Abstract (sommario):

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 obtain

Abstract (sommario):

The hydrodeoxygenation (HDO) of biomass pyrolysis oil (BPO) was evaluated in the presence of two commercial alumina-supported transition metal catalysts, NiMo/alumina-1 (NM1) and NiMo/alumina-2 (NM2). The study explored two characteristic aspects: how HDO reaction conditions affected the oxygen content, density, and boiling point distribution of BPO with varying temperature and HDO reaction time, and the roles of catalysts. Characterizations of HDO-treated oils included elemental analysis, GC-MS, SIMDIS, 13C NMR, and 1H NMR, and characterizations of catalysts included NH3-TPD, XRF, and TPO-MS

Abstract (sommario):

Nuclear Magnetic Resonance (NMR) is a RF technique that is able to detect any compound by sensing the excited resonance signals from atomic nuclei having non-zero spin. NQR is similar to NMR but the only difference is NMR needs a DC magnetic field and due to this its application in the field is limited. A FPGA based NQR spectrometer is designed using a single FPGA chip to perform the digital tasks required for NQR spectrometer. Design of Probe for NMR/NQR spectrometer is researched. Parallel tuned and series tuned Probes are discussed and simulated.14N NQR from

Abstract (sommario):

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

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.

The low-field (27.4 MHz) 19F NMR spectra contained well-resolved signals for the three fluorine containing compounds and univariate calibration was adequate.

Abstract (sommario):

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 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,

Spectroscopic techniques such as Nuclear Magnetic Resonance (NMR), near infrared (NIR), and mid-infrared (mIR) have arisen as strong candidates for the task.

Severe symptoms of the infection may lead to death that prompt appropriate clinical diagnosis and adequate treatment going to be necessary. Covid-19 shows a severe inflammatory response which causes an imbalance in the immune response. Therefore, circulating biomarkers that can represent inflammation and immune status are potential predictors for the prognosis of COVID-19 patients.

Furthermore, by spin diffusion experiments using the Goldman-Shen pulse sequence, the size of the PVC phase domains was semiquantitatively evaluated to be 4.2 nm in the case of the cylindrical domains and to be 5.1 nm in the case of the spherical domains.

A π-extended “earring” subporphyrin 3 was synthesized from β,β′-diiodosubporphyrin and diboryltripyrrane via a Suzuki–Miyaura coupling and following oxidation. Its Pd complex 3Pd was also synthesized and both of the compounds were fully characterized by 1H NMR, MS and X-ray single crystal diffraction. The 1H NMR spectra and single crystal structures revealed that aromatic ring current did not extend to the “ear” in both of the two compounds. Their UV–vis/NIR spectra were recorded and the absorption of both compounds is extended to the NIR region and that the absorption of 3Pd is further red-sh

Abstract Abstract 1908 Poster Board I-931 Previous studies of patients (pts) with polycythemia vera (PV) treated with pegylated interferon (peg-IFNá-2a) have shown an 83% complete hematologic response associated with an 89% molecular response over a median of 11 months (Kiladjian et al. Blood. 2008. 112(8):3065-3072) implying a causative relationship between molecular and hematologic responses. Our data show pts treated with rIFNá-2b or non-rIFNá-2b agents achieve hematologic response despite the absence of a molecular response suggesting that a molecular change is not a prerequisite to hem

Abstract (sommario):

Abstract In vulcanization, chemical crosslinks are formed across elastomeric polymer chains improving both the strength and elastic properties of the rubber. An understanding of the formation, structure, and stability of vulcanizates is therefore very important. Solid-state NMR and NMR imaging have been effective methods to study many different aspects of vulcanization. In solid-state NMR, several peaks appear in the C-13 spectrum of vulcanized rubber. Through model studies, NMR analysis, and chemical shift additivity calculations, these peaks were assigned to their respective vulcanizate stru

The aim of this study is to investigate the diagnostic efficacy of neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-monocyte ratio (NMR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) in patients with Crohn’s disease (CD) and non-CD controls. These ratios were all derived from complete blood counts. Two hundred and six participants including CD inpatients and non-CD controls were retrospectively enrolled. We found statistically higher NLR and PLR and lower LMR in CD patients than in non-CD controls (all P<0.01). However, NMR was not different between the two

Abstract (sommario):

The development of anilinium 2-acrylamide-2-methyl-1-propanesulfonate (Ani-AMPS) monomer, confirmed by 1H NMR, 13C NMR, and FTIR, is systematically studied. Ani-AMPS contains two polymerizable functional groups, so it was submitted to selective polymerization either by free-radical or oxidative polymerization. Therefore, poly(anilinium 2-acrylamide-2-methyl-1-propanesulfonic) [Poly(Ani-AMPS)] and polyaniline doped with 2-acrylamide-2-methyl-1-propanesulfonic acid [PAni-AMPS] can be obtained. First, the acrylamide polymer, poly(Ani-AMPS), favored the π-stacking of the anilinium group produced b

Abstract (sommario):

Since Hg2+ has catalyzed the hydrolysis of quinalphos and ESI-MS detects species in the gas phase [1], 1H and 31P NMR studies were carried out in this work in order to verify whether the metal ions bind to the quinalphos (Q) and its products in solution. The NMR results show clearly that binding between Hg2+ and quinalphos occurs primarily through the S atom. However, small 1H shifts suggest weaker interaction through N. This support strongly that Hg2+ may form a six membered ring with quinalphos and that this complex enhancing the hydrolysis rates.
