Influenza A viruses, the culprits of respiratory illness in humans, are a complex and multifaceted group of viruses. Among the numerous subtypes of Influenza A, H1N1 and H3N2 with a notorious history of causing seasonal epidemics and pandemics, demand special attention. Figure 1. The Spread of Influenza A. Influenza A H1N1, also known as the swine flu, is a formidable subtype […]

What are polyacrylates nanoparticles? Polyacrylates are an important class of soft, tough and rubbery polymers, which are known for their high transparency, good impact toughness and elasticity. Polyacrylates and their copolymers are one of the polymeric nanoparticles (NPs). Polymeric nanoparticles are particles within the size range from 1 to 1000 nm and can be loaded with active

Introduction Malaria is caused by infection with Plasmodium parasites. Plasmodium belongs to unicellular eukaryote, and the Plasmodium that infects human body mainly comprises 5 kinds: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi. Among them, Plasmodium falciparum and Plasmodium vivax are the most widespread in the global epidemic area, and Plasmodium falciparum is

Registered nurses (RNs) often need to deal with an occupied and requesting workload, especially in medical care settings such as hospitals, clinics, and long-term care facilities. Here are some methodologies that RNs use to effectively manage their responsibility :   Prioritizing: Registered nurses (RNs) survey the urgency and importance of tasks and prioritize them accordingly.

Pectin is a hydrophilic vegetable gum. Widely present in the fruits, roots, stems and leaves of higher plants, it is a component of the cell wall. The pectin content of different plants or different parts of the same plant varies greatly. So far, only a few plants with high pectin content have been found and used

Cytotoxicity testing is a sensitive method to assess the biocompatibility of a material extracted through a specific cell culture media following exposure of the extracted fluid to L929 cells. This test is performed on raw materials in the manufacturing process, all medical devices contacting patients, and devices undergoing a sterilization validation. STEMart provides a wide range

Nucleic acid is the main material for storing, copying, and transmitting genetic information. Nucleic acid extraction is one of the most fundamental steps in molecular biology applications and is a prerequisite for many experiments. The quality of extracted nucleic acid will directly affect the results of subsequent detection in experiments. Traditional nucleic acid extraction methods

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by bilateral motor (eg, bradykinesia, resting tremor, postural instability, rigidity) and nonmotor (eg, memory loss, depression) disability. About 10 million people worldwide suffer from Parkinson’s disease. Current PD treatments are limited to motor symptom management, such as dopamine replacement therapy or enhancing the activity of remaining

After the host is infected by the virus, the immune system can generate a corresponding immune response. Antibodies specific to viral surface proteins produced at this time can often prevent the virus from adhering to the surface of host cells, making it incapable of infecting cells. However, in some cases, antibodies play the opposite role
