Endocrine disruptors-phytoestrogens

 

 Phytoestrogen is one kind of  endocrine disruptor that is commonly found in cereals, berries, and mung beans. It acts like estrogen in human body. In some medicines, phytoestrogens are sometimes used to protect against hormone-dependent cancers. It can also reduce the risk of osteoporosis, heart disease, breast cancer, and menopausal symptoms. On the down side however, phytoestrogen could harm the reproductive health of males by acting as antiestrogens. Men excrete more enterolactone and less enterodiol than women when they ingest to much phytoestrogen. Phytoestrogen can also affect fertility of domestic animals. For example, if phytoestrogen in in hot, dry summer day, it can reduce the number of offsprings in wild population of quail.

CPR Blog

    CPR is a chest compression and rescue breathing procedure. If someone is not circulating blood or breathing adequately, CPR will help to restore circulation of oxygen rich blood. Without oxygen, a brain can die within 8 minutes. One should perforn CPR for about 2 minutes before calling for help.CPR may be necessary for drowning, suffocation, poisoning, smoke inhalation, electrocution injuries, etc.
     In babies or children, rubbing over the breastbone can help determine if there is any level of responsiveness. Meanwhile for older childrem or adults, the same process could be done by gently tapping the shoulders.
     Before doing any of the process, one must determine if it is safe to approach the person. For example, if one person is electrocuted, make sure all electric currents are turned off to prevent further electrocution.
   When approaching that person, make sure to evalutate whether the person is responsive. Look for sounds of mouth, eye opening, chest movement, and pulse. CPR is continued until of spontaneous circulation(ROSC) or is declared dead.
