Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

Plant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Extreme Polyploidy Reveals Functional Trade‐Offs in Plant Drought Responses

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyploidy shapes plant physiology and anatomy, yet the extent to which different ploidy levels influence drought responses remains unclear. Here, we investigated how ploidy affects cell‐level coordination and functional traits associated with water transport and retention.

Critical Windows of Air Pollution Exposure During Spermatogenesis and Intrauterine Insemination Outcomes

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Male preconception health remains a critically under‐addressed area of family planning. While research suggests air pollution may harm semen quality, downstream impacts on pregnancy, particularly for more vulnerable infertility treatment populations, are understudied.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Identification of a Circular RNA as a Potential Diagnostic and Prognostic Biomarker in Breast Cancer Through Integrated Bioinformatic and Experimental Analyses

Analytical Science Advances, Volume 7, Issue 2, December 2026.
Forty circular RNAs were found to be significantly dysregulated in microarray datasets. Expression levels of hsa_circ_0000231 were significantly upregulated in breast cancer (BC) tissues, while hsa_circ_0011385 exhibited no significant difference in expression levels. This study also revealed that hsa_circ_0000231/hsa‐miR‐5683/CCNB1 regulatory axis may

Preliminary study documents variable accuracy and inclusion among biology instructor gender/sex definitions

Natural Sciences Education, Volume 55, Issue 2, December 2026.
Abstract Society generally presents sex inaccurately as a binary variable based on one or few trait(s), causing myriad issues, including the pursuit of reductionist biology experiments, the creation of laws that limit the rights of women, people with queer genders, and intersex folks, and greater student endorsement of gender stereotypes in ...
