Abstract

Background & Objectives: Mosquitoes (Diptera: Culicidae) are medically considered as one of the most important species of insects in terms of disease transmission to human beings; hence, they can be vectors of remarkable diseases such as malaria, West Nile, dengue fever, yellow fever, and filariasis. This study aimed to determine the species diversity and larval habitat characteristics of mosquitoes (Diptera: Culicidae) in Golestan Province in 2016.
Materials & Methods: In this descriptive cross-sectional study, larval habitats of mosquitoes were investigated in 14 counties of Golestan Province. Samples were collected by a standard ladle used for entomology. The collected larvae in lactophenol solution were transferred to a medical entomology laboratory in Gonbad-e Qabus County, and then microscopic slides were prepared. Mosquitoes species were identified based on their morphologic attributes and authentic identification keys. Larval habitat characteristics were studied in terms of the habitat type (permanent or temporary), water conditions (clear or turbid, stagnant or running), vegetation (with or without vegetation), sunlight exposure (full or partial exposure), and others. Data was analyzed using IBM SPSS software version 18.
Results: On the basis of analysis, 2891 third and fourth instars larvae, 4 genera (Anopheles, Culex, Culiseta, and Ochlerotatus), and 9 species (Anopheles superpictus, Culex mimiticus, Culex perexiguus, Culex pipiens, Culex pusillus, Culex theileri, Culex tritaeniohynchus, Culiseta longiareolata, Ochlerotatus caspius) of mosquitoes were detected, with the Culex pipiens being recognized as the dominant species of this family in Golestan Province.
Conclusion: Due to the high species diversity of Culicidae in Golestan Province, further studies are of essence to investigate the ecology of medically important species such as Culex pipiens, Culex tritaeniorhynchus, and Anopheles superpicts, which are the vectors of many diseases in Golestan province.

Abstract

Background and Objective: The application of exercise training and herbal supplements is believed to be a typical approach in treating chronic diseases and metabolic disorders. Accordingly, given the healing effects of swimming training and cannabidiol (CBD) oil consumption, the aim of the current study was to reveal if eight weeks of swimming training and CBD oil consumption downregulates the expression of MAPK, PPARα genes in the heart tissue of myocardial infarction rats.
Material and Methods: In the present experimental study, 20 myocardial infarction rats were divided into four groups of five animals, including: 1) control, 2 swimming training, 3) CBD, 4) CBD + swimming training, and 5) healthy control. For eight weeks, groups 3 and 4 consumed 50 mg/kg of CBD daily by gavage, and groups 2 and 4 performed swimming training five days a week. Induction of myocardial ischemia was performed by subcutaneous injection of isoproterenol (50 mg/kg i.p.), in myocardial infarction rats. Bax and Bcl2 cardiomyocytes were measured by PCR-RT. For data analysis, one-way analysis variance test was used to compare inter-group differences at P<0.05.
Results: Swimming training, CBD consumption and swimming training with CBD consumption had a significant effect on reducing MAPK gene expression in cardiac tissue (P≤0.05). Also, swimming training with CBD consumption had a greater effect than swimming training and CBD consumption alone on reducing PPARα gene expression in cardiac tissue (P≤0.05).
Conclusion: It appears that application of swimming training with CBD oil consumption has more positive impacts on improving MAPK and PPARα gene expression levels in the heart tissue of rats with myocardial infarction than using each one alone. Besides, swimming training with CBD oil consumption plays a role in the rehabilitation process and improves key factors involved in cardiovascular health.
