Dynamics of Gene and Allelic Expression During Modern Hybrid Maize Breeding

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Maize breeding has greatly improved yield through single‐cross hybrids, but the underlying gene regulatory changes remain unclear. This study analysed transcriptomes of landmark maize hybrids and their parents across developmental stages and planting densities.

Resolving a Nearly Two‐Centuries‐Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide

open access: yesChemistry – A European Journal, Volume 32, Issue 9, 2 March 2026.
The crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.

Investigative study on the role of the Toxo 5699 gene in the Toxoplasma gondii lytic cycle using the CRISPR/Cas9 system.

open access: yesTropical biomedicine, 2021
The focus of the current study was to disrupt the Toxo 5699 gene via CRISPR/Cas9 to evaluate the effects of gene disruption on the parasite lytic cycle. In the present work, a single plasmid expressing both the guide RNA and Cas9 nuclease together with a selectable marker of human dihydrofolate reductase (DHFR) was introduced into Toxoplasma gondii ...

Application of Geographically Weighted Regression Analysis to Assess Predictors of Early Sexual Initiation in Ethiopia, EDHS 2016

open access: yesHealth Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Early sexual initiation was defined as the experience of first intercourse before 18 years of age. It has negative health, social, and economic consequences with an increased lifetime prevalence of sexual partners, thereby increasing the risk of exposure to sexually transmitted diseases. Thus, this study aimed to assess the

Long-term survival after venous thromboembolism: a retrospective selected cohort study among young women

open access: yesHaematologica, 2010
Few data are available on long-term survival following venous thromboembolism. We performed a retrospective survival analysis covering the period January 1985 to December 2006 in 728 young women (median age 28.7 years; interquartile range 21.6–36.3 years)

Model‐Free Local Partial Correlation

open access: yesAustralian &New Zealand Journal of Statistics, Volume 68, Issue 1, March 2026.
ABSTRACT In the simple linear regression context, partial correlation measures the linear association between two variables, with the linear effects of a third control variable removed. In this paper, we investigate the local partial correlation using a kernel smoothing approach.

Quelle connaissance et quel impact du droit criminel américain dans la France du xixe siècle ?

open access: yesClio@Themis
At two moments during the 19th century, French jurists were interested in American criminal law, and not only in the overseas prison systems discussed in the 1833 report by de Beaumont and Tocqueville.
