Therapeutic target for nephrotic syndrome: Identification of novel slit diaphragm associated molecules

引用

World Journal of Nephrology 2014年第3期3卷 77-84页

作者： Yoshiyasu Fukusumi Naoko Miyauchi Taeko Hashimoto akira saito Hiroshi Kawachi Department of Cell Biology Institute of Nephrology Niigata University Graduate School of Medical and Dental Sciences Niigata 951-8510 Japan

The slit diaphragm bridging the neighboring foot processes functions as a final barrier of glomerular capillary wall for preventing the leak of plasma proteins into primary urine.It is now accepted that the dysfunction of the sit diaphragm contributes to the development of proteinuria in several glomerular diseases.Nephrin,a gene product of NPHS1,a gene for a congenital nephrotic syndrome of Finnish type,constitutes an extracellular domain of the slit diaphragm.Podocin was identified as a gene product of NPHS2,a gene for a familial steroid-resistant nephrotic syndrome of French.Podocin binds the cytoplasmic domain of nephrin.After then,CD2 associated protein,NEPH1 and transient receptor potential-6 were also found as crucial molecules of the slit diaphragm.In order to explore other novel molecules contributing to the development of proteinuria,we performed a subtraction hybridization assay with a normal rat glomerular RNA and a glomerular RNA of rats with a puromycin aminonucleoside nephropathy,a mimic of a human minimal change type nephrotic syndrome.Then we have found that synaptic vesicle protein 2B,ephrin-B1 and neurexin were already downregulated at the early stage of puromycin amino-nucleoside nephropathy,and that these molecules were localized close to nephrin.It is conceivable that these molecules are the slit diaphragm associated molecules,which participate in the regulation of the barrier function.These molecules could be targets to establish a novel therapy for nephrotic syndrome.

Modern Plastic Surgery 2012年第4期2卷 103-107页

作者： akira saito Hidehiko Minakawa Noriko saito Tatsumi Nagahashi Department of Plastic and Reconstructive Surgery Graduate School of Medicine Hokkaido University Sapporo Japan Division of Head and Neck Surgery Hokkaido Cancer Center Sapporo Japan Division of Plastic and Reconstructive Surgery Hokkaido Cancer Center Sapporo Japan

The pectoralis major musculocutaneous (PMMC) flap has been a useful technique for head and neck reconstruction since its first description by Ariyan in 1979. However, techniques in microvascular surgery have since evolved and recently free tissue transfer has played an important role in head and neck reconstruction. Although we use free flaps as the first choice for head and neck reconstruction, similar to many other institutions, some patients at our hospital have undergone reconstruction with PMMC flaps. We retrospectively analyzed the indications and outcomes of this reconstructive technique from our experience with 12 patients. The medical records of all patients who underwent PMMC flaps at Hokkaido Cancer Center from 2001 to 2010 were reviewed. Data concerning diagnosis, main indication, site of reconstruction, previous treatment, and postoperative complications were analyzed. Of the 12 PMMC flap surgeries performed, 3 were carried out as primary reconstructive procedures, whereas 9 were done as “salvage” procedures. Flap-related complications were observed in 6 cases. Partial flap loss developed in 4 patients, although there were no cases of total flap loss. There were 3 recurrent fistulae following reconstruction with PMMC flaps. The preoperative goals of performing PMMC flap surgery were met in 83% of our cases. The authors conclude that while free flap transfer is usually the first choice for head and neck reconstruction, PMMC flaps can produce acceptable results in certain situations.

Journal of Thermal Science 2024年第3期33卷 847-855页

A dispersion system fluid can convect even if the dispersoid is a solid phase.Therefore,heat exchange performance can be improved while maintaining fluidity using a material with high thermal conductivity as the dispersoid.This study presents the melting performance evaluation results of a latent heat storage material with a carbon nanotube(CNT)dispersion system with high thermal conductivity,which enhances the thermal conductivity of the latent heat storage material and does not limit free convection.Increasing the thermal conductivity and enhancing the melting convection of the heat storage material result in increased latent heat storage speed.In this study,the thermal conductivity of the latent heat storage material was successfully increased by dispersing CNTs in the material.When 0.1%(in mass)of multi-wall CNT(MWCNT)was dispersed in a paraffin-based latent heat storage material,the shear stress increased by 1.5 times at a shear rate of 500 s^(-1),while taking into account the potential effects of convective inhibition.Therefore,a latent heat storage experiment was conducted in a rectangular heat storage tank using the CNT dispersion composition ratio as a parameter.A rectangular vessel with a heated vertical surface was used for the latent heat storage experiment.The melting speed was determined by comparing the amount of latent heat stored in a CNT-dispersed latent heat storage material and a single-phase latent heat storage material sample.The experimental results show that the time required for the latent heat storage material to completely melt in the heat storage tank was the shortest for the single-phase latent heat storage material sample.However,the fastest melting progress was observed for the sample with 0.02%(in mass)MWCNT content in the melting rate range of up to approximately 40%in the tank.The results indicate that this phenomenon is caused by the difference in the melting rates in the upper part of the tank.The generated data are useful for determining the shape and heat transfer surface arr

World Journal of Transplantation 2024年第2期14卷 155-161页

BACKGROUND Lung transplantation is a well-established treatment of end-stage lung disease.A rodent model is an inexpensive way to collect biological data from a living model after lung transplantation.However,mastering the surgical technique takes time owing to the small organ size.AIM To conduct rat lung transplantation using a shunt cannula(SC)or modified cannula(MC)and assess their efficacy.METHODS Rat lung transplantation was performed in 11 animals in the SC group and 12 in the MC group.We devised a method of rat lung transplantation using a coronary SC for coronary artery bypass surgery as an anastomosis of pulmonary arteri-ovenous vessels and bronchioles.The same surgeon performed all surgical proce-dures in the donor and recipient rats without using a magnifying glass.The success rate of lung transplantation,operating time,and PaO2 values were com-pared after 2-h reperfusion after transplantation.RESULTS Ten and 12 lungs were successfully transplanted in the SC and MC groups,respectively.In the SC group,one animal had cardiac arrest within 1 h after reperfusion owing to bleeding during pulmonary vein anastomosis.The opera-ting time for the removal of the heart-lung block from the donor and preparation of the left lung graft was 26.8±2.3 and 25.7±1.3 min in the SC and MC groups,respectively(P=0.21).The time required for left lung transplantation in the recipients was 37.5±2.8 min and 35.9±1.4 min in the SC and MC groups,respectively(P=0.12).PaO2 values at 2 h after reperfusion were 456.2±25.5 and INTRODUCTION Lung transplantation is a well-established treatment of end-stage lung disease.Many immune and non-immune mech-anisms in lung transplantation are highly complex,and post-transplant complications such as infections and primary and chronic lung allograft dysfunction must be reduced to improve survival.Therefore,there is a need for immunological and pathophysiological analyses using animal lung transplantation models.The rat lung transplantation model was first reported in 1971[1],followed by the Mizuta

Retting has been employed to extract natural fibers from agricultural wastes as a biological and cost-effective approach for centuries.With its global abundance,banana pseudo-stem is a promising agro-waste for lignocellulosic fiber extraction.In this study,fibers were extracted from the pseudo-stems after being pre-treated under four conditions using seawater at room temperature for up to 35 d Bacterial isolation from the fresh seawater sample and screening for ligninolytic ability were conducted.Bacterial load as well as laccase and manganese peroxidase enzyme activity profile assay during the retting duration were analyzed.Fourier transform infrared(FT-IR)and X-day diffraction(XRD)analyses were also examined for both pre-treated and untreated extracted fibers.The results shows that six out of the eight bacterial isolates had the ability to degrade lignin.The treatments(Raw stem+Raw seawater)and(Autoclaved stem+Raw seawater)recorded the highest viable bacterial load of 9.24×102 and 4.46×102 CFU,respectively,on the 14th day of the retting process.Additionally,the highest laccase and manganese peroxidase enzymes activity was recorded for(Raw stem+Raw seawater)and(Autoclaved stem+Raw seawater)treatments in the second to the third week.The FT-IR spectra of the pre-treated fibers revealed relative reductions in peaks attributed to polysaccharides and other amorphous substances for all retting conditions.The XRD diffractogram revealed that the crystallinity index(CI)of pre-treated fibers increased in all seawater retting treatment conditions.However,the CI for fibers pre-treated under enzymatic conditions were enhanced even after five weeks.Sequence analysis for selected bacterial isolates showed homology to sequences of Bacillus velezensis,Shewanella sp.L8–5,and Citrobacter amalonaticus and Bacillus subtilis j8 strain.From these findings,it was suggested that physical,biological,and chemical actions were collectively involved in the seawater retting process of banana pseudo-stems.

Assessment of corrected time-step method for nominal ionospheric gradient calculation: A comparative analysis with spatial approaches

Earth and Planetary Physics 2024年第4期8卷 641-649页

The effect of ionospheric delay on the ground-based augmentation system under normal conditions can be mitigated by determining the value of the nominal ionospheric gradient(σvig).The nominal ionospheric gradient is generally obtained from Continuously Operating Reference Stations data by using the spatial single-difference method(mixed-pair,station-pair,or satellite-pair)or the temporal single-difference method(time-step).The time-step method uses only a single receiver,but it still contains ionospheric temporal variations.We introduce a corrected time-step method using a fixed-ionospheric pierce point from the geostationary equatorial orbit satellite and test it through simulations based on the global ionospheric model.We also investigate the effect of satellite paths on the corrected time-step method in the region of the equator,which tends to be in a more north–south direction and to have less coverage for the east–west ionospheric gradient.This study also addresses the limitations of temporal variation correction coverage and recommends using only the correction from self-observations.All processes are developed under simulations because observational data are still difficult to obtain.Our findings demonstrate that the corrected time-step method yieldsσvig values consistent with other approaches.

众所周知,观音(Avalokitesvara,观自在)是'大乘'佛教的代表性菩萨之一。对于观音的信仰盛行于佛教特别是大乘佛教流布的亚洲各地。观音被认为可以变化身形、救度呻吟于苦难中的众生,所以有六观音、七观音、三十三观音以及与娘娘神等地母神信仰相结合的送子观音等。在日本的民间信仰中,很早就有以'西国三十三所'所代表的观音巡礼的信仰形态。对于佛教流布的诸地所见的多种多样的观音,学界从图像、造型、信仰等方面已经进行了诸多研究。尽管如此,对于观音(观自在)的名称、涵义。
