Polymeric Biomaterials (Mingyu Li z3369978) The use of polymers in biomedical applications is now widely accepted and they are termed with the generic name of polymeric biomaterials. A biomaterial can be defined by their function as a material in contact with living tissue that used to the treatment of disease or injury‚ and to improve human health by restoring the function of tissue and organs in the body.x Polymeric biomaterials in medicine include surgical sutures‚ drug delivery vectors‚ orthopedic

Introduction: 1 Vitamin D is critical for embryonic skeletal formation and long bone growth. Without vitamin D‚ the hypertrophic cell zone will expand because the cartilage fails to calcify leading to rickets. Protein disulfide isomerase A3 (PDIA3)‚ also known as ERp60‚ ERp57‚ Grp58‚ and 1‚25-MARRS‚ is a multifunctional protein that has been associated with rapid membrane-initiated signaling by 1α‚25-dihydroxyvitamin D3 (1α‚25(OH)2D3) in several cell types. Knockdown of PDIA3 in osteoblast-like

wastewater treatment plants is poor. Applying both culture-dependent and molecular methods to two ATAD systems in Victoria‚ Australia treating different wastewaters revealed that their communities were highly specialized. Denaturing gradient gel electrophoresis (DGGE) profiling suggested differences in their population compositions and both changed over time. However‚ both showed low level biodiversity‚ and contained several novel bacterial populations. 16S rRNA clone library data and FISH analyses

Biotechnology is one of the most exciting and amazing technologies this world has seen. Biotechnology is the use of living organisms or biological processes to develop useful agricultural‚ industrial‚ or medical products. In other words‚ biotechnology is the procedure of using organisms and their components to create useful things for humans. As a matter of fact‚ people are being aware of this new technology through different types of entertainment like movies‚ TV shows‚ and video games. As more

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique used in mass spectrometry‚ allowing the analysis of biomolecules (biopolymers such as DNA‚ proteins‚ peptidesand sugars) and large organic molecules (such as polymers‚ dendrimers and other macromolecules)‚ which tend to be fragile and fragment when ionized by more conventional ionization methods. It is similar in character to electrospray ionization both in relative softness and the ions produced (although it causes

The spot inoculation method was followed for antifungal activity of bacterial strain Paenibacillus elgii TS33 25. The nutrient agar medium was prepared‚ sterilized at 121ºC‚ poured into the sterilized peteriplates and allowed to solidify under aseptic conditions. After solidification bacterial strain Paenibacillus elgii TS33 was spot inoculated on nutrient agar medium and incubated at 37ºC for 48 hours. After incubation the molten potato dextrose agar medium containing the spores of test fungus‚

INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated
