Treatment for Infertility in Laron Syndrome: A Case Report.

Laron syndrome is a rare, genetic, growth hormone insensitivity disorder caused by mutations in the growth hormone receptor gene. Affected patients have severe postnatal growth failure, characteristic facial features, and metabolic abnormalities, including severe obesity and metabolic syndrome. Women with Laron syndrome are usually subfertile, mainly due to obesity and metabolic dysregulation, and require treatment for their chronic reproductive dysfunction.

Symptomatic ovarian involvement as the initial presentation of primary mediastinal large b-cell lymphoma.

Primary mediastinal large B- cell lymphoma (PMLBCL) is a mature aggressive B-cell lymphoma which affects mainly young and middle-aged women. The majority of patients present with bulky mediastinal lymphadenopathy. Extranodal involvement is a rare phenomenon at disease presentation.

Fetal heterozygosity for both Hb G-Hsi-Tsou and beta thalassemia: A case report.

Introduction: This case report describes a fetus with compound heterozygosity for Hb G-Hsi-Tsou and beta thalassemia, diagnosed in a healthy pregnancy. To the best of our knowledge, this is the first documented case of compound heterozygosity and the woman is the second known case of heterozygosity for Hb G-Hsi-Tsou.

Case Presentation: A 34-year-old woman during her first pregnancy underwent hemoglobin electrophoresis which revealed heterozygosity for Hb G-Hsi-Tsou.

New Drugs and Interventional Strategies for the Management of Hypertension.

Essential hypertension is an important cause of cardiovascular morbidity and mortality worldwide with significant clinical and economic implications. The field of antihypertensive treatment already numbers numerous agents and classes of drugs. However, patients are still developing uncontrolled hypertension.

Purification, crystallization, X-ray diffraction analysis and phasing of an engineered single-chain PvuII restriction endonuclease.

The restriction endonuclease PvuII from Proteus vulgaris has been converted from its wild-type homodimeric form into the enzymatically active single-chain variant scPvuII by tandemly joining the two subunits through the peptide linker Gly-Ser-Gly-Gly. scPvuII, which is suitable for the development of programmed restriction endonucleases for highly specific DNA cleavage, was purified and crystallized. The crystals diffract to a resolution of 2.
