Leading dermatology and plastic surgery experts note hollowing in the cheeks and under the eyes, laxity along the jawline and neck, and an overall decline in skin quality, terms often associated with Ozempic face.Clinicians emphasize that GLP-1 patients may require a different skin care strategy, with skin quality affected not only by volume loss but also by changes in collagen, elastin, and ...
One of MGP’s principal biological functions is the inhibition of hydroxyapatite deposition, the crystalline form of calcium phosphate found in bone. In soft tissues like arteries, unregulated hydroxyapatite accumulation leads to vascular calcification, a pathological condition associated with atherosclerosis, diabetes, chronic kidney disease (CKD), and ...
What is biofilm? Biofilms are defined as communities of micro-organisms attached to a surface, or one another, and encased within a matrix of extracellular polymeric substance (EPS). The EPS makes up the largest component of the biofilm, and in the biological environment is generally composed of polysaccharides, proteins, glycolipids, blood products, cellular debris, extracellular enzymes, metal ...
Cellular Sources of MMPs MMPs are produced by a variety of tissues and cells. MMPs are secreted by pro-inflammatory cells and uteroplacental cells, including fibroblasts, osteoblasts, endothelial cells, vascular smooth muscle, macrophages, neutrophils, lymphocytes, and cytotrophoblasts. ...
Uses of Recombinant Human Collagen Due to its good biocompatibility, low immunogenicity, stabilized property, recombinant human collagen has been widely used in tissue engineering (such as vascular scaffolds engineering, cartilage, bone defect repair), skin injury treatment, drug delivery, etc. [1]. Tissue engineering The production of ...
The printer can be programmed to create precise and intricate structures, mimicking the complex architecture of natural tissues. Once printed, the cells in the bio-ink are carefully nurtured in a controlled environment to allow them to grow and mature into functional tissue. ...

We have developed a tissue-engineered human acellular vessel (HAV) that can be manufactured, stored on site at hospitals, and be immediately available for arterial vascular reconstruction. ...
Abstract : Intimal hyperplasia is one of the prominent failure mechanisms for arteriovenous fistulas and arteriovenous access grafts. Human tissue-engineered vascular grafts (TEVGs) were implanted as arteriovenous grafts in a novel baboon model. ...
In addition, significantly more bacteria were recovered from explanted ePTFE compared to HAV. Gram staining of explanted tissue sections revealed interstitial bacterial contamination within ePTFE, whereas no bacteria were identified in HAV tissue sections. ...
Thus, it is imperative to develop a tissue engineered vascular graft by mimicking the native endothelium to provide the best possible environment, thereby enhancing clinical patency. The success of a tissue engineered graft depends largely on its ability to replicate the microenvironments in the native tissue. ...
NovoSorb® BTM (Biodegradable Temporizing Matrix) is a biodegradable temporizing dermal matrix designed to aid the body in regenerating new tissue for wound closure and reconstruction of complex wounds. NovoSorb BTM is a fully synthetic bilayer open-cell matrix that acts as a scaffold and is designed to facilitate the growth of a fully vascularized dermal ...

Surgical reconstruction of PSD lesions typically uses a tissue flap that is ‘freed’ from the surrounding tissue, then advanced over the wound to provide immediate closure. However, this approach is often compromised by the poor tissue quality that can lead to post-operative surgical complications (e.g. dehiscence – ...
Additionally, we have learned that the delivery of oxygen to the tissues is not something that happens immediately upon creation of the arteriovenous communication; rather, it takes several weeks for the arterialized venous flow to deliver oxygenated blood to the tissue. ...
The next great symbiotic relationship for humans could be between fabricated tissues and pond scum. Allevi Authors at Harvard Medical School and Brigham and Women’s Hospital recently published their findings on the use of algae in tissue engineering. ...
As I performed my manual lymphatic drainage techniques, I did use the diathermic effect of the capacitive electrode to dilate lymph vessels and vascular tissue proximal to the injury so that fluid drained from the surgical site would have an easier time of moving out. ...
Histopathologic evaluation of implanted BTLT and underlying host tissue revealed integration of the fabricated tissues with the underlying host liver, with the implanted graft having defined areas of parenchymal and non-parenchymal (NPC) zones. ...
Tissue engineering small diameter vascular grafts requires excessive culture times to produce an appropriate extracellular matrix (ECM). ...
