Rare earths have been extensively developed in recent years, however, new hosts allow high excitation and emission efficiency, in this sense, gadolinium vanadate has been extensively studied and in previous works it has been widely used in down conversion systems. Because of the strong absorption of the VO4 groups and efficient energy transfer from GdVO4 to lanthanide ions, in this work its up-conversion properties were studied when is co-doped with Yb3+, X3+ where X = Tm, Er and Ho. The powders synthesized presented a high crystallinity and a rounded morphology and exhibit a high luminescence when are excited with IR radiation.

Differentiation of human osteosarcoma 3AB-OS stem-like cells in derivatives of the three primary germ layers as a useful <i>in vitro</i>model to develop several purposes

Stem Cell Discovery 2013年第3期3卷 188-201页

A number of solid tumors contain a distinct subpopulation of cells, termed cancer stem cells (CSCs) which represent the source for tissue renewal and hold malignant potential and which would be responsible for therapy resistance. Today, the winning goal in cancer research would be to find drugs to kill both cancer cells and cancer stem cells, while sparing normal cells. Osteosarcoma is an aggressive pediatric tumor of growing bones that, despite surgery and chemotherapy, is prone to relapse. We have recently selected from human osteosarcoma MG63 cells a cancer stem-like cell line (3AB-OS), which has unlimited proliferative potential, high levels of stemness-related markers, and in vivo tumorforming capacity in xenograft assays. Here, we have shown that 3AB-OS cells can differentiate in vitro into endoderm-, mesoderm-and ectoderm-derived lineages. Cell differentiation is morphological, molecular and functional. We propose that this model system of 3AB-OS differentiation in vitro might have a number of useful purposes, among which the study of molecular mechanisms of osteosarcoma origin, and the analysis of factors involved in specification of the various cell lineages. We still do not know either what are the shared and distinguishing characters between CSCs and normal stem cells, or what is the reason why the cancer stem cells, like the normal stem cells, have the ability to differentiate toward the derivatives of the primary germ layers. It is possible that each of the differentiation capability may be exploited by CSCs to supply their needs of growing and surviving in hostile microenvironment.

Low-Cost CSI Using Forensic GPR, 3D Reconstruction, and GIS

引用

Journal of Geographic Information System 2019年第5期11卷 493-499页

作者： Pier Matteo Barone rosa Maria Di Maggio Archaeology and Classics Program American University of Rome Rome Italy -Forensic Geoscience Italy Rome Italy AcISF-Accademia Italiana di Scienze Forensi Reggio Emilia Italy.

At a time in which several law enforcement agencies all around the world are facing severe expenditure reviews, the increasing use of low-cost solutions during crime scene investigations (CSI) can be a sustainable solution without being detracting from a scientific and rigorous forensic approach. Recently, some private companies are trying to satisfy the growing needs of the police to have cheaper and faster techniques to survey crime scenes and to obtain results with scientifically high-level outputs, more or less comparable with similar outputs from more expensive instruments. This paper reported results from a crime scene in which a low-cost GPR instrument, a free 3D photogrammetry software, and an open-source geographical information system (GIS) were deployed. The collection, processing, and analyses of these data will provide a very promising starting point for future low-cost and professional applications.

Outcomes of severe sepsis and septic shock patients after stratifi cation by initial lactate value

World Journal of Emergency Medicine 2018年第2期9卷 113-117页

Doshi department of Emergency Medicine McGovern Medical School at UTHealth Houston TX USA McGovern Medical School at UTHealth Houston TX USA Division of Critical Care Department of Internal Medicine McGovern Medical School at UTHealth Houston TX USA department of Emergency Medicine University of California San Francisco CA USA Memorial Hermann Hospital - Texas Medical Center Houston TX USA department of Internal Medicine McGovern Medical School at UTHealth Houston TX USA

BACKGROUND: In the setting of severe sepsis and septic shock, mortality increases when lactate levels are ≥ 4 mmol/L. However, the consequences of lower lactate levels in this population are not well understood. The study aimed to determine the in-hospital mortality associated with severe sepsis and septic shock when initial lactate levels are ded into three groups based on initial lactate values. Group 1 had lactate levels demonstrated higher odds of death with higher lactate tier group, however the findings did not reach statistical significance.CONCLUSION: This study found that only assignment to group 3, initial lactic acid level of ≥ 4 mmol/L, was independently associated with increased mortality after correcting for underlying severity of illness and organ dysfunction. However, rising lactate levels in the other two groups were associated with increased severity of illness and were inversely proportional to prognosis.

Photoluminescent Properties of CoMoO_(4)Nanorods Quickly Synthesized and Annealed in a Domestic Microwave Oven

引用

Advances in Chemical Engineering and Science 2012年第4期2卷 465-473页

A simple way to prepare α- and β-CoMoO4 nanorods is reported in this paper. CoMoO4xH2O nanorod precursors were obtained using the microwave-assisted hydrothermal (MAH) method. By annealing the as-prepared CoMoO44xH2O precursor at 600℃ for 10 min in a domestic microwave oven, α- and β-CoMoO4 nanorods were prepared. These powders were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform Raman microscopy and ultraviolet visible absorption spectroscopy (UV-vis spectra) as well as photoluminescence (PL) measurements. Based on the results, these materials revealed nanorod morphology. PL spectra obtained at room temperature for α- and β-CoMoO4 particles exhibited maximum components around the blue light emission. The results show that the domestic microwave oven has been successfully employed to obtain α- and β-CoMoO4 nanoparticles.

A longitudinal study in atypical Cri-du chat profile: A single case report

引用

Case Reports in Clinical Medicine 2013年第2期2卷 100-107页

作者： Maria rosa Pizzamiglio Cristino Volpe Laura Piccardi Centro Ricerche di Neuropsicologia IRCCS Fondazione Santa Lucia Rome Italy Servizio di Riabilitazione Infantile IRCCS Fondazione Santa Lucia Rome Italy

Background: Cri-du-Chat Syndrome (CdCS) is a rare genetic disorder characterized by a severe mental delay, minimal verbal abilities and severe learning difficulties. Methods: Here, we report two neuropsychological assessments of an Italian girl (FS) with CdCS who was affected by a moderate mental delay. The first assessment was made at 2.3 years and second at 6.5 years. Results: Her cognitive profile was characterized by a discrepancy between social-communicative and visual-motor skills. Specifically, her linguistic skills were better than her ability to copy a drawing or play with a set of building blocks. FS showed good lexical competence in both comprehension and production. Differently, her grammatical skills (i.e. comprehension and production) were somewhat defective. Conclusion: The FS’s case, due to her moderate mental delay and her preserved linguistic skills, allowed investigating some aspects of this syndrome never explored before.
