Background:Ocular surface disease in glaucoma patients is a significant ocular co-morbidity that can affect 40%to 59%of these patients worldwide.The current study was aimed at evaluating the potential clinical benefit of an intense pulsed light(IPL)-based treatment in glaucomatous patients with ocular surface disease due to prolonged hypotensive eyedrop treatments.To our knowledge,this is the first series analyzing the therapeutic effect of this treatment option in this type of patients.Methods:This non-comparative prospective case series study enrolled a total of 30 glaucoma patients ranging in age from 57 to 94 years old and treated with hypotensive eyedrops for years with dry eye symptomatology.All patients received four sessions of IPL treatment using the Optima IPL system(Lumenis,Yokneam,Israel)adjusted to the official optimized Lumenis setting.Changes in symptomatology,corneal staining,conjunctival hyperemia,non-invasive break-up time(NIBUT),tear osmolarity,tear meniscus height(TMH),meiboscore and meibomian gland expressibility was analyzed after treatment.Results:Statistically significant reductions were observed after IPL treatment in the symptomatology scores measured with different questionnaires[ocular surface disease index(OSDI),standard patient evaluation of eye dryness(SPEED)and symptom assessment questionnaire in dry eye(SANDE)]as well as with the visual analogue scale(P<0.001).Mean change in OSDI was−15.0±11.3.A significant reduction was found after treatment in the corneal staining score(P<0.001).A significant reduction was found in tear film meniscus height(P=0.012),as well as in tear film osmolarity(P=0.001).A significant reduction was also found in meibomian gland expressibility(P=0.003),changing the percentage of grade 3 eyes from 44.4%before IPL to 17.2%after treatment.Conclusions:IPL therapy combined with meibomian gland expression(MGX)seems to be an effective option to improve symptomatology in glaucomatous patients with ocular surface disease due to prolonged hypotensive eyedrop treatment

BACKGROUND Liver resection surgery has advanced greatly in recent years,and the adoption of fasttrack programs has yielded good results.Combination anesthesia (general anesthesia associated to epidural analgesia) is an anesthetic-analgesic strategy commonly used for the perioperative management of patients undergoing surgery of this kind,though there is controversy regarding the coagulation alterations it may cause and which can favor the development of spinal hematomas.AIM To study the postoperative course of liver resection surgery,an analysis was made of the outcomes of liver resection surgery due to colorectal cancer metastases in our centre in terms of morbiditymortality and hospital stay according to the anesthetic technique used (general vs combination anesthesia).METHODS A prospective study was made of 61 colorectal cancer patients undergoing surgery due to liver metastases under general and combination anesthesia between January 2014 and October 2015.The patient characteristics,intraoperative variables,postoperative complications,evolution of hemostatic parameters,and stay in intensive care and in hospital were analyzed.RESULTS A total of 61 patients were included in two homogeneous groups: general anesthesia (n = 30) and combination anesthesia (general anesthesia associated to epidural analgesia)(n = 31).All patients had normal coagulation values before surgery.The international normalized ratio (INR) in both the general and combination anesthesia groups reached maximum values at 2448 h (mean 1.37 and 1.45 vs 1.39 and 1.41,respectively),followed by a gradual decrease.There was less intraoperative bleeding in the combination anesthesia group (769 mL) than in the general anesthesia group (1200 mL)(P < 0.05).Of the 61 patients,38.8% in the general anesthesia group experienced some respiratory complication vs 6.6% in the combination anesthesia group (P < 0.001).The time to gastrointestinal tolerance was significantly correlated to the type of anesthesia,though not so the stay in critical care or the time to

Dear Editor,Hereditary prostate cancer(PC)comprises 5%-10%of all PC cases.The increased risk of PC in menwith a family his-tory of the disease is well known and is commonly caused by germline mutations,leading to clinical guidelines men-tioning various genes for identifying high-risk individuals.However,the complex inheritance patterns involvingmul-tiple single nucleotide polymorphisms(SNPs)make it a genetically heterogeneous disease,with genetic testing still in its early stages.

Nitric oxide(NO)is an essential reactive oxygen species and a signal molecule in plants.Although several studies have proposed the occurrence of oxidative NO production,only reductive routes for NO production,such as the nitrate(NO_(3)^(-))-upper-reductase pathway,have been evidenced to date in land plants.However,plants grown axenically with ammonium as the sole source of nitrogen exhibit contents of nitrite and NO3−,evidencing the existence of a metabolic pathway for oxidative production of NO.We hypothesized that oximes,such as indole-3-acetaldoxime(IAOx),a precursor to indole-3-acetic acid,are intermediate oxidation products in NO synthesis.We detected the production of NO from IAOx and other oximes catalyzed by peroxidase(POD)enzyme using both 4-amino-5-methylamino-2′,7′-difluorescein fluorescence and chemiluminescence.Flavins stimulated the reaction,while superoxide dismutase inhibited it.Interestingly,mouse NO synthase can also use IAOx to produce NO at a lower rate than POD.We provided a full mechanism for POD-dependent NO production from IAOx consistent with the experimental data and supported by density functional theory calculations.We showed that the addition of IAOx to extracts from Medicago truncatula increased the in vitro production of NO,while in vivo supplementation of IAOx and other oximes increased the number of lateral roots,as shown for NO donors,and a more than 10-fold increase in IAOx dehydratase expression.Furthermore,we found that in vivo supplementation of IAOx increased NO production in Arabidopsis thaliana wild-type plants,while prx33-34 mutant plants,defective in POD33-34,had reduced production.Our data show that the release of NO by IAOx,as well as its auxinic effect,explain the superroot phenotype.Collectively,our study reveals that plants produce NO utilizing diverse molecules such as oximes,POD,and flavins,which are widely distributed in the plant kingdom,thus introducing a long-awaited oxidative pathway to NO production in plants.This knowledge has essential implications for und

Plant growth is determined by well-defined developmental processes that integrate cell-intrinsic factors and external environmental cues,and it is largely dependent on the assimilation of macro-and micro-nutrients from the environment.Between the macro-nutrients,the inorganic nitrogen(e.g.,nitrate and ammonium)and amino acids are essential for plant survival and productivity.Beyond acting as macro-nutrients and structural components of macro-molecules,these nitrogen-containing molecules could also act as signaling molecules to orchestrate diverse genetic programs(Wang et al.,2018).

Sejima and Nishizawa have developed their work without explicitly referencing a theoretical discourse.However,they have stated that their housing projects describe their"architectural biography."This study presents the hypothesis that systermic theories had infu-enced their housing projects at a spatial and constructive Level.With the aim of testing it,the research produces four lines of results.Firstly,we observe that the word system is prominently current in a signifcant sample of their published texts.We describe how architects like Tomi-naga,Ito,Taki,and Shinohara,who infuenced Sejima when she was still a student,discussed this concept inspired by Christopher Alexander's texts.The second line brings together all the couple's single-family housing projects published between 1987 and 2010 for the first time in a single document,as well as an original graphic-constructive reconstruction of the most outstanding ones.Thirdly,we unveil the emergence of four constructive patterns by applying these theories to the graphic material developed.Finally,we summarize the results in dia-grams,showing the frequency,intensity,and continuity of the identified patterns in the four phases throughout the studied period.Verifying the hypothesis facilitates further research relate their domestic work and their other types of projects.

As for unmanned aircraft, the knowledge of the aircraft performance is directly related with the navigation, guidance, and control system programming. Therefore, the measured data in each phase of the flight must be sufficiently precise to obtain a good characterization of aircraft.This article proposes new methods of sending information to ground, which make it possible to know the aircraft behavior accurately, and for this purpose, four contributions have been made for ALO(Avión Ligero de Observación, Spanish acronym for Light Observation Aircraft). Currently, the characterization is based on data obtained at ten samples per second, insufficient to acquire detailed knowledge of what happened during the whole flight of an aircraft. As a result of these contributions, many more samples per second of accelerations and angular velocities are obtained at the most critical moments of the flight, such as takeoff or landing. Among the improvements included are data compression techniques, providing references to locate the measured data in time and identifying labels of each parameter.

Phosphorus(P)is an essential nutrient for plant growth and reproduction.Plants preferentially absorb P as orthophosphate(Pi),an ion that displays low solubility and that is readily fixed in the soil,making P limita-tion a condition common to many soils and Pi fertilization an inefficient practice.To cope with Pi limitation,plants have evolved a series of developmental and physiological responses,collectively known as the Pi starvation rescue system(PSR),aimed to improve Pi acquisition and use efficiency(PUE)and protect from Pi-starvation-induced stress.Intensive research has been carried out during the last 20 years to un-ravel the mechanisms underlying the control of the PSR in plants.Here we review the results of this research effort that have led to the identification and characterization of several core Pi starvation signaling components,including sensors,transcription factors,microRNAs(miRNAs)and miRNA inhibitors,kinases,phosphatases,and components of the proteostasis machinery.We also refer to recent results revealing the existence of intricate signaling interplays between Pi and other nutrients and antagonists,N,Fe,Zn,and As,that have changed the initial single-nutrient-centric view to a more integrated view of nutrient homeostasis.Finally,we discuss advances toward improving PUE and future research priorities.

Manipulation of parasite load induces significant changes in the structural-based throat color of male iberian green lizards

Current Zoology 2018年第3期64卷 293-302页

The honesty of structural-based ornaments is controversial. Sexual selection theory predicts that the honesty of a sexual signal relies on its cost of production or maintenance. Therefore, environmental factors with negative impact on individuals could generate high costs and affect the expression of these sexual signals. In this sense, parasites are a main cost for their hosts. To probe the effect of parasites on the structural-based coloration of a lacertid species , we have experimentally removed ticks from a group of male Iberian green lizards using an acaricide treatment (i.e., the broad-use insecticide fipronil). All individuals were radio-tracked and recaptured after 15 days to study changes in coloration in both the ultraviolet (UV)-blue (structural-based) and UV-yellow (structural and pigment-based) ornamentations after manipulation, as well as changes in endo- and ectoparasitic load and body condition. Additionally, after the experiment, we measured the skin inflammatory response to a mitogen. The fipronil treatment was effective in reducing ticks and it was associated with a significant reduction of hemoparasite load. Throughout the season, individuals treated with fipronil tended to maintain the brightness of the UV-blue throat coloration while control lizards tended to increase it. However, individuals treated with fipronil that were not infected with hemoparasites significantly reduced the brightness of the UV-blue throat coloration. Individuals with a higher initial tick load exhibited a lower UV saturation increment (UV-blue) and a higher brightness increment (UV-yellow) during the experiment. Overall these results experimentally support the idea that parasites adversely influence the expression of the structural-based coloration of male Iberian green lizards. This adds evidence to the hypothesis that sexual ornaments in lizards function as honest signals.

大型民用飞机的机翼设计用于承受从大气阵风到湍流到着陆冲击的各种载荷,机翼是需要进一步研究的重要结构.改进机翼设计的主要方法之一是分析晃动对承载液体的柔性机翼状结构动力学的阻尼效应.这将通过开发实验装置来实现,该装置将有助于建立和再现涉及物理领域的数值模型.因此,本工作的目的是使用数值方法光滑粒子流体动力学(SPH)作为主要数值工具,分析晃动在降低飞机结构设计载荷方面的影响.本研究中的一个关键因素是对比例实验的需求,这是评估计算工具是否能够准确近似不同比例的注册测量值的必要步骤.为此,建立了一个垂直振动水槽的数值模型,该模型是一个完全耦合的流固耦合问题.该结构通过质量-弹簧-阻尼器系统建模,对于内部流体,使用δ-SPH方法.特别是,研究了两个开放性问题:第一个问题是,当储罐的初始加速度是标准重力值的十倍时,重力对阻尼和能量耗散现象的影响程度;第二种问题旨在确认,当根据量纲分析对问题参数进行缩放时,SPH方程正确地再现了缩放定律.
