Life at all costs: European precautionary policies on xenotransplantation
Xenotransplantation is becoming an independent political and regulatory issue. Most national regulations and international recommendations prescribe a precautionary approach, including strict monitoring and surveillance of patients. This is due to the risk of xenosis, a disease induced by non-human biological material. The paper shows how the precautionary approach violates fundamental principles ...

Being a member of the club: the transnational (self-)governance of networks of biobanks
Biobanks have become one of the core resources for biomedical research. At the same time, a number of risks associated with processing and storing of biological material and corresponding data have been diagnosed. This paper focuses on how institutionalised transnational networks of biobanks generate practical answers to some of these risks. Drawing upon three case studies – GenomEUtwin, ...

Bacterial synthesis of nanostructured hydroxyapatite using Serratia marcescens PTCC 1187
Nanostructured hydroxyapatite (nHA) exhibits improved mechanical properties and biocompatibility. To optimise the benefits of nano-sized precursors, the particles must have a uniform shape and size and minimum degree of agglomeration. In this study nHA was synthesised using an Iranian strain of Serratia. The powder was synthesised in different pH of reaction solution and incubation temperatures. ...

Polymer material in 3D Printing
With its unique manufacturing technology, 3D printing allows us to produce unprecedented types of items. However, the real advantage of 3D printing technology lies in its printing materials. Only by developing more new materials can the application fields of 3D printing technology be expanded. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber ...

Multifunctional Black Bioactive Ceramic Material Developed Recently
Bioceramic materials have a long history of being used to repair human hard tissues, from biologically inert materials (such as alumina and zirconia, etc.) to biological materials that are both biologically active and degradable (such as phosphate and silicate bioceramics, silicon Based bio-glass, etc.), its physiological function is no longer a simple tissue filling substitute, but a tissue ...

A Brief Introduction to Functional PEGs
Due to its biological inertness and good biocompatibility, polyethylene glycol (PEG) has a wide range of applications in the pharmaceutical industry, biological materials, cosmetics, and analytical science. A number of compounds, such as proteins, peptides, oligonucleotides, drugs and liposomes, after being modified by PEG covalent bonding, can effectively extend the circulation time in the body, ...

Biopharma PEG Provides Multi-arm PEG Derivatives Crosslinked Into Hydrogels
Polyethylene (ethylene glycol) is a hydrophilic polymer that can have a very high water content when cross-linked into a network. Polyethylene glycol (PEG) is a suitable material for biological applications because it does not normally elicit an immune response. Since the 1970s, PEG has been used to modify therapeutic proteins and peptides in order to increase their solubility, reduce their ...

What is a Liquid Nitrogen Storage Tank and What is it Used for?
A liquid nitrogen (LN2) storage tank is typically a multi walled vessel which features a high vacuum between the walls to provide excellent thermal insulation. Such vessels are often used in cold chain storage and transport applications. When the vessel is used to store or transport cryogenic liquids (such as liquid nitrogen or liquid helium) only, then the vessel is known as a liquid nitrogen ...

Nanobiotechnology approaches for targeted delivery of pharmaceutics and cosmetics ingredients
Nanobiotechnology refers to the ability to create and manipulate biological and bio-chemical materials, devices, and systems at atomic and molecular levels. Nano delivery systems hold great potential to overcome some of the obstacles in bio-pharmaceutical production, such as water soluble/insoluble pharmaceutical drugs and cosmetic ingredients, risks of toxicity, increasing bio-active efficacy, ...

7 Advantages of NovoSorb BTM
Complex wounds often involve exposed deep structures of the dermal layer, requiring prompt wound closure and tissue reconstruction. It is essential to quickly assess the defect and identify the most effective treatment method for optimizing the patient’s experience and outcome. Often, dermal substitutes are selected as a surgical option for temporizing the wound bed while also facilitating ...

What Is Drug Stability Analysis? - Basics You Need to Know in Drug Discovery
The basic requirements of pharmaceutical preparations are safety, efficacy, and stability. Drug stability means that a drug product should maintain the same properties and characteristics as it was at the time of production and within the specified time frame. The stability of pharmaceutical preparations directly affects the effectiveness and safety of drugs. Therefore, it is of great ...

Chinese company implants 3-D printed blood vessels into monkeys
Beijing, China (CNN)A major breakthrough in 3-D printed medicine could bring hope to nearly 1.8 billion patients with cardiovascular disease. Chinese scientists working for Sichuan Revotek have successfully 3-D printed blood vessels and implanted them in rhesus monkeys, the company said. It is a major step on the road to mass printing human organs for transplants. The company ...

Essential Facts about NovoSorb BTM
When trauma to the skin occurs, large areas of both the skin’s surface (epidermis) and deeper layers (dermis) may be destroyed. In many cases, large full-thickness wounds may require temporization due to the lack of suitable donor sites for primary skin grafting. Clinical research[1] indicates the temporization of deep, large wounds with dermal scaffolds can not only help provide ...

Surgical management of an infected external iliac artery interposition graft with a bioengineered human acellular vessel
ABSTRACT Infection of prosthetic vascular grafts can manifest as pain, pseudoaneurysms, or arterial insufficiency in the leg. We present the case of a female patient with a medical history of a right external iliac artery endofibrosis, with a persistently infected synthetic iliofemoral bypass graft, which we replaced with a bioengineered human acellular vessel. At the 12-month follow-up visit, ...

Infectious Pancreatic Necrosis (IPN)
Cause of the Disease Infectious pancreatic necrosis (also known as Acute catarrhal enteritis) is one of the first described and most extensively studied diseases of fish. There are strains and substrains of IPN virus that can be differentiated by serological, biochemical and genetic means. The VR-299 (type 1) strain was originally isolated in North America and has since been found almost ...

Diamond coated microtools for machining compact bone
The structure of compact bone is heterogeneous and as such, is difficult to shape by cutting tools during clinical surgical practices. The structure of bone can have a devastating effect on the performance of the cutting tool unless it is coated with a thin solid film that is wear resistant. The paper investigates the use of diamond coated cutting tools to prepare bone for prosthetic implants and ...
