| chemical constitute and larvicidal activity of fractions of ajuga chamaecistus tomentella plant against malaria vector anopheles stephensi. | the genus ajuga, belongs to lamiaceae family, is one of the exclusive subspecies in the flora of iran. the plants of this genus are used traditionally for treatment of joints pain, gout, jaundice, and as insecticide. | 2017 | 29026858 |
| biosurfactants produced by bacillus subtilis a1 and pseudomonas stutzeri na3 reduce longevity and fecundity of anopheles stephensi and show high toxicity against young instars. | anopheles stephensi acts as vector of plasmodium parasites, which are responsible for malaria in tropical and subtropical areas worldwide. currently, malaria management is a big challenge due to the presence of insecticide-resistant strains as well as to the development of plasmodium species highly resistant to major antimalarial drugs. therefore, the present study focused on biosurfactant produced by two bacteria bacillus subtilis a1 and pseudomonas stutzeri na3, evaluating them for insecticida ... | 2017 | 28936796 |
| managing wastes as green resources: cigarette butt-synthesized pesticides are highly toxic to malaria vectors with little impact on predatory copepods. | the development of novel mosquito control tools is a key prerequisite to build effective and reliable integrated vector management strategies. here, we proposed a novel method using cigarette butts for the synthesis of ag nanostructures toxic to young instars of the malaria vector anopheles stephensi, chloroquine (cq)-resistant malaria parasites plasmodium falciparum and microbial pathogens. the non-target impact of these nanomaterials in the aquatic environment was evaluated testing them at sub ... | 2017 | 28913784 |
| semi-high-throughput detection of plasmodium falciparum and plasmodium vivax oocysts in mosquitoes using bead-beating followed by circumsporozoite elisa and quantitative pcr. | the malaria infection status of mosquitoes is commonly determined by microscopic detection of oocysts on the dissected mosquito midgut. this method is labour-intensive, does not allow processing of large numbers of mosquitoes and can be challenging in terms of objective classification of oocysts. here, a semi-high-throughput bead-beating elisa method is proposed for detection of the circumsporozoite protein (csp) followed by confirmation by quantitative pcr (qpcr). | 2017 | 28877707 |
| a potent series targeting the malarial cgmp-dependent protein kinase clears infection and blocks transmission. | to combat drug resistance, new chemical entities are urgently required for use in next generation anti-malarial combinations. we report here the results of a medicinal chemistry programme focused on an imidazopyridine series targeting the plasmodium falciparum cyclic gmp-dependent protein kinase (pfpkg). the most potent compound (ml10) has an ic50 of 160 pm in a pfpkg kinase assay and inhibits p. falciparum blood stage proliferation in vitro with an ec50 of 2.1 nm. oral dosing renders blood stag ... | 2017 | 28874661 |
| response to blood meal in the fat body of anopheles stephensi using quantitative proteomics: toward new vector control strategies against malaria. | malaria remains a grand challenge for disruptive innovation in global health therapeutics and diagnostics. anopheles stephensi is one of the major vectors of malaria in asia. vector and transmission control are key focus areas in the fight against malaria, a field of postgenomics research where proteomics can play a substantive role. moreover, to identify novel strategies to control the vector population, it is necessary to understand the vector life processes at a global and molecular scale. in ... | 2017 | 28873011 |
| functional characterization of malaria parasites deficient in the k+ channel kch2. | k+ channels are integral membrane proteins, which contribute to maintain vital parameters such as the cellular membrane potential and cell volume. malaria parasites encode two k+ channel homologues, kch1 and kch2, which are well-conserved among members of the plasmodium genus. in the rodent malaria parasite p. berghei, the functional significance of k+ channel homologue pbkch2 was studied using targeted gene knock-out. the knockout parasites were characterized in a mouse model in terms of growth ... | 2017 | 28864420 |
| 3d mosquito screens to create window double screen traps for mosquito control. | mosquitoes are vectors for many diseases such as malaria. insecticide-treated bed nets and indoor residual spraying of insecticides are the principal malaria vector control tools used to prevent malaria in the tropics. other interventions aim at reducing man-vector contact. for example, house screening provides additive or synergistic effects to other implemented measures. we used commercial screen materials made of polyester, polyethylene or polypropylene to design novel mosquito screens that p ... | 2017 | 28851461 |
| complete mitochondrial genomes of anopheles stephensi and an. dirus and comparative evolutionary mitochondriomics of 50 mosquitoes. | to better understand the phylogeny and evolution of mosquitoes, the complete mitochondrial genome (mitogenome) of anopheles stephensi and an. dirus were sequenced and annotated, and a total of 50 mosquito mitogenomes were comparatively analyzed. the complete mitogenome of an. stephensi and an. dirus is 1,5371 bp and 1,5406 bp long, respectively. the main features of the 50 mosquito mitogenomes are conservative: 13 protein-coding genes (pcgs), two ribosomal rna genes, 22 transfer rna genes, posit ... | 2017 | 28794438 |
| acaricidal, pediculicidal and larvicidal activity of synthesized zno nanoparticles using momordica charantia leaf extract against blood feeding parasites. | the aim of the present study was to evaluate the acaricidal, pediculicidal and larvicidal effect of synthesized zinc oxide nanoparticles (zno nps) using momordica charantia leaf extract against the larvae of rhipicephalus (boophilus) microplus, adult of pediculus humanus capitis, and the larvae of anopheles stephensi, culex quinquefasciatus. the zno nps were characterized by using uv, xrd, ftir and sem-edx. the sem image confirms that the synthesized nanoparticles were spherical in shape with a ... | 2017 | 28760358 |
| morphometric and morphological appraisal of the eggs of anopheles stephensi (diptera: culicidae) from india. | anopheles stephensi is one of the most important urban malaria vectors in india and contribute about 12% of total malaria cases. an. stephensi has three ecological variants; type, intermediate and mysorensis that can be differentiated on the basis of differences in number of ridges on egg float and on the basis of spiracular indices. because of its anthropophilic nature the 'type' form is an efficient malaria vector. in the present study, the egg surface morphometry and morphology of an. stephen ... | 2018 | 28748836 |
| the role of midgut symbiotic bacteria in resistance of anopheles stephensi (diptera: culicidae) to organophosphate insecticides. | in the current study, the effects of the presence of symbiotic bacteria on the activity of the enzymes involved in an. stephensi resistance to temephos are evaluated for the first time. four different strains (i. susceptible strain, ii. resistant strain, iii. resistant strain + antibiotic, and iv. resistant strain + bacteria) were considered in order to determine the possible effects of the symbiotic bacteria on their hosts' resistance to temephos. the median values of all enzymes of susceptible ... | 2017 | 28745553 |
| mosquito-borne diseases and omics: tissue-restricted expression and alternative splicing revealed by transcriptome profiling of anopheles stephensi. | malaria is one of the most debilitating mosquito-borne diseases with high global health burdens. while much of the research on malaria and mosquito-borne diseases is focused on africa, southeast asia accounts for a sizable portion of the global burden of malaria. moreover, about 50% of the asian malaria incidence and deaths have been from india. a promising development in this context is that the completion of genome sequence of anopheles stephensi, a major malaria vector in asia, offers new opp ... | 2017 | 28708456 |
| nanos-driven expression of piggybac transposase induces mobilization of a synthetic autonomous transposon in the malaria vector mosquito, anopheles stephensi. | transposons are a class of selfish dna elements that can mobilize within a genome. if mobilization is accompanied by an increase in copy number (replicative transposition), the transposon may sweep through a population until it is fixed in all of its interbreeding members. this introgression has been proposed as the basis for drive systems to move genes with desirable phenotypes into target species. one such application would be to use them to move a gene conferring resistance to malaria parasit ... | 2017 | 28676355 |
