Identification of a suitable sterilisation method for collagen derived from a marine Demosponge
Collagen is widely used as a biomedical material, and its importance is likely to grow as research and understanding progresses in this field. As a biomedical material, ensuring the sterility of collagen before use as, or incorporation into, a medical device is paramount. However, common sterilisation techniques can induce changes in the physical structure and protein chemistry of collagen, ...

How to Choose Transparency and High-Performance Insole Silicone Insole?
The silicone insole is a kind of liquid silica collagen material specially used for making insoles. The same product has PU insoles! Of course, although PU insole is a little similar to silicone insole, the feel effect is completely different! If we want to make a silicone insole with good pulling force, high transparency and strong performance, we need to choose a high-quality silicone collagen ...

Adsorption of anionic dyes on Fe(III)-loaded collagen fibre from aqueous solution
A novel adsorbent, Fe(III)-loaded collagen fibre (FLCF), was prepared and its adsorption behaviours to three kinds of anionic dyes, Direct Yellow 11 (DY11), Acid Yellow 11 (AY11) and Reactive Blue 19 (RB19), were investigated. It was found that the highest adsorption capacity appeared at pH 3 and that the effect of temperature was not remarkable on the adsorption of AY11 and RB19, whilst ...

What Is Collagen?
Collagen is a family of proteins. At least 30 kinds of genes encoding collagen chains have been found, which can form more than 16 kinds of collagen molecules. According to its structure, it can be divided into fibrous collagen, basement membrane collagen, microfibrillar collagen, anchored collagen, hexagonal reticular collagen, non-fibrous collagen, transmembrane collagen, etc. According to ...

Development of fabrication technique in nano–scale resveratrol by collagen
Resveratrol (3,5,4′–trihydroxy–trans–stilbene, RSV), is found in various plants, including grapes, berries and peanuts. It is also present in wines, especially red wines. RSV has potent antioxidant, anti–inflammatory, and chemo–protective properties used as a biologically active supplement in the prophylaxis of myocardial infarction, diabetes, and tumours. The aim of this study was using ...

Uses of Recombinant Human Collagen
Collagen is the main structural protein in vertebrates. It plays an essential role in providing a scaffold for cellular support and thereby affecting cell attachment, migration, proliferation, differentiation, and survival. Natural animal collagen and its recombinant collagen are favorable replacements in human tissue engineering due to their remarkable biomedical property. However, this ...

L-sox5 and sox6 drive expression of the aggrecan gene in cartilage by securing binding of sox9 to a far-upstream enhancer
The Sry-related high-mobility-group box transcription factor Sox9 recruits the redundant L-Sox5 and Sox6 proteins to effect chondrogenesis, but the mode of action of the trio remains unclear. We identify here a highly conserved 359-bp sequence 10 kb upstream of the Agc1 gene for aggrecan, a most essential cartilage proteoglycan and key marker of chondrocyte differentiation. This sequence directs ...

Electrospinning Technology of Recombinant Human Collagen
Electrospinning can produce continuous fibers on the micro - and nano-scale. The high flexibility and low cost of the material make electrospinning very attractive. In addition, the high specific surface area, porosity, and similarity to ECM ensure that the electrostatic pad promotes cell adhesion, skin regeneration, nutrient and oxygen transport, moisture retention, exudate removal, and ...

Endoform improves wound closure for Diabetic Foot Ulcers
Highlights A retrospective analysis of real-world data published in the ‘International Wound Journal’ compared the wound closure times for diabetic foot ulcers treated with either Endoform™ Natural (1150 wounds) or collagen/ORC (1072 wounds). The data was analyzed to evaluate the median time for wound closure, percentage of wounds healed at 12-,24- and 36- weeks and ...

Effects of diluted bitumen exposure on juvenile sockeye salmon: From cells to performance
Diluted bitumen (dilbit; the product of oil sands extraction) is transported through freshwater ecosystems critical to Pacific salmon. This is concerning, as crude oil disrupts cardiac development, morphology, and function in embryonic fish, and cardiac impairment in salmon can have major consequences on migratory success and fitness. Yet the sensitivity of early life‐stage salmon to dilbit ...

Let red light put your salon in the green
Who amongst us wouldn't turn back the clock if we could - especially when it comes to our skin? It turns out: You now can... in a manner of speaking. Red light is a healing strategy that has been proven in scientific studies and product tests to stimulate production of collagen, which improves the appearance of skin, making you look years younger. Repeated tests show red light therapy is an ...

How Much Do You Know about Cocklebur Plant?
What is Cocklebur? Xanthium strumarium is a flowering plant belonging to the Asteraceae family. It is an annual herb known for its rough, oval spines covered in hooked spines. These burrs easily attach to clothing, fur, and feathers, allowing the plant's seeds to disperse over long distances. It is considered a noxious weed in some areas due to its toxicity and impact on agriculture. The seeds ...

New findings! Egr1 is a target for the treatment of fibrotic nephropathy
Epigenetic modifications play a crucial role in various biological processes and diseases, and DNA methylation is an important mechanism of epigenetic inheritance. DNA methyltransferases (DNMT1, DNMT3a, and Dnmt3b) are involved in the generation and maintenance of the epigenome. Specifically, DNMT3a and Dnmt3b are responsible for establishing DNA methylation, whereas DNMT1 maintains ...

Differential effects of abaloparatide and teriparatide on hip cortical volumetric BMD by DXA-based 3D modeling
Abstract In postmenopausal osteoporotic women in ACTIVE, abaloparatide reduced fracture risk and increased areal bone mineral density (BMD) more than teriparatide at the hip and wrist. DXA-based 3D modeling showed significantly greater increases in hip cortical volumetric BMD with abaloparatide versus teriparatide. This may explain differences reported in aBMD by DXA. Introduction: In ...
