Six parameters for the numerical simulations, namely (1) loading boundary condition, (2) geometrical imperfection, (3) friction coefficient, (4) element size, (5) element type, and (6) material nonlinearity model, were examined using a series of finite element analyses.

Levothyroxine Cessation After Thyroid Lobectomy for Papillary Thyroid Cancer Can Be Achieved at the Same Rate as that for Benign Tumors Regardless of the Duration of Thyroid-stimulating Hormone Suppression.

Background/aim: Thyroid lobectomy may cause post-lobectomy hypothyroidism. We investigated the difference in levothyroxine (LT4) supplementation and cessation between patients with benign disease and those with papillary thyroid carcinoma (PTC) and found that the rate of LT4 cessation could be decreased after thyroid-stimulating hormone (TSH) suppression in PTC.

Patients And Methods: We retrospectively reviewed 88 patients with benign tumor and 463 patients with PTC and investigated the risk factors for LT4 supplementation after thyroid lobectomy.

PtrMYB120 functions as a positive regulator of both anthocyanin and lignin biosynthetic pathway in a hybrid poplar.

Both anthocyanins and lignins are essential secondary metabolites in plant growth and development. Their biosynthesis is metabolically interconnected and diverges in the central metabolite 4-coumaroyl CoA of the phenylpropanoid pathway. Considerable progress has been made in understanding transcriptional regulation of genes involved in lignin and anthocyanin synthesis pathways, but the concerted regulation of these pathways is not yet fully understood.

Wood transcriptome analysis of Pinus densiflora identifies genes critical for secondary cell wall formation and NAC transcription factors involved in tracheid formation.

Although conifers have significant ecological and economic value, information on transcriptional regulation of wood formation in conifers is still limited. Here, to gain insight into secondary cell wall (SCW) biosynthesis and tracheid formation in conifers, we performed wood tissue-specific transcriptome analyses of Pinus densiflora (Korean red pine) using RNA sequencing. In addition, to obtain full-length transcriptome information, PacBio single molecule real-time iso-sequencing was carried out using RNAs from 28 tissues of P.

Overexpression of a Poplar RING-H2 Zinc Finger, , Confers Enhanced Drought Tolerance via Reduced Water Loss and Ion Leakage in .
