Superhydrophobic Particles Derived from Nature-Inspired Polyphenol Chemistry for Liquid Marble Formation and Oil Spills Treatment
Nature has given us great inspirations
to fabricate high-performance
materials with extremely exquisite structures. Presently, particles
with a superhydrophobic surface are prepared through nature-inspired
polyphenol chemistry. Briefly, adhering of a typical polyphenol (tannic
acid, widely existed in tea, red wine, chocolate, <i>etc</i>.) is first conducted on titania particles to form a multifunctional
coating, which is further in charge of reducing Ag<sup>+</sup> into
Ag nanoparticles/nanoclusters (NPs/NCs) and responsible for grafting
1H,1H,2H,2H-perfluorodecanethiol, thus forming a lotus-leaf-mimic
surface structure. The chemical/topological structure and superhydrophobic
property of the as-engineered surface are characterized by scanning
electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS),
energy dispersive spectroscopy (EDS), water contact angle measurements,
and so on. On the basis of the hierarchical, superhydrophobic surface,
the particles exhibit a fascinating capability to form liquid marble
and show some possibility in the application of oil removal from water.
After particles are <i>in situ</i> adhered onto melamine
sponges, the acquired particle-functionalized sponge exhibits an absorption
capacity of 73–175 times of its own weight for a series of
oils/organic solvents and shows superior ease of recyclability, suggesting
an impressive capability for treating oil spills

Induced High-Yield Production of Zeaxanthin, Lutein, and β‑Carotene by a Mutant of <i>Chlorella zofingiensis</i>
Natural
resources of zeaxanthin are extremely limited. A <i>Chlorella
zofingiensis</i> mutant (CZ-<i>bkt</i>1),
which could accumulate high amounts of zeaxanthin, was generated and
characterized. CZ-<i>bkt</i>1 was achieved by treating the
algal cells with a chemical mutagen followed by a color-based colony-screening
approach. CZ-<i>bkt</i>1 was found to consist of a dysfunctional
carotenoid ketolase, leading to the accumulation of zeaxanthin rather
than to its downstream ketocarotenoid astaxanthin. Light irradiation,
glucose, NaCl, and nitrogen deficiency all induced CZ-<i>bkt</i>1 to accumulate zeaxanthin. CZ-<i>bkt</i>1 accumulated
zeaxanthin up to 7.00 ± 0.82 mg/g when induced by high-light
irradiation and nitrogen deficiency and up to 36.79 ± 2.23 mg/L
by additional feeding with glucose. Furthermore, in addition to zeaxanthin,
CZ-<i>bkt</i>1 also accumulated high amounts of β-carotene
(7.18 ± 0.72 mg/g or 34.64 ± 1.39 mg/L) and lutein (13.81
± 1.23 mg/g or 33.97 ± 2.61 mg/L). CZ-<i>bkt</i>1 is the sole species up to date with the ability to accumulate high
amounts of the three carotenoids that are essential for human health
Table_1_Investigating the shared genetic architecture between hypothyroidism and rheumatoid arthritis.docx
BackgroundThere is still controversy regarding the relationship between hypothyroidism and rheumatoid arthritis (RA), and there has been a dearth of studies on this association. The purpose of our study was to explore the shared genetic architecture between hypothyroidism and RA.MethodsUsing public genome-wide association studies summary statistics of hypothyroidism and RA, we explored shared genetics between hypothyroidism and RA using linkage disequilibrium score regression, ρ-HESS, Pleiotropic analysis under a composite null hypothesis (PLACO), colocalization analysis, Multi-Trait Analysis of GWAS (MTAG), and transcriptome-wide association study (TWAS), and investigated causal associations using Mendelian randomization (MR).ResultsWe found a positive genetic association between hypothyroidism and RA, particularly in local genomic regions. Mendelian randomization analysis suggested a potential causal association of hypothyroidism with RA. Incorporating gene expression data, we observed that the genetic associations between hypothyroidism and RA were enriched in various tissues, including the spleen, lung, small intestine, adipose visceral, and blood. A comprehensive approach integrating PLACO, Bayesian colocalization analysis, MTAG, and TWAS, we successfully identified TYK2, IL2RA, and IRF5 as shared risk genes for both hypothyroidism and RA.ConclusionsOur investigation unveiled a shared genetic architecture between these two diseases, providing novel insights into the underlying biological mechanisms and establishing a foundation for more effective interventions.</p

DOT1L inhibitor improves early development of porcine somatic cell nuclear transfer embryos
<div><p>Incomplete epigenetic reprogramming of the genome of donor cells causes poor early and full-term developmental efficiency of somatic cell nuclear transfer (SCNT) embryos. Previous research indicate that inhibition of the histone H3 K79 methyltransferase DOT1L, using a selective pharmacological inhibitor EPZ004777 (EPZ), significantly improved reprogramming efficiency during the generation of mouse induced pluripotent stem cells. However, the roles of DOT1L in porcine nuclear transfer-mediated cellular reprogramming are not yet known. Here we showed that DOT1L inhibition via 0.5 nM EPZ treatment for 12 or 24 h significantly enhanced the blastocyst rate of SCNT embryos and dramatically reduced the level of H3K79me2 during SCNT 1-cell embryonic development. Additionally, H3K79me2 level in the EPZ-treated SCNT embryos was similar to that in <i>in vitro</i> fertilized embryos, suggesting that DOT1L-mediated H3K79me2 is a reprogramming barrier to early development of porcine SCNT embryos. qRT-PCR analysis further demonstrated that DOT1L inactivation did not change the expression levels of <i>DOT1L</i> itself but increased the expression levels of <i>POU5F1</i>, <i>LIN28</i>, <i>SOX2</i>, <i>CDX2</i> and <i>GATA4</i> associated with pluripotency and early cell differentiation. In conclusion, DOT1L inhibitor improved early developmental efficiency of porcine SCNT embryos probably via inducing the increased expression of genes important for pluripotency and lineage specification.</p></div

TSA treatment alone improves early developmental efficiency of SCNT embryos.
<p>SCNT embryos at the pronuclear stage were cultured in PZM-3 supplemented with 50 nM TSA for 24 h and embryos cultured in PZM-3 containing DMSO were served as NT control, then TSA and DMSO were washed out and embryos were cultured in fresh PZM-3 medium until day 7. The effect of HDACs inhibition on the proportion of embryos that reached the 2-cell stage within 48 h after activation <b>(A)</b>, proportion of embryos developing to the blastocyst stage (Day 7) <b>(B)</b> and total cell number per blastocyst <b>(C)</b> are shown. The experiment was repeated at least three times with 200 embryos per group. All the percentage data are expressed relative to the number of 1-cell embryos and are shown as mean ± S.E.M. Values with different superscripts across treatments indicate significant differences (<i>P</i> < 0.05).</p
