THE IMPROVEMENT OF SEMEN QUALITY AND TESTOSTERONE LEVEL OF BALI CATTLE AFTER PROSTAGLANDIN F2α ADMINISTRATION

This study aimed to determine the effect of prostaglandin F2α (PGF2α) administration on improving semen quality and testosterone levels on Bali cattle. This study used 3 Bali cattle aged 2, 3.5, and 5 years old. The sample used in this study was Bali cattle semen. In this study, the Latin Square Design was used with three different treatments were administered over three time periods. The treatments performed were P1 (5 mL physiological NaCl), P2 (25 mg prostaglandin), and P3 (37.5 mg prostaglandin) while treatment period was three weeks of treatment administration, which were 1st. 2nd, and 3rd week. Blood collected through coccygea vein 30 minutes after treatment to measure testosterone levels using enzyme-linked immunosorbent assay (ELISA) technique. Statistical analysis showed that PGF2α administration at a dose of 25 mg and PGF2α at a dose of 37.5 mg had no effect (P0.05) on volume, color, pH, consistency, concentration, and motility of Bali cattle spermatozoa. The volume of semen obtained from P1; P2; and P3 were 6.5±0.9; 6.3±0.6; and 6.2±1.2 mL, respectively. The color of the semen in P1, P2, and P3 were beige and milky white. The pH in groups P1; P2; and P3 were 6.7±0.6; 7.1±0.2; and 6.5±0.2, respectively. Spermatozoa concentration in P1; P2; and P3 were 1,328±96.43 x 106 cells/mL; 1,354±102.19 x 106 cells/mL; and 1,353.3±88.55 x 106 cells/mL, respectively. Spermatozoa motility in P1; P2; and P3 were 73.3±2.8%; 71.6±2.8%; and 73.3±2.8%, respectively. Testosterone levels in P1 and P3 were 5.05±0.22 and 6.74±1.38 ng/mL, respectively (P0.05). Based on the results of this study, it was concluded that the administration of PGF2α does not affect semen quality but can increase the level of testosterone on Bali cattle

MicroRNA-21 as a biomarker for ovarian cancer detection

Ovarian cancer is a lethal disease. One of the problems faced by patients with ovarian cancer is the lack of symptoms in its early stages, which results in it only being detected when it is at an advanced stage. Therefore, there is an urgent need for biomarkers that can predict ovarian cancer precisely. The purpose of this study was to determine the expression of microRNA-21 as a predictive biomarker candidate in both early- and advanced-stage ovarian cancer. This was a cross-sectional study using the blood plasma of 21 healthy control subjects and 37 blood plasma samples from patients with ovarian cancer. Blood plasmas were collected, from which the RNA was isolated. Based on the RNA, the cDNA was synthesized and run through qPCR, the results of which were analyzed using the Livak method. The results showed an upregulation of microRNA-21 in the advanced stage by 2.14 fold compared with the early stage, and 6.13 fold compared with the healthy controls (p < 0.05). The upregulation of microRNA-21 in early-stage ovarian cancer was 2.86 fold compared with the healthy control subjects (p < 0.05). In addition, there was an increase in the expression of microRNA-21 in ovarian cancer by 4.14 fold compared with the healthy controls (p < 0.05). Based on these results, it can be concluded that the expression of microRNA 21 upregulated with the severity of the disease

Seismic performance of brick masonry infilled frame structures with bed joint reinforcements

This paper presents the evaluation of the seismic performance of brick infilled RC frame structures with bed joint reinforcements based on reversed cyclic lateral load tests. Three specimens of the structural model of 1/4 scale-down single-story single-bay brick infilled RC frame was prepared, which were brick infilled RC frames with and without bed joint reinforcements. Two specimens of brick infills with bed joint reinforcements were different in the spacing of bed joint rebars. The specimens were tested by applying a reversed cyclic lateral loading in-plane direction. During the tests, the crack propagation was observed at the peak and residual drifts of each loading cycle to recognize the failure mechanisms of the specimens. As the results, although the use of the bed joint reinforcements ineffective to increase the lateral strength of the overall infilled frame structure. The rebars in mortar bed joints role to sustain the lateral strength in plastic deformation, and provide the whole structure with high ductility. It seemed that the rebars in mortar bed joints confined the brick infills. Therefore, the infilled RC frames can survive in large deformation without failure of the infills in out of the plane direction
