Abstract
Abstract
Background
Recent studies have demonstrated the importance of high-density lipoprotein (HDL) functionality in the development of de novo coronary artery disease by using the cholesterol-efflux capacity, a measure of the ability of HDL to promote cholesterol removal from lipid-laden macrophages. Recently, we developed a rapid cell-free assay system to directly evaluate the capacity of HDL to accept additional cholesterol; the measurement of the cholesterol-uptake capacity (CUC) enables HDL functionality to be readily evaluated in our daily practice. However, prognostic implication of CUC measurement at the timing of percutaneous coronary intervention (PCI) remains unclear.
Purpose
We aimed to evaluate the association between baseline CUC and revascularization during follow-up in the patients who underwent PCI.
Methods
We retrospectively reviewed the patients who underwent PCI with follow-up coronary angiography (CAG) or ischemic-driven revascularization. The patients who had the frozen blood samples of which CUC were measurable at the index PCI and follow-up CAG or revascularization were enrolled. We excluded the patients under hemodialysis.
Results
Among a total of 703 consecutive patients who underwent PCI between Dec 2014 and Mar 2019, we finally enrolled 74 patients who underwent ischemic-driven revascularization (revascularization group) and 183 patients who underwent follow-up CAG without revascularization (non-revascularization group).There were no significant difference in baseline traditional cardiovascular risk factors between the groups. However, the presence of diabetes was significantly more frequent in the revascularization group (63.5% vs 41.0%; P=0.001) than in the non-revascularization group. CUC at the index PCI was significantly lower in the revascularization group than in the non-revascularization group (87.0±19.5 vs 93.9±19.2; P=0.004). Multivariate logistic regression analysis revealed that impaired HDL functionality assessed by decreased CUC level at the index PCI (odds ratio; 0.984, 95% confidence interval; 0.969–1.000) was independently associated with subsequent revascularization after PCI. Indeed, there was a graded inverse association between increasing tertiles of CUC levels and the incidence of revascularization during a median follow-up of 881 days (Figure). Especially in the subgroup analysis of non-diabetic patients, decreased CUC level at the index PCI was independently associated with subsequent revascularization (odds ratio; 0.947, 95% confidence interval; 0.915–0.981), while not in diabetic population.
Conclusion
Serum CUC level at the index procedure was associated with subsequent revascularization especially in non-diabetic patients who underwent PCI.

Abstract
We investigate the near-surface relaxation of freestanding atactic polystyrene films with molecular dynamics simulations. As in previous coarse-grained simulations, relaxation times for backbone segments and phenyl rings are linked to their bulk relaxation times via a power-law coupling relation. Variation of the coupling exponent with distance from the surface is consistent with depth-dependent activation barriers. We also quantify a reduction in dynamical heterogeneity at the interface, which can be interpreted in the framework of cooperative models for glassy dynamics.

Abstract
Abstract
Background
Calcified nodule (CN) in coronary artery is known to be a significant factor for stent underexpansion, however, its baseline characteristics and long-term prognosis is unclear.
Method
421 consecutive severe calcified lesions (Defined as maximum calcium arc >180 degrees) which underwent optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) were analyzed between January 2013 and December 2017. We investigated baseline characteristics and OCT parameter (maximum arc of calcium, maximum thickness of calcium, and length of calcium) and long-term clinical outcome (Major adverse cardiac event (MACE), any cause of death, acute myocardial infarction (AMI) and target vessel failure (TVF)). Median follow up period was 33.7 months.
Result
CN was seen in 22.3% (94 lesions) of all severe calcified lesions. Baseline characteristics and OCT parameters were significantly different in CN and non-CN groups (Hemodialysis; 23.6% vs. 14.1%, p=0.03, Multivessel Disease; 57.4% vs. 44.6, p=0.03, maximum arc of calcium; 305.4 vs. 286.1, p=0.02, maximum thickness of calcium (μm); 1206.2 vs 1123.8, p=0.01, length of calcium (mm); 24.6 vs. 19.0, p=0.01). CN lesions was strongly associated poor long-term clinical outcome (MACE; 50.5% vs. 25.7%, p<0.01), any cause of death; 18.1% vs. 9.5%, p=0.02, AMI; 7.4% vs. 2.4%, p=0.02, TVF; 38.3% vs. 19.2%, p<0.01).
Conclusion
Hemodialysis, multivessel disease and abundant calcium component may have accompanied with CN which may result in poor long-term prognosis.

Abstract
Abstract
Background
Recent reports show that stenting for coronary calcified nodule (CN) resulted in frequent in-stent restenosis, however, its predictors are unclear.
Method
117 consecutive calcified nodule lesions which underwent optical coherence tomography (OCT)-guided PCI were analyzed between January 2013 and March 2018. We investigated baseline characteristics and OCT parameter in CN site (Arc of CN, Lumen area and Symmetry index before and after PCI).
Result
CN site in-stent restenosis was seen 35 lesions (29.9%). Baseline characteristics was significantly different between restenosis group and non-restenosis group (Age; 68.9y.o vs. 73.3y.o, p=0.01, diabetes mellitus; 80.0% vs. 57.3%, Chronic Kidney Disease (CKD); 74.3% vs. 36.6%, Hemodialysis; 54.3% vs. 12.2%). Arc of CN before PCI in restenosis group was larger than that in non-restenosis group (122.7 vs. 110.0 degrees, p=0.01). Post stent symmetry index in restenosis group was smaller than that in non-restenosis group (0.64 vs. 0.75, p<0.01).
Conclusion
Younger patients, diabetes mellitus, CKD, hemodialysis, arc of CN before PCI, post stent symmetry index may be predictors of CN site restenosis.

Abstract
We report measurements of the diffusion rate of isolated ion-implanted ^{8}Li^{+} within ∼120 nm of the surface of oriented single-crystal rutile TiO_{2} using a radiotracer technique. The α particles from the ^{8}Li decay provide a sensitive monitor of the distance from the surface and how the depth profile of ^{8}Li evolves with time. The main findings are that the implanted Li^{+} diffuses and traps at the (001) surface. The T dependence of the diffusivity is described by a bi-Arrhenius expression with activation energies of 0.3341(21) eV above 200 K, whereas at lower temperatures it has a much smaller barrier of 0.0313(15) eV. We consider possible origins for the surface trapping, as well the nature of the low-T barrier.

Abstract
BACKGROUND AND STUDY AIMS Although new image-enhanced endoscopy (IEE) technologies such as blue laser imaging (BLI), BLI-bright, and linked color imaging (LCI) have been developed, their utility for the detection of sessile serrated adenoma/polyps (SSA/Ps) is still unclear. This study aimed to evaluate the utility of BLI, BLI-bright, and LCI for SSA/P detection in still image examinations and in a prospective randomized controlled trial (RCT). PATIENTS AND METHODS A group of 6 expert and non-expert endoscopists read 200 endoscopic still images containing SSA/P lesions using white light image (WLI), BLI, BLI-bright, and LCI. Color differences were calculated using the color space method. A prospective RCT of tandem colonoscopy with WLI and LCI was performed. Patients with SSA/P and those with a history of SSA/P that had been endoscopically removed were enrolled and randomly allocated to WLI-LCI or LCI-WLI groups. Additional endoscopic detection rates for SSA/P were compared between the 2 groups. RESULTS LCI showed the highest SSA/P detection rate among the 4 modes for both expert and non-expert endoscopists. The detection rate with LCI for the 6 expert endoscopists (mean 98.3 ± standard deviation 2.0 %) was significantly higher than that with WLI (86.7 ± 6.0 %, P < 0.01). Likewise, the detection rate with LCI for the 6 non-expert endoscopists (92.3 ± 2.9 %) was significantly higher than that with WLI (72.7 ± 11.5 %, P < 0.01). The color difference of SSA/P with LCI was the highest among the 4 modes, and was significantly higher than with WLI (median 15.9, (interquartile range 13.7 - 20.6) vs. 10.2, (7.6 - 14.2); P < 0.0001). In the RCT, a total of 44 patients (WLI-LCI 22 vs. LCI-WLI 22) underwent colonoscopy. The additional detection rate for SSA/P in the second inspection in the WLI-LCI group (21.6 %, 8/37) was significantly higher than in the LCI-WLI group (3.2 %, 1/31; P = 0.02). The small, flat, non-mucus and isochromatic SSA/Ps in the transverse colon were detected more frequently in the second inspection with LCI. CONCLUSIONS LCI was the most sensitive mode for SSA/P detection among WLI, BLI, BLI-bright, and LCI in the still image examinations. Our RCT strongly suggests that LCI is superior to conventional WLI for SSA/P detection during colonoscopy. UMIN000017599.

Abstract
BACKGROUND/AIMS Gastric xanthomas are frequently observed in the stomach as small yellowish plaques or nodules. A close relationship among Helicobacter pylori infection, atrophic gastritis, and xanthomas has been reported. We assessed the clinicopathological features of gastric cancer with or without xanthomas. METHODS A total of 91 patients who were diagnosed as having early gastric cancer were enrolled. We evaluated the gastritis status using scores for gastritis and atrophy, positivity of H. pylori infection, the prevalence rate of xanthomas, and the clinicopathological features of gastric cancer. RESULTS Gastric xanthomas were observed in 72.5% of early gastric cancer cases. Scores for gastritis and atrophy were significantly higher in the xanthoma-positive group than those in the xanthoma-negative group. A higher prevalence of differentiated-type adenocarcinoma was found in the xanthoma-positive group. Among the cases with multiple gastric xanthomas, the prevalence of males was significantly higher than that of females. CONCLUSION A high prevalence rate of gastric xanthomas in gastric cancer cases was shown. Xanthomas were highly associated with age, the severities of gastritis and atrophy, and differentiated-type adenocarcinoma. Regardless of the eradication of H. pylori, xanthomas may be useful predictive markers for the development of differentiated-type adenocarcinoma.

Abstract
BACKGROUND AND AIM Endoscopic submucosal dissection (ESD), which provides a higher en bloc resection rate than conventional endoscopic mucosal resection (EMR), is considered to be a useful treatment option for large colorectal tumors. However, colorectal ESD is not widely used because of its technical difficulty, risk of complications and time required. To overcome these drawbacks, a simpler modified technique, ESD with snaring (hybrid ESD), has been developed. The aim of the present study was to retrospectively compare the safety and efficacy of hybrid ESD and conventional ESD for colorectal tumors. METHODS Between September 2008 and June 2016, ESD was carried out on 137 lesions and hybrid ESD on 27 lesions. All hybrid ESD cases were carried out as a rescue treatment in difficult ESD cases. We retrospectively investigated procedure time, and the rates of en bloc resection, perforation, bleeding, and local recurrence. RESULTS In the hybrid ESD group, procedure time was shorter compared with the ESD group (108 ± 59.5 min vs 122 ± 72.2 min), but the en bloc resection rate was lower (66.7% vs 94.2%). However, there were no significant differences in procedure time, or in rates of en bloc resection, perforation and bleeding between the two groups. Local recurrence did not develop in any of our cases. CONCLUSIONS Hybrid ESD as a rescue treatment in difficult ESD cases may be less effective for en bloc resection of large colorectal tumors. Indication for hybrid ESD may be limited to scheduled treatment from the outset and emergency cases with patients who present unstable vital signs during ESD.

Abstract
BACKGROUND To prevent tumor metastasis, we administered the cell-binding domain of fibronectin, in combination with the angiogenesis inhibitor TNP-470, to mice with hepatic metastasis. We then assessed the prevention of tumor metastasis resulting from the inhibition of adhesive interactions and the inhibition of angiogenesis. METHODS A hepatic metastasis model was created by injecting 1 x 10(3) colon 26/TC-1 cells into the anterior mesenteric vein of CDF1 mice. The cell-binding domain obtained from fibronectin included the Arg-Gly-Asp (RGD) sequence. A fibronectin-binding domain (FND)-treated group, an FND plus TNP-470 group, and a control group were established. The animals were killed 4 weeks after the injections of the treatment agents had been completed and the number of metastatic liver nodules was counted. In a simultaneous experiment with the same design, the mice were not killed at 4 weeks, and their survival was observed. RESULTS The mean number of nodules in the FND plus TNP-470 group was significantly lower than that in the control group (P = 0.019337). The inhibition rate was 51% in the FND group, 60% in the FND 10 micrograms plus TNP-470 10 mg/kg group, and 64% in the FND 10 micrograms plus TNP-470 100 mg/kg group compared with the control group. Mice from the FND group that were not killed died after 6-8 weeks, but mice from the FND plus TNP-470 group died after 8-12 weeks. CONCLUSION The cell-binding domain of fibronectin may, potentially, be an effective form of antiadhesive therapy that competes with native adhesion molecules and blocks adhesion during the metastatic process. When the cell-binding domain of fibronectin is combined with TNP-470 to inhibit angiogenesis, more effective inhibition of metastatic tumor growth and prolongation of survival can be achieved than after treatment with the cell-binding domain alone.

Abstract
A new advanced glycation end product (AGE), N(omega)-carboxymethyl-arginine (CMA), was found in acid-soluble skin collagen of a newborn bovine prepared by in vitro glycation with 1 M glucose incubation at 37 degrees C for about 30 days [ 1 ]. CMA production was increased with incubation time in parallel, and after 30 days incubation the yield was 100 times higher than that of pentosidine [ 1 ]. This result suggested the importance of CMA as a major AGE in collagen. We have detected and measured the CMA level in human serum proteins by electrospray ionization/liquid chromatography/mass spectrometry (ESI/LC/MS), using CMA standard concentration curve. In this report, we first show the existence of CMA in vivo, and its serum level is significantly elevated in diabetic serum proteins, compared to age-matched control serum proteins. These results provide strong evidence that CMA is a new diagnostic marker of glycation in diabetes.

The prevalence of undertreated, moderate to severe pain is a public health problem in many countries, including the United States. In many cases, opioids should be the mainstay for the treatment of this level of pain, but they often are not used or are underdosed. One of the reasons for this underuse most cited by health care professionals is their fear of sanctions by their governing boards, law enforcement, or their misunderstanding of the laws and regulations governing the use of these controlled substances. This article reviews some of the relevant issues of the regulation of controlled substances, updates the reader about the laws, and provides guidance to practitioners about the appropriate use of controlled substances, especially opioids, to manage pain.

Abstract
While investigating the effect of marine products on cell growth, we found that visceral extracts of Chub mackerel, an ocean fish, had a powerful and dose-dependent apoptosis-inducing effect on a variety of mammalian tumor cells. This activity was strikingly dependent on infection of the C. mackerel with the larval nematode, Anisakis simplex. After purification of the protein responsible for the apoptosis-inducing activity, we cloned the corresponding gene and found it to be a flavoprotein. This protein, termed apoptosis-inducing protein (AIP), was also found to possess an endoplasmic reticulum retention signal (C-terminal KDEL sequence) and H2O2-producing activity, indicating that we had isolated a novel reticuloplasimin with potent apoptosis-inducing activity. AIP was induced in fish only after infection with larval nematode and was localized to capsules that formed around larvae to prevent their migration to host tissues. Our results suggest that AIP may function to impede nematode infection.

Abstract
OBJECTIVE Many residents in long-term care facilities experience nonmalignant pain, and analgesic therapy is often inadequate in this setting. We examined the management of chronic nonmalignant pain in elderly nursing home residents. DESIGN Retrospective chart review. SETTING Forty skilled nursing facilities in southern California. PARTICIPANTS Residents with a diagnosis of noncancer pain who were receiving a regular regimen of prescribed analgesics. MEASUREMENTS The following information was recorded: demographic data, specific diagnosis for pain medication, all analgesics in current use by the resident, whether a pain rating score was available for the resident and, if so, the current score. RESULTS Of the 3400 resident charts screened, 381 residents (11.2%) met the criteria for inclusion in the study. There were 443 diagnoses for chronic nonmalignant pain, primarily arthritis and other musculoskeletal disorders. Of 510 prescriptions for analgesics, 52% were for acetaminophen or nonsteroidal antiinflammatory medications. Centrally acting analgesics, primarily opioids, accounted for 48% of all prescriptions. Approximately three-fourths of opioid prescriptions were for fixed-dose combinations with acetaminophen, and 15% were for long-acting opioids. Pain scores were not recorded on any of the residents' charts. CONCLUSION Nonmalignant pain in these elderly nursing home residents was often associated with musculoskeletal disorders and was not assessed systematically. Without routine pain assessments, it is not possible to determine whether the residents' pain was being treated adequately by the analgesics prescribed. We recommend a multidisciplinary approach to the institution of pain assessment and management guidelines in long-term care facilities.

Abstract
Collagen undergoes continuous non-enzymatic glycation during its long life period. The products resulting from the glycation reaction, so-called advanced glycation end products (AGEs), were regarded as potential pathogens of various diseases such as diabetic complications. Although several AGEs were identified from acid hydrolysates of glycated collagen, the major AGE(s) responsible for the diseases have not yet been fully characterized. Moreover, acid-labile constituents were decomposed during acid hydrolysis. To investigate these AGEs, we used the enzymatic hydrolysis method [Bensusan, Dixit and McKnight (1971) Biochim. Biophys. Acta 251, 100-108]. As a result, an acid-labile unknown compound was discovered from the digested glycated collagen. We identified this compound as N(omega)-carboxymethylarginine (CMA) by matrix-assisted laster-desorption ionization-MS and NMR. CMA gradually increased in collagen during incubation with glucose and the yield reached about 8 mol/mol of collagen, which is 100 times higher than that of pentosidine. This result suggests that CMA is a major AGE in collagen.

Abstract
NB-3 is a neural recognition molecule which is a member of contactin/F3 subgroup in the immunoglobulin superfamily. We report here the developmental expression pattern and localization of NB-3 mRNA in mouse brain, determination of the NB-3 gene organization and identification of the promoter region. We also describe a splicing isoform of mouse NB-3. Mouse NB-3 exhibited 96% identity with rat NB-3 at the amino acid sequence level. The splicing isoform lacked the amino acid residues between 62 and 78 of the original NB-3, which constituted a part of the first immunoglobulin-like domain. The expression of NB-3 mRNA was evident after birth, reaching a maximum at the postnatal seventh day, and declined thereafter in the cerebrum, whereas the mRNA increased in the cerebellum to adulthood. In situ hybridization demonstrated that NB-3 mRNA was preferentially expressed in the accessory olfactory bulb, layers II/III and V of the cerebral cortex, piriform cortex, anterior thalamic nuclei, locus coeruleus of the pons and mesencephalic trigeminal nucleus, and in Purkinje cells of the cerebellum. The mouse NB-3 gene consisted of 23 exons spanning more than 130kb. The overall organization of the gene was similar to those of the F11, axonin-1 and TAX-1 genes of the subgroup. By reporter gene analysis with the 5'-flanking region of the gene, we found a basal promoter activity in the 1.2kb fragment upstream of the putative transcription initiation site. This study provides a basis for elucidating the biological significance of the contactin/F3 subgroup molecules.

Abstract
A novel ficolin-related gene was isolated from the mouse liver lambda ZAPII cDNA library. The protein encoded by this gene consists of both collagen- and fibrinogen-like domains, which are common features of the ficolin family, and was named mouse ficolin-A. The amino acid sequence of mouse ficolin-A is 60.2, 59.8, 59.8, and 59.6% identical to those of porcine ficolin-alpha, -beta, human ficolin-1, and EBP-37/P35, respectively. Northern blot analysis showed that mRNA of mouse ficolin-A is highly expressed in liver and spleen. Immunoblot analysis using an anti-mouse ficolin-A antiserum showed that mouse ficolin-A is a plasma protein with binding activity to elastin and GlcNAc.

Abstract
The third multicopy suppressor gene of the PDI1 deletion from Saccharomyces cerevisiae, MPD2, was isolated and characterized. The MPD2 gene encodes a protein with a putative signal sequence, ER retention signal, and a disulfide isomerase active site like sequence. The amino acid sequence around the active site like sequence is similar to the thioredoxin-like domains of PDI and PDI related proteins, although the similarity is comparatively low. A delta-pdi1 strain over-producing Mpd2p showed slow growth and was sensitive to 1 mM dithiothreitol. Mpd2p can be detected in wild type cells and is a glycoprotein. Although the MPD2 gene was not essential for growth, overexpression of the gene partially restored the maturation defect of carboxypeptidase Y caused by the PDI1 deletion. Mutagenesis analysis revealed that Mpd2p can compensate for the loss of PDI with its CXXC sequence.
