Mutation creates new alleles. Each new allele enters the gene pool as a single copy amongst many. Most are lost from the gene pool, the organism carrying them fails to reproduce, or reproduces but does not pass on that particular allele. A mutant's fate is shared with the genetic background it appears in. A new allele will initially be linked to other loci in its genetic background, even loci on other chromosomes. If the allele increases in frequency in the population, initially it will be paired with other alleles at that locus -- the new allele will primarily be carried in individuals heterozygous for that locus. The chance of it being paired with itself is low until it reaches intermediate frequency. If the allele is recessive, its effect won't be seen in any individual until a homozygote is formed. The eventual fate of the allele depends on whether it is neutral, deleterious or beneficial. Neutral alleles Most neutral alleles are lost soon after they appear. The average time in generations ; until loss of a neutral allele is 2 Ne where N is the effective population size the number of individuals contributing to the next generation's gene pool ; and N is the total population size. Only a small percentage of alleles fix. Fixation is the process of an allele increasing to a frequency at or near one. The probability of a neutral allele fixing in a population is equal to its frequency. For a new mutant in a diploid population, this frequency is 1 2N. If mutations are neutral with respect to fitness, the rate of substitution k ; is equal to the rate of mutation v ; . This does not mean every new mutant eventually reaches fixation. Alleles are added to the gene pool by mutation at the same rate they are lost to drift. For neutral alleles that do fix, it takes an average of 4N generations to do so. However, at equilibrium there are multiple alleles segregating in the population. In small populations, few mutations appear each generation. The ones that fix do so quickly relative to large populations. In large populations, more mutants appear over the generations. But, the ones that fix take much longer to do so. Thus, the rate of neutral evolution in substitutions per generation ; is independent of population size. The rate of mutation determines the level of heterozygosity at a locus according to the neutral theory. Heterozygosity is simply the proportion of the population that is heterozygous. Equilibrium heterozygosity is given as H 4Nv [4Nv + 1] for diploid populations ; . H can vary from a very small number to almost one. In small populations, H is small because the equation is approximately a very small number divided by one ; . In biologically unrealistically ; large populations, heterozygosity approaches one because the equation is approximately a large number divided by itself ; . Directly testing this model is difficult because N and v can only be estimated for most natural populations. But, heterozygosities are believed to be too low to be described by a strictly neutral model. Solutions offered by neutralists for this discrepancy include hypothesizing that natural populations may not be at equilibrium. At equilibrium there should be a few alleles at intermediate frequency and many at very low frequencies. This is the Ewens- Watterson distribution. New alleles enter a population every generation, most remain at low frequency until they are lost. A few drift to intermediate frequencies, a very few drift all the way to fixation. In Drosophila pseudoobscura, the protein Xanthine dehydrogenase Xdh ; has many variants. In a single population, Keith, et. al., found that 59 of 96 proteins were of one type, two others were represented ten and nine times and nine other types were present singly or in low numbers.
Ethicillin-resistant Staphylococcus aureus MRSA ; is usually considered a hospital-acquired HA ; organism. As highlighted elsewhere in this issue of CMAJ , infections with communityacquired CA ; strains of MRSA are being noted more frequently. The molecular and antimicrobial resistance profiles of these CA-MRSA strains are distinct from HA-MRSA strains. Practitioners must be prepared to diagnose, treat and help prevent these infections. This brief review addresses issues relevant to the identification, prevention and management of CA-MRSA infections for Canadian practitioners. MRSA comprises the S. aureus strains that are resistant to all -lactam antimicrobials, including penicillins, cephalosporins and monobactams. A part of the normal flora of humans, S. aureus colonizes the anterior nares. It is also an important human pathogen that causes a broad spectrum of infections, from trivial to life-threatening. CA-MRSA is not new to Canada; it has been endemic in northern aboriginal communities on the prairies for almost 20 years. But the national epidemiology is changing, mirroring that reported in the United States. 1 Although CA-MRSA infections in Canada have previously been uncommon in nonaboriginal communities, these.

K. Jakovci, Z. Krecak, M. Krcmar and A. Ljubici Ruer Boskovi Institute, Zagreb, Croatia The standard axion, a hypothetical light pseudoscalar spinless non-charged boson, is postulated to explain why CP violation in the strong interactions have not been found. In general, it interacts with leptons, photons and hadrons. Due to the similarity and generic interaction with pions, its mass is given by formula mafa mf , f denoting decay constants. Its existence has not been confirmed by experiments and thus DFSZ GUT and KSVZ models of invisible axions were invented. KSVZ axion coupling to leptons is suppressed. Astrophysical and cosmological considerations predict axion mass window 10-5eV ma 10-2eV ; relating to cold dark matter. The hadronic axion is sort of KSVZ axion type which does not couple to photon. Its mass window 10 eV ma relates to hot dark matter. Based on the axial nature of axions and magnetic nuclear transitions, we here present a scenario for a hadronic axion search. At one particle de-excitation of nucleus via magnetic transition, emission of photon, conversion electron or hadronic axion occurs. If resonant conditions are fulfilled, that axion may excite another distant nucleus of the same type and it is possible to record such axion event by detection of accompanying photon and or conversion electron. The first search for solar hadronic axions emitted from Fe-57 nucleus has been proposed by Moriyama [1]. We have performed two experiments aimed at search for solar hadronic axions emitted from 1st excited levels - 14.413 keV of Fe-57 nucleus [2] and 477.672 keV of Li-7 nucleus [3] which decay via M1 transitions. No evidence of hadronic axions existence has been found in these experiments. Therefore, upper limits of hadronic axion mass were found to be 745 eV and 32 keV, respectively. In this experiment we searched for solar hadronic axions using the M1 decay of 1st excited 9.4051 keV level of Kr-83 nucleus. Resonant axion capture is expected to occur in laboratory inside a proportional gas counter filled with high purity krypton at room temperature and pressure of 2 bar. The counter is tuned to detect photons with energies from 5 to 25 keV applying anode bias voltage of + 1600 V. It is calibrated using Fe-55 and Cd-109 X-ray emitters. Our preliminary experimental result gives an upper limit of axion mass of about 5 keV.

Every time I didn't feel quite with it I would blame it onto Meniere's, so when I had the Meniere's operation I expected it to be better, and I got worse. The symptoms got worse: pressure in my head, pressure across here, pains in my head. My eyes were funny, I got very anxious, I thought I had real problems -hence the scan, and all the other things that I had. Another widely used form of surgery consists of a range of procedures intended to prevent attacks of vertigo in patients with Mnire's disease, essentially by relieving the increased pressure in the fluid endolymph ; in the vestibular organ which characterises this condition. This type of surgery does not entail destruction of hearing and vestibular function -- an important consideration, since about one-third of those with Mnire's disease eventually find both ears are affected. A variety of techniques are employed most commonly, the "endolymphatic shunt" ; , all of which have been reported as achieving a roughly similar success rate, averaging about 70%, with fewer and less serious complications than the more destructive procedures e.g. Paparella, 1991; Raivio et al., 1989; Smith & Pillsbury, 1988 ; . In some cases, repeat operations are needed after a few years, and success rates in halting the deterioration in hearing occurring in Mnire's disease which can be objectively measured ; are significantly lower than those reported for control of vertigo. In practice, reported rates of improvement in symptoms following shunt operations vary quite widely, ranging from 49% to 90%, with the better rates tending to be reported, naturally, by the surgeons who are most enthusiastic about the technique. Unfortunately, almost all of the published clinical trials have suffered from crucial methodological weaknesses, the most serious being the lack of independent, blind assessment of improvement, and or absence of a suitable control group. The latter failing has resulted partly from an understandable reluctance to withhold treatment, and partly from the assumption on the part of many clinicians that an adequate within-subject control condition is provided by the long base-line period of disabling vertigo, unalleviated by drug therapy, which generally constitutes the criterion for offering surgery. However, the course of Mnire's disease is extremely unpredictable, consisting of fluctuating clusters of attacks, which often become progressively more frequent and severe over a few years, and then tend to become milder and less frequent, eventually ceasing Haye & Quist-Hanssen, 1976; Stahle et al., 1989 ; . Consequently, a certain rate of improvement may be expected on the basis of statistical probability alone. Moreover, the "placebo" effects associated with surgery are generally ignored, even though they may constitute important aspects of the treatment. Features of undergoing surgery which might affect the experience of illness include: the recognition and sanctioning of the individual's status as truly and seriously disabled, and the consequent removal of the stigma associated with suspected hypochondria; a hitherto unparalleled level of attention, interested sympathy and explanation; communication of the belief that the ultimate form of treatment has been provided; and possibly advice or therapy to assist compensation following the operation see, for example, the recommendations for pre-surgical counselling of the patient given by BaggerSjbck, 1988 ; . Indeed, in the only double-blind, placebo-controlled study of endolymphatic shunt surgery, the same success rate -- about 70% -- was observed in both the active and the placebo groups, and no significant between.

AZULFIDINE Tablets are indicated: a ; in the treatment of mild to moderate ulcerative colitis, and as adjunctive therapy in severe ulcerative colitis; and b ; for the prolongation of the remission period between acute attacks of ulcerative colitis. CONTRAINDICATIONS AZULFIDINE Tablets are contraindicated in: Patients with intestinal or urinary obstruction, Patients with porphyria, Patients hypersensitive to sulfasalazine, its metabolites, sulfonamides, or salicylates. WARNINGS Only after critical appraisal should AZULFIDINE Tablets be given to patients with hepatic or renal damage or blood dyscrasias. Deaths associated with the administration of sulfasalazine have been reported from hypersensitivity reactions, agranulocytosis, aplastic anemia, other blood dyscrasias, renal and liver damage, irreversible neuromuscular and central nervous system changes, and fibrosing alveolitis. The presence of clinical signs such as sore throat, fever, pallor, purpura, or jaundice may be indications of serious blood disorders. Complete blood counts, as well as urinalysis with careful microscopic examination, should be done frequently in patients receiving AZULFIDINE see PRECAUTIONS, Laboratory Tests ; . Oligospermia and infertility have been observed in men treated with sulfasalazine; however, withdrawal of the drug appears to reverse these effects. PRECAUTIONS General: AZULFIDINE Tablets should be given with caution to patients with severe allergy or bronchial asthma. Adequate fluid intake must be maintained in order to prevent crystalluria and stone formation. Patients with glucose-6 phosphate dehydrogenase deficiency should be observed closely for signs of hemolytic anemia. This reaction is frequently dose related. If toxic or hypersensitivity reactions occur, the drug should be discontinued immediately. Information for Patients: Patients should be informed of the possibility of adverse reactions and of the need for careful medical supervision. The occurrence of sore throat, fever, pallor, purpura, or jaundice may indicate a serious blood disorder. Should any of these occur, the patient should seek medical advice. They should also be made aware that ulcerative colitis rarely remits completely, and that the risk of relapse can be substantially reduced by continued administration of AZULFIDINE at a maintenance dosage. Patients should be instructed to take AZULFIDINE in evenly divided doses preferably after meals. Additionally, patients should be advised that sulfasalazine may produce an orange-yellow discoloration of the urine or skin. Laboratory Tests: Complete blood counts, including differential white cell count and liver function tests, should be performed before starting AZULFIDINE and every second and vibramycin.
Treatment of isolated hepatocytes with the tumorpromoting agent, 4-phorbol 12b-myristate 13a-acetate PMA ; produced a time- and dose-dependent, noncompetitive inhibition of ax-adrenergic responses, including the activation of phosphorylase, increase in Ca2 * efflux, increase in free cytosolic Ca2 + , and release of myo-inositol- 1, 4, 5-P3. The actions of [%arginine] vasopressin AVP ; on liver cells were also inhibited by PMA, but the inhibition could be overcome by high AVP concentrations. No significant inhibition of 4adrenergic andglucagon-mediated activation of phosphorylase was induced by PMA and no inhibitory or synergistic effectsof PMA were observed on the dosedependent activation of phosphorylase by the Ca2 + ionophore A23187. In radioligand bindingstudies, PMA did not directly interfere with ['Hlprazosin specific binding, the displacement of [3H]prazosin by - ; -norepinephrine nor with ['HIAVP specific binding to purified liverplasma membranes. Plasma membranes prepared from livers perfused with PMA exhibited a 30-44% reduction in ['Hlprazosin binding capacity. Under identical conditions ['HIAVP binding was unchanged. The al-receptors remaining in membranes from PIMA-treated livers had equivalent affinities ['Hlprazosin and - ; -norfor epinephrine, and were unaffected in termsof coupling to guanine nucleotide-regulating proteins indicated as by the abilityof guanosine 5'- , y-imido ; triphosphate to promote the conversion of the remaining cul-receptors intoa low affinity state. These data indicate that tumor promotersare potent antagonists of al-adrenergicand vasopressin low dose ; responses in liver. It is proposed that PMA acting via protein kinase C which presumably mediates the action of PMA ; exerts its inhibitory action on w-adrenergic responses at the al-adrenergic receptor itself and also at a site close to or before myo-inositol-1, 4, 6Ps release.

Production of type 1 pro-inflammatory cytokines, such as TNF- , IFN- , and IL-12 Ross et al., 1997; Hasko et al., 1998b; Liang et al., 1998 ; . These effects, however, are independent from the simultaneous increase of IL-10 production Ross et al., 1997; Hasko et al., 1998b ; . Moreover, the suppressive effects of this drug on type 1 cytokines, in parallel with the increase of IL-10 have been recently linked to rolipram-induced prevention and amelioration of the course of experimental collagen-induced arthritis and EAE in rodents and nonhuman primates, and diabetes in NOD mice Genain et al., 1995; Ross et al., 1997; Liang et al., 1998 ; . Recent evidence indicates that all these experimental models of autoimmune diseases are driven by overproduction of type 1 cytokines, particularly IL-12 and TNF- Segal et al., 1998 ; . XV. Conclusions The presence of sympathetic noradrenergic nerve fibers in lymphoid organs, the release of NE from the sympathetic nerve terminals in these organs, and the expression of adrenoreceptors on lymphoid cells, which are able to respond functionally to stimulation, suggests that NE may meet the criteria for neurotransmitter neuromodulator in lymphoid organs. The varicose axon terminals of the sympathetic nerve do not make synaptic contact with immune cells. Similar to many organs in the periphery, the release of NE is subject to presynaptic modulation via 2A C-ARs. NE released from sympathic axon terminals diffuses far away from the release site; therefore NE transmits its signals nonsynaptically. Thus, the SNS may provide major integrative and regulatory pathway between the CNS and the immune system. Sympathetic-immune interactions are undoubtedly complex. A few recent studies suggest that endogenous CAs modulate the function of primary lymphoid organs, such as the bone marrow and the thymus. However, the role of sympathetic innervation and endogenous CAs in regulation of hematopoiesis and thymocyte development remains poorly understood. In addition, there is almost complete lack of knowledge about how CAs might affect mucosal immunity. Evidence accumulated in the last decades indicates that, peripherally, both NE released from the nonsynaptic sympathetic nerve terminals in lymphoid organs and blood vessels and epinephrine released from the adrenal medulla are involved in fine tuning of immune responses. Very similarly, steroid synthesis and secretion in the adrenal cortex is also under direct local tuning by NE and or DA released from nonsynaptic noradrenergic varicosities in the zona glomerulosa. Morphological and neurochemical evidence indicates that a substantial proportion of the noradrenergic nerve endings lie in close proximity to zona glomerulosa cells without making synaptic contact, thus providing evi and tramadol.
SULFASALAZINE Sulfasalazine Azulfidne ; is a salicylate that is altered by an addition to the benzene ring of salicyclic acid. It is poorly absorbed 10-15% absorbed unchanged ; and is converted by intestinal microflora to sulfapyridine and mesalamine. It has a labeled use for ulcerative colitis and mild regional enteritis. Frequent unlabeled uses include Crohn's disease and scleroderma. Dermatologists have occasionally used in for its antiinflammatory properties to treat psoriasis and pyoderma gangrenosum.

It has also been anecdotally reported to successfully treat pressure urticaria. I have had anecdotal success using this regimen in two patients. I have had one failure in a patient with severe solar urticaria.

Of 40 pyridoxal phosphate indicates that 80% of the original activity of the apoenzyme was recoverable upon addition of the cofactor. In contrast to its lack of activity in Reaction 1, the apoenzyme retained most of its capacity to assist the A protein in cleaving indolylglycerol phosphate to indole and 3-phosphoglyceraldehyde. Addition of 80 pyridoxal phosphate to the reaction mixture, however, did result in a significant increase in the activity of the protein pair in this reaction Table III ; . Creighton and Yanofskyl have observed that pyridoxal phosphate increases the affinity of the A and B components for each other in solutions containing Tris buffer. The presence of even more A protein than was used in the experiment of Table III did Saturanot increase the activity of the apoenzyme, however. tion experiments with various amounts of B protein and a constant amount of A protein showed that more apoenzyme B than normal B protein was needed to evoke maximal activity from a 1 T.

Eugne Devic was born in 1850 in La Cavalerie, a small village in Aveyron, in southern France. He trained at the medical college of Lyon and later worked on a variety of subjects, and was especially interested in typhoid fever and cardiovascular diseases. In the field of neurology, he wrote about infantile chorea, "polyneuritic psychosis", mental disorders in typhoid fever, cerebral glioma, corpus callosum tumours, meningeal angiosarcoma, and post-hemiplegic contracture. In December 1892 he saw a 45 year old French woman for intractable headache and depression with "general weakness" at the Htel-Dieu Hospital of Lyon. On 27 January urinary retention appeared, followed by complete paraplegia and bilateral blindness. She died from bedsores on 4 March 1893. The case and pathological examination, which confirmed lesions in the spinal cord and optic nerves, was presented as a clinicopathological study at the First Congress of Internal Medicine in Lyon in 1894. Here Devic mentioned 16 other similar cases reported in Europe and the USA. These 17 cases were studied in detail in the doctoral thesis of Fernand Gault --"De la neuromylite optique aigu"-- in the same year. Neuromyelitis optica was called "Devic's disease" after Acchiote proposed this eponym in 1907. In his paper Devic named the disorder "neuromylite optique" or "neuroptico-mylite". The two cardinal questions he raised more than a century ago "Why such a peculiar localisation?" and "What is the intimate nature of the process?" still remain largely unanswered.1.

BIOLOGICAL AGE VERSUS CHRONOLOGICAL AGE IN LUNG CANCER PATIENTS Jameel F. Durrani, MBBS * ; Donald P. Jones, Chief, Cardiothoracic Surgery - HUMC; James Donahoo, Professor of Cardiothoracic Surgery UMDNJ; Jeffrey Gardner, Assistant Professor of Pediatrics; Abraham Aviv, Director, Hypertension Research Center - UMDNJ. UMDNJ- New Jersey Medical School, Wallington, NJ PURPOSE: To explore the relation between lung cancer and human aging. Telomeres are DNA binding proteins at the end of chromosomes. With age the telomeres undergo shortening or attrition in normal cells, represnting the biological clock of cell's life cycle. Patients presenting with lung cancer at a younger age than others may be genetically predisposed to this aging-related disease. HYPOTHESIS: The biological age of patients who present with lung cancer at an early age is more advanced than their chronological age would indicate. METHODS: After IRB approval, informed consents were obtained from 11 Patients male 9, female 2 ; undergoing lung cancer surgery. Patients were divided into two age groups, 50-60 years n 5 ; and 72-76 years n 6 ; . Tissue samples were collected from normal lung periphery of the removed lobe ; , skin and skeletal muscle during surgery. All samples were tested for telomere length. Muscle telomere length was used as a reference indicator representing telomere length at birth in each individual . Rate of telomere attrition was calculated by subtracting the telomeric length of each proliferating tissue skin and lung ; from non-proliferating tissue muscle ; and dividing by age of the individual . Student T-test non-paired ; was used and regression and analysis of variance for the rate of telomeric attrition as a function of age, was calculated. RESULTS and DISCUSSION: 1- Telomere length was consistently longer in the muscle than in lung and skin samples Figure 1 2- There was no significant difference in telomere length in muscle tissue in two age groups. p 0.2 3- Rate of telomere attrition was higher in the younger subjects than in the older subjects Figure 2, 3 ; . CONCLUSIONS: Telomere attrition rate that reflects biological aging ; in cancer patients is higher in middle age patients than elderly cancer patients. CLINICAL IMPLICATIONS: Results shed a new perspective on the relation between lung cancer and the biology of human aging. Large scale studies are needed to further explore the genetic risks to develop lung cancer.

Briefly, rats were killed by CO2 asphyxia, and hearts were quickly removed under sterile conditions. Ventricular tissue was isolated, minced, and digested using an enzymatic solution of collagenase 100 U ml ; and pancreatin 0.6 mg ml ; . Isolated CFs were pooled together, centrifuged, and resuspended in growth media that contained DMEM pH 7.4 ; , 5.5 mM D-glucose NG ; , 10% FBS, and 1% penicillin, streptomycin, and fungizone PSF ; . The CF suspension was plated onto tissue-culture dishes for 30 min; this allowed preferential attachment of CFs to culture dishes. After this incubation time, nonadherent cells were washed away, and the medium was replaced. CFs were maintained in growth media and incubated in a humidified atmosphere of 7% CO2 at 37C until fully confluent. Cells were passaged with 0.05% trypsinEDTA. All studies were performed with cells at passages 23. Treatment. CFs were grown to full confluence in growth media. CFs were rendered quiescent by serum starving for 24 h in DMEM supplemented with 0.1% heat-inactivated FBS and 1% PSF. CFs were then treated for 48 h with DMEM, 0.5% FBS, and 1% PSF at two different D-glucose concentrations 5.5 and 25 mM, NG and HG, respectively ; or with an osmotic control media 5.5 mM of D-glucose plus 19.5 mM of L-glucose ; . For the subsequent 24 h, CFs were treated using the same glucose concentrations in serum-deprived 0.1% heat-inactivated FBS ; medium. Drugs or their corresponding vehicles ; were added to each well during this time period. We used 1 M ANG II, 10 M losartan, and 45 M vitamin E.

At CANAL + Group, future accounts receivable in France have been sold partially without recourse to a bank, which has provided a corresponding facility of 305 million, at the preferential interest rate of Euribor all-in. The financing was established in May 1999 within the framework of a four-year contract but has subsequently been refinanced and structured through a special conduit, the shares of which are rated on the market. Under the terms of the contract, securitized accounts receivable represent four months revenues. The actual four-month revenues of CANAL + Group in France, at approximately 450 million, are significantly higher than the available facility. Vivendi Environnement, through some water business entities, has certain asset securitization facilities, which provided for the accelerated receipt of approximately 790 million of cash in 2001. Assets securitized under these facilities consist of accounts receivable. The balances outstanding on Cegetel Groups' and CANAL + Groups' asset securitization programs are recorded in the Consolidated Balance Sheet as long-term debt, those of Vivendi Environnement are off-balance sheet items. Vendor Financing In 1996 1997, Vivendi Universal, through Cegetel Group, entered into arrangements with several vendors to finance certain amounts payable for telecommunications and network equipment. These financing arrangements are based on promissory notes issued by Cegetel Group, which have been refinanced by financial institutions. They currently have an average maturity of two years, are unsecured and contain similar customary default and material adverse change clauses as standard bank loans. Although these financing arrangements enjoy favorable conditions in terms of interest rate, they are being utilized less by Cegetel Group. At December 31, 2001, Cegetel Group had 847 million of vendor financing outstanding 122 million due within one year ; , which was recorded as other liabilities in the Consolidated Balance Sheet. Long-term Borrowings Long-term borrowings recorded in the balance sheet primarily consist of standard bonds and bank loans, however, Vivendi Universal commonly uses convertible and or exchangeable debt, which represents long-term debt convertible exchangeable for common stock of another publicly traded company or Vivendi Universal itself. Generally, the bondholder may choose to receive either cash or the underlying security at settlement. Should the underlying security decline in value, this may result in the recording of an allowance related to the valuation of the security by Vivendi Universal and could result in the bondholder electing to receive cash at settlement. For further discussion of long-term borrowings see Item 18 -- Financial Statements --Note 5 Debt ; . Titres Subordonn Remboursable en Actions Prioritaires TSAR ; In December 2001, Vivendi Environnement, through its subsidiary Vivendi Environnement Financire de l'Ouest VEFO ; , issued obligated mandatorily redeemable security of subsidiary holding parent debentures for 300 million, with a maturity in December 28, 2006. As a result of its features, the TSAR is recorded as minority interest in the balance sheet. Generally, most long-term financing arrangements entered into by Vivendi Universal contain customary default and material adverse change clauses, which could lead to an acceleration of debt repayment. Some facilities provide for early redemption of certain debt if Vivendi Universal is downgraded below BBB- S&P ; or Baa3 Moodys ; . In addition, the total return swap agreements set up at the time of the sales of BSkyB and AOL Europe provide for an early unwind if Vivendi Universal is downgraded below BBB- S&P ; . Likewise, a downgrade would limit Vivendi Universal's access to the commercial paper market. Other facilities require certain coverage ratios to be met, for example EBITDA Net Financial Expense and Debt EBITDA. The asset securitization programs at Cegetel Group and CANAL + Group are subject to certain collection requirements and other measurement ratios. If these were to deteriorate, financing could be withdrawn or have to be renegotiated. As of March 28, 2002, we have a BBB rating from S&P and Baa2 rating from Moodys and are in compliance with all covenants. Contractual Obligations, Commercial Commitments and Contingent Liabilities - The following table summarizes information on Vivendi Universal's most significant contractual obligations and commercial commitments at December 31, 2001: - 26.

Dependence or habituation in susceptible persons-as addicts, alcoholics, severe psychoneurotics. After prolonged high dosage, drug should be withdrawn gradually to avoid withdrawal reactions and possible epileptiform seizures. Should drowsiness, ataxia, or visual disturbances occur, dose should be reduced. If symptoms persist, patients should not operate vehicles or dangerous machinery. Leukopenia, usually transient, has been reported following prolonged high dosage. Suicidal attempts should be treated with immediate gastric lavage and appropriate supportive therapy. Composition: meprobamate, Each scored multilayer tablet contains 150 mg. 75mg. ethoheptazine citrate, and 250 mg. aspirin.
Second- or third-line agents are used alone or sometimes in combination with first-line systemic drugs if those medications fail. Most are investigative and are generally less safe than first-line agents. Sulfasalazine. Sulfasalazine Azulfidine ; sometimes used for psoriasis. In one major analysis, sulfasalazine and methotrexate were the only agents proven to help patients with psoriatic arthritis. Many people, however, stop taking the drug because of common side effects that include headaches, gastrointestinal complaints, and rash. Benefits, if any, should be apparent in four to six weeks. Macrolides. Macrolides are agents that fight bacteria and also have immunosuppressant properties. Their actions are similar to those of cyclosporine. ; Some macrolides being studied for psoriasis include tacrolimus Prograf ; , pimecrolium, and sirolimus. In one study, for example, tacrolimus showed an 83% reduction in symptoms in patients with psoriasis who used the drug. Studies have been limited, however. Side effects of these agents are similar to those of cyclosporine. Pimecrolimus may specifically target the skin and so have fewer side effects. Some macrolides are also being studied as topical treatments.

Phase 1 RDEA119 data expected in second half of 2008 Presentation at the Seventh Annual JMP Securities Research Conference on May 21st canceled; webcast of corporate update scheduled during Ardea's Annual Stockholder Meeting on May 22nd at 9: 30 a.m. PT -SAN DIEGO, May 20, 2008 PRNewswire-FirstCall via COMTEX News Network -- Ardea Biosciences, Inc. Nasdaq: RDEA ; today announced that data was presented on the Company's lead mitogen-activated ERK kinase MEK ; inhibitor, RDEA119, demonstrating potent activity in mouse models of colitis. An oral presentation of the data was given at Digestive Disease Week DDW ; 2008 in San Diego, California. The MEK1 2 pathway is important in cell cycle regulation in inflammatory bowel disease, including ulcerative colitis and Crohn's disease. RDEA119 was shown to reduce damage to colonic tissue in two different mouse models of colitis, murine trinitrobenzene sulfonic acid TNBS ; colitis model and murine dextran sulfate sodium DSS ; colitis model. The beneficial effect observed equaled or exceeded that of sulfasalazine Azulfidine R , a therapy commonly used for acute and maintenance treatment of ulcerative colitis. "Despite the existing treatments, there are still significant unmet medical needs for inflammatory bowel disease. Blocking the MEK1 2 pathway appears to be a promising strategy in the ongoing search for a new generation of therapies aimed to treat ulcerative colitis and Crohn's disease, " said Barry D. Quart, PharmD, Ardea Biosciences' President and CEO. "These data further support the potential use of orally administered MEK inhibitors, such as RDEA119, for the treatment of inflammatory diseases." To support the development of RDEA119 in inflammatory diseases, a Phase 1 study in normal healthy volunteers is ongoing in which the Company is evaluating the pharmacokinetics, safety and tolerability of RDEA119, as well as its ability to inhibit inflammatory cytokines. Preliminary Phase 1 data have demonstrated that RDEA119 has a long half-life and favorable pharmacokinetic properties, allowing for once daily oral dosing. In addition, RDEA119 is currently in a Phase 1 study in advanced cancer patients. The doses being evaluated in the Phase 1 study in advanced cancer patients have achieved systemic exposure consistent with active doses in animal models of human tumors, without drug-related toxicity. The presentation is available on the Company website : ardeabio ; under the title "RDEA119, a Potent and Highly Selective MEK Inhibitor Ameliorates Murine Colitis." Corporate Update at Annual Stockholder Meeting Ardea will provide a corporate update at its Annual Stockholder Meeting. The presentation is scheduled for Thursday, May 22nd, at 9: 30 a.m. Pacific Time. To participate by telephone, please dial 877-440-5804 from the U.S. and Canada or + 1-719325-4854 for international callers. In addition, the live conference call is being webcast and can be accessed on the "News & Events" page of the Company's website at : ardeabio . A replay will also be available on Ardea's website for 14 days and by telephone through May 31, 2008. For the telephonic replay, please dial 888-203-1112 in the U.S. and Canada or + 1-719-457-0820 for international callers, and enter passcode 9342491 when prompted. About RDEA119 RDEA119, a non-ATP competitive, highly-selective MEK inhibitor for the treatment of inflammatory diseases and cancer, is the Company's lead compound from its MEK inhibitor research and development program. RDEA119 has shown potential as a potent inhibitor of MEK, which is believed to play an important role in inflammation, as well as cancer cell proliferation, apoptosis and metastasis. Preclinical and clinical results suggest that RDEA119 has favorable properties, including oral dosing, excellent selectivity and limited retention in the brain, which, in turn, may result in a reduced risk of central nervous system CNS ; side effects. The Company is also investigating a second generation MEK inhibitor, RDEA436, for potential use in inflammatory diseases and cancer. Preclinical data suggest that RDEA436 is a potent in vitro and in vivo inhibitor of MEK and may have favorable properties, such as low CNS penetration. In addition, RDEA436 has demonstrated a long half-life in a human micro-dose pharmacokinetic study, with the potential for once daily dosing in humans.
