Hypertensive disorders of pregnancy (HDP), particularly pre-eclampsia and eclampsia, remain one of the leading causes of maternal mortality and are contributory in many foetal/newborn deaths. This editorial discusses a supplement of seven papers which provide the results of the first round of the CLIP (Community Level Interventions for Pre-eclampsia) Feasibility Studies. These studies report a number of enablers and barriers in each setting, which have informed the implementation of a cluster-randomized trial (cRCT) aimed at reducing pre-eclampsia-related, and all-cause, maternal and perinatal mortality and major morbidity using community-based identification and treatment of pre-eclampsia in selected geographies of Nigeria, Mozambique, Pakistan and India...

Perinatal mortality is relatively high in dogs, with deaths peaking around the time of birth and during the first week of age. Among the several causes of canine perinatal mortality, whelping is the greatest cause. Therefore, early neonatal assistance at birth should be mandatory with dogs. In comparison with human neonatology, knowledge and technological ability in canine neonatology is tremendously scarce. The Apgar score for the newborn viability assessment at birth represents a feasible method for the prompt recognition of newborns that will need special assistance immediately after birth...

Chondrocyte apoptosis is the most important element of development and progression of osteoarthritis (OA). Nitric oxide (NO) was used as the agent to induce chondrocyte apoptosis. Carboxymethylated chitosan (CMCS) has anti-apoptosis effect on many cell types in vitro. This study was designed to investigate the protective effect of CMCS on NO-induced chondrocyte apoptosis and the probable molecular mechanisms. The newborn Sprague-Dawley (SD) rats were used in this study for isolation of chondrocytes. The cell viability was determined by cell counting kit (CCK-8), cell apoptosis was detected by Annexin-V/PI double staining assay kit...

BACKGROUND: Hypoxia/ischemia (HI) brain injury is a common central nervous system insult in newborns. Studies have demonstrated bioactivity of ginsenoside Rg1 in increasing neural viability and promoting angiogenesis. However, there are few reports on roles of Rg1 in brain repair of neonatal HI, and the mechanisms involved are unclear. METHODS: a neonatal HI model was established by a modified Rice-Vannucci model (RVM) and pups received ginsenoside Rg1 or monosialotetrahexosyl ganglioside (GM1) treatment...

PURPOSE: It is well known that a high-dose of ionizing radiation is sufficient to break DNA strands, which leads to elevated genotoxic risks; however, the risks associated with low doses of ionizing radiation remain unclear. In addition, there is little data about the effect of low-dose ionizing radiation on human-derived embryo, newborn and child cells. We investigated the frequency of micronucleus (MN) formation in these cells to understand the genotoxic effects of ionizing radiation...

Unconjugated bilirubin (UCB) in newborns may lead to bilirubin neurotoxicity. Few studies investigated the activation of endoplasmic reticulum stress (ER stress) by UCB. We performed an in vitro comparative study using undifferentiated SH-SY5Y, differentiated GI-ME-N neuronal cells and human U87 astrocytoma cells. ER stress and its contribution to inflammation and apoptosis induced by UCB were analyzed. Cytotoxicity, ER stress and inflammation were observed only in neuronal cells, despite intracellular UCB accumulation in all three cell types...

Griseofulvin (GRF) is an important antifungal drug with low bioavailability and, for this reason, a topical formulation with a targeted action and minimal systemic effects, appears to be a preferable solution. GRF poor solubility has limited the development of topical formulations and their release to the market. The aim of this work was to prepare a new GRF formulation for topical application using lipid-based nanosystems; to study its permeation and penetration, cell viability and to evaluate its therapeutic action...

Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth...
