A high chlorinated alumina catalyst obtained by treating Pt/γ-Al2O3 (0.25 wt. % Pt) samples with two mixtures of CCl4/N2 and CCl4/N2/H2 was tested for the hydroisomerization of C6 alkane. The conversion of n-hexane feed was diluted with hydrogen performed with different H2/HC ratios at various temperatures, liquid hourly space velocities (LHSVs) and 3MPa total pressure. The catalyst introduced ...

The cuticle, a hydrophobic protective layer on the aerial parts of terrestrial plants, functions as a versatile defensive barrier to various biotic and abiotic stresses and also regulates water flow from the external environment. A biopolyester (cutin) and long-chain fatty acids (waxes) form the principal structural framework of the cuticle; the functional integrity of the cuticular layer depen...

Abstract Background and Aims The classification of renal diseases is dependent on the evaluation kidney biopsies using light microscopy techniques. Ultrastructural details (e.g. podocyte foot processes, amyloid fibrils, Fabri's intracellular inclusions) need transmission electron (TEM) which has high costs, requires specialized personnel time consuming. Therefore, alternative techniques are hig...

In embryological work using vital dyes it is highly desirable to be able to study the distribution of the dyes in fixed material, whether examined in toto or after embedding in paraffin and serial sectioning. However, both fixation and dehydration present problems for the preservation of colour in vitally stained cells. Some fixatives preserve some dyes but, so far as I am aware, none will pres...

A problem associated with use of the polymerase chain reaction to amplify specific DNA fragments from formalin fixed, paraffin wax embedded tissues is the not infrequent failure of amplification. One possible reason for this could be the presence of inhibitor(s), which interfere with the activity of the reaction. It has been shown that such inhibitor(s) exist when amplifying the human fl globin...

Owing to their promising catalytic and adsorptive properties, microporous materials, often referred to as molecular sieves or open-framework materials, have attracted more and more attention in different research fields. Among them, microporous aluminiophosphate molecular sieves (designated AlPO4-n) have been extensively studied by many authors, owing to their wonderfully complex structures and...

As long as the molecular complexity increases, the number of chemical transformations will increase in parallel, becoming a highly demanding synthetic process in terms of time and resources. Since the loss of material after each purification step will also dramatically reduce the overall efficiency of a synthetic process, the conversion of such transformation into a practical and efficient proc...

Background and Study Aim: Recently, immunohistochemistry has shown numerous IgG4-positive plasma cells in a subset of Hashimoto’s thyroiditis (HT), and this type of HT (IgG4 HT) appears to be a subtype of IgG4-related sclerosing disease. However, little is known about the distribution pattern of plasma cells in IgG4 thyroiditis. To clarify the distribution pattern of IgG4-positive plasma cells,...
