Horizontal transmission of bacteria to varied hosts can maintain and even expand microbial niches. We previously found that the aphid gut bacterium Serratia symbiotica strain SsMj can be transmitted to ladybird beetles via predation, but whether the predator is a new host, a reservoir or a dead end of this bacterium is unknown. This study aims to provide a clear picture of SsMj circulation from aphids to plants and predators.

Background: Scale insects are worldwide sap-sucking parasites, which can be distinguished into neococcoids and non-neococcoids. Neococcoids are monophyletic with a peculiar reproductive system, paternal genome elimination (PGE). Different with neococcoids, Iceryini, a tribe in non-neococcoids including several damaging pests, has abdominal spiracles, compound eyes in males, relatively abundant wax, unique hermaphrodite system, and specific symbionts.

Article Synopsis
  • The study investigated the use of auditory cortical evoked potentials (ACEP) to assess the auditory capabilities of 126 patients with prelingual deafness who used auditory prostheses between 2012 and 2017.
  • Utilizing the HEARLab™ system, researchers measured the P1-N1-P2 waveform in response to specific sounds, finding higher extraction rates of P1 waves compared to N1 and P2.
  • Results indicated that younger age at the time of using an auditory prosthesis and shorter duration of deafness before its use led to stronger waveforms and longer P1 latencies, highlighting the importance of these factors in auditory assessment.

Objectives: Quite a number of studies on clinical decision support systems (CDSS) have been published in recent years to assess the characteristics and architecture of CDSS and evaluate the effects of CDSS on clinical work. However, until now there have been no relevant studies to investigate the quantity of these, and their contribution to present day thinking. The aim of this study was to explore the areas of theme, and the study design of research on CDSS in literature published in English and Chinese-language journals.

Previous studies have shown that matrix metalloproteinase-9 (MMP-9) and its cognate inhibitor TIMP-1, inflammatory cytokine TNF-α, and the OPG/RANK/RANKL system may each play individual roles in the pathogenesis of osteoporosis in patients with COPD. In the present study, we investigated the interrelationships of these factors in male COPD patients with and without osteoporosis. The serum levels of MMP-9, MMP-9/TIMP-1 ratio, TNF-α, RANKL, OPG, and the RANKL/OPG ratio were higher in COPD patients with osteoporosis than in individuals with normal or low bone mineral density (BMD) (N = 30, all P < 0.

Mulberry is rich in alkaloids, polyphenols, flavonoids, and anthocyanins, which have been suggested to be responsible for health benefits. The concentrations of 1-deoxynojirimycin (DNJ), resveratrol, oxyresveratrol, cyanidin-3-O-beta-glucoside (Cy-3-glu), cyanidin-3-O-beta-rutinoside (Cy-3-rut), and rutin in mulberry juice, fruits, and leaves of 8 species grown in China were examined. It is the first time content determination of DNJ in mulberry juice and oxyresveratrol in mulberry fruits and leaves has been reported.
