Breast carcinoma and anaplastic gastric carcinoma with pleural metastases in patient after mastectomy 30 years ago

We describe a case of two simultaneous malignancies - anaplastic gastric carcinoma with pleural metastases and left breast carcinoma. These malignancies were recognized in 78-year old woman after right mastectomy performed 30 years ago. Additionaly, during diagnostic procedures rectal polypus found during colonoscopy occurred to be adenoma tubulovillosum. Her parents died from malignancies - mother from gastric cancer and father from pulmonary carcinoma. One should remember that there is always possibility of simultaneous development of more than one primary malignancies in one patient and neoplastic disease is an important cancer risk factor. This observation confirms the important role of genetic factors in the pathogenesis of malignant diseases

Breast Carcinoma and Anaplastic Gastric Carcinoma with Pleural Metastases in Patient after Mastectomy 30 Years Ago

We describe a case of two simultaneous malignancies–anaplastic gastric carcinoma with pleural metastases and left breast carcinoma. These malignancies were recognized in 78–year old woman after right mastectomy performed 30 years ago.

NOx photocatalytic degradation on gypsum plates modified by TiO2-N,C photocatalysts

In presented studies the photocatalytic decomposition of NOx on gypsum plates modified by TiO2-N,Cphotocatalysts were presented. The gypsum plates were obtained by addition of 10 or 20 wt.% of different types of titanium dioxide, such as: pure TiO2 and carbon and nitrogen co-modified TiO2 (TiO2-N,C) to gypsum. TiO2-N,C photocatalysts were obtained by heating up the starting TiO2 (Grupa Azoty Zakłady Chemiczne Police S.A) in the atmosphere of ammonia and carbon at the temperature: 100, 300 i 600ºC. Photocatalyst were characterized by FTIR/DRS, UVVis/DR, BET and XRD methods. Moreover the compressive strength tests of modified gypsum were also done. Photocatalytic activity of gypsum plates was done during NOx decomposition. The highest photocatalytic activity has gypsum with 20 wt.% addition of TiO2-N,C obtained at 300ºC
