BACKGROUND The prevalence of heart failure(HF)increases with age,and it is one of the leading causes of hospitalization and death in older patients.However,there are little data on in-hospital mortality in patients with HF≥75 years in Spain.METHODS A retrospective analysis of the Spanish Minimum Basic Data Set was performed,including all HF episodes discharged from public hospitals in Spain between 2016 and 2019.Coding was performed using the International Classification of Diseases,10th Revision.Patients≥75 years with HF as the principal diagnosis were selected.We calculated:(1)the crude in-hospital mortality rate and its distribution according to age and sex;(2)the risk-standardized in-hospital mortality ratio;and(3)the association between in-hospital mortality and the availability of an intensive cardiac care unit(ICCU)in the hospital.RESULTS We included 354,792 HF episodes of patients over 75 years.The mean age was 85.2±5.5 years,and 59.2%of patients were women.The most frequent comorbidities were renal failure(46.1%),diabetes mellitus(35.5%),valvular disease(33.9%),cardiorespiratory failure(29.8%),and hypertension(26.9%).In-hospital mortality was 12.7%,and increased with age[odds ratio(OR)=1.07,95%CI:1.07–1.07,P<0.001]and was lower in women(OR=0.96,95%CI:0.92–0.97,P<0.001).The main predictors of mortality were the presence of cardiogenic shock(OR=19.5,95%CI:16.8–22.7,P<0.001),stroke(OR=3.5,95%CI:3.0–4.0,P<0.001)and advanced cancer(OR=2.6,95%CI:2.5–2.8,P<0.001).In hospitals with ICCU,the in-hospital risk-adjusted mortality tended to be lower(OR=0.85,95%CI:0.72–1.00,P=0.053).CONCLUSIONS In-hospital mortality in patients with HF≥75 years between 2016 and 2019 was 12.7%,higher in males and elderly patients.The main predictors of mortality were cardiogenic shock,stroke,and advanced cancer.There was a trend toward lower mortality in centers with an ICCU.

The distribution of many plant species has been shaped by climate changes,and their current phenotypic and genetic variability refect microclimatically suitable habitats.This study relates contemporary climate to variability patterns of phenotypic traits and molecular markers in the Argentinean distribution of Anadenanthera colubrina var.cebil,as well as to identify the most relevant phenotypic trait or molecular marker associated with those patterns.Individuals from four populations in both biogeographic provinces,Paranaense and Yungas,were investigated.Multivariate analyses and multiple linear regressions were carried out to determine relationships among phenotypic traits and nuclear microsatellites,respectively,to climatic variables,and to identify the phenotypic traits as well as nuclear microsatellite loci most sensitive to climate.Two and three clusters of individuals were detected based on genetic and phenotypic data,respectively.Only clusters based on genetic data refected the biogeographic origin of individuals.Reproductive traits were the most relevant indicators of climatic effects.One microsatellite locus Ac41.1 appeared to be non-neutral presenting a strong correlation with climate variable temperature seasonality.Our findings show complex patterns of genetic and phenotypic variability in the Argentinean distribution of A.colubrina var.cebil related to the present or contemporary climate,and provides an example for an integrative approach to better understand climate impact on contemporary genetic and phenotypic variability in light of global climate change.

Neural Regeneration Research 2023年第3期18卷 478-484页

Parkinson’s disease is a neurodegenerative condition characterized by motor impairments caused by the selective loss of dopaminergic neurons in the substantia nigra.Levodopa is an effective and well-tolerated dopamine replacement agent.However,levodopa provides only symptomatic improvements,without affecting the underlying pathology,and is associated with side effects after long-term use.Cell-based replacement is a promising strategy that offers the possibility to replace lost neurons in Parkinson’s disease treatment.Clinical studies of transplantation of human fetal ventral mesencephalic tissue have provided evidence that the grafted dopaminergic neurons can reinnervate the striatum,release dopamine,integrate into the host neural circuits,and improve motor functions.One of the limiting factors for cell therapy in Parkinson’s disease is the low survival rate of grafted dopaminergic cells.Different factors could cause cell death of dopaminergic neurons after grafting such as mechanical trauma,growth factor deprivation,hypoxia,and neuroinflammation.Neurotrophic factors play an essential role in the survival of grafted cells.However,direct,timely,and controllable delivery of neurotrophic factors into the brain faces important limitations.Different types of cells secrete neurotrophic factors constitutively and co-transplantation of these cells with dopaminergic neurons represents a feasible strategy to increase neuronal survival.In this review,we provide a general overview of the pioneering studies on cell transplantation developed in patients and animal models of Parkinson’s disease,with a focus on neurotrophic factor-secreting cells,with a particular interest in mesenchymal stromal cells;that co-implanted with dopaminergic neurons would serve as a strategy to increase cell survival and improve graft outcomes.

Seasonal patterns of wood formation(xylogenesis)remain understudied in mixed pine-oak forests despite their contribution to tree coexistence through temporal niche complementarity.Xylogenesis was assessed in three pine species(Pinus cembroides,Pinus leiophylla,Pinus engelmannii)and one oak(Quercus grisea)coexisting in a semi-arid Mexican forest.The main xylogenesis phases(production of cambium cells,radial enlargement,cell-wall thickening and maturation)were related to climate data considering 5-15-day temporal windows.In pines,cambium activity maximized from mid-march to April as temperature and evaporation increased,whereas cell radial enlargement peaked from April to May and was constrained by high evaporation and low precipitation.Cell-wall thickening peaked from June to July and in August-September as maximum temperature and vapour pressure deficit(VPD)increased.Maturation of earlywood and latewood tracheids occurred in May-June and June-July,enhanced by high minimum temperatures and VPD in P.engelmannii and P.leiophylla.In oak,cambial onset started in march,constrained by high minimum temperatures,and vessel radial enlargement and radial increment maximized in April as temperatures and evaporation increased,whereas early wood vessels matured from May to June as VPD increased.Overall,15-day wet conditions enhanced cell radial enlargement in P.leiophylla and P.engelmannii,whereas early-summer high 15-day temperature and VPD drove cell-wall thickening in P.cembroides.Warm night conditions and high evaporation rates during spring and summer enhanced growth.An earlier growth peak in oak and a higher responsiveness to spring-summer water demand in pines contributed to their coexistence.

The prevalence of non-alcoholic fatty liver disease(NAFLD)is increasing worldwide,reflecting the current epidemics of obesity,insulin resistance,type 2 diabetes mellitus,and metabolic syndrome.NAFLD is characterized by the accumulation of fat in the liver,and is known to be a cause of cirrhosis.Although many pathways have been proposed,the cause of NAFLD-linked fibrosis progression is still unclear,which posed challenges for the development of new therapies to prevent NASH-related cirrhosis and hepatocellular carcinoma.Cirrhosis is associated with activation of hepatic stellate cells(HSC)and accumulation of excess extracellular matrix proteins,and inhibiting the activation of HSCs would be expected to slow the progression of NAFLD-cirrhosis.Multiple molecular signals and pathways such as oxidative stress and glutaminolysis have been reported to promote HSC activation.Both mechanisms are plausible antifibrotic targets in NASH,as the activation of HSCs the proliferation of myofibroblasts depend on those processes.This review summarizes the role of the glutaminolysis-ammonia-urea cycle axis in the context of NAFLD progression,and shows how the axis could be a novel therapeutic target.

Advanced mesenchymal stromal cell-based therapies for neurodegenerative diseases are widely investigated in preclinical models.Mesenchymal stromal cells are well positioned as therapeutics because they address the underlying mechanisms of neurodegeneration,namely trophic factor deprivation and neuroinflammation.Most studies have focused on the beneficial effects of mesenchymal stromal cell transplantation on neuronal survival or functional improvement.However,little attention has been paid to the interaction between mesenchymal stromal cells and the host immune system due to the immunomodulatory properties of mesenchymal stromal cells and the long-held belief of the immunoprivileged status of the central nervous system.Here,we review the crosstalk between mesenchymal stromal cells and the immune system in general and in the context of the central nervous system,focusing on recent work in the retina and the importance of the type of transplantation.

Lowering nitrogen inputs is a major goal for sustainable agriculture.In the present study,a set of 10 Solanum melongena introgression lines(ILs)developed using Solanum incanum as the exotic donor parent were grown under two nitrogen fertilization doses supplied with the irrigation system:1)8.25 mmol·L-1NH4NO3,corresponding to the high nitrogen treatment(HN),and 2)no external nitrogen supply,corresponding to the low nitrogen treatment(LN).Twenty traits,including plant growth and yield parameters,fruit size and morphology,nitrogen and carbon content in leaf and fruit,and phenolics content in fruit,were evaluated.The aim was to select of potential materials for eggplant breeding under low N inputs,as well as to identify and locate putative QTLs associated with the traits evaluated.No significant differences were observed between the soil characteristics of the HN and LN treatments,except for nitrogen and iron content,which was slightly lower in the HN,probably as a consequence of higher nutrient removal from soil by plants in the latter group.Analysis of variance showed that lowering nitrogen inputs did not significantly affect the final yield,fruit morphology,size and phenolics content.Most agronomic traits were highly and positively correlated with each other under both treatments,as well as total phenolics with chlorogenic acid content.The assessment of the differences between each IL and the recipient parent resulted in the identification of 36 QTLs associated with most of the traits—12 were specific to the HN,17 specific to the LN,and 7 were stable across treatments.The introgressed fragment of S.incanum generally had a negative effect on the trait,except for QTLs for fruit dry matter,for fruit length on chromosome 10 under the HN,and for fruit pedicel length on chromosome 9 under the LN.The increase over AN-S-26 of the allele of S.incanum for the QTLs detected ranged between-73.98% and 26.03% in HN and-73.67%and 34.43% in LN.These findings provide useful tools for the utilization of S.incanum in eggplant breed

Background The Ibizan Hound is a canine breed native to the Mediterranean region,where leishmaniasis is an endemic zoonosis.Several studies indicate a low prevalence of this disease in Ibizan Hound dogs,whereas other canine breeds present a high prevalence.However,the underlying molecular mechanisms still remain unknown.The aim of this work is to analyse the relationship between serum levels of cytokines and the genomic profiles in two canine breeds,Ibizan Hound(resistant canine breed model)and Boxer(susceptible canine breed model).Methods In this study,we analyse the haplotypes of genes encoding cytokines related to immune response of Leishmania infantum infection in twenty-four Boxers and twenty-eight Ibizan Hounds apparently healthy using CanineHD DNA Analysis BeadChip including 165,480 mapped positions.The haplo.glm extension of haplo.score was used to perform a General Linear Model(GLM)regression to estimate the magnitude of individual haplotype effects within each cytokine.Results Mean levels of interferon gamma(IFN-γ),interleukin 2(IL-2)and IL-18 in Boxer dogs were 0.19±0.05 ng/ml,46.70±4.54 ng/ml,and 36.37±30.59 pg/ml,whereas Ibizan Hound dogs present 0.49±0.05 ng/ml,64.55±4.54 ng/ml,and 492.10±31.18 pg/ml,respectively.The GLM regression shows fifteen haplotypes with statistically significant effect on the cytokine serum levels(P<0.05).The more relevant are IL6-CGAAG and IFNG-GCA haplotypes,which increase and decrease the IL-2,IL-8 and IFN-γserum levels,respectively.Conclusions Haplotypes in the IFNG and IL6 genes have been correlated to serum levels of IFN-γ,IL-2 and IL-18,and a moderate effect has been found on IL8 haplotype correlated to IL-8 and IL-18 serum levels.The results indicate that the resistance to L.infantum infection could be a consequence of certain haplotypes with a high frequency in the Ibizan Hound dog breed,while susceptibility to the disease would be related to other specific haplotypes,with high frequency in Boxer.Future studies are needed to elucidate whether these differences and h

The use of unmanned aerial vehicles(UAV)for forest monitoring has grown significantly in recent years,providing information with high spatial resolution and temporal versatility.UAV with multispectral sensors allow the use of indexes such as the normalized difference vegetation index(NDVI),which determines the vigor,physiological stress and photo synthetic activity of vegetation.This study aimed to analyze the spectral responses and variations of NDVI in tree crowns,as well as their correlation with climatic factors over the course of one year.The study area encompassed a 1.6-ha site in Durango,Mexico,where Pinus cembroides,Pinus engelmannii,and Quercus grisea coexist.Multispectral images were acquired with UAV and information on meteorological variables was obtained from NASA/POWER database.An ANOVA explored possible differences in NDVI among the three species.Pearson correlation was performed to identify the linear relationship between NDVI and meteorological variables.Significant differences in NDVI values were found at the genus level(Pinus and Quercus),possibly related to the physiological features of the species and their phenology.Quercus grisea had the lowest NDVI values throughout the year which may be attributed to its sensitivity to relative humidity and temperatures.Although the use of UAV with a multispectral sensor for NDVI monitoring allowed genera differentiation,in more complex forest analyses hyperspectral and LiDAR sensors should be integrated,as well other vegetation indexes be considered.
