CSF1-R inhibition attenuates posttraumatic osteoarthritis and quadriceps atrophy following ligament injury.

Knee osteoarthritis contributes substantially to worldwide disability. Post-traumatic osteoarthritis (PTOA) develops secondary to joint injury, such as ligament rupture, and there is increasing evidence suggesting a key role for inflammation in the aetiology of PTOA and associated functional deficits. Colony stimulating factor 1 receptor (CSF1-R) has been implicated in the pathogenesis of musculoskeletal degeneration following anterior cruciate ligament (ACL) injury.

Can the Bladder Itself "Measure" Volume, and Thereby Help to Determine When Initiation of Voiding Should Occur? ICI-RS 2024.

Aims: To answer the question of whether the bladder itself can to any extent control or modulate the initiation of voiding.

Methods: This subject was discussed at the International Consultation on Incontinence-Research Society (ICI-RS) 2024 conference in Bristol, UK in a proposal session.

Results: Cells in the bladder wall sense the local environment via a diverse array of ion channels and receptors which together provide input to motor-sensory and signal transduction mechanisms.

State drug caps associated with fewer Medicaid-covered prescriptions for opioid use disorder, 2017-2022.

The Medicaid program is the largest payer of opioid use disorder (OUD) treatment, including medications for OUD (MOUD). Because of budget neutrality requirements, some Medicaid programs use prescription drug caps to limit the monthly number of prescriptions an enrollee can fill. This study examined the association between Medicaid prescription drug caps and Medicaid-covered prescriptions for 2 forms of MOUD (buprenorphine and naltrexone) from 2017 to 2022 using fee-for-service and managed care data from Medicaid's State Drug Utilization Data.

What do we really know about the external urethral sphincter?

The external urethral sphincter (EUS), composed of skeletal muscle, along with a smooth muscle-lined internal urethral sphincter (IUS), have crucial roles in maintaining continence during bladder filling and facilitating urine flow during voiding. Disruption of this complex activity has profound consequences on normal lower urinary tract function during the micturition cycle. However, relatively little is known about the normal and pathological functions of these particular muscle types, how activity can be manipulated and regulated and why, for example, loss of EUS function and sarcopenia is associated with ageing.

DNA hypomethylation promotes UHRF1-and SUV39H1/H2-dependent crosstalk between H3K18ub and H3K9me3 to reinforce heterochromatin states.

Mono-ubiquitination of lysine 18 on histone H3 (H3K18ub), catalyzed by UHRF1, is a DNMT1 docking site that facilitates replication-coupled DNA methylation maintenance. Its functions beyond this are unknown. Here, we genomically map simultaneous increases in UHRF1-dependent H3K18ub and SUV39H1/H2-dependent H3K9me3 following DNMT1 inhibition.
