The genomic RNA sequences of two genotypes of a brassica-infecting polerovirus from China were determined. Sequence analysis revealed that the virus was closely related to but significantly different from turnip yellows virus (TuYV). This virus and other poleroviruses, including TuYV, had less than 90% amino acid sequence identity in all gene products except the coat protein. Based on the molecular criterion (>10% amino acid sequence difference) for species demarcation in the genus Polerovirus, the virus represents a distinct species for which the name Brassica yellows virus (BrYV) is proposed. Interestingly, there were two genotypes of BrYV, which mainly differed in the 5'-terminal half of the genome.

Background: The bird cherry-oat aphid, Rhopalosiphum padi, is a major pest of agriculture due to its ability to directly damage crops and transmit plant viruses. As industries move away from chemical pest control, there is interest in exploring new options to suppress the impact of this pest.
Results: We describe the production of a transinfected line of R.

Introduction: Opportunistic infections (IO) are infections of microbiota (fungi, viruses, bacteria, or parasites) that generally do not cause disease but turn into pathogens when the body's defense system is compromised. This can be triggered by various factors, one of which is due to a weakened immune system due to Diabetes Mellitus (DM), which increases the occurrence of opportunistic infections, especially in the oral cavity. Fungal (oral candidiasis) and viral (recurrent intraoral herpes) infections can occur in the oral cavity of DM patients.

We report an 18-year-old male who presented with a two-month history of a lesion over his right forearm with a one-week history of sudden increase in size associated with pain. General and systemic examinations were normal. Dermatological examination revealed a single tender, well-defined, pearly white to erythematous, dome-shaped nodule of approximately 6mm x 5mm x 5mm with central umbilication and surrounding erythema.

Objectives: Yellow fever-associated viscerotropic disease (YEL-AVD) is a rare but serious complication arising from administration of live-attenuated yellow fever vaccine to individuals with risk factors such as thymectomy. At present there is no evidence-based treatment, and case fatality rates are high. Sofosbuvir, an NS5B nucleotide inhibitor, has activity against yellow fever virus in vitro and in vivo.

Minimal change disease (MCD) accounts for 10 - 15% of idiopathic nephrotic syndromes in adults. Chronic hepatitis C virus (HCV) infection is rarely ascribed as a cause of MCD and was previously associated with interferon-based therapy. MCD in treatment-naïve chronic HCV infection is extremely rare, with only 3 cases reported in the literature.
