Sequences (MRS) distantly related to mouse mammary tumor virus (MMTV) were found in genomes of a wide range of mammalian species using blot hybridization. The number of MRS copies and the degree of their homology with the hybridization probe varied and did not correlate with the taxonomic position of the species. Nevertheless, within a genus the set of MRS was species specific and reflected the taxonomic relation between the species. MRS were also found in avian genomes and the degree of their homology did not correlate with the taxonomic position of the species either. The origin and distribution of MRS is discussed on the basis of the authors' and published data.

Study Objectives: Insomnia with objective short sleep duration is associated with increased hypertension risk. We aimed to explore the mechanism underlying the association between objective short sleep duration and hypertension in patients with chronic insomnia disorder (CID) by multi-omics.
Methods: CID was defined according to International Classification of Sleep Disorders-3, and objective short sleep was based on the median value of total sleep time of the overall subjects during an overnight polysomnography.

Brain network dynamics have been extensively explored in patients with subjective cognitive decline (SCD). However, these studies are susceptible to individual differences, scanning parameters, and other confounding factors. Therefore, how to reveal subtle SCD-related subtle changes remains unclear.

Purpose: This study aims to propose a classification system to more accurately understand the features and nature of different CPs, to investigate the correlation between different topographies of CPs and their surgical outcomes.
Methods: A retrospective analysis was conducted on 91 surgically resected CPs. They were categorized into six types based on their location and origin.

Purpose: The study aimed to examine the usefulness of a novel density measurement drill for evaluating cancellous bone density by examining the correlation between computed tomography (CT)-based Misch bone density classification and drilling torque value.
Methods: Bovine ribs were used as the drilling sites for implant placement. Multidetector CT (MDCT) was performed after contrast materials were attached to the drilling sites.

Corals associate with a diverse community of prokaryotic symbionts that provide nutrition, antioxidants and other protective compounds to their host. However, the influence of microbes on coral thermotolerance remains understudied. Here, we examined the prokaryotic microbial communities associated with colonies of Acropora cf.
