Nuovo siero con vitamina C levogira stabilizzato con melatonina e resveratrolo. Prove di stabilità e uso clinico

2012

Nuovo siero con vitamina C levogira stabilizzato con melatonina e resveratrolo. Prove di stabilità e uso clinico Matteo Tutino, Giuseppe Morici, L. Cavarra, Francesco Nanfitò, D. Camacaro, Vittorio Calabrese. Università di Palermo, Dipartimento di Biomedicina sperimentale e neuroscienze cliniche - Università di Catania, Dipartimento Biochimica Clinica Fino ad ora è stato difficile utilizzare la vitamina C nelle preparazioni cosmetiche a causa della sua instabilità. L’acido ascorbico infatti si ossida velocemente in seguito all’esposizione alla luce, alla temperatura e all’aria. In questo lavoro viene riportata la capacità della melatonina e del resveratrolo a stabilizzare la vitamina C levo…

Contra la patologización intensiva en términos de derechos humanos: Activismo gordo en Argentina

2020

This work addresses the way in which Argentine Fat Activism has developed, in recent years, the demand for depathologization of fatness, taking elements from critical discourses on the health of fat people to frame them in a perspective typical of the Human Rights. First, the contemporary fat body is described in terms of stigma and discrimination, especially in the health field. Then, they refer to a series of critical positions on the pathologization and medicalization of fatness from the biomedical perspective, Fat Studies and Fat Activism. Lastly, a series of interventions that the Argentine activist collective Taller Hacer la Vista Gorda produced between 2017 and 2020 were considered, …

Does predation maintain eyespot plasticity in Bicyclus anynana?

2004

The butterfly Bicyclus anynana exhibits phenotypic plasticity involving the wet-season phenotype, which possesses marginal eyespots on the ventral surface of the wings, and the dry-season form, which lacks these eyespots. We examined the adaptive value of phenotypic plasticity of B. anynana in relation to the defence mechanisms of crypsis and deflection. We assessed the visibility differences between spotless and spotted butterflies against backgrounds of brown (dry season) or green (wet season) leaves. Spotless butterflies were highly cryptic and less predated by adult bird predators than were spotted ones when presented against brown leaf litter. However, the advantage of crypsis disappea…

Chromoendoscopy with indigocarmine improves the detection of adenomatous and nonadenomatous lesions in the colon.

2001

BACKGROUND AND STUDY AIMS Depressed early cancers and flat adenomas have a high potential for malignancy with possible infiltrating growth, despite the small size of the lesion. Japanese investigators have shown that early diagnosis and classification of these lesions is possible with the help of chromoendoscopy. The aim of this study, therefore, was to evaluate the usefulness of chromoendoscopy during routine colonoscopy. PATIENTS AND METHODS During routine colonoscopy, vital staining with indigocarmine solution (0.4 %, 1 - 10 ml) was performed on all visible lesions in 100 consecutive patients without visible inflammatory changes. If findings on macroscopic examination were unremarkable, …

Age-dependent shift-to-the-right in the localization of colorectal adenomas.

1987

The age-dependent prevalence and topographical distribution of colorectal adenomas was investigated in 1006 unselected autopsies (554 males and 452 females) in Mainz, FRG. In 200 out of 1006 autopsies (19.8%) a total of 498 adenomas of the large intestine were detected. The percentage of patients with adenomas increased continuously with age. Only 6% of all adenomas were localized in the caecum and 8% in the rectum, whereas all the other adenomas were distributed rather evenly throughout the ascending colon (23%), the transverse colon (25%), the descending colon (15%) and the sigmoid colon (23%). Analyzing the topographical distribution of adenomas for definite age groups (40-59, 60-69, 70-…

The perception of food products in adolescents, lay adults, and experts:A psychometric approach

2022

Almost 40% of global mortality is attributable to an unhealthy diet, and adolescents and young adults are particularly affected by growing obesity rates. How do (young) people conceptualize and judge the healthiness of foods and how are the judgments embedded in people’s mental representations of the food ecology? We asked respondents to rate a large range of common food products on a diverse set of characteristics and then applied the psychometric paradigm to identify the dimensions structuring people’s mental representations of the foods. Respondents were also asked to rate each food in terms of its healthiness, and we used the foods’ scores on the extracted dimensions to predict the heal…

Amplitude, Latency, and Peak Velocity in Accommodation and Disaccommodation Dynamics

2017

The aim of this work was to ascertain whether there are differences in amplitude, latency, and peak velocity of accommodation and disaccommodation responses when different analysis strategies are used to compute them, such as fitting different functions to the responses or for smoothing them prior to computing the parameters. Accommodation and disaccommodation responses from four subjects to pulse changes in demand were recorded by means of aberrometry. Three different strategies were followed to analyze such responses: fitting an exponential function to the experimental data; fitting a Boltzmann sigmoid function to the data; and smoothing the data. Amplitude, latency, and peak velocity of …

Delayed Coloanal Anastomosis for rectovaginal fistula after colorectal resection for deep endometriosis

2016

The deep infiltrating endometriosis, defined as a subperitoneal infiltration of endometrial implants of ≥ 5 mm involving not only the colorectal tract but also rectovaginal septum, vagina and bladder often requires a challenging surgery. Endometriosis nodes of the rectovaginal septum, if symptomatic, need a resection of the involved colorectal tract with colorectal or coloanal anastomosis. Unfortunately in these cases is not uncommon the possibility of a postoperative rectovaginal fistula (RVF), caused by the weakness of the septum that must be skeletonized to completely remove the endometriosis nodes. Here we present a case of anastomotic leakage with high RVF after colorectal resection an…

Testing the Cross-Cultural Robustness of the Minority Stress Model in Gay and Bisexual Men

2017

The study tests the cross-cultural robustness of the minority stress model using a most different systems approach. Data from Western European, Eastern European (including Russian), Indian, Philippine, and Thai gay and bisexual men was obtained online. The final sample consisted of N = 90,467 participants who reported their level of satisfaction with life, victimization, felt stigma, and internalized homonegativity, as well as their disclosure status and sociodemographic details. Stepwise linear regressions were conducted on reported levels of satisfaction with life. Higher levels of victimization, felt stigma, and internalized homonegativity predicted lower satisfaction with life in all gr…
