Time series Fourier transform infrared spectroscopy for characterization of water vapor sorption in hydrophilic and hydrophobic polymeric films

This work investigates the nature of the molecular interactions between water vapor and polymers using time series Fourier transform infrared (FTIR) spectroscopy. A detailed analysis of the frequency shifts and relative peak intensities led to the conclusion that polyvinyl alcohol (PVOH) sorbed a large quantity of water vapor molecules, resulting in swelling and dissolving of polymer crystallites. Difference spectra were calculated to investigate spectral changes occurring upon sorption by dividing the spectra of polymers during the sorption time series by the spectrum of the dry sample and subsequently subtracting the water vapor spectrum. Based on the absorbance area of the OH stretching vibration region (4000-3000 cm(-1)) in difference spectra, the amount of water sorbed was significantly higher in poly-L-lactic acid (PLLA) and polyvinyl chloride (PVC) than in polyethylene (PE) and polytetrafluoroethylene (PTFE), increasing with the hydrophilicity of the surface. The OH stretching band of difference spectra shifted from 3499 cm(-1) for PVC, to 3416 cm(-1) for PE and finally to 3387 cm(-1) for PTFE, indicating a more strengthened hydrogen-bonding network in the PTFE matrix upon water vapor sorption.

Lifetime alcohol intake, drinking patterns over time and risk of stomach cancer: A pooled analysis of data from two prospective cohort studies

Alcohol consumption is causally linked to several cancers but the evidence for stomach cancer is inconclusive. In our study, the association between long-term alcohol intake and risk of stomach cancer and its subtypes was evaluated. We performed a pooled analysis of data collected at baseline from 491 714 participants in the European Prospective Investigation into Cancer and Nutrition and the Melbourne Collaborative Cohort Study. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated for incident stomach cancer in relation to lifetime alcohol intake and group-based life course intake trajectories, adjusted for potential confounders including Helicobacter pylori infection. In all, 1225 incident stomach cancers (78% noncardia) were diagnosed over 7 094 637 person-years; 984 in 382 957 study participants with lifetime alcohol intake data (5 455 507 person-years). Although lifetime alcohol intake was not associated with overall stomach cancer risk, we observed a weak positive association with noncardia cancer (HR = 1.03, 95% CI: 1.00-1.06 per 10 g/d increment), with a HR of 1.50 (95% CI: 1.08-2.09) for >= 60 g/d compared to 0.1 to 4.9 g/d. A weak inverse association with cardia cancer (HR = 0.93, 95% CI: 0.87-1.00) was also observed. HRs of 1.48 (95% CI: 1.10-1.99) for noncardia and 0.51 (95% CI: 0.26-1.03) for cardia cancer were observed for a life course trajectory characterized by heavy decreasing intake compared to light stable intake (P-homogeneity = .02). These associations did not differ appreciably by smoking or H pylori infection status. Limiting alcohol use during lifetime, particularly avoiding heavy use during early adulthood, might help prevent noncardia stomach cancer. Heterogeneous associations observed for cardia and noncardia cancers may indicate etiologic differences.

Synthetic Route of 768-95-6, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 768-95-6 is helpful to your research.

Gelatin/Poly (vinyl alcohol)/Inorganic filler composites for phantom breasts

The effect of the various inorganic filler (Zn, ZnO, CuO, Co(NO3)(2), Fe2O3) on the structural, electronic, atomic, and absorption properties to the performance of composite phantom breast with polyvinyl alcohol (PVA) as a binder has been studied. The bonding characteristic analyzed from the Fourier transforms infrared (FTIR) spectra and the structural properties in the form of the crystallite size, porosity, and dislocation density determined from the X-ray diffraction (XRD) spectra. The atomic, electronic, and absorption ability of composite were analyzed from the irradiation intensity after the X-rays for the energies from 60 keV to 85 keV at 10 mAs passing through the samples. The functional group of C=O, C-H, and C-O show covalent bonding as a cross-linking between atoms from the various filler and the atom from the matrix materials. The crystallite size shows a direct correlation between the linear attenuation coefficient and the mass attenuation coefficient. The linear attenuation coefficient of composite gelatin/PVA/ZnO is 0.255 cm(-1), for composite gelatin/PVA/CuO is 0.233 cm(-1) shows good for breast phantom, and for composite gelatin/PVA/Zn is 0.343 cm(-1 )shows excellent characteristics for breast phantom. This study provided a new composite with excellent characteristics as a guide to produce breast phantom.

Comparative associations of problematic alcohol and cannabis use with suicidal behavior in US military veterans: A population-based study

Alcohol use disorder (AUD) and cannabis use disorder (CUD) are each associated with increased suicidal behavior, but it is unclear how their comorbidity relates to suicide risk. Understanding these associations in U.S. military veterans is especially important, given their heightened risk for suicide, high prevalence of AUD, and increasing access to cannabis. We compared associations of probable AUD, CUD, and AUD/CUD with suicide ideation, plan(s), and attempt(s) in a nationally representative sample of 4,069 veterans surveyed in 2019-2020 as part of the National Health and Resilience in Veterans Study. Among veterans who screened positive for current AUD, 8.7% also screened positive for current CUD. Among veterans who screened positive for current CUD, 33.3% screened positive for current AUD. Current and lifetime positive screens for AUD, CUD, and AUD/ CUD were each strongly and independently associated with past-year suicide ideation and lifetime suicide ideation, plan(s), and attempt(s) [odds ratios (ORs) = 1.6-8.7]. Relative to veterans who screened positive for AUD only, veterans who screened positive for AUD/CUD and CUD only had higher odds of past-year suicide ideation (AUD/CUD: OR = 3.3; CUD only: OR = 2.4), lifetime suicide ideation (AUD/CUD: OR = 1.9; CUD only: OR = 2.6) and lifetime suicide plan(s) (AUD/CUD: OR = 1.7; CUD only: OR = 6.1). Collectively, findings suggest that screening positive for CUD might be an especially strong indicator of suicide ideation and planning in veterans with and without AUD, independent of sociodemographic, military, trauma, and other psychiatric factors. These findings underscore the importance of routine screening for CUD in suicide prevention efforts, especially as cannabis becomes more widely available.

Introducing alcohol as a drug in medicine reviews with pharmacists: Findings from a co-design workshop with patients

Introduction Alcohol poses a range of potential problems to people taking medications, but health professionals are usually not comfortable talking about drinking with patients. The Medicines and Alcohol Consultation aims to increase the capacity of pharmacists to conduct person-centred reviews in which alcohol is regarded as another drug to be discussed alongside medications. This paper explores sensitivities in discussing alcohol and views on the legitimacy of the Medicines and Alcohol Consultation intervention concept at a pharmacy-user intervention co-design workshop. Methods A co-design workshop was held with 14 people recruited from UK community pharmacies who regularly drank alcohol and took medications for long-term conditions. This formed one element of a broader, iterative, intervention co-production process. Workshop discussions were audio-recorded and analysed thematically. Results The basic intervention concept resonated well, though not entirely unproblematically. Participants were interested in receiving information on how medications interact with alcohol and how this might affect their own conditions, with which to make their own informed choices. Linking alcohol use to medicines gave legitimacy to pharmacists to raise alcohol in medicines reviews. Sensitivity in talking about alcohol was linked to vulnerability to negative judgement. Discussion and Conclusions Changing the framing of alcohol in medicines reviews, away from being regarded as a ‘lifestyle issue’ to being considered a drug directly linked to medicines use, safety and effectiveness, was welcomed by participants in this study.

Production and characterization of shape memory polymeric nanocomposite materials

Polymers are macromolecular materials that simple molecules (monomers) come together with chemical bonds and form them. The industrial use area of polymers is increasing due to many advantages of them such as mechanical properties, easy formability, lightweight, and low cost. Properties of smart (capable of reacting to an external effect) polymers; because of external effects such as magnetic field, electric field, temperature, and pH, they can change their shape and various mechanical properties. Areas such as aviation, construction, electronics, and medical can be given as examples to the usage areas of such materials. In this study, poly (vinyl alcohol) (PVA) polymer was used as a matrix in nanocomposite materials. New types of shape memory nanocomposites materials were obtained by using reduced graphene oxide (rGO) and graphene oxide (GO) produced by the Hummers method as fillers. Differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA) devices were used to examine the thermal characterization of materials. X-ray diffraction (XRD) method and Fourier transform infrared spectrometry (FT-IR) were used for structural characterization analysis. In addition, chemical characterization of the materials was investigated using energy diffusion X-ray analysis (EDX) and surface morphology using scanning electron microscopy (SEM). The shape memory performances of the produced nanocomposite materials were determined by the shape recycling tests. It is examined the effect of fillers on the shape memory performance, structural and thermal properties of nanocomposite materials. (C) 2020 Elsevier B.V. All rights reserved.

Joint effect of blood pressure and C-reactive protein and the risk of sudden cardiac death: A prospective cohort study

Background: Both blood pressure and C-reactive protein (CRP) are each independently related to mortality risk. However, the combined effect of systolic blood pressure (SBP) and CRP on sudden cardiac death (SCD) risk has not been studied. Patients and methods: We studied the joint impact of SBP and CRP and the risk of SCD in the Kuopio ischemic Heart Disease prospective cohort study of 1953 men aged 42-61 years with no history of ischemic heart disease. Baseline investigations were conducted between March 1984 and December 1989. SBP and CRP were measured. SBP was divided based on median values to low and high (median cutoffs 132 mmHg) and CRP as low and high (median cut-off 1.30 mg/L). Hazard ratios (HRs) with confidence intervals (CIs) were calculated after multivariate adjustment. Results: Subjects were followed-up for 23.2 years, and 137 SCDs occurred. In this study, elevated OP (>132 mmHg) combined with elevated (CRP >1.30 mg/L) were associated with SCD risk. Adjustment for age, examination year, alcohol consumption, BMI, energy expenditure during exercise, total cholesterol, HDL-cholesterol, type 2 diabetes, smoking, antihypertension medication and aspirin use, the risk of SCD remained statistically significant (HR, 2,73, 95% CI, 1.62-4.60, p < .001). Further adjustment for socio-economic status, years of education and history of cardiovascular disease in a family the results were only slightly changed (HR, 2.65,95% CI, 1.57-4.49, p < .001). Conclusions: In our male cohort study, the joint effect of high SBP together with increased CRP levels is a risk predictor of SCD compared with low SBP and CRP. (C) 2020 Published by Elsevier B.V.

Oxone activation by UVA-irradiated Fe-III-NTA complex: Efficacy, radicals formation and mechanism on crotamiton degradation

This study demonstrated an efficient activation of Oxone by ultraviolet light A-irradiated Fe-III-nitrilotriacetate complex to induce the generation of sulfate and hydroxyl radicals (i.e., SO4 center dot- and HO center dot) under initial neutral pH. The important parameters such as the solution pH, the molar ratio of nitrilotriacetate:Fe-III, the dosages of Oxone and Fe-III-nitrilotriacetate complex were evaluated in terms of the degradation kinetics of an emerging contaminant Crotamiton. The results indicated that fast degradation rates of crotamiton were achieved under initial circumneutral conditions (e.g., pH 5.0-7.0), with apparent rate constants at 0.0936-0.1287 min(-1) (the ultraviolet light fluence-based rate constants at 0.48-0.66 J(-1) cm(2)). In addition, the optimal molar ratio of nitrilotriacetate:Fe-III was determined as 1:1, larger ratios decreased the degradation rate of crotamiton due to the competition effect of nitrilotriacetate on SO4 center dot-. The suitable dosages of Oxone and Fe-III-nitrilotriacetate complex were determined as 0.5 mM and 0.1 mM, respectively. Under the given optimal conditions, more than 99% degradation efficiency of crotamiton was achieved at an ultraviolet light fluence of 3.90 J cm(-2), better than those results obtained by the activation of S2O82- and H2O2. The results of quenching tests (tert-butyl alcohol and 2-propanol as scavengers) suggested that SO4 center dot- and HO center dot contributed similar to 65% and 35% to the degradation of crotamiton, respectively. Furthermore, the identified intermediates includes hydroxy-crotamiton, dihydroxy-crotamiton, aldehyde-crotamiton, aldehyde-dihydroxy-crotamiton, N-ethyl-2,3-dihydroxy-N-(o-tolyl)butanamide, (E)-N-ethyl-N-phenylbut-2-enamide, 2-(ethylamino)benzaldehyde and/or 2-(o-tolylamino)acetaldehyde, and (E)-N-ethylbut-2-enamide. The results indicated that the SO4 center dot- preferentially attacked on the amide and methyl groups of crotamiton. This work provided insight into the efficacy, radicals formation and mechanism on the activation of Oxone by ultraviolet light A-irradiated FeIII-nitrilotriacetate complex, offering an alternative approach for advanced water treatment.

An ultra-sensitive optical aptasensor based on gold nanoparticles/poly vinyl alcohol hydrogel as acceptor/emitter pair for fluorometric detection of digoxin with on/off/on strategy

A novel nanobiosensor was prepared by aptamer and gold nanoparticles conjugate in poly vinyl alcohol hydrogel for sensitive detection of digoxin in human plasma samples. The developed nanobiosensor was characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, and dynamic light scattering instrument. In this sensor the hydrogel acted as a fluorescent probe. The fluorescence intensity of the hydrogel was quenched by aptamer stabilized gold nanoparticles as energy acceptor. Upon addition of digoxin, the aptamer/drug complex was formed and the fluorescence of the hydrogel was restored because of destabilization and aggregation of gold nanoparticles in the presence of salt. The affecting parameters on the nanobiosensor performance were assessed and under the optimized conditions the external and in plasma calibration curves were linear in the 10-1000 ng L-1 digoxin concentration range with detection limits of 2.9 and 3.1 ng L-1, respectively. The relative standard devi-ations for 5 replicate determinations of 50, 250, and 500 ng L-1 of digoxin, were 7.3, 5.1, and 3.8%, respec-tively. This nanofluoroprobe was successfully applied for determination of digoxin in spiked plasma samples without any pretreatment procedure. (C) 2020 Elsevier B.V. All rights reserved.

Immunomodulatory and Antimicrobial potential of ethanolic extract of Himalayan Myrica esculanta in Oncorhynchus mykiss: Molecular modelling with Aeromonas hydrophila functional proteins

The present study was carried out to investigate the antimicrobial and immunomodulatory activity of Myrica esculenta ethanolic leaf extract (MeALE) in rainbow trout. The juvenile fish were immersed in 20 mg/l (T1) and 40 mg/l (T2) MeALE for 2 and 6 h and then challenged with pathogenic bacteria, A. hydrophila (ATCC 7966, USA) after 6 h post immersion in MeALE. The immuno-haematological parameters and relative percentage survival were recorded over 7 days post-exposure. The amino acid interaction of functional proteins of bacteria with myricetin, the active ingredient of M. esculenta was performed by AutoDock Vina software. FTIR detected the characteristic peak values and revealed the presence of various functional groups, viz. alkenes, amines, alcohols, phenols and aromatic compounds. The MIC of MeALE was found to be 2 mg/ml while MBC was recorded to be 25 mg/ml. Molecular docking revealed a strong affinity between myricetin and functional proteins of the pathogen. The fish immersed in 40 mg/l MeALE showed a significant increase in haematological indices and non-specific immunological parameters. The current study reports the successful use of MeALE as an antimicrobial and immunostimulatory agent in rainbow trout and recommends the dosage of 40 mg/l MeALE for preventing Aeromonas infection.
