Article Synopsis
  • A scale was developed to evaluate preschool teachers' knowledge, attitude, and practice regarding early childhood sex education, based on expert consultations and guidelines.
  • The scale consists of 27 items and has shown strong reliability (Cronbach's α of 0.875) and validity, with good performance across its dimensions.
  • Results indicate that teachers have relatively low levels of knowledge, attitude, and practice in this area, highlighting the need for further training in early childhood sex education.

Objective To understand the current situation and influencing factors of kindergarten teachers' participation in training for preschool sex education in Luzhou city,and provide a basis for improving the sex education literacy of kindergarten teachers in the future. Methods A multi-stage stratified cluster sampling method was adopted,and a questionnaire survey was conducted from December 2021 to January 2022 on the knowledge,attitude,and practice of preschool sex education among all the teachers in 24 kindergartens in Luzhou city. Results Among the 461 teachers,43.

Tea is the world's widely consumed nonalcohol beverage with essential economic and health benefits. Confronted with the increasing large-scale omics-data set particularly the genome sequence released in tea plant, the construction of a comprehensive knowledgebase is urgently needed to facilitate the utilization of these data sets towards molecular breeding. We hereby present the first integrative and specially designed web-accessible database, Tea Plant Information Archive (TPIA; http://tpia.

Article Synopsis
  • Withering is an important step in making tea that helps improve its flavors.
  • Scientists studied how withering affects tea leaves and found many changes in their genes and chemical makeup.
  • They discovered that withering reduces some compounds while increasing others, which helps create the unique flavors we enjoy in different types of tea.

Article Synopsis
  • Tea is a globally popular beverage made from Camellia sinensis, with many wild relatives found in Southwest China.
  • The study used high-throughput sequencing to analyze 15,444 genomic SNPs from various cultivated and wild tea plants, revealing six distinct genetic clusters that correspond to different species and varieties.
  • Findings indicated that cultivated tea plants have higher genetic diversity than wild ones, except for a specific semi-wild variety, and identified genes under selective pressure during tea domestication, contributing to our understanding of tea plant genetics.

C-repeat/dehydration-responsive element binding factors (CBFs) can induce the expression of a suite of cold-responsive genes to increase plant cold tolerance, and inducer of CBF expression 1 (ICE1) is a major activator for CBF. In the present study, we isolated the full-length cDNAs of ICE1 and CBF from Camellia sinensis, designated as CsICE1 and CsCBF1, respectively. The deduced protein CsICE1 contains a highly conserved basic helix-loop-helix (bHLH) domain and C-terminal region of ICE1-like proteins.

Background: Tea is one of the most popular non-alcoholic beverages worldwide. However, the tea plant, Camellia sinensis, is difficult to culture in vitro, to transform, and has a large genome, rendering little genomic information available. Recent advances in large-scale RNA sequencing (RNA-seq) provide a fast, cost-effective, and reliable approach to generate large expression datasets for functional genomic analysis, which is especially suitable for non-model species with un-sequenced genomes.

Objective: To investigate mental health status among middle school students in Wenchuan earthquake region three months after the earthquake.

Methods: 38 classes of 3 middle schools in the disaster region were selected and 1966 students were invited to participate the investigation. The post-traumatic stress disorder (PTSD) checklist-civilian version was used to screen positive PTSD, and the perceived social support scale (PSSS) was used to evaluate the level of perceived social support.

Objective: To explore the relationship between post-traumatic stress disorder (PTSD) and perceived social support (PSS) ability among middle school students in earthquake-stricken areas after the Wenchuan earthquake accident.

Methods: A total of 1966 students from three secondary schools of Wenchuan earthquake-stricken areas were evaluated by PTSD Checklist-Civilian Version (PCL-C) and Perceived Social Support Scale (PSSS).

Results: The overall incidence rate of PTSD was 78.

beta-Glucosidases are important in the formation of floral tea aroma and the development of resistance to pathogens and herbivores in tea plants. A novel beta-glucosidase was purified 117-fold to homogeneity, with a yield of 1.26%, from tea leaves by chilled acetone and ammonium sulfate precipitation, ion exchange chromatography (CM-Sephadex C-50) and fast protein liquid chromatography (FPLC; Superdex 75, Resource S).
