Abstract
Although KCNJ11 mutation is the main cause of neonatal diabetes mellitus, reports of maturity-onset diabetes in the young (MODY) related to KCNJ11 are rare. Here, we report a case of KCNJ11-MODY in a 12-yr-old Japanese female. Hyperglycemia was initially detected during a school urine screening program. Subsequent laboratory examinations revealed impaired insulin secretion; however, no islet autoantibodies were detected. Genetic testing of KCNJ11 revealed a novel heterozygous variant, c.153G>C, p.Glu51Asp. The patient's father had the same mutation and was diagnosed with diabetes at 46 yr of age. KCNJ11-MODY was suspected, and sulfonylurea administration resulted in adequate glycemic control in the patient. The American College of Medical Genetics and Genomics guidelines classify this variant as likely pathogenic, and the effectiveness of sulfonylureas supports its pathogenicity. The patient could be treated with 0.02-0.03 mg/kg/d of glibenclamide, as this mutation may be responsive to only a small amount of sulfonylurea. A detailed family history and sequencing of causative genes, including KCNJ11, may help diagnose diabetes in school-aged patients.

Abstract
Obesity is accompanied by and accelerated with chronic inflammation in adipose tissue, especially visceral adipose tissue (VAT). This low-level inflammation predisposes the host to the development of metabolic disease, most notably type 2 diabetes. We have focused on the capacity of glycolipid-reactive, CD1d-restricted natural killer T (NKT) cells to modulate obesity and its associated metabolic sequelae. We previously reported that CD1d knockout (KO) mice are partially protected against the development of obesity-associated insulin-resistance, and these findings were recapitulated in mice with an adipocyte-specific CD1d deficiency, suggesting that NKT cell-adipocyte interactions play a critical role in exacerbating disease. However, many other CD1d-expressing cells contribute to the in vivo responses of NKT cells to lipid antigens. In the present study, we examined the role of CD1d expression by macrophages (Mϕ) to the development of obesity-associated metabolic inflammation using LysMcre-cd1d1f/f mice where the CD1d1 gene is disrupted in a Mϕ-specific manner. Unexpectedly, these animals contained a higher frequency of T-bet+ CD4+ T cells in VAT with increased production of Th1-cytokines that aggravated VAT inflammation. Mϕ from mutant mice displayed increased production of IL-12p40, suggesting M1 polarization. These findings indicate that interactions of CD1d on Mϕ with NKT cells play a beneficial role in obesity-associated VAT inflammation and insulin resistance with a sharp contrast to an aggravating role of CD1d on another type of antigen presenting cell, dendritic cells.

Abstract
Abstract
Background
Although regular physical activity has beneficial cardiovascular effects, exercise can trigger sudden cardiac arrest (SCA). Coronary artery disease (CAD) was identified as the most common cause of an exercise-related out-of-hospital cardiac arrest (OHCA). Regular exercise has been reported to reduce the risk of plaque rupture in animal studies and basic research. Therefore, we compared the coronary artery findings in CAD-OHCA patients with and without habitual exercise.
There have been few reports on whether regular exercise changes the prognosis in OHCA due to CAD (CAD-OHCA). We investigated the association between the better clinical outcome and the regular exercise in patients with CAD-OHCA.
Methods
This is a single-center retrospective analysis from 2006 to 2019. The consecutive 397 patients with OHCA due to myocardial ischemia underwent coronary angiography (CAG). After excluding 73 patients with vasospastic angina, the remaining 324 patients with CAD were enrolled in this study. We divided these patients into two groups according to whether they were habitually exercising (Exercise group: N=37) or not/unknown (Non-Exercise group: N=287).
Clinical outcome was a 30-day survival with minimal neurologic impairment represented by a Glasgow-Pittsburgh Cerebral Performance Categories Scale value 1 or 2.
Results
The patients in the Exercise Group were significantly younger (exercise vs. non-exercise, 57±12 vs. 64±12 years; P<0.01) than those in the non-exercise group. The Exercise group had a lower incidence of diabetes mellitus (22% vs. 42%; P=0.02) and a higher incidence of dyslipidemia (81% vs. 62%; P=0.02) than the non-exercise group. The time from collapse to cardiopulmonary resuscitation (1.4±4.0 vs. 3.0±4.8min) and from collapse to return of spontaneous circulation (11.9±10.0 vs. 28.0±25.3min) were shorter in Exercise group (all p<0.05). The ST-segment elevation was recorded on electrocardiography in fewer of the Exercise group (22% vs. 63%; P<0.01). The finding of culprit lesion in the coronary arteries on arrival resulted significant differences between the 2groups (good collateral and/or TIMI3 flow: 62% vs. 25%, the plaque rupture and/or thrombus: 22% vs. 73%) (all p<0.01) (Figure 1). Kaplan-Meier curve showed Exercise group has better neurological outcome at 30days compared than Non-Exercise (95% vs 51%; P<0.001, log-rank test) (Figure 2). Multivariable Cox proportional hazards models revealed that a habitual exercise was one of the predictors of a good neurological outcome (HR 0.21, 95% CI 0.05–0.92; P=0.039).
Conclusions
The patients with habitual exercise had less plaque rupture, less coronary thrombosis than non-exercise. The patients with regular exercise had better clinical outcomes than non-exercise after CAD-OHCA.

Abstract
In recent years, the clinical importance of immunotherapy has been demonstrated in the treatment of extensive-stage small-cell lung cancer (ES-SCLC). However, immune checkpoint inhibitors (ICIs) have been shown to cause immune-related adverse events (irAEs), including autoimmune encephalitis. Here, we describe th treatment of a patient with ES-SCLC who developed immune-related encephalitis. A 68-year-old Japanese woman with ES-SCLC treated with carboplatin plus etoposide plus durvalumab 20 days earlier was admitted to our hospital with a high fever and anorexia. Her symptoms gradually worsened over time, and she had a headache daily and showed reduced levels of consciousness. An electroencephalogram showed diffuse slow waves, and there was a slight increase in cell counts and an increase in protein levels in the cerebrospinal fluid. The patient was diagnosed with durvalumab-associated encephalitis. Her symptoms improved immediately after steroid pulse therapy. Following steroid pulse therapy, oral prednisolone (1 mg/kg) was administered, and then, the dose was gradually reduced. Subsequently, treatment with carboplatin plus etoposide without durvalumab was restarted. In conclusion, this study shows the efficacy of steroid therapy in the treatment of durvalumab-induced encephalitis in ES-SCLC.

Abstract
Analytical pipeline, which is used for various analysis application, of CellProfiler, an open-source software for cell imaging analysis, is very important. In the present study, to examine whether intracellular proteins can be discriminated using a combination of CellProfiler and ImageJ, we analyzed neuroblastoma and monocytic cell lines, and disease-specific induced pluripotent stem cell (iPSC)-derived neurons. This revealed that scattered puncta of Rab7 and transferrin in neuroblastoma lines were clearly detectable by created analytical pipelines in CellProfiler. We then constructed pipelines for measuring the distance from the center of the nucleus to allow investigation of the intracellular localization of Rab7 or transferrin. Using CellProfiler and ImageJ in combination, we confirmed that our pipelines were applicable both quantitatively and objectively to analysis of membrane trafficking of proteins such as Rab proteins and transferrin. In addition, when applied to quantitative measurement of phagocytosis, our pipelines clearly detected monocytic cell lines that had engulfed bioparticles. Finally, we developed new pipelines for analysis of disease phenotype using iPSCs from a patient with familial Parkinson's disease (PD), harboring the I2020T LRRK2 mutation (PARK8). These were able to successfully detect Rab5 puncta and Rab7 puncta in PARK8 patient iPSC-derived neurons. Interestingly, in long-term culture, we found that the numbers of Rab7 puncta in a single PARK8 patient iPSC-derived neurons were lower than that of control iPSC-derived neurons. On the other hands, at 14 days in vitro, the numbers of Rab5 puncta in PARK8 patient iPSC-derived neurons were lower than those of isogenic iPSC-derived neurons, but not Rab7 puncta. Furthermore, Rab5 puncta of PARK8 patient iPSC-derived neurons exhibited distinct localization pattern relative to isogenic iPSC-derived neurons. These present results suggest that this new analytical tool can be used as a supporting method for quantification of intracellular protein.

Abstract
Abstract
Background and purpose
Many reports have examined electrocardiographic (ECG) changes after subarachnoid hemorrhage from long ago; however, there are few reports on the prognosis of patients who have an ECG abnormality. Therefore, in this study, the prognoses of patients with subarachnoid hemorrhage showing abnormal ECG findings were retrospectively analyzed.
Methods
Over 30 months from January 2014 to June 2016, 199 patients (mean age, 61.1±17.0 years; 46.7% male) admitted with a subarachnoid hemorrhage (SAH) were enrolled. To assess the mechanism underlying abnormal ECG in the SAH, predictor variables, such as demographics (age, sex, and body surface area), hemodynamics (heart rate and systolic blood pressure), blood biochemical results, neurological assessments (Glasgow Coma Scale), and computed tomography (CT) severity classification (World Federation of Neurosurgical Societies classification) were recorded. The subarachnoid hemorrhage was classified into either the cerebral aneurysm rupture group (N=132) or traumatic subarachnoid hemorrhage group (N=67) and analyzed.
Results
In the cerebral aneurysm rupture group, the QT prolongation was significantly increased compared with the traumatic subarachnoid hemorrhage group (424.8±87.7 ms vs. 400.5±95.8 ms, P<0.05). There was a correlation between consciousness level (Glasgow Coma Scale) on admission and QT prolongation, and significant QT prolongation was observed in critical patients (Pearson's correlation coefficient test P=0.04). ST changes correlated with CT classification severity (WFNS classification), and the most severe group (WFNS Grade 5) showed significant ST changes. On admission, the cerebral aneurysm rupture group and 97.0% in the traumatic subarachnoid hemorrhage group.
Conclusions
Significantly prolonged QT and ST changes are noted in patients with severe aneurysmal subarachnoid hemorrhage. The cause of the ECG abnormality in subarachnoid hemorrhage patients is not yet understood. A small number of experimental animal models have shown that electrocardiogram abnormalities associated with subarachnoid hemorrhage develop in the brain stem, and an autonomic nerve abnormality may also be involved.
A D-dimer is positively correlated with both aneurysm trauma and traumatic subarachnoid hemorrhage and may be used for auxiliary diagnosis of a subarachnoid hemorrhage.

Abstract
Water mist generated during a rocket launch is thought to protect the rocket and payloads from acoustic noise. The size of mist particles is essential to understanding the effect on noise reduction. A two-wavelength multi-static lidar was developed for measuring water mist size at the launch site. The lidar determines particle size from signals at three scattering angles at two wavelengths. The method was tested with artificial mist and applied to the Japan Aerospace Exploration Agency's H-IIA/B large-scale rocket launches. The measured particle size near the outside edge of the mist cloud was 3.5-5 μm in diameter. The extinction coefficient at 532 nm derived using the Klett backward inversion method was 100-200 km-1. The estimated liquid water content (LWC) was ∼0.3 g/m3. The extinction coefficient was high, but the LWC was comparable to that of the water clouds.

Abstract
Abstract
Background
Chemotherapy for breast cancer causes alopecia as a side effect. Some patients refuse chemotherapy because of alopecia, resulting in the omission of a standard therapy. It is believed that a scalp cooling device can prevent alopecia by promoting vasoconstriction of the scalp and reducing exposure of the hair root cells to anticancer agents. There are phenotypic differences of the efficacy of a scalp cooling device for alopecia. In fact, a Dutch scalp cooling registry reported that the success rate of scalp cooling was 51% in European women and 33% in Asian women. Therefore, we aimed to investigate the efficacy of scalp cooling device for chemotherapy-induced alopecia among Asian women with breast cancer.
Trial design
This is a phase II trialto evaluate the efficacy and safety of scalp cooling device for risk reduction of alopecia in women with stage I/II/III breast cancer treated with adjuvant/neoadjuvant chemotherapy in a single institute.
Eligibility criteria
Women diagnosed with Stage I to III breast cancer who are scheduled to receive preoperative or postoperative adjuvant chemotherapy containing anthracycline and/or taxanes are enrolled. Patients who have blood malignancies (leukemia, non-Hodgkin lymphoma, other systemic lymphoma), and cold allergy, are excluded.
Specific aims
The primary endpoint is the proportion of patients with Common Terminology Criteria for Adverse Events (CTCAE) grade 0-1 alopecia after the completion of all cycles of chemotherapy (success rate). Secondary endpoints are safety, quality of life, use of wig or cap, and success rates after the completion of all cycles of chemotherapy distinguished by anthracycline(AC) and taxane.
The cooling device is the Paxman scalp cooling system. Scalp cooling was performed from 30 mins before initiation until 90 mins (25 min for taxane) after chemotherapy. Pictures of the scalp were taken at the time of the initiation of each course.
Statistical methods
Successful treatment was defined as the presence of less than 50% of hair-loss area. The sample size was calculated using the Simon method, with a type I error of 10% (two-sided) and a study power of 80%.The expected success rate is 30%, with a threshold success rate of 10%, and the required number of patients was estimated to be 19.
Present and target accrual
Patient accrual was started in April 2018 and present accrual is 3. We plan to enroll a total of 20 patients in the trial.

Abstract
Abstract
Background
Paclitaxel (PTX) is a standard treatment for metastatic breast cancer (MBC) and it is often used as adjuvant and neoadjuvant chemotherapy for patients with early-stage disease. Nanoparticle albumin-bound (Nab)-PTX was also effective in patients with metastatic and early-stage. A comparison of weekly and triweekly nab-PTX regimens suggested that weekly nab-PTX resulted in superior progression-free survival. However, the optimal dose and schedule of weekly nab-PTX have not been determined. The efficacy and tolerability of epirubicin/cyclophosphamide (EC) followed by weekly nab-PTX (125 mg/m2) ± trastuzumab in node-positive breast cancer was determined in our previous trial. A high pathologic complete response (pCR) rate was obtained in HER2-positive patients. However, because nab-PTX administration was frequently postponed and discontinued, the optimal dose needs to be determined. In the previous trial, the median relative dose intensity of nab-PTX was 80% among patients with pCR. Therefore the dose of nab-PTX was reduced by 20% in this newly designed trial.
Trial design
This phase II trial aimed to evaluate the efficacy and toxicity of neoadjuvant EC followed by weekly nab-PTX with trastuzumab in patients with HER2-positive breast cancer. Patients will receive 4 cycles of epirubicin (90 mg/m2) and cyclophosphamide (600 mg/m2) every 3 weeks, followed by 4 cycles of nab-PTX (100 mg/m2) on days 1, 8, and 15, over a 28-day cycle. Fifteen cycles of trastuzumab (2 mg/kg, loading dose: 4 mg/kg) will be added to the nab-PTX regimen.
Eligibility criteria
Surgery and chemotherapy-naïve patients with pathologically confirmed T2-4 N0-3 invasive breast cancer, as diagnosed by core needle biopsy, are included. Eligibility criteria include age 20–70 years, a performance status of 0–2, and adequate organ function.
Specific aims
The primary endpoint is the pCR rate in the breast and axilla. Secondary endpoints include the breast conservation rate, toxicities, relative dose intensities, feasibility, and overall survival. A pCR is defined as the disappearance of invasive cancer cells, including in the axilla; residual intraductal cancer is acceptable.
Statistical methods
The sample size was calculated using the Simon method, with a type I error of 5% and a study power of 80%. The expected rate of pCR is 72% with a threshold pCR rate of 45%. The required number of patients was estimated to be 25.
Present and target accrual
Patient accrual within two medical centers began in May 2014. A final study population of 30 patients is expected (Trial registration: UMIN000013886).

Abstract
Abstract
Background
The meta-analysis of the Early Breast Cancer Trialists' Collaborative Group (EBCTCG) revealed that whole-breast irradiation after breast conserving surgery (BCS) decreased ipsilateral breast tumor recurrence (IBTR) and breast cancer-related death. However, elderly patients can find daily hospital attendance difficult, and their IBTR risk is low. A randomized control trial was performed in women aged ≥70 years with hormone-positive breast cancer to investigate the usefulness of breast-conserving therapy without irradiation (Hughes et al. N Engl J Med 2004). Since September 2001, we have offered BCS plus hormone therapy without irradiation in patients who satisfy the following criteria: age ≥60 years; pathologically node negative, hormone-positive breast cancer; a negative surgical margin; and no lymphovascular invasion. We assessed prognosis in patients who chose this option.
Patients and methods
Between September 2001 and December 2014, 219 patients met the inclusion criteria; 90 and 129 patients underwent BCS plus hormone therapy with or without irradiation, respectively. The cumulative IBTR incidence and overall survival (OS) for the groups was evaluated. A negative surgical margin was defined as a margin of ≥5 mm.
Results
The median ages at operation were 73 years (range, 60–88 years) and 65 years (range, 60–80 years) for the without and with irradiation groups, respectively (p <0.001). There were no significant differences in tumor size, lymph node metastasis, or adjuvant therapy between the groups. The median follow-up duration is presently 4.6 years. IBTR was observed in 5 (3.9%) and 1 (1.1%) patient(s) in the without and with irradiation groups, respectively (p = 0.192). The 5-year IBTR cumulative incidences were 0.9% and 2.2%, and the 10-year were 6.7% and 2.2%, for the without and with irradiation groups, respectively (p = 0.390). The 5-year OS rates were 93.8% and 98.5%, and the 10-year OS rates were 89.7% and 94.0 for the without and with irradiation groups, respectively (p = 0.205).
Conclusion
BCS plus hormone therapy without irradiation in elderly patients is an appropriate option.

Abstract
In seasonally breeding animals, the circadian and photoperiodic regulation of neuroendocrine system is important for precisely-timed reproduction. Kisspeptin, encoded by the Kiss1 gene, acts as a principal positive regulator of the reproductive axis by stimulating gonadotrophin-releasing hormone (GnRH) neurone activity in vertebrates. However, the precise mechanisms underlying the cyclic regulation of the kisspeptin neuroendocrine system remain largely unknown. The grass puffer, Takifugu niphobles, exhibits a unique spawning rhythm: spawning occurs 1.5-2 h before high tide on the day of spring tide every 2 weeks, and the spawning rhythm is connected to circadian and lunar-/tide-related clock mechanisms. The grass puffer has only one kisspeptin gene (kiss2), which is expressed in a single neural population in the preoptic area (POA), and has one kisspeptin receptor gene (kiss2r), which is expressed in the POA and the nucleus dorsomedialis thalami. Both kiss2 and kiss2r show diurnal variations in expression levels, with a peak at Zeitgeber time (ZT) 6 (middle of day time) under the light/dark conditions. They also show circadian expression with a peak at circadian time 15 (beginning of subjective night-time) under constant darkness. The synchronous and diurnal oscillations of kiss2 and kiss2r expression suggest that the action of Kiss2 in the diencephalon is highly dependent on time. Moreover, midbrain GnRH2 gene (gnrh2) but not GnRH1 or GnRH3 genes show a unique semidiurnal oscillation with two peaks at ZT6 and ZT18 within a day. The cyclic expression of kiss2, kiss2r and gnrh2 may be important in the control of the precisely-timed diurnal and semilunar spawning rhythm of the grass puffer, possibly through the circadian clock and melatonin, which may transmit the photoperiodic information of daylight and moonlight to the reproductive neuroendocrine centre in the hypothalamus.

Abstract
Clinically severe or morbid obesity (body mass index (BMI) >40 or 50 kg m(-2)) entails far more serious health consequences than moderate obesity for patients, and creates additional challenges for providers. The paper provides time trends for extreme weight categories (BMI >40 and >50 kg m(-2)) until 2010, using data from the Behavioral Risk Factor Surveillance System. Between 2000 and 2010, the prevalence of a BMI >40 kg m(-2) (type III obesity), calculated from self-reported height and weight, increased by 70%, whereas the prevalence of BMI >50 kg m(-2) increased even faster. Although the BMI rates at every point in time are higher among Hispanics and Blacks, there were no significant differences in trends between them and non-Hispanic Whites. The growth rate appears to have slowed down since 2005. Adjusting for self-report biases, we estimate that in 2010 15.5 million adult Americans or 6.6% of the population had an actual BMI >40 kg m(-2). The prevalence of clinically severe obesity continues to be increasing, although less rapidly in more recent years than prior to 2005.

Abstract
In recent years, significant progress was achieved in the field of nanomedicine and bioimaging, but the development of new biomarkers for reliable detection of diseases at an early stage, molecular imaging, targeting and therapy remains crucial. The disadvantages of commonly used organic dyes include photobleaching, autofluorescence, phototoxicity and scattering when UV (ultraviolet) or visible light is used for excitation. The limited penetration depth of the excitation light and the visible emission into and from the biological tissue is a further drawback with regard to in vivo bioimaging. Lanthanide containing inorganic nanostructures emitting in the near-infrared (NIR) range under NIR excitation may overcome those problems. Due to the outstanding optical and magnetic properties of lanthanide ions (Ln(3+)), nanoscopic host materials doped with Ln(3+), e.g. Y2O3:Er(3+),Yb(3+), are promising candidates for NIR-NIR bioimaging. Ln(3+)-doped gadolinium-based inorganic nanostructures, such as Gd2O3:Er(3+),Yb(3+), have a high potential as opto-magnetic markers allowing the combination of time-resolved optical imaging and magnetic resonance imaging (MRI) of high spatial resolution. Recent progress in our research on over-1000 nm NIR fluorescent nanoprobes for in vivo NIR-NIR bioimaging will be discussed in this review.

Abstract
Abstract
Background: Paclitaxel is considered standard treatment for metastatic breast cancer (MBC) and is often used as adjuvant and neoadjuvant chemotherapy for patients with early-stage disease. Conventional paclitaxel requires solvents such as polyoxyethylated castor oil; however, such solvents are associated with toxicity including peripheral neuropathy and hypersensitivity reaction. Moreover, the use of the drug requires special tubing and in-line filters. Therefore, nanoparticle albumin-bound paclitaxel (nab-PTX) requiring no solvent has been developed. Nab-PTX was effective in patients with MBC and as a neoadjuvant therapy. A comparison between weekly and triweekly nab-PTX suggested that weekly nab-PTX was superior in progression-free survival.
Trial design: This is a phase II trial to evaluate the efficacy and toxicity of neoadjuvant epirubicin/cyclophosphamide (EC) (epirubicin/cyclophosphamide) followed by weekly nab-PTX with or without trastuzumab for node-positive breast cancer. Patients receive four cycles of epirubicin (90 mg/m2) and cyclophosphamide (600 mg/m2) every 3 weeks, followed by four cycles of nab-PTX (125 mg/m2) on days 1, 8 and 15 in a 28-day cycle. Fifteen cycles of trastuzumab (2 mg/kg, loading 4 mg/kg) are added to the nab-PTX regimen in HER2-positive patients every week.
Eligibility criteria: Patients with histologically diagnosed invasive breast cancer based on a core needle biopsy of the T1-4 N1-3 without previous operation or chemotherapy are included in this trial. Eligible patients are aged between 20 years and 70 years with a performance status of 0 to 2 and adequate organ functions.
Specific aims: The primary endpoint is the pathologic complete response (pCR) rate in the breast and axilla, and the secondary endpoints are the breast conserving rate, toxicities, feasibility and overall survival.
Statistical methods: The sample size was calculated using the Simon method, with a type I error of 10% and a study power of 80%. 1. HER2-negative patients
The expected rate of pCR was 25% and the required number of patients was estimated to be 33. 2. HER2-positive patients
The expected rate of pCR was 50%, and the required number of patients was estimated to be 21.
Present and target accrual: Patient accrual within two medical centers started in April 2011 with 20 patients being on study to date (2012, June 12). A total of 56 patients (22 are HER2-positive and 34 are HER2-negative) are planned to be enrolled in the trial.

Abstract
BACKGROUND AND PURPOSE OCT has been reported as a high-resolution imaging tool for characterizing plaque in the coronary arteries. The present study aimed to evaluate the ability of OCT to visualize carotid artery plaques compared with that of IVUS in asymptomatic and symptomatic patients. MATERIALS AND METHODS OCT was performed for 34 plaques (17 symptomatic, 17 asymptomatic) in 30 patients during CAS under a proximal cerebral protection method. OCT was performed before balloon angioplasty and after stent placement. IVUS was also performed just after OCT. RESULTS No technical or neurologic complications were encountered by using OCT. An inner catheter was used in 12 of 34 procedures (35.3%) for advancing the OCT image wire beyond the site of stenosis. OCT clearly visualized intraluminal thrombus in 15 of 34 plaques (44.1%), whereas IVUS detected a thrombus in 1 plaque (2.9%, P < .001). Neovascularization was demonstrated in 13 of 34 plaques (38.2%) by OCT, but not by IVUS (0%, P < .001). Intraluminal thrombus was more frequently observed in symptomatic plaques (13 of 17, 76.5%) than in asymptomatic plaques (2 of 17, 11.8%; P < .001). Interobserver and intraobserver variability with OCT diagnosis was excellent for thrombus, ulceration, neovascularization, and lipid pool. CONCLUSIONS The present findings suggest that OCT can safely and precisely visualize human carotid plaques during CAS and that intraluminal thrombus and neovascularization are more frequently detected in symptomatic plaques.

Abstract
Among the RFamide peptide family, the LPXRFamide peptide (LPXRFa) group regulates the release of various pituitary hormones and, recently, LPXRFa genes were found to be regulated by photoperiod via melatonin. As a first step towards investigating the role of LPXRFa on reproductive function in grass puffer (Takifugu niphobles), which spawns in semilunar cycles, genes encoding LPXRFa and its receptor (LPXRFa-R) were cloned, and seasonal, diurnal and circadian changes in their absolute amounts of mRNAs in the brain and pituitary were examined by quantitative real-time polymerase chain reaction. The grass puffer LPXRFa precursor contains two putative RFamide peptides and one possible RYamide peptide. LPXRFa and LPXRFa-R genes were extensively expressed in the diencephalon and pituitary. The expression levels of both genes were significantly elevated during the spawning periods in both sexes in the brain and pituitary, although they were low in the spawning fish just after releasing eggs and sperm. The treatment of primary pituitary cultures with goldfish LPXRFa increased the amounts of follicle-stimulating hormone β- and luteinising hormone β-subunit mRNAs. In the diencephalon, LPXRFa and LPXRFa-R genes showed synchronised diurnal and circadian variations with one peak at zeitgeber time 3 and circadian time 15, respectively. The correlated expression patterns of LPXRFa and LPXRFa-R genes in the diencephalon and pituitary and the possible stimulatory effects of LPXRFa on gonadotrophin subunit gene expression suggest the functional significance of the LPXRFa and LPXRFa-R system in the regulation of lunar-synchronised spawning of grass puffer.
