Abstract
Introduction Heterotopic salivary gland tissue (HSGT) is diagnosed when salivary gland tissue is found in areas other than the major or minor salivary glands. No dermoscopic findings of HSGT have been reported. Case Presentation This case report gives the dermoscopic findings of a 45-year-old woman with HSGT who presented with a longstanding pale red macule on her neck, characterized by repeated clear fluid discharge. Dermoscopic examination showed a red dot with a pale pink halo and telangiectasia throughout the lesion. An excisional biopsy confirmed the diagnosis of HSGT, revealing the presence of mucous and serous salivary glandular structures within subcutaneous fat tissue. It has been reported that HSGT is associated with periductal lymphocytic infiltration, which was also observed in this case. Conclusion We think that the "red dot with a pale pink halo" is a unique dermoscopic finding of HSGT, which is rarely observed in branchial anomalies.

Abstract
OBJECTIVE The Japanese Psycho-Oncology Society and the Japanese Association of Supportive Care in Cancer have recently revised the clinical practice guidelines for delirium in adult cancer patients. This article reports the process of developing the revised guidelines and summarizes the recommendations made. METHODS The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multi-disciplinary members, created three new clinical questions: non-pharmacological intervention and antipsychotics for the prevention of delirium and trazodone for the management of delirium. In addition, systematic reviews of nine existing clinical questions have been updated. Two independent reviewers reviewed the proposed articles. The certainty of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development, and Evaluation system. The modified Delphi method was used to validate the recommended statements. RESULTS This article provides a compendium of the recommendations along with their rationales, as well as a short summary. CONCLUSIONS These revised guidelines will be useful for the prevention, assessment and management of delirium in adult cancer patients in Japan.

Abstract
OBJECTIVES To reduce cancer care disparities in people with mental illness, this study aimed to quantify psychiatric care providers' perceptions regarding issues that are insufficiently addressed or difficult to address. METHODS Psychiatric care providers at 23 psychiatric hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 15 items with four categories related to insufficiencies/difficulties in cancer care for patients with mental illness on a five-point Likert scale. We analyzed the proportion of respondents who answered "insufficient/difficult" for each item. RESULTS A total of 255 (76.3%) psychiatric care providers responded. For questions related to the skills and attitudes of psychiatric professionals, 48.3%-58.4% of respondents perceived that efforts for supporting cancer screening and treatment were insufficient. For the questions related to collaborations between cancer and psychiatric care providers, 75.3% of respondents perceived that inpatient visits between psychiatric and cancer hospitals were insufficient. For the questions related to in-psychiatric-hospital medical systems, 50.2%-87.2% of respondents perceived that support for screening, diagnosis/treatment, and palliative care for psychiatric inpatients were insufficient/difficult. 41.9%-57.4% of respondents perceived that social services in the community were insufficient. CONCLUSIONS This study clarified the level of insufficiency/difficulty perceived by psychiatric care providers regarding issues related to cancer care for people with mental illness. Psychiatric care providers are required to have knowledge and skills in cancer screening and treatment. To improve access to cancer prevention, treatment, and palliative care, it may be helpful to establish systems to promote coordination between cancer hospitals and psychiatric hospitals.

Abstract
OBJECTIVES To reduce cancer care disparities, this study aimed to clarify the difficulties in cancer care for people with mental disorders as perceived by cancer care providers. METHODS Cancer care providers at 17 designated cancer hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 29 items related to difficulties or insufficiencies in cancer care for patients with mental disorders on a five-point Likert scale. We analyzed the proportion of respondents who answered "difficult/insufficient" in each item. We also calculated the proportions of responders stratified according to the presence of psychiatric support systems within their hospitals. RESULTS A total of 388 (58.4%) cancer care providers responded. Among the issues related to "difficulties in diagnosing and treating cancer," support for decision-making, assessment of treatment adherence, and assessment of physical symptoms were perceived as most difficult (73.5%-81.5% of respondents). Among the issues related to 'difficulties or insufficiencies in collaboration among multidisciplinary health care providers,' the issue of advance consultation and sharing information with the patient's primary psychiatric care provider was perceived as most difficult (52.2%). Among the issues related to "insufficiencies of in-hospital and community medical systems," education to provide reasonable accommodation was perceived as most insufficient (47.4%). The perceived difficulties of over half of the issues varied significantly between hospitals depending on the level of psychiatric support systems. CONCLUSIONS This study clarified the difficulties of cancer care in patients with mental disorders as perceived by cancer care providers. Some issues may be resolved by psychiatric liaison teams.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (COVID-19) is an acute respiratory infection transmitted by droplets, aerosols, and contact. Controlling the spread of COVID-19 and developing effective decontamination options are urgent issues for the international community. Here, we report the quantitative inactivation of SARS-CoV-2 in liquid and aerosolized samples by a state-of-the-art, high-power, AlGaN-based, single-chip compact deep-UV (DUV) light-emitting diode (LED) that produces a record continuous-wave output power of 500 mW at its peak emission wavelength of 265 nm. Using this DUV-LED, we observed a greater-than-5-log reduction in infectious SARS-CoV-2 in liquid samples within very short irradiation times (<0.4 s). When we quantified the efficacy of the 265-nm DUV-LED in inactivating SARS-CoV-2, we found that DUV-LED inactivation of aerosolized SARS-CoV-2 was approximately nine times greater than that of SARS-CoV-2 suspension. Our data demonstrate that this newly developed, compact, high-power 265-nm DUV-LED irradiation system with remarkably high inactivation efficiency for aerosolized SARS-CoV-2 could be an effective and practical tool for controlling SARS-CoV-2 spread. IMPORTANCE We developed a 265-nm high-power DUV-LED irradiation system and quantitatively demonstrated that the DUV-LED can inactivate SARS-CoV-2 in suspensions and aerosols within very short irradiation times. We also found that the inactivation effect was about nine times greater against aerosolized SARS-CoV-2 than against SARS-CoV-2 suspensions. The DUV-LED has several advantages over conventional LEDs and mercury lamps, including high power, compactness, and environmental friendliness; its rapid inactivation of aerosolized SARS-CoV-2 opens up new possibilities for the practical application of DUV-LEDs in high-efficiency air purification systems to control airborne transmission of SARS-CoV-2.

Abstract
The clinical benefit of perospirone for treatment of delirium in patients with advanced cancer is not sufficiently clear. The objective of this study was to compare the safety and effectiveness of perospirone to those of risperidone for the treatment of delirium in patients with advanced cancer. This is a secondary analysis of a multicenter prospective observational study in nine psycho-oncology consultation services in Japan. The study used the Delirium Rating Scale (DRS) Revised-98 to measure effectiveness and the CTCAE (Common Terminology Criteria for Adverse Events) version 4 to assess safety. Data from 16 patients who received perospirone and 53 patients who received risperidone were analyzed. The mean age was 70 years in the perospirone group and 73 years in the risperidone group. Both groups showed a significant decrease in the total score of DRS-R-98 after three days of treatment (perospirone: 11.7 (7.9-15.4) to 7.0 (3.3-10.7), difference -4.7, effect size=0.72, p=0.003; risperidone: 15.5 (13.6-17.4) to 12.2 (10.1-14.2), difference -3.3, effect size=0.55, p=0.00). The risperidone group showed significant improvements in sleep-wake cycle disturbance, orientation, attention, and visuospatial ability. In the perospirone group, there was a significant improvement of sleep-wake cycle disturbance. The median daily dose of perospirone was 4 mg/day. There were fewer episodes of somnolence as an adverse event in the perospirone group. Low-dose perospirone was thus found to be effective for the treatment of delirium in patients with advanced cancer and may be associated with fewer episodes of over-sedation as an adverse event.

Abstract
Plasma membrane (PM) H+-ATPase in guard cells is activated by phosphorylation of the penultimate residue, threonine (Thr), in response to blue and red light, promoting stomatal opening. Previous in vitro biochemical investigation suggested that Mg2+- and Mn2+-dependent membrane-localized type 2C protein phosphatase (PP2C)-like activity mediates the dephosphorylation of PM H+-ATPase in guard cells. PP2C clade D (PP2C.D) was later demonstrated to be involved in PM H+-ATPase dephosphorylation during auxin-induced cell expansion in Arabidopsis (Arabidopsis thaliana). However, it is unclear whether PP2C.D phosphatases are involved in PM H+-ATPase dephosphorylation in guard cells. Transient expression experiments using Arabidopsis mesophyll cell protoplasts revealed that all PP2C.D isoforms dephosphorylate the endogenous PM H+-ATPase. We further analyzed PP2C.D6/8/9, which display higher expression levels than other isoforms in guard cells, observing that pp2c.d6, pp2c.d8, and pp2c.d9 single mutants showed similar light-induced stomatal opening and phosphorylation status of PM H+-ATPase in guard cells as Col-0. In contrast, the pp2c.d6/9 double mutant displayed wider stomatal apertures and greater PM H+-ATPase phosphorylation in response to blue light, but delayed dephosphorylation of PM H+-ATPase in guard cells; the pp2c.d6/8/9 triple mutant showed similar phenotypes to those of the pp2c.d6/9 double mutant. Taken together, these results indicate that PP2C.D6 and PP2C.D9 redundantly mediate PM H+-ATPase dephosphorylation in guard cells. Curiously, unlike auxin-induced cell expansion in seedlings, auxin had no effect on the phosphorylation status of PM H+-ATPase in guard cells.

Abstract
BACKGROUND Clinical observations have shown that there is a relationship between coronavirus disease 2019 (COVID-19) and atypical lymphocytes in the peripheral blood; however, knowledge about the time course of the changes in atypical lymphocytes and the association with the clinical course of COVID-19 is limited. OBJECTIVE Our purposes were to investigate the dynamics of atypical lymphocytes in COVID-19 patients and to estimate their clinical significance for diagnosis and monitoring disease course. MATERIALS AND METHODS We retrospectively identified 98 inpatients in a general ward at Kashiwa Municipal Hospital from May 1st, 2020, to October 31st, 2020. We extracted data on patient demographics, symptoms, comorbidities, blood test results, radiographic findings, treatment after admission and clinical course. We compared clinical findings between patients with and without atypical lymphocytes, investigated the behavior of atypical lymphocytes throughout the clinical course of COVID-19, and determined the relationships among the development of pneumonia, the use of supplemental oxygen and the presence of atypical lymphocytes. RESULTS Patients with atypical lymphocytes had a significantly higher prevalence of pneumonia (80.4% vs. 42.6%, p < 0.0001) and the use of supplemental oxygen (25.5% vs. 4.3%, p = 0.0042). The median time to the appearance of atypical lymphocytes after disease onset was eight days, and atypical lymphocytes were observed in 16/98 (16.3%) patients at the first visit. Atypical lymphocytes appeared after the confirmation of lung infiltrates in 31/41 (75.6%) patients. Of the 13 oxygen-treated patients with atypical lymphocytes, approximately two-thirds had a stable or improved clinical course after the appearance of atypical lymphocytes. CONCLUSION Atypical lymphocytes frequently appeared in the peripheral blood of COVID-19 patients one week after disease onset. Patients with atypical lymphocytes were more likely to have pneumonia and to need supplemental oxygen; however, two-thirds of them showed clinical improvement after the appearance of atypical lymphocytes.

Abstract
OBJECTIVE It is widely assumed that there are multiple levels (from individual to policy level) of problems involving disparities in cancer care for people with mental disorders. However, few studies have comprehensively investigated issues as perceived by medical professionals. The purpose of the present study was to identify a wide range of issues in cancer care for people with mental disorders and offer corresponding solutions for both cancer care professionals and psychiatric care professionals. METHODS We distributed open-ended questionnaires to 754 healthcare professionals in various medical facilities, including designated cancer hospitals, psychiatric hospitals, and other local healthcare/welfare facilities. Participants were asked to describe issues in cancer care for people with mental disorders. RESULTS Of the 754 recruited professionals, 439 (58.2%) responded to the questionnaire. Sixty-one issues were extracted and categorized into 10 categories: patient factors; isolation and lack of support; obstacles to transport; socioeconomic factors; attitudes of psychiatric professionals; medical system of psychiatric hospitals; attitudes of cancer care professionals; medical system of designated cancer hospitals; regional cancer medical systems; and lack of coordination among multidisciplinary healthcare professionals. Forty-eight specific solutions were summarized into 12 goals. CONCLUSIONS The present study widely identified issues causing disparities in cancer care for patients with mental disorders. We found that the issues extended from the patient level to the public-policy level. Our findings suggest the need for a multidisciplinary approach that includes both cancer and psychiatric care professionals to address the gap in cancer care for people with mental disorders.

Abstract
Background: Clinical usefulness of trazodone for delirium in patients receiving palliative care is unclear. Objectives: To examine the safety and effectiveness of trazodone for delirium. Design: A secondary analysis of a multicenter prospective observational study. Setting/Subjects: The setting involves nine psycho-oncology consultation services and 14 inpatient palliative care units in Japan. Measurements: The measurement involves the Delirium Rating Scale (DRS) Revised-98 for effectiveness and the CTCAE (Common Terminology Criteria for Adverse Events) version 4 for safety assessments. Results: Thirty-eight patients enrolled the study. Mean age was 75 years. After three-day observation, the DRS total score (11.6 ± 5.3 to 8.7 ± 6.5 [difference -2.9, 95% confidence interval -5.3 to -0.5, p = 0.02]); sleep-wake cycle disturbance (p = 0.047), lability of affect (p < 0.001), and motor agitation subscales (p < 0.001) were significantly decreased. The most frequent adverse event was somnolence (n = 9). Conclusions: Low-dose trazodone treatment was generally safe and may be effective in reducing delirium severity.

Abstract
BACKGROUND The Japanese Psycho-Oncology Society and Japanese Association of Supportive Care in Cancer recently launched the clinical practice guidelines for delirium in adult cancer patients. The aim of the guidelines was to provide evidence-based recommendations for the clinical assessment and management of delirium in cancer patients. This article reports the process of developing the guideline and summarizes the recommendations made. METHODS The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multidisciplinary members, formulated nine clinical questions. A systematic literature search was conducted to identify relevant articles published prior to through 31 May 2016. Each article was reviewed by two independent reviewers. The level of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development and Evaluation system. The modified Delphi method was used to validate the recommendation statements. RESULTS This article provides a summary of the recommendations with rationales for each, as well as a short summary. CONCLUSIONS These guidelines will support the clinical assessment and management of delirium in cancer patients. However, additional clinical studies are warranted to further improve the management of delirium.

Abstract
Hexagonal boron nitride (h-BN) is an attractive wide-bandgap material for application to emitters and detectors operating in the deep ultraviolet (DUV) spectral region. The optical transmittance of h-BN in the DUV region is particularly important for these devices. We report on the deposition of thick h-BN films (>200 nm) on Al0.7Ga0.3N templates via radio-frequency sputtering, along with the realization of ultrahigh transmittance in the DUV region. The fraction of the gas mixture (Ar/N2) was varied to investigate its effects on the optical transmittance of BN. DUV light transmittance of as high as 94% was achieved at 265 nm. This value could be further enhanced to exceed 98% by a post-annealing treatment at 800 °C in a N2 ambient for 20 min. The phase of the highly DUV-transparent BN film was determined to be a purely hexagonal structure via Raman spectra measurements. More importantly, these deposition processes were performed at a low temperature (300 °C), which can provide protection from device performance degradation when applied to actual devices.

Abstract
A 79-year-old woman presented with fever and general malaise. Examination revealed hepatic injury, thrombocytopenia, skin lesions, and regional lymphadenopathy; severe fever with thrombocytopenia syndrome (SFTS) was diagnosed using polymerase chain reaction. The patient developed impaired consciousness that worsened after 4 days. Magnetic resonance imaging of the head revealed a subdural hematoma in the occipital region with an uncertain onset time. As SFTS rarely causes intracranial hemorrhage, the associated risk factors are unknown. Clinicians may overlook potential intracranial hemorrhage in stuporous SFTS patients.

Abstract
Blue light (BL) is a fundamental cue for stomatal opening in both C3 and C4 plants. However, it is unknown whether crassulacean acid metabolism (CAM) plants open their stomata in response to BL. We investigated stomatal BL responses in the obligate CAM plants Kalanchoe pinnata and Kalanchoe daigremontiana that characteristically open their stomata at night and close them for part of the day, as contrasted with C3 and C4 plants. Stomata opened in response to weak BL superimposed on background red light in both intact leaves and detached epidermal peels of K. pinnata and K. daigremontiana. BL-dependent stomatal opening was completely inhibited by tautomycin and vanadate, which repress type 1 protein phosphatase and plasma membrane H+-ATPase, respectively. The plasma membrane H+-ATPase activator fusicoccin induced stomatal opening in the dark. Both BL and fusicoccin induced phosphorylation of the guard cell plasma membrane H+-ATPase in K. pinnata. These results indicate that BL-dependent stomatal opening occurs in the obligate CAM plants K. pinnata and K. daigremontiana independently of photosynthetic CO2 assimilation mode.

Abstract
We conducted this study to determine the short-term treatment outcomes of multidisciplinary approaches to chronic pain management for outpatients in Japan. We evaluated pain reduction and improvement in quality of life (QOL) after treatment. We analyzed 32 patients who had experienced intractable chronic pain for > 3 months. The patients received multidisciplinary therapeutic self-managed exercise instructions and then underwent evaluations 1 and 3 months after the treatment. We used the Pain Disability Short Form-36 (SF-36), Pain Catastrophizing Scale (PCS), and Pain Disability Assessment Scale (PDAS) to evaluate QOL. Although the pain levels were the same before and after the physical exercise program, the patients showed significant improvements in physical function on the SF-36 (48.5 vs. 54.5, 3 months vs. 1 month; p=0.0124), the magnification subscale on the PCS (6.8 vs. 5.9, 1 month vs. before; p=0.0164) and the PDAS (29.2 vs. 23.4, 3 months vs. before; p=0.0055). Chronic pain should be treated with a biopsychosocial approach, but time constraints and costs have limited the implementation of multidisciplinary and behavioral approaches to chronic pain management. Our findings demonstrate that clinical improvements are possible for patients with chronic pain, using multidisciplinary team resources widely available in Japanese clinical practice.

Abstract
Approximately, 10 million babies do not breathe immediately at birth and some of them require positive pressure ventilation. However, inappropriate and excessive tidal volume delivery could lead to lung injury in neonatal patients. We developed a respiratory function monitor which can monitor mask leak, expiratory tidal volume, respiratory rate, peak inspiratory pressure, and end-tidal CO2 on a real-time basis. A neonatal flow sensor was specially designed and was integrated with a small mainstream capnometer, cap-ONE. Usability was enhanced by using a tablet for the display of the monitored parameters. The basic performance evaluation using a neonatal training test lung shows that the respiratory function monitor effectively detects mask leak. The system may help healthcare providers to efficiently support neonatal patients start breathing.

Abstract
An 86-year-old male who was able to perform all activities of daily living (ADL) was diagnosed with hereditary hemorrhagic telangiectasia (HHT) at 70 years of age. Following his diagnosis, he had been receiving treatment at our hospital. After the sudden onset of a consciousness disorder, he was admitted to our hospital's emergency department with asterixis, a high serum ammonia level, and hepatic encephalopathy. After angiography, he was diagnosed with hepatic encephalopathy due to portal hepatic venous shunts. HHT is characterized by abnormal blood vessel construction and the formation of peripheral vasodilatation and shunt blood vessels. Although rare, portal hepatic venous shunts may sometimes cause hepatic encephalopathy. The extent of this shunt increases with age. As Japan is an increasingly aging society, the number of HHT patients with hepatic encephalopathy is likely to increase markedly in the future.

Abstract
Background: Isomaltodextrin (IMD) is a novel highly branched α-glucan and its function as a soluble dietary fiber is expected. Objective: The goal of this study was to evaluate the effects of IMD on postprandial glucose excursions in healthy people and to make the mechanism clear. Design: Twenty-nine subjects ingested a solution containing maltodextrin (MD) or sucrose with or without IMD. Fourteen subjects ingested a solution containing glucose with or without IMD. Blood glucose concentrations were then compared between the groups. Furthermore, in vitro digestion, inhibition of digestive enzymes, and glucose absorption tests were conducted. Results: IMD attenuated blood glucose elevation in the subjects with blood glucose excursions at the high end of normal following the ingestion of MD or sucrose or glucose alone. This effect of 5 g IMD was most clear. IMD was digested partially only by small intestinal mucosal enzymes, and maltase and isomaltase activities were weakly inhibited. Furthermore, IMD inhibited the transport of glucose from mucosal side to serosal side. Conclusions: IMD attenuated postprandial blood glucose, after the ingestion of MD or sucrose or glucose. As one of the mechanism, it was suggested that IMD inhibited the absorption of glucose on small intestinal mucosal membrane.

Abstract
An 88-year-old woman with a history of stomach perforation and lumbar compression fracture was admitted to our hospital with a chief complaint of continuous vomiting, which she had experienced since the previous day. She showed vomiting, spontaneous pain and tenderness from the epigastric fossa through the left flank. In addition, she had marked kyphosis. On a CT scan, although the fornix was located in the abdominal cavity, the antrum and body had escaped into the thoracic cavity. A large volume of gastric content was observed. The patient was diagnosed with upside-down stomach from gastric volvulus and a hiatal hernia. Although we recommended surgery, the patient and her family did not agree with it. Thus, conservative therapy was selected. The patient's symptoms showed a significant improvement after the placement of a nasogastric tube, fasting and fluid therapy. After stabilization, an endoscopic examination was performed. The release of the gastric volvulus was confirmed and the nasogastric tube was removed. We instructed the patient to perform postprandial repositioning, which was based on the running shape of the digestive tract with the goal of achieving the passage of food and preventing a relapse of vomiting. The patient was instructed to first place herself in the right lateral decubitus position and then the prone position after eating. There was no recurrence of vomiting after the patient resumed eating. She was therefore discharged from our hospital. Upside-down stomach is usually an indication for surgery. However, in elderly patients, the fixation of the stomach to the abdominal wall has been reported to occur after endoscopic reduction, and conservative treatment was thus selected in this case.We herein reported a case in which postprandial repositioning was used to treat upside-down stomach.

Abstract
OBJECTIVE The quality-adjusted life year, which is usually calculated from the health utility value, is now a standard measurement used in political decision-making in health. Although depression is the leading cause of decrement in health utility in general population, impact of comorbid depression among cancer patients has not been studied sufficiently. Therefore, this study aimed to measure the impact of depression on cancer patients' health utility score, according to the severity of depression. METHODS Impact of depression severity (measured by the Patient Health Questionnaire) on health utility score (measured by the EuroQoL-5 scale) was evaluated in a sample of 328 Japanese cancer patients, controlling for performance status, symptom burden, and demographic variables. RESULTS The patients with depression had significantly lower health utility value than those without depression (mean decrement = 0.14). Decrements in health utility of 0.13, 0.18, and 0.19 were observed for mild, moderate, and moderately severe to severe level of depression, respectively. The difference was significant between groups. Depression severity was a significant predictor for health utility (standardized coefficient beta = -0.25), which was comparable with physical symptom burden and performance status. Participants' age, gender, cancer stage, and comorbid illness were not significant. The model explained 37.9% of the variance. CONCLUSIONS Even mild level of depression caused clinically meaningful decrement in health utility value in cancer patients, which was comparable with decrements due to major physical complications of cancer. Influence of depression should be carefully investigated when interpreting the quality-adjusted life year among cancer patients. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
Stomatal movements are regulated by multiple environmental signals. Recent investigations indicate that photoperiodic flowering components, such as CRY, GI, CO, FT and TSF, are expressed in guard cells and positively affect stomatal opening in Arabidopsis thaliana. Here we show that SOC1, which encodes a MADS box transcription factor and integrates multiple flowering signals, also exerts a positive effect on stomatal opening. FLC encodes a potent repressor of FT and SOC1, and FRI acts as an activator of FLC. Thus, we examined stomatal phenotypes in FRI-Col, which contains an active FRI allele of accession Sf-2 by introgression. We found higher expression of FLC and lower expression of FT, SOC1 and TSF in guard cells from FRI-Col than in those from Col. Light-induced stomatal opening was significantly suppressed in FRI-Col. Interestingly, vernalization of FRI-Col partially restored light-induced stomatal opening, concomitant with a decrease of FLC and increase of FT, SOC1 and TSF. Furthermore, we observed the constitutive open-stomata phenotype in transgenic plants overexpressing SOC1-GFP (green fluorescent protein) in guard cells (SOC1-GFP overexpressor), and found that light-induced stomatal opening was significantly suppressed in a soc1 knockout mutant. RNA sequencing using epidermis from the SOC1-GFP overexpressor revealed that the expression levels of several genes involved in stomatal opening, such as BLUS1 and the plasma membrane H(+)-ATPases, were higher than those in background plants. From these results, we conclude that SOC1 is involved in the regulation of stomatal opening via transcriptional regulation in guard cells.

Abstract
In the outer periclinal cytoplasm of leaf epidermal cells of an aquatic angiosperm Vallisneria, blue light induces "chloroplast de-anchoring", a rapid decline in the resistance of chloroplasts against centrifugal force. Chloroplast de-anchoring is known induced within 1 min of irradiation with high-fluence-rate blue light specifically, preceding the commencement of chloroplasts migration toward the anticlinal cytoplasm. However, its regulatory mechanism has remained elusive, although pharmacological analysis suggested that a calcium release from intracellular calcium stores is necessary for the response. In search of the responsible photoreceptors, immunoblotting analysis using antibodies against phototropins demonstrated that cross-reactive polypeptides of 120-kDa exist in the plasma-membrane fraction prepared from the leaves. In vitro phosphorylation analysis revealed that 120-kDa polypeptides were phosphorylated by exposure to blue light in a fluence-dependent manner. The blue-light-induced phosphorylation activity was sensitive to a Ser/Thr kinase inhibitor, staurosporine, and unusually was retained at a high level for a long time in darkness. Furthermore, phototropin gene homologs (Vallisneria PHOTOTROPIN1 and PHOTOTROPIN2) expressed in leaves were isolated. We propose that calcium-regulated chloroplast de-anchoring, possibly mediated by phototropins, is an initial process of the blue-light-induced avoidance response of chloroplasts in Vallisneria.

Abstract
Depressive symptoms are common in patients with Alzheimer's disease (AD) and increase the caregiver burden. Many studies have reported dorsolateral prefrontal hypometabolism or hypoperfusion in AD patients with depressive symptoms, most of whom did not take acetylcholinesterase inhibitors (AChEI). It is not clear, however, whether a similar condition is present in patients taking AChEI medication. Fifty-seven consecutive AD patients taking AChEI were recruited at a memory clinic. Objective depressive symptoms were evaluated using the depression domain of the Neuropsychiatric Inventory (NPI-dep). All patients underwent brain single photon emission computed tomography (SPECT) with (99m)Tc-ethylcysteinate dimer, and the SPECT images were analyzed using the Statistical Parametric Mapping 8 program. No significant differences between groups with positive and negative NPI-dep scores were found with respect to age, sex, years of education, and cognitive function. Compared with patients with negative NPI-dep scores, patients with NPI-dep scores ≥1 showed significant hypoperfusion in the left middle frontal region. Our results indicate that the dorsolateral prefrontal area is significantly involved in the pathogenesis of depressive symptoms in AD patients being treated with AChEI. The area on the left side especially may be closely related to the depressive symptoms evaluated using the NPI.

Abstract
A 78-year-old woman was admitted to our hospital with lumbago. Her activities of daily living had previously been completely independent. However, she developed temporary chills in January 2009, that improved without treatment, but recurred on February 7, 2009 in association with left lumbago and loss of appetite. She was then referred to our hospital with a disturbance of consciousness and high fever on February 14. A blood test performed on admission revealed an elevated inflammatory response, coagulation disorder and low platelet count, and abdominal computed tomography demonstrated findings suggestive of pyogenic spondylitis. The patient was therefore admitted and treated with antibiotic therapy; however, she died on day 8 due to complications of disseminated intravascular coagulation. An autopsy showed isolated pulmonary valve endocarditis. The patient's history was later found to include regular dental treatment, and the same Streptococcus group G was detected in cultures of the sputum, blood and vegetation. It is important to interview patients regarding their history of dental treatment, particularly elderly individuals with fever of unknown origin.

Abstract
To elucidate the molecular mechanisms of stomatal opening and closure, we performed a genetic screen using infrared thermography to isolate stomatal aperture mutants. We identified a mutant designated low temperature with open-stomata 1 (lost1), which exhibited reduced leaf temperature, wider stomatal aperture, and a pale green phenotype. Map-based analysis of the LOST1 locus revealed that the lost1 mutant resulted from a missense mutation in the Mg-chelatase I subunit 1 (CHLI1) gene, which encodes a subunit of the Mg-chelatase complex involved in chlorophyll synthesis. Transformation of the wild-type CHLI1 gene into lost1 complemented all lost1 phenotypes. Stomata in lost1 exhibited a partial ABA-insensitive phenotype similar to that of rtl1, a Mg-chelatase H subunit missense mutant. The Mg-protoporphyrin IX methyltransferase (CHLM) gene encodes a subsequent enzyme in the chlorophyll synthesis pathway. We examined stomatal movement in a CHLM knockdown mutant, chlm, and found that it also exhibited an ABA-insensitive phenotype. However, lost1 and chlm seedlings all showed normal expression of ABA-induced genes, such as RAB18 and RD29B, in response to ABA. These results suggest that the chlorophyll synthesis enzymes, Mg-chelatase complex and CHLM, specifically affect ABA signaling in the control of stomatal aperture and have no effect on ABA-induced gene expression.

Abstract
We examined the dietary effects of cyclic nigerosylnigerose (CNN), a dietary indigestible oligosaccharide with four D-glucopyranosyl residues linked by alternating alpha-(1-->3)- and alpha-(1-->6) glucosidic linkages, on the intestinal immune function of mice, and the effects were compared with those of alpha-(1-->3)-linked oligosaccharide (nigerooligosaccharides, NOS) or alpha-(1-->6)-linked oligosaccharide (isomaltooligosaccharides, IMO). BALB/c mice were fed with 1-5% CNN, 5% IMO, or 12.5% NOS for 4 weeks, and the intestinal mucosal immune responses were determined. In the 1-5% CNN fed groups, the amounts of IgA in feces increased significantly. In addition, IgA, transforming growth factor-beta1 (TGF-beta1), and interleukin-6 (IL-6) secretion by Peyer's patch (PP) cells were enhanced in CNN fed mice. In the 5% CNN group, pH in the cecum decreased, and the amounts of lactic acid and butyric acid increased. These findings were not observed in the NOS- or IMO-fed group of mice. They suggest that CNN supplementation changes the intestinal environment of microflora and indirectly enhances the immune function in the gut.

Abstract
AIM Pseudogout is an important causative disease of febrile illness in elderly patients. We experienced cases of pseudogout during or after the progression of inflammatory disease. METHODS We investigated 14 patients with pseudogout admitted to the Department of Geriatric Medicine at Kyorin University Hospital. Seven patients who developed inflammatory disease prior to the onset of pseudogout are described in greater detail. RESULTS The affected joint was the knee joint in 12 of 14 cases. Other joints were affected in four cases, and four patients had more than two affected joints in this series. Clear joint cartilage calcification was noted on X-rays in nine of 14 cases, and CPPD crystals were detected in two patients treated with joint puncture. NSAIDs were administered in all cases for treatment. Seven patients had a preceding inflammatory disease, with infectious disease in all cases. Repeat elevation of temperature and inflammatory reactions were seen in seven cases, with progression to bimodal disease in two cases. The average duration of antimicrobial use was 11 days. In three cases, the average duration of antimicrobial use was 33 days, and two or more antimicrobials were used for long-term treatment. CONCLUSIONS Pseudogout appears as delayed infective disease and fever of unknown origin in the elderly. This condition may easily be overlooked until joint symptoms become apparent. It is extremely important to keep pseudogout in mind as a differential diagnosis of thermogenesis in elderly patients.

Abstract
FLOWERING LOCUS T (FT) is the major regulatory component controlling photoperiodic floral transition. It is expressed in guard cells and affects blue light-induced stomatal opening induced by the blue-light receptor phototropins phot1 and phot2. Roles for other flowering regulators in stomatal opening have yet to be determined. We show in Arabidopsis (Arabidopsis thaliana) that TWIN SISTER OF FT (TSF), CONSTANS (CO), and GIGANTEA (GI) provide a positive effect on stomatal opening. TSF, which is the closest homolog of FT, was transcribed in guard cells, and light-induced stomatal opening was repressed in tsf-1, a T-DNA insertion mutant of TSF. Overexpression of TSF in a phot1 phot2 mutant background gave a constitutive open-stomata phenotype. Then, we examined whether CO and GI, which are upstream regulators of FT and TSF in photoperiodic flowering, are involved in stomatal opening. Similar to TSF, light-induced stomatal opening was suppressed in the GI and CO mutants gi-1 and co-1. A constitutive open-stomata phenotype was observed in GI and CO overexpressors with accompanying changes in the transcription of both FT and TSF. In photoperiodic flowering, photoperiod is sensed by photoreceptors such as the cryptochromes cry1 and cry2. We examined stomatal phenotypes in a cry1 cry2 mutant and in CRY2 overexpressors. Light-induced stomatal opening was suppressed in cry1 cry2, and the transcription of FT and TSF was down-regulated. In contrast, the stomata in CRY2 overexpressors opened even in the dark, and FT and TSF transcription was up-regulated. We conclude that the photoperiodic flowering components TSF, GI, and CO positively affect stomatal opening.

The Mg-chelatase H subunit (CHLH) has been shown to mediate chlorophyll biosynthesis, as well as plastid-to-nucleus and abscisic acid (ABA)-mediated signaling. A recent study using a novel CHLH mutant, rtl1, indicated that CHLH specifically affects ABA-induced stomatal closure, but also that CHLH did not serve as an ABA receptor in Arabidopsis thaliana. However, the molecular mechanism by which CHLH engages in ABA-mediated signaling in guard cells remains largely unknown. In the present study, we examined CHLH function in guard cells and explored whether CHLH expression might influence stomatal aperture. Incubation of rtl1 guard cell protoplasts with ABA induced expression of the ABA-responsive genes RAB18 and RD29B, as also observed in wild-type (WT) cells, indicating that CHLH did not affect the expression of ABA-responsive genes. Earlier, ABA was reported to inhibit blue light (BL)-mediated stomatal opening, at least in part through dephosphorylating/inhibiting guard cell H(+)-ATPase (which drives opening). Therefore, we immunohistochemically examined the phosphorylation status of guard cell H(+)-ATPase. Notably, ABA inhibition of BL-induced phosphorylation of H(+)-ATPase was impaired in rtl1 cells, suggesting that CHLH influences not only ABA-induced stomatal closure but also inhibition of BL-mediated stomatal opening by ABA. Next, we generated CHLH-GFP-overexpressing plants using CER6 promoter, which induces gene expression in the epidermis including guard cells. CHLH-transgenic plants exhibited a closed stomata phenotype even when brightly illuminated. Moreover, plant growth experiments conducted under water-deficient conditions showed that CHLH transgenic plants were more tolerant of drought than WT plants. In summary, we show that CHLH is involved in the regulation of stomatal aperture in response to ABA, but not in ABA-induced gene expression, and that manipulation of stomatal aperture via overexpression of CHLH in guard cells improves plant drought tolerance.

Abstract
We investigated the roles of the blue light receptors phototropins (phot1 and phot2) and ROOT PHOTOTROPISM 2 (RPT2) in leaf positioning and flattening, and plant growth under weak, moderate and strong white light (10, 25 and 70 µmol m(-2 )s(-1)). RPT2 mediated leaf positioning and flattening, and enhanced plant growth in a phot1-dependent manner. Under weak light, phot1 alone controls these responses. Under moderate and strong light, both phot1 and phot2 affect the responses. These results indicate that plants utilize a wide range of light intensities through phot1 and phot2 to optimize plant growth. The rpt2 single mutant generally exhibited phenotypes that resembled those of the phot1 phot2 double mutant. To our surprise, when the PHOT1 gene was disrupted in the rpt2 mutant, the resulting phot1 rpt2 double mutant showed the morphology of the wild-type plant under strong light, and additional disruption of PHOT2 in the double mutant abolished this recovery. This suggested that phot2 may function in the absence of phot1 and bypass RPT2 to transmit the signal to downstream elements. Expression and light-induced autophosphorylation of phot2 were not affected in the rpt2 mutant. We conclude that RPT2 mediates leaf flattening and positioning in a phot1-dependent manner, and that phot1 may inhibit the phot2 signaling pathways. We discuss the functional role of RPT2 in phototropin signaling.

Abstract
The plasma membrane H (+) -ATPase provides the driving force for solute transport via an electrochemical gradient of H (+) across the plasma membrane, and regulates pH homeostasis and membrane potential in plant cells. However, the plasma membrane H (+) -ATPase in non-vascular plant bryophyte is largely unknown. Here, we show that the moss Physcomitrella patens, which is known as a model bryophyte, expresses both the penultimate Thr-containing H (+) -ATPase (pT H (+) -ATPase) and non-pT H (+) -ATPase as in the green algae, and that pT H (+) -ATPase is regulated by phosphorylation of its penultimate Thr. A search in the P. patens genome database revealed seven H (+) -ATPase genes, designated PpHA (Physcomitrella patens H (+) -ATPase). Six isoforms are the pT H (+) -ATPase; a remaining isoform is non-pT H (+) -ATPase. An apparent 95-kD protein was recognized by anti-H (+) -ATPase antibodies against an isoform of Arabidopsis thaliana and was phosphorylated on the penultimate Thr in response to a fungal toxin fusicoccin and light in protonemata, indicating that the 95-kD protein contains pT H (+) -ATPase. Furthermore, we could not detect the pT H (+) -ATPase in the charophyte alga Chara braunii, which is the closest relative of the land plants, by immunological methods. These results strongly suggest the pT H (+) -ATPase most likely appeared for the first time in bryophyte.

Abstract
The plasma membrane H(+)-ATPase generates an electrochemical gradient of H(+) across the plasma membrane that provides the driving force for solute transport and regulates pH homeostasis and membrane potential in plant cells. Recent studies have demonstrated that phosphorylation of the penultimate threonine in H(+)-ATPase and subsequent binding of a 14-3-3 protein is the major common activation mechanism for H(+)-ATPase in vascular plants. However, there is very little information on the plasma membrane H(+)-ATPase in nonvascular plant bryophytes. Here, we show that the liverwort Marchantia polymorpha, which is the most basal lineage of extant land plants, expresses both the penultimate threonine-containing H(+)-ATPase (pT H(+)-ATPase) and non-penultimate threonine-containing H(+)-ATPase (non-pT H(+)-ATPase) as in the green algae and that pT H(+)-ATPase is regulated by phosphorylation of its penultimate threonine. A search in the expressed sequence tag database of M. polymorpha revealed eight H(+)-ATPase genes, designated MpHA (for M. polymorpha H(+)-ATPase). Four isoforms are the pT H(+)-ATPase; the remaining isoforms are non-pT H(+)-ATPase. An apparent 95-kD protein was recognized by anti-H(+)-ATPase antibodies against an Arabidopsis (Arabidopsis thaliana) isoform and was phosphorylated on the penultimate threonine in response to the fungal toxin fusicoccin in thalli, indicating that the 95-kD protein contains pT H(+)-ATPase. Furthermore, we found that the pT H(+)-ATPase in thalli is phosphorylated in response to light, sucrose, and osmotic shock and that light-induced phosphorylation depends on photosynthesis. Our results define physiological signals for the regulation of pT H(+)-ATPase in the liverwort M. polymorpha, which is one of the earliest plants to acquire pT H(+)-ATPase.

Abstract
We report the case of a 48-year-old man with adult-onset adrenoleukodystrophy (ALD) who developed dementia with subacute onset. He was abulic, indifferent to his surroundings, and without insight with regards to his own disease. An elevated plasma very long chain fatty acid level and a novel point mutation IVS3+2t>g in the ABCD1 gene confirmed the diagnosis of ALD. Diffusion-weighted MRI revealed a high intensity area in the white matter of the frontal lobes. Severe brain hypoperfusion in the frontal lobes was revealed. We believe that this is a rare case of adult-onset adrenoleukodystrophy with predominant frontal lobe dysfunction.

Abstract
Mg-chelatase H subunit (CHLH) is a multifunctional protein involved in chlorophyll synthesis, plastid-to-nucleus retrograde signaling, and ABA perception. However, whether CHLH acts as an actual ABA receptor remains controversial. Here we present evidence that CHLH affects ABA signaling in stomatal guard cells but is not itself an ABA receptor. We screened ethyl methanesulfonate-treated Arabidopsis thaliana plants with a focus on stomatal aperture-dependent water loss in detached leaves and isolated a rapid transpiration in detached leaves 1 (rtl1) mutant that we identified as a novel missense mutant of CHLH. The rtl1 and CHLH RNAi plants showed phenotypes in which stomatal movements were insensitive to ABA, while the rtl1 phenotype showed normal sensitivity to ABA with respect to seed germination and root growth. ABA-binding analyses using (3)H-labeled ABA revealed that recombinant CHLH did not bind ABA, but recombinant pyrabactin resistance 1, a reliable ABA receptor used as a control, showed specific binding. Moreover, we found that the rtl1 mutant showed ABA-induced stomatal closure when a high concentration of extracellular Ca(2+) was present and that a knockout mutant of Mg-chelatase I subunit (chli1) showed the same ABA-insensitive phenotype as rtl1. These results suggest that the Mg-chelatase complex as a whole affects the ABA-signaling pathway for stomatal movements.

Abstract
Phototropins (phot1 and phot2) are autophosphorylating blue-light receptor kinases that mediate blue-light responses such as phototropism, chloroplast accumulation, and stomatal opening in Arabidopsis (Arabidopsis thaliana). Only phot2 induces the chloroplast avoidance response under strong blue light. The serine (Ser) residues of the kinase activation loop in phot1 are autophosphorylated by blue light, and autophosphorylation is essential for the phot1-mediated responses. However, the role of autophosphorylation in phot2 remains to be determined. In this study, we substituted the conserved residues of Ser-761 and Ser-763 with alanine (S761A S763A) in the phot2 activation loop and analyzed their function by investigating the phot2-mediated responses after the transformation of phot1 phot2 double mutant with this mutant phot2 gene. Transgenic plants expressing the mutant phot2 protein exhibited impaired responses in chloroplast movement, stomatal opening, phototropic bending, leaf flattening, and plant growth; and those expressing phot2 with S761D S763D mutations showed the normal responses. Substitution of both Ser-761 and Ser-763 with alanine in phot2 did not significantly affect the kinase activity in planta. From these results, we conclude that phosphorylation of Ser-761 and Ser-763 in the activation loop may be a common primary step for phot2-mediated responses.

Abstract
Phototropins are plant-specific light-activated receptor kinases that regulate diverse blue-light-induced responses, and serve to optimize plant growth under various light environments. Phototropins undergo autophosphorylation as an essential step for their signaling and induce a variety of tissue-specific or organ-specific responses, but the divergent mechanisms for these responses are unknown. It is most likely that the phototropins generate a specific output after the event of autophosphorylation. In this report, we will review the common steps of phototropin signaling and the numerous interactive proteins of phototropins, which may act as signal transducers for the diverse responses. We also describe the phototropin-mediated signaling process of stomatal guard cells and its crosstalk with abscisic acid signaling.

Abstract
In Arabidopsis (Arabidopsis thaliana), the blue light photoreceptor phototropins (phot1 and phot2) fine-tune the photosynthetic status of the plant by controlling several important adaptive processes in response to environmental light variations. These processes include stem and petiole phototropism (leaf positioning), leaf flattening, stomatal opening, and chloroplast movements. The PHYTOCHROME KINASE SUBSTRATE (PKS) protein family comprises four members in Arabidopsis (PKS1-PKS4). PKS1 is a novel phot1 signaling element during phototropism, as it interacts with phot1 and the important signaling element NONPHOTOTROPIC HYPOCOTYL3 (NPH3) and is required for normal phot1-mediated phototropism. In this study, we have analyzed more globally the role of three PKS members (PKS1, PKS2, and PKS4). Systematic analysis of mutants reveals that PKS2 (and to a lesser extent PKS1) act in the same subset of phototropin-controlled responses as NPH3, namely leaf flattening and positioning. PKS1, PKS2, and NPH3 coimmunoprecipitate with both phot1-green fluorescent protein and phot2-green fluorescent protein in leaf extracts. Genetic experiments position PKS2 within phot1 and phot2 pathways controlling leaf positioning and leaf flattening, respectively. NPH3 can act in both phot1 and phot2 pathways, and synergistic interactions observed between pks2 and nph3 mutants suggest complementary roles of PKS2 and NPH3 during phototropin signaling. Finally, several observations further suggest that PKS2 may regulate leaf flattening and positioning by controlling auxin homeostasis. Together with previous findings, our results indicate that the PKS proteins represent an important family of phototropin signaling proteins.

Abstract
A 79-year-old woman attended the Center for Comprehensive Care of Memory Disorders at the Kyorin University Hospital in 2006 due to forgetfulness. Her initial diagnosis was vascular dementia. In 2007, her cognition declined gradually. Then, impaired verbal fluency and stuttering, the symptoms of non-fluent aphasia, were presented. Thereafter, 5 mg/day donepezil hydrochloride was prescribed. She later suffered type II respiratory failure. Needle electromyography revealed denervation of lower motor neurons. This led to the diagnosis of frontotemporal dementia with motor neuron disease. Interestingly, before developing type II respiratory failure, cognitive decline and non-fluent aphasia occurred in this case.

Abstract
We directly determine the experimental photonic band dispersion structure of waveguiding modes under the light line in a two-dimensional photonic crystal (2D PhC) waveguide by using angle-resolved attenuated total reflection spectroscopy. Resonance coupling between the external evanescent wave from total reflection within the prism and the waveguiding modes in the 2D PhC provides clear information on individual band components by resolving the angle (i.e., wave vector k) and photon energy. The experimentally determined photonic band structure, which is essential for understanding the novel light propagation properties of PhC systems with many degrees of freedom, agrees well with the band structure predicted by theory. Furthermore, we demonstrate the accuracy and suitability of this method by analyzing field distribution and eigen-photon-energy calculations for a model structure identical to the experimental arrangement of the prism and sample structure.

Abstract
Appropriate leaf positioning is essential for optimizing photosynthesis and plant growth. However, it has not been elucidated how green leaves reach and maintain their position for capturing light. We show here the regulation of leaf positioning under blue light stimuli. When 1-week-old Arabidopsis seedlings grown under white light were transferred to red light (25 micromol m(-2) s(-1)) for 5 d, new petioles that appeared were almost horizontal and their leaves were curled and slanted downward. However, when a weak blue light from above (0.1 micromol m(-2) s(-1)) was superimposed on red light, the new petioles grew obliquely upward and the leaves were flat and horizontal. The leaf positioning required both phototropin1 (phot1) and nonphototropic hypocotyl 3 (NPH3), and resulted in enhanced plant growth. In an nph3 mutant, neither optimal leaf positioning nor leaf flattening by blue light was found, and blue light-induced growth enhancement was drastically reduced. When blue light was increased from 0.1 to 5 micromol m(-2) s(-1), normal leaf positioning and leaf flattening were induced in both phot1 and nph3 mutants, suggesting that phot2 signaling became functional and that the signaling was independent of phot1 and NPH3 in these responses. When plants were irradiated with blue light (0.1 micromol m(-2) s(-1)) from the side and red light from above, the new leaves became oriented toward the source of blue light. When we transferred these plants to both blue light and red light from above, the leaf surface changed its orientation to the new blue light source within a few hours, whereas the petioles initially were unchanged but then gradually rotated, suggesting the plasticity of leaf positioning in response to blue light. We showed the tissue expression of NPH3 and its plasma membrane localization via the coiled-coil domain and the C-terminal region. We conclude that NPH3-mediated phototropin signaling optimizes the efficiency of light perception by inducing both optimal leaf positioning and leaf flattening, and enhances plant growth.

Abstract
BACKGROUND It has been reported that elderly outpatients take at least 6 different kinds of medication. PURPOSE To know which formula will best predict creatinine clearance, because 24-hour urine collection is difficult for elderly outpatients. PATIENTS AND METHODS We compared four types of formulae (Cockcroft and Gault, Yasuda, Orita, Walser) to estimate creatinine clearance using serum creatinine of 143 elderly inpatients (73 men, 70 women, mean age 82.9 +/- 8.6 years old) including 67 extremely elderly people with various underlying diseases. RESULT The formula of Cockcroft and Gault showed the best correlation with creatinine clearance in the extremely elderly subjects (r = 0.74) as well as in people under 85 years (r = 0.76). However, the estimated values of the extremely elderly women were lower than actual creatinine clearance. CONCLUSION The formula of Cockcroft and Gault is the best predictive equation of creatinine clearance, except in the extremely elderly women.
