“…Such hybrid fibers aligned and segregated from the PS-b-PCEMA-b-PAA nanotubes in a magnetic field. Superparamagetic particles were prepared previously in polymer films, [9,13] , polymer gel particles, [14] in microemulsion droplets, [15] and in lipid vesicles. [16] Preparation of magnetic nanofibers in the channels of ion-track-etched membranes [11] or anodized alumina [17] and in tubes of conductive polymers has also been reported.…”

“…Generally, F0 mutants with more parameters affected, or with more extreme differences in the parameters affected, displayed larger Euclidian distances; those with few or with mildly-affected parameters displayed smaller Euclidean distances. Code for this analysis is available on GitHub ( Kroll, 2022 ). Prism 9 (GraphPad) was used for statistics and plotting for Figure 1—figure supplement 4 .…”

linc-mipep and linc-wrb encode micropeptides that regulate chromatin accessibility in vertebrate-specific neural cells

Thousands of long intergenic non-coding RNAs (lincRNAs) are transcribed throughout the vertebrate genome. A subset of lincRNAs enriched in developing brains have recently been found to contain cryptic open-reading frames and are speculated to encode micropeptides. However, systematic identification and functional assessment of these transcripts have been hindered by technical challenges caused by their small size. Here, we show that two putative lincRNAs (linc-mipep, also called lnc-rps25, and linc-wrb) encode micropeptides with homology to the vertebrate-specific chromatin architectural protein, Hmgn1, and demonstrate that they are required for development of vertebrate-specific brain cell types. Specifically, we show that NMDA receptor-mediated pathways are dysregulated in zebrafish lacking these micropeptides and that their loss preferentially alters the gene regulatory networks that establish cerebellar cells and oligodendrocytes – evolutionarily newer cell types that develop postnatally in humans. These findings reveal a key missing link in the evolution of vertebrate brain cell development and illustrate a genetic basis for how some neural cell types are more susceptible to chromatin disruptions, with implications for neurodevelopmental disorders and disease.

“…G blocks with zigzag confi guration are usually considered responsible for encapsulation and complexation of anions such as Au 3+ , Ag + , Ce 3+ , Cd 2+ , Cr 3+ , Fe 2+ , Ca 2+ , Zn 2+ , Co 2+ , Ni 2+ , Hg 2+ , etc. [ 1,[7][8][9][10][11][12] Alginate is rich in carboxyl and hydroxyl groups, which are considered to be active centers for reduction. Nevertheless, to the best of our knowledge, sodium alginate has been used for in situ preparation of Au NPs starting from gold precursors but always in the presence of another reducing agent, and the synthesis was carried out via either chemical-, photo-, or plasma sputtering reductionprocess.…”

Freestanding natural polymeric films with homogeneous dispersion of gold nanoparticles (Au NPs) are obtained via in situ reduction of gold(III) chloride trihydrate by sodium alginate (SA) biopolymer matrix, during water evaporation without the use of additional reducing agents. The size and size distribution of the prepared Au NPs can be tuned by changing the concentration of the precursor and/or the procedure of the films’ preparation. The nanocomposite films after preparation are stable in ambient conditions and can be used without the need of further processing, or can be redissolved in water. In the case of water dissolution, the aqueous solutions are irradiated with UV laser pulses turning the previously formed Au NPs into smaller ones with narrow size distributions through photofragmentation. This technique is proposed as a green way of synthesizing Au NPs of tunable size in aqueous solution of alginate, or incorporated in alginate freestanding polymeric films, that due to their biocompatibility can be used as passive labels or active sensors in biomedical applications.
