Aims This study investigated effects of narrow-range ultraviolet irradiation (UVR) by a new UV-LED device on vitamin D supply and changes of bone in senescence-accelerated mouse P6 (SAMP6) with vitamin D deficiency. Main methods We used female SAMP6 mice as a senile osteoporotic model. We set a total of 3 groups (n = 4 per group); D-UVR+ group (vitamin D deficient-dietary and UVR), D- (vitamin D deficient-dietary), and D+ groups (vitamin D contained-dietary). Mice in the D-UVR + group were UV-irradiated (305nm) with 1 kJ/m2 twice a week for 12 weeks from 20 to 32 weeks of age. Serum 25(OH)D, 1,25(OH)2D, and micro-computed tomography (CT) were assessed over time. Mechanical test, and histological assay were performed for femurs removed at 32 weeks of age. click here Key findings UVR increased both serum 25(OH)D and 1,25(OH)2D levels at 4 and 8 weeks-UVR in the D-UVR+ group compared with that in the D- group (P less then 0.05, respectively). Relative levels of trabecular bone mineral density in micro-CT were higher in the D-UVR+ group than in the D- group at 8 weeks-UVR (P = 0.048). The ultimate load was significantly higher in the D-UVR+ group than in the D- group (P = 0.036). In histological assay, fewer osteoclasts and less immature bone (/mature bone) could be observed in the D-UVR+ group than in the D- group, significantly. Significance UVR may have possibility to improve bone metabolism associated with vitamin D deficiency in SAMP6 mice. © 2020 The Author(s).Imidazolium bearing ionic liquids (ILs), 3-hexadecyl-1-methyl-1H-imidazol-3-ium bromide [C16M1Im] [Br] and 3-hexadecyl-1,2-dimethyl-1H-imidazol-3-ium bromide [C16M2Im] [Br] have been synthesized. These compounds were evaluated for corrosion resistance of mild steel in 1M HCl solution by gravimetric and electrochemical studies. The results were noticed that the inhibition efficiency, has enhanced due to a rise in the concentration of inhibitor. Further, it is observed that [C16M2Im] [Br] inhibition efficiency better than [C16M1Im] [Br] due to the increased alkyl substituents. Polarization study reveals that the used inhibitors behave as a mixed type, but predominantly exhibited the anodic inhibitive effect. The inhibitors adsorbed on the metal surface obeys Langmuir adsorption isotherm. Surface topography examined using an Atomic Force Microscope (AFM) and a Scanning Electron Microscope (SEM) with EDAX analyses. The formation of the Fe-inhibitor complex on mild steel surface has been confirmed by UV-Visible spectroscopy. © 2020 Published by Elsevier Ltd.Quasibinary section solid solutions of a four-component system of the (1-x)(Na0.5K0.5)NbO3-xPb(Ti0.5Zr0.5)O3 composition, based on compositions with fundamentally different physical responses (Na, K)NbO3(KNN), Pb(Ti, Zr)O3 (PZT), have been produced by two-step solid-phase synthesis followed by sintering using conventional ceramic technology. The features of their structural formation have been revealed, a phase diagram of equilibria has been constructed, correlation relationships composition ‒ structure ‒ microstructure ‒ macroproperties have been established. Based on the measured X-ray fluorescence intensities, the concentrations of chemical elements, included in the surface composition of the samples of piezoceramic materials, have been determined. Statistical characteristics and variations in the chemical composition of the structure-forming chemical elements of the ferroactive composite materials were researched. Micro-XRF combined with methods of mathematical statistics provides to characterize a degree of chemical homogeneity and statistically compare the average concentrations of the chemical elements. Changes in atomic concentrations were revealed as result of varying technological conditions of synthesis. We have carried out the X-ray quantitative analysis for the thickness of surface layer corresponding to the chemical elements at the depth yield of X-ray fluorescence. Three groups of solid solutions ‒ the foundations of intelligent materials have been identified with high K p , ε 33 T/ε 0 low V 1 E (near PZT) - promising for low-frequency applications; with low ε 33 T/ε0, high V 1 E (near KNN) ‒ for high-frequency use; with intermediate values of the piezoelectric parameters (near SS1→SS2 ‒ transition), intended for operation in combined equipment complexes. © 2020 The Author(s).Background Recent studies have suggested that the incidence of in-hospital pulseless electrical activity (PEA) arrests is increasing. Bradycardia in patients with in-hospital PEA is common but it is unknown if it is associated with respiratory arrest or patient outcomes. Objective To determine risk factors and outcomes associated with bradycardic-PEA arrests, and relationship between bradycardia and respiratory arrest. Methods This was a retrospective cohort study of all inpatient cardiac arrests at an academic medical center over a four-year period. Patient demographics, comorbidities, vital signs, arrest event data, and outcomes were abstracted from the medical record. PEA arrest was defined as a non-shockable rhythm with loss of pulse requiring cardiopulmonary resuscitation and having organized electrocardiographic activity. Bradycardia was classified as a HR less then 60 bpm at the time of pulse loss. The primary outcomes were survival of arrest and survival to hospital discharge. Results Between July 2, and sodium bicarbonate. Conclusion In a retrospective study of hospitalized patients in the intensive care unit and non-intensive care, bradycardia at the time of PEA cardiac arrest was associated with improved survival to hospital discharge but not survival of arrest. Respiratory arrest was an independent predictor of survival, but there was no association between respiratory arrest and bradycardic PEA arrest. © 2020 The Author(s).Background Non-small cell lung carcinoma (NSCLC) incidence and progression is increasing because of genetic and epigenetic changes. The mutations in the Kirsten rat sarcoma (KRAS) are the most frequently oncogene aberrations in lung carcinoma patients. A candidate tumor suppressor gene (TSG) Ras Association Domain Family 1 Isoform A (RASSF1A), is silenced by promoter hypermethylation in several human malignancies including non-small cell lung carcinoma (NSCLC). We hypothesized that RASSF1A methylation and KRAS mutations may play an important role in NSCLC. Methods Non-small cell lung carcinoma patients (n = 100) and equal number of healthy controls were assessed for activating KRAS (exon 2) mutations using allele-specific oligonucleotide polymerase chain reaction (ASO-PCR) and promoter hypermethylation of RASSF1A using methylation specific PCR. Results The frequency of mutations in Kirsten rat sarcoma (KRAS) were found in 31% of NSCLC patients in the Kashmiri population and occur most commonly, but not exclusively, in adenocarcinoma histology and life-long smokers.
