Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice
Andrology, EarlyView.ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

Andrology, EarlyView.ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Bacterial Flagella Are Firmly Anchored
, 2019 There are mutants of Salmonella enterica (with mutations in fliF and fliL) that shed flagella when they are swimming in a viscous medium or on the surface of soft agar. Filaments with hooks and the distal rod segment FlgG are recovered.

Andrology, EarlyView.ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Clostridioides difficile Flagella
International Journal of Molecular SciencesClostridioides difficile is an important pathogen for humans with a lead in nosocomial infection, but it is also more and more common in communities. Our knowledge of the pathology has historically been focused on the toxins produced by the bacteria that remain its major virulence factors.

International Endodontic Journal, EarlyView.ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...
