Publication date: 15 December 2018Source: Journal of Non-Crystalline Solids, Volume 502Author(s): Y. Shen, J.H. PerepezkoAbstractDuring isothermal annealing at temperatures lower than the crystallization onset temperature, Tx, measured during continuous heating, the Al88Y7Fe5 metallic glass undergoes a period of delay time (τ) before the primary crystallization reaction. The delay time is an important parameter, which is closely related with the transport behavior and can be used to calculate the attachment frequency coefficient and steady state nucleation rate. Previously, τ was usually determined from the nanocry...

Publication date: Available online 22 October 2018Source: Inorganica Chimica ActaAuthor(s): Balkaran Singh Sran, Sanyog Sharma, Geeta HundalAbstractSupramolecular isomerism and structural transformations have been studied for four coordination compounds of Cu(II) with L as N, N-diisopropylisonicotinamide. Three different compounds [Cu(L)2(NO3)2(H2O)1.5] (1), [Cu(L)2(NO3)2]n(2) and [Cu(L)(NO3)2]n (3) were synthesized from the same reactants having metal-to-ligand ratio of 1:1 or 3:1, under different reaction conditions. 1 is a simple coordination compound while 2 and 3 are 1D coordination polymers (CPs). 1 shows a thermally...

In this study, paraffin/red mud phase change energy storage composites were fabricated at 4 mix proportions with paraffin to red mud ratios of 0.4:0.6, 0.45:0.55, 0.5:0.5, and 0.55:0.45 by a mixed mill-heating method. Scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) results reveal that paraffin flows well into red mud pores and has good compatibility. The differential scanning calorimetry (DSC) results reveal that the melting temperatures of the paraffin/red mud phase change energy storage composite vary from 75℃ to 85℃, and the latent heat value is approximately 25~40J/g. High thermal stabilit...

Authors: Chen S, Ye M Abstract Mantle cell lymphoma (MCL) is a subtype of B-cell non-Hodgkin lymphoma. Heterogeneous and extensive lymphadenopathy is the most common clinical manifestation. Although skeletal involvement is not uncommon in other types of non-Hodgkin lymphoma, primary bone MCL is rare. The present study reported a case of primary tibia MCL in a 50-year-old male presenting with left tibia pain and a rapidly growing lump. Computed tomography and magnetic resonance imaging scans revealed a progressive lesion in the cortical bone and surrounding soft tissue mass. A positron emission computed tomography s...

Iodine-125 interstitial brachytherapy reduces tumor growth via Warburg effect inhibition in non-small cell lung cancer A549 ×enografts. Oncol Lett. 2018 Nov;16(5):5969-5977 Authors: Zhang J, Zhu Y, Dong M, Yang J, Weng W, Teng L Abstract Iodine-125 interstitial brachytherapy (125I-IBT) is an alternative and effective treatment option for unresectable non-small cell lung cancer (NSCLC), and the Warburg effect is a determinant of tumor growth. The present study aimed to explore the influence of 125I-IBT on tumor growth and the Warburg effect, and the potential mechanisms underlying NSCLC progressio...

ConclusionFindings support the involvement of frontal, striatal, and limbic regions in methamphetamine dependence. Furthermore, they indicate that glucose metabolism and cerebral perfusion in these regions are disrupted in methamphetamine dependent individuals with psychotic symptoms.

In this study we used a novel graph wavelet algorithm to determine the extent to which microstructural brain changes evolve in concert with the development of AD neuropathology as observed using CSF biomarkers. A total of 118 participants with at least two diffusion tensor imaging (DTI) scans and one lumbar puncture for CSF were selected from two observational and longitudinally followed cohorts. CSF was assayed for pathology specific to AD (Aβ42 and phosphorylated-tau), neurodegeneration (total-tau), axonal degeneration (neurofilament light chain protein; NFL), and synaptic degeneration (neurogranin). Tractography wa...

A new type of medical scanning technology that would provide precise, radiation therapy for cancer patients will be coming to Barnes-Jewish Hospital and Washington University School of Medicine in St. Louis in 2020. The technology known as pencil-beam scanning will deliver extremely precise treatments of proton therapy, a type of radiation therapy used to treat cancers of the head, chest, spine and other sensitive areas, as well as pediatric cancers. Siteman Cancer Center is also the home to another…
