Preoperative evaluation of pleural adhesions with dynamic chest radiography: a retrospective study of 146 patients with lung cancer.

AIM: To assess the utility of dynamic chest radiography (DCR) during the preoperative evaluation of pleural adhesions. MATERIALS AND METHODS: Sequential chest radiographs of 146 patients with lung cancer were acquired during forced respiration using a DCR system. The presence of pleural adhesions and their grades were determined by retrospective surgery video assessment (absent: 121, present: 25). The maximum inspiration to expiration lung area ratio was used as an index for air intake volume. A ratio of ≥0.65 was regarded as insufficient respiration. Two radiologists assessed the images for pleural adhesions based on motion findings. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were compared for each adhesion grade and patient group (patients with sufficient/insufficient respiration). Pearson's chi-squared test compared the group. Statistical significance was set at p<0.05. RESULTS: DCR correctly identified 22/25 patients with pleural adhesions, with 20 false-positive results (sensitivity, 88%; specificity, 83.5%; PPV, 52.4%; NPV, 97.12%). Although the diagnostic performances for the various adhesion grades were similar, specificity in patients with sufficient respiration increased to 93.9% (31/33), identifying all cases except for those with loose adhesions. CONCLUSIONS: DCR images revealed restricted and/or distorted motions in lung structures and structural tension in patients with pleural adhesions. DCR could be a useful technique for routine preoperative evaluation of pleural adhesions. Further development of computerised methods can assist in the quantitative assessment of abnormal motion findings.

Strange metal from a frustration-driven charge order instability.

Interparticle interactions are self-conflicting rather than cooperative on particular lattices. When such geometrical frustration occurs, charge ordering (CO) can be destabilized into non-trivial charge states such as the recently observed charge glass (CG). A more extreme case is the frustration-induced quantum melting of the CO that has been theoretically proposed. Here, we report d.c. charge transport and noise spectroscopy measurements for a triangular-lattice organic conductor situated close to the CO or CG. Our experiments demonstrate that these materials can host a strange metal with unusual charge dynamics, which we attribute to frustration-induced fluctuations of the CO or CG. Our results also show that the anomalous charge fluctuations can freeze into an insulating state when uniaxial stress is applied, which reduces the geometrical frustration. The present observations suggest the existence of the frustration-induced quantum melting of charges analogous to spin liquids.

Autophagy activators stimulate the removal of advanced glycation end products in human keratinocytes.

BACKGROUND: The accumulation of advanced glycation end products (AGEs) can impact cellular homoeostasis and protein structure, thus is implicated in numerous skin conditions including yellow, dull appearance. AGE formation is irreversible; thus, understanding of the recycling process of AGEs in the skin is critical for addressing skin appearance conditions. OBJECTIVE: To determine whether (i) accumulation of AGEs occurs in dull appearance group among young population (age 20-29) (ii) in vitro autophagy stimulation results in reduction of AGEs in keratinocytes. METHODS: Facial cheek biopsies were collected from Chinese women (age 20-50) exhibiting either dull or non-dull appearing skin. Histological assessment of glycation was performed for representative subjects among the 20-29 years sub-group by immunofluorescence staining of AGEs. LC-MS methods and keratinocyte cell culture were used to assess impact of autophagy modulators and skin care materials on carboxymethyl lysine (CML) amount, a representative AGE. RESULTS: Notable amounts of AGEs were observed in the epidermal samples among young females. Interestingly, the amount of AGEs was significantly higher among the dull skin appearance group. Treatment of keratinocytes with glyceraldehyde (GLA) enhanced CML in the cells, and postglycation treatment with autophagy activators reduced CML. Two skin care materials, Nymphaea alba flower extract (a.k.a. white water lily extract) and sucrose dilaurate, were identified based from in vitro autophagy activation and found to reduce CML in keratinocytes. CONCLUSION: We found AGEs accumulate in the facial epidermis even among young people, correlating to a yellow and dull appearance. We also demonstrated in vitro activation of autophagy can reduce AGEs in keratinocytes, and autophagy activating skin care materials, N. alba flower extract and sucrose dilaurate, also reduce AGEs in the keratinocyte in vitro model. These data suggest epidermal AGEs contribute to the dull skin appearance, and autophagy activators may provide an effective solution to improve dull appearance by removing and recycling the accumulated glycation in the skin.

Safer Vitrification of Mouse and Human Embryos Using the Novel Cryoroom Vitrification System for Assisted Reproductive Technology.

BACKGROUND: Vitrification is widely used for assisted reproductive technology (ART). Most vitrification devices require the skillful placement of embryos into the carrier and aspiration of excessive vitrification solution. OBJECTIVE: To evaluate the efficacy and safety of the Cryoroom as a vitrification device. MATERIALS AND METHODS: Mouse and human embryos were vitrified with Cryoroom or Cryotop, and the developmental potency was assessed in vitro. Mouse monozygotic twin blastocysts were vitrified with Cryoroom or Cryotop for microarray analysis. RESULTS AND DISCUSSION: In mouse and human embryos, there were no differences between the survival and developmental progress in each device. In silico, the Cryoroom device showed no changes, particularly in DNA methylation after vitrification compared with the Cryotop. These results showed that the form and function of the device may affect the gene expression levels in vitrified embryos. CONCLUSION: The Cryoroom represents a safe and potentially revolutionary vitrification device for ART.

Wnt3a signaling induces murine dental follicle cells to differentiate into cementoblastic/osteoblastic cells via an osterix-dependent pathway.

BACKGROUND AND OBJECTIVE: Dental follicle cells, putative progenitor cells for cementoblasts, osteoblasts and periodontal ligament cells, interplay with Hertwig's epithelial root sheath (HERS) cells during tooth root formation, in which HERS is considered to have an inductive role in initiating cementogenesis by epithelial-mesenchymal interaction. However, the specific mechanisms controlling the cementoblast/osteoblast differentiation of dental follicle cells are not fully understood. Canonical Wnt signaling has been implicated in increased bone formation by controlling mesenchymal stem cell or osteoblastic cell functions. This study examined the possible expression of canonical Wnt ligand in HERS and the role of Wnt signaling during the cementoblast/osteoblast differentiation of dental follicle cells. MATERIAL AND METHODS: The expression of Wnt3a, a representative canonical Wnt ligand, in HERS was assessed by immunohistochemistry. The differentiation and function of immortalized murine dental follicle cells were evaluated by measuring alkaline phosphatase (ALP, Alpl) activity and osteogenic gene expression. RESULTS: We identified the expression of Wnt3a in HERS during mouse tooth root development by immunohistochemistry as well as in cultured human epithelial rest cells of Malassez by real-time polymerase chain reaction, while no expression of Wnt3a was detected in cultured dental mesenchymal cells. Exposure of immortalized murine dental follicle cells to Wnt3a-induced ALP activity as well as expression of the Alpl gene. Pretreatment of cells with Dickkopf-1, a potent canonical Wnt antagonist, markedly attenuated the effect of Wnt3a on ALP expression. Furthermore, Wnt3a induced transcriptional activity of runt-related transcription factor 2 (Runx2) and expression of osterix at gene and/or protein levels. Treatment with osterix-small interfering RNA significantly inhibited Wnt3a-induced ALP expression at gene and protein levels. CONCLUSION: These findings suggest that HERS has a potential role in stimulating cementoblast/osteoblast differentiation of dental follicle cells via the Wnt/ß-catenin signaling pathway.

Anomalous connection of the left posterior renal vein with the left ascending lumbar vein in a Japanese cadaver.

A rare variation was found in one of the two left renal veins in a 94-year-old male cadaver undergoing routine dissection. The characteristic findings in the cadaver included, in addition to the primary left renal vein, the presence of a posterior left renal vein draining to the left ascending lumbar vein without communicating with the inferior vena cava and other renal veins. Variations in the number and arrangement of the vessels terminating in the renal veins are common, but to our knowledge, variation similar to our findings has not been previously reported. This variation may represent an immature form of the complicated development of the renal vessels.

Intensive Blood Pressure Management Preserves Functional Connectivity in Patients with Hypertension from the Systolic Blood Pressure Intervention Randomized Trial.

BACKGROUND AND PURPOSE: The Systolic Blood Pressure Intervention (SPRINT) randomized trial demonstrated that intensive blood pressure management resulted in slower progression of cerebral white matter hyperintensities, compared with standard therapy. We assessed longitudinal changes in brain functional connectivity to determine whether intensive treatment results in less decline in functional connectivity and how changes in brain functional connectivity relate to changes in brain structure. MATERIALS AND METHODS: Five hundred forty-eight participants completed longitudinal brain MR imaging, including resting-state fMRI, during a median follow-up of 3.84 years. Functional brain networks were identified using independent component analysis, and a mean connectivity score was calculated for each network. Longitudinal changes in mean connectivity score were compared between treatment groups using a 2-sample t test, followed by a voxelwise t test. In the full cohort, adjusted linear regression analysis was performed between changes in the mean connectivity score and changes in structural MR imaging metrics. RESULTS: Four hundred six participants had longitudinal imaging that passed quality control. The auditory-salience-language network demonstrated a significantly larger decline in the mean connectivity score in the standard treatment group relative to the intensive treatment group (P = .014), with regions of significant difference between treatment groups in the cingulate and right temporal/insular regions. There was no treatment group difference in other networks. Longitudinal changes in mean connectivity score of the default mode network but not the auditory-salience-language network demonstrated a significant correlation with longitudinal changes in white matter hyperintensities (P = .013). CONCLUSIONS: Intensive treatment was associated with preservation of functional connectivity of the auditory-salience-language network, while mean network connectivity in other networks was not significantly different between intensive and standard therapy. A longitudinal increase in the white matter hyperintensity burden is associated with a decline in mean connectivity of the default mode network.

Dandruff/seborrhoeic dermatitis is characterized by an inflammatory genomic signature and possible immune dysfunction: transcriptional analysis of the condition and treatment effects of zinc pyrithione.

BACKGROUND: Dandruff/seborrhoeic dermatitis is a common scalp condition that is characterized by flakes, pruritus and sometimes mild erythema. These symptoms reflect tissue level events that are poorly understood at the molecular level. OBJECTIVES: The purpose of this work was: (i) to compare gene expression profiles in subjects with dandruff vs. those of subjects without dandruff to determine the key physiological disruptions manifest in the condition; and (ii) to determine the effect on this profile of treatment with a shampoo containing potentiated zinc pyrithione (ZPT). METHODS: In study 1, scalp biopsies were taken from 16 normal subjects and from involved and uninvolved sites in 15 subjects with dandruff. In study 2, 30 subjects with dandruff were treated for 3 weeks with a commercial ZPT shampoo (n = 15) or a vehicle (n = 15), and scalp lesional biopsies were collected at baseline and end of study for transcriptomic analysis. RNA was extracted from all biopsies and Affymetrix gene chips were used to analyse transcriptomic profiles, followed by bioinformatic analysis. RESULTS: Analysis of study 1 biopsies revealed more than 7000 individual probes differentially regulated in dandruff lesional skin relative to normal. Enriched Gene Ontology categories included: lipid metabolism, immune response, response to stimulus, apoptosis, cell proliferation, and epidermal development. The most striking feature of lesional skin relative to normal was the reciprocal expression of induced inflammatory genes and repressed lipid metabolism genes. Induced inflammatory genes were also enriched in dandruff uninvolved skin, suggesting the existence of predisposing factors associated with inflammation. Many genes increased in lesional skin were increased at the level of protein in stratum corneum samples (e.g. IL-1RA, S100A8, S100A9, S100A11, IL-8). Under conditions known to improve overall scalp condition, the ZPT shampoo treatment in study 2 produced a transcriptomic profile resembling that of normal scalp skin. CONCLUSIONS: These data provide novel insights into the nature of dandruff and the therapeutic action of potentiated ZPT-containing shampoo, and provide a basis to explore many new mechanistic questions related to these topics.

What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women.

BACKGROUND: It has long been known that women lose satisfaction with their hair with ageing. Our data show that caucasian women perceive a decrease in hair amount in their mid 40s with a further decrease in the mid to late 50s, which leads to this dissatisfaction. Neither loss of density (hairs per cm(2) ) nor shaft diameter alone can fully account for this perception. A new metric, 'hair amount', is proposed as a quantitative metric combining the impact of both density and diameter on the perception of hair loss. OBJECTIVES: Creation of a single parameter combining the contribution of diameter and density to perception of female age-related hair loss. METHODS: In total, 1099 caucasian women (ages 18-66 years) with self-perceived hair loss and 315 caucasian women (ages 17-86 years) with no complaint of hair loss were evaluated. Scalp hair diameter was measured using optical fibre diameter and image analysis. Scalp hair density was measured by phototrichogram with manual or automated counting. RESULTS: Parietal scalp hair diameter increased from ages 20 to 40-45 years, then decreased. Hair density was highest in the youngest group, age 20-30 years, and decreased thereafter with increasing rate. In women self-perceiving hair loss, the rate of decrease in density was significantly faster than for women with no self-perception of hair loss. The combined metric 'hair amount' was relatively constant at younger ages, increasing very slightly to age 35 years, then decreasing significantly. CONCLUSIONS: Increasing hair shaft diameter offsets decreasing hair density through the mid 30s. After that, a lower rate of diameter increase combined with the decrease in density begins to significantly impact the perception of hair amount so that thinning becomes increasingly more noticeable in the mid 40s to the mid to late 50s. Quantitative determination of hair amount is a useful tool to combine the contributions of hair density and diameter to women's perception of age-related hair loss.

Tissue rinse liquid-based cytology: a feasible tool for the intraoperative pathological evaluation of sentinel lymph nodes in breast cancer patients.

OBJECTIVES: A unique diagnostic method was designed for the intraoperative pathological evaluation of sentinel lymph nodes (SLNs) in breast cancer patients, and the results were verified with 2 years of experience. METHODS: Excised lymph nodes were cut into 2-mm-thick slices and rinsed thoroughly in CytoRich Red(®). The sliced tissues were embedded in a paraffin block. Three cytological glass slides of the cells exfoliated in CytoRich Red(®) were prepared by the SurePath(®) liquid-based cytology (LBC) technique. Two slides were stained by the Papanicolaou method, and the remaining slide was immunostained with an anti-keratin antibody. This process is called tissue rinse liquid-based cytology (TRLBC). The results of TRLBC were compared with those of the final pathological diagnoses, including immunostaining with an anti-keratin antibody on paraffin blocks (PB). RESULTS: This study analysed 444 SLNs from 247 consecutive breast cancer patients. It required 35 minutes to complete the intraoperative diagnosis on a single node, and it took an additional 5 minutes per node if more than one node was submitted. When the results of PB were assumed to be the gold standard, the sensitivity and specificity of TRLBC were 81.9% and 96.1%, respectively. TRLBC detected all nodes with macrometastasis and 23 of 24 nodes with micrometastasis. Fifteen false-negative TRLBC results were 'isolated tumour cell clusters' on PB, but there was one with micrometastasis histologically. Four of 14 false-positive TRLBC results were proven to be true positive by supplementary examination using step sectioning of the paraffin blocks of the nodes. CONCLUSION: TRLBC is a feasible and promising intraoperative cytopathological tool showing a comparable efficacy to PB while still allowing the conventional postoperative histological examination.

Effects of tourism promotion on COVID-19 spread: The case of the "Go To Travel" campaign in Japan.

Introduction: On July 22, 2020, the Japanese government launched the "Go to Travel" campaign that subsidizes 50% of personal travel expenditure to support the tourism industry under the COVID-19 pandemic. This policy was controversial from the viewpoint of infection spread and was temporarily cancelled in December 2020, though there was no statistical evidence. Methods: This is the first study that measures the extent to which this campaign increased COVID-19 cases. This study regards the campaign as a natural experiment: although Tokyo and its commuting areas experienced the same time-series trends of COVID-19 cases before the "Go To Travel" campaign, this campaign was implemented in areas outside Tokyo, but not in Tokyo. Then, the comparison (difference-in-differences) yields the campaign's effect. Results: The estimation shows that the "Go To Travel" campaign significantly raised the increment rate of cases by 23.7%-34.4% during July 30-August 4. There is no significant effect after August 5. In addition, our simulation identified the number of campaign-related cases in each city. Conclusions: Although the campaign significantly spread COVID-19, the effect was not continuous to permanently change the time-series trend.

Development of a radiopaque tiltmeter to improve reproducibility for Fowler's position on chest radiography.

INTRODUCTION: We have developed a novel radiopaque tiltmeter (ROT) that can indicate patient tilt during a radiography examination and display it on X-ray images. This study evaluated the effect of variation of patient tilt on the reproducibility of Fowler's position for chest radiography and the accuracy of the ROT. METHODS: We evaluated the reproducibility of Fowler's position based on changes from the first day in the central venous catheter (CVC) tip position and the cardiothoracic ratio (CTR) with and without a digital tiltmeter to verify its efficacy in patients who underwent mobile chest radiography. The ROT contains radiopaque liquid consisting of white barium sulfate solution and oil and has a scale bar of 15°-75° with increments of 15° to indicate ROT tilt. The ROT tilt was increased from 10° to 80° in increments of 10°. We then evaluated (1) the difference between the ROT tilt and the tilt measured with a digital tiltmeter, and (2) the ROT tilt displayed on the X-ray image. RESULTS: With regard to reproducibility in Fowler's position, changes in the CVC tip position were 2.8 ± 3.9 mm and 10.7 ± 10.6 mm with and without the tiltmeter, respectively (p < 0.05) and the respective rates of change in the CTR were 0.7% ± 0.6% and 4.0% ± 2.1% (p < 0.05). Differences between the ROT tilt and the tilt measured by the digital tiltmeter were within ±2.5°. All ROT tilts displayed on the X-ray images were recognized exactly as each tilt. CONCLUSION: Our novel ROT had the potential to accurately indicate patient tilt during chest radiography, which could be helpful in terms of reproducibility and precise follow-up. IMPLICATIONS FOR PRACTICE: Use of the ROT for determination of patient tilt can improve reproducibility in Fowler's position, allowing more accurate serial X-ray imaging.

"Donut's shape" radiosurgical treatment planning for large cystic metastatic brain tumors.

BACKGROUND: Radiosurgical management of large cystic metastatic brain tumors represents a significant challenge. Nevertheless, modified dose planning has shown beneficial results in such cases. METHOD AND RESULTS: "Donut's shape" radiosurgical treatment planning is based on the chain-like application of multiple, small-sized isocenters for selective coverage of the contrast-enhancing tumor capsule and minimal irradiation of the central cystic area. Such an approach was used for the management of large cystic intracranial metastases, which were not accompanied by a significant mass effect and did not require immediate volume reduction. Treatment was done using Leksell Gamma Knife model C with automatic positioning system. The majority of treated lesions showed significant shrinkage after radiosurgery and no major complications were met. CONCLUSION: Large cystic metastatic brain tumors may be successfully treated with gamma knife radiosurgery alone using the proposed "donut's shape" dose planning with coverage of the contrast-enhancing tumor capsule by multiple small-sized isocenters.

Apple pectin affects the efficacy of epigallocatechin gallate on oral sucrose tolerance test in adult mice.

Epigallocatechin gallate (EGCg), a dietary polyphenol and a major tea catechin, is a known sucrase inhibitor. Since dietary pectin is known to modulate some of the functions of the gastrointestinal tract, we investigated whether it could specifically affect the efficacy of EGCg on an oral sucrose tolerance test in mice. Male Crj:CD-1 (ICR) mice (seven weeks old) were randomly divided into two groups and fed a 5 % apple pectin (PE) or 5 % cellulose (CE) diet (control diet) for 28 days. After the experimental diet period, all mice were fasted overnight. A volume of 0.2 mL EGCg (20 mg/mL) was orally administered to all the mice by stainless steel feeding needle via injection syringe and a sucrose tolerance test was performed. The blood glucose levels were measured in blood collected from the tail vein using the OneTouch® Ultra® blood glucose monitoring system. Blood glucose levels at 30 minutes and 60 minutes after sucrose loading in the PE group were significantly higher than initial blood glucose levels. However, blood glucose levels at 30 minutes, 60 minutes, and 120 minutes after sucrose loading in the CE group were not significantly higher than initial blood glucose levels. After laparotomy, plasma lipids were also measured. Plasma triglyceride concentrations were significantly greater in the PE group than in the CE (control) group. This demonstrates that dietary pectin can affect the efficacy of EGCg on the oral sucrose tolerance test in mice.

Abrogation of bronchial eosinophilic inflammation and airway hyperreactivity in signal transducers and activators of transcription (STAT)6-deficient mice.

Signal transducers and activators of transcription 6 (STAT6) is essential for interleukin 4-mediated responses, including class switching to IgE and induction of type 2 T helper cells. To investigate the role of STAT6 in allergic asthma in vivo, we developed a murine model of allergen-induced airway inflammation. Repeated exposure of actively immunized C57BL/6 mice to ovalbumin (OVA) aerosol increased the level of serum IgE, the number of eosinophils in bronchoalveolar lavage (BAL) fluid, and airway reactivity. Histological analysis revealed peribronchial inflammation with pulmonary eosinophilia in OVA-treated mice. In STAT6-deficient (STAT6-/-) C57BL/6 mice treated in the same fashion, there were no eosinophilia in BAL and significantly less peribronchial inflammation than in wild-type mice. Moreover STAT6-/- mice had much less airway reactivity than wild-type mice. These findings suggest that STAT6 plays a crucial role in the pathogenesis of allergen-induced airway inflammation.

Renoprotective effects of telmisartan in patients with advanced chronic kidney disease.

BACKGROUND: Angiotensin II receptor blockers (ARBs) provide renoprotective effects in patients with mild-to-moderate chronic kidney disease (CKD). However, there have been few reports regarding whether ARBs show clinical efficacy and safety in patients with advanced CKD. METHODS: Seventy-two hypertensive patients with Stages 3 - 4 CKD receiving no ARBs were enrolled in this study and observed up to 48 months. Telmisartan was added to conventional antihypertensive agents (n = 36, mean estimated glomerular filtration ratio [eGFR] 19.7 ml/min/1.73 m2) whilst the remaining control patients were not treated with ARBs (n = 36, mean eGFR 19.2 ml/min/1.73 m2). Urinary protein excretion, kidney function, and the occurrence of end-stage renal disease requiring renal replacement therapy, hyperkalemia, and death were analyzed. RESULTS: Baseline characteristics of each group were similar. During the observation period, the blood pressures of each group decreased at similar rates. In the telmisartan group, 17 patients (47.2%) were introduced to renal replacement therapy, as compared with 31 patients (86.1%) in the control group (relative risk 0.55, 95% confidence interval 0.19 - 0.92, p < 0.05). Telmisartan significantly reduced proteinuria levels (from 3.47 +/- 3.00 to 2.41 +/- 2.46 g/g . creatinine, p < 0.05) and was associated with a reduction of 49.6% in the decline rate of eGFR. The incidence of major adverse events in both groups was similar. CONCLUSIONS: The addition of telmisartan to conventional antihypertensive therapy is associated with significant improvement in kidney outcome without increased incidence of adverse effects, even in patients with advanced CKD.

The elderly patients on hemodialysis.

Nephrologists care for an increasing number of elderly patients on hemodialysis. As such, an understanding of the overlap among complications of hemodialysis and geriatric syndromes is crucial. This article reviews hemodialysis management issues including vascular access, hypertension, anemia and bone and mineral disorders with an attention towards the distinct medical needs of the elderly. Key concepts of geriatrics frailty, dementia and palliative care are also discussed, as nephrologists frequently participate in decision-making directed toward balancing longevity, functional status and the burden of therapy.

[Primary anterior mediastinal huge lipoma: report of a case].

We report a case of anterior mediastinal lipoma. A 71-year-old female was admitted for cough. A fat density tumor from anterior mediastinum to left thoracic cavity was found by chest X-ray, chest computed tomography (CT) and magnetic resonance imaging (MRI). Defect of left dorsal diaphragm was suspected and there was a possibility that the tumor was connected to retroperitoneum. Under the preoperative diagnosis of a benign huge mediastinal lipoma, we conducted an operation. At 1st, we observed by thoracoscopy and made sure that the mass was primary anterior mediastinal tumor and not connected to retroperitoneum. Through the median sternotomy, we completely resected the tumor with thymus. The tumor showed 27 cm in diameter, and histopathological diagnosis of the tumor was benign lipoma. Lipoma of the mediastinum is very rare and about 0.3% of all mediastinal tumors. It is sometimes difficult to distinguish huge lipoma from liposarcoma only by clinical examinations such as CT scan or MRI. We evaluated the condition of the tumor by thoracoscopic observation, and the tumor was safely and completely resected by median sternotomy.

Control system for the new RIKEN 28-GHz superconducting electron cyclotron resonance ion source for SRILAC.

A new RIKEN 28-GHz superconducting electron cyclotron resonance ion source (SC-ECRIS) has been installed for the superconducting RIKEN linear accelerator (SRILAC). The new SC-ECRIS control system mainly consists of programmable logic controllers (PLCs) embedded with the Experimental Physics and Industrial Control System. To improve the reliability as compared with previous control systems, two types of PLC central processing units, sequential and Linux, have been installed in the same unit. Past experience has shown that new types of designs that can rapidly respond to system scalability are key. By connecting PLC stations using star-topology field buses, their rapid and cost-effective response to system changes is realized for the new devices. Furthermore, a unique data acquisition system employing a 920-MHz-band radio was developed to measure analog data such as the temperature at the high-voltage stage.
