Mayer-Rokitansky-Küster-Hauser syndrome type II: a case report and literature review

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a genetic disease consisting of absent uterus and upper part of vagina, and is seen in women with a normal karyotype (46, XX). It is one of the rare diseases where the estimated prevalence is 1:5000. Most patients present with primary amenorrhea at a young age, with or without bone or kidney abnormalities. The associated psychological aspects of this disease often enforce the need for a prompt diagnosis and treatment. The preferred method for preoperative evaluation of these patients is magnetic resonance imaging (MRI).

Evolution of singlet structure functions from DGLAP equation at next-to-next-to-leading order at small-x

A semi-numerical solution to Dokshitzer- Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equations at leading order (LO), next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) in the small-x limit is presented. Here we have used Taylor series expansion method to solve the evolution equations and, t- and x-evolutions of the singlet structure functions have been obtained with such solution. We have also calculated t- and x-evolutions of deuteron structure functions F_2^d, and the results are compared with the E665 data and NMC data. The results are also compared to those obtained by the fit to F_2^d produced by the NNPDF collaboration based on the NMC and BCDMS data.Comment: 26 pages, 6 figure
