In the Americas, areas with a high risk of malaria transmission are mainly located in
the Amazon Forest, which extends across nine countries. One keystone step to
understanding the Plasmodium life cycle in Anopheles species from the Amazon Region
is to obtain experimentally infected mosquito vectors. Several attempts to colonise
Ano- pheles species have been conducted, but with only short-lived success or no
success at all. In this review, we review the literature on malaria transmission from
the perspective of its Amazon vectors. Currently, it is possible to develop
experimental Plasmodium vivax infection of the colonised and field-captured vectors
in laboratories located close to Amazonian endemic areas. We are also reviewing
studies related to the immune response to P. vivax infection of Anopheles aquasalis,
a coastal mosquito species. Finally, we discuss the importance of the modulation of
Plasmodium infection by the vector microbiota and also consider the anopheline
genomes. The establishment of experimental mosquito infections with Plasmodium
falciparum, Plasmodium yoelii and Plasmodium berghei parasites that could provide
interesting models for studying malaria in the Amazonian scenario is important.
Understanding the molecular mechanisms involved in the development of the parasites
in New World vectors is crucial in order to better determine the interaction process
and vectorial competence. 相似文献

Structure based virtual screening of ligands to identify cysteinyl leukotriene receptor 1 antagonist

Montelukast and Zafirlukast are known leukotriene receptor antagonists prescribed in asthma treatment. However, these fall short
as mono therapy and are frequently used in combination with inhaled glucocorticosteroids with or without long acting beta 2
agonists. Therefore, it is of interest to apply ligand and structure based virtual screening strategies to identify compounds akin to
lead compounds Montelukast and Zafirlukast. Hence, compounds with structures having 95% similarity to these compounds were
retrieved from NCBI׳s PubChem database. Compounds similar to lead were grouped and docked at the antagonist binding site of
cysteinyl leukotriene receptor 1. This exercise identified compounds UNII 70RV86E50Q (Pub Cid 71587778) and Sure CN 9587085
(Pub Cid 19793614) with higher predicted binding compared to Montelukast and Zafirlukast. It is shown that the compound Sure
CN 9587085 showed appreciable ligand receptor interaction compared to UNII 70RV86E50Q. Thus, the compound Sure CN
9587085 is selected as a potent antagonist to cysteinyl leukotriene receptor 1 for further consideration in vitro and in vivo validation. 相似文献

Changes of the tyrosinase activity in ontogenesis of the house fly Musca domestica were shown to be phase-specific and ontogenetic changes of tyrosinase and dihydroxyphenylalanine oxidase activities proved to be coordinated. Ascorbic acid stimulated some ontogenetic stages of the house fly and physiological indices, such as fertility, survival at different stages, and weight of puparia. Also, ascorbic acid modulated the tyrosinase activity. 相似文献

Random amplified polymorphic DNA (RAPD) analysis was adapted for genomic identification of cell cultures and evaluation of DNA stability in cells of different origin at different culture passages. DNA stability was observed in cultures after no more than 5 passages. Adipose-derived stromal cells demonstrated increased DNA instability. RAPD fragments from different cell lines after different number of passages were cloned and sequenced. The chromosomal localization of these fragments was identified and single-nucleotide variations in RAPD fragments isolated from cell lines after 8–12 passages were revealed. Some of them had permanent localization, while most variations demonstrated random distribution and can be considered as de novo mutations. 相似文献

Background
The genus Morus, known as mulberry, is a dioecious and cross-pollinating plant that is the sole food for the domesticated silkworm, Bombyx mori. Traditional methods using morphological traits for classification are largely unsuccessful in establishing the diversity and relationships among different mulberry species because of environmental influence on traits of interest. As a more robust alternative, PCR based marker assays including RAPD and ISSR were employed to study the genetic diversity and interrelationships among twelve domesticated and three wild mulberry species. 相似文献9.

Presented in the work are data on interrace differences in mechanisms of formation of antioxidant and phenoloxidase complexes in honeybees of the Middle Russian (Apis mellifera L.) and Caucasian (Apis mellifera caucasica Gorb.) geographic races. Different degree has been revealed of activation of these complexes depending on their localization in the insect organism and providing different strategy of adaptation to temperature stress. A diverse role of ascorbic acid in regulation of the honeybee protective system has been shown. 相似文献
