Potassium Persulfate Promoted the One-Pot and Selective -Functionalization of Pyrazoles under Acidic Conditions.

Our research presents selective direct selenylation at the C-4 pyrazole ring using KSO as an oxidant under simple and mild conditions. This elegant synthesis involves the one-pot method under acidic conditions, thus minimizing reaction steps and waste generation. This innovative method allowed us to create a library of 4-selanylpyrazoles in good to excellent yields.

Vaccination coverage according to race or skin color in children born in 2017-2018 in Natal, Rio Grande do Norte, Brazil: a population survey.

Objective: To analyze vaccination coverage up to 24 months of age according to race/ skin color in the 2017-2018 live birth cohort in Natal, Rio Grande do Norte, Brazil.

Methods: Population-based survey conducted in 2020 and 2021. Vaccination coverage up to 24 months of age was estimated according to administered, valid and timely doses.

Full vaccination coverage with valid doses among the 2017 and 2018 live birth cohort in the Southeast region of Brazil.

Objective: To analyze factors associated with full vaccination coverage with valid doses, in children from four state capitals and three other cities in Southeast Brazil.

Method: Analysis of a population survey conducted in 2020-2021, with a sample stratified according to socioeconomic levels of children born in 2017-2018, with data collected through photographic records of their vaccination cards. Odds ratios (OR) and 95% confidence intervals (95%CI) for full vaccination coverage were estimated based on the characteristics of the family, mother and child.

Measles, mumps and rubella vaccination coverage in capitals and interior region municipalities of Northeast Brazil: a household survey in a cohort of children born in 2017 and 2018.

Objective: To analyze measles, mumps, and rubella vaccination coverage among children up to 24 months old and factors associated with non-vaccination in a 2017-2018 live birth cohort, in state capitals and large interior region cities in Northeast Brazil.

Methods: Population-based survey analyzing vaccination coverage and sociodemographic factors through logistic regression.

Results: For 12,137 children, vaccination coverage was 79.

Thermal modulation of insecticide-induced hormetic and oxidative responses in insect pests.

Environmental global changes are dramatically affecting agroecosystems. Insects have been shown to present various responses to multi-stress conditions (i.e.
