H19 and Igf2 are closely linked, reciprocally imprinted genes which lie on distal chromosome 7 in the mouse. Data suggests that common elements are used for expression and imprinting of both genes, and simple models have been proposed based on the presence of a single set of enhancers located downstream of H19. In this study we have investigated the H19 expression pattern from a 130 kb YAC tran...

A rapid and safe method of Yeast Artificial Chromosome (YAC) physical mapping by cosmid 'fingerprinting' is presented. YACs are subcloned into cosmids which are prepared without previous separation of cloned DNA from host DNA. Groups of overlapping clones are detected according to their restriction fragments size and intensity after hybridization with total human DNA. To test this approach, a c...

We previously identified two commonly deleted regions on chromosome bands 10q25-q26 in endometrial cancer: an 8-cM region and a 12-cM region. In the present study, we further studied the 8-cM region with 83 endometrial cancer specimens and 14 microsatellite markers and narrowed it down to a 1-cM region between D10S587 and D10S1723. This result was confirmed by two-color fluorescence in situ hyb...

Fragile X syndrome is the most frequent form of inherited mental retardation and is associated with a fragile site at Xq27.3. We identified human YAC clones that span fragile X site-induced translocation breakpoints coincident with the fragile X site. A gene (FMR-1) was identified within a four cosmid contig of YAC DNA that expresses a 4.8 kb message in human brain. Within a 7.4 kb EcoRI genomi...

Deletions involving the long arm of chromosome 11 (11q) have been recently found as recurrent chromosome aberrations in mantle cell lymphoma (MCL). In the current study, the incidence and molecular extent of 11q deletions were analyzed in a series of 81 MCL by fluorescence in situ hybridization with probes from a contiguous set of yeast artificial chromosomes (YACs). Loss of chromosome 11 mater...

Incontinentia pigmenti (IP) is an X-linked dominant disorder of neuroectodermal development. Based on the observation of six unrelated females with clinical features of nonfamilial IP with constitutional de novo reciprocal X;autosome translocations, a putative incontinentia pigmenti type 1 locus (IP1; MIM No. 308300) was localized to region Xp11.21. Using available regional DNA markers, we cons...

Young adult carers (YACs) are people aged 18–25 years who provide care to a relative is ill or has disability. France begins come the YAC issue. students were mentioned for first time in national policy document 2019. By interviewing 110 students, this review showed that more than 80% of them did not know what was. If aware status, they cannot self-identify as and seek support. During developme...

This paper shows the performance and scalability evaluation of different blockchain platform implementations. Hyperledger Iroha implementing YAC consensus, Sawtooth PoET algorithm, Fabric framework implementation. Performance assessment were done by varying sets parameters such as block size, transaction sending rate, network traffic distribution, size. was based on average latency, throughput,...
