2. Coverage plants in the management of skeletal coffee
ABSTRACT Currently, one of the most used practices in national coffee production is skeletal pruning, to preserve productive capacity, correct plant architecture, minimize the occurrence of diseases, among others. Also, it reduces the plants diameter, exposing the soil to climatic conditions, erosion, loss of moisture and nutrients, negatively affecting the

3. Macrophages: key players in erythrocyte turnover
ABSTRACT The development of red blood cells (RBCs), or erythropoiesis, occurs in specialized niches in the bone marrow, called erythroblastic islands, composed of a central macrophage surrounded by erythroblasts at different stages of differentiation. Upon anemia or hypoxemia, erythropoiesis extends to extramedullary sites, mainly spleen and liver, a process

8. Revisiting the History of Chagas Disease: "Live to tell"
Abstract In 1907, Carlos Chagas was designated to fight paludism in the Rio das Velhas region along the Central do Brasil railroad. During his field research, Chagas discovered a hematophagous insect ( Panstrongylus megitus ) carrying a new trypanosomatide, which he named Trypanosoma cruzi . On April 14th, 1909, he found the same parasite in the blood of a f

9. Orchio-Septopexy: A new technique to cover and fix detorsed testis undergoing fasciotomy of tunica albuginea
ABSTRACT Purpose Compartment Syndrome (CS) has been recognized as a potential factor that worsens testicular viability after detorsion, especially in borderline cases of prolonged ischemia. Fasciotomy of the testicular tunica albuginea to relieve the pressure associated with CS has been proposed to accommodate edema after detorsion, embracing the raw fasci

10. A new option to prevent fistulas in anterior urethroplasty in patients with kippered urethra: the tunica vaginalis flap
ABSTRACT The objective of this study is describing a technique with the use of a tunica vaginalis flap (TVF) to cover the suture line during anterior urethroplasty in patients with kippered urethra due to chronic indwelling catheterization (CIC). We studied 5 patients (mean age=50.2) with a neurogenic bladder that developed urethral erosion after a long peri

12. Performance of cover crops under two irrigation regimes in the Coastal Tablelands region of Brazil
ABSTRACT There is currently a lack of information regarding the performance of cover crops grown in the Coastal Tablelands region in the North of the Brazilian state of Espírito Santo, where zero tillage is increasingly being adopted. The objective of this study was to evaluate the agronomic performance of six cover crops (ruzi grass, jack bean, and the mil
