The construction and maintenance of road pavements entail detrimental impacts on the consumption of resources and damage to the natural environment but also make up an opportunity for the large-scale application of circular economy principles and innovative waste valorisation paths. The present study focuses on developing a comprehensive procedure to evaluate the technical and environmental sustainability of replacing high percentage of limestone aggregates with artificial aggregates from municipal solid waste incineration (MSWI) into hot or cold recycled asphalt mixtures for asphalt pavements. The technical feasibility of the designed mixtures was investigated in terms of the main physical and mechanical properties of both the raw materials and the asphalt mixtures with content of artificial aggregates or sand in the range 25-40 % by mass.

Some nutraceuticals known to promote hair growth are avoided during breast cancer therapy for fear of phytoestrogenic activity. However, not all botanical ingredients have similarities to estrogens, and in fact, no information exists as to the true interaction of these ingredients with tamoxifen.

This study aims to compare the life cycle impacts of several pavement solution alternatives involving, in the binder and base layers, some eco-designed, hot- and cold-produced asphalt mixtures made up of recycled aggregates in substitution for natural filler and commercial recycled polymer pellets for dry mixture modification. The first step focused on the technical and environmental compatibility assessment of the construction and demolition waste (CDW), jet grouting waste (JGW), fly ash (FA), and reclaimed asphalt pavement (RAP).

Use of CAM by healthy individuals and patients with medical conditions is rapidly increasing. For the majority of breast cancer patients, treatment plans involve 5-10 yrs of endocrine therapy, but hair loss/thinning is a common side effect.

One of the main goals is to calibrate Safety Performance Functions (SPFs) that can predict the frequency per year of injuries and fatalities on homogeneous road segments. It was found that on more than 2000km of study-road network that annual average daily traffic, lane width, curvature change rate, length, and vertical grade are important variables in explaining the severity of crashes.

Countermeasures are suggested to reduce the injury crash rate and include different awareness campaigns and structural measures on the segments of road.
Methods: An 8-year period was analyzed for which 5 years of crash information were used to calibrate and specify SPFs and the remaining 3 years were used to check the reliability of the equations.
Vitamin B5 and its derivatives are well known in personal care applications and are often used in wound healing and soothing compositions. However, little is known about the biochemical pathways involved. A better knowledge of these pathways would help to understand some of the mechanisms of action and suggest further applications.

Our aims were to examine the fit of all previously published factor models and then to explore unobserved population heterogeneity and identify salient latent classes. Two hundred thirty-nine patients with ICD-10 schizophrenia admitted to a random sample of all Italian public and private acute inpatient units during an index period were administered the BPRS-24.

Resurrection plant Haberlea rhodopensis develops molecules to survive drought stress. These molecules allow the plant to resurge from a desiccation state. We have extracted a specific fraction from the plant (Haberlea extract) and found it rich, among other molecules, of a caffeoyl phenylethanoid glycoside called myconoside, a molecule extremely abundant in the plant with a potential role in survival.

UV light induces multiple damages including protein oxidation on skin. Oxidized proteins if not degraded by the proteasome would eventually accumulate causing metabolic damage, elastosis and pigment formation such as lipofuscin. During ageing, the activity of the proteasome decreases dramatically together with enzymes that protect from oxidation and as a result oxidized proteins accumulate.

It is based on the assumption that the immune system contributes to the tissue damage and indeed its interaction with the muscle tissue after an initial endogenous damage can be described as a predator-prey system showing typical oscillations. In this article we investigate the dynamical properties of the system.

They identify the principles that have led to institutional transformation and to the replacement of the traditional psychiatric hospital with a complete organization of services across the Trieste territory. By defining the spirit presiding over these transformations, the authors describe the variety of services offered.

Objective: To describe: a) a self-report questionnaire of 34 item, developed by a Family Association of Psychiatric Patients in collaboration with two psychiatrists to evaluate by key-relative in a clinical practice the perceived quality of mental health services, the needs and family burden; b) the methodology of validation.
Methods: It has been studied (a) the Face Validity by two focus groups of 10 relatives for each group, (b) the concurrent validity of family burden items comparing the ABC with QPF, a widely used questionnaire, in 6 Italian mental health centres on a sample of key-relatives, (c) the discriminant validity comparing three different samples of key-relatives of patients with psychiatric illness, Alzheimer or cancer. The internal consistency of items for assessing relatives' opinions on the quality of care has been evaluated by Chronbach' s alpha.
Background: Legislation in 1978 led to the gradual replacement of mental hospitals in Italy with a full range of community-based services, including facilities for acute in-patient care.
Aims: To survey the main characteristics of Italian public and private in-patient facilities for acute psychiatric disorders.
Method: Structured interviews were conducted with each facility's head psychiatrist in all Italian regions, with the exception of Sicily.
A mouse model of staphylococcal sepsis was used to evaluate the efficacy of RNAIII-inhibiting peptide (RIP) combined with the cathelicidin BMAP-28. Preliminary in vitro studies showed that both peptides, alone or combined, were able to inhibit the lipoteichoic acid-induced production of tumor necrosis factor alpha and nitric oxide by RAW 264.7 cells.

Methods: An in vitro antibiotic susceptibility assay of Staphylococcus aureus biofilms using 96-well polystyrene tissue-culture plates was performed to test the effects of RNAIII-inhibiting peptide (RIP), ciprofloxacin, imipenem, and vancomycin. Efficacy studies were performed using a rat model of central venous catheter (CVC)-associated infection.
Staphylococcus aureus and Staphylococcus epidermidis associated with implantable medical devices, are often difficult to treat with conventional antimicrobials. Formation of a biofilm and subsequent production of toxins are two distinct mechanisms considered important in foreign body infections. Staphylococcal virulence is caused by a complex regulatory process, which involves cell-to-cell communication through the release and response to chemical signals in a process known as quorum sensing.
