Preparation, Characterization and Adsorption Potential of Grainy Halloysite-CNT Composites for Anthracene Removal from Aqueous Solution.

Grainy Hal-CNT composites were prepared from powder halloysite nanoclay (Hal) and carbon nanotubes (CNTs). The effect of the amount and type of CNTs, as well as calcination temperature on morphology and properties of Hal-CNT composites and their adsorption capacity of anthracene (ANT), were studied. The surface topography of granules was heterogenous, with cracks and channels created during granulation of powder clay and CNTs.

Kinetics and equilibrium of the sorption of bisphenol A by carbon nanotubes from wastewater.

The aim of this study was to determine the sorption potential of carbon nanotubes (CNTs) to bisphenol A (BPA) contained in synthetic wastewater whose composition corresponds to biologically treated effluents. These nanotubes differed in their outer diameter, the number of graphene layers and the presence of modifying functional groups. Based on the nitrogen adsorption-desorption isotherms, mensuration of the specific surface area and pore size distribution was undertaken.

[The influence of selected prognostic factors on the results of combined treatment of invasive carcinoma of the cervix on stage IB and stage IIA].

This is a retrospective analysis of 180 patients treated by combination of radical surgery and radiotherapy for invasive carcinoma of the cervix in stage IB and IIA. The influence of the following prognostic factors on the survival has been evaluated: the presence of pelvic lymph node metastases, histopathology of the tumor, the size of the primary tumor, presence of vascular space invasion and surgical margines. Nodal status has proved to be the most important prognostic factor: 91% of patients without pelvic lymph node metastases survived 5 years, 57% with up to two metastases and 36% with three and more metastases to the pelvic nodes.

[Carcinoma of the fallopian tube. Clinical analysis of 40 cases].

The results of clinical analysis of 40 cases of primary carcinoma of the fallopian tube are presented. All patients were treated with surgery and post operative external beam irradiation. Overall 5 years survival was 37% and symptom free survival 21%.

Spontaneous corneal neovascularization in nude mice. Local imbalance between angiogenic and anti-angiogenic factors.

Purpose: The present study considered the hypothesis that spontaneous neovascularization of the cornea of nude mice results from a local imbalance between angiogenic and anti-angiogenic factors.

Methods: The presence of angiogenic and anti-angiogenic factors was revealed by exchanging orthotopic corneal allografts between nude BALB/c mice and normal (hirsute) euthymic BALB/c mice and observing the presence, intensity, and degree of corneal neovascularization before and after grafting.

Results: Avascular corneal grafts from normal BALB/c donors resisted neovascularization after grafting to spontaneously vascularized graft beds in nude mice.
