Corn Stunt is an important disease in the Americas due to it high prevalence and the yield reductions that can cause when present. However, changes in the presence of this disease across years hampers the effective identification of resistant genotypes to this disease. To avoid the limitations of phenotypic selection under natural pressure, this research aimed to devise an effective strategy to screen disease-resistant genotypes in the absence of high and constant natural pressures.

Gestational diabetes mellitus (GDM) is a complex condition that involves a variety of pathological mechanisms, including pancreatic β-cell failure, insulin resistance, and inflammation. There is an increasing body of literature suggesting that these interrelated phenomena may arise from the common mechanism of endoplasmic reticulum (ER) stress. Both obesity-associated nutrient excess and hyperglycemia disturb ER function in protein folding and transport.

Prenatal development is currently recognized as a critical period in the etiology of human diseases. This is particularly so when an unfavorable environment interacts with a genetic predisposition. The fetal programming concept suggests that maternal nutritional imbalance and metabolic disturbances may have a persistent and intergenerational effect on the health of offspring and on the risk of diseases such as obesity, diabetes, and cardiovascular diseases.

Pre-eclampsia appears to be the main cause for the maternal and fetal morbidity and mortality. Pregnant women with pre-eclampsia are more likely to be threatened with conditions which potentially may be lethal, such as: disseminated intravascular coagulation, cerebral hemorrhage, liver and renal failure. Pregnancy complicated with pre-eclampsia is also associated with a greater risk for iatrogenic prematurity, intrauterine growth retardation, premature abruption of placenta, and even intrauterine fetal death.

Article Synopsis
  • Observational studies suggest that low omega-3 fatty acid levels may increase the risk of pregnancy disorders like preeclampsia and IUGR due to excessive cell death (apoptosis).
  • A study investigated the effects of fish oil supplementation (300 mg DHA) in 28 pregnant women, comparing them to a control group of 50 women without supplementation.
  • Results showed that DHA supplementation significantly reduced markers of apoptosis (caspase 3 activity) in the DHA group, but did not affect proliferation markers (p21 and Ki-67) in the placenta.

There are suggestions in the literature that pre-eclampsia has an immunological basis, in which there is a failure of the immune system to recognize fetal alloantigens. It seems that abnormal activation of the inflammatory response may play a role in the etiopathogenesis of pre-eclampsia. Many authors have found a number of changes in the immune system which might have contributed to its development.

Pregnancy is a specific state of heightened coagulability related to the increase in procoagulant agents and to the reduced fibrinolysis. Pregnancy is associated with a 4-fold increased risk of developing venous thromboembolism (VTE) and this risk still increases to 14-fold during puerperium. A correlation between the metabolic syndrome and development of cardiovascular events and cerebrovascular incidents has been described.

Article Synopsis
  • The recognition and treatment of hyperglycemia during pregnancy are crucial to prevent complications in newborns related to gestational diabetes mellitus (GDM).
  • While traditional treatment often involves insulin, which has drawbacks, there is interest in finding effective alternatives like glyburide.
  • Although the FDA classifies glyburide as Category C and does not officially approve it for GDM, ACOG suggests it may be as effective as insulin; however, more research is needed to clarify its safety and efficacy during pregnancy.
