Abstract

Carbonaceous chondrites are considered to have originated from C-type asteroids and represent some of the most primitive material in our solar system. Furthermore, since carbonaceous chondrites can contain significant quantities of volatile elements, they may have played a crucial role in supplying volatiles and organic material to Earth and other inner solar system bodies. However, a major challenge of unravelling the volatile composition of chondritic meteorites is distinguishing between which features were inherited from the parent body, and what may be a secondary feature attributable to terrestrial weathering. In December 2020, the Hayabusa2 mission of the Japan Aerospace Exploration Agency (JAXA) successfully returned surface material from the C-type asteroid (162173) Ryugu to Earth. This material has now been classified as closely resembling CI-type chondrites, which are the most chemically pristine meteorites. The analysis of material from the surface of Ryugu therefore provides a unique opportunity to analyse the volatile composition of material that originated from a CI-type asteroid without the complications arising from terrestrial contamination. Given their highly volatile nature, the noble gas and nitrogen inventories of chondrites are highly sensitive to different alteration processes on the asteroid parent body, and to terrestrial contamination. Here, we investigate the nitrogen and noble gas signature of two pelletized grains collected from the first and second touchdown sites (Okazaki et al., 2022a), to provide an insight into the formation and alteration history of Ryugu. The concentration of trapped noble gas in the Ryugu samples is greater than the average composition of previously measured CI chondrites and are primarily derived from phase Q, although a significant contribution of presolar nanodiamond Xe-HL is noted. The large noble gas concentrations coupled with a significant contribution of presolar nanodiamonds suggests that the Ryugu samples may represent some of the most primitive unprocessed material from the early solar system. In contrast to the noble gases, the abundance of nitrogen and δ15N composition of the two Ryugu pellets are lower than the average CI chondrite value. We attribute the lower nitrogen abundances and δ15N measured in this study to the preferential loss of a 15N-rich phase from our samples during aqueous alteration on the parent planetesimal. The analyses of other grains returned from Ryugu have shown large variations in nitrogen concentrations and δ15N indicating that alteration fluids heterogeneously interacted with material now present on the surface of Ryugu. Finally, the ratio of trapped noble gases to nitrogen is higher than CI chondrites, and is closer to refractory phase Q and nanodiamonds. This indicates that Ryugu experienced aqueous alteration that led to the significant and variable loss of nitrogen, likely from soluble organic matter, without modification of the noble gas budget, which is primarily hosted in insoluble organic matter and presolar diamonds and is therefore more resistant to aqueous alteration., Geochimica et Cosmochimica Acta, 345, ISSN:0016-7037, ISSN:1872-9533

Abstract

The development of reduced models provide efficient methods that can be used to perform short term experimental data analysis or narrow down the parametric range of more sophisticated numerical approaches. Reduced models are derived by simplifying the physics description with the goal of retaining only the essential ingredients required to reproduce the phenomena under study. This is the role of the gyro-fluid code FAR3d, dedicated to analyze the linear and nonlinear stability of Alfvén Eigenmodes (AE), Energetic Particle Modes (EPM) and magnetic-hydrodynamic modes as pressure gradient driven mode (PGDM) and current driven modes (CDM) in nuclear fusion devices. Such analysis is valuable for improving the plasma heating efficiency and confinement; this can enhance the overall device performance. The present review is dedicated to a description of the most important contributions of the FAR3d code in the field of energetic particles (EP) and AE/EPM stability. FAR3d is used to model and characterize the AE/EPM activity measured in fusion devices as LHD, JET, DIII-D, EAST, TJ-II and Heliotron J. In addition, the computational efficiency of FAR3d facilitates performing massive parametric studies leading to the identification of optimization trends with respect to the AE/EPM stability. This can aid in identifying operational regimes where AE/EPM activity is avoided or minimized. This technique is applied to the analysis of optimized configurations with respect to the thermal plasma parameters, magnetic field configuration, external actuators and the effect of multiple EP populations. In addition, the AE/EPM saturation phase is analyzed, taking into account both steady-state phases and bursting activity observed in LHD and DIII-D devices. The nonlinear calculations provide: the induced EP transport, the generation of zonal structures as well as the energy transfer towards the thermal plasma and between different toroidal/helical families. Finally, FAR3d is used to forecast the AE/EPM stability in operational scenarios of future devices as ITER, CFETR, JT60SA and CFQS as well as possible approaches to optimization with respect to variations in the most important plasma parameters.

Abstract

Introduction: Many reports show that denture adhesives improve the retention and stability of dentures. However, few randomized controlled trials have examined the effects of denture adhesives. Objective: This 10-center randomized controlled trial with parallel groups involving 200 edentulous patients wearing complete dentures aimed to evaluate the effects of short-term use of cream and powder denture adhesives. Methods: Patients were allocated into 2 cream- and powder-type adhesive groups and 1 control group. Intervention groups were treated with the 2 adhesives (1 each), and the control group received saline solution. Adhesive or control was applied to the denture-mucosal surface for 4 d, and data at baseline and after day 4 of intervention (i.e., 8 meals) were obtained. Patient satisfaction was evaluated with a 100-mm visual analog scale. Oral health–related quality of life was measured with the Japanese version of the Oral Health Impact Profile for Edentulous Patients. Perceived chewing ability was evaluated by a questionnaire regarding ease of chewing and swallowing food. Between-group comparisons were performed with Kruskal-Wallis tests with the Mann-Whitney U test adjusted by Bonferroni correction. Within-group comparisons of pre- and postintervention measurements were performed with the Wilcoxon signed-rank test. Intention-to-treat analysis was also performed. Results: Between-group comparisons showed no significant differences for general satisfaction or Oral Health Impact Profile for Edentulous Patients. However, significant differences in satisfaction with various denture functions with cream- and powder-type adhesives were seen in pre- and postintervention comparisons ( P < 0.05). Significant differences were also observed for perceived chewing ability of hard foods ( P < 0.05). Conclusion: These results suggest that although denture adhesives do not invariably improve denture function, they do affect subjective evaluations and possibly chewing of hard foods. Therefore, the effects of denture adhesive use are insufficient to resolve any fundamental dissatisfaction with dentures ( ClinicalTrials.gov NCT01712802 ). Knowledge Transfer Statement: The results of this study suggest that denture adhesives should be applied under certain conditions; however, an appropriate diagnosis is important before application. These practice-based data provide information to establish evidence-based guidelines for applying denture adhesives.

Abstract

Introduction Genitourinary syndrome of menopause (GSM) is a symptom complex that occurs secondary to vulvovaginal atrophy. It is generally accepted that GSM is more prevalent in postmenopausal women, and that it can affect their quality of life (QOL). However, there is little data regarding GSM in Japan. Objective The aim of this survey was (i) to determine the prevalence of vulvovaginal symptoms of GSM among Japanese peri- and post-menopausal women and (ii) to examine whether sexual activity affected the prevalence of GSM. Methods We conducted an online survey of 4,134 Japanese women aged 40 – 79 years in the general population. In this primary study, we focused on vulvovaginal symptoms of GSM. GSM was defined as a condition characterized by presenting at least one vaginal symptom such as vulva dryness, vulva hurting, dryness during sexual activity, and dyspareunia using the vulvovaginal symptoms questionnaire. The correlations between age, sexual activity, and GSM were analyzed. Results The prevalence of GSM was 11.6%. The respondents who reported GSM were more likely to be younger. The most common symptom was vulva dryness (6.0%). Only 22.0% of respondents were currently sexually active. Sexual activity was significantly correlated with GSM (P Conclusions The vulvovaginal symptoms of GSM were not found with high frequency in Japanese peri- and post-menopausal women. This primary study was conducted in limited areas of GSM. We are planning to analyze the features of GSM including urinary symptoms and QOL more comprehensively with our whole database.

Abstract

This paper describes the numerical study for the development of a double scroll(DS) turbine stage combined with a variable geometry system (VGS). Our conventional VGS turbine stage is composed of a mono-scroll housing, variable nozzles and a turbine wheel. A potential to improve engine performance by applying a DS with VGS turbine stage (DS-VGS) was shown by the study. In addition, a DS-VGS has some advantage in the layout for V type engine. Therefore, this study has focused on clarifying the characteristics of aerodynamic performance of a DS-VGS, since the understanding of these fundamental characteristics is important for product development. The differences of performance between a mono-scroll with VGS and a DS with VGS were evaluated as the starting point. In the development for a vaneless DS turbine so far, it has been clarified that the distance from tongue to turbine wheel is one of the important parameters for performance. Therefore, numerical simulations were performed with different tongue-to-nozzle distances. Further, from reliability point of view, the influences of a DS on nozzle moments and aerodynamic forces on nozzle have been examined. The interesting characteristics of a DS-VGS compared to a mono-scroll with VGS are shown.

Abstract

Aim To evaluate the effects of early (≤6 months after starting any medical treatment [baseline] for benign prostatic hyperplasia [BPH]), intermediate (between >6 months and 2 years from baseline) and late (2 years after baseline) initiation of add-on dutasteride therapy on the incidence of acute urinary retention (AUR) and BPH-related surgery in Japanese patients with moderate-to-severe BPH. Methods This multicentre, observational, retrospective chart review study used anonymised data from Japanese medical records. Eligible patients (≥50 years) were followed from baseline until first AUR, BPH-related surgery or Year 4. Results Overall, 1206 patients were included (early initiation: n = 793; intermediate: n = 233; late: n = 180). Early dutasteride initiation was not superior to late initiation in reducing the risk of first AUR or BPH-related surgery from baseline (hazard ratio [HR] 0.733; 95% confidence interval [CI] 0.468-1.150) but was superior in reducing the risk of first AUR alone (HR 3.449; 95% CI 1.796-6.623). One year after initiation, the cumulative incidence of first AUR rose rapidly in the late vs early and intermediate initiation groups. Incidences of all parameters (first AUR/BPH-related surgery, first AUR alone and BPH-related surgery alone) in patients undergoing BPH-related surgery in low incidence sites (ie clinical sites with ≤ 16% incidence of first AUR or BPH-related surgery) were significantly lower in the early vs late initiation groups. Conclusion Early dutasteride initiation reduced the risk of AUR in a Japanese real-world setting. A randomised controlled trial is warranted to evaluate the benefit of early initiation in preventing BPH-related surgery in Japanese patients.

Abstract

BackgroundImmune response indicators in the early phase of COVID-19, including interferon and neutralizing responses against SARS-CoV-2, which predict hypoxemia remains unclear.MethodsThis prospective observational study recruited patients hospitalized with COVID-19 (before emergence of omicron variant). As the immune indicators, we assessed the serum levels of IFN-I/III, IL-6, CXCL10 and VEGF, using an ELISA at within 5 days after the onset of symptoms, and serum neutralizing responses using a pseudovirus assay. We also assessed SARS-CoV-2 viral load by qPCR using nasal-swab specimens and serum, to assess the association of indicators and viral distribution.ResultsThe study enrolled 117 patients with COVID-19, of which 28 patients developed hypoxemia. None received vaccine before admission. Serum IFN-I levels (IFN-α and IFN-β), IL-6, CXCL10, LDH and CRP were significantly higher in patients who developed hypoxemia. A significant association with nasopharyngeal viral load was observed only for IFN-I. The serum levels of IFN-α, IL-6, CXCL10 were significantly associated with the presence of RNAemia. Multivariable analysis showed higher odds ratio of IFN-α, with cut-off value of 107 pg/ml, in regard to hypoxemia (Odds ratio [OR]=17.5; 95% confidence interval [CI], 4.7-85; p17.9 pg/ml (OR=10.5; 95% CI, 2.9-46; p

Abstract

Recently, experiments on basic plasma physics issues for solving future problems in fusion energy have been performed on a Large Helical Device. There are several problems to be solved in future devices for fusion energy. Emerging issues in burning plasma are: alpha-channeling (ion heating by alpha particles), turbulence and transport in electron dominant heating helium ash exhaust, reduction of the divertor heat load. To solve these problems, understanding the basic plasma physics of (1) wave–particle interaction through (inverse) Landau damping, (2) characteristics of electron-scale (high- k ) turbulence, (3) ion mixing and the isotope effect, and (4) turbulence spreading and detachment, is necessary. This overview discusses the experimental studies on these issues and turbulent transport in multi-ion plasma and other issues in the appendix.

Abstract

Dense film electrodes of La 0.6 Sr 0.4 CoO 3 were formed on ceria based solid electrolytes by pulsed laser deposition. The oxygen exchange reaction rate on the surface was evaluated by impedance spectroscopy, and the effect of coexistence of LaSrCoO 4 phase on the surface was investigated. The tendency of Sr segregation on the surface of La 0.6 Sr 0.4 CoO 3 was mitigated by addition of porous LaSrCoO 4 layer, which reduced the activation energy of oxygen exchange reaction and enhanced the reaction rate.

Abstract

It is well known that in protein-starved chickens, small amounts of amino acid supplement, especially methionine, reduces nitrogen excretion and thereby improves nitrogen balance. On the other hand, excess intake of methionine causes growth depression and the growth-depressive effect of excess methionine can be alleviated by consumption of dietary glycine. Insulin-like growth factor-I (IGF-I) is one of various growth-promoting factors relating to the efficiency of animal production and is known to be very sensitive to changes in nutritional status. In the present study, the interactive effect of glycine on nitrogen sparing effect of methionine in protein-starved chickens was examined. In addition, the relation of IGF-I and its specific binding protein to the nitrogen sparing effect of supplemented methionine was also investigated. Two-days refeeding of methionine supplemented to protein-free diet could promptly alleviate body weight loss in protein-starved chickens, and the alleviation of body weight loss by methionine was not improved by glycine supplements. Moreover, such acute alleviation of body weight loss by dietary methionine was independent of the change in plasma IGF-I concentration.

Abstract

It has been found that female progeny with the early feathering (EF) phenotype rarely emerge in late feathering (LF) strains of chickens. However, few detailed studies on the incidence of reversion have been reported. The present study was conducted to examine the incidence of reversion across three generations (G7-G9) in an LF line of the Nagoya breed and to investigate the characteristics of DNA structures of the revertant EF females. A total of five EF revertant females were observed (G7: 3 out of 376, G8: 1 out of 383, G9: 1 out of 411), and the incidences observed in G7, G8, and G9 were 0.80, 0.26, and 0.24%, respectively. Results of two PCR and one RFLP-PCR analyses indicated that there were two types of EF revertants in the Nagoya breed (3 birds were Type I and 2 birds were Type II), and that the reversion to the EF phenotype might be accompanied by the loss of either an OR (occupied repeat) or a UR-K region (unoccupied repeat on the K locus), which were homologous DNA regions produced by insertion of an avian endogenous virus gene (ev21) and duplication. Moreover, phenotypes of full-sib and half-sib sisters of the EF revertants confirmed that the sires of the EF revertants have never harbored excision of either OR or UR-K at the ev21-K complex locus on one of two Z chromosomes, suggesting that the reversion event occurred in spermatogenesis.

Abstract

The HEK 293 cell line (293 cells) was derived from human embryonic kidney (HEK) cells grown in tissue culture. 293 cells are very easy to grow and transfect and have been widely used in cell biological research for many years. 293 cells have many of the properties of immature neurons, suggesting that they represent a transformed neuronal cell present in the original kidney culture, and they are not useful as an in vitro model for kidney cell function. The 293T cell line contains the SV(4)0 large T-antigen, which allows the episomal replication of transfected plasmids containing the SV40 origin of replication, and 293FT cells are a fast-growing variant. A recent report showed that introducing a set of transcription factors associated with pluripotency into human somatic cells can directly reprogr am them to produce induced pluripotent stem (iPS) cells. To date, however, iPS cells have not been generated from immortalized cells. We examined whether iPS cells could be generated from 293 FT cells transfected with four transcription factors (OCT4, SOX2, NANOG, and LIN28). The obtained cells morphologically resembled human ES cells, and showed a similar marker gene expression pattern. These cells had an impaired ability to differentiate, and formed immature ectodermal tumors after they were transplanted into nude mice. Thus, we could not derive fully reprogrammed iPS cells from 293FT cells. We conclude that the 293FT cells transduced with OCT4, SOX2, NANOG, and LIN28 produced aberrant ES-like cells.

Abstract

RS-127445 is a selective, high affinity 5-HT(2B)receptor antagonist. We investigated whether 5-HT(2B)receptor antagonists can reduce colonic visceral hypersensitivity caused by restraint stress or by proximal colonic inflammation.Visceral hypersensitivity was induced in rats by either restraint stress or injection of 2, 4, 6-trinitrobenzene sulfonic acid (TNBS) into the proximal colon. Restraint stress produced a significant increase in numbers of abdominal contractions evoked by colorectal distension (CRD), measured as a quantitative index of visceral nociception in rats. Seven days after TNBS injection, the pain threshold to CRD at the non-inflamed distal colon, that was determined as the minimum pressure required to evoke abdominal cramp, was significantly decreased. The effect of RS-127445 on visceral hypersensitivity was assessed in either naïve or TNBS-treated rats.Oral administration of a selective, high affinity 5-HT(2B)receptor antagonist, RS-127445, significantly inhibited visceral hypersensitivity provoked by restraint stress (35 to 74% inhibition at 1 to 10 mg kg(-1)). Oral RS-127445 produced a significant suppression of TNBS-induced visceral hypersensitivity (15 to 62% inhibition at 3 to 30 mg kg(-1)), although it was without significant effect on the visceral nociceptive threshold of naïve rats. RS-127445 (1 to 30 mg kg(-1), p.o.) also dose-dependently reduced the restraint stress-induced defecation in naïve and TNBS-treated rats.These results suggest that 5-HT(2B)receptors are involved in signaling from the colon in rats in which there is visceral hypersensitivity and that a selective 5-HT(2B)receptor antagonist could have therapeutic potential for the treatment of gut disorders characterized by visceral hypersensitivity.

Abstract

The influence of varying dietary proteins levels from 0% to 18%, which is the level of dietary protein requirement, on plasma IGF-I concentration and tissue IGFBP-2 and -4 gene expression was examined. Body weight gain was gradually lowered by decreasing dietary protein levels from 18% to 4.5%, and body weight was lost when chickens fed a protein-free diet. Plasma IGF-I concentration of chickens fed the 18% crude protein diet was the highest of all, and it was gradually decreased by reducing dietary protein concentrations. Gene expression of IGFBP-2 in the gizzard was elevated by decreasing dietary protein levels from 18% to 9%, and the further reduction in dietary protein content lowered gizzard IGFBP-2 gene expression. No significant change in hepatic IGFBP-4 gene expression was observed in chickens fed experimental diets with varying dietary protein levels. Multiple linear regression analysis revealed that the influence of the change in plasma IGF-I concentration and gizzard IGFBP-2 gene expression on body weight change of chickens fed varying amounts of dietary protein seemed to be independent because the interactive effect of both factors on body weight change was not significant.

Abstract

Objectives - Collagen abnormalities of skin have been reported in patients with amyotrophic lateral sclerosis (ALS). However, little is known concerning the aminoterminal propeptide of type III procollagen (PIIIP) and type III collagen in ALS. The aim of this study is to measure PIIIP, a precursor form of type III collagen, in skin and serum of ALS. Material and methods - We studied PIIIP immunoreactivity of skin and measured serum levels of PIIIP in ALS patients, and the results were compared with those of control subjects. Results - Collagen bundles in the dermis of ALS were immunohistochemically strongly positive for PIIIP as compared with those of controls. The optical density of PIIIP immunostaining reactivity in ALS patients was significantly higher than in controls, and was significantly increased with duration of illness. Serum PIIIP levels in patients with ALS were significantly increased as compared with those in diseased control subjects and those in healthy control ones, and were positively and significantly associated with duration of illness. There was an appreciable positive correlation between concentrations of serum PIIIP and the density of PIIIP immunoreactivity of skin in ALS patients. Conclusion - These data suggest that a metabolic alteration of PIIIP may take place in the skin of ALS and the increased levels of serum PIIIP may reflect the increased PIIIP immunoreactivity of skin in ALS.

Abstract

The Los Angeles classification system is the most widely employed criteria associated with the greatest interobserver agreement among endoscopists. In Japan, the Los Angeles classification system has been modified (modified LA system) to include minimal changes as a distinct grade of reflux esophagitis, rather than as auxiliary findings. This adds a further grading M defined as minimal changes to the mucosa, such as erythema and/or whitish turbidity. The modified LA system has come to be used widely in Japan. However, there have been few reports to date that have evaluated the interobserver agreement in diagnosis when using the modified LA classification system incorporating these minimal changes as an additional grade. A total of 100 endoscopists from university hospitals and community hospitals, as well as private practices in the Osaka-Kobe area participated in the study. A total of 30 video clips of 30-40 seconds duration, mostly showing the esophagocardiac junction, were created and shown to 100 endoscopists using a video projector. The participating endoscopists completed a questionnaire regarding their clinical experience and rated the reflux esophagitis as shown in the video clips using the modified LA classification system. Agreement was assessed employing kappa (kappa) statistics for multiple raters. The kappa-value for all 91 endoscopists was 0.094, with a standard error of 0.002, indicating poor interobserver agreement. The endoscopists showed the best agreement on diagnosing grade A esophagitis (0.167), and the poorest agreement when diagnosing grade M esophagitis (0.033). The kappa-values for the diagnoses of grades N, M, and A esophagitis on identical video pairs were 0.275-0.315, with a standard error of 0.083-0.091, indicating fair intraobserver reproducibility among the endoscopists. The study results consistently indicate poor agreement regarding diagnoses as well as fair reproducibility of these diagnoses by endoscopists using the modified LA classification system, regardless of age, type of practice, past endoscopic experience, or current workload. However, grade M reflux esophagitis may not necessarily be irrelevant, as it may suggest an early form of reflux disease or an entirely new form of reflux esophagitis. Further research is required to elucidate the pathophysiological basis of minimal change esophagitis.

Abstract

This paper describes the rotating characteristics of a high-Tc superconducting induction/synchronous motor, which possesses both asynchronous and synchronous torques even though its structure is exactly the same as the squirrel-cage-type induction motor. Two kinds of Bi-2223/Ag multifilamentary tapes were utilized for the secondary windings. A commercialized motor (1.5 kW) was subjected to this study. A conventional (normal conducting) stator (three-phase, four-pole) was directly utilized, and only the squirrel-cage windings were replaced with the superconducting tapes. The tests were performed after the fabricated motor was immersed in liquid nitrogen. The operating temperature was also varied by pumping out the liquid nitrogen. It is shown that the motor is successfully synchronized for the temperature range from 65 to 77 K. Detailed discussions for such novel rotating characteristics are reported based on the electrical equivalent circuit.

Abstract

The phosphor material, tris(2-phenylpyridine)iridium (Ir(ppy)3), has attracted much attention as an emitter of highly efficient electro-phosphorescent devices. In the present work, decay dynamics of photo-luminescence and its temperature dependence have been investigated in the Ir(ppy)3 emitting center. From the analyses of luminescent decay profiles and time-resolved luminescent spectra, thermally activated population transfer from every triplet sub-level to a singlet state is suggested.

Abstract

We have investigated the influence of tantalum (Ta) bottom electrodes on the crystallinity and crystal orientation of aluminum nitride (AlN) thin films. AlN thin films and Ta electrodes were prepared by using rf magnetron sputtering method. The crystal structure of the Ta electrodes was tetragonal (β-Ta, a metastable phase) at room temperature. The crystallinity and orientation of the AlN thin films and Ta electrodes strongly depended on sputtering conditions. Especially, the crystallinity and crystal orientation of the Ta electrodes were influenced by their film thickness and the substrate temperature. When the thickness of the Ta bottom electrodes was 200 nm and the substrate temperature was 100 °C, the AlN thin films indicated high c-axis orientation (the full width at half maximum of rocking curve of 3.9°). The crystal orientation of the AlN film was comparable to that of AlN thin films deposited on face centered cubic (fcc) lattice structure metal, such as Au, Pt and Al, bottom electrodes.

Abstract

Abstract Self-organized structure formation in magnetically confined plasmas is one of the most attractive subjects in modern experimental physics. Nonequilibrium media are known to often exhibit phenomena that cannot be predicted by superposition of linear theories. One representative example of such phenomena is the hydrogen isotope effect in fusion plasmas, where the larger the mass of the hydrogen isotope fuel is the better the plasma confinement becomes, contrary to what simple scaling models anticipate. In this article, threshold condition of a plasma structure formation is shown to have a strong hydrogen isotope effect. To investigate the underlying mechanism of this isotope effect, the electrostatic potential is directly measured by a heavy ion beam probe. It is elucidated that the core electrostatic potential transition occurs with less input power normalized by plasma density in plasmas with larger isotope mass across the structure formation. This observation is suggestive of the isotope effect in the radial electric field structure formation.

Abstract

Ghrelin is a novel growth-hormone-releasing acylated peptide, which has been purified and identified in rat stomach. In the present study, the full-length sequence of bovine ghrelin cDNA was cloned by RT-PCR. The bovine ghrelin cDNA sequence derived in the present study included a 348 bp open reading frame and a 137 bp 3'UTR. The putative amino acid sequence of bovine prepro-ghrelin consisted of 116 amino acids, which contained the 27-amino acid ghrelin. The sequence analysis of the bovine ghrelin gene revealed that an intron existed between Gln 13 and Arg 14 of ghrelin. This exon-intron boundary matched the GT-AG rule of the splicing mechanism. Compared with rats, which have two tandem CAG sequences in the 3'-end of intron, bovine ghrelin genome has only one CAG sequence. Therefore, although rats can produce 28 amino acid-ghrelin and 27 amino acid-des-Gln 14 -ghrelin by alternative splicing, ruminant species, including bovines, might be able to produce only one type of ghrelin peptide, des-Gln 14 -ghrelin. The influence of aging on plasma ghrelin concentration was also examined. Plasma ghrelin concentration increased after birth to approximately 600 days of age, and then remained constant. (Asian-Aust.

Abstract

Nutritional regulation of gene expression associated with growth and feeding behavior in avian species can become an important technique to improve poultry production according to the supply of nutrients in the diet. Insulin-like growth factor-I (IGF-I) found in chickens has been characterized to be a 70 amino acid polypeptide and plays an important role in growth and metabolism. Although it is been well known that IGF-I is highly associated with embryonic development and post-hatching growth, changes in the distribution of IGF-I gene expression throughout early- to late-embryogenesis have not been studied so far. We revealed that the developmental pattern of IGF-I gene expression during embryogenesis differed among various tissues. No bands of IGF-I mRNA were detected in embryonic liver at 7 days of incubation, and thereafter the amount of hepatic IGF-I mRNA was increased from 14 to 20 days of incubation. In eyes, a peak in IGF-I mRNA levels occurred at mid-embryogenesis, but by contrast, IGF-I mRNA was barely detectable in the heart throughout all incubation periods. In the muscle, no significant difference in IGF-I gene expression was observed during different stages of embryogenesis. After hatching, hepatic IGF-I gene expression as well as plasma IGF-I concentration increases rapidly with age, reaches a peak before sexual maturity, and then declines. The IGF-I gene expression is very sensitive to changes in nutritional conditions. Food-restriction and fasting decreased hepatic IGF-I gene expression and refeeding restored IGF-I gene expression to the level of fed chickens. Dietary protein is also a very strong factor in changing hepatic IGF-I gene expression. Refeeding with dietary protein alone successfully restored hepatic IGF-I gene expression of fasted chickens to the level of fed controls. In most circumstances, IGF-I makes a complex with specific high-affinity IGF-binding proteins (IGFBPs). So far, four different IGFBPs have been identified in avian species and the major IGFBP in chicken plasma has been reported to be IGFBP-2. We studied the relationship between nutritional status and IGFBP-2 gene expression in various tissues of young chickens. In the liver of fed chickens, almost no IGFBP-2 mRNA was detected. However, fasting markedly increased hepatic IGFBP-2 gene expression, and the level was reduced after refeeding. In the gizzard of well-fed young chickens, IGFBP-2 gene expression was detected and fasting significantly elevated gizzard IGFBP-2 mRNA levels to about double that of fed controls. After refeeding, gizzard IGFBP-2 gene expression decreased similar to hepatic IGFBP-2 gene expression. In the brain, IGFBP-2 mRNA was observed in fed chickens and had significantly decreased by fasting. In the kidney, IGFBP-2 gene expression was observed but not influenced by fasting and refeeding. Recently, we have demonstrated in vivo that gizzard and hepatic IGFBP-2 gene expression in fasted chickens was rapidly reduced by intravenous administration of insulin, as indicated that in young chickens the reduction in gizzard and hepatic IGFBP-2 gene expression in vivo stimulated by malnutrition may be, in part, regulated by means of the increase in plasma insulin concentration via an insulin-response element. The influence of dietary protein source (isolated soybean protein vs. casein) and the supplementation of essential amino acids on gizzard IGFBP-2 gene expression was examined. In both soybean protein and casein diet groups, the deficiency of essential amino acids stimulated chickens to increase gizzard IGFBP-2 gene expression. Although amino acid supplementation of a soybean protein diet significantly decreased gizzard IGFBP-2 mRNA levels, a similar reduction was not observed in chickens fed a casein diet supplemented with amino acids. This overview of nutritional regulation of IGF-I and IGFBP-2 gene expression in young chickens would serve for the establishment of the supply of nutrients to diets to improve poultry production.

Abstract

Functionally active telomerase is affected at various steps including transcriptional and post-transcriptional levels of major telomerase components (hTR and human telomerase reverse transcriptase (hTERT)). We therefore developed a rapid and sensitive method to quantify hTERT and its splicing variants as well as the hTR by a Taqman real-time reverse transcriptase-polymerase chain reaction to determine whether their altered expression may contribute to telomere attrition in vivo or not. Fresh leukaemia cells obtained from 38 consecutive patients were used in this study. The enzymatic level of telomerase activity measured by TRAP assay was generally associated with the copy numbers of full-length hTERT+alpha+beta mRNA (P=0.0024), but did not correlate with hTR expression (P=0.6753). In spite of high copy numbers of full-length hTERT mRNA, telomerase activity was low in some cases correlating with low copy numbers of hTR, raising the possibility that alteration of the hTR : hTERT ratio may affect functionally active telomerase activity in vivo. The spliced nonactive hTERT mRNA tends to be lower in patients with high telomerase activity, suggesting that this epiphenomenon may play some role in telomerase regulation. An understanding of the complexities of telomerase gene regulation in biologically heterogeneous leukaemia cells may offer new therapeutic approaches to the treatment of acute leukaemia.

Abstract

Background and aims: Serum antibodies to carbonic anhydrase (CA) II have been reported in patients with autoimmune pancreatitis (AIP) and Sjogren’s syndrome (SjS). However, their significance in the pathogenesis of these diseases is controversial. The aim of this study was to identify serum antibodies to CA isozymes, which are expressed in ductal cells of the pancreas. Methods: Recombinant proteins of human CAs IV, IX, and XII were obtained using a bacterial expression system, and five CA IV peptides with theoretically high antigenicity were synthesised. Western blotting and enzyme linked immunosorbent assay (ELISA) were used to detect serum antibodies to the CA isozymes. Results: The first screening analysis by western blot showed serum antibodies to CA IV among three CA isozymes in patients with idiopathic chronic pancreatitis, including AIP patients. Further analysis by ELISA showed a significantly increased prevalence of serum antibodies to the truncated CA IV protein and the CA IV synthetic peptide (LGS LTT PTC DEK VVW TVF REP I) in patients with definite AIP (4/15 and 6/20, respectively; p Conclusions: These findings suggest that CA IV may be a target antigen that is commonly expressed in epithelial cells of specific tissues involved in AIP and its related diseases.

Abstract

In order to investigate the self-absorption of the β-rays from 14C in a gel-suspension sample, the Monte Carlo code, simulating the sequence of stages occurring in the sample, has been developed. The trajectory of the electron was calculated by the continuous slowing down approximation and the multiple Coulomb scattering theory. The effects of the self-absorption, strong quenching and particle size distribution of calcium carbonate on the output counting efficiency and the shape of the energy spectrum were evaluated.

Abstract

Kita, K., Kitayama, Y., Nagao, K., Hwangbo, J., Furuse, M. and Okumura, J. 2002. Dietary sorbose ameliorates obesity and hyperglycemia in gold thioglucose-injected obese mice. J. Appl. Anim. Res., 21: 25–32. The influence of dietary sorbose on hyperphagia, hyperglycemia and hyperinsulinemia in gold thioglucose (GTG)–injected obese mice was examined. Body weight of GTG–injected obese mice was decreased by feeding a sorbose diet. When GTG–injected obese mice were given the diet containing sorbose, food intake was significantly lower than that of intact normal mice given a sucrose diet. The reduction in body weight of GTG–injected obese mice given dietary sorbose may be due to the decrease in food intake. Blood glucose concentration in GTG–injected obese mice was decreased by feeding the sorbose diet to the level of intact normal mice given sucrose. Feeding the sorbose diet lowered plasma insulin concentration compared to the sucrose group. It is concluded that feeding sorbose ameliorates hyperphagi...

Abstract

The relationship between nutritional status and insulin-like growth factor binding protein-2 (IGFBP-2) gene expression in chickens was studied. Chickens (6 wk old) were food deprived for 2 d and then refed. IGFBP-2 mRNA in the brain was significantly decreased by food deprivation and levels did not increase when birds were refed for 24 h. Gizzard and hepatic IGFBP-2 mRNA levels were significantly increased by food deprivation and decreased by refeeding. Any nutrients tested decreased hepatic IGFBP-2 gene expression. In kidney, IGFBP-2 mRNA was detected but not influenced by food deprivation and refeeding. In another study, the influence of dietary protein source [isolated soybean protein vs. casein; crude protein (CP) 20%] and the supplementation of essential amino acids on IGFBP-2 gene expression of young chickens (5 wk old) was examined. The influence of feeding a low soybean protein diet (CP 5%) on tissue IGFBP-2 gene expression was also investigated. Hepatic IGFBP-2 mRNA was not detected in any group. Feeding the low protein diet for 7 d decreased brain IGFBP-2 mRNA level and increased gizzard IGFBP-2 level compared with chickens fed 20% protein diets. A significant interaction between protein source and amino acid supplementation was observed in gizzard IGFBP-2 mRNA level. In both casein-fed groups and in chickens fed 20% soybean protein diet without supplemental amino acids, the levels did not differ from one another or from the low protein diet-fed birds. The level was lower in chickens fed the amino acid-supplemented, 20% soybean protein diet. In conclusion, the response of IGFBP-2 gene expression to variations in nutritional status was rapid and different in several tissues of young chickens, which would help modulate the growth-promoting effect of circulating IGF-I by making the IGF-IGFBP complex.

Abstract

In order to elucidate the physiological function of circulating IGF-I on muscle protein synthesis in the chicken under malnutritional conditions, we administrated recombinant chicken IGF-I using a osmotic mini pump to fasted young chickens and measured the rate of muscle protein synthesis and plasma metabolite. The pumps delivered IGF-I at the rate of 22 µg/d {300 µg⋅(kg body weight⋅d) -1 }. Fractional rate of protein synthesis in the muscle was measured using a large dose injection of L-(2,6- 3 H)phenylalanine. Constant infusion of chicken IGF-I did not affect plasma glucose level. Significant interaction between dietary treatment and IGF-I infusion was observed in plasma NEFA and total cholesterol concentrations. When chicks were fasted, IGF-I infusion decreased plasma NEFA and total cholesterol concentrations. On the other hand, IGF-I administration did not affect plasma levels of both metabolites. Fasting reduced plasma triglyceride concentration significantly. IGF-I infusion also decreased the level of plasma triglyceride. Plasma IGF-I concentration of young chickens was halved by fasting for 1 d. IGF-I infusion using an osmotic minipump for 1 d increased plasma IGF-I concentration in fasted chicks to the level of fed chicks. Fasting decreased body weight and the loss of body weight was significantly ameliorated by IGF-I infusion. There was a significant interaction between dietary treatment and IGF-I infusion in the fractional rate of breast muscle protein synthesis. There was no effect of IGF-I infusion on muscle protein synthesis in fed chicks. Muscle protein synthesis reduced by fasting was ameliorated by IGF-I infusion, but did not reach to the level of fed control. Muscle weight of fasted chicks infused with IGF-I was similar to fasted birds without IGF-I infusion, which suggests that muscle protein degradation would be increased by IGF-I infusion as well as protein synthesis in fasted chicks.
