Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

open access: yesLubricants, 2020
In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive ...

Conserved secondary structures in Aspergillus. [PDF]

open access: yesPLoS ONE, 2008
Recent evidence suggests that the number and variety of functional RNAs (ncRNAs as well as cis-acting RNA elements within mRNAs) is much higher than previously thought; thus, the ability to computationally predict and analyze RNAs has taken on new ...

Pre-mRNA secondary structures influence exon recognition. [PDF]

open access: yesPLoS Genetics, 2007
The secondary structure of a pre-mRNA influences a number of processing steps including alternative splicing. Since most splicing regulatory proteins bind to single-stranded RNA, the sequestration of RNA into double strands could prevent their binding ...

Inhibition and Mechanism of Protein Nonenzymatic Glycation by Lactobacillus fermentum

open access: yesFoods
Lactobacillus fermentum (L. fermentum) was first evaluated as a potential advanced glycation end-product (AGE) formation inhibitor by establishing a bovine serum albumin (BSA) + glucose (glu) glycation model in the present study.

Conformational features of topologically classified RNA secondary structures. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Current RNA secondary structure prediction approaches predict prevalent pseudoknots such as the H-pseudoknot and kissing hairpin. The number of possible structures increases drastically when more complex pseudoknots are considered, thus ...

Effects of ultrasound treatment on the morphological characteristics, structures and emulsifying properties of genipin cross-linked myofibrillar protein

open access: yesUltrasonics Sonochemistry, 2023
Genipin is a natural crosslinker that improves the functional properties of proteins by modifying its structures. This study aimed to investigate the effects of sonication on the emulsifying properties of different genipin concentration-induced ...

SECONDARY STRUCTURES OF DNA [PDF]

open access: yesProceedings of the National Academy of Sciences, 1969
In view of the differences of the X-ray diffraction patterns for DNA fibers at 66 and 92 per cent relative humidities, it is proposed that the secondary structure of DNA consists of two partially intercalated double helices at 92 per cent. Possible biological implications are discussed.
