Mechanism of Cisplatin Anti-Cancer Drug
Mechanism of Cisplatin Anti-Cancer Drug Scott Stevens 16,988 Views • 3 years ago

Cisplatin is in a class of drugs known as platinum-containing compounds used to treat various types of cancers including metastatic testicular and ovarian tumors. The molecule was first discovered in 1845, but did not receive FDA approval until 1978. Today it is known as the "penicillin of cancer drugs," because it is so effective for many different cancers. There are three key players involved in Cisplatin's mechanism: (1) Cisplatin, (2) DNA (3) and an HMG Protein. Most Cisplatin enters the body through active transport, but some molecules are passively defused through the cell membrane. Once in the nucleus, Cisplatin can form an adduct with two consecutive guanine bases within a strand of DNA. The molecule loses its chlorine atoms in exchange for the nitrogen atoms of the target guanines. Cisplatin can bond more tightly with nitrogen because nitrogen balances the platinum charge more effectively than chlorine. It is this adduct-induced DNA bend that allows binding of proteins which contain the high mobility group, HMG domain. Once the protein is bound to the DNA, it inserts a wedge-like phenyl group of phenylalanine 37 into the widened minor groove created by the bend. The tightly bound HMG protein causes destacking of the nucleotide bases, resulting in the DNA helix becoming kinked. In this way, Cisplatin can be thought of as a monkey wrench in the DNA repair system. With the HMG protein bound to the DNA, the modified strand is not repaired properly and so the cell dies. The success of Cisplatin depends on its ratio of efficacy between cancerous and healthy cells.

Mechanism of a Breech CHildbirth Delivery
Mechanism of a Breech CHildbirth Delivery Scott 14,495 Views • 3 years ago

The majority of fetuses are in a breech presentation early in pregnancy. By week 38th week of gestation, however, the fetus normally turns to a cephalic presentation. Although the fetal head is the widest single diameter, the fetus’s buttocks [ breech], plus the lower extremities, actually takes up more space. The fundus, being the largest part of the uterus, probably accounts for the fact that in approximately 97% of all pregnancies, the fetus turns so that the buttocks and lower extremities are in the fundus. Vaginal delivery of a breech presentation requires great skill if the fetus is not to be damaged. With the low rate of vaginal breech deliveries in the developed world, experience is being lost. 6% of women with breech presentation still have a vaginal breech delivery as they present too late - so units need to retain a high level of preparedness. Types of breech presentation: I. Complete breech [ flexed breech]: The fetal attitude is one of complete flexion, with hips and knees both flexed and the feet tucked in beside the buttocks. The presenting part consists of two buttocks, external genitalia and two feet. It is commonly present in multiparae. II. Incomplete breech: This is due to varying degrees of extension of thighs or legs at podalic pole. Three varieties are possible; - Breech with extended legs [ frank breech ]: The breech presents with the hips flexed and legs extended on the abdomen. 70% of breech presentations are of this type and it is particularly common in primigravidae whose good uterine muscle tone inhibits flexion of the legs and free turning of the fetus. - Footling breech: This is rare. One or both feet present because neither hips nor knees are fully flexed. The feet are lower than the buttocks, which distinguishes it from the complete breech. - Knee presentation: This is very rare. Thighs are extended but the knees are flexed, bringing the knees down to present at the brim.

Thyroiditis is a general term that refers to “inflammation of the thyroid gland”. Thyroiditis includes a group of individual disorders causing thyroidal inflammation but presenting in different ways. For example, Hashimoto’s thyroiditis is the most common cause of hypothyroidism in the United States. Postpartum thyroiditis, which causes temporary thyrotoxicosis (high thyroid hormone levels in the blood) followed by temporary hypothyroidism, is a common cause of thyroid problems after the delivery of a baby. Subacute thyroiditis is the major cause of pain in the thyroid. Thyroiditis can also be seen in patients taking the drugs interferon and amiodarone.

Urinary Tract Infection Treatment
Urinary Tract Infection Treatment samer kareem 2,908 Views • 3 years ago

Urinary tract infections (UTIs) are infections of the urethra, bladder, ureters, or the kidneys, which comprise the urinary tract. E. coli bacteria cause the majority of UTIs, but many other bacteria, fungi, and parasites may also cause UTIs. Females have a higher risk for UTIs than most males, probably because of their anatomy; other risk factors for UTIs include any condition that may impede urine flow (e.g., enlarged prostate, kidney stones, congenital urinary tract abnormalities, and inflammation). Patients with catheters or those who undergo urinary surgery and men with enlarged prostates are at higher risk for UTIs.
