Abstract	Desmoid-type fibromatosis is a relatively rare disease, often associated with familial adenomatous polyposis and a history of abdominal surgery. A 43-year-old male patient presented with abdominal pain and contrast-enhanced CT showed a mass in the lower abdomen. The mass was a 4×4×3 cm white, dense tumor with a wreath-like arrangement of eosinophilic spindle-shaped cells. Immunostaining showed KIT(-), CD34(-), desmin(-), β-catenin(+), SMA(few+), and the diagnosis was desmoid-type fibrosis. Six months after surgery, there was no apparent recurrence.

Abstract	Aim: Total neoadjuvant therapy (TNT) for locally advanced rectal cancer (LARC) is rapidly spreading. The robotic surgical techniques to approach lateral invasion, such as that of the pelvic plexus, have not yet been established. In this technical note, we present a video illustrating a surgical technique for lateral invasion using our novel technique and discuss its pitfalls. Method: We present the case of a 65-year-old man with LARC. Robotic surgery was performed after TNT using the da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA). The surgical procedure was as follows: (1) D3 lymph node dissection around the inferior mesenteric artery using a medial-to-lateral approach; (2) rectal mobilization; (3) dissection of the ureterohypogastric fascia and ureter; and (4) combined resection of the hypogastric nerve and pelvic plexus. The key surgical point for sidewall invasion is the resection extent. Dividing the resection extent into three areas is important: zone A, which contains the pelvic plexus and is closest to the tumour; zone B, which contains the iliac vessels; and zone C, the most lateral zone, which contains the obturator nerves. This allows organ and function preservation by resecting only the smallest organ that truly requires R0 resection. Results: The operating time was 333 min, console time was 232 min, and blood loss was 0 mL. The circumferential resection margin was 10 mm, and an R0 resection was achieved. Conclusion: We introduced a novel approach for robotic surgery after TNT for LARC with sidewall invasion. This technique can be performed safely and may help standardize 'beyond total mesorectal excision'.

Abstract	Application of poly-aluminum chloride (PACl) coagulant is a popular mode of water treatment worldwide because of the high capacity of PACl to neutralize charge. The manufacture and use of PACls with various basicities in different regions around the world suggest that the characteristics of the raw water are important determinants of the efficacy of PACl application. However, attention has not been fully paid to the effects of water quality other than the substances to be removed. In this study, two typical PACls with different basicities were used to investigate why the performance of PACls depends on the characteristics of the raw water.

Abstract	Site-specific recombination (SSR) systems are employed in many genetic mobile elements, including temperate phages, for their integration and excision. Recently, they have also been used as tools for applications in fields ranging from basic to synthetic biology. SPβ is a temperate phage of the Siphoviridae family found in the laboratory standard Bacillus subtilis strain 168. SPβ encodes a serine-type recombinase, SprA, and recombination directionality factor (RDF), SprB. SprA catalyzes recombination between the attachment site of the phage, attP, and that of the host, attB, to integrate phage genome into the attB site of the host genome and generate attL and attR at both ends of the prophage genome. SprB works in conjunction with SprA and switches from attB/attP to attL/R recombination, which leads to excision of the prophage. In the present study, we took advantage of this highly efficient recombination system to develop a site-specific integration and excision plasmid vector, named pSSβ. It was constructed using pUC plasmid and the SSR system components, attP, sprA and sprB of SPβ. pSSβ was integrated into the attB site with a significantly high efficiency, and the resulting pSSβ integrated strain also easily eliminated pSSβ itself from the host genome by the induction of SprB expression with xylose. This report presents two applications using pSSβ that are particularly suitable for gene complementation experiments and for a curing system of SPβ prophage, that may serve as a model system for the removal of prophages in other bacteria.

Abstract	Application of poly-aluminum chloride (PACl) coagulant is a popular mode of water treatment worldwide because of the high capacity of PACl to neutralize charge. The manufacture and use of PACls with various basicities in different regions around the world suggest that the characteristics of the raw water are important determinants of the efficacy of PACl application. However, attention has not been fully paid to the effects of water quality other than the substances to be removed. In this study, two typical PACls with different basicities were used to investigate why the performance of PACls depends on the characteristics of the raw water. We focused on the concentrations of inorganic ions in the raw water. Use of high-basicity PACl (HB-PACl) with a high content of polymeric-colloidal species (Alb+Alc) resulted in very slow floc formation and little turbidity removal in raw water with low concentrations of sulfate ions. The performance of the HB-PACl was inferior to that of normal-basicity PACl (NB-PACl), although the charge-neutralization capacity of the HB-PACl was higher. Rates of floc formation were strongly correlated with the rate of aluminum precipitation by hydrolysis reaction, which was identified as an indicator for evaluating the compatibility of raw water with PACl treatment. Among the common ions in natural water, the sulfate ion had the greatest ability to hydrolyze and precipitate PACl because of its divalency and tetrahedral structure. This conclusion followed from experimental results showing similar effects for selenate and chromate ions as for sulfate ions and somewhat smaller effects for thiosulfate ions. Bicarbonate ions and natural organic matter affected PACl hydrolysis-precipitation, but chloride ions, nitrate ions, and cations had little effect on PACl hydrolysis-precipitation. Interestingly, the abilities of sulfate ions to hydrolyze HB-PACl and NB-PACl were very similar, but bicarbonate ions were less effective in hydrolyzing HB-PACl than NB-PACl, and bicarbonate ions contributed little to the hydrolysis-precipitation of HB-PACl in raw water with normal alkalinity. Therefore, sufficient coagulation with HB-PACl therefore usually requires a certain concentration of sulfate ions in water to be treated. The implication is that which anions are most influential to the hydrolysis-precipitation of PACl, and thus to PACl's coagulation ability depends on the constituents of the PACl.

Abstract	Background: Acinar cell carcinoma of the pancreas is a rare exocrine malignancy representing less than 1% of all pancreatic neoplasms. It has been reported that it responds to treatment differently from pancreatic ductal adenocarcinoma and the treatment algorithm for acinar cell carcinoma usually depends on the stage of the respective tumor and the patient's current status. Case presentation: A 60-year-old man presented with upper abdominal pain and anorexia. Abdominal ultrasonography showed a large-sized hepatic mass and he was referred to our hospital. Contrast-enhanced computed tomography demonstrated a 110-mm low-density area occupying the right hemi-liver and an enhanced mass of 70 × 56 mm in the tail of the pancreas, which seemed to directly infiltrate into the spleen. The case was diagnosed as acinar cell carcinoma with a simultaneous liver metastasis identified by liver biopsy. Upfront resection of pancreatic cancer with distant metastasis might not be considered as an optimal choice, and in this case chemotherapy was administered prior to curative resection. Chemotherapy using the modified FOLFIRINOX regimen was undertaken, resulting in a partial remission; the liver tumor reduced in size from 110 to 47 mm and the pancreatic tumor from 70 to 40 mm. The patient then safely underwent curative hepatic resection with distal pancreato-splenectomy. Histological examinations revealed small-sized atypical cells with large nuclei that had formed acinar patterns, and immunostaining with trypsin was positive in tumor cells, which was in accordance with acinar cell carcinoma. More than 3 years later, the patient is doing well without any recurrence. Conclusion: Aggressive and curative surgery in combination with chemotherapy such as FOLFIRINOX could be a treatment option to achieve long-term survival in cases of acinar cell carcinoma with liver metastases.

Abstract	Introduction: Low health literacy (HL) is associated with poor surgical outcomes in patients with abdominal tumors, despite enhanced recovery programs. However, the relationship between HL and postoperative outcomes, including health-related quality of life (HRQOL) and physical functions, has been unclear in patients with abdominal tumors receiving perioperative rehabilitation programs (PRPs). Our objective was to identify associations of HL with postoperative functional and general outcomes in patients with abdominal tumors undergoing surgery and PRPs, controlling for critical covariates. Materials and methods: The prospective cohort study was conducted from April 2020 to December 2021 in a single acute care hospital in Akita City, Japan. Out of 112 consecutive older adults with abdominal tumors referred to PRPs before surgery for tumors, 101 participated. Three patients declined undergoing follow-up assessment, and thus 97 were analyzed. Demographic data, comorbidities, education, surgical procedure, frailty status, cognitive functions, physical activity, nutritional status, tumor sites, types, and stages were collected as covariates at baseline. All participants underwent PRPs. HL was measured using the Japanese version of the European Health Literacy Survey Questionnaire, a comprehensive HL measurement. Primary endpoints were changes in HRQOL, measured using the EuroQol 5-dimension 5-level (EQ-5D-5L) index and EuroQol-visual analog scale (EQ-VAS), and physical functions (chair-stand ability, usual gait speed, and grip strength) from before surgery to discharge. Secondary endpoints were 90-day readmissions, postoperative complications, and length of hospital stay. Multivariate regression with inverse probability weighting, using propensity scores, estimeted associations of HL with the outcomes. Results: Of the 97 patients (36 [37.1%] women, mean [standard deviation] age 74.4 [6.3] years), 42 (43.3%) reported low HL. At baseline, patients with low HL exhibited worse EQ-5D-5L scores (P = .001), EQ-VAS values (P = .03), chair-stand ability (P = .001), and gait speed (P = .03) than controls. Low HL was associated with a low risk of grip strength declines (risk ratio, 0.13; 95% confidence interval, 0.12-0.99) but not with any other outcome. Discussion: There appeared to be no apparent associations of HL with surgical outcomes in patients with abdominal tumors receiving PRPs. Thus, HL might not be a crucial predictor of surgical outcomes when combined with PRPs.

Abstract	Purpose: Health literacy (HL) is pivotal in managing patients with abdominal cancer and is associated with treatment outcomes and care experience. However, detailed characteristics of HL and their associations with clinical features remain uncertain in the population. Therefore, we aimed to comprehensively investigate HL and its associations with clinical characteristics in older patients with abdominal tumours. Methods: We analysed 103 older patients with abdominal tumours prescribed perioperative rehabilitation programs in an acute care hospital. The Japanese version of the European Health Literacy Survey Questionnaire was used to measure comprehensive HL. Multivariate ordinal or linear regression analyses were used to explore the associations between HL and the following clinical characteristics: physical status, physical function, cardiopulmonary function, levels of activities of daily living (ADL), physical activity level, and health-related quality of life (HR-QoL). All regression analyses included patient demographics as covariates. Results: Approximately 50%-70% of the participants had difficulty accessing and appraising health-related information, and 20%-45% thought it was difficult to understand and apply the information. The percentage of limited HL levels in general HL, three health-relevant domains, and four competencies ranged from 62% to 83%. Moreover, regression analyses revealed that lower HL was associated with worse physical status/function, lower ADL, and poorer HR-QoL. Conclusion: Most older patients with abdominal tumours have limited HL, which may lead them to make treatment decisions without fully understanding what healthcare providers advise. Furthermore, patients with lower HL are at a higher risk of poor treatment outcomes because of their worse clinical characteristics.

Abstract	To the best of my knowledge, only 19 cyclic and 8 linear C35 terpenes have been identified to date, and no family name was assigned to this terpene class until recently. In 2011, it was proposed that these C35 terpenes should be called sesquarterpenes. This review highlights the biosynthesis of two kinds of sesquarterpenes (C35 terpenes) that are produced via cyclization of a linear C35 isoprenoid in Bacillus and Mycobacterium species. In Bacillus species, a new type of terpene cyclase that has no sequence homology with any known terpene synthases, as well as a bifunctional terpene cyclase that biosynthesizes two classes of cyclic terpenes with different numbers of carbons as natural products, have been identified. On the other hand, in Mycobacterium species, the first bifunctional Z-prenyltransferase has been found, but a novel terpene cyclase and a unique polyprenyl reductase remain unidentified. The identification of novel enzyme types should lead to the discovery of many homologous enzymes and their products including novel natural compounds. On the other hand, many enzymes responsible for the biosynthesis of natural products have low substrate specificities in vitro. Therefore, to find novel natural products present in organisms, the multifunctionality of enzymes in the biosynthetic pathway of natural products should be analyzed.

Abstract	Soil organic matters may inhibit the pozzolanic reaction, and thus influence the strength development of soil-employed construction materials. To understand their interaction, the effect of lignosulfonate, here used as model soil organic matter, on the pozzolanic reaction was investigated through batch experiments. Lignosulfonate inhibited the pozzolanic reaction, suppressing calcium silicate hydrate (C-S-H) formation. The suppression did not take place in a continuous way with the addition of lignosulfonate but was triggered at a certain dosage of lignosulfonate. We propose that the inhibition was primarily due to formation of Si-(Ca)-lignosulfonate complex. Such interaction may illustrate the inhibition of the pozzolanic reaction by organic matters in soils at alkaline activation. Below the threshold, lignosulfonate allowed C-S-H formation though modified its structure, which also suggested the possibility of soil organic matters to influence the strength development of construction materials in coexistence of C-S-H formation.
