Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

Reliability of the comet assay in cryopreserved human sperm

open access: yes, 2002
Background: Although the comet assay has potential value for measuring DNA damage in large epidemiological human sperm studies, it is impractical to perform the assay daily on fresh semen samples. Therefore, before its use in epidemiological studies, the

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency

open access: yesEpilepsia, EarlyView.
Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

A rare case of perineal neuralgia treated with ultrasound‐guided nerve block combined with water separation

open access: yesIbrain, Volume 11, Issue 1, Page 106-111, Spring 2025.
A middle‐aged man presented with a right indirect inguinal hernia in November 2020 and underwent laparoscopic high ligation of the right hernial sac. Intermittent acupuncture‐like pain in the skin of the right scrotum and medial thigh occurred 1 month after surgery and lasted for 6 months. Under ultrasound guidance, ilioinguinal nerve and genitofemoral
