Furthermore, qPCR results revealed that lower expression of miR-1-3p in NPB could increase the expression of LXRα, which is an enzyme important for the synthesis and accumulation of lipid. The double luciferase report experiment suggested that LXRα was the direct target gene of miR-1-3p. In short, miR-1-3p could modulate the synthesis and accumulation of lipid by target LXRα. Aristolochic acid A cost It may be a potential marker for pig breeding.
Our investigation has delineated the different miRNAs expression patterns of LPB and NPB, which may help understand the regulatory mechanisms of miRNAs in the lipid metabolism, and provide potential biomarkers for Neijiang pig breeding.

Most fractures could heal after treatment, around 5-10 % of patients still develop delayed union and nonunion. Evidence has increasingly shown that abnormal expression of long noncoding RNAs is closely related to the occurrence and development of various diseases including fracture healing. However, evidence regarding the effect of MALAT1 on fracture healing remains limited.
In this study, we attempt to explore the role of MALAT1 during the process of femoral neck fracture healing and elucidate the underlying mechanism of this disease.
We first detect the expression of lncRNAs in serums from 3 pairs of patients with delayed femoral neck fracture healing and healthy volunteers using lncRNA microarray. And the expression of long noncoding RNA MALAT1 in serums and LPS-treated MG-63 cells was measured using qRT-PCR. CCK-8 assay, cell migration and qRT-PCR were applied to the role of MALAT1 knockdown in LPS-treated MG-63 cells. ELISA was used for the measurement of inflammatory cytokines in serums of patients and healthy volunteers. The bioinformatics analysis and the rescue experiment were devoted to the underlying mechanism.
MALAT1 expression was up-regulated in serum of patients with delayed union of femoral neck fracture. MALAT1 knockdown promoted cell viability and migration, reduced inflammation in LPS-treated MG-63 cells. The bioinformatics analysis showed MALAT1 acts as a molecular sponge for miR-212. And SOX6 was a target of miR-212. Besides, MALAT1 knockdown suppressed SOX6 expression via targeting miR-212 in LPS-treated MG-63 cells.
These data suggest MALAT1 knockdown promoted the biological behavior of LPS-treated MG-63 cells via sponging miR-212, which may provide a new therapeutic avenue for delayed union of femoral neck fracture.

In persons with type 1 diabetes (T1D) insulin dosing can be adjusted based on trend arrows derived from continuous glucose monitoring (CGM). We propose a slide rule with narrower blood glucose intervals and more classes of insulin sensitivity than are available in current models.
The slide rule was tested in silico, in which a meal was simulated in 100 virtual subjects and the insulin bolus was calculated either in the standard way based on the insulin-to-carbohydrate ratio and the correction factor or according to the slide rule, following which the percentage time spent in range (70-180mg/dl; %T
), hypoglycemia (< 70mg/dl; %T
), and hyperglycemia (> 180mg/dl; %T
) was compared between the methods during the 4h after the meal. Slide rule performance was also tested in real life by analyzing the same variables at during the 4h postprandial period in 27 individuals with T1D. Only meals starting while the rate of change was at least 1mg/dl per minute (increasing or decreasing) were considered for analysis.
In silico, when the preprandial trend arrow was increasing, our slide rule reduced %T
and increased %T
(p < 0.05), whereas when the preprandial trend arrow was decreasing, it reduced %T
and slightly increased %T
(p < 0.05). In real life, our slide rule kept subjects on target for 70.8 and 91.6% of postprandial time when preprandial trend arrows were increasing or decreasing, respectively.
The proposed slide rule performed well both in silico and in real life, suggesting that it could be safely adopted by individuals with T1D to improve glucose control.

Through ultraviolet absorption spectroscopy and fluorescence emission spectroscopy experiments, it was confirmed that these two compounds exhibited good aggregation-induced emission (AIE) behavior in ethanol/water mixtures. The solvent effect test showed with the increase of the orientation polarizability of the solvent, the Stokes shift in the solvent of compound 1 and compound 2 shows a linear change trend. Through solid state fluorescence test and universal density function theory (DFT), the existence of π-π stacking interaction in the solid state of the compound has been studied, resulting in weak fluorescence emission. pH has no effect on the fluorescence intensity of the aggregate state of excited state intramolecular proton transfer (ESIPT) molecules in an acidic environment, but greatly weakens its fluorescence intensity in an alkaline environment. Cyclic voltammetry (CV) test shows that compound 1 was more prone to oxidation reaction than compound 2. The results of thermal stability test show that the thermal stability of compound 1 was better than that of compound 2, indicating that triphenylamine chalcone derivatives can improve the thermal stability of compounds by increasing the number of branches.
Is it possible to eliminate metastasised chronic myeloid leukaemia (CML) and acute myeloid leukaemia (AML) cells from ovarian cortex fragments by inhibition of Aurora B/C kinases (AURKB/C) without compromising ovarian tissue or follicles?
Human ovarian cortex tissue with experimentally induced tumour foci of CML, AML and primary cells of AML patients were exposed to a 24h treatment with 1μM GSK1070916, an AURKB/C inhibitor, to eliminate malignant cells by invoking mitotic catastrophe. After treatment, the inhibitor was removed, followed by an additional culture period of 6days to allow any remaining tumour cells to form new foci. Ovarian tissue integrity after treatment was analysed by four different assays. Appropriate controls were included in all experiments.
Foci of metastasised CML and AML cells in ovarian cortex tissue were severely affected by a 24h ex vivo treatment with an AURKB/C inhibitor, leading to the formation of multi-nuclear syncytia and large-scale apoptosis. Ovarian tissue morphology and viability was not compromised by the treatment, as no significant difference was observed regarding the percentage of morphologically normal follicles, follicular viability, glucose uptake or in vitro growth of small follicles between ovarian cortex treated with 1μM GSK1070916 and the control.
