Cardiac Resynchronization Therapy: A Review, Caique M Ternes, Jitae A Kim, Anirban Basu, Kenneth A Ellenbogen, Mihail G Chelu

Faculty, Staff and Students Publications

Importance: Heart failure (HF) affects more than 64 million individuals worldwide, and acute HF is associated with 1-year mortality rates of 23.6% in North America and Europe. Cardiac dyssynchrony from conduction system disease may cause HF progression, particularly in patients with left ventricular (LV) systolic dysfunction.

Observations: Electrical dyssynchrony in HF most commonly presents as left bundle-branch block and affects 20% to 30% of patients with reduced LV ejection fraction (LVEF). Cardiac resynchronization therapy, which includes biventricular pacing and conduction system pacing, restores synchronous ventricular contraction and is recommended for patients with symptomatic HF despite optimal medical therapy, LVEF of …

2020-Current year OA Pubs

Histone deacetylase inhibitors (HDACis) have emerged as valuable therapeutics for cancer and other diseases; however, their effects on histone post-translational modification remain poorly characterized. Here, we applied quantitative mass spectrometry and high-throughput sequencing to systematically profile site-specific changes in histone modifications in response to a panel of HDACis. This platform enabled mapping of histone modification changes across hundreds of sites, including low-abundance histone marks. Furthermore, an integrative analysis of chromatin immunoprecipitation followed by sequencing (ChIP-seq) and RNA-sequencing (RNA-seq) data identified genome-wide binding sites for the low-abundance histone modification of H2A.Z acetylation in HeLa and MDA-MB-231 breast cancer cells, highlighting the …

Wills Eye Hospital Papers

OBJECTIVE: Proliferative vitreoretinopathy (PVR) remains a major cause of failure after rhegmatogenous retinal detachment repair and lacks effective pharmacologic therapies. Although epithelial-mesenchymal transition (EMT) is central to PVR pathogenesis, the structural determinants governing the tractability of EMT regulators, particularly those involving intrinsic disorder, remain poorly defined. We developed a disorder-aware, artificial intelligence-enabled computational framework to evaluate EMT-associated proteins in PVR and prioritize structurally tractable regulators for structure-based targeting.

DESIGN: A computational, hypothesis-generating study employing an in silico screening and structural modeling pipeline.

SUBJECTS: No human subjects or biological specimens were included. The dataset comprised 25 EMT-associated proteins implicated in PVR, …

Sultan Qaboos University Medical Journal

Type IV sacrococcygeal teratomas (SCTs) are the rarest subtype of SCTs. We report a 2-week-old female who presented to a tertiary care centre in Muscat, Oman, in 2024 with abdominal distension and feeding intolerance. Imaging revealed a purely cystic presacral lesion, managed with successful laparoscopic-assisted cyst excision and coccygectomy. Histopathology confirmed a mature cystic SCT and the patient was diagnosed with a purely cystic Altman type IV SCT. The postoperative course was uneventful apart from minor wound dehiscence, which resolved with conservative management. Follow-up showed complete wound healing and no recurrence. Purely cystic Type IV SCTs are extremely rare and …

Smaller Right Ventricle Results In Poorer Exercise Performance In Young Patients With Repaired Tetralogy Of Fallot, Christiane Mhanna, Katerina Kourpas, Takeshi Tsuda

Department of Pediatrics Faculty Papers

BACKGROUND: Severe right ventricular (RV) dilatation and exercise intolerance are considered indications for pulmonary valve replacement in surgically repaired tetralogy of Fallot (rTOF).

METHODS AND RESULTS: Cardiopulmonary exercise testing (CPET) and cardiac magnetic resonance (CMR) were performed in rTOF patients with pulmonary insufficiency (PI). Oxygen pulse (OP), calculated as oxygen consumption (V̇O

CONCLUSIONS: A smaller RV was associated with worse exercise performance, indicating exercise intolerance is independent of RV dilatation in young rTOF with PI and represents a unique pathological entity responsible for reduced exercise performance.
