BACKGROUND In the treatment of human head lice infestation, healthcare providers are increasingly concerned about lice becoming resistant to existing pesticide treatments. Traditional pesticides, used to control these pests, have a neurological mechanism of action. This publication describes a topical solution with a non-traditional mechanism of action, based on physical disruption of the wax l...

The severe acute respiratory syndrome coronavirus 2, better known as COVID-19, has become a major health concern worldwide. It challenged the global healthcare sector like anything. appeared in Wuhan, China, around November 2019, had spread to almost 187 countries due its highly contagious nature. Quarantine, isolation, mask, and other precautionary measures remain sole obliging strategy declin...

In intact, but not in permeabilized, human erythroid progenitor cells, thrombin and phorbol esters potentiate cellular cAMP formation in response to Gs-coupled receptor agonists such as prostaglandin E1 (PGE1). We show here that the two agonists achieve their phenotypically similar effects by using distinctly different signaling pathways, both of which require protein kinase C (PKC) activation....

The flowers of Canada thistle, Cirsium arvense (L.), attract a wide range of insects, including pollinators and herbivorous species. This attraction is primarily mediated by floral odor, which offers potential for developing generic insect attractants based on odor. In this study, we have analyzed the chemical composition of the volatiles produced by Canada thistle flowers. Nineteen floral comp...

BACKGROUND Cyanobacterial mutants engineered for production of free fatty acids (FFAs) secrete the products to the medium and hence are thought to be useful for biofuel production. The dAS1T mutant constructed from Synechococcus elongatus PCC 7942 has indeed a large capacity of FFA production, which is comparable to that of triacylglycerol production in green algae, but the yield of secreted FF...

The aim of this study was to develop a microemulsion system as a medium for laccase-catalyzed reactions. Phase behavior studies were conducted by constructing partial pseudo-ternary phase diagrams for systems comprising of cetyltrimethylammonium bromide (CTAB), various organic solvents as the oil phase (i.e., hexane, cyclohexane, heptane, octane, isooctane, toluene, isopropyl myristate), two co...
