2020/7/30Background Cell-based tissue engineering represents a promising management for meniscus repair and regeneration. The present study aimed to investigate whether the injection of parathyroid hormone (PTH) (1-34) could promote the regeneration and chondroprotection of 3D printed scaffold seeded with bone marrow mesenchymal stem cells (BMSCs) in a canine total meniscal

Effects of the hot zone design during the growth of large

2016/10/15The bottom corner of the crucible is the position where the heat flux becomes highest, therefore it is necessary to add insulation blocks in this region to reduce the heat loss. Teng et al. [9], [10] added an insulation block to prevent heat loss from the heat exchanger block to the gap of the insulation cage, which resulted in an interface shape with lower deviation between the crystal edge

(E to H) SEM images of (E) HBMSCs seeded on the cancellous bone structure and HUVECs seeded on the Haversian canal with different diameters of (F) 1.6 mm, (G) 1.2 mm, and (H) 0.8 mm. ( I and J ) The proliferation activity of HBMSC, HUVEC, and cocultured HBMSC-HUVEC seeded on scaffolds with different (I) diameters and (J) numbers of Haversian canals after culturing for 1, 3, 7, and 14 days.

On the effects of the ocean on atmospheric CFC

This highlights the time-dependent influence of the ocean on atmospheric loss rates of CFC-11. If the ocean's role is ignored and a constant atmosphere-only lifetime is assumed, then inferring emissions from concentration changes for 2014 to 2016 compared to 2002 to 2012 would overestimate the unexpected emission of CFC-11 by 0.4 0.3 Gg ⋅ yr −1 (assuming a constant lifetime of 55 3

Designing of PLA scaffolds for bone tissue replacement

2017/10/16Background The primary objective of Tissue engineering is a regeneration or replacement of tissues or organs damaged by disease, injury, or congenital anomalies. At present, Tissue engineering repairs damaged tissues and organs with artificial supporting structures called scaffolds. These are used for attachment and subsequent growth of appropriate cells. During the cell growth gradual

Influence of the Testa on Seed Dormancy, Germination,

The testa of higher plant seeds protects the embryo against adverse environmental conditions. Its role is assumed mainly by controlling germination through dormancy imposition and by limiting the detrimental activity of physical and biological agents during seed storage. To analyze the function of the testa in the model plant Arabidopsis, we compared mutants affected in testa pigmentation and

The value of trophic interactions for ecosystem function:

However, most biodiversity–ecosystem function experiments focus on bottom-up processes governed by terrestrial plant communities, demonstrating that diversity is important for resource capture and ecosystem resilience [11–13].

However, the influence of calcium chloride on the seeded MSZW of L-arabinose by modifying the nucleation rate has not been proved yet. In this study, it was found that the seeded MSZW of L-arabinose decreases in the 2.0% calcium chloride-water system and increases in

Isolation of endothelial cells, pericytes and astrocytes from

2019/12/18For experiments with cells seeded at the bottom of the wells, ECs were added on the inserts 24 h after ACs or PCs seeding. The medium was changed every 2–3 days. The permeability tests were performed on day 7 after ECs seeding.

Cedar Creek Ecosystem Science Reserve

2021/4/23We choose to separate these communities from other wooded swamps and fens because of the influence of their sphagnum substrate. While not true 'ombrotrophic bogs' (only nutrient input coming from atmosphere and rain water), the luxuriant growth of sphagnum in these swamps and fens both lowers the pH and the compressed underlying sphagnum peat reduces the input of nutrients from

CTCF: insights into insulator function during development

Therefore, the molecular mechanism regulating the BX-C locus turns out not to be a simple insulation- or relief from insulation-based mechanism, but rather a complex picture is emerging. Complexity is in part caused by additional factors, such as polycomb group proteins, and also by the large number of genomic elements involved in the three-dimensional interaction (for a review, see Bantignies

Surface charge migration and dc surface flashover of

2017/1/11Epoxy-based model insulators were manufactured and fluorinated under a F 2 /N 2 mixture (12.5% F 2) at 50 C and 0.1 MPa for 15 min and 60 min. Surface charge accumulation and decay behavior were studied with and without dc voltage application.The effect of

Effect of surface modification of electrodes on charge

This effect and has an important influence on the insulation performance of the liquid []. Many researchers have attempted to control the impulse insulation properties of liquid dielectrics in terms of both the electrode material and its surface modification.

Coupling Cas9 to artificial inhibitory domains enhances

The limited target specificity of CRISPR-Cas nucleases poses a challenge with respect to their application in research and therapy. Here, we present a simple and original strategy to enhance the specificity of CRISPR-Cas9 genome editing by coupling Cas9 to artificial inhibitory domains. Applying a combination of mathematical modeling and experiments, we first determined how CRISPR-Cas9
