4Cortisol Response in Breast Cancer:The Role of Physical Activity and Exercise显示文摘Chronic stress is a consistent sense of feeling pressured and overwhelmed for a long period of time and it has been defi ned as a maladaptive state that is associated with altered hypothalamic pituitary adrenal(HPA)axis.The hyperactivity of the HPA axis is commonly assessed by cortisol levels.Physical activity(PA)and exercise have been demonstrated to regulate cortisol patterns in different healthy study populations,but also in BC patients and survivors.The PA and exercise are related but have distinct concepts that are commonly misused.Nowadays,the regular practice of PA and exercise has been widely recognized as one main strategy to manage chronic stress and its related markers,like cortisol,remains elusive.In the present review,the authors focused on the evidence of the PA and exercise on cortisol patterns of BC patients and survivors.Margarida Marinho Sílvia Rocha-Rodrigues 2022Journal of Endocrinology Research2022,4,2:0
5An Updated Mini Review of Acute and Chronic Responses to Exercise Training-induced Irisin in Browning of White Fat显示文摘Nowadays,is well established that the benefits induced by exercise training(ET)affects not only skeletal muscle,but also other non-contractile organs over time.One potential mechanism underlying this crosstalk is the synthesis and secretion of several biological active factors,such as irisin,by muscle contractile activity.This hormone has been described to be able to induce a brown adipocyte-like phenotype in white adipose(WAT),increase whole-body metabolic rate,and therefore prevent and/or treat obesity-related metabolic diseases.Thus,the modulatory impact of ET on WAT may also occur through skeletal muscle-adipose organ axis.In this review,we summarize the acute and chronic adaptations to ET-induced irisin synthesis and secretion on the development of browning of white fat and,thus,providing an overview of the potential preventive and therapeutic role of ET on the obesity-related underlying pathways.Sílvia Rocha-Rodrigues Bruno Silva 2019Journal of Endocrinology Research2019,1,1:0
6Radiation and concomitant chemotherapy for patients with glioblastoma multiforme显示文摘Postoperative external beam radiotherapy was considered the standard adjuvant treatment for patients with glioblastoma multiforme until the advent of using the drug temozolomide(TMZ) in addition to radiotherapy. High-dose volume should be focal, minimizing whole brain irradiation. Modern imaging, using several magnetic resonance sequences, has improved the planning target volume definition. The total dose delivered should be in the range of 60 Gy in fraction sizes of 1.8-2.0 Gy. Currently, TMZ concomitant and adjuvant to radiotherapy has become the standard of care for glioblastoma multiforme patients. Radiotherapy dose-intensification and radiosensitizer approaches have not improved the outcome. In spite of the lack of high quality evidence, stereotactic radiotherapy can be considered for a selected group of patients. For elderly patients, data suggest that the same survival benefit can be achieved with similar morbidity using a shorter course of radiotherapy(hypofractionation). Elderly patients with tumors that exhibit methylation of the O-6-methylguanine-DNA methyltransferase promoter can benefit from TMZ alone.Salvador Villà Carme Balaà Sílvia Comas 2014Chinese Journal of Cancer2014,33,1:6

9Axonal growth inhibitors and their receptors in spinal cord injury:from biology to clinical translation显示文摘Axonal growth inhibitors are released during traumatic injuries to the adult mammalian central nervous system, including after spinal cord injury. These molecules accumulate at the injury site and form a highly inhibitory environment for axonal regeneration. Among these inhibitory molecules, myelinassociated inhibitors, including neurite outgrowth inhibitor A, oligodendrocyte myelin glycoprotein, myelin-associated glycoprotein, chondroitin sulfate proteoglycans and repulsive guidance molecule A are of particular importance. Due to their inhibitory nature, they represent exciting molecular targets to study axonal inhibition and regeneration after central injuries. These molecules are mainly produced by neurons, oligodendrocytes, and astrocytes within the scar and in its immediate vicinity. They exert their effects by binding to specific receptors, localized in the membranes of neurons. Receptors for these inhibitory cues include Nogo receptor 1, leucine-rich repeat, and Ig domain containing 1 and p75 neurotrophin receptor/tumor necrosis factor receptor superfamily member 19(that form a receptor complex that binds all myelin-associated inhibitors), and also paired immunoglobulin-like receptor B. Chondroitin sulfate proteoglycans and repulsive guidance molecule A bind to Nogo receptor 1, Nogo receptor 3, receptor protein tyrosine phosphatase σ and leucocyte common antigen related phosphatase, and neogenin, respectively. Once activated, these receptors initiate downstream signaling pathways, the most common amongst them being the Rho A/ROCK signaling pathway. These signaling cascades result in actin depolymerization, neurite outgrowth inhibition, and failure to regenerate after spinal cord injury. Currently, there are no approved pharmacological treatments to overcome spinal cord injuries other than physical rehabilitation and management of the array of symptoms brought on by spinal cord injuries. However, several novel therapies aiming to modulate these inhibitory proteins and/or their receptors are under investigation in ongoing clinical trials. Investigation has also been demonstrating that combinatorial therapies of growth inhibitors with other therapies, such as growth factors or stem-cell therapies, produce stronger results and their potential application in the clinics opens new venues in spinal cord injury treatment.Sílvia Sousa Chambel Célia Duarte Cruz 2023Neural Regeneration Research2023,18,12:1
10Explicit bivariate rate functions for large deviations in AR(1)and MA(1)processes with Gaussian innovations显示文摘We investigate the large deviations properties for centered stationary AR(1)and MA(1)processes with independent Gaussian innovations,by giving the explicit bivariate rate functions for the sequence of two-dimensional random vectors.Via the Contraction Principle,we provide the explicit rate functions for the sample mean and the sample second moment.In the AR(1)case,we also give the explicit rate function for the sequence of two-dimensional random vectors(W_(n))n≥2=(n^(-1(∑_(k=1)^(n)X_(k),∑_(k=1)^(n)X_(k)^(2))))_(n∈N)n≥2,but we obtain an analytic rate function that gives different values for the upper and lower bounds,depending on the evaluated set and its intersection with the respective set of exposed points.A careful analysis of the properties of a certain family of Toeplitz matrices is necessary.The large deviations properties of three particular sequences of one-dimensional random variables will follow after we show how to apply a weaker version of the Contraction Principle for our setting,providing new proofs for two already known results on the explicit deviation function for the sample second moment and Yule-Walker estimators.We exhibit the properties of the large deviations of the first-order empirical autocovariance,its explicit deviation function and this is also a new result.Maicon J.Karling Artur O.Lopes Sílvia R.C.Lopes 2023Probability, Uncertainty and Quantitative Risk2023,8,2:0
11Parameter estimation in Manneville–Pomeau processes显示文摘In this paper,we study a class of stochastic processes{X_(t)}t∈N,where X_(t)=φ■T_(s)^(t)(X_(0))is obtained from the iterations of the transformation T_(s),invariant for an ergodic probabilityμ_(s)on[0,1]and a certain constant by partial functionφ:[0,1]→R.We consider here the family of transformations T_(s):[0,1]→[0,1]indexed by a parameters>0,known as the Manneville–Pomeau family of transformations.The autocorrelation function of the resulting process decays hyperbolically(or polynomially)and we obtain efficient methods to estimate the parameter s from a finite time series.As a consequence,we also estimate the rate of convergence of the autocorrelation decay of these processes.We compare different estimation methods based on the periodogram function,the smoothed periodogram function,the variance of the partial sum,and the wavelet theory.To obtain our results we analyzed the properties of the spectral density function and the associated Fourier series.Barbara P.Olbermann Sílvia R.C.Lopes Artur O.Lopes 2023Probability, Uncertainty and Quantitative Risk2023,8,2:0
12Using meshes to change the characteristics of simulated rainfall produced by spray nozzles显示文摘Rainfall simulators have been used for many years contributing to the understanding of soil and water conservation processes.Nevertheless,rainfall simulators’design and operation might be rather demanding for achieving specific rainfall intensity distributions and drop characteristics and are still open for improvement.This study explores the potential of combining spray nozzle simulators with meshes to change rainfall characteristics,namely drop properties(drop diameters and fall speeds).A rainfall simulator laboratory set-up was prepared that enabled the incorporation of different wire meshes beneath the spray nozzles.The tests conducted in this exploratory work included different types of spray nozzles,mesh materials(plastic and steel),square apertures and wire thicknesses,and positions of the meshes in relation to the nozzles.Rainfall intensity and drop size distribution and fall speed were analysed.Results showed that the meshes combined with nozzles increased the mean rainfall intensity on the 1 m^(2) control plot below the nozzle and altered the rain drops’properties,by increasing the mass-weighted mean drop diameter,for example.Sílvia C.P.Carvalho João L.M.P.de Lima M.Isabel P.de Lima 2014International Soil and Water Conservation Research2014,2,2:0
