Soybean is one of the most important crops grown across the globe. In the United States, approximately 15% of the soybean yield is suppressed due to various pathogen and pests attack. Sudden death syndrome (SDS) is an emerging fungal disease caused by Fusarium virguliforme. Although growing SDS resistant soybean cultivars has been the main method of controlling this disease, SDS resistance is p...

Because V3 loop-specific antibodies have been shown to inhibit human immunodeficiency virus type 1 (HIV-1) infection of human cells and because specific mutations in the V3 loop render the virus ineffective for infection and syncytium formation, we tested the anti-HIV effects of V3 loop peptides from different HIV-1 strains. We obtained evidence that V3 loop synthetic peptides of 8 to 15 amino ...

PURPOSE Ocular surface and corneal epithelial wounds are common and potentially debilitating problems. Ideal treatments for these injuries would promote epithelial healing without inflammation, infection and scarring. In addition the best treatments would be cost-efficient, effective, non-toxic and easily applied. Histatin-1 peptides have been shown to be safe and effective enhancers of epithel...

Islet amyloid polypeptide, also known as amylin, is the main component of the amyloid deposits present in approximately 90% of people with type 2 diabetes mellitus (T2DM). In this disease, amylin aggregates into multimeric β-pleated sheet structures which cause damage to pancreatic islet β-cells. Inhibitors of early-stage amylin aggregation could therefore provide a disease-modifying treatment ...

BACKGROUND Cell-penetrating peptides (CPPs) have been widely used as carriers to transport different molecules into living cells, whereas messenger RNAs (mRNAs) have been utilized as target molecules for the prevention and treatment of various diseases. However, the instability of CPPs and mRNAs has limited their application. Bacteriophage PP7 virus-like particles (VLPs) may protect peptides an...

Alpha-bungarotoxin (alpha-BTX) is a highly toxic snake neurotoxin that binds to acetylcholine receptor (AChR) at the neuromuscular junction, and is a potent inhibitor of this receptor. In the following we review multi-phase research of the design, synthesis and structure analysis of peptides that bind alpha-BTX and inhibit its binding to AChR. Structure-based design concomitant with biological ...

Plasmon-assisted effects were used in this work to study the dynamical behavior of amyloid ? peptides (A?), particular A?(25–35), on silver nanoparticles. Amyloid derive from proteolytic cleavage glycoprotein named precursor protein (APP). A?(25–35) represents sequence that concentrates biological active region all peptide family, being shortest fragment A? retains toxicity full length. The pla...

The accumulation of toxic metals and metalloids, such as cadmium (Cd), mercury (Hg), or arsenic (As), as a consequence of various anthropogenic activities, poses a serious threat to the environment and human health. The ability of plants to take up mineral nutrients from the soil can be exploited to develop phytoremediation technologies able to alleviate the negative impact of toxic elements in...
