In 1998, one of the largest determinations of organochlorine pesticides in a representative sample of a Spanish population (682 serum samples from the Canary Islands) was made in the context of the "Canary Islands Nutrition Survey" (ENCA). In the Canary Islands, extensive farming areas have been developed in these last decades, with greenhouses dedicated to intensive cultivation using DDT in hu...

The epsilon class glutathione-S-transferase of Anopheles gambiae, agGSTe2, is capable of metabolizing DDT. A molecular docking analysis of DDT with agGSTe2 support an E2 elimination mechanism wherein the glutathione sulfur serves as the base to convert DDT to DDE.

Although the advantages of Information Communication Technology (ICT), there is a dark side to its overuse, addiction technology causes physical and psychological human risks. This research aims understand phenomena Digital Detox Tourism (DDT); explore usage amongst digital natives immigrants; delve into tourists’ awareness impacts ICT’s excessive usage; investigate attitudes towards DDT, ident...

Indoor residual spraying (IRS) is used to control visceral leishmaniasis (VL) in India, but it is poorly quality assured. Quality assurance was performed in eight VL endemic districts in Bihar State, India, in 2014. Residual dichlorodiphenyltrichloroethane (DDT) was sampled from walls using Bostik tape discs, and DDT concentrations [grams of active ingredient per square meter (g ai/m(2))] were ...

and economic costs on many poor countries. For South Africa, which has a relatively minor malaria problem for a developing country, from 2000 to 2002 the economic cost ranged between US$15 million and US$41 million, excluding estimates of the human suffering and estimates of lost investment in malarial areas. The methods of controlling and treating the disease are well known and include indoor ...

Repeated annual episodes of Nile crocodile deaths in two isolated areas of the Kruger National Park prompted the investigation of possible organohalogen pollutant involvement. Crocodile eggs were collected close to one of the mortality sites (Gorge) as well as from a crocodile farm (CF) as reference. ∑DDT was significantly higher in Gorge (450ng/g wm) than in CF eggs (85ng/g wet mass). Percenta...

DNA damage tolerance (DDT) enables bypassing of DNA lesions during replication, thereby preventing fork stalling, replication stress, and secondary DNA damage related to fork stalling. Three modes of DDT have been documented: translesion synthesis (TLS), template switching (TS), and repriming. TLS and TS depend on site-specific PCNA K164 monoubiquitination and polyubiquitination, respectively. ...

This article discusses the role of DDT in the re-emerging cases of malaria worldwide. It is noted that malaria is reappearing in urban areas and in countries that previously eradicated the disease, including the Amazon Basin, South and North Korea, Armenia, Azerbaijan, and Tajikistan. In addition, the frequency of imported malaria has also increased in industrial countries. Although many fact...
