Effects of dyadic coping on post-traumatic growth in patients and couples with breast cancer: an analysis based on the actor-partner interdependence model.

Purpose: Based on a dyadic perspective, the interaction between two variables of dyadic coping and post-traumatic growth in couples with breast cancer is explored, which facilitates an empirical basis for healthcare professionals to develop an intervention program to improve psychological care and quality of life for breast cancer couples.

Methods: Two hundred ten pairs of breast cancer couples attending the department of surgical oncology of a hospital affiliated with Bengbu Medical University from July to December 2023 were surveyed through a cross-sectional method. Both breast cancer couples' completed questionnaire data were investigated using the General Information Questionnaire, the Dyadic Coping Inventory, and the Post-Traumatic Growth Inventory.

QTL Identification for Stem Fiber, Strength and Rot Resistance in a DH Population from an Alien Introgression of .

Stem fiber, stem strength and stem-rot resistance are important agronomic traits in . To understand the molecular mechanism that controls the stem-related traits, we investigated the stem lignin (ADL), cellulose (Cel), hemicellulose (Hem) content, S/G monolignol ratio (SG), stem breaking force (BF), breaking strength (F) and resistance (SSR). Each trait was significantly positively or negatively correlated with more than three of the other six traits.

Global gene expression perturbations in rapeseed due to the introduction of alien radish chromosomes.

The aneuploidy chromosome addition lines with individual chromosomes of one species into the whole genome of another species developed from interspecific or intergeneric crosses are ideal for studying the gene expression regulation under asymmetrical genome interactions. Here, we chose two rapeseed-radish addition lines (2=40, AACC+2R) with all chromosomes of rapeseed and one pair of radish chromosomes carrying 25S rDNA loci and both 5S and 25S rDNA loci, respectively. Transcriptome sequencing of these two rapeseed-radish addition lines, together with two parents (, 2=38, AACC; Raphanus sativus, 2=18, RR), was performed to assess gene expression changes due to the aneuploidy effect.

Genome-Wide Gene Expressions Respond Differently to A-subgenome Origins in Synthetic Hybrids and Natural Allotetraploid.

The young allotetraploid (2 = 38, AACC) is one of models to study genomic responses to allopolyploidization. The extraction of AA component from natural and then restitution of progenitor should provide a unique opportunity to reveal the genome interplay for gene expressions during the evolution. Herein, hybrids (2 = 19, AC) between the extracted and extant (2 = 20, AA) and the same genotype (2 = 18, CC) were studied by RNA-seq and compared with natural donor, to reveal the gene expression changes from hybridization and domestication and the effects of A genome with different origins.

A Highly Sensitive Fiber-Optic Fabry-Perot Interferometer Based on Internal Reflection Mirrors for Refractive Index Measurement.

In this study, a new type of highly sensitive fiber-optic Fabry-Perot interferometer (FFPI) is proposed with a high sensitivity on a wide refractive index (RI) measurement range based on internal reflection mirrors of micro-cavity. The sensor head consists of a single-mode fiber (SMF) with an open micro-cavity. Since light reflections of gold thin films are not affected by the RI of different measuring mediums, the sensor is designed to improve the fringe visibility of optical interference through sputtering the gold films of various thicknesses on the inner surfaces of the micro-cavity, as a semi-transparent mirror (STM) and a total-reflection mirror (TRM).

Genetic and Epigenetic Changes in Oilseed Rape (Brassica napus L.) Extracted from Intergeneric Allopolyploid and Additions with Orychophragmus.

Allopolyploidization with the merger of the genomes from different species has been shown to be associated with genetic and epigenetic changes. But the maintenance of such alterations related to one parental species after the genome is extracted from the allopolyploid remains to be detected. In this study, the genome of Brassica napus L.

Genome-specific differential gene expressions in resynthesized Brassica allotetraploids from pair-wise crosses of three cultivated diploids revealed by RNA-seq.

Polyploidy is popular for the speciation of angiosperms but the initial stage of allopolyploidization resulting from interspecific hybridization and genome duplication is associated with different extents of changes in genome structure and gene expressions. Herein, the transcriptomes detected by RNA-seq in resynthesized Brassica allotetraploids (Brassica juncea, AABB; B. napus, AACC; B.

Genome-wide gene expression perturbation induced by loss of C2 chromosome in allotetraploid Brassica napus L.

Aneuploidy with loss of entire chromosomes from normal complement disrupts the balanced genome and is tolerable only by polyploidy plants. In this study, the monosomic and nullisomic plants losing one or two copies of C2 chromosome from allotetraploid Brassica napus L. (2n = 38, AACC) were produced and compared for their phenotype and transcriptome.

Genomic change, retrotransposon mobilization and extensive cytosine methylation alteration in Brassica napus introgressions from two intertribal hybridizations.

Hybridization and introgression represent important means for the transfer and/or de novo origination of traits and play an important role in facilitating speciation and plant breeding. Two sets of introgression lines in Brassica napus L. were previously established by its intertribal hybridizations with two wild species and long-term selection.
