When parts or the whole of certain tissues or organs fail, there are several options for treatment, including repair, replacement with a synthetic or natural substitute, or regeneration. The fabrication of cell scaffold with hydrogel that derived from natural polymer materials is an attractive method to be applied for the tissue engineering, but some undesirable mechanical properties and...

Modern healthcare would not be possible without the usage of many polymer-based medical products. Many things we take for granted such as exam gloves, syringes, intravenous (IV) blood bags and even most artificial organs, etc. are all made of polymers. Due to their unique advantages of light weight, transparency, barrier properties, low cost and durability, polymer materials are very suitable...

Introduction to Acaricides Acaricides are a class of chemicals used to control herbivorous mites. The pest mites have the characteristics of small size, wide range of activities, strong reproductive ability, short life cycle and strong drug resistance, which can seriously reduce the yield of many important economic crops, and are recognized as one of the biological groups that are difficult to...

It is often difficult for a single polymer material to meet the material performance requirements of the production or research, polymer composite materials, therefore, have received extensive attention in both academia and manufacturing industry. Composites not only maintain the main characteristics of raw materials, but often have novel characteristics that raw materials do not have. By...

Coumarin, also known as bisfuran cyclooxaphthalone, is a lactone compound widely found in Rutaceae and Umbelliferae. Coumarin is a general term for a class of natural products with a benzo-αpyrone structure, which is widely used in medicine, fragrance, dyes, instrument analysis, agriculture and other fields. The drug molecules with coumarin and its derivatives as the basic skeleton have a...

Enzymes are extremely environmentally demanding and are particularly susceptible to external environmental influences and must be used under specific conditions in order to perform their functions. Liposomes are self-assembled lipid molecules, with one or more lipid bilayers with a biofilm-like structure surrounded by a microaqueous phase, which can be naturally occurring or synthetic and are a...

Background Nematodes belong to the class Nematoda of the linear phylum of invertebrates. Plant parasitic nematodes in plants and soils are characterized by small size, short life cycle, many species, extremely fast reproduction, wide distribution and difficult identification of damage symptoms. They are one of the main pathogens of plant invasive diseases. Compared with pathogens such as fungi,...

Chromatography-Chromatographic Hyphenated Technology High performance liquid chromatography (HPLC) is an important method for separating and analyzing mixtures of complex organics, drugs and biological macromolecules. As a modern analytical technique, the application of high performance liquid chromatography has become more and more extensive. When the sample composition is relatively simple,...

D-Lin-MC3-DMA is useful for design of lipid nanoparticles for in vitro and in vivo delivery of plasmid DNA. LNP systems containing D-Lin-MC3-DMA can be highly effective, non-toxic pDNA delivery systems for gene expression both in vitro and in vivo. Dengue virus is a ssRNA+ flavivirus, which produces the dengue disease in humans. Currently, no specific treatment exists. siRNAs regulate gene...

Moxidectin is an anthelmintic drug which kills parasitic worms (helminths), and is used for the prevention and control of heartworm and intestinal worms. Moxidectin can be used to prevent heartworm infection in dogs. Moxidectin is a semisynthetic derivative of nemadectin which is produced by fermentation by Streptomyces cyano-griseus. A range of blank, fortified, incurred and control liver...
