Proteins are prone to inactivation in aqueous solutions because chemical modification and aggregation usually occur, particularly at high temperature. This review focuses on the recent advance in practical application with amine compounds that prevent the heat-induced inactivation and aggregation of proteins. Coexistence of amine solutes, typically diamines, polyamines, amino acid esters, and amidated amino acid Read More

Microorganisms prefer to live in three-dimensional self-organized communities (biofilms), and this behavior provides microbial pathogens inhabiting various sites in the human body or on medical devices with survival advantages. In fact, pathogens in the biofilm stage exhibit up to a thousandfold more tolerance to conventional antimicrobial agents, and thus, they are difficult to eradicate and biofilms generated during acute infecti Read More

Urate oxidase is considered as an important therapeutic enzyme used to control hyperuricemia. In spite of widespread distribution in numerous (micro)organisms, active urate oxidase is absent in higher primates (humans and apes) due to gene mutations. Considering the therapeutic significance of urate oxidase, further understanding on the inactivation process of the enzyme during primate evolution is critical. This st Read More

As the principal active ingredient in the Chinese herb Tripterygium wilfordii Hook.F (TwHF), triptolide has been shown to have very strong antitumor properties. The trimethylation of lysine 4 on histone H3 (H3K4me3) has been proposed to promote gene expression, and the accumulation of H3K4me3 at the transcriptional start sites of oncogenes is involved in carcinogenesis. To identify the association between the reduction Read More

Estrogen is one of the most important signaling molecules which targets a number of genes. Estrogen levels regulate cell proliferation and a plethora of metabolic processes, which may interfere with a range of medical conditions and drug metabolism. The MCF7 breast cancer cell line, expressing the estrogen receptor α, is a well-studied model of cellular answer to estrogen. The aim of this study was to characterize tra Read More

Sugar rich diet induces inflammation and insulin resistance mainly through gut microbiota alteration. Gut microflora dysbiosis increases plasma lipopolysaccharide and reduces short chain fatty acids to impair the insulin signaling cascades by different molecular pathways to progress into diabetes. Chitosan based formulations have major significance in insulin delivery system due to their ability to protect the insulin from e Read More

Excessive use of pesticides in agriculture has resulted in contamination of water resources, air, soil and disruption of biogeochemical cycles. These compounds adversely affect humans and animal health, helpful soil microbes and crop production as well. Biodegradation of pesticides by microbes exists in a number of habitats like soil, sediments, surface, ground water, and sludge, etc. In the present study, efforts were made to de Read More

It is important to establish an easy-to-use therapeutic protocol for the emergency medical care of patients involved in radiation accidents to reduce the radiation-related casualties. The present study aimed to establish an optimum therapeutic protocol using currently approved pharmaceutical drugs to increase the survival of victims exposed to lethal radiation. Different combinations of four drugs-recombinant human erythropo Read More

Mammalian cells are involved in a range of biotechnological applications and more recently have been increasingly exploited in regenerative medicine. Critical to successful applications involving mammalian cells are their long-term storage and transport, for which cryopreservation in liquid nitrogen is the most frequently used strategy. However, cryopreservation suffers from high costs, difficulties in transport logistics a Read More
