Plant growth and development involve the specification and regeneration of stem cell niches(SCNs).Although plants are exposed to disparate environmental conditions,how environmental cues affect developmental programs and stem cells is not well understood.Root stem cells are accommodated in meristems in SCNs around the quiescent center(QC),which maintains their activity.Using a combination of genetics and confocal microscopy to trace morphological defects and correlate them with changes in gene expression and protein levels,we show that the cold-induced transcription factor(TF)C-REPEAT BINDING FACTOR 3(CBF3),which has previously been associated with cold acclimation,regulates root development,stem cell activity,and regeneration.CBF3 is integrated into the SHORT-ROOT(SHR)regulatory network,forming a feedback loop that maintains SHR expression.CBF3 is primarily expressed in the root endodermis,whereas the CBF3 protein is localized to other meristematic tissues,including root SCNs.Complementation of cbf3-1 using a wild-type CBF3 gene and a CBF3 fusion with reduced mobility show that CBF3 movement capacity is required for SCN patterning and regulates root growth.Notably,cold induces CBF3,affecting QC activity.Furthermore,exposure to moderate cold around 10℃–12℃promotes root regeneration and QC respecification in a CBF3-dependent manner during the recuperation period.By contrast,CBF3 does not appear to regulate stem cell survival,which has been associated with recuperation from more acute cold(-4℃).We propose a role for CBF3 in mediating the molecular interrelationships among the cold response,stem cell activity,and development.

Postembryonic organogenesis is critical for plant development.Underground,lateral roots(LRs)form the bulk of mature root systems,yet the ontogeny of the LR primordium(LRP)is not clear.In this study,we performed the single-cell RNA sequencing through the first four stages of LR formation in Arabidopsis.Our analysis led to a model in which a single group of precursor cells,with a cell identity different from their pericycle origins,rapidly reprograms and splits into a mixed ground tissue/stem cell niche fate and a vascular precursor fate.The ground tissue and stem cell niche fates soon separate and a subset of more specialized vascular cells form sucrose transporting phloem cells that appear to connect to the primary root.We did not detect cells resembling epidermis or root cap,suggesting that outer tissues may form later,preceding LR emergence.At this stage,some remaining initial precursor cells form the primordium flanks,while the rest create a reservoir of pluripotent cells that are able to replace the LR if damaged.Laser ablation of the central and lateral LRP regions showed that remaining cells restart the sequence of tissue initiation to form a LR.Collectively,our study reveals an ontological hierarchy for LR formation with an early and sequential split of main root tissues and stem cells.

Stereotactic ablative body radiotherapy(SABR)is an effective technique comparable to surgery in terms of local control and efficacy in early stages of non-small cell lung cancer(NSCLC)and pulmonary metastasis.Several fractionation schemes have proven to be safe and effective,including the single fraction(SF)scheme.SF is an option costeffectiveness,more convenience and comfortable for the patient and flexible in terms of its management combined with systemic treatments.The outbreak of the severe acute respiratory syndrome coronavirus 2 pandemic has driven this not new but underutilized paradigm,recommending this option to minimize patients’visits to hospital.SF SABR already has a long experience,strong evidence and sufficient maturity to reliably evaluate outcomes in peripheral primary NSCLC and there are promising outcomes in pulmonary metastases,making it a valid treatment option;although its use in central locations,synchronous and recurrencies tumors requires more prospective safety and efficacy studies.The SABR radiobiology study,together with the combination with systemic therapies,(targeted therapies and immunotherapy)is a direction of research in both advanced disease and early stages whose future includes SF.

Background:In this study,we aimed to investigate the molecular basis of lactation as well as to identify the genetic factors that influence milk yield and composition in goats.To achieve these two goals,we have analyzed how the mRNA profile of the mammary gland changes in seven Murciano-Granadina goats at each of three different time points,i.e.78 d(T1,early lactation),216 d(T2,late lactation)and 285 d(T3,dry period)after parturition.Moreover,we have performed a genome-wide association study(GWAS)for seven dairy traits recorded in the 1st lactation of 822 Murciano-Granadina goats.Results:The expression profiles of the mammary gland in the early(T1)and late(T2)lactation were quite similar(42 differentially expressed genes),while strong transcriptomic differences(more than one thousand differentially expressed genes)were observed between the lactating(T1/T2)and non-lactating(T3)mammary glands.A large number of differentially expressed genes were involved in pathways related with the biosynthesis of amino acids,cholesterol,triglycerides and steroids as well as with glycerophospholipid metabolism,adipocytokine signaling,lipid binding,regulation of ion transmembrane transport,calcium ion binding,metalloendopeptidase activity and complement and coagulation cascades.With regard to the second goal of the study,the performance of the GWAS allowed us to detect 24 quantitative trait loci(QTLs),including three genome-wide significant associations:QTL1(chromosome 2,130.72-131.01 Mb)for lactose percentage,QTL6(chromosome 6,78.90-93.48 Mb)for protein percentage and QTL17(chromosome 17,11.20 Mb)for both protein and dry matter percentages.Interestingly,QTL6 shows positional coincidence with the casein genes,which encode 80%of milk proteins.Conclusions:The abrogation of lactation involves dramatic changes in the expression of genes participating in a broad array of physiological processes such as protein,lipid and carbohydrate metabolism,calcium homeostasis,cell death and tissue remodeling,as well as immunity.We also conclude that

Malignant pleural mesothelioma(MPM)is a rare tumor with poor prognosis and rising incidence.Palliative care is common in MPM as radical treatment with curative intent is often not possible due to metastasis or extensive locoregional involvement.Numerous therapeutic advances have been made in recent years,including the use of less aggressive surgical techniques associated with lower morbidity and mortality(e.g.,pleurectomy/decortication),technological advancements in the field of radiotherapy(intensity-modulated radiotherapy,image-guided radiotherapy,stereotactic body radiotherapy,proton therapy),and developments in systemic therapies(chemotherapy and immunotherapy).These improvements have had as yet only a modest effect on local control and survival.Advances in the management of MPM and standardization of care are hampered by the evidence to date,limited by high heterogeneity among studies and small sample sizes.In this clinical guideline prepared by the oncological group for the study of lung cancer of the Spanish Society of Radiation Oncology,we review clinical,histologic,and therapeutic aspects of MPM,with a particular focus on all aspects relating to radiotherapy,including the current evidence base,associations with chemotherapy and surgery,treatment volumes and planning,technological advances,and reradiation.

Management of MSW(Municipal Solid Waste)is a major downside in most of the biggest cities.The composting of the organic fraction of MSW is one of the oldest and simplest ways of organic waste stabilization.It is a self-heating biological conversion that generates appropriate finished merchandise such as soil conditioner or fertilizers.Mexico City generates about 12,500 ton/day of MSW,44%of it is food scraps and yard trimmings which are the OFMSW(Organic Fraction of Municipal Solid Waste),2,500 ton/day of it is composted at the BPCP(Bordo Poniente Composting Plant)yielding 500 ton/day of compost.The purpose of this study was to evaluate three treatments to accelerate the composting process,so eventually the city could increase the amount of the OFMSW at BPCP.We compared three different treatments;one of them showed a significant reduction in time of the composting process(p≤0.05)i.e.,it took less time to reach the thermophilic stage,maturity and stabilization phases.Maturity was achieved at 35 days and 60 days to stabilize.We conclude that shredding the feedstock plus leachate inoculum addition at the beginning of the process,reduces the composting time in about 61%with respect to the time it takes at the BPCP,where lasted 90 days.

Formation of Interface Bound States on a Graphene-Superconductor Junction in the Presence of Charge Inhomogeneities

引用

Graphene 2013年第1期2卷 35-41页

作者： Pablo Burset William javier Herrera Alfredo Levy Yeyati Departamento de Física Teórica de la Materia Condensada and Instituto Nicolás cabrera Universidad Autónoma de Madrid Madrid Spain Departamento de Física Universidad Nacional de Colombia Bogotá Colombia

Interface bound states have been theoretically predicted to appear at isolated graphene-superconductor junctions. These states are formed at the interface due to the interplay between virtual Andreev and normal reflections and provide long range superconducting correlations on the graphene layer. We describe in detail the formation of these states from combining the Dirac equation with the Bogoliubov de Gennes equations of superconductivity. On the other hand, fluctuations of the low energy charge density in graphene have been confirmed as the dominating type of disorder. For analyzing the effect of disorder on these states we use a microscopic tight binding model. We show how the formation of these states is robust against the presence of disorder in the form of electron charge inhomogeneities in the graphene layer. We numerically compute the effect of disorder on the interface bound states and on the local density of states of graphene.
