1Vascular endothelial dysfunction, cardiomyopathy a major mediator in diabetic cardiomyopathy显示文摘Diabetes mellitus is currently a major public health problem.A common complication of diabetes is cardiac dysfunction,which is recognized as a microvascular disease that leads to morbidity and mortality in diabetic patients.While ischemic events are commonly observed in diabetic patients,the risk for developing heart failure is also increased,independent of the severity of coronary artery disease and hypertension.This diabetes-associated clinical entity is considered a distinct disease process referred to as 'diabetic cardiomyopathy'.However,it is not clear how diabetes promotes cardiac dysfunction.Vascular endothelial dysfunction is thought to be one of the key risk factors.The impact of diabetes on the endothelium involves several alterations,including hyperglycemia,fatty acid oxidation,reduced nitric oxide (NO),oxidative stress,inflammatory activation,and altered barrier function. The current review provides an update on mechanisms that specifically target endothelial dysfunction,which may lead to diabetic cardiomyopathy.Maura Knapp Xin Tu Rongxue Wu 2019Acta Pharmacologica Sinica2019,40,1:34
2Combined glucocorticoid and antiviral therapy of hepatitis B virus-related liver failure显示文摘Acute hepatic failure due to hepatitis B virus(HBV)can occur both during primary infection as well as after reactivation of chronic infection.Guidelines recommend considering antiviral therapy in both situations,although evidence supporting this recommendation is weak.Since HBV is not directly cytopathic,the mechanism leading to fulminant hepatitis B is thought to be primarily immunemediated.Therefore,immunosuppression combined with antiviral therapy might be a preferred therapeutic intervention in acute liver failure in hepatitis B.Here wereport our favourable experience in three hepatitis B patients with fulminant hepatic failure who were treated by combining high-dose steroid therapy with standard antiviral treatment,which resulted in a rapid improvement of clinical and liver parameters.Jan-Hendrik Bockmann Maura Dandri Stefan Lüth Nadine Pannicke Ansgar W Lohse 2015World Journal of Gastroenterology2015,21,7:13

4Role of endoscopic ultrasonography in the loco-regional staging of patients with rectal cancer显示文摘The prognosis of rectal cancer(RC) is strictly related to both T and N stage of the disease at the time of diagnosis. RC staging is crucial for choosing the best multimodal therapy: patients with high risk locally advanced RC(LARC) undergo surgery after neoadjuvant chemotherapy and radiotherapy(NAT); those with low risk LARC are operated on after a preoperative short-course radiation therapy; finally, surgery alone is recommended only for early RC. Several imaging methods are used for staging patients with RC: computerized tomography, magnetic resonance imaging, positron emission tomography, and endoscopic ultrasound(EUS). EUS is highly accurate for the loco-regional staging of RC, since it is capable to evaluate precisely the mural infiltration of the tumor(T), especially in early RC. On the other hand, EUS is less accurate in restaging RC after NAT and before surgery. Finally, EUS is indicated for follow-up of patients operated on for RC, where there is a need for the surveillance of the anastomosis. The aim of this review is to highlight the impact of EUS on the management of patients with RC, evaluating its role in both preoperative staging and follow-up of patients after surgery.Pietro Marone Mario de Bellis Valentina D'Angelo Paolo Delrio Valentina Passananti Elena Di Girolamo Giovanni Battista Rossi Daniela Rega Maura Claire Tracey Alfonso Mario Tempesta 2015World Journal of Gastrointestinal Endoscopy2015,7,7:11

6Safety and outcomes of cochlear implantation in the elderly:A review of recent literature显示文摘Global demographic changes related to longevity are leading to increasing numbers of the elderly,for whom hearing loss is a significant cause of morbidity and disability.Once met with reticence,severely hearing impaired older adults are increasingly being considered for cochlear implantation(CI).Significant data indicate that CI in the elderly population is safe,well-tolerated,and effective.Risks from CI surgery and anesthesia are low and generally comparable to rates in other age groups.Outcomes studies regarding CI in older adults have shown excellent improvements to speech perception,quality of life,and even cognition.Overall,currently available data suggests that advanced age should not,in itself,be considered a barrier to implantation.This review paper will highlight selected articles from recent medical literature regarding the safety and efficacy of CI in the elderly population.Zao Yang Maura Cosetti 2016Journal of Otology2016,11,1:5
7Hydrogen storage in a rare-earth perovskite-type oxide La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_3 for battery applications显示文摘Recently, rare-earth perovskite-type oxides with the general formula ABO_3(A rare earth element, B transition metal, O oxygen) are regarded as promising materials for Ni/oxide batteries due to their hydrogen storage ability. In the present study, the hydrogen storage properties of the rare-earth perovskite-type oxide La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_3 were evaluated in alkaline solution and at various temperatures. The hydrogen storage properties were investigated electrochemically by applying galvanostatic charge/discharge currents. Electrochemical pressurecomposition-temperature isotherms were constructed using the Nernst equation. The exchange current density and proton hydrogen diffusion coefficient were calculated using linear polarization measurements and the potential-step method, respectively. Interestingly, the maximum hydrogen absorption capacity, re-calculated from the electrochemical capacity, is 1.72 wt% at 333 K and 6 mol·L^(-1)KOH. In addition, the hysteresis value, calculated from pressure-composition-temperature isotherms, was429 J·mol^(-1) at 333 K,while the self-discharge rate was about 25% after 24-h storage at open circuit and at 333 K.John Henao Oscar Sotelo Maura Casales-Diaz Lorenzo Martinez-Gomez 2018Rare Metals2018,37,12:5
8Mobilization of hematopoietic progenitor cells in patients with liver cirrhosis显示文摘AIM:To test the hypothesis that liver cirrhosis is associated with mobilization of hematopoietic progenitor cells. METHODS:Peripheral blood samples from 72 patients with liver cirrhosis of varying etiology were analyzed by flow cytometry.Identified progenitor cell subsets were immunoselected and used for functional assays in vitro. Plasma levels of stromal cell-derived factor-1(SDF-1) were measured using an enzyme linked immunosorbent assay.RESULTS:Progenitor cells with a CD133 + /CD45 + CD14 + phenotype were observed in 61%of th patients.Between 1%and 26%of the peripheral bloo mononuclear cells(MNCs)displayed this phenotype Furthermore,a distinct population of c-kit + progenito cells(between 1%and 38%of the MNCs)could b detected in 91%of the patients.Additionally,18% of the patients showed a population of progenito cells(between 1%and 68%of the MNCs)that wa characterized by expression of breast cancer resistanc protein-1.Further phenotypic analysis disclosed tha the circulating precursors expressed CXC chemokin receptor 4,the receptor for SDF-1.In line with thi finding,elevated plasma levels of SDF-1 were presen in all patients and were found to correlate with th number of mobilized CD133 + progenitor cells.Ursula M Gehling Marc Willems Kathleen Schlagner Ralf A Benndorf Maura Dandri Jrg Petersen Martina Sterneck Joerg-Matthias Pollok Dieter K Hossfeld Xavier Rogiers 2010World Journal of Gastroenterology2010,16,2:4

10The P132H mutation in the main protease of Omicron SARSCoV-2 decreases thermal stability without compromising catalysis or small-molecule drug inhibition显示文摘Dear Editor,The ongoing SARS-CoV-2 pandemic continues to be a significant threat to global health.First reported in November 2021,the Omicron variant(B.1.1.529)is more transmissible and can evade immunity better than previous SARS-CoV-2 variants,fueling an unprecedented surge in cases.To produce functional proteins from its polyprotein,SARS-CoV-2 relies on the cysteine proteases Nsp3/papain-like protease(PLpro)and Nsp5/main protease(Mpro)/3C-like protease to cleave at three and more than 11 sites,respectively.1 Therefore,Mpro and PLpro inhibitors are considered to be one of the most promising SARS-CoV-2 antivirals.On December 22,2021,the Food and Drug Administration(FDA)issued an Emergency Use Authorization(EUA)for PAXLOVID,a ritonavir-boosted formulation of nirmatrelvir.Nirmatrelvir is a first-in-class orally bioavailable SARSCoV-2 Mpro inhibitor.2 Thus,the scientific community must vigilantly monitor potential mechanisms of drug resistance,especially because SARS-CoV-2 is naïve to Mpro inhibitors.Mutations have been well identified in variants to this point.3 Notably,Omicron Mpro(OMpro)harbors a single mutation—P132H.In this study,we characterized the enzymatic activity,drug inhibition,and structure of OMpro while evaluating the past and future implications of Mpro mutations.Michael Dominic Sacco Yanmei Hu Maura Verenice Gongora Flora Meilleur Michael Trent Kemp Xiujun Zhang Jun Wang Yu Chen 2022Cell Research2022,32,5:3

13Histological analysis of pollen-pistil interactions in sour passion fruit plants (Passiflora edulis Sims)显示文摘The success of sexual plant reproduction is directly influenced by specific interactions between the pollen and pistil.Light,fluorescence and scanning electron microscopy techniques were used to evaluate the steps of pollination in sour passion fruit plants(Passiflora edulis Sims).In the compatible interaction,pollen tubes grow through stigma projections towards the ovary.The pollen grain surface was found to be spheroidal and to consist of heteroreticulate exine with six colpi.Furthermore,analysis in vivo of pollenpistil interactions indicated that stigmas of flowers 24 hours before anthesis are unable to discriminate compatible(genetically unrelated)and incompatible(genetically related)pollen grains.Taken together,these results provide insight into the cellular mechanisms underlying pollination in passion fruit plants.HÉRIKA CHAGAS MADUREIRA TELMA NAIR SANTANA PEREIRA MAURA DA CUNHA DENISE ESPELLET KLEIN 2012BIOCELL2012,36,2:2

18Successful treatment of psychosis induced by interferon alpha and ribavirin with paliperidone:first case reported显示文摘Several clinical studies have shown a large number of mental symptoms by immunomodulatory treatment with interferon (IFN). The most frequently described symptoms are depression, suicidal behaviour, manic symptoms, anxiety, psychosis and delirium, associated with other non-specific symptoms such as fatigue, irritability, psychomotor retardation, decreased libido, insomnia, difficulty in concentration and attention. Having a history of mental disorder contraindicates the use of IFN-alpha. These adverse effects that affect the mental state appear usually at the beginning of the treatment (most after 3 weeks of treatment). The incidence of psychotic episodes is low and the episodes usually remit when treatment is interrupted;only some cases require antipsychotic treatment. We present the case of a patient affected with hepatitis C who began to present self-referential delirious symptoms after receiving the treatment with IFN and who was successfully treated with paliperidone. This patient could be classified within the group of high-risk psychiatric patients given the family history of schizophrenia and his personal history of illegal drug consumption. The pharmacological actions of paliperidone are similar to other high potency atypical antipsychotics.丁he receptorbinding profile of paliperidone most closely resembles that of risperidone and ziprasidone. Paliperidone differs from risperidone and most other antipsychotics by its relatively low extent of enzymatic hepatic metabolism. To the best of our knowledge, this is the first case described that was successfully treated with paliperidone.Carmen Maura Carrillo de Albornoz Calahorro Maria Isabel Navarrete Paez Margarita Guerrero Jimenez Luis Gutierrez Rojas 2019General Psychiatry2019,32,4:2
