MATERIALS AND METHODS N. meningitidis strains used in this study were recent isolates of both case and carrier strains from several widely separated geographical areas. Positive identification was made on the basis of cultural, morphological, and serological properties. Stock cultures were kept in less than the fifth passage from original isolation in a frozen state at -60 C. Table 1 gives the source and serological type of the six strains used in the bacteriocin typing of the meningococcus. The microorganisms were grown in Trypticase Soy Broth or on Mueller Hinton agar. Broth cultures were grown in a reciprocal shaker at 37 C. Plates and slants were incubated in a moist incubator 37 C ; with an atmosphere of 10% CO2 in air. Mitomycin C was added to broth cultures at a level of 1 , ug ml. Ultraviolet induction was carried out by exposing 3 ml of bacterial suspension of approximately 109 cells per milliliter to an ultraviolet lamp General Electric 15-w "germidical" lamp at 50 cm ; for 60 to 90 sec. A fivefold dilution was then made into fresh broth, and the cultures were shaken at 37 C. Bacteriocin activity was titered on agar plates by use of standard procedures 4 ; , and titers were expressed as the reciprocal of the highest dilution clearly showing a zone of lysis.
Introduction Multiple myeloma is an incurable hematologic malignancy that arises from the disordered growth of terminally differentiated plasma cells. The pathophysiologic basis for myeloma has been attributed to dysregulation of various autocrine growth factor loops, including those related to IL-6 and IL-1, 1, 2 as well as to perturbations in several survival signal transduction cascades, including the Ras Raf MAPK, PI3K Akt, JAK2 STAT3 and IKK I B NF- B pathways.3-5 Until recently, the mainstays of treatment for multiple myeloma consisted of steroids and cytotoxic drugs, 6 and, for those patients who are eligible, bone marrow transplantation.7 However, an improved understanding of the mechanisms underlying enhanced survival of myeloma cells has prompted the search for novel agents that might directly block myeloma-related survival pathways. Such efforts have recently led to the successful clinical development of the immunomodulatory derivatives of thalidomide IMiDs ; and the proteasome inhibitor Bortezomib Velcade ; , which have shown impressive activity in patients with progressive multiple myeloma.8, 9 Despite these advances, the search for additional new agents and effective strategies against myeloma remains a high priority. UCN-01 7-hydroxystaurosporine ; is a staurosporine derivative which was originally developed as an inhibitor of protein kinase C PKC ; , 10 but which was subsequently found to act as a potent inhibitor of Chk1.11 Disruption of checkpoint control is felt to be responsible for synergistic interactions between UCN-01 and various DNA-damaging agents, including mitomycin C and ara-C.12-14 More recently, UCN-01 has been shown to function as an inhibitor of PDK1 Akt.15 When administered in vitro, UCN-01 potently induces apoptosis in human leukemia cells, including those of myeloid and lymphoid origin.16, 17 Clinical trials of UCN-01 are currently underway, 18 and preliminary evidence of activity in combination with established cytotoxic agents has been reported in patients with lymphoid malignancies.19 Information concerning the activity of UCN-01 in myeloma is largely lacking, although our group recently described highly synergistic interactions between this agent and pharmacologic MEK mitogenactivated protein kinase kinase ; inhibitors in a variety of multiple myeloma cell lines.20 The NF- B transcription factor has been implicated in the control of diverse cellular processes including transformation, induction of proliferation, and suppression of apoptosis, cell invasion and angiogenesis among others in oncogenesis.21, 22 Under basal conditions, NF- B remains in the cytoplasm where it is bound to and inactivated by inhibitory subunits.23 Phosphorylation of e.g., by a multi-unit kinase consisting of IKK and IKK ; results in its proteasomal degradation, thereby permitting nuclear translocation of NF- B and transcriptional activation of target genes.24, 25 Because of the well-described association between NFdysregulation and multiple myeloma, 5 NF- B has become an attractive target for therapeutic intervention in this disease. Bay 11-7082, E ; -3- 4-methylphenylsulfonyl ; -2propenenenitrile, is an irreversible inhibitor of I B phosphorylation, which increases stabilization of I B and specifically blocks NF- B signaling.26 Furthermore, Bay 11-7082 has been shown to be a potent inducer of apoptosis in leukemia and lymphoma cells.27-29 Although Bay 11-7082 has not undergone clinical development, it represents a useful pharmacologic tool for dissecting the contribution of NF- B signaling to the survival of neoplastic cells, including those of hematopoietic origin. Currently, no information is available concerning the role that NF- B might play in regulating the apoptotic response of neoplastic hematopoietic cells to UCN-01. For several reasons, this issue may be particularly relevant to multiple myeloma, a disorder in which NF- B.

Is not closely coordinated with that of DNA. This is particularly evident during the period immediately preceding DNA replication at which time histones were synthesized at very low rates, whereas the HMG proteins attained about twothirds of their maximum rates of synthesis Figs. 2 and 5 ; . Incorporation into Cytoplasmic and Non-h&one Nuclear Proteins-In Fig. 6 are presented the results of experiments in which the incorporation of ["Hllysine into soluble cytoplasmic proteins and non-histone nuclear proteins was measured at various times after partial hepatectomy. At each time point, the specific activity of the non-histone nuclear proteins is about twice that of the cytoplasmic proteins, otherwise the curves are identical within the limits of experimental error. Comparison of Figs. 5 and 6 reveals that the incorporation curves for HMG proteins, which, as shown in the previous section, display significant differences from those of histones, are remarkably similar to those of the soluble cytoplasmic proteins and non-histone nuclear proteins. Effect of Inhibitors of DNA Synthesis on Incorporation into Histones and HMG Proteins-Hydroxyurea and mitomycin C at levels sufficient to depress incorporation of [14C]thymidine into DNA to 2 to 15% of control values reduced incorporation of ["Hllysine into histones to about 40% of control Fig. 7 ; . As demonstrated in Table III, incorporation into the three HMG proteins investigated decreased slightly or not at all under comparable conditions. Even when injecHMG 1 and mitotane.

| Mitomycin eyesDenominator Coding: A CPT procedure code to identify patients who received an arterial graft during coronary artery bypass graft surgery is required for denominator inclusion. CPT procedure codes: 33517-33519, 33521-33523, 33533-33536 RATIONALE: A major innovation has been the introduction of off-bypass CABG, which has reduced the postprocedure length of stay in some centers to between 2 and 3 days. In some centers, this has led to a total 3-month cost for single-vessel coronary bypass that is not significantly different from the total 3-month cost for angioplasty of single-vessel disease. Considering the favorable long-term patency of an internal mammary artery IMA ; graft to the LAD, the cost reductions possible with offbypass CABG may improve the relative cost-effectiveness of coronary bypass compared with either medical therapy or percutaneous techniques, particularly for symptomatic, proximal LAD disease. CLINICAL RECOMMENDATION STATEMENTS: Class I In every patient undergoing CABG, the left internal mammary artery IMA ; should be given primary consideration for revascularization of the left anterior descending LAD ; artery.

SsbAl does not. It behaves more like a DNA initiation mutant. dnaA does not induce phage or recA spontaneously or with nalidixic acid treatment 12 ; , but reacts normally towards UV induction 16 ; . ssbAl has been found to be defective in the induction of A prophage by UV or mitomycin C at 420C, but not at 300C 37 this was corroborated here under different conditions. We have also established that the amplification of recA protein synthesis in this mutant is inhibited at 420C with UV or mitomycin as inducer. Treatment with bleomycin caused an increase in recA synthesis and promoted phage induction under all conditions. Another example of opposite responses to different inducers was observed with recB or recC mutants, found to suppress recA protein synthesis amplification after nalidixic acid treatment 12 ; but to respond to bleomycin with increased synthesis 16 ; . These apparently conflicting responses can be reconciled when we consider the different pathways of producing the internal signal for SOS induction for each inducer 35 ; . For example, bleomycin produces nicks and gaps in the DNA nonenzymatically 22 ; , and it leads to a prompt induction. Nalidixic acid acts at the replication fork, and it seems to need recBC nuclease to promote gaps 12 ; . On the other hand, UV lesions in DNA can be removed by other nucleases in the absence of recBC, leading to formation of gaps. Our work with ssb mutants suggests that single-strand binding protein is required for the formation or maintenance, or both, of the gaps after UV treatment. There is in vitro evidence that SSB affects the activity of nucleases 23 ; . The ssbAl mutant should prove valuable in demonstrating whether this is also true in vivo. The possibility that SSB plays a role in protecting the single-strand regions is supported by our studies, which show enhanced DNA degradation in the mutants at the nonpermisive temperature. This is not conclusive, since the mutants are defective in recA induction, and there is a correlation between the level of this protein in the cell and the extent of DNA degradation 31 ; . The fact that we found no recA induction in the mutants up to 100 min after UV treatment and incubation at 420C, at a time when there is considerable DNA degradation, indicates that DNA degradation products alone are not sufficient to derepress the recA gene.

| Neurovascular explorations in distal femoral resections requiring neurovascular exploration of the popliteal space have traditionally necessitated a large posteromedial skin flap to permit adequate popliteal exposure. This has led to a high 15-25% ; wound complication rate. An "anterior" approach was developed to permit excellent visualization of the popliteal space and distal femur without the need for medial flaps, thus avoiding flap problems. The interval between the rectus femoris and vastus is developed proximally and distally, dividing the confluence of the rectus, medialis and intermedius tendons and continuing distally, remaining extraarticular in the interval between the capsule and the vastus medialis obliquus. The vastus medialis remains attached to the overlying skin, thus no flaps are created. The knee is flexed, exposing the entire popliteal space. Neurovascular exploration, distal femoral resection and endoprosthetic replacement are then easily performed. From 1999-2003 the Transadductor Approach has been employed in 21 distal femoral resections with endoprosthetic reconstruction. Diagnoses were osteosarcoma 12 ; , lymphoma 2 ; , and other 7 ; . Mean followup was 21 months. Three patients had small areas of necrosis resolved by one debridement. One patient had recurrent tumor, requiring amputation. One patient, an elderly diabetic, experienced significant wound breakdown. The Transadductor "Anterior" approach minimizes the incidence of flap necrosis. Medial skin flaps are not created. The key is the vastus medialis muscle remains attached thoughout its length to the overlying skin, therefore avoiding any potential sequealae. We have found this approach useful for almost any size distal femoral tumor, regardless of soft tissue component, and now utilize it routinely
Of stolons, recruitment of nematocytes specialized stinging cells ; in the area of contact, and tissue destruction 11 ; . To evaluate the effects of chimerism on Hydractinia growth, survival, and fusibility, we sought to generate chimeras consisting of a homogenous mixture of two donor cell lines. Early methods of producing Hydractinia chimeras involved grafting two larvae or blastomere halves along bisected surfaces 9, 10 ; . In this assay, chimeric animals generated from histocompatible partners yield normal colonies, whereas those generated from incompatible donors frequently separate at, during, or immediately after metamorphosis. It is unclear whether cell migration occurs in this embryonic model because the chimera separates along the line of fusion. The potential effects of systemic cell-to-cell interaction within the chimera are consequently not fully addressed. In the few cases that visible graft separation did not occur 9, 10 ; , clear documentation of chimerism was also impossible because genetic markers were unavailable. We sought to alleviate these difficulties by developing chimeras from well mixed cells and developing genetic markers to help characterize the fate of each cell line and determine the contribution of the alr gene complex to the stability of chimerism. Two sets of parents with identical alr genotype were used to generate histocompatible homotypic ; chimeras and two sets of parents with differing alr genotype were used to establish histoincompatible heterotypic ; chimeras Fig. 2 ; . In each case, a total of 18 embryos of each parental pair were dissociated in Ca2 Mg2 -free seawater and reaggregated to produce chimeric larvae. The larvae, whether generated from homotypic or heterotypic combination, successfully metamorphosed into single polyps. The polyps then generated juvenile colonies by asexual budding. Chimeric colonies derived from this assay were morphologically normal and some have been maintained for at least 6 months and molindone.

Also lymph node positivity as a predictor of adverse outcome. Jereczek-Fossa et al.20 treated 73 patients with recurrent endometrial carcinoma with radiotherapy, completed in 44 cases by an endovaginal boost of brachytherapy. With a median follow-up of 8.8 years, they reported 3-year and 5-year overall survival rates of 33% and 25%, respectively. Wylie et al. 21 administered radiation therapy for pelvic recurrence of endometrial cancer to 58 patients. The actuarial 5-year and 10-year overall survival rates were 53% and 41%, and the administration of a brachytherapy boost was significantly correlated with better survival. Our series of 30 consecutive patients with local1y recurrent endometrial carcinoma were prospectively treated with a schedule of concomitant 5-fluorouracil, mitomycin C and radiation. A "split course" treatment two courses of combined therapy with a 4-week interval ; was conceived, when the present study was designed, to prevent severe intestinal injury potentially related to previous abdominal surgery, sometimes involving an extensive lymphadenectomy. In fact, our toxicity data 6 patients showing acute grade 3 toxicity, 13.3% ; did not differ significantly from those reported by the previously mentioned exclusive radiotherapy trials18-20. It is now widely recognized that any prolongation of the treatment duration can favor tumor repopulation during the interruption of radiotherapy22, 23 . Anyway, in our analysis, we did not observe any significant correlation between treatment duration and response survival, and the lack of an association between split and prognosis has already been reported by Cummings et al.24. The overall response rate was 73.4%, 3-year local control and progression-free survival were 41.2% and 35.2%, respectively. Three-year survival was 46.8%. The median follow-up is apparently short, but it is noteworthy that most of the events were recorded during the first 24 months after the end of treatment. Therefore, patients who have survived free of disease after 3 years could reasonably feel cured by the treatment. The delivery of an endovaginal boost of brachytherapy seemed to improve overall survival, but it should be considered that it was reserved only for the selected subset of optimally responding patients. A significant correlation was observed in our series between pretreatment hemoglobin levels and local control P 0.0001 ; , progression-free survival P 0.002 ; and overall survival P 0.003 ; . These data confirm our previous reports25 and are similar to those reported in studies on radiotherapy of head and neck tumors26, 27 and in other studies on gynecological tumors28. Finally, the scoring system proved to be a simple and reproducible assessment tool which helped us to identify patients with better prognostic factors and a greater chance of responding to chemoradiation. It can be used in the near future to select gynecological patients who are good candidates for chemoradiation and consequently to recognize those patients whose clinical, pretreatment findings recommend more aggressive therapies.

The causes of about 95% of recurrent headache are migraine and "tension" headaches. Some people have both kinds, called a mixed-headache in some medical books. However, many neurologists now feel the mechanisms that cause them are the same. There are other notable forms of headache like cluster headaches but are uncommon and will not be discussed here. Most headaches can be diagnosed by your health care provider via history of symptoms and a physical exam. In the event a rarer cause of headache is suspected, such as a tumor or blood vessel problem, blood work, neurology referral, or even imaging by CT scanner or MRI may be needed for these "secondary" causes of headache. Typically, no scanning is warranted for uncomplicated migraine and "tension" headaches, and they are usually normal and are costly to the patient.
Interphasic blastomeres, the proportion of mononucleation, binucleation, and multinucleation did not differ among IVM groups. The difference was significant for the levels of mononucleation and multinucleation only when compared to the in vivo-matured groups P , 0.05 ; . A similar proportion of binuclear blastomeres existed among all the groups. Fewer embryos contained at least 50% mononuclear blastomeres in all IVM groups compared to embryos from in vivo-matured controls P , 0.05 ; Table 5 ; . Few embryos in each of the IVM groups had all mononuclear blastomeres: one 4-cell embryo in the 24-h PMC group 4% ; , none in the 48-h PMC group, one 7-cell embryo in the Control-CEO group 7% ; , and two embryos of 8- and 6-cells in the Control-DE group 12% ; . In contrast, 62% of embryos derived from in vivo-matured oocytes had all mononuclear blastomeres; of those, one was at the 4-cell stage, six at the 6-cell stage, three at the 8-cell stage, and one at the 9-cell stage. DISCUSSION Many questions remain about the mechanisms governing the final process of oocyte development. Therefore, how to devise IVM systems is not obvious on a rational basis. When oocytes are matured in vitro, quality is compromised, leading to defective embryonic development. In human IVF clinics, implantation rates from IVM cycles are decreased by half compared to those from IVF cycles, and IVM cycles present an increased incidence of early pregnancy loss. Studies of human and nonhuman primate oocytes ascribe some of the causes of failed embryonic development to faulty microtubular and chromatin organization and stability as well as to abnormal onset of embryonic genomic activation [27, 28]. It has been recognized that the deficient IVM outcome is mostly a result of the asynchrony between nuclear and cytoplasmic maturation. Supposedly, extending the period of GV-stage arrest in culture i.e., PMC ; might alleviate this asynchrony by allowing time for completion of cytoplasmic maturity [12, 24, 25, 2934] and mrv.

Synthesis of DDB protein occurs in UV-treated mammalian cells. To determine whether the magnitude of enhanced binding is the result of the amount of UV damage to cellular DNA, we examined extracts prepared 48 h after UV irradiation of cells with 6, 12, 18, and 24 J m2. There was a dose-dependent increase in the DDB activity of about 60, 120, 150, and 100%, respectively, above the levels in mock-treated cells gel not shown ; . Although a dose-dependent difference in DDB activity of about twofold seems to be relatively small, it was reproducible. These results suggest that the amount of DNA damage might be the major determinant in the magnitude of DDB protein complex induction in UV-irradiated cells. Because of cytotoxicity at greater doses, the dose of 10 to m2, which yields a colony-forming ability of about 10%, was used for further experiments. To gain further insight into the nature of the inducing signal, we pretreated cells with i ; mitomycin C, a UVmimetic compound which induces a mammalian SOS-like response 31 ; and triggers a pleiotropic effect known as the UV response 33 ii ; TPA, which induces a number of genes through responsive elements recognized by the TPAregulated cellular transcription factor AP-1 1 iii ; aphidicolin, a specific inhibitor of DNA polymerase alpha and delta; or iv ; low-serum growth medium, which arrests cell growth. Cell extracts were prepared 48 h after these treatments and tested for DDB protein. UV light, mitomycin C, and aphidicolin induced DDB protein by 90, 75, and 110%, respectively; TPA and 0.5% fetal calf serum medium had no effect. It thus appears that agents which directly damage.
