Abstrak :
Pemilihan oosit merupakan salah satu tahap penting dalam fertilisasi in vitro (FIV) sebab semakin banyak jumlah oosit yang masuk kualifikasi, maka semakin besar kesempatan oosit tersebut untuk difertilisasi. Growth Differentiation Factor 9 (GDF9) dan Bone Morphogenetic 15 (BMP15) yang merupakan anggota dari superfamili protein Transforming Growth Factor β (TGF-β), memiliki peranan penting terhadap folikulogenesis. Gen gdf9 dan bmp15 diketahui tidak hanya terekspresikan pada oosit, namun juga pada sel granulosa dan cairan folikel. Oleh karena itu, dilakukan penelitian mengenai ekspresi gen gdf9 dan bmp15 pada sel granulosa dan cairan folikel untuk mengetahui pengaruhnya terhadap kualitas oosit. Lima belas sampel sel granulosa dan cairan folikel dikumpulkan untuk mengukur ekspresi gen gdf9 dan bmp15 secara kuantitatif. Metode kuantifikasi absolut digunakan untuk mengukur tingkat ekspresi gen. Uji korelasi Pearson digunakan untuk menganalisis korelasi antara ekspresi gen gdf9 dan bmp15 terhadap parameter umum fisiologis. Ekspresi gen gdf9 pada sel granulosa memiliki korelasi lemah searah tak signifikan (P>0,05) terhadap umur, tingkat kematangan oosit, tingkat fertilisasi normal, dan tingkat pembelahan. Ekspresi gen bmp15 memiliki korelasi lemah searah tak signifikan (P>0,05) terhadap umur serta memiliki korelasi lemah tak searah tak signifikan (P>0,05) terhadap tingkat kematangan oosit, tingkat fertilisasi normal, dan tingkat pembelahan. Ekspresi gen gdf9 dan bmp15 pada cairan folikel tidak dapat dianalisis sebab kurva standar tidak terkonstruksi.
Oocyte selection is one of important steps in in vitro fertilization (IVF) procedures, because more number of qualified oocyte will bring its chance to be fertilized bigger. Growth Differentiation Factor 9 (GDF9) dan Bone Morphogenetic 15 (BMP15) are members of protein superfamily Transforming Growth Factor β (TGF-β) which have important role in folliculogenesis. Gdf9 dan bmp15 genes are not only expressed in oocyte, but in granulosa cell and follicular fluid too. Research has been conducted about gdf9 and bmp15 gene expression in granulosa cell and follicular fluid to know their association with oocyte quality. Fifteen samples of granulosa cell and follicular fluid were collected to measure gdf9 and bmp15 gene expression quantitatively. Absolute quantification method were used to measure gene expression levels. Pearson correlation was used to analize correlation between both gene expression levels and general physiological parameters. The expression levels of gdf9 in granulosa cell had weak positive unsignificant (P>0,005) correlation with age, oocyte maturity rate, normal fertilization rate, and cleavage rate. The expression levels of bmp15 in granulosa cell had weak positive unsignificant (P>0,005) correlation with age, but had weak negative unsignificant (P>0,005) correlation with oocyte maturity rate, normal fertilization rate, and cleavage rate. Gdf9 and bmp15 gene expression in follicular fluid cannot be analized because the standard curve could not be constructed.

Abstrak :
Stem Cell Labeling for Delivery and Tracking Using Noninvasive Imaging provides a comprehensive overview of cell therapy imaging, ranging from the basic biology of cell therapeutic choices to the preclinical and clinical applications of cell therapy. It emphasizes the use of medical imaging for therapeutic delivery/​targeting, cell tracking, and determining therapeutic efficacy. The book first presents background information and insight on the major classes of stem and progenitor cells. It then describes the main imaging modalities and state-of-the-art techniques that are currently employed for stem cell tracking. In the final chapters, leading scholars offer clinical perspectives on existing and potential uses of stem cells as well as the impact of image-guided delivery and tracking in major organ systems. Through clear descriptions and color images, this volume illustrates how noninvasive imaging is used to track stem cells as they repair damaged tissue in the body. With contributions from some of the most prominent preclinical and clinical researchers in the field, the book helps readers to understand the evolving concepts of stem cell labeling and tracking as the field continues to move forward.

ABSTRAK
Penelitian yang bertujuan untuk mengetahui pengaruh variasi pH awal medium CT terhadap kerapatan sel Cyanobacteria genus Synechococcus HS-7 dan HS-9 yang diinkubasi pada suhu 35 C telah dilakukan. Penelitian dilakukan selama 22 hari dari hari ke-0 t0 hingga hari ke-21 t21 . Penghitungan kerapatan sel dilakukan setiap hari t0 mdash;t21 , sedangkan pengukuran kandungan klorofil dilakukan selama 10 hari pada t0, t1, t2, t3, t4, t7, t10, t14, t17, dan t21. Terdapat 5 variasi perlakuan pH yang digunakan, yaitu pH 5, pH 6, pH 7, pH 8, dan pH 9. Setiap perlakuan dilakukan 3 kali pengulangan. Pengamatan dilakukan secara kualitatif dan kuantitatif. Data yang diperoleh kemudian diuji menggunakan analisis statistika Spearman dan Friedman. Hasil penelitian menunjukkan bahwa variasi pH awal medium CT berpengaruh terhadap kerapatan sel Synechococcus HS-7 dan HS-9. Synechococcus HS-7 dan HS-9 dapat tumbuh baik pada pH 7. Berdasarkan uji analisis statistik, terdapat korelasi antara kerapatan sel dengan kandungan klorofil Synechococcus HS-7 dan HS-9, serta nilai pH awal medium CT yang berbeda tidak berpengaruh terhadap kerapatan sel Synechococcus HS-7 dan HS-9.
ABSTRACT
Research that aims to know the effect of initial pH variation of CT medium to the cell density of Cyanobacteria genus Synechococcus HS 7 and HS 9 were grown at temperature 35 C had been performed. The study was done for 22 days from day 0 t0 to day 21 t21 . Cell density calculations were performed everyday t0 mdash t21 while the measurement of chlorophyll content was performed for 10 days at t0, t1, t2, t3, t4, t7, t10, t14, t17, and t21. There were 5 variations of pH that used in this research pH 5, pH 6, pH 7, pH 8, and pH 9 . Each treatment carried out in 3 replications. Observations were done qualitatively based on the cell density while quantitatively based on statistical analysis using Spearman and Friedman tests. The results showed that the initial pH variation of CT medium affected the growth of Synechococcus HS 7 and HS 9. Synechococcus HS 7 and HS 9 grew well at pH 7. Based on statistical analysis there were correlation between the cell density and chlorophyll content, and the initial pH variation of the CT medium did not affect the growth of Synechococcus HS 7 and HS 9.
