Background: Ovarian cancer survival in low- and middle-income countries is lower than in high-income countries, due to disparities in healthcare access and socioeconomic factors. This study aimed to describe trends in ovarian cancer survival in Sergipe, Northeast Brazil, by histological group.

Methods: We analysed data on 948 women aged 15-99 years diagnosed with a cancer of the ovary between 1996 and 2017, in Sergipe, Brazil.

Is the Real Two-Higgs-Doublet Model Consistent?

We provide strong evidence that the widely studied real two-Higgs-doublet model is inconsistent under renormalization due to quark-induced divergent CP violation (CPV). We identify the necessary ingredients for the CPV to enter the renormalization-group equations based on symmetry proprieties of the divergent diagrams. We demonstrate that while these ingredients are present starting at six loops, the divergent CPV is zero at that order due to approximate symmetries.

Serotonergic Modulation of the Excitation/Inhibition Balance in the Visual Cortex.

Serotonergic neurons constitute one of the main systems of neuromodulators, whose diffuse projections regulate the functions of the cerebral cortex. Serotonin (5-HT) is known to play a crucial role in the differential modulation of cortical activity related to behavioral contexts. Some features of the 5-HT signaling organization suggest its possible participation as a modulator of activity-dependent synaptic changes during the critical period of the primary visual cortex (V1).

TREK-1 inhibition promotes synaptic plasticity in the prelimbic cortex.

Synaptic plasticity is one of the putative mechanisms involved in the maturation of the prefrontal cortex (PFC) during postnatal development. Early life stress (ELS) affects the shaping of cortical circuitries through impairment of synaptic plasticity supporting the onset of mood disorders. Growing evidence suggests that dysfunctional postnatal maturation of the prelimbic division (PL) of the PFC might be related to the emergence of depression.
