| 3 | In vivo radiometric analysis of glucose uptake and distribution in mouse bone显示文摘Bone formation and remodeling occurs throughout life and requires the sustained activity of osteoblasts and osteoclasts,particularly during periods of rapid bone growth.Despite increasing evidence linking bone cell activity to global energy homeostasis,little is known about the relative energy requirements or substrate utilization of bone cells.In these studies,we measured the uptake and distribution of glucose in the skeleton in vivo using positron-emitting^(18)F-fluorodeoxyglucose([^(18)F]-FDG) and non-invasive,high-resolution positron emission tomography/computed tomography(PET/CT) imaging and ex vivo autoradiography.Assessment of [^(18)F]-FDG uptake demonstrated that relative to other tissues bone accumulated a significant fraction of the total dose of the glucose analog.Skeletal accumulation was greatest in young mice undergoing the rapid bone formation that characterizes early development.PET/CT imaging revealed that [^(18)F]-FDG uptake was greatest in the epiphyseal and metaphyseal regions of long bones,which accords with the increased osteoblast numbers and activity at this skeletal site.Insulin administration significantly increased skeletal accumulation of [^(18)F]-FDG,while uptake was reduced in mice lacking the insulin receptor specifically in osteoblasts or fed a high-fat diet.Our results indicated that the skeleton is a site of significant glucose uptake and that its consumption by bone cells is subject to regulation by insulin and disturbances in whole-body metabolism. | Meredith L Zoch Diane S Abou Thomas L Clemens Daniel LJ Thorek Ryan C Riddle | 2016 | Bone Research2016,4,1: | 9 |
| 4 | Hematopoietic stem cell-derived adipocytes and fibroblasts in the tumor microenvironment显示文摘The tumor microenvironment(TME) is complex and constantly evolving. This is due, in part, to the crosstalk between tumor cells and the multiple cell types that comprise the TME, which results in a heterogeneous population of tumor cells and TME cells. This review will focus on two stromal cell types, the cancerassociated adipocyte(CAA) and the cancer-associated fibroblast(CAF). In the clinic, the presence of CAAs and CAFs in the TME translates to poor prognosis in multiple tumor types. CAAs and CAFs have an activated phenotype and produce growth factors, inflammatory factors, cytokines, chemokines, extracellular matrix components, and proteases in an accelerated and aberrant fashion. Through this activated state, CAAs and CAFs remodel the TME, thereby driving all aspects of tumor progression, including tumor growth and survival, chemoresistance, tumor vascularization, tumor invasion, and tumor cell metastasis. Similarities in the tumorpromoting functions of CAAs and CAFs suggest that a multipronged therapeutic approach may be necessary to achieve maximal impact on disease. While CAAs and CAFs are thought to arise from tissues adjacent to the tumor, multiple alternative origins for CAAs and CAFs have recently been identified. Recent studies from our lab and others suggest that the hematopoietic stem cell, through the myeloid lineage, may serve as a progenitor for CAAs and CAFs. We hypothesize that the multiple origins of CAAs and CAFs may contribute to the heterogeneity seen in the TME. Thus, a better understanding of the origin of CAAs and CAFs, how this origin impacts their functions in the TME, and thetemporal participation of uniquely originating TME cells may lead to novel or improved anti-tumor therapeutics. | Ying Xiong Lindsay T Mc Donald Dayvia L Russell Ryan R Kelly Katie R Wilson Meenal Mehrotra Adam C Soloff Amanda C LaRue | 2015 | World Journal of Stem Cells2015,7,2: | 6 |
| 5 | Microstructure and mechanical properties of Ti-6Al-4V-5% hydroxyapatite composite fabricated using electron beam powder bed fusion显示文摘A novel, Ti-6 Al-4 V(Ti64)/Hydroxyapatite(HA at 5% by weight concentration) metal/ceramic composite has been fabricated using electron beam powder bed fusion(EPBF) additive manufacturing(AM): specifically, the commercial electron beam melting(EBM?) process. In addition to solid Ti64 and Ti64/5% HA samples, four different unit cell(model) open-cellular mesh structures for the Ti64/5% HA composite were fabricated having densities ranging from 0.68 to 1.12 g/cm^3, and corresponding Young's moduli ranging from 2.9 to 8.0 GPa, and compressive strengths ranging from ~3 to 11 MPa. The solid Ti64/5%HA composite exhibited an optimal tensile strength of 123 MPa, and elongation of 5.5% in contrast to a maximum compressive strength of 875 MPa. Both the solid composite and mesh samples deformed primarily by brittle deformation, with the mesh samples exhibiting erratic, brittle crushing. Solid, EPBF-fabricated Ti64 samples had a Vickers microindentation hardness of 4.1 GPa while the Ti64/5%HA solid composite exhibited a Vickers microindentation hardness of 6.8 GPa. The lowest density Ti64/5%HA composite mesh strut sections had a Vickers microindentation hardness of 7.1 GPa. Optical metallography(OM) and scanning electron microscopy(SEM) analysis showed the HA dispersoids to be highly segregated along domain or grain boundaries, but homogeneously distributed along alpha(hcp) platelet boundaries within these domains in the Ti64 matrix for both the solid and mesh composites. The alpha platelet width varied from ~5 μm in the EPBF-fabricated Ti64 to ~1.1 m for the Ti64/5%HA mesh strut. The precursor HA powder diameter averaged 5 μm, in contrast to the dispersed HA particle diameters in the Ti64/5%HA composite which averaged 0.5 m. This work highlights the use of EPBF AM as a novel process for fabrication of a true composite structure, consisting of a Ti64 matrix and interspersed and exposed HA domains, which to the authors' knowledge has not been reported before. The results also illustrate the prospects not only for fabricating specialized, novel composite bone replacement scaffolds and implants, through the combination of Ti64 and HA, but also prospects for producing a variety of related metal/ceramic composites using EPBF AM. | César A.Terrazas Lawrence E.Murr Diego Bermudez Edel Arrieta David A.Roberson Ryan B.Wicker | 2019 | Journal of Materials Science & Technology2019,35,2: | 4 |

| 7 | 腔内介入治疗血管性勃起功能障碍显示文摘过去一个世纪里,勃起功能障碍(ED)的治疗一直是一件引人关注的事情,涉及到泌尿、心血管以及手术领域的多个学科。随着ED与心血管疾病的相关性被充分证实,血管造影技术已被用来鉴别血管性阳痿。由于腔内血管药物洗脱支架植入术在治疗冠状动脉疾病获得成功,采用该技术来治疗血管性ED已激起了医务人员的浓厚兴趣。最近报道了针对阴茎流入血管狭窄的男性,植入药物洗脱支架绕过病变处动脉已获得了较高的成功率。同样,血管内栓塞治疗静脉闭塞功能障碍也取得了惊人的手术成功率。然而,查阅文献发现动脉介入只推荐应用于治疗年轻的孤立性血管损伤的患者,通常为那些先前经历过创伤的患者。该手术的短期功能恢复没有达到最佳,长期疗效也有待进一步观察。总之,用微创方法治疗勃起功能障碍的希望仍然存在,但是在获得普遍认可之前仍需要进一步的研究。 | Edward D Kim Ryan C Owen Gregory S White Osama O Elkelany Cyrus D Rahnema | 2015 | Asian Journal of Andrology2015,17,1: | 3 |
| 8 | Clinical classification of symptomatic heterotopic pancreas of the stomach and duodenum:A case series and systematic literature review显示文摘BACKGROUND Heterotopic pancreas(HP)is an aberrant anatomic malformation that occurs most commonly in the upper gastrointestinal tract.While the majority of heterotopic pancreatic lesions are asymptomatic,many manifest severe clinical symptoms which require surgical or endoscopic intervention.Understanding of the clinical manifestations and symptoms of HP is limited due to the lack of large volume studies in the literature.The purpose of this study is to review symptomatic cases at a single center and compare these to a systematic review of the literature in order to characterize common clinical manifestations and treatment of this disease.AIM To classify the common clinical manifestations of heterotopic pancreas.METHODS A retrospective review was conducted of pathologic samples containing heterotopic pancreas from 2000-2018.Review was limited to HP of the upper gastrointestinal tract due to the frequency of presentation in this location.Symptomatic patients were identified from review of the medical records and clinical symptoms were tabulated.These were compared to a systematic review of the literature utilizing Pub Med and Embase searches for papers pertaining to heterotopic pancreas.Publications describing symptomatic presentation of HP were selected for review.Information including demographics,symptoms,presentation and treatment were compiled and analyzed.RESULTS Twenty-nine patient were identified with HP at a single center,with six of these identified has having clinical symptoms.Clinical manifestations included,gastrointestinal bleeding,gastric ulceration with/without perforation,pancreatitis,and gastric outlet obstruction.Systemic review of the literature yielded 232 publications detailing symptomatic cases with only 20 studies describing ten or more patients.Single and multi-patient studies were combined to form a cohort of 934 symptomatic patients.The majority of patients presented with abdominal pain(67%)combined with one of the following clinical categories:(1)Dyspepsia,(n=445,48%);(2)Pancreatitis(n=260,28%);(3)Gastrointestinal bleeding(n=80,9%);and(4)Gastric outlet obstruction(n=80,9%).The majority of cases(n=832,90%)underwent surgical or endoscopic resection with 85%reporting resolution or improvement in their symptoms.CONCLUSION Heterotopic pancreas can cause significant clinical symptoms in the upper gastrointestinal tract.Better understanding and classification of this disease may result in more accurate identification and treatment of this malformation. | Michael T Le Compte Brandon Mason Keenan J Robbins Motoyo Yano Deyali Chatterjee Ryan C Fields Steven M Strasberg William G Hawkins | 2022 | World Journal of Gastroenterology2022,28,14: | 3 |

| 12 | Percutaneous transluminal angioplasty balloons for endoscopic ultrasound-guided pancreatic duct interventions显示文摘BACKGROUND Endoscopic ultrasound(EUS)-guided main pancreatic duct(PD)access may be used when conventional endoscopic retrograde cholangiopancreatography(ERCP)techniques fail.The use of a percutaneous transluminal angioplasty balloon(PTAB),originally developed for vascular interventions,can be used to facilitate transmural(e.g.,transgastric)PD access and to dilate high-grade pancreatic strictures.AIM To describe the technique,efficacy,and safety of PTABs for EUS-guided PD interventions.METHODS Patients who underwent EUS with use of a PTAB from March 2011 to August 2021 were retrospectively identified from a tertiary care medical center supply database.PTABs included 3-4 French angioplasty catheters with 3-4 mm balloons designed to use over a 0.018-inch guidewire.The primary outcome was technical success.Secondary outcomes included incidence of adverse events(AEs)and need for early reintervention.RESULTS A total of 23 patients were identified(48%female,mean age 55.8 years).Chronic pancreatitis was the underlying etiology in 13(56.5%)patients,surgically altered anatomy(SAA)with stricture in 7(30.4%),and SAA with post-operative leak in 3(13.0%).Technical success was achieved in 20(87%)cases.Overall AE rate was 26%(n=6).All AEs were mild and included 1 pancreatic duct leak,2 cases of post-procedure pancreatitis,and 3 admissions for post-procedural pain.No patients required early re-intervention.CONCLUSION EUS-guided use of PTABs for PD access and/or stricture management is feasible with an acceptable safety profile and can be considered in patients when conventional ERCP cannulation fails. | Jad P AbiMansour Barham K Abu Dayyeh Michael J Levy Andrew C Storm John A Martin Bret T Petersen Ryan J Law Mark D Topazian Vinay Chandrasekhara | 2022 | World Journal of Gastrointestinal Endoscopy2022,14,8: | 2 |

| 15 | Serum-circulating His-tRNA synthetase inhibits organ-targeted immune responses显示文摘His-tRNA synthetase (HARS) is targeted by autoantibodies in chronic and acute inflammatory anti-Jo-1-positive antisynthetase syndrome. The extensive activation and migration of immune cells into lung and muscle are associated with interstitial lung disease, myositis, and morbidity. It is unknown whether the sequestration of HARS is an epiphenomenon or plays a causal role in the disease. Here, we show that HARS circulates in healthy individuals, but it is largely undetectable in the serum of anti-Jo-1-positive antisynthetase syndrome patients. In cultured primary human skeletal muscle myoblasts (HSkMC), HARS is released in increasing amounts during their differentiation into myotubes. We further show that HARS regulates immune cell engagement and inhibits CD4+ and CD8+ T-cell activation. In mouse and rodent models of acute inflammatory diseases, HARS administration downregulates immune activation. In contrast, neutralization of extracellular HARS by high-titer antibody responses during tissue injury increases susceptibility to immune attack, similar to what is seen in humans with anti-Jo-1-positive disease. Collectively, these data suggest that extracellular HARS is homeostatic in normal subjects, and its sequestration contributes to the morbidity of the anti-Jo-1-positive antisynthetase syndrome. | Ryan AAdams Cátia Fernandes-Cerqueira Antonella Notarnicola Elisabeth Mertsching Zhiwen Xu Wing-Sze Lo Kathleen Ogilvie Kyle PChiang Jeanette Ampudia Sanna Rosengren Andrea Cubitt David JKing John DMendlein Xiang-Lei Yang Leslie ANangle Ingrid ELundberg Per-Johan Jakobsson Paul Schimmel | 2021 | Cellular & Molecular Immunology2021,18,6: | 2 |
| 16 | Hypoxia-inducible factor-1a restricts the anabolic actions of parathyroid hormone显示文摘The hypoxia inducible factors(Hifs) are evolutionarily conserved transcriptional factors that control homeostatic responses to low oxygen. In developing bone, Hif-1 generated signals induce angiogenesis necessary for osteoblast specification, but in mature bone, loss of Hif-1 in osteoblasts resulted in a more rapid accumulation of bone. These findings suggested that Hif-1 exerts distinct developmental functions and acts as a negative regulator of bone formation. To investigate the function of Hif-1a in osteoanabolic signaling, we assessed the effect of Hif-1a loss-of-function on bone formation in response to intermittent parathyroid hormone(PTH). Mice lacking Hif-1a in osteoblasts and osteocytes form more bone in response to PTH, likely through a larger increase in osteoblast activity and increased sensitivity to the hormone. Consistent with this effect, exposure of primary mouse osteoblasts to PTH resulted in the rapid induction of Hif-1a protein levels via a post-transcriptional mechanism. The enhanced anabolic response appears to result from the removal of Hif-1a-mediated suppression of b-catenin transcriptional activity. Together, these data indicate that Hif-1a functions in the mature skeleton to restrict osteoanabolic signaling. The availability of pharmacological agents that reduce Hif-1a function suggests the value in further exploration of this pathway to optimize the therapeutic benefits of PTH. | Julie L Frey David P Stonko Marie-Claude Faugere Ryan C Riddle | 2014 | Bone Research2014,2,1: | 2 |
