Background: Postpartum hemorrhage (PPH) is the leading cause of maternal death worldwide. The World Maternal Antifibrinolytic trial showed that antifibrinolytic tranexamic acid (TXA) reduces PPH deaths. Maternal anemia increases the risk of PPH.

Homebirth is legal and has been regulated by law in Hungary since 2012. Despite the obvious advantages of homebirth, it has not yet been broadly accepted, due to various opinions related to safety and risks associated with giving birth outside of a hospital. Our study aimed at exploring both real maternal and feto-neonatal characteristics associated with Hungarian homebirths.

Vesicoureteric reflux (VUR) is defined as the retrograde passage of urine from the bladder into the upper parts of urinary system. The first symptoms may be seen in infancy, but may as well develop during entire life of the patient, in some patients being atypical. A quick diagnosis is of utmost importance since any delay in the treatment can cause many serious complications such as recurrent urinary tract infections (UTI), renal scarring development, hypertension and renal insufficiency.

Currently used clinicopathological parameters are insufficient for a reliable prediction of metastatic risk and disease-free survival (DFS) of patients with clear-cell renal cell carcinoma (ccRCC). To identify prognostic genes, the expression profiles of primary ccRCC obtained from patients with different DFS--eight synchronously, nine metachronously and seven not metastasized tumors--were determined by genome-wide expression analyses. Synchronously and metachronously metastasized primary ccRCC differed in the expression of 167 genes.

Purpose: AQP0, formerly known as MIP26, likely has multiple separate functions in the mammalian lens, including water transport, formation of thin junctions, and interactions with other lens components. Although mammalian genomes contain only one Aqp0 gene, the zebrafish genome contains two, Aqp0a and Aqp0b, and the putative multiple functions of the single mammalian protein may be divided between these two genes. The purpose of this study was to exploit this gene duplication and divergence to illuminate the multiple functions of AQP0 in the lens.
