Consumer acceptance for sheep milk-based yogurt-Evidence from a large sample of Italian consumers.

Testing consumer acceptance for a new product, such as the sheep milk-based yogurt, provides a measure of its market success, thus it informs producers on the effectiveness of their decision to transform sheep milk into yogurt to increase their revenues. This work explores to what extent consumers accept sheep milk-based yogurt and tests the role of personal-related factors and product-related features on shaping its acceptance. The study collects data from a representative sample of Italian yogurt consumers, and data are then analyzed via a logistic regression. Results show that male, highly educated, and high-income consumers are more likely than others to accept sheep milk-based yogurt. Findings suggest that consumers' food neophobia and variety seeking traits play a pivotal role in affecting consumer acceptance. Lastly, interest in nutritional and health-related yogurt features increases the probability of accepting sheep milk-based yogurt. Thus, sheep milk-based yogurt should be targeted at high-end male consumers and those interested in nutritional and health-related aspects of yogurt. Informing consumers about the sheep milk yogurt properties may further increase its acceptance and curb food neophobia, which we found to be one of the main barriers for the product acceptance. Future studies will explore consumer acceptance by using a real product and taste experiments.

Emerging trends in European food, diets and food industry.

Understanding how an adequate food security may be determined, how nutritional intakes evolve over time and are influenced by global dynamics are few of the questions scholars are trying to answer. In addition, a great interest is devoted to the changes in consumers' preferences and expectations as well as to the analysis of food innovations and their impact on the global market. We review the recent and emerging trends in food supply chains of selected sectors (fruits and vegetables, meat, and seafood), and deepen on emerging trends in the food industry. By presenting the evidence provided by the literature and emphasizing the unresolved research questions, we offer a critical view of future directions that should be followed by research agenda.

Age-related mitochondrial lipoperoxidation in human skin.

Mitochondria were isolated from the epidermis of human subjects of different ages by a procedure that included pretreatment of the tissue with bacterial protease before homogenization. That epidermal mitochondria catalyze enzymatic lipid peroxidation in the presence of NADPH and chelated iron (ADP-Fe3+) is indicated by the production of malonaldehyde. The process does not appear to be influenced by age, and it is strongly enhanced in preparations containing a small amount of melanin.

Soft tissue sarcomas: research of prognostic factors and therapeutics scheme.

The Soft Tissue Sarcomas shows consisting mortality that grazes 50%. Commonly the histologic type, the largeness of the tumor and the degree of malignity, are considered prognostic factors influencing the survival of patients affected from such tumor. The aim of our study is to characterize the new prognostic factors influencing the local recidives and metastatic dissemination. We have analysed 17 possible clinical and histologic prognostic factors in 80 patients affected of soft tissue sarcomas. The results have dimonstrated that: the compartimentality and the cellular differentiation seem to be more influent to the insurgence of local recidives and metastasis; while the low malignity degree, the wide surgical margins and the histopatological characters of benignity can influense positively the survival.

Treatment of angiomas with sclerosing injection of hydroxypolyethoxydodecan.

The authors discuss the indications for hydroxypolyethoxydodecan in the sclerosing treatment of angiomas, with particular reference to cavernous, venous, and evolutive angiomas (ie, immature angiomas that fail to involute by eight to ten months). Moreover, the sclerosing agent may be employed, in connection with embolization and subsequent surgery, in arteriovenous angiomas with a relevant cutaneous-subcutaneous development. The authors have successfully used the "interstitial" sclerosing technique, according to Andrews' method. This technique involves interstitial injections to obtain the sclerosis of the thin threads of fibrous tissue stroma between the blood vessels. The sclerosing therapy may cause the complete regression of "low flow" angiomas or, at least, a partial reduction that simplifies the ensuing surgical excision. In the case of partial regression of the angioma obtained with the sclerosing therapy, the surgery of the remaining angioma causes a lesser degree of bleeding (especially in areas that do not particularly lend themselves to surgical exploration, ie, the oral cavity); an increased reliability in the radicality of the intervention (due also to the reduced size of the lesion); and better results from an aesthetic-functional point of view.

[Local malignancy potential of basal cell and prickle cell epithelioma]. / Il potenziale di malignità locale negli epiteliomi baso- e spinocellulari.

A series of over 300 cases of highly malignant basal and prickle-cell epitheliomas is presented as an illustration of the way in which due importance is not always given to forms that may well be deeply invasive, though these are only some of the epitheliomas that may be encountered. The particular nature of each formation is not always evident at first and may be the cause of its further progression. High malignancy is more common in cases of recurrence and poor management, so that ineffective attempts at treatment may be seen as a contributing factor. Of course, when treatment has been correct, failure and subsequent recurrence may point to primary "predisposition" to recur; this tendency cannot yet be detected in time or with precision. Local malignancy is often independent of the type of epithelioma involved. Indeed, it is more serious and difficult to combat in the case of basal cell forms on first recurrence and resistance to proper management, whereas in prickle-cell epithelioma, when distant metastasis is prevented, local invasiveness is frequently conquered by truly radical surgery.

[Environmental and occupational factors in skin carcinogenesis. Indications for therapy and prevention]. / Fattori ambientali e professionali nella cancerogenesi cutanea. Indicazioni di terapia e prevenzione.

The authors review the environmental and occupational factors in cutaneous cancerogenesis, group them according to their characteristics, and in particular distinguish between factors of physical and chemical nature. The authors also discuss the influence of predisposing factors related to the somatic makeup (xeroderma pigmentosus) and to work environment. Particular emphasis is given to skin precancerous and therefore to the importance of a mass screening and an effective health education. The authors illustrate the disorder with their clinical pictures.

[Therapeutic indications for immature angioma in the early infancy]. / Indicazioni terapeutiche nell'angioma immaturo della prima infanzia

Angiomas are classified briefly and their main features are described. Attention is then directed to the most frequent type: immature angioma. Its main feature is a parenchymatous or soft-elastic consistency; this is important for diagnosis. Little swelling is noted during crying, laughing and with the patient in an inclined position. These angiomas are typical of early infancy and usually regress spontaneously with visible sequelae, as in 70% of the reported series. Treatment should thus be avoided, since it is often useless and may even be damaging. Exceptions include cases where further growth is noted during monthly or bimonthly controls, or where clinically ascertainable cavernomas are formed. Reference is made to the possibility of treatment with triamcinolone, though this is viewed more as a test of the possibility of regression.

The integration of vascular surgical techniques with oncological surgical protocols in the treatment of soft tissue sarcomas of the limbs.

Soft tissue tumors, involving the vascular bundle, require a particular surgical approach: oncological and vascular surgical techniques must be integrated in order to perform a limb-saving surgery with adequate margins. Thirty-six soft tissue sarcomas of the thigh and popliteal region were treated from June 1999 to September 2002. Nineteen cases involving the vascular bundle were analysed and placed in two groups according to imaging and clinical information: Group A, 14 patients, with tumors close to femoral vessels without adventitial infiltration, and Group B, 5 patients, with vascular infiltration. Group A was treated with vascular blunt dissection performing adventitial excision. Group B was treated with vascular "en-bloc" resection and reconstruction. Imaging and clinical information together with surgical techniques, strategies and complications were analysed in order to plan the surgical approach in neoplastic vascular bundle involvement.

Duplication of the glans penis manifested at puberty.

We report the case of a complete duplication of the glans, with prepuce and a blind end urethra just proximal to the dorsal aspect of the balanopreputial fold. The malformation was not evident at birth and during childhood, and became manifest only at puberty, with the growth of the external genitalia. It was not associated with other urinary malformations. Surgical excision was easy and uneventful.

Combined radiological and surgical treatment of arteriovenous malformations of the head and neck.

Arteriovenous malformations (AVMs) are high-flow lesions. More than 50% of all AVMs are located in the head and neck region. They represent a therapeutic challenge because of their hemodynamic characteristics and their modality of growth. AVMs have a tendency to recur and often require radical resection, making surgical ablation and reconstruction difficult. AVMs require angiography not only for diagnostic purposes but as an initial therapeutic step in the form of embolization. Surgical ablation, which follows a few days after embolization, is facilitated by the reduction in vascularity and shrinkage of the lesion, both of which are afforded by the embolization. These benefits allow for less blood loss at the time of ablation, and less extensive resection. The authors report their experience with 16 patients with extracranial AVMs of the head and neck examined over the last decade.

Steroid hormone receptors in female breast angiosarcomas.

Breast angiosarcoma is an extremely rare neoplasm usually affecting premenopausal women. Previous reports suggest that it is hormone-dependent. A case of primary breast angiosarcoma in a 16-year-old patient is presented in which the presence of estradiol, progesterone, and testosterone receptors was investigated. The histological findings initially revealed a simple angioma, but four months later the histological picture had completely changed, showing an angiosarcoma. Our data indicate a lack of receptors for steroid hormones in this tumor, which argues against the hypothesis presented in the literature.

Malignant tumors of the orbital region. Analysis of cases examined from 1986 to 1995.

OBJECTIVE: To present a retrospective study of 154 orbital tumors examined from 1986 to 1995. METHODS: We analyzed the clinical behavior and the degree of local malignity also in relationship with the particular anatomical characteristics of this site. RESULTS: In this are, it is not rare finding tumors with a scarce cutaneous extension but a deep involvement including the bone, or of recurrences after a previous insufficient treatment with an aggressive clinical course. CONCLUSION: The principles for the surgical approach are: exeresis as radical as possible, one-stage operation for tumoral resection and reconstruction, bringing of trophic tissue able to sustain any complementary treatment, easy and fast execution, and short clinical course.
