parathyroid adenoma involving a single parathyroid gland is the underlying cause of 80-85% of primary hyperparathyroidism (phpt). skeletal system is significantly affected by phpt. brown tumors are known to have affinity for 99mtc-mibi. we report a rare case of phpt presenting with diffuse bony pain, high calcium level and significantly elevated alkaline phosphatase level. 99mtc-pertechnetate/9...

Hepatitis C Virus (HCV) encodes two envelope glycoproteins, E1 and E2. Our previous work selected a specific aptamer ZE2, which could bind to E2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting HCV. In this study, the binding sites between E2 and aptamer ZE2 were further explored. E2 was truncated to 15...

Protein specific aptamers are highly applicable affinity ligands in different fields of research and clinical applications. They have been developed against various targets, in particular, bio-macromolecules such as proteins. Among human proteins, the coagulation factors are the most attractive targets for aptamer selection and their specific aptamers had valuable characteristics in therapeutic...

background: plasminogen is one of the compounds derived from human plasma. activation of plasminogen produces plasmin. plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. the aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine sepharose. materials and methods: normal human plasma was used as the start...

Single molecule fluorescence tracking provides information at nanometer-scale and millisecond-temporal resolution about the dynamics interaction of individual molecules in a biological environment. While dynamic behavior isolated can be characterized well, quantitative insight is more limited when interactions between two indistinguishable occur. We address this aspect by developing theoretical...

Under what conditions do judiciaries act assertively against authoritarian regimes? I argue that the judiciary coalesces around institutional norms and preferences in response to of institutions networks, or "audiences," with which judges interact, shape careers reputations judges. Proposing a typology judicial-regime relations, demonstrate judiciary's affinity regimes diminishes as these audie...

the affinity of low density lipoprotein (ldl) to its receptor is very important, because most of ldl-uptake pathway is done by the ldl receptor and the change in size of ldl particle and the modification in its components may affects the ldl affinity for its receptor. in this study, the effects of lipophilic agents such as vitamin e and seven volatile oils: anethol, eugenol, geraniol, limonene,...
