Effect of Delayed Refrigeration on the Microbial Carcass Contamination of Wild Boars (Sus scrofa).

The immediate refrigeration of meat after slaughter is a key issue for the proper storage and aging of meat. The industry standard cold chain relies on low temperatures and ventilation to lower the internal carcass temperature to 0-4 °C within the first 48 h, i.e., within four times the so-called semi-cooling time. On the other hand, for games, once bled and eviscerated, the carcass must be sent to a point where it can be sectioned or kept on air for maturation at refrigeration temperature. The precautions to observe are few and simple but essential: protect the meat and start the cooling process quickly. After preparing the animal (bleeding and evisceration), it may be necessary to face a period of transport that is sometimes long and not very easy; while small animals can be easily transported in a backpack, larger ones must necessarily be carried by several people or sometimes dragged to the vehicle capable of transporting them. It is obvious that a wild boar opened from the jaws to the pelvis and dragged for hundreds of meters will tend to be contaminated, although these contaminations are to be considered secondary for the preservation of the meat, compared to contamination by the intestinal contents. In an attempt to investigate the effect of delayed refrigeration on wild boar carcass contamination, the aim of this work was to determine a correlation between several hunting and logistic parameters (age, sex, animal weight, shooting distance, number of shots, weather and temperature and time from shot to refrigeration and to analysis) and bacterial contamination of the carcass. The correlation coefficient, r, was found to be 0.038 for the eviscerated body weight (p < 0.05), 0.091 for the external temperature on the day of hunting (p < 0.05), 0.027 for the time from shot to refrigeration (p = 0.081), 0.038 for the time from refrigeration to analysis (p < 0.05) and 0.043 for the time from shot to analysis (p < 0.05). These results stand for a negative correlation between the bacterial population and eviscerated carcass weight and between the bacterial population and external temperature and for a positive correlation between the time from shot to analysis and from refrigeration to analysis. No association was demonstrated between the bacterial population and the time from shot to refrigeration.

Nutritional Quality of Preparations Based on Döner Kebab Sold in Two Towns of Veneto Region, Italy: Preliminary Results.

The sampling activity for this study was performed between September and October 2012. It involved seven shops in Verona, eleven in Vicenza and two in its province (Bassano del Grappa), northern Italy. The scope was to measure the values of energy and nutritional components and to identify the profile of fatty acids in a serving of ready to eat Döner Kebab. The samples were collected according to the usual proportions of this preparation, keeping all the components (bread, meat, vegetables and sauces) separated in different bags. In the laboratory, each component was weighed and, after pooling, processed for the analytical determination of humidity, crude protein, lipid content and fatty acid profile, ashes, sodium (salt), carbohydrate, collagen (measured only in meat) and fibre. The results showed a highly standardized recipe, while the comparison between the two towns showed a significant difference in carbohydrate concentration (mainly due to the quantity of bread used). By observing data on the serving sizes sampled (274 to 618 g) and the nutritional values obtained, Döner Kebab can be seen as a ready to eat dish providing much energy: on average a serving size covers 45 and 36% of the recommended daily intake of energy, 95.7 and 82.1% of protein, 42.5 and 33.4% of saturated fatty acids for females and males, respectively, and 85.5% of salt regardless of gender. Döner Kebab can be considered as an occasional substitute to one of the two main meals of the day.

Detection of HER2 amplification using the SISH technique in breast, colon, prostate, lung and ovarian carcinoma.

HER2 gene amplification was explored using the silver stain hybridization in situ (SISH) technique in colon, prostate, lung, ovarian and breast carcinomas. Clinical pathological features and immunohistochemical (IHC) expression were evaluated for HER2 in 225 carcinomas. All cases were subjected to SISH investigation. Statistical analysis revealed an association between HER2 protein expression and gene amplification in breast carcinoma. 14% of colon carcinomas (5 IHC score 0, 1 score 1+ and 1 score 2+), 2% of prostate carcinoma (IHC 2+), 4% of lung carcinomas (IHC 2+) and 16% ovarian carcinomas (IHC 3+) revealed gene amplification. SISH is an advantageous technique for the detection of gene amplification. The use of the SISH technique in breast carcinoma may be an alternative to other in situ hybridization (ISH) techniques however more detailed studies seem necessary to detect HER2 gene amplification in other human malignancies.

Immunohistochemical expression and prognostic significance of fatty acid synthase in pancreatic carcinoma.

BACKGROUND: The aim of this study was to evaluate immunohistochemical markers in pancreatic cancer and to determine the association of their expression with clinicopathological features and prognosis. PATIENTS AND METHODS: Thirty pancreatic adenocarcinoma patients were followed-up for an average period of 5 years. FAS, bcl-2, p53 and Ki-67 expression were detected immunohistochemically to determine their prognostic value. RESULTS: FAS was statistically associated with p53 (p = 0.002), Ki-67 (p = 0.003), higher histological grade (p = 0.001 and recurrence and overall survival (p = 0.001). CONCLUSION: The newly found overexpression of FAS in highly aggressive pancreatic carcinomas may help us stratify patients into different prognostic groups and indicate new therapeutic strategies.
