2Encapsulating peritoneal sclerosis显示文摘Encapsulating peritoneal sclerosis(EPS) is a debilitating condition characterized by a fibrocollagenous membrane encasing the small intestine, resulting in recurrent small bowel obstructions. EPS is most commonly associated with long-term peritoneal dialysis, though medications, peritoneal infection, and systemic inflammatory disorders have been implicated. Many cases remain idiopathic. Diagnosis is often delayed given the rarity of the disorder combined with non-specific symptoms and laboratory findings. Although cross-sectional imaging with computed tomography of the abdomen can be suggestive of the disorder, many patients undergo exploratory laparotomy for diagnosis. Mortality approaches 50% one year after diagnosis. Treatment for EPS involves treating the underlying condition or eliminating possible inciting agents(i.e. peritoneal dialysis, medications, infections) and nutritional support, frequently with total parenteral nutrition. EPSspecific treatment depends on the disease stage. In the inflammatory stage, corticosteroids are the treatment of choice, while in the fibrotic stage, tamoxifen may be beneficial. In practice, distinguishing between stages may be difficult and both may be used. Surgical intervention, consisting of peritonectomy and enterolysis, is timeconsuming and high-risk and is reserved for situations in which conservative medical therapy fails in institutions with surgical expertise in this area. Herein we review the available literature of the etiology, pathogenesis, diagnosis, and treatment of this rare, but potentially devastating disease.Christopher J Danford Steven C Lin Martin P Smith Jacqueline L Wolf 2018World Journal of Gastroenterology2018,24,28:13
3Subcycle control of terahertz waveform polarization using all-optically induced transient metamaterials显示文摘Coherent radiation with frequencies ranging from 0.3 to 30 THz has recently become accessible using femtosecond laser technology.These terahertz(THz)waves have already been applied in spectroscopy and imaging and can be manipulated using static optical elements such as lenses,polarizers and filters.However,ultrafast modulation of THz radiation is required as well,for instance,in short-range wireless communication or for preparing shaped THz transients for the coherent control of numerous material excitations.Here,we demonstrate an all-optically created transient metamaterial that allows us to manipulate the polarization of THz waveforms with subcycle switch-on times.The polarization-modulated pulses are potentially interesting for controlling elementary motions such as the vibration of crystal lattices,the rotation of molecules and the precession of spins.N Kamaraju Andrea Rubano Linke Jian Surajit Saha T Venkatesan Jan Notzold R Kramer Campen Martin Wolf Tobias Kampfrath 2014Light(Science & Applications)2014,3,1:5
4Hybrid multi-chip assembly of optical communication engines by in situ 3D nanolithography显示文摘Three-dimensional(3D)nano-printing of freeform optical waveguides,also referred to as photonic wire bonding,allows for efficient coupling between photonic chips and can greatly simplify optical system assembly.As a key advantage,the shape and the trajectory of photonic wire bonds can be adapted to the mode-field profiles and the positions of the chips,thereby offering an attractive alternative to conventional optical assembly techniques that rely on technically complex and costly high-precision alignment.However,while the fundamental advantages of the photonic wire bonding concept have been shown in proof-of-concept experiments,it has so far been unclear whether the technique can also be leveraged for practically relevant use cases with stringent reproducibility and reliability requirements.In this paper,we demonstrate optical communication engines that rely on photonic wire bonding for connecting arrays of silicon photonic modulators to InP lasers and single-mode fibres.In a first experiment,we show an eight-channel transmitter offering an aggregate line rate of 448 Gbit/s by low-complexity intensity modulation.A second experiment is dedicated to a four-channel coherent transmitter,operating at a net data rate of 732.7 Gbit/s-a record for coherent silicon photonic transmitters with co-packaged lasers.Using dedicated test chips,we further demonstrate automated mass production of photonic wire bonds with insertion losses of(0.7±0.15)dB,and we show their resilience in environmental-stability tests and at high optical power.These results might form the basis for simplified assembly of advanced photonic multi-chip systems that combine the distinct advantages of different integration platforms.Matthias Blaicher Muhammad Rodlin Billah Juned Kemal Tobias Hoose Pablo Marin-Palomo Andreas Hofmann Yasar Kutuvantavida Clemens Kieninger Philipp-Immanuel Dietrich Matthias Lauermann Stefan Wolf Ute Troppenz Martin Moehrle Florian Merget Sebastian Skacel Jeremy Witzens Sebastian Randel Wolfgang Freude Christian Koos 2020Light(Science & Applications)2020,9,1:4
5DMP1 prevents osteocyte alterations,FGF23 elevation and left ventricular hypertrophy in mice with chronic kidney disease显示文摘During chronic kidney disease (CKD),alterations in bone and mineral metabolism include increased production of the hormone fibroblast growth factor 23 (FGF23) that may contribute to cardiovascular mortality.The osteocyte protein dentin matrix protein 1 (DMP1) reduces FGF23 and enhances bone mineralization,but its effects in CKD are unknown.We tested the hypothesis that DMP1 supplementation in CKD would improve bone health,prevent FGF23 elevations and minimize consequent adverse cardiovascular outcomes.We investigated DMP1 regulation and effects in wild-type (WT) mice and the Col4a3^-/- mouse model of CKD.Col4a3^-/- mice demonstrated impaired kidney function,reduced bone DMP1 expression,reduced bone mass,altered osteocyte morphology and connectivity,increased osteocyte apoptosis,increased serum FGF23,hyperphosphatemia,left ventricular hypertrophy (LVH),and reduced survival.Genetic or pharmacological supplementation of DMP1 in Col4a3^-/- mice prevented osteocyte apoptosis,preserved osteocyte networks,corrected bone mass,partially lowered FGF23 levels by attenuating NFAT-induced FGF23 transcription,and further increased serum phosphate.Despite impaired kidney function and worsened hyperphosphatemia,DMP1 prevented development of LVH and improved Col4a3^-/- survival.Our data suggest that CKD reduces DMP1 expression,whereas its restoration represents a potential therapeutic approach to lower FGF23 and improve bone and cardiac health in CKD.Corey Dussold Claire Gerber Samantha White Xueyan Wang Lixin Qi Connor Francis Maralee Capella Guillaume Courbon Jingya Wang Chaoyuan Li Jian Q.

6Lipocalin 2 stimulates bone fibroblast growth factor 23 production in chronic kidney disease显示文摘Bone-produced fibroblast growth factor 23(FGF23)increases in response to inflammation and iron deficiency and contributes to cardiovascular mortality in chronic kidney disease(CKD).Neutrophil gelatinase-associated lipocalin(NGAL or lipocalin 2;LCN2 the murine homolog)is a pro-inflammatory and iron-shuttling molecule that is secreted in response to kidney injury and may promote CKD progression.We investigated bone FGF23 regulation by circulating LCN2.At 23 weeks,Col4a3KO mice showed impaired kidney function,increased levels of kidney and serum LCN2,increased bone and serum FGF23,anemia,and left ventricular hypertrophy(LVH).Deletion of Lcn2 in CKD mice did not improve kidney function or anemia but prevented the development of LVH and improved survival in association with marked reductions in serum FGF23.Lcn2 deletion specifically prevented FGF23 elevations in response to inflammation,but not iron deficiency or phosphate,and administration of LCN2 increased serum FGF23 in healthy and CKD mice by stimulating Fgf23 transcription via activation of cAMP-mediated signaling in bone cells.These results show that kidney-produced LCN2 is an important mediator of increased FGF23 production by bone in response to inflammation and in CKD.LCN2 inhibition might represent a potential therapeutic approach to lower FGF23 and improve outcomes in CKD.Guillaume Courbon Connor Francis Claire Gerber Samantha Neuburg Xueyan Wang Emily Lynch Tamara Isakova Jodie LBabitt Myles Wolf Aline Martin Valentin David 2021Bone Research2021,9,3:4
