BACKGROUND Mosquitoes have developed resistance against pyrethroids, the only class of insecticides approved for use on long-lasting insecticidal nets (LLINs). The present study sought to evaluate the efficacy of the pyrethroid synergist PermaNet® 3.0 LLIN versus the pyrethroid-only PermaNet® 2.0 LLIN, in an East African hut design in Lower Moshi, northern Tanzania. In this setting, resistance ...

Tendon is a dynamic tissue whose structure and function is influenced by mechanical loading, but little is known about the fundamental mechanisms that regulate tendon growth and remodeling in vivo. Data from cultured tendon fibroblasts indicated that the p38 MAPK pathway plays an important role in tendon fibroblast proliferation and collagen synthesis in vitro. To gain greater insight into the ...

The motor pattern that drives each crayfish swimmeret consists of alternating bursts of impulses in power-stroke (PS) and return-stroke (RS) motor neurons. A model of the neural circuit that generates this pattern focused on connections between motor neurons themselves (Heitler, 1978, 1981). The model predicts that synergist motor neurons are electrically coupled, whereas antagonists make mostl...

the study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of urtica dioica l. (ud), malva neglecta wallr. (mn) plants and their mixture. in this study, flower (udf), root (udr), seed (uds) and leaf (udl) parts of ud and flower (mnf) and leaf (mnl) parts of mn were used. the antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

Abstract Intumescent flame retardants (IFR) are widely used in the field of retardant polypropylene (PP), but their efficiency and smoke suppression properties need to be further improved. Herein, a Ni‐Al LDH (layered double hydroxide) is obtained successfully by coprecipitation microwave hydrothermal technique as synergist improve flame‐retardant smoke‐suppression triazine‐based IFR. The resul...
