An analysis on the two-phase flow in a helical wire inserted tube using commercial CFD code, CFX11.0, was performed in bubbly flow and annular flow regions. The analysis method was validated with the experimental results of Takeshima. Bubbly and annular flows in a 10 mm inner diameter tube with varying pitch lengths and inserted wire diameters were simulated using the same analysis methods after validation. The geometry range of p/D was 1-4 and e/D was 0.08-0.12. The results show that the inserted wire with a larger diameter increased swirl flow generation. An increasing swirl flow was seen as the pitch length increased. Regarding pressure loss, smaller pitch lengths and inserted wires with larger diameters resulted in larger pressure loss. The average liquid film thickness increased as the pitch length and the diameter of the inserted wire increased in the annular flow region. Both in the bubbly flow and annular flow regions, the effect of pitch length on swirl flow generation and pressure loss was more significant than that of the inserted wire diameters. Pitch length is a more dominant factor than inserted wire diameter for the design of the swirl flow generator in small diameter tubes.

We report the clinical outcomes of a female patient with severe AN, whose chest had become deformed due to thoracic fracture. Lumbar BMD was 0.358 g/cm2 (T-score = −6.3, and total hip BMD was 0.411 g/cm2 (T-score = −4.4. Active vitamin D increased these parameters by 81.0% and 57.4%, respectively, but a drop in her nutrition status afterward resulted in a sharp decrease in BMD values. These findings suggest that adequate nutrient intake is essential for effective osteoporosis treatment in patients with AN.

No definitive data are available to determine which drug should be administered first during salvage-line treatment. Therefore, it is imperative that we establish the sequence of administration by considering drug toxicity profiles based on patient characteristics, such as age, performance status, comorbidities, tolerability to previous treatments, and patient preferences. The identification of predictive biomarkers in response to TAS-102 or its toxicity is urgently needed for better patient selection. Moreover, to strengthen efficacy or relieve toxicity, combinations with other agents, which could potentially emerge as standard treatment regimens, have been investigated and compared to existing active regimens for mCRC.

Since the 1960s, Kawasaki City has been leading the nation in its efforts regarding community mental health practices. Public institutions such as the Psychiatric Rehabilitation Center in the central area of the city and the Mental Health and Welfare Center in the southern area have mainly developed the psychiatric rehabilitation system. However, since 2000, new mental health needs have emerged, as the target of mental health and welfare services has been diversified to include people with developmental disorders, higher brain dysfunction, or social withdrawal, in addition to those with schizophrenia. Therefore, Kawasaki City's plan for community-based rehabilitation was drawn up, which makes professional support available for individuals with physical, intellectual, and mental disabilities. As the plan was being implemented, in 2008, the Northern Community Rehabilitation Center was established by both the public and private sectors in partnership. After the community mental health teams were assigned to both southern and northern areas of the city, the community partnership has been developed not only for individual support but also for other objectives that required the partnership. Takeshima pointed out that the local community should be inclusive of the psychiatric care in the final stage of community mental health care in Japan. Because of the major policies regarding people with disabilities, the final stage has been reached in the northern area of Kawasaki City. This also leads to improvement in measures for major issues in psychiatry, such as suicide prevention and intervention in psychiatric disease at an early stage.

As an anaplastic lymphoma kinase (ALK gene translocation was identified, the therapy was changed to crizotinib. However, the patient’s blood creatinine level increased, and her physical status worsened. Alectinib also induced exacerbation of renal dysfunction but was controlled by dose reduction of 140 mg twice daily for 2 weeks treatment and 2 weeks break were repeated, and exhibited a partial response for 16 months. Here, we describe the case in which alectinib treatment had beneficial clinical effects on ALK-positive lung adenocarcinoma, which controlled the adverse renal effects by dose reduction and drug breaks.

Acute lung injury (ALI recurred 31 days after the first ALI episode. Both ALI episodes occurred 48 hours after transfusion. Laboratory examinations revealed the presence of various antileukocyte antibodies including antiplatelet antibody in the recipient's serum but not in the donors' serum. The authors speculate that antiplatelet antibodies can have an inhibitory effect in the recipient, which can modulate the bona fide procedure of ALI and lead to a delay in the onset of ALI. This case illustrates the crucial role of a recipient's platelets in the development of TRALI.Keywords: delayed TRALI syndrome, recurrence, anti-platelet antibody

Methods: The subjects were 37 febrile patients with urinary tract infection in whom we examined the serum procalcitonin concentration at the start of treatment. Results: Thirty patients had acute pyelonephritis (16 simple, 14 complex, one had emphysematous pyelonephritis, five had acute prostatitis, and one had acute epididymitis. The procalcitonin level was <0.5 ng/mL in 18 patients, ≥0.5 ng/mL in one patient, ≥2 ng/mL in seven patients, and ≥10 ng/mL in 11 patients. Five of the 11 patients with procalcitonin levels ≥ 10 ng/mL had disseminated intravascular coagulation. All patients with urinary tract obstruction and disseminated intravascular coagulation had procalcitonin levels ≥ 10 ng/mL. Conclusion: Although this retrospective study comprised a small number of patients, we found that procalcitonin was a useful marker for urinary tract infection.

A 69-year-old woman was referred to our hospital because of abdominal fullness. Colonoscopy could be performed only up to the hepatic flexure due to an elongated colon and residual stools. Because her symptoms improved, upper GI endoscopy was performed 11 days later. The patient developed severe abdominal pain two hours after the examination. Abdominal X-ray and computed tomography showed massive free air. Immediate laparotomy was performed for the intestinal perforation. After removal of stool, a perforation site was detected in the cecum with an invasive ascending colon cancer. Therefore, a right hemicolectomy, ileostomy, and transverse colostomy were performed. Although she developed postoperative septicemia, the patient was discharged 38 days after admission. Seven months postoperatively, the patient died of lung, liver, and brain metastases. Even in cases with a lesion that is not completely obstructed, it is important to note that air insufflations during upper GI endoscopy can perforate the intestinal wall in patients with advanced colon cancer.Keywords: colonic perforation, colon cancer, upper gastrointestinal endoscopy, fecal peritonitis

Aspergillus oryzae AoSO is a novel component of stress granules upon heat stress in filamentous fungi.

Directory of Open Access Journals (Sweden)

Hsiang-Ting Huang

Full Text Available Stress granules are a type of cytoplasmic messenger ribonucleoprotein (mRNP granule formed in response to the inhibition of translation initiation, which typically occurs when cells are exposed to stress. Stress granules are conserved in eukaryotes; however, in filamentous fungi, including Aspergillus oryzae, stress granules have not yet been defined. For this reason, here we investigated the formation and localization of stress granules in A. oryzae cells exposed to various stresses using an EGFP fusion protein of AoPab1, a homolog of Saccharomyces cerevisiae Pab1p, as a stress granule marker. Localization analysis showed that AoPab1 was evenly distributed throughout the cytoplasm under normal growth conditions, and accumulated as cytoplasmic foci mainly at the hyphal tip in response to stress. AoSO, a homolog of Neurospora crassa SO, which is necessary for hyphal fusion, colocalized with stress granules in cells exposed to heat stress. The formation of cytoplasmic foci of AoSO was blocked by treatment with cycloheximide, a known inhibitor of stress granule formation. Deletion of the Aoso gene had effects on the formation and localization of stress granules in response to heat stress. Our results suggest that AoSO is a novel component of stress granules specific to filamentous fungi. The authors would specially like to thank Hiroyuki Nakano and Kei Saeki for generously providing experimental and insightful opinions.

The CADi consists of items involving immediate recognition memory for three words, semantic memory, categorization of six objects, subtraction, backward repetition of digits, cube rotation, pyramid rotation, trail making A, trail making B, and delayed recognition memory for three words. The present study examined the reliability and validity of the CADi. Methods: CADi evaluations were conducted for patients with dementia, healthy subjects selected from a brain checkup system, and community-dwelling elderly people participating in health checkups. Results: CADi scores were lower for dementia patients than for healthy elderly individuals and correlated significantly with Mini-Mental State Examination scores. Cronbach’s alpha values for the CADi were acceptable (over 0.7, and test–retest reliability was confirmed via a significant correlation between scores separated by a one-year interval. Conclusion: These results suggest that the CADi is a useful tool for mass screening of dementia in Japanese populations. Keywords: dementia, mass screening, early detection, iPad

Full Text Available Sho Nakamura, Tadahisa Fukui, Shuhei Suzuki, Hiroyuki Takeda, Kaname Watanabe, Takashi Yoshioka Department of Clinical Oncology, Yamagata University Faculty of Medicine, Yamagata, Japan Abstract: Bone marrow metastasis is a rare consequence of colorectal cancer that results in a poor prognosis; few reports describe a favorable response to doublet chemotherapy combined with targeted therapy, which is currently the standard treatment. We experienced a case where anti-epidermal growth factor receptor (EGFR antibody produced a marked anti-tumor response to bone marrow metastasis that led to long-term survival. A 51-year-old man was diagnosed with a primary KRAS-wildtype rectal cancer with multiple metastases, including the bone marrow. Disease control was achieved for 10.8 months following chemotherapy with a modified FOLFOX6 regimen combined with an anti-EGFR antibody. He died of cancer 22.7 and 16.6 months after disease onset and first-line chemotherapy, respectively. This case shows that early tumor shrinkage and deepness of response to the anti-EGFR antibody were observed even in a patient with bone marrow metastasis. Anti-EGFR antibody therapy should therefore be considered even when a patient’s medical condition appears to be poor owing to bone marrow metastasis. Moreover, tumors that are likely to be sensitive to chemotherapy, such as RAS-wildtype colorectal cancers, can be considered for anti-EGFR antibody therapy even if the patient is considered unfit for chemotherapy.

Full Text Available Katsutoshi Miura,1 Hiroyuki Mineta2 1Department of Health Science, Pathology, and Anatomy, 2Department of Otorhinolaryngology, Hamamatsu University School of Medicine, Hamamatsu, Japan Purpose: A scanning acoustic microscope (SAM uses an ultrasound to image an object by plotting the speed-of-sound (SOS through tissues on screen. Because hard tissues result in great SOS, SAM can provide data on the tissue elasticity. This paper investigated the utility of SAM in evaluating thyroid lesions. Methods: Formalin-fixed, paraffin sections were scanned with a 120 MHz transducer. SOS through each area was calculated and plotted on the screen to provide histological images, and SOS of each lesion was compared and statistically analyzed. Results: High-concentrated colloids, red blood cells, and collagen fibers showed great SOS, while low-concentrated colloids, parathyroids, lymph follicles, and epithelial tissues including carcinomas demonstrated lower SOS. SAM clearly discriminated structure of thyroid components corresponding to low magnification of light microscopy. Thyroid tumors were classified into three groups by average SOS: the fast group consisted of follicular adenomas/carcinomas and malignant lymphomas; the slow group contained poorly differentiated/undifferentiated carcinomas; and the intermediate group comprised papillary/medullary carcinomas. Fragmented colloids, irregular-shaped follicles, and desmoplastic reactions were observed in the invasive area of surrounding carcinomas. Conclusion: The SAM imaging method had the following benefits: 1 precise images were acquired in a few minutes without special staining; 2 structural irregularity and desmoplastic reactions, which indicated malignancy, were detected; 3 images reflected tissue elasticity, which was statistically comparable among lesions by SOS; 4 follicular functional activity was predictable by converting colloid concentration to SOS; and 5 tumor classification was predictable by SOS

The chronological changes in various factors, including patient’s age, sex, histological type, tumor size, pathological stage (p-stage, surgical method, operative time, intraoperative blood loss, 30-day mortality, and postoperative overall survival (OS, were evaluated.Results: A total of 1,616 patients were included. The numbers of resected patients, females, adenocarcinomas, p-stage IA patients, and age at the time of surgery increased with time, but tumor size decreased (all P<0.0001. Concerning surgical methods, the number of sublobar resections increased, but that of pneumonectomies decreased (P<0.0001. The mean operative time, intraoperative blood loss, and the postoperative 30-day mortality rate decreased (all P<0.0001. When the patients were divided into two groups (1974–2004 and 2005–2014, the 5-year OS rates for all patients and for p-stage IA patients improved from 44% to 79% and from 73% to 89%, respectively (all P<0.0001. The best 5-year OS rate was obtained for sublobar resection (73%, followed by lobectomy (60%, combined resection (22%, and pneumonectomy (21%; P<0.0001.Conclusion: Changes in epidemiological factors, a trend toward less invasive surgery, and a remarkably improved postoperative OS were confirmed, which demonstrated the increasingly important role of surgery in therapeutic strategies for lung cancer.

An amine-terminated polyamidoamine dendrimer (PD, an unmodified plain type of PD, has the obvious disadvantage of cytotoxicity, but still serves as an attractive molecule because it easily adheres to the cell surface, facilitating easy cellular uptake. Single-photon emission computed tomographic imaging of a mouse following intravenous injection of a radiolabeled PD failed to reveal any signal in the intracranial region. Furthermore, examination of the permeability of PD particles across the blood–brain barrier (BBB in vitro using a commercially available kit revealed poor permeability of the nanoparticles, which was suppressed by an inhibitor of caveolae-mediated endocytosis, but not by an inhibitor of macropinocytosis. Physicochemical analysis of the PD revealed that cationic PDs are likely to aggregate promptly upon mixing with body fluids and that this prompt aggregation is probably driven by non-Derjaguin–Landau–Verwey–Overbeek attractive forces originating from the surrounding divalent ions. Atomic force microscopy observation of a freshly cleaved mica plate soaked in dendrimer suspension (culture media confirmed prompt aggregation. Our study revealed poor transfer of intravenously administered cationic PDs into the intracranial nervous tissue, and the results of our analysis

The purpose of this study was to examine the association between cognitive function at baseline and change in physical performance after exercise intervention in older adults with mild cognitive impairment.Methods: Forty-four older adults diagnosed with mild cognitive impairment based on the Peterson criteria (mean age 74.8 years consented to and completed a 6-month twice weekly exercise intervention. The Timed Up and Go (TUG test was used as a measure of physical performance. The Mini-Mental State Examination (MMSE, Trail Making Test Part B, Geriatric Depression Scale, baseline muscle strength of knee extension, and attendance rate of intervention, were measured as factors for predicting trainability.Results: In the correlation analysis, the change in TUG showed modest correlations with attendance rate in the exercise program (r = -0.354, P = 0.027 and MMSE at baseline (r = -0.321, P = 0.034.

Thus, development of a curative treatment and strategies for early diagnosis and treatment are urgently needed. Pathological analysis of renal biopsy is the gold standard for the diagnosis and assessment of disease activity; however, immediate and frequent assessment based on biopsy specimens is difficult. Therefore, a simple and safe alternative is desirable. On the other hand, it is now widely accepted that multi-hit steps, including production of aberrantly glycosylated serum IgA1 (first hit, and IgG or IgA autoantibodies that recognize glycan containing epitopes on glycosylated serum IgA1 (second hit and their subsequent immune complex formation (third hit and glomerular deposition (fourth hit, are required for continued progression of IgAN. Although the prognostic and predictive values of several markers have been discussed elsewhere, we recently developed a highly sensitive and specific diagnostic method by measuring serum levels of glycosylated serum IgA1 and related IgA immune complex. In addition, we confirmed a significant correlation between serum levels of these essential effector molecules and disease activity after treatment, suggesting that each can be considered as a practical surrogate marker of therapeutic effects in this slowly progressive disease. Such a noninvasive diagnostic and activity assessment method using these disease-oriented specific biomarkers may be useful in the early diagnosis of and intervention in IgAN, with

Methods: Twenty-four eyes of 24 patients with treatment-naive ME from BRVO were treated with intravitreal injections of anti-VEGF agents. Recurred ME was treated with pars plana vitrectomy combined with internal limiting membrane peeling. Results: After the surgery, ME was significantly reduced at 1 month (P=0.031 and the reduction increased with time (P=0.007 at the final visit. With the reduction in ME, treated eyes showed a slow improvement in visual acuity (VA. At the final visit, improvement in VA was statistically significant compared with baseline (P=0.048. The initial presence of cystoid spaces, serous retinal detachment, or subretinal hemorrhage under the fovea, as well as retinal perfusion status, showed no association with VA improvement. However, the presence of epiretinal membrane showed a significant association with the visual recovery. Although eyes without epiretinal membrane showed visual improvement (-0.10±0.32 in logarithm of the minimum angle of resolution [logMAR], eyes with epiretinal membrane showed greater visual improvement (-0.38±0.12 in logMAR, P=0.012. Conclusion: For recurrent ME due to BRVO after anti-VEGF treatment, particularly when accompanied by epiretinal membrane, pars plana vitrectomy combined with internal limiting membrane peeling might be a

Efficient gene transfer into MSCs is essential not only for basic research in developmental biology but also for therapeutic applications involving gene-modification in regenerative medicine. Adenovirus vectors (Advs can efficiently and transiently introduce an exogenous gene into many cell types via their primary receptors, the coxsackievirus and adenovirus receptors, but not into MSCs, which are deficient in coxsackievirus and adenovirus receptors expression. To overcome this problem, we developed an Adv coated with a spermine-pullulan (SP cationic polymer and investigated its physicochemical properties and internalization mechanisms. We demonstrated that the SP

The development of tumor-targeting systems may improve treatment outcomes. Nanomedicine platforms are of particular interest for enhancing chemotherapeutic efficiency, and they include polymeric micelles, which enable targeting of multiple drugs to solid tumors, including imaging and therapeutic agents. This allows concurrent diagnosis, targeting strategy validation, and efficacy assessment. We used polymeric micelles containing the T1-weighted magnetic resonance imaging contrast agent gadolinium-diethylenetriaminpentaacetic acid (Gd-DTPA and the parent complex of the anticancer drug oxaliplatin [(1,2-diaminocyclohexaneplatinum(II (DACHPt] for simultaneous imaging and therapy in an orthotopic rat model of HCC. The Gd-DTPA/DACHPt-loaded micelles were injected into the hepatic artery, and magnetic resonance imaging performance and antitumor activity against HCC, as well as adverse drug reactions were assessed. After a single administration, the micelles achieved strong and specific tumor contrast enhancement, induced high levels of tumor apoptosis, and significantly suppressed tumor size and growth. Moreover, the micelles did not induce severe adverse reactions and significantly improved survival outcomes in comparison to oxaliplatin or

However, whether the presence of a disease influences these effects is unclear. This study aimed to clarify the difference in the effects of disclosing genetic testing results of the risk for developing salt-sensitive hypertension on the behavioral modifications with respect to salt intake in hypertensive and nonhypertensive patients.Methods: A cross-sectional study using a self-administered questionnaire was conducted for outpatients aged >20 years (N=2,237 at six primary care clinics and hospitals in Japan. The main factors assessed were medical histories of hypertension, salt preferences, reduced salt intakes, and behavior modifications for reducing salt intake. Behavioral modifications of participants were assessed using their behavior stages before and after disclosure of the hypothetical genetic testing results. Results: Of the 2,237 participants, 1,644 (73.5% responded to the survey. Of these respondents, 558 (33.9% patients were hypertensive and 1,086 (66.1% were nonhypertensive. After being notified of the result “If with genetic risk”, the nonhypertensive participants were more likely to make positive behavioral modifications compared to the hypertensive patients among all participants and in those aged <65 years (adjusted relative ratio [ad-RR], 1.76; 95% confidence interval, 1.12−2.76 and ad-RR, 1

However, optimization of the release rate in polymeric micellar nanoscale drug delivery systems has not been fully investigated. In this study NC-6301, a poly(ethylene glycol-poly(aspartate block copolymer with docetaxel (DTX covalently bound via ester link, was synthesized with various numbers of DTX molecules bound to the polymer backbone. The number of DTX molecules was determined up to 14 to achieve an optimal release rate, based upon the authors' own pharmacokinetic model using known patient data. Efficacy and toxicity of the formulation was then tested in animals. When administered three times at 4-day intervals, the maximum tolerated doses of NC-6301 and native DTX were 50 and 10 mg/kg, respectively, in nude mice. Tissue distribution studies of NC-6301 in mice at 50 mg/kg revealed prolonged release of free DTX in the tumor for at least 120 hours, thus supporting its effectiveness. Furthermore, in cynomolgus monkeys, NC-6301 at 6 mg/kg three times at 2-week intervals showed marginal toxicity, whereas native DTX, at 3 mg/kg with the same schedule, induced significant decrease of food consumption and neutrophil count. NC-6301 at 50 mg/kg in mice also regressed a xenografted tumor of MDA-MB-231 human breast cancer. Native DTX, on the other hand, produced only transient and slight regression of the same tumor xenograft. NC-6301 also significantly inhibited growth of OCUM-2MLN human scirrhous gastric carcinoma in an orthotopic mouse

Three types of MWCNTs – VGCF®-X, VGCF®-S, and VGCF® (vapor grown carbon fibers; with diameters of 15, 80, and 150 nm, respectively – and three CSCNTs of different lengths (CS-L, 20–80 µm; CS-S, 0.5–20 µm; and CS-M, of intermediate length were tested. Human bronchial epithelial (BEAS-2B and malignant pleural mesothelioma cells were exposed to the CNTs (1–50 µg/mL, and cell viability, permeability, uptake, total reactive oxygen species/superoxide production, and intracellular acidity were measured. CSCNTs were less toxic than MWCNTs in both cell types over a 24-hour exposure period. The cytotoxicity of endocytosed MWCNTs varied according to cell type/size, while that of CSCNTs depended on tube length irrespective of cell type. CNT diameter and length influenced cell aggregation and injury extent. Intracellular acidity increased independently of lysosomal activity along with the number of vacuoles in BEAS-2B cells exposed for 24 hours to either CNT

Duloxetine is clinically effective in major depressive disorder and several chronic pain states, including CLBP. The objective of this post hoc meta-analysis was to assess direct and indirect analgesic efficacy of duloxetine for patients with CLBP in previous clinical trials. Methods: Post hoc path analyses were conducted of 3 randomized, double-blind, clinical studies of patients receiving duloxetine or placebo for CLBP. The primary outcome measure for pain was the Brief Pain Inventory, average pain score. A secondary outcome measure, the Beck Depression Inventory-II, was used for depressive symptoms. The changes in score from baseline to endpoint were determined for each index. Path analyses were employed to calculate the proportion of analgesia that may be attributed to a direct effect of duloxetine on pain.Results: A total of 851 patients (400 duloxetine and 451 placebo were included in this analysis. Duloxetine significantly improved pain scores compared with placebo (p<0.001. It also significantly improved depressive scores compared with placebo (p=0.015. Path analyses showed that 91.1% of the analgesic effect of duloxetine could be attributed to a direct analgesic effect, and 8.9% to its antidepressant effect. Similar results were obtained when data were evaluated at weeks 4 and 7, and when

There was no significant difference in the 3-year recurrence-free survival rate between patients with M and WT (6.3% vs 7.7%, P=0.656, and the patients with EGFR M had a significantly better 3-year PRS than those with WT (77.4% vs 51.7%, P=0.033. The 3-year PRS rate for patients with M/pathologic stage (p-stage I–II (87.5% was better than that for patients with M/p-stage III (60.0%, WT/p-stage I–II (52.7%, and WT/p-stage III (43.8%. There was a significant difference between patients with M/p-stage I and WT/p-stage I–II or WT/p-stage III (P=0.021 and 0.030, respectively. During the study period, of the 16 patients with mutants, 12 patients (75% received EGFR-tyrosine kinase inhibitor (TKI therapy and among the 40 patients with WT, no patient received

We investigated the ­sex-specific impact of early-life adversity on chronic pain, chronic multisite pain, and somatizing tendency with chronic pain. Methods: We examined 4229 respondents aged 20–79 years who participated in the Pain Associated Cross-Sectional Epidemiological Survey in Japan. Outcomes were: 1 chronic pain prevalence, 2 multisite pain (≥3 sites prevalence, and 3 multiple somatic symptoms (≥3 symptoms among respondents with chronic pain related to the presence or absence of early-life adversity. Multivariable-adjusted odds ratios (ORs were calculated with 95% confidence intervals using a logistic regression model including age, smoking status, exercise routine, sleep time, body mass index, household expenditure, and the full distribution of scores on the Mental Health Inventory-5. We further adjusted for pain intensity when we analyzed the data for respondents with chronic pain. Results: The prevalence of chronic pain was higher among respondents reporting the presence of early-life adversity compared with those reporting its absence, with multivariable ORs of 1.62 (1.22–2.15, p<0.01 in men and 1.47 (1.13–1.90, p<0.01 in women.

Upper abdominal symptoms, suggesting gastroesophageal reflux disease (GERD or functional dyspepsia, occur also in these patients. However, the relationship between these symptoms, concomitant with asthma, and the intensity of eosinophilic airway inflammation remains obscure. Objective: To assess the symptoms of asthma and rhinosinusitis, and to examine the relationship between the symptoms and bronchial inflammation, a new questionnaire, the G scale, was developed. To investigate the effects of GERD, dyspepsia, and rhinosinusitis on asthma symptoms and bronchial inflammation, the symptoms of asthma and rhinosinusitis obtained by the G scale, upper abdominal symptoms obtained by the modified F scale, a questionnaire for GERD and dyspepsia, and fractional exhaled nitric oxide (FeNO were analyzed. Methods: A prospective, observational study was performed in four hospitals in Gunma prefecture, and a retrospective analysis was done using data obtained from five hospitals in Gunma prefecture and Fukui prefecture, Japan. A total of 252 patients diagnosed as having asthma participated in the prospective study. Results: The frequency of daytime phlegm or losing the sense of smell had a positive correlation with FeNO levels in asthmatic

So far, only obesity and quadriceps weakness are identified as modifiable risk factors for knee OA. Core muscle strengthening is becoming increasingly popular among older adults because of its ability to enhance the activities of daily living during old age. This study investigated the associations of the size and quality of the abdominal trunk muscles with radiographic knee osteoarthritis (RKOA. Methods: From 2012 to 2016, data were collected from 146 males and 135 females (age 63.9±13.4 years, BMI 23.2±3.8 kg/m2 at annual musculoskeletal examinations, including knee radiographs and body composition analyses, by dual-energy X-ray absorptiometry. Cross-sectional areas of abdominal trunk muscles were measured using a single-slice computed tomography scan image obtained at the level of the umbilicus. Results: The prevalence of RKOA was 21.2% in males and 28.1% in females. Compared to subjects without RKOA, subjects with RKOA were ~6 years older and had smaller paraspinal muscle (38.4±8.7 vs 33.1±10.1 cm2, p<0.01 in males; 24.1±7.1 vs 20.7±7.5 cm2, p<0.05 in females. In contrast, there was no decrease in appendicular or total lean mass, and only in females, BMI and total fat mass (FM were higher in subjects with RKOA (21.5±3.5 vs 24.5±4.4 kg/m2, 16.7±7.0 vs 20.5±7.7 kg, respectively, both p<0.01. After adjusting for age and sex, smaller cross-sectional area/lower attenuation value of the paraspinal muscles was associated with RKOA (both p<0.05, while greater

In order to improve adherence by providing information about AD and the significance of pharmacotherapy, the Donepezil Outpatient Consultation Service (DOCS was set up. The influence of this service on medication persistence was assessed in the present study.Methods: Among outpatients starting donepezil therapy, we enrolled 59 patients between April 2008 and September 2010 before establishment of the DOCS (non-DOCS group and 52 patients between October 2010 and March 2012 who attended the DOCS (DOCS group. Each patient's and their caregiver's understanding about the clinical features of AD and pharmacotherapy with donepezil were also assessed. Their understanding was compared before and after the DOCS, and the 1-year medication persistence rate and the reasons for discontinuation were also investigated.Results: The 1-year medication persistence rate was significantly higher in the DOCS group than in the non-DOCS group (73

Nonetheless, recent studies have shown additional beneficial effects against obesity-related health risks, independent of AF reduction. Therefore it is important to determine whether AF plays a causal role in promoting metabolic disorders or is simply a symptom of increased obesity-related health risk factors. Clarification of the primary role of AF in the pathogenesis of obesity-related disease is also important.Objective: This retrospective study was conducted with the objectives of 1 comparison between groups exhibiting equivalent amounts of AF loss that resulted from distinct treatments (exercise and dietary restriction with respect to degrees of improvement in obesity-related health risk factors and 2 determination of definite differences in the outcomes of obesity-related health risk in subjects receiving identical treatment (exercise but exhibiting a remarkable difference in AF reduction.Design: In 66 subjects who completed a 12-week exercise or dietary restriction program, 17 parameters (systolic blood pressure [SBP] and diastolic blood pressure [DBP]; high-sensitivity C-reactive protein [hs-CRP]; leptin, adiponectin, tumor necrosis factor [TNF]-α, interleukin [IL]-6; alanine aminotransferase [ALT], gamma glutamyl transpeptidase [γGT]; lipid profile: high-density lipoprotein cholesterol [HDLC], triglyceride [TG

Measuring this important parameter is a challenge since the accuracy is frustrated by convections and imprecise non-contact temperature measurements, resulting in a wide variation of values reported in the literature so far. By improving the non-contact temperature measurement on a magnetically levitated drop of silicon the authors succeeded in a substantial reduction of the uncertainty in the measured values of the heat capacity and the thermal conductivity including their temperature dependence. Modulation of the heat power and an accurate measurement of the amplitude and phase of the resulting temperature variation constitute the major contribution to a higher accuracy. In their winning paper [4] the authors present a clear overview of their measurement setup and the experimental procedure and conditions, and give an extensive analysis of the parameters that play a part in the overall uncertainty. Measured values are compared with those obtained by other methods and reported in relevant literature. Moreover, the improvements of the instrumentation implemented by the authors contribute to a better understanding of the heat transport processes in liquid silicon. The four chairmen would like to thank the authors for choosing to publish their work in Measurement Science and Technology, and hope that other
