Recently, asbestos-related diseases have become serious all over the world. We investigated the condition of asbestos in large-scale buildings. The survey was performed in 2006 in Kitakyushu with self-administered questionnaires which were sent to managers of 250 buildings. We received 150 answers. Eighteen buildings out of 150 used chrysotile or crocidolite, and 6 buildings out of 18 took measures to deal with the situation. The number of buildings where asbestos was used increases with the age of the buildings. The older the buildings are, the more buildings used asbestos, probably reflecting the extent of legal regulations and recognition of the harmfulness of asbestos. Twenty-one buildings out of 150 gave education on asbestos, 9 buildings out of 21 buildings used asbestos, and half the buildings didn't give education on asbestos. These results suggest that the measures against and education on asbestos are insufficient in large-scale buildings.

The effect of feeding spray dried porcine plasma (SDPP) to male turkeys during the first 4 weeks of life was evaluated at 20 weeks of age. A total of 648 male Hybrid Converter day-old turkeys were divided into two groups of 9 replicate pens of 36 birds each, and fed a commercial-type program of 7 diet phases. In phase 1 birds were fed a corn-soybean meal Control diet for 4 weeks, or a diet with 2% SDPP of similar nutrient density.

Vibrational Stark effect (VSE) spectroscopy has become one of the most important experimental approaches to determine the strength of noncovalent, electrostatic interactions in chemistry and biology and to quantify their influence on structure and reactivity. Nitriles (C≡N) have been widely used as VSE probes, but their application has been complicated by an anomalous hydrogen bond (HB) blueshift which is not encompassed within the VSE framework. We present an empirical model describing the anomalous HB blueshift in terms of H-bonding geometry, i.

The capture of carbon dioxide (CO) is crucial for reducing greenhouse emissions and achieving net-zero emission goals. Metal-organic frameworks (MOFs) present a promising solution for carbon capture due to their structural adaptability, tunability, porosity, and pore modification. In this research, we explored the use of a copper (Cu(II))-based MOF called .

Targeting iron metabolism has emerged as a novel therapeutic strategy for the treatment of cancer. As such, iron chelator drugs are repurposed or specifically designed as anticancer agents. Two important chelators, deferasirox (Def) and triapine (Trp), attack the intracellular supply of iron (Fe) and inhibit Fe-dependent pathways responsible for cellular proliferation and metastasis.

Metallogels built in a bottom-up approach by metal coordination and supramolecular interactions have important potential for the elaboration of smart materials. In this context, we present here the formation of supramolecular coordination polymers driven by the complexation of cobalt(II) or zinc(II) ions with polyoxometalate-based hybrids displaying two terpyridine ligands in a linear arrangement. Thanks to the electrostatic interactions between the polyoxometalate cores and metal nodes, the polymer chains self-assemble into fibers that physically cross-link to form gels above a critical concentration.
