Placental diseases associated with assisted reproductive technology.

Reprod Biol 2021 Apr 12;21(2):100505. Epub 2021 Apr 12.

Department of Obstetrics and Gynecology, Tangdu Hospital, Air Force Military Medical University, Xi'an, 710038, China.

The placenta develops from the outer trophoblastic layer following the differentiation of the fertilized ovum and is therefore more susceptible to epigenetic regulatory changes caused by environmental interventions and influences during assisted reproductive technology. Furthermore, the placenta regulates the development of the fetal heart, brain, kidneys, bones, and other tissues and organs [1]. Placental dysplasia leads to poor perinatal outcomes as well as long-term health risks later in life, including neurodevelopmental disorders, tumors, and adult metabolic syndrome [2,3]. Read More

Galanin and prolactin expression in relation to parental care in two sympatric cichlid species from Lake Tanganyika.

Gen Comp Endocrinol 2021 Apr 13:113785. Epub 2021 Apr 13.

Konrad Lorenz Institute of Ethology, Department of Interdisciplinary Life Sciences, University of Veterinary Medicine Vienna, Austria.

Our understanding of the hormonal mechanisms underlying parental care mainly stems from research on species with uniparental care. Far less is known about the physiological changes underlying motherhood and fatherhood in biparental caring species. Here, using two biparental caring cichlid species (Neolamprologus caudopunctatus and Neolamprologus pulcher), we explored the relative gene-expression levels of two genes implicated in the control of parental care, galanin (gal) and prolactin (prl).

Assessing saddle-billed stork (Ephippiorhynchus senegalensis) pair-bonds and breeding behavior using behavior observed during multiple breeding seasons.

Zoo Biol 2021 Apr 16. Epub 2021 Apr 16.

Disney's Animal Kingdom®, Disney's Animals, Science, and Environment, Lake Buena Vista, Florida, USA.

Despite the fact that saddle-billed storks (SBS) are housed in zoos around the world, few successful hatches have been recorded. At Disney's Animal Kingdom® we conducted observations on two pairs of SBS during multiple reproductive periods to assess the relative strength of their pair-bonds and their reproductive success. We accomplished this through observations of rates of social behaviors, such as wing displays and aggression, rates of nest construction, time on and near the nest, and egg production. Read More

Effect of maternal praziquantel treatment for Schistosoma japonicum infection on the offspring susceptibility and immunologic response to infection at age six, a cohort study.

PLoS Negl Trop Dis 2021 Apr 16;15(4):e0009328. Epub 2021 Apr 16.

Research Institute for Tropical Medicine, Manila, The Philippines.

In areas endemic to schistosomiasis, fetal exposure to schistosome antigens prime the offspring before potential natural infection. Praziquantel (PZQ) treatment for Schistosoma japonicum infection in pregnant women has been demonstrated to be safe and effective. Our objectives were to evaluate whether maternal PZQ treatment modifies the process of in utero sensitization to schistosome antigens potentially impacting later risk of infection, as well as immune response to S.

In the near future, pediatricians will increasingly encounter severely allergic children undergoing FA-OIT. FA-OIT consists in daily ingestion of increasing doses of the allergen during the up-dosing phase, and ingestion of a constant dose during the maintenance phase. Read More

Combining phenolic grafting and laccase-catalyzed cross-linking: Effects on structures, technofunctional properties and human immunoglobulin E binding capacity of egg white proteins.

Food Chem 2021 Mar 13;355:129587. Epub 2021 Mar 13.

Department of Biocatalysis, Institute of Catalysis and Petrochemistry CSIC, Campus UAM, 28049 Madrid, Spain.

The efficiency of laccase-catalyzed protein cross-linking can be impacted by substrate protein structure and competing reactions. In this study, chemical grafting of ferulic acid (FA) on protein surface was applied to modulate the cross-linking of two inflexible globular proteins, lysozyme (LZM) and ovalbumin (OVA). The extent of FA-grafting was positively correlated with protein cross-linking extent, and determined the molecular weight profile and structures of the cross-linked product. Read More

Noncovalent molecular interactions between antineoplastic drug gemcitabine and a carrier protein identified through spectroscopic and in silico methods.

Int J Biol Macromol 2021 Apr 12. Epub 2021 Apr 12.

Surfactant Research Chair, Department of Chemistry, King Saud University, P.O. Box-2455, Riyadh 11451, Saudi Arabia.

Herein we have studied the noncovalent molecular interactions between hen egg white lysozyme (HEWL) and the commonly employed antineoplastic drug gemcitabine through the cumulative implementation of spectroscopic techniques and in silico approaches. The formation of a complex between HEWL and gemcitabine was made evident by the differences between the UV-visible spectra of the protein and protein-gemcitabine complex. Fluorescence quenching of HEWL by gemcitabine was hardly detectable at room temperature, but it became prominent at higher temperatures. Read More

Seasonality of Aedes albopictus in North and Central Mississippi.

J Am Mosq Control Assoc 2021 Mar;37(1):34-37

Container-breeding mosquitoes are increasingly important in public health due to recent outbreaks of Zika virus, chikungunya, and dengue. This paper documents seasonality of the most prevalent container-breeding mosquito species in Mississippi-Aedes albopictus. Ten sites in 5 counties in both northern and central Mississippi (20 sites, 10 counties total) were sampled by larval dipping and oviposition traps biweekly from September 2016 to June 2019, totaling 22 months and potentially yielding 440 egg or larval collections.

Mycobacteria In Skin Lesions and the Habitat of the Endangered Houston Toad (Anaxyrus houstonensis).

J Wildl Dis 2021 Apr 15. Epub 2021 Apr 15.

Texas State University, Department of Biology, 601 University Drive, San Marcos, Texas 78666, USA.

Head-starting of the federally endangered Houston toad (Anaxyrus houstonensis), that is, the release of egg strands, tadpoles, and metamorphic juveniles produced in captivity into the original breeding ponds, requires assessment of potential threats for the transmission of pathogens from captive to free-ranging toads. We used Illumina-based 16S rRNA V3 amplicon sequencing to investigate the community structure of bacteria from skin lesions of captive Houston toad and habitat (pond) samples. Proteobacteria, alone or together with Actinobacteria and, in some samples, Cyanobacteria represented virtually all reads in tissue lesion samples, whereas pond samples were much more diverse, with Acidobacteria, Actinobacteria, Bacteriodetes, Chloroflexi, Cyanobacteria, Firmicutes, Planctomycetes, Proteobacteria, and Verrucomicrobia present with little variation between samples.
