Abstract:
ABSTRACT Serum amyloid A (SAA), a plasma protein inducible in response to many inflammatory conditions, is associated with the pathogenesis of several diseases including reactive amyloidosis, rheumatoid arthritis, and atherosclerosis. We have previously reported an element of the SAA promoter, designated SAA-activating sequence (SAS), that is involved in the inflammation-induced SAA expression, and a nuclear factor, SAS-binding factor (SAF), that interacts with the SAS element has been identified previously (A. Ray and B. K. Ray, Mol. Cell. Biol. 16:1584–1594, 1996). To evaluate how SAF is involved in SAA promoter activation, we have investigated structural features and functional characteristics of this transcription factor. Our studies indicate that SAF belongs to a family of transcription factors characterized by the presence of multiple zinc finger motifs of the Cys2-His2 type at the carboxyl end. Of the three cloned SAF cDNAs (SAF-1, SAF-5, and SAF-8), SAF-1 isoform showed a high degree of homology to MAZ/ZF87/Pur-1 protein while SAF-5 and SAF-8 isoforms are unique and are related to SAF-1/MAZ/ZF87/Pur-1 at the zinc finger domains but different elsewhere. Although structurally distinct, all members are capable of activating SAS element-mediated expression and display virtually identical sequence specificities. However, varying levels of expression of members of this gene family were observed in different tissues. Functional activity of SAF is regulated by a posttranslational event as SAF DNA-binding and transactivation abilities are increased by a protein phosphatase inhibitor, okadaic acid, and inhibited by a protein kinase inhibitor, H7. Consistent with this observation, increased DNA binding of the cloned SAF and its hyperphosphorylation, in response to okadaic acid treatment of the transfected cells, were observed. Taken together, our results suggest that, in addition to tissue-specific expression, SAFs, a family of zinc finger transcription factors, undergo a modification by a posttranslational event that confers their SAA promoter-binding activity and transactivation potential.

Abstract:
Com o objetivo de avaliar características morfológicas dos cafeeiros e a conservação de umidade do solo em diferentes sistemas agroflorestais, foi realizado este experimento. O ensaio foi conduzido no município de Barra do Choça-BA, em uma propriedade particular, sendo observadas três áreas de produção distintas: (1) cafeeiro cultivado a pleno sol (MONO), (2) cafeeiro conduzido em associação com o vinhático (SAF-CV) e (3) cafeeiro associado ao abacateiro e ingazeiro (SAF-CAI). Em março/2007, época úmida, e em agosto/2007, época com menor precipitação, foram realizadas avaliações relacionadas à incidência de luz (determinação do nível de sombreamento dos sistemas com base no percentual de radiação fotossintética incidente em relação à radiação fotossintética global), à umidade do solo (US) e à morfologia do cafeeiro (área foliar individual (AFI), altura e diâmetro do caule e da copa). Foi verificado intenso sombreamento para os SAFs (março, 93,3% em SAF-CV e 82,3% em SAF-CAI; e agosto, 37,5% em SAF-CV e 89,5% em SAF-CAI). Na época de menor precipitação, maior US foi observada para MONO (17,3%), seguido por SAFCV (15,1%) e SAF-CAI (9,5%). Os sistemas de cultivo definiram os parâmetros morfológicos avaliados do cafeeiro, sendo observada maior AFI para os SAFs nas duas avaliações realizadas.

Abstract:
No Vale do Paraíba do Sul, entre os estados do Rio de Janeiro e São Paulo, a substituição da Mata Atlântica para o cultivo do café degradou os solos e os cursos d’água. O cultivo de espécies florestais pode ajudar a restaurar esse ambiente. O guanandi (Calophyllum brasiliense Cambess.) é uma espécie florestal nativa com grande potencial de exploração econômica da madeira. O seu cultivo em sistema agroflorestal – SAF pode tornar-se mais vantajoso devido o seu moderado crescimento. Os objetivos com essa pesquisa foram comparar o crescimento do guanandi em monocultura e na diversificação agroflorestal em SAFs simples e biodiverso, assim como avaliar o desempenho da mandioca (Manihot esculenta Crantz.) e araruta (Maranta arundinacea L.) nesses sistemas, em ciclos com alta precipitação pluvial e escassez hídrica. O SAF biodiverso foi acrescido de feijão guandu, bananeira, palmeira juçara e diversidade arbórea. Os sistemas agroflorestais não prejudicaram o crescimento do guanandi, que incrementou a circunferência a altura do peito no SAF simples após três anos de conversão. As culturas alimentares de mandioca e araruta apresentaram desempenho compatível com a densidade de plantio utilizada nos SAFs, com produções significativamente superiores no SAF simples. A araruta suportou o estresse ambiental em ambos SAFs e dispensa o replantio, ocupando naturalmente o sub-bosque. O SAF simples é um sistema para agricultores interessados em obter o máximo rendimento de cultivos anuais em associação com a espécie florestal. O SAF biodiverso é adequado para diversificar a produção agrícola e restaurar o ambiente concomitantemente.

Abstract:
Abstract. The analysis of data describing damage caused by mass movements in Calabria (Italy) allowed the organisation of the Support Analysis Framework (SAF), a spreadsheet that converts damage descriptions into numerical indices expressing direct, indirect, and intangible damage. The SAF assesses damage indices of past mass movements and the potential outcomes of dormant phenomena re-activations. It is based on the effects on damaged elements and is independent of both physical and geometric phenomenon characteristics. SAF sections that assess direct damage encompass several lines, each describing an element characterised by a value fixed on a relative arbitrary scale. The levels of loss are classified as: L4: complete; L3: high; L2: medium; or L1: low. For a generic line l, the SAF multiplies the value of a damaged element by its level of loss, obtaining dl, the contribution of the line to the damage. Indirect damage is appraised by two sections accounting for: (a) actions aiming to overcome emergency situations and (b) actions aiming to restore pre-movement conditions. The level of loss depends on the number of people involved (a) or the cost of actions (b). For intangible damage, the level of loss depends on the number of people involved. We examined three phenomena, assessing damage using the SAF and SAFL, customised versions of SAF based on the elements actually present in the analysed municipalities that consider the values of elements in the community framework. We show that in less populated, inland, and affluent municipalities, the impact of mass movements is greater than in coastal areas. The SAF can be useful to sort groups of phenomena according to their probable future damage, supplying results significant either for insurance companies or for local authorities involved in both disaster management and planning of defensive measures.

Abstract:
Resumo A síndrome antifosfolipíde (SAF) é uma doença autoimune sistêmica caracterizada por trombose arterial ou venosa recorrente e/ou morbidade gestacional e pela presença dos anticorpos antifosfolipídeos, podendo apresentar outras manifestações vasculares, como microangiopatia, arteriopatia crônica e SAF catastrófica. Determinados testes laboratoriais para a síndrome (por exemplo, o anticoagulante lúpico) podem sofrer interferência do uso de medicações anticoagulantes, dificultando o diagnóstico. A fisiopatologia da SAF é complexa, sendo enumerados no texto diversos mecanismos patogênicos relacionados à coagulação, ao endotélio e às plaquetas. Por fim, discutimos o tratamento da SAF de acordo com a presença e o tipo de manifestações clínicas, o uso dos anticoagulantes orais diretos e o manejo perioperatório de pacientes com SAF.

Abstract:
Los sistemas agroforestales (SAF) combinan de manera simultánea o secuencial los árboles maderables y las plantas de cultivos alimenticios, ofreciendo soluciones para los problemas productivos y el uso sostenible de la tierra en las zonas rurales. El objetivo del estudio fue cuantificar la cantidad de carbono en el suelo y la biomasa aérea de tres sistemas agroforestales durante el primer año de instalación. En los SAF se usaron combinaciones de una especie forestal maderable (Guazuma crinita) con tres especies de uso comestible o forrajero: Inga edulis, Theobroma cacao y Cajanus cajan (SAF ), Schizolobium amazonicum, 1 Theobroma cacao y Cajanus cajan (SAF2 ), y Leucaena leucocephala, Theobroma cacao y Cajanus cajan (SAF ). En cada SAF de 55 m x 85 m, se establecieron cuatro transectos de 4 m x 25 m para determinar la 3 biomasa aérea arbórea, cuatro subparcelas de 1 m x 1 m para determinar la biomasa arbustiva y herbácea, y cuatro subparcelas de 50 cm x 50 cm para evaluar la necromasa (hojarasca), y cuatro calicatas donde tomamos muestras del suelo a 0-10 y 10-20 cm de profundidad para determinar el contenido de carbono en el suelo. Los resultados muestran una acumulación de carbono durante el primer año en la biomasa y necromasa aérea de -1 -1 -1 -1 9.44 t.C ha en SAF , 11.40 t.C ha en SAF y 11.37 t.C ha en SAF ; y en el suelo de 23.98 t.C ha en SAF , 1 2 3 1 -1 -1 25,39 t.C ha en SAF y 25,83 t.C ha en SAF . El carbono orgánico en el suelo representa casi el 60% del 2 3 carbono total almacenado en estos sistemas agroforestales y es notable resaltar que incrementa durante el primer año de la plantación. Estos resultados son la línea base de nuevos estudios de captura de carbono en sistemas agroforestales.

Abstract:
Background Patients with myeloproliferative neoplasms (MPNs) are faced with severe disease-related fatigue among a range of other constitutional and spleen-related symptoms. The MPN-Symptom Assessment Form (SAF) is recommended for use to characterize symptom burden (Scherber R, et al. Blood 2011). Within the SAF, a profile of 18 symptom items are evaluated ranging in severity from 0 (absent) to 10 (worst imaginable). The SAF is often summarized to the MPN-SAF Total Symptom Score (TSS) for analysis purposes - a single computed sum of the 10 most clinically meaningful symptom scores, including fatigue (Emanuel R, et al. J Clin Oncol 2012). Though the SAF includes a fatigue item, initial deployments of the MPN-SAF TSS incorporated a 0-10 scaled fatigue item taken from the Brief Fatigue Inventory (BFI; Mendoza T, et al. Cancer 1999). A subsequent version of the MPN-SAF TSS for use within myelofibrosis clinical trials (called the MFSAF v4; Gwaltney C, et al. Leuk Res 2017) employed a harmonized fatigue item. This analysis employing data from two studies was carried out to assess the use of the SAF fatigue item within the MPN-SAF TSS for consistency with the MFSAF v4. Methods Both BFI and SAF fatigue items were included in an initial online survey evaluating disease burden among patients with MPNs. Participants were assigned to survey variants as a function of their age. Survey variants included those to receive 1 instance of either the BFI or SAF fatigue item, instances of both BFI and SAF, or 2 instances of the same fatigue item. Surveying was aimed to assess the worst symptom experience in the patient's last 24 hours. Additionally, an independent survey assessing the impact of COVID-19 among MPN patients was deployed using the SAF fatigue item for the MPN-SAF TSS. This modified version was then used to test internal validity. Pearson correlation (r) and t-tests were used to assess association, Bland-Altman methods were used to evaluate systematic agreement between BFI and SAF fatigue scores, and Cronbach's alpha was used to measure internal consistency. Results There were 229 participants assigned both BFI and SAF fatigue items within the same survey. Among them, 51% (n=117) received the BFI item first and 49% (n=112) the SAF item first. No difference was seen between first and second fatigue scores (mean difference [first-second] = 0.00; 95%CI -0.18, 0.17). BFI and SAF fatigue scores were highly correlated (r=0.88, p<0.001) and showed 88.7% agreement in categorizing severe versus non-severe fatigue (score ≥ 7 versus < 7). Overall concordance in severity category was 73.4% (category [score range]: absent [0]; mild [1-3]; moderate [4-6]; severe [7-10]). Constructing the MPN-SAF TSS using the BFI and SAF fatigue components separately, the original and modified MPN-SAF TSS were nearly identical (r=0.997, p<0.001), and had equivalent internal consistency (both Cronbach's alpha=0.88). The Bland-Altman plot further indicates the 2 fatigue measures have high agreement with no evidence of directional bias and negligible overall bias (Figure 1: regression slope = -0.04, p=0.25; mean difference=0.22; 95%CI 0.05, 0.39). Within the COVID-19 survey (n=1217), the modified version of the MPN-SAF TSS was consistent with known correlates among disease characteristics (Emanuel R, et al. J Clin Oncol 2012). For example, more severe MPN-SAF TSS scores were highly correlated with low quality-of-life (n=1156, r = -0.50, p<0.001), and associated with those reporting spleen enlargement (n=301) versus not (n=617) (p<0.001; mean difference=7.7; 95%CI 5.4, 10.1). Conclusion The BFI and SAF fatigue items are highly consistent in raw score, severity category, and in contribution to the MPN-SAF TSS. There was no order effect seen in which fatigue item was asked first. The independent COVID-19 survey using the modified MPN-SAF TSS was validated and shows high internal consistent. In the ongoing development to capture the symptom experience, this analysis shows disease-related fatigue is equivalently measured using the SAF fatigue survey item in harmonization with the MFSAF v4.

Abstract:
Serum amyloid A (SAA) is a plasma protein which has been associated with several diseases, including amyloidosis, arthritis, and atherosclerosis, and its abnormal expression, particularly in nonhepatic cells, is implicated in the pathogenesis of these diseases. Transfection and DNA-binding studies were performed to investigate the mechanism controlling cytokine-induced, nonhepatic expression of the SAA gene. We have identified a novel promoter, located between positions -280 and 224, that confers interleukin-6 (IL-6) inducibility to an SAA-chloramphenicol acetyltransferase reporter gene in both nonhepatic and hepatic cells. DNase I protection assays revealed, within this region, three homologous highly pyrimidine rich octanucleotide sequence motifs, termed SAA-activating sequences (SAS). Specific mutations within these three SAS motifs severely reduced IL-6-mediated induction of the reporter gene in transfected nonhepatic cells but not in liver cells. A nuclear factor activated by IL-6 in both hepatic and nonhepatic cells efficiently interacts with the SAS. The induction kinetics and cycloheximide sensitivity of this SAS-binding factor (SAF) suggested that de novo synthesis of this factor itself or an activator protein is essential. Loss of DNA-binding ability as a result of in vitro dephosphorylation, induction of SAA-chloramphenicol acetyltransferase reporter gene activity in the presence of genistein, a protein kinase inhibitor, further indicate that a phosphorylation step is necessary for the activation of SAF. Our results suggest that SAF is a key regulator of cytokine-mediated SAA gene expression in some nonhepatic cells.

Abstract:
Des connexions entre la réponse aux dommages à l'ADN et le métabolisme de l'ARN ont récemment été mises en évidence. Mon équipe a identifié une protéine de liaison à l'ARN, SAF-A/hnRNP U, comme un substrat de la DNA-PK, kinase clé de la réparation des cassures double-brin de l'ADN. J'ai étudié l'implication de SAF-A dans la réponse aux dommages de l'ADN. Après micro-irradiation laser, SAF-A-GFP est recrutée transitoirement sur le site de dommage avant d'en être exclue. Ces deux phases sont indépendantes. Le recrutement de SAF-A dépend de PARP, tandis que son exclusion dépend d'ATM, d'ATR et de la DNA-PK. Le domaine de liaison à l'ARN de SAF-A reproduit la dynamique de SAF-A. Ce domaine interagit majoritairement avec des protéines de liaison à l'ARN, dont FUS et TAF15, qui présentent une dynamique similaire. L'inhibition de la transcription abolit la phase d'exclusion de SAF-A, suggérant que l'exclusion concerne la fraction de SAF-A engagée dans la transcription. Des conditions anormales de transcription conduisent à la formation d'hybrides ARN:ADN (R-loop). Pour les détecter, nous avons construit une lignée cellulaire exprimant une RNAseHI fusionnée à la mCherry et inactive (RmC), mais qui peut se lier aux R-loops. Après micro-irradiation laser, la RmC est recrutée sur l'ADN endommagé. Lorsque l'exclusion de SAF-A est bloquée, le recrutement de la RmC est prolongé. La surexpression de la RNAseHI mutée compromet la survie cellulaire après irradiation aux rayons X. Ces résultats mettent en évidence l'exclusion des protéines de liaison à l'ARN comme la conséquence d'un mécanisme de résolution des R-loops se formant suite aux dommages de l'ADN dans les régions transcrites
An expanding aspect of the DNA Damage Response (DDR) is its connexion with RNA metabolism. My team has identified the RNA-binding protein SAF-A/hnRNP U as a substrate for DNA-PK, the key kinase in DNA double-strand breaks repair. I have investigated SAF-A involvement in the DDR. After laser microirradiation, SAF-A-GFP dynamics exhibited a two phases profile with a first transient recruitment in the damaged nuclear area followed by a prolonged exclusion. The two phases were uncoupled. SAF-A recruitment was PARP-dependent, while its exclusion relied on ATM, ATR and DNA-PK. SAF-A RNA-binding domain recapitulated SAF-A dynamics after DNA damage. Mass-spectrometry analysis using this domain as a bait identified mostly RNA-binding partners, at least two of them (FUS and TAF15) exhibited similar dynamics. Upon transcription inhibition, SAF-A exclusion was abolished, supporting that it concerns the pool of SAF-A engaged in RNA metabolism. Given that abnormal transcription conditions have been shown to promote RNA:DNA hybrids formation (R-loop), we constructed a cell line expressing a catalytically inactive mCherry-tagged RNAseHI (RmC), which retains its ability to bind R-loop. RmC recruitment to the laser damage site was abolished upon transcription inhibition. When SAF-A exclusion was blocked, RmC exhibited a prolonged recruitment, supporting that SAF-A release is a readout of R-loops resolution post-DNA damage. Finally, overexpressing this mutated RNAseHI negatively impacted cell survival after X-ray irradiation. These results uncover an anti-R-loop mechanism at DNA damage sites in transcribed areas testified by the post-damage exclusion of RNA-binding proteins from these sites

O potencial de pite aumenta com o percentual de ferrita, enquanto a dureza é pouco influenciada pela energia de soldagem

Abstract:
XIST RNA established the precedent for a noncoding RNA that stably associates with and regulates chromatin, however it remains poorly understood how such RNAs structurally associate with the interphase chromosome territory. I demonstrate that transgenic XIST RNA localizes in cis to an autosome as it does to the inactive X chromosome, hence the RNA recognizes a structure common to all chromosomes. I reassess the prevalent thinking in the field that a single protein, Scaffold Attachment Factor-A (SAF-A/hnRNP U), provides a single molecule bridge required to directly tether the RNA to DNA. In an extensive series of experiments in multiple cell types, I examine the effects of SAF-A depletion or different SAF-A mutations on XIST RNA localization, and I force XIST RNA retention at mitosis to examine the effect on SAF-A. I find that SAF-A is not required to localize XIST RNA but is one of multiple proteins involved, some of which frequently become lost or compromised in cancer. I additionally examine SAF-A’s potential role localizing repeat-rich CoT-1 RNA, a class of abundant RNAs that we show tightly and stably localize to euchromatic interphase chromosome territories, but release upon disruption of the nuclear scaffold. Overall, findings suggest that instead of “tethering” chromosomal RNAs to the scaffold, SAF-A is one component of a multi-component matrix/scaffold supporting interphase nuclear architecture. Results indicate that Cot-1 and XIST RNAs form integral components of this scaffold and are required to maintain the chromosomal association of SAF-A, substantially advancing understanding of how chromatin-associated RNAs contribute to nuclear structure.

The great demand for techniques that can detect and determine the degree of susceptibility to corrosion motivated thedevelopment of a research project that resulted in the construction of a portable electrochemical cell that has been validated according to ASTM A262. The success of this technique for nondestructive evaluation has motivated the expansion of this technique to other materials and phenomena of precipitation. In this work it was evaluated the use of this EPR-DL portable cell used applied for assessing the susceptibility to corrosion in super duplex stainless steels UNSS32750 and UNSS32760.Those materials were heat treated at 475ÂC and 850ÂC at different time of creating different patterns precipitation of deleterious phases to be detected by the cell. The solutions used were: 2M H2SO4 +0.01 M KSCN +0.5 M NaCl (solution 1 ) and 2M H2SO4 +0.01 M KSCN +1.0 M NaCl (solution 2) and the speedsscanswerestudied: 1.67 mV / s , 3.0 mV / s and 6.0 mV / s. To prove the presence of deleterious phases precipitation and associate them with the electrochemical behavior presentedby the electrochemical cell, the sampleshad theirmicrostructuresanalyzedby optical microscopy (OM), scanning electron microscopy (SEM), and energy dispersive of X-ray spectroscopy (EDS). Also the consumption of ferrite magnetic phase was assessed with ferrite scope and performed Vickers hardness tests to analyze the increasing in hardness due to precipitation of deleterious phases. It was observed by OM, SEM / EDS, ferrite scope, EPR- DL and Vickers hardness, that as much longer the heat treatment the amount of deleterious phasesprecipitated was increased. The results demonstrated that the solution 2 was the most effective in detecting susceptibility to corrosion, being capable to detect the depletion of chromium even in conditions of low precipitation and obtaining greater values of Ir/Ia as the scanning speed was reduced to the same condition of heat treatment. All these analyzes has confirmed that the EPR- DL portable cell was able to detect the depletionof chromium caused by the presence of deleterious phases, and reflecting the degree of susceptibility to corrosion of SDSS which were studied
A grande demanda por tÃcnicas que consigam detectar e determinar o grau de susceptibilidade à corrosÃo motivou o desenvolvimento de um projeto que resultou na construÃÃo de uma cÃlula portÃtil para a determinaÃÃo do fenÃmeno da sensitizaÃÃo em aÃos inoxidÃveis austenÃticos, a qual foi validada seguindo a norma ASTM A262. O sucesso desta tÃcnica nÃo destrutiva em campo tem motivado a expansÃo dessa tÃcnica de anÃlise para outros materiais e fenÃmenos de precipitaÃÃo. O presente trabalho apresenta a avaliaÃÃo dessa cÃlula portÃtil utilizada em ensaios de EPRâDL para avaliaÃÃo de susceptibilidade a corrosÃo nos AISD UNS S32750 e UNS S32760. Estes materiais foram tratados termicamente a 475ÂC e a 850ÂCem diferentes tempos, criando diferentes padrÃes de precipitaÃÃes de fases deletÃrias para serem detectados pela cÃlula. As soluÃÃes utilizadas foram: 2M de H2SO4+0,01M de KSCN+0,5 M de NaCl (soluÃÃo 1) e 2M de H2SO4+0,01M de KSCN+1,0 M de NaCl (soluÃÃo2) e as velocidades de varreduras estudadas foram de 1,67mV/s, 3,0mV/s e 6,0mV/s. Para comprovar a presenÃa da precipitaÃÃo de fases deletÃrias e associÃ-las ao comportamento eletroquÃmico apresentado pela cÃlula, as amostras tiveram suas microestruturas analisadas por microscopia Ãtica (MO), microscopia eletrÃnica de varredura (MEV),e ensaios com energia dispersiva de raios-X (EDS).TambÃm foram avaliados o consumo da fase ferrita por analise magnÃtica com ferritoscÃpio e realizados ensaios de dureza Vickers para analisar o aumento da dureza devido a precipitaÃÃo das fases deletÃrias. Foi observado por MO, MEV/ EDS, ferritoscÃpio, EPR-DL e por dureza Vickers que quando maior o tempo de tratamento tÃrmico maior foi a quantidade de fases deletÃrias precipitadas. Quanto maior foi o nÃvel de precipitaÃÃo, maiores foram os valores de Ir/Ia e maiores valores de dureza foram obtidos. Os resultados mostraram que a soluÃÃo 2 foi a mais eficaz na detecÃÃo da susceptibilidade a corrosÃo, conseguindo detectar o empobrecimento de cromo mesmo em condiÃÃes de baixa precipitaÃÃo, e obtendo maior valores de Ir/Ia conforme a velocidade de varredura era diminuÃda para uma mesma condiÃÃo de tratamento. Todas essas anÃlises comprovaram que a cÃlula portÃtil de EPR- DL foi capaz de detectar o empobrecimento de cromo ocasionado pela presenÃa das fases deletÃrias, e refletindo o grau de susceptibilidade a corrosÃo dos AISD estudados.

Abstract:
X chromosome inactivation (XCI) is an important mechanism for gene dosage compensation between XY males and XX females during early embryonic development of eutherian mammals. The major regulator of XCI is the long non-coding RNA (lncRNA) X inactive specific transcript (Xist). Xist RNA is believed to recruit epigenetic modifiers and initiate a silencing cascade that alters the chromatin structure and culminates in the transcriptional repression of most genes at the inactive X chromosome (Xi). Though extensively studied, the protein factors involved in the recruitment, spreading and maintenance of Xist RNA at the Xi are largely unknown. Recently published studies provide evidence that the DNA and RNA binding nuclear matrix protein scaffold attachment factor A/heterogeneous ribonucleoprotein U (SAF-A/hnRNP U) is required for Xist localization to the Xi. These studies, however, are incomplete in that they neither provide information on the RNA binding consensus sequence for SAF-A/hnRNP U on Xist, nor on its functional role in XCI. The present study was designed to re-investigate the role of SAF-A/hnRNP U in XCI using state-of-the-art techniques, notably fluorescence recovery after photo-bleaching (FRAP), 3D-structured illumination microscopy (3D-SIM), and in vivo crosslinking and RNA immunoprecipitation (CLIP). The results indicate that SAF-A/hnRNP U exists in two forms; a highly dynamic pan-nuclear protein and a stably Xi-associated form. 3D-SIM reveals that the latter closely associates with Xist RNA, and lines out the interchromatin channels within the Barr body. This finding suggests that SAF-A/hnRNP U takes part in the structural organization of the Xi by creating a secluded chromatin environment that retains XCI factors in their dedicated nuclear location. In contrast to observations made in microscopy imaging, biochemical experiments did not confirm a direct binding of SAF-A/hnRNP U to Xist RNA. This observation led to the conclusion that the protein plays an indirect, structural role in XCI.

Abstract:
Strain measurement on blade and the calculation of blade stress during test are critical to determine the actual stress and the life of blades. Since the dynamic loads acting on blades, such as gas pressures and load changes during operation, might not be known, the concept of strain amplification factor (SAF) can be used to estimate the maximum strain/stress of blade during resonance. The SAF is defined as a ratio between the maximum modal strain on blade from FE analysis and the measured strain or computed strain of a particular place on blade. In this paper, this concept is reviewed and further analysis is carried out. To verify the theoretical analysis, the experimental tests of a radial turbine (blisk) are performed in detail. However, only experiments in static condition are considered in this work, since a better experimental condition can be achieved. Moreover, the verification of rotating blades could be accomplished with the similar procedure. The FE method is chosen as a tool to provide theoretical results. Two computations by using FE method are performed to obtain the SAFs. The first computation considers the use of sector model of turbine, which is usually practiced in industry. In the second calculation, the complete tuned turbine is taken into account. The obtained results for both computations and the effect of mistuning on SAF are discussed. Furthermore, the computed SAFs are compared to the experimental results.

Abstract:
Although the design and applications of linear tuned mass damper (TMD) systems are well developed, nonlinear TMD systems are still developing. In this paper, the application of multiple semi-active friction tuned mass dampers (SAF-MTMD) for response control of a multistory structure under seismic excitation is investigated. The friction forces of the SAF-MTMD are controllable. A non-sticking friction (NSF) controller, which is able to keep each of the TMD activated and in its slip state throughout an earthquake with arbitrary intensity, was conducted. A parametric study is performed to investigate the effectiveness of SAF-MTMD. The seismic performance of the SAF-MTMD is also compared with the single and multiple passive friction tuned mass dampers (PF-TMD/PF-MTMD). The numerical result shows that the SAF-MTMD is superior to PF-MTMD in reducing the response of the primary structure under the seismic excitation.

Abstract:
Introdução: As mulheres grávidas têm um risco quatro vezes maior para tromboembolismo em comparação a mulheres não grávidas. Entre as pacientes que apresentam trombose arterial e/ou venosa recorrente, recomenda-se a pesquisa de anticorpos antifosfolípides (aPL), como anticorpo anticardiolipina, anticoagulante lúpico, antibeta2 glicoproteína I, para o diagnóstico da Síndrome Antifosfolipídeo (SAF). Objetivo: Comparar os resultados gestacionais de pacientes que apresentaram trombose venosa profunda (TVP) sem aPL com pacientes com SAF com história de trombose vascular. Métodos: Estudo de coorte com gestantes acompanhadas em um pré-natal de alto risco que apresentaram trombose vascular. As pacientes foram divididas em dois grupos: o primeiro consistiu em gestantes que apresentaram trombose vascular com pesquisa para SAF negativa; e o segundo, pacientes com SAF. Materiais e Métodos: Coleta de dados nos prontuários, por meio de um questionário redigido pelos próprios autores. Resultados e Conclusão: Cento e cinquenta e três pacientes com trombose vascular foram incluídas no presente estudo, sendo 108 com história de trombose com aPL negativos (grupo 1) e 45 com aPL positivos (grupo 2), confirmando o diagnóstico de SAF. O grupo 2 tinha história obstétrica desfavorável em comparação com o grupo 1 (passado de 19 natimortos e 38 abortos e atuais 4 óbitos fetais no grupo 2 versus 2 óbitos fetais e 44 abortos no grupo 1). Pacientes com trombose e aPL positivos (grupo 2) apresentaram com maior frequência na gestação atual crescimento intrauterino restrito (15×4, p<0,001), parto prematuro (17 versus 8, p<0,001), oligodramnia (6 versus 2, p=0,008) e pré-eclâmpsia (9 versus 7, p=0,01). O peso médio do nascimento (2566±677 versus 3218±496, p<0,001) e a idade gestacional (36,02±3,9 versus 38,32±1,39, p<0,001) no parto foram significativamente menores no grupo 2. Conclusão: A presença de aPL em pacientes com história de trombose está associada a piores resultados gestacionais, incluindo maior incidência de pré-eclâmpsia, parto prematuro e menor peso ao nascer; enquanto a história de TVP com pesquisa para aPL negativa apresentou resultados gestacionais favoráveis. Nosso estudo sugere que a investigação para SAF é fundamental para o acompanhamento adequado de gestante com história de trombose vascular.

Abstract:
Confirmed coronavirus cases in Africa in early November 2020 exceeded 1.8 million, with 45% occurring in Southern Africa (SAF). Most SAF countries lack the capacity to adequately protect lives and livelihoods. High indebtedness means underfunded essential services, and most countries had just emerged from a severe food crisis and the effects of Cyclone Idai. Donors must go beyond temporary debt service suspension and provide new aid grants. SAF governments must not use the pandemic to restrict civil society advocacy on behalf of the most vulnerable people.
