Evidence for evolution of a new sex chromosome within the haploid‐dominant Marchantiales plant lineage

open access: yesJournal of Integrative Plant Biology, EarlyView.
Genomic evidence suggests that sex chromosomes may not be conserved within liverworts. Re‐evolution of dioicy in the genus Riccia may have occurred with probable de novo establishment of a new sex chromosome from the autosome, and the m‐chromosomes have evolved independently from chromosomes in the Marchantiales.

Global identification of key genes for pollen germination in rice through high‐throughput screening and gene editing

open access: yesJournal of Integrative Plant Biology, EarlyView.
A systematic examination of 107 T‐DNA insertional lines targeting 105 genes preferentially expressed in late pollen development identified 42 lines exhibiting significant deviations from expected Mendelian segregation ratios, suggesting a potential involvement in pollen viability and germination.

Fracture resistance and behavior of endodontically treated maxillary premolars with varying ferrule heights and post numbers: A laboratory study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To investigate how varying ferrule heights and the number of glass fiber posts affect fracture resistance and behavior of endodontically treated maxillary first premolars with substantial loss of tooth structure. Materials and Methods Twenty‐four extracted endodontically treated human maxillary first premolars were divided into three ...

Differences in Milk Production Efficiency and Physiology Between Lactating Holstein Cows and Yaks Born and Kept at About 4000 m of Altitude When Fed the Same Diet

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Yaks (Bos grunniens) have developed numerous mechanisms to cope with hypoxic environments. Still, as their milk yield is low, the use of production systems building on dairy breeds at high altitude might increase efficiency, but this has not yet been explored.

Biomaterials for Reconstructive Treatment of Peri‐Implantitis

open access: yesJournal of Periodontal Research, EarlyView.
Reconstructive therapy should be implemented in contained defects. Various bone filler materials with or without a barrier membrane and/or adjunctive biologics may be applied. ABSTRACT Peri‐implantitis is a pathological condition affecting the tissues surrounding dental implants, marked by inflammation of the peri‐implant connective tissue and ...
