Abstract
Abstract
Introduction
Right ventricular free wall longitudinal strain (RVFWLS) is a sensitive tool for right ventricular (RV) function assessment. Furthermore, it shows incremental prognostic role in various cardiac diseases. RV involvement is frequently observed along with left ventricular (LV) involvement in cardiac sarcoidosis (CS) patients, while its impact on outcome is unclear.
Purpose
The aim of this study is to investigate the association between RV dysfunction detected by RVFWLS and cardiovascular event in patients with CS.
Methods
We retrospectively evaluated 51 patients with CS who were treated with prednisone from 2012 through 2020. Diagnosis of CS was made according to the Japanese Circulation Society diagnostic criteria. We evaluated RVFWLS at baseline using vender-independent software. We considered major adverse cardiovascular event (MACE: ventricular arrhythmia, heart failure hospitalization) to be the primary outcome.
Results
Mean age of the study population was 63±11 years, and 61% were female. At baseline, 25 patients (49%) had reduced left ventricular (LV) ejection fraction (EF) (<50%) and 18 patients (35%) had impaired RVFWLS (<17%). Patients with impaired RVFWLS showed lower LVEF% (42±12% vs. 53±13%, P=0.005) and larger LV end-systolic volume index (54±33 vs. 37±23ml/m2, P=0.04) compared with those with preserved RVFWLS. Impaired RVFWLS patients also showed trend towards higher prevalence of basal interventricular thinning (50 vs. 28%, P=0.12). During a median follow-up of 548 days, eleven patients had MACE. In multivariable Cox-proportional hazards model analysis, RVFWLS was independently associated with MACE (HR 1.28, 95% CI: 1.07–1.10, P=0.009). Kaplan-Meier survival curves showed worse event-free survival in patients with impaired RVFWLS (log-rank test, P=0.001).
Conclusions
In patients with CS, RVFWLS is an independent predictor for MACE. RVFWLS may be valuable in improving risk stratification in CS.

Abstract
Rate of respiration is a fundamental vital sign. Accuracy and precision of respiratory rate measurements with contact-free load cell sensors under the bed legs were assessed by breath-by-breath comparison with the pneumotachography technique during two different dynamic breathing tasks in 16 awake human adults resting on the bed. The subject voluntarily increased and decreased the respiratory rate between 4 and 16 breaths/min ( n = 8) and 10 and 40 breaths/min ( n = 8) at every 2 breaths in 6 different lying postures such as supine, left lateral, right lateral, and 30, 45, and 60° sitting postures. Reciprocal phase changes of the upper and lower load cell signals accorded with the respiratory phases indicating respiratory-related shifts of the centroid along the long axis of the bed. Bland-Altman analyses revealed 0.66 and 1.59 breaths/min standard deviation differences between the techniques (limits of agreement: −1.22 to 1.36 and −2.96 to 3.30) and 0.07 and 0.17 breaths/min fixed bias differences (accuracy) (confidence interval: 0.04 to 0.10 and 0.12 to 0.22) for the mean respiratory rates of 10.5 ± 3.7 and 24.6 ± 8.9 breaths/min, respectively, regardless of the body postures on the bed. Proportional underestimation by this technique was evident for respiratory rates >40 breaths/min. Sample breath increase up to 10 breaths improved the precision from 1.59 to 0.26 breaths/min. Abnormally faster and slower respirations were accurately detected. We conclude that contact-free unconstraint respiratory rate measurements with load cells under the bed legs are accurate and may serve as a new clinical and investigational tool. NEW & NOTEWORTHY Four load cells placed under the bed legs successfully captured a centroid shift during respiration in human subjects lying on a bed. Breath-by-breath comparison of the breaths covering a wide respiratory rate range by pneumotachography confirmed reliability of the contact-free unconstraint respiratory rate measurements by small standard deviations and biases regardless of body postures. Abnormally faster and slower respirations were accurately detected. This technique should be an asset as a new clinical and investigational tool.

Abstract
AbstractTo evaluate the QUIK-R, a revised self-completed questionnaire for the quality of life (QOL), and to clarify the significance of measuring QOL in health evaluations, the results of 1,017 office workers were analyzed. The QUIK-R showed a high reliability and a high validity. There were significant correlations between the total score and the subject’s age, sex, smoking habit, sleeping time, and exercise. Forty-two subjects with a good QUIK-R score had poor physical examination results. Our results show the usefulness of the QUIK-R and the importance of measuring the QOL in health evaluations.

Abstract
AbstractBrain natriuretic peptide (BNP) is increased in patients with heart failure due to myocardial infarction and cardiac hypertrophy, in proportion to the severity of left ventricular dysfunction. The aims of this study were to clarify the clinical features of BNP and to determine the diagnostic value of BNP for mass screening.The subjects were 818 office workers (565 males and 253 females; mean age 47 ± 12 years) who participated in a 1996 routine health check at Kansai University All individuals were examined for blood pressure, serological findings, ECG and plasma BNP level. Thirty-three males underwent 2-D echocardiography. Plasma BNP levels were measured using IRMA (immunoradiometric assay).The results were as follows: (1) BNP levels in females were higher than those in males for healthy subjects (N = 551), in each age group from 20 to 60 years. (2) BNP levels increased with age. (3) There were significant correlations between BNP level and systolic blood pressure and creatinine level. (4) There were significant differences in BNP level between the hypertensive groups with and without hypertensive ECG changes and the age-matched healthy control group. (5) Marked correlations were observed between BNP level and left ventricular wall thickness, fractional shortening, deceleration time and peak early filling velocity. (6) A BNP cut-off-point of 25 pg/ml was best for detecting LV diastolic dysfunction and LV hypertrophy. Measurement of BNP is useful for detecting asymptomatic heart failure in the general population, and is a clinical marker useful in preventing symptomatic heart failure.

Abstract
The pentafluorosulfanyl (SF5) group is more electronegative, lipophilic and sterically bulky relative to the well-explored trifluoromethyl (CF3) group. As such, the SF5 group could offer access to pharmaceuticals, agrochemicals and optoelectronic materials with novel properties. Here, the first synthesis of phthalocyanines (Pcs), a class of compounds used as dyes and with potential as photodynamic therapeutics, with a SF5 group directly attached on their peripheral positions is disclosed. The key for this work is the preparation of a series of SF5-containing phthalonitriles, which was beautifully regio-controlled by a stepwise cyanation via ortho-lithiation/iodination from commercially available pentafluorosulfanyl arenes. The macrocyclization of the SF5-containing phthalonitriles to SF5-substituted Pcs required harsh conditions with the exception of the synthesis of β-SF5-substituted Pc. The regiospecificity of the newly developed SF5-substituted Pcs observed by UV/Vis spectra and fluorescence quantum yields depend on the peripheral positon of the SF5 group.

Abstract
Metal β-tetrakis(tert-butyl)phthalocyanines are the most commonly used phthalocyanines due to their high solubility, stability, and accessibility. They are commonly used as a mixture of four regioisomers, which arise due to the tert-butyl substituent on the β-position, and to the best of our knowledge, their regioselective synthesis has yet to be reported. Herein, the C4h-selective synthesis of β-tetrakis(tert-butyl)metallophthalocyanines is disclosed. Using tetramerization of α-trialkylsilyl phthalonitriles with metal salts following acid-mediated desilylation, the desired metallophthalocyanines were obtained in good yields. Upon investigation of regioisomer-free zinc β-tetrakis(tert-butyl)phthalocyanine using spectroscopy, the C4h single isomer described here was found to be distinct in the solid state to zinc β-tetrakis(tert-butyl)phthalocyanine obtained by a conventional method.

Abstract
OBJECTIVE The incidence of foetal loss and/or adverse foetal outcomes, including congenital heart block (CHB), has been investigated in mothers with anti-SSA antibody detected by immunodiffusion or counter-immunoelectrophoresis methods. We investigated the relationship between several serum parameters (such as autoantibodies and immunoglobulins) and foetal loss in patients with anti-SSA antibody, measured by enzyme-linked immunosorbent assay (ELISA). MATERIAL AND METHODS Thirty-seven women who showed positivity for anti-SSA antibody and had a history of pregnancy were included in this study. Immunoglobulins and several autoantibodies were assayed by routine laboratory methods at our hospital. RESULTS Our data indicated that immunoglobulin E (IgE) levels were significantly higher in the anti-SSA antibody positive women with foetal loss than in those without, and that a strong positive correlation between IgE and anti-SSA antibody levels was observed in the former group, but not in the latter. CONCLUSION The serum IgE level seems to be an important factor in the occurrence of foetal loss in mothers with anti-SSA antibody detected by ELISA.

Abstract
We present the first evidence of the decay B- --> tau- nu(tau), using 414 fb(-1) of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider. Events are tagged by fully reconstructing one of the B mesons in hadronic modes. We detect the signal with a significance of 3.5 standard deviations including systematics and measure the branching fraction to be B(B- --> tau- nu(tau)) = (1.79(-0.49) +0.56(stat)(-0.51) +0.46(syst)) x 10(-4). This implies that fB = 0.229(-0.031) +0.036(stat)(-0.037) +0.034(syst) GeV and is the first direct measurement of this quantity.

Abstract
Our group, Ujike et al., recently reported that the A1 allele of TaqI A polymorphism of the dopamine receptor D2 (DRD2) gene, associated with transient psychosis, significantly differs from that of patients with prolonged psychosis in methamphetamine psychosis. Therefore, we examined the association between the TaqI A polymorphism of the DRD2 gene and the brain MRI view for patients with methamphetamine psychosis. The subjects underwent brain MRI scans using the FLAIR method. Genotyping was performed by PCR-RFLP methods using genomic DNA extracted from peripheral blood by the phenol method. Ten subjects had the A1/A2 genotype, eleven subjects had the A2/A2 genotype, and no subject had the A1/A1 genotype. The domain size, including the thalamus and basal ganglia that were inside each side of the putamens, did not differ between the three groups (the A1/A2-group, the A2/A2-group, and the young healthy person group). In the comparison based on this domain, the temporal lobe tended to narrow in the A2/A2-group compared to the A1/A2-group (P = .06). The other domain (cerebrum, corpus callosum, etc.) showed no difference between the A1/A2-group and the A2/A2-group. It is suggested that in methamphetamine psychosis the TaqI A polymorphism not only regulates prolongation of psychosis symptoms but also influences the form of the temporal lobe.

Abstract
Recent evidence has revealed that bacterial DNA can promote several of the autoimmune abnormalities observed in systemic lupus erythematosus (SLE), and a possible pathogenic role in the induction of SLE has been highlighted. We have recently encountered patients in whom bacterial infection (septicemia) triggered the production of several autoantibodies. This seems to be interesting with respect to the consideration of the relationship between SLE and bacterial infection.

Abstract
OBJECTIVES The quality of the hybrid layer is believed to be more important than the thickness of this layer. The purpose of this study was to investigate a method to analyze the percentage of adhesive resin residual double bonds in the dentin-resin interface using laser Raman spectroscopy. METHODS Bovine dentin was treated with dentin adhesives and resin composite was bonded according to the manufacturers' instructions. The specimens were sectioned parallel to dentinal tubules and the surfaces were then polished to 1 microm diamond pastes. Raman spectra were recorded along a line perpendicular to the dentin-resin interface in steps of 0.2 microm. The measurement of residual C=C bond was made on a relative basis by comparing the C=C unpolymerized methacrylate stretching vibration (1638 cm(-1)) against the C=O stretching mode of the ester group (1719 cm(-1)). The percentage of residual double bonds including pendant and monomeric double bonds was calculated by comparing the obtained ratio with that of uncured adhesive resin. RESULTS The amount of residual double bonds in the hybrid layer varied from 10 to 25% compared to the uncured adhesives, a relatively higher percentage was detected for Fluoro Bond (12.3-23.6%) and Single Bond (9.5-21.8%), and lower for Mac Bond II (10.6-18.0%) and Mega Bond (10.7-16.3%). No relationship was seen between the percentage of remaining double bonds and the location within the resin-dentin interface. SIGNIFICANCE Laser Raman microscopy used was a useful tool for measuring the residual double bonds in the dentin-resin interface.

Abstract
The relationship between allergic disorders (such as atopic dermatitis, asthma, allergic rhinitis and allergic conjunctivitis) and systemic lupus erythematosus (SLE) is still unclear and controversial. We investigated the prevalence of these allergic disorders in SLE patients and their families. A questionnaire about the history of allergy was completed by 52 SLE patients and by 52 matched (including race, age, sex and region) non-SLE controls. Our results indicated that there was a significantly lower incidence of these allergic diseases in SLE patients, especially those who had an allergic family histories, when compared with the controls. These findings may be related to the immunological similarities and differences between SLE and various allergic diseases.

Abstract
We attempted to obtain a deeper understanding of the relationship between systemic lupus erythematosus (SLE) and allergic diseases through comparative studies. Accordingly, we reviewed the association of both disorders and compared their immunological features based on the literature and our own findings. Recent studies (including ours) have indicated that the risk of IgE-mediated and/or associated allergic diseases is not markedly increased in SLE patients despite their more allergic family history when compared with controls, in contrast with earlier studies. This may be related to a change of the environmental factors contributing to allergy. In addition, assessment of the immunological similarities and differences between SLE and various allergic diseases seems to be useful for understanding the relationship between them.

Abstract
Cytomegalovirus (CMV) infection is known to induce several autoimmune abnormalities in mice that resemble those found in systemic lupus erythematosus (SLE). In addition, a potential role for CMV in the development and/or progression of SLE has been suggested. In order to further clarify this issue, we reviewed the relationship between SLE and CMV infection on the basis of the clinical and immunological features of cases reported in the literature and our own patients.

Abstract
Based on our previous results, which pointed to tumor necrosis factor-alpha (TNF-alpha) as the essential cytokine in tumor promotion in mouse skin, we present here three principal findings related to the specific roles of TNF-alpha, interleukin-1 (IL-1) and IL-6 in tumor promotion (using TNF-alpha- and IL-6-deficient mice) and in BALB/3T3 cell transformation: i) The previously reported residual tumor promotion by 12-O-tetradecanoylphorbol-13-acetate (TPA) in TNF-/- mice was confirmed by experiments with TNF+/+ and TNF-/- 129/Svj mice of the same strain, using two-stage carcinogenesis experiments. TPA produced tumors in 100% of TNF+/+ and 78% of TNF-/- mice at 20 weeks, and the average number of tumors per mouse was 11.1 in the former group and 2.1 in the latter. Judging from the expression of various inflammatory cytokine genes in TNF+/+ and TNF-/- mice, the residual tumor promoting activity of TPA in TNF-/- mice may be dependent on expression of IL-1alpha and IL-1beta genes. ii) Tumor promotion by TPA and okadaic acid in IL-6+/+ and IL-6-/- C57/BL6 mice was studied, with TPA producing tumors in 57.1% of IL-6+/+ and 40.0% of IL-6-/- mice at 20 weeks, and okadaic acid in 40.0% of IL-6+/+ and 53.3% of IL-6-/- mice. Thus, there was no significant difference between TPA or okadaic acid tumor promotion in either group. In addition, expression of IL-6 gene in skin of both types of mice suggested that IL-6 is not the essential cytokine in tumor promotion, since it can be replaced by other cytokines. iii) In transformed clones of BALB/3T3 cells induced by TNF-alpha alone, IL-1alpha gene expression was induced after transformation by TNF-alpha had occurred, which did not occur in parental cells. Expression patterns of TNF-alpha, IL-1beta, IL-6 and IL-10, along with TGF-beta, were similar in both parental and transformed cells. Considering all these results, we conclude that various cytokines have discrete roles in tumor promotion and cell transformation.

Abstract
In this study, the antiproliferative effects of vinblastine (VLB), paclitaxel (TXL), doxorubicin (DXR), daunorubicin (DNR) and 5-fluorouracil (5-FU) were assessed in the human cervical carcinoma cell line HeLa-Ohio (HeLa) and Hvr100-6 cells, established by growing the parental HeLa cells in the presence of progressively greater concentrations of VLB in the culture medium. Flow cytometric analysis indicated the induction of MDR1 (P-glycoprotein) in Hvr100-6 cells with no alterations in levels of multidrug resistance-associated protein (MRP). Resistance to VLB, TXL, DXR and DNR was found in Hvr100-6 cells with relative resistances of ca. 300, 4000, 50 and 200, respectively, whereas no resistance was found to 5-FU. The reversal effects of antifungal drugs, fluconazole, itraconazole, ketoconazole, miconazole and amphotericin B on multidrug resistance were also assessed using Hvr100-6 cells. Itraconazole was found to have potent reversal effect on the resistance to VLB and TXL, but the others had no such effect. This reversal effect of itraconazole was concentration-dependent, with dose modifying factors of 3.2, 10.1 and 435.7 at 0.1, 0.25 and 0.5 microM of itraconazole, respectively. In addition, this reversal effect of itraconazole was explained by the inhibition of accumulation of the anticancer drugs.

Abstract
Mitogen-activated protein (MAP) kinase plays important roles in the establishment of long-term potentiation both in vitro and in living animals. MAP kinase is activated in response to a broad range of stimuli, including calcium influx through NMDA receptor and L-type calcium channel, cAMP, and neurotrophins. To investigate the role of Ras in the activation of MAP kinase and cAMP response element-binding protein (CREB) in hippocampal neurons, we inhibited Ras function by overexpressing a Ras GTPase-activating protein, Gap1(m), or dominant negative Ras by means of adenovirus vectors. Gap1(m) expression almost completely suppressed MAP kinase activation in response to NMDA, calcium ionophore, membrane depolarization, forskolin, and brain-derived neurotrophic factor (BDNF). Dominant negative Ras also showed similar effects. On the other hand, Rap1GAP did not significantly inhibit the forskolin-induced activation of MAP kinase. In contrast to MAP kinase activation, the inactivation of Ras activity did not inhibit significantly NMDA-induced CREB phosphorylation, whereas BDNF-induced CREB phosphorylation was inhibited almost completely. These results demonstrate that Ras transduces signals elicited by a broad range of stimuli to MAP kinase in hippocampal neurons and further suggest that CREB phosphorylation depends on multiple pathways.

Abstract
We report the use of bilateral retroangular flaps for reconstruction of the glabella and nasal tip following extirpation of a cavernous haemangioma. The vascularity of the flaps was good, and the colour and texture match excellent. Donor-site closure was easy, and the scar in the nasolabial groove was not conspicuous. Our experience demonstrates that this flap is useful for reconstruction of skin defects of not only the nose but also the glabella and forehead. By raising bilateral flaps, a wide skin defect in the centre of the face can be repaired.

Sjögren's syndrome (SS) is known to be associated with pseudolymphoma in several organs. We describe a patient with SS complicated by a hepatic pseudolymphoma. Although the development of a hepatic pseudolymphoma is extremely rare, this disorder should be taken into consideration in the differential diagnosis of space occupying lesions related to autoimmune diseases such as SS.

Abstract
The authors investigated changes in the ratio of CD4+ to CD8+ T cells (CD4/CD8 ratio) and T-cell activation, indicated by human leukocyte antigen (HLA)-DR expression, in patients with systemic lupus erythematosus (SLE) following treatment. An increase was observed in the CD4/CD8 ratio as well as a decrease in the expression of HLA-DR on T cells with the improvement of clinical manifestations on treatment with steroids or cyclosporine (CSA). In addition, steroid treatment suppressed whereas CSA treatment exerted no perceptible influence on the serum interleukin (IL)-16 level, concurrent with changes in T-cell phenotypes. This indicated that the mechanism of the change in the CD4/CD8 ratio differed depending on the drug, and CD8+ T cells could play an important role in reducing this ratio. The CD4/CD8 ratio and HLA-DR expression may be good indicators of therapeutic efficacy in some SLE patients.

Abstract
We describe a method to repair full thickness defects of the nose using a glabellar flap as the lining of the nasal cavity and an expanded forehead flap for external closure. We consider our method useful in the reconstruction of a nose with a full thickness defect for which the flap donor site is limited. The patient was a 45-year-old man who underwent resection of a basal cell carcinoma located over the dorsum of the nose which was associated with a hemangioma simplex on the face. As a result, about two-thirds of the nose, from the dorsum to the tip, as well as a part of the right cheek became deficient and the right nasal cavity became exposed. The nose was reconstructed using the above-mentioned method. The result was satisfactory both cosmetically and functionally.

Abstract
We investigated whether a compensatory vasoconstrictor action would be induced by a hypotensive intervention in the hindquarter vascular region of conscious spontaneously hypertensive rats (SHRs). Mean arterial pressure and hindquarter blood flow were recorded. After hemorrhage (withdrawing blood, 0.3 ml/100 g body weight), hindquarter resistance (HQR) was increased significantly. The decrease in HQR induced by the administration of a ganglionic blocker (C6; 25 mg/kg, i.v.) was significantly greater in SHRs with hemorrhage than in those without hemorrhage. The present results suggest that a detectable hindquarter compensator tone occurs due to hemorrhage in SHRs, although an abnormal substantial vasoconstrictor tone already exists in the hindquarters.

Abstract
In reconstruction of full-thickness nasal defects, excellent outcome from both the cosmetic and functional viewpoints is desired, and minimal scar in the flap donor site is favored. The authors describe a new reconstructive method in which full-thickness nasal defects are repaired with a full-thickness island flap collected from the nasolabial region, with the retrograde angular artery as the pedicle. The authors call this flap the full-thickness retroangular flap, and used it to repair full-thickness nasal defects generated by resection of cutaneous malignant tumors in 2 patients. The advantages of this method were the following: reconstruction of the external side of the nose and lining of the nasal cavity could be performed with one flap; the color and texture of the reconstructed nose were favorable; being an arterial flap, good blood circulation was obtained; and closing of the flap donor site was easy.

Abstract
To evaluate the QUIK-R, a revised self-completed questionnaire for the quality of life (QOL), and to clarify the significance of measuring QOL in health evaluations, the results of 1,017 office workers were analyzed. The QUIK-R showed a high reliability and a high validity. There were significant correlations between the total score and the subject's age, sex, smoking habit, sleeping time, and exercise. Forty-two subjects with a good QUIK-R score had poor physical examination results. Our results show the usefulness of the QUIK-R and the importance of measuring the QOL in health evaluations.
