Because malaria is caused by Plasmodium parasites brought on by bites of infected mosquitos, countries should use vector control. Two forms of vector control are insecticide-treated nets and indoor residual spraying. Both are effective in a wide range of circumstances.

Bodybuilders that take anabolic steroids such as androstenedione and testosterone often suffer from gynecomasty (enlarged breast
Whitepunk [10]

Answer:

Gynaecomastia occurs due to

1) Feedback inhibition of pituitary.

2) Conversion of exogenous androgens into estrogen (aromatization)

Substrate : Androgen

Product : Estradiol ( estrogen )

Enzyme involved : Aromatase

Explanation:

Gynaecomastia is a condition in which the mammary

glands, or breasts, enlarge and become sore and

tender to touch. It is due to the chemical change

in testosterone brought about by a process called

aromatisation, when the male hormone is converted

to a form of estrogen, the female sex hormone.

There is initially a sore feeling in the breast. A

skin ridge appears on the outer side of the areola

together with a halo appearance around the area

but no swelling. As the course continues, a swelling

develops and it becomes tender. Fatty tissue

builds up around the area and the breast becomes

prominent. At times there may be a secretion of

fluid from the nipple when it is squeezed. Steroids

should be stopped. If recovery does not occur by

the end of 2 months, surgery should be considered.

Other causes of gynaecomastia that may need to

be considered are the use of medications such as

Tagamet, a treatment for gastric problems, HCG and

spironolactone. Some body builders use this latter

drug to reduce body fluid. Occasionally boys in the

post-pubertal phase develop breast enlargement due

to endocrine imbalance totally unrelated to steroids.

Gynaecomastia also occurs as a result of feedback inhibition of the pituitary.

Andreas93 [3]

Pregnancy has no effect on blood flow. receiving a blood transfusion increases blood flow greatly.

<h3>What is blood transfusion?</h3>

Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components.

Patients who have sustained major injuries in vehicle accidents or natural disasters are treated with blood transfusions. Blood transfusions are frequently given to people who have a condition like leukemia or kidney disease, both of which can induce anemia.

Through a little tube inserted into a vein in your arm, donated blood is given to you as part of a standard medical operation known as a blood transfusion. Blood lost during surgery or an accident can be replaced with the aid of this potentially life-saving technique.

Zinaida [17]
