Abstract
Background Familial lecithin: cholesterol acyltransferase (LCAT) deficiency (FLD) is a severe inherited disease without effective treatment. Patients with FLD develop severe low HDL, corneal opacity, hemolytic anemia, and renal injury. Objective We developed genetically modified adipocytes (GMAC) secreting LCAT (LCAT-GMAC) for ex vivo gene therapy. GMACs were prepared from the patient’s adipocytes to express LCAT by retroviral gene transduction to secrete functional enzymes. This study aimed to evaluate the safety and efficacy of LCAT-GMAC implantation in an FLD patient. Methods Proliferative preadipocytes were obtained from a patient using a ceiling culture and retrovirally transduced with LCAT. After obtaining enough cells by expansion culture of the transduced cells, the resulting LCAT-GMACs were implanted into a patient with FLD. To evaluate the safety and efficacy, we analyzed the outcome of the autologous implantation for 24 weeks of observation and subsequent 240 weeks of the follow-up periods. Results This first-in-human autologous implantation of LCAT-GMACs was shown to be safe by evaluating adverse events. The LCAT-GMAC implantation increased serum LCAT activity by approximately 50% of the baseline and sustained over three years. Consistent with increased LCAT activity, intermediate-density lipoprotein (IDL) and free cholesterol levels of the small and very small HDL fractions decreased. We found the hemoglobin/haptoglobin complex in the hemolyzed pre-implantation sera of the patient. After one week of the implantation, the hemoglobin/haptoglobin complex almost disappeared. Immediately after the implantation, the patient's proteinuria decreased temporarily to mild levels and gradually increased to the baseline. At 48 weeks after implantation, the patient's proteinuria deteriorated with the development of mild hypertension. By the treatment with antihypertensives, the patient's blood pressure normalized. With the normalization of blood pressure, the proteinuria rapidly decreased to mild proteinuria levels. Conclusions LCAT-GMAC implantation in a patient with FLD is shown to be safe and appears to be effective, in part, for treating anemia and proteinuria in FLD.

Abstract
BackgroundThe management of rheumatoid arthritis (RA) has been transformed by the use of molecular targeted therapies. Early treatment and treat-to-target approach leads to good clinical response and remission (responders), but not in all patients.Environmental factors including diet contribute to the development, activity and severity of RA. Evidence from clinical trials suggested that dietary interventions, such as Mediterranean diet or supplementation with fish oil rich in n-3 polyunsaturated fatty acids (n-3 PUFA), have positive effects on RA. Japanese and Mediterranean diets are associated with longevity and characterized by high fish intake. Clinical studies have identified predictors of treatment response in individual RA patients, however, the influence of fish consumption on treatment response in RA patients treated with targeted therapies has not been elucidated.ObjectivesTo assess whether fish consumption is associated with a good response to targeted therapies in RA patients with Japanese and Mediterranean dietary patterns.MethodsThe study is a collaborative international cross-sectional retrospective study enrolling patients with RA on treatment with biologics or JAK inhibitors attending to Hokkaido University Hospital, Japan or Hospital Virgen de las Nieves, Spain.Enrolled patients were asked to complete a brief-type self-administered diet history questionnaire (BDHQ) and a detailed fish frequency questionnaire (DFFQ) referring to consumption frequency in the previous month. At study entry, alcohol consumption, tobacco habits, educational level and employment status were recorded and RA disease activity evaluated by qualified rheumatologists. Demographic, clinical/laboratory data were retrospectively extracted from the medical records.By December 2021, 279 patients (Japan 217, Spain 62) returned the questionnaires. A preliminary analysis was carried out with the first 58 Japanese patients in which all clinical and laboratory data could be collected. A descriptive analysis was performed and the relative risks approximated by odds ratios.ResultsFifty-eight Japanese RA patients, 45 females, median age at entry 66 yrs [IQR 54-73], median disease duration 11yrs [IQR 7-20] were included in this analysis. Fifty-three (93%) of patients were on biologic therapies and four (7%) on JAK inhibitors with a median treatment duration of 4.5 yrs [IQR 1-7]. Concomitant treatment with conventional DMARDS and glucocorticoids were reported in 69% and 48% of patients, respectively. Forty-two (72%) patients were responders to treatment defined as DASESR ≦3.2. Another systemic autoimmune disease, hypertension, diabetes mellitus, dyslipidemia or gout history were present in 29%, 29%, 9%, 33% and 10% of patients, respectively.All patients had consumption of fish in the last month and an intake of n3-PUFA rich fish (fatty fish) was indicated by 82% (<1 time/week 34%, ≧ 1 time/week 48%).The patients’ fatty and non-fatty fish intake scores were calculated with a mathematical formula based on the intake of each of the fish included in the DFFQ and number of responses. In the group of high fatty fish score patients (≧ 1 time/week) 94% were responders to treatment vs. 6% non-responders, [OR 8.75, CI [1.0-73.54, p= 0.022] while only 63% of patients in the high non-fatty fish score group respond to the treatment.ConclusionFatty fish intake associated with a good response to treatment in patients receiving targeted therapies, suggesting that fish consumption may have some beneficial effects on RA treatment.ReferencesThere is no reference.AcknowledgementsAcknowledgements to Ms. Y.

Abstract
Salmonella Enteritidis has developed the potential to contaminate eggs by surviving in the antimicrobial environment of the hen's egg white. This has led to a worldwide pandemic of foodborne salmonellosis infections in humans due to the consumption of contaminated eggs and egg-derived products. The molecular mechanisms of Salmonella Enteritidis egg white survival are not fully clear. Using in vivo expression technology and promoter-reporter fusions we showed that the promoter of the tolC gene, encoding the TolC outer membrane channel that is used by multidrug efflux pumps to export harmful molecules and to secrete bacterial products, is activated by egg white at the chicken body temperature. Using a Salmonella Enteritidis tolC deletion mutant we showed that TolC has an important role in egg white survival. Chromatographic separation techniques and subsequent testing of antimicrobial activities of separated egg white fractions led to the identification of ovotransferrin as the egg white antimicrobial factor which is capable of inhibiting growth of a tolC deletion strain but not the wild type strain. We provide evidence that TolC protects Salmonella Enteritidis against ovotransferrin-mediated growth inhibition in egg white.

Abstract
Styrenic copolymers comprising styrene, methyl methacrylate, and maleic anhydride were developed to improve the heat-resistance property of poly(methyl methacrylate) (PMMA). The optical, thermal, and mechanical properties were examined for the blend specimens prepared by an injection-molding machine using melt-mixed samples. It was found that the copolymers, which were miscible with PMMA, increase the glass transition temperature and therefore the Vicat Softening temperature. Furthermore, the blends were completely transparent as similar to PMMA.

Abstract
BACKGROUND Gefitinib treatment results in considerably better progression-free survival compared with that of platinum doublets in the first line treatment of nonsmall-cell lung cancer (NSCLC) carrying an activating epidermal growth factor receptor (EGFR) mutation. Some patients who respond to gefitinib have an overall survival (OS) of more than 5 years, whereas other initial responders do less well. Although there has been considerable effort made to elucidate the mechanisms of acquired resistance, there have only been a few studies that addressed the effect of clinical backgrounds and treatment histories on the survival of the patients who had responded to an EGFR-tyrosine kinase inhibitor (TKI). In this study, we especially focused on the clinical benefit of EGFR-TKI administration after progression. PATIENTS AND METHODS We retrospectively analyzed consecutive patients with advanced NSCLC who were diagnosed before October 2010, treated with gefitinib after July 2002, and responded to it. The primary objective of this study was to evaluate how clinical backgrounds and treatment histories influence survival of the patients who respond to gefitinib. The secondary objectives were to evaluate the safety of long-term gefitinib use and to establish the optimal treatment sequence using a dynamic treatment regimen analysis (DTRA). RESULTS A total of 335 patients were recruited. Twenty-eight (8.4%) patients survived more than 5 years. Sixty-five and 93 patients received gefitinib as rechallenge and beyond progressive disease (BPD), respectively. A statistically significant difference in OS was observed between the patients who underwent gefitinib rechallenge and those who did not rechallenge (median: 1272 days vs. 774 days; p < 0.001), a result supported by a DTRA. Patients treated with gefitinib BPD also showed a tendency of longer survival. CONCLUSIONS Gefitinib rechallenge and BPD played a central role in long term survival of the patients who initially responded to gefitinib.

Abstract
BACKGROUND AND PURPOSE If blood flow in the ICA is reduced by the use of a distal filter during CAS, flow stagnation proximal to the filter occurs and this increases the probability of floating debris. The floating debris that remains after filter retrieval may cause cerebral embolism. However, if blood flow is increased by aspiration of blood from the ICA through an aspiration catheter, debris could be removed while the filter is still in place. The purpose of this study was to investigate blood flow changes in the ICA induced by filter use and aspiration. MATERIAL AND METHODS A filter-protection device (AngioGuard XP) was used during CAS in 13 consecutive patients with carotid stenosis. Blood flow velocity in the ICA was measured by carotid Doppler sonography during filter deployment, filter retrieval, and catheter aspiration. RESULTS Blood flow velocity significantly decreased with filter placement and significantly increased with filter retrieval in patients with normal angiographic flow (P < .05). Aspiration of a 20-mL blood sample from the proximal ICA column significantly increased the blood flow velocity (P < .05). CONCLUSIONS The blood flow changes in the ICA induced by the use of a distal filter may cause cerebral embolism in filter-protected CAS. A routine aspiration method can potentially reduce the amount of migrating debris during CAS, even in cases with angiographic normal flow.

Abstract
Replication checkpoint protein Rad17 senses DNA lesions during DNA replication and halts progression of replication fork. The cells derived from Bloom syndrome individuals show some defects in DNA replication. In order to investigate the functional relationship between the replication checkpoint protein Rad17 and BLM, which is the product of the causative gene of Bloom syndrome, we generated BLM/RAD17 double knockout (blm/rad17) cells using chicken DT40 cells. The blm/rad17 cells showed exaggerated growth defects as determined by analysis of their growth curves and plating efficiency compared to those of either of the single gene mutants. These defects seem to be due to an increase in DNA lesions that cause spontaneous cell death, suggesting that Rad17 and BLM execute different functions in the progression of replication forks. We also demonstrate that targeting integration was dramatically compromised by a lack of Rad17. In addition, the elevated frequency of sister chromatid exchange (SCE) due to homologous recombination in BLM knockout (blm) cells was greatly reduced by disruption of the RAD17 gene. Thus, in addition to its role in the replication checkpoint, Rad17 appears to play a role in homologous recombination.

Abstract
BACKGROUND Placement of detachable coil(s) for intracranial aneurysms has become one of the standard methods of management. Although detailed analysis of post-procedure changes in aneurysmal lumen is essential, technical difficulties often limit such evaluation. Development of higher magnetic field systems is steadily widening clinical usage of magnetic resonance imaging (MRI) primarily due to its significantly higher signal to noise ratio. OBJECTIVE In this study, we evaluated a multi-planar reconstruction (MPR) technique of magnetic resonance angiography (MRA) on a 3.0T system in an attempt to develop a routine method of post-procedure evaluation following detachable coil placement. METHODS Eleven patients with an intracranial aneurysm following placement of a Guglielmi detachable coil (GDC) participated in the study. Time of flight (TOF) magnetic resonance angiography (MRA) was obtained immediately after, and up to two years after coil embolisation utilising a GE 3.0T system. Data was analysed using standard maximum intensity projection (MIP) as well as the MPR technique and the results were compared to conventional catheter angiography. RESULTS The study demonstrated that, compared to MIP, MPR can provide further information of alteration in aneurysm lumen, especially in analysis of: 1) jet of blood flow, 2) thrombus formation, 3) neck remnant or re-filling of blood, 4) location and shape of coils including compaction, and 5) coil protrusion into the parent artery. CONCLUSIONS Combined MPR/MIP analysis of high-field MRA appears to be a powerful non-invasive method for evaluating GDC-treatment that can potentially replace conventional catheter angiography in many clinical situations.

Abstract
BACKGROUND AND PURPOSE The development of flat panel detectors (FPDs) has made cone-beam CT feasible for practical use in a clinical setting. Our purpose was to assess the usefulness of cone-beam CT using the FPD in conjunction with conventional digital subtraction angiography (DSA) for performing superselective intra-arterial chemotherapy for head and neck tumors. MATERIALS AND METHODS Twenty-three consecutive patients (43 feeding arteries) were prospectively examined. All of the patients underwent intra-arterial rotational angiography using an FPD system, and the cone-beam CT was reconstructed from the volume dataset. Two radiologists evaluated the quality of the cone-beam CT and then evaluated whether the additional information provided by the cone-beam CT was useful for the interventional procedures. RESULTS In 41 (95%) of 43 arteries, the extent of contrast material perfusion was sufficiently visualized on cone-beam CT. In 20 (47%) of 43 arteries, the DSA plus cone-beam CT was superior to the DSA alone regarding the precise understanding of vascular territory of each artery. This information was helpful for predicting the drug delivery for superselective intra-arterial chemotherapy, especially in deeply invasive tumors with multiple feeding arteries. CONCLUSION In superselective intra-arterial chemotherapy for head and neck tumors, cone-beam CT with FPD provides useful additional information, which allows interventional radiologists to determine the feeders, as well as the dose of antitumor agent for each feeder.

Abstract
BACKGROUND AND PURPOSE Compared with the image intensifier (I.I.)-TV system, the flat panel detector (FPD) system of direct conversion type has several theoretic advantages, such as higher spatial resolution, wide dynamic range, and no image distortion. The purpose of this study was to compare the image quality of 3D digital subtraction angiography (DSA) in the FPD and conventional I.I.-TV systems using a vascular phantom. MATERIALS AND METHODS An anthropomorphic vascular phantom was designed to simulate the various intracranial aneurysms with aneurysmal bleb. The tubes of this vascular phantom were filled with 2 concentrations of contrast material (300 and 150 mg I/mL), and we obtained 3D DSA using the FPD and I.I.-TV systems. First, 2 blinded radiologists compared the volume-rendering images for 3D DSA on the FPD and I.I.-TV systems, looking for pseudostenosis artifacts. Then, 2 other radiologists independently evaluated both systems for the depiction of the simulated aneurysm and aneurysmal bleb using a 5-point scale. RESULTS For the degree of the pseudostenosis artifacts at the M1 segment of the middle cerebral artery at 300 mg I/mL, 3D DSA with FPD system showed mild stenoses, whereas severe stenoses were observed at 3D DSA with I.I.-TV system. At both concentrations, the FPD system was significantly superior to I.I.-TV system regarding the depiction of aneurysm and aneurysmal bleb. CONCLUSION Compared with the I.I.-TV system, the FPD system could create high-resolution 3D DSA combined with a reduction of the pseudostenosis artifacts.

Abstract
BACKGROUND AND PURPOSE Compared with image intensifier television (I.I.-TV) system, an angiography system using the flat panel detector (FPD) of direct conversion type has a high spatial resolution, which may improve image quality, reduce patient exposure, or both. Our purpose was to evaluate the detection of simulated aneurysmal blebs under dose reduction with the FPD system in comparison with the I.I.-TV system. MATERIALS AND METHODS A vascular phantom was designed to simulate various intracranial aneurysms with and without blebs, and this phantom was filled with 3 different concentrations of contrast material (300, 150, and 100 mg I/mL). 2D digital subtraction angiography (DSA) at low-dose mode of FPD system was compared with 2D DSA at a standard-dose mode of FPD system and a conventional mode of I.I.-TV system. Data analysis was based on 171 observations (57 aneurysms [20 with bleb and 37 without bleb] x 3 contrast material concentrations) by each of 7 radiologists, and the detection performances of blebs were compared using a receiver operating characteristic (ROC) analysis. RESULTS The mean dose measurements with a phantom during 2D DSA were 0.36 mGy/frame with low-dose mode of FPD system, 0.72 mGy/frame with standard-dose mode of FPD system and 0.76 mGy/frame with I.I.-TV system. The mean Az at 100 mg I/mL was significantly higher for low-dose mode of FPD than for conventional-dose mode of I.I.-TV mean Az, 0.85 versus 0.56; P < .01), though differences were not significant with 150 and 300 mg I/mL between both systems. CONCLUSION The FPD system allows a considerable dose reduction during 2D DSA without loss of the image quality.

Abstract
A-63-year-old woman underwent gamma knife surgery (GKS) for acoustic neuroma. Six years later, she suffered sudden onset of severe headache followed by a disturbance of consciousness and subarachnoid haemorrhage due to a ruptured aneurysm originating from the distal anterior inferior cerebellar artery. The aneurysm was not located at a branching site and was included within the radiation field. The aneurysm was treated by endovascular embolization, and now, 15 months later, the patient has recovered satisfactorily. This is the first report of aneurysm formation following GKS for acoustic neuroma.

Abstract
Werner was originally identified as a protein that interacts with the product of the Werner syndrome (WS) gene, WRN. To examine the function of the WRNIP1/WRN complex in cells, we generated knock-out cell lines that were deficient in either WRN (WRN(-/-)), WRNIP1 (WRNIP10(-/-/-)), or both (WRNIP1(-/-/-)/WRN(-/-)), using a chicken B lymphocyte cell line, DT40. WRNIP1(-/-/-)/WRN(-/-) DT40 cells grew at a similar rate as wild-type cells, but the rate of spontaneous sister-chromatid exchange was augmented compared to that of either of the single mutant cell lines. Moreover, while WRNIP1(-/-/-) and WRN(-/-) cells were moderately sensitive to camptothecin (CPT), double mutant cells showed a synergistic increase in CPT sensitivity. This suggested that WRNIP1 and WRN do not always function cooperatively to repair DNA lesions. The lack of a discernable functional interaction between WRNIP1 and WRN prompted us to reevaluate the nature of the physical interaction between these proteins. We found that MBP-tagged WRNIP1 interacted directly with WRN, and that the interaction was enhanced by the addition of ATP. Mutations in the Walker A motifs of the two proteins revealed that WRNIP1, but not WRN, must bind ATP before an efficient interaction can occur.

Abstract
In Saccharomyces cerevisiae, Rad18 functions in post-replication repair pathways, such as error-free damage bypass involving Rad30 (Poleta) and error-prone damage bypass involving Rev3/7 (Polzeta). Chicken DT40 RAD18(-/-) cells were found to be hypersensitive to camptothecin (CPT), while RAD30(-/-) and REV3(-/-) cells, which are defective in translesion DNA synthesis, were not. RAD18(-/-) cells also showed higher levels of H2AX phosphorylation and chromosomal aberrations, particularly chromosomal gaps and breaks, upon exposure to CPT. Detailed analysis by alkaline sucrose density gradient centrifugation revealed that RAD18(-/-) and wild type cells exhibited similar rates of elongation of newly synthesized DNA in the presence or absence of low concentrations of CPT but that DNA breaks frequently occurred on both parental and nascent strands within 1h after a brief exposure to an elevated concentration of CPT, with more breaks induced in RAD18(-/-) cells than in wild type cells. These data suggest a previously unanticipated role for Rad18 in dealing with replication forks upon encountering DNA lesions induced by CPT.

Abstract
PURPOSE To investigate whether inflammatory responses are more severe in uveitic eyes than nonuveitic eyes when acrylic intraocular lens (IOL) is implanted after cataract surgery. METHODS Clear lens removal (phacoemulsification and aspiration) was conducted and the hydrophobic acrylic IOL (AR40e, AMO) was implanted in adult albino rabbits. Just after the operation, rabbits were divided into two groups. One group (nine rabbits) received intravitreal injection of lipopolysaccharide (LPS, 200 ng/10 microl) into both eyes to induce endotoxin-induced uveitis (EIU) and the other group (nine rabbits) received intravitreal injection of phosphate-buffered saline (PBS, 10 microl) into both eyes as the control. Aqueous humour (AH) and IOLs were harvested 1, 3 , and 7 days after the intravitreal injection. The infiltrating cell number in AH was counted and the protein concentration of AH was measured. IOLs were evaluated morphologically. RESULTS At 1 day after intravitreal injection, both the infiltrating cell number in AH and protein concentration of AH were significantly higher in the LPS-injected group than in the PBS-injected group. Similarly, more inflammatory cells attached to the surfaces of the IOLs in the LPS-injected group. However, 7 days later, inflammatory reactions subsided and no clear differences in any of the parameters examined were observed between the two groups. CONCLUSIONS At 7 days after the operation, inflammatory reactions in eyes implanted with the hydrophobic acrylic IOLs were similar in uveitic eyes and nonuveitic eyes. The data suggest that the hydrophobic acrylic IOLs may be suitable for patients with uveitis.

Abstract
Several techniques have been developed for recovering reflectance properties of real surfaces under unknown illumination. However, in most cases, those techniques assume that the light sources are located at inifinity, which cannot be applied safely to, for example, reflectance modeling of indoor environments. In this paper, we propose two types of methods to estimate the surface reflectance property of an object, as well as the position of a light source from a single view without the distant illumination assumption, thus relaxing the conditions in the previous methods. Given a real image and a 3D geometric model of an object with specular reflection as inputs, the first method estimates the light source position by fitting to the Lambertian diffuse component, while separating the specular and diffuse components by using an iterative relaxation scheme. Our second method extends that first method by using as input a specular component image, which is acquired by analyzing multiple polarization images taken from a single view, thus removing its constraints on the diffuse reflectance property. This method simultaneously recovers the reflectance properties and the light source positions by optimizing the linearity of a log-transformed Torrance-Sparrow model. By estimating the object's reflectance property and the light source position, we can freely generate synthetic images of the target object under arbitrary lighting conditions with not only source direction modification but also source-surface distance modification. Experimental results show the accuracy of our estimation framework.

Abstract
In this paper, we tackle the problem of geometric and photometric modeling of large intricately shaped objects. Typical target objects we consider are cultural heritage objects. When constructing models of such objects, we are faced with several important issues that have not been addressed in the past-issues that mainly arise due to the large amount of data that has to be handled. We propose two novel approaches to efficiently handle such large amounts of data: A highly adaptive algorithm for merging range images and an adaptive nearest-neighbor search to be used with the algorithm. We construct an integrated mesh model of the target object in adaptive resolution, taking into account the geometric and/or photometric attributes associated with the range images. We use surface curvature for the geometric attributes and (laser) reflectance values for the photometric attributes. This adaptive merging framework leads to a significant reduction in the necessary amount of computational resources. Furthermore, the resulting adaptive mesh models can be of great use for applications such as texture mapping, as we will briefly demonstrate. Additionally, we propose an additional test for the k-d tree nearest-neighbor search algorithm. Our approach successfully omits back-tracking, which is controlled adaptively depending on the distance to the nearest neighbor. Since the main consumption of computational cost lies in the nearest-neighbor search, the proposed algorithm leads to a significant speed-up of the whole merging process. In this paper, we present the theories and algorithms of our approaches with pseudo code and apply them to several real objects, including large-scale cultural assets.

Abstract
As an aim toward developing new antiulcer agents, new N-substituted N'-[3-[3-(piperidinomethyl)phenoxy]propyl]ureas were synthesized and evaluated for histamine H2-receptor antagonistic, gastric antisecretory, and gastric mucosal protective activities. A QSAR study showed that the most favorable N-substituents were electron-donating straight-chain alkyl groups of short length such as ethyl group from the viewpoint of dual action, i.e., gastric antisecretory and mucosal protective actions. Among the ureas studied, compounds 4, 5, and 8-10 were selected as candidates for further study.

Abstract
Recent clinical trials of cancer gene therapy have shown encouraging results for controlling localized tumors. However, to control metastatic or disseminated tumor cells, further modification of vectors is required to enhance specificity and infectivity against targets. We investigated whether utilization of the Cre recombinase(Cre)/loxP system contributes to enhanced antitumor effects together with minimal adverse reactions in specific gene therapy against disseminated carcinoembryonic antigen (CEA)-producing cancer cells in the peritoneal cavity of mice. CEA-producing cancer would be a good therapeutic target because it is found in lung, stomach and colon sites, which account for most cancers. We constructed a pair of recombinant adenoviral vectors (Ads), one of which expresses the Cre gene under the control of the CEA promoter (Ad.CEA-Cre); the other expresses the herpes simplex virus thymidine kinase (HSV-TK) gene (Ad.lox-TK), or the beta-galactosidase gene (beta-gal) by Cre (Ad.lox-beta-gal). Intraperitoneal coinjection of Ad.CEA-Cre and Ad.lox-beta-gal into mice with peritonitis carcinomatosa by CEA-producing tumor cells showed selective expression of the beta-gal gene in tumor foci. Coinfection of Ad.CEA-Cre and Ad.lox-TK followed by ganciclovir (GCV) administration significantly suppressed the total tumor weight in the peritoneal cavity of the mice to 13% of that of the untreated mice and 22% of that of the mice treated with Ad.CEA-TK/GCV, an Ad that expressed the HSV-TK gene driven by the CEA promoter alone. Moreover, treatment with Ad.CEA-Cre and Ad.lox-TK/GCV completely suppressed tumors in 4 of 10 (40%) mice without significant weight loss, although 2 of 10 mice treated with Ad.CAG-TK/GCV, an adenovirus vector that strongly but nonspecifically expressed the TK gene, died due to severe side effects including diarrhea, weight loss and liver dysfunction. These findings suggest that cell type-specific gene therapy using the Cre/loxP system is effective against disseminated cancer cells without significant side effects.

Abstract
L-threo-3, 4-dihydroxyphenylserine (L-DOPS) is a precursor of norepinephrine. We reported that administration of L-DOPS to rats with ablation of the right sensorimotor cortex results in functional recovery from deficits in beam-walking performance. We al so reported that improvement in Fugl-Meyer Score (FMS) was significantly higher in an L-DOPS-treated group of chronic neurologically stable stroke patients than in a control group for 2 days. In the present study, 27 patients who had suffered from stroke more than one month previously and had exhibited no improvement in neurological deficits for at least one week were administered 300mg/day L-DOPS for 28 days with rehabilitation. FMS improved by 4.4 points (P< 0.001), 10m gait time was shortened by 16% (P< 0.001) and the cerebral blood flow of the lesion was increased (P< 0.03), after 28 days of drug administration. These findings suggest that L-DOPS is effective in restoring neurological deficit, which does not usually recover when only treated with rehabilitation therapy.

Abstract
In the Escherichia coli genome, five putative open reading frame (ORF) clusters, mdlAB, ybjYZ, yddA, yojHI, and yhiH, have been assumed to be possible genes for ABC drug efflux transporters (I. T. Paulsen, M. K. Sliwinski, and M. H. Saier, Jr., J. Mol. Biol. 277:573-592, 1998). We cloned all of these ORFs in multicopy plasmids and investigated the drug resistance of drug-supersensitive host cells lacking constitutive multidrug efflux transporter genes acrAB. Among them, only ybjYZ gave significant erythromycin resistance and significantly decreased the accumulation of [(14)C]erythromycin. Therefore, ybjYZ was renamed macAB (macrolide-specific ABC-type efflux carrier). Plasmids carrying both the macA and -B genes conferred resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. Neither of the two genes produced resistance alone. The DNA sequence suggests that MacB is an integral membrane protein with four transmembrane segments and one nucleotide-binding domain, while MacA belongs to a membrane fusion protein (MFP) family with a signal-like sequence at its N terminus. The expression of the histidine-tagged proteins confirmed that MacB is an integral membrane protein and MacA is a peripheral membrane protein. In addition, MacAB required TolC for its function in a way similar to that of most of the MFP-dependent transporters in E. coli. MacB is thus a novel ABC-type macrolide efflux transporter which functions by cooperating with the MFP MacA and the multifunctional outer membrane channel TolC. This is the first case of an experimentally identified ABC antibiotic efflux transporter in gram-negative organisms.
