Abstract
SQUAMOSA PROMOTER BINDING-LIKE (SPL) proteins constitute a large family of transcription factors known to play key roles in growth and developmental processes, including juvenile-to-adult and vegetative-to-reproductive phase transitions. This makes SPLs interesting targets for precision breeding in plants of the Nicotiana genus used as e.g. recombinant biofactories. We report the identification of 49 SPL genes in Nicotiana tabacum cv. K326 and 43 SPL genes in Nicotiana benthamiana LAB strain, which were classified into eight phylogenetic groups according to the SPL classification in Arabidopsis. Exon-intron gene structure and DNA-binding domains were highly conserved between homeologues and orthologues. Thirty of the NbSPL genes and 33 of the NtSPL genes were found to be possible targets of microRNA 156. The expression of SPL genes in leaves was analysed by RNA-seq at three different stages, revealing that genes not under miR156 control were in general constitutively expressed at high levels, whereas miR156-regulated genes showed lower expression, often developmentally regulated. We selected the N. benthamiana SPL13_1a gene as target for a CRISPR/Cas9 knock-out experiment. We show here that a full knock-out in this single gene leads to a significant delay in flowering time, a trait that could be exploited to increase biomass for recombinant protein production.

Abstract
Abstract
Background
Inflammatory processes play an important role in pulmonary arterial hypertension (PAH) pathophysiology. We previously confirmed that in case of right ventricle (RV) failure, changes of cytokines' levels are correlated with myocardial metabolic and hemodynamic alterations observed in PET/MRI hybrid imaging. Presence of late gadolinium enhancement (LGE) in RV insertion points (RVIPs) has been found in majority of PAH patients and is often recognized as evidence of myocardial fibrosis due to RV pressure overload. As qualitative and/or quantitative assessments of LGE may vary due to natural PAH progression or specific therapy, we hypothesized that simple presence of LGE at RVIPs is not unequivocal to fibrotic tissue (without metabolic activity).
Purpose
To check the relationship between LGE mass and 18F-fluorodexyglucose uptake in RV insertion points in PAH patients using PET/MRI hybrid imaging.
Methods
Twenty-eight clinically stable PAH patients (49.9±15.9 years) had simultaneous PET/MRI scans during baseline and follow up (FU) visits, Figure. 18F-fluorodexyglucose (FDG) was used as a tracer and its cardiac uptake was presented as a maximum standardized uptake value (SUV) for RV insertion points (SUV in RVIPS). Septal delayed enhancement mass was quantified in RVIPs and presented as LGE mass. Occurrences of clinical end-points (CEP, defined as death or clinical deterioration) were assessed during 24 months observation.
Results
LGE was found in RVIPs of all PAH patients. Mean LGE mass was 6.32±4.41 g and mean SUV in RVIPS was 7.28±5.36. Follow up values were 8.01±7.75g (p=0.4) and 5.80±3.16 (p=0.16), respectively. We observed significant correlation between baseline SUV in RVIPS and mean pulmonary pressure, mPAP (r=0.49, p=0.04) but no correlation was found between LGE mass and SUV in RVIPS (in both baseline and FU scans).
Between baseline and follow up visits, 16 patients had CEP and needed PAH therapy escalation. CEP+ group of PAH patients presented higher baseline LGE mass (7.53±4.75 vs 3.92±2.21, p=0.04) and SUV in RVIPS (7.27±5.42 vs 6.01±4.52, p=0.4). In all CEP patients who initiated prostacycline therapy and survived (n=8, 50%), SUV in RVIPS decreased in FU PET scans together with an increase in LGE mass in MRI. At FU visits we also observed significant improvement of MRI-derived RV ejection fraction (45.1±9.6% to 52.4±12.9%, p=0.01), and mPAP (50.5±18.3 to 42.8±18.6 mmHg, p=0.03).
Conclusions
Effective PAH therapy have an impact on both LGE mass and FDG uptake in cardiac local tissue changes. Since there was no correlation between LGE mass and FDG uptake RV insertion points, the question arises what the cause of these LGE changes is. Increased fibrosis should cause diminished local glucose metabolism. This phenomenon opens new questions concerning pathophysiology processes in RVIPs and requires confirmation on bigger PAH population.

Abstract
Abstract
Introduction
Classic risk factors of atherosclerosis may contribute to cardiovascular (CV) risk in patients (pts) with pulmonary hypertension associated with congenital heart disease (PAH-CHD), but their prevalence is poorly studied.
Purpose
We evaluated a large cohort of Polish PAH-CHD patients (PAHpts) treated with specific therapies with regard to prevalence of classic risk factors for atherosclerosis.
Methods
A multicenter observational snapshot registry was conducted under the auspices of Polish Cardiac Society to study PAH pts, identified in centers treating >5 such pts in years 2008–2018. The analysis included 250 PAH-CHD pts, including non-corrected CHD – predominantly Eisenmenger Syndrome (Gr. 1, 224 pts, mean age 42±2 years, 63% females) and pts after heart disease correction (Gr. 2, 26 pts, mean age 42±6.5 years, 62% females). The incidence of classic CV risk factors was compared in both groups.
Results
The prevalence of risk factors was considerable considering young age of the cohort and statistically similar in both groups (Figure). Hypertension was present in 14% in Gr. 1 and 15% in Gr. 2. The incidence of diabetes was comparable in both groups (3% vs. 4%). Hyperlipidemia was nearly numerically twice as frequent in Gr. 1 (23% vs. 12%, p=0.18). Current smokers (1%) were only present in Gr. 1, while history of smoking was 4% in both groups. Symptomatic atherosclerosis of peripheral arteries was twice as frequent in Gr. 1 (8% vs. 4%, p=0,71). There was no difference regarding prior stroke (3,6% vs 4%, p=0,63). Chronic kidney disease and atrial fibrillation were one and a half more often in Gr. 1 (respectively, 12% vs. 8%, p=0,81; 12% vs. 8%, p=0.75). Mean heart rate was 72±2 bpm in Gr. 1 and 77±7 bpm in Gr. 2. Gastrointestinal bleeding was reported only in Gr. 1 (2.7%). SCORE calculated risks were low due to low age, but high risk was identified in 9.3% of Gr. 1 and 20% of Gr. 2 (p=0.096).
Conclusions
Based on our data from national survey, classic atherosclerosis CV risk factors are not uncommon in the population of relatively young patients with PAH-CHD, parallel to improved longevity. Selected pts from both groups present with elevated risk of death from atherosclerotic complications. This finding may influence the overall mortality risk in PAH-CHD population and reflects new challenges in management despite progress in specific therapies of pulmonary hypertension.

Abstract
Herein, we investigated the molecular dynamics as well as intramolecular interactions in two primary monohydroxy alcohols (MA), 2-ethyl-1-hexanol (2EHOH) and n-butanol (nBOH), by means of broad-band dielectric (BDS) and Fourier transform infrared (FTIR) spectroscopy. The modeling data obtained from dielectric studies within the Rubinstein approach [ Macromolecules 2013, 46, 7525-7541] originally developed to describe the dynamical properties of self-assembling macromolecules allowed us to calculate the energy barrier (Ea) of dissociation from the temperature dependences of relaxation times of Debye and structural processes. We found Ea ∼ 19.4 ± 0.8 and 5.3 ± 0.4 kJ/mol for the former and latter systems, respectively. On the other hand, FTIR data analyzed within the van't Hoff relationship yielded the energy barriers for dissociation Ea ∼ 20.3 ± 2.1 and 12.4 ± 1.6 kJ/mol for 2EHOH and nBOH, respectively. Hence, there was almost a perfect agreement between the values of Ea estimated from dielectric and FTIR studies for the 2EHOH, while some notable discrepancy was noted for the second alcohol. A quite significant difference in the activation barrier of dissociation indicates that there are probably supramolecular clusters of varying geometry or a ring-chain-like equilibrium is strongly affected in both alcohols. Nevertheless, our analysis showed that the association/dissociation processes undergoing within nanoassociates are one of the main factors underlying the molecular origin of the Debye process, supporting the transient chain model.

Abstract
INTRODUCTION
Pulmonary arterial hypertension (PAH) is a rare, progressive disease with poor prognosis. Stress echocardiography (SE) gives an important data on hemodynamic response to exercise. In patients with PAH SE may be useful for the diagnosis and risk assessment but data are lacking.
AIM OF STUDY
The aim of the study was to analyze exercise-induced response of right heart function and pulmonary artery pressure in patients with PAH.
MATERIALS AND METHODS
Study group consisted of 15 hemodynamically stable patients, 9 women, aged 22-73 (median- 50), diagnosed with PAH treated at Cardiology Department. The patients were subjected to stress echocardiography on supine cycloergometer and underwent assessment before and at peak-exercise. Moreover the standard parameters of clinical assessment: NT-proBNP, WHO functional class, and 6-minute walk test were analyzed.
RESULTS
Nine patients were in WHO class III, 4 of them- WHO class II and 2- WHO class I. The median NT-proBNP concentration was 169.3 (IQR 151.2-989.5) pg/ml. 6-Minute Walk Test distance was 455 (428-489) meters. The median workload was 75 (IQR 50-100) Watts and it was the median 54% (IQR 37-62%) of predicted.
The echocardiographic parameters assessed in SE at rest and shortly after peak-exercise revealed that RV systolic volume did not significantly differ: 70 (49.8-112.3) vs 71.5 (36.6-110) ml, p = 0.3. Right atrial area decreased from median 21.9 (17.4-27.3) to 19.8 (16.4-22.1) cm2, p = 0.05, whereas right atrial volume did not significantly changed - 80 (47.5-99.5) vs 68 (47.3-78.8) ml, p = 0.13. Further, shortly after exercise tricuspid regurgitation peak gradient (TRPG) significantly increased - 43 (25-76.5) vs 71 (50.5-102) mmHg, p = 0.002.
CONCLUSIONS
In stable PAH patients supine SE is feasible. Even in advanced WHO functional classes patients were able to exercise. Among echocardiographic parameters TRPG reflecting systolic pulmonary artery pressure showed the biggest difference between baseline and peak-exercise values. SE and seems to be a valuable tool in PAH patients’ assessment.

Abstract
Abstract
The first national registry of patients (pts) with PAH-CHD, predominantly with Eisenmenger Syndrome (ES), treated within national program was conducted. We studied clinical and echocardiographic characteristics of a group of adult patients including current therapy profile and mortality.
A multicenter observational study (snapshot registry) was conducted under auspices of Polish Cardiac Society, including pts with PAH-CHD, identified in centers, that treated > 5 pts in the first 10 years of therapeutic program (2008-2018). This analysis included 322 pts (70 deceased), mean age 42 ± 2 years, 65% females. The registry included patients meeting the criteria of the Eisenmenger syndrome in echocardiography (right-left or aligned leak). The living patients were divided into 2 groups: Gr.1 (n = 227) – uncorrected and Gr.2 (n = 25) - after correction of the heart disease.
The average age in Gr.1 was 40 ± 2 years, in Gr.2 40 ± 6 years. The majority were women (68% and 62%). There was no significant differences for mean duration of treatment in groups: 60 ± 12 months vs. 66 ± 6 months (p = 0.42). Both groups didn’t differ in terms of clinical data, i.e. 6MWT 417 ± 50 m vs. 384 ± 15 m;p = 0.15, NT-proBNP level 869 ± 470 pg/ml vs. 901 ± 212 pg/ml;p = 0.57. There was no significant differences for mean LVd in groups: 41,24 mm [12-82] vs. 44,25 mm [30-55]. Mean LVEF was good (60% in gr.1 vs. 57% in gr.2). Mean TAPSE was slightly better in Gr.1: 19,36 mm vs. 17,09 mm. Pericardial effusion were present in almost 15% pts from Gr.1 and less than 1% pts from Gr.2.
Pts after correction were mostly in the II WHO FC, and those uncorrected in the II/III WHO FC. Pts from Gr.2 were more likely to receive polytherapy (60% vs. 47%). ERA were the most commonly used (near 90%).
The most common heart defect was VSD (46% in Gr.1 vs. 32% in Gr.2). Mortality was 22% in entire period, i.e. annual mortality rate of 2.2%. In the group of dead pts women accounted for 74%, the average age was 49 ± 4 years and mean length of treatment was 42 ± 13 months. About 9% of pts from this group had heart defect correction in the past. Monotherapy (66%) predominated among the deceased, mainly using ERA (77%). Pts receiving combination therapy had a longer survival (p = 0.04). It isn’t known whether this result confirms the greater effectiveness of such treatment, as some patients couldn’t wait until the polytherapy became possible within the framework of the Drug Program. Among the deceased, the most common heart disease was ASD (30%), slightly less VSD (29%).
In this first national snapshot registry we documented improving prognosis in PAH-CHD under specific therapies. No differences were present in the length of therapy, clinical data and quality of life depending on whether or not correction surgery was performed. Post-correction pts more often received a polytherapy. The annual mortality in this population is small estimated just over 2%. Targeted combination therapy may contribute to better survival.

Abstract
Abstract
Background
Right ventricular (RV) function is a major determinant of survival in patients with pulmonary arterial hypertension (PAH). The concept of coupling mainly refers to the relationship between ventricular contractility and afterload. In advanced PAH, to maintain cardiac output, RV dilates and the uncoupling occurs with wall stress and increased metabolic demand. We previously confirmed that impaired RV function is associated with increased glucose uptake of RV myocytes estimated by PET, which marks patients with worse prognosis.
Purpose
Whether echocardiographic approach of coupling parameters in PAH patients has relationship with RV metabolic alterations.
Methods
Twenty-six stable PAH patients (mean age 49.92 ± 15.94 years) and sixteen healthy subjects (control group) were enrolled into the study. The TAPSE, reflecting RV contractility, was obtained by mono-dimensional echo in standard technique. The echo estimation of the sPAP was reflecting RV afterload. Ventricular-arterial coupling was evaluated by the ratio between those two parameters. All PAH patients had also right heart catheterization (RHC) and PET performed during baseline visit. Heart glucose metabolism was assessed with fluorodeoxyglucose (FDG) as a tracer in PET. Its uptake was quantified as mean standardized uptake value (SUV) for both left ventricle (LV) and RV. Mean follow-up time of this study was 16.6 ± 7.5 months and the clinical end-point (CEP) was defined as death or clinical deterioration.
Results
Most of enrolled patients were in the WHO functional Class III (61%, 16). There were significant correlations between echo-derived hemodynamic parameters and RHC-derived values e.g. emPAP vs mPAP (RHC), r = 0.86, p < 0.001. Echo-estimated RV ventricular-arterial coupling parameter (TAPSE/sPAP) was 0.35 ± 0.20 in PAH group and 1.51 ± 0.22 in control group, p < 0.001. Mean SUV RV/LV ratio was 1.03 ± 0.68 in PAH group and 0.19 ± 0.08 in controls, p < 0.005.
Echo-derived TAPSE/sPAP significantly correlated with hemodynamic parameters from RHC – cardiac output and pulmonary vascular resistance. Interestingly, we also observed significant correlations of TAPSE/sPAP with glucose uptake in PET - SUV RV as well as with SUV RV/LV (r=-0.63, p = 0.0006; r=-0.50, p = 0.0009), confirming higher metabolic demand in uncoupled heart in case of PAH.
Furthermore, patients who reached CEP (n = 15, 57%) had a significantly lower TAPSE/esPAP ratio (0.29 ± 0.17 vs 0.43 ± 0.21, p = 0.04) and higher SUV RV/LV (1.39 ± 0.79 vs 0.55 ± 0.45, p = 0.01). ROC analysis revealed significant cut-off value of TAPSE/esPAP in predicting CEP (AUC 0.72 (95% CI 0.52-0.92), p = 0.03). Patients with TAPSE/esPAP lower than 0.25 mm/mmHg had worse prognosis, log-rank test, p = 0.001 (Figure 1).
Conclusions
Simple echocardiographic parameter reflecting RV coupling (TAPSE/esPAP) related to altered myocardium metabolism in PAH may predict outcome in patients with PAH.

Abstract
Pullulan and chitosan are biocompatible polysaccharides obtained from natural sources with many biomedical applications. Cationically modified polymers, such as chitosan and pullulan after covalent attachment of glycidyltrimethylammonium chloride (GTMAC), showed beneficial biological properties. In the present study, it was clearly demonstrated and confirmed that both cationically modified polysaccharides (chitosan-GTMAC and pullulan-GTMAC) have the antiatherosclerotic potential by inhibition of atherosclerotic plaque development and controlling the expression of genes involved in lipid metabolism. It has also been shown that the cationically modified chitosan (HTCC) at a dose of 200 mg/kg b.w./day in male apoE-knockout mice acted as hypolipidaemic agent. It was observed that a statistically significant decrease in low-density lipoprotein (LDL) cholesterol level by 32% occurred under the influence of HTCC at a dose of 200 mg/kg b.w./day after 16 weeks of the experiment compared to the control group of apoE(-/-) mice. Moreover, under the influence of cationically modified chitosan administered orally to female apoE-knockout mice at a dose of 300 mg/kg b.w./day for 18 weeks a statistically significant reduction by 33% in the area of atherosclerotic plaque was observed compared to the control group, i.e., apoE-knockout mice whose diet was not supplemented with the cationically modified polysaccharide. Current in vivo studies connected with cationically modified pullulan showed a statistically significant 22% reduction of the area of atherosclerotic plaque in the apoE(-/-) mice fed with a feed containing Pull-GTMAC at a dose of 500 mg/kg b.w./day for 18 weeks in comparison to the control group of apoE-knockout mice. In the in vitro studies it was also shown that cationically modified chitosan acted therapeutically by reduction of the level of the expression of human 3-hydroxy-3-methylglutaryl-CoA reductase (human HMG-CoAR) after 24 hours of incubation with HepG2 cells. However, cationically modified pullulan did not show this effect in the experiment on HepG2 cell line. On the other hand, Pull-GTMAC caused a statistically significant increase in insulin induced gene 1 (INSIG1) expression and increase in mRNA level of LDL receptor in brown fat tissue of female apoE-knockout mice after oral administration with feed at a dose of 300 mg/kg b.w./day for 18 weeks in comparison to the control group of apoE(-/-) mice, that was crearly demonstrated the effect of cationically modified pullulan on the expression of lipid metabolism genes in in vivo conditions. In the present article we have shown for first time that cationically modified pullulan and chitosan have some similarities in their antiatherogenic action but there are also some minor differences in mechanism of their effect on lipid metabolism.

Abstract
Chronic inflammation is a critical feature of obesity in the development of myocardial dysfunction. The observations that interleukin-6 (IL-6) is implicated in lipid and glucose homeostasis as well as its connection with the pathogenesis of insulin resistance might suggest the involvement of this cytokine in metabolic disorders of the failing heart. In the present study we aimed to assess the effects of IL-6 ablation in mice fed with normal and high fat diet on the myocardial expression of glucose and fatty acid transporting proteins, and to evaluate the paralleled alterations in lipid content. We demonstrated that mice devoid of IL-6 exert reduced glucose transporter type 4 (GLUT-4) expression (-26%) and plasma membrane abundance (-43%), with no effect on glucose transporter type 1 (GLUT-1) content. Although there were no significant alterations in fatty acid translocase (FAT/CD36) and plasma membrane-associated fatty acid-binding protein (FABPpm) levels, we revealed a substantial decline in intramyocardial triacylglycerol level (-49%). Challenging of IL-6 knockout (KO) mice with high fat diet evoked an increase in FAT/CD36 expression (+19%) concomitantly with a trend for its reduced amount in plasma and mitochondrial membranes. Additionally, an increase in triacylglycerol level (+56%) was noticed, simultaneously with elevated content of saturated (+62%), monounsaturated (+69%) and polyunsaturated (+38%) fatty acids in this lipid fraction. The presented data reflect different roles of IL-6 in cardiomyocytes under selected conditions (i.e., normal and excessive lipid supply).

Abstract
In this paper, the molecular dynamics of a series of ester derivatives of ibuprofen (IBU), in which the hydrogen atom from the hydroxyl group was substituted by the methyl, isopropyl, hexyl, and benzyl moieties, has been investigated using Broadband dielectric (BD), Nuclear magnetic resonance (NMR), and Raman spectroscopies. We found that except for benzyl IBU (Ben-IBU), an additional process (slow mode, SM) appears in dielectric spectra in all examined compounds. It is worth noting that this relaxation process was observed for the first time in non-modified IBU (a Debye relaxation). According to suggestions by Affouard and Correia [J. Phys. Chem. B. 114, 11397 (2010)] as well as further studies by Adrjanowicz et al. [J. Chem. Phys. 139, 111103 (2013)] on Met-IBU, it was attributed to synperiplanar-antiperiplanar conformational changes within the molecule. Herein, we have shown that with an increasing molecular weight of the substituent, the relaxation times of the SM become longer and its activation energy significantly increases. Moreover, this new relaxation mode was found to be broader than a simple Debye relaxation in Iso-IBU and Hex-IBU. Additional complementary NMR studies indicated that either there is a significant slowdown of the rotation around the O=C-O-R moiety or this kind of movement is completely suppressed in the case of Ben-IBU. Therefore, the SM is not observed in the dielectric loss spectra of this compound. Finally, we carried out isothermal experiments on the samples which have a different thermal history. Interestingly, it turned out that the relaxation times of the structural processes are slightly shorter with respect to those obtained from temperature dependent measurements. This effect was the most prominent in the case of Hex-IBU, while for Ben-IBU, it was not observed at all. Additional time-dependent measurements revealed the ongoing equilibration manifested by the continuous shift of the structural process, until it finally reached its equilibrium position. Further Raman investigations showed that this effect may be related to the rotational/conformational equilibration of the long hexyl chains. Our results are the first ones demonstrating that the structural process is sensitive to the conformational equilibration occurring in the specific highly viscous systems.

Abstract
Comprehensive FTIR studies on the progress of mutarotation in d-fructose mixed with maltitol have been carried out over a wide range of temperatures, both above and below the glass transition temperature Tg. In addition to the analysis of single bands, we have developed a completely new approach considering the full spectral range to follow the overall progress of the reaction. We have found that at the calorimetric Tg, there is a clear change in the temperature dependence of constant rates. The activation barrier for mutarotation changes from around 59 kJ mol-1 (the supercooled state) to around 249 kJ mol-1 (the glassy state). This dramatic variation in the activation barrier is consistent with the change in the mechanism of this specific chemical conversion, as theoretically considered by Wlodarczyk et al. [Phys. Chem. Chem. Phys., 2014, 16, 4694-4698]. Alternatively, it can also be connected to the change in the viscosity of the sample. Additionally, we investigated the relationship between constant rates (k) of mutarotation, structural relaxation times (τα), and dc conductivity (σdc) above and below the glass transition temperature. It was found that there was a linear correlation between all these quantities; they scale with various exponents changing at Tg. Our results also indicate that a single activation barrier might not be sufficient to describe the mutarotation process.

Abstract
In this letter, we reported thorough the structural and molecular dynamics studies on 1,6-anhydro-β-D-glucose, the second compound reported so far that is capable to form rotator and supercooled liquid phases. In contrast to the data presented for ethanol, temperature dependences of structural dynamics in both phases are very comparable. On the other hand, X ray measurements revealed unusually long range ordering/correlations between molecules in the ODIC (d ≈ 95 Å) and supercooled phases (d ≈ 30-40 Å) of this carbohydrate. Our consideration clearly demonstrated that the interplay between length scales of static range ordering and dynamical heterogeneities as well as internal molecular arrangement seem to be the key to understanding the molecular dynamics of different materials characterized by varying degree of disorder in the vicinity of the glass transition temperature.

Abstract
Broadband dielectric spectroscopy (BDS) and differential scanning calorimetry (DSC) were applied to investigate the molecular dynamics and phase transitions in binary mixtures composed of naproxen (NAP) and acetylated saccharides: maltose (acMAL) and sucrose (acSUC). Moreover, the application of BDS method and optical microscopy enabled us to study both crystallization kinetics and crystal growth of naproxen from the solid dispersions with the highest content of modified carbohydrates (1:5wt ratio). It was found that the activation barriers of crystallization estimated from dielectric measurements are completely different for both studied herein mixtures. Much higher Ea (=205kJ/mol) was obtained for NAP-acMAL solid dispersion. It is probably due to simultaneous crystallization of both components of the mixture. On the other hand, lower value of Ea in the case of NAP-acSUC solid dispersion (81kJ/mol) indicated, that naproxen is the only crystallizing compound. This hypothesis was confirmed by X-ray diffraction studies. We also suggested that specific intermolecular dipole-dipole interactions between active substance and excipient may be an alternative explanation for the difference between activation barrier obtained for NAP-acMAL and NAP-acSUC binary mixtures. Furthermore, optical measurements showed that the activation energy for crystal growth of naproxen increases in binary mixtures. They also revealed that both excipients: acMAL and acSUC move the temperature of the maximum of crystal growth towards lower temperatures. Interestingly, this maximum occurs for nearly the same structural relaxation time, which is a good approximation of viscosity, for all samples. Finally, it was also noticed that although naproxen crystallizes to the same polymorphic form in both systems, there are some differences in morphology of obtained crystals. Thus, the observed behavior may have a significant impact on the bioavailability and dissolution rate of API produced in that way.

Abstract
Pullulan is a biocompatible polysaccharide obtained from black, yeast-like fungus Aureobasidium pullulans. This polymer is used to deliver various substances to the liver because of its specificity for this organ. Pullulan is internalized into hepatocytes in the process of asialoglycoprotein receptor mediated endocytosis. Recently, by reaction with glycidyltrimethylammonium chloride (GTMAC) we have successfully synthesized a cationically-modified pullulan (Pull-GTMAC). Pull-GTMAC exhibits some unique beneficial effects not found for its native counterpart. In this article we have reported for the first time that Pull-GTMAC administered orally to apoE-knockout mice (murine model of atherosclerosis) at a dose of 300 mg/kg b.w./day for 18 weeks showed anti-atherosclerotic activity reducing the area of atherosclerotic plaque. We have also found that Pull-GTMAC at a dose of 300 mg/kg b.w./day increases both the average daily mass of feces and the average number of droppings excreted by apoE(-/-) mouse in relation to the control sample derived from the mice fed with feed without the tested compound. However, the raw fat content in the feces of apoE-knockout mice was decreased in the group fed with the diet containing Pull-GTMAC towards control group of animals. Pull-GTMAC caused also statistically significant increase of mRNA level for LDL receptor in the apoE(-/-) mice liver after administration at a dose of 300 mg/kg/b.w./day for 18 weeks. However, the compound had no impact on lipid profile in serum of the tested mice. What is more, the studies on HepG2 cell line indicated an antiproliferative potential of cationically modified pullulan after 24 hour and 48 hour of incubation with the polysaccharide. In this paper we have shown for first time that cationically modified pullulan has antiatherogenic potential and influences on lipid metabolism.

Abstract
The aim of this work is to analyze in detail the effect of small hydrogen bonding (HB) structures and enantiomeric composition on the dynamics of glass-forming liquid ketoprofen. For that purpose dielectric relaxation, rheological and NMR studies were performed. Investigated samples are racemic ketoprofen, a single enantiomer of ketoprofen and a racemic ketoprofen methyl ester with no tendency to form HB dimers. The combination of complementary experimental techniques enables us to show that macroscopic viscosity η and α-relaxation time τα have nearly the same temperature dependencies, whereas the relation between the viscosity (or molecular reorientation) and the translational self-diffusion coefficient violates Stokes-Einstein law already at high temperature. Additionally, based on dielectric relaxation studies performed on increased pressure we were able to identify similarities and key differences in the supercooled liquid dynamics of investigated materials affected by their tendency to form intermolecular hydrogen bonds. This includes the effect of pressure on the glass transition temperature Tg, changes in the fragility parameter m and activation volume ΔV, the role of thermal energy and density fluctuations in governing the viscous liquid dynamics (Ev/Ep ratio). Finally, we have also demonstrated that the dynamic behaviour of a single enantiomer and the racemic mixture of the same compound are very much alike. Nevertheless, some slight differences were observed, particularly in the τα(T) dependencies measured in the vicinity of glass transition both at ambient and elevated pressure.

Abstract
High pressure dielectric studies on the H-bonded liquid D-glucose and Orientationally Disordered Crystal (ODIC) 1,6-anhydro-D-glucose (levoglucosan) were carried out. It was shown that in both compounds, the structural relaxation is weakly sensitive to compression. It is well reflected in the low pressure coefficient of the glass transition and orientational glass transition temperatures which is equal to 60 K/GPa for both D-glucose and 1,6-anhydro-D-glucose. Although it should be noted that ∂Tg(0)/∂p evaluated for the latter compound seems to be enormously high with respect to other systems forming ODIC phase. We also found that the shape of the α-loss peak stays constant for the given relaxation time independently on the thermodynamic condition. Consequently, the Time Temperature Pressure (TTP) rule is satisfied. This experimental finding seems to be quite intriguing since the TTP rule was shown to work well in the van der Waals liquids, while in the strongly associating compounds, it is very often violated. We have also demonstrated that the sensitivity of the structural relaxation process to the temperature change measured by the steepness index (mp) drops with pressure. Interestingly, this change is much more significant in the case of D-glucose with respect to levoglucosan, where the fragility changes only slightly with compression. Finally, kinetics of ODIC-crystal phase transition was studied at high compression. It is worth mentioning that in the recent paper, Tombari and Johari [J. Chem. Phys. 142, 104501 (2015)] have shown that ODIC phase in 1,6-anhydro-D-glucose is stable in the wide range of temperatures and there is no tendency to form more ordered phase at ambient pressure. On the other hand, our isochronal measurements performed at varying thermodynamic conditions indicated unquestionably that the application of pressure favors solid (ODIC)-solid (crystal) transition in 1,6-anhydro-D-glucose. This result mimics the impact of pressure on the crystallization of fully disordered supercooled van der Waals liquids.

Abstract
Dielectric relaxation studies for model glass-forming liquids confined to nanoporous alumina matrices were examined together with high-pressure results. For confined liquids which show the deviation from bulk dynamics upon approaching the glass transition (the change from the Vogel-Fulcher-Tammann to the Arrhenius law), we have observed a striking agreement between the temperature dependence of the α-relaxation time in the Arrhenius-like region and the isochoric relaxation times extrapolated from the positive range of pressure to the negative pressure domain. Our finding provides strong evidence that glass-forming liquid confined to native nanopores enters the isochoric conditions once the mobility of the interfacial layer becomes frozen in. This results in the negative pressure effects on cooling. We also demonstrate that differences in the sensitivity of various glass-forming liquids to the "confinement effects" can be rationalized by considering the relative importance of thermal energy and density contributions in controlling the α-relaxation dynamics (the E(v)/E(p) ratio).

Abstract
Abstract
Type A complete spinach chloroplasts (photosynthetic control ratio ≅ 5) were frozen in liquid nitrogen, in the presence or absence of 50 percent glycerol (v/v). By considering five parameters related to the non cyclic electron transfer in the light (oxidant : K-ferricyanide) it was shown that the uncoupling due to freezing and thawing was partially prevented by glycerol. However glycerol was responsible for a slight uncoupling in fresh chloroplasts. The clearest uncoupling effect of freezing, and chiefly of glycerol, concerned the inhibition of the electron flow which follows the stimulation caused by a limiting quantity of ADP (state 4).
The relative decrease of the photosynthetic control and of related parameters due to the use of this method of preservation, has to be balanced with the improved homogeneity and convenience resulting from it.

Abstract
Chitosan is biocompatible polymer obtained from chitin, the building component of the crustacean shells. In this paper we make an attempt to review the current state of knowledge on some biological effects of chitosan in comparison with those of cationically modified chitosan, N-(2-hydroxypropyl)-3-trimethylammonium chitosan chloride (HTCC) that was recently synthetized by us by covalent attachment of glycidyltrimethylammonium chloride (GTMAC). Biological effects of HTCC and non-modified polymer are very similar. However, HTCC shows some unique beneficial properties which have not been found in its non-modified counterpart. One such example is that HTCC has the ability to bind heparin at physiological pH. HTCC having the degree of substitution almost 63.6% is easily absorbed within 1 hour after oral administration as found in C57BL/6j mice using FITC-labeled polymer. HTCC is distributed to lung, heart, and kidneys. HTCC stimulates and enhances blood platelet aggregation and decreases erythrocyte deformability (RBC). Moreover, HTCC seems to decrease both plasma total cholesterol level and LDL-cholesterol level in apoE-knockout mice fed with a diet containing HTCC. HTCC possibly down-regulates the HMG-CoAR mRNA level after 24 hour incubation with HepG2 cells in vitro.

Abstract
PURPOSE To demonstrate a very effective and easy way of stabilization of amorphous indomethacin (IMC) by preparing binary mixtures with octaacetylmaltose (acMAL). In order to understand the origin of increased stability of amorphous system inter- and intramolecular interactions between IMC and acMAL were studied. METHODS The amorphous IMC, acMAL and binary mixtures (IMC-acMAL) with different weight ratios were analyzed by using Dielectric Spectroscopy (DS), Differential Scanning Calorimetry (DSC), Raman Spectroscopy, X-ray Diffraction (XRD), Infrared Spectroscopy (FTIR) and Quantitative Structure-Activity Relationship (QSAR). RESULTS Our studies have revealed that indomethacin mixed with acetylated saccharide forms homogeneous mixture. Interestingly, even a small amount of modified maltose prevents from recrystallization of amorphous indomethacin. FTIR measurements and QSAR calculations have shown that octaacetylmaltose significantly affects the concentration of indomethacin dimers. Moreover, with increasing the amount of acMAL in the amorphous solid dispersion molecular interactions between matrix and API become more dominant than IMC-IMC ones. Structural investigations with the use of X-ray diffraction technique have demonstrated that binary mixture of indomethacin with acMAL does not recrystallize upon storage at room temperature for more than 1.5 year. Finally, it was shown that acMAL can be used to improve solubility of IMC. CONCLUSIONS Acetylated derivative of maltose might be very effective agent to improve physical stability of amorphous indomethacin as well as to enhance its solubility. Intermolecular interactions between modified carbohydrate and IMC are likely to be responsible for increased stability effect in the glassy state.

Abstract
Comprehensive molecular dynamics studies of vitrified and cryogrounded itraconazole (Itr) were performed at ambient and elevated pressure. DSC measurements yielded besides melting and glass transition observed during heating and cooling of both samples two further endothermic events at around T = 363 K and T = 346 K. The nature of these transitions was investigated using X-ray diffraction, broadband dielectric spectroscopy and Density Functional Theory calculations. The X-ray measurements indicated that extra ordering in itraconazole is likely to occur. Based on calculations and theory derived by Letz et al. the transition observed at T = 363 K was discussed in the context of formation of the nematic mesophase. In fact, additional FTIR measurements revealed that order parameter variation in Itr shows a typical sequence of liquid crystal phases with axially symmetric orientational order; i.e. a nematic phase in the temperature range 361.7 K to 346.5 K and a smectic A phase below 346.5. Moreover, dielectric measurements demonstrated that except for the structural relaxation process, there is also slower mode above the glass transition temperature in both vitrified and cryogrounded samples. We considered the origin of this mode taking into account DFT calculations, rod like shape of itraconazole and distribution of its dipole moment vectors. For the dielectric data collected at elevated pressure, evolution of the steepness index versus pressure was determined. Finally, the pressure coefficient of the glass transition temperature was evaluated to be equal to 190 K GPa(-1).

Abstract
The sugar specific mutarotation reaction in biologically important L-fucose and its enantiomer in the pure, anhydrous, supercooled liquid state has been studied. Kinetics measurements in the temperature range 313-328 K at ambient pressure have been performed by means of dielectric spectroscopy, a method widely used for studying the molecular dynamics of glass-forming liquids. The kinetic curves have been obtained by tracking the equilibration process in sugar melted and quenched to the desired temperature. Thereafter, an activation energy equal to Ea = 140 kJ mol(-1) for D-fucose and Ea = 123 kJ mol(-1) for L-fucose has been derived from the Arrhenius fit of temperature dependent rate constants. It was also shown that the kinetics curves at the lowest temperatures studied have sigmoidal shape, which was connected to the high concentration of furanosidic forms.

Abstract
Recently it was reported that upon mechanical milling of pure furosemide significant chemical degradation occurs (Adrjanowicz et al. Pharm. Res.2011, 28, 3220-3236). In this paper, we present a novel way of chemical stabilization amorphous furosemide against decomposing that occur during mechanical treatment by preparing binary mixtures with acylated saccharides. To get some insight into the mechanism of chemical degradation of furosemide induced by cryomilling, experimental investigations supported by density functional theory (DFT) computations were carried out. This included detailed studies on molecular dynamics and physical properties of cryoground samples. The main thrust of our paper is that we have shown that furosemide cryomilled with acylated saccharides forms chemically and physically stable homogeneous mixtures with only one glass transition temperature, Tg. Finally, solubility measurements have demonstrated that furosemide cryomilled with acylated saccharides (glucose, maltose and sucrose) is much more soluble with respect to the crystalline form of this active pharmaceutical ingredient (API).

Abstract
Dielectric, calorimetric, and x-ray diffraction measurements were carried out on α-, β-, and γ-cyclodextrins, which are cyclic saccharides built by, respectively, six, seven, and eight glucose units connected via glycosidic linkage. Differential scanning calorimetry measurements indicated that each carbohydrate has a melting temperature located much above the temperature at which thermal decomposition begins. Moreover, calorimetric data revealed that it is possible to completely dehydrate each cyclodextrin by annealing them above 413 K. Unfortunately, it is impossible to obtain amorphous forms of cyclodextrin by simple cooling of the melt. Thus, a solid state amorphization method has been applied. X-ray diffraction studies demonstrated that by ball milling at room temperature we are able to obtain completely amorphous cyclodextrins. Finally, dielectric measurements were carried out to probe molecular dynamics in the amorphous state of cyclodextrins. It was found that there is only one relaxation process in amorphous hydrated cyclodextrins, while in dried samples two secondary relaxations are present. Moreover, we have shown that water has an enormous effect on the dynamics of both relaxation modes, i.e., with increasing content of water, the activation energy of the slow mode decreases, while that evaluated for the fast mode increases. We were not able to follow the dynamics of the structural relaxation process, because glass transition temperatures of amorphous cyclodextrins were found to lie above thermal degradation points.
