چکیده

Keberhasilan budidaya tanaman karet dipengaruhi oleh beberapa faktor, salah satunya manajemen penyakit tanaman. Penyakit gugur daun merupakan satu penting karena dapat menurunkan produksi lateks. pada di lapangan cukup sulit diatasi. Pengendalian yang dianggap lebih efisien adalah dengan pencegahan melalui penggunaan klon memiliki sifat ketahanan tinggi terhadap patogen. Hal ini mendorong para pemulia untuk terus melakukan seleksi dan menghasilkan unggul baru berproduksi juga tahan daun. Penelitian dilakukan menseleksi sekunder progeni F1 hasil persilangan PB 260 x RRIC 100 tahapan seedling evaluation trials (SET). Pengamatan 290 tahun tanam 2012 2014 kebun (SET) Pusat Karet Sembawa, Sumatra Selatan. keparahan empat jenis yaitu Pestalotiopsis, Corynespora, Colletotrichum, Oidium. secara visual melihat persentase berdasarkan gejala luasan kanopi terserang, serta akibat tersebut. Evaluasi menunjukkan variasi setiap Sebanyak 62 tingkat karet.

A correlation between cytotoxicity and reductase-mediated metabolism in cell lines treated with doxorubicin and daunorubicin.

The role of metabolism in daunorubicin (DAUN)- and doxorubicin (DOX)-associated toxicity in cancer patients is dependent on whether the parent drugs or major metabolites, doxorubicinol (DOXol) and daunorubicinol (DAUNol), are the more toxic species. Therefore, we examined whether an association exists between cytotoxicity and the metabolism of these drugs in cell lines from nine different tissu...

Daunorubicin cardiotoxicity: evidence for the importance of the quinone moiety in a free-radical-independent mechanism.

Anthracyclines, such as daunorubicin (Daun), and other quinone-containing compounds can stimulate the formation of toxic free radicals. The present study tests the hypothesis that the quinone moiety of Daun, by increasing free-radical production, disrupts sarcoplasmic reticulum (SR) function and thereby inhibits myocardial contractility in vitro. We compared Daun with its quinone-deficient anal...

Two nonsynonymous single nucleotide polymorphisms of human carbonyl reductase 1 demonstrate reduced in vitro metabolism of daunorubicin and doxorubicin.

Carbonyl reductases (CBRs) are a group of metabolic enzymes belonging to the short-chain dehydrogenase family with NADPH-dependent oxidoreductase activity. These enzymes are known to metabolize the anthracyclines doxorubicin (DOX) and daunorubicin (DAUN). Both DOX and DAUN are highly effective in cancer therapy; however, there is considerable interpatient variability in adverse effects seen in ...
