Effect of levamisole on alkaline phosphatase activity and immunoglobulin secretion of lipopolysaccharide-stimulated murine splenic lymphocytes

Biomedical and Biotechnology Research Journal, 2017
Background: Alkaline phosphatases (APase) are a group of enzymes whose activity increases above normal levels in conditions of diseases such as cancer. In the present study, the role of APase using mitogen-stimulated murine lymphocytes was investigated ...

Investigation of liquid distribution in gas–solid fluidized beds for fluid cokers

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Thermal cracking processes convert larger molecules into smaller, more valuable products, without a catalyst, allowing for transforming residual oils or waste plastics into useful compounds. Fluid coking, a thermal cracking process utilizing a fluidized bed of hot particles, processes approximately 1 million barrels of residual oil daily. This

A Direct Measurement of the Absolute Energies of Protonated Gly‐Pro‐Gly‐Gly Conformations Using Ion Mobility Spectrometry and Guided Ion Beam Tandem Mass Spectrometry

ChemPhysChem, EarlyView.
Relative energies of the cis and trans conformers of the protonated tetrapeptide, Gly‐Pro‐Gly‐Gly, selected by ion mobility spectrometry are measured using threshold collision‐induced dissociation. The trans conformation was found to be more stable than the cis conformation by 4.5 ± 2.5 kJ mol−1 at 0 K, a value in agreement with several levels of ...

Conformation Dependent Room Temperature Phosphorescence in Organic Materials

ChemPhotoChem, EarlyView.
Room temperature phosphorescence from organic materials in the solid state can be tuned owing to changes in the molecular arrangement occurring in crystalline and amorphous phases. This review presents recent results that discuss conformation dependent triplet emission, revealing its role in the design of organic functional materials with diverse ...

Effect of the Electrolyte on the Oxygen Reduction Reaction with a MOF Embedded Co‐Porphyrin

ChemSusChem, EarlyView.
The reduction of dioxygen to hydrogen peroxide in the PCN‐224(Co) MOF is limited by the intrinsic catalytic activity of the cobalt sites rather than the diffusion of charge or the mass‐transport of reagents. The more strongly coordinating cations affect the catalytic activity slightly negatively, while the concentrations of buffer and oxygen ...

Boosting Light‐Driven CO2 Conversion Into CO by a Polypyridine Iron(II) Catalyst Using an Organic Sensitizer

ChemSusChem, EarlyView.
The combination of a thermally‐activated delayed fluorescence (TADF) dye with a heptacoordinated iron complex as a catalyst allows to achieve a noble‐metal‐free photochemical system capable of boosting light‐driven catalytic conversion of CO2 into CO with unprecedented (quantum) efficiencies and almost unitary selectivity. Abstract Direct photochemical

Solid State Structures of Three Zinc(II) Coordination Polymers with 3‐(1H‐Imidazol‐1‐yl)propanoate Linkers Prepared in Water

European Journal of Inorganic Chemistry, Accepted Article.
Coordination polymers of zinc(II) with three readily accessible 3‐(1H‐imidazol‐1‐yl)propanoate ligands are prepared by combining aqueous solutions of the ligands and zinc(II) salts, resulting in a precipitation of the respective coordination polymers.

Reordering the machinery of participation with young people

Sociology of Health &Illness, Volume 44, Issue S1, Page 90-105, December 2022., 2022
Abstract In this article, we reflect on our ongoing work that attempts to redistribute the agenda‐setting powers of researchers, research funders and the complex of private and public partnerships in the biomedical sciences. Despite calls for diversification, the current landscape is dominated by a traditional medical habitus that prioritises discovery

Study of a Positron Emission Mammograph [PDF]

, 2007
Today breast cancer is among the most common causes of death for women. One in eight women will develop a tumour in her breast at least once in her lifetime. An early detection of the cancer is crucial to the patient's survival and recovery.
