We describe, for the first time, the generation of a viral DNA chip for simultaneous expression measurements of nearly all known open reading frames (ORFs) in the largest member of the herpesvirus family, human cytomegalovirus (HCMV). In this study, an HCMV chip was fabricated and used to characterize the temporal class of viral gene expression. The viral chip is composed of microarrays of viral DNA prepared by robotic deposition of oligonucleotides on glass for ORFs in the HCMV genome. Viral ge

These results suggest that Aβ oligomers are more important than SP for NFT formation and the subsequent neurodegeneration. The domestic cat is a unique animal species that naturally replicates various AD pathologies, especially Aβ oligomer accumulation, NFT formation, and neuronal loss.

The origins and consequences of the extraordinary campaign of Batu Khan, founder of the Golden Horde, and the Mongol Invasion of Europe.

Members of the predatory Myxococcales (myxobacteria) possess large genomes, undergo multicellular development, and produce diverse secondary metabolites, which are being actively prospected for novel drug discovery. To direct such efforts, it is important to understand the relationships between myxobacterial ecology, evolution, taxonomy, and genomic variation. This study investigated the genomes and pan-genomes of organisms within the Myxococcaceae, including the genera Myxococcus and Corallococ

Beta-amyloid (Abeta) is deposited in the parenchyma and blood vessel walls of the senescent brain, and forms lesions termed senile plaques (SPs) and cerebral amyloid angiopathy (CAA). Since in Alzheimer's disease (AD) excessive Abeta is linked to cognitive deterioration, the mechanisms of degradation and clearance of Abeta are now being researched for use in AD therapy. We conducted an immunohistochemical study of the patterns of deposition of two Abeta subtypes (Abeta40 and Abeta42) and the dis

Beta amyloid (Aβ) deposits are seen in aged individuals in many of the mammalian species that possess the same Aβ amino acid sequence as humans. Conversely, neurofibrillary tangles (NFT), the other hallmark lesion of Alzheimer's disease (AD), are extremely rare in these animals. We detected Aβ deposits in the brains of Tsushima leopard cats (Prionailurus bengalensis euptilurus) that live exclusively on Tsushima Island, Japan. Aβ42 was deposited in a granular pattern in the neuropil of the pyrami

Viruses are obligate intracellular parasites, and host cell entry is the first step in the viral life cycle. The SARS-CoV-2 (COVID-19) entry process into susceptible host tissue cells is complex requiring (1) attachment of the virus via the conserved spike (S) protein receptor-binding motif (RBM) to the host cell angiotensin-converting-enzyme 2 (ACE2) receptor, (2) S protein proteolytic processing, and (3) membrane fusion. Spike protein processing occurs at two cleavage sites, i.e., S<sub>1</sub

Senile plaques (SP) are characteristic histopathological manifestations of Alzheimer's disease (AD), but are also found in normal aging (NA). Recent studies have demonstrated that beta amyloid (Aβ) proteins that have been truncated at the N-terminal position 3 (AβpN3) are the predominant component of SP in AD, but not in NA. The present study revealed that AβpN3 was deposited in an age-dependent manner in canine brains. Moreover, AβpN3 was the main component of the SP that developed in very old
