Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

Cytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Establishing the resistance of Myzus persicae (Sulzer) by molecular methods [PDF]

Archives of Biological Sciences, 2008
In two years of investigating resistance of the peach-potato aphid Myzus persicae (Sulzer) by molecular methods, several types of resistance were established in the majority of individuals from peach and tobacco in Serbia and Montenegro.

Bioactive Magnesium Silicate Activating Myocardial Energy Metabolism For Infarcted Myocardium Repair

Exploration, EarlyView.
ABSTRACT The heart is a highly energy‐dependent organ, developing bioenergy‐activating biomaterials to activate myocardial adenosine triphosphate (ATP) production and restore dysregulated energy homeostasis is a promising solution for its functional recovery.

Multiple insecticide resistance in Anopheles gambiae from Tanzania: a major concern for malaria vector control

Malaria Journal, 2017
Background Malaria vector control in Tanzania is based on use of long-lasting insecticide treated nets (LLINs) and indoor residual spraying (IRS), which both rely on the use of chemical insecticides. The effectiveness of these control tools is endangered

Absence of knockdown mutations in pyrethroid and DDT resistant populations of the main malaria vectors in Colombia

Malaria Journal, 2019
Background Knockdown resistance (kdr) is a well-characterized target-site insecticide resistance mechanism that is associated with DDT and pyrethroid resistance.

Status of insecticide resistance and its biochemical and molecular mechanisms in Anopheles stephensi (Diptera: Culicidae) from Afghanistan

Malaria Journal, 2019
Background Insecticide resistance of Anopheles stephensi, the main malaria vector in eastern Afghanistan, has been reported previously. This study describes the biochemical and molecular mechanisms of resistance to facilitate effective vector control and

α2,3‐Sialyltransferase (ST3Gal1) regulates endometrioid‐type epithelial ovarian cancer cell migration and invasion via VEGF‐R2/JAK2/STAT3 signaling cascades

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the role of ST3 β‐galactoside α‐2,3‐sialyltransferase 1 (ST3Gal1) and vascular endothelial growth factor receptor 2 (VEGF‐R2) in endometrioid‐type epithelial ovarian cancer (E‐OC) because aberrant α2,3‐sialylation mediated by ST3Gal1 and VEGF‐R2‐related angiogenesis is linked with tumor progression. Methods ST3Gal1 and

Establishment of an innovative and sustainable PCR technique for 1534 locus mutation of the knockdown resistance (kdr) gene in the dengue vector Aedes albopictus

Parasites & Vectors, 2019
Background Mutation of the voltage-gated sodium channel (VGSC) gene, or knockdown resistance (kdr) gene, is an important resistance mechanism against DDT and pyrethroids for dengue vector Aedes albopictus.

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...
