Determination and quantification of PCBs, POCs and PAHs in Thunnus thynnus from the Straits of Messina (Italy).

This data set is composed to assess the accumulation of persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) dioxin like (DL) and not dioxin like (NDL), organochlorine pesticides (POCs) and polycyclic aromatic hydrocarbons (PAHs) in Thunnus thynnus and to elucidate the suitability of this species as a bioindicator for monitoring contaminations of these compounds in the marine ecosystems of the Straits of Messina. This investigation was conducted on liver samples of 14 T. thynnus collected during April 2015.

ProTaper and WaveOne systems three-dimensional comparison of device parameters after the shaping technique. A micro-CT study on simulated root canals.

Aim: The aim of this study is to highlights possible differences in the volume of shaping and canal surface area after the using of common endodontic devices ProTaper Universal and WaveOne systems.

Methods: Forty ISO 15, 0.02 taper, S-shaped endo-training Blocks (Dentsply, Maillefer) were assigned in two groups (n = 20 for each group).

Pattern of nodal involvement in papillary thyroid cancer: a challenge of quantitative analysis.

Introduction: Backgrounds of this study were to examine and analyse the relationship among the number of lymph nodes with metastases harvested in central and lateral compartments, the characteristics of tumours and patients, and the recurrences rate.

Methods: A retrospective review of 118 patients treated for a papillary thyroid cancer and underwent to neck dissection, including in all cases both central and lateral compartment, was realised. A quantitative analysis, on this homogeneous cohort of patients, was performed to hypothesize the minimum number of cervical lymph nodes to be necessarily excised in order to obtain an adequate management of these patients.

The "different face" of esophageal cancer: cutaneous manifestation of visceral malignancies.

Squamous cell carcinoma is the most common type of neoplasm of the esophagus with global incidence. Its early symptoms are often nonspecific as the disease could be detected only when metastases in various organs are already presented. Esophageal metastases present an extremely small part from all cutaneous metastases as the real incidence of cutaneous metastases due to cancer of the esophagus account for 0.

Embedded systems for supporting computer accessibility.

Nowadays, customized AT software solutions allow their users to interact with various kinds of computer systems. Such tools are generally available on personal devices (e.g.

Emotional reactivity in referred youth with disruptive behavior disorders: the role of the callous-unemotional traits.

Deficits in emotional reactivity are frequently reported in Disruptive Behavior Disorders (DBDs). A deficit in prosocial emotions, namely the callous unemotional traits (CU), may be a mediator of emotional reactivity. Our aim is to investigate subjective emotional reactivity towards visual stimuli with different affective valence in youths with DBDs and healthy controls.

Potential role of growth factors in ovarian cancer.

As with many other tumors, the origin and development of ovarian cancer is constituted by several molecular mechanisms, many of which are still unknown. Furthermore, data in the literature are incomplete and often contradictory, and they are mainly founded on results obtained on cell lines and not on observations based on the in vivo study of ovarian cancer. Despite this situation, the study of control mechanisms of proliferation and differentiation in normal ovarian functioning has enabled clinicians to identify certain growth factors and oncogenes which seem to have an important role in the neoplastic transformation of ovarian tissue.

Immunocytochemical detection of lactoferrin in human gastric carcinomas and adenomas.

In gastric carcinomas, including 20 cases of intestinal type and 10 cases of diffuse type, in adenomas with mild to severe dysplasia (20 cases), and in hyperplastic polyps (10 cases), the presence of lactoferrin was investigated by immunohistochemistry. Incomplete or complete intestinal metaplasia or both and normal gastric mucosa were also tested. Preoperative hematocrit and serum iron levels (18 patients) were recorded.
