Inhibition by small-molecule ligands of formation of amyloid fibrils of an immunoglobulin light chain variable domain. [PDF]

open access: yes, 2015
Overproduction of immunoglobulin light chains leads to systemic amyloidosis, a lethal disease characterized by the formation of amyloid fibrils in patients' tissues. Excess light chains are in equilibrium between dimers and less stable monomers which can

High-Level Expression of Various Apolipoprotein (a) Isoforms by "Transferrinfection". The Role of Kringle IV Sequences in the Extracellular Association with Low-Density Lipoprotein [PDF]

open access: yes, 1994
Characterization of the assembly of lipoprotein(a) [Lp(a)] is of fundamental importance to understanding the biosynthesis and metabolism of this atherogenic lipoprotein. Since no established cell lines exist that express Lp(a) or apolipoprotein(a) [apo(a)

The Beams Ultracentrifuge [PDF]

open access: yesNature, 1936
AN ultracentrifuge designed by Beams has been in operation in this laboratory for the past year. From information published1,2,3,4, we assumed the forces to be of the order of 5 × 105 times gravity when driven by air at about 80 lb. pressure. On subsequent measurement we find that the maximum force developed is 4 × 106 times gravity.

Comparison of an Optimized Ultracentrifugation Method versus Size-Exclusion Chromatography for Isolation of Exosomes from Human Serum.

open access: yesJournal of Proteome Research, 2018
Exosomes are nanosized vesicles that are abundant in biological fluids. In recent years, exosomes have attracted increasing attention as their cargo may provide promising biomarkers for the early diagnosis of and therapy for many diseases, such as cancer.

Optimization of Methods for Determination of the Encapsulation Efficiency of Doxorubicin in the Nanoparticles Based on Poly(lactic-co-glycolic acid) (PLGA)

open access: yesРазработка и регистрация лекарственных средств, 2020
Introduction. Drug encapsulation efficiency (EE) is the important parameter of the nanoparticle-based drug formulations. Generally, the methods for evaluation of the EE are based on separation of the free and NP-bound fractions of the drug; however ...

Bioavailability of Cu and Zn in raw and anaerobically digested pig slurry [PDF]

open access: yes, 2009
The impact of anaerobic digestion on the bioavailability of copper and zinc from pig slurry was assessed. Both chemical and biological approaches were used independently on raw slurry (RS) and anaerobically digested pig slurry (DS).

A coiled‐coil domain triggers oligomerization of MmpL10, the mycobacterial transporter of trehalose polyphleate precursor

open access: yesFEBS Letters, EarlyView.
Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

The Solution Structures of Two Human IgG1 Antibodies Show Conformational Stability and Accommodate Their C1q and FcγR Ligands. [PDF]

open access: yes, 2015
The human IgG1 antibody subclass shows distinct properties compared with the IgG2, IgG3, and IgG4 subclasses and is the most exploited subclass in therapeutic antibodies. It is the most abundant subclass, has a half-life as long as that of IgG2 and IgG4,
