The mechanisms that regulate mitochondrial inheritance are not yet clear, even though it is 100 years since the first description of non-Mendelian genetics. Here, we quantified the copy numbers of mitochondrial DNA (mtDNA) in the gametic cells of angiosperm species. We demonstrate that each egg cell from Arabidopsis thaliana, Antirrhinum majus, and(More)
OBJECTIVES Bonding stability of resinous adhesives to dentin is still problematic and may involve regional variations in dentin composition. This study is to evaluate the effect of dentin depth on the stability of resin-dentin bonds under thermocycling challenge. METHODS Dentin slabs with two flat surfaces parallel to the tooth axis were obtained from(More)
Traditional sound sources and sound detectors are usually independent and discrete in the human hearing range. To minimize the device size and integrate it with wearable electronics, there is an urgent requirement of realizing the functional integration of generating and detecting sound in a single device. Here we show an intelligent laser-induced graphene(More)
OBJECTIVE To examine the effect of body fat mass and fat distribution on pulmonary ventilatory function among the adult females. METHODS Based on the multistage cluster sampling principal, we selected 935 healthy adult females with ages of 19-81 years old in Heilongjiang province to conduct the study. Every 10-years old as a age group. Firstly obtain the(More)
In plants, the copy number of the mitochondrial DNA (mtDNA) can be much lower than the number of mitochondria. The biological significance and regulatory mechanisms of this phenomenon remain poorly understood. Here, using the pollen vegetative cell, we examined the role of the Arabidopsis (Arabidopsis thaliana) mtDNA-binding protein WHIRLY2 (AtWHY2). AtWHY2(More)
The optical properties of barium strontium titanate (Ba0.7Sr0.3TiO3; BST) thin films are described. The BST thin films were epitaxially grown upon MgO (001) substrates by pulsed laser deposition. The crystallographic properties of the BST thin films were examined by x-ray diffraction. The BST thin films were highly optically transparent in the visible(More)
As a gynecological oncology, ovarian cancer has high incidence and mortality. To study the mechanisms of ovarian cancer, the present study analyzed the GSE37582 microarray. GSE37582 was downloaded from Gene Expression Omnibus and included data from 74 ovarian cancer cases and 47 healthy controls. The differentially-expressed genes (DEGs) were screened using(More)
OBJECTIVE To determine the mutation status of K-ras gene in colorectal cancer and analyze the associations between its mutation status and clinicopathological characteristics in colorectal cancer so as to select the patients likely to benefit from a targeted therapy. METHODS A total of 208 colorectal cancer tissue samples were collected from September(More)
A series of dinuclear paddle-wheel like transition metal complexes based on 2-phenylquinoline-4-carboxylic derivative L have been synthesized and characterized by IR, elemental analysis, and X-ray diffraction single crystal analysis. The biological activities of L and its complexes were evaluated as assayed antibacterial activities, including Escherichia(More)
