We modeled gravity data to explore Mercury's internal structure and show the presence of crustal heterogeneities in density. We first evaluated the lithospheric flexure occurring in the spherical harmonic degree range 5-80, according to the flexural isostatic response curve. We thus estimated a mean elastic lithosphere thickness of about 30 [Formula: see text] 10 km and modeled the crust-mantle interface, which varies from 19 to 42 km depth, according to a flexural compensation model.

Genome-wide association with 561 tropical maize inbred lines from Embrapa and DTMA panels was undertaken for root morphology and P acquisition traits under low- and high-P concentrations, with 353,540 SNPs. P supply modified root morphology traits, biomass and P content in the global maize panel, but root length and root surface area changed differentially in Embrapa and DTMA panels.

The breeding of genetically modified plants with resistance is seen as an important control strategy. However, the identification of molecules with high toxicity to this insect remains a challenge.

- The study investigated the presence of antiphospholipid antibodies (aPL) in pregnant women hospitalized with SARS-CoV-2, focusing on its potential impact on pregnancy and thrombotic complications.
- Sixteen out of 151 women were found to have positive aPL, with a higher incidence of obstetric complications such as HELLP syndrome and preeclampsia associated with aPL positivity.
- Overall, the findings suggest that while aPL were present, their frequency in pregnant women with COVID-19 remained similar to that in the general obstetric population.
Objectives: To investigate the association between chorionicity, birth weight discordance and neonatal morbidity in uncomplicated twin pregnancies progressing to at least 36 weeks of gestation.
Study Design: This was a retrospective single centre cohort study of all twin pregnancies referred to our twin clinic between 2011 and 2018. Outcome details were obtained from the computerized maternity and neonatal records.
