Abstract The chemical compositions of tea (Camellia sinensis) are affected by numerous factors, such as cultivar, climate, leaf position, and cultivation pattern. However, under the same conditions, the chemical compositions are mainly determined by varieties. Therefore, we investigated the genetic diversity of chemical compositions of tea tree resources in China to screen excellent germplasm resources. Three chemical compositions index (including chlorophyll index, flavonoid index, and anthocyanin index) and the nitrogen balance index of tea leaves were measured in 102 tea germplasms planted in Chinese Tea Plants Improved Variety Germplasm Resources Nursery (CTPIVGRN) by Dualex on April 15 2019. Results showed that… More >

Abstract Bamboos are one of the most beautiful and useful plants on Earth. The genetic background and population structure of bamboos are well known, which helps accelerate the process of artificial domestication of bamboo. Partial sequences of six genes involved in nitrogen use efficiency in 32 different bamboo species were analyzed for occurrence of single nucleotide polymorphisms (SNPs). The nucleotide diversity θw and total nucleotide polymorphisms π_T of the sequenced DNA regions was 0.05137 and 0.03332, respectively. Both πnonsyn /πsyn and Ka/Ks values were <1. The nucleotide sequences of these six genes were inferred to be relatively conserved, and the haplotype… More >

Abstract Soybean (Glycine max (L.) Merr) is an agro-economic crop growing across the world to cater nutrition for both human and animal feed due to the high oil and protein content in its edible seeds. The genes and QTLs associated with important agronomic traits in this crop have already been identified and validated for soybean cyst nematode (SCN), Phytophthora root and stem rot, Pythium root rot and aphid resistance, seed quality, nutrient values, and also employed for genetic improvement in soybean. In the last decade, micro RNAs (miRNAs) have been considered the effector molecules, so the detection and characterization of novel… More >

Abstract The emerging contaminants (ECs) are organic compounds including pharmaceuticals. These products are consumed in large quantities, favoring their continuous entrance to the environment and affecting the health of living beings. Diclofenac is a non-steroidal anti-inflammatory drug with analgesic properties of prolonged release. It is the commonest postoperative analgesic, and it is highly consumed without prescription. In recent years, the capability of microalgae to remove pharmaceuticals in water has been tested as a promising tool. In this work, the removal efficiency of diclofenac (16 µg/mL) by the microalga Nannochloropsis oculata CCAP 186/7 was evaluated. The major nutrient concentrations in Bold’s Basal… More >

Abstract Based on the recent development of renewable energy utilization technology, in addition to centralized photovoltaic power plants, distributed photovoltaic power generation systems represented by building-integrated photovoltaic systems are frequently employed for power supply. Therefore, in the architectural design, the double-glass photovoltaic module used in the integrated photovoltaic building system puts forward a higher load-bearing capacity requirement and the corresponding simplified method of carrying capacity check. This article focuses on the simplified method of checking the bearing capacity of the four-sided simply supported double-glass photovoltaic module. First, the principle of equivalent stiffness is used to calculate the effective thickness. Then, the… More >

Abstract The concentration of cell-free fetal DNA fragments should be detected before noninvasive prenatal testing (NIPT). The fetal DNA molecules have significant clinical potential in determining the overall performance of NIPT and clinical interpretation. It is important to measure fetal DNA fraction before NIPT. However, there is still little research on how to calculate the concentration of female fetuses. Two estimation approaches were proposed to calculate fetal DNA fraction, including the fragments size-based approach, aneuploid-based approach, which are all approaches based on chromosome segments. Based on high-throughput sequencing data, two approaches to calculate the DNA fraction of male fetuses were tested… More >

Abstract We here report the de novo transcriptome assembly and functional annotation of Eusirus cf. giganteus clade g3, providing the first database of expressed sequences from this giant Antarctic amphipod. RNA-sequencing, carried out on the whole body of a single juvenile individual likely undergoing molting, revealed the dominant expression of hemocyanins. The mRNAs encoding these oxygen-binding proteins cumulatively accounted for about 40% of the total transcriptional effort, highlighting the key biological importance of high hemocyanin production in this Antarctic amphipod species. We speculate that this observation may mirror a strategy previously described in Antarctic cephalopods, which compensates for the decreased ability… More >

Abstract Circular RNAs (circRNAs) are a novel class of non-coding RNA that have recently shown to have huge capabilities in the regulation of gene expression at the posttranscriptional level. Growing evidence has indicated that circRNAs could serve as competing endogenous RNAs (ceRNAs) to sponge microRNAs (miRNAs) and suppress functions of targeted miRNAs. Osteosarcoma (OS) is the most common malignant primary bone cancer. Hsa_circ_0002137 is upregulated in OS. However, the role of hsa_circ_0002137 in OS remains unclear. Using miRNA pull-down assay, we showed that cir_0002137 sponged hsa-miR-1246, and BCL2 apoptosis regulator (BCL2) mRNA was a potential target of hsa-miR-1246 in human osteosarcoma… More >

Abstract Myocytes power the movement of all organs in the body. Damage to and degradation of myocytes causes hypokinesia and muscle-related degenerative diseases. Apigenin, a kind of flavone, is being used to treat many disorders. It exerts a host of different pharmacological activities, such as anti-inflammatory, anti-mutagenic, cardioprotective, and antioxidant effects. Accordingly, apigenin is considered a promising candidate for myocyte protection. In this review, we introduced the characteristics of apigenin. The means of apigenin protection of myocytes as well as the mechanism were summarized and discussed. The protective effects can be classified into proliferation-promoting, anti-inflammatory, atrophy-preventing, metabolism-increasing, and antioxidative effects. Additionally,… More >

Abstract Gastric cancer (GC) is one of the most common cancer worldwide. Although emerging evidence indicates that autophagy-related long non-coding RNA (lncRNA) plays an important role in the progression of GC, the prognosis of GC based on autophagy is still deficient. The Cancer Genome of Atlas stomach adenocarcinoma (TCGA-STAD) dataset was downloaded and separated into a training set and a testing set randomly. Then, 24 autophagy-related lncRNAs were found strongly associated with the survival of the TCGA-STAD dataset. 11 lncRNAs were selected to build the risk score model through the least absolute shrinkage and selection operator (LASSO) regression. Every patient got… More >
