Role of the Southern Annular Mode in the sea level over the southern Blue Amazon.

Regional sea level rise varies from the global average and is influenced by climate variability. We studied sea level anomalies in southern Brazil from 1993 to 2022, finding increasing trend from 1993 to 2022. We used oceanic and atmospheric dynamics to understand the rapid sea level rise.

Changes in atmospheric circulation and evapotranspiration are reducing rainfall in the Brazilian Cerrado.

Here we analyze the trends of rainfall and the frequency of rainy days over the Brazilian Cerrado between 1960 and 2021 in four distinct periods according to the seasonal patterns over the region. We also evaluated trends in evapotranspiration, atmospheric pressure, winds, and atmospheric humidity over the Cerrado to elucidate the possible reasons for the detected trends. We recorded a significant reduction in rainfall and frequency of rainy days in the northern and central Cerrado regions for all periods except at the beginning of the dry season.

[A simple and fast enzyme immunoassay for the quantitative determination of C-reactive protein].

The principle is based on the competitive binding of the enzyme-labelled CRP (enzyme: alkaline phosphatase) and the serum CRP to solid phase-bound antibodies. The detection limit was 10 micrograms/l. The precision in the series in the border-line "normal" to "pathological" (5 mg/l) was 2.
