2Structure and function of aggrecan显示文摘Aggrecan is the major proteoglycan in the articular cartilage. This molecule is important in the proper functioning of articular cartilage because it provides a hydrated gel structure (via its interaction with hyaluronan and link protein) that endows the cartilage with load-bearing properties. It is also crucial in chondroskeletal morphogenesis during development. Aggrecan is a multimodular molecule expressed by chondrocytes. Its core protein is composed of three globular domains (G1, G2, and G3) and a large extended region (CS) between G2 and G3 for glycosaminoglycan chain attachment. G1 comprises the amino terminus of the core protein. This domain has the same structural motif as link protein. Functionally, the G1 domain interacts with hyaluronan acid and link protein, forming stable ternary complexes in the extracellular matrix. G2 is homologous to the tandem repeats of G1 and of link protein and is involved in product processing. G3 makes up the carboxyl terminus of the core protein. It enhances glycosaminoglycan modification and product secretion. Aggrecan plays an important role in mediating chondrocyte-chondrocyte and chondrocyte-matrix interactions through its ability to bind hyaluronan.CHRIS KIANI, LIWEN CHEN, YAO JIONG WU, ALBERT J YEE, BURTON B YANG, Sunnybrook and Women’s College Health Sciences Centre and Department of Laboratory Medicine and Patobiology, 2 Department of Surgeny, Faculty of Medicine, University of Toronto, Canada 2002Cell Research2002,12,1:27
3Prunus genetics and applications after de novo genome sequencing:achievements and prospects显示文摘Prior to the availability of whole-genome sequences,our understanding of the structural and functional aspects of Prunus tree genomes was limited mostly to molecular genetic mapping of important traits and development of EST resources.With public release of the peach genome and others that followed,significant advances in our knowledge of Prunus genomes and the genetic underpinnings of important traits ensued.In this review,we highlight key achievements in Prunus genetics and breeding driven by the availability of these whole-genome sequences.Within the structural and evolutionary contexts,we summarize:(1)the current status of Prunus whole-genome sequences;(2)preliminary and ongoing work on the sequence structure and diversity of the genomes;(3)the analyses of Prunus genome evolution driven by natural and man-made selection;and(4)provide insight into haploblocking genomes as a means to define genome-scale patterns of evolution that can be leveraged for trait selection in pedigree-based Prunus tree breeding programs worldwide.Functionally,we summarize recent and ongoing work that leverages whole-genome sequences to identify and characterize genes controlling 22 agronomically important Prunus traits.These include phenology,fruit quality,allergens,disease resistance,tree architecture,and self-incompatibility.Translationally,we explore the application of sequence-based marker-assisted breeding technologies and other sequence-guided biotechnological approaches for Prunus crop improvement.Finally,we present the current status of publically available Prunus genomics and genetics data housed mainly in the Genome Database for Rosaceae(GDR)and its updated functionalities for future bioinformatics-based Prunus genetics and genomics inquiry.Maria JoséAranzana Véronique Decroocq Elisabeth Dirlewanger Iban Eduardo Zhong Shan Gao Ksenija Gasic Amy Iezzoni Sook Jung Cameron Peace Humberto Prieto Ryutaro Tao Ignazio Verde Albert G.Abbott Pere Arús 2019Horticulture Research2019,6,1:8

8Diabetes mellitus, revascularization and outcomes in elderly patients with myocardial infarction-related cardiogenic shock显示文摘Background The prognostic role of diabetes mellitus(DM)in elderly patients with myocardial infarction-related cardiogenic shock(MI-CS)remains controversial.Little information exists about the impact of intensive cardiac care unit(ICCU)and revascularization on outcomes of elderly patients with MI-CS.We aimed to assess the prognostic impact of DM according to age in patients with MI-CS,and to analyze the impact ICCU management and revascularization on in-hospital mortality in MI-CS patients at older ages.Methods Discharge episodes with diagnosis of CS associated with MI were selected from the Spanish National Health System’s Basic Data Set.Centers were classified according to their availability of ICCU.Main outcome measured was in-hospital mortality.Results A total of 23,590 episodes of MI-CS were identified,of whom 12,447(52.8%)were in patients aged≥75 years.The impact of DM on in-hospital mortality was different among age subgroups.While in younger patients,DM was associated to a higher mortality risk(0.52 vs.0.47,OR=1.12,95%CI:1.06–1.18,χ^2<0.001),this association became non-significant in older patients(0.76 vs.0.81,χ^2=0.09).Adjusted mortality rate of MI-CS aged≥75 years was lower in patients admitted to hospitals with ICCU(adjusted mortality rate:74.2%vs.77.7%,P<0.001)and in patients undergoing revascularization(74.9%vs.77.3%,P<0.001).Conclusions Prognostic impact of DM in patients with MI-CS was different according to age,with a significantly lower impact at older ages.The availability of ICCU and revascularization were associated with better outcomes in these complex patients.Miquel Gual Albert Ariza-Solé María García Márquez Cristina Fernández JoséL Bernal Francesc Formiga María-Isabel Barrionuevo JoséC Sánchez-Salado Victòria Lorente Júlia Pascual Isaac Llaó Oriol Alegre Angel Cequier Javier Elola 2020Journal of Geriatric Cardiology2020,17,10:2
9Correlation between the proportion of breast volume involved by locally advanced tumors and invasion of the skin and posterior structures显示文摘AIM: To evaluate any differences between the percentages of involved breast volume, pathologic attributes,and tumor marker expression of T3 and T4a-c tumors in locally advanced breast cancers(BC).METHODS: All patients with T3 N > 0 and T4a-c BC without evidence of distant metastasis(M0), presenting to the Breast Clinic from 1980 to 2010, were examinedto determine whether their BC's involved ≥ 50% of their breast volumes, defined by gross replacement of at least one hemisphere. Core needle biopsy or postmastectomy specimens from tumors involving a known percent of breast volume were evaluated for:(1)pathological grades and lympho-vascular invasion(LVI);(2) hormone receptor(ER/PR) expression > 0; and(3)epidermoid growth factor 2(her2) over-expression(3+)by immune-histochemical staining or fluorescent in situ hybridization.RESULTS: The data base included 98 patients with T3N> 0 M0 and 120 with T4a-c, any N disease, M0 disease. T3 tumor masses involved 50% or more of the breast in 23/98(24%), and T4a-c tumors 65/120(54%)(P < 0.001). Only 1% of T3 tumors and 23% of T4a-c tumors presented with total breast replacement. There were no significant differences between the pathological attributes and marker expression of the T3 and T4a-c tumors.CONCLUSION: These data suggest that erosion of the overlying skin or underlying chest wall by some BC may be due to neglect and delay, rather than inherent biological aggressiveness.Parastoo B Dahi Komal P Dhiran Constantine A Axiotis Jeremy Weedon Mahmoud El-Tamer Gurinder Sidhu Albert S Braverman 2012World Journal of Clinical Oncology2012,3,3:2

11Evaluation of mannitol effect in patients with acute hepatic failure and acute-on-chronic liver failure using conventional MRI,diffusion tensor imaging and in-vivo proton MR spectroscopy显示文摘AIM:To evaluate the effect of an intravenous bolus of mannitol in altering brain metabolites, brain water content, brain parenchyma volume, cerebrospinal fluid (CSF) volume and clinical signs in controls and in patients with acute liver failure (ALF) and acute-on-chronic liver failure (ACLF), by comparing changes in conventional magnetic resonance imaging (MRI), in vivo proton magnetic resonance spectroscopy (PMRS) and diffusion tensor imaging (DTI) before and after its infusion.METHODS: Five patients each with ALF and ACLF in grade 3 or 4 hepatic encephalopathy and with clinical signs of raised intracranial pressure were studied along with five healthy volunteers. After baseline MRI, an intravenous bolus of 20% mannitol solution was given over 10 min in controls as well as in patients with ALF and ACLF. Repeat MRI for the same position was acquired 30 min after completing the mannitol injection. RESULTS: No statistically significant difference was observed between controls and patients with ALF and ACLF in metabolite ratios, DTI metrics and brain volume or CSF volume following 45 min of mannitol infusion. There was no change in clinical status at the end of post-mannitol imaging. CONCLUSION: The osmotic effect of mannitol did not result in significant reduction of brain water content, alteration in metabolite ratios or any change in the clinical status of these patients during or within 45 min of mannitol infusion.Vivek A Saraswat Sona Saksena Kavindra Nath Pranav Mandal Jitesh Singh M Albert Thomas Ramkishore S Rathore Rakesh K Gupta 2008World Journal of Gastroenterology2008,14,26:2
12Hepatotoxicity associated with glucosamine and chondroitin sulfate in patients with chronic liver disease显示文摘Glucosamine and chondroitin sulfate are molecules involved in the formation of articular cartilage and are frequently used for symptom relief in patients with arthrosis.These molecules are well tolerated with scarce secondary effects.Very few cases of possible hepatotoxicity due to these substances have been described.The aim of this paper is to report the frequency of presumed glucosamine hepatotoxicity in patients with liver disease.A questionnaire was given to 151 consecutive patients with chronic liver disease of different etiology(mean age 59 years,56.9%women)attended in an outpatient clinic with the aim of evaluating the frequency of consumption of these drugs and determine whether their use coincided with a worsening in liver function test results.Twenty-three patients(15.2%)recognized having taken products containing glucosamine or chondroitin sulfate previously or at the time of the questionnaire.Review of the clinical records and liver function tests identified 2 patients presenting an elevation in aminotransferase values temporarily associated with glucosamine treatment;one of the cases simultaneously presented a skin rash attributed to the drug.Review of these two patients and the cases described in the literature suggest toxicity of glucosamine and chondroitin sulfate.The clinical spectrum is variable,and the mechanism of toxicity is not clear but may involve reactions of hypersensitivity.The consumption of products containing glucosamine and/or chondroitin sulfate is frequent among patients with chronic liver diseases and should be taken into account on the appearance of alterations in liver function tests not explained by the underlying disease.Cristian Cerda Miguel Bruguera Albert Parés 2013World Journal of Gastroenterology2013,19,32:2
