Development and validation of a 4-gene combination for the prognostication in lung adenocarcinoma patients.

To identify a multi-gene prognostic factor in patients with lung adenocarcinoma (LUAD). Prognosis-related genes were screened in the TCGA-LUAD cohort. Then, patients in this cohort were randomly separated into training set and test set.

Dual-Mode Carbon Aerogel/Iron Rubber Sensor.

Nowadays, the integration of easy production, simple structure, high sensitivity, and multifunctionality is the developing tendency for flexible sensors. Herein we report a facile manufacture of a highly flexible, sensitive, and multifunctional dual-mode sensor with an ultrasimple structure by directly attaching magnetic iron rubber (IR) onto the surface of carbon aerogel (CA) derived from melamine foam. The dual-mode CA/IR sensor exhibits high sensitivities of 5.

[Analysis of the reliability and validity of the simplified Chinese version of the early childhood oral health impact scale].

Purpose: To evaluate the reliability and validity of the Chinese version of The Early Childhood Oral Health Impact Scale.

Methods: Using translation,back -translation, quality evaluation,cross-cultural adaptation and pre-assessment, a Chinese draft scale of the ECOHIS was obtained, then applied to two groups of children. One group was 200 pre-school children which were randomly selected from 2 kindergartens of Chengdu city; the other group was 100 patients aged 3-5 years old from the paediatric dentistry of West China College of Stomatology,Sichuan University.
