At slaughtering and post mortem characteristics on Traditional market ewes and Halal market ewes in Tuscany

Abstract Background The aim of this work was the comparison between the carcass and the meat ewes of the regional Traditional market and the Islamic religious (Halal) market. Methods Thirty and 20 at the end of career traditional market and Halal market ewes were slaughtered following the EC (European Council, 2009) animal welfare guidelines. Live weight of ewes was taken and dressing percentage of carcasses was calculated. On every carcass zoometric measurement and the evaluation trough the EU grid rules were performed. On the Musculus longissimus thoracis of 12 Traditional market carcasses and 11 Halal market carcasses the physical-chemical and nutritional analysis were performed. Consumer tests for liking meat ewe were performed in order to find consumer’s preference level for Traditional and Halal markets ewe meat. Considering as fixed factor the ewe meat market (Traditional and Halal), results were submitted to oneway Analysis of Variance (ANOVA) and to Principal Component Analysis (PCA). Results The Halal market ewes have shown lower dressing percentages (42.91 ± 0.82 vs 46.42 ± 0.69) and lower conformation score (4.5 ± 0.5 vs 7.8 ± 0.4). The Halal market meat showed higher cooking loss in oven (37.83 ± 1.20 vs 32.03 ± 1.15 %), lesser Chroma value (18.63 ± 0.70 vs 21.84 ± 0.67), and lesser Hue angle value (0.26 ± 0.02 vs 0.34 ± 0.02). This product had also lower fat percentage (4.2 ± 0.4 vs 7.09 ± 0.4). The traditional market meat had higher percentage in monounsatured fatty acids (MUFA) (43.84 ± 1.05 vs 38.22 ± 1.10), while the Halal market meat had higher percentage in ω3 poliunsatured fatty acids (PUFA) (5.04 ± 0.42 vs 3.60 ± 0.40). The consumer test showed as the ewe meat was appreciate by the consumers. Conclusions Both meat typologies have shown good nutritional characteristics. The traditional market meat had higher MUFA composition, and a better MUFA/satured fatty acids (SFA) ratio, while the Halal market meat had higher PUFA composition. These results were also supported by the PCA. The consumers preferred the traditional market meat

Quality characteristics of the Musculus longissimus dorsi from Pecora dell’Amiata reared in Tuscany

Pecora dell’Amiata sheep is registered in the Regional population register of the autochthonous endangered sheep and goat breeds, and it is a double purpose breed (meat and milk). It derives from the mount Amiata area in Tuscany. In Tuscany the sheep meat consumption occurs in particular in Easter and in Christmas time. Because of the new markets, ewe meat has shown in the last years a consumption increase. In Italy, the more consumed ovine meat is the suckling lamb meat. In the last years, this kind of meat production and consumption decreased in Italy, but the ewe meat consumption has been slowly increased, because of the spread of typical regional food, and the new market needs.The trial was performed with ewes and lambs deriving from the local breed Pecora dell’Amiata. In this work, the Musculus longissimus dorsi (M. longissimus thoracis + lomborum) physical-chemical and nutritional characteristics of 23 ewes and 20 lambs were compared. The ewes of the trial were over 7 years old while the lambs were on average 80 days old. Ewe meat has shown lower drip loss (4.14 vs 2.71%) and lightness (L* 38.6 vs 45.3) values, and higher PH (6.15±0.07), shear force (8.4 vs 2.31 kg), fat content (5.9 vs 2.0%). The lamb meat lipids had higher polyunsaturated fatty acid content (PUFA: 14.58 vs 9.25%) and higher PUFA/Saturated Fatty Acids (SFA) ratio (0.31 vs 0.20). The PCA analysis identified two distinct groups regarding ewe and lamb meat respectively for the fatty acids composition and the health indices. Ewe meat showed dietetic and nutritional characteristics similar to that of lamb meat. These characteristics may allow in the future, to the ewe meat valorisation, now not appreciated by Tuscan and Italian market

Cell wall-associated alpha-glucan is instrumental for Mycobacterium tuberculosis to block CD1 molecule expression and disable the function of dendritic cell derived from infected monocyte.

Summary We previously described an escape mechanism exploited by Mycobacterium tuberculosis (Mtb) to prevent the generation of fully competent dendritic cells (DC). We have now tested the effect of isolated mycobacterial components on human monocyte dif- ferentiation into DC and demonstrated that cell wall (CW)-associated alpha-glucan induces monocytes to differentiate into DC (Glu-MoDC) with the same altered phenotype and functional behaviour of DC derived from Mtb-infected monocytes (Mt-MoDC). In fact, Glu- MoDC lack CD1 molecule expression, fail to upregu- late CD80 and produce IL-10 but not IL-12. We also showed that Glu-MoDC are not able to prime effector T cells or present lipid antigens to CD1-restricted T-cell clones. Thus, we propose a mechanism of Mtb- monocyte interaction mediated by CW-associated alpha-glucan, which allows the bacterium to evade both innate and acquired immune responses

Baseline haematological and biochemical reference values for healthy male adults from Mali

Introduction: Haematological reference values are very important for diagnostic orientation and treatment decision. The aim of this study was to establish haematological reference values for Malian healthy adults. Methods: A cross-sectional study including 161 male Malians aged between 19 and 54 years old was performed. Median and reference ranges were calculated for haematological and biochemical parameters. Parametric student's t-test was used to determine any statistically significant differences by age, smoker status, body mass index (BMI) and occupation. Ranges were further compared with those reported for other African, Afro-American and Caucasian populations. Results: Increased levels of MCV, MCH, PLT and EOS were found in younger Malians who had abnormal BMI and altered platelets parameters. Notably, significantly lower eosinophil and monocyte counts were observed in Malians compared to Europeans The smoking status did not seem to directly affect RIs. Conclusion: This is the first study to determine normal laboratory parameters in Malian adult males. Our results underscore the necessity of establishing region-specific clinical reference ranges that would allow clinicians and practitioners to manage laboratory tests, diagnosis and therapies. These data are useful not only for the management of patients in Mali, but also to support European and American clinicians in the health management of asylum seekers and migrants from Mali

Prevalence and Prognostic Role of IDH Mutations in Acute Myeloid Leukemia: Results of the GIMEMA AML1516 Protocol

IDH1/2 mutations are common in acute myeloid leukemia (AML) and represent a therapeutic target. The GIMEMA AML1516 observational protocol was designed to study the prevalence of IDH1/2 mutations and associations with clinico-biological parameters in a cohort of Italian AML patients. We analyzed a cohort of 284 AML consecutive patients at diagnosis, 139 females and 145 males, of a median age of 65 years (range: 19–86). Of these, 38 (14%) harbored IDH1 and 51 (18%) IDH2 mutations. IDH1/2 mutations were significantly associated with WHO PS >2 (p < 0.001) and non-complex karyotype (p = 0.021) when compared to IDH1/2-WT. Furthermore, patients with IDH1 mutations were more frequently NPM1-mutated (p = 0.007) and had a higher platelet count (p = 0.036). At relapse, IDH1/2 mutations were detected in 6 (25%) patients. As per the outcome, 60.5% of IDH1/2-mutated patients achieved complete remission; overall survival and event-free survival at 2 years were 44.5% and 36.1%, respectively: these rates were similar to IDH1/2-WT. In IDH1/2-mutated patients, high WBC proved to be an independent prognostic factor for survival. In conclusion, the GIMEMA AML1516 confirms that IDH1/2 mutations are frequently detected at diagnosis and underlines the importance of recognizing IDH1/2-mutated cases up-front to offer the most appropriate therapeutic strategy, given the availability of IDH1/2 inhibitors

Sofferenza tubulare in un paziente con recente trapianto di rene

Tubular disfunction in a patient with a recent kidney transplant.The case reports about a patient who underwenta kidney transplantation for chronic disease of unknown cause. The clinical course showed a delayed graft functionand acute tubular necrosis. Urine microscopy confirmed a tubular disfunction: presence of renal epithelial cells,cylindruria and crystals. The microscopy images showed brownish-colored crystals that, under polarized light,suggested a 2.8-dihydroxyadenine (DHA) urolithiasis, rare and underdiagnosed pathology, due to the deficiency ofadenine-phosphoribosyltransferase (APRT). The specific analysis, i.e. the determination of the enzyme activity onerythrocyte lysate, did not confirm our initial hypothesis, excluding de facto a DHA urolithiasis. Analysis of purine andpyrimidine profile confirmed the presence of a purine dysmetabolism. The patient was treated with allopurinol, whichimproved the clinical picture. This case underlines the need for more extensive studies of crystal and/or metabolicnephropathies before renal transplantation. The microscopy study was however useful to trigger investigations thathave then influenced the therapy and the clinical progress of the patient
