Judul: Kebiasaan Makan, Aktivitas Fisik, Dan Kebugaran Pada Anak Sekolah Dasar Dengan Status Gizi Normal Dan Lebih Di Kota Bogor.
Abstrak: Tujuan penelitian ini adalah menganalisis kebiasaan makan, aktivitas fisik, dan kebugaran anak sekolah dasar dengan status gizi normal dan lebih di Kota Bogor. Desain yang digunakan adalah cross sectional study, dilaksanakan pada bulan Maret-Juni 2014, di SDN Polisi 1 dan SDIT At Taufiq. Contoh penelitian terdiri dari 62 anak gizi normal dan 38 anak gizi lebih. Data yang digunakan merupakan data sekunder. Analisis statistik yang digunakan adalah uji beda Mann Whitney, dan Independent sample T test serta uji korelasi Spearman dan Chi-squre. Hasil penelitian menunjukkan bahwa asupan energi (p=0.003), asupan protein (p=0.000), asupan lemak (p=0.008), serta tingkat kecukupan protein (p=0.033) pada contoh gizi lebih, lebih tinggi daripada contoh gizi normal. Status gizi contoh memiliki hubungan signifikan positif dengan asupan energi (p=0.015, r=0.242) dan asupan lemak (p=0.044, r=0.202), namun memiliki hubungan signifikan negatif dengan kebugaran (p=0.005, r=-0.282). Tidak ada hubungan yang signifikan antara tingkat aktivitas fisik dengan kebugaran (p>0.05).

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
