The complete genomic sequence of an isolate of Tobacco vein banding mosaic virus (TVBMV-YND) from Yunnan, China was determined by sequencing overlapping cDNA fragments obtained by RT-PCR with degenerate and/or specific primers. The genome is composed of 9,570 nucleotides (nt) excluding the 3'-terminal poly (A) tail and contains one single open reading frame of 9,240 nt encoding a large polyprotein of 3,079 amino acids with predicted Mr of 348.6 kDa. Phylogenetic analysis of complete genomic sequences confirmed that TVBMV is a distinct species of the genus Potyvirus. Different parts of TVBMV-YND genome shared different levels of identity with other species of potyviruses, while most parts showed greatest identity with Chilli veinal mottle virus among the potyviruses with available complete genomic sequences. TVBMV-YND had a rare Q/N cleavage site for NIb/CP and uncommon RITC motif in HC-Pro that is crucial for aphid transmission of potyviruses.

Background: The goal of the TREAT-AD Center is to enable drug discovery by developing assays and providing tool compounds for novel and emerging targets. The role of microglia in neuroinflammation has been implicated in the pathogenesis of Alzheimer's disease (AD). Genome-wide association studies, whole genome sequencing, and gene-expression network analyses comparing normal to AD brain have identified risk and protective variants in genes essential to microglial function.

Background: Black Americans (BAs), Hispanics/Latinos (H/Ls), and Africans (As) face a disproportionate burden of aging and Alzheimer's Disease and Related Dementias (AD/ADRD), coupled with underrepresentation in research. Further, researchers also report a lack of compliance on sensitive social determinants of health data for AD/ADRD research. For instance, the PRAPARE tool reports a low completion rate in community and clinical settings.

Background: Majority of people living worldwide live in low- and middle- income countries, including sub-Saharan Africa (SSA). Most cognitive assessment batteries for Alzheimer's Disease(AD), are developed in high income countries (HICs), where most international dementia collaborations and data originate. The African Dementia Consortium (AfDC) is a new scientific collaboration network currently participating in the Recruitment and Retention for Alzheimer's Disease Diversity Genetic Cohorts in the Alzheimer's Disease Sequencing Project (READD-ADSP).

Background: Data-driven criteria for DNA testing were implemented in routine care of Alzheimer Center Amsterdam. We aimed to explore patients' perspectives and considerations regarding their decision to (not) be tested for a monogenic cause of their disease.
Methods: In this mixed method study, 150 of 519 new patients visiting Alzheimer Center Amsterdam who fulfilled the criteria were offered DNA-diagnostics: 86(57%) accepted, 64(43%) did not.

Recent advancements in viral metagenomics and single-virus genomics have improved our ability to obtain the draft genomes of environmental viruses. However, these methods can introduce virus sequence contaminations into viral genomes when short, fragmented partial sequences are present in the assembled contigs. These contaminations can lead to incorrect analyses; however, practical detection tools are lacking.
