Abstract:
... The tasseled cap transformation (TCT) has been widely used to decompose satellite multi-spectral information into “brightness”, “greenness”, and “wetness” components. Published TCT coefficients for the Landsat sensor series have mainly been derived using top of atmosphere (TOA) reflectance and sparse data sets. Studies to derive TCT coefficients for Landsat surface reflectance (SR) are lacking. In ...
... An eight-week feeding trial was conducted to investigate the effects of chicken gut meal (CGM) in experimental diet on growth performance, plasma biochemical parameters, digestive enzymes activity, intestinal morphologic, muscle composition, and fillet quality of common carp (Cyprinus carpio) (initial body weight: 57.34 ± 0.13 g). Experimental fish were fed with experimental diets containing CGM a ...
... Theoretical evidence is reported for a boron-based K₆Be₂B₆H₆ sandwich cluster, showing a perfectly D₆ₕ B₆H₆ ring, being capped by two tetrahedral K₃Be ligands. Due to the comfortable charge transfer, the sandwich is viable in [K₃Be]³⁺[B₆H₆]⁶⁻[BeK₃]³⁺ ionic complex in nature. The [B₆H₆]⁶⁻ core with 6π aromaticity vividly imitates the benzene (C₆H₆), occurring as a real borozene. In contrast, the te ...

Abstract:
... Globally, one-third of the terrestrial carbon (C) is stored in tropical soils. The warming predicted for this century is expected to increase microbial decomposition in soil and escalate climate change potential by releasing more carbon dioxide (CO₂) into the atmosphere. Understanding the response of soils to warming is a key challenge in predicting future climate change trajectories. Here we exam ...
... Zebrafish irf2bp2a, an ortholog of human IRF2BP2, is specifically expressed in the developing liver at growth stage. As a multi-functional protein, the role of irf2bp2a during hepatogenesis remains unclear. Here we take advantage of an irf2bp2a knockout line to show that the deficiency of irf2bp2a can induce apoptosis of hepatic cells through aberrant p53 activation at the early stage of embryonic ...

Abstract:
... Obesity increases the risk for pathological conditions such as bone loss. On the other hand, physical exercise reduces body adiposity. To test the hypothesis that physical activity improves bone quality, we evaluated voluntary running of defined distances on trabecular and cortical microstructure in mice fed a high-fat diet (HFD). Sedentary mice were fed the standard AIN93G diet or the HFD. Mice f ...
... The Theobroma cacao presents a wide diversity in pod color among different cultivars. Although flavonoid biosynthesis has been studied in many plants, molecular mechanisms governing the diversity of coloration in cacao pods are largely unknown. The flavonoid metabolite profiles and flavonoid biosynthetic gene expression in the pod exocarps of light green pod ‘TAS 410’ (GW), green pod ‘TAS 166’ (GF ...
... Monocyte chemotactic protein-1 (MCP-1) is an adipokine with demonstrated carcinogenic potential. However, there is a lack of evidence whether adipose-produced MCP-1 contributes to breast cancer. We tested the hypothesis that adipose-produced MCP-1 contributes to mammary tumorigenesis in this study. In a breast cancer model of mouse mammary tumor virus-polyomavirus middle T-antigen (MMTV-PyMT), mic ...
... Frozen milk can help producers overcome the seasonality of goat milk production, low goat production and short lactation periods, and avoid discarding milk during some special periods. We investigated effects of combination between freezing (cryogenic refrigerator of −16 to −20°C or ultra-cryogenic refrigerator of −76 to −80°C) and thawing (homeothermy of 20 to 25°C or refrigeration of 2 to 4°C) o ...
... Two series of germacrane-type sesquiterpene lactones were produced by semisynthetic modulation of scaberol C, which was prepared by a standard chemical transformation from an Elephantopus scaber extract. Their inhibition activities against non-small-cell lung cancer cells were screened, and preliminary structure–activity relationships were also established. Among them, monomeric analog 1u and dime ...
... Metal-resistant bacteria can reduce Cd accumulation in plants, but mechanisms underlying this effect are poorly understood. In this study, a highly effective Cd-resistant WRS8 strain was obtained from the rhizoshere soil of Triticum aestivum L. Yangmai-13 and identified as Pseudomonas taiwanensis based on 16S rRNA gene sequence analysis. Strain WRS8 was investigated for its effects on Cd availabil ...

Abstract:
... Metastasis is a devastating aspect of cancer. This study tested the hypothesis that metabolome of metastases differs from that of host organs by using the spontaneous metastasis model of Lewis lung carcinoma (LLC). In a 2 × 2 design, male C57BL/6 mice with or without a subcutaneous LLC inoculation were fed the standard AIN93G diet or a high-fat diet (HFD) for 12 weeks. Lung metastases from injecte ...

Abstract:
... Statistical time series models are increasingly being used to fit medium resolution time series provided by satellite sensors, such as Landsat, for terrestrial monitoring. Cloud and shadows, combined with low satellite repeat cycles, reduce surface observation availability. In addition, only a single year of data can be used where there is high inter-annual variation, for example, over many cropla ...
... Engineering oxygen vacancies (Ovs) in submicron transition metal oxides (TMOs) is a promising way to fabricate high-capacity anodes for lithium-ion batteries (LIBs). Herein, oxygen vacancies activated porous MnO/graphene submicron needle arrays (Ovs-MnO/G NAs) are directly grown on flexible nanoporous Cu–Mn substrate by chemical vapour deposition and hydrogen etching method, and their lithium-ion ...
... Autophagy is a double-edged sword that affects tumor progression by promoting cell survival or death depending on different living contexts. The concrete mechanism by which autophagy modulates the efficacy of radiotherapy for prostate cancer (PC) remains unclear. We exposed RM-1 PC cells to X-ray and explored the role of autophagy in radiation injury. Our results showed increased apoptosis and aut ...

Abstract:
... The countervailing effects of disturbances (e.g., high mortality and enhanced recovery) on population dynamics can occur through demographic processes under rapidly increasing climatic extremes. Across an extreme‐event gradient, we mechanistically demonstrated how dramatic changes in streamflow have affected the population persistence of endangered salmon in monsoonal Taiwan over a three‐decade pe ...
... In the present study, a novel eco-friendly foam (CS-AMP) was successfully prepared by grafting adenosine 5′-monophosphate (AMP) with high biocompatibility onto environment-friendly monomer chitosan (CS). The CS-AMP foam was used to absorb uranium and exhibited an efficient selective adsorption of uranium from aqueous solution and natural seawater. Due to the phosphate group of AMP, the CS-AMP foam ...
... Animals communicate using a diversity of signals produced by a wide array of physical structures. Determining how a signal is produced provides key insights into signal evolution. Here, we examine a complex vibratory mating display produced by male Schizocosa floridana wolf spiders. This display contains three discrete substrate‐borne acoustic components (known as “thumps”, “taps”, and “chirps”), ...

Abstract:
... The absolute radiometric accuracy of the Fengyun 3D advanced Medium Resolution Spectral Imager (FY3D MERSI-II) thermal infrared bands was evaluated using the collected field measurements and atmospheric transfer simulations during 16–22 August 2019 at Lake Qinghai. A thermal infrared radiometer equipped on an unmanned surface vehicle was used to continuously collect the water temperature. Atmosphe ...
... Lung cancer is a lethal malignancy. Plenty of circular RNAs (circRNAs) have been identified to be the vital regulators in lung cancer development. Here, we intended to clarify the functional role of circRNA HIPK3 (circHIPK3, also called hsa_circ_0021593) and its underlying mechanism of action. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was employed to evaluate the level ...
