The effect of Serum Copper and Zinc levels on the Immunity of Children

open access: yesMediterranean Journal of Hematology and Infectious Diseases, 2014
Background: the proper zinc and copper levels seem very important to our immune system. Because of association of copper and zinc in many enzymes structures, and also the important role of them in the immune system most of the evaluations have considered

Structural Insights From HIV-Antibody Co-Evolution And Related Immunization Studies [PDF]

open access: yes, 2018
Human immunodeficiency virus type 1 (HIV-1) is a rapidly evolving pathogen and causes the acquired immunodeficiency syndrome (AIDS) in humans. There are ~30-35 million people infected with HIV around the world, and ~25 million have died since the first ...

Biophysical analysis of angiotensin II and amyloid‐β cross‐interaction in aggregation and membrane disruption

open access: yesFEBS Letters, EarlyView.
Angiotensin II (AngII), a neuropeptide, interacts with amyloid‐β (Aβ), a key player in Alzheimer's disease. This study reveals that AngII reduces Aβ aggregation and membrane disruption in vitro. Biophysical assays and molecular modeling suggest AngII binds disordered Aβ forms, potentially modulating early amyloidogenic events and contributing to ...

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Synthesis And Characterization Of (pyNO−)2GaCl: A Redox-Active Gallium Complex [PDF]

open access: yes, 2018
We report the synthesis of a gallium complex incorporating redox-active pyridyl nitroxide ligands. The (pyNO−)2GaCl complex was prepared in 85% yield via a salt metathesis route and was characterized by 1H and 13C NMR spectroscopies, X-ray diffraction ...

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

open access: yesFEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Influence Of DNA On The Rate Of Porphyrin Metallation [PDF]

open access: yes, 1987
Poly(dG–dC)₂ and poly(dA–dT)₂ have marked influences on the rate of insertion of copper(II) into cationic porphyrins reflecting the interaction mode of the porphyrin with the nucleic ...

Atmospheric Chemistry and Physics

open access: yes, 2001
European scale harmonized monitoring of atmospheric composition was initiated in the early 1970s, and the activity has generated a comprehensive dataset (available at http://www.emep.int) which allows the evaluation of regional and spatial trends of air ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Nonadiabatic Electronic Interactions In The Ion-Pair States Of NelCl [PDF]

open access: yes, 1991
Nonadiabatic interactions in the NeIC1 van der Waals complex have been explored in the lowest energy triad of IC1 ion-pair states (approximately 39 000 cm-1).
