Characterization of the resistance of tomato accessions from the bgh-ufv to the geminivírus tomato yellow spot virus
The viruses transmitted by whiteflies are among those causing relevant losses in tomato cultivation. Among the measures to control these agents, introducing genes for resistance constitutes the main control measure, together with vector control. The objective of this work was to screen for sources of natural resistance to Tomato yellow spot virus (ToYSV) in S. lycopersicum germplasm from the Banco de Germoplasma de Hortaliças (BGH) of the Universidade Federal de Viçosa (UFV), Minas Gerais, Brazil. The 99 accessions and two susceptible controls were inoculated using biolistics. Inoculated plants were grown under greenhouse conditions. The percentage of plants displaying virus symptoms was evaluated at 10, 20 and 30 days after inoculation (DAI). Virus presence or absence in the inoculated plants was confirmed by hybridization with probes labeled with á-[32P]-dCTP, for each evaluation date. Inoculated plants produced typical disease symptoms showing different behavior on the genotypes in relation to ToYSV. Some of the evaluated genotypes showed higher virus tolerance compared to two susceptible controls, in particular the accessions BGH-2039V and BGH-2041 which showed no symptoms and no viral DNA accumulation in 80% of the inoculated plants at 30 DAI. The results suggest that the selected tomato accesses are good sources of resistance to new tomato cultivars tolerant to ToYSV.Os vírus transmitidos por moscas brancas estão entre aqueles que causam perdas relevantes na cultura do tomate. Entre as medidas para o controle desses agentes, a introdução de genes de resistência constitui a principal medida de controle, juntamente com o controle de vetores. O objetivo deste trabalho foi procurar fontes de resistência natural ao Tomato yellow spot virus (ToYSV) em germoplasma de S. lycopersicum do Banco de Germoplasma de Hortaliças (BGH) da Universidade Federal de Viçosa (UFV), Minas Gerais, Brasil. Noventa e nove subamostras e dois controles suscetíveis foram inoculados usando biobalística. As plantas inoculadas foram mantidas em casa de vegetação. A porcentagem de plantas exibindo sintomas do vírus foi avaliada aos 10, 20 e 30 dias após a inoculação (DAI). A presença ou ausência do vírus nas plantas inoculadas foi confirmada por hibridização com sondas marcadas com á-[32P]-dCTP, para cada data de avaliação. Plantas inoculadas produziram sintomas típicos da doença mostrando diferentes comportamentos dos genótipos em relação ao ToYSV. Alguns dos genótipos avaliados apresentaram maior tolerância ao vírus em relação aos dois controles suscetíveis, em particular as subamostras BGH-2039V e BGH-2041, que não apresentaram sintomas e no tinham acúmulo de DNA viral em 80% das plantas inoculadas aos 30 DAI. Os resultados sugerem que as subamostras de tomate selecionadas são boas fontes de resistência para novas cultivares de tomateiro tolerantes ao ToYSV

Low-Level Laser Application in the Early Myocardial Infarction Stage Has No Beneficial Role in Heart Failure
Low-level laser therapy (LLLT) has been targeted as a promising approach that can mitigate post infarction cardiac remodeling. There is some interesting evidence showing that the beneficial role of the LLLT could persist long-term even after the end of the application, but it remains to be systematically evaluated. Therefore, the present study aimed to test the hypothesis that LLLT beneficial effects in the early post-infarction cardiac remodeling could remain in overt heart failure even with the disruption of irradiations. Female Wistar rats were subjected to the coronary occlusion to induce myocardial infarction or Sham operation. A single LLLT application was carried out after 60 s and 3 days post-coronary occlusion, respectively. Echocardiography was performed 3 days and at the end of the experiment (5 weeks) to evaluate cardiac function. After the last echocardiographic examination. LV hemodynamic evaluation was performed at baseline and on sudden afterload increases. Compared with the Sham group, infarcted rats showed increased systolic and diastolic internal diameter as well as a depressed shortening fraction of LV. The only benefit of the LLLT was a higher shortening fraction after 3 days of infarction. However, treated-LLLT rats show a lower shortening fraction in the 5th week of study when compared with Sham and non-irradiated rats. A worsening of cardiac function was confirmed in the hemodynamic analysis as evidenced by the higher LV end-diastolic pressure and lower +dP/dt and dP/dt with five weeks of study. Cardiac functional reserve was also impaired by infarction as evidenced by an attenuated response of stroke work index and cardiac output to a sudden afterload stress, without LLLT repercussions. No significant differences were found in the myocardial expression of Akti NEGF pathway. Collectively, these findings illustrate that LLLT improves LV systolic function in the early post-infarction cardiac remodeling. However, this beneficial effect may be dependent on the maintenance of phototherapy. Long-term studies with LLLT application are needed to establish whether these effects ultimately translate into improved cardiac remodeling.Conselho Nacional de Desenvolvimento Cientifico e TecnologicoFAPESPNove de Julho Univ, Lab Biophoton, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Lab Cardiac Physiol, Sao Paulo, SP, BrazilNove de Julho Univ, Program Med, Sao Paulo, BrazilUniv Sao Judas Tadeu, Brazil Phys Educ & Aging Sci Program, Translat Physiol Lab, Sao Paulo, BrazilUniv Fed Sao Paulo, Lab Cardiac Physiol, Sao Paulo, SP, BrazilCNPq: 4400851/2014-8FAPESP: 09-54225/8FAPESP: 15/11028-9Web of Scienc
Building and revolutionising public healthcare: A living ecosystem to link and improve patient health data and outcomes in a Brazilian hospital
Objectives
To develop a Brazilian public hospital, Sao Paulo University Medical School Clinics Hospital, HCFMUSP, informational model to link and improve multiple patients' health data, care pathways and outcomes, to build a living real world ecosystem aiming to subsidize policy decision-making, support research and promote patients' engagement and involvement.
Methods
Policy-relevant linkage data including demography, diagnostics, outpatient and emergency room visits, hospitalizations, intensive care evolution, assisted mechanical ventilation or special equipment’s uses, electronic prescriptions, imaging and clinical laboratory tests results, surgery records, blood components use, and medical and multidisciplinary teams’ evolutions. Telemedicine-based hub developed for patient’s access to his own visits or procedures schedule, comprehensive data and results temporal series, and specific communications channels. Anonymized data sharing for Sao Paulo State Health Secretariat policy decision-making and SP Research Agency multicenter Data Lake for Covid-19 pandemic research. Stratified impact and economic analysis regarding clinical and co-morbid conditions research were published.
Results
Since March 2020, this informational model example comprises over 10,000 Covid-19 patient’s related data with more than 100,000 events registered. During the first pandemic trimester, upon SP Health Secretariat policy, the HCFMUSP Central Institute’s 900 ward and 300 ICU beds were the SP central reference for severe and critical admissions. In this first evaluation 88.4% had co-morbidities (e.g. 48.1% hypertension, 30.5% diabetes), 51.7% required ICU admission and 28.9% died. Average hospital length of stay was 10.7 days, mean cost per admission was US919.24. Age strata >69 years confirmed COVID-19, ICU, elevated C-reactive protein (inflammation) adjusted by D-dimer levels (thrombosis biomarker), higher mSOFA, mechanical ventilation, dialysis, surgery and comorbidities, remained significantly associated with higher (24%-200%) costs and poorer outcomes.
Conclusion
The informational model is proving to be beneficial for all stakeholders. Technology-based organized systems increased management accuracy and efficiency, emergency preparedness, facilitates patient’s involvement and participation, promote medical and multi-professionals teams’ knowledge development, and permits to subsidize policy decisions and to improve public health
Observation of Higgs boson production in association with a top quark pair at the LHC with the ATLAS detector
The observation of Higgs boson production in association with a top quark pair ( tt¯H ), based on the analysis of proton–proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider, is presented. Using data corresponding to integrated luminosities of up to 79.8 fb −1 , and considering Higgs boson decays into bb¯ , WW⁎ , τ+τ− , γγ , and ZZ⁎ , the observed significance is 5.8 standard deviations, compared to an expectation of 4.9 standard deviations. Combined with the tt¯H searches using a dataset corresponding to integrated luminosities of 4.5 fb −1 at 7 TeV and 20.3 fb −1 at 8 TeV, the observed (expected) significance is 6.3 (5.1) standard deviations. Assuming Standard Model branching fractions, the total tt¯H production cross section at 13 TeV is measured to be 670 ± 90 (stat.) −100+110 (syst.) fb, in agreement with the Standard Model prediction.Peer Reviewe
Measurement of photon–jet transverse momentum correlations in 5.02 TeV Pb + Pb and collisions with ATLAS
Jets created in association with a photon can be used as a calibrated probe to study energy loss in the medium created in nuclear collisions. Measurements of the transverse momentum balance between isolated photons and inclusive jets are presented using integrated luminosities of 0.49 nb of Pb+Pb collision data at TeV and 25 pb of collision data at TeV recorded with the ATLAS detector at the LHC. Photons with transverse momentum GeV and pseudorapidity . Distributions of the per-photon jet yield as a function of , , are corrected for detector effects via a two-dimensional unfolding procedure and reported at the particle level. In collisions, the distributions are well described by Monte Carlo event generators. In Pb+Pb collisions, the distribution is modified from that observed in collisions with increasing centrality, consistent with the picture of parton energy loss in the hot nuclear medium. The data are compared with a suite of energy-loss models and calculations.Peer Reviewe
Carbamazepine inhibits angiotensin I-converting enzyme, linking it to the pathogenesis of temporal lobe epilepsy
We find that a common mutation that increases angiotensin I-converting enzyme activity occurs with higher frequency in male patients suffering from refractory temporal lobe epilepsy. However, in their brains, the activity of the enzyme is downregulated. As an explanation, we surprisingly find that carbamazepine, commonly used to treat epilepsy, is an inhibitor of the enzyme, thus providing a direct link between epilepsy and the renin-angiotensin and kallikrein-kinin systems.
