The major histocompatibility complex plays a vital role in the vertebrate immune system due to its role in infection, disease and autoimmunity, or recognition of "self". The marsupial MHC class II genes show divergence from eutherian MHC class II genes and are a unique taxon of therian mammals that give birth to altricial and immunologically naïve young providing an opportune study system for investigating evolution of the immune system. Additionally, the MHC in marsupials has been implicated in disease associations, including susceptibility to Chlamydia pecorum infection in koalas...

PROBLEM: The luteinizing hormone (LH), produced by gonadal and nongonadal cells in the anterior pituitary gland play a critical role in human sexual development and reproduction. It is required for the induction of ovulation in females and sex steroid hormone production in both males and females. It is also an important player in early pregnancy events in oviducts and in absence of LH signalling, the uterus cannot initiate pregnancy. LH works through its receptor LHCGR. Therefore, it is quite important to figure out those mutations that have the potential to affect the structure and function of both LH and LHR...

BACKGROUND: An infant's presentation at delivery may be an early indicator of developmental differences. Non-vertex presentation (malpresentation) complicates delivery and often leads to caesarean section, which has been associated with neurodevelopmental delays, including autism spectrum disorder (ASD). However, malpresentation could be an early sign of an existing developmental problem that is also an upstream factor from caesarean delivery. Little research has been done to investigate the association between malpresentation and ASD...

INTRODCTION: Human spermatogenesis is a complex process that transforms spermatogonial stem cells through mitosis and meiosis to spermatozoa. Testosterone is the key regulator of the terminal stages of meiosis, adherence of spermatids to Sertoli cells, and spermiation. Follicle-stimulating hormone (FSH) may be required for early spermatogenesis and is important for maintaining normal spermatogenesis in men. Hormonal contraception suppresses FSH, luteinizing hormone, and intratesticular testosterone concentration, resulting in marked suppression of sperm output...

OBJECTIVE: To investigate the trimester-specific associations between maternal total physical activity level vs moderate-to-vigorous exercise and fetal growth disorders. METHODS: We analyzed 2062 mother-neonate pairs participating in the longitudinal China Medical University Birth Cohort Study. The Pregnancy Physical Activity Questionnaire was used to assess the physical activity level of women during the three trimesters. A higher level of total physical activity was defined as meeting or exceeding the cohort-specific 75th percentile, and a higher level of exercise was defined according to the Physical Activity Guidelines for Americans...

OBJECTIVES: To investigate the prevalence of oligohydramnios, brain sparing, and cardiac dysfunction among a cohort of fetal growth restriction (FGR). METHODS: To assess the prevalence of oligohydramnios amongst a large sample of FGR fetuses, we screened a database of ultrasounds of FGR pregnancies from our maternal-fetal medicine clinics (clinical cohort) for diminished amniotic fluid volume. Using a threshold of a maximum vertical pocket (MVP) of <2 cm for "oligohydramnios," and 2 to 3 cm as a "reduced fluid" group, trends of Doppler values and cardiac parameters were assessed from pregnancies in an ongoing research study (comprehensive cohort)...

Pregnant women represent a high-risk population for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection. The presence of SARS-CoV-2 has been reported in placenta from infected pregnant women, but whether the virus influences placenta immune response remains unclear. We investigated the properties of maternal-fetal interface macrophages (MFMs) in a cohort of unvaccinated women who contracted coronavirus disease 2019 (COVID-19) during their pregnancy. We reported an infiltration of CD163+ macrophages in placenta from COVID-19 women 19 whereas lymphoid compartment was not affected...

A central issue in immunology is the immunological response against nonself. The prerequisite for a specific immunological response is the exposure to the immune system of a nonself antigen. Mathematical equations are presented, which define the fraction of all outcomes with a nonself allele in biallelic systems at the population level in pregnancy and transfusion/transplantation medicine. When designing assays, the mathematical descriptions can be used for estimating the number of genetic markers necessary to obtain a predetermined probability level in detecting nonself alleles of a given frequency...

AIMS: Sertraline is frequently prescribed for mental health conditions in both pregnant and breastfeeding women. According to the limited available data, only small amounts of sertraline are transferred into human milk, yet with a large amount of unexplained interindividual variability. This study aimed to develop a population pharmacokinetic (popPK) model to describe the pharmacokinetics of sertraline during the perinatal period and explain interindividual variability. METHODS: Pregnant women treated with sertraline were enrolled in the multicenter prospective cohort SSRI-Breast Milk study...

Investigators conducting human subject research have typically conveyed only clinically actionable results back to individual participants. Shifting scientific culture around viewing participants as partners in research, however, is prompting investigators to consider returning as much data or results as the participant would like, even if they are not clearly actionable. Expanding return of individual results may add value for individual participants and their communities, refine future research questions and methods, build trust, and enhance retention of participants...

Public health restrictions to protect physical health during the COVID-19 pandemic had unintended effects on mental health, which may have disproportionately affected some potentially vulnerable groups. This scoping review of qualitative research provides a narrative synthesis of new mothers' perspectives on their mental health during COVID-19 pandemic restrictions through pregnancy to the postpartum period. Database searches in PubMed, CINAHL, and PsycINFO sought primary research studies published until February 2023, which focused on new mothers' self-perceived mental health during the pandemic ( N = 55)...
