Nuclear Geophysics is essential to the oil, gas and uranium industries. The initial development of nuclear geophysics was focused on developing techniques needed by the oil industry. Developments in nuclear physics and computational analysis were immediately used this field. Today, techniques developed in nuclear geophysics are also used by the coal and metalliferous mining industries and contr...

The present study describes glucocorticoid induced remodelling of nuclear envelope (NE) structure and permeability. A glucocorticoid analogue, triamcinolone acetonide (TA), is injected into Xenopus laevis oocytes that express an exogeneous glucocorticoid receptor (GR). Electrical, fluorescence and nano-imaging techniques are applied to study the permeability and the structure of the NE at 5 and...

The Japanese Society of Nuclear Medicine has recently published the consensus guidelines for pediatric nuclear medicine. This article is the English version of the guidelines. Part 1 proposes the dose optimization in pediatric nuclear medicine studies. Part 2 comprehensively discusses imaging techniques for the appropriate conduct of pediatric nuclear medicine procedures, considering the charac...

Nuclear medicine is a diverse field with a large number of different studies spanning virtually all organ systems and medical specialties. Many nuclear medicine procedures are performed routinely; others may be performed only rarely, sometimes less than once per year. The infrequent nature of many studies makes it challenging to retain relevant knowledge and skills. This 2-part article provides...

The long term goal of the Nuclear Receptor Signaling Atlas (NURSA) resides in unraveling the physiological and pathological functions of nuclear receptors (NRs) at the molecular, biochemical and cellular levels. This multi-oriented task requires complementary approaches in order to determine the specific function(s) and precise expression and receptor activity patterns for each individual conve...

The nuclear transfer process is one of the critical rate-limiting processes in transgene expression. In the present study, we report on the effect of compaction and the size of the DNA molecule on nuclear transfer efficiency by microinjection. A DNA/protamine complex- or variously-sized naked DNA molecules were injected into the cytoplasm or nucleus of synchronized HeLa cells. To evaluate the n...
