Résumé :
A strategy in preparing a family of hexameric porphyrin cubes based on the interplay of Sn(IV)-O and Ru(II)-N interactions is described. In this first iteration, we have prepared the heptamer [SnIV(TPyP)·(4)2][Ru(CO)(TPP)]6 (4 = (E)-(3-(4-pyridyl)acrylate)) constituting a 5,10,15,20-tetra(4-pyridyl)porphyrin (TPyP) core and 5,10,15,20-tetraphenylporphyrin (TPP) faces and compared its formation by stepwise and "one-pot" strategies where up to nine components are assembled in a single step in a regiospecific manner. In one example, the heptamer is formed around the template [SnIV(TPyP)·(4)2] bearing pyridine groups in which the nitrogens radiate octahedrally along each vertex. The ability to modulate the axial vertex through choice of pyridine is also demonstrated. 1H NMR measurements on [SnIV(TPyP)·(4)2][Ru(CO)(TPP)]6 indicate that the protons on the core template are extremely shielded as a result of the anisotropy of the peripheral porphyrin units. Various NMR techniques, including NOESY experiments, have been used to characterise the heptamer in solution.

Résumé :
The peroxidase-like catalytic activities of some synthetic porphyrins following substitution in apo-horseradish peroxidase (apo-HRP) were studied by UV-vis and fluorescence spectrophotometries in buffer potassium phosphate solution at pH 7. The insertion of these synthetic porphyrins in apo-HRP is very difficult, due to steric hindrances between coordinated metals in porphyrins and the side-chains of amino acids in native protein. However, because of planar coordination following insertion in an active site of apo-HRP tetrapyridylporphyrin(TPyP), a metal-free porphyrin, adsorbs free metal ions from the environment and shows higher peroxidase-like catalytic activity than other new synthetic porphyrins. The results indicate that the metal-free porphyrins with optimum Reinheitzahl (RZ) show higher catalytic activity relative to others. The fluorescence emission of TPyP only, and of apo-HRP-TPyP, displayed significantly different wavelengths for the maximum aromatic fluorescence intensity. The λmax for apo-HRP-TPyP was around 447 nm, while for TPyP, alone, it increased to 463 nm, which showed that the aromatic groups' surroundings changed upon substitution of porphyrins in a low polar environment.

Résumé :
A Ti-TPyP reagent, i.e., an acidic aqueous solution of oxo[5,10,15,20-tetra(4-pyridyl)porphyrinato]titanium(IV) complex, TiO(tpyp), was developed as a highly sensitive and selective spectrophotometric reagent for the determination of traces of hydrogen peroxide. The reagent exhibited a single absorption peak at 432 nm, and the addition of hydrogen peroxide to the reagent gave rise to a new peak at 450 nm, with height being proportional to the added hydrogen peroxide concentration. Recently we succeeded in clarifying the reaction specificity of the TiO(tpyp) complex to hydrogen peroxide from the viewpoint of the reaction mechanisms and molecular orbitals based on ab initio calculations. In the present study, we performed ultraviolet–visible (UV-Vis) spectral simulations for individual species in the proposed reaction mechanisms based on the theoretical calculations carried out using the Zerner's intermediate neglect of differential overlap (ZINDO) method, since the assignment of the observed absorption peaks to the respective reaction species is important to confirm the reliability of the analysis of hydrogen peroxide using the Ti-TPyP reagent. The absorption peaks at 432 nm and 450 nm were assigned to a H2O-adduct structure of the protonated TiO(tpyp) complex and the important structure corresponding to the monoperoxo TiO(tpyp) complex, respectively, under acidic conditions. Particularly, it should be noted that the addition of water molecules to the protonated TiO(tpyp) complex affects the maximum absorption wavelength appreciably. Taking the addition of water molecules to the complex into consideration, the reaction mechanism proposed previously was revised in this study. The results should contribute to providing a new way to evaluate analytical reagents.

A series of new yttrium(III) double-decker complexes with the same and different phthalocyaninato and porphyrinato ligands has been prepared. The homoleptic complexes Y ( P )2 ( P = Pc *(C7 H 15)8, Pc *( OC 5 H 11)8; Pc * = 2,3,9,10,16,17,23,24-octasubstituted phthalocyaninate) have been synthesized by treating yttrium(III) acetylacetonate ( Y ( acac )3· H 2 O ) with the phthalonitriles C 6 H 2 R 2( CN )2 ( R = C 7 H 15, OC 5 H 11) in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The heteroleptic analogues Y ( P )( Pc ) ( P = Pc *( C 7 H 15)8, Pc *( OC 5 H 11)8; Pc = unsubstituted phthalocyaninate) and Y ( P )( Por ) ( P = Pc , Pc *( C 7 H 15)8; Por = meso-tetraphenylporphyrinate (TPP), meso-tetra(4-pyridyl)porphyrinate (TPyP)) have been prepared by the base-catalysed tetramerization of the corresponding phthalonitriles using Y ( P )( acac ) ( P = Pc , TPP , TPyP ) as templates. The syntheses along with the spectroscopic and electrochemical properties of these novel double-deckers are described.

Résumé :
The interaction between human serum albumin (HSA) and the non-charged synthetic photosensitizer 5,10,15,20-tetra(pyridine-4-yl)porphyrin (4-TPyP) was evaluated by in vitro assays under physiological conditions using spectroscopic techniques (UV-vis, circular dichroism, steady-state, time-resolved, synchronous, and 3D-fluorescence) combined with in silico calculations by molecular docking. The UV-vis and steady-state fluorescence parameters indicated a ground-state association between HSA and 4-TPyP and the absence of any dynamic fluorescence quenching was confirmed by the same average fluorescence lifetime for HSA without (4.76 ± 0.11 ns) and with 4-TPyP (4.79 ± 0.14 ns). Therefore, the Stern–Volmer quenching (KSV) constant reflects the binding affinity, indicating a moderate interaction (104 M−1) being spontaneous (ΔG°= -25.0 kJ/mol at 296 K), enthalpically (ΔH° = -9.31 ± 1.34 kJ/mol), and entropically (ΔS° = 52.9 ± 4.4 J/molK) driven. Binding causes only a very weak perturbation on the secondary structure of albumin. There is just one main binding site in HSA for 4-TPyP (n ≈ 1.0), probably into the subdomain IIA (site I), where the Trp-214 residue can be found. The microenvironment around this fluorophore seems not to be perturbed even with 4-TPyP interacting via hydrogen bonding and van der Waals forces with the amino acid residues in the subdomain IIA.

Résumé :
A mixed (phthalocyaninato) (porphyrinato) europium triple-decker complex, named (TPyP)Eu[Formula: see text][Pc(OC[Formula: see text]H[Formula: see text]][Formula: see text][TPyP [Formula: see text] dianion of 5,10,15,20-tetra(4-tert-pyridyl) porphyrin, Pc(OC[Formula: see text]H[Formula: see text] 2,3,9,10,16,17,23,24-octabutoxyphthalocyaninate] is synthesized and characterized by MALDI-TOF, 1HNMR, UV-visible spectra and differential pulse voltammetry techniques. Introduction of electron-donating butoxy groups at the periphery of the phthalocyanine ligands and electron-withdrawing pyridyl substituents onto the meso-positions of the porphyrin ring not only increases the solubility of the triple decker but successfully tunes the HOMO and LUMO energy levels into a soluble ambipolar organic semiconductor. A simple quasi-Langmuir–Shäfer (QLS) method is used to fabricate self-assembled film of (TPyP)Eu[Formula: see text][Pc(OC[Formula: see text]H[Formula: see text]][Formula: see text]. Excellent sensitivity, reproducible [Formula: see text]-type and [Formula: see text]-type responses to electron-accepting gas NO[Formula: see text] and electron-donating gas NH[Formula: see text] are found for the films of (TPyP)Eu[Formula: see text][Pc(OC[Formula: see text]H[Formula: see text]][Formula: see text]complex at room temperature. The detection limit towards NO[Formula: see text] and NH[Formula: see text] is as low as 0.4 ppm and 1 ppm, respectively, with percentage current change of 4.2% and 1.6%, depending on the uniform molecular packing and intermolecular interactions among the triple decker molecules. The present results represent not only the excellent example of ambipolar triple-decker phthalocyanine-based sensors obtained by a solution-based method, but more importantly provide a new strategy for the molecular design to obtain soluble ambipolar organic semiconductors in sensing device fabrication.

Résumé :
The UV-vis spectral, electrochemical and resonance Raman data of [meso-tetrakis(4-pyridyl)porphyrinato]nitridomanganese(V), MnN(TPyP) , were investigated. MnN(TTP) (where ( TTP )2− = dianion of meso-tetrakis(p-tolyl)porphyrin) and MnN(OEP) (where ( OEP )2− = dianion of 2,3,7,8,12,13,17,18-octaethylporphyrin) were also examined in comparison. Cyclic voltammetry of MnN ( TPyP ) showed an irreversible oxidation wave at +1.22 V and two redox couples at −1.05 and −1.40 V vs. Ag / AgCl , respectively. According to spectroelectrochemical studies, the first and the second reductions involved formation of the porphyrin anion and dianion, respectively, the latter leading to a phlorin. The electron-withdrawing 4-pyridyl substituent shifted the redox potential of the porphyrin ring to a more positive value. However, the bond strength of the Mn - N triple bond was not affected. Resonance Raman studies indicated that the Mn≡N stretching frequencies (νMnN) occurring within 1050 ± 1 cm−1 in various solvents did not change significantly. The hydrogen-bonding between methanol and MnN ( TPyP ) lowered νMnN to 1040 cm−1. A further lowering of νMnN was found in the presence of nitrogeneous bases such as imidazole (ImH), piperidine (Pip) and pyridine (Py) and may be due to coordination to the manganese center. νMnN is correlated with the pKa's of a series of pyridines.

Résumé :
In questa tesi si cercherà di analizzare se un’eventuale adesione al TPP sia negativa per l’agricoltura e la politica agricola giapponese. Il primo capitolo avrà lo scopo di riassumere brevemente le peculiarità della politica agricola giapponese. Si analizzerà l’organizzazione della Nokyo e come questa sia stata fondamentale per la mobilitazione elettorale, creando così un forte legame con il Jiminto e con il Ministro dell’agricoltura (MAFF). Verrà esaminato inoltre come la riforma elettorale del ‘94, quella amministrativa del ’99 e la liberalizzazione finanziaria, abbiano indebolito il potere della Nokyo e la sua influenza sui governi. Il secondo capitolo avrà l’obiettivo di descrivere sinteticamente i cambiamenti della politica agricola giapponese nel tempo. Cercando di capire se la decisione di aderire al TPP sia un fatto isolato oppure il risultato di un cambiamento già in atto della politica agricola giapponese. Il terzo capitolo intende fornire un’analisi del processo di liberalizzazione del mercato agricolo giapponese. Partirà dall’adesione al GATT, analizzandone i punti critici per l’agricoltura giapponese. Si soffermerà sul cambio di politica estera giapponese, basato dalla sottoscrizione di FTA, ed analizzerà come i prodotti agricoli vengono trattati in questi accordi e che impatto hanno avuto sull’agricoltura giapponese. Il quarto capitolo si concentrerà invece sul TPP. Fornirà una cronologia dell’evoluzione delle trattative per l’adesione al TPP dal governo Minshuto fino ad oggi col secondo governo Abe, si sottolineerà quali fattori hanno spinto il governo Abe ad iniziare le trattative. Si concentrerà in particolare sul TPP nell’ambito agricolo, analizzando in che modo potrebbe influenzare l’agricoltura giapponese e come i paesi già aderenti al TPP abbiano trattato i prodotti agricoli più sensibili. In seguito, esaminerà le posizioni dei principali partiti politici sul tema del TPP, approfondirà le ragioni dell’opposizione all’adesione, e la posizione della Nokyo. Infine si vedrà come si è evoluta l’idea del Jiminto passando da una posizione di opposizione al TPP ad una posizione favorevole, creando del dissenso all’interno del partito stesso. Nelle conclusioni cercherò di valutare se secondo quanto raccolto nei capitoli precedenti, un’adesione al TPP sia veramente negativa per l’agricoltura e la politica agricola giapponese.

Résumé :
L'exploration de la reaction d'hydroformylation du styrene en presence du complexe rhcl(co)(tpp) 2 (tpp = 1,2,5-triphenyl-1h-phosphole) a ete menee dans plusieurs directions : l'etude de la cinetique de reaction, l'identification des complexes impliques dans la reaction catalytique, la recherche des intermediaires reactionnels et la comparaison avec les systemes rh 4(co) 1 2/pph 3 et rh 4(co) 1 2/tpp. Le premier chapitre decrit l'appareillage utilise pour realiser l'etude cinetique (reacteur, capteurs, systemes de mesure et de regulation) et le logiciel d'acquisition des mesures. L'exploitation des resultats conduit a une equation de vitesse difficile a interpreter et a correler avec un mecanisme reactionnel. Dans le deuxieme chapitre, l'etude du melange reactionnel par les spectroscopie de rmn 1h, 3 1p et 1 3c, revele l'existence du complexe dinucleaire rh 2(-co) 2(co) 4(tpp) 2 et celle du complexe mononucleaire hrh(co) 2(tpp) 2, tous deux impliques dans de multiples reactions d'echanges intermoleculaires et conformationnels. Le chapitre 3 rassemble les analyses, par spectroscopie ir, des melanges reactionnels prepares sous differentes atmospheres gazeuses. Elles confirment l'existence des complexes reveles par l'etude rmn et permettent d'en preciser la geometrie. Le chapitre 4 resume la recherche des intermediaires reactionnels par les spectroscopies ir et de rmn. Les substitutions isotopiques ( 2h et 1 3c) revelent la reversibilite de la formation de complexes rhodium-alkyle, permettent la caracterisation de complexes rhodium-acyle et la mise en evidence de reactions parasites (effet inhibiteur sur la vitesse de reaction). Le chapitre 5 reprend l'analyse et le traitement des mesures cinetiques, a l'aide d'un logiciel de calcul adapte. Les resultats d'experiences complementaires, associes a ceux des chapitres precedents, permettent de proposer une equation generale de vitesse et un mecanisme reactionnel en bon accord.

Résumé :
In our previous works, some holeburning results in organic materials with charge transfer were given. We achieved the photon-gated holeburning in a system containing the electron acceptor (p-hydroxybenzaldhyde (PHBA)) and the electron donor (Zn-tetraphenylbenzoporphyrin (Zn-TPBP) doped in a matrix (poly-methylmethacrylate (PMMA) ) [1-3]. In this paper, we will report the single photon holeburning at 25K in p- tetraphenylporphyrin (TPP) embedded in the matrix of polymethylcellulose. The mechanisms of holeburning and holefilling are discussed.

Résumé :
A novel type of flexible composite with tungsten powder filled in polymers (TPFP) homogeneously was developed as an alternative to lead (Pb) based radiation shields used in nuclear industries. TPFP had a density in the range of 4 to 11.3 g/cm3, which can be tailor-made according to the applications. In addition to the advantage of lower toxicity over Pb-based shielding, TPFP can be formed into various shapes, such as pipe shields, pipe wraps, safe floor shields, blankets, etc. The mechanical properties and attenuation of γ-ray was investigated for the developed TPFP.

Résumé :
Tamm plasmon polariton (TPP) is proposed to demonstrate the ultra-sharp resonance and strong fields confinement. Different applications from UV to NIR are presented, including selective thermal emissions, UV lasers, chirality mirrors, sensors, etc. A DBR-side TPP structure can overcome the limitations of the intrinsic property of the metal, which can support a stronger and narrower TPP resonance. The lithography-free, low cost, and refractory feature of the DBR-side TPP structures pave more possibilities for applications in nanophotonics.

Résumé :
The smallest forming unit in two-photon photopolymerization (TPP) micro-manufacturing technology is the voxel, the appearance of which resembles a spheroid. Traditional TPP micro-manufacturing is planned using the minor-axis dimension of a spheroid, which is smaller than its major-axis, thus, the spatial resolution can achieve submicron level. TPP can be used to manufacture microstructures with complex shapes. However, such fine spatial resolution inevitably lowers the overall manufacturing speed. For a microstructure with a height of hundred micrometers, the prolonged manufacturing time substantially increases the risk of manufacturing failure. Whereas typical methods use the minor-axis dimension for manufacturing planning, this study developed a novel major-axis planning (MAP) method that uses the longest dimension of the voxel. In this study, the MAP was realized in a 4-axis micro-manufacturing system (i.e., a rotation axis was added to the 3-axis motion stage). Specifically, a specially designed L-type glass substrate was first placed on the rotation axis and was rotated 90°, rendering the working plane parallel to laser beams. Subsequently, horizontal laser scanning was performed, during which the laser focus moved from the working plane horizontally, to polymerize a high-aspect-ratio structure. The commercial polymer OrmoComp was used with the MAP; only 10 s was required to fabricate a microstructure that had a height of 100 μm and an aspect ratio of 17. This study verified that TPP micro-manufacturing on a voxel’s major axis can fabricate microstructures. Moreover, the L-type glass substrate can be controlled programmably to rotate an L-type glass substrate for 4-axis TPP micro-manufacturing in the future.

Résumé :
It is well known that porphin derivatives such as tetraphenylporphin (TPP) molecularly dispersed in organic polymers such as polymethylmethacrylate (PMMA) exhibit photochemical hole burning (PHB). In this kind of porphin/polymer system of simple dispersion type, large irreversible broadening of photochemical holes is observed even at extremely low temperatures around liquid helium temperature [1]. This broadening, or spectral diffusion, is caused by the energy shift of the electronic states of the porphin molecule brought about by the structural changes which take place in the organic amorphous polymer. The reduction of this spectral diffusion is one of the main subjects for the possible application of PHB to high-density optical memory. In the previous paper [1], we reported on the spectral diffusion in the copolymer of methylmethacrylate (MMA) and TPP derivative with four functional groups and showed that the spectral diffusion is suppressed by the covalent bonds formed between TPP and the host polymer. Besides, we reported that the hydrogen bonds formed in the host polymer also suppress the spectral diffusion, which was confirmed for the several porphin derivatives with ionic substituents dispersed in polyvinylalcohol (PVA), one of the most efficient hydrogen bonding polymers [2]. Then, we may expect still less spectral diffusion in such materials that have both the covalent bonds between TPP and the host polymer, and the hydrogen bonds in the latter. In this study, we will show that this anticipation is true.

Texte intégral
Résumé :
Dynamic response of all PWR reactors is generated by the turbulent pressure pulsations (TPP) in the boundary layer on the surface of core barrel and acoustic pressure pulsations (APP) generated by main circulation pumps (MCP). While TPP have character of the white noise in the frequency range 〈0; 35〉 Hz, APP generate discrete set of frequencies called revolution and blade frequencies. The rotor revolutions of individual MCPs are slightly different and are changing as the operation conditions are changing. It results in the varying beat character of reactor vibrations. Results of numerical simulations and experimental measurements are presented.

Résumé :
Temporal point processes (TPP) are probabilistic generative models for continuous-time event sequences. Neural TPPs combine the fundamental ideas from point process literature with deep learning approaches, thus enabling construction of flexible and efficient models. The topic of neural TPPs has attracted significant attention in the recent years, leading to the development of numerous new architectures and applications for this class of models. In this review paper we aim to consolidate the existing body of knowledge on neural TPPs. Specifically, we focus on important design choices and general principles for defining neural TPP models. Next, we provide an overview of application areas commonly considered in the literature. We conclude this survey with the list of open challenges and important directions for future work in the field of neural TPPs.

Résumé :
The CPTPP allows economies and countries in other regions to formally incorporate trade flows with the Asia-Pacific and Pacific Rim, as well as boost trade with countries in these regions. The TPP was signed by 12 countries in February 2016 and on December 9 of the same year the Japanese government of Prime Minister Shinzo Abe approved the TPP by a majority in the House of Representatives. However, in January 2017, Trump, as the new President of the United States, officially declared the withdrawal of the United States from the TPP to fulfill one of his election promises. In the end, Trump's decision to withdraw the United States from the TPP has done nothing but exclude the United States from strengthening its trade ties with the Pacific Rim, while establishing the new 21st century rules for multilateral trade. In this context, this paper focuses on the study of two axes: the process and strategy of U.S. trade policy, and the current situation and a perspective of the TPP 11.

PERT prescribing in pancreatic cancer. Dlab, janvier 2023. http://dx.doi.org/10.53764/rpt.a0b1b51c7a.

Texte intégral
Résumé :
Background: Cancer treatments were variably disrupted during the COVID-19 pandemic. Despite UK national guidelines recommending pancreatic enzyme replacement therapy to all people with unresectable pancreatic cancer, observational studies demonstrate under-prescribing. Aim: To investigate the impact of the COVID-19 pandemic on the prescribing of pancreatic enzyme replacement to people with unresectable pancreatic cancer. Methods: With the approval of NHS England, we conducted a cohort study using 24 million health records through the OpenSAFELY-TPP research platform. We modelled prescribing rates from 1st January 2015 to 30th November 2022 and investigated the effect of COVID-19 with multivariable linear regression. Results We found no reduction in pancreatic enzyme replacement therapy during the COVID-19 pandemic. Overall, since 2015, the rates of prescribing increased steadily over time by 1% every year. The national rates ranged from 41% in 2015 to 50% in 2022. There was substantial regional variation. The highest rates of 50% to 60% were in the West Midlands and lowest (20% to 30%) in London. Conclusions: The COVID-19 pandemic did not affect PERT prescribing in unresectable pancreatic cancer. Although overall rates increased over time, substantial under-prescribing persists. At just under 50% in 2022, the rates were still below the recommended 100% standard. Despite the national guidelines, under-prescribing of PERT continued and has improved only marginally since their publication. This could be an important missed opportunity to reduce morbidity for patients with pancreatic cancer. The research into barriers to prescribing of PERT and geographic variation is urgently needed to improve quality of care.
