Euschistus heros (Fabricius, 1798) (Heteroptera: Pentatomidae) is a soybean pest in Brazil. It has a reproductive success that may be associated with the female receptaculum seminis or spermatheca, a reproductive organ for spermatozoa storage until the oocyte fertilization. This study describes the anatomy and histology of the female receptaculum seminis in E.

Objective: To evaluate pFA and inflammatory profile in AAS users.
Mutations in the small genome present in mitochondria often result in severe pathologies. Different genetic strategies have been explored, aiming to rescue such mutations. A number of these strategies were based on the capacity of human mitochondria to import RNAs from the cytosol and designed to repress the replication of the mutated genomes or to provide the organelles with wild-type versions of mutant transcripts.

- Patients hospitalized with COVID-19 often have cardiovascular issues and high mortality rates, reaching 41.7% in a studied cohort of 2546 patients in Brazil.
- Factors significantly linked to high in-hospital mortality include the need for mechanical ventilation, elevated C-reactive protein, presence of cancer, and high troponin levels, with a notable interaction between age and sex observed.
- The study emphasizes the importance of understanding these risk factors for better patient monitoring and potential interventions based on unique characteristics related to age and sex.
Patients with COVID-19 who experience a myocardial infarction have complex coronary morphology and high in-hospital mortality: Primary results of a nationwide angiographic study.
Catheter Cardiovasc Interv
September 2021
Objectives: We aimed to explore angiographic patterns and in-hospital outcomes of patients with concomitant coronavirus disease-19 (COVID-19) and myocardial infarction (MI).
Background: Patients with COVID-19 may experience MI during the course of the viral infection. However, this association is currently poorly understood.
