Dr. Gilbert will present the research on the physiology of cardiovascular disease: Gender disparities conference, October 12 to 14 at the University of Mississippi in Jackson. The conference is sponsored by the American Physiological Society with additional support from the American Heart Association. His presentation is titled “Training exercise before and during pregnancy improves endothermic function and stimulates overprotective and antioxidant pathways in pregnant rats.”

VEGF

In the study, rats were divided into two groups, the exercise group and the control group, and impregnated later. The exercise group ran voluntarily on a wheel of activity for six weeks before and during pregnancy, with running times and distances up weekly. The control group did not exercise. The team analyzed tissue samples from both groups at the end of pregnancy.

The researchers found that rats in the exercise group had higher levels of a circulating protein called vascular endothermic growth factor (VEGF) than the control group. VEGF and pregnancy-specific version of a protein called placental growth factor (PlGF) are important because not only stimulate the development of new blood vessels, also to maintain the normal function of the vessels which in turn promotes good cardiovascular health.

According to Dr. Gilbert, the pursuit of VEGF increased in the exercise group has important implications for understanding, and perhaps the prevention of preeclampsia. He noted that clinical and experimental studies have shown that high levels of a protein called sFlt-1 can be attached to the mother’s levels of circulating VEGF and PlGF and may lead to preeclampsia.

The researchers also found that when VEGF increased, increased endothermic function. The endothermic is a thin layer of cells lining the inside of blood vessels. Turbulence is reduced blood flow, allowing more blood is pumped with each heartbeat, giving the strain on the heart.

Heat shock proteins

The team also found that rats in the exercise group had increased amounts of heat shock proteins (HSP) compared with those who did not exercise. A HSP, including HSP 90, are believed to play a vital role in maintaining the heart’s blood vessels. It works in sync with the VEGF and nitric oxide to dilate blood vessels so blood flows more freely, reducing blood pressure. Increased expression of HSPs, as a result of exercise can provide a preconditioning effect that can help protect against cell damage in the placenta during pregnancy complicated by high blood pressure.

“There have been many studies on exercise and pregnancy, but not at the molecular level,” said Gilbert. “We hope to know whether the stimulation of these proteins with the year before pregnancy or during early pregnancy can reduce a woman’s risk of preeclampsia.”

How do I save babies born prematurely

How do I save babies born prematurelyIn the extreme cases, they are babies that fit in the palm of a hand. In certain circumstances, these young are born very prematurely, and the only way to survive is to complete gestation in an artificial way, i.e. in an incubator simulating the conditions of the womb, as long as necessary.

Fortunately, unlike what happened a few years ago, today the recovery of premature babies is becoming higher. New criteria, such as
prioritize contact with their parents, as well as huge medical advances, have contributed to a marked improvement in the super wind rates of these infants worldwide.
For information on premature birth comes more and more sectors of the population in our country is being held from next Monday October 4, the first week of prematurely, organized by UNICEF Argentina, and of which more than 70 maternity in 45 cities in 17 provinces.

The occasion will be used to communicate about the rights they have mothers and premature babies, and each health center will organize different activities. Among them: talks, games, children’s shows, video conferencing, training sessions,
and more. The idea is to repeat the event every year.

ORGANIZING According to World Health Organization (WHO), the premature infant is one born before 37 weeks of pregnancy and one of the features found in low birth weight. According to the same source, is considered low birth weight below 2,500 g, very low birth weight to less than 1,500 g, and extremely low birth weight below 1,000 g.
These little ones are born when they are not ready to do so, since many of its vital functions like breathing, are not yet developed.

Unfortunately, the leading cause of infant mortality, i.e. during the first year of life, prematurely, and in this case, the key insight is the weight they are born. While virtually all infants less than 2500g survived, not so with the smaller, less than 1,500 or 1,000 g.
Given that early births are partly preventable, unique campaign aims to raise awareness of the major risk factors that trigger, and relevant to the lives and work of women, poverty, issues biological and psychological.

Why is physical activity essential for maintaining pregnancy

maintaining pregnancyThe human being is made to stay in motion while maintaining their health and vitality, so the physical activity will lead to a better quality of life. During the fertile period of all human beings, it is vital physical activity to regulate the hormonal system, thereby increasing the chances of pregnancy.

Pregnancy is a period of many changes in our body which women must adapt, the exercise provided by a physician licensed to help us address them in a better way.

Among the benefits it can bring physical activity during this period include:

* There is evidence that women engaged in physical activity during pregnancy and before that handled better weight gain without this affecting the development of the infant.
* Reduces back pain associated with pregnancy, this is achieved by correcting posture and strengthening the muscles of the lower back and abdominal organs containing staying in this area.
* The children of mothers, who exercise, have higher physical abilities.
* Increases self-esteem, through the secretion of hormones that help control moods.
* Improves blood flow through the placenta, thus improving nutrition to the fetus.
* Prepare the pelvic floor to support the increased weight and prevent urological and gynecological dysfunction, through strength training.
* Helps improve body awareness, postural alignment, muscle tone and recovery of flexibility, which promotes labor.
* Prepare the top of our body to demands of breastfeeding and newborn care.

It is these and many other benefits it provides the physical activity during pregnancy and throughout our lives, but it is vital that the exercise is conducted under the supervision of trained professionals in the field. The exercises should be based on relaxation, breathing, alignment, coordination, strength and fluidity of movement. Not for any reason must submit to the practice of unsupervised physical activity or high intensity where we increase the body temperature too much, since we can impair normal fetal development.
