We present the case of a 40-year-old male with multiple myeloma for whom bone marrow scintigraphy was utilized to help differentiate between active bony myelomatous disease versus treated lesions with compensatory marrow uptake. This case demonstrates technetium (Tc-99m) sulfur colloid imaging as an inexpensive technique to quickly distinguish between active focal bone disease and reactive marrow.

Janus colloids propelled by light, e.g., thermophoretic particles, offer promising prospects as artificial microswimmers. However, their swimming behavior and its dependence on fluid properties and fluid-colloid interactions remain poorly understood. Here, we investigate the behavior of a thermophoretic Janus colloid in its own temperature gradient using numerical simulations. The dissipative p...

The superconducting proximity effect is investigated for SN double layers in a regime where the resulting transition temperature Tc does not depend on the mean free paths of the films and, within limits, not on the transparency of the interface. The experimental results for Tc are compared with a numerical evaluation which was recently developed in our group. The results for the SN double layer...

UNLABELLED The purpose of this study was to compare the results of isotope injection the morning of surgery (1-d protocol) with isotope injection the day before surgery (2-d protocol) in patients having sentinel lymph node (SLN) biopsy for breast cancer. METHODS The 1-d (protocol 1) and 2-d (protocol 2) protocols included 514 and 152 patients, respectively, treated contemporaneously by surgeo...

Scanning tunneling microscopy studies reveal that trace amounts of adsorbed S below a critical coverage on the order of 10 mML have little effect on the coarsening and decay of monolayer Ag adatom islands on Ag(111) at 300 K. In contrast, above this critical coverage, decay is greatly accelerated. This critical value appears to be determined by whether all S can be accommodated at step edges. A...

According to the Air Quality Framework Directive, air pollutant concentration levels have to be assessed and reported annually by each European Union member state, taking into consideration European air quality standards. Plans and programmes should be implemented in zones and agglomerations where pollutant concentrations exceed the limit and target values. The main objective of this study is t...

The sea breeze/land breeze circulation system in the Los Angeles a r ea results in transport of pollutants seaward at nigh t followed by return of aged material inland the next day . This characteristic wind reversal pattern both increases the r etention time available for the oxidation of S02 to form sulfates and causes individual a ir parcels to make mul tiple passes over large coas tal emiss...

A catalytic, enantioselective decarboxylative allylic alkylation of 4-thiopyranones is reported. The α-quaternary 4-thiopyranones produced are challenging to access by standard enolate alkylation owing to facile ring-opening β-sulfur elimination. In addition, reduction of the carbon-sulfur bonds provides access to elusive acyclic α-quaternary ketones. The alkylated products are obtained in up t...
