The international reputation of the Faculty continues to be well served through its various exchange programs, including the Cultural Production project supported by Human Resources Development Canada see Partnerships, above ; . Several Fine Arts faculty members are serving in an executive capacity in international professional associations in their fields, among them the World Dance Association and the International Organization of Scenographers, Technicians and Architects of Theatre. Locally, the Faculty's commitment to ethnocultural diversity gave rise to a new summer outreach program developed collaboratively with Toronto's Harbourfront Centre, offering intensive, noncredit cultural workshops to the public in conjunction with Harbourfront's flagship community arts festival, World's Fare. In 2002- 03 the Faculty of Fine Arts made a concerted effort to improve its research environment and to increase the number of research applications submitted by faculty members to external granting agencies, especially SSHRC. Initial steps taken include the establishment of a Faculty Research Committee, the development of a framework to introduce Research Release Grants, and the development of a position for a Faculty-based Research Officer. Several Fine Arts faculty have joined the Culture and Entertainment Working Group in the Office of the Vice-President, Research and Innovation. Throughout the year, Fine Arts worked pro-actively with York's restructured Communications and Media Relations divisions to integrate and support the University's newly defined brand and visual identity program. The Faculty continued to invest considerable effort in internal and external public relations activities to increase awareness of the many accomplishments of Fine Arts faculty and students, with positive results. Special honours and accomplishments in 20022003 include: Film & Video professor Janine Marchessault was awarded a Canada Research Chair in Art, Digital Media and Globalization to study new media artists and their collaborations with institutions and cultural industries. Based on their winning proposal, third-year design students Graham Huber, Peter Hui and Gigi Lui were commissioned to design both the personal patch for Canadian Space Agency astronaut Steve MacLean and the patch to be worn by all the crew members of NASA's Space Shuttle mission STS-115 12A.
Effect of exposure of tumor cells to H2O2 or heat shock on B7-1 and B7-2 surface expression We have previously shown that in vitro exposure of MOPC-315 or P815 tumor cells to L-PAM, -irradiation, or mitomycin C leads to selective up-regulation of B7-1 surface expression, and that this up-regulation of B7-1 expression occurs at the transcriptional level 15 ; . Because reactive oxygen species were reported to be induced following exposure of cells to these anticancer modalities 26 29 ; , and to be important mediators of gene activation 20, 26, 28 ; , experiments were undertaken to determine whether exposure of MOPC-315 or P815 tumor cells to H2O2 can also lead to selective up-regulation of B7-1 surface expression. Accordingly, MOPC315 or P815 tumor cells were exposed in vitro for 15 min to H2O2 and then cultured for an additional 2224 h before B7-1 or B7-2 surface expression was assessed. Because similar results were obtained with MOPC-315 and P815 tumor cells, we elected to present the data obtained with P815 tumor cells because untreated P815 tumor cells, unlike untreated MOPC-315 tumor cells, are negative not only for B7-1surface expression but also for B7-2 surface expression 15, 18 ; . As seen in Fig. 1A, in vitro exposure of P815 tumor cells to H2O2 at a concentration ranging from 0.03 to 1.0 mM led to up-regulated B7-1 surface expression. The same preparation of P815 tumor cells remained negative for B7-2 surface expression even when exposed to 1.0 mM H2O2 Fig. 1B ; . Thus, H2O2 mimics the effect of L-PAM, -irradiation, and mitomycin C on B7-1 surface expression on tumor cells. Experiments were next conducted to determine whether exposure of P815 tumor cells to a different type of stress, heat shock, would also result in selective up-regulation of B7-1 surface expression. For this purpose P815 tumor cells were incubated for 2 h at 42C and then transferred to 37C for an additional 2224 h, before B7-1 and B7-2 surface expression was assessed. As a reference point, the same batch of P815 tumor cells was exposed in vitro to L-PAM or H2O2. As seen in Fig. 2, although exposure of P815 tumor cells to L-PAM or H2O2 led to up-regulated B7-1 surface expression, heat shock treatment did not lead to elevated B7-1 surface expression. Thus, not all types of stress lead to elevated B7-1 surface expression on P815 tumor cells.

AJP-Gastrointest Liver Physiol VOL. In a prospective, comparative evaluation of therapy in advanced gastrointestinal carcinoma with 5-fluorouracil, mitomycin C, and 1, 3-bis- 2-chlorethyl ; -l-nitrosourea used alone, in double combination, and in triple combination, 215 adults with proved gastrointestinal adenocarcinoma were randomly assigned to one of seven possible treatment programs. Dosages and schedules were determined from the results of a pilot program to allow comparable toxicity when administered over a comparable time between the programs. Objective evaluation of the overall results at 8 weeks indicates that the effectiveness of the drug combinations did not exceed that of the component drugs used alone. Combined 5-fluorouracil and 1, 3-bis- 2-chlorethyl ; -l-nitrosourea therapy might be preferentially effective for gastric and pancreatic carcinoma, but further study will be required for more definitive evaluation of this possibility. 3.

Ing exercise may be reliant on a much greater IGF-I response to GH than that required for improvements in VeT and LBM. The a-vO2 difference at a VO2 of 1250 ml min significantly increased after 1 month of rhGH treatment; however, the change compared with that after placebo treatment was not statistically significant. The possibility exists that the sample size n 12 ; was inadequate, perhaps rendering the study not powerful or sensitive enough to show a difference. Therefore, the possibility of a false negative result or type II error with respect to a-vO2 difference cannot be ruled out. Retrospective power analysis revealed a statistical power less than 0.80. In the present study cardiorespiratory exercise testing, and the expired gas analyses thereof, elucidated reduced extraction and utilization of oxygen by peripheral muscle tissue in patients with HIV-associated wasting. GH treatment transiently corrected this, subsequently improving the Q-VO2 relationship in our patients. Therefore, the beneficial effect of GH on physiological performance attests to its potential ergogenicity in patients with HIV-associated wasting despite the use of antiretroviral therapy. RESULTS Creation of a mitN Deletion Mutant--A mitN deletion mutant DHS5373 ; was created from the S. lavendulae mitM insertional mutant strain MM106 29 ; . The mutants were screened for phenotype change from kanamycin, apramycin double resistant to double sensitive, and confirmed by the correct band shift with Southern blot hybridization data not shown ; . DHS5373 had identical growth characteristics as wildtype S.-lavendulae. The two-dimensional TLC analysis of the crude extract showed production of MC 3 ; , and a new purple-pigmented compound. Interestingly, MB 8 ; , which is typically produced by the S. lavendulae wild-type strain cultured under the same growth conditions, was not observed in the extract of DHS5373. Isolation and Structure Elucidation of a New Mitomycin Intermediate--To identify the structure of the accumulated intermediate, DHS5373 was fermented in 6 liters of Nishikohri medium 33 ; . After 96 h, the fermentation broth was centrifuged, and the supernatant was extracted twice with ethyl acetate. The organic extract was combined and dried in vacuo to yield a brown oil 652 mg ; . The crude extract was subjected to gel permeation LH-20 ; column chromatography using methanol as the eluent. MA 1 ; eluted first followed by the newly accumulated intermediate 9-epi-MC 10 ; and MC 3 ; , respectively. The fractions that contained compound 9-epi-MC were combined, concentrated, and applied to a silica gel column chromatography followed by reverse phase HPLC to afford 0.65 mg liter 9-epi-MC. For the MA- and MC-containing fractions, the purification was performed in a similar fashion to provide MA 0.23 mg liter and modafinil.

Of attachment to the cell Table 5 ; . Phages B3, D3, E79, F116, G101, PB1, and P04 contain DNA, PP7 and 7S contain RNA, whereas the composition of C5 and M6 remains to be determined 6, 7, 8, ; . Some of these phages utilize polar pili for adsorption, whereas others either are not known to be pilus dependent or have been shown to attach nonselectively to the bacterial wall and hence have been listed as cell wall phages Table 5 ; 7, 42, D. E. Bradley and T. L. Pitt, J. Gen. Virol., in press ; . Each phage was propagated on PU21 and then titered on PU21, PU21 pMG1 ; , or PU21 pMG2 ; to determine the efficiency of plating. Plasmidcontaining strains had only a slight reduction in the efficiency of plating pilus phages C5, F116, P04, PP7, and 7S, but did not propagate pilus phage M6 or cell wall phages B3, D3, E79, G101, or PB1 Table 5 ; . Actually, with undiluted lysates of phage B3 minute plaques were observed, and with undiluted phage D3 there was partial lysis, but propagation did not occur in either case and host-modified phage could not be detected. Interference with propagation occurred at a stage subsequent to phage adsorption since adsorption of B3, D3, E79, G101, PB1, and M6 by PU21 and PU21 pMG2 ; was equivalent Table 6 ; . Effect of pMGl and pMG2 on pyocin type. Another commonly used technique for characterizing P. aeruginosa isolates is pyocin typing. PU21, like most P. aeruginosa 26 ; , is pyocinogenic, and by the cross-streaking plate technique of Gillies and Govan 22 ; it inhibited seven of eight primary indicator strains and four of five in an additional subset Table 7 ; . Remarkably, PU21 pMG1 ; and PU21 pMG2 ; had no pyocin activity against these indicators and thus became pyocin nontypable. Farmer and Herman have developed another procedure for pyocin typing that utilizes mitomycin C in broth culture to induce pyocin formation. Lysates are then spot tested against 27 indicator strains 19 ; . By this technique, PU21 had pyocin activity for 20 of 27 indicators Table 8 ; . Again the R plasmids interfered with.

The activities of the AWRI, research, development and knowledge transfer, will be conducted for the benefit of all Albertans and implemented within the values enunciated for all Alberta Ingenuity initiatives: Excellence The AWRI will pursue only excellent research and innovation and support only the best people identified through a rigorous peer review process. This process will ensure the highest standards of quality are met as determined by stringent peer reviews and by an internationally-recognized scientific advisory board. Alberta Ingenuity's International Science and Engineering Advisory Committee members will be involved, as appropriate, to ensure a robust international standard of excellence. Pan-Alberta The AWRI will bring together stakeholders from public and private organizations across the province that have the capacity for research and innovation. These stakeholders may include Alberta industry leaders, companies, Alberta's three major research Universities, Alberta colleges and technical institutes, government research organizations, other research institutes, and associations. Collaborative The AWRI will enable and nurture mutually supportive collaborations between and among science and engineering researchers and innovators, water managers and decision makers, industry research and innovation leaders with a focus on the pan-Alberta scope of the initiative. Success will be built on establishing and sustaining provincial, national, and international research collaborations and developing effective industry partnerships. Another study, it was also shown that mitomycin C is mainly activated by cytochrome P450 reductase to DNA binding adducts in COS1 cells expressing human cytochrome P450 reductase. Only at high concentrations of mitomycin C did DT-diaphorase play a role in the activation Joseph et al., 1996 ; . Another clinically used prodrug, tirapazamine, is a bioreductive agent that is activated by a one-electron reduction by cytochrome P450 reductase to a cytotoxic nitroxide radical intermediate before further reduction to the nontoxic metabolite SR 4317 3-amino-1, 2, ; Walton et al., 1989; Brown, 1993; Denny and Wilson, 2000 ; Table 5 ; .

The chemotherapy and its hydrophilic properties. Extensive peritonectomy causes a small increase in drug clearance. The area under the curve ratio of intraperitoneal to intravenous drug is dependent on the rate of diffusion across the peritoneal-plasma barrier and the rate of drug metabolism or excretion from the plasma. 1.11.2 The possibility of intraperitoneal chemotherapy administration as an alternative to its systemic delivery in patients with resectable gastric cancer was raised over a decade ago. 93 ; In six randomized studies, in patients with gastric cancer it was associated with a decreased incidence of peritoneal spread and a tendency for improved survival. 94 ; In another phase III randomized trial, patients with stage III gastric cancer, T3-4 tumors serosal invasion ; and N1 lymph nodes regional resectable ; had a marked survival advantage compared to those treated with surgery alone. 95 ; 1.11.3 As with every method of regional chemotherapy, the pharmacokinetic advantage of intraperitoneal chemotherapy is limited to the abdominal and pelvic surfaces. 96 ; Also, intraperitoneal chemotherapy acts mainly by direct diffusion of drug and high concentration tissue penetration is limited to 1-2 mm from the surface. 97-99 ; That is why perioperative intraperitoneal distribution of a drug carrying solution before adhesions are formed is crucial for its therapeutic effect. 91-93 ; Studies in patients with pseudomyxoma peritonei treated by cytoreductive surgery and intraperitoneal chemotherapy demonstrated that cancer tends to recur on unexposed surfaces not treated due to a compromised distribution of intraperitoneally administered drug. 100 ; 1.12 Pharmacokinetics and pharmacodynamics of intraoperative intraperitoneal chemotherapy Duration of exposure of cancer cells to the regional chemotherapy are important for the effectiveness of intraperitoneal chemotherapy. At the same time, intraoperative administration prolongs operative time. It is obvious that duration of intraperitoneal chemotherapy should be limited to the shortest reasonable period of time. In vitro studies of human gastrointestinal cancer cells exposed to chemotherapeutic drugs for 1 hour have demonstrated that concentrations of 10 mcg ml of mitomycin C and cisplatin produced cytotoxic effect in 70-80% of cancer cells. 101 ; Pharmacokinetic studies of intraoperative intraperitoneal chemotherapy demonstrated that 75% to 90% mitomycin C and cisplatin was absorbed during the first hour. 102, 103 ; Consequently, duration of intraoperative intraperitoneal chemotherapy should be approximately one hour. 1.13 Hyperthermic potentiation of chemotherapy effect There are several ways of potentiating cytotoxic effects of chemotherapy and among them is hyperthermia. It can help overcome drug resistance by increasing tissue penetration, inhibiting cell repair mechanisms and by temperature.

Mitomycin bioreductive enzymes known to be present in these cells, i.e. NADPH cytochrome c P450 ; reductase, DT diaphorase, and NADHcytochrome b5 reductase. To ascertain the degree of resistance of MCRA-expressing cell lines to MC and POR, a clonogenic assay was performed under both aerobic and hypoxic conditions Fig. 3 ; . Profound resistance to the mitomycins was observed under aerobic conditions in the MCRA-expressing cell lines, compared with parental cells, at drug concentrations as high as 500 M Fig. 3 A and C ; . Cell survival was not affected by drug exposure times of up to hours after treatment with 80 M MC data not shown ; . In contrast, parental CHO cells were extremely sensitive to the mitomycins at these high drug concentrations under aerobic conditions, with surviving fractions that were several orders of magnitude less than those observed in MCRA-expressing cells Fig. 3 A and C ; . Most human and animal tumor-cell lines display an even greater sensitivity to these agents than the relatively resistant CHO cells 2123 ; . Under hypoxic conditions, the MCRA-expressing cells were almost as sensitive to the mitomycins as the parental cell and mrv.

Teachers might also consider these alternatives; 1 Minimise the complexity of verbal communications, rephrase and repeat information if students do not understand. Use plain language and convert texts to plain language. This assists students who have an intellectual disability, some forms of learning disability and students with a hearing impairment. 2 Computers offer flexibility and are of particular support to students with vision impairments and blindness. Students can print out a large print copy, read it on a screen using screen enlargement software, listen to it on voice synthesiser or convert it into Braille. 5 Many students use Braille. The Perkins Braillers are available across all countries. Braille can be produced 5 Lessons can be readily taped using a cassette recorder. Students who experience writing difficulties can also provide information on audiotape. Taped versions of books are sometimes available in libraries. 6 Enlarging text and images is simply done by photocopier or enlarging computer software. Teachers can also write text with bigger letters on a sheet. Some students might use a hand or sheet magnifier or closed circuit television. 7 For students who are deaf or hard of hearing, the use of videos with captions facilitates access to the material. 8 A `note-taker' could also support students; the note-taker can be a student who is studying the same class or a person from outside the class who has the appropriate skills and background to record information. directly a Braille embosser. Today, Braille texts can be produced from computer text-file format and printed out using a Braille printer. However, in many countries, Braille text is also produced on thick paper in contexts where resources are not sufficient for purchasing Braille paper. 4 Tactile images can be drawn on Braille paper using a special mat and stylus which produce a relief image that can be felt. Equally, they can be produced by using locally available materials, such as string, sand, sticks, seeds, etc and muse and mitomycin.

2. It leads to new observations of text phenomena, including some related to nuclei, such as the most-favorable-reader hypothesis. 3. The advantages of a recursive theory are obtained for text structure. Beyond the phenomena identified above, RST appears to be useful in accounting for other kinds of discourse phenomena. We have found no boundary for its uses; it is like trying to delimit the uses of a grammar. We have identified the following as particularly attractive applications: Thematization and text development . Distributions of tense selections in text Lexical selection Patterned shifts of hypotheticality, identifiability, or conditionality - Patterns of use of conjunctions - Purposeful clause combining . Distribution of topicalization markers - Text ordering under way ; - Relating coherence to cohesive devices.

Strain surveillance is important for the detection and monitoring of escape variants, for the monitoring of population immunity, and serves as an early warning system. There is no sentinel system in place for the systemic collection of B. [para]pertussis strains. Clinical isolates are sent to the RIVM for confirmation or classification on an ad hoc basis. At the RIVM, strains are serotyped en genotyped. Serotyping characterizes the fimbrial [sero]types produced by the bacteria. This is relevant since fimbriae are important protective antigens and are used in a number of acellular pertussis vaccines.4244 Furthermore, there is evidence that Fim2 strains are more virulent than Fim3 strains.45 Finally, changes in frequencies of fimbrial serotypes are associated with changes in population immunity and may serve as an early warning system.46 Genotyping is used to detect shifts in the B. [para]pertussis population, which may reflect changes in population immunity. In addition, genotyping is used to characterize the genes for proteins, which are part of pertussis vaccines. This allows the detection and monitoring of escape variants.47 Strain surveillance has revealed major shifts in the Netherlands B. pertussis population.47-50 In general vaccine-type surface proteins have been replaced by novel types. Strains used for the production of acellular vaccines originate from the 1940s to 1950s and consequently there is a mismatch between acellular vaccines and circulating strains. Several studies have indicated that strain variation affects vaccine efficacy in the mouse model.51-53 The mismatches between vaccine strains and circulating strains are relatively minor, and may be less relevant in recently immunized individuals. However, strain variation may be important in individuals with waning immunity. In fact, there is a very direct temporal relationship between the most recent shift in the B. pertussis population and the current pertussis epidemic.50 In summary, strain surveillance has provided evidence that the emergence of escape variants has played an important role in the pertussis epidemics in the Netherlands.54, 55.

Bladder cancer is an important cause of morbidity and mortality, and, in contrast to the United States, its incidence and mortality rates are still increasing in European countries, even though the majority of new cases are diagnosed as early and superficial tumors 1, 2 ; . Transitional cell carcinomas of the bladder can be classified into two groups with distinct behavior and different molecular profiles: a ; low-grade tumors, which include papillary and usually superficial lesions; and b ; high-grade tumors, which comprise papillary and nonpapillary, often invasive lesions. Superficial cancers Ta-T1 stages ; account for 70 80% of newly diagnosed bladder cancers. First-line treatment is transurethral resection, fulguration, or laser coagulation, but approximately two-thirds of patients develop recurrences, with a progression of grade and stage despite the macroscopically complete eradication of the primary lesion 35 ; . The high rate of recurrence and stage progression represents an important challenge for the correct management of these patients. Intravesical therapy is usually given, but, up to now, no treatment has resulted in a significant improvement in overall survival. Intravesical immunotherapy with Bacillus Calmette-Guerin BCG ; is currently the most effective approach for the therapy and prophylaxis of superficial bladder cancer 3, 57 ; , but it is associated with serious morbidity 5, 8, 9 ; . Moreover, only two-thirds of patients respond to BCG treatment, and, among these, one-third are destined to relapse 1, 4 ; . An improvement in overall survival has also never been demonstrated 5 ; . Up now, antiblastic agents such as thiotepa, doxorubicin, epidoxorubicin EPI ; , and mitomycin C used intravesically in clinical trials on large case series have not proven capable of significantly reducing disease progression or improving overall survival 6, 10, 11 ; . Valrubicin, which was used recently as a second-line intravesical chemotherapy in BCG-refractory patients, produced complete responses in only 20% of cases 12, 13 ; . Therefore, cystectomy represents the treatment of choice for these patients. A great deal of interest has been focused on research into new drugs or new drug combinations for intravesical chemotherapy. Gemcitabine GEM ; has proven to be effective when systemically administered to advanced bladder cancer patients 14 16 ; and is also active, with minimal bladder irritation, in instillation treatment 4, 17 ; . EPI has been shown to be active as a single agent in intravesical therapy 18 20 ; . the present study, we investigated the cytotoxic activity of GEM and EPI and their interaction in two human bladder cancer cell lines by reproducing local infusion or systemic. MATERIALS AND METHODS Bacterial strains, plasmids, colicin A, and bacteriophage. The bacterial strains used in this study are listed in Table 1. To construct the cpxA + plasmid pOK101, a 1.5-kilobase cpxA + , BamHI-EcoRI restriction fragment was cloned into the pINIII Ipp5 lacPO ; A3 laclIq expression vector 17 ; digested with BamHI and EcoRI. The cpxA + fragment consisted of the 1, 508-base-pair DraI-StuI fragment previously described 37 ; , along with surrounding polylinker DNA from the pUC19 cloning vector. The cloned fragment consists almost entirely 1, 374 base pairs; 37 ; of the cpxA coding sequence. Expression of cpxA in pOK101 is nominally from the lpp and lac promoters of the vector. Immunooverlay Western ; blot analysis showed higher CpxA levels when transformants were induced, but CpxA protein accumulation over background could be detected even in the absence of an inducer R.

Available from: : library.downstate EBM2 contents .1. Persistence of Mycobacterium tuberculosis infection despite prolonged chemotherapy is a major problem in tuberculosis control 3 ; . Hypoxic dormant bacilli are, in contrast to oxic replicating organisms, not effectively killed by conventional antimycobacterials and could be one of the factors contributing to the persistence 1 ; . Metronidazole 7 ; , nitrofurantoin 4 ; , and PA-824 a nitroimidazopyran ; 5 ; are the first leads that show activity against dormant bacteria. The compounds appear to act as prodrugs that require reduction of their nitro group to reactive intermediates that then cause damage and death of the bacilli. The finding that prodrugs that require reduction to unfold their antimicrobial activity are effective against hypoxic dormant bacilli prompted us to question whether mitomycin C might possess antidormancy activity. This drug is used in the chemotherapy of hypoxic solid tumours and requires reduction to become biologically active 6 ; . Here, we report the analysis of the antimicrobial activity of mitomycin C on growing and dormant Mycobacterium bovis BCG Pasteur ATCC 35734. Mitomycin C showed an MIC 4 ; of 5 1.7 ng ml ; . agreement with our previous report, a 104-fold-higher MIC 50 M ; of nitrofurantoin was observed and metronidazole did not show inhibition of growth MIC of metronidazole 1, 000 M ; 4 ; . Figure 1A shows that mitomycin C at MIC appears to be bacteriostatic. Incubation of growing cultures with 10 times the MIC of mitomycin C 50 nM ; resulted in a 104-fold decrease in viability after 5 days. To grow dormant organisms, we employed the Wayne dormancy culture system. Wayne's model is based on growth of the bacilli in sealed tubes with stirring. Initially the cultures grow exponentially and consume oxygen. A temporal oxygen gradient is generated, and when oxygen is depleted the cultures enter stationary phase. The hypoxic stationary-phase bacteria do not replicate but maintain viability; they are in a state of dormancy 2, 8 ; . Figure 1B shows that exposure of dormant bacilli to 500 nM mitomycin C resulted in a 30-fold reduction in viable counts after 5 days. To achieve a kill that was similar to that observed for mitomycin C, a 1, 000fold higher concentration of nitrofurantoin was required: 500 M nitrofurantoin reduced viability of the dormant culture 90-fold after exposure for 5 days, while 500 M metronidazole reduced viability of the oxygen-starved culture only 2-fold after exposure for 5 days 4 ; . Comparison of the activities of mitomycin C against growing Fig. 1A ; and dormant Fig. 1B ; cultures shows that the growing bacilli were more sensitive to the drug. Furthermore, it is interesting to note the difference in the exposure time-kill curves for growing and dormant cultures. Growing cultures were killed as expected ; in an exposure time-dependent fashion. In contrast hypoxic cultures appear to lose viability rapidly 10-fold, and then the CFU level off. Whether this indicates the presence of a mitomycin Cresistant subpopulation in the dormant culture remains to be elucidated. In conclusion, the comparison of the effects of mitomycin C and the nitroheterocyclic drugs on dormant bacilli revealed that mitomycin C showed activity at a 1, 000-fold-lower concentration. Furthermore, mitomycin C showed a drastically lower MIC.
And Cesium -137 are the main sources of gamma rays used in mutation breeding. They are stored in lead containers when not in use and operated by remote control mechanisms to irradiate plant material. 3.1.2 UV RAYS Ultraviolet light has limited penetrating ability, therefore its use is limited to treating spores, pollen grains cells and cultured tissue. Wavelengths in the range of 2, 500 to 2, 800 nm are biologically most effective because this is the region of maximal light absorption by nucleic acids. 3.1.3 BETA PARTICLES Beta particles such as those from Phosphorus-32 and Sulfur- 35 produce effects in tissues similar to those of X- or gamma rays. The penetrating ability of beta particles is lower than that of X- and gamma rays. The lower penetrating ability of beta particles can be overcome by putting the radioisotope in a solution and administering them to the plant material. P-32 and S-35 may then be incorporated directly into cell nucleus giving a somewhat greater localization of the site of action. But, because of the variability from tissue to tissue and cell to cell, it is difficult to determine the exact dose given by an internal emitter in plant material. 3.1.4 NEUTRONS Neutrons have been shown to be highly effective for the induction of mutation in plants but, a certain degree of confusion exists concerning the results of early experiments and due to lack of adequate dosimetric techniques. 3.1.5 ION BEAMS Ion beams can give a large amount of energy with high LET Linear Energy Transfer ; to the localized position in tissues. Therefore, we can expect different biological effects will be given to plant materials compared with low LET radiations, such as, gamma- and x-rays. Also ion beams can produce large structural changes in chromosomes and DNA. So we can expect to induce different kinds of mutations in plants with high frequency than gamma- and x- rays. But further basic and practical researches should be made to use ion beams efficiently in the future. 3-2 CHEMICAL MUTAGENS The number of chemical mutagens is numerous and continuously increasing. But for mutation inductin in cultivated plants only a few are readily very useful and most of them belong to the special calss of alkylating agents such as, ethyl methane sulhonate EMS ; , diethyl sulfate dES ; , ethyleimine EI ; , ethyl nitroso urethane ENU ; , ethyl nitroso urea ENH ; , and methyl nitroso urea MNH ; . A number of workers also found azides as effective mutagens. 3.2.1 BASE ANALOGUES AND RELATED COMPOUNDS True base analogues are closely related to DNA bases, adenine, guanine, cytosine or thymidine and can be incorporated into DNA without affecting its replication. But analogue differs from the normal base in certain substitutes hence its electronic structure is modified and it can be expected that occasional pairing errors will occur at the time of DNA replication after the analogue has been incorporated. The most frequently used analogues are 5-bromo-uracil BU ; and 5-bromo-deoxyuridine BUDR ; , which are analogues of thymine. Apart from true analogues, it has been found that N-methylated oxypurines have a chromosome effect. The most efficient compounds are 8-ethoxy caffeine EOC ; and 1, 3, 7, tetramethyluric acid TMU ; , but their mode of action is still unknown. Maleic hydrazide MH ; , an isomer of uracil, induces chromosome breaks in cell and aberrations are localized in heterochromatic regions near the centromere of the chromosomes. 3.2.2 ANTIBIOTICS Antibiotics such as azaserine, mitomycin C, streptonigrin and actinomycin D have been found to have chromosome breaking properties, but their usefulness are limited. 3.2.3 ALKYLATING AGENTS This is the most important group of mutagenic chemicals for mutation induction in cultivated plants. They have one or more reactive alkyl groups which can be transferred to other molecules. They react 13.
DPN receive equal exposure. Pincus et al.17 found that patients on both MTX and low-dose prednisolone had better long-term drug continuation than those on MTX alone; there was no effect on the discontinuation rates of the other DMARDs studied. Utley et al. have recently questioned the validity of Kaplan-Meier plots when applied to drug studies in rheumatology.21 They argue that the underlying assumptions upon which Kaplan-Meier analysis depend may not hold, particularly when recruitment into a study takes place over an extended time period. For example, we cannot assume that a hypothetical ; patient recruited in 1989 and started on MTX experiences the same ADR hazard as a patient recruited in 1999. Similarly, two patients recruited in 1989 and started on MTX, one immediately and one 5 years later after unsuccessful treatment with two other DMARDs, may not experience the same hazard of discontinuation from ADRs or inefficacy. Intuitively, it seems unlikely that these assumptions will hold. At the very least, improvements in our practice over the last 13 years ensure that patients we see in our clinics today start DMARDs earlier in their disease, receive folic acid with their MTX22 and are provided with appropriate information, reassurance and ready access to a telephone helpline. The distinction between a statistically different survival curve and a meaningful clinical difference is a key point. Whether the underlying reasons are purely pharmacological or not, courses of MTX given in our clinical cohort were clearly continued for longer than other DMARDs. The slight differences seen between SAS, myocrisin and DPN are less likely to be of clinical relevance despite their `statistical significance'. We have tried to present incidence and time-course data unadorned, and point out only the clear clinical differences in our experience of monitoring these drugs.
