All too often, waste authorities either assume that they know enough about their bulky waste stream or that it is too insignificant to deserve attention. In this paper, we use Hong Kong as an example to illustrate that official bulky waste figures can actually be very different from the reality and therefore important waste management decisions made based on such statistics may be wrong too. Th...

INTRODUCTION Poor prognosis patients with bulky stage III locally advanced non-small-cell lung cancer may not be offered concurrent chemoradiotherapy (CRT). Following a phase III trial concerning the effect of palliative CRT in inoperable poor prognosis patients, this analysis was performed to explore how tumor size influenced survival and health-related quality of life (HRQOL). METHODS A tot...

Urothelial carcinomas have an established propensity for divergent differentiation. Most of these variant tumors are muscle invasive but not all. The response of non muscle invasive variant tumors to intravesical immunotherapy with BCG is not established in the literature, and is reported here. Between June 1995 and December 2007, 760 patients (mean age of 67.5 years) underwent transurethral re...

A variety of novel imidazolidinone-based organocatalysts with bulky substituents were synthesized under mild reaction conditions starting from easily accessible substrates. Different natural and unnatural amino acid methyl amides were cyclized with aromatic carbaldehydes to yield two diastereomeric MacMillan-type catalysts. Special emphasis was put on bulky residues such as mesityl and pyrene m...

Malignant mesothelioma is an aggressive and lethal pleural cancer that overexpresses transforming growth factor B (TGFB). We investigated the efficacy of a novel small-molecule TGFB type I receptor (ALK5) kinase inhibitor, SM16, in the AB12 syngeneic model of malignant mesothelioma. SM16 inhibited TGFB signaling seen as decreased phosphorylated Smad2/3 levels in cultured AB12 cells (IC50, f200 ...

Dendronized polymers exhibit defined structures with bulky side chains (dendrons) on a linear polymer backbone. Upon reaction with radicals, chromophores close to the backbone were bleached. The reaction rate and yield decreased with increasing dendron size, demonstrating that the inside of dendronized polymers can be "shielded" by bulky dendrons from access by reactive species.

The stereospecific hydrolysis of bulky aminophosphine boranes is reported for the first time. The resulting phosphinous acid boranes, upon activation, undergo stereospecific nucleophilic substitution reaction at the phosphorous center with amine nucleophiles. The combination of these two processes provides a novel access to bulky P*-ligands.

Bulky alkylzinc complexes, (Ttz(tBu,Me))ZnMe and (Ttz(tBu,Me))ZnEt, show remarkable stability towards water and both complexes crystallize with one molecule of adventitious water hydrogen bonded to two triazole rings; in contrast the less bulky complex, (Ttz(Ph,Me))ZnEt, reacts with water to yield (Ttz(Ph,Me))(2)Zn.

The concept of splayed, hyperthin polyelectrolyte multilayers (PEMs) is introduced in which a bulky, hydrophilic and charged pendant group is used to increase the gas permeability of a PEM without reducing its permeation selectivity. Proof of principle studies are reported using nm-thick PEMs made from poly(sodium 4-styrene sulfonate) () and poly(allylamine hydrochloride) () bearing bulky cobal...
