Harrison Massey University Abstract I believe most acts of human procreation are immoral, and I believe this despite also believing in the truth of moral particularism. In this paper I explain why. I argue that procreative acts possess numerous features that, in other contexts, seem typically to operate with negative moral valences. Other things being equal this gives us reason to believe they will operate negatively in the context of procreative acts as well. However, most people’s intuitions represent procreative acts to be morally permissible in most circumstances. Given moral particularism, this would normally be good evidence that procreative acts are indeed morally permissible and that the features that operate negatively elsewhere, simply do not do so in the context of procreative acts in particular. But I argue that we have no good reason to think our intuitions about the ethics of human procreation are accurate.

Amis, Jwala Renukuntla, Pradeep Kumar Bolla and Bradley A. Clark * Department of Basic Pharmaceutical Sciences, Fred Wilson School of Pharmacy, High Point University, High Point, NC 27268, USA; [email protected] (T.M.A.); [email protected] (J.R.); [email protected] (P.K.B.) * Correspondence: [email protected]; Tel.: +1-336-841-9665 Received: 18 August 2020; Accepted: 16 September 2020; Published: 19 September 2020 Abstract: Cryoprotectants are often required in lyophilization to reduce or eliminate agglomeration of solute or suspended materials. The aim of this study was to select a cryoprotecting agent and optimize its concentration in a solid lipid nanoparticle formulation. Progesterone-loaded stearic acid solid lipid nanoparticles (SA-P SLNs) were prepared by hot homogenization with high speed mixing and sonication. The stearic acid content was 4.6% w/w and progesterone was 0.46% w/w of the initial formulation. Multiple surfactants were evaluated, and a lecithin and sodium taurocholate system was chosen. Three concentrations of surfactant were then evaluated, and a concentration of 2% w/w was chosen based on particle size, polydispersity, and zeta potential. Agglomeration of SA-P SLNs after lyophilization was observed as measured by increased particle size. Dextran, glycine, mannitol, polyvinylpyrrolidone (PVP), sorbitol, and trehalose were evaluated as cryoprotectants by both an initial freeze–thaw analysis and after lyophilization. Once selected as the cryoprotectant, trehalose was evaluated at 5%, 10%, 15%, and 20% for optimal concentration, with 20% trehalose being finally selected as the level of choice.

  • Sperm Cryopreservation: a Review on Current Molecular Cryobiology and Advanced Approaches
    1 RBMO VOLUME 00 ISSUE 0 2018 REVIEW Sperm cryopreservation: A review on current molecular cryobiology and advanced approaches BIOGRAPHY Abdolhossein Shahverdi is Professor of Embryology and scientific director of the Sperm Biology Group at the Royan Institute in Tehran. His main research interests are fertility preservation, reproductive epigenetic and germ cell biology. With over 20 years’ experience in reproductive biology, he has published more than 120 international scientific papers. Maryam Hezavehei1,2, Mohsen Sharafi3,*, Homa Mohseni Kouchesfahani2, Ralf Henkel4, Ashok Agarwal5, Vahid Esmaeili1, Abdolhossein Shahverdi1,* KEY MESSAGE Understanding the new aspects of sperm cryobiology, such as epigenetic and proteomic modulation, as well as novel techniques, is essential for clinical applications and the improvement of ART protocols. Long-term follow-up studies on the resultant offspring obtained from cryopreserved spermatozoa is recommended for future studies. ABSTRACT The cryopreservation of spermatozoa was introduced in the 1960s as a route to fertility preservation. Despite the extensive progress that has been made in this field, the biological and biochemical mechanisms involved in cryopreservation have not been thoroughly elucidated to date. Various factors during the freezing process, including sudden temperature changes, ice formation and osmotic stress, have been proposed as reasons for poor sperm quality post-thaw. Little is known regarding the new aspects of sperm cryobiology, such as epigenetic and proteomic modulation of sperm and trans-generational effects of sperm freezing. This article reviews recent reports on molecular and cellular modifications of spermatozoa during cryopreservation in order to collate the existing understanding in this field. The aim is to discuss current freezing techniques and novel strategies that have been developed for sperm protection against cryo-damage, as well as evaluating the probable effects of sperm freezing on offspring health.

  • To Intercontinental to Interplanetary to Intersolar
    Why Editorials? Why some, not all? In compiling the MMM Classics volumes, with precious few exceptions, editorials were not included. Why? Yes, some addressed temporary conditions, and are of no lasting interest. But indeed, many MMM editorials through the years have addressed concerns that remain pertinent today, if indeed they are not timeless. So we have taken another look and here reprint those “In Focus” editorials that, we think, speak to conditions and issues still very relevant today. These pieces represent the editor’s opinions alone, and have never been presented as the opin- ions or policies of the Lunar Reclamation Society, the National Space Society, the Artemis Society, or the Moon Society. There are none for the first year, as we didn’t start writing editorials until MMM #11. The Topics: The relation between the Moon and Mars in Manned Space Exploration Policy is clearly the num- ber one issue addressed. What we mean by “space” difers widely among “space proponents.” This is a critical issue. Space is more than the boundary layer of Earth, a place for space stations and satellites. This is a realm already part of Earth’s “econosphere” and will take care of itself. It is the endless fron- tier, beyond that needs our attention. The endless hiatus between Apollo 17 and what we all want to come next is a key topic. There is much we can do to make the next human lunar opening a stronger and more lasting one. Asteroids, promise and threat, are looked at and put in perspective with a nearer term threat: space debris, which could end up confining humans forever on our home world.

  • Effects of Sample Treatments on Genome Recovery Via Single-Cell Genomics
    The ISME Journal (2014) 8, 2546–2549 & 2014 International Society for Microbial Ecology All rights reserved 1751-7362/14 www.nature.com/ismej SHORT COMMUNICATION Effects of sample treatments on genome recovery via single-cell genomics Scott Clingenpeel1, Patrick Schwientek1, Philip Hugenholtz2 and Tanja Woyke1 1DOE Joint Genome Institute, Walnut Creek, CA, USA and 2Australian Centre for Ecogenomics, School of Chemistry and Molecular Biosciences, University of Queensland, Brisbane, Queensland, Australia Single-cell genomics is a powerful tool for accessing genetic information from uncultivated microorganisms. Methods of handling samples before single-cell genomic amplification may affect the quality of the genomes obtained. Using three bacterial strains we show that, compared to cryopreservation, lower-quality single-cell genomes are recovered when the sample is preserved in ethanol or if the sample undergoes fluorescence in situ hybridization, while sample preservation in paraformaldehyde renders it completely unsuitable for sequencing. The ISME Journal (2014) 8, 2546–2549; doi:10.1038/ismej.2014.92; published online 13 June 2014 Relatively little is known about the functioning of genomes from single cells. Three methods of sample complex microbial communities, largely due to the preservation were tested: cryopreservation with difficulty in culturing most microbes (Rappe and 20% glycerol as a cryoprotectant, preservation in Giovannoni, 2003). Although metagenomics can 70% ethanol, and preservation in 4% paraformalde- provide information on the genetic capabilities of hyde. Because paraformaldehyde treatment causes the entire community, it is difficult to connect crosslinks between nucleic acids and proteins, we predicted gene functions to specific organisms using tested cells exposed to 4% paraformaldehyde with metagenomics (Morales and Holben, 2011).
