Il Foro Bonaparte: l'architettura della citta'

La ricerca ha per oggetto il progetto del Foro Bonaparte a Milano redatto da Giovanni Antonio Antolini a seguito del decreto del 23 giugno 1800 che stabiliva l’abbattimento delle mura del Castello Sforzesco. Si affronta il tema dell’architettura avendo come obiettivo una lettura critica di tale progetto servendosi dell’analisi compositiva come strumento in grado di stabilire i rapporti che intercorrono tra la città, l’architettura e il tipo. Attraverso lo studio del progetto urbano la ricerca conferma l’ipotesi per la quale la grande forma totalizzante, perentoria e assoluta è capace di mutare la struttura urbana, offrendo un nuovo modello con cui rinnovare la città. L’ambizione di Antolini di veder realizzata l’opera è destinata a svanire nell’arco di pochi anni, ma il progetto per il Foro Bonaparte continuerà per lungo tempo ad evocare la sua idea innovativa fino ai giorni nostri. Sebbene l’opera sia destinata a rimanere un’architettura solo disegnata, le varie pubblicazioni continuano a circolare nelle accademie prima e nelle università successivamente, costituendo un importante patrimonio di studio e di ricerca per generazioni di architetti, fino alla riscoperta avvenuta con Aldo Rossi e Manfredo Tafuri negli anni sessanta del secolo scorso. Dalle lezioni formulate nelle architetture del passato è possibile avanzare nuove ipotesi e alimentare riflessioni e dibattiti sul ruolo dell’architettura nella città contemporanea. La ricerca si occupa del progetto d’architettura per offrire un ulteriore contributo al tema, attraverso una lettura di carattere compositivo, supportata da una serie di schemi e disegni di studio necessari per completare il testo e per verificare i concetti esposti. Dopo aver raccolto, catalogato ed analizzato il materiale iconografico relativo al progetto per il Foro Bonaparte si è scelto di basare il ridisegno sulla raccolta di disegni conservati presso la Biblioteca Nazionale di Francia.

Reproduction and artificial restocking of Acipenser naccarii (Bonaparte, 1836). Genetic and physiological characterization through microsatellite markers and radioimmunoassay of sexual steroids

The Adriatic sturgeon, Acipenser naccarii (Bonaparte, 1836), is a highly threatened species due to human activities, particularly overfishing and habitat destruction. Its peculiar ecology and biology (restricted areal and anadromy) makes this species particularly vulnerable. In March 2010 the IUCN has identified the Adriatic sturgeon as a critically endangered species according to the Red List of Threatened Species. Due to its rapid decline, starting from the 80s, at present there is no evidence of natural reproduction in wild environment, which makes the Adriatic sturgeon dependenton captive breeding programs that need to be improved in order to be effective for the survival of the species. For this purpose this study aims to characterize artificial restocking population of Adriatic sturgeon, with both genetic and physiological analysis in order to establish an efficient restocking program for future reproductions. The research is structured on two levels: First genetically, by analyzing 9 microsatellite loci. This gives information relatively about parent allocation and kinship between individuals that were sampled for this study. Hence to predict which reproduction events are the most optimal in terms of incrementing genetic diversity, by the estimation of multilocus pairwise band sharing coefficients. Second step, physiological analysis: testosterone (T) concentration levels in each individual were measured for sexing, without sacrificing the lives of the animals with the use of an invasive examination of the gonads. The combination of interdisciplinary analysis is important to obtain an overall picture in order to indicate the main broodstock participating in reproduction events and future optimal potential participants, in order to ensure a valid management for restocking program and their monitoring.

Carotid plaque in Alzheimer caregivers and the role of sympathoadrenal arousal

To test the hypothesis that those who provide care for a spouse diagnosed with Alzheimer's disease would have increased prevalence of carotid artery plaque compared with noncaregiving controls and that prolonged sympathoadrenal arousal to acute stress would relate to this difference. Providing care for a spouse with Alzheimer's disease has been associated with an increased risk of coronary heart disease, potentially due to the impact of caregiving stress on the atherosclerotic disease process.

Leisure activities, caregiving demands and catecholamine levels in dementia caregivers

This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n = 107; mean age = 73.95 ± 8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β = 0.41; p = 0.005) and EPI (β = 0.44; p = 0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β = -0.08; p = 0.57) or EPI (β = 0.23; p = 0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers.

Cardiometabolic effects in caregivers of nursing home placement and death of their spouse with Alzheimer's disease

To test the hypothesis that cardiometabolic risk is attenuated when caregivers are relieved of caregiving stress when the caregiving recipient transitions out of the home.

Effect of Alzheimer Caregiving on Circulating Levels of C-Reactive Protein and Other Biomarkers Relevant to Cardiovascular Disease Risk: A Longitudinal Study

Providing care to a spouse with Alzheimer's disease (AD) may contribute to cardiovascular disease (CVD). The acute phase reactant C-reactive protein (CRP) is a well-established biomarker of an increased CVD risk.

Sleep in spousal Alzheimer caregivers: a longitudinal study with a focus on the effects of major patient transitions on sleep

Findings on sleep disturbances in family dementia caregivers are conflicting. We studied the longitudinal effects of dementia caregiving and major transitions in the caregiving situation on caregivers' sleep and the effect of moderating variables.

Relationship between chronic stress and carotid intima-media thickness (IMT) in elderly Alzheimer's disease caregivers

The stress associated with providing care for a spouse diagnosed with Alzheimer's disease can have adverse effects on cardiovascular health. One potential explanation is that chronic caregiving stress may contribute to the development of atherosclerosis. The purpose of this study was to determine whether the duration that one has provided care is associated with the degree of atherosclerotic burden, as measured by carotid artery intima-media thickness (IMT). One hundred and ten Alzheimer caregivers [mean age 74 ± 8 (SD) years, 69% female] underwent in-home assessment of carotid artery IMT via B-mode ultrasonography. Data regarding medical history, blood pressure, and multiple indicators of caregiving stress were also collected. Multiple regression indicated that duration of care was positively associated with IMT measured in the internal/bifurcation segments of the carotid artery (β = 0.202, p = 0.044) independent of risk factors such as age, gender, body mass index, smoking history, sleep quality, hypertension status, and caregiving stressors. Duration of care was positively associated with IMT in the common carotid artery, but the relationship was not significant. These findings provide more evidence of the link between chronic caregiving stress and cardiovascular disease and indicate that enduring the experience of caregiving over a period of years might be associated with atherosclerotic burden.

A Longitudinal Analysis of the Relations Among Stress, Depressive Symptoms, Leisure Satisfaction, and Endothelial Function in Caregivers

Stress and depressive symptoms have been associated with impaired endothelial function as measured by brachial artery flow-mediated dilation (FMD), possibly through repeated and heightened activation of the sympathetic nervous system. Behavioral correlates of depression, such as satisfaction with leisure activities (i.e., leisure satisfaction), may also be associated with endothelial function via their association with depressive symptoms. This study examined the longitudinal associations between stress, depressive symptoms, leisure satisfaction, and endothelial function as measured by FMD.

Effect of chronic dementia caregiving and major transitions in the caregiving situation on kidney function: a longitudinal study

To estimate the glomerular filtration rate (GFR) in relation to the chronic stress of dementia caregiving and major transitions in the caregiving situation.
