    Abstract This article is contributed by the COBRE for Reproductive Health. The programmatic and scientific goals of this COBRE support a multidisciplinary, translational, and innovative program in women's reproductive health. The research projects focus on using pre-clinical and human models to understand mechanisms of preeclampsia, gestational diabetes, preterm birth, IVF pregnancies, and the application of contemporary computational approaches to identify the networks and pathways underlying these devastating pregnancy complications. We discuss how novel observations emanating from the preeclampsia project can be leveraged to understand chronic diseases such as Alzheimer's disease (AD). Proteinopathy is a hallmark feature of neurodegenerative disorders such as AD. We recently reported that preeclampsia (PE), a severe pregnancy complication, is another prevalent proteinopathy disorder in a younger population. This review provides a comprehensive discussion on shared etiology between PE and AD, establishing a novel blood test for their prediction and diagnosis, and a novel therapeutic option for these disorders.

    Abstract Mann–Kendall (MK) test is a non-parametric technique widely used for trend analysis in time series datasets. However, the datasets tend to be noisy which increases data variance and often results in false rejection of null hypothesis. The present study investigates use of spatial autocorrelation (i.e., contextual information) to address influence of noise in the MK test. By incorporating spatial autocorrelation, the false trend can be identified, while at the same time spatial autocorrelation provides support for strengthening the results. The contextual MK test (CMK) was used for analysing NO₂ trend in the Northern Indian states of Punjab, Haryana, Delhi, Uttar Pradesh, Madhya Pradesh, and Rajasthan during paddy stubble burning, using TROPOspheric Monitoring Instrument total vertical column density data. The serial correlation in the datasets was removed using pre-whitening before running the CMK and conventional MK test. In year 2021, MK test identified 12.9% of the grid cells with monotonous increasing trend of NO₂, which increased to 14.1% when CMK test was used. Similarly, cells with monotonous increasing NO₂ trend in year 2020, were 8.7% and 9.5% using MK and CMK tests respectively. Thus, CMK test was able to identify more cells having a monotonous increasing trend of NO₂ compared to the MK test, while at the same time the spurious trend could also be efficiently handled. Subsequently, using CMK test state-wise analysis of NO₂ trend was also carried out.

    Abstract Pathogens comprised of viruses, bacteria, gut microbiome, and parasites are a leading cause of ever-emerging diseases in humans. Studying pathogens for their ability to cause diseases is a topic of critical discussion among scientists and pharmaceutical centers for effective drug development that diagnose, treat, and prevent infection-associated disorders. Pathogens impact health either directly by invading the host or by eliciting an acute inflammatory immune response. This paradigm of inflammatory immune responses is even more consequential in people who may be immunocompromised. In this regard, pregnancy offers an altered immunity scenario, which may allow the onset of severe diseases. Viruses, such as Influenza, HIV, and now SARS-CoV-2, associated with the COVID-19 pandemic, raise new concerns for maternal and fetal/neonatal health. Intrauterine bacterial and parasitic infections are also known to impact pregnancy outcomes and neonatal health. More importantly, viral and bacterial infections during pregnancy have been identified as a common contributor to fetal brain development defects. Infection-mediated inflammatory uterine immune milieu is thought to be the main trigger for causing poor fetal brain development, resulting in long-term cognitive impairments. The concept of in utero programming of childhood and adult disorders has revolutionized the field of neurodevelopment and its associated complications. Recent findings in mice and humans clearly support the idea that uterine immunity during pregnancy controls the health trajectory of the child and considerably influences the cognitive function and mental health. In this review, we focus on the in utero programming of autism spectrum disorders (ASD) and assess the effects of pathogens on the onset of ASD-like symptoms.

    Abstract Our prior studies have shown that protein misfolding and aggregation in the placenta are linked to the development of preeclampsia, a severe pregnancy complication. We identified transthyretin (TTR) as a key component of the aggregated protein complex. However, the regulation of native TTR in normal pregnancy remains unclear. In this study, we found that pregnant mice exhibited a remarkable and progressive decline in serum TTR levels through gestational day (gd) 12–14, followed by an increase in late pregnancy and postpartum. Meanwhile, serum albumin levels showed a modest but statistically significant increase throughout gestation. TTR protein and mRNA levels in the liver, a primary source of circulating TTR, mirrored the changes observed in serum TTR levels during gestation. Intriguingly, a similar pattern of TTR alteration was also observed in the serum of pregnant women and pregnant interleukin-10-knockout (IL-10⁻/⁻) mice with high inflammation background. In non-pregnant IL-10⁻/⁻ mice, serum TTR levels were significantly lower than those in age-matched wild-type mice. Administration of IL-10 to non-pregnant IL-10⁻/⁻ mice restored their serum TTR levels. Notably, dysregulation of TTR resulted in fewer implantation units, lower fetal weight, and smaller litter sizes in human TTR-overexpressing transgenic mice. Thus, TTR may play a pivotal role as a crucial regulator in normal pregnancy, and inflammation during pregnancy may contribute to the downregulation of serum TTR presence.

    Abstract Colorimetric sensors have emerged as a powerful tool in the detection of water pollutants. Plasmonic nanoparticles use localized surface plasmon resonance (LSPR)-based colorimetric sensing. LSPR-based sensing can be accomplished through different strategies such as etching, growth, aggregation, and anti-aggregation. Based on these strategies, various sensors have been developed. This review focuses on the newly developed anti-aggregation-based strategy of plasmonic nanoparticles. Sensors based on this strategy have attracted increasing interest because of their exciting properties of high sensitivity, selectivity, and applicability. This review highlights LSPR-based anti-aggregation sensors, their classification, and role of plasmonic nanoparticles in these sensors for the detection of water pollutants. The anti-aggregation based sensing of major water pollutants such as heavy metal ions, anions, and small organic molecules has been summarized herein. This review also provides some personal insights into current challenges associated with anti-aggregation strategy of LSPR-based colorimetric sensors and proposes future research directions.
