The Structural, Biophysical, and Antigenic Characterization of the Goose Parvovirus Capsid.

Goose parvovirus (GPV) is an etiological agent of Derzsy's disease, afflicting geese and Muscovy ducks worldwide. Its high mortality rate among goslings and ducklings causes large losses to the waterfowl industry. Toward molecular and structural characterization, virus-like particles (VLPs) of GPV were produced, and the capsid structure was determined by cryogenic electron microscopy (cryo-EM) at a resolution of 2.

Maize Streak Virus: Single and Gemini Capsid Architecture.

are ssDNA plant viruses whose control has both economical and agricultural importance. Their capsids assemble into two distinct architectural forms: (i) a T = 1 icosahedral and (ii) a unique twinned quasi-isometric capsid. Described here are the high-resolution structures of both forms of the maize streak virus using cryo-EM.

Physician Assistants in Clinical Endocrinology: Characteristics and Demographics.

Objective: Physician assistants (PAs) are employed in endocrinology, but little is known about their roles and activities. The study aimed to assess PAs' employment characteristics in endocrinology compared to those in all other specialties.

Methods: This descriptive observational study used the 2022 National Commission on Certification of PAs dataset.

Urology outpatient procedures by physician associates and nurse practitioners.

Object: Physician associates (PAs) and nurse practitioners (NPs) are distributed across 70 medical and surgical specialties. A central role is to provide outpatient care. Urology is a significant employer of PAs and NPs, but their scope of practice in the ambulatory setting needs to be better delineated.

Structural characterization and epitope mapping of the AAVX affinity purification ligand.

The application of adeno-associated virus (AAV) vectors in human gene therapies requires reproducible and homogeneous preparations for clinical efficacy and safety. For the AAV production process, often scalable affinity chromatography columns are utilized, such as the POROS CaptureSelect AAVX affinity resin, during downstream processing to ensure highly purified AAV vectors. The AAVX ligand is based on a camelid single-domain antibody capturing a wide range of recombinant AAV capsids.
