Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Hydrophobic Modification of Wood Using Tetramethylcyclotetrasiloxane

Polymers, 2022
Hydrophobic surfaces have aroused considerable attention because of their extensive potential applications. In this work, we developed a facile strategy for fabricating hydrophobic and anti-fouling surfaces on wood substrates. The modification was accomplished simply by immerging wood into the tetramethylcyclotetrasiloxane (D4H) modifier solution for 5

Thermal Modification Intensity of Heat-treated Poplar Wood Part 1: Characterization and Predication of Surface Layer

Drvna Industrija, 2023
Wood heat treatment is an environmentally friendly method, and the heat-treated wood properties are closely related to thermal modification intensity. This study focuses on the 0-3 mm surface layer (SL) of poplar wood heat treated at 160~220 °C.

Influence of microwave plasticization, areal compression and high-temperature treatment on equilibrum moisture content and shrinkage of Spruce (Picea abies (L.) Karst.)

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
The wood is heterogenous material compound from substance of cell walls and air. It is colloidal ca­pil­la­ry-cellular material with ortogonal anisotropy (Babiak, 1976). The wood has possibility to bound liquids and gases into the structure.

Influence of silicone oil thermal modification on mechanical properties of masson pine wood

Maderas: Ciencia y Tecnología, 2021
In this study, the effect of silicone oil thermal modification at different treatment temperatures (150 ºC, 180 ºC and 210 ºC for 2 h and 4 h.) on the mechanical properties of masson pine (Pinus massoniana L.) wood was investigated. The density, modulus
