Article Synopsis
  • D. Don trees, popular in southern China for their ornamental beauty, recently suffered a disease outbreak causing severe dieback symptoms, particularly in Nanjing.
  • An extensive survey of 130 trees revealed that over 90% were affected, showing brown crowns without noticeable bark differences from healthy trees.
  • Fungal isolates were collected from the affected trees, with seven identified as pathogenic and responsible for stem basal canker; one of these isolates represented a new species, with both pathogens being significant threats to D. Don trees.

Aim: To explore the association between () infection status, intestinal metaplasia (IM), and colorectal adenomas.

Methods: We retrospectively reviewed 1641 individuals aged ≥ 40 years who underwent physical examination, laboratory testing, C-urea breath testing, gastroscopy, colonoscopy, and an interview to ascertain baseline characteristics and general state of health. Histopathological results were obtained by gastric and colorectal biopsies.

Article Synopsis
  • * Results indicated that raindrops had little impact on aerosol particles smaller than 2 μm but significantly affected larger particles.
  • * Despite some precipitation reducing PM concentrations, 43.2% of the time, PM levels increased, with rainfall mostly scavenging very small (Aitken mode) and large (coarse mode) particles, leaving accumulation mode particles largely unaffected.

Article Synopsis
  • Aerosol size distributions were measured in Beijing from 2012 to 2014, revealing seasonal and weather-affected characteristics.
  • Aitken mode aerosols peaked in spring, accumulation mode aerosols were highest in spring and winter, and coarse mode aerosols were most concentrated in winter.
  • Diurnal variations were notable for Aitken mode particles due to traffic and photochemical reactions, while accumulation mode aerosols were higher at night in colder months, and coarse mode particles showed little variation throughout the day.

Endoplasmic reticulum (ER) is one of the most important cell organelles in the body, regulating protein synthesis, folding and aggregation. Endoplasmic reticulum stress (ERS) is a particular subcellular pathological process involving an imbalance of homeostasis and ER disorder. In the early stage of ERS, cells show a protective unfolded protein response that changes the cellular transcriptional and translational programs to alleviate the process.

Article Synopsis
  • Systematic measurements of atmospheric visibility and various pollutants were conducted in Beijing from 2013 to 2014 to study the atmospheric extinction coefficient.
  • The research compared different models for aerosol light scattering and analyzed factors influencing the extinction coefficient, particularly focusing on seasonal changes and pollution levels.
  • Findings revealed that aerosol scattering makes up over 94% of light extinction, with significant increases during summer and autumn due to high humidity, leading to enhanced aerosol scattering.
