Abstract
In this study, we examined the accuracy and rapidity of drug susceptibility determination using clinical isolates of MRSA with the fully automated rapid identification susceptibility testing system RAISUS S4. Ninety eight MRSA strains were used and the time until methicillin resistance was determined was analyzed by both of the standard method (18-hr method) and the rapid method. Five strains (5.1%) were determined to be methicillin-sensitive in MPIPC by rapid method only while all strains were determined to be resistant in CFX. The average methicillin resistance determination time was 7.0/5.0 hr for MPIPC, 6.3/5.0 hr for CFX, and 6.3/5.0 hr for the combination of MPIPC and CFX by the standard/rapid method, with the rapid method being significantly shorter (Wilcoxon's signed rank sum test, p<0.01). Strains determined to be methicillin-sensitive by MPIPC tended to have a longer time to methicillin resistance by the standard method, but this effect was much less pronounced for the rapid method using CFX. Methicillin resistance determination by the rapid method using RAISUS S4 enables rapid detection of MRSA without false-susceptible results, which may lead to early and appropriate treatment.

Abstract
Exophiala species cause chromoblastomycosis, mycetoma, and phaeohyphomycosis, which are occasionally fatally in immunocompromised patients. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) provides rapid and accurate examination of isolated bacteria and some fungal isolates, but the preparation method for filamentous fungi is complicated. In this study, 31 clinical isolates of Exophiala spp. in Japan were identified by MALDI-TOF MS with a library enriched by adding data. To simplify the sample preparation method, two modified methods were compared with the standard method for filamentous fungi. The agar cultivation sample preparation method reduced the time required for liquid culture and was considered suitable for clinical use. In 30 of 31 clinical isolates of Exophiala spp., the species identified by MALDI-TOF MS with the highest score matched the species identified by sequencing the internal transcribed spacer region. Exophiala dermatitidis, E. lecanii-corni, and E. oligosperma were identified above the genus level, while E. jeanselmei and E. xenobiotica were often not identified at the species level. The identification scores tended to be lower for less-registered strains in the in-house library. It is suggested that library enrichment and the modified preparation method may facilitate early diagnosis of rare fungal infections by Exophiala spp. in clinical laboratories using MALDI-TOF MS.

Abstract
A hemin-requiring Proteus vulgaris small-colony variant (SCV) was isolated from a urine culture. This isolate was grown on 5% sheep blood agar but not on modified Drigalski agar. The single nucleotide substitution was found in the SCV of the hemC gene (c.55C > T), and this substitution caused a nonsense mutation (p.Gln19Ter). Porphyrin test results showed that the biosynthesis of δ-aminolevulinic acid stopped up to porphobilinogen and not pre-uroporphyrinogen due to a mutation in the hemC gene. To our knowledge, this is the first report of hemin-requiring P. vulgaris.

Abstract
Legionella longbeachae is a Legionella bacteria often detected in soil, and is known as a rare cause of Legionella infections in Japan. In addition, detection of this Legionella species is often overlooked due to negative results from Legionella urinary antigen tests, which could lead to errors in the therapeutic approach. An 80-year-old woman was admitted to our hospital because of fever and dyspnea. Her blood tests showed elevated white blood cells, increased C-reactive protein and transaminases, and hyponatremia. Chest computed tomography showed dense consolidation in the right lung. We diagnosed Legionella pneumonia because the Legionella urinary antigen test was positive on the day after her admission. The patient was intubated and mechanically ventilated on the third day of hospitalization, because of respiratory failure. However, her condition did not improve and she died on the 10th day after admission. After her death, L. longbeachae was detected from sputum culture from her tracheal tube, and was diagnosed as the causative organism of her pneumonia. L. longbeachae infection reportedly rarely produces positive urinary antigen test results. Our experience suggests that the urinary antigen test using Ribotest Legionella might be able to detect Legionella spp. other than L. pneumophila.

Abstract
The aim of this study was to compare the effectiveness of the gene-panel next-generation sequencing (NGS) strategy versus the clinical-based gene Sanger sequencing for the genetic diagnosis of autoinflammatory diseases (AIDs). Secondary goals were to describe the gene and mutation distribution in AID patients and to evaluate the impact of the genetic report on the patient's medical care and treatment. Patients with AID symptoms were enrolled prospectively and randomized to two arms, NGS (n = 99) (32-55 genes) and Sanger sequencing (n = 197) (one to four genes). Genotypes were classified as 'consistent/confirmatory', 'uncertain significance' or 'non-contributory'. The proportion of patients with pathogenic genotypes concordant with the AID phenotype (consistent/confirmatory) was significantly higher with NGS than Sanger sequencing [10 of 99 (10·1%) versus eight of 197 (4·1%)]. MEFV, ADA2 and MVK were the most represented genes with a consistent/confirmed genotype, whereas MEFV, NLRP3, NOD2 and TNFRSF1A were found in the 'uncertain significance' genotypes. Six months after the genetic report was sent, 54 of 128 (42·2%) patients had received effective treatment for their symptoms; 13 of 128 (10·2%) had started treatment after the genetic study. For 59 of 128 (46%) patients, the results had an impact on their overall care, independent of sequencing group and diagnostic conclusion. Targeted NGS improved the diagnosis and global care of patients with AIDs.

Abstract
Background:Telemedicine has found wider application in chronic diseases for encouraging tight home-monitoring in order to improve patients’ outcome (Smolen et al. 2017).In previous studies, a high feasibility and high patient-satisfaction rate was found as well as the evidence for a superior or equal effectiveness of telemedicine compared to the standard face-to-face approach, however the results were weakened by some methodological biases and wide heterogeneity of interventions, thus preventing to draw definitive conclusions (Piga et al. 2017; Najm, Gossec, et al. 2019).Objectives:In rheumatoid arthritis (RA), telemedicine may allow a tight control of disease activity while reducing hospital visits. We developed a smartphone application connected with a physician’s interface to monitor RA patients. We aimed to assess the performance of this e-Health solution in comparison with routine practice in the management of patients with RA.Methods:A 6-month pragmatic, randomized, controlled, prospective, clinical trial was conducted in RA patients with high to moderate disease activity starting a new Disease Modifying Anti-Rheumatic Drug (DMARD) therapy. Two groups were established: “connected monitoring” and “conventional monitoring”. The primary outcome was the number of physical visits between baseline and 6 months. Secondary outcomes included adherence, satisfaction, changes in clinical, functional, and health status scores (SF-12).Results:Of the 94 randomized patients, 89 completed study: 44 in the “conventional monitoring” arm and 45 in the “connected monitoring” arm. The total number of physical visits between baseline and 6 month was significantly lower in the “connected monitoring” group (0.42 ± 0.58 versus 1.93 ± 0.55; p<0.05). No differences between groups were observed in the clinical and functional scores. A better quality of life for SF-12 subscores (Role-Physical, Social-Functioning and Role-Emotional) were found in the “connected monitoring” group.Conclusion:According to our results, a connected monitoring reduces the number of physical visits while maintaining a tight control of disease activity and improving quality of life in patients with RA starting a new treatment.References:[1] Najm, Aurelie, Laure Gossec, Catherine Weill, David Benoist, Francis Berenbaum, and Elena Nikiphorou. 2019. “Mobile Health Apps for Self-Management of Rheumatic and Musculoskeletal Diseases: Systematic Literature Review.”JMIR MHealth and UHealth7 (11): e14730.https://doi.org/10.2196/14730.[2] Piga, Matteo, Ignazio Cangemi, Alessandro Mathieu, and Alberto Cauli. 2017. “Telemedicine for Patients with Rheumatic Diseases: Systematic Review and Proposal for Research Agenda.”Seminars in Arthritis and Rheumatism47 (1): 121–28.https://doi.org/10.1016/j.semarthrit.2017.03.014.[3] Smolen, Josef S, Robert Landewe, Johannes Bijlsma, Gerd Burmester, Katerina Chatzidionysiou, Maxime Dougados, Jackie Nam, et al. 2017. “EULAR Recommendations for the Management of Rheumatoid Arthritis with Synthetic and Biological Disease-Modifying Antirheumatic Drugs: 2016 Update.”Annals of the Rheumatic Diseases76 (6): 960–77.https://doi.org/10.1136/annrheumdis-2016-210715.Disclosure of Interests:None declared

Abstract
Patients post DLGG surgery use attentional resources to compensate deficit. Functional plasticity occurs at secondary regions at distance from the lesion. Picture naming requires the integration of multiple resting-state networks. The right hemisphere plays also an important role in language processing. A whole brain approach with clinical input in case of lesion is the way forward.
The dynamic connectome perspective states that brain functions arise from the functional integration of distributed and/or partly overlapping networks. Diffuse low-grade gliomas (DLGG) have a slow infiltrating character. Here we addressed whether and how anatomical disconnection following DLGG growth and resection might interfere with functional resting-state connectivity, specifically in relation to picture naming. Thirty-nine native French persons with a left DLGG were included. All underwent awake surgical resection of the tumor using direct brain electrostimulation to preserve critical eloquent regions. The anatomical disconnectivity risk following the DLGG volume and the resection, and the functional connectivity of resting-state fMRI images in relation to picture naming were evaluated prior to and three months after surgery. Resting-state connectivity patterns were compared with nineteen healthy controls. It was demonstrated that picture naming was strongly dependent on the semantic network that emerged from the integration and interaction of regions within multiple resting-state brain networks, in which their specific role could be explained in the light of the broader resting-state network they take part in. It emphasized the importance of a whole brain approach with specific clinical data input, during resting-state analysis in case of lesion. Adaptive plasticity was found in secondary regions, functionally connected to regions close to the tumor and/or cavity, marked by an increased connectivity of the right and left inferior parietal lobule with the left inferior temporal gyrus. In addition, an important role was identified for the superior parietal lobe, connected with the frontal operculum, suggesting functional compensation by means of attentional resources in order to name a picture via recruitment of the frontoparietal attention network.

Abstract
AIMS To assess the prevalence and characteristics of medication errors at hospital admission and discharge in people with Type 1 and Type 2 diabetes, and identify potential risk factors for these errors. METHODS This prospective observational study included all people with Type 1 (n = 163) and Type 2 diabetes (n = 508) admitted to the Diabetology-Department of the University Hospital of Montpellier, France, between 2013 and 2015. Pharmacists conducted medication reconciliation within 24 h of admission and at hospital discharge. Medication history collected from different sources (patient/family interviews, prescriptions/medical records, contact with community pharmacies/general practitioners/nurses) was compared with admission and discharge prescriptions to detect unintentional discrepancies in medication indicating involuntary medication changes. Medication errors were defined as unintentional medication discrepancies corrected by physicians. Risk factors for medication errors and serious errors (i.e. errors that may cause harm) were assessed using logistic regression. RESULTS A total of 322 medication errors were identified and were mainly omissions. Prevalence of medication errors in Type 1 and Type 2 diabetes was 21.5% and 22.2% respectively at admission, and 9.0% and 12.2% at discharge. After adjusting for age and number of treatments, people with Type 1 diabetes had nearly a twofold higher odds of having medication errors (odds ratio (OR) 1.72, 95% confidence interval (CI) 1.02-2.94) and serious errors (OR 2.17, 95% CI 1.02-4.76) at admission compared with those with Type 2 diabetes. CONCLUSIONS Medication reconciliation identified medication errors in one third of individuals. Clinical pharmacists should focus on poly-medicated individuals, but also on other high-risk people, for example, those with Type 1 diabetes.

Abstract
BACKGROUND AND PURPOSE The aim of our study was to examine the effect sizes of different cognitive function determinants in middle and early old age. METHODS Cognitive functions were assessed in 11 711 volunteers (45 to 75 years old), included in the French CONSTANCES cohort between January 2012 and May 2014, using the free and cued selective reminding test (FCSRT), verbal fluency tasks, digit-symbol substitution test (DSST) and trail making test (TMT), parts A and B. The effect sizes of socio-demographic (age, sex, education), lifestyle (alcohol, tobacco, physical activity), cardiovascular (diabetes, blood pressure) and psychological (depressive symptomatology) variables were computed as omega-squared coefficients (ω2 ; part of the variation of a neuropsychological score that is independently explained by a given variable). RESULTS These sets of variables explained from R2 = 10% (semantic fluency) to R2 = 26% (DSST) of the total variance. In all tests, socio-demographic variables accounted for the greatest part of the explained variance. Age explained from ω2 = 0.5% (semantic fluency) to ω2 = 7.5% (DSST) of the total score variance, gender from ω2 = 5.2% (FCSRT) to a negligible part (semantic fluency or TMT) and education from ω2 = 7.2% (DSST) to ω2 = 1.4% (TMT-A). Behavioral, cardiovascular and psychological variables only slightly influenced the cognitive test results (all ω2 < 0.8%, most ω2 < 0.1%). CONCLUSION Socio-demographic variables (age, gender and education) are the main variables associated with cognitive performance variations between 45 and 75 years of age in the general population.

Abstract
We developed a novel chromogenic method, Penta-well test, which enables the rapid detection and classification of β-lactamases in clinical Enterobacteriaceae isolates. This test is based on a combination of nitrocefin and 3 β-lactamase inhibitors specific to classes A, B, and/or C, with nitrocefin hydrolysis by β-lactamases being assessed by optical density measurements at 490 nm. When the cutoff value for each β-lactamase class was determined (0.09, 0.4, and 0.55 for class A, class B, and class C β-lactamase producers, respectively), the sensitivity and specificity of classification were 93.5% and 68.8% for class A, 93.8% and 100% for class B, and 86.7% and 100% for class C, respectively. Moreover, this method allowed accurate β-lactamase classification in 20 of 23 (87.0%) isolates producing plural class of β-lactamases. Thus, the Penta-well test can provide information that would be useful in the accurate detection and classification of β-lactamases produced by causative bacteria.

Abstract
Statin use may be limited by muscle side effects. Although incompletely understood to date, their pathophysiology may involve oxidative stress and impairments of mitochondrial function and of muscle Ca(2+) homeostasis. In order to simultaneously assess these mechanisms, 24 male healthy volunteers were randomized to receive either simvastatin for 80 mg daily or placebo for 8 weeks. Blood and urine samples and a stress test were performed at baseline and at follow-up, and mitochondrial respiration and Ca(2+) spark properties were evaluated on a muscle biopsy 4 days before the second stress test. Simvastatin-treated subjects were separated according to their median creatine kinase (CK) increase. Simvastatin treatment induced a significant elevation of aspartate amino transferase (3.38±5.68 vs -1.15±4.32 UI/L, P<0.001) and CK (-24.3±99.1±189.3 vs 48.3 UI/L, P=0.01) and a trend to an elevation of isoprostanes (193±408 vs 12±53 pmol/mmol creatinine, P=0.09) with no global change in mitochondrial respiration, lactate/pyruvate ratio or Ca(2+) sparks. However, among statin-treated subjects, those with the highest CK increase displayed a significantly lower Vmax rotenone succinate and an increase in Ca(2+) spark amplitude vs both subjects with the lowest CK increase and placebo-treated subjects. Moreover, Ca(2+) spark amplitude was positively correlated with treatment-induced CK increase in the whole group (r=0.71, P=0.0045). In conclusion, this study further supports that statin induced muscular toxicity may be related to alterations in mitochondrial respiration and muscle calcium homeostasis independently of underlying disease or concomitant medication.

Abstract
UNLABELLED Peripubertal artistic gymnasts display elevated areal bone mineral density at various bone sites, despite delayed menarche and a high frequency of menstrual disorders, factors that may compromise bone health. The concomitant improvement in femoral bone geometry and strength suggested that this type of physical activity might have favourable clinical impact. INTRODUCTION The purpose of this study is to evaluate the effect of artistic gymnastics (GYM) on areal bone mineral density (aBMD), femoral bone geometry and bone markers and its relationship with the osteoprotegerin (OPG)/rank-ligand (RANKL) system in peripubertal girls. METHODS Forty-six girls (age 10-17.2 years) were recruited for this study: 23 elite athletes in the GYM group (training 12-30 h/week, age at start of training 5.3 years) and 23 age-matched (± 6 months; leisure physical activity ≤ 3 h/week) controls (CON). The aBMD at whole body, total proximal femur, lumbar spine, mid-radius and skull was determined using dual-X-ray absorptiometry. Hip structural analysis (HSA software) was applied at the femur to evaluate cross-sectional area (CSA, cm(2)), cross-sectional moment of inertia (CSMI, cm(4)), and the section modulus (Z, cm(3)) and buckling ratio at neck, intertrochanteric region and shaft. Markers of bone turnover and OPG/RANKL levels were also analysed. RESULTS GYM had higher (5.5-16.4%) non-adjusted aBMD and adjusted aBMD for age, fat-free soft tissue and fat mass at all bone sites, skull excepted and the difference increased with age. In the three femoral regions adjusted for body weight and height, CSA (12.5-18%), CSMI (14-18%), Z (15.5-18.6%) and mean cortical thickness (13.6-21%) were higher in GYM than CON, while the buckling ratio (21-27.1%) was lower. Bone markers decreased with age in both groups and GYM presented higher values than CON only in the postmenarchal period. A similar increase in RANKL with age without OPG variation was observed for both groups. CONCLUSION GYM is associated not only with an increase in aBMD but also an improvement in bone geometry associated with an increase in bone remodelling. These adaptations seem to be independent of the OPG/RANKL system.

Abstract
BACKGROUND Inherited factor (F)VII deficiency is the commonest of the rare bleeding disorders, with a wide set of hemorrhagic features. Other than for the severe clinical forms (for which treatment guidelines are well defined), consistent recommendations regarding perioperative replacement management do not exist for mild and asymptomatic FVII-deficient patients. OBJECTIVES The present study aimed to evaluate the influence of bleeding history, FVII procoagulant activity levels (FVII:C) and the type of surgical procedure on the management of inherited FVII-deficient patients before surgery. PATIENTS One hundred and fifty-seven surgical procedures, performed without replacement therapy, in 83 unrelated FVII-deficient patients (median FVII:C=5%, range 0.6%-35%) were analyzed. RESULTS The overall bleeding rate was 15.3%. We found a significant relationship between previous deep traumatic hematomas and bleeding at surgery, although relationships with previous common epistaxis, easy bruising and menorrhagia were not significant. The receiver-operating characteristic (ROC) curve analysis performed on the first 83 procedures allowed us to define a cut-off value of 7% with a sensitivity of 87% (negative predictive value: 94%). To enhance the sensitivity, and to take into account the potential variation resulting from non-standardized FVII:C measurements, we would suggest applying a threshold of 10%. CONCLUSION We have proposed recommendations for the perioperative management of FVII-deficient patients based on FVII:C levels, a thorough bleeding history and the type of surgery involved. By applying these recommendations, minor procedures that risk only external or controlled hemorrhage can be performed in asymptomatic or mildly affected adults, even those with FVII:C levels below 10%.

Abstract
BACKGROUND AND PURPOSE Intracranial stent placement assists in the coiling of wide-neck aneurysms and aids in reconstructing and protecting the parent artery. In this study, we analyze our experience in the use of the Neuroform system. MATERIALS AND METHODS Records of patients treated with a Neuroform stent from June 2003 to September 2007 were retrieved from a data base for analysis of population characteristics, occurrence of complications, and acute and midterm angiographic results. RESULTS Sixty-eight patients harboring 76 aneurysms located primarily in the anterior circulation were treated. There were 5 cases (6.6%) of clot formation after deployment (1 with a permanent neurologic deficit), 1 case of perioperative stent displacement with hemorrhage, and 5 cases (6.6%) of transient neurologic deficit due to thromboembolic events. The morbidity-mortality rate at discharge was 2.9%. One patient presented with a delayed in-stent thrombosis, and 3 others, with silent stenosis. Twenty-four aneurysms (31.6%) were completely occluded in the initial embolization. However, a marked increase in the occlusion rate was observed, with 44 of the 68 aneurysms (64.7%) examined at the 18-month follow-up and 26 of the 46 aneurysms (56.5%) examined in the 3-year follow-up presenting with complete occlusion. At the end of the study, a neck remnant was present in 6 aneurysms (13%) and a residual sac, in 7 (15.2%). Mean follow-up time was 25.7 months. CONCLUSIONS The present series demonstrates the relative safety and feasibility of the Neuroform stent-assisted coiling technique, which seems to provide better results over coiling alone for wide-neck aneurysms. Angiographic results improve with time due to progressive thrombosis of the aneurysm.

Abstract
BACKGROUND AND PURPOSE The objective of this study is to estimate the number of dementia cases expected to occur in France and Europe over the next few decades until 2050. METHODS Our estimates are based on a model using the European incidence data for dementia by age and sex, the relative mortality risks related to dementia stratified by age classes, and the projections of mortality coefficients in the French and European general population. RESULTS In France, in 2010, the number of dementia cases should reach 754000, i.e., 1.2% of the general population or 2.8% of the active population. By 2050 this number should be multiplied by 2.4, i.e., 1813000 cases, which will be 2.6% of the total population and 6.2% of the active population. In Europe this number could reach more than 6 millions in 2010 and 14 millions in 2050. The sensitivity analysis performed on French data showed that our projections were robust to the use of alternative data for incidence and relative mortality risk (variation of 5.5% and 6.5%), but very sensitive to hypotheses of evolution of mortality (variation of -22% to 29%). CONCLUSIONS The approach used in our study, integrating both the dementia incidence and the mortality in the calculations, allowed us to refine the projections and stress the great sensitivity of the demographic hypotheses forecasts on the evolution of life expectancy. The likely increase is particularly important and confirms that French and European health systems must take this into account when making future plans.

Abstract
BACKGROUND AND METHODS The aim of this study was to assess the effect of lactational exposure to dioxins in neonates on the cytochrome P450 1A1 (CYP1A1) induction in the level of gene expression. Maternal rats were treated with a single dose of 50 or 100 micromol/kg 1,2,3,4-tetrachlorodibenzo-p-dioxin (1,2,3,4-TCDD), a low potent congener of dioxins, on the first day post-partum (day 1). Induction of CYP1A1 mRNA expression was quantitatively analyzed by the competitive reverse transcription-polymerase chain reaction (RT-PCR) method. RESULTS The CYP1A1 mRNA was detectable at extremely low amounts in the liver of control neonates and mothers. The mRNA ratios of CYP1A1 to beta-actin in neonates were dose-dependently increased by the treatment of 1,2,3,4-TCDD of their mothers. Its peak occurred on day 6 and was sustained at the same level on day 10. Increases of the ratio with 100 micromol/kg 1,2,3,4-TCDD on day 2, 6 and 10 were 26-, 40- and 40-fold of the appropriate controls, respectively. These levels paralleled the activity of ethoxyresorufin-o-deethylase, representing CYP1A mediated monooxygenase. In the mother, the mRNA ratio was increased only to threefold of the control, 10 days after treatment. CONCLUSION Current RT-PCR procedure enabled to assess both constitutive and induced levels of CYP1A1 mRNA in the neonatal rat livers. Although the dose of 1,2,3,4-TCDD selected in this study was about 5000 times higher than the daily intake of dioxins in breast-fed infants, CYP1A1 mRNA was highly induced for a longer period of time in neonatal rats receiving 1,2,3,4-TCDD via lactation than the treated maternal rats.

Abstract
A phase II pilot study was carried out on 30 patients to ascertain the toxicity and efficacy of combination chemotherapy with mitoxantrone, methotrexate, 5-fluorouracil (NMF) in the adjuvant setting for axillary lymph node-positive breast cancer. The NMF regimen was mitoxantrone 10 mg/m2, methotrexate 40 mg/m2, and 5-fluorouracil 600 mg/m2 administered i.v. on day 1, repeated every 3-4 weeks for 6 cycles. The median nadir WBC count was 2,000/microl; grade 4 leukocytopenia occurred only in 1 patient. Nausea and vomiting appeared as grade 0 and 1 severity in 26/30 patients. Alopecia was extremely mild, appeared as grade 0 and 1 in 29/30 patients. The overall and relapse-free survival rates were 67.8% and 68.4% at the 82-month follow-up, respectively. The overall survival rate in premenopausal patients was significantly better than that in postmenopausal patients (P<0.05). NMF is a well-tolerated combination regimen, suitable as adjuvant chemotherapy for node-positive breast cancer.

Abstract
Hepatocyte nuclear factor-3 (HNF-3) isoforms are key factors for regulation of gene expression and differentiation in hepatocytes. HNF-3gamma is abundantly expressed in the mature liver, but down-regulated in primary cultured hepatocytes, in which some other hepatic gene expressions are also decreased. In this study, the primary hepatocytes were infected with the recombinant adenovirus carrying HNF-3gamma gene (AxCAHNF3gamma), and this led to marked induction of the HNF-3gamma gene. As a result, the expressions of albumin, catalase, and ornithine transcarbamylase (OTC) genes were also recovered to significant levels in the AxCAHNF3gamma-infected hepatocytes. Moreover, hepatocyte proliferation stimulated by epidermal growth factor (EGF) and insulin was also inhibited by AxCAHNF3gamma infection. Our results demonstrate that the enforced expression of HNF-3gamma gene can lead to conservation of some original liver functions in the primary cultured hepatocytes accompanied by morphological differentiation and growth inhibition.

Abstract
PyNPase activity, MMPs activity and serum IAP values were measured in tumor tissues from colorectal cancer patients who had been divided into two groups, one given preoperative 5'-DFUR and the controls. PyNPase activity of the preoperative administration group was approximately equivalent to that of the controls. In the control group, correlations were assessed between PyNPase activity and activities of MMP1 and MMP3. To assess the effect of 5'-DFUR on the activity of MMPs, we divided patients into two groups, a high and a low PyNPase activity group. Although there was no correlation with MMPs activity of the preoperative administration group and the control group in the low PyNPase activity group, the activities of MMP1 and MMP9 of the control group were significantly higher in the high PyNPase activity group. Moreover, the serum IAP value of the administration group was significantly lower than that of the control group. These results indicated that PyNPase activity was thus suggested to be somehow related to MMPs activity and serum IAP values.

Abstract
Cu, Zn superoxide dismutase (SOD) levels in the serum, cerebrospinal fluid (CSF) and skin fibroblasts of patients with dementia of the Alzheimer type (DAT) were estimated using enzyme immunoassay. The SOD mRNA level in the skin fibroblasts was also determined by the Northern blot analysis. As compared with the age-matched control groups of neurological patients without dementia, the AD group consisting of patients with DAT at ages under 65 years of age as well as the SDAT group of patients with DAT at ages over 65 years of age showed no significant changes in serum or CSF SOD levels. However, the skin fibroblast SOD- and SOD mRNA levels, which were correlate each other, were significantly higher in the AD group (p < 0.05), while lower in the SDAT group (p < 0.05). These results suggest that the determination of the SOD level of skin fibroblast may be useful for diagnosis of DAT and that the abnormality of SOD may play an important role in developing DAT.

Abstract
The effect of human neonatal serum on DNA synthesis in suckling and adult rat hepatocytes in primary culture was investigated to characterize growth regulating factors of the liver in neonates and to confirm whether the stimulatory factor is human hepatocyte growth factor (hHGF). Neonatal serum stimulated DNA synthesis of both adult and suckling rat hepatocytes. The stimulatory effect was dose-dependent up to 20% in volume. The molecular weight of the stimulatory substance in neonatal serum was between 12,500 and 25,000, as estimated by gel filtration. Its activity was stable after heating at 56 degrees C for 20 min, but was lost after heating at 90 degrees C for 30 s, and easily passed through S- or heparin-Sepharose columns. The concentration of hHGF quantified by ELISA was too low to stimulate DNA synthesis in vitro. Biological and biochemical properties of the growth stimulatory activity in neonatal serum differed from that of hHGF. The presence of other growth factors in human neonatal serum for suckling and adult hepatocytes was suggested.

Abstract
We studied the effect of lactoferrin on DNA synthesis in neonatal rat hepatocytes in primary culture to determine if this agent acts as a mitogen in human milk. Thymidine incorporation into the DNA of cultured hepatocytes stimulated by lactoferrin in the presence of insulin and human epidermal growth factor was examined. Iron-saturated lactoferrin increased DNA synthesis of neonatal hepatocytes by 1.5 times and this potency was the same as that of insulin. It significantly enhanced the stimulatory effect of human epidermal growth factor plus insulin; DNA synthesis under these conditions was seven times that of control. Iron-free lactoferrin did not affect DNA synthesis, nor did the exogenous addition of ferric ions. The enhancement of DNA synthesis by iron-saturated lactoferrin was significant for neonatal hepatocytes, but not for adult hepatocytes. These results suggest that iron-saturated lactoferrin, which itself had low mitogenic activity, is a co-mitogenic substance for neonatal hepatocytes in vitro.

Abstract
Superoxide dismutase (SOD) activities in Parkinson's disease (PD) were significantly lower than those in controls, especially in a treated PD group. However, SOD activities in an untreated PD group did not decrease. There was a significant correlation between SOD activities and the duration of illness in the treated PD group (p < 0.05). There was a significant correlation between SOD activities and the present doses of L-DOPA/carbidopa in the treated PD group.

Abstract
An advanced gastric cancer with liver metastasis was treated with the combination MMC, Etoposide and UFT. Etoposide was administered orally at 25-50 mg/day to the gastric cancer patient with liver metastasis. In operative findings, there was no liver and lymphoid node metastasis. The gastric tumor diminished in size and changed its characteristics due to the chemotherapy. In 19 months, no liver nor LN metastasis was observed by CT scan. Presently, the patient feels well and receives outpatient treatment.
