Molecular Structures of Surfaces and Interfaces of Poly(dimethylsiloxane) Incorporated with Silicone Oils Containing Phenyl Functionality.

Poly(dimethylsiloxane) (PDMS) materials have been widely researched and applied as fouling-release coatings. Incorporation of silicone oils into PDMS has been shown to improve the antifouling properties of PDMS materials. In this research, we applied sum frequency generation (SFG) vibrational spectroscopy to study PDMS materials incorporated with various silicone oils containing phenyl groups in air, water, and protein solutions.

Resistance-Associated Substitution Testing Trends and Impact on HCV Treatment Outcomes in Canada: A CanHepC-CANUHC Analysis.

Resistance-associated substitutions (RASs) are mutations within the hepatitis C (HCV) genome that may influence the likelihood of achieving a sustained virological response (SVR) with direct acting antiviral (DAA) treatment. Clinicians conduct RAS testing to adapt treatment regimens with the intent of improving the likelihood of cure. The Canadian Network Undertaking against Hepatitis C (CANUHC) prospective cohort consists of chronic HCV patients enrolled between 2015 and 2023 across 17 Canadian sites.

Toward expert-level medical question answering with large language models.

Large language models (LLMs) have shown promise in medical question answering, with Med-PaLM being the first to exceed a 'passing' score in United States Medical Licensing Examination style questions. However, challenges remain in long-form medical question answering and handling real-world workflows. Here, we present Med-PaLM 2, which bridges these gaps with a combination of base LLM improvements, medical domain fine-tuning and new strategies for improving reasoning and grounding through ensemble refinement and chain of retrieval.

Identification of the Novel HLA-DRB3*02:185 Allele by Next-Generation Sequencing in a Post-Transplant Renal Patient.

The novel allele HLA-DRB3*02:185 differs from HLA-DRB3*02:02:01:02 by one nucleotide substitution in codon 191 of exon 4.

The Novel HLA-DPB1*1327:01 Allele Identified by Next-Generation Sequencing in a Potential Haematopoietic Stem Cell Donor.

The novel allele HLA-DPB1*1327:01 has a non-synonymous mutation difference compared with HLA-DPB1*04:01:01.
