Efficacy of 0.2% povidone‐iodine and 0.1% polyhexamethylene biguanide as preoperative antiseptics in equine ophthalmic procedures

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 438-447, March 2025.
Abstract Objective This retrospective study evaluates the efficacy of povidone‐iodine (PI) and polyhexamethylene biguanide (PHMB) as preoperative antiseptics in equine ophthalmic procedures. Animals Studied Horses that underwent routine ophthalmic surgery and procedures.

High‐throughput classification and quantification of skinning phenotype in sweet potatoes

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Sweet potatoes (SPs) (Ipomoea batatas) are a valued crop for their color, flavor, and nutrition. Harvesting is labor‐intensive, requiring hand‐picking to maintain skin quality. Mechanical harvesting often causes skin damage, known as “skinning,” where skin is cut, scraped, or torn, leading to lower quality during packing.

BK and JC virus: A review

Journal of Infection, 2014
Polyomaviruses are ubiquitous, species-specific viruses belonging to the family Papovaviridae. The two most commonly known human polyomaviruses, BK virus and JC virus were first described in the 1970s. Newer human polyomaviruses, namely KI polyoma virus, WU polyoma virus and Merkel cell polyoma virus were identified in the last five years.

Undetectable JC virus CSF PCR in patients with JC virus-induced progressive multifocal leukoencephalopathy

Journal of NeuroVirology, 2023
The diagnosis of progressive multifocal leukoencephalopathy (PML) is based on a combination of clinical, radiographic, and laboratory findings. However, negative JC polyomavirus (JCPyV) PCR in CSF does not always rule out JCPyV-related PML. In this narrative review, we sought to examine the characteristic of biopsy-proven PML in patients with ...

Role of the Environment in the Transmission of JC Virus

Journal of Neurovirology, 2003
JC virus is etiologically associated with a fatal demyelinating disease known as PML. JCV produces persistent infections in the kidney and is excreted in the urine of healthy individuals and in the urine of PML patients. The characteristics of the JCV excreted in the environment have been studied by analyzing sewage samples from divergent geographical ...

Structure and function of JC virus T' proteins [PDF]

open access: possibleJournal of Neurovirology, 2001
The initial sequence analyses of the primate polyomavirus genomes conŽrmed the identity of 2 proteins, the large and small tumor antigens (TAg and tAg), encoded by the viral early regions. These multifunctional regulatory proteins are translated from transcripts generated by alternative splicing of the viral early mRNA. TAg, and to a lesser extent tAg,

JC virus and multiple sclerosis: a refutation?

Acta Neurologica Scandinavica, 2009
Polyomavirus JC (JCV) has been implicated in the etiology of multiple sclerosis (MS), because it causes progressive multifocal leukoencephalopathy (PML), a multifocal demyelinating disease with many microscopical similarities to MS. During childhood, the virus establishes a latent infection in the kidneys, which can be reactivated in immunocompromised ...

JC virus: a biomarker for colorectal cancer?

Medical Hypotheses, 2002
Chromosomal instability (CIN) is present in most colorectal cancers, though the mechanism for these genetic aberrations is unclear. An explanation may lie in the possible link between JC virus (JCV) Mad-1 strain, found in colorectal cancers, and aneuploid neoplasia.

Assessment of JC Polyoma Virus in Colon Neoplasms

Diseases of the Colon & Rectum, 2005
Research data have recently emphasized an intriguing association of JC polyoma virus with colon carcinogenesis. Tumorigenicity of JC virus is attributed to the T-antigen of its Mad-1 variant. Controversy arose when another research group did not confirm this association.

JC virus in human glial-derived tumors

Human Pathology, 2000
To investigate the presence and the role of polyomaviruses JC (JCV), BK (BKV), and the simian polyomavirus (SV40) in human brain tumors, samples from 25 glial-derived tumors (10 astrocytomas, 5 ependymomas, 5 oligodendrogliomas, and 5 glioblastomas) were examined by means of molecular biology and immunohistochemistry.
