Soybean resistance to Phakopsora pachyrhizi, the cause of soybean rust, has been characterized by the following three infection types: (i) immune response (IM; complete resistance) with no visible lesions, (ii) resistant reaction with reddish brown (RB) lesions (incomplete resistance), and (iii) susceptible reaction with tan-colored (TAN) lesions. Based on visual assessments of these phenotypes, single gene resistance in soybean to P. pachyrhizi has been documented, but colonization within infected tissues based on fungal DNA (FDNA) levels in different soybean genotypes had not been analyzed. The research used a quantitative polymerase chain reaction (Q-PCR) assay to compare visual disease assessment to FDNA in controlled inoculation experiments using two isolates of P. pachyrhizi. The objective of the first experiment was to compare data from digital visual disease assessment to FDNA from Q-PCR assays using digital visual disease assessment using five resistant soybean genotypes (one IM and four RB) and five susceptible genotypes (TAN). The objective of the second experiment was to quantify FDNA using Q-PCR at different time points after inoculation to determine if levels of fungal colonization differed in five soybean genotypes with different levels of resistance (one IM, two RB, and two TAN). For experiment 1, the numbers of uredinia and uredinia per lesion on four of the five resistant soybean genotypes were lower (P < 0.05) than the other six genotypes. Significant differences (P < 0.05) in FDNA concentrations were found among soybean genotypes with TAN lesions and among soybean genotypes with RB lesions. Soybean cultivar UG5 (IM phenotype) had significantly less (P < 0.05) FDNA than all of the other genotypes. Some genotypes that produced TAN lesions had significantly lower (P < 0.05) or non-significantly different FDNA concentrations compared to those genotypes that produced RB lesions. For experiment 2, the regression of FDNA on days after inoculation was significant (P < 0.01) with positive slopes for all genotypes except for UG5, in which FDNA declined over time, indicating a reduction of fungal colonization. The results of this Q-PCR FDNA screening technique demonstrates its use to distinguish different types of resistance, and could be used to facilitate the evaluation of soybean breeding populations, where precise quantification of incomplete and/or partial resistance is needed to identify and map quantitative trait loci.

ABSTRACT In recent years, there has been increased interest in the use of male-specific or F+ coliphages as indicators of microbial inputs to source waters. Sero- or genotyping of these coliphages can also be used for microbial source tracking (MST). Among the male-specific coliphages, the F+ RNA (FRNA) viruses are well studied, while little is known about the F+ DNA (FDNA) viruses. We have developed a reverse line blot hybridization (RLB) assay which allows for the simultaneous detection and genotyping of both FRNA as well as FDNA coliphages. These assays included a novel generic duplex reverse transcription-PCR (RT-PCR) assay for FRNA viruses as well as a generic PCR for FDNA viruses. The RT-PCR assays were validated by using 190 field and prototype strains. Subsequent DNA sequencing and phylogenetic analyses of RT-PCR products revealed the classification of six different FRNA clusters, including the well-established subgroups I through IV, and three different FDNA clusters, including one (CH) not previously described. Within the leviviruses, a potentially new subgroup (called JS) including strains having more than 40% nucleotide sequence diversity with the known levivirus subgroups (MS2 and GA) was identified. We designed subgroup-specific oligonucleotides that were able to genotype all nine (six FRNA, three FDNA) different clusters. Application of the method to a panel of 351 enriched phage samples from animal feces and wastewater, including known prototype strains (MS2, GA, Qβ, M11, FI, and SP for FRNA and M13, f1, and fd for FDNA), resulted in successful genotyping of 348 (99%) of the samples. In summary, we developed a novel method for standardized genotyping of F+ coliphages as a useful tool for large-scale MST studies.

The effect of prostaglandins (PGs) on proximal sodium reabsorption has not been fully defined. The objective of the present study was to determine the response of proximal tubular sodium reabsorption to infusions of arachidonic acid and specific PGs into the renal interstitium in rats. Renal interstitial infusions of arachidonic acid as well as the individual PGs, I2, E2, and F2 alpha, were employed to elevate the concentration of these PGs in the kidney. Infusion of 10(-4) M arachidonic acid elicited a marked increase of urinary excretion of 6-keto-PGF1 alpha (a stable metabolite of PGI2) from 260.1 +/- 52.7 to 507.4 +/- 129.5 pg/min (P less than 0.05) and a smaller increase of PGE2 from 18.4 +/- 11.2 to 25.9 +/- 10.9 pg/min (P less than 0.05). When micropuncture samples were obtained from superficial late proximal tubules, infusion of arachidonic acid increased the fractional delivery of sodium (FDNa) from 47.8 +/- 5.9 to 58.3 +/- 4.6% (n = 6, P less than 0.01). In the presence of indomethacin, arachidonic acid failed to augment FDNa. Infusion of 10(-5) M PGI2 also increased FDNa from 51.4 +/- 3.4 to 64.0 +/- 4.4% (n = 10, P less than 0.01). PGF2 alpha did not change FDNa and PGE2 decreased it from 53.1 +/- 5.4 to 37.4 +/- 3.3% (n = 8, P less than 0.01). In summary, the present study demonstrates that renal interstitial infusion of arachidonic acid decreases sodium reabsorption by the superficial proximal tubules possibly through the stimulation of PGI2 production.

The relationship between the concentration of soil DNA and microbial biomass, determined by the method of substrate-induced respiration was studied in a wide range of soils differing in particle size distribution, acidity, organic carbon content, microbial biomass, and type of human activity in antiquity and present time. Calcaric Leptosols and Leptic Phaeozems of medieval agricultural lands in the Central Caucasus, Stratozems of agricultural terraces of the late Middle Ages – Modern times in the middle mountain zone of the Eastern Caucasus, as well as Kashtanozems and Solonetzes with different grazing intensity in the dry steppe zone (Rostov region) were chosen as the key sites. It has been shown that the determination of soil dsDNA concentration is a reliable and simple method for determining microbial biomass in soils with a loam texture, organic carbon content less 2%, and microbial biomass less 700 µg C/g of dry soil. The conversion factor FDNA in such soils varied in a narrow range from 5.24 to 5.41. In soils with a high content of organic carbon, an increase of FDNA (6.56 and 10.56) was observed due to the presence of recalcitrant e-xtracellular DNA. Agristratified soil of sandy loam texture was characterized by a lower degree of preservation of dsDNA, which resulted in a decrease in the determined microbial biomass (FDNA = 4.22). A reduced conversion factor FDNA (4.78) was also found in the soils of pastures in the dry steppe zone, which confirms the known limitations of using the substrate-induced respiration method in alkaline soils. Human activity does not significantly affect the relationship between the amount of soil DNA and microbial biomass.

Satellite navigation systems are running in complex electromagnetic and space environment. There is few research studies the threat and protect ability of navigation system. Lacking of qualitative data makes it difficult to analyse the security of it. In this paper, we applied Functional Dependency Network Analysis (FDNA) to solve this problem. FDNA studies how the impact caused directly by attack spreads in the overall system through the dependencies between function nodes of system. Then we are able to assess the operability of the application of navigation system. This method avoid considerable statistic experiments. Make full use of principle data. Provide constructive decision making comments.

Background: In the past, many studies suggested a crucial role for dysbiosis of the gut microbiota in the etiology of Crohn’s disease (CD). However, despite being important players in host–bacteria interaction, the role of bacterial membrane vesicles (MV) has been largely overlooked in the pathogenesis of CD. In this study, we addressed the composition of the bacterial and MV composition in fecal samples of CD patients and compared this to the composition in healthy individuals. Methods: Fecal samples from six healthy subjects (HC) in addition to twelve CD patients (six active, six remission) were analyzed in this study. Fecal bacterial membrane vesicles (fMVs) were isolated by a combination of ultrafiltration and size exclusion chromatography. DNA was obtained from the fMV fraction, the pellet of dissolved feces as bacterial DNA (bDNA), or directly from feces as fecal DNA (fDNA). The fMVs were characterized by nanoparticle tracking analysis and cryo-electron microscopy. Amplicon sequencing of 16s rRNA V4 hypervariable gene regions was conducted to assess microbial composition of all fractions. Results: Beta-diversity analysis showed that the microbial community structure of the fMVs was significantly different from the microbial profiles of the fDNA and bDNA. However, no differences were observed in microbial composition between fDNA and bDNA. The microbial richness of fMVs was significantly decreased in CD patients compared to HC, and even lower in active patients. Profiling of fDNA and bDNA demonstrated that Firmicutes was the most dominant phylum in these fractions, while in fMVs Bacteroidetes was dominant. In fMV, several families and genera belonging to Firmicutes and Proteobacteria were significantly altered in CD patients when compared to HC. Conclusion: The microbial alterations of MVs in CD patients particularly in Firmicutes and Proteobacteria suggest a possible role of MVs in host-microbe symbiosis and induction or progression of inflammation in CD pathogenesis. Yet, the exact role for these fMV in the pathogenesis of the disease needs to be elucidated in future studies.

Introduction. The current, rapidly changing world is faced with global changes taking place in various spheres of human activity and bearing a spiritual, moral, ontological character. Insufficient level of spiritual and moral culture, uncertainty in the choice of life-meaning orientations, change of value attitudes, manifestation of egocentricity generates quasi-needs and destructive behavior among students. This is the reason for the problem of studying the prevention of destructive behavior of students, which has become particularly relevant. The purpose of the article is to test a practice–oriented model of prevention of destructive behavior of students in the process of formation of spiritual and moral culture (PDPO in the process of FDNA). Materials and methods. The study involved 287 5th grade students and 48 teachers of the educational organization of the city of Krasnodar (Russian Federation). The research methods are based on a rational combination of theoretical and experimental methods of studying objects corresponding to the set goals and objectives, aimed at determining the level of development of spiritual and moral qualities, the formation of vital functions in students, their value orientations and destructive manifestations (test «Value orientations» by M. Rokich; card «Spiritual and moral development of a student» by V.I. Andreev; diagnostic card of readiness of a student and a teacher to prevent destructive behavior in the process of forming a spiritual and moral culture by Yu.N. Sinitsyn; methodology for assessing the formation of vital functions, spiritual and moral development and destructive manifestations of a student by V.I. Andreev, Yu.N. Sinitsyn). The method of mathematical statistics is the Kramer-Welch T-test. Results. The analysis of the problem of preventing destructive behavior of students in the process of forming a spiritual and moral culture allowed us to develop and test a practice-oriented model of PDPO in the process of FDNA, which is based on objective and subjective pedagogical conditions, using integrative technology for preventing destructive behavior of students. As a result of the implementation: 1) a decrease in the level of destructive behavior of students by 60,7%, the effectiveness of experimental exposure is represented by changes in the difference in characteristics according to the coefficients ТEMP before = 0,009 and ТEMP after = 4,59; 2) an increase in the levels of vital functions by 12,1% (ТEMP before = 0,24, ТEMP after = 6,23), the formation of moral qualities in students by 13,2% (ТEMP before = 0,03, ТEMP after = 8,24), the readiness of students for PDPO in the FDNA process by 15,7% (ТEMP before = 0,45, ТEMP after = 8,15). Conclusion. The created practice-oriented model of PDPO in the process of FDNA allows to expand the understanding of the prevention of destructive behavior of students in the process of forming a spiritual and moral culture and can act as a prerequisite for: the development of network interaction of educational organizations in the systems of general and vocational education on this issue; the continuity of FDNA of students in educational organizations at all levels; conducting advanced training courses qualifications of teaching staff, parental training. Keywords: spiritual and moral culture, prevention of destructive behavior, students, conceptual model, pedagogical system, criteria and indicators of readiness for the prevention of destructive behavior, practical recommendations

Soybean rust, caused by the fungus Phakopsora pachyrhizi, is an economically important disease of soybean with potential to cause severe epidemics resulting in significant yield losses. Host resistance is one of the management tools to control this disease. This study compared soybean genotypes exhibiting immunity, complete and incomplete resistance, and susceptibility to an isolate of P. pachyrhizi based on visual assessment of reaction type, other visual traits such as sporulation, quantitative measurements of the amount of fungal DNA (FDNA) present in leaf tissues, and data on infection and colonization levels. Soybean genotype UG5 (immune), and plant introduction (PI) 567102B and PI 567104B (complete resistance) had lower quantities of uredinia and FDNA than four other genotypes with incomplete resistance. Based on microscopic observations, early events of spore germination, appressorium formation, and fungal penetration of the epidermis occurred within 24 h postinoculation and were similar among the tested soybean genotypes. Differences in infection among the genotypes were evident once the hyphae penetrated into the intercellular spaces between the mesophyll cells. At 2 days after inoculation (dai), soybean genotype Williams 82 had a significantly (P < 0.05) higher percentage of hyphae in the mesophyll tissue than other soybean genotypes, with UG5 having significantly (P < 0.05) lower percentages than all of the other soybean genotypes at 3, 4, and 5 dai. The percentage of interaction sites with mesophyll cell death was significantly (P < 0.05) higher in UG5 than other genotypes at 3, 4, and 5 dai. There was a significant positive correlation (r = 0.30, P < 0.001) between quantities of hyphae in the mesophyll cells and FDNA. These results demonstrated that incompatible soybean–P. pachyrhizi interaction results in restricted hyphal development in mesophyll cell tissue, likely due to hypersensitive apoptosis.

The aim of the present preliminary study was to investigate the presence of free DNA (FDNA) in urine as a possible marker for the diagnosis of bladder cancer. Naturally voided morning urine specimens were collected from 57 patients with suspected bladder cancer before cystoscopy. A standard urine test was performed; the specimens were then processed in order to obtain a quantitative evaluation of the presence of free DNA in the urine. Twenty-two patients were excluded from the study because they had leukocyturia and/or bacteriuria. Free DNA concentrations higher than 250 ng/mL were found in all 16 patients showing bladder cancer at cystoscopy and in seven (36.8%) of the 19 patients with negative cystoscopy. Urinary FDNA seems to have an excellent sensitivity: we observed no false negative cases and 36.8% false positive cases. By contrast, only 6.25% of the bladder cancer patients had positive urine cytology. Our results seem promising, although further studies and larger numbers are needed to define urinary free DNA as a reliable marker of bladder cancer.

Livestock farming is of great importance in brazilian exports. It is an economic activity developed in rural areas that consists of the cattle raising, characterized by the dependence on the use of pastures due to the lower cost of production. This requires a large, well-structured pasture area with good quality leaves and tillers to meet the requirements of the herd, thus making a good profitability. Currently, one of the forage species that is widely distributed in the country, is Urochloa brizantha (Syn. Brachiaria brizantha). Such occurrence is due to this grass, to have good adaptation to less fertile soils, of sandy texture and to tolerate high saturations of aluminum. However, in the areas used for cultivation of these pastures many are found to have some degree of degradation due to lack of maintenance, especially the lack of fertilization and irrigation. Proposing technologies that aid in the performance of these pastures and make their recovery become essential. Among alternatives to reduce the severity of these problems, the use of irrigation in summer periods may be a technique to be used, however there are regions in the country that water is scarce and thus this technique is invalid. Another option is the use of fertilizers, but it is a high-cost activity, with producers seeking more and more effective fertilizers. The use of organomineral fertilizers has been highlighted, due to the fact that it contains an organic part in its formulation and this, in turn, causes the release of nutrients to be slower, promoting lower losses, besides helping to retain water in the soil.

Abstract

This master thesis investigates several di®erent channel estimation techniques in an SC-

FDMA (Single Carrier Frequency Division Multiple Access) system with parameters set

according to the standards of 3GPP LTE (3rd Generation Partnership Project Long Term

Evolution). 3GPP LTE is the name given to a project within the 3GPP to improve the

mobile phone standard to cope with future requirements. In this thesis, we ¯rst introduce

the SC-FDMA system, which is a transmission technique that utilizes single carrier mod-

ulation, then ¯ve types of estimators are investigated. Essential to all channel estimatiors

is the use of pilot symbols. In the last part we compare the performance of the channel

estimation techniques with each other in di®erent environments by analysing their symbol

error rates. All simulations are done in a Matlab environment.

Conservation translocations are increasingly used worldwide to prevent extinctions and support ecological restoration projects. These translocations involve a lot of uncertainty, particularly when species are introduced to ecosystems where they have not previously coexisted. Many historical translocations in Australia and globally have failed due to insufficient baseline data and inadequate post-translocation monitoring. Contemporary translocations can aim to improve translocation outcomes by increasing baseline data collection and developing robust post-release monitoring for translocated species. The development of environmental DNA (eDNA) techniques has facilitated the collection of information from environments with minimal disturbance to species. The advancement of such passive monitoring techniques has allowed for increased ability to monitor and study cryptic and rare species. The Shark Bay rufous hare-wallaby (Lagorchestes hirsutus bernieri) and the banded hare-wallaby (Lagostrophus fasciatus) were introduced to Dirk Hartog Island (DHI) from founder populations on the Bernier and Dorre islands in Shark Bay, Western Australia, as part of the Dirk Hartog Island National Park Ecological Restoration Program. Once found across large areas of south-west and central Australia, the populations on the Bernier and Dorre islands are the last natural populations of the two species due to habitat loss and predation post-European colonisation. As the rufous hare-wallaby and banded hare-wallaby have not been previously recorded on DHI, there was uncertainty regarding their successful establishment on the island and their potential interactions with each other and other species involved in the restoration program. The diets of rufous hare-wallabies and banded hare-wallabies were investigated through the DNA metabarcoding of scat samples from three islands in Shark Bay, Western Australia. This researched aimed to assess dietary overlap and the potential for resource competition between the two hare-wallaby species. Additionally, the difference in diet between the founder populations to their post-translocation diets on DHI were analysed as an indication of dietary flexibility and adaptability to environmental changes. The diets of both species of hare-wallaby were found to be broad, containing taxa from multiple plant families including invasive weeds. On DHI there was a high degree of overlap in the diets of the two species, indicating a risk of resource competition. The diets of the translocated populations differed significantly from the founder populations, which demonstrated flexible foraging behaviour and signified that rufous hare-wallabies and banded hare-wallabies are excellent candidates for future translocation projects on other islands and within mainland reserves. This thesis is the first study to define and compare the diets of the Shark Bay rufous hare-wallaby and the banded hare-wallaby using scat DNA. The understanding of diet is fundamental to ecology and an essential consideration in restoration projects involving new species interactions. The findings from this research can benefit the fulfilment of translocation success criteria related to species establishment and health targets for the new populations. By demonstrating the dietary breadth and flexibility of Shark Bay’s hare-wallabies, this thesis exemplifies the utility of scat DNA in supporting the conservation of translocated fauna.

In this paper, a hybrid frequency division multiple access/code division multiple access (FDMA/CDMA) system in a Rician fading channel is described and analysis. The performance of the hybrid system is compared with a wideband CDMA system, which occupies the same total bandwidth. The results show that for DPSK modulation with a RIKE receiver, a hybrid system can have a greater capacity with a strong direct path component or a high signal to noise ratio (SNR). Otherwise, a wideband system remains optimal.

Mestrado em Engenharia Electrónica e Telecomunicações
Mobile traffic in cellular networks is increasing exponentially. Small-cells are considered as a key solution to meet these requirements. Under the same spectrum the small-cells and the associated macro-cell (forming the so called heterogeneous systems) must cooperate so that one system can adapt to the other. If no cooperation is considered then the small-cells will generate harmful interference at the macro-cell. Interference alignment (IA) is a precoding technique that is able to achieve the maximum degrees of freedom of the interference channel, and can efficiently deal with inter-systems interference. Single carrier frequency division multiple access (SC-FDMA) is a promising solution technique for high data rate uplink communications in future cellular systems. Conventional linear equalizers are not efficient to remove the residual inter-carrier interference of the SC-FDMA systems. For this reason, there has been significant interest in the design of nonlinear frequency domain equalizers in general and decision feedback equalizers in particular, with the iterative block decision feedback equalizer (IB-DFE) being the most promising nonlinear equalizer. In this dissertation we propose and evaluate joint interference alignment precoding at the small cell user terminals with iterative non-linear frequency domain equalizer at the receivers (macro base station and central unit) for SC-FDMA based heterogeneous networks. The small-cell precoders are designed by enforcing that all generated interference at the macro-cell is aligned in an orthogonal subspace to the macro-cell received signal subspace. This enforces that no performance degradation is observed at the macro cell. Then, we design an iterative nonlinear frequency domain equalizer at the macro-cell receiver that is able to recover the macro-cell spatial streams, in the presence of both small-cell and inter-carrier interferences. The results show that the proposed transmitter and receiver structures are robust to the inter-system interferences and at the same time are able to efficient separate the macro and small cells spatial streams.
O trafego móvel nas redes celulares tem aumentado exponencialmente. As pico- células são consideradas como a solução chave para cumprir estes requisitos. Dentro do mesmo espectro, as pico-células e as macro-células (formando os chamados sistemas heterogéneos) precisam de colaborar de modo a que um sistema possa adaptar-se ao outro. Se não for considerada a cooperação, então as pico-células irão gerar interferência prejudicial na macro-célula. Interference alignment (IA) é uma técnica de précodificação que é capaz de atingir o grau máximo de liberdade do canal de interferência, e consegue lidar eficazmente com interferência entre sistemas. Single carrier frequency division multiple access (SC-FDMA) é uma solução técnica promissora para transmissão de dados em uplink, para sistemas celulares futuros. Equalizadores lineares convencionais não são eficientes a remover a interferência residual entre portadoras dos sistemas SC-FDMA. Por este motivo, tem havido interesse significativo no desenho de equalizadores não lineares no domínio da frequência em geral e em equalizadores baseados em decisão por feedback em particular, tendo o iterative block decision feedback equalizer (IB-DFE) como o equalizador não linear mais promissor. Nesta dissertação propomos e avaliamos précodificação de alinhamento de interferência nos terminais das pico-células em conjunto com equalizadores não lineares no domínio da frequência nos recetores (estação base da macro-célula e unidade central de processamento) para redes heterogéneas baseadas em SC-FDMA. Os précodificadores das pico-células são desenhados de maneira a obrigar a que toda a interferência gerada na macro-célula esteja alinhada num subespaço ortogonal em relação ao subespaço do sinal recebido na macro- célula. Isto obriga a que não seja observada degradação de desempenho na macro-célula. Em seguida, desenhamos um equalizador não linear no domínio da frequência no recetor da macro-célula capaz de recuperar os fluxos de dados da macro-célula, na presença de interferência tanto entre portadoras como das pico-células. Os resultados mostram que as estruturas de transmissão e receção propostas são robustas contra a interferência entre sistemas e ao mesmo tempo capaz de separar eficientemente os dados da macro e das pico células.

Sagu (Maranta arundinacea), es una planta que se caracteriza por sus rizomas cilíndricos y tuberosos de los cuales se extrae almidón, sin embargo, poco se ha reportado sobre las bondades que pueden brindar sus hojas para la alimentación animal. Por tanto, el objetivo de esta investigación fue determinar la presencia o ausencia de metabolitos secundarios en hojas y rizomas de sagu y caracterizar la fibra de las hojas con el fin de determinar su valor nutricional. Se realizó a las hojas y rizomas de sagu, un análisis proximal (Materia seca (MS), proteína cruda (PC), extracto etéreo (EE), Cenizas, Fibra cruda (FC) y extracto libre de nitrógeno (ELN)), se empleó la tecnología ANKOM para determinar la fibra detergente neutra (FDN), fibra detergente ácida (FDA), lignina detergente ácida (LDA) y energía bruta (EB). Se verifico la ausencia de metabolitos secundarios en hojas y rizomas; las hojas presentaron alto contenido de PC 22.01% y el análisis Vas Soest realizado a las hojas determino una FDN de 57.13%, FDA 32.33% y lignina de 9.20% lo que indica que es un material de excelente calidad para la alimentación animal.

At the request of the Fire Department City of New York (FDNY), UL’s Fire Safety Research Institute (FSRI) instrumented and documented a series of 12 thermal exposure hose experiments that were conducted in the burn compartment of an FDNY flashover simulator. The main objective of the experiments was to observe the performance of fire hoses exposed to the heat flux from flaming hot gas layer conditions above the hose. FDNY collected a variety of hose types that represented a cross section of commercially available materials and construction methods. The thermal exposures generated in the burn compartment were measured. The fire experiments were stopped once the hose being examined began to lose water through the wall of the hose. All of the hoses lost water through their wall, although the size of the holes and the amount of water leakage varied. While the burn compartment provided a “fire room environment” and different types of hose failures were demonstrated, the thermal exposure within the compartment was not demonstrated to be repeatable. Therefore it is not possible to develop a comparable rank or rating of the fire resistance of these hoses from this series of experiments.

Systematic reviews often omit unpublished data due to time constraints, unclear data integration methodologies, and uncertainties about the value of including these data. This can lead to inflated efficacy estimates and underestimated harms or burdens, as unpublished studies often document negative efficacy outcomes and/or harms. This brief methods project demonstrated the integration of U.S. Food and Drug Administration (FDA) drug approval packages (i.e., FDA reviews) into three systematic reviews focusing on psychoactive drugs—paroxetine (Paxil®) for adults with post-traumatic stress disorder (PTSD), escitalopram for major depressive disorder (MDD) in adolescents, and aripiprazole for bipolar disorder in adults. We searched the FDA reviews and matched identified trials with those in the Agency for Healthcare Research and Quality’s Effective Health Care Program systematic reviews. Then, we conducted meta-analyses combining unpublished and published studies. Our analysis identified important discrepancies in effect sizes, with meta-analyses of both published and unpublished data for paroxetine showing smaller effect sizes than those using only published trials. Our findings suggest a potential overestimation of paroxetine efficacy in published literature. Incorporating FDA reviews could enhance the accuracy of effect estimates in systematic reviews. However, using unpublished data requires careful consideration due to the intensive resources required. Future research should expand to other therapeutic areas and include more sources of unpublished data to increase the robustness of systematic reviews.
