker Lake. In the 1930s, ownership of water in the Walker River was determined by a federal court, which has controlled water diversions ever since. Last year, Mineral County sued the State of Nevada in the Nevada Supreme Court, asserting the State must cutback long-established Walker River water rights to help the Lake. Mineral County has sought the same relief in the Reno federal court. The Attorney General's Office will argue that Nevada's Legislature never authorized the State Engineer to go back and take water away from people who have relied on the water for a century, and then reallocate it to another use. Del Papa`s Office will also claim that even if the State had that authority, it could not help Walker Lake because the State has no jurisdiction over California water rights, Indian water rights, and federal water rights. "The agricultural economy of Smith and Mason Valleys, as well as many Nevada and California communities along the Walker River, depend on their current uses of Walker River water, " Del Papa said. "This case should be in the federal court. Any solution for Walker Lake requires changes to Weber Reservoir, which is located on an Indian reservation in northern Nevada. The federal court, not the State of Nevada, has authority over that reservoir. Also, the federal court, not the State of Nevada, has authority over other federal water rights and water rights in California. Mineral County's request would force only Nevada water right owners to lose water to help the Lake, and that is simply not fair and just." --more and methadone.
