Genetic variability of Akhal-Teke horses bred in Italy

Background. The Akhal-Teke horse (AKH) is native of the modern Turkmenistan area. It was introduced in Italy from 1991 to 2000 mainly as an endurance horse. This paper characterizes the genetic variability of the whole Italian AKH horse population and evaluates their inbreeding level by analyzing microsatellite markers and mitochondrial D-Loop sequences. Methods. Seventeen microsatellite marker loci were genotyped on 95 DNA samples from almost all the AKH horses bred in Italy in the last 20 years. Standard genetic variability measures (Ho, He, FIS) were compared against the same variables published on other eight AKH populations. In addition, 397 bp of mtDNA D-loop region were sequenced on a sub-group of 22 unrelated AKH out of the 95 sampled ones, and on 11 unrelated Arab horses. The haplotypes identified in the Italian population were aligned to sequences ofAKH(56), Arab (five), Caspian Pony (13), Przewalskii (two) and Barb (15) horses available in GenBank. The Median Joining Network (MJN), Principal Component Analysis (PCA) and Neighbor-joining (NJ) tree were calculated on the total 126 sequences. Results. Nucleic markers showed a high degree of polymorphism (Ho D 0.642; He D 0.649) and a low inbreeding level (FIS D 0.016) in Italian horses, compared to other AKH populations (ranged from 0.103 AKH from Estonia to 0.114 AKH from Czech Republic). High variability was also recorded in the D-Loop region. 11 haplotypes were identified with haplotype diversity (hd), nucleotide diversity () and average number of nucleotide differences (k) of 0.938, 0.021 and 6.448, respectively. When all the 126 D-Loop sequences were compared, 51 haplotypes were found, and four were here found only in the Italian AKH horses. The 51 haplotypes were conformed to eight recognized mtDNA haplogroups (A, C, F, G, L, M, P and Q) and confirmed by MJN analysis, Italian horses being assigned to five haplogroups (A, C, G, L and M). Using a PCA approach to the same data, the total haplotypes were grouped into two clusters including A+C+M+P and G+F haplogroups, while L and Q haplogroups remained ungrouped. Finally, the NJ algorithm effectively discretizes only the L haplogroup. All the above data univocally indicate good genetic variability and accurate management of the Akhal-Teke population in Italy

De memória, trauma e ficção: um olhar sobre a narrativa de Bernardo Kucinski

Muitos são os contratempos e prejuízos humanos associados ao período da ditadura militar no Brasil. Os processos de enrijecimento de controle estatal, as estratégias de domínio político-cultural e as tentativas de apagamento da memória marcaram o cotidiano da sociedade durante os anos que envolveram o estado de exceção. Apesar dessa realidade, os relatos de tortura e de denúncia testemunham diferentes versões para os fatos e contêm o poder de ressignificação da memória, especialmente por meio da escrita literária. Este artigo visa a propor uma breve discussão sobre os temas memória e trauma na construção ficcional, a partir da análise de contos publicados na antologia Você vai voltar pra mim e outros contos, de Bernardo Kucinski (2014)

Mitochondrial DNA genetic diversity in six Italian donkey breeds (Equus asinus)

Donkeys have played an important role in agricultural land practices and in human historical periods of recent past and, still today, are used as a working power in several world areas. The objective of this study was to identify genetic variability in six Italian donkey breeds using mtDNA D-loop. Fifteen haplotypes, grouped in three haplogroups, were identified. The genetic indices were informative and showed a high population genetic variability. The results of AMOVA analyses based on geographic structuring of Italian populations highlighted that the majority of the observed variance is due to differences among samples within breeds. Comparison among Italian haplotypes and mtDNA D-loop sequences belonging to European domestic and Ethiopian donkeys and wild asses, clearly define two clades referred to Nubian lineage. The results can be useful to complement safeguard planes for donkey breeds that are considered to extinction endangered

Genetic screening of the inherited Ichtyosis causative mutation in Chianina cattle

Inherited Ichthyosis is a genetic disorder reported in both humans and animals, including bovines. Two inherited forms were reported in cattle and both are transmitted in an autosomal recessive manner: Ichthyosis Fetalis (IF) and Ichthyosis Congenita (IC). A causative mutation of IF in Chianina cattle was recently indentified in the ABC12 gene. This work reports the first genetic screening using this recently available genetic test on Chianina cattle. Tests were performed on both the population of farm breeding selected young bulls (131 samples randomly chosen) and high breeding value sires (16 samples). Results confirm a low total prevalence of carriers in the selected sire population (2/131; 1.5%) and the presence of the disease allele among the high value selected sires (1/16; 6.3%). This result strengthens the importance to continue the genetic screening program, particularly in performance tested bulls approved for use in AI or natural servic
