Abstract
The Japanese mitten crab Eriocheir japonica inhabits rivers throughout Japan and is being cultivated for food. To conduct aquaculture efficiently, it is crucial to comprehend the physiological functions of the target organisms. However, there is a lack of fundamental information on Japanese mitten crabs. In this study, hydrolases were extracted from the midgut glands of Japanese mitten crabs and their metabolic activities were analyzed. An enzyme with hydrolytic activity was discovered within the cytosol of the midgut gland. Western blot analysis also revealed that the Japanese mitten crab contains a hydrolase with cross-reactivity to human carboxylesterase 1 (hCES1) antibodies. The substrate specificity of the S9 fraction of the midgut gland was investigated and, interestingly, it was revealed that it reacts well with indomethacin phenyl ester and fluorescein diacetate, which are substrates of hCES2, not substrates of hCES1. Furthermore, this enzyme was observed to metabolize the ester derivative of astaxanthin, which is a red pigment inherent to the Japanese mitten crab. These findings underscore the significance the midgut gland in the Japanese mitten crab as an important organ for metabolizing both endogenous and exogenous ester-type compounds.

Abstract
1. Carboxylesterase (CES) has been studied extensively, mostly with substrates in the monoester structures. We investigated the relationship between indomethacin diester prodrugs and metabolic activation by microsomes and recombinant human CES.2. Eight indomethacin diester prodrugs were synthesised in two steps. They were used as substrates and hydrolysis rates were calculated.3. As a result, the major hydrolysis enzyme was CES. The hydrolysis rate of recombinant CES2A1 was comparable to that of recombinant CES1A1.4. In this study, by changing the structure of the prodrug to a diester structure, it was found that CES2 activity was equivalent to CES1 activity.5. It should be noted that the use of diester prodrugs in prodrug discovery, where organ-specific hydrolysis reactions are expected, may not yield the expected results.

Abstract
PURPOSE/OBJECTIVE(S) In oligo metastases in lymph node recurrence after surgery for esophageal cancer, since SBRT (BED>100 Gy10) to mediastinal and abdominal lymph node lesions was not an option due to toxicities in the organs at risk (OAR) such as vessels and gastrointestinal tract, we performed a prospective cohort study of hypofractionated IGRT for isolated lesions. The primary end-points of this study are disease specific survival (DSS) and late treatment toxicities. MATERIALS/METHODS From 2011 to 2021, 60 Gy/20F/4-4.5wks (78 Gy10) hypofractionated IGRT was performed in a total ITT population of 70 patients after radical surgery (67 cases) and ESD (3 cases), who were diagnosed by CT/PET-CT as having solitary lymph node recurrence (62 cases) or up to 2 adjacent nodes (8 cases). The mean time from surgery to recurrence was 17.9 months (SD 18.1) with a mean age of 67.5 years (SD 9.3), and male to female ratio was 62:8. Pathological results showed that 63 patients (90%) had squamous cell carcinoma. The mean maximum diameter of lesions was 2.5 cm (SD; 1.1 cm). And 51 cases (73%) were treated with CRT concurrently using 5FU plus CDDP (FP), and the rest were treated with RT alone. Lymph node location was lower neck or upper mediastinum in 42 cases, middle and lower mediastinum in 16 cases, and abdomen in 12 cases, respectively. Treatment planning was performed by taking 4DCT fusing PET or MRI images. The Kaplan-Meier method and the Cox proportional hazards regression model were used for overall survival (OS), DSS, and progression free survival (PFS). RESULTS The mean observation period was 38 months. Primary efficacy was CR in 45 cases (64%), but CR was maintained only in 29 cases (41%). Twenty-two of the 70 patients were relapse-free. OS were 53% and 34% at 2 and 5 years, DSS were 56% and 38% at 2 and 5 years, and PFS were 40% and 39% at 2 and 5 years, respectively. The site of first recurrence was the same or adjacent lymph nodes in 33 cases (47%) and distant metastases in 9 cases (13%). Number of tumors (1 vs. 2), age, and CRT were not significant prognostic factors for OS, DSS, or PFS. In a multivariate analysis, the time from surgery to recurrence ≥12 months was the only significant prognostic factor for PFS (p = 0.018, HR0.50). The same multivariate analysis showed that the only significant prognostic factor for DSS was the location of the recurrent lymph node in the neck and upper mediastinal regions (p = 0.009, HR 0.59). The only late adverse events of Grade 2 or higher were Grade 2 pleural effusion (little and transient) in 6 cases and Grade 2 radiation pneumonitis in 1 case. No acute adverse events were observed other than hematologic toxicity due to FP administration. CONCLUSION In locally advanced esophageal cancer, a relatively reliable regional lymph node dissection is often performed, so there is still a chance to aim for cure in cases of solitary recurrence. We found that if the lesion is solitary, localized RT of about 60 Gy/20F/4-4.5 weeks with IGRT can achieve a long-term survival in 40% of patients without any significant adverse events.

Abstract
Carboxylesterase (CES) plays an important role in the hydrolysis metabolism of ester-type drugs and prodrugs. In this study, we investigated the change in the hydrolysis rate of hCE1 by focusing on the steric hindrance of the ester structure and the electron density. For 26 kinds of synthesized indomethacin prodrugs, the hydrolytic rate was measured in the presence of human liver microsomes (HLM), human small intestine microsomes (HIM), hCE1 and hCE2. The synthesized prodrugs were classified into three types: an alkyl ester type that is specifically metabolized by hCE1, a phenyl ester type that is more easily metabolized by hCE1 than by hCE2, and a carbonate ester type that is easily metabolized by both hCE1 and hCE2. The hydrolytic rate of 1-methylpentyl (hexan-2-yl) ester was 10-times lower than that of 4-methylpentyl ester in hCE1 solution. hCE2 was susceptible to electron density of the substrate, and there was a difference in the hydrolysis rate of up to 3.5-times between p-bromophenyl ester and p-acetylphenyl ester. By changing the steric hindrance and electron density of the alkoxy group, the factors that change the hydrolysis rate by CES were elucidated.

Abstract
Insoluble aggregated proteins are often associated with neurodegenerative diseases. Previously, we investigated chemical chaperones that prevent the aggregation of denatured proteins. Among these, 4-phenyl butyric acid (4-PBA) has well-documented chemical chaperone activity, but is required at doses that have multiple effects on cells, warranting further optimization of treatment regimens. In this study, we demonstrate chemical chaperone activities of the novel compound indole-3-propionic acid (IPA). Although it has already been reported that IPA prevents β-amyloid aggregation, herein we show that this compound suppresses aggregation of denatured proteins. Our experiments with a cell culture model of Parkinson's disease are the first to show that IPA prevents endoplasmic reticulum (ER) stress and thereby protects against neuronal cell death. We suggest that IPA has potential for the treatment of neurodegenerative diseases and other diseases for which ER stress has been implicated.

Abstract
Two types of haloperidol prodrugs in which a chemical modification was carried out on the hydroxyl group or carbonyl group were synthesized, and their metabolic activation abilities were evaluated in a human liver microsome (HLM) solution, a human small intestine microsome (HIM) solution and solutions of human recombinant carboxylesterases (hCESs). The metabolic activation rates of alcohol ester prodrugs in HLM solution were similar to those in hCES2 solution, and haloperidol pentanoate and haloperidol hexanoate showed high metabolic activation rates in the synthesized alcohol ester prodrugs. In addition, haloperidol acetate and haloperidol 2-methylbutanoate were hydrolyzed as slowly as haloperidol decanoate. The results suggested that haloperidol prodrugs with a small chain or a branched chain are useful as prodrugs for sustained release. The metabolic activation rate of the enol ester prodrug in HLM solution was similar to that in hCES1 solution, and the enol ester prodrug was found to behave differently from alcohol ester prodrugs, which were metabolically activated by hCES2.

Abstract
The protocooperation between Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus relies on metabolite exchanges that accelerate acidification during yogurt fermentation. Conflicting results have been obtained in terms of the effect of the Strep. thermophilus urease and the NH3 and CO2 that it generates on the rate of acidification in yogurt fermentation. It is difficult to perform a systematic study of the effects of urease on protocooperation because it is necessary to distinguish among the direct, indirect, and strain-specific effects resulting from the combination of the strains of both species. To evaluate the direct effects of urease on protocooperation, we generated 3 urease-deficient mutants (ΔureC) of fast- and slow-acidifying Strep. thermophilus strains and observed the effects of NH3 or CO2 supplementation on acidification by the ΔureC strains. Further, we examined 5 combinations of 3 urease-deficient ΔureC strains with 2 CO2-responsive or CO2-unresponsive strains of L. bulgaricus. Urease deficiency induced a shortage of ammonia nitrogen and CO2 for the fast- and slow-acidifying Strep. thermophilus and for the CO2-responsive L. bulgaricus, respectively. Notably, the shortage of ammonia nitrogen had more severe effects than that of CO2 on yogurt fermentation, even if coculture with L. bulgaricus masked the effect of urease deficiency. Our work established (1) that urease deficiency inhibits the fermentative acceleration of protocooperation regardless of the Strep. thermophilus and L. bulgaricus strain combinations, and (2) that urease is an essential factor for effective yogurt acidification.

Abstract
We discovered that a reagent comprising a combination of PhBCl2 and nitriles was useful for syntheses of both 3-acylindoles and 1-(1H-indol-3-yl)alkylamine from indoles. The reaction proceeded selectively at the 3-position of indoles providing 3-acylindoles in moderate to high yields on treatment with the above reagent. Furthermore, the reaction provided the corresponding amine products in moderate to high yields after the intermediate imine was reduced by NaBH3CN. These reactions proceeded under mild conditions and are applicable to the formation of indoles functionalized at the 3-position.

Abstract
Background Neuropsychiatric side effects of oseltamivir occur occasionally, especially in infants and young patients, but nothing is known about possible contributory factors. Case presentation We report a case of a 15-year-old Japanese female with influenza infection who developed abnormal psychiatric symptoms after administration of standard doses of oseltamivir. She had no history of neurological illness, had never previously taken oseltamivir, and had not developed psychiatric reactions during previous influenza infection. Her delirium-like symptoms, including insomnia, visual hallucinations, and a long-term memory deficit, disappeared after cessation of oseltamivir and administration of benzodiazepine. Detailed assessment was performed, including neurological examination (electroencephalogram, brain magnetic resonance imaging, single photon emission computed tomography with 99mTc-ethyl cysteinate dimer and with 123I-iomazenil, cerebrospinal fluid analysis and glutamate receptor autoantibodies), drug level determination and simulation, and genetic assessment (OAT1, OAT3, CES1, Neu2). Conclusions Abnormal slowing in the electroencephalogram, which is characteristic of influenza-associated encephalopathy, was not observed in repeated recordings. The serum level determination of active metabolite Ro 64-0802 determined at 154 h after final dosing of oseltamivir was higher than the expected value, suggesting delayed elimination of Ro 64-0802. Thus, abnormal exposure to Ro 64-0802 might have contributed, at least in part, to the development of neuropsychiatric symptoms in this patient. The score on Naranjo’s adverse drug reaction probability scale was 6. Mutation of c.122G > A (R41Q) in the sialidase Neu2 gene, increased CSF glutamate receptor autoantibodies, and limbic GABAergic dysfunction indicated by SPECT with 123I-iomazenil were found as possible contributory factors to the CNS side effects.

Abstract
Arylacetamide deacetylase (AADAC), a microsomal serine esterase, hydrolyzes drugs, such as flutamide, phenacetin and rifampicin. Because AADAC has not been fully investigated at molecular levels in cynomolgus macaques, the non-human primate species widely used in drug metabolism studies, cynomolgus AADAC cDNA was isolated and characterized. The deduced amino acid sequence, highly homologous (92%) to human AADAC, was more closely clustered with human AADAC than the dog, rat or mouse ortholog in a phylogenetic tree. AADAC was flanked by AADACL2 and SUCNR1 in the cynomolgus and human genomes. Moreover, relatively abundant expression of AADAC mRNA was found in liver and jejunum, the drug-metabolizing organs, in cynomolgus macaques, similar to humans. The results suggest molecular similarities of AADAC between cynomolgus macaques and humans.

Abstract
AIMS Multiple system atrophy (MSA) is pathologically characterized by the formation of α-synuclein-containing glial cytoplasmic inclusions (GCIs) in oligodendrocytes. However, the mechanisms of GCI formation are not fully understood. Cellular machinery for the formation of aggresomes has been linked to the biogenesis of the Lewy body, a characteristic α-synuclein-containing inclusion of Parkinson's disease and dementia with Lewy bodies. Here, we examined whether GCIs contain the components of aggresomes by immunohistochemistry. METHODS Sections from five patients with MSA were stained immunohistochemically with antibodies against aggresome-related proteins and analysed in comparison with sections from five patients with no neurological disease. We evaluated the presence or absence of aggresome-related proteins in GCIs by double immunofluorescence and immunoelectron microscopy. RESULTS GCIs were clearly immunolabelled with antibodies against aggresome-related proteins, such as γ-tubulin, histone deacetylase 6 (HDAC6) and 20S proteasome subunits. Neuronal cytoplasmic inclusions (NCIs) were also immunopositive for these aggresome-related proteins. Double immunofluorescence staining and quantitative analysis demonstrated that the majority of GCIs contained these proteins, as well as other aggresome-related proteins, such as Hsp70, Hsp90 and 62-kDa protein/sequestosome 1 (p62/SQSTM1). Immunoelectron microscopy demonstrated immunoreactivities for γ-tubulin and HDAC6 along the fibrils comprising GCIs. CONCLUSIONS Our results indicate that GCIs, and probably NCIs, share at least some characteristics with aggresomes in terms of their protein components. Therefore, GCIs and NCIs may be another manifestation of aggresome-related inclusion bodies observed in neurodegenerative diseases.

Abstract
BACKGROUNDS AND PURPOSE Lactic acidosis is a fatal adverse effect of metformin, but the risk factor remains unclear. Multidrug and toxin extrusion 1 (MATE1) is expressed in the luminal membrane of the kidney and liver. MATE1 was revealed to be responsible for the tubular and biliary secretion of metformin. Therefore, some MATE polymorphisms, that cause it to function abnormally, are hypothesized to induce lactic acidosis. The purpose of this study is to clarify the association between MATE dysfunction and metformin-induced lactic acidosis. EXPERIMENTAL APPROACH Blood lactate, pH and bicarbonate ion (HCO(3) (-) ) levels were evaluated during continuous administration of 3 mg·mL(-1) metformin in drinking water using Mate1 knockout (-/-), heterozygous (+/-) and wild-type (+/+) mice. To determine the tissue accumulation of metformin, mice were given 400 mg·kg(-1) metformin orally. Furthermore, blood lactate data were obtained from diabetic patients given metformin. KEY RESULTS Seven days after metformin administration in drinking water, significantly higher blood lactate, lower pH and HCO(3) (-) levels were observed in Mate1(-/-) mice, but not in Mate1(+/-) mice. The blood lactate levels were not affected in patients with the heterozygous MATE variant (MATE1-L125F, MATE1-G64D, MATE2-K-G211V). Sixty minutes after metformin administration (400 mg·kg(-1) , p.o.) the hepatic concentration of metformin was markedly higher in Mate1(-/-) mice than in Mate1(+/+) mice. CONCLUSION AND IMPLICATIONS MATE1 dysfunction caused a marked elevation in the metformin concentration in the liver and led to lactic acidosis, suggesting that the homozygous MATE1 variant could be one of the risk factors for metformin-induced lactic acidosis.

Abstract
Thirty patients who underwent hepatectomy for the treatment of hepatocellular carcinoma (HCC) were examined for expression of HLA class I antigens on HCC cells by flow cytometry. The expression was found significantly lower in cases of stage IV compared with those of stage I or stage II (p<0.05), and in cases of intrahepatic metastases compared with those without metastases (p<0.001). In cases of non-curative hepatectomy, the expression of HLA class I antigens was lower compared with those treated by curative resection. Postoperative cumulative disease-free survival rates were well correlated with the expression rate of HLA class I antigens (p<0.05). Expression of HLA class I antigens on HCC may indicate low malignancy and better prognosis.

Abstract
Prostaglandin (PG) F(2α) is one of the major prostanoids biosynthesized by cyclooxygenases (COXs) from arachidonic acid. Although it has been reported that there is a selective surge in PGF(2α) production in the hippocampus during kainic acid (KA)-induced seizure activity, the precise intra-hippocampal distribution of PGF(2α) has not been elucidated due to the paucity of effective histological techniques for detecting PGs in tissues. We investigated the tissue distribution of PGF(2α) in the rat hippocampus 30 min after KA injection by developing fixation and immunohistological-staining methods. To detect PGF(2α) directly on histological sections, we used systemic perfusion fixation with water-soluble carbodiimide fixative, followed by immersion of the brains in Zamboni's fixative. We then performed immunofluorescence staining with anti-PGF(2α) antibody, with negative control experiments used to confirm the staining specificity. Definitive immunolabeling for PGF(2α) was evident most markedly in pyramidal cells of the hippocampal cornu Ammonis (CA) 3 sector and neurons of the hilus in KA-treated rats. Immunolabeling for PGF(2α) was also evident in granule cells of the dentate gyrus. Double immunfluorescence staining revealed that PGF(2α)-immunopositive neurons expressed cytosolic phospholipases A(2), COX-2, and FP receptor. These results suggest that the major source of PGF(2α) production immediately after KA injection was neurons of the hippocampal CA3 sector, hilus and dentate gyrus. These neurons exert PGF(2α)-mediated functions via FP receptors in an autocrine/paracrine manner and may play pathophysiological roles in the acute phase (30 min) of excitotoxicity.

Abstract
BACKGROUND AND STUDY AIMS Growing evidence suggests that esophageal stricture frequently develops after endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) in early esophageal cancer patients, with an incidence proportional to the greater extent of mucosal defects resulting from improved EMR/ESD techniques. There seems to be a potential risk of perforation during bougienage in such patients. PATIENTS AND METHODS 648 stricture dilations for 78 lesions in 76 patients were consecutively included. The outcomes after combined use of Maloney and Savary wire-guided bougienage for esophageal strictures after EMR/ESD were analyzed in a single-institute retrospective case series study. The perforation rate was determined and risk factors for perforation were identified. RESULTS Patients underwent a median of 5.0 dilation procedures performed over a median 3.0 months for post-EMR/ESD strictures. Initial dilation was done a median 14 days following endoscopic resection. Perforations developed in seven patients (7/648 dilation procedures, 1.1%), all in the lower esophagus, and bleeding occurred in one patient (0.1% dilations). Two independent risk factors for development of perforation during dilation therapy for post-EMR/ESD stricture were identified: multiple dilations (odds ratio [OR] 1.2; P=0.012), and lower site of stricture (OR 12.8; P=0.043). Dysphagia was ameliorated by the dilations, and no patient required surgery. CONCLUSIONS A specific emerging risk of perforation in dilation therapy for post-EMR/ESD strictures was identified. Carefully planned treatment is necessary in patients with severe post-EMR/ESD strictures especially strictures requiring multiple dilations or located in the lower esophagus.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Association of UDP-glucuronosyltransferase 1A1 (UGT1A1) genetic polymorphisms *6 and *28 with reduced clearance of SN-38 and severe neutropenia in irinotecan therapy was demonstrated in Japanese cancer patients. * The detailed gene structure of CES1 has been characterized. * Possible functional SNPs in the promoter region have been reported. WHAT THIS STUDY ADDS * Association of functional CES1 gene number with AUC ratio [(SN-38 + SN-38G)/irinotecan], an in vivo index of CES activity, was observed in patients with irinotecan monotherapy. * No significant effects of major CES1 SNPs on irinotecan PK were detected. AIMS Human carboxylesterase 1 (CES1) hydrolyzes irinotecan to produce an active metabolite SN-38 in the liver. The human CES1 gene family consists of two functional genes, CES1A1 (1A1) and CES1A2 (1A2), which are located tail-to-tail on chromosome 16q13-q22.1 (CES1A2-1A1). The pseudogene CES1A3 (1A3) and a chimeric CES1A1 variant (var1A1) are also found as polymorphic isoforms of 1A2 and 1A1, respectively. In this study, roles of CES1 genotypes and major SNPs in irinotecan pharmacokinetics were investigated in Japanese cancer patients. METHODS CES1A diplotypes [combinations of haplotypes A (1A3-1A1), B (1A2-1A1), C (1A3-var1A1) and D (1A2-var1A1)] and the major SNPs (-75T>G and -30G>A in 1A1, and -816A>C in 1A2 and 1A3) were determined in 177 Japanese cancer patients. Associations of CES1 genotypes, number of functional CES1 genes (1A1, 1A2 and var1A1) and major SNPs, with the AUC ratio of (SN-38 + SN-38G)/irinotecan, a parameter of in vivo CES activity, were analyzed for 58 patients treated with irinotecan monotherapy. RESULTS The median AUC ratio of patients having three or four functional CES1 genes (diplotypes A/B, A/D or B/C, C/D, B/B and B/D; n= 35) was 1.24-fold of that in patients with two functional CES1 genes (diplotypes A/A, A/C and C/C; n= 23) [median (25th-75th percentiles): 0.31 (0.25-0.38) vs. 0.25 (0.20-0.32), P= 0.0134]. No significant effects of var1A1 and the major SNPs examined were observed. CONCLUSION This study suggests a gene-dose effect of functional CES1A genes on SN-38 formation in irinotecan-treated Japanese cancer patients.

Abstract
Mammalian carboxylesterase (CES or Ces) genes encode enzymes that participate in xenobiotic, drug, and lipid metabolism in the body and are members of at least five gene families. Tandem duplications have added more genes for some families, particularly for mouse and rat genomes, which has caused confusion in naming rodent Ces genes. This article describes a new nomenclature system for human, mouse, and rat carboxylesterase genes that identifies homolog gene families and allocates a unique name for each gene. The guidelines of human, mouse, and rat gene nomenclature committees were followed and "CES" (human) and "Ces" (mouse and rat) root symbols were used followed by the family number (e.g., human CES1). Where multiple genes were identified for a family or where a clash occurred with an existing gene name, a letter was added (e.g., human CES4A; mouse and rat Ces1a) that reflected gene relatedness among rodent species (e.g., mouse and rat Ces1a). Pseudogenes were named by adding "P" and a number to the human gene name (e.g., human CES1P1) or by using a new letter followed by ps for mouse and rat Ces pseudogenes (e.g., Ces2d-ps). Gene transcript isoforms were named by adding the GenBank accession ID to the gene symbol (e.g., human CES1_AB119995 or mouse Ces1e_BC019208). This nomenclature improves our understanding of human, mouse, and rat CES/Ces gene families and facilitates research into the structure, function, and evolution of these gene families. It also serves as a model for naming CES genes from other mammalian species.
