SYPHILIS OF THE EPIDIDYMIS [PDF]

open access: yesJournal of the American Medical Association, 1919
Syphilitic involvement of the epididymis or cord, independent of disease of the testicles, is rare, and, if present, is overlooked in the examination of patients when one is searching for signs of syphilitic infection. The discovery of several cases of infiltrated epididymides and thickened cords, due to syphilis, led to a search for more minute ...

Endobody: Genetically Encodable Nanobody‐CPP Chimeras for Degradation of Membrane and Extracellular Proteins

open access: yesAdvanced Science, EarlyView.
We introduced genetically encodable, receptor‐independent nanobody‐CPP chimeras, termed endobodies, as robust and modular membrane protein degraders. Additionally, proteasome‐targeting domain (PTD)‐tethered endobody demonstrates further enhanced degradation potency.

Busulfan administration replicated the characteristics of the epididymal initial segment observed in mice lacking testis-epididymis lumicrine signaling

open access: yesThe Journal of Reproduction and Development
The physiological functions of the mammalian epididymis are typically regulated by the testes. In addition to sex steroids secreted by testicular Leydig cells, which act on the epididymis in an endocrine manner, there is a non-sex-steroidal signaling ...

Pathological Abnormalities Observed on Ultrasonography among Fishermen Associated with Male Genital Schistosomiasis (MGS) along the South Lake Malawi Shoreline in Mangochi District, Malawi

open access: yesTropical Medicine and Infectious Disease, 2022
Schistosome eggs cause granulomata and pathological abnormalities, detectable with non-invasive radiological techniques such as ultrasonography which could be useful in male genital schistosomiasis (MGS).

NAD+ Metabolism Licenses Zygotic Genome Activation via PARP7‐Mediated ADP‐Ribosylation of UHRF1 in Mouse Early Embryos

open access: yesAdvanced Science, EarlyView.
This study uncovers a metabolic‐epigenetic axis licensing zygotic genome activation (ZGA) in mouse embryos. A developmental decline in NAD+ levels activates PARP7, which mono‐ADP‐ribosylates and stabilizes UHRF1. This modification promotes the establishment of permissive histone acetylation marks, thereby facilitating timely ZGA.

Morphological changes of cauda epididymis, sperm infiltration into cauda epididymis, sperm storage and sperm disappearance of cauda epididymis in Rhinolophus ferrumequinum korai (Chiroptera: Rhinolophidae)

open access: yesThe European Zoological Journal, 2018
In this study to investigate the male reproductive cycle of Rhinolophus ferrumequinum korai, we focused on monthly morphological changes of cauda epididymis, sperm infiltration into cauda epididymis, sperm storage and sperm destruction.

Mitochondrial Functionality in Male Fertility: From Spermatogenesis to Fertilization

open access: yesAntioxidants, 2021
Mitochondria are structurally and functionally distinct organelles that produce adenosine triphosphate (ATP) through oxidative phosphorylation (OXPHOS), to provide energy to spermatozoa. They can also produce reactive oxidation species (ROS).

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

open access: yesAdvanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

The significance of single-cell transcriptome analysis in epididymis research

open access: yesFrontiers in Cell and Developmental Biology
As a crucial component of the male reproductive system, the epididymis plays multiple roles, including sperm storage and secretion of nutritive fluids for sperm development and maturation.

eEF1G Orchestrates Translation to Ensure Meiotic Progression in Transcriptionally Quiescent Spermatocytes

open access: yesAdvanced Science, EarlyView.
eEF1G supports translation elongation of meiotic mRNAs in transcriptionally quiescent leptotene and zygotene spermatocytes. Its depletion in germ cells causes meiotic arrest at the zygotene stage, with defective homologous synapsis and unstable recombination intermediates.
