Objective: To evaluate the prevalence of thrombocytopenia in neonates born to mothers with pregnancy induced hypertension (PIH) and identify the associated material and neonatal characteristics.
Methods: In the current, prospective study, platelet counts were assessed serially. Maternal and neonatal characteristic were recorded in pre-designed proforma. Primary outcome measures were thrombocytopenia defined as platelet count of <150,000/mm(3) and severe thrombocytopenia if counts were <30,000/mm(3) or <50,000/mm(3) with bleeding.
Results: Of 97 neonates born to PIH mothers 35 (36.1%) had thrombocytopenia. In 20 (20.6%) thrombocytopenia was severe. Higher percentage of thrombocytopenia was associated with male gender (47.7%), low birth weight (71.4%) and prematurity (67.4%). Severe thrombocytopenia was significantly associated with low birth weight (OR: 4.58; 95% CI: 0.98-21.3; p<0.03) and prematurity (OR: 2.52; 95% CI: 0.87-7.24; p<0.05). Material parity, onset of PIH, and medications did not seem to be associated significantly.
Conclusion: Premature and low birth weight neonates born to mothers with pregnancy induced hypertension would require scrutiny for thrombocytopenia during early neonatal period.

In utero exposure to experimental maternal asthma alters fetal airway development in sheep.

Robinson Research Institute, University of Adelaide, Adelaide, South Australia, Australia.
The mechanisms linking maternal asthma (MA) exposure in utero and subsequent risk of asthma in childhood are not fully understood. Pathological airway remodelling, including reticular basement membrane thickening, has been reported in infants and children who go on to develop asthma later in childhood. This suggests altered airway development before birth as a mechanism underlying increased risk of asthma in children exposed in utero to MA.

Background: Our previous study has identified an association of a single nucleotide polymorphism (SNP) in the miR-423 gene with recurrent spontaneous abortion (RSA). The presence of additional RSA-linked SNPs in the miR-423 gene remains unclear.
Methods: We evaluated polymorphisms in the coding region of miR-423 in Han Chinese women with unexplained RSA (URSA).

This research seeks to address the gap in past studies by examining the role of the Nrf2 (nuclear factor erythroid 2-related factor 2) and HO-1 (heme oxygenase-1) signaling pathways in hypoxia and the potential effects of alpha-pinene on these factors. Wistar rats were divided into 7 experimental groups (n = 7): 1) control, 2 and 3) groups receiving alpha-pinene 5 and 10 mg/kg (i.p.

Gestational diabetes mellitus (GDM) significantly disrupts placental structure and function, leading to complications such as intrauterine growth restriction (IUGR) and preeclampsia. This study aimed to investigate the effects of GDM on placental histology, angiogenesis, and oxidative stress, as well as evaluate metformin's protective role in mitigating these changes. A total of 60 pregnant Sprague-Dawley rats were divided into four groups: control, metformin-treated, GDM, and GDM with metformin.
