Abstract	Low temperature affects plant growth and biomass accumulation in the Qinghai-Tibet Plateau. Bacillus is an important plant growth-promoting rhizobacteria that can promote plant growth directly or indirectly. In this study, bacteria suspensions (cell concentration 1 × 10⁷ cfu/mL) of Bacillus amyloliquefaciens strain GL18 were interacted with Avena sativa seedlings by the root irrigation method under 4°C low-temperature conditions. The biomass accumulation, as well as the physiological and biochemical activities of A. sativa, was detected over 14 days. The results showed that the plant height, root length, fresh and dry weight of A. sativa treated at 4°C with B. amyloliquefaciens by root irrigation increased by 39.28, 32.50, 114.89, and 87.17%, respectively, compared to untreated control. The levels of plant hormones such as abscisic acid, salicylic acid and jasmonic acid were significantly increased, and the activities of superoxide dismutase, peroxidase and catalase increased rapidly and then decreased slowly. The accumulation of hydrogen peroxide and malondialdehyde decreased, and the contents of proline and betaine increased significantly. The genome of GL18 strain was sequenced and its related functional genes were analyzed. The results showed that genome of GL18 strain contained gene clusters encoding proteins related to the synthesis of lipopeptide compounds such as surfactin, iturin, and fengycin, encoding genes involved in 3-indole acetic acid synthesis as well as genes related to the synthesis of plant growth-promoting substances such as siderophore and polyamines. This study provided experimental data and a theoretical basis for the manner in which Bacillus promotes the growth of A. sativa under low-temperature stress.

Abstract	To date, a large number of long non-coding RNAs (lncRNAs) have been recently discovered through functional genomics studies. Importantly, lncRNAs have been shown, in many cases, to function as master regulators for gene expression and thus, they can play a critical role in various biological functions and disease processes including cancer. Although the lncRNA-mediated gene expression involves various mechanisms, such as regulation of transcription, translation, protein modification, and the formation of RNA-protein or protein-protein complexes, in this review, we discuss the latest developments primarily in important cell signaling pathways regulated by lncRNAs in cancer.

Abstract	Mycotoxins are the secondary metabolites of fungi, especially moulds. They have over 300 types and can be easily produced ubiquitously by moulds. Many mycotoxins have been found to be toxic to most farmed animals through the diets. With the globalization of feed ingredient trade and the rapid climate changes, occurrence of mycotoxins become increasingly difficult to be predicted. Thus, the unnoticeable mycotoxin hazards can directly impact the animal production systems. Preventing or minimizing mycotoxins in feed ingredients has become an important topic from the aspect of feed manufacturing industry. The aim of this literature review is to summarize the effective strategies for feed manufacturers to minimize the mycotoxin hazards. Prevention methods, including pre-harvest field management and post-harvest storage management, are still the most effective strategies, since mycotoxins are hardly to be eliminated once they are present in the ingredients. Moreover, mycotoxin reducing effects of several feed manufacturing technologies are also reviewed. In this review, the mycotoxin reducing methods are mainly categorized into 4 methodologies: physical methods, thermal methods, chemical methods, and mycotoxin controlling feed additives. The first three methodologies mainly focus on how to reduce mycotoxins in feed ingredients during processes, while the last one on how to compensate the adverse impacts of mycotoxin-contaminated diets in animal bodies. The results showed that most of the methods reviewed show evident mycotoxin reducing effects, but of different consistencies. On the other hand, many practical factors that can affect the feasibility of each method in practical manufacturing are also discussed in this review. In conclusion, mycotoxin prevention management and the processing stage of cleaning and sorting are still the most efficient strategies to control mycotoxin hazards in current feed manufacturing.

Abstract	Alzheimer's disease (AD) is characterized by the accumulation and deposition of plaques of amyloid-β (Aβ) peptide in the brain. Growing epidemiological and experimental studies have shown that 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) exerts neuroprotection against AD. However, the underlying mechanisms of the action remain unclear. Since Aβ clearance plays a crucial role in Aβ balance in the brain, the aim of the present study was to investigate potential effects of 1,25(OH)2D3 on Aβ1-40, the major soluble oligomeric form of Aβ, clearance via transport across blood-brain barrier (BBB) mediated by low-density lipoprotein receptor-related protein 1 (LRP1) (efflux) and receptor for advanced glycation end products (RAGE) (influx) and peripheral uptake by liver mediated by LRP1. We identified colocalization of LRP1 and RAGE at BBB of mice, established an in vitro BBB model by culturing monolayer mouse brain microvascular endothelial cell line (bEnd.3) cells under hypoxia and observed that 1,25(OH)2D3 treatment enhanced Aβ1-40 efflux across the BBB model and uptake by HepG2 cells. After 1,25(OH)2D3 exposure, LRP1 expression was increased significantly both in vivo and in vitro, and RAGE expression was reduced in the in vitro BBB model but not in microvascular endothelial cells of mice hippocampus. Additionally, we explored the correlation between the corresponding effects of 1,25(OH)2D3 and its nuclear hormone receptor vitamin D receptor (VDR) level. We found that VDR expression was upregulated after 1,25(OH)2D3 treatment both in vivo and in vitro. Collectively, our finding that 1,25(OH)2D3 reduces cerebral Aβ1-40 level by increasing Aβ1-40 brain-to-blood efflux and peripheral uptake through regulating LRP1 and RAGE could shed light on the mechanism of 1,25(OH)2D3 neuroprotection against AD. And the action of 1,25(OH)2D3 might be associated with the VDR pathway.

Abstract	Air-steam gasification of wood residue was explored in a research scale fluidized bed. Catalytic activity of two different kinds of metal catalysts (Ni/CeO2/Al2O3) with various catalyst loadings (20, 30, and 40%) was also investigated at various residence time (20, 40, and 60min) and gasification temperature (750, 825, and 900°C). Non-catalytic experiments were also carried out to determine the optimum conditions for tar cracking and hydrogen/syngas production. Results were revealed that the high temperature (∼900°C) and high catalyst loading (∼40%) are favorable for tar cracking and high-purity hydrogen production. It was also found that for a residence time of 60min, the tar cracking at the presence of Ni/CeO2/Al2O3 is 196% more than that of the case without any catalyst, while at the presence of Ni/Al2O3 it drops to 162%. Finally, the experiments were showed that Ni/CeO2/Al2O3 is more suitable for biomass conversion and hydrogen production than Ni/Al2O3.

Abstract	Although hepatocellular carcinoma (HCC) is usually response to radiation therapy, radioresistance is still the major obstacle that limits the efficacy of radiotherapy for HCC patients. Therefore, further investigation of underlying mechanisms in radioresistant HCC cells is warranted. In this study, we determined the effect of early growth response factor (Egr-1) on irradiation-induced autophagy and radioresistance in HCC cell lines SMMC-7721 and HepG2. We showed that autophagy-related gene 4B (Atg4B) is induced by Egr-1 upon ionizing radiation (IR) in HCC cells. Luciferase reporter assays and chromatin immunoprecipitation (ChIP) revealed that Egr-1 binds to the Atg4B promoter to upregulate its expression in HCC cells. Suppression of Egr-1 function by dominant-negative Egr-1 dampens IR-induced autophagy, cell migration, and increases cell sensitivity to radiotherapy. Together, these results suggest that Egr-1 contributes to HCC radioresistance through directly upregulating target gene Atg4B, which may serve as a protective mechanism by preferential activation of the autophagy.

Abstract	We investigated the spatial patterns of woody species and their relationships with environmental factors in the karst forest of southwest China. Data for 30 woody plant species with an importance value ≥ 5 and 15 environmental factors in 50 quadrats in a forest plot of 200 m × 100 m were used in this study. Two-way indicator species analysis revealed that the forest communities could be divided into 11 vegetation groups and classified into four ecotypes at the third divisional level. Detrended canonical correspondence analysis demonstrated that the variables significantly related to plant patterns were slope position, slope aspect, percentage of outcropping rocks, organic matter, total phosphorus, available nitrogen, and available phosphorus. Variation partitioning revealed that soil properties accounted for 21.0%, topographical features for 13.2%, and unmeasured variables and spatial processes for 47.7% of the variation in the species pattern, which suggest that both the deterministic factors (i.e., related to niche differentiation) and stochastic processes (i.e., related to dispersal limitation) are substantial determinants of the distribution of woody species. Our analysis suggests that picking the right late-succession species for a particular subregion or increasing soil nutrient content in poor habitats would promote species replacement in karst regions.
