These are rough notes for the Fall 2015 course. Solutions to problem sets were posted on an internal website.

Purpose: To evaluate the performance of Biograph Vision Quadra (Siemens Healthineers) PET/CT system. This new system is based on Siemens 600, using same silicon photomultiplier-based detectors with 3.2×3.2×20-mm lutetium-oxoorthosilicate crystals. The Quadra’s 32 detector rings provide a fourfold larger axial field view (AFOV) 106 cm, enabling imaging major organs in one bed position. <b...

We present the detection of type C quasi-periodic oscillation (QPO) along with upper harmonic at respective frequencies $$\sim $$ 0.6 Hz and 1.2 in single AstroSat observation taken during 2016 outburst low-mass black hole X-ray binary H 1743-322. These are found to be shifted by 0.4 for QPO 0.8 respect that simultaneous XMM-Newton NuSTAR five days later than observation, indicating a certain g...

The binding interaction between the Nck2 SH2 domain and the phosphorylated ephrinB initiates a critical pathway for the reverse signaling network mediated by Eph receptor-ephrinB. Previously, the NMR structure and Tyr phosphorylations of the human ephrinB cytoplasmic domain have been studied. To obtain a complete story, it would be of significant interest to determine the structure of the Nck2 ...

The ability to determine coreceptor usage of patient-derived human immunodeficiency virus type 1 (HIV-1) strains is clinically important, particularly for the administration of the CCR5 antagonist maraviroc. The envelope glycoprotein (Env) determinants of coreceptor specificity lie primarily within the gp120 V3 loop region, although other Env determinants have been shown to influence gp120-core...

Enterococcus gallinarum BM4175 (a vancomycin-susceptible derivative of BM4174 obtained by insertional inactivation of vanC-1) was transformed with plasmid constructs pCA10 (containing the genes necessary for resistance, vanC-1-XYc-T), pJP1 (with a fragment lacking the DNA encoding the transmembrane region of VanT, -vanC-1-XYc-T((Delta))(2-322)-) and with plasmids containing fragments encoding e...
