Study on the Dye Removal from Aqueous Solutions by Graphene-Based Adsorbents.

In the current investigation, the removal efficiency regarding a cationic dye, methylene blue (MB), from three graphene-based materials was investigated. The materials' characterization process involved instrumental methods such as XRD, XPS, SEM, TEM, FTIR, and nitrogen adsorption at 77 K. The survey examined how various process factors influenced the ability of the studied materials to adsorb cationic dyes.

Facile Synthesized Cu-RGO and Ag-RGO Nanocomposites with Potential Biomedical Applications.

In the present study, we report on the facile prepared nanocomposites of reduced graphene oxide RGO with Cu and Ag. The synthesis was performed through an environmentally friendly and easy method by simultaneous reduction in solutions containing Cu or Ag and graphene oxide (GO) using zinc powder as a reducing agent in aqueous acidic media. The composites are characterized by powder X-ray diffraction, low-temperature nitrogen adsorption, X-ray photoelectron and FTIR and Raman spectroscopies, as well as Scanning and Transmission electron microscopies.

[Difficulties and biases of interpretation in cases of the trophoblast disease].

The trophoblastic disease (TD) is an unifying term for the nosologicunits: Mola hydatidosa, Mola hydatidosa invasivum, Chorionepithelioma. This kind of trophoblast pathology has geographic differences in the expression but the its overall incidence is not high. The clinicians often fail to consider the possibility of trophoblastic disease due to its low incidence rate.

[Results of preventive mammography before initiation of hormone replacement therapy].

Introduction: Breast cancer is the most common neoplasm among women, with a peak incidence at an age between 40 and 60. The contemporary guidelines for prophylactic breast cancer screening emphasize on performing an annual mammography, starting at the age of 40.

Objective: To analyze the results of the prophylactic mammography and clinical examination in a group of climacteric women before initiation of HRT.

[Endometriosis as an unexpected finding during laparoscopy on sterile women].

Objectives: Assessment of the laparoscopy as endoscope method at diagnosing as unsuspected finding at sterile women.

Materials And Methods: Studying is retrospective and includes 20 years period of time (1976-1996). We have examined the documentation of 912 patients on whom performed laparoscopy.
