Literature reports of the efficacy of para-sulfonatocalix[6]- and calix[8]-arenes as U(vi) complexants indicated that they might be useful for in vivo chelation of the novel therapeutic alpha-emitter (230)U. We have studied the complexation of U(vi) with para-sulfonatocalix[6]arene and para-sulfonatocalix[8]arene by time resolved laser induced fluorescence spectroscopy and using competition met...

A high-current, wide-band transconductance amplifier is described that provides an unprecedented level of output current at high frequencies with exceptional stability. It is capable of converting a signal voltage applied to its input into a groundreferenced output rms current up to 100 A over a frequency range from dc to 100 kHz with a useable frequency extending to 1 MHz. The amplifier has a ...

Pemeriksaan Deoxyribonucleic Acid merupakan metode identifikasi primer dalam kasus forensik. Bercak darah yang ditemukan di tempat kejadian perkara seringkali terpengaruh oleh berbagai faktor lingkungan salah satunya sinar ultraviolet dari matahari. Tujuan penelitian ini yaitu membandingkan kuantitas dan kualitas DNA hasil ekstraksi bercak pada pisau pasca paparan matahari selama 0, 15 30 hari....

We performed a paternity test in a case of incest between brother and sister. DNA from blood samples of the alleged parents and their two children was obtained with Chelex DNA extraction method and quantified with Applied Biosystems QuantiBlot quantitation kit. Polymerase chain reaction (PCR) amplification of DNA samples was performed with AmpFlSTR SGM Plus PCR amplification kit and GenePrint P...

A simple method for viral DNA extraction using chelex resin was developed. The method used was eco-friendly and cost effective compared to other methods such as phenol chloroform method which use health hazardous organic reagents. Further, a polymerase chain reaction (PCR) based detection of canine parvovirus (CPV) using primers from conserved region of VP2 gene was developed. To increase the s...
