The Least Toxic Ways to Protect Yourself from Ticks
When it comes to keeping away creatures that creep and crawl, the U.S. doesn’t mess around. More than 198 million Americans used insect repellent last year, a figure that is expected to top 200 million this year. Much of that is to ward off ticks, which are technically arachnids and carry more than a dozen diseases. But the repellents themselves can present concerns of their own with their pungent smells, occasional irritation, and labels full of mystifying chemicals most people have never heard of. [time-brightcove not-tgx=”true”] With 2023 turning into one of the worst tick seasons in recent memory, pl...

Fruit Flies Are Spreading Across U.S. Crops. The Government ’s Outdated Approach Isn’t Helping
For two weeks in August, a crew of workers systematically confiscated every orange in Vince Bernard’s groves in Valley Center, Calif. They buried the oranges—at least $500,000 worth of fruit, Bernard says—in ditches on his neighbor’s property. They did so by order of the U.S. government, which came accompanied by armed California Highway Patrol officers and which did not pay Bernard a penny for the crops. Bernard’s oranges were destroyed because the California Department of Food and Agriculture (CDFA) found five Mexican fruit flies on a neighbor’s property, which it considers “an i...

Therapeutic Potential of Bee and Scorpion Venom Phospholipase A2 (PLA2): A Narrative Review
Iran J Med Sci. 2022 Jul;47(4):300-313. doi: 10.30476/IJMS.2021.88511.1927.ABSTRACTVenomous arthropods such as scorpions and bees form one of the important groups with an essential role in medical entomology. Their venom possesses a mixture of diverse compounds, such as peptides, some of which have toxic effects, and enzymatic peptide Phospholipase A2 (PLA2) with a pharmacological potential in the treatment of a wide range of diseases. Bee and scorpion venom PLA2 group III has been used in immunotherapy, the treatment of neurodegenerative and inflammatory diseases. They were assessed for antinociceptive, wound healing, ant...

Docosahexaenoic Acid Increases the Potency of Soluble Epoxide Hydrolase Inhibitor in Alleviating Streptozotocin-Induced Alzheimer ’s Disease-Like Complications of Diabetes
Conclusion In the present study, we demonstrated that sEHI alleviates cognitive and memory impairment associated with diabetes-induced Alzheimer-like complication. The positive effect of sEHI TPPU on memory was associated with a reduction in oxidative stress and inflammation in the brain with a parallel decrease in the mRNA level of APP and activity of AChE. The DHA potentiated the effect of TPPU. Edaravone at a higher dose also alleviated memory impairment via decreasing oxidative stress and inflammation. Author Contributions RP, MA, SA, ML, and SG planned the experiments. RP, NB, KG, MA, and SA performed the experimen...

DEET Is the Most Effective Bug Spray. But Is It Safe?
Sure, itchy bug bites are a nuisance. But for those living in parts of the country where mosquito or tick-borne illnesses are common—and these days, that’s most of us—bug-repellent sprays and liquids are an important safeguard against Lyme disease, West Nile virus and other serious health conditions. The annual number of people sickened by mosquitos or tick bites has more than tripled since 2004, according to the CDC. The World Health Organization has concluded that climate change is a likely contributor to these increases, which are predicted to continue as warmer global temperatures expand the habitats ...

Active Compounds Against Anopheles minimus Carboxypeptidase B for Malaria Transmission-Blocking Strategy
Malaria transmission-blocking compounds have been studied to block the transmission of malaria parasites, especially the drug-resistant Plasmodium. Carboxypeptidase B (CPB) in the midgut of Anopheline mosquitoes has been demonstrated to be essential for the sexual development of Plasmodium in the mosquito. Thus, the CPB is a potential target for blocking compounds. The aim of this research was to screen compounds from the National Cancer Institute (NCI) diversity dataset and U.S. Food and Drug Administration (FDA)-approved drugs that could reduce the Anopheles CPB activity. The cDNA fragment of cpb gene from An. minimus (c...
