Development of polyvinyl alcohol/carrageenan hydrogels and fibers via KOH treatment for Morse code information transmission.

To solve the inherent problems of conductive hydrogels, such as relatively low mechanical properties and fatigue resistance, inability to work after water loss, and difficulty weaving. In this study, the borax-crosslinked polyvinyl alcohol/k-carrageenan (kC) conducting hydrogels (BPK) were prepared by a simple one-pot method, and KOH treatment was used instead of the cumbersome and time-consuming freeze-thaw cycle to improve the comprehensive properties. The KOH treatment increased the hydrogel hydrogen bonding content by 7.

Low-temperature superelastic, anisotropic, silane-crosslinked sodium alginate aerogel for thermal insulation.

Bio-aerogels have attracted much attention owing to their remarkable properties, but their brittle and poor elasticity has limited their further applications. Here, we propose a strategy of in-situ silanization crosslinking combined with unidirectional freeze casting (SUFC) to prepare superelastic sodium alginate (SA) aerogels. The resulting aerogel was ultra-light (0.

Rucaparip (Rubraca) induces necrosis via upregulating the expression of RIP1 and RIP3 in ovarian cancer cells.

In the current study we investigated the inhibitory effect of rucaparib (Rubraca) on human ovarian cancer SKOV3 and A2780 cells and its possible mechanism. Cancer cells and human normal ovarian epithelial IOSE80 cells were treated with Rubraca at different concentrations. Cell viability was measured by MTT assay.

Loss of heterozygosity in thyroid hormone receptor beta in invasive breast cancer.

Background: Loss of heterozygosity (LOH) on chromosome arm 3p, where the gene of thyroid hormone receptor beta (THRB) is located, has been reported in breast cancer. Although some studies performed in vitro have suggested that THRB could act as a tumor suppressor in breast cancer development, there is still no unequivocal evidence to support this.

Methods: To determine the role of LOH in breast tumor development, the LOH of THRB and its proximal microsatellite markers D3S1293, D3S3659, D3S3700, D3S2307 and D3S2336 was investigated in a genomic region spanning ~3.

[Study on structural properties of biochar under different materials and carbonized by FTIR].

Infrared spectroscopy (IR) is an important means of seeing the characteristics of the structural properties. Fourier transform infrared spectroscopy (FTIR) was applied to analyze the structural properties of biochar from different materials with different methods. The results showed that: the biochars have IR absorption peaks of hydroxyls group, aromatic group and containing organic group with the activated? charcoal, but in other absorption peaks, with a significant difference.

Cytogenetic analysis of human bone marrow-derived mesenchymal stem cells passaged in vitro.

This study concerns the cytogenetic stability of in vitro human bone marrow-derived mesenchymal stem cells (MSCs) in primary culture and after passaging. Bone marrow samples were collected from seven brain malfunction patients involved in autologous MSC transplantation trials. Chromosome preparations from primary MSC cultures and after 3 passages were analyzed by conventional staining and G-banding techniques.
