BACKGROUND Determining the correct number of positive immune cells in immunohistological sections of colorectal cancer and other tumor entities is emerging as an important clinical predictor and therapy selector for an individual patient. This task is usually obstructed by cell conglomerates of various sizes. We here show that at least in colorectal cancer the inclusion of immune cell conglomer...

Self-assembly reactions between di- and tritopic gold(i) metallaligands bearing terminal pyridine rings Pd(ii) or Pt(ii) fragments produce heterometallic macrocycles cages with cavities of different sizes shapes.

Abstract Gold mobilization, transfer, and concentration in the Earth’s crust are controlled by hydrothermal sulfur- chloride-bearing fluids. Yet exact chemical identity, structure, stability of Au-bearing species and, particular, respective contributions sulfide (HS−) trisulfur ion (S3⋅−) ligands to Au transport lack direct situ evidence. Here we employed high energy resolution fluorescence det...

* Group Treasurer, Colonial Limited. 1 The Tripartite Group of Banking, Securities and Insurance Regulators defined a financial conglomerate as “any group of companies under common control whose exclusive or predominant activities consist of providing significant services in at least two different financial sectors (banking, securities, insurance)” (see Tripartite Group of Banking, Securities a...

The core of detrital zircons from the southern Meiganga gold-bearing placers were analyzed by Laser Ablation Split Stream analytical techniques to determine their trace element abundances and U-Pb ages. obtained data used characterize each grain, its formation condition, try provenance. Hf (5980 12,010 ppm), Y (27–1650 U (25–954 Th (8–674 Ti (2–256 Ta, Nb, Sr (mainly <5 Th/U (0.06–2.35), zir...

One of the applications of gold nanoparticles (GNPs) in medicine is radiation dose-enhancing effect. Although there are many simulations, in vitro and in vivo evidence that GNPs can enhance significantly the radiation dose effect of orthovoltage beams. These beams compared with megavoltage (MV) beams, have limited applications in radiotherapy. In order to evaluate GNPs radiosensitization perfor...

In the established technologies, use of classic depressants pyrite, such as lime represents one main problems in flotation gold-bearing copper (Cu) ores. Lime addition leads to depression noble metals - gold (Au) and silver (Ag) that end up tailings. Thus, operator incurs economic losses. The current paper presents research aimed at replacing pyrite ore, bearing silver, classical depressor with...
