Judul: In-Silico Testing of Active Compounds from Jasmine (Jasminum sambac) Leaves as Estrogen Antagonists against Estrogen Alpha Receptors
Abstrak: Daun melati memiliki aktivitas antikanker pada payudara yang telah diketahui menghambat pertumbuhan sel kanker MCF-7. Sel kanker ini mengekspresikan reseptor estrogen α yang penting pada kanker payudara. Oleh karena itu, penelitian ini bertujuan untuk menganalisis senyawa aktif pada daun melati yang menunjukkan aktivitas antikanker pada payudara khususnya terhadap reseptor estrogen α secara in-silico. Hasil penelitian menunjukkan bahwa terdapat senyawa potensial sebagai antagonis reseptor estrogen α pada daun melati yang memodulasi beberapa gen yang memiliki kemampuan untuk meregulasi kelangsungan hidup sel. Gen yang termodulasi tidak secara spesifik hanya mempengaruhi sel kanker payudara positif reseptor estrogen α., Jasmine leaves have been known to possess anti-breast cancer activity by inhibiting the growth of MCF-7 cancer cells. This cancer cell expressed the important estrogen receptor α in breast cancer. Therefore, this study aimed to analyze the active compounds in jasmine leaves that exhibit anticancer activity in breast cancer, particularly against the estrogen receptor α by in-silico approach. The results indicate the presence of potential compounds as estrogen receptor α antagonists in jasmine leaves, which can modulate several genes capable of regulating cell survival. The modulated genes however do not specifically target only breast cancer cells with positive estrogen receptor α.

Judul: Activity of breast anticancer of active compound from Spatholobus suberectus stem’s by in silico
Abstrak: Sekitar lebih 70% kasus kanker payudara adalah tipe positif hormon reseptor. Kasus kanker payudara tipe ini lebih banyak terjadi pada wanita post menopaus. Pengobatan yang efektif kasus ini adalah pemberian inhibitor enzim aromatase. Senyawa isoflavonoid batang Spatholobus suberectus telah teruji secara in vitro memiliki aktivitas sitotoksik terhadap sel kanker payudara MCF-7 yang banyak mengekspresikan reseptor estrogen dan enzim aromatase. Perlu dilakukan pencarian senyawa lain batang Spatholobus suberectus yang berpotensi memiliki aktivitas antikanker payudara. Penelitian ini bertujuan memprediksi potensi senyawa-aktif batang Spatholobus suberectus sebagai antikanker payudara melalui mekanisme penghambatan enzim aromatase secara in silico dengan metode penambatan molekular. Simulasi penambatan molekuler dilakukan melalui parameter energi ikat (ΔG), konstanta inhibisi (Ki), jenis interaksi dan binding site similarity (BSS). Senyawa aktif yang diprediksi memiliki potensi adalah prestegane B, 2R,3R-3,7-dihidroksiflavanon, dihidrorobinetin, asam protokatekuat etil ester, liquiritigenin, naringenin, 7,4’-dihidroksi-8-metoksi-isoflavone, asam protokatekuat, glisirosida, dulcisflavan, butein, hesperetin, plathymenin, isoliquiritigenin, dan medioresinol., Approximately over 70% of breast cancer cases are positive types of hormone receptors. Cases of this type of breast cancer are more common in post menopausal woman. An effective treatment of this case is the administration of aromatase enzyme inhibitors. The stem isoflavonoid compound Spatholobus suberectus has been tested in vitro has cytotoxic activity against MCF-7 breast cancer cells that expressed a lot of estrogen receptors and aromatase enzymes. It is necessary to search for other compounds of Spatholobus suberectus stem that have the potential to have anticancer activity of the breast. This study aimed to predict the potential of compound-active stem Spatholobus suberectus as an anticancer breast through the mechanism of inhibition of aromatase enzymes in silico by molecular docking method. Molecular tethering simulation is done through binding energy parameters (ΔG), inhibition constants (Ki), types of interaction and binding site similarity (BSS). Active compounds that was predicted to have potential are prestegane B, 2R,3R-3,7-dihydroxyflavanon, dihydrorobinetin, protocatechuic acid ethyl ester, liquiritigenin, naringenin, 7,4’-dihidroksi-8-metoksi-isoflavone, protocatechuic acid, glyciroside, dulcisflavan, butein, hesperetin, plathymenin, isoliquiritigenin, and medioresinol.

Judul: Manajemen Pemeliharaan Kuda (Equus caballus) Untuk Upacara Kenegaraan Dan Sarana Kesenjataan Di Detasemen Kavaleri Berkuda (DenKavkud) TNI-AD Parongpong
Abstrak: Cavalry Horse Detachement (Denkavkud) Indonesian National Army-Cavalary Parongpong is one of the Indonesian military units that utilize the horse and train it as a means of purpose of formal state ceremony and armed forces. Skills possessed by the horse cavalry was the result of care management and specialized training provided by the trainer. Aspects of care management are breeding, feeding, and management. Horses that are kept in the Denkavkud, Parongpong are stallions, mares, foals, and military horses. Total populations of horses at Denkavkud are 183 horses. Besides commited horse training (remonte), Denkavkud also did breeding program to produce horses that can be trained and used as a military horse. There are some issues contained in Denkavkud, such as some of the nutrients needed by the horses not being met from feed given. One of these is crude protein and lysine. Lactation mares was crude protein and lysine deficiency. The number of death in 2010 is higher than previous years. Based on the number of horses that died from January until June 2010 is 11 horses. The average mortality was caused by colic. Colic is caused by excessive eating, excessive drinking during hot, moldy food, and even by investment roundworms. Animal welfare in Denkavkud can be enhanced by improvement of feed given and improving the health of livestock through improved sanitation.
