Abstract:
Purpose The purpose of this paper is to prepare amphiphilic block copolymers polyethylene adipate-block-polyethylene glycol (PEA-b-PEG)s and study their performance as plasticizers in rotogravure ink formulations. Design/methodology/approach Series of amphiphilic block copolymers (PEA-b-PEG1), (PEA-b-PEG2), (PEA-b-PEG3), (PEA-b-PEG4) and (PEA-b-PEG5) were prepared by the reaction of adipic acid, ethylene glycol and polyethylene glycol of different molecular weights (300, 1,000, 2,000, 10,000 and 20,000 g/mol), respectively. Full characterization of the prepared copolymers was achieved using Fourier Transfer Infrared Spectroscopy (FTIR), 1H NMR, thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The performance of the prepared copolymers as plasticizers for neat nitrocellulose resin were studied in different formulations, namely, R1, R2, R3, R4 and R5 containing copolymers (PEA-b-PEG1), (PEA-b-PEG2), (PEA-b-PEG3), (PEA-b-PEG4) and (PEA-b-PEG5), respectively. In addition to formula R0 that contains acetyl tributyl citrate (ATBC) as a commercial plasticizer. The mechanical properties, thermal analysis (DSC, TGA) and optical properties of the prepared formulations films were investigated. Theses amphiphilic block copolymers were then applied as plasticizers in different rotogravure ink formulations (F1, F2, F3, F4 and F5) and compared with commercial rotogravure ink formula (F0). The color measurements and optical properties of all formulations were achieved. Findings It was found that the performance of the prepared copolymers as plasticizers in different formulations based on nitro cellulose resin gives better gloss, adhesion for R1 compared with the other samples and color strength for F1 compared with F0. Finally, all the samples gave excellent plasticizing effect. Research limitations/implications The authors believe that type of these materials open the way for a new class of plasticizers that upon application or even degradation gives small ecofriendly molecules (adipic acid and or ethylene glycol moieties) taking into consideration the simplicity of the rout of the synthesis process. Practical implications The prepared ecofriendly (PEA-b-PEG)s could be successfully used as plasticizers instead of commercial plasticizer ATBC. Originality/value The research provides that the prepared (PEA-b-PEG)s with different molecular weights can act as plasticizers in rotogravure ink formulations, and their performance was acceptable and available.

Abstract:
To develop a method for the preparation of MgO nanoparticles, precatalyst synthesis from magnesium nitrate with ammonia and calcination was performed in presence of PEG in air. Without PEG, the catalysts are inactive. The conversion to hydroxide was performed using a PEG/MgO molar ratio of 1, but, before the calcination, excess of PEG was either saved (PEG1) or increased to 2, 3, or 4 (PEG 2–4). Catalysts were calcined at 400–660 °C and characterized using XRD, N2 adsorption-desorption, TGA, FTIR, and SEM. The FAME yield in the reactions with methanol depend on the PEG ratio used and the calcination temperature. The optimal calcination temperature and highest FAME yield in the 6 h reactions for catalysts PEG1, PEG2, PEG3 and PEG4 were 400 °C, 74%; 500 °C, 80%; 500 °C, 51% and 550 °C, 31%, respectively. The yield dependence on calcination temperature for catalysts with a constant PEG ratio is similar to that of a bell curve, which becomes wider and flatters with an increase in PEG ratio. For most catalysts, the FAME yield increases as the size of the crystallites decreases. The dependence of FAME and the intermediate yield on oil conversion confirms that all catalysts have strong base sites.

Abstract:
e12017 Background: Peg is used for CIN prevention. Plin, a novel, non-G-CSF agent is in Phase (Ph) 3 trials for CIN prevention and as an anticancer (NSCLC) agent. In contrast to Peg, Plin does not cause bone pain and maintains absolute neutrophil counts (ANC) within the normal range. Furthermore, Peg, but not Plin, increases Neutrophil-to-Lymphocyte Ratio (NLR) and Lymphocyte-to-Monocyte Ratio (LMR) to immune suppressive values; i.e. NLR>5 and LMR<3.2 (Blayney, ASCO 2018, ESMO 2018, ASCO-SITC 2018). We tested the effects on CIN, bone pain and immune-suppressive profile (i.e. NLR> 5 and LMR<3.2), comparing Plin+half Peg dose to full dose Peg alone (the current CIN standard of care). Methods: Early stage Breast Cancer patients (pts) received high febrile neutropenia (FN) risk TAC (docetaxel, doxorubicin, cyclophosphamide) and either full dose Peg 6 mg (Peg6; n=22) or Peg 3 mg (half dose) + Plin 20 mg/m2 (Peg3/Plin; n = 21) in a Ph 2 trial (NCT03294577). Peg was given ~24 hrs after TAC, and Plin ~30 min after TAC. Blood was drawn for ANC, NLR, MLR daily on Day (D) 0 to D15 in cycle 1. Validated bone pain assessments were done at predose D1, 2,3,4,6,7 and 8 in cycle 1. NLR and LMR were calculated from D6 on (ANC effects with Peg or Plin occur after D6). Results: Grade 4 and Grade 3/4 Neutropenia occurred in 59.1% and 81.2% of pts in the Peg6 arm vs 52.4% and 57.1% in the Peg3/Plin arm. Peg3/Plin was well-tolerated and non-inferior to Peg6 for duration of severe neutropenia (P<0.05). FN occurred in 1 pt each in Peg6 and Peg3/Plin. Bone pain with Peg3/Plin was less vs Peg6: frequency of pts with at least 1,3 or 5 days of bone pain was 90.9%, 36.7% and 18.2 % with Peg6, whereas 33.3%, 14.3% and 4.76% with Peg3/Plin (p<0.0001 for at least 1 day). Frequency of NLR≥5 and LMR≤3.2 was higher with Peg6 vs Peg3/Plin (p<0.045 to P<0.0004 between D8 to D15). Clinical trial information: NCT03294577. Conclusions: Half dose Peg combined with Plin is equally effective against CIN as full dose Peg, but with much less bone pain and immune-suppressive potential.[Table: see text]

Abstract:
Blends of poly(lactic acid) (PLA) and poly(ethylene glycol) (PEG) with various contents (0, 5, 10, 15, 20 and 30 weight %) and with different molecular weights (M&amp;macr;w = 1000, 4000 and 6000 g/mol), called respectively PEG1, PEG2, and PEG3 were prepared by melt blending. Since glass transition temperature (Tg), T? and loss factor (tan ?) are relevant indicators of polymer chain mobility, plasticization has been studied by dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). Low molecular weight (LMW) PEG enable increased miscibility with PLA and more efficient reduction of glass transition temperature (Tg) for concentrations of PEG less than 20%. This effect is not only enhanced by the LMW but also by increasing its content up to 20%. As expected, both T? and Tg decrease when increasing PEG molar mass and content up to 20%, which demonstrates the effectiveness of PEG to act as a plasticizer of PLA.

Abstract:
Background & Aims: To compare the eficacy and tolerance of sodium picosulphate/magnesium citrate(PMC) and polyethylene glycol (PEG) in a single or split dose regimen for colonoscopy bowel preparation.Methods: A prospective, randomized, endoscopist-blinded, multicenter study. The patients were randomly assigned to receive PMC (PMC4/0) or PEG (PEG4/0) in a single dose 4L day before colonoscopy or a split dose 2+2L PMC (PMC2/2) or 3+1L PEG (PEG3/1) one day before and in the morning before the colonoscopy. Each patient was interviewed to determine his/her subjective tolerance of the preparation before the procedure. The quality of bowel cleansing was assessed in a blinded test performed by multiple endoscopists using the Aronchick scale.Results: A total of 600 patients were enrolled, 88.2% were included in the analysis. Satisfactory bowel cleansing (Aronchick score 1 and 2) was signicantly more frequent when a split dose was used irrespective of the solution type (81.6% PMC2/2, 87.3% PEG3/1 vs. 73.0% PEG4/0, p = 0.024). In single dose regimens, PMC performed better than PEG (82.6% vs. 73.0%). Single or split dose PMC preparations were comparable. A PMC based solution was generally better tolerated than PEG regardless of the regimen used (p < 0.001). Nausea was reported mostly after the 4L PEG (32.8%, p < 0.001), incontinence after a split PMC dose (34.4%, p = 0.002), and bloating after the 4L PEG (38.0%, p < 0.001). There was no significant difference in the prevalence of vomiting.Conclusion: Colonic preparation with PMC yields similar results as a split PEG dose, regardless of whether PMC is administered in single or separate doses. PMC is better tolerated than any PEG-based preparation. A single 4L PEG the day before the colonoscopy is less appropriate for bowel cleansing.

Abstract:
After androgen deprivation therapy, a significant number of prostate cancer cases progress with a therapy-resistant neuroendocrine phenotype (NEPC). This represents a challenge for diagnosis and treatment. Based on our previously reported design of theranostic small-molecule prodrug conjugates (T-SMPDCs), herein we report a T-SMPDC tailored for targeted positron emission tomography (PET) imaging and chemotherapy of NEPC. The T-SMPDC is built upon a triazine core (TZ) to present three functionalities: (1) a chelating moiety (DOTA: 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) for PET imaging when labeled with 68Ga (t1/2 = 68 min) or other relevant radiometals; (2) an octreotide (Octr) that targets the somatostatin receptor 2 (SSTR2), which is overexpressed in the innervated tumor microenvironment (TME); and (3) fingolimod, FTY720—an antagonist of sphingosine kinase 1 that is an intracellular enzyme upregulated in NEPC. Polyethylene glycol (PEG) chains were incorporated via conventional conjugation methods or a click chemistry reaction forming a 1,4-disubstituted 1,2,3-triazole (Trz) linkage for the optimization of in vivo kinetics as necessary. The T-SMPDC, DOTA-PEG3-TZ(PEG4-Octr)-PEG2-Trz-PEG3-Val-Cit-pABOC-FTY720 (PEGn: PEG with n repeating ethyleneoxy units (n = 2, 3, or 4); Val: valine; Cit: citrulline; pABOC: p-amino-benzyloxycarbonyl), showed selective SSTR2 binding and mediated internalization of the molecule in SSTR2 high cells. Release of FTY720 was observed when the T-SMPDC was exposed to cathepsin B, and the released FTY720 exerted cytotoxicity in cells. In vivo PET imaging showed significantly higher accumulation (2.1 ± 0.3 %ID/g; p = 0.02) of [68Ga]Ga-DOTA-PEG3-TZ(PEG4-Octr)-PEG2-Trz-PEG3-Val-Cit-pABOC-FTY720 in SSTR2high prostate cancer xenografts than in the SSTR2low xenografts (1.5 ± 0.4 %ID/g) at 13 min post-injection (p.i.) with a rapid excretion through the kidneys. Taken together, these proof-of-concept results validate the design concept of the T-SMPDC, which may hold a great potential for targeted diagnosis and therapy of NEPC.

Abstract:
Solid-state high-resolution 13C/7Li nuclear magnetic resonance (NMR) study was performed on the phase structure and chain dynamics of PEG-PPG-PEGn/LiCF3SO3 (n=3, 6, 12) copolymer electrolytes. PEG repeating units and Li+ form PEG3:LiCF3SO3 crystalline complex and PE3/Li+ amorphous complex in all the samples. PPG repeating units and Li+ form different complexes with respect to O:Li+ feed ratio (denoted as PP/Li+-3/6/12). The 13C chemical shifts and half widths of the signals from PP/Li+-3/6/12 remain unchanged, which implies the structures of PP/Li+-3/6/12 are similar at least in a very short range. The half width of the 7Li signals from PP/Li+-3/6/12 becomes narrower and narrower as the Li+ concentration decreases. This indicates the chain mobility of the amorphous phase increases with the decrease of ionic concentration. Moreover, neat crystalline PEG, neat amorphous PEG and neat amorphous PPG start to appear when O:Li+ is greater than 3:1 and their contents increase with the increase of O:Li+. Overall, solid-state high-resolution NMR is a powerful and unique method for understanding the phase structure and chain dynamics of solid polymer electrolytes (SPEs), more applications of this technique to studies on SPEs is expecting.

Abstract:
Trial in Progress: Granulocyte colony stimulating factors (G-CSFs) (including Peg) reduce, but do not completely ameliorate CIN. Plinabulin is a novel, small molecule, single-dose-per cycle therapy, with equal activity against docetaxel CIN vs. Peg, but with several advantages: Plin has 1. Less bone pain, 2. Anticancer effects, and 3. Dosing 30 min after chemotherapy (chemo). The CIN nadir with Plin occurs in week 2 and with Peg in week 1 of the chemo cycle. All these features suggest a mechanism of action (MoA) with Plin that is different from Peg (Blayney, ASCO 2018; IASLC 2018). Neutrophil demargination with Plin and a reduced neutrophil transit time consistent with IL-6 signaling, and reversal of a LSK block in bone marrow, suggest protective rather than a stimulatory MoA for Plin in CIN (Blayney, SLB 2018; Ghosh, AACR 2018, Suwa, Am J Physiol 2000). Due to their differences in MoA, there is a strong rationale to combine Plin and Peg, as this offers the potential of better protection against CIN in both week 1 and 2 in the chemo cycle. In the Phase II portion of study BPI2358-106 (Study 106., NCT03294577), we evaluated the effects of the Plin combined with Peg on CIN and Bone Pain. Study 106 treated breast cancer (BC) patients with TAC with 6 mg Peg alone (Peg6), or Peg6+Plin. Plin dose was 20 mg/m2. Grade (Gr) 3 and 4 neutropenia frequency, duration of Gr 3 and 4 neutropenia (DSMN), and neutrophil nadir was based on absolute neutrophil counts, obtained on days 0, 1, 3, 6, 7, 8, 9, 10, 11, 12, 13, 15. Bone pain was assessed by a validated questionnaire on days 1, 2, 3, 4, 6, 7, 8, 9, and expressed as % of patients reporting bone pain. Phase II Results. The confirmatory phase 3 portion of study 106 will test addition of Plin to Peg6, which may offer superior protection against TAC CIN vs Peg alone without bone pain. The Plin/Peg combination is a novel CIN approach with the potential to optimize chemotherapy, by minimizing chemotherapy dose modifications due to CIN or bone pain.*p&lt;0.05; **p&lt;0.001; ***P&lt;0.01 Peg+Plin vs Peg 6mg Table Disclosures Blayney: BeyondSpring Pharmaceuticals: Research Funding.

Abstract:
The effect of pre-treating Moringa oleifera leaf powder (MOLP) with different levels of polyethylene glycol (PEG) on the growth performance, serum biochemistry, hematology, and meat quality parameters of Jumbo quail was evaluated. Two-week-old quail chicks (n = 432; 239.6 ± 6.48 g live-weight) were randomly allocated to six diets formulated by incorporating (10% w/w) untreated MOLP (PEG0) or MOLP pre-treated with PEG at 2.5% (PEG25), 5% (PEG50), 7.5% (PEG75), and 10% (PEG100) (w/w) into a standard grower diet (CON). Overall feed intake linearly increased with PEG levels. At week 4, significant quadratic trends were recorded for weight gain and feed conversion efficiency (FCE) but, at week 5, FCE linearly declined as PEG levels increased. Hemoglobin, phosphorus, and albumin showed quadratic trends, while calcium and chroma (1 h post-mortem) linearly declined in response to PEG levels. Diet PEG50 promoted a higher shear force value (2.41) than diets PEG0 and PEG25. The PEG50 diet promoted a similar (p > 0.05) shear force as diet CON. Based on the quadratic response for weight gain, the optimal PEG pre-treatment level was calculated to be 5.9%. It was concluded that MOLP condensed tannins negatively affect growth performance and should be ameliorated to enhance the utility of this nutraceutical source for Jumbo quail.

Abstract:
Bu çalışmada, depremlerin jeomanyetik alan verileri ile ilişkisi incelenmiştir. Öncelikle konu kapsamında deneysel çalışma olarak 3-4 Kasım 2021 boyunca meydana gelen jeomanyetik fırtınanın etkileri, çalışmanın ikinci aşamasında ise 17 Kasım 2021 Düzce depreminin (M=4,8) jeomanyetik alanlar üzerindeki etkileri araştırılmıştır. Bunun için gözlem (IZN) ve referans (PEG ve PAG) manyetometre istasyonlarında ölçülmüş jeomanyetik alanın X, Y ve Z bileşenlerinin verileri kullanılmıştır. Bu bileşenlerin zamansal çözünürlüğü 60 saniyedir. Ayrıca, jeomanyetik aktivite göstergesi olarak küresel jeomanyetik aktivite indisi (Kp) verileri kullanılmıştır. İlk önce Jeomanyetik fırtınadan ve depremden kaynaklı jeomanyetik anomalileri tespit etmek için istasyonlardaki jeomanyetik alan bileşenlerinin (X, Y, Z) jeomanyetik alan değişim oranı (ROG) ve jeomanyetik alan değişim oranı indeksi (ROGI) hesaplanmıştır. Daha sonra X, Y ve Z bileşenlerinin günlük değişimleri arasındaki ilişkiyi istatistiksel olarak tespit etmek için ROGI(X, Y, Z) değerlerini kullanılarak istasyon çiftlerinin (IZN-PEG, PEG-PAG ve IZN-PAG) korelasyon katsayıları (r) hesaplanmıştır. X, Y ve Z için gözlem ve referans manyetometre istasyonlarından elde edilen sonuçlar birbirleriyle karşılaştırılmıştır. Jeomanyetik fırtına boyunca IZN, PEG ve PAG için hesaplanan ROGI(X), ROGI(Y) ve ROGI(Z) değerlerinin çok benzer bir günlük değişime sahip oldukları tespit edilmiştir. 17 Kasım 2021 boyunca PEG ve PAG istasyonlarının ROGI(Y) değerleri birbirleriyle uyumlu bir günlük değişime sahipken, 08:15 EZ (Evrensel Zaman) ile 10:10 EZ arasında IZN istasyonunun ROGI(Y) değerlerinde bir artış (anomali) tespit edilmiştir. Bu sonuçlardan, IZN için tespit edilen anomalinin 17 Kasım Düzce depremi ile olası ilişkili sismomanyetik kaynaklı bölgesel öncül bir jeomanyetik anomali olarak değerlendirilebileceği öngörülmektedir.

Abstract:
To take advantages of single-walled carbon nanotubes (SWNTs) for cellular delivery of chemotherapeutic agents (e.g. doxorubicin) in order to decrease doxorubicin toxicity and increase its efficacy, we aimed to develop a novel approach to aqueous disperse and stabilize SWNTs through consequent steps of oxidation (oxSWNT) and PEG-PEI complexation (PEG-PEI-SWNT). Doxorubicin was loaded onto the modified SWNTs in alkalione pH with more considerable capacity ( 900 %) than those previously reported, due to complex formation with PEI proved by UV-visible spectroscopy. The loaded carrier was stable in physiologic simulated medium. Drug release was prolonged and dilution independent, but exhibited pH-dependent burst release that makes SWNTs as suitable in vivo drug carriers in acidic tumor milieu.

Abstract:
The effectiveness of the PEG ratio as a valuation tool has been a topical debate between market commentators ever since being popularised by Lynch (1989). This study examines the appropriateness of the fair value criteria of 1.0 (PEGL) in comparison with a time-series based share specific benchmarking model (PEGT). Furthermore, influencing factors of analyst forecasting accuracy, namely: the number of analyst contributions, forecast dispersion and forecast horizon, were tested and compared using sub-set portfolios for each category with the objective of identifying a possible optimal PEG trading rule strategy. The outcome showed a consistent outperformance of PEGT portfolios compared to PEGL portfolios and the market benchmark. Unexpected results were obtained for the impact of analyst forecasts on the performance of the PEG ratio with additional literature review providing possible reasons that analyst optimism may have a more influencing impact on the PEG ratio than forecasting accuracy. Finally, an optimised PEG trading rule strategy delivered annual abnormal returns of 5.4% (CAGR: 19.7%) for a PEGL portfolio, versus that of 13.7% (CAGR: 28.5%) for a PEGT portfolio. The ensuing methodology appeared to single out small cap firms with above market growth prospects. Copyright

Abstract:
Throughout the study of polymeric Langmuir monolayers at the air/water (A/W) interface, the Wilhelmy plate and Langmuir-Blodgett (LB) techniques along with Brewster angle microscopy (BAM) have been identified as key methods for acquiring structural, thermodynamic, rheological and morphological information. These techniques along with surface light scattering (SLS), a method for probing a monolayerâ s dynamic dilational rheological properties, will be used to characterize homopolymers, poly(ethylene oxide) (PEO) and poly(ethylene glycol) (PEG), and a new class of novel polymeric surfactants, telechelic (POSS-PEG-POSS) and hemi-telechelic (POSS-PEG) polyhedral oligomeric silsesquioxane (POSS) derivatives of PEG. PEO with number average molar mass, Mn > ~ 18 kgâ ¢mol-1 form stable spread Langmuir films at the A/W interface, while oligomeric PEG have ï -A isotherms that deviate from high molar mass PEO. Nonetheless, SLS reveals that the dynamic dilational viscoelastic properties of any Mn PEG(PEO) only depend on ï and not Mn. Likewise, POSS-PEG-POSS telechelics exhibit molar mass dependent ï -A isotherms, where low ï regimes (ï < 1 mNâ ¢m-1) have PEG-like behavior, but high ï regimes were dominated by POSS-POSS interactions. SLS studies reveal that the dynamic dilational moduli of POSS-PEG-POSS are greater than either PEO or an analogous POSS compound, trisilanolcyclohexyl-POSS. The ability to control rheological properties and the hydrophilic-lipophilic balance even allows one POSS-PEG-POSS (PEG Mn = 1 kgâ ¢mol-1) to form Y-type LB-multilayer films. For POSS-PEG systems, comparisons at comparable POSS:PEG ratios reveal short PEG chains (PEG Mn ~ 0.5 kgâ ¢mol-1) yield similar viscoelastic properties as POSS-PEG-POSS (PEG Mn ~ 1 kgâ ¢mol-1), while longer PEG chains (PEG Mn ~ 2 kgâ ¢mol-1) yield lower modulus films than comparable POSS-PEG-POSS. These differences are attributed to brush-like PEG conformations in short POSS-PEG versus mushroom-like PEG conformations in long POSS-PEG at the A/W interface. These results provide insight for designing PEG-based amphiphilic nanoparticles with controlled interfacial rheology.

Abstract:
Warren Buffet started an investment partnership of $100 in 1956 and has gone on to accumulate a personal net worth of over $60 billion. He started primarily as a value investor, and gradually changed over time to a strategy which uses the PEG ratio as its main tool. Peter Lynch, one of the most successful fund managers in history and had a compound annual growth rate of 29% for 13 years, was the man to first introduce the world to the PEG ratio. With such prominence, however, widespread use of previously successful strategies tend to render them ineffective due to everyone using them, and today the PEG ratio’s effectiveness as a valuation tool remains a topical debate between market commentators.This study sets out to determine if the PEG ratio adds value using JSE Main Board data from 2002 to 2012. Returns from five portfolios constructed directly from share quintiles based on PEG ratio magnitude are compared to returns of a portfolio constructed from the optimum quintile of value shares. The PEG ratio portfolio returns are examined based on 3 rebalancing period strategies, and on relative performance between the quintiles within each strategy.It is found that a 24 monthly rebalancing strategy provides superior returns to that of 3 or 12 monthly rebalancing for PEG quintiles of selected stocks. Furthermore, the lowest PEG ratio quintile in this strategy outperforms the value portfolio by a compound annual growth rate of 4.3%. The second lowest PEG ratio quintile portfolio performs slightly better to ensure that 40% of stocks selected based on the PEG ratio produced sustained superior returns to the optimum quintile value portfolio.

Abstract:
Les objectifs étaient d’étudier les effets de la pégylation sur les relations doses-concentrations-réponse à travers deux exemples qui sont le PEG-IFN beta 1a et le PEG-GRF, par la modélisation pharmacocinétique. La 1ère molécule étudiée était une glycoprotéine le PEG-IFN beta-1a. Une réduction de la clairance a été observée pour le PEG-IFN beta-1a par rapport à l’IFN beta-1a. L’effet du PEG-IFN beta-1a a été évalué à l’aide de 3 marqueurs pharmacodynamiques : beta2-microglobuline, néoptérine et 2’,5’-oligoadénylate synthétase. Aucune amélioration sur ces 3 marqueurs n’a été observée après l’injection du PEG-IFN beta-1a, comparé à l’IFN beta-1a, sur l’intensité et sur le délai de réponse. La 2ème molécule était un peptide le PEG-GRF. L’effet du PEG-GRF a été estimé par 2 marqueurs : IGF-1 et GH. Les constantes de vitesse d’apparition et de disparition de l’IGF-1 ne sont pas modifiées après injection du PEG-GRF, comparé au GRF. Le PEG-GRF présente une biodisponibilité supérieure à celle du GRF, vis-à-vis de l’IGF-1. Le PEG-GRF induit une réponse GH, représentée par des paramètres intégrés AUE sur différents intervalles de temps de 0 à 24h, plus importante par rapport au GRF
The objectives were to assess the effect of pegylation on the dose-concentration-response relationships throughout two examples PEG-IFN-beta-1a and PEG-GRF, using PK/PD modelling. The 1st molecule was a glycoprotein the PEG-IFN-beta-1a. A reduced clearance has been observed for PEG-IFN-beta-1a. The effect of PEG-IFN-beta-1a was assessed with 3 pharmacodynamic (PD) markers: beta2-microglobulin, neopterin and 2’,5’-oligo adenylate synthetase. By comparison with IFN-beta-1a, no improvement was observed in terms of magnitude and time course in the response of the PD markers following PEG-IFN-beta-1a injection. The 2nd molecule was a peptide the PEG-GRF. The effect of PEG-GRF-1a was assessed with 2 PD markers: GH and IGF-1. The absorption rate constant and the elimination rate constants remained unchanged following PEG-GRF administration, compared to GRF. Regarding the IGF-1 marker, PEG-GRF has a higher bioavailability compared to those of the GRF. The GH response, represented by AUE on different time intervals from 0 to 24 h, was higher following PEG-GRF injection, compared to GRF. Those 2 examples are representative of the variety in the properties of pegylation reported in literature

Abstract:
Peg solitaire is a game in which pegs are placed in every hole but one and the player jumps over pegs along rows or columns to remove them. Usually, the goal of the player is to leave only one peg. In a 2011 paper, this game is generalized to graphs. In this thesis, we consider a variation of peg solitaire on graphs in which pegs can be removed either by jumping them or merging them together. To motivate this, we survey some of the previous papers in the literature. We then determine the solvability of several classes of graphs including stars and double stars, caterpillars, trees of small diameter, particularly four and five, and articulated caterpillars. We conclude this thesis with several open problems related to this study.

Abstract:
Trees and shrubs are potentially important sources of food for livestock in many parts of the world, but their use is limited by tannins. Tannins reduce food intake by decreasing digestibility or by causing illness. Supplementing cattle, sheep, and goats with polyethylene glycol (PEG), which has a high affinity for binding tannins and thus attenuating their aversive effects, increases intake of high-tannin foods and improves weight gains and wool growth. The objectives of this proposal were: Objective 1: To further delineate the conditions under which PEG affects intake of high-tannin foods. Objective 2: To ascertain if animals self-regulate intake of PEG in accord with the tannin content of their diet under pen, paddock, and field conditions. Objective 3: To determine how nutritional status and PEG supplementation affect preference for foods varying in nutrients and tannins. Objective 4: To assess the effects of PEG on food selection, intake, and livestock performance in different production systems. The results from this research show that supplementing livestock with low doses of PEG increases intake of high-tannin foods and improves performance of cattle, sheep, and goats. Neutralizing the effects of tannins with supplemental PEG promotes the use of woody species usually considered useless as forage resources. Supplementing animals with PEG has the potential to improve the profitability - mainly milk production - of high-yielding dairy goats fed high-quality foods and supplemented with browse in Mediterranean areas. However, its contribution to production systems utilizing low-yielding goats is limited. Our findings also support the notion that supplemental PEG enhances the ability of livestock to control shrub encroachment and to maintain firebreaks. However, our work also suggests that the effectiveness of supplemental PEG may be low if alternative forages are equal or superior in nutritional quality and contain fewer metabolites with adverse effects.
