Obstacles in quantifying A-to-I RNA editing by Sanger sequencing.

Adenosine-to-Inosine (A-to-I) RNA editing is the most prevalent type of RNA editing, in which adenosine within a completely or largely double-stranded RNA (dsRNA) is converted to inosine by deamination. RNA editing was shown to be involved in many neurological diseases and cancer; therefore, detection of A-to-I RNA editing and quantitation of editing levels are necessary for both basic and clinical biomedical research. While high-throughput sequencing (HTS) is widely used for global detection of editing events, Sanger sequencing is the method of choice for precise characterization of editing site clusters (hyper-editing) and for comparing levels of editing at a particular site under different environmental conditions, developmental stages, genetic backgrounds, or disease states.

Exploring factors behind patient non-adherence to intravitreal anti-VEGF injections in macular diseases.

Introduction: In recent years, intravitreal injections (IVT) of vascular endothelial growth factor (VEGF) inhibitors have become the standard of care for several macular disorders. Frequently, the therapeutic course requires numerous injections, posing a burden on patients. Non-adherence to treatment may result in reduced visual outcomes, therefore understanding and addressing the underlying causes is imperative.

Total shoulder arthroplasty in a patient with osteopetrosis: A case report.

Osteopetrosis is a rare genetic disorder that leads to increased bone density and fragility due to dysfunctional osteoclasts, which can result in narrowed bone marrow spaces, hardened cartilage, and brittle bones. This condition frequently coexists with osteoarthritis among affected individuals. When osteoarthritis results in significant pain and impairs function, surgical interventions such as total joint arthroplasty may be recommended, although these procedures come with a unique set of surgical and recovery-related hurdles.

GENA-LM: a family of open-source foundational DNA language models for long sequences.

Recent advancements in genomics, propelled by artificial intelligence, have unlocked unprecedented capabilities in interpreting genomic sequences, mitigating the need for exhaustive experimental analysis of complex, intertwined molecular processes inherent in DNA function. A significant challenge, however, resides in accurately decoding genomic sequences, which inherently involves comprehending rich contextual information dispersed across thousands of nucleotides. To address this need, we introduce GENA language model (GENA-LM), a suite of transformer-based foundational DNA language models capable of handling input lengths up to 36 000 base pairs.

Single-molecule toxicogenomics: Optical genome mapping of DNA-damage in nanochannel arrays.

Quantitative genomic mapping of DNA damage may provide insights into the underlying mechanisms of damage and repair. Sequencing based approaches are bound to the limitations of PCR amplification bias and read length which hamper both the accurate quantitation of damage events and the ability to map them to structurally complex genomic regions. Optical Genome mapping in arrays of parallel nanochannels allows physical extension and genetic profiling of millions of long genomic DNA fragments, and has matured to clinical utility for characterization of complex structural aberrations in cancer genomes.

Hematuria in the ER patient: optimizing detection of upper tract urothelial cancer - A pictorial essay.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.
