Latitudinal responses of litter decomposition to solar radiation.

Photodegradation driven by solar radiation has been confirmed as an important driving factor for litter decomposition. However, previous single-site studies could not quantify the relative contribution of variation in solar radiation to litter decomposition. To address it, we conducted a field experiment in Heshan National Field Research Station of Forest Ecosystem, Guangdong (Heshan Station, south subtropical climate), Jigongshan Ecological Research Station, Xinyang, Henan (Jigongshan Station, north subtropical climate) and Daqinggou Ecological Research Station, Institute of Applied Ecology, Chinese Academy of Sciences (Daqinggou Station, temperate climate) at intervals of 10 degrees.

Knowledge of Infection Prevention and Attitudes Towards HIV/AIDS Among Chinese Dental Bachelor Interns: An Appeal for Educational Intervention.

Purpose: The present study aimed to assess the current situation of Chinese dental bachelor interns on HIV/AIDS-related knowledge and their attitudes towards HIV/AIDS patients.

Materials And Methods: A cross-sectional, paper-based survey involving 147 dental students from three Chinese dental schools was conducted. Students were recruited to complete the questionnaire regarding their knowledge, awareness and attitudes concerning HIV/AIDS anonymously and voluntarily.

Spinal 5-HT receptor contributes to somatic hyperalgesia induced by sub-chronic stress.

Stress facilitates pain perception and sensitizes pain pathways, but the underlying mechanism is still unclear. The purpose of this study was to investigate whether the activation of 5-hydroxytryptamine (5-HT) subtype-3 receptor in the spinal cord contributes to somatic hyperalgesia induced by repeated three-day forced swim in the estradiol replacement rats after ovariectomy. Somatic sensitivity was assessed by thermal withdrawal latency to radiant heat and mechanical withdrawal threshold to von Frey filaments.

Transcriptome analysis of distinct Lindera glauca tissues revealed the differences in the unigenes related to terpenoid biosynthesis.

The Lindera glauca, an economically and ecologically important tree species, has emerged as a novel potential plant for the intensive studies of essential oil owing to its characteristic aroma and medicinal property in distinct tissues. However, the transcriptome information and molecular research on this species is still unknown to date. To reveal the formation and accumulation mechanism of essential oil in distinct L.
