A slice test system has been constructed for the ATLAS end-cap muon level-I trigger. ATLAS is one of the four Large Hadron Collider (LHC) experiment. Although the system has been constructed using prototype application specific integrated circuits (ASICs) and electronics modules, the design scheme of the trigger, readout as well as control logic applied to the system is the final one. The size is about 1/300 of the whole number of channels. The purpose of the slice test is to demonstrate the system design and performance in detail prior to production commitment. In this paper, we discuss the validity of the logic through the comparison of the simulation results, the latency measurement and long run tests. Index Terms--Application specific integrated circuits (ASICs), data acqusisition, triggering.

Aminopeptidase activity was demonstrated in Mycoplasma salivarium (ATCC 23064) cells disrupted by sonic vibrations and lyophilized (crude enzymes), and weak endopeptidase or carboxypeptidase activity was also suggested. The crude enzymes were suspended in 0.1 M borate buffer, pH 8.0, containing 0.5% (w/v) sodium deoxycholate, and then the suspensions were centrifuged at 100,000 g for 2 h. Thus separated, the supernatants were applied to a column of Sephacryl S-300. As a result, aminopeptidase activity was separated from caseinolytic activity, which had already been demonstrated in this organism. The aminopeptidase activity was inhibited by o-phenanthroline and stimulated by Mn, and the enzyme exhibited a strong affinity for leucine and arginine. On the other hand, the caseinolytic activity was inhibited considerably by o-phenanthroline and Ni and slightly by diisopropyl fluorophosphate and Co. The caseinolytic activity was therefore believed to be due mainly to metalloproteinases and partly to serine proteinases. [ABSTRACT FROM AUTHOR]

Abstract: GABAergic interneurons play central roles in the regulation of neuronal activity in the basolateral nucleus of the amygdala (BLA). They are also suggested to be the principal targets of the brainstem noradrenergic afferents which are involved in the enhancement of the BLA-related memory. In addition, behavioral stress has been shown to impair noradrenergic facilitation of GABAergic transmission. However, the noradrenaline (NA) effects in the BLA have not been differentiated among medium- to large-sized GABAergic neurons and principal cells, and remain to be elucidated in terms of their underlying mechanisms. Glutamate decarboxylase 67 (GAD67) is a biosynthetic enzyme of GABA and is specifically expressed in GABAergic neurons. To facilitate the study of the NA effects on GABAergic neurons in live preparations, we generated GAD67–green fluorescent protein (GFP) knock-in mice, in which GFP was expressed under the control of an endogenous GAD67 gene promoter. Here, we show that GFP was specifically expressed in GABAergic neurons in the BLA of this GAD67–GFP knock-in mouse. Under whole-cell patch-clamp recordings in vitro, we identified a certain subpopulation of GABAergic neurons in the BLA chiefly on the basis of the electrophysiological properties. When depolarized by a current injection, these neurons, which are referred to as type A, generated action potentials at relatively low frequency. We found that NA directly excited type-A cells via α1-adrenoceptors, whereas its effects on the other types of neurons were negligible. Two ionic mechanisms were involved in this excitability: the activation of nonselective cationic conductance and the suppression of the resting K+ conductance. NA also increased the frequency of spontaneous IPSCs in the principal cells of the BLA. It is suggested that the NA-dependent excitation of type-A cells attenuates the BLA output for a certain period. [Copyright &y& Elsevier]

Background and Objectives: Muscle cramps are often observed in patients with liver diseases, especially advanced liver fibrosis. The exact prevalence of muscle cramps in outpatients with liver diseases in Japan is unknown. Patients and Methods: This study examined the prevalence of, and therapies for, muscle cramps in outpatients with liver diseases in Tokyo, Japan. A total of 238 outpatients with liver diseases were retrospectively examined. We investigated whether they had muscle cramps using a visual analog scale (VAS) (from 0, none, to 10, strongest), and also investigated their therapies. Results: Muscle cramps were observed in 34 outpatients with liver diseases (14.3%); their mean VAS score was 5.53. A multivariate analysis demonstrated that older age (equal to or older than 66 years) was the only significant factor as-sociated with muscle cramps. The prevalence of muscle cramps among patients with liver diseases seemed not to be higher. The problem was that only 11 (32.4%) of 34 outpatients received therapy for their muscle cramps. Conclusions: Only age is related to muscle cramps, which is rather weak, and it is possible that this common symptom may not be limited to liver disease patients.

To reduce the immunogenicity of β-lactoglobulin (BLG), we prepared recombinant BLG which has both site-specific glycosylation and single amino acid substitution (D28N/P126A), and expressed it in the methylotrophic yeast Pichia pastoris by fusion of the cDNA to the sequence coding for the α-factor signal peptide from Saccharomyces cerevisiae. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis indicated that the D28N/P126A was conjugated with a ∼4 kDa high-mannose chain. D28N/P126A retained ∼61% of the retinol-binding activity of BLG. Structural analyses by circular dichroism (CD) spectra, intrinsic fluorescence, and Enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies indicated that the surface structure of BLG was slightly changed by using protein engineering techniques, but D28N/P126A was covered by high-mannose chains and substituted amino acid without substantial disruption of native conformation. Antibody responses to the D28N/P126A considerably reduced in C57BL/6 mice. We conclude that inducing both site-specific glycosylation and single amino acid substitution simultaneously is an effective method to reduce the immunogenicity of BLG., (© The Author(s) 2022.

To reduce the immunogenicity of β-lactoglobulin (BLG), we prepared single amino acid substituted recombinant BLG mutants (BLG/P126A, BLG/V128D and BLG/D129A) in the methylotrophic yeast Pichia Pastris by fusion of the cDNA to the sequence coding for the α-factor signal peptide from Saccharomyces cerevisiae . Isoelectric points of single amino acid substituted BLGs were lower than that of native BLG. CD spectra indicated that the secondary structure of BLG had maintained native structure in single amino acid substituted BLGs. Fluorescence studies indicated that the conformation around Trp had not changed in single amino acid substituted BLGs. Anti-BLG antibody response was evaluated after immunization to C57BL/6 mice. Antibody response was reduced after immunization with BLG/P126A, BLG/V128D and BLG/D129A. And novel immunogenicity was not observed in the experiments. T cell proliferative response was evaluated in C57BL/6 mice, and it was clarified that BLG mutants also showed low response. Methods employed in this study was considered to be very effective to reduce immunogenicity of BLG., Competing Interests: Conflict of interestThe authors have no conflicts of interest to declare., (© The Author(s), under exclusive licence to Springer Nature B.V. 2022, Springer Nature or its licensor holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are fatal adverse skin reactions characterized by high fever, epidermal detachment, and mucositis. It is well known that SJS/TEN occasionally affects various organs, leading to permanent damage and death in some patients. Although acute liver dysfunction is a relatively common complication of SJS/TEN, severe acute liver dysfunction requiring liver transplantation is rare. We present the case of a 14-year-old girl with SJS complicated by severe and rapidly progressive liver dysfunction, specifically, acute liver failure (ALF) requiring liver transplantation. A lymphocyte transformation test showed positive results for acetaminophen and cefdinir. Furthermore, human leukocyte antigen (HLA) genotyping revealed the presence of the HLA-A*02:06 genotype, which is reported to be strongly associated with acetaminophen-related SJS/TEN with severe ocular complications. These results suggested that our patient may have presented with acetaminophen-induced SJS complicated by ALF, but no ocular complications. This is the first report of a pediatric patient with SJS who required liver transplantation. In rare instances, severe liver dysfunction requiring liver transplantation should be considered as a possible complication of SJS/TEN., (© 2021 Japanese Dermatological Association.)

Macroautophagy/autophagy plays a critical role in the pathogenesis of various human diseases including neurodegenerative disorders such as Parkinson disease (PD) and Huntington disease (HD). Chemical autophagy inducers are expected to serve as disease-modifying agents by eliminating cytotoxic/damaged proteins. Although many autophagy inducers have been identified, their precise molecular mechanisms are not fully understood because of the complicated crosstalk among signaling pathways. To address this issue, we performed several chemical genomic analyses enabling us to comprehend the dominancy among the autophagy-associated pathways followed by an aggresome-clearance assay. In a first step, more than 400 target-established small molecules were assessed for their ability to activate autophagic flux in neuronal PC12D cells, and we identified 39 compounds as autophagy inducers. We then profiled the autophagy inducers by testing their effect on the induction of autophagy by 200 well-established signal transduction modulators. Our principal component analysis (PCA) and clustering analysis using a dataset of "autophagy profiles" revealed that two Food and Drug Administration (FDA)-approved drugs, memantine and clemastine, activate endoplasmic reticulum (ER) stress responses, which could lead to autophagy induction. We also confirmed that SMK-17, a recently identified autophagy inducer, induced autophagy via the PRKC/PKC-TFEB pathway, as had been predicted from PCA. Finally, we showed that almost all of the autophagy inducers tested in this present work significantly enhanced the clearance of the protein aggregates observed in cellular models of PD and HD. These results, with the combined approach, suggested that autophagy-activating small molecules may improve proteinopathies by eliminating nonfunctional protein aggregates.

A 74-year-old man with a history of transfusion at 35 years old in Egypt was referred to our hospital. He was infected with hepatitis C virus (HCV) genotype 4 (GT4), which is a rare HCV GT in Japan, and was also diagnosed with hepatic compensated cirrhosis. We safely treated the patient for 12 weeks with the combination of glecaprevir and pibrentasvir, and a sustained virologic response (SVR) was achieved. This is the first report of HCV GT4 infection in a treatment-naïve Japanese patient with cirrhosis in whom SVR was achieved with the combination treatment of glecaprevir and pibrentasvir.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening disorders characterized by widespread epidermal necrosis of the skin and mucosa. The severity-of-illness scoring system for TEN (SCORTEN) was widely used since 2000 as a standard prognostic tool consisting of seven clinical values., Methods: To evaluate the prognosis using current treatments and risk factors for mortality, we retrospectively analyzed 59 cases of TEN, including SJS/TEN overlap treated in two university hospitals from January 2000 to March 2020., Results: The mortality rate of TEN was 13.6% (8/59). All patients treated with high-dose steroid administration in combination with plasma exchange and/or immunoglobulin therapy recovered. Logistic regression analysis showed nine clinical composite scores, namely: heart rate (≧120 bpm), malignancy present, percentage of body surface area with epidermal detachment (>10%), blood urea nitrogen (>28 mg/dL), serum bicarbonate level (<20 mEq/L), serum glucose level (>252 mg/dL), age (≧71 years), the interval between disease onset and treatment initiation at the specialty hospital (≧8 days), and respiratory disorder within 48 h after admission. The receiver operating characteristic curves confirmed a high potential for predicting the prognosis of TEN., Conclusions: Recent developments in treatment strategies have contributed to the improved prognosis of TEN patients. A modified severity scoring model composed of nine scores may be helpful in the prediction of TEN prognosis in recent patients. Further large-scale studies are needed to confirm mortality findings to improve prognostication in patients with TEN., (Copyright © 2020 Japanese Society of Allergology.

Pulmonary diseases, including chronic obstructive pulmonary disease (COPD), are major chronic diseases that result in decreased pulmonary function. Relationships between body composition and pulmonary function have been reported. However, few epidemiological studies have used the visceral fat area (VFA) to measure body composition. This study aimed to examine the relationship between body composition and pulmonary function. A cross-sectional study was conducted between 2015 and 2016, using data obtained from 1,287 residents aged between 19 and 91 years living in the Iwaki area of Hirosaki City, a rural region in Aomori Prefecture, Japan. Pulmonary function was evaluated using the forced vital capacity (FVC) as a percentage of the predicted value (predicted FVC%) and the ratio of forced expiratory volume in one second (FEV1) to FVC. The measurements for evaluating body composition included the body fat percentage (BFP) of the whole body and trunk, skeletal muscle index (SMI), body mass index (BMI), VFA, waist circumference (WC) at the navel level, and waist-to-hip ratio (WHR). To adjust for potential confounders, Spearman's partial correlation analysis was used to examine the relationship between the measurements of body composition and pulmonary function. There were significant correlations between the predicted FVC% and the following parameters: BFP (whole body and trunk) in younger males; SMI in older males; WC, VFA, BMI, and SMI in younger females; and BFP (whole body and trunk) and VFA in older females. Contrastingly, WC and VFA in younger males and WC in younger females were correlated with the FEV1/FVC ratio. VFA was correlated with the FEV1/FVC ratio in younger males and predicted FVC% in older females. These findings suggest that visceral fat accumulation may increase the development of obstructive pulmonary disease in young males and accelerate the decline of pulmonary function (predicted FVC%) in older females., Competing Interests: The author Y.K. received funding from Health Care Food Research Laboratories, Kao Corporation, Tokyo, Japan, a commercial company, in the form of salary and research materials.

Pegylated liposomal doxorubicin (PLD) is an anthracycline anticancer agent used in ovarian cancer and a form of doxorubicin enclosed in pegylated liposomes. There are only a few reports on intertrigo-like eruptions caused by PLD. We describe the first case of severe bullous erythema, including intertrigo-like eruptions with angioedema, induced by PLD in Japan. We present the case of a 53-year-old woman who was diagnosed with stage IIIC ovarian cancer. After receiving three cycles of PLD, the patient developed swelling of the upper lip and painful erythema with blisters and erosions on the axilla, upper back, flank and wrists. The patient was diagnosed with angioedema and severe skin lesions, including intertrigo-like eruptions induced by PLD. Although treatment with oral prednisolone and topical steroids was effective against these eruptions, the administration of PLD was discontinued because of its ineffectiveness against the primary disease. Several risk factors, such as obesity, perspiration and racial differences, may contribute toward a severe manifestation such as that seen in our patient. Moreover, our case was the first accompanied by angioedema. The mechanism of coexistence of intertrigo-like eruptions and angioedema is not clear; further studies are required to clarify the pathological mechanism of intertrigo-like eruptions., (© 2019 Japanese Dermatological Association.)

Necroptosis is a regulated form of necrosis that depends on receptor-interacting protein kinase (RIPK)3 and mixed lineage kinase domain-like (MLKL). While danger-associated molecular pattern (DAMP)s are involved in various pathological conditions and released from dead cells, the underlying mechanisms are not fully understood. Here we develop a fluorescence resonance energy transfer (FRET) biosensor, termed SMART (a sensor for MLKL activation by RIPK3 based on FRET). SMART is composed of a fragment of MLKL and monitors necroptosis, but not apoptosis or necrosis. Mechanistically, SMART monitors plasma membrane translocation of oligomerized MLKL, which is induced by RIPK3 or mutational activation. SMART in combination with imaging of the release of nuclear DAMPs and Live-Cell Imaging for Secretion activity (LCI-S) reveals two different modes of the release of High Mobility Group Box 1 from necroptotic cells. Thus, SMART and LCI-S uncover novel regulation of the release of DAMPs during necroptosis.

This paper proposes an olfactory stimulation-biological response measurement system aiming for quantitative and objective evaluation the odor quality. The system calculates arterial stiffness index $\beta $ proposed by our group, the low frequency/high frequency (LF/HF), and heart rate (HR) during presenting odor stimuli. An experiment of olfactory sensory assessment using the proposed system is conducted. The experiment results showed that unpleasant odor increases arterial stiffness index $\beta $ and (LF/HF).

In a previously reported double-blind, randomized controlled trial (RCT), we demonstrated that daily supplementation with anserine (750 mg) and carnosine (250 mg) improves brain blood flow and memory function in elderly people. Here, we conducted a sub-analysis of MRI data and test scores from the same RCT to determine whether anserine/carnosine supplementation specifically benefits elderly people carrying the APOE e4 allele, which is a risk gene for accelerated brain aging and for the onset of Alzheimer's Disease. We collected data from 68 participants aged 65 years or older who received anserine/carnosine supplementation (ACS) or placebo for 12 months. Subjects were assessed at the start and end of the trial using several neuropsychological tests, including the Wechsler Memory Scale-Logical Memory (WMS-LM). We also collected two types of MRI data, arterial spin labeling (ASL) and diffusion tensor imaging (DTI) at the start and end of the trial. We found that ACS significantly preserved verbal memory (WMS-LM, F[1,65] = 4.2003, p = 0.0445) and blood flow at frontal areas of the brain (FWE cluster level , p < 0.001). Sub-analysis based on the APOE4 genotype showed a significant preservation of blood flow ( p = 0.002, by ASL analysis) and white-matter microstructure ( p = 0.003, by DTI analysis) at prefrontal areas in APOE4 + subjects in the active group, while there was no significant difference between APOE4 - subjects in the active and placebo groups. The effect of ACS in preserving brain structure and function in elderly people carrying APOE4 should be verified by further studies., Competing Interests: Conflict of Interest NH Food Ltd., provided the supplements free of charge. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Recent studies have revealed that various food components affect the immune response. These components act on various immune cells, and their effects are mediated through the intestinal immune system and, in some cases, the intestinal microbiota. In this review, we describe the immunomodulating effects of various food components, including probiotics, prebiotics, polysaccharides, vitamins, minerals, fatty acids, peptides, amino acids and polyphenols. Some of these components enhance immune responses, leading to host defense against infection, whereas others inhibit immune responses, thus suppressing allergy and inflammation.

Our goal was to determine whether anserine/carnosine supplementation (ACS) suppresses chemokine levels in elderly people. In a double-blind randomized controlled trial, volunteers were assigned to the ACS or placebo group (1:1). Sixty healthy elderly volunteers (active, n = 30; placebo, n = 30) completed the study. The ACS group was administered 1.0 g of anserine/carnosine (3:1) for 3 months. A microarray analysis and subsequent quantitative real-time polymerase chain reaction (qRT-PCR) analysis of peripheral blood mononuclear cells (PBMCs) showed decreased expression of CCL24, an inflammatory chemokine ( p < 0.05). Verbal memory, assessed using the Wechsler memory scale-logical memory, was preserved in the ACS group. An age-restricted sub-analysis showed significant verbal memory preservation by ACS in participants who were in their 60s (active, n = 12; placebo, n = 9; p = 0.048) and 70s (active, n = 7; placebo, n = 11; p = 0.017). The suppression of CCL24 expression was greatest in people who were in their 70s ( p < 0.01). There was a significant correlation between the preservation of verbal memory and suppression of CCL24 expression in the group that was in the 70s (Poisson correlation, r = 0.46, p < 0.05). These results suggest that ACS may preserve verbal episodic memory, probably owing to CCL24 suppression in the blood, especially in elderly participants., Competing Interests: The authors declare no conflict of interest.

Enterococcus faecalis is a resident lactic acid bacterium in the human intestine. Its immunostimulatory action was reported to be enhanced by heat sterilization. To investigate its beneficial actions, we evaluated the ability of 10 E. faecalis strains to induce interleukin-12 (IL-12) production in a mouse macrophage cell line, J774.1 and found that the strain, E. faecalis IC-1, had a potent IL-12-inducing ability. Furthermore, we investigated the underlying mechanism by treating IC-1 cells with RNase or lysozyme. Its activity almost disappeared and an antagonist of Toll-like receptor (TLR) 7 inhibited this activity. Moreover, lysozyme-treated IC-1 bacteria were not phagocytized by J774.1 cells, and did not induce IL-12 production. Based on our results, we propose that macrophages recognize the cell wall components of IC-1, leading to phagocytosis. The IC-1 RNA is then recognized by TLR7, which induces the production of IL-12.

Chlorogenic acid (CHA) and caffeic acid (CA) are phenolic compounds found in coffee, which inhibit oxidative stress-induced interleukin (IL)-8 production in intestinal epithelial cells, thereby suppressing serious cellular injury and inflammatory intestinal diseases. Therefore, we investigated the anti-inflammatory mechanism of CHA and CA, both of which inhibited hydrogen peroxide (H₂O₂)-induced IL-8 transcriptional activity. They also significantly suppressed nuclear factor kappa-light-chain-enhancer of activated B cells ( NF-κB ) transcriptional activity, nuclear translocation of the p65 subunit, and phosphorylation of IκB kinase (IKK). Additionally, upstream of IKK, protein kinase D (PKD) was also suppressed. Finally, we found that they scavenged H₂O₂-induced reactive oxygen species (ROS) and the functional moiety responsible for the anti-inflammatory effects of CHA and CA was the catechol group. Therefore, we conclude that the presence of catechol groups in CHA and CA allows scavenging of intracellular ROS, thereby inhibiting H₂O₂-induced IL-8 production via suppression of PKD-NF-κB signaling in human intestinal epithelial cells.

Food allergy is a serious problem for infants and young children. Induction of antigen-specific oral tolerance is one therapeutic strategy. Enhancement of oral tolerance induction by diet is a promising strategy to prevent food allergy in infants. Thus, in this study, we evaluate the effect of probiotic Lactobacillus gasseri OLL2809 (LG2809) on oral tolerance induction in a mouse model. The degree of oral tolerance induction was evaluated by measuring the proliferation and level of IL-2 production of splenic CD4+ T cells from DO11.10 mice fed ovalbumin (OVA) alone or OVA with LG2809. Oral administration of LG2809 significantly decreased the rate of proliferation and IL-2 production by CD4+ T cells from OVA-fed mice. LG2809 increased a ratio of CD4+ T-cell population, producing high levels of IL-10 and having strong suppressive activity. Moreover, LG2809 increased a ratio of plasmacytoid dendritic cells (pDCs) among the lamina propria (LP) in small intestine. When used as antigen presenting cells to naïve CD4+ T cells from DO11.10 mice, LP cells from BALB/c mice fed LG2809 induced higher IL-10 production and stronger suppressive activity than those from non-treated mice. These results suggest that oral administration of LG2809 increases the population of pDCs in the LP, resulting in the enhancement of oral tolerance induction by increasing the ratio of effector regulatory T cells. LG2809 could, therefore, act as a potent immunomodulator to prevent food allergies by promoting oral tolerance.

Our goal in this study was to determine whether or not anserine/carnosine supplementation (ACS) is capable of preserving cognitive function of elderly people. In a double-blind randomized controlled trial, volunteers were randomly assigned to an ACS or placebo group at a 1:1 ratio. The ACS group took 1.0 g of an anserine/carnosine (3:1) formula daily for 3 months. Participants were evaluated by psychological tests before and after the 3-month supplementation period. Thirty-nine healthy elderly volunteers (60-78 years old) completed the follow-up tests. Among the tests, delayed recall verbal memory assessed by the Wechsler Memory Scale-Logical Memory showed significant preservation in the ACS group, compared to the placebo group (p = 0.0128). Blood analysis revealed a decreased secretion of inflammatory cytokines, including CCL-2 and IL-8, in the ACS group. MRI analysis using arterial spin labeling showed a suppression in the age-related decline in brain blood flow in the posterior cingulate cortex area in the ACS group, compared to the placebo group (p = 0.0248). In another randomized controlled trial, delayed recall verbal memory showed significant preservation in the ACS group, compared to the placebo group (p = 0.0202). These results collectively suggest that ACS may preserve verbal episodic memory and brain perfusion in elderly people, although further study is needed.

Background: Spontaneous isolated superior mesenteric artery dissection is a rare disease that may cause bowel ischemia or aneurysm rupture and subsequent death. Thus, the establishment of a correct diagnosis in the early stage is quite important., Objective: To describe the presentation of 3 patients diagnosed with spontaneous isolated supramesenteric artery dissection and briefly summarize the diagnostic procedure, treatment, and clinical course., Case Reports: We experienced three cases of isolated mesenteric artery dissection in the past 5 years. A definitive diagnosis was obtained by abdominal spiral computed tomography in two cases and angiography in one case. All patients were provided anticoagulation therapy., Conclusion: One patient died of bowel ischemia, 2 were discharged within 21 days without complications, and one was able to discontinue anticoagulation therapy 12 months after discharge. The remaining patient has continued warfarin, making it difficult to determine the end point of anticoagulation., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Chlorogenic acid (CHA) is an antioxidant polyphenol prevalent in human diet, with coffee, fruits, and vegetables being its main source. Effects of CHA and CHA metabolites were evaluated on the IL-8 production in human intestinal Caco-2 cells induced by combined stimulation with tumour necrosis factor alpha (TNFα) and H2O2. CHA and caffeic acid (CA) inhibited TNFα- and H2O2-induced IL-8 production. We also examined the in vivo effects of CHA and CA using dextran sulphate sodium (DSS)-induced colitis in mice. CHA attenuated DSS-induced body weight loss, diarrhea, fecal blood, and shortening of colon and dramatically improved colitis histological scores. Furthermore, increases in the mRNA expression of colonic macrophage inflammatory protein 2 and IL-1β, which were induced by DSS, were significantly suppressed by CHA supplementation. These results suggest that dietary CHA use may aid in the prevention of intestinal inflammatory conditions., (Copyright © 2014 Elsevier Ltd. All rights reserved.)
