The Lupus Damage Index Revision Program: Results From the Item Generation and Reduction Phases

open access: yesArthritis Care &Research, EarlyView.
Objective A data‐driven and expert/patient consensus‐based project to develop a revised Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI) is under way supported by SLICC, ACR, and the Lupus Foundation of America. Our objective is to report the item generation and reduction phase results

Paternal Sperm Gnas‐ICR Epigenetic Programming Contributes to PPP‐Like Phenotypes in Female Offspring

open access: yesAdvanced Science, EarlyView.
A paternal glucocorticoid–sperm Gnas‐ICR axis is linked to ovarian endocrine programming in female offspring. Paternal preconception caffeine exposure elevates corticosterone, promotes sperm Gnas‐ICR hypermethylation, and is associated with ovarian Gnas upregulation, cAMP/PKA/CREB–StAR activation, enhanced estradiol synthesis, and PPP‐like phenotypes ...

Sperm defects and infertility caused by bacterial infection of the reproductive tract in an adult male dog: A case report

open access: yesAsian Pacific Journal of Reproduction, 2018
Cases of acquired infertility in dogs often have poor prognosis and can be frustrating to clinicians in canine practice. In this case, a 3.5-year-old male Caucasian dog was presented for infertility evaluation.

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

open access: yesAdvanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

open access: yesAdvanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Association between DNA Fragmentation Index and Sperm Morphological Abnormali-ties among Patients at Shokoufeh Infertility Treatment Center, 2023–2025 [PDF]

open access: yesIranian South Medical Journal
Background: Sperm morphological abnormalities and aberrant chromatin maturation are considered important indicators of male fertility. Assessing sperm structural anomalies and DNA damage plays a critical role in evaluating male reproductive potential ...

Incidence of Cervicitis in Infertile Women: A Study in Medical Center Clinic, Makassar City, Indonesia

open access: yesDiversity
Infertility is a significant global health concern, yet the role of cervicitis as an independent risk factor remains inadequately explored. While previous studies have investigated various causes of infertility, limited research has specifically examined

Long Noncoding RNA PCALRx Interacts with Pyruvate Carboxylase to Drive Multi‐Organ Developmental Toxicity in Zebrafish Embryos Exposed to Amoxicillin

open access: yesAdvanced Science, EarlyView.
Embryonic amoxicillin exposure disrupts multi‐organ development in zebrafish larvae through a lncRNA–metabolic enzyme regulatory axis. PCALRx associates with pyruvate carboxylase, promotes PC protein ubiquitination, and impairs mitochondrial energy metabolism, while vitamin B1 partially restores PC‐centered metabolic function and developmental outcomes.

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

open access: yesAdvanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...
