A PROMOÇÃO DE EMPRESAS DE PROJETO DE ARQUITETURA NA HOLANDA

Este artigo relata um projeto de pesquisa sobre as práticas de promoção dos arquitetos holandeses. Embora não seja difícil obter orientações de marketing para arquitetos, tem havido muito pouca pesquisa sobre as práticas de comercialização efetivamente empregadas. O que fica claro, e que muitas vezes é dito pela bibliografia, é que geralmente se acredita que os arquitetos não dedicam esforços suficientes para promover as suas atividades profissionais. Os pesquisadores partiram da hipótese de que é necessário estabelecer primeiro quais são as práticas reais dos arquitetos, antes de formular recomendações generalizadas para a profissão. A pesquisa foi baseada em três métodos: uma enquete com os membros do Instituto Real de Arquitetos holandeses (BNA); uma série de estudos de caso com empresas de projeto de arquitetura; e uma série de entrevistas - não só com arquitetos, mas também com clientes, com gestores de empreendimentos e com consultores de marketing. A intenção das entrevistas foi possibilitar uma comparação entre oferta e demanda no mercado. Por meio da pesquisa, apurou-se que a maioria dos arquitetos está trabalhando ativamente para promover uma imagem específica de suas empresas. Isso inclui tanto a promoção interna – informar seu próprio pessoal da imagem das empresas – quanto a promoção externa. 40% das empresas de arquitetura têm uma estratégia de longo prazo, 42% têm um plano de promoção, e 50% possuem algum conhecimento de como eles são percebidos pelo mercado. Esta é uma imagem melhor do que a situação que foi apresentada pelos consultores em suas entrevistas. Nenhum padrão claro de co-relação foi identificado entre prática de promoção e tipo de empresa, com a ressalva de que as grandes empresas foram mais ativas na promoção do que empresas menores, e estranhamente, que as empresas que operam no setor público eram mais ativas, apesar do fato de o setor público na Europa contratar através de concurso. Entrevistas com os contratantes mostraram que os clientes individuais seguem estratégias para seleção de arquitetos diferentes do que fazem clientes empresariais ou gestores de projeto. No entanto, a reputação e familiaridade com o nome desempenham um papel importante em ambas as áreas. Os resultados, no mínimo, derrubam a afirmação muito comum de que os arquitetos holandeses não se promovem ativamente. O que resta a ser determinado é quais seriam as práticas de promoção mais bem sucedidas.Proposal: This paper reports on a project to survey the promotion practices of Dutch architects. Although it is not difficult to find marketing advice for architects there has been very little research into the actual marketing practices employed. What is clear, and is often repeated in the literature, is that it is generally assumed that architects do not devote adequate energies to promoting their practices. The researchers felt that it is necessary to first establish the actual practices of architects before formulating generalized advice for the profession. The research was based on three empirical methods: a survey of the members of the Royal Institute of Dutch Architects (BNA), a series of case studies of architectural firms, and a series of interviews – not only of architects but also of clients, project managers, and marketing consultants. The intention of the interviews was to make possible a comparison between the supply and demand sides of the market. Through the survey it was established that the majority of architects are actively working to promote a specific image of their offices. This includes both internal promotion – informing the staff of the firms image – and external promotion. 40% of architectural firms have a long term strategy, 42% a promotion plan, and 50% have some knowledge of how they are perceived in the market. This is a better picture of the situation than was given by the consultants in their interviews. No clear pattern of relationships emerged between promotion practice and type of firm, with the exception that larger firms were more active in promotion than smaller firms, and strangely, that firms active in the public sector were more active (this despite the fact that public sector work is obtained through the European Tendering procedure). Interviews of clients showed that the individual clients follow different strategies in selecting architects than do professional clients or project managers. However, reputation and name familiarity play a large role in both areas. The findings lay to rest the common assertion that Dutch architects, at least, to not actively promote their practices. What remains to determine is which practices are more successful

An Ecophisiological Proposal to Manage Natural Grasslands: A Long Term Trial

Natural grasslands on Southern Brazil comprise the so called “Rio de La Plata Grasslands” in South America. They are an important fodder source for ruminant pastoral systems and contribute to regional ecosystem services. Strength of these grasslands is its floristic diversity that poses a dilemma to farmers: how to choose management protocols that could be applied for hundreds of species. We propose to use a functional ecophysiological approach based on groups of grasses, the most abundant on aerial biomass of this natural grasslands. We clustered the most frequent grasses in two groups based on its leaf traits (leaf dry matter content and specific leaf area). These traits are functional clues to growth rhythms and nutritive value that could separate grasses in “resource capture” and “resource conservation” groups, both important for forage production and ecosystem services. Evaluating the most frequent grasses in each group we found they have an average of 375 degree-days, for “resource capture” and 750 degree-day for “resource conservation” groups, as its leaf elongation duration. So we evaluated a rotational grazing system based on this morphogenic trait for beef heifers rearing on natural grasslands from 2010 to 2019. We chose these experimental animals, as a model by its nutrient requirements and relevance for regional rearing and breeding systems. Our results indicate an average daily gain that is adequate to reach mating age and weight targets (0,3 kg/heifer/day to mate at 24 months) and allowed a higher stocking rate and gain per area when compared to regional standards (1,100 kg of live weight/ha and 370 kg/ha versus 600 and 70 kg/ha). All this animal performance was obtained without changing floristic diversity and also enhancing ecosystem services as CO2 sequestration. We concluded that this approach could allow farmers to conciliate the dilemma of production and conservation in pastoral ecosystems

Levels of plasma homocysteine in pseudoexfoliation glaucoma.

BACKGROUND: To examine levels of serum homocysteine (Hcy), vitamin B12 and folic acid in patients with pseudoexfoliation glaucoma (PEXG), primary open-angle glaucoma (POAG), and healthy control subjects. METHODS: This study included 36 patients with PEXG, 40 with POAG, and 40 age-matched healthy subjects. Fasting plasma Hcy concentrations and levels of serum vitamin B12 and folic acid were measured using competitive chemiluminescent enzyme immunoassay; values exceeding 14 μm/l were considered elevated. RESULTS: Mean plasma Hcy was significantly higher in PEXG (16.55 ± 7.23 μm/l) compared with POAG (13.91 ± 3.61 μm/l) and controls (13.12 ± 5.13 μm/l) (p = 0.03 and p = 0.0007 respectively). There were no statistical differences in serum vitamin B12 and folic acid levels among PEXG, POAG and control subjects (p > 0.05). A moderate, although statistically significant, relationship between Hcy and folic acid levels was found in the PEXG group (R(2) = 0.23, p = 0.003). Hcy levels were found not to be related with folic acid or vitamin B12 in either POAG or control subjects. CONCLUSIONS: In this study, plasma Hcy is significantly higher in PEXG group than the POAG and control groups. Hyper-Hcy might play a role in the pathogenesis of PEXG. Hyper-Hcy may be an independent factor stressing vasculopathy in addition to pseudoexfoliation, so might be a modifiable risk factor for PEXG

Patient-Reported Outcomes After Platelet-Rich Plasma, Bone Marrow Aspirate, and Adipose-Derived Mesenchymal Stem Cell Injections for Symptomatic Knee Osteoarthritis

Objective: The objective of this study was to compare platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC), and adipose-derived mesenchymal stem cell (MSC) injections in the treatment of osteoarthritis (OA) of the knee using functional scores. Methods: A total of 89 patients with painful knee OA were included in this study. Patients were assigned to one of the 3 treatments according to severity of OA as indicated by symptoms and radiography to PRP (stage I), BMAC (stage II), or adipose-derived MSC (stage III). Clinical assessment was performed using the Knee Society Score, which combines the Knee Score, based on the clinical parameters, and the Functional Score, and IKDC score. Surveys were completed at preoperative and at 90, 180, and 265 days postoperative. The follow-up responses were compared with baseline and between treatment groups. Results: Treatment with PRP, BMAC, and adipose-derived MSC included 29 (32.6%), 27 (30.3%), and 33 (37.1%) patients, respectively. For the total group, median age was 61 years (range: 22-84 years). Score values were comparable among treatment groups at baseline. Statistically significant improvement was observed in the 3 groups according to the 3 scores at all time points during follow-up compared with baseline. No difference was found among treatment type. Conclusions: Our findings support previous reports and encourage further research on the use of these cost-effective treatments for OA of the knee.Fil: Estrada, Esteban.

Critical role of mTOR, PPARγ and PPARδ signaling in regulating early pregnancy decidual function, embryo viability and feto-placental growth

STUDY QUESTION: What are the consequences of inhibiting mTOR, the mechanistic target of rapamycin (mTOR), and the peroxisome proliferator activated receptor gamma (PPARγ) and PPARδ pathways in the early post-implantation period on decidual function, embryo viability and feto-placental growth in the ratγ SUMMARY ANSWER: mTOR inhibition from Days 7 to 9 of pregnancy in rats caused decidual PPARγ and PPARδ upregulation on Day 9 of pregnancy and resulted in embryo resorption by Day 14 of pregnancy. PPARγ and PPARδ inhibition differentially affected decidual mTOR signaling and levels of target proteins relevant to lipid histotrophic nutrition and led to reduced feto-placental weights on Day 14 of pregnancy. WHAT IS KNOWN ALREADY: Although mTOR, PPARγ and PPARδ are nutrient sensors important during implantation, the role of these signaling pathways in decidual function and how they interact in the early post-implantation period are unknown. Perilipin 2 (PLIN2) and fatty acid binding protein 4 (FABP4), two adipogenic proteins involved in lipid histotrophic nutrition, are targets of mTOR and PPAR signaling pathways in a variety of tissues. STUDY DESIGN, SIZE, DURATION: Rapamycin (mTOR inhibitor, 0.75 mg/kg, sc), T0070907 (PPARγ inhibitor, 0.001 mg/kg, sc), GSK0660 (PPARδ inhibitor, 0.1 mg/kg, sc) or vehicle was injected daily to pregnant rats from Days 7 to 9 of pregnancy and the studies were performed on Day 9 of pregnancy (n = 7 per group) or Day 14 of pregnancy (n = 7 per group). PARTICIPANTS/MATERIALS, SETTING, METHODS: On Day 9 of pregnancy, rat decidua were collected and prepared for western blot and immunohistochemical studies. On Day 14 of pregnancy, the resorption rate, number of viable fetuses, crown-rump length and placental and decidual weights were determined. MAIN RESULTS AND THE ROLE OF CHANCE: Inhibition of mTOR in the early post-implantation period led to a reduction in FABP4 protein levels, an increase in PLIN2 levels and an upregulation of PPARγ and PPARδ in 9-day-pregnant rat decidua. Most embryos were viable on Day 9 of pregnancy but had resorbed by Day 14 of pregnancy. This denotes a key function of mTOR in the post-implantation period and suggests that activation of PPAR signaling was insufficient to compensate for impaired nutritional/survival signaling induced by mTOR inhibition. Inhibition of PPARγ signaling resulted in decreased decidual PLIN2 and FABP4 protein expression as well as in inhibition of decidual mTOR signaling in Day 9 of pregnancy. This treatment also reduced feto-placental growth on Day 14 of pregnancy, revealing the relevance of PPARγ signaling in sustaining post-implantation growth. Moreover, following inhibition of PPARδ, PLIN2 levels were decreased and mTOR complex 1 and 2 signaling was altered in decidua on Day 9 of pregnancy. On Day 14 of pregnancy, PPARδ inhibition caused reduced fetoplacental weight, increased decidual weight and increased resorption rate, suggesting a key role of PPARδ in sustaining post-implantation development. LARGE SCALE DATA: Not applicable. LIMITATIONS, REASONS FOR CAUTION: This is an in vivo animal study and the relevance of the results for humans remains to be established. WIDER IMPLICATIONS OF THE FINDINGS: The early post-implantation period is a critical window of development and changes in the intrauterine environment may cause embryo resorption and lead to placental and fetal growth restriction. mTOR, PPARγ and PPARδ signaling are decidual nutrient sensors with extensive cross-talk that regulates adipogenic proteins involved in histotrophic nutrition and important for embryo viability and early placental and fetal development and growth.

Hyperpigmented spots at fundus examination: a new ocular sign in neurofibromatosis type I

Background: Neurofibromatosis Type I (NF1), also termed von Recklinghausen disease, is a rare genetic disorder that is transmitted by autosomal dominant inheritance, with complete penetrance and variable expressivity. It is caused by mutation in the NF1 gene on chromosome 17 encoding for neurofibromin, a protein with oncosuppressive activity, and it is 50% sporadic or inherited. The disease is characterized by a broad spectrum of clinical manifestations, mainly involving the nervous system, the eye and skin, and a predisposition to develop multiple benign and malignant neoplasms. Ocular diagnostic hallmarks of NF1 include optic gliomas, iris Lisch nodules, orbital and eyelid neurofibromas, eyelid café-au-lait spots. Choroidal nodules and microvascular abnormalities have recently been identified as additional NF1-related ocular manifestations. The present study was designed to describe the features and clinical significance of a new sign related to the visual apparatus in NF-1, represented by hyperpigmented spots (HSs) of the fundus oculi. Results: HSs were detected in 60 (24.1%) out of 249 patients with NF1, with a positive predictive value of 100% and a negative predictive value of 44.2%. None of the healthy subjects (150 subjects) showed the presence of HSs. HSs were visible under indirect ophthalmoscopy, ultra-wide field (UWF) pseudocolor imaging and red-only laser image, near-infrared reflectance (NIR)-OCT, but they were not appreciable on UWF green reflectance. The location and features of pigmentary lesions matched with the already studied NF1-related choroidal nodules. No significant difference was found between the group of patients (n = 60) with ocular HSs and the group of patients (n = 189) without ocular pigmented spots in terms of age, gender or severity grading of the disease. A statistically significant association was demonstrated between the presence of HSs and neurofibromas (p = 0.047), and between the presence of HSs and NF1-related retinal microvascular abnormalities (p = 0.017). Conclusions: We described a new ocular sign represented by HSs of the fundus in NF1. The presence of HSs was not a negative prognostic factor of the disease. Following multimodal imaging, we demonstrated that HSs and choroidal nodules were consistent with the same type of lesion, and simple indirect ophthalmoscopy allowed for screening of HSs in NF1
