Abstract:
Background: The imaging and analysis of the ciliary body (CB) are valuable in many potential clinical applications. This study aims to demonstrate the anatomy characteristics of CB using radial and transverse imaging of ultrasound biometric microscopy (UBM) in healthy Chinese subjects, and to explore the determining factors. Methods: Fifty-four eyes of 30 healthy Chinese subjects were evaluated. Clinical data, including age, body mass index (BMI), intraocular pressure (IOP), axial length (AL), and lens thickness (LT), were collected. Radial and transverse UBM measurements of the ciliary body were performed. Anterior chamber depth (ACD), ciliary sulcus diameter (CSD), ciliary process length (CPL), ciliary process density (CPD), ciliary process area (CPA), ciliary muscle area (CMA), ciliary body area (CBA), ciliary body thickness (CBT0, CBT1, and CBTmax), anterior placement of ciliary body (APCB), and trabecular-ciliary angle (TCA) of four (superior, nasal, inferior, and temporal) quadrants were measured. Results: The average CPL was 0.513 ± 0.074 mm, and the average CPA was 0.890 ± 0.141 mm2. CPL and CPA tended to be longer and larger in the superior quadrant (p < 0.001) than in the other three quadrants. Average CPL was significantly correlated with AL (r = 0.535, p < 0.001), ACD (r = 0.511, p < 0.001), and LT (r = −0.512, p < 0.001). Intraclass correlation coefficient (ICC) scores were high for CPL (0.979), CPD (0.992), CPA (0.966), CMA (0.963), and CBA (0.951). Conclusions: In healthy Chinese subjects, CPL was greatest in the superior quadrant, followed by the inferior, temporal, and nasal quadrants, and CPA was largest in the superior quadrant, followed by the tempdoral, inferior, and nasal quadrants. Transverse UBM images can be used to measure the anatomy of the ciliary process with relatively good repeatability and reliability.

Abstract:
The incidence of chronic pulmonary aspergillosis (CPA) is especially increasing in high tuberculosis (TB) burden countries. Despite a high estimated CPA burden in Pakistan, actual data on CPA are not available. The aim of the current study is to determine the underlying conditions and clinical spectrum of CPA at a tertiary care hospital in Karachi, Pakistan. This is a retrospective chart review study in patients admitted with CPA from January 2012 to December 2017. A total of 67 patients were identified during the study period. Mean age of CPA patients was 45.9 ± 15 years, 44 (65.7%) were male and 19 (28.4%) had diabetes. The most common type of CPA was simple aspergilloma (49.2%) followed by chronic cavitary pulmonary aspergillosis (CCPA) (44.7%). TB was the underlying cause of CPA in 58 (86.6%) patients followed by bronchiectasis caused by allergic bronchopulmonary aspergillosis (ABPA) 8 (11.9%). Aspergillus flavus was identified in 17 (47.2%), followed by A. fumigatus in 13 (36.1%) CPA patients. Isolation of multiple Aspergillus species was found in 10 (25.6%) patients. Itraconazole was given in 27 (40.3%) patients and a combination therapy of itraconazole and surgery was given in 21 (31.34%) patients. We found aspergilloma and CCPA as the most prevalent forms of CPA in our setting. Further large prospective studies using Aspergillus specific immunoglobulin G (IgG) antibodies testing are required for better understanding of CPA in Pakistan.

Abstract:
Objective. Electroacupuncture (EA) is reported effective in alleviating pain-related emotion; however, the underlying mechanism of its effects still needs to be elucidated. The NPS-NPSR system has been validated for the involvement in the modulation of analgesia and emotional behavior. Here, we aimed to investigate the role of the NPS-NPSR system in the anterior cingulate cortex (ACC), hypothalamus, and central amygdala (CeA) in the use of EA to relieve affective pain modeled by complete Freund’s adjuvant- (CFA-) evoked conditioned place aversion (C-CPA). Materials and Methods. CFA injection combined with a CPA paradigm was introduced to establish the C-CPA model, and the elevated O-maze (EOM) was used to test the behavioral changes after model establishment. We further explored the expression of NPS and NPSR at the protein and gene levels in the brain regions of interest by immunofluorescence staining and quantitative real-time PCR. Results. We observed that EA stimulation delivered to the bilateral Zusanli (ST36) and Kunlun (BL60) acupoints remarkably inhibited sensory pain, pain-evoked place aversion, and anxiety-like behavior. The current study showed that EA significantly enhanced the protein expression of this peptide system in the ACC and hypothalamus, while the elevated expression of NPSR protein alone was just confined to the affected side in the CeA. Moreover, EA remarkably upregulated the mRNA expression of NPS in CeA, ACC, and hypothalamus and NPSR mRNA in the hypothalamus and CeA. Conclusions. These data suggest the effectiveness of EA in alleviating affective pain, and these benefits may at least partially be attributable to the upregulation of the NPS-NPSR system in the ACC and hypothalamus.

Abstract:
Objectives: Aspergillus-specific IgG (Asp-IgG) cut-off level in diagnosing chronic pulmonary aspergillosis (CPA) remains unknown. Methods: We prospectively recruited participants with clinical suspicion of CPA in three centers in Taiwan during 2019 June to 2020 August. Serum Aspergillus fumigatus-specific IgG (Asp-IgG) (Phadia, Uppsala, UPPS, Sweden) was examined. Optimal cut-off level was determined by Youden’s index and validated. Results: A total of 373 participants were recruited. In the derivation cohort (n = 262), Asp-IgG had an area under the receiver-operating-characteristic curve (AUC) of 0.832. The optimal cut-off level was 40.5 mgA/L. While applying this cut-off level to the validation cohort (n = 111), the sensitivity and specificity were 86.7% and 80.2%. Lowering the cut-off level from 40.5 to 27 mgA/L, the sensitivity was steady (30/36, 83.3% to 31/36, 86.1%) while specificity dropped from 81.9% (276/337) to 63.5% (214/337). Restricting CPA diagnosis to only chronic cavitary pulmonary aspergillosis (CCPA) and chronic fibrosing pulmonary aspergillosis (CFPA) yielded a cut-off level of 42.3 mgA/L in the derivation cohort with a sensitivity of 100% and specificity of 84.4% in the validation cohort. Conclusions: Serum Asp-IgG performs well for CPA diagnosis and provides a low false-positive rate when using a higher cut-off level (preferably around 40 mgA/L).

Abstract:
Summary Objective The aim of this study was to investigate the toxic effect of cyclophosphamide (CPA) in the development of rodent molars. Methods CPA was administered intraperitoneally in postnatal mice between Day 1 and Day 10, and the morphological phenotype was evaluated at Day 26 using micro-computed tomography and histological analysis, including cell proliferation and cell death analyses. Results M3 molars of the mice who received 100 mg/kg CPA treatment at Day 6 or M2 molars who received treatment at Day 1 resulted in tooth agenesis or marked hypoplasia. Histological observation demonstrated that CPA treatment at Day 6 resulted in shrinkage of the M3 tooth germs, with a significant reduction in the proliferation of apoptotic cells. Conversely, CPA exposure at Day 2, which occurs at around the bud stage of M3, resulted in crown and root hypoplasia, with reduced numbers of cusp and root. In addition, CPA exposure at Day 10, which is the late bell stage of M3, induced root shortening; however, it did not affect crown morphogenesis. Limitations The timing of CPA administration is limited to after birth. Therefore, its effect during the early stages of M1 and M2 could not be investigated. Conclusion Defective phenotypes were evident in both crown and roots due to the effect of CPA. Interestingly, the severity of the phenotypes was associated with the developmental stages of the tooth germs at the time of CPA administration. The cap/early bell stage is the most susceptive timing for tooth agenesis, whereas the late bell stage is predominantly affected in terms of root formation by CPA administration.

Abstract:
Chronic pulmonary aspergillosis (CPA) complicating sarcoidosis (SA) is associated with high mortality, and there is a lack of clarity regarding the relative contributions of SA or CPA.This was a retrospective single-centre study on CPA-SA.In total, 65 patients (44 men), aged 41.4±13.5 and 48.3±11.9 years at the time of SA and CPA diagnoses, respectively, were included between 1980 and 2015. Of these, 64 had fibrocystic SA, most often advanced, with composite physiological index (CPI) >40 (65% of patients) and pulmonary hypertension (PH) (31%), and 41 patients (63%) were treated for SA (corticosteroids or immunosuppressive drugs). Chronic cavitary pulmonary aspergillosis (CCPA) was the most frequent CPA pattern. Regarding treatment, 55 patients required long-term antifungals, 14 interventional radiology, 11 resection surgery and two transplantation. Nearly half of the patients (27; 41.5%) died (mean age 55.8 years); 73% of the patients achieved 5-year survival and 61% 10-year survival. Death most often resulted from advanced SA and rarely from haemoptysis. CPI, fibrosis extent and PH predicted survival. Comparison with paired healthy controls without CPA did not show any difference in survival, but a higher percentage of patients had high-risk mould exposure.CPA occurs in advanced pulmonary SA. CPA-SA is associated with high mortality due to the underlying advanced SA rather than to the CPA. CPI, fibrosis extent and PH best predict outcome.

Abstract:
This paper reports on the volatile components of oils from the aerial parts (CBA) and roots (CBR) of Centaurea bracteata Scop. and aerial parts of C. pannonica (Heuffel) Simonkai subsp. pannonica (CPA), two Asteraceae growing wild in Croatia. The volatile components, obtained by hydrodistillation, were determined by GC-MS analysis. The yields (w/w) of the dried oils were 0.10% (CBA), 0.22% (CBR) and 0.09% (CPA), respectively. A total of 91 compounds were identified accounting for 91.1%, 93.3% and 87.9% of the total oil for CBA, CBR and CPA, respectively. All the samples were characterized mainly by hydrocarbons (7.1-34.1%), fatty acids (9.7-45.9%), and oxygenated sesquiterpenes (15.2-16.6%). The major components of the samples were hexadecanoic acid (8.1-31.1%), nonacosane (0.6-13.4%) and caryophyllene oxide (4.5-11.9%). Monoterpenes, both hydrocarbons and oxygenated, were either absent or present in low amounts in all the oils. The similarity in the oil contents is consistent with the two species being placed in the same section, Jacea.

Resumo:Devido a redução nos custos dos processadores, causada pela evolução tecnológica, ocorreu uma revolução nos sistemas de controle e de processamento. Os sistemas de controle que tradicionalmente eram quase que exclusivamente centralizados, passaram a ser preteridos em função dos sistemas distribuídos. Os sistemas distribuídos propiciam uma capacidade de processamento ampliável, teoricamente infinita, pela agregação de novas unidades de processamento, além de prover um nível de confiabilidade superior ao dos sistemas centralizados convencionais. O propósito desta tese é descrever a arquitetura e a implementação de uma rede local de processadores particular que caracteriza um sistema distribuído. O objetivo imediato deste desenvolvimento foi servir como suporte ao controle de uma central CPA-T (central temporal com controle por programa armazenado) de grande porte (Sistema TRÓPICO RA). Como resultado obteve-se uma estrutura de controle que atendeu a todos os requisitos especificados. Além disso, a sua flexibilidade é tal que a mesma solução permite ser utilizada em outras aplicações onde seja necessário um sistema de comunicação entre processadores com características como alta performance, modularidade, confiabilidade, com a vantagem de utilizar-se um reduzido número de componentes de fácil aquisição no mercado

Mestrado em Engenharia Química
As emissões de dióxido de carbono têm hoje uma grande importância na indústria de engenharia química, pelo que a sua captura e armazenamento são uma importante área de investigação. Os líquidos iónicos têm sido estudados como solventes (“green solvents”) para a separação de gases e captura de dióxido de carbono. Os líquidos iónicos são uma nova classe de solventes orgânicos, que devido aos seus catiões orgânicos assimétricos e aos aniões inorgânicos, não podem constituir uma estrutura cristalina, permanecendo assim no estado líquido à temperatura ambiente ou temperaturas próximas desta. Estes compostos apresentam uma vasta gama de propriedades interessantes, tais como a alta estabilidade térmica; o estado líquido numa grande amplitude térmica; a boa solvatação, tanto para compostos polares como não polares; e uma das mais interessantes, colocando-os como uma alternativa viável para substituir os solventes orgânicos voláteis, a sua pressão de vapor desprezável. Outra grande vantagem destes solventes "neotéricos" é a possibilidade de modelar as suas propriedades, através da infinita combinação de catiões e aniões, permitindo desenhar os líquidos iónicos de acordo com os objectivos específicos de uma operação particular melhorando o seu desempenho. Já foram aplicadas várias equações de estado para descrever a solubilidade do dióxido de carbono nos líquidos iónicos (equilíbrio líquidovapor), tais como a PC-SAFT, soft-SAFT, Peng-Robinson, Krichevsky- Kasarnovsky, entre outras equações de estado. Neste trabalho, dados experimentais para o equilíbrio líquido-vapor do sistema de dióxido de carbono + 1-alquil-3-metilimidazólio bis(trifluorometilsulfonil)imida foram modelados pela primeira vez com a equação do estado Cubic Plus Association (CPA EoS), em que os parâmetros da equação são obtidos através do ajuste de dados experimentais de pressão de vapor e densidade. Com o objectivo de estudar a solubilidade do dióxido de carbono noutros compostos, foram também medidos os equilíbrios líquidovapor dos sistemas dióxido de carbono + dissulfureto de carbono e dióxido de carbono + tetraclorometano, numa célula de alta pressão, e os dados experimentais obtidos foram igualmente modelados com a CPA EoS. A equação de estado CPA já demonstrou ser uma ferramenta termodinamicamente flexível tendo descrito correctamente o equilíbrio líquidovapor de misturas contendo componentes associativos e não associativos distribuídos por diferentes fases fluidas. Mostra-se que este modelo permite uma boa descrição dos dados experimentais disponíveis. ABSTRACT: Carbon dioxide emissions have today a great importance in the chemical engineering industry, so its capture and storage are an important field of research. Ionic liquids have been studied as green solvents in gases separation and for carbon dioxide capture. Ionic liquids are a new class of organic solvents that due to their asymmetric organic cations and organic or inorganic anions cannot form an ordered crystal and therefore remain liquid at or near room temperature. These compounds present a wide range of interesting properties, such as high thermal stability, large liquid temperature range, good solvation both for polar and non polar compounds, and one of the most interesting, putting them as a viable and ambient friendly alternative to replace the volatile organic solvents, is their negligible vapor pressure. Other major advantage of these “neoteric” solvents is the possibility of fine tune their properties through the endless combination of cations and anions. This designer characteristic allows one to build task-specific ionic liquids that have an enhanced performance for specific operations. Several equations of state have been applied to describe the carbon dioxide solubility in ionic liquids (vapor-liquid equilibrium) such PC-SAFT, soft- SAFT, Peng-Robinson EoS, Krichevsky–Kasarnovsky EoS, among others. In this work, the experimental vapour-liquid equilibrium data of the systems carbon dioxide + 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquids were modelled for the first time with the Cubic plus Association Equation of State (CPA EoS) with the EOS parameters fitted to vapor pressure and densities of the ionic liquids. In addition, it was used a high pressure cell to measure the vapour-liquid equilibrium of the binary systems carbon dioxide + carbon disulphide and carbon dioxide + carbon tetrachloride and the experimental data obtained were also modelled with the CPA EoS. The CPA EoS had already demonstrated to be a flexible thermodynamic tool for correctly modelling the phase equilibrium of mixtures containing both associative and non-associative components distributed by different fluid phases. It is shown that this model allows for a very good description of the experimental data available.

Abstract:
Ces dernières années, le développement des lasers femtosecondes s’est massivement orienté vers des sources à fortepuissance moyenne pour des applications autant scientifiques - par exemple la génération d’impulsions XUV - qu’industrielles. Cettethèse a consisté à développer une source laser permettant d’amplifier des impulsions ultra-brèves à très haute cadence par un laserà fibre avec d’un côté le développement d’un laser de pompe femtoseconde fibré (<600fs) à haute cadence (100kHz), et de fortepuissance (50W) et de l’autre des amplificateurs paramétriques optiques ultrabrefs (<10fs) pompés par cette même source. Pour cela,au sein d’une architecture à dérive de fréquence de fort étirement (2ns), nous avons exploité les propriétés des fibres photoniques à trèsgros coeur dopé à l’Ytterbium qui, pour approcher des énergies proches de 1mJ, nécessitent d’effectuer des études d’endommagement etde préparation des fibres. Nous avons alors pu démontrer une puissance maximale de 90W mais d’excellents résultats ont été établis dansun régime stable et robuste pour lequel ce laser délivre une puissance de 60W avec des impulsions de durées inférieures à 400fs. Aprèsdoublage en fréquence, ce laser a permis alors d’amplifier en deux étages dans des cristaux de BBO des bandes spectrales supérieuresà 300nm centrées autour de 800 nm avec une énergie par impulsion de 19[mu] J (1.9W). Avec un système d’étirement et de compressionbasé sur la combinaison de lames de silice et de miroirs à dérive de fréquence, ces impulsions ont pu atteindre une durée finale de 9.7fs.Ainsi, ces deux sources permettent d’ouvrir la voie à de vastes champs d’investigation en physique moléculaire et atomique
In recent years, the development of femtosecond lasers has been heavily oriented towards high average power sources forboth scientific experiments - such as XUV pulses generation - as well as for industrial applications. This work has been devoted to developa laser source able to amplify ultra-short pulses at a very high repetition rate. In one hand, we develop a high average power (50W)pump laser based on a Fiber Chirped Pulse Amplification (FCPA) technology delivering 400 fs pulses at a high repetition rate (100kHz).In the other hand, a multistage ultrafast optical parametric amplifiers (<10fs) pumped by this source has been then implemented. Toachieve this, we took the benefits of the Ytterbium-doped large-core photonics fibre’s properties in order to approach energies closeto 1mJ. Even in a highly stretched chirped pulse architecture (2ns), using this kind of technology, required to perform studies overdamage and preparation processes of fibers. Thereby, we demonstrated a maximum output power of 90W, but excellent results havebeen obtained in a stable and robust regime in which this laser delivers 60W with pulse durations shorter than 400fs. After frequencydoubling, this laser was sent as a pump into a two-stages - non collinear parametric amplifier made with BBO crystals and a spectrumdelivered a by a CEP-Stable-6fs Ti :sa oscillator has been amplified around 800nm over a spectral bandwidth larger than 300nm witha pulse energy of 19[mu] J (1.9W). By using a stretching and compression scheme based on the combination of silica wedges and chirpedmirrors, the final pulses have been then recompressed down to 9.7fs. These laser systems can be now used to pave the way for vast fieldsof investigation in molecular and atomic physics

Abstract:
The research investigated the factors that are associated with organisational performance in British local public services using the national assessment frameworks of Comprehensive Performance Assessment (CPA) and Comprehensive Area Assessment (CAA). Performance measurement was said by Behn (1995) to be one of the big questions of public management and the literature demonstrates this remains the case. More generally performance management has been the subject of a large number of studies, many in the private sector, that often consider a narrow spectrum of explanatory factors. This research is unusual in studying a relatively large number of possible explanations of performance using three different methods of inquiry: longitudinal questionnaire surveys of four types of local public service organisations, a content analysis of strategic documents and the use of organisational profiles regarding the post bureaucratic construct (Kernaghan, 2000). The research relied on the CPA and CAA results to provide an independent assessment of organisational performance; such data is not usually available for public services. CPA has been found to have driven up local government performance (Boyne, James and John et al, 2010) and therefore its use is very appropriate. The analysis used correlation to identify the significant (p<0.05) criteria which were then put through a principal component analysis (PCA). This resulted in the identification of 11 summary factors with the strongest five being Strategy, Performance management, Human resources, Culture and Engagement. Factors of lesser importance are Resources, Leadership, Reputation and Innovation. The term ‘summary factors’ has been used to denote that within each of these there are potentially a number of parts. The research can be used practically by organisations, to improve, by comparing their results on the questionnaire with the criteria associated with high organisational performance. Further, the summary factors provide confidence regarding what may be the most critical areas to be addressed.

Os hidrocarbonetos aromáticos policíclicos (PAHs) constituem uma família de compostos caracterizada por possuírem dois ou mais anéis aromáticos condensados. São no geral referenciados de contaminantes ambientais porque estão associados à combustão incompleta de materiais orgânicos, como por exemplo, a queima de combustíveis fosseis, incineração de resíduos e derrames de petróleo. O estudo da solubilidade destes compostos em misturas aquosas é de grande importância, devido ao impacto que estes compostos têm na saúde pública e no meio ambiente, dado as suas propriedades cancerígenas. Neste trabalho, a capacidade da equação de estado CPA para modelar a solubilidade em meio aquoso de vários PAHs numa ampla gama de temperatura, foi avaliada. Esta equação de estado combina o termo Soave-Redlich-Kwong (SRK) para descrever as interações físicas com a contribuição de associação proposta por Wertheim, também usada em outras equações de estado, tais como as diferentes versões da SAFT. A CPA EoS já foi aplicada com sucesso a sistemas aquosos com alcanos, compostos aromáticos e álcoois. Os resultados obtidos são muito próximos dos valores encontrados na literatura, sugerindo que a CPA EoS é um modelo adequado para correlacionar soluções aquosas de moléculas complexas de poluentes orgânicos. ABSTRACT: The polycyclic aromatic hydrocarbons (PAHs) are a family of compounds characterized by having two or more aromatic rings condensed. They are referenced in general because they are environmental contaminants associated with the incomplete combustion of organic materials, such as the burning of fossil fuels and incineration of waste, and oil spills. The solubility of these xenobiotics in aqueous mixtures must be monitored due to their impact on public health and the environment, because of their carcinogenic properties and their ubiquity in the environment. In this work, the ability of the Cubic-plus-Association equation of state (CPA EoS) for modelling the aqueous solubility of several PAHs in a wide temperature range was evaluated. This equation of state combines the Soave-Redlich-Kwong (SRK) EoS for describing the physical interactions with the association contribution proposed by Wertheim, also used in other associating equations of state, such as the different versions of SAFT. The CPA EoS had already been successfully applied to aqueous systems with alkanes, aromatics and alcohols. The results obtained are in very close agreement with the literature data, suggesting that the CPA EoS is an adequate model for correlating aqueous solutions of complex molecules of organic pollutants.

Abstract:
Accounting professors will now be accountable for teaching their students to think critically, analyze, and evaluate information. The pressure to change accounting higher education cannot be ignored with the new version of the CPA exam, released in April 2017, which now tests analysis and evaluation skills. Have the professors made the changes in their classrooms that will help their students to be successful with this format of questioning? This research seeks to find whether professors have indeed embraced pedagogy that will enhance students’ ability to develop higher order thinking skills. The study begins by explaining changes to the CPA exam. The study provides literature review of the accounting education process, traditional methods of teaching accounting, suggested methods of teaching accounting for enhancement of critical thinking, and identified reasons for resistance to changing teaching methods. The survey is designed to identify current teaching methods in accounting classrooms. The survey seeks to discover what methods are being used to develop higher order thinking skills. The results show that lecture and demonstration of problems are still the predominant method of instruction in accounting classrooms, and these methods are not typically endorsed by research in terms of developing critical thinking, analysis and evaluation skills.

Full text
Abstract:
One of the most challenging issues in cryopreservation is to identify new and improved cryoprotective agents (CPAs) or CPA mixtures beyond widely used dimethyl sulfoxide (DMSO). In order to address this challenge, numerous combinations of CPA mixtures need to be prepared, characterized, and screened. The characterization includes thermal properties and phase change behavior during freezing and thawing. For an example, Han et al. [1] performed analysis of the phase change behavior and the thermal properties of phosphate buffers saline (PBS) with various chemical additives (CPAs, AFPs, excess salts) using a differential scanning calorimeter and a cryo-microscope. Considering the number of possible compositions and concentration of CPA mixtures, a high throughput (HTP) screening platform capable of preparing and characterizing array of CPA mixtures is highly desired.

Full text
Abstract:
In cell/tissue cryopreservation, cryoprotective agents (CPAs) should be added before freezing and removed after thawing. Nowadays people mainly apply centrifugation for CPA removal, which may cause many problems. Meanwhile, a simple and cheap method for real-time monitoring of the residual CPA concentration during processing remains an unfilled need. In this work, a “dilution-filtration” system with hollow fiber dialyzer was implemented and approved to remove dimethyl sulfoxide (Me2SO) effectively. Compared to other methods (centrifugation and microfluidic approach), this one holds advantages of low time and labor consumption, low osmotic injury to the cells, high effectiveness, ease to control the final suspension volume and low risk of contamination. The “dilution-filtration” system can also be easily modified for CPA addition and cell suspension volume control (concentration or dilution of cell suspension). Meanwhile, a method of electrical conductivity (EC) measurement was applied to monitor the residual CPA concentration. The results showed EC measurements of waste solution can convey the CPA concentrations in cell suspension. This validates the feasibility of a safer and easier way to on-line and real-time monitoring of CPA concentration in cell suspension by measuring the EC of waste solution.

Full text
Abstract:
Cryopreservation is the only alternative for long-term preservation of high-quality biomaterials, where the availability of reliable techniques for preservation of multicellular structures and organs represents an unmet medical need. Developing cryopreservation techniques revolves around controlling the formation of ice crystals, which is known to be lethal to living cells. Cryopreservation is typically achieved in the presence of cryoprotective agents (CPAs), which exhibit a dramatic increase in viscosity with decreasing temperature. Subject to high cooling rates, the rapidly elevating viscosity of the CPA suppresses ice crystallization and promotes vitrification (vitreous means glassy in Latin). Unfortunately, available CPAs are known to be toxic at the relevant concentrations which permit vitrification. One potential method of reducing CPA concentration, and thereby achieving conditions more favorable to the tissue, is with the introduction of the so-called synthetic ice blockers (SIBs)—the subject matter of the current study.

Abstract:
The objectives of the project were to develop a successful protocol for cryopreservation of penaeid germ plasm in order to preserve a pathogen-free broodstock nucleus for commercial exploitation of marine shrimp in aquaculture. The critical parameters to be characterized in the project were: 1. Determination of chill sensitivity and chill tolerant embryonic stages, including a full description and time course study of embryonic developmental stages. 2. Development of protocols for loading and removal of cryoprotectant agents (CPAs) from embryos; determination of optimal concentrations and duration of loading. 3. Characterization of the toxicity of the selected CP As and 4. Establishing optimal cooling and thawing procedures. Studies were performed on two penaeid species: Litopenaeus vannamei (in the USA) and P. semisulcatus (in Israel). The effect of incubation temperature on embryonic development rate and hatching success was studied in L. vannamei, showing that spawns maybe maintained at temperatures ranging from 24°C to 30°C, without compromising hatchability. Embryonic development extends from 12 hr to 19 hr at 30°C and 24°C, respectively. Studies showed that advanced embryonic developmental stages were chill tolerant in the two studied species, but P. semisulcatus could better endure lower temperatures than L. vannamei. A large number of experiments were performed to determine the optimal CP As, their concentration and duration of loading. Permeating (e.g. glycerol, methanol, DMSO, 1,2- propanediol, ethylene glycol, glucose) and non-permeating CPAs (sucrose, PVP, polyethylene glycol) were tested and several combinations of permeating and non-permeating CP As, on fertilized eggs (embryos), nauplii and protozoeae. In general, nauplii tolerated higher CPA concentrations than eggs and nauplii were also more permeable to radiolabeled methanol. Chlorine treatment intended to remove the chitinous envelop from eggs, did not increase dramatically the permeation of radiolabled methanol into eggs. Cooling eggs, nauplii or protozoeae to cryogenic temperatures, by either vitrification or slow cooling protocols, did not result in full survival of thawed samples, despite exhaustive attempts testing various protocols and CP As. Results seemed more encouraging in freezing of nauplii in comparison to eggs or protozoeae. Successful preliminary results in cryopreservation of spermatozoa of P. vannamei, will facilitate preservation of genetic specific to some extent.

Full text
Abstract:
The post-liberation peacebuilding in South Sudan, which largely drew from liberal peace theory, was employed between 2005 (after the signing of the Comprehensive Peace Agreement (CPA) and before the referendum, secession, and independence in 2011) and December 2013 (when it imploded into a civil conflict) and proved insufficient to sustain the fragile peace that briefly existed after the country’s secession from Sudan. After a protracted conflict lasting almost half a decade and the presence of multiple peace actors, the lack of a comprehensive and coordinated peacebuilding strategy proved detrimental. This failure is partly due to poor coordination between stakeholders and lack of local/domestic legitimacy, leading to insufficient peacebuilding and an aggravation of the 2013 conflict. Over the years, liberal peacebuilding strategies, which emphasize formal institution-building and statebuilding in fragile and conflict-affected environments, continue to produce mixed to poor results and fragile peace. This decline has resulted in the shifting of discourses and operations within peacebuilding, a paradigm shift that pays greater attention to localization and the local context in the conceptualization of peacebuilding objectives and strategies. This transformation promotes local ownership and inclusivity in peace processes and their dividends. The dialogue on inclusive peace has thus gained momentum, bearing a need to fully engage both states and societies in this process. The “local” in peacebuilding forms an important resource when solving root causes of conflicts, as in South Sudan, by improving awareness of the cultural and historical diversity in a given context.

Abstract:
Monilinia fructicola causes brown rot blossom blight and fruit rot in stone fruits. Immature fruit are highly resistant to brown rot but can become infected. These infections typically remain superficial and quiescent until they become active upon maturation of the fruit. High levels of chlorogenic acid (CGA) and related compounds occur in the peel of immature fruit but these levels decline during ripening. CGA inhibits cutinase expression, a putative virulence factor, with little or no effect on spore germination or hyphal growth. To better understand the regulation of cutinase expression by fruit phenolics, we examined the effect of CGA, caffeic acid (CA) and related compounds on the redox potential of the growth medium and intracellular glutathione (GSH) levels. The presence of CA in the medium initially lowered the electrochemical redox potential of the medium, increased GSH levels and inhibited cutinase expression. Conidia germinated in the presence of CA, CGA, or GSH produced fewer appressoria and had elongated germ tubes compared to the controls. These results suggest that host redox compounds can regulate fungal infectivity. In order to genetically manipulate this fungus, a transformation system using Agrobacterium was developed. The binary transformation vector, pPTGFPH, was constructed from the plasmid pCT74, carrying green fluorescent protein (GFP) driven by the ToxA promoter of Pyrenophora tritici-repentis and hygromycin B phosphotransferase (hph) under control of the trpC promoter of from Aspergillus nidulans, and the binary vector pCB403.2, carrying neomycin phosphotransferase (nptII) between the T-DNA borders. Macroconidia of M. fructicola were coincubated with A. tumefaciens strain LBA 4404(pPTGFPH) on media containing acetosyringone for two days. Hygromycin- and G418-resistant M. fructicola transformants were selected while inhibiting A. tumefaciens with cefotaxime. Transformants expressing GFP fluoresced brightly, and were formed with high efficiency and frequency of T-DNA integration frequency. The use of these transformants for in situ studies on stone fruit tissues is discussed.
