Повний текст джерелаThe complexity of biopharmaceutical products implies that their approval is based on a specific process. Any further change, especially in the process, requires drug validation in terms of clinical effects and biosecurity. Because changes in the processes may be unavoidable, quality assurance by inspection at the end of the process (Quality by Testing-QbT) tends to be replaced by a new quality perspective called Quality by design (QbD) which builds drug Critical Quality Attributes (CQA) controlling key Critical Process Parameters (CPP) in real-time. However, QbD implementation has been limited by the complexity of cell culture processes and the need for multivariate methods that allow the use of complex signals from process analyzers as monitoring instruments. Consequently, the objective of this work has been to develop new methodological and experimental applications, based on in situ NIR spectroscopy, for real-time monitoring of biopharmaceutical-producing cell cultures using two production platforms: animal cells (CHO-250-9) producing monoclonal antibodies (mAb) and plant cells (Cantharanthus roseus) producing antineoplastic molecules (vincristine-VC and vinblastine-VB). First, a process capable of producing VC and VB was generated, cell differentiation was identified as CPP and the ability to monitor it by in situ NIR spectroscopy was firstly demonstrated using calibration models based on partial least squares regression (PLSR). Subsequently in CHO cell cultures, different regression techniques were evaluated to generate calibration models to monitor CPP and CQA. PLSR was inadequate because of the chemical and physical variability that CHO cell cultures present during the different phases of batch culture. Local Weighted Regression (LWR) was adequate to monitor classic CPP (concentration of glucose, lactate, and viable cells, amongst others) since it adequately handled the variability associated with the progression of cell culture. However, for the glycosylation profile (CQA), it was unable to properly handle the complex nonlinear relationships between NIR spectra and the concentration of various monoclonal antibody (mAb) glycoforms. This was overcome with the use of models based on support vector regressions (SVR), allowing the generation of models of different mAb glycoforms related to particular clinical effects. Globally, this work has contributed to the expansion of the capabilities of in situ NIR spectroscopy for the monitoring of classic CPP in a more precise way, new innovative CPP such as cell physiological state in plant suspension cultures, and CQA such as mAb glycosylation profiles linked to clinical characteristics in animal cell cultures

ENGLISH ABSTRACT: Plums with good taste, aroma and eating quality lead to repeat purchases and sustained demand. Taste includes non-volatile compounds, e.g. sugars and acids, and has been well researched to meet the consumers’ preferences. Plum aroma, however, has not enjoyed the same attention. Limited literature is available on the aroma of Japanese plums and none could be found on the effects of relatively long cold storage on the profiles. The main aim of this study is to investigate the changes in aroma compounds of Japanese plums throughout maturation and ripening and the effects of commercial cold storage regimes. Near infra-red (NIR) spectroscopy was also evaluated as a non-destructive method to determine plum quality parameters aimed at minimising sample variability. In Paper 1, NIR spectroscopy was used to develop prediction models for total soluble solid (TSS), total acidity (TA), sugar-to-acid ratio, firmness and weight in three cultivars (Pioneer, Laetitia and Angeleno) and a multi-cultivar model. Samples were collected for seven consecutive weeks and repeated over two seasons. TSS results showed excellent predictability (R2 = 0.817-0.955; RMSEP= 0.453-0.610 % Brix) but the TA models did not perform well. The sugar-to-acid ratio models had results comparable to that of TSS. Both the firmness and weight models had acceptable results. The models of ‘Pioneer’ and ‘Laetitia’ had a better predictability capacity than the ‘Angeleno’ model. Although the multi-cultivar models outperformed the single cultivar models on R2 values it had higher prediction errors. The robustness of all the TSS, TA and firmness models is high in terms of seasonality, range and cultivar. Papers 2 and 3, the main focus of the study, are concerned with the aroma profile dynamics of Japanese plums. HS-SPME was used in both papers to extract the aroma compounds followed by GC-TOFMS for separation and identification. In Paper 2, the aroma volatile compounds of three cultivars (Pioneer, Laetitia and Angeleno) were determined for a seven week period including samples from three maturity stages (immature, harvest and tree-ripe). A total of 35 compounds were identified of which ten were generic. Each cultivar had five unique compounds resulting in different aroma profiles for each of the maturity stages and distinct separation patterns using discriminant analysis. The study was extended in Paper 3 where the aroma volatile compounds of six cultivars (Pioneer, Sapphire, Laetitia, Songold, Larry Anne and Angeleno) and one plumcot (Flavor King) were determined at three functional stages (commercial harvest, tree-ripe fruit and cold stored fruit). A total of 62 compounds were identified and classified into three groups (‘unique’ (31), ‘generic’ (11) and ‘frequent’ (20)) based on their frequency of occurrence. The aroma profiles of ‘Larry Anne’ and ‘Flavor King’ are the most affected by cold storage conditions and ‘Pioneer’ appears to be the least affected. All the cultivars have significantly different aroma profiles at all three of the functional stages with ‘Sapphire’, ‘Larry Anne’ and ‘Flavor King’ showing the largest differences. ‘Flavor King’, a plumcot, presented a ripe aroma profile that was much diverged from that of the true plums.
AFRIKAANSE OPSOMMING: Pruime met ‘n goeie smaak, aroma en eetkwaliteit lei tot herhaalde verkope en volhoubare aanvraag. Smaak sluit die nie-vlugtige stowwe (suikers en sure) in en is goed nagevors om die verbruikersvoorkeure te bevredig. Pruim aroma het egter nie dieselfde aandag geniet nie. Daar is beperkte literatuur beskikbaar wat handel oor die aroma van Japanese pruime en geen kon gevind word oor die effekte van lang koelopberging op die aromaprofiele nie. Die hoof doel van hierdie studie is om die veranderinge in die aromatiese komponente van Japanese pruime te ondersoek tydens die volwassewording- en rypwordingsprosesse asook die effekte van kommersiele koelopberging. Naby infrarooi (NIR) spektroskopie is ook geevalueer as ‘n nie-destruktiewe manier om pruim kwaliteitsparameters te bepaal met die doel om monstervariasie te beperk. In Artikel 1 is NIR spektroskopie gebruik om voorspellingsmodelle vir totale oplosbare suikers (TOS), totale suur (TS), suiker-tot-suur verhouding, fermheid en gewig te bepaal in drie kultivars (Pioneer, Laetitia en Angeleno) asook ‘n multi-kultivar model. Monsters is vir sewe opeenvolgende weke versamel en herhaal oor twee seisoene. TOS resultate toon uitstekende voorspelbaarheid (R2 = 0.817-0.955; RMSEP= 0.453-0.610 % Brix) maar TS modelle het egter nie so goed gevaar nie. Die suiker-tot-suur verhoudingsmodelle se resultate was vergelykbaar met die van TOS. Beide die fermheid- en gewigsmodelle het aanvaarbare resultate opgelewer. Die modelle vir ‘Pioneer’ en ‘Laetitia’ het ‘n beter voorspelbaarheidskapasiteit getoon as die van ‘Angeleno’. Alhoewel die multi-kultivar model beter presteer het as die enkel kultivar modelle op die R2-waardes was daar meer voorspellingsfoute. Hoe robuustheid is gevind i.t.v. seisoene, datagrense en kultivar vir al die TOS, TA en fermheidsmodelle. Artikels 2 en 3, die fokuspunt van die studie, handel oor die dinamika van die aromaprofiel van Japanese pruime. HS-SPME is in beide artikels gebruik on die aromatiese verbindings te ekstraeer gevolg deur GCTOFMS vir skeiding en identifikasie. In Artikel 2 is die aromatiese stowwe van drie kultivars (Pioneer, Laetitia en Angeleno) bepaal vir sewe opeenvolgende weke en sluit monsters van drie volwassenheidsstadiums in (onvolwasse, oes en boom-rypgemaakte pruime). ‘n Totaal van 35 verbindings is geidentifiseer waarvan tien as generies beskou kan word. Elke kultivar het vyf unieke komponente gehad en het gelei tot verskillende aromaprofiele vir elk van die volwassenheidsstadiums en diverse skeidingspatrone tydens die gebruik van diskriminant analise. Die studie is uitgebrei in Artikel 3 waartydens die aromatiese vlugtige stowwe van ses kultivars (Pioneer, Sapphire, Laetitia, Songold, Larry Anne en Angeleno) en een plumcot (Flavor King) bepaal is tydens drie funksionele stadiums (oes, boom-rypgemaak en koelopgebergde pruime). ‘n Totaal van 62 verbindings is geidentifiseer en in drie groepe geklassifiseer (‘uniek’ (31), ‘generies’(11) en ‘gereeld’ (20)) gebaseer op voorkomsfrekwensie. Die aromaprofiele van ‘Larry Anne’ en ‘Flavor King’ is die meeste deur die koelopberging geaffekteer en ‘Pioneer’ die minste. Al die kultivars het kenmerkend verskil t.o.v. hul aromaprofiele in al drie die funksionele groepe en ‘Sapphire’, ‘Larry Anne’ en ‘Flavor King’ het die grootste verskille getoon. ‘Flavor King’, die plumcot, het ook ‘n ryp aromaprofiel gehad wat baie van die van die egte pruime verskil het.

Повний текст джерелаIntroduction: Le Near Infra-Red Spectroscopy (NIRS) utilitisé durant la période opératoire peut réduire les complications neurologiques postopératoires. L'utilisation du NIRS chez la population pédiatrique et les variations associées au placement des senseurs sont sous étudiées. Objectifs: Explorer les performances du NIRS chez les enfants lors de chirurgies cardiaques; décrire les variations significatives du NIRS (20%) en comparaison aux niveaux témoins; établir des corrélations entre les événements et les variables mesurées; établir l'utilité d'un second senseur. Méthodes: Une revue rétrospective de données NIRS obtenues de façon prospective. Les relations observées seront évaluées avec les tests Student-t, chi-squared, et de régression logistique. Résultats: Des variations significatives en comparaison aux valeurs témoins ont été observées. Plusieurs de ces variations ont eu lieu lorsque les patients n'étaient pas supportés par la circulation extracorporelle ou lors de son initiation. Les augmentations et diminutions du NIRS sont significativement reliées au PaO2, à l'hématocrite, à la pression artérielle moyenne (p<0.05) et au paCO2 (p<0.01), respectivement. Des variations unilatérales du NIRS sont fréquentes, particulièrement chez les patients cyanosés et chez les patients males. Conclusion: Chez cette population pédiatrique, des déviations significatives du NIRS sont associées à certaines variables physiologiques. Le deuxième senseur ajoute des informations utiles.
