Ionizing radiation and stress: the analysis of the medical ray technician.

Background: The present study aims to analyzing the relation between the work-related distress with the exposition to ionizing radiations in the radiology technicians, in the hospital environment.

Materials And Methods: Our present study has been conducted on a group of 36 sanitary technicians (14 women and 22 man, with an average age of 48±10,1 years) working in the Hospital Radiology Pavilion; 28 of them were less-exposed to radio-active emissions (B Category) and 8 were more exposed to radio-active emissions (A Category). The HSE questionnaire has been administered to all the 36 sanitary technicians.

[Meta analysis indices of genotoxic damage in urban pollution exposed workers].

Objectives: The aim of this study is to examine if urban pollution can modify indices of genotoxic damage.

Methods: Research of articles inherent in the evaluation of these alterations. Differents categories of exposed workers are included in the study (cases, in number of 7287) and compaired with no exposed workers (controls, in number of 8054).

TRF2 controls telomeric nucleosome organization in a cell cycle phase-dependent manner.

Mammalian telomeres stabilize chromosome ends as a result of their assembly into a peculiar form of chromatin comprising a complex of non-histone proteins named shelterin. TRF2, one of the shelterin components, binds to the duplex part of telomeric DNA and is essential to fold the telomeric chromatin into a protective cap. Although most of the human telomeric DNA is organized into tightly spaced nucleosomes, their role in telomere protection and how they interplay with telomere-specific factors in telomere organization is still unclear.

Tests for the evaluation of depression in the elderly: a systematic review.

The incidence of depression in the elderly has risen in recent years, with 30% of people over the age of 65 now reported to suffer from mood disorders. There are a number of possible causes for this increase; moreover, as the symptoms of depression in the elderly are often difficult to identify and interpret, a diagnosis of depression in the elderly may be difficult to make, particularly when other concomitant pathologies mask the signs and symptoms of this disease. There is thus a need to standardize the various self-rating and hetero-evaluation scales used to differentiate between normal and depressed subjects.
