Revisiting the use of the EORTC QLQ-STO22 to assess health-related quality of life of patients with gastric cancer: incorporating updated treatment options and cross-cultural perspectives. Gastric Cancer 2024; 27:722-734. [PMID: 38668819 PMCID: PMC11193686 DOI: 10.1007/s10120-024-01492-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Accepted: 03/10/2024] [Indexed: 06/23/2024]
Abstract
BACKGROUND The EORTC QLQ-STO22 (QLQ-STO22) is a firmly established and validated measure of health-related quality of life (HRQoL) for people with gastric cancer (GC), developed over two decades ago. Since then there have been dramatic changes in treatment options for GC. Also, East Asian patients were not involved in the development of QLQ-STO22, where GC is most prevalent and the QLQ-STO22 is widely used. A review with appropriate updating of the measure was planned. This study aims to capture HRQoL issues associated with new treatments and the perspectives of patients and health care professionals (HCPs) from different cultural backgrounds, including East Asia. METHODS A systematic literature review and open-ended interviews were preformed to identify potential new HRQoL issues relating to GC. This was followed by structured interviews where HCPs and patients reviewed the QLQ-STO22 alongside new issues regarding relevance, importance, and acceptability. RESULTS The review of 267 publications and interviews with 104 patients and 18 HCPs (48 and 9 from East Asia, respectively) generated a list of 58 new issues. Three of these relating to eating small amounts, flatulence, and neuropathy were recommended for inclusion in an updated version of the QLQ-STO22 and covered by five additional questions. CONCLUSIONS This study supports the content validity of the QLQ-STO22, suggesting its continued relevance to patients with GC, including those from East Asia. The updated version with additional questions and linguistic changes will enhance its specificity, but further testing is required.

Abstract
BACKGROUND Foreign body granulomas are postoperative inflammatory reactions to surgical materials within the body. Traditionally, sutures have been the leading cause of foreign body granulomas in the abdomen, commonly referred to as "suture granuloma". However, the use of polymer clips in modern surgeries has introduced new challenges, and reports of intra-abdominal foreign body granulomas caused by surgical clips are limited. Herein, we present a case of an intra-abdominal foreign body granuloma formed due to polymer clips. CASE PRESENTATION A 45-year-old woman who underwent laparoscopic resection for sigmoid colon adenocarcinoma subsequently developed a suspected lymph node recurrence during follow-up. Imaging showed an enlarging mass adjacent to the inferior mesenteric artery with increased fluorodeoxyglucose uptake. Laparoscopic surgical resection revealed the formation of a foreign body granuloma in response to the polymer clips. CONCLUSIONS This case suggests that nonabsorbable polymer clips can induce granulomatous reactions postoperatively, and the appearance of lymph node recurrence may be foreign body granulomas.

Abstract
A cemental tear (CeT) is a definitive clinical entity and its radiographic appearance is well known in single-rooted teeth. However, the imaging features of CeT in multi-rooted teeth have not been clarified. We report a case of CeT which arose in the maxillary first molar and exhibited an unusual appearance in cone-beam computed tomography images. The torn structure was verified as cementum by micro-computed tomography and histological analysis. The hypercementosis, most likely induced by occlusal force, might have been torn from the root by a stronger occlusal force caused by the mandibular implant. An unusual bridging structure was created between the two buccal roots. These features may occur in multi-rooted teeth with long-standing deep pockets and abscesses that are resistant to treatment.

Cells 2024; 13:348.

Abstract
Regenerative endodontic procedures (REPs) are promising for dental pulp tissue regeneration; however, their application in permanent teeth remains challenging. We assessed the potential combination of an REP and local dental pulp cell (DPC) transplantation in the mature molars of C57BL/6 mice with (REP + DPC group) or without (REP group) transplantation of DPCs from green fluorescent protein (GFP) transgenic mice. After 4 weeks, the regenerated tissue was evaluated by micro-computed tomography and histological analyses to detect odontoblasts, vasculogenesis, and neurogenesis. DPCs were assessed for mesenchymal and pluripotency markers. Four weeks after the REP, the molars showed no signs of periapical lesions, and both the REP and REP + DPC groups exhibited a pulp-like tissue composed of a cellular matrix with vessels surrounded by an eosin-stained acellular matrix that resembled hard tissue. However, the REP + DPC group had a broader cellular matrix and uniquely contained odontoblast-like cells co-expressing GFP. Vasculogenesis and neurogenesis were detected in both groups, with the former being more prominent in the REP + DPC group. Overall, the REP was achieved in mature mouse molars and DPC transplantation improved the outcomes by inducing the formation of odontoblast-like cells and greater vasculogenesis.

Abstract
PURPOSE In this research, we analyzed the expression of serpinB9 in hepatoblastoma and investigated the factors which enhance its expression. METHOD SerpinB9 expression in hepatoblastoma cell lines and macrophages co-cultured with each other or stimulated by anticancer agents was examined using RT-qPCR and western blotting. Immunohistochemistry for SerpinB9 in hepatoblastoma specimens was performed. Single-cell RNA-sequence data for hepatoblastoma from an online database were analyzed to investigate which types of cells express SerpinB9. RESULT HepG2, a hepatoblastoma cell line, exhibited increased expression of SerpinB9 when indirectly co-cultured with macrophages. Immunohistochemistry for the specimens demonstrated that serpinB9 is positive not in hepatoblastoma cells but in macrophages. Single-cell RNA sequence analysis in tissues from hepatoblastoma patients showed that macrophages expressed SerpinB9 more than tumor cells did. Co-culture of macrophages with hepatoblastoma cell lines led to the enhanced expression of SerpinB9 in both macrophages and cell lines. Anticancer agents induced an elevation of SerpinB9 in hepatoblastomas cell lines. CONCLUSION In hepatoblastoma, SerpinB9 is thought to be more highly expressed in macrophages and enhanced by interaction with hepatoblastoma cell.

Abstract
The effects of microwave drying conditions of a Paracoccus carotinifaciens culture solution on astaxanthin Z-isomerization and degradation were investigated. The microwave drying significantly increase the ratio of astaxanthin Z-isomers, and the higher the microwave power and the longer the drying time, the higher the total Z-isomer ratio of astaxanthin, but such conditions also accelerated astaxanthin degradation. We found that the addition of powdered oils enhanced the Z-isomerization reaction. For example, when the P. carotinifaciens culture solution was dried at 1000 W power for 5 min without and with powdered rapeseed oil, total Z-isomer ratios of astaxanthin in resulting dried powder were 14.9 and 47.4%, respectively. Furthermore, the storage test of the dried P. carotinifaciens powder showed that astaxanthin Z- isomers were stable at 4℃ in a low-oxygen atmosphere. As astaxanthin Z-isomers have greater bioavailability and potentially exhibit superior biological activities than the all-E-isomer, the dried P. carotinifaciens powder obtained by the method of this study is expected to be used as a value-added astaxanthin source.

Abstract
The use of Paracoccus carotinifaciens-derived natural astaxanthin as an alternative to synthetic astaxanthin has attracted considerable attention from the aquaculture industry. Furthermore, to enhance the bioavailability of astaxanthin, its "Z-isomerization" has been actively studied in recent years. This study investigated the effects of feeding a diet containing astaxanthin rich in the all-E- or Z-isomers derived from P. carotinifaciens on the pigmentation and astaxanthin concentration in rainbow trout (Oncorhynchus mykiss) flesh. Z-Isomer-rich astaxanthin was prepared from the P. carotinifaciens-derived all-E-isomer by thermal treatment in fish oil, and the prepared all-E-isomer-rich astaxanthin diet (E-AST-D; total Z-isomerratio = 9.1%) and Z-isomer-rich astaxanthin diet (Z-AST-D; total Z-isomer ratio of astaxanthin = 56.6%) were fed to rainbow trout for 8 weeks. The feeding of Z-AST-D resulted in greater pigmentation and astaxanthin accumulation efficiency in the flesh than those fed E-AST-D. Specifically, when E-AST-D was fed to rainbow trout, the SalmoFan score and astaxanthin concentration of the flesh were 22.1±1.4 and 1.36±0.71 μg/g wet weight, respectively, whereas when Z-AST-D was fed, their values were 26.0±2.5 and 5.33±1.82 μg/g wet weight, respectively. These results suggest that P. carotinifaciens-derived astaxanthin Z- isomers prepared by thermal isomerization are more bioavailable to rainbow trout than the all-E-isomer.

Abstract
This study investigated the effects of the preparation form of astaxanthin on egg yolk pigmentation and egg quality in laying hens. The following four astaxanthin sources were prepared in this study: (1) dried cell powder of Paracoccus carotinifaciens (Panaferd-AX), (2) fine cell powder of P. carotinifaciens (Panaferd-P), (3) astaxanthin oil suspension, and (4) water-soluble astaxanthin powder. These astaxanthin preparations were added to the basal diet at a final concentration of 2 mg/kg and fed to White Leghorn laying hens for 14 days. Although the administration of these astaxanthin preparations did not largely affect egg quality (i.e., egg weight, yolk weight, albumen height, and Haugh unit), feeding significantly improved astaxanthin concentration and yolk color fan score. When water-soluble astaxanthin powder was fed, the yolk astaxanthin concentration and color fan score were most improved, followed by Panaferd-P. These results indicated that astaxanthin pulverization and water solubilization significantly improved its bioavailability in laying hens. Furthermore, although diets rich in (all-E)-astaxanthin were fed to the hens, approximately 30% of astaxanthin was present as the Z-isomers in the egg yolk. These findings may contribute to improving not only the egg quality but the nutritional value of hen eggs.

Abstract
Liver transplantation (LT) is the only life-saving option when acute-on-chronic liver failure (ACLF) does not improve with conservative therapy. Acute pancreatitis (AP) can cause chronic liver disease progression to ACLF. However, deceased donor LT for patients with AP has had mixed results, and no consensus has been established regarding the indication for LT. We report the first successful living donor LT (LDLT) for ACLF caused by severe AP. The 38-year-old patient with alcoholic liver disease was transferred to our institute with worsening refractory ascites. During the pretransplant workup, she developed severe acute necrotizing pancreatitis, resulting in grade 3 ACLF. The patient's clinical course was further complicated by high levels of donor-specific antibodies and immune thrombocytopenia. The AP gradually improved after intensive care combined with artificial liver support. The patient successfully underwent urgent LDLT with upfront splenectomy and desensitization therapy, including plasm exchange, high-dose intravenous immunoglobulin, and anti-thymocyte globulin. No infection or recurrence of AP was observed postoperatively. We conclude that LDLT is a feasible option for ACLF patients caused by severe AP if a deceased donor is not readily available.

Abstract
Introduction In this study, we report that a proteoglycans (PGs)-layer between the bone and titanium dioxide (TiO2) surface after osseointegration improved the calcification capacity and immunotolerance of human bone marrow mesenchymal stem cells (hBMSCs) on TiO2. Alkaline treatment of TiO2 is a method for promoting osteogenesis in hBMSCs. We hypothesized that promotion of osteogenesis due to alkaline treatment was caused by changing PGs-layer on TiO2. Objective This study aimed to analyze whether alkaline treatment of TiO2 affects PGs-layer formation and immunotolerance in hBMSCs. Methods The topology and wettability of the alkaline-treated titanium (Ti-Al) and unprocessed titanium (Ti-MS) surfaces were characterized. Initial cell attachment, cell proliferation, calcification capacity, alkaline phosphatase activity, PGs-layer formation, PGs function, and the expression of osteogenic and immunotolerance-related genes were analyzed. The conditioned medium (CM) from hBMSCs grown on Ti-Al and Ti-MS was added to macrophages (hMps) and Jurkat cells, and immunotolerance gene expression in these cells was analyzed. Results hBMSCs cultured on Ti-Al showed increased initial cell attachment, cell proliferation, PG-layer formation, and osteogenic capacity compared with hBMSCs on Ti-MS. Gene expression of indoleamine 2,3-dioxygenase (IDO) in the hBMSCs cultured on Ti-Al was higher than that in the hBMSCs on Ti-MS. CM from hBMSCs did not affect markers of M1 and M2 macrophages in hMps. CM from hBMSCs cultured on Ti-Al altered the gene expression of Foxp3 in Jurkat cells compared to that of CM from hBMSCs on Ti-MS. Significance These results suggest that alkaline treatment of TiO2 altered PGs-layer formation, and changed the osteogenesis and immunotolerance of hBMSCs.

Abstract
The effects of light-emitting diode (LED) irradiation characterized by different emission wavelengths on the E/Z-isomerization and degradation of astaxanthin were investigated. LED irradiation slightly promoted Z-isomerization of astaxanthin, whereas the all-E-isomerization was highly efficiently promoted at specific wavelengths, especially at 365 nm. Astaxanthin isomers did not degrade significantly when dissolved in ethanol and subjected to LED irradiation conditions for 300 min. However, significant degradation was achieved when ethyl acetate was used for dissolution, and the samples were irradiated at the wavelength of 405 nm. The addition of α-tocopherol suppressed the photodegradation of astaxanthin. LED irradiation significantly affected the physical properties of astaxanthin Z-isomers. Irradiation with 365, 405, and 470 nm LEDs enhanced the color value (redness) and crystallinity of the Z-isomers via an all-E-isomerization reaction. These findings can contribute to the development of technologies that can arbitrarily control the E/Z-isomer ratio and physical properties of astaxanthin.

Abstract
Background The principle of hepatoblastoma (HB) treatment is complete resection. The removal of tumor-bearing section(s) or hemiliver is widely accepted. However, neither the standardized anterior approach for right hepatectomy nor parenchymal sparing anatomical liver resection has been described for HB. Methods We retrospectively reviewed the clinical course of two pediatric HB patients who underwent extended right hepatectomy using the anterior approach with the liver hanging maneuver and one who underwent parenchymal sparing anatomical liver resection of S4 apical+S8 ventral/dorsal+S7. The critical aspects of surgical techniques are described in detail. Results In all three patients, R0 resection was achieved without complications and are currently alive without recurrence after an average follow-up of 23 months. Intraoperative cardiac hemodynamics were stable, even in a trisomy 18 patient with cardiac disease. Conclusions Our findings suggest that these innovative techniques established in adults are safe and feasible for HB in children. These techniques also allow optimal anatomical liver resection to accomplish curative surgery while maintaining the functional reserve of the remnant liver.

Abstract
Hepatic venous outflow obstruction (HVOO) is a rare but critical vascular complication after adult living donor liver transplantation. We categorized HVOOs according to their morphology (anastomotic stenosis, kinking, and intrahepatic stenosis) and onset (early-onset < 3 mo vs. late-onset ≥ 3 mo). Overall, 16/324 (4.9%) patients developed HVOO between 2000 and 2020. Fifteen patients underwent interventional radiology. Of the 16 hepatic venous anastomoses within these 15 patients, 12 were anastomotic stenosis, 2 were kinking, and 2 were intrahepatic stenoses. All of the kinking and intrahepatic stenoses required stent placement, but most of the anastomotic stenoses (11/12, 92%) were successfully managed with balloon angioplasty, which avoided stent placement. Graft survival tended to be worse for patients with late-onset HVOO than early-onset HVOO (40% vs. 69.3% at 5 y, p = 0.162) despite successful interventional radiology. In conclusion, repeat balloon angioplasty can be considered for simple anastomotic stenosis, but stent placement is recommended for kinking or intrahepatic stenosis. Close follow-up is recommended in patients with late-onset HVOO even after successful treatment.

Abstract
Introduction We recently demonstrated the bone-forming potential of medium-cross-linked recombinant collagen peptide (mRCP) in animal models of bone defects. However, these studies were limited to a 4-week observation period; therefore, in the present study, we aimed to further evaluate mRCP as a suitable bone graft material for the alveolar cleft by analyzing its bone-forming potential, osteogenic-inducing ability, and biodegradation over an extended period of 12 weeks, using a rat critical-size calvarial defect model. Methods Using Sprague-Dawley rats, we created critical-size calvarial defects through a surgical procedure. The defects were then filled with 3 mg of mRCP (mRCP group) or 18 mg of Cytrans® (CA) granules, which has a carbonate apatite-based composition resembling natural bone, was used as a reference material (CA group). For negative control, the defects were left untreated. Bone volume, total bone volume (bone volume including CA granules), and bone mineral density (BMD) in the defect were assessed using micro-computed tomography (μ-CT) at 0, 4, 8, and 12 weeks after implantation. Using histomorphometric analyses of hematoxylin and eosin (H&E)-stained sections, we measured the amount of newly formed bone and total newly formed bone (new bone including CA granules) in the entire defect site, as well as the amount of newly formed bone in the central side, two peripheral sides (left and right), periosteal (top) side, and dura mater (bottom) side. In addition, we measured the amount of residual bone graft material in the defect. Osteoclasts and osteoblasts in the newly formed bone were detected using tartrate-resistant acid phosphatase (TRAP) and alkaline phosphatase (ALP) staining, respectively. Results Bone volume in the mRCP group increased over time and was significantly larger at 8 and 12 weeks after surgery than at 4 weeks. The bone volume in the mRCP group was greater than that of the CA and control groups at 4, 8, and 12 weeks after implantation, and while the total bone volume was greater in the CA group after 4 and 8 weeks, the mRCP group had comparable levels of total bone volume to that of the CA group at 12 weeks after implantation. The BMD of the mRCP group reached similar levels to native calvaria bone at the same time point. H&E-stained sections revealed a larger amount of newly formed bone 12 weeks after implantation in the mRCP group compared to that of the CA and control groups. The total newly formed bone at 12 weeks after implantation was on par with that in the CA group. Furthermore, at the defect site, the area of newly formed bone was larger on the peripheral and dura mater sides. Notably, the number of osteoclasts in the mRCP group was higher than in the CA and control groups and peaked 8 weeks after implantation, which coincided with the timing of the greatest resorption of mRCP. Although the ALP-positive area was greater in the mRCP group compared to other groups, we did not detect any significant changes in the number of osteoblasts over time. Conclusion This study demonstrated the bone-forming potential of mRCP over an extended period of 12 weeks, suggesting that mRCP sufficiently resists resorption to promote bone formation through induction of osteoclast activation in the late stages of the healing period.

Abstract
Aphanothece sacrum, a freshwater cyanobacterium, is an edible cyanobacterial strain. We identified two compounds belonging to the oxylipin family that possess UV-absorbing abilities and accumulate in the dried sample of A. sacrum. The compounds, named saclipin A and saclipin B, exhibited strong UV-absorption properties with the absorption maxima at 316 and 319 nm, respectively, and the molar extinction coefficients of 26,454 and 30,555 M-1 cm-1, respectively. The chemical structures of saclipins A and B have been elucidated, revealing that they have an all-E and a 12Z isomeric relationship within the triene structure. The saclipins could be isomerized by photoirradiation, with the cis-form saclipin B proving to be more stable in methanol, ethanol, or acetonitrile. Under drought stress conditions, the accumulation of saclipins A and B in A. sacrum was found to be increased 20- and 10-fold, respectively. Purified saclipins from A. sacrum showed biocompatibility and valuable bioactivities. Specifically, saclipins exhibited radical scavenging activity, maintaining their activity even 40 min after the reaction began. Additionally, they demonstrated inhibitory activity against glycation of elastin and collagen, which are constituents of dermal tissue. Notably, saclipins showed higher activity than the well-known glycation inhibitor aminoguanidine against collagen glycation.

Abstract
PURPOSE This study investigated the expression of interleukin 32 (IL-32) in hepatoblastoma, the most common primary pediatric liver tumor, and its possible roles in tumorigenesis. METHODS IL-32 expression was investigated in two hepatoblastoma cell lines (Hep G2 and HuH 6) in the steady state and after co-culture with macrophages by RNA-seq analysis and RT-qPCR, and after stimulation with chemotherapy. Cultured macrophages were stimulated by IL-32 isoforms followed by RT-qPCR and western blot analysis. IL-32 immunohistochemical staining (IHC) was performed using specimens from 21 hepatoblastoma patients. Clustering analysis was also performed using scRNA-seq data downloaded from Gene Expression Omnibus. RESULTS The IL-32 gene is expressed by hepatoblastoma cell lines; expression is upregulated by paracrine cell-cell communication with macrophages, also by carboplatin and etoposide. IL-32 causes protumor activation of macrophages with upregulation of PD-L1, IDO-1, IL-6, and IL-10. In the patient pool, IHC was positive only in 48% of cases. However, in the downloaded dataset, IL-32 gene expression was negative. CONCLUSION IL-32 was detected in hepatoblastoma cell lines, but not in all hepatoblastoma patients. We hypothesized that stimulation such as chemotherapy might induce expression of IL-32, which might be a critical mediator of chemoresistance in hepatoblastoma through inducing protumor activation in macrophages.

Differentiation 2023; 133:88-97.

Abstract
This study investigated the expression of sortilin 1 (SORT1) in cultured human dental pulp-derived stem cells (hDPSCs) and its role in their odontoblastic differentiation. Permanent teeth were extracted from five patients, and the dental pulp was harvested for explant culture. Fluorescence-activated cell sorting was used to analyze the outgrowth of adherent cells and cells that had migrated from the tissue margin. SORT1 expression was detected in hDPSCs simultaneously expressing the mesenchymal stem cell markers CD44 and CD90. The odontoblastic differentiation potential of SORT1-positive hDPSCs was examined via staining for alkaline phosphatase (ALP), an early odontoblastic differentiation marker. ALP staining was more intense in SORT1-positive than in SORT1-negative hDPSCs. Consistently, the expression of mRNA encoding SORT1 and p75NTR, a binding partner of SORT1, increased in SORT1-positive hDPSCs during odontoblastic differentiation. In addition, pro-nerve growth factor (NGF), a ligand for SORT1-p75NTR co-receptor, promoted ALP expression in SORT1-positive hDPSCs, and the interaction between SORT1 and p75NTR was detected using a coimmunoprecipitation assay. The function of SORT1 in odontoblastic differentiation was examined via RNA interference using shRNA targeting SORT1. ALP staining intensity in SORT1/shRNA-transfected cells was markedly lower than in control/shRNA-transfected cells. SORT1 knockdown decreased JUN phosphorylation and recruitment of phosphorylated JUN to the ALP promoter. Collectively, these results indicate that SORT1 is involved in the odontoblastic differentiation of hDPSCs through the JUN N-terminal kinases (JNK)/JUN signaling pathway and that the binding of SORT1 and p75NTR plays an important role in this process.

Abstract
INTRODUCTION Solid pseudopapillary neoplasm (SPN) is a rare and low malignant tumor found mainly in young females. There is no standardized procedure for SPN of the pancreatic body and tail in children. In adults, an international consensus on precision anatomy for minimally invasive distal pancreatectomy (MIDP) was established recently (PAM-HBP Surgery Project). The aim of this study is to demonstrate that precision anatomy can also be safely and effectively implemented in the pediatric population. PRESENTATION OF CASE A 12-year-old girl with an incidentally found SPN located in the pancreatic tail was referred to our hospital. She successfully underwent an R0 resection by laparoscopic spleen-preserving distal pancreatectomy (LSPDP) under the concept of precision anatomy. The patient recovered uneventfully and was discharged on day 7. DISCUSSION This is the first successful report of LSPDP under the concept of precision anatomy in children. In accordance with the recommendations from the international consensus, the "anterior approach" was selected to dissect and encircle the splenic artery based on the vascular anatomy identified by preoperative imaging. The dorsal dissection border of the pancreas along the anterior layer above the Gerota's fascia was carefully maintained and the splenic vessels were preserved taking into consideration the low malignant potential of SPN and to decrease the risk of complications associated with splenectomy, which were also the essential issues of the consensus. CONCLUSION The implementation of precision anatomy for pediatric pancreas surgery should facilitate the safe diffusion of MIDP for SPN and other benign or low-malignant tumors in children.

Abstract
The first total synthesis of (+)-tanzawaic acid B, a natural polyketide bearing a pentadienoic ester and octalin moiety, has been accomplished. The synthetic improvement from previous synthetic conditions facilitated our gram-scale synthesis of the chiral octalin that possesses seven stereogenic centers and that is the core skeleton of almost all of the tanzawaic acid family.

Abstract
Dietary astaxanthin exists predominantly as the all-E-isomer; however, certain amounts of the Z-isomers are universally present in the skin, whose roles remain largely unknown. The aim of this study was to investigate the effects of the astaxanthin E/Z-isomer ratio on skin-related physicochemical properties and biological activities using human dermal fibroblasts and B16 mouse melanoma cells. We revealed that astaxanthin enriched in Z-isomers (total Z-isomer ratio = 86.6%) exhibited greater UV-light-shielding ability and skin antiaging and skin-whitening activities, such as anti-elastase and anti-melanin formation activities, than the all-E-isomer-rich astaxanthin (total Z-isomer ratio = 3.3%). On the other hand, the all-E-isomer was superior to the Z-isomers in singlet oxygen scavenging/quenching activity, and the Z-isomers inhibited type I collagen release into the culture medium in a dose-dependent manner. Our findings help clarify the roles of astaxanthin Z-isomers in the skin and would help in the development of novel skin health-promoting food ingredients.

Abstract
Daily consumption of carotenoids is associated with multiple health benefits, but their bioavailability is generally extremely low. In this context, the Z-isomerization is receiving attention as a method for increasing carotenoid bioavailability because this approach is superior to conventional physical approaches. Here we investigated the feasibility of using isothiocyanate-functionalized silica (Si-NCS) as a heterogeneous catalyst for carotenoid isomerization. We found that this catalyst promoted Z-isomerization of (all-E)-carotenoids with high efficiency, e.g., when lycopene and astaxanthin solutions were incubated at 50 °C with 10 mg/mL Si-NCS, their total Z-isomer ratios increased by approximately 80 and 50 %, respectively. Furthermore, the Z-isomerization was successfully performed continuously by introducing carotenoid solution into a column packed with Si-NCS. Materials rich in carotenoid Z-isomers have not been used in practical applications due to high production cost and quality limitations (e.g., low Z-isomer ratio). The use of Si-NCS has sufficient potential to solve both these issues.

Abstract
Coronavirus disease 2019 (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a major global public health event, resulting in a significant social and economic burden. Although COVID-19 was initially characterized as an upper respiratory and pulmonary infection, recent evidence suggests that it is a complex disease including gastrointestinal symptoms, such as diarrhea, nausea, and vomiting. Moreover, it remains unclear whether the gastrointestinal symptoms are caused by direct infection of the gastrointestinal tract by SARS-CoV-2 or are the result of systemic immune activation and subsequent dysregulation of homeostatic mechanisms. This review provides a brief overview of the mechanisms by which SARS-CoV-2 disrupts the integrity of the gastrointestinal barrier including the mechanical barrier, chemical barrier, microbial barrier, and immune barrier.

Abstract
Although most carotenoids in fruits and vegetables exist as the all-E-isomers, several carotenoids accumulated in the skin exist as the Z-isomers. However, the differences in the skin-related biological activities of the all-E- and Z-isomers are largely unknown. This study investigated the effects of E/Z-isomer ratios of lycopene and β-carotene on their ultraviolet (UV)-light-shielding ability and skin-related biological activities (i.e., antioxidant, skin anti-aging, and skin-whitening activities). Z-Isomer-rich lycopene and β-carotene were prepared by thermal isomerization of their all-E-isomers, i.e., the total Z-isomer ratios of lycopene and β-carotene were 97.7 and 89.0%, respectively. The Z-isomers exhibited higher UV-A- and UV-B-shielding abilities and greater skin-related biological activities (e.g., anti-elastase activity, hyaluronic acid production-promoting effect, anti-melanin formation activity, and inhibitory activity for melanin precursor darkening) in several assays than the all-E-isomers. These findings may contribute to understanding the significance of carotenoid Z-isomers in the skin and developing food ingredients that promote skin health.

Abstract
AIM The Japan criteria (Milan criteria + 5-5-500 rule) was established recently to select cirrhotic patients with hepatocellular carcinoma for liver transplantation. We evaluated factors associated with poor prognosis after liver transplantation and investigated whether a further extension of the criteria would be worthwhile. METHODS We retrospectively analyzed 86 patients who underwent liver transplantation for hepatocellular carcinoma at Kumamoto University Hospital since 2004; 69 patients (80.2%) met the Japan criteria (the JCIN group), and 17 patients (19.8%) did not (the JCOUT group). RESULTS The 5-year cancer-specific survival rates of the JCIN group (92.2%) were significantly better than that of the JCOUT group (39.2%; P < .001). In univariable analysis, alfa-fetoprotein and des-gamma-carboxy prothrombin were significant independent factors associated with cancer-specific survival rates. According to the receiver operating characteristic curves, the cutoff values of alfa-fetoprotein and des-gamma-carboxy prothrombin that predicted hepatocellular carcinoma recurrence after liver transplantation were 756 ng/mL and 1976 mAU/mL, respectively. The JCOUT group was divided into 2 subgroups according to alfa-fetoprotein and des-gamma-carboxy prothrombin: low risk (alfa-fetoprotein level <756 ng/mL and des-gamma-carboxy prothrombin level <1976 mAU/mL) and high risk (alfa-fetoprotein level ≥756 ng/mL and/or des-gamma-carboxy prothrombin level ≥1976 mAU/mL). The 5-year cancer-specific survival rate in the low-risk group (67.5%) was significantly better than that in the high-risk group (0%; P < .001). CONCLUSIONS Alfa-fetoprotein levels of <756 ng/mL and des-gamma-carboxy prothrombin levels of <1976 mAU/mL may help identify cirrhotic patients with hepatocellular carcinoma who do not meet the Japan criteria but still benefit from liver transplantation.
