It is a nitrogen mustard alkylating agent. Ifosfamide is a cyclophosphamide analogue thus it has all the potential adverse effects of cyclophosphamide. Ifosfamide metabolite, rather than the parent drug is responsible for toxicity of Ifosfamide. Ifosfamide is a prodrug that requires metabolic activation by microsomal liver enzymes to produce biologically active compounds. Activation is mediated by cytochrome p450 - CYP3A4 and deactivated by CYP3A-4 AND CYP2B6. The metabolic activation of Ifosfamide is an autoinducible process and besides producing active cytotoxic metabolites it also results in generation of some toxic metabolic byproducts that are responsible for its side effects. The two well known toxic nzetabolities of Ifosfamide are acrolein and chloracetaldehyde. - \"Acrolein is responsible for Ifosfamide induced hemorrhagic cystitis where as chloroacetaldehyde is responsible for renal tubular damage and neutrotoxicity\". Acrolein - Hemorrhagic cystitis Chloroacetaldehyde - Nephrotoxicity (Renal tubular danage) - Neurotoxicity At equivalent doses, the rate of chloroacetaldehyde generation with ifosfamide is 40 times greater than with cyclophosphamide. -This explains why cyclophosphamide although structurally related has viually no nephrotoxicity and less neurotoxic. Goodman Gilman Says - At equivalent doses, the rate of chloroacetaldehyde generation with ifosfamide is 40 times greater than with cyclophosphamide therefore it produces more platelet suppression, neurotoxicity, urothelial damage. Neurotoxicity in ifosfamide Neurotoxity in ifosfamide is caused by the active metabolite of ifosfamide i.e., chloralacetaldehyde These metabolites enter brain and produce neurological symptoms which are encephalopathy and seizure. These symptoms almost always resolve with discontinuation of the drug. Patients who have mild to moderate symptoms can continue to receive the drug." } ]

That is why patients with no physical signs and symptoms (like tender lymph nodes, sore throat) but with history of long-standing fatigue should be carefully screened for presence of atypical depression.Other importent feature of ATYPICAL DEPRESSION are (compared to the patients with non-atypical depression)1.

Molecular cloning and expression of alfalfa isoflavone reductase, a key enzyme of isoflavonoid phytoalexin biosynthesis. The major phytoalexin in alfalfa is the isoflavonoid (-)-medicarpin (or 6aR, 11aR)-medicarpin. Isoflavone reductase (IFR), the penultimate enzyme in medicarpin biosynthesis, is responsible for introducing one of two chiral centers in (-)-medicarpin. We have isolated a 1.18 kb alfalfa cDNA (pIFRalf1) which, when expressed in Escherichia coli, converts 2'-hydroxyformononetin stereospecifically to (3R)-vestitone, as would be predicted for IFR from alfalfa. The calculated molecular weight of the polypeptide (35,400) derived from the 954 bp open reading frame compares favorably to estimated Mrs determined for IFR proteins purified from other legumes. The transcript (1.4 kb) is highly induced in elicited alfalfa cell cultures. The kinetics of induction are consistent with the appearance of IFR activity, the accumulation of medicarpin, and the observed induction of other enzymes in the pathway. Low levels of IFR transcripts were found in healthy plant parts (roots and nodules) which accumulate low levels of a medicarpin glucoside. IFR appears to be encoded by a single gene in alfalfa. The cloning of IFR opens up the possibility of genetic manipulation of phytoalexin biosynthesis in alfalfa by altering isoflavonoid stereochemistry." }, { "from": "gpt", "value": "Answer: [Answer placeholder]" } ]

The extent of thrombus in each limb was quantitated at each interval by VDUS of the residual thrombus present in each of five major axial venous segments: the common femoral, superficial femoral, profunda femoris, popliteal, and tibial veins. Thrombus scores for the group at each interval were compared with baseline scores at diagnosis to calculate the percent residual thrombus. Endogenous fibrinolytic activity was determined at the same intervals by serologic assay of the biologic activities of tPA and its inhibitor PAI-1.', 'Thrombus regression was evident by VDUS at 1 to 2 weeks and progressed such that only 26% of residual thrombus remained at 24 to 36 weeks.
