Microbial diversity across tea varieties and ecological niches: correlating tea polyphenol contents with stress resistance.

Introduction: Microorganisms exhibit intricate interconnections with tea plants; however, despite the well-established role of microorganisms in crop growth and development, research on microbes within the tea plant remains insufficient, particularly regarding endophytic microorganisms.

Methods: In this study, we collected samples of leaves and rhizosphere soils from 'Zhuyeqi', 'Baojing Huangjincha#1', 'Baiye#1', and 'Jinxuan' varieties planted.

Results: Our analyses revealed significant variations in tea polyphenol contents among tea varieties, particularly with the 'Zhuyeqi' variety exhibiting higher levels of tea polyphenols (>20% contents).

Method for umbilical cord blood-derived basophils by FCM.

We have devised a method for the purification of human basophils from umbilical cord blood by FCM. Umbilical cord blood was collected from six healthy, full-term deliveries. After separation of red blood cells, mononuclear cells were isolated by Ficoll-Hypaque.

[Study on genetic phenotype of asthma through examination of neonates' cord blood cells and interleukin-4].

Objective: To identify the genetic phenotypes of asthma based on the examination of the umbilical cord blood from neonates of the mothers with asthma.

Methods: Umbilical cord blood was collected from 39 asthmatic lying-in women and 46 healthy lying-in women. Eosinophils and basophils absolute counts, total immunoglobulin E, and interleukin (IL)-4 were examined.
