Abstract
OBJECTIVE The objective of this study is to investigate the impact of fluid status on perioperative outcomes of patients undergoing cytoreductive surgery (CRS) for advanced epithelial ovarian cancer (EOC). METHODS Patients undergoing CRS for stage III or IV EOC at a comprehensive cancer center from 12/2010 to 05/2015 were identified. Those who underwent upper abdominal procedures or colon resections were included. Demographic, perioperative, and 30-day complication data were collected. Perioperative weight change was utilized as a surrogate for fluid status. The time to diuresis (tD) was defined as the postoperative day the patient's weight began to downtrend. RESULTS One hundred ten patients were included. Median age was 62years and median BMI 25.8kg/m2. The majority (74.5%) were stage IIIC. At least 1 bowel resection was performed in 60 cases (54.5%). A median of 5381mL of crystalloid (range 1000-17,550mL) and 500mL of colloids (range 0-2783mL) was given intraoperatively. The median perioperative weight change was +7.3kg (range-0.9kg to +35.7kg). The median tD was 3days (range 1-17days). On univariate analysis, net positive fluid status was associated with unscheduled reoperation, anastomotic leak, surgical site infections (SSI), and length of stay >5days. On multivariate analysis, fluid status was independently associated with SSI (p=0.01). CONCLUSIONS Perioperative fluid excess is common in patients undergoing CRS for EOC and is independently associated with SSI.

Abstract
OBJECTIVE The study objective was to examine the safety and cost savings of selective cardiac surveillance (CS) during treatment with pegylated liposomal doxorubicin (PLD). METHODS A retrospective, dual institution study of women receiving PLD for the treatment of a gynecologic malignancy was performed. The study period was 2002-2014. At both institutions, a selective strategy for CS was implemented in which only high-risk women with a cardiac history or with symptoms suggestive of cardiac toxicity during PLD treatment underwent a cardiac evaluation. Patient demographics, clinical and treatment history were evaluated. Cost analyses were performed utilizing professional/technical fee rates for echocardiogram and multi-gated acquisition scan for each state. RESULTS PLD was administered in 184 women. The mean patient age was 62.7years, and 79% were treated for recurrent ovarian or peritoneal carcinoma. The median cumulative administered dose of PLD was 300mg/m(2); 24 received >550mg/m(2). The median follow-up time was 20months. Of the 184 patients, the majority (n=157, 85.3%) did not undergo either an initial cardiac evaluation or surveillance during or post-PLD treatment. Fifty-three patients considered high risk for anthracycline-induced cardiotoxicity underwent CS. Only three patients (1.6%) in the entire cohort developed CHF that was possibly related to PLD treatment; all had significant pre-existing cardiac risk factors. Selective instead of routine use of CS in the study population resulted in a cost savings of $182,552.28. CONCLUSION Utilizing cardiac surveillance in select women undergoing PLD treatment for gynecologic malignancies resulted in significant health care cost savings without adversely impacting clinical outcomes.

Abstract
The recent discovery of a large CP violating asymmetry in KL-->pi+pi-e+e- mode has prompted us to seach for the associated KL-->pi 0 pi 0 e+e- decay mode in the KTeV-E799 experiment at Fermilab. In 2.7 x 10(11) K(L) decays, one candidate event has been observed with an expected background of 0.3 event, resulting in an upper limit for the KL-->pi 0 pi 0 e+e- branching ratio of 6.6 x 10(-9) at the 90% C.L.

Abstract
We use K(L)'s in the 100-200 GeV energy range to produce 147 candidate events of the axial vector pair K1(1270)-K1(1400) in the nuclear Coulomb field of a Pb target and determine the radiative widths Gamma(K1(1400)-->K0+gamma)=280.8+/-23.2(stat)+/-40.4(syst) keV and Gamma(K1(1270)-->K0+gamma)=73.2+/-6.1(stat)+/-28.3(syst) keV. These first measurements appear to be lower than the quark-model predictions. We also place upper limits on the radiative widths for K(*)(1410) and K(*)(2)(1430) and find that the latter is vanishingly small in accord with SU(3) invariance in the naive quark model.

Abstract
We present a measurement of the charge asymmetry delta(L) in the mode K(L)-->pi(+/-)e(-/+)nu based on 298 x 10(6) analyzed decays. We measure a value of delta(L) = [3322+/-58(stat)+/-47(syst)]x10(-6), in good agreement with previous measurements and 2.4 times more precise than the current best published result. The result is used to place more stringent limits on CPT and DeltaS = DeltaQ violation in the neutral kaon system.

Abstract
We present the first measurement of the form factor ratios g(1)/f(1) (direct axial vector to vector), g(2)/f(1) (second class current), and f(2)/f(1) (weak magnetism) for the decay Xi(0)-->Sigma(+)e(-)nu macro(e) using the KTeV (E799) beam line and detector at Fermilab. From the Sigma(+) polarization measured with the decay Sigma(+)-->p pi(0) and the e(-)-nu; correlation, we measure g(1)/f(1) to be 1.32+/-(0.21)(0.17)(stat)+/-0.05(syst), assuming the SU(3)(f) (flavor) values for g(2)/f(1) and f(2)/f(1). Our results are all consistent with exact SU(3)(f) symmetry.

In addition, we set the 90% confidence upper limit on the combined branching ratios for the lepton flavor violating decays K(L)-->e(+/-)e(+/-)mu(-/+)mu(-/+) at B(K(L)-->e(+/-)e(+/-)mu(-/+)mu(-/+))< or =1.23x10(-10), assuming a uniform phase space distribution.

Abstract
We report on the analysis of the rare decay K(L)-->mu(+)mu(-)gamma the 1997 data from the KTeV experiment at Fermilab. A total of 9327 candidate events are observed with 2.4% background, representing a factor of 40 increase in statistics over the current world sample. We find that B(K(L)-->mu(+)mu(-)gamma) = (3.62 +/- 0.04(stat) +/- 0.08(syst)) x 10(-7). The form factor parameter alpha(K*) is measured to be alpha(K*) = -0.160(+0.026)(-0.028). In addition, we make the first measurement of the parameter alpha from the D'Ambrosio-Isidori-Portolés form factor, finding alpha = -1.54 +/- 0.10. In that model, this alpha measurement limits the Cabibbo-Kobayashi-Maskawa parameter rho>-0.2.

Abstract
We have studied the rare weak radiative hyperon decay Xi degrees -->Sigma degrees gamma in the KTeV experiment at Fermilab. We have identified 4045 signal events over a background of 804 events. The dominant Xi degrees -->Lambdapi degrees decay, which was used for normalization, is the only important background source. An analysis of the acceptance of both modes yields a branching ratio of B(Xi degrees -->Sigma degrees gamma)/B(Xi degrees -->Lambdapi degrees ) = (3.34+/-0.05+/-0.09)x10(-3). By analyzing the final state decay distributions, we have also determined that the Sigma degrees emission asymmetry parameter for this decay is alpha(XiSigma) = -0.63+/-0.09.

Abstract
We have performed studies of the K(0)(L)-->pi(+)pi(-)gamma direct emission ( DE) and inner Bremsstrahlung ( IB) vertices, based on data collected by KTeV during the 1996 Fermilab fixed target run. We find a(1)/a(2) = -0.737+/-0.034 GeV2 for the DE form-factor parameter in the rho-propagator parametrization, and report on fits of the form factor to linear and quadratic functions as well. We concurrently measure gamma(K(0)(L)-->pi(+)pi(-)gamma,E(*)(gamma)>20 MeV)/gamma(K(0)(L)-->pi(+)pi(-)) = (20.8+/-0.3)x10(-3), and a K(0)(L)-->pi(+)pi(-)gamma DE/(DE+IB) branching ratio of 0.683+/-0.011.

Abstract
We report on a search for the decay KL-->pi(0)e+e- carried out by the KTeV/E799 experiment at Fermilab. This decay is expected to have a significant CP violating contribution and the measurement of its branching ratio could support the Cabibbo-Kobayashi-Maskawa mechanism for CP violation or could point to new physics. Two events were observed in the 1997 data with an expected background of 1.06+/-0.41 events, and we set an upper limit B(KL-->pi(0)e+e-)<5.1 x 10(-10) at the 90% confidence level.

Abstract
Adenylosuccinate lyase (ASL) from Bacillus subtilis has been crystallized and structural analysis by X-ray diffraction is in progress. ASL is a 200-kDa homotetramer that catalyzes two distinct steps of de novo purine biosynthesis leading to the formation of AMP and IMP; both steps involve the beta-elimination of fumarate. A single point mutation in the human ASL gene has been linked to mental retardation with autistic features. In addition, ASL plays an important role in the bioprocessing of anti-HIV therapeutics. B subtilis ASL, which shares 30% sequence identity and 70% sequence similarity with human ASL, has been crystallized and data to 3.3 A have been collected at 100 K. The space group is P6(1)22 or P6(5)22 with a = b = 129.4 A; the length of the c-axis varies between 275 and 290 A, depending on the crystal. An analysis of solvent content indicates a dimer in the asymmetric unit, although a self-rotation function and an analysis of native Pattersons failed to identify unambiguously the location of any noncrystallographic symmetry axes. Structure determination by isomorphous replacement is in progress.

Abstract
The Ser/Thr phosphoprotein phosphatases (PPases) display similarities in amino acid sequence and biochemical properties. Most members of this family require transition metal ions for activity. The smallest family member, the bacteriophage lambda PPase (lambda-PPase), has been successfully overexpressed in Escherichia coli, purified, and characterized (Zhuo, S., Clemens, J.C., Hakes, D.J., Barford, D., and Dixon, J. E. (1993) J. Biol. Chem. 268, 17754-17761). Site-directed mutagenesis has now been employed to define amino acid residues in lambda-PPase required for metal ion binding and catalysis. Conservative amino acid substitutions at residues Asp20, His22, Asp49, His76, and Glu77 affected lambda-PPase catalysis and metal ion binding, whereas substitutions at residues Arg53 and Arg73 affected catalysis and substrate binding. Each of these residues is invariant in all phosphoprotein phosphatases, suggesting that these residues may play important roles in binding and catalysis in all of the PPases. Computer-assisted sequence alignment further revealed that lambda-PPase residues Asp20, His22, Asp49, His76, Arg53, and Arg73 lie within three larger regions of PPase sequence identity with the consensus sequence (DXH-(approximately 25)-GDXXD-(approximately 25)-GNHD/E). This motif can be found in a wide variety of phosphoesterases unrelated to the PPases and defines structural and catalytic features utilized by a diverse group of enzymes for the hydrolysis of phosphate esters.

Abstract
Adenylosuccinate adenosine 5'-monophosphate lyase (EC 4.3.2.2; ASL) catalyzes two distinct reactions in adenosine 5'-monophosphate (AMP) biosynthesis. A S413P mutation in ASL segregates with mental retardation in an affected family (Stone, R. L., Aimi, J., Barshop, B. A., Jaeken, J., Van den Berghe, G., Zalkin, H., and Dixon, J. E. (1992) Nature Genet. 1, 59-63). ASL and S413P ASL have been expressed, purified, and kinetically characterized. Lowering the Escherichia coli growth temperature to 25 degrees C and the concentration of inducer, isopropyl-1-thio-beta,D-galactopyranoside, to 40 microM was necessary for synthesis of soluble, tetrameric enzymes. The recombinant enzymes were purified to homogeneity using anion exchange chromatography followed by chromatography on Blue 2A Sepharose. At pH 7.0 and 25 degrees C, the kcat for cleavage of 5-amino-4-imidazole-N-succinocarboxamide ribotide (SAI-CAR) by ASL was 90 s-1 with a Km of 2.35 microM. The kcat for adenylosuccinate (SAMP) cleavage was 97 s-1 with a Km of 1.79 microM. The catalytic mechanism involved one general base catalyst (pK alpha = 6.4) and one general acid catalyst (pK alpha = 7.5). ASL follows an ordered uni-bi reaction mechanism with fumarate released first. 5-Amino-4-imidazolecarboxamide ribotide (AICAR) and AMP were competitive with SAICAR and SAMP (Ki[AICAR] = 11.3 microM; Ki[AMP] = 9.2 microM), whereas fumarate inhibited noncompetitively (Kii = 2.3 mM, Kis = 2.8 mM). The competitive inhibition by AICAR and AMP suggests a single active site that binds both SAICAR and SAMP. The kinetic constants at pH 7.0, 25 degrees C and the kcat/Km versus pH profiles for ASL and S413P ASL were very similar. These results are consistent with S413P being a structural rather than a catalytic defect.

Abstract
We have examined the molecular basis of three cases of severe mental retardation with autistic features in one family. A point mutation in a purine nucleotide biosynthetic enzyme, adenylosuccinate lyase (ASL), segregates with the disorder. The affected children are homozygous for the point mutation while the parents and all four unaffected children are heterozygous. The point mutation is absent in control subjects. The point mutation results in a Ser413Pro substitution which leads to structural instability of the recombinant mutant enzyme, and this instability lowers ASL levels in lymphocytes. These observations suggest that the instability of ASL underlies the severe developmental disorder in the affected children, and that mutations in the ASL gene may result in other cases of mental retardation and autistic features.

Abstract
We report the molecular cloning, nucleotide (nt) sequence and chromosomal assignment of the Saccharomyces cerevisiae gene GLP1. This gene encoded a 15-kDa protein that was synthesized at a low level during growth on glucose and was induced ninefold upon glucose deprivation. When glucose withdrawal was accompanied by the addition of fatty acids the induction was enhanced an additional two- to threefold. The GLP1 gene product was identified as a soluble protein and purified using a combination of gel permeation and ion exchange chromatography. Using oligodeoxyribonucleotides as hybridization probes we have isolated the GLP1 gene and sequenced the single, long open reading frame which is 351 nt in length and is not interrupted by introns. The GLP1 gene directed the transcription of a 700-nt mRNA in response to glucose deprivation. The accumulation of the mRNA was further enhanced twofold by the addition of oleate. We have localized the GLP1 gene to S. cerevisiae chromosome VI.

Abstract
The effect of retinoic acid (RA) on the adipose conversion of 3T3 cells has been studied. Differentiation of 3T3-L1 cells was initiated by addition of 0.5 mM methylisobutylxanthine, 0.3 microM dexamethasone and 10 micrograms/ml insulin (MDI) to confluent monolayers of preadipocytes for 48 h. During this time, the cells underwent DNA replication and cell division prior to the expression of adipose specific genes. RA administration had no apparent effect on the rate or extent of cell growth, cell division, or DNA replication. However, RA treatment concomitant with MDI addition inhibited triacylglycerol accumulation (I0.5 = 6 nM) and the accumulation of the differentiation-dependent mRNAs encoding the adipocyte lipid-binding protein (ALBP) and stearoyl-CoA desaturase 1 (SCD1). No inhibition occurred with RA addition either prior to or after MDI treatment. Runoff transcription revealed that the inhibitory effects of RA occurred at the level of transcription and were persistent. Cells treated with RA during the MDI regimen did not appreciably transcribe ALBP or SCD1 mRNAs several days following RA withdrawal. The effects of RA were specific for differentiation-dependent transcripts: 10(-6) M RA did not inhibit expression of the mRNAs encoding beta-tubulin or glutamine synthase. Examination of immediate-early transcription factor expression during the MDI regimen revealed that RA mediated an elevated, prolonged expression of c-Jun mRNA accompanied by diminished expression of c-Fos and Jun-B mRNAs. Given the previously demonstrated role of transcription factor AP-1 in ALBP gene expression, our results suggest that the initiation of expression of this and other adipocyte-specific genes during adipose conversion is regulated by the relative composition of transcription factor AP-1.

Abstract
The toxicity of toxic shock syndrome (TSS) toxin-1 (TSST-1) was evaluated in female, specific pathogen-free rabbits and conventional rabbits. Results after intravenous injections of TSST-1 given to both types of rabbits indicated that specific pathogen-free rabbits were resistant to the lethal effects observed in conventional rabbits. Lethality could be prevented by simultaneous administration of polymyxin B, and analysis of serum before and after dosing confirmed that dosing with TSST-1 resulted in circulating endotoxin. Analysis of sera from humans with TSS showed that endotoxin was present in acute-phase sera but not in convalescent-phase sera. These observations suggest that endogenous endotoxin contributes to rabbit susceptibility to TSST-1 and may play a role in human TSS.

Abstract
Five yearling wether sheep were maintained on total intravenous, fat-free feeding for periods in excess of 4 weeks. Analysis of plasma total lipid, neutral lipid, and phospholipid fatty acid patterns showed a decrease in linoleic acid during the first week, after which levels tended to stabilize. Rate of decrease in linoleic acid content of plasma phospholipids of two sheep was different. Changes in nonessential fatty acids were variable. 5,8,11- and 8,11,14-Eicosatrienoic acids were not detected in any of the sheep.

Abstract
The effect of azathioprine on macromolecular biosynthesis was studied in mouse spleen cells cultured in vitro. The rate of incorporation of (3)H-thymidine, (3)H-uridine, and (14)C-leucine into acid-insoluble material was used to measure deoxyribonucleic acid, ribonucleic acid, and protein synthesis. Results indicate that azathioprine inhibited nucleic acid and protein synthesis at levels which did not decrease cell viability.
