Abstract
Biliary atresia (BA) is a devastating cholestatic disorder of infants that presents during the first several months after birth due to an idiopathic obstruction to the bile flow. Without prompt diagnosis, Kasai portoenterostomy, and deliberate follow-ups, the resulting cholestasis leads to progressive hepatic failure. Oxidative stress is an abnormal phenomenon inside cells or tissues caused by a disturbance in the reactive oxygen species (ROS). We aimed to measure perioperative ROS in BA patients.Data are presented as median (25th, 75th percentiles). We evaluated 15 BA patients (age 55 [48, 69] days) and measured ROS; serum superoxide dismutase (SOD), urinary 8-iso prostaglandin F2α (8-iso-PGF2α) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) preoperatively and 30 days later to compare values with serum liver function tests and histologic grades of liver cholestasis. For compared BA patients, 4 normal subjects as control group (age 55 [27, 75] days) measured ROS and serum liver function tests.In BA patients, the preoperative serum SOD was 6.1 IU/mL (4.7, 7.2), urinary 8-iso-PGF2α was 1969 pg/mg Cre (1697, 2374), and urinary 8-OHdG was 37.1 ng/mg Cre (33.1, 53.7). At the postoperative day 30, the serum SOD was 5.2 IU/mL (4.2, 6.7), urinary 8-iso-PGF2α was 1761 pg/mg Cre (1256, 3036), and urinary 8-OHdG was 42.1 ng/mg Cre (29.65, 72.64). In ROS, there were no significant differences between the 2 periods. In control group, urinary 8-iso-PGF2α was significantly lower than that in preoperative BA patient group. However, other ROS were not significant differences between control group and BA patient group. The concentration of urinary 8-iso-PGF2α was positively correlated with total bilirubin and direct bilirubin levels (preoperatively: r = 0.6921, P = .0042 and r = 0.6639, P = .007, postoperatively: r = 0.6036, P = .0172 and r = 0.6464, P = .0092, respectively). The preoperative ROS were not correlated with histologic grades of liver cholestasis. Various factors such as liver inflammation, lipid malabsorption, and tissue disorders due to jaundice might affect the antioxidant activity and elevated urinary 8-iso-PGF2α. However, at least until 30 days later, urinary 8-OHdG as oxidative DNA damage might persist after the operation whether the cholestasis improved or not.

Abstract
BACKGROUND The aim of this study was to determine the frequency and nature of pediatric blunt chest-abdominal injuries (BCAIs) and to summarize their management, ranging from non-operative management (NOM), with or without angioembolization (AE), to surgical treatment. METHODS This retrospective study included patients admitted to our hospital for BCAIs from January 1996 to December 2017. The age, injury pattern, organs of injury, outcome, and treatment were summarized. RESULTS One hundred and thirty-two patients (98 males, 34 females, mean age 7.68 years ± 3.58, range 1-15 years) were included in the study. Their injuries resulted from motor-vehicle traffic incidents (n = 60), single-bicycle injuries (n = 16), falls (n = 33), sports (n = 10), assault (n = 6), abuse (n = 3), and others (n = 4). There were no injured organs in 31 cases, while there were 130 injured organs in 101 cases, including the liver (n = 42), spleen (n = 35), lung (n = 23), kidney (n = 13), intestine (n = 10), pancreas (n = 5), and adrenal gland (n = 2). Angiography (AG) was performed in 20 cases, and NOM with AE was performed in 16 cases, including 17 organs (liver injury [n = 9], splenic injury [n = 5], and kidney injury [n = 4]). Surgical treatment was performed in eight cases (splenic injury in one, pancreas injury in one, and intestinal injury in six). NOM without AE was performed in the other cases. CONCLUSIONS The management of organ injury must take into consideration the management of integrated bleeding. It is recommended that children with severe organ injury are treated in dedicated trauma centers in which AE is available.

Abstract
Abstract A 39-year-old woman with systemic lupus erythematosus (SLE) developed severe acute pancreatitis during a well-controlled disease stage. Treatment with intraarterial injections of antipancreatic enzyme and a small amount of prednisone (20 mg/day) led to remission of the pancreatitis. Disease activity of the SLE did not flare up throughout the course of this treatment. The development of severe acute pancreatitis in SLE is rare. We discuss the cause of pancreatitis in SLE, and whether corticosteroids may induce or improve pancreatitis.

Abstract
PURPOSE Several studies have reported the herbal medicine Inchinko-to (ICKT) to have an antifibrotic effect which thus leads to an improvement of hepatic injury. However, there are still few reports of its use in the treatment of cholestatic liver disorder. The aim of this study was to clarify whether the administration of ICKT will ameliorate hepatic fibrosis and injury in cholestatic rats. MATERIALS AND METHODS We performed bile duct ligation on 7-week-old male cholestatic Wistar rats and assigned them to one of three groups according to the method of treatment: (1) the SHAM group, (2) the NT-group (non-treatment group), and (3) the T-group (treatment-group). Rats in the T-group were orally administered ICKT (TJ-135) at a dose of 1 g/kg/day and were killed on the 17th postoperative day. We subsequently investigated the levels of fibrosis and various clinical markers through measurement of the following: serum levels of AST and ALT; tissue transforming growth factor-beta 1 (TGF-beta1); tissue inhibitor metalloprotease-1 mRNA (TIMP-1 mRNA) through real-time PCR analysis; and Azan staining and immunohistochemical staining of alfa-smooth muscle actin (alfa-SMA) to evaluate the degree of fibrosis. RESULTS The levels of serum AST, serum ALT, and TGF-bata1 in the T-Group were significantly lower than those in the NT-Group. In addition, staining of Azan and alfa-SMA in the T-Group was significantly lower than those in the NT-Group. CONCLUSION ICKT may help reduce hepatic fibrosis and injury by controlling stellate cell activation.

Abstract
Fecoflowmetry (FFM) has been introduced to simulate natural anorectal evacuation. So far, few reports have described the effect of the herbal medicine Daikenchuto (DKT) on impaired anorectal motor function. The aim of this pilot study was to assess anorectal motor function by FFM in postoperatively impaired patients with an anorectal malformation (ARM) before and after administration of DKT. Six postoperative patients with ARM (mean age, 7.8 years) who complained of intractable constipation with soiling in spite of administration of magnesia as a laxative were assessed over an extended period. These patients received 0.3 g/kg/d of DKT for an average of 128 days. Evacuative rate and maximum fecal stream flow were seen to increase significantly after administration of DKT when compared with values before administration of DKT. In conclusion, DKT had a favorable clinical effect on anorectal motor function in postoperative patients with ARM.

Abstract
The nutritional condition of perioperative patients affects the results of surgical treatment. For a better prognosis, surgeons must always consider patients' nutritional status preoperatively. After first assessing the nutritional status, a regimen to improve and/or maintain proper nutrition should be selected taking symptoms and treatment procedure into consideration. Peripheral parenteral nutrition provides limited energy. If patients' nutritional status requires improvement and they must fast for a long-term, total parenteral nutrition should be administered. Parenteral nutrition is nonphysiologic therapy and may have severe complications. During the administration of enteral nutrition via a gastrointestinal fistula or nasogastric tube, vomiting and incorrect infusion due to the improper positioning of the feeding tube may occur. When administering nutrition therapy via a gastrostomy or intestinal fistula, care must be taken to determine the appropriate dose and infusion rate. To provide suitable nutritional therapy, our knowledge of the various options available must be expanded.

Abstract
PURPOSE Several studies have reported green tea catechin to have both antifibrotic and anti-oxidative effects. The goal of this study was to evaluate the effect of green tea cathechin therapy in hepatic tissue injury using cholestatic rats with bile duct ligation. MATERIALS AND METHODS We performed bile duct ligation on cholestatic seven-week-old male Wistar rats and classified them into three groups according to the method of treatment. The groups comprised the SHAM group, the NT-group (no-treatment-group), and the T-group (treatment-group). The rats were orally administered green tea catechin at a dose of 50mg/kg/day and were sacrificed on the 17th postoperative day. We subsequently investigated the levels of fibrosis and antioxidant activity associated with various clinical markers. We evaluated the serum AST and ALT levels and performed immunohistochemical analyses for 4-hydroxynonenal (4-HNE), 8-oxo-2'deoxyguanosine (8-OHdG) and transforming growth factor-beta1 (TGF-beta1). We also evaluated the levels of activator protein-1 m-RNA (AP-1 m-RNA) and tissue inhibitor metalloproteinase-1 m-RNA (TIMP-1 m-RNA) by Real Time PCR. Finally, we performed Azan staining and immunohistochemical staining of alpha-smooth muscle actin (alpha-SMA) to evaluate the degree of fibrosis. RESULTS The values of serum AST, serum ALT, AP-1 m-RNA, alpha-SMA, TGF-beta1, 4-HNE, and 8-OHdG in the T-Group were significantly lower than those in NT-Group. Therefore, the administration of green tea catechin might have suppressed the oxidative stress, controlled the stellate cell activation and consequently reduced the fibrosis. CONCLUSION Green tea catechin may reduce hepatic fibrosis by suppressing oxidative stress and controlling the transcription factor expression involved in stellate cell activation.

Abstract
BACKGROUND AND PURPOSE Alogliptin, a highly selective dipeptidyl peptidase-4 (DPP-4) inhibitor, enhances incretin action and pioglitazone enhances hepatic and peripheral insulin actions. Here, we have evaluated the effects of combining these agents in diabetic mice. EXPERIMENTAL APPROACH Effects of short-term treatment with alogliptin alone (0.01%-0.1% in diet), and chronic combination treatment with alogliptin (0.03% in diet) and pioglitazone (0.0075% in diet) were evaluated in db/db mice exhibiting early stages of diabetes. KEY RESULTS Alogliptin inhibited plasma DPP-4 activity up to 84% and increased plasma active glucagon-like peptide-1 by 4.4- to 4.9-fold. Unexpectedly, alogliptin alone lacked clear efficacy for improving glucose levels. However, alogliptin in combination with pioglitazone clearly enhanced the effects of pioglitazone alone. After 3-4 weeks of treatment, combination treatment increased plasma insulin by 3.8-fold, decreased plasma glucagon by 41%, both of which were greater than each drug alone, and increased plasma adiponectin by 2.4-fold. In addition, combination treatment decreased glycosylated haemoglobin by 2.2%, plasma glucose by 52%, plasma triglycerides by 77% and non-esterified fatty acids by 48%, all of which were greater than each drug alone. Combination treatment also increased expression of insulin and pancreatic and duodenal homeobox 1 (PDX1), maintained normal beta-cell/alpha-cell distribution in islets and restored pancreatic insulin content to levels comparable to non-diabetic mice. CONCLUSIONS AND IMPLICATIONS These results indicate that combination treatment with alogliptin and pioglitazone at an early stage of diabetes improved metabolic profiles and indices that measure beta-cell function, and maintained islet structure in db/db mice, compared with either alogliptin or pioglitazone monotherapy.

Abstract
BACKGROUND AND PURPOSE Many post-operative patients with biliary atresia (BA) suffer from liver dysfunction, such as chronic inflammation even without jaundice after a Kasai's hepatic portoenterostomy. METHODS The presence and degree of oxidative stress were evaluated in the post-operative patients with BA. Twelve outpatients who underwent a Kasai's hepatic portoenterostomy were evaluated. The active oxygen products, the rate of bioantioxidant, the markers of oxidative stress, and the degree of hepatic oxidative stress were examined by immunohistochemical staining of biopsied specimens. RESULTS All of the oxidative stress markers in the post-operative patients with BA increased in comparison to those in the controls. Moreover, 8-OHdG immunohistochemical staining was positive in 84+/-4.8% in hepatic cells in the portal area in the post-operative patients with BA. CONCLUSION The post-operative patients with BA were under increased oxidative stress, even if their liver dysfunction was mild without jaundice. Antioxidant therapy might be necessary to decrease of oxidative stress in the post-operative patients with BA.

Abstract
Split notochord syndrome (SNS) is an extremely rare anomaly. This report presents the case of a male infant with SNS associated with congenital ileal atresia and a dorsal enteric cyst communicating to the retroperitoneal isolated ceca with a vesical fistula. Dorsal fistulography and vesicography were useful and essential for the detailed study of the topology in this patient. The embryological mechanism and etiologic theories are discussed with a review of 19 cases reported in the literature.

Abstract
Perioperative chemotherapy (CT) and chemoradiotherapy are widely used for advanced esophageal cancer. We evaluated the chemosensitivity of patients displaying recurrent esophageal cancer after esophagectomy with perioperative CT. From the database at National Cancer Center Hospital in Tokyo, we extracted recurrent esophageal cancer cases after perioperative CT and evaluated the effectiveness of the first CT against the recurrent disease according to the duration between termination of the original perioperative CT and recurrence with treatment-free intervals (TFIs) <or=6 and >6 months. Systemic CT for their recurrent disease was performed for 30 esophageal cancer patients after perioperative CT. All patients received 5-fluorouracil and cisplatin as perioperative CT, with relapses occurring at TFIs <or=6 months in 11 patients (eight received platinum-containing regimens and three received docetaxel for their recurrent disease) and >6 months in 19 patients (all received platinum-containing regimens). The response rate of patients experiencing a recurrence at TFIs <or=6 and >6 months was 0 and 37% (P = 0.029), the median progression-free survival was 2.8 and 4.8 months (log-rank P = 0.001) and the median overall survival was 6.1 and 10.2 months (log-rank P = 0.012), respectively. Recurrence at the TFI <or=6 months could represent resistance to CT, so regimens may need to be altered depending on a patient's specific TFI.

Abstract
We compared the efficacy and the safety of a carboplatin plus etoposide regimen (CE) vs split doses of cisplatin plus etoposide (SPE) in elderly or poor-risk patients with extensive disease small-cell lung cancer (ED-SCLC). Eligibility criteria included: untreated ED-SCLC; age ⩾70 and performance status 0–2, or age <70 and PS 3. The CE arm received carboplatin area under the curve of five intravenously (IV) on day 1 and etoposide 80 mg m−2 IV on days 1–3. The SPE arm received cisplatin 25 mg m−2 IV on days 1–3 and etoposide 80 mg m−2 IV on days 1–3. Both regimens were given with granulocyte colony-stimulating factor support in a 21–28 day cycle for four courses. A total of 220 patients were randomised. Median age was 74 years and 74% had a PS of 0 or 1. Major grade 3–4 toxicities were (%CE/%SPE): leucopenia 54/51, neutropenia 95/90, thrombocytopenia 56/16, infection 7/6. There was no significant difference (CE/SPE) in the response rate (73/73%) and overall survival (median 10.6/9.9 mo; P=0.54). Palliation scores were very similar between the arms. Although the SPE regimen is still considered to be the standard treatment in elderly or poor-risk patients with ED-SCLC, the CE regimen can be an alternative for this population considering the risk–benefit balance.

Abstract
We experienced a very rare case of a gastrointestinal perforation due to multiple ileal polyps. The patient was a 2-day-old boy who weighed 1,430 g at birth. At neonatal day 2 subdiaphragmatic free air was noted and an emergency operation was performed. During surgery a distended ileum approximately 5 cm in size was found approximately 40 cm distal from the ileocecum, and a perforation was discovered in the distended portion of the intestine. Approximately 8 cm of the ileum was resected, including the distended portion of the intestine, and an ileostomy was performed. Examination of the resected specimen revealed three pedunculated polyps with a perforation proximal to the polyps.

Abstract
We report results from a study of events with a double-Pomeron exchange topology produced in p p collisions at sqrt[s]=1800 GeV. The events are characterized by a leading antiproton and a large rapidity gap on the outgoing proton side. We find that the differential production cross section agrees in shape with predictions based on Regge theory and factorization, and that the ratio of double-Pomeron exchange to single diffractive production rates is relatively unsuppressed as compared to the O(10) suppression factor previously measured in single diffractive production.

Abstract
We report the observation of a narrow state decaying into J/psipi+pi- and produced in 220 pb(-1) of p p-bar collisions at =1.96 Tesqaure root of sV in the CDF II experiment. We observe 730+/-90 decays. The mass is measured to be 3871.3+/-0.7(stat)+/-0.4(syst) MeV/c2, with an observed width consistent with the detector resolution. This is in agreement with the recent observation by the Belle Collaboration of the X(3872) meson.

Abstract
We report on a search for direct Kaluza-Klein graviton production in a data sample of 84 pb(-1) of ppmacr; collisions at sqrt[s]=1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and one or two high energy jets. We compare the data with the predictions from a (3+1+n)-dimensional Kaluza-Klein scenario in which gravity becomes strong at the TeV scale. At 95% confidence level (C.L.) for n=2, 4, and 6 we exclude an effective Planck scale below 1.0, 0.77, and 0.71 TeV, respectively.

Abstract
The aims of this study were to determine the normal values of plasma diamine oxidase (pDAO) activity in children and to examine the influence of several factors (nutritional management, dietary fiber, and chemotherapy) on pDAO activity. The activity of pDAO was measured in 138 healthy children with minor surgical conditions such as inguinal hernia or undescended testis. In order to define normal values patients were subdivided into 5 groups according to age. Next, changes in pDAO activity under different nutritional conditions were studied in 14 patients with adhesive ileus. The influence of chemotherapeutic drugs on pDAO activity was also studied in 19 neuroblastoma patients. I. The normal values of pDAO activity at year < 1, 1 < or = years < 3, 3 < or = years < 6.6 < or = years < 12, 12 < or = years were 6.65 +/- 1.75, 7.70 +/- 2.29, 6.53 +/- 1.68, 5.85 +/- 1.87, 5.06 +/- 1.84 units/l, respectively. II. The pDAO activities in patients with ileus were 4.73 +/- 1.02 (total parenteral nutrition), 6.84 +/- 1.18 (enteral, nutrition), 7.62 +/- 0.67 (soluble dietary fiber added enteral nutrition) and 8.82 +/- 1.26 units/l (oral feeding). The difference in pDAO activity at enteral or oral feeding vs. total parenteral nutrition was significant (p < .0001). III. The pDAO activity decreased significantly and remained low during the first 4 days after cyclophosphamide administration in neuroblastoma patients. The preadministration of dietary fiber inhibited the influence of cyclophosphamide. Plasma DAO activity was greatly influenced by nutritional management and administration of dietary fiber and/or cyclophosphamide. Plasma DAO activity may be a sensitive marker of intestinal function in children.

Abstract
We present the results of a search for pair production of scalar top quarks (t(1)) in an R-parity violating supersymmetry scenario in 106 pb(-1) of pp collisions at square root of s=1.8 TeV collected by the Collider Detector at Fermilab. In this mode each t(1) decays into a tau lepton and a b quark. We search for events with two tau's, one decaying leptonically (e or mu) and one decaying hadronically, and two jets. No candidate events pass our final selection criteria. We set a 95% confidence level lower limit on the t(1) mass at 122 GeV/c(2) for Br(t(1)-->tau b)=1.

Abstract
Nesidioblastosis is a rare disorder in pediatric surgery. It is caused by hypertrophy and hyperplasia of the islands of Langerhans, and can lead to persistent hyperinsulinemic hypoglycemia. If appropriate treatment is delayed there is a high risk of the development of cerebral palsy, impaired mental development, epilepsy or other forms of irreversible brain damage, so early detection and early treatment to stabilize serum glucose levels is essential. Initial treatment consists of nutritional management with administration of an adequate amount of calories along with drug therapy using diazoxide. In cases that are resistant to drug therapy a subtotal pancreatectomy is performed. Conventional recommended practice has been to perform a 95% pancreatectomy, however this can lead to the onset of diabetes due to abnormal pancreatic endocrine function. We report here a case of nesidioblastosis in which we performed an 85% pancreatectomy. Postoperative clinical course has been excellent, with no recurrence or impaired glucose tolerance during the four years since the operation.

Abstract
We report on measurements of differential cross sections dsigma/dp(T) for prompt charm meson production in ppmacr; collisions at sqrt[s]=1.96 TeV using 5.8+/-0.3 pb(-1) of data from the CDF II detector at the Fermilab Tevatron. The data are collected with a new trigger that is sensitive to the long lifetime of hadrons containing heavy flavor. The charm meson cross sections are measured in the central rapidity region |y|</=1 in four fully reconstructed decay modes: D0-->K-pi(+), D(*+)-->D0pi(+), D+-->K-pi(+)pi(+), D(+)(s)-->phipi(+), and their charge conjugates. The measured cross sections are compared to theoretical calculations.

Abstract
We report on a search for a high mass, narrow width particle that decays directly to emu, etau, or microtau. We use approximately 110 pb(-1) of data collected with the Collider Detector at Fermilab from 1992 to 1995. No evidence of lepton flavor violating decays is found. Limits are set on the production and decay of sneutrinos with R-parity violating interactions.

Abstract
We report a measurement of the fraction of events with a large pseudorapidity gap deltaeta within the pseudorapidity region available to the proton dissociation products X in p+p-->p+X. For a final state p of fractional momentum loss xi(p) and 4-momentum transfer squared t(p) within 0.06<xi(p)<0.09 and |t(p)|<1.0 [0.2] GeV2 at sqrt[s]=1800 [630] GeV, the fraction of events with deltaeta>3 is found to be 0.246+/-0.001 (stat)+/-0.042 (syst) [0.184+/-0.001 (stat)+/-0.043 (syst)]. Our results are compared with gap fractions measured in minimum bias pp collisions and with theoretical expectations.

Abstract
We have searched for pair production of the supersymmetric partner of the top quark (stop) in 107 pb(-1) of pp collisions at square root of s=1.8 TeV collected by the Collider Detector at Fermilab (CDF). Each stop is assumed to decay into a lepton, bottom quark, and supersymmetric neutrino. Such a scenario would give rise to events with two leptons, two hadronic jets, and a substantial imbalance of transverse energy. No evidence of such a stop signal has been found. We exclude stop masses in the region (80</=m(t)</=135 GeV/c(2)) in the mass plane of stop versus sneutrino.

Abstract
We present a search for associated production of the Upsilon(1S) and a vector boson in 83 pb(-1) of ppmacr; collisions at sqrt[s]=1.8 TeV collected by the CDF experiment in 1994-1995. We find no evidence of the searched signal in the data, and set upper limits to the production cross sections.

Abstract
We report a search for the production of long-lived charged massive particles in a data sample of 90 pb(-1) of square root[s]=1.8 TeV pp collisions recorded by the Collider Detector at Fermilab. The search uses the muonlike penetration and anomalously high ionization energy loss signature expected for such a particle to discriminate it from backgrounds. The data are found to agree with background expectations, and cross section limits of O(1) pb are derived using two reference models, a stable quark and a stable scalar lepton.

Abstract
We report the results of a search for a W' boson produced in pp; collisions at a center-of-mass energy of 1.8 TeV using a 106 pb(-1) data sample recorded by the Collider Detector at Fermilab. We observe no significant excess of events above background for a W' boson decaying to a top and bottom quark pair. In a model where this boson would mediate interactions involving a massive right-handed neutrino (nu(R)) and have standard model strength couplings, we use these data to exclude a W' boson with mass between 225 and 536 GeV/c(2) at 95% confidence level for M(W')>>M(nu(R)) and between 225 and 566 GeV/c(2) at 95% confidence level for M(W')<M(nu(R)).

Abstract
The exclusive gammaE(T) signal has a small standard model cross section and is thus a channel sensitive to new physics. This signature is predicted by models with a superlight gravitino or with large extra spatial dimensions. We search for such signals at the Collider Detector at Fermilab, using 87 pb(-1) of data at square root [s]=1.8 TeV, and extract 95% C.L. limits on these processes. A limit of 221 GeV is set on the scale |F|(1/2) in supersymmetric models. For 4, 6, and 8 extra dimensions, model-dependent limits on the fundamental mass scale M(D) of 0.55, 0.58, and 0.60 TeV, respectively, are found. We also specify a "pseudo-model-independent" method of comparing the results to theoretical predictions.

Abstract
The purpose of the present study was to examine the effect of multiple application of dentin bonding agent to the adhesive surface on the marginal integrity of resin composite. The effect of multiple applications was evaluated by measuring the wall-to-wall polymerization contraction gap and by SEM observation. Multiple application of dentin bonding agent was found to prevent formation of the contraction gap. Although monomer penetration into the enlarged collagen network has been widely discussed as the possible mechanism of the dentin bonding agent and dentin primer, the true detailed mechanism of the dentinal bonding agent and dentin primer should be consistently explained by the prevention of monomer diffusion into the dentin and water contamination of the adhesive interface.

Abstract
We present the results of a search in pp collisions at sqrt[s] = 1.8 TeV for anomalous production of events containing a photon and a lepton (e or mu), both with large transverse energy, using 86 pb(-1) of data collected with the Collider Detector at Fermilab during the 1994-1995 collider run at the Fermilab Tevatron. The presence of large missing transverse energy (E(T)), additional photons, or additional leptons in these events is also analyzed. The results are consistent with standard model expectations, with the possible exception of photon-lepton events with large E(T), for which the observed total is 16 events and the expected mean total is 7.6+/-0.7 events.

Abstract
The purpose of the present study was to investigate the efficacy of dentin adhesives and to examine acid resistance in primary and permanent teeth. The efficacy of dentin adhesives was evaluated by SEM observation and by measuring the wall-to-wall polymerization contraction gap and dentin hardness before and after conditioning. The detailed mechanism of dentin bonding was the same in both primary and permanent teeth.

Abstract
We report on measurements of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) differential cross sections (d(2)sigma/dp(T)dy)(/y/<0.4), as well as on the Upsilon(1S) polarization in p p macro collisions at square root of s = 1.8 TeV using a sample of 77+/-3 pb(-1) collected by the collider detector at Fermilab. The three resonances were reconstructed through the decay Upsilon-->mu(+)mu(-). The measured angular distribution of the muons in the Upsilon(1S) rest frame is consistent with unpolarized meson production.

Abstract
We report a measurement of the diffractive structure function F(D)(jj) of the antiproton obtained from a study of dijet events produced in association with a leading antiproton in pp collisions at sqrt[s] = 630 GeV at the Fermilab Tevatron. The ratio of F(D)(jj) at sqrt[s] = 630 GeV to F(D)(jj) obtained from a similar measurement at sqrt[s] = 1800 GeV is compared with expectations from QCD factorization and other theoretical predictions. We also report a measurement of the xi ( x-Pomeron) and beta ( x of parton in Pomeron) dependence of F(D)(jj) at sqrt[s] = 1800 GeV. In the region 0.035<xi<0.095, /t/<1 GeV2, and beta<0.5, F(D)(jj)(beta,xi) is found to be of the form beta(-1.0+/-0.1)xi(-0.9+/-0.1), which obeys beta-xi factorization.

Abstract
We present the first general search for new heavy particles, X, which decay via X --> WZ0 --> e(nu)+jj as a function of M(X) and Gamma(X) in pp collisions at square root[s] = 1.8 TeV. No evidence is found for production of X in 110 pb(-1) of data collected by the Collider Detector at Fermilab. General cross section limits are set at the 95% C.L. as a function of mass and width of the new particle. The results are further interpreted as mass limits on the production of new heavy charged vector bosons which decay via W' --> WZ0 in an extended gauge model as a function of the width, Gamma(W'), and mixing factor between the W' and the standard model W bosons.

Abstract
We report a study of the decays B0 --> J/psiK(*)0pi(+)pi(-), which involve the creation of a uu or dd quark pair in addition to a b -->c(cs) decay. The data sample consists of 110 pb(-1) of pp collisions at square root[s] = 1.8 TeV collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995. We measure the branching fractions to be B(B0 --> J/psiK(*0)pi(+)pi(-)) = (6.6 +/- 1.9 +/- 1.1)x10(-4) and B(B0 --> J/psiK0pi(+)pi(-)) = (10.3 +/- 3.3 +/- 1.5)x10(-4). Evidence is seen for contributions from psi(2S)K(*)0, J/psiK0rho(0), J/psiK(*+)pi(-), and J/psiK1(1270).

Abstract
We have performed a search for gluinos (g) and scalar quarks (q) in a data sample of 84 pb(-1) of pp collisions at square root[s] = 1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and three or more jets, a characteristic signature in R-parity-conserving supersymmetric models. The analysis has been performed "blind," in that the inspection of the signal region is made only after the predictions from standard model backgrounds have been calculated. Comparing the data with predictions of constrained supersymmetric models, we exclude gluino masses below 195 GeV/c2 (95% C.L.), independent of the squark mass. For the case m(q) approximately m(g), gluino masses below 300 GeV/c2 are excluded.

Abstract
We report a measurement of the strong coupling constant, alpha(s)(MZ), extracted from inclusive jet production in pp collisions at square root[s] = 1800 GeV. The QCD prediction for the evolution of alpha(s) with jet transverse energy ET is tested over the range 40<ET<450 GeV using ET for the renormalization scale. The data show good agreement with QCD in the region below 250 GeV. The value of alpha(s) at the mass of the Z0 boson averaged over the range 40<ET<250 GeV is found to be alpha(s)(MZ) = 0.1178+/-0.0001(stat)+0.0081(-0.0095)(expt. syst). The associated theoretical uncertainties are mainly due to the choice of renormalization scale ((+6%)(-4%)) and input parton distribution functions (5%).

Abstract
We present results of the first search for like-sign dilepton ( e(+/-)e(+/-), e(+/-)mu(+/-), mu(+/-)mu(+/-)) events associated with multijets and large missing energy using 106 pb(-1) of data in pp macro collisions at square root of s = 1.8 TeV collected during 1992-1995 by the CDF experiment. Finding no events that pass our selection, we examine pair production of gluinos (tilde g) and squarks (tilde q) in a constrained framework of the minimal supersymmetric standard model. At tan beta = 2 and mu = -800 GeV/c(2), we set 95% confidence level limits of M(tilde g)>221 GeV/c(2) for M(tilde g) approximately M(tilde q), and M(tilde q)>168 GeV/c(2) for M(tilde q)>>M(tilde g), both with small variation as a function of mu.
