Chemical Pesticides and Human Health: The Urgent Need for a New Concept in Agriculture.

The industrialization of the agricultural sector has increased the chemical burden on natural ecosystems. Pesticides are agrochemicals used in agricultural lands, public health programs, and urban green areas in order to protect plants and humans from various diseases. However, due to their known ability to cause a large number of negative health and environmental effects, their side effects can be an important environmental health risk factor.

Cosmetics as endocrine disruptors: are they a health risk?

Exposure to chemicals from different sources in everyday life is widespread; one such source is the wide range of products listed under the title "cosmetics", including the different types of popular and widely-advertised sunscreens. Women are encouraged through advertising to buy into the myth of everlasting youth, and one of the most alarming consequences is in utero exposure to chemicals. The main route of exposure is the skin, but the main endpoint of exposure is endocrine disruption.

Sun lotion chemicals as endocrine disruptors.

Ultraviolet solar radiation is a well-known environmental health risk factor and the use of sun lotions is encouraged to achieve protection mainly from skin cancer. Sun lotions are cosmetic commercial products that combine active and inactive ingredients and many of these are associated with health problems, including allergic reactions and endocrine disorders. This review focuses on their ability to cause endocrine and reproductive impairments, with emphasis laid on the active ingredients (common and less common UV filters).

Fibroblast activation protein and its prognostic significance in correlation with vascular endothelial growth factor in pancreatic adenocarcinoma.

Fibroblast activation protein (FAP), a selective protein for tumor stromal fibroblasts, is expressed in >90% of human epithelial carcinomas. A characteristic feature of pancreatic cancer is an extensive fibrotic or desmoplastic reaction surrounding the primary tumor. The present study aimed to evaluate the expression levels of FAP and vascular endothelial growth factor (VEGF) and determine their correlation in pancreatic adenocarcinoma.

Prognostic value of COX-2, P53, and EZH-2 evaluated by quantitative image analysis in premalignant and malignant breast lesions.

Background: Cytological differential diagnosis of atypical hyperplasia and well differentiated breast carcinoma may be challenging, because sometimes there is an overlap between the cytomorphological features of these lesions. The aim of the study was to investigate COX-2, EZH-2, p53 expression in carcinomas and the gray zone of breast cytology categories of atypical hyperplastic lesions with regard to biological behavior of the tumor.

Methods: FNA speciments from 100 patients with breast hyperplastic lesions and cancer were investigated by immunocytochemistry and a quantitative analysis for COX-2, p53, and EZH-2.
