Alzheimer's Disease Mortality Rate: Correlation with Socio-Economic and Environmental Factors.

The progressive increase in the number of deaths caused by Alzheimer's disease (AD) in Brazil and around the world between 2010 and 2020 raises questions in scientific society. At the same time, there is also an increase in life expectancy at birth (LEB). Thus, the aim of this study was, for the first time, to compare the increase in AD mortality rate (ADMR) in Brazilian regions over the years 2010 to 2020 with the increase in LEB, and investigate the possible correlation between these demographic transition phenomena and pesticide sales and exposure during this period.

Amblyomma auricularium (Acari: Ixodidae): underwater survival of the non-parasitic phase of feeding females.

To determine the effects of immersion in water on the biological parameters of engorged females of the tick species Amblyomma auricularium, 60 females were distributed in six groups, each comprising 10 individuals. The control group - G1 (not immersed) was fixed dorsally in a Petri dish and incubated at 27 ± 1°C and 80% RH. The other groups were subjected to immersion periods of 24, 48, 72 and 96 hours, and the sixth group to continuous immersion.
