Abstract:
Background: Psoriasis is a chronic immune-mediated skin disease in which systemic inflammation plays an important role in its pathogenesis. In recent years, the neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-monocyte ratio (NMR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) were shown to be important indicators of inflammation. This study aimed to investigate the NLR, NMR, PLR, and SII levels in psoriasis patients treated with biological agents. Method: Clinical and biochemical data of 209 patients who received systemic therapy for psoriasis were obtained by retrospectively reviewing their medical records. The NLR, NMR, PLR, and SII values were calculated from the hemogram values of the patients. Results: In the third month of follow-up, the mean CRP, NLR, NMR, PLR, and SII values were significantly decreased compared with the baseline values. The SII values showed strong positive correlations with the NLR, NMR, and PLR. Adalimumab, etanercept, and infliximab, which are TNF-α blockers, were observed to be more effective on the PLR and NLR, and especially the NMR. Conclusions: The NLR, NMR, PLR, and SII, which are data derived from routine blood tests, can be used in the monitoring of the treatment of psoriasis, especially with TNF-α blockers.

Abstract:
This study examines the criminality of noninstitutionalized mentally retarded (NIMR) men and women in a Swedish birth cohort composed of 15,117 participants followed from before birth to age 30. NIMR participants were compared with participants who had never been placed in a special class or in an institution for the mentally retarded or admitted to a psychiatric ward (NMR). NIMR participants were more likely than NMR participants to have been convicted for a criminal offense before age 30 and for a violent offense. NIMR offenders had been convicted, on average, for the same number of offenses as NMR offenders. Among the NIMR offenders, 71% of men and only 43% were first convicted before the age of 18. For both NIMR men and women, childhood conduct problems were found to be associated with adult criminality.

Abstract:
Abstract Background Determining disease activity in ulcerative colitis (UC) patients is important in order to reduce surgery rate and mortality. Colonoscopy has the disadvantage of being invasive, time consuming and expensive. Several laboratory markers have been proposed in order to evaluate UC disease activity. Methods The aim is to investigate the utility of neutrophil-lymphocyte ratio (NLR), neutrophil-monocyte ratio (NMR), and lymphocyte-monocyte ratio (LMR) in differentiating active UC from UC in remission. This is a prospective study carried out at a hospital center in Albania, from 2019–2020. Demographic and endoscopic data along with complete blood counts were collected for each UC patient. Based on Mayo score system, patients were classified as active UC (total Mayo score >2 points) and UC in remission (total Mayo score ≤ 2 points). Pearson correlation coefficient was used to analyze associations between parameters. The sensitivity, specificity, and cut-off values were assessed using a receiver operating characteristic curve analysis. Results 65 UC patients, with a mean age of 45.05 ± 15.5 (16–85) years, of whom 52.3% were females and 47.7% males, were enrolled in this study. 21.4% were in remission and 63.4% were classified as active UC disease. We found a positive correlation between NLR, NMR and disease activity [(r=0.295, p=0.002); (r=0.241, p=0.011) respectively]. NLR and NMR were also significantly higher in active disease group compared to UC in remission (p=0.016 and p=0.03 respectively). ROC analyses revealed that NLR (AUC=0.664, 95% CI, 0.557–0.772) and NMR (AUC=0.644, 95% CI, 0.531–0.756) are satisfactory in differentiating active UC from UC remission patients. A NLR cutoff value of 2.1 had a sensitivity of 60% and specificity of 61% for active UC, while a NMR cutoff value of 12.2 had a sensitivity of 63% and a specificity of 61% for active UC. We didn’t found any correlation between LMR and disease activity Conclusion This study shows that NLR and NMR are significantly associated with active UC disease. Given the fact that complete blood count is widely available and inexpensive, NLR and NMR may play a role in differentiating active UC from UC in remission.

Abstract:
Although the potential relationship between headaches, particularly migraine, and peripheral inflammatory markers (PIMs) has been investigated, it is unclear whether PIMs are involved in the pathogenesis of migraine or can differentiate it from non-migraine headaches (nMHs). Using 10 years of data from the Smart Clinical Data Warehouse, patients who visited the neurology outpatient department (OPD) within 30 days after visiting the emergency room (ER) for headaches were divided into migraine and nMH groups, the PIMs were compared including the neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte (PLR) ratios, and neutrophil-to-monocyte ratio (NMR). Of the 32,761 patients who visited the ER for headaches, 4005 patients visited the neurology OPD within 30 days. There were significant increases in the NLR, MLR, and NMR, but a lower PLR in the migraine and nMH groups than the controls. The NMR was significantly higher in the migraine than the nMH group. A receiver operating characteristic curve analysis showed that the ability of the NLR and NMR to differentiate between migraine and nMHs was poor, whereas it was fair between the migraine groups and controls. The elevated PIMs, particularly the NLR and NMR, during headache attacks in migraineurs suggest that inflammation plays a role in migraine and PIMs may be useful for supporting a migraine diagnosis.

Abstract:
The suitability of different process spectrometry techniques has been assessed, in terms of calibration requirements, accuracy, and precision, for the at-line monitoring of the sulfonation of fluorobenzene. Partial least-squares (PLS) calibration was required to analyze the spectra obtained by NIR spectrometry and low-field (29.1 MHz) 1H NMR spectrometry. The low-field (27.4 MHz) 19F NMR spectra contained well-resolved signals for the three fluorine containing compounds and univariate calibration was adequate. The Raman spectra of two of the compounds exhibited fluorescence and so this technique was not considered suitable for monitoring the reaction. The accuracy of the results obtained using univariate analysis of the 19F NMR data and PLS analysis of NIR data were comparable (average % error of 3.5 and 2.9%, respectively, for concentrations >0.5 mol dm−3 and 11.3 and 11.1%, respectively, for <0.5 mol dm−3). The least accurate results were obtained using PLS analysis of low-field 1H NMR data, as the spectra of two of the components were too similar. For concentrations >0.05 mol dm−3, the most precise results were obtained with PLS analysis of NIR data (average RSD of 1.6%), although the precision of the results obtained using univariate analysis of 19F NMR data was still good (average RSD of 3.7%).

Abstract:
Abstract This study shows the use of time-domain (TD)-NMR transverse relaxation (T2) data and chemometrics in the nondestructive determination of fat content for powdered food samples such as commercial dried milk products. Most proposed NMR spectroscopy methods for measuring fat content correlate free induction decay or echo intensities with the sample's mass. The need for the sample's mass limits the analytical frequency of NMR determination, because weighing the samples is an additional step in this procedure. Therefore, the method proposed here is based on a multivariate model of T2 decay, measured with Carr-Purcell-Meiboom-Gill pulse sequence and reference values of fat content. The TD-NMR spectroscopy method shows high correlation (r = 0.95) with the lipid content, determined by the standard extraction method of Bligh and Dyer. For comparison, fat content determination was also performed using a multivariate model with near-IR (NIR) spectroscopy, which is also a nondestructive method. The advantages of the proposed TD-NMR methodare that it (1) minimizes toxic residue generation, (2) performs measurements with high analytical frequency (a few seconds per analysis), and (3) does not require sample preparation (such as pelleting, needed for NIR spectroscopy analyses) or weighing the samples.

High-resolution solid-state 13C NMR and NIR diffuse reflectance spectra were obtained on microcrystalline and “noncrystalline” celluloses. Particle sizes and relative crystallinity were confirmed by scanning electron microscopy and MIR transmission spectroscopy, respectively. The results showed that NMR is more sensitive to order changes and less sensitive to particle size. NIR reflectance, on the other hand, is very sensitive to particle size changes and essentially insensitive to differences in order.

Abstract:
Nanocapsules are generally considered as spherical, hollow structures. Important potential applications are pharmaceutically related such as drug targeting and controlled release. Typically, the capsules consist of a polymeric wall, filled with an oil which can dissolve lipophilic agents. To enable a stable aqueous dispersion, the capsule surface is covered by an amphiphilic surfactant. Nanocapsule-dispersions were investigated by means of solid-state nmr. Cross polarization experiments revealed the morphology of the polymeric wall. Further, the spin-lattice relaxation times for the proton magnetization in the rotating frame were studied under direct excitation as well as under cross polarization conditions. Based on the results, a special mechanism of cross polarization is proposed, initiated by a temporary adsorption of mobile oil- and surfactant-molecules to the more rigid capsule surface. - Nanokapseln sind sphärische, hohle Objekte, die in der Medizin als gewebespzifische Wirkstoff-Träger-Systeme eingesetzt werden sollen.

Abstract:
The phase-encoded method of NMR flow imaging is examined in detail. The motion of isochromatic groups in the direction of suitably balanced magnetic field gradients will give a phase change in the NMR signal directly proportional to the velocity, acceleration, or higher derivative of position, dependent upon the form of the field gradient. If a simple bipolar pulse is used then the phase change, for isochromats moving with constant velocity, will be proportional to the velocity. If two such pulses are placed back to back then the phase change is proportional to the acceleration. The motion of isochromats in the magnetic field gradients used for imaging will also cause phase changes. These effects are considered, and simple methods of reducing them presented. Phase errors due to main field inhomogeneity are shown to be eliminated by a simple phase difference technique. In this two image data sets having different flow sensitivities are obtained, and the phase difference between them calculated. Velocity images were obtained using this technique, both by the manipulation of the frequency-encoding and selection gradients, and by the insertion of bipolar pulses in the imaging sequence. Acceleration images were also produced by adding double bipolar pulses to the imaging sequence. Both spin-echo and field-echo sequences were used. Field-echo sequences were shown to be superior for high velocities, particularly when the direction of flow is through the slice, otherwise spin-echo sequences were preferred. The Fourier imaging of velocity is also examined, and images presented. This technique is only considered to be useful for projective imaging, where it is shown to have an SNR advantage over established methods. Using two specially designed phantoms the accuracy of all these techniques is shown to be within 5%.

Abstract:
During the last decades, the interest of chemistry toward increasingly sophisticated processes has grown exponentially. As a consequence, the evolution of the systems under investigation has been necessarily paired with the development of modern methodologies capable of handling the enormous amount of data stemming from samples of great complexity. Among the many examples in the literature, one of the biggest ongoing challenges is the analysis of mixtures, from reaction crude extracts to biological fluids like blood and urine. Indeed, chromatography has been - and still remains - one of the primary methods adopted to reduce the complexity of a multi-analyte system. Nonetheless, one intrinsic problem of the chromatographic approach is its inability to identify unknown molecules, and hyphenated techniques (mostly based on mass spectroscopy) have been developed just to overcome this stumbling block. On the other hand, Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful techniques for the investigation of organic compounds. NMR exploits an intrinsic property exhibited by some atomic nuclei -- the spin -- to acquire chemical and structural information through well-established experimental protocols, known as pulse sequences. In particular, solution-state NMR can boast a vast ensemble of procedures aimed at collecting detailed data about through bond connectivities (COSY, TOCSY, HSQC,...) or through space proximities (NOESY, ROESY,...). All these information are nothing less than fundamental for the structure determination of unknown compounds. Even tough this makes NMR spectroscopy largely appealing, the acquisition of such extensive information ultimately translates into detecting many signals at once, so that spectra interpretation can become a very challenging task. This is especially true when observing 1H resonances, which display a small dispersion in the frequency domain (about 12 ppm) and spectral crowding becomes consequently a serious problem. Not surprisingly, the situation becomes almost unmanageable when NMR is applied to the assay of mixtures, where the superposition of signals stemming from different species is virtually assured. Certainly, multidimensional NMR techniques can be useful for the interpretation of crowded single-molecule spectra, but they rapidly loose all their advantages as the number of components in the sample increases. As for chromatography, the advent of hybrid techniques like LC-NMR, where LC stands for Liquid Chromatography, has partly circumvented the aforementioned difficulties, yet at the cost of an expensive and dedicated instrumentation. In the context of mixture analysis, matrix-assisted NMR methodologies stand as an alternative to the various hyphenated techniques. They rely on the combination of NMR spectroscopy and an external agent added to the sample, which can be either a molecular or macromolecular species, or even a mesoscopic matrix. The aim of such matrices is to differentiate the signals of the various components, favouring their detection and characterisation. The present work is divided into three independent parts. The first two are dedicated to different subjects of matrix-assisted NMR. In particular, Part I is aimed at the understanding of the physical phenomena underlying signal broadening when a solid, stationary phase is used in Matrix-Assisted Diffusometry (MAD) NMR measurements. Part II focuses on nanoparticle-assisted NMR chemosensing, a technique where monolayer-protected gold nanoparticles are exploited to transfer magnetization to selected classes of analytes by means of the Nuclear Overhauser Effect. In this second part, different nanoparticle-assisted methodologies are presented and analysed, alongside with some strategies aimed at the enhancement of the sensitivity. Part III concerns the complete 1H-NMR characterisation of the atomically precise Au38(SBut)24 gold nanocluster, which can be considered as a prototypical nanoparticle. The Au38 core features four different symmetry-unique and equally populated binding sites for the grafting of the ligands that constitute the coating monolayer. Each binding site shows a distinct pattern of resonances, so that the overall 1H-NMR spectrum of the cluster is the result of the superposition of four independent subspectra. In this case, the full characterisation of the spectrum has been achieved through a combined NMR-MD (Molecular Dynamics) analysis.

Full text
Abstract:
The thesis extends the concept of Irreducible Spherical Tensor Operators to spin dynamics problems in Nuclear Magnetic and Quadrupole Resonance Spectroscopy. NQR and solid state NMR deal with spin systems which behave as effective single spins in many, pulsed experiments, or as multispin systems when the dipolar interactions among spins cannot be neglected. The thesis considers problems in both areas. New analytic results are derived in the thesis for pure NQR spectroscopy and for the effect of radiofrequency fields in the presence of electric quadrupolar interaction. Three-pulse experiments are proposed for a spin-5/2 system and quantitative calculations are done for the indirect detection of new observables. Attention is focussed on the usefulness of the full-spin density matrix in all these calculations. In addition the concept of multispin tensors is applied to a system of spin-1/2 nuclei with strong dipolar interactions. This leads to coupled differential equations for correlations among spins for which an iterative solution can be obtained. The solutions are discussed in relation to Free Induction Decay experiments available for $ sp{19}$F nuclei in CaF$ sb2$ crystal.

Abstract:
Dispersion remains, today, a highly topical subject. Our group has been interested in characterizing this phenomenon by pulsed-field-gradient NMR technique. Direct measurement of the dispersion coefficient can be done with a Pulsed Gradient Spin Echo (PGSE) sequence by assuming that the asymptotic regime is reached. In unsteady state, the propagator formalism is used. To better understand these measurements, the NMR experiment is modeled using a stochastic simulation (random walks) and compared with experimental results. The comparison is made for the simple case of Poiseuille flow in a circular tube (Taylor-Aris dispersion).
