High Glucose, But Not Testosterone, Increases Platelet Aggregation Mediated by Endothelial Cells

Endothelial cells inhibit platelet aggregation by releasing thromboregulators, such as prostacyclin and nitric oxide. Male subject is a traditional risk factor for cardiovascular diseases. Platelet hyperreactivity has been frequently found in patient with diabetes mellitus. To examine whether testosterone and high glucose modify platelet aggregation through endothelial cells, we did an in vitro study using endothelial cells culture from human umbilical vein (HUVEC). Treatments were performed in HUVEC sub culture as either normoglucose (5.6 mM) or high glucose (22.4 mM) medium, with or without testosterone (0, 1, 10, 100 nM), for 24 hours. HUVEC were trypsinized, resuspended, and then incubated with platelet rich plasma from healthy male donors with ratio 1:104 for 3 minutes. Platelet aggregation measured by turbidimetry methode. This study showed that testosterone did not significantly influence platelet aggregation through endothelial cells in normoglucose (p = 0.144) or high glucose (p = 0.916) medium. There was no main effect of testosterone (p = 0.73) as well as no interaction between testosterone and glucose (p = 0.69), but there was a main effect of glucose (p = 0.004), to platelet aggregation through endothelial cells. In conclusion, high glucose, but not testosterone, inhibits platelet aggregation mediated by endothelial cells

Desain Eksperimen Untuk Mengoptimalkan Proses Pengecoran Saluran Keluar Teko

The most frequently found defect in the casting process of making teapots out flue is that the outlet is too narrow or even blocked at the end of the casting process. There are many factors influence that defect. This defect condition can be represented as the thickness of the casting product. In this paper, the significant factors that influence the thickness of the out flue resulted from the casting process will be analyzed and further got their optimum conditions. Design experiments methods will be implemented here, especially the factorial design method to determine the significant factors along with their optimum conditions. Also, the response surface method will be applied to obtain the approximation model for the thickness of the out flue as a function of the factors found earlier so that the most optimal result can be obtained under a design optimization method. It is concluded from the experiments results and analysis that the significant factors for the thickness of out flue are pouring temperature, sprue radius and holding time. The optimum conditions of those factors are 475°C, 29.6 mm and 8 seconds respectively with 2.54 mm thickness

Sintesis protein mikrobia sapi perah peranakan friesian holstein yang diberi pakan basal rumput raja, jerami jagung dan jerami padi dengan suplementasi konsentrat protein tinggi=Rumen microbial protein synthesis ofHolste

ABSTRACT Fifteen Dairy cattle of Holstein Crossbred heifer were used for estimating rumen microbial protein synthesis. The cattle fed by a single diet of King Grass (KG), Corn Stover (CS) or rice straw (RS) ad libitum as basal diet that was supplemented by a high protein concentrate. Microbial protein synthesis were estimated from derivatives concentration. Data obtained: microbial protein synthesis (MPS) were analyzed using analyses of variance, in split plot and completely randomized design. The means differences were analyzed by DMRT. The result of this research showed that purin derivatives concentration of cattle fed on KG, CS, and RS were 75.0767.72 and 61.88 mmol/day, respectively. The production of microbial protein synthesis values were respectively 55.79,49.43 and 44.35 gN/day and it was significantly different among diet (PO.01). The Duncan test showed that KG\u27s diet was the highest followed by CS\u27s diet and RS\u27s was the lowest. Keywords: Dairy cattle, high protein concentrate, rumen microbial protein synthesis

SUPLEMENTASI MINYAK BIJI KAPOK TERPROTEKSI UNTUK MENINGKATKAN PRODUKTIVITAS DOMBA LOKAL JAWA EKOR KURUS

ABSTRAK Penelitian dilakukan untuk menghetahui pengaruh suplementasi minyak biji kapok (MBK) sebagai sumber asam lemak tak jenuh ganda (ALTJG) terproteksi terhadap utilitas pakan serta dampaknya pada produktivitas ternak domba lokal jawa ekor kurus (JEK). Sebagai bahan percobaan, digunakan 24 ekor domba lokal JEK jantan yang terbagi dalam 8 kelompok perlakuan, masing-masing terdiri atas 3 ekor sebagai ulangan. Melalui penelitian yang menggunakan 2 faktor perlakuan ini, dikaji pengaruh suplementasi MBK terproteksi dalam kombinasinya dengan konsentrat (K), dalam hal ini adalah bekatul (Bkt) terhadap performans ternak domba yang mendapat pakan basal berupa RL. Faktor 1 terdiri atas 2 perlakuan, yakni S1 (suplementasi MBK dengan aras 10% dan proteksi dengan aras 75%) dan S0 (tanpa suplementasi MBK). Faktor 2 berupa 4 aras pemberian konsentrat, masing-masing 0% (K0), 15% (K1), 30% (K2) dan 45% (K3) dari jumlah konsumsi bahan kering (BK) pakan. Variabel yang diukur meliputi konsumsi dan kecernaan ransum serta performans ternak domba. Data yang terkumpul diolah dengan analisis varians dalam rancangan acak lengkap (RAL), dilanjutkan uji beda nilai tengah dengan uji jarak dari Duncan. Rata-rata pertambahan bobot badan harian (PBBH) domba yang mendapat Bkt lebih tinggi (P < 0,05) daripada yang hanya mndapat RL saja (54 g pada S0K0, vs 62; 82 dan 89 g pada S0K1, S0K2 dan S0K3). Suplementasi MBK tanpa Bkt (S1K0) menghasilkan PBBH lebih tinggi (P<0,05) daripada S0K0 (60 vs 54 g). Nilai PBBH tertinggi dicapai pada S1K2, yakni 99 g dengan persentase karkas dan nisbah daging/tulang (NDT) 40,12% dan 3,60. Peningkatan Bkt lebih lanjut (S1K3) menghasilkan PBBH cenderung lebih rendah, yakni 95 g dengan persentase karkas dan NDT 40,27% dan 3,56. Suplementasi MBK terproteksi dalam kombinasinya dengan Bkt meningkatkan konsumsi BK, PBBH, persentase karkas dan NDT.
