Strategy, communications and environment: A case study in the Italian energy and ceramics sector

Since the voluntary environmental reporting of companies started in the late eighties, there has been a profusion of literature describing why a company should report and what principles should be followed. This thesis takes a less prescriptive approach by investigating what explains the environmental communication in some Italian firms in the Energy and the Ceramic sectors. The research for these

Sperm DNA integrity in cancer patients : the effect of disease and treatment

As oncological treatment might impair the patients' fertility, male cancer patients are offered to cryopreserve semen prior to treatment. Impaired sperm DNA quality is associated with reduced fertility, and in case of assisted reproduction, sperm DNA integrity may have an impact on choice of method. Therefore, we have assessed sperm DNA integrity in cancer patients, comparing pre- and post-treatme

Functional importance of estrogen receptors in the periodontium.

The main functions of estrogen are associated with reproduction. However, estrogen has been shown to be of functional importance also in non-classic target organs. Previous studies, especially epidemiologic and clinical ones, have addressed estrogen's influence on periodontitis, suggesting that estrogen has a beneficial effect, but the biological mechanisms have not been identified. Estrogen exert

Nitric oxide-producing cells project from retinal grafts to the inner plexiform layer of the host retina

PURPOSE: Amacrine cells expressing nitric oxide synthase (NOS) are seen in normal retinas and retinal grafts to extend long processes, which can be followed for long distances. Taking advantage of the morphologic features of these cells, the present study examined whether graft-host connections involve cells capable of producing nitric oxide, a recognized retinal neuromodulatory compound.METHODS:

Maternal morbidity and mortality in in-vitro fertilization.

Pregnancies following in-vitro fertilization (IVF) are known to be at increased risk of a number of pregnancy- and delivery-related complications when compared with non-IVF pregnancies. Most of these complications seem to be due to underlying fertility problems. Ovarian stimulation carries a marked risk for two serious conditions - ovarian torsion and ovarian hyperstimulation syndrome - both of wh

Desmopressin in vitro effects on platelet function, monitored with Multiplate, ROTEM and Sonoclot.

Background and aims The vasopressin analogue desmopressin has demonstrated efficacy in decreasing bleeding time by increasing the circulating levels of coagulation factor VIII and von Willebrand factor, but also by direct effects on platelets. Previous studies have demonstrated contrasting results regarding the effect of desmopressin on platelets in vitro. The aim of this study was to investigate
