Abstract:
The field experiment was conducted at wheat research farm of CCS Haryana Agriculture University during Rabi season of 2019-20 to study nitrogen nutrition through organic and inorganic source of fertilizer on growth phenology, yield and quality of wheat (Triticum aestivum L.) The experiment was laid out in randomized block design with three replications containing 16 treatments combination i.e T1-Control; T2-100% RDN through urea; T3- 100% RDN through FYM; T4-100% RDN through vermicompost; T5-50% RDN through urea+ 50% RDN through FYM; T6-50% RDN through urea+ 50% RDN through vermicompost; T7-25% RDN through urea+ 75% RDN through FYM; T8-25% RDN through urea 75% RDN through vermicompost; T9-100% RDN through urea + Azotobacter; T10-100% RDN through FYM + Azotobacter; T11-100% RDN through vermicompost + Azotobacter; T12-50% RDN through urea+ 50% RDN through FYM + Azotobacter; T13-50% RDN through urea+ 50% RDN through vermicompost + Azotobacter; T14-25% RDN through urea+ 75% RDN through FYM + Azotobacter; T15-25% RDN through urea+ 75% RDN through vermicompost + Azotobacter; T16- Azotobacter. Treatment T9, 100% nitrogen nutrition through chemical fertilizer (urea) with seed treatment of Azotobacter has taken significantly maximum days to emergence (5.3). Days taken to 50% spike emergence (94.7) and days taken to maturity (148.0) respectively. Similarly T9 had significantly higher grain yield (5640 kg/ha), hectoliter weight (83.167 kg/ha), grain appearance score (7.933 scale/10) and protein content (12.90 %) of wheat during the research period respectively.

Abstract:
OBJECTIVES/SPECIFIC AIMS: We have reported that radiofrequency renal denervation (RF-RDN) in SHR at 20-weeks of age, decreased blood pressure (BP) and fibrosis in kidney cortex and medulla when rats were sacrificed at 6 months. However, whether RF-RDN can have similar benefits in older rats remains unknown. This study examined whether performing RF-RDN in older rats also has a beneficial effect on BP and renal fibrosis. METHODS/STUDY POPULATION: Baseline systolic and diastolic BP (SBP/DPB) was measured (telemetry) in nine-month-old SHR and Wistar Kyoto rats (WKY). Groups of rats then received bilateral RF-RDN or Sham-RDN (SHR-RDN, n=9; SHR-Sham, n=10; WKY-RDN, n=5; WKY-Sham, n=8). Rats were then sacrificed at 12-months of age. Kidneys were harvested, sectioned, and assessed for fibrosis by Masson’s trichrome stain. A pathologist, who was blinded to treatment groups, evaluated each kidney section for fibrosis. RESULTS/ANTICIPATED RESULTS: Compared to SHR with Sham-RDN, RF-RDN prevented a further increase in systolic and diastolic BP from baseline (9-month) in SHR as they aged to 12-months (SHR-Sham mmHg: 9-month 193±4/127±4; 12-month 207±3/142±5; SHR-RDN mmHg: 9-month 197±3/132±2; 12-month 197±4/132±3). RF-RDN did not alter SBP or DBP in aged WKY. One-year-old SHR with prior Sham-RDN showed extensive renal fibrosis in kidney cortex and medulla. In contrast, RF-RDN significantly decreased renal fibrosis in the medulla, but not cortex. There was no fibrosis in kidneys of age matched WKY. DISCUSSION/SIGNIFICANCE OF IMPACT: These findings suggest that RF-RDN may be a potential therapy for halting progression of hypertension and decreasing medullary fibrosis in the aged population.

Abstract:
Background. Changes in the composition and diversity of gut microbiota, which can be altered by autonomic nerve activity, contribute to the development of heart failure (HF). Renal denervation (RDN) can improve cardiac function by reducing sympathetic nerve activity. However, whether the beneficial role of RDN on HF is related to gut microbiota is unknown. Methods. Thirty rats were assigned to a control, HF (with induced transverse aortic constriction (TAC)), RDN (with RDN induced 10 weeks after TAC), Nog (HF rats with Nogo-P4-administered 8 weeks after RDN), and NEP (HF rats with NEP1-40-administered 8 weeks after RDN) group. Then, 16SrRNA amplicon sequencing and analyses of fecal samples were performed. Results. Beta diversity analyses revealed that compared to the HF group, the RDN, Nog, and NEP groups clustered closer to the control group. The Firmicutes/Bacteroidetes ratio was reduced in the HF group (1.59) compared with the control group (3.21) and was significantly decreased compared to the Nog (7.19), RDN (6.20), and NEP (4.42) groups. At the genus level, the HF group showed decreased abundances of Lactobacillus and Alistipes and increased abundances of Bacteroides and Clostridium compared with the control group. The abundances of Lactobacillus and Alistipes were increased, and those of Bacteroides and Clostridium were decreased in the RDN, Nog, and NEP groups compared to the HF group. However, no differences were observed between the three groups that underwent RDN. The microbial function showed the same tendency. Conclusions. RDN reversed the abnormal changes in the gut microbiome in HF rats. Inhibition of reinnervation after RDN did not affect intestinal bacteria.

Abstract:
Background: The Symplicity-HTN 3 trial failed to show significant difference in blood pressure (BP) lowering between patients undergoing catheter-based renal denervation (RDN) and the sham-procedure arm of the study. However, there is still optimism about the role of RDN in the treatment of resistant hypertension, because identification of patients with increased sympathetic activity thus being good RDN responders, improvements in the RDN procedure and new technology RDN catheters are all expected to lead to better RDN results. We present our initial experience with RDN for the treatment of resistant hypertension, and the utility of novel anesthetics and cardiac 123I-metaiodobenzylguanidine scintigraphy (123I-MIBG). Methods and Results: Seven patients with resistant hypertension underwent RDN and were followed up for 6 months. MIBG was performed before RDN, in order to estimate sympathetic activity and predict the response to RDN. All patients were sedated with dexmedetomidine and remifentanil during RDN. All patients tolerated the procedure well, were hemodynamically stable and their peri-procedural pain was effectively controlled. A median of 7.6 ± 2.1 and 6 ± 1.4 ablations were delivered in the right and left renal artery respectively, making an average of 6.8 burns per artery. No peri-procedural or late complications - adverse events (local or systematic) occurred. At 6 months, mean reduction in office BP was -26.0/-16.3 mmHg (p=0.004/p=0.02), while mean reduction in ambulatory BP was -12.3/-9.2 mmHg (p=0.118/p=0.045). One patient (14.3%) was a non-responder. None of the cardiac 123I-MIBG imaging indexes(early and late heart-to-mediastinum (H/M) count density ratio, washout rate (WR) of the tracer from the myocardium) were different between responders and non-responders. Conclusion: Patients with resistant hypertension who underwent RDN in our department had a significant reduction in BP 6 months after the intervention. 123I-MIBG was not useful in predicting RDN response. Dexmedetomidine and remifentanil provided sufficient patient comfort during the procedure, allowing an adequate number of ablations per renal artery to be performed, and this could probably lead to improved RDN results.

Abstract:
Objectives. We sought to assess acute changes in systemic and pulmonary hemodynamics and microscopic artery lesions following extended renal artery denervation (RDN). Background. RDN has been proposed to reduce sympathetic nervous system hyperactivation. Although the effects of RDN on systemic circulation and overall sympathetic activity have been studied, data on the impact of RDN on pulmonary hemodynamics is lacking. Methods. The study comprised 13 normotensive Landrace pigs. After randomization, 7 animals were allocated to the group of bilateral RDN and 6 animals to the group of a sham procedure (SHAM). Hemodynamic measures, cannulation, and balloon-based occlusion of the renal arteries were performed in both groups. In the RDN group, radiofrequency ablation was performed in all available arteries and their segments. An autopsy study of the renal arteries was carried out in both groups. Results. The analysis was performed on 12 pigs (6 in either group) since pulmonary thromboembolism occurred in one case. A statistically significant drop in the mean diastolic pulmonary artery pressure (PAP) was detected in the RDN group when compared with the SHAM group (change by 13.0 ± 4.4 and 10.0 ± 3.0 mmHg , correspondingly; P = 0.04 ). In 5 out of 6 pigs in the RDN group, a significant decrease in systemic systolic blood pressure was found, when compared with baseline ( 98.8 ± 17.8 vs. 90.2 ± 12.6 mmHg , P = 0.04 ), and a lower mean pulmonary vascular resistance (PVR) ( 291.0 ± 77.4 vs. 228.5 ± 63.8 dyn ∗ sec ∗ c m − 5 , P = 0.03 ) after ablation was found. Artery dissections were found in both groups, with prevalence in animals after RDN. Conclusions. Extensive RDN leads to a rapid and significant decrease in PAP. In the majority of cases, RDN is associated with an acute lowering of systolic blood pressure and PVR. Extended RDN is associated with artery wall lesions and thrombus formation underdiagnosed by angiography.

Abstract:
Green manures can enrich soils with organic matter and nitrogen. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the residual effects of different green manures on the growth and yield of wheat (BARI Gom-26). The experiment containing nine treatments were laid out in a randomized complete block design with three replications. The treatments were T1 [No green manure + 100% Recommended dose of nitrogen (RDN)], T2 (Sesbania aculeata + 75% RDN), T3 (Sesbania aculeata + 50% RDN), T4 (Sesbania rostrata + 75% RDN), T5 (Sesbania rostrata + 50% RDN), T6 (Vigna radiata + 75% RDN), T7 (Vigna radiata + 50% RDN), T8 (Vigna mungo + 75% RDN), and T9 (Vigna mungo + 50% RDN). Residual effects of green manures with RDN significantly increased the yield attributes as well as grain and straw yields of wheat. Further, green manures exerted significant residual effects on grain, straw and total N uptake of wheat. Among various treatments with green manures, the performance of T4 (Sesbania rostrata + 75% RDN) was the best as it produced the highest grain yield (4.28 t ha-1), straw yield (4.74 t ha-1) and total N uptake (108.02 kg ha-1). The use of green manures slightly increased the organic matter content, total N and available P, K, and S contents of the post-harvest soils. As regards to the contribution of various green manures on yield contributing characters and yield of wheat, performances of two Sesbania species viz., S. aculeata and S. rostrata in association with 75% N fertilizer were effective.Asian J.

Abstract:
OBJECTIVES/SPECIFIC AIMS: The goal of this study was to investigate whether RF-RDN attenuates renal fibrosis and inflammation in SHR with established hypertension. METHODS/STUDY POPULATION: Twenty-two-week-old SHR received bilateral RF-RDN or Sham-RDN (Biosense Webster Stockert 70 generator and RF-probe). Four weeks later, SHR were sacrificed and paraffin sections of kidneys were stained for fibrosis by Masson’s trichrome staining. Kidney tissue were homogenized for measurement of cytokines levels by ELISA. RESULTS/ANTICIPATED RESULTS: The results showed that Sham-RDN treated SHR had extensive fibrosis as demonstrated by moderate thickening of Bowman’s capsule, collagen deposition in glomerulus, extensive tubulointerstitial fibrosis, and segmental glomerulosclerosis. In contrast, RF-RDN significantly reduced each of these pathological components of fibrosis in kidney cortex and medulla as compared with Sham-RDN treated kidneys. In other studies, RF-RDN decreased B cells, CD4+ T cells, and CD8+ T cells in the kidney of SHR as measured by flow cytometry. Meanwhile, kidney tissue levels of IL-17, INF-γ, MIP-3a, TNF-α, and TGF-β were decreased as compared with respective levels in Sham-RDN. DISCUSSION/SIGNIFICANCE OF IMPACT: Together, these findings demonstrate that removal of the influence of heightened renal sympathetic activity by RF-RDN decreases kidney inflammatory markers and attenuates renal fibrosis in hypertensive SHR.

Abstract:
Overactivity of renal sympathetic nerves and nitric oxide (NO) deficiency occur in hypertensive chronic kidney disease (CKD). In sheep with hypertensive CKD and NO deficiency, renal denervation (RDN) reduces blood pressure and improves kidney function (glomerular filtration rate). We hypothesized that this improvement in glomerular filtration rate after RDN is associated with increased NO bioavailability. In this study, glomerular filtration rate response to systemic inhibition of NOS (NO synthase) was examined in healthy and CKD sheep at 2 and 30 months after a sham (intact nerves) or RDN procedure. Basal urinary total nitrate (nitrate+nitrite) excretion was examined at 2 and 30 months, and kidney protein expression of endothelial and neuronal NOS was assessed at 30 months. Urinary nitrate+nitrite in CKD-RDN and healthy sheep was ≈50% to 70% greater than in CKD-intact. During NOS inhibition, the fall in glomerular filtration rate in CKD-RDN sheep was ≈20% greater than in CKD-intact. These effects in CKD-RDN sheep were similar to those in healthy sheep. Endothelial NOS protein expression was lower in CKD-intact sheep compared with healthy sheep and compared with CKD-RDN. In summary, RDN normalizes NO bioavailability and restores contribution of NO to renal hemodynamics in CKD. These changes may promote improvements in kidney function and sustained blood pressure lowering after RDN in hypertensive CKD.

Abstract:
Majority of patients with hypertension and chronic kidney disease (CKD) undergoing renal denervation (RDN) are maintained on antihypertensive medication. However, RDN may impair compensatory responses to hypotension induced by blood loss. Therefore, continuation of antihypertensive medications in denervated patients may exacerbate hypotensive episodes. This study examined whether antihypertensive medication compromised hemodynamic responses to blood loss in normotensive (control) sheep and in sheep with hypertensive CKD at 30 months after RDN (control-RDN, CKD-RDN) or sham (control-intact, CKD-intact) procedure. CKD-RDN sheep had lower basal blood pressure (BP; ≈9 mm Hg) and higher basal renal blood flow (≈38%) than CKD-intact. Candesartan lowered BP and increased renal blood flow in all groups. 10% loss of blood volume alone caused a modest fall in BP (≈6–8 mm Hg) in all groups but did not affect the recovery of BP. 10% loss of blood volume in the presence of candesartan prolonged the time at trough BP by 9 minutes and attenuated the fall in renal blood flow in the CKD-RDN group compared with CKD-intact. Candesartan in combination with RDN prolonged trough BP and attenuated renal hemodynamic responses to blood loss. To minimize the risk of hypotension-mediated organ damage, patients with RDN maintained on antihypertensive medications may require closer monitoring when undergoing surgery or experiencing traumatic blood loss.

Relevance of work. Balancing electricity in the new electricity market is one of the pressing issues. In addition to more clearly forecasting, balancing groups have been created to minimize them, so a balancing method has been developed to maximize the reduction of imbalances. The rationality of the use of balancing electricity depends largely on the volume of consumption of the enterprise and the availability of the Automated System of Commercial Electricity Metering (ASCOE) . hour, thereby it will be beneficial for enterprises that have less or more consumption from a given range. Also, to reduce losses, the issue is considered from a financial point of view, namely forecasting pricing. To do this, the analysis of time series is carried out to determine the pricing of electricity .

Abstract:
Nesta tese investigamos o estado normal (T > Tc) dos Yba2Cu3O6+x supercondutores de alto Tc. As técnicas da RMN e RQN foram empregadas para estudar as respostas estática e dinâmica do sistema de spins eletrônicos em função da temperatura, para diversas concentrações de oxigênio: x = 0.5 (cristal 1), 0.92 (cristal 2), 0.94 (cristal 3) e 1.0 (cristais 4 e 5). Focalizando diferentes sítios nucleares a RMN pode fornecer uma informação mais rica da susceptibilidade dinâmica, X (q.w), abrangendo diferentes regiões da Zona de Brillouin (ZB). Com os sítios do 17O(2,3) e do 89Y sensoreamos a região próxima ao centro do ZB, q == 0, enquanto que com o sitio do Cu(2) exploramos o extremo do ZB, (q == QAF). Foi realizado um estudo comparativo da RMN dos sítios do Cu(2), do O(2,3) e do Y sobre o cristal 1. Da comparação entre os deslocamentos hiperfinos magnéticos do Y e do O(2,3) extraímos as contribuições orbitais e as constantes de acoplamento hiperfino do Y. A razão entre as relaxações spin-rede do O(2,3) e do Y mostrou-se independente da temperatura, e próxima do esperado teoricamente a partir das constantes hiperfinas no cenário do hamiltoniano de Mila e Rice. Questões como a dependência da taxa de relaxação spin-rede (T1-1) com a intensidade do campo e a anisotropia da susceptibilidade estática de spin foram estudadas sobre o cristal 2. Acima de Tc, para o Cu(2), não foi encontrada nenhuma dependência de T1 com a intensidade do campo. Os resultados sobre o Y indicam uma anisotropia da susceptibilidade e do tensor de acoplamento hiperfino. Uma extensa comparação entre os resultados da RMN e da Difusão Inelástica de Nêutrons (DIN) foi realizada sobre as mesmas amostras (cristais 4 e 5), fato inédito ate então. Propõe-se um modelo gaussiano para X\"~q,o», compatível com as experiências de nêutrons, no qual o comprimento de correlação ~ foi fixado pelos resultados da DIN sobre o cristal 2. Analisando a relaxação spin-spin do Cu(2), 63(T2g)-1, em função deste modelo, extraímos a susceptibilidade estática X\'(q=QAF) em unidades absolutas e encontramos um fator de Stoner X\'(q=QAF) / X\'(q=O) ~ 10. Da análise conjunta de 63(T1T)-1 e 63 (T2g)-1 obtivemos a energia característica das flutuações AF, rAF::::3:0meV, em excelente acordo com a DIN. Estes mesmos resultados permitiram evidenciar, exclusivamente através do RMN, quando ocorre a abertura de um gap de spin. Neste trabalho mostramos que resultados da DIN são compatíveis com a RMN para o sitio do Cu(2), porem, sérias dificuldades são encontradas para explicar os resultados sobre os sítios do Y e, principalmente, do O(2,3). As alternativas para este problema são discutidas. Os resultados obtidos nesta tese levaram ao estabelecimento de um diagrama de fase, segundo a RMN, do estado normal dos Yba2Cu3O6+x supercondutores, cobrindo do regime sub-dopado ao regime sobre-dopado, passando pela composição de dopagem ótima.
The normal state(T > Tc) of the high Te superconducting Yba2Cu3O6+x was studied. The NMR and NQR techniques were employed in order to investigate the static and dynamic responses of the electronic spin system as function of temperature, for the following oxygen contents: x = 0.5 (crystal 1), 0.92 (crystal 2), 0.94 (crystal 3) e 1.0 (crystals 4 and 5). Focusing various nuclear sites the NMR could give a more rich information of the dynamical susceptibility, X(q,ffi), probing different regions of the Brillouin Zone (ZB). With 17O(2,3) and 89Y sites the BZ center, q:: 0, was studied, while with the Cu(2) site it was the BZ extreme, (q:: QAF) that was investigated. In crystal 1 we have compared the NMR of the Cu(2), O(2,3) and Y sites. From the comparison between the Y and O(2,3) magnetic hyperfine shift we have extracted the orbital contributions and the Y hyperfine coupling tensor. The ratio between the O(2,3) and Y nuclear spin lattice relaxation rate was found to be temperature independent, and its value was in fair agreement with what it was expected theoretically from the coupling constants within the picture of the Mila-Rice Hamiltonian. Problems such as the field intensity dependence of the spin-lattice -relaxation rate (T1-1) and the anisotropy of the static susceptibility where investigated in crystal 2. Above Tc, for the Cu(2) site, we have not found any field dependence of T1. Our results on the Y site indicate an anisotropy of both the static susceptibility and the Y coupling tensor. An extensive comparison between the NMR and the Inelastic Neutron Diffusion (IND) results was done in the very same samples, crystals 2 and 4. In accordance to neutron data a Gaussian model for X\"AF( q,ro) is proposed, in which the coherence length ~ was fixed by the IND results in crystal 2. Analyzing the Cu(2) nuclear spin-spin relaxation rate, 63(T2g)-1, as function of this model, we have extracted the staggered susceptibility X\'(q=QAF) in absolute units, finding a Stoner factor X \'( q=QAF) / X\'( q=O) ~ 10. From the analysis of 63(T1T)-1 together with 63(T2g)-1 we have obtained the AF characteristic energy, rAF ::::l 30meV, in excellent agreement with IND. These results provided us a powerful method to evidence the opening of a spin pseudo gap, exclusively from the NMR results. A consistent picture arise from the comparison between IND and the Cu(2) NMR. In contrast, it is hard to explain the Y and, specially, the O(2,3) results within this same picture. The theoretical alternatives to this puzzle are discussed. The whole set of results we have obtained led us to propose a NMR based phenomenological phase diagram for the normal state of the superconducting Yba2Cu3O6+x, covering from the under doped regime to the over doped regime, passing through the optimal doping.

A estirpe probiótica Lactobacillus UFV H2b20, previamente classificada como Lactobacillus acidophilus por suas características de fermentação de açúcares, apresentou-se mais semelhante à espécie Lactobacillus delbrueckii, quanto à seqüência de rDNA 16S, o que levou ao questionamento acerca da identidade da linhagem. Para o esclarecimento da real classificação da linhagem, o método de hibridização DNA-DNA foi empregado. A linhagem apresentou 75,2% e 77,4% de reassociação com L. delbrueckii subsp. lactis (ATCC 12315) e L. delbrueckii subsp. delbrueckii (ATCC 9649), respectivamente. Dado que a homologia de 70% ou mais, por esse método, tem sido usada como padrão para agrupamento de bactérias em uma mesma espécie, sugere-se, aqui, que Lactobacillus UFV H2b20 seja, daqui para frente, denominado L. delbrueckii UFV H2b20. Identificada a linhagem, outro objetivo do trabalho era desenvolver um protocolo para detecção in situ de L. delbrueckii. Uma sonda de 26 nucleotídeos (SA) foi construída e testada com outras espécies de Lactobacillus relacionadas geneticamente entre si. Estes estudos demonstraram que a seqüência de assinatura (SA) estava presente em L. delbrueckii UFV H2b20, L. delbrueckii UFV H2b21, L. delbrueckii subsp. delbrueckii e L. delbrueckii subsp. lactis, o que indica ser ela eficaz para ser usada como sonda para rRNA 16S espécie-específica pelo método de FISH. A hipótese de existência de polimorfismos, levantada em trabalhos prévios no rDNA 16S da linhagem, foi confirmada após as análises dos segmentos de DNA clonados e selecionados do banco genômico construído para a linhagem L. delbrueckii UFV H2b20. As seqüências analisadas demonstraram, também, presença de segmentos correspondentes a quatro genes codificadores de rRNA 16S distintos, e seis segmentos distintos para uma mesma região de rRNA 23S, indicando seis operons putativos. Há evidência de, pelo menos, um operon putativo completo seguido de região codificadora de seis tRNAs. Não se detectou região espaçadora longa entre rDNA 16 e 23S.
Lactobacillus UFV H2b20, a probiotic strain, previously identified as Lactobacillus acidophilus due to its sugar fermentation pattern, was found to be more closely related to Lactobacillus delbrueckii regarding its 16S rDNA sequence. It was demonstrated by DNA-DNA hybridization that this strain presented 75.2% and 77.4% of reassociation with L. delbrueckii subsp. lactis ATCC 12315 and L. delbrueckii subsp. delbrueckii ATCC 9649, respectively. These results place Lactobacillus UFV H2b20 within the L. delbrueckii species, for 70% reassociation as measured by the method used has been a standard to cluster bacteria within the same species. A protocol for in situ detection of L. delbrueckii was developed by means of Fluorescent in situ Hybridization, FISH. A probe consisting of 26 nucleotides labeled with rhodamine was designed based on the signature sequence within the rDNA, and was tested against genetically related Lactobacillus species. A species- specific method was obtained capable of discriminating L. delbrueckii strains from other Lactobacillus species. Previous studies raised the hypothesis of polymorphism among the copies of 16S rDNA in L. delbrueckii UFV H2b20. This was confirmed by sequence analysis of rDNA from a gene library of this strain cloned in phage lambda and subcloned in pBluescript. Sequence analyses of cloned fragments demonstrated the presence of at least four distinct genes encoding 16S rRNAs. Distinct fragments containing 23S rRNA related genes indicated six putative rrn operons. One complete putative rrn operon displays a region encoding 6 different tRNAs. Long spacer regions between 16S and 23S rDNA were not detected.

Abstract:
Une condition préalable pour toute étude d’une protéine par RMN est l’attribution des résonances du spectre 15N-1H HSQC à leurs atomes correspondants du squelette peptidique. Un nouveau type de stratégie d’attribution exploite l’information donnée par une structure 3D déjà disponible de la même protéine ou d’une protéine homologue. Jusqu’à présent, les algorithmes, développés autour de cette stratégie, ont deux inconvénients majeurs : ils ne peuvent pas garantir l’exactitude de l’attribution et ils ne sont pas applicables à des protéines de grande taille. Dans un premier temps, il est montré que l’utilisation des couplages dipolaires résiduels (RDC) pour l’attribution basée sur la structure peut poser des problèmes, notamment liée à l’estimation du tenseur d’alignement. Une nouvelle méthode d’attribution basée sur la structure, nommée NOEnet, est présentée ici. NOEnet n’est pas basée sur les RDCs mais sur les effets Overhauser nucléaire (NOEs). RDCs, déplacements chimiques (CS) et presque tout type de donnée peuvent être inclus dans NOEnet grâce à une approche générale de filtre. NOEnet exploite le réseau de contraintes NOE HN-HN non ambiguës en réalisant une recherche exhaustive de tous les appariements possibles entre le réseau des NOEs et le réseau de la structure 3D. Son algorithme efficace de recherche complète garantit l’exactitude du résultat d’attribution. NOEnet a été testé avec succès sur plusieurs protéines jusqu’à 28 kDa, en utilisant uniquement des données NOE ou une combinaison de données NOE, RDC et CS
A prerequisite for any protein study by NMR is the assignment of the resonances from the 15N-1H HSQC spectrum to their corresponding atoms of the protein backbone. A new type of assignment strategy exploits the information given by an already available 3D structure of the same or a homologous protein. Up to now, the algorithms that have been developed around this strategy have two important drawbacks: they cannot guarantee the accuracy of the assignment and they are not applicable to large proteins. First is shown that the use of residual dipolar couplings (RDC) for the structure based assignment can be problematic, especially the estimation of the alignment tensor is difficult. A novel structure based assignment approach, called NOEnet, is presented here. NOEnet is not based on RDCs but on Nuclear Overhauser Effects (NOEs). RDCs, chemical shifts (CS) and almost any kind of data can be included in NOEnet through a general filter approach. NOEnet exploits the network property of unambiguous HN-HN NOE constraints to realize an exhaustive search of all matching possibilities of the NOE network on the structural one. Its efficient complete search algorithm ensures the correctness of the assignment results. NOEnet has been successfully tested on several proteins up to 28 kDa, using only NOE data or a combination of NOE, RDC and CS data

Les méthodes RMN multidimensionnelles requises pour l'obtention d'une résolution atomique élevée sont relativement couteuses en temps expéri- mental, ce qui complique considérablement leur application à l'analyse d'échantillons en temps réel. La première partie de cette thèse traite des pro- grès récents dans le domaine de l'acquisition rapide des spectres de RMN . La deuxième partie concerne la paroi cellulaire des bactéries Gram-négatives et Gram-positives. En raison de son poids moléculaire élevé et de son car- actère non cristallin, nous avons appliqué la RMN du solide pour l'étudier. La qualité exceptionnelle des spectres de RMN solide permet l'étude, à résolution atomique, de la structure et de la dynamique du peptidoglycane et des acides téchoïques qui se lient de manière covalente au peptidoglycan (WTA). La détermination des propriétés dynamiques du peptidoglycane est aussi utilisée pour étudier les interactions entre protéines et peptidoglycane et la complexation avec des ions divalents.

Abstract:
O nucléolo é uma organela subnuclear formada pela atividade transcricional dos genes ribossomais 18S-5.8S-26S (rDNA 45S) e consequente biogênese dos ribossomos. A atividade destes genes resulta na região organizadora do nucléolo (NOR), na forma de uma constrição secundária em cromossomos metafásicos. As constrições secundárias se condensam progressivamente durante a mitose e se descondensam ao final da telófase quando a reestruturação do nucléolo se inicia. Genomas que apresentam mais de um locus de rDNA 45S deve apresentar, obrigatoriamente, pelo menos um par de NORs, enquanto os demais loci poderão ou não serem expressos. O controle da expressão dos genes ribossomais e a formação da cromatina nucleolar são modulados por eventos epigenéticos. Embora alguns pontos sobre o funcionamento dos genes ribossomais e a formação do nucléolo estejam bem estabelecidos, questões como o padrão de condensação da cromatina nucleolar durante a mitose, o padrão de funcionamento de sítios adicionais de genes ribossomais, o papel das modificações epigenéticas na dinâmica da cromatina nucleolar e na expressão do rDNA 45S e o mecanismo de herança dos genes ativos, permanecem abertas. A espécie Crotalaria juncea (Leguminosae-Papilionoideae), com 2n=2x=16 cromossomos, que possui um locus de rDNA 45S no braço curto do cromossomo 1, que sempre forma constrição secundária, e um sítio adicional com atividade facultativa no braço curto do cromossomo 4, é um excelente modelo para o estudo destas questões. No contexto apresentado, foram estudadas a dinâmica de condensação das NORs durante o ciclo celular e sua correlação com a atividade dos genes ribossomais, incluindo o locus adicional, e ainda o papel da metilação da citosina do DNA durante estes processos. Os resultados demonstram que a cromatina da região organizadora do nucléolo segrega em um estado descondensado durante a mitose, na forma de constrição secundária, ou seja, tal estrutura não se condensa durante a metáfase e não volta a se distender no início da telófase. Aparentemente, o que causa correlações equivocadas entre a atividade nucleolar e a observação morfológica da constrição secundária na metáfase é a contração forçada da cromatina da NOR causada por agentes antimitogênicos. Este modelo de segregação em um estado aberto pode ser explicado pela descrição de diversas proteínas que permanecem diretamente ligadas ou indiretamente associadas à região da NOR durante a mitose, funcionando como uma barreira física para a compactação. Ambos os sítios, principais e adicionais, do rDNA 45S presentes em Crotalaria juncea apresentam atividade transcricional, embora o locus do cromossomo 4 mostre atividade facultativa. Ao contrário do que foi anteriormente proposto, uma vez ativo, o locus adicional permanece descondensado durante todo o ciclo mitótico, seguindo o mesmo comportamento dos sítios principais. As constrições secundárias e a cromatina nucleolar são hipermetiladas em nível citológico, independentemente de sua atividade. A aparente hipometilação observada no rDNA 45S em cromossomos mitóticos e núcleos interfásicos se deve ao menor grau de compactação da região organizadora do nucléolo e, consequentemente, à baixa densidade de cromatina.
The nucleolus is a subnuclear organelle formed as a result of transcriptional activity of ribosomal RNA genes 18S-5.8S-26S (45S rDNA) and subsequent ribosome biogenesis. This activity forms the nucleolar organizing region (NOR) as a secondary constriction in metaphase chromosomes. The secondary constrictions progressively condense during mitosis and decondense at the end of telophase, when nucleoli start to reassemble. Genomes presenting more than one 45S rDNA locus must have at least one pair of NOR bearing chromosomes, while other loci may be expressed or not. Ribosomal gene expression and nucleolar chromatin assembly are modulated by specific epigenetic events. Although some topics related to rDNA gene activity and nucleolus formation are well understood, questions such as the behavior of nucleolar chromatin condensation during mitosis, standard functions associated with rDNA additional sites, role of epigenetic modifications in nucleolar chromatin and 45S rDNA expression processes, and inheritance mechanism of active genes, remain to be solved. Crotalaria juncea (Leguminosae - Papilionoideae) has 2n=2x=16 chromosomes and carries a 45S rDNA locus at the short arm of chromosome 1, always presenting a secondary constriction, and an additional site with facultative activity at the short arm of chromosome 4, being an excellent model to resolve these questions. Thus, this study aimed to study NOR condensation dynamics during the cell cycle and its correlation with ribosomal gene activity, including the additional locus, while analyzing the role of rDNA cytosine methylation during this process. The results show that NOR chromatin segregate in a decondensed way throughout mitosis, as a secondary constriction. In other words, this structure does not condense during metaphase and the NOR is not reassembled at the beginning of telophase. Misinterpretations relating nucleolar activity with morphological observations of secondary constrictions, appear to be induced by the artificial contraction of NOR chromatin caused by antimitotic drugs. This segregation model in an open state may be supported by strong diversity of proteins that are maintained attached to NORs during mitosis, serving as a physic barrier for condensation. Both principal and additional 45S rDNA sites of C. juncea are transcriptionally active, although the additional locus in chromosome 4 presented facultative activity depending upon ribosomal request. Unlike what was previously proposed, once the additional site is activated, it remains in an open configuration throughout the cell cycle, similarly to principal site behavior. Secondary constrictions and nucleolar chromatin are hypermethylated at cytological level, regardless of their activity. The seeming hipomethylated state of 45S rDNA in interphase nucleus and mitotic chromosomes is due to a lower compaction level of nucleolar organizing regions and subsequent low chromatin density.

Abstract:
Grande parte das atuais soluções adotadas no provimento de qualidade de serviço em redes é fortemente baseada no protocolo MPLS, que permite a associação de serviços de QoS para diferentes classes de tráfego. Apesar dos seus benefícios, tais soluções apresentam altos custos de OPEX e CAPEX. Redes Definidas por Resíduos (RDN) surgem na perspectiva de viabilizar soluções de baixo custo para o encaminhamento de pacotes baseado simplesmente em operações de resto da divisão (i.e., resíduo). Este trabalho apresenta um modelo para o aprovisionamento de QoS por rótulos programáveis para RDNs. O modelo foi implementado através da linguagem P4. Testes de emulação foram realizados avaliando métricas de QoS e QoE, demonstrando a viabilidade do modelo, mas principalmente ganho na programabilidade de garantias de QoS ajustadas sob demanda.

Abstract:
While learning based depth estimation from images/videos has achieved substantial progress, there still exist intrinsic limitations. Supervised methods are limited by a small amount of ground truth or labeled data and unsupervised methods for monocular videos are mostly based on the static scene assumption, not performing well on real world scenarios with the presence of dynamic objects. In this paper, we propose a new learning based method consisting of DepthNet, PoseNet and Region Deformer Networks (RDN) to estimate depth from unconstrained monocular videos without ground truth supervision. The core contribution lies in RDN for proper handling of rigid and non-rigid motions of various objects such as rigidly moving cars and deformable humans. In particular, a deformation based motion representation is proposed to model individual object motion on 2D images. This representation enables our method to be applicable to diverse unconstrained monocular videos. Our method can not only achieve the state-of-the-art results on standard benchmarks KITTI and Cityscapes, but also show promising results on a crowded pedestrian tracking dataset, which demonstrates the effectiveness of the deformation based motion representation.
