Abstract
Root water uptake depth and its temporal variation are important determinants of tree mortality, resource partitioning and drought resistance; however, their effects on tropical trees remain poorly understood. In this study, we investigated interspecific differences in water uptake depth and its temporal variation using stable isotope analysis and examined the relationships between water uptake depth and aboveground traits in a humid aseasonal tropical rainforest in Borneo. Species-specific differences in water uptake depth were examined for six dominant dipterocarp species. Temporal variation in water uptake depth for various canopy trees was assessed in three periods with different soil moisture conditions. We then examined the relationships between water uptake depth and aboveground traits including wood density, maximum tree height, flowering frequency and growth rate. Dipterocarpus globosus appeared to be more reliant on deep water resources than the other dipterocarp species. Water uptake from the soil layers varied among the three sampling periods. Trees generally utilized deeper soil water during the second driest sampling period, when temperatures were lowest. During the driest and wettest sampling periods, species with higher flowering frequencies tended to preferentially uptake deep soil water. These results suggest that low temperature and soil moisture promote increased deep soil water uptake in the study region. Dynamic relationships between water uptake patterns and aboveground tree traits may be related to resource partitioning among co-existing species.

Abstract
Mixotrophic plants obtain carbon by their own photosynthetic activity and from their root-associated mycorrhizal fungi. Mixotrophy is deemed a pre-adaptation for evolution of mycoheterotrophic nutrition, where plants fully depend on fungi and lose their photosynthetic activity. The aim of this study was to clarify mycorrhizal dependency and heterotrophy level in various phenotypes of mixotrophic Pyrola japonica (Ericaceae), encompassing green individuals, rare achlorophyllous variants (albinos) and a form with minute leaves, P. japonica f. subaphylla. These three phenotypes were collected in two Japanese forests. Phylogenetic analysis of both plants and mycorrhizal fungi was conducted based on DNA barcoding. Enrichment in 13C among organs (leaves, stems and roots) of the phenotypes with reference plants and fungal fruitbodies were compared by measuring stable carbon isotopic ratio. All plants were placed in the same clade, with f. subaphylla as a separate subclade. Leaf 13C abundances of albinos were congruent with a fully mycoheterotrophic nutrition, suggesting that green P. japonica leaves are 36.8% heterotrophic, while rhizomes are 74.0% heterotrophic. There were no significant differences in δ13C values among organs in both albino P. japonica and P. japonica f. subaphylla, suggesting full and high mycoheterotrophic nutrition, respectively. Among 55 molecular operational taxonomic units (OTUs) detected as symbionts, the genus Russula was the most abundant in each phenotype and its dominance was significantly higher in albino P. japonica and P. japonica f. subaphylla. Russula spp. detected in P. japonica f. subaphylla showed higher dissimilarity with other phenotypes. These results suggest that P. japonica sensu lato is prone to evolve mycoheterotrophic variants, in a process that changes its mycorrhizal preferences, especially towards the genus Russula for which this species has a marked preference.

Abstract
SETTING AND OBJECTIVE Several studies have found a significant association between tuberculosis (TB) and spatial factors. We wished to determine the effect of host-related factors and spatial factors associated with an increased risk of TB, and to assess spatial clustering. DESIGN A hospital-based case-control study using medical records was conducted. A total of 103 age- and sex-matched TB patients (cases) and 299 patients without TB (controls) were recruited from January 2000 to December 2016 in a hospital in Nagata, Kobe, Japan. Logistic regression, kernel density estimation, Cross L function and a Poisson regression model were applied. RESULTS The epidemiological factors associated with TB were being a health care worker (OR 10.1) and lower serum albumin level (OR 0.5). Spatial analyses revealed TB to be positively associated with population density (risk ratio [RR] 32.1), the proportion of single households (RR -1.85) and persons aged 65 years (RR 2.65) and one spatial clustering. CONCLUSION Our findings could help in the identification of high TB risk individuals and districts.

Abstract
BACKGROUND We have been trying to produce scaffold-free structures for airway regeneration using a bio-3D-printer with spheroids, to avoid scaffold-associated risks such as infection. Previous studies have shown that human umbilical vein endothelial cells (HUVECs) play an important role in such structures, but HUVECs cannot be isolated from adult humans. The aim of this study was to identify alternatives to HUVECs for use in scaffold-free structures. METHODS Three types of structure were compared, made of chondrocytes and mesenchymal stem cells with HUVECs, human lung microvascular endothelial cells (HMVEC-Ls), and induced pluripotent stem cell (iPSC)-derived endothelial cells. RESULTS No significant difference in tensile strength was observed between the three groups. Histologically, some small capillary-like tube formations comprising CD31-positive cells were observed in all groups. The number and diameters of such formations were significantly lower in the iPSC-derived endothelial cell group than in other groups. Glycosaminoglycan content was significantly lower in the iPSC-derived endothelial cell group than in the HUVEC group, while no significant difference was observed between the HUVEC and HMVEC-L groups. CONCLUSIONS HMVEC-Ls can replace HUVECs as a cell source for scaffold-free trachea-like structures. However, some limitations were associated with iPSC-derived endothelial cells.

Abstract
To evaluate water use and the supporting water source of a tropical rainforest, a 4-year assessment of evapotranspiration (ET) was conducted in Pasoh Forest Reserve, a lowland dipterocarp forest in Peninsular Malaysia. The eddy covariance method and isotope signals of rain, plant, soil, and stream waters were used to determine forest water sources under different moisture conditions. Four sampling events were conducted to collect soil and plant twig samples in wet, moderate, dry, and very dry conditions for the identification of isotopic signals. Annual ET from 2012 to 2015 was quite stable with an average of 1,182 ± 26 mm, and a substantial daily ET was observed even during drought periods, although some decline was observed, corresponding with volumetric soil water content. During the wet period, water for ET was supplied from the surface soil layer between 0 and 0.5 m, whereas in the dry period, approximately 50% to 90% was supplied from the deeper soil layer below 0.5-m depth, originating from water precipitated several months previously at this forest. Isotope signatures demonstrated that the water sources of the plants, soil, and stream were all different. Water in plants was often different from soil water, probably because plant water came from a different source than water that was strongly bound to the soil particles. Plants showed no preference for soil depth with their size, whereas the existence of storage water in the xylem was suggested. The evapotranspiration at this forest is balanced and maintained using most of the available water sources except for a proportion of rapid response run-off.

Abstract
PURPOSE To evaluate the inter-device agreement among the Goldmann applanation tonometer (GAT), iCare and Icare PRO rebound tonometers, non-contact tonometer (NCT), and Tonopen XL tonometer. METHODS Sixty healthy elderly subjects were enrolled. The intraocular pressure (IOP) in each subject's right eye was measured thrice using each of the five tonometers. Intra-device agreement was evaluated by calculating intraclass correlation coefficients (ICCs). Inter-device agreement was evaluated by ICC and Bland-Altman analyses. RESULTS ICCs for intra-device agreement for each tonometer were >0.8. IOP as measured by iCare (mean ± SD, 11.6 ± 2.5 mmHg) was significantly lower (p < 0.05) than that measured by GAT (14.0 ± 2.8 mmHg), NCT (13.6 ± 2.5 mmHg), Tonopen XL (13.7 ± 4.1 mmHg), and Icare PRO (12.6 ± 2.2 mmHg; Bonferroni test). There was no significant difference in mean IOP among GAT, NCT, and Tonopen XL. Regarding inter-device agreement, ICC was lower between Tonopen XL and other tonometers (all ICCs < 0.4). However, ICCs of GAT, iCare, Icare PRO, and NCT showed good agreement (0.576-0.700). The Bland-Altman analysis revealed that the width of the 95% limits of agreement was larger between the Tonopen XL and the other tonometers ranged from 14.94 to 16.47 mmHg. Among the other tonometers, however, the widths of 95% limits of agreement ranged from 7.91 to 9.24 mmHg. CONCLUSION There was good inter-device agreement among GAT, rebound tonometers, and NCT. Tonopen XL shows the worst agreement with the other tonometers; therefore, we should pay attention to its' respective IOP.

Abstract
A woman ingested a dose of sublimate (approximately 0.9 g) in an attempted suicide. She survived and recovered in response to a combination of therapies including chelate (BAL) therapy, plasma exchange, haemodialysis and peritoneal dialysis. Serum inorganic mercury concentration, urinary inorganic mercury excretion and hair inorganic and organic mercury and selenium concentrations, along the length from the scalp to the distal part, were measured. Longitudinal analysis of hair, revealed a peak in inorganic mercury corresponding to the time of mercury ingestion. Organic mercury and selenium in the hair had different patterns of longitudinal variation from that of inorganic mercury. The biological half-life (23.5 d) of serum inorganic mercury levels was in good agreement with values previously reported in the literature.

Abstract
Administration of large doses of vitamin D2 brought about a marked increase of 25-hydroxyvitamin D in both the patients with vitamin D dependency and hypophosphatemic vitamin D-resistant rickets. During the administration of vitamin D2, increment of 1,25-dihydroxyvitamin D was marked in hypophosphatemic vitamin D-resistant rickets, but far smaller in vitamin D dependency. In the latter, however, the 1,25-dihydroxyvitamin D reached the level close to the normal adult values. 1 alpha-hydroxyvitamin D3 was found 50 approximately 100 times as effective as vitamin D2 in 2 patients with vitamin D dependency (optimum maintenance dose: 0.05 micrograms/kg/day). It was concluded that 1 alpha-hydroxylation in the renal tubules is markedly defective in the patients with vitamin D dependency, but that a large dose of vitamin D2 is able to cause a definite increase in serum concentration of 1,25-dihydroxyvitamin D resulting in improvement of the rickets.

Abstract
Purpose We investigated the incidence of prostaglandin-associated periorbitopathy (PAP) in subjects with glaucoma treated with latanoprost ophthalmic solution. Subjects and methods One eye and the forehead in 22 subjects were evaluated. All patients had used latanoprost for more than 1 year (range, 12 to 45 months; mean, 26.0 months) and were prostaglandin F2α analogue treatment-naïve. Digital photographs of the subjects obtained before latanoprost therapy and at the last examination were compared retrospectively. Four signs of PAP (deepening of the upper eyelid sulcus (DUES), upper eyelid ptosis, flattening of the lower eyelid bags, and inferior scleral show) and supplemental side effects around the eyelids (eyelash growth, poliosis, and eyelid pigmentation) were judged to be negative or positive by three independent observers. If the observers unanimously rated a sign as positive, the result was defined as positive. Results Twelve subjects (54.5%) had no apparent signs. Three subjects were judged to have DUES (13.6%), and two subjects each were judged to have flattening of the lower eyelid bags and eyelid pigmentation (9.0%). The other signs were judged as positive in only one subject each, respectively (4.5%). A univariate logistic regression analysis showed no significant associations between any of the signs and age, sex, or the duration of therapy. Conclusion Latanoprost induced DUES, upper eyelid ptosis, flattening of the lower eyelid bags, inferior scleral show, and supplemental side effects around the eyelids; however, the rates of such occurrence might be relatively low.

Abstract
Background Deepening of the upper eyelid sulcus (DUES) is a common complication of prostaglandin F2α analog treatment, which causes cosmetic problems. However, identifying this condition using photographs is difficult due to such problems as the camera flash effects, blepharoptosis or wide-open eyes. Purpose We investigated the association between a DUES-like appearance and wide-open eyes regarding the presence of wide-open eyes as a cause for overestimating the incidence of DUES. Subjects and Methods One eye and the forehead in 100 subjects (31 younger subjects, 30 older subjects and 39 patients with blepharoptosis) were evaluated in the present study. Digital photographs of the subjects with natural open and wide-open eyes were taken with a flash. Five signs (a puffy eyelid, the presence/absence of the upper eyelid sulcus (UES), wrinkles on the forehead with natural open eyes and an increase in the number of wrinkles on the forehead and a DUES-like appearance with wide-open eyes) were judged to be negative or positive by three independent observers. Univariate and multivariate logistic regression analyses were performed to determine the independent predictor(s) of a DUES-like appearance with wide-open eyes. Results Fourteen subjects (four young, three old and seven subjects with blepharoptosis) were judged to have a DUES-like appearance with wide-open eyes (14%). The only predictive factor was the presence of UES in the patients with natural open eyes (odds ratio = 17.244, 95% confidence interval: 3.447–86.270, P<0.001). Among the 12 UES-positive subjects, six (50%) exhibited a DUES-like appearance with wide-open eyes. Conclusions The presence of wide-open eyes can thus cause a DUES-like appearance. Blepharoptosis itself is not a predictive factor; however, care should be taken not to overestimate the incidence of DUES, especially in patients with UES with natural open eyes, as a DUES-like appearance can be caused by wide-open eyes, even in treatment-naïve patients.

Abstract
Clinical use of bone marrow mesenchymal stem cells (BMMSCs) holds great promise for regenerative medicine in intractable lung diseases, such as lung fibrosis or acute respiratory distress syndrome. However, a severe obstacle to the clinical application of BMMSC transplantation is the time-consuming, laborious processes required for cell culture. In order to evaluate the clinical applicability of BMMSC transplantation, we tested whether engraftment of minimally cultured BMMSCs ameliorates progressive fibrotic lung injury. Differences between murine BMMSCs cultured for 2 h (2-h adherent BMMSCs) and conventionally (9-day) cultured BMMSCs were examined in vitro. The effects of grafting either type of BMMSCs on fibrotic lung injury were then assessed by transfer experiments in a murine bleomycin-induced lung fibrosis model, in which donor cells were administered 3 days after challenge. 2-h adherent BMMSCs were smaller, less granular, possessed higher proliferative capacity and expressed higher levels of several stem cell markers and chemokine receptors than 9-day cultured BMMSCs, but lower type I procollagen, alpha-smooth muscle actin, tumour necrosis factor-beta and oncogenic transcription factor c-Myc, suggesting that they may be advantageous for cell-based therapy compared with 9-day cultured BMMSCs. Grafting 2-h adherent BMMSCs ameliorated inflammatory and fibrotic lung disorders, and reduced mortality equally well or better than 9-day cultured BMMSCs. Minimally cultured BMMSCs can substitute for conventionally cultured BMMSCs and will be a promising cell source for the treatment of acute fibrotic lung injury.

Abstract
We observed diurnal and seasonal patterns of leaf-scale gas exchange within the crown of a Dipterocarpus sublamellatus Foxw. tree growing in a lowland dipterocarp forest at Pasoh, Peninsular Malaysia. Observations were carried out nine times over 6 years, from September 2002 to December 2007. Observation periods included both wet and mild-dry periods, and natural and saturated photosynthetic photon flux density (PPFD) light conditions. In situ measurements of the diurnal change in net photosynthetic rate and in stomatal conductance were carried out on canopy leaves of a 40-m-tall D. sublamellatus tree, which was accessed from a canopy corridor. A diurnal change in electron transport rate was observed under saturated PPFD conditions. The maximum net assimilation rate was approximately 10 micromol m(-2) s(-1). There was a clear inhibition of the net assimilation rate coupled with stomatal closure after late morning and this inhibition occurred year-round. Although the electron transport rate decreased alongside this inhibition, it sometimes followed on. Numerical analysis showed that the main factor in the inhibition of the net assimilation rate was patchy bimodal stomatal closure, which occurred in both mild-dry and wet periods. The midday depression occurred year-round, though there are fluctuations in soil moisture during the mild-dry and wet periods. The magnitude of the inhibition was not related to soil water content but was related to vapor pressure deficit (VPD): that is, whether the days were sunny and hot or cloudy and cool. On cloudy, cool days in the wet period, the net photosynthesis was only moderately inhibited, but it still decreased in the afternoon and was coupled with patchy stomatal closure, even in quite moderate VPD, leaf temperature and PPFD conditions. Our results suggest that patchy stomatal closure signaled by the increase in VPD, in transpiration and by circadian rhythms, was the key factor in constraining midday leaf gas exchange of the D. sublamellatus canopy leaves.

Abstract
The oxygen isotope enrichment of bulk leaf water (Delta(b)) was measured in cotton (Gossypium hirsutum) leaves to test the Craig-Gordon and Farquhar-Gan models under different environmental conditions. Delta(b) increased with increasing leaf-to-air vapor pressure difference (VPd) as an overall result of the responses to the ratio of ambient to intercellular vapor pressures (e(a)/e(i)) and to stomatal conductance (g(s)). The oxygen isotope enrichment of lamina water relative to source water (Delta(1)), which increased with increasing VPd, was estimated by mass balance between less enriched water in primary veins and enriched water in the leaf. The Craig-Gordon model overestimated Delta(b) (and Delta(1)), as expected. Such discrepancies increased with increase in transpiration rate (E), supporting the Farquhar-Gan model, which gave reasonable predictions of Delta(b) and Delta(1) with an L of 7.9 mm, much less than the total radial effective length L(r) of 43 mm. The fitted values of L for Delta(1) of individual leaves showed little dependence on VPd and temperature, supporting the assumption that the Farquhar-Gan formulation is relevant and useful in describing leaf water isotopic enrichment.

Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disease. Cortical tubers are one of the standard intracranial hallmarks of TSC, they comprise subependymal hamartomas protruding into the ventricles, cortical and white matter hamartomas, and giant cell tumors. The clinical course of TSC varies from asymptomatic to severe, with epileptic seizures and psychomotor retardation. We discuss here the correlation between clinical manifestation and features on 1H-MR spectroscopy ( 1H-MRS) of the white matter involving cortical tubers in patients with TSC. Statistical analysis of the N-acetylaspartate (NAA), choline (Cho) and myoinositol (mI)/creatinine (Cr) ratios between tubers and normal controls showed decreased NAA/Cr and increased mI/Cr ratios (P<0.05) in tubers, but no significance difference in Cho/Cr. The significance of the clinical appearance is associated with a decreased ratio of NAA/Cr in tubers with TSC. An elevated ratio of mI/Cr in tuber does not parallel the severity of the clinical features of TSC. These findings suggest that 1H-MRS may be useful for the evaluation of the clinical severity and prognostic diagnosis of TSC.

Abstract
Seasonal fluctuations in leaf gas exchange parameters were investigated in three evergreen (Quercus glauca Thunb., Cinnamomum camphora Sieb. and Castanopsis cuspidata Schottky) and one deciduous (Quercus serrata Thunb.) co-occurring, dominant tree species in a temperate broad-leaved forest. Dark respiration rate (Rn), maximum carboxylation rate (Vcmax) and stomatal coefficient (m), the ratio of stomatal conductance to net assimilation rate after adjustment to the vapor pressure deficit and internal carbon dioxide (CO2) concentration, were derived inversely from instantaneous field gas exchange data (one-point method). The normalized values of Rn and Vcmax at the reference temperature of 25 degrees C (Rn25, Vcmax25) and their temperature dependencies (Delta Ha(Rn), Delta Ha(Vcmax)) were analyzed. Parameter Vcmax25 ranged from 24.0-40.3 micromol m(-2) s(-1) and Delta Ha(Vcmax) ranged from 29.1- 67.0 kJ mol(-1). Parameter Rn25 ranged from 0.6-1.4 micromol m(-2) s(-1) and Delta Ha(Rn) ranged from 47.4-95.4 kJ mol(-1). The stomatal coefficient ranged from 7.2-8.2. For the three evergreen trees, a single set of Vcmax25 and Rn25 parameters and temperature dependence curves produced satisfactory estimates of carbon uptake throughout the year, except during the period of simultaneous leaf fall and leaf expansion, which occurs in April and May. In the deciduous oak, declines in Vcmax25 were observed after summer, along with changes in Vcmax25 and Rn25 during the leaf expansion period. In all species, variation in m during periods of leaf expansion and drought should be considered in modeling studies. We conclude that the changes in normalized gas exchange parameters during periods of leaf expansion and drought need to be considered when modeling carbon uptake of evergreen broad-leaved species.

Abstract
Although 2% glutaraldehyde is often the first-line agent for endoscopic disinfection, its adverse reactions are common among staff and it is less effective against certain mycobacteria and spore-bearing bacteria. Chlorine dioxide is a possible alternative and an automated washer-disinfector fitted with this agent is currently available. This study was conducted to evaluate the effectiveness of chlorine dioxide in endoscopic disinfection after upper gastrointestinal examination. In vitro microbicidal properties of chlorine dioxide solutions were examined at high (600 ppm) and low (30 ppm) concentrations against various microbes including Pseudomonas aeruginosa, Helicobacter pylori, Mycobacterium avium-intracellulare and Bacillus subtilis in the presence or absence of bovine serum albumin (BSA). Immediately following endoscopic procedures and after application to the automated reprocessor incorporating chlorine dioxide at 30 ppm for 5 min, endoscopic contamination with infectious agents, blood, H. pylori ureA gene DNA and HCV-RNA was assessed by cultivation, sensitive test tape, polymerase chain reaction (PCR) and reverse transcriptase-PCR analysis, respectively. Chlorine dioxide at 30 ppm has equivalent microbicidal activity against most microbes and faster antimicrobial effects on M. avium-intracellulare and B. subtilis compared with 2% glutaraldehyde, but contamination with BSA affected the microbicidal properties of chlorine dioxide. Endoscopic contamination with microbes, blood and bacterial DNA was eliminated after application of the automated reprocessor/chlorine dioxide system. Thus, chlorine dioxide is a potential alternative to glutaraldehyde. The use of automated reprocessors with compatibility to chlorine dioxide, coupled with thorough pre-cleaning, can offer effective, faster and less problematic endoscopic disinfection.

Abstract
Mitochondrial acetoacetyl-CoA thiolase (T2) deficiency is an inborn error of metabolism affecting isoleucine and ketone bodies in the catabolic process. Mutation analysis and expression analysis of mutant cDNAs have facilitated the division of T2-deficient patients into two groups: those with null mutations in either allele (group 1) and those with mutation(s) retaining some residual T2 activity in at least one of two mutant alleles (group II). Among 5 Japanese T2-deficient patients, GK01 belonged to group I and the other patients (GK19, GK19B, GK30 and GK31) to group II. As we have suggested previously, the severity of ketoacidotic episodes in the group II patients was similar to that in the group I patient. However, the urinary organic acid and blood spot acylcarnitine profiles under stable conditions differed between the two groups. The group I patient had typical profiles for the T2 deficiency. In contrast, in all four patients in group II, tiglylglycine was not or was only faintly detected and the 2-methyl-3-hydroxybutyrate levels were less than the cutoff value. Their tiglylcarnitine levels were within the normal range and 2-methyl-3-hydroxy-, butyrylcarnitine was detected just around the cutoff value in our newborn screening pilot test. Hence, these analyses under stable conditions are not reliable for diagnosing the T2 deficiency in the group II patients. The T2 deficiency (group II) can be misdiagnosed as normal if these analyses are performed under nonepisodic conditions and possibly during the newborn screening for inborn errors of metabolism.

Abstract
A new pharmaceutical aseptic vial filling system has been developed based on isolator technology that is also well suited to use in conventional clean rooms. The results of experiments designed to test the microbiological quality of the environment provided by the new filling system in conjunction with an isolator demonstrate that the isolator enclosed filler can be readily decontaminated and that it can maintain an aseptic environment for at least one month under worse case conditions.

Abstract
Respiratory distress is one of the major complications in young infants with pulmonary atresia, ventricular septal defect and major aortopulmonary collateral arteries (PA-VSD-MAPCA); however, its aetiology remains obscure. We have previously reported an association of bronchomalacia with PA-VSD-MAPCA in patients with a hemizygous deletion of chromosome 22q11.2 (del.22q11). To clarify the clinical relevance of bronchomalacia in patients with PA-VSD-MAPCA and del.22q11, we reviewed the clinical and laboratory records of four patients with PA-VSD-MAPCA who had del.22q11 and bronchomalacia. External bronchial compression by anomalous patterning of the aorta and MAPCA was documented in three of the four patients, using combinatorial examination of angiocardiography, bronchography, fibreoptic bronchoscopy and magnetic resonance imaging. One of the four patients died suddenly of severe respiratory distress at 4 years of age, while the remaining three were inoperable for complete surgical repair. Our study indicates that bronchomalacia as a result of external vascular compression may be an aetiology of early-onset respiratory distress in some patients with PA-VSD-MAPCA and del.22q11, and can significantly affect the clinical outcome.

Abstract
Previously, we showed that incubation of the scallop sarcoplasmic reticulum (SR) with EGTA at above 37 degrees C resulted in the uncoupling of ATP hydrolysis with Ca2+ transport [Nagata et al. (1996) J. Biochem. 119, 1100-1105]. We have extended this study by comparing the kinetic behavior of Ca2+ release and binding to the uncoupled SR with that of intact scallop or rabbit SR. The change in the Ca2+ concentration in the reaction medium, as determined as the absorption of APIII, was followed using a stopped flow system. Intact scallop SR was preincubated with Ca2+ in the presence of a Ca2+ ionophore, A23187, and then ATP was added to initiate the reaction. The Ca2+ level in the medium increased to the maximum level in several seconds, and then slowly decreased to the initial low level. The rising and subsequent slow decay phases could be related to the dissociation and reassociation of Ca2+ with the Ca-ATPase, respectively. When uncoupled scallop SR vesicles were preincubated with CaCl2 in the absence of A23187 and then the reaction was initiated by the addition of ATP, a remarkable amount of Ca2+ was released from the SR vesicles into the cytosolic solution, whereas, with intact scallop or rabbit SR, only a sharp decrease in the Ca2+ level was observed. Based on these findings, we concluded that the heat treatment of scallop SR in EGTA may alter the conformation of the Ca-ATPase, thereby causing Ca2+ to be released from the enzyme, during the catalytic cycle, at the cytoplasmic surface, but not at the lumenal surface of SR vesicles.

Abstract
OBJECTIVE The objective of this study was to examine the effect of dietary diacylglycerol (DAG) on the bioavailability of fat-soluble vitamins in comparison with triacylglycerol (TAG). METHODS We conducted a long-term administration test of DAG and TAG in 27 healthy men aged 27-47 years. After measuring baseline values, subjects were randomized into two groups, one group (n = 15) was given DAG and the other (n = 12) was given TAG. Subjects ingested 20 g of DAG or TAG either in mayonnaise or an emulsion drink of their own choice at meals once a day for 12 weeks. At 4, 8 and 12 weeks, fasting blood samples were drawn and serum levels of vitamin A, E, and D were measured. RESULTS There were no significant changes in vitamin A levels throughout the study period. Compared to the initial values (using a Student's t test for paired values), significant differences of vitamin E and D were seen at some points during the experiment. According to a two-way repeated measures analysis of variance, however, DAG and TAG (lipid) and time had no effect on fat-soluble vitamin levels. CONCLUSIONS Our results indicate that DAG does not affect the absorption of the fat-soluble vitamins in diets.

Abstract
BACKGROUND Early use of inhaled steroids is recommended for bronchial asthma. The side effects are rare, but oral discomfort and candidiasis are clinically important complications. Most previous studies reported that the use of spacer and water gargling was necessary to prevent oral complications. However, in some patients, this may fail to prevent such complications. OBJECTIVE To compare the effects of water gargling with those of amphotericin B, in the prevention of oral complications in asthmatics using inhaled steroids. METHODS Pharyngeal swab samples were obtained aseptically from the posterior pharyngeal wall of 128 asthmatics who have been using inhaled steroids (beclomethasone dipropionate) for more than 1 year. The amount of Candida albicans in cultured swabs was evaluated based on the following criteria: oral symptoms, method of gargling, dose of inhaled steroids, type of spacer and serum cortisol level. RESULTS The number of isolated C. albicans was significantly higher in asthmatics with oral symptoms than in those free of symptoms. It was also significantly higher in patients who gargled with water or 1,000 times dilution than in those who gargled with 100 or 50 times dilutions of amphotericin B. Moreover, it was significantly higher in patients with low levels of serum cortisol than in those with normal serum cortisol. CONCLUSION We demonstrated that at least in a subgroup of asthmatics using steroid inhalers, gargling with water or even weak concentrations of amphotericin B does not prevent colonization of the throat with C. albicans. This group at high risk of developing oral candidiasis should gargle with amphotericin B at concentrations higher than 100 times dilution that can prevent clinically detectable oral candidiasis.

Abstract
We report on fluorescence in situ hybridization (FISH) analysis in 30 mosaic or nonmosaic females diagnosed as having apparently simple terminal X deletions by standard G-banding analysis. FISH studies for DXZ1, the Xp and Xq telomere regions, and the whole X chromosome painting were carried out for the 30 females, indicating rearranged X chromosomes with signal patterns discordant with terminal deletions in 6 cases: one dic(X)(DXZ1++) chromosome, two der(X)(qtel++) chromosomes, one Xq- (qtel+) chromosome, and two der(X)(ptel++) chromosomes. Additional FISH studies were performed for the 6 cases using probes defining 12 loci on the X chromosome, showing large Xp deletion and small Xp duplication in the dic(X)(DXZ1++) chromosome, partial Xp deletions and partial Xq duplications in the two der(X)(qtel++) chromosomes, an interstitial Xq deletion in the Xq- (qtel+) chromosome, and partial Xq deletions and partial Xp duplications in the two der(X)(ptel++) chromosomes. Clinical assessment of the 6 cases revealed tall and normal stature in the two mosaic cases with the der(X)(ptel++) chromosomes that were shown to be associated with SHOX duplication. The results suggest that unusual X chromosome rearrangements are often misinterpreted as simple terminal X deletions, and that FISH analysis is useful for precise structural determination and better genotype-phenotype correlation of the X chromosome aberrations.

Abstract
The autonomic nervous system is affected in a wide variety of neurological disorders. Its dysfunction may play an important role in the clinical course and may result in serious complications, such as cardiac arrest. We report a case of tetanus who presented with severe autonomic nervous system dysfunction which was detected by spectral analysis of heart rate variability monitored over 24 h. This is a semi-quantitative method for evaluation of the status of the autonomic nervous system. In the present case, the analysis revealed profoundly decreased activity of both sympathetic and parasympathetic nervous system modulation of cardiac rhythm. The parasympathetic nervous system activity was more severely impaired than that of the sympathetic nervous system. The relative predominance of the sympathetic nervous system in the present case may have resulted in unopposed sympathetic nervous system hyperactivity manifested in this patient by tachycardia and excessive sweating. We further infer that the documented diminished buffering capacity of the autonomic nervous system may have lead to a sudden cardiac arrest in our case. Thus, spectral analysis of heart rate variability is a non-invasive and sensitive method for evaluating the status of the autonomic nervous system of critically ill patients in the hospital setting.

Abstract
We examined the effect of daily consumption of dietary diacylglycerol (DG) oil on serum lipid concentrations in patients with diabetes whose serum triacylglycerol (TG) levels were persistently increased despite continuous nutritional counseling at the outpatient clinic. Patients (n = 16) were divided into DG and control groups (n = 8 each). DG was incorporated (target dose 10 g/d) by substituting DG oil (80 g DG/100 g oil) for the ordinary TG cooking oil used at home for 12 wk. The control group continued consuming ordinary TG cooking oil. Dietary records indicated that there were no differences between groups in total energy intake or percentage of energy from fat. In the DG group, TG intake decreased from 26.8 +/- 9.3 to 15.7 +/- 8.9 g/d, whereas DG intake increased from 0.3 +/- 0.1 to 10.6 +/- 3.9 g/d. No differences between groups were observed in body weight, total fat intake or total oil consumption throughout the study period. In the DG group, serum TG levels decreased 39.4% from 2.51 +/- 0.75 mmol/L to 1.52 +/- 0.28 mmol/L. Serum glycohemoglobin A(1c) (HbA(1c)) concentration also decreased 9.7%. In contrast, there were no changes in these variables in the control group. Serum total and HDL cholesterol were not affected in either group. These results indicate that DG oil may be useful as an adjunct to the standard diet therapy of fat restriction in the management of diabetics with hypertriglyceridemia.
