Though more costly than petroleum-based fuels and a minor component of overall military fuel sources, biofuels are nonetheless strategically valuable to the military because of intentional reliance on multiple, reliable, secure fuel sources. Significant reduction in oilseed biofuel cost occurs when grown on marginally productive saline-sodic soils plentiful in California's San Joaquin Valley (SJV). The objective is to evaluate the feasibility of oilseed production on marginal soils in the SJV to support a 115 ML yr(-1) biofuel conversion facility...

K+ is widely used by plant cells, whereas Na+ can easily reach toxic levels during plant growth, which typically occurs in saline environments; however, the effects and functions in the chloroplast have been only roughly estimated. Traditionally, the occurrence of ionic fluxes across the chloroplast envelope or the thylakoid membranes has been mostly deduced from physiological measurements or from knowledge of chloroplast metabolism. However, many of the proteins involved in these fluxes have not yet been characterized...

Long non-coding RNAs (lncRNAs) make up a significant portion of non-coding RNAs and are involved in a variety of biological processes. Accurate identification/annotation of lncRNAs is the primary step for gaining deeper insights into their functions. In this study, we report a novel tool, PLncPRO, for prediction of lncRNAs in plants using transcriptome data. PLncPRO is based on machine learning and uses random forest algorithm to classify coding and long non-coding transcripts. PLncPRO has better prediction accuracy as compared to other existing tools and is particularly well-suited for plants...

Emerging evidence supports a key role for the gut microbiota in metabolic diseases, including type 2 diabetes (T2D) and obesity. The dipeptidyl peptidase-4 inhibitor vildagliptin is highly efficacious in treating T2D. However, whether vildagliptin can alter the gut microbiome is still unclear. This study aimed to identify whether vildagliptin modifies the gut microbiota structure during T2D treatment. Diabetic Sprague-Dawley (SD) rats were induced by a high-fat diet and streptozotocin injection (HFD/STZ). Diabetic rats were orally administered a low dose of vildagliptin (LV, 0...

In humans, chronic treatment with selective serotonin reuptake inhibitors (SSRIs) decreases anxiety, unlike acute treatment, which can increase anxiety. Although this biphasic pattern is observed clinically, preclinical demonstrations are rare. In an animal model of antidepressant-induced anxiolytic effects, the novelty-induced hypophagia (NIH) test, a single administration of the SSRI citalopram reportedly elicited anxiogenic-like effects, whereas three administrations over 24 h were sufficient to produce anxiolytic-like effects...

Salt toxicity of agricultural land is a natural phenomenon which is due to agricultural irrigation. This toxicity is harmful to crop productivity via increasing oxidative stress products. In a factorial controlled trial, four levels of lignite-enriched soil (soil lignite content: none, 50, 75 and 100 g kg(-1)) were exposed to three levels of soil salinity (0, 5 and 10 dS m(-1) NaCl). Then reactive oxygen species (ROS) generation (hydrogen peroxide and superoxide radical), lipid peroxidation, antioxidant enzymes activities (peroxidase, catalase and super oxide dismutase), proline, glycine betaine, soluble sugars and soluble protein contents of soybean plants were compared across different lignite concentration and saline toxicity...

Hydraulic fracturing flowback and produced water (FPW) is a wastewater produced during fracturing activities in an operating well which is hyper saline and chemically heterogeneous in nature, containing both anthropogenic and petrogenic chemicals. Determination of FPW associated toxicity to embryonic fish is limited, while investigation into how embryonic exposures may affect later life stages is not yet studied. Zebrafish embryos (24hrs post fertilization) were acutely exposed to 2.5% and 5% FPW fractions for either 24 or 48hrs and returned to freshwater...

BACKGROUND: Pulmonary fibrosis is a life-threatening pathological state of progressive interstitial lung diseases, such as idiopathic pulmonary fibrosis. Myofibroblasts are known to play a critical role in the pathogenesis of pulmonary fibrosis. This study aimed to evaluate the inhibitory effect of a small interfering RNA (siRNA) on a collagen-specific chaperone heat shock protein 47 (HSP47). The siRNA was preferentially delivered to myofibroblasts in a bleomycin (BLM)-induced pulmonary fibrosis rat model using siRNA against HSP47, encapsulated in a vitamin A-coupled liposome (VA-lip-siRNA HSP47)...

Agricultural soils are widely recognized to be capable of carbon sequestration that contributes to mitigating CO2 emissions. To better understand soil organic carbon (SOC) stock dynamics and its driving and controlling factors corresponding with a period of rapid agronomic evolution from the 1980s to the 2010s in the North China Plain (NCP), we collected data from two region-wide soil sampling campaigns (in the 1980s and 2010s) and conducted an analysis of the controlling factors using the random forest model...

Chemical debridement during Regenerative Endodontic procedures is important. Previous research studies have evaluated various antibiotics and their concentrations but none have addressed the concern of delivering these materials. Hence, the purpose of this study was to determine what carrier could be used effectively in a clinical setting. Sixty caries-free maxillary incisors were used and inoculated with Enterococcus faecalis and divided into positive and irrigation controls and experimental groups that had triple antibiotic powder (1:1:1 ciprofloxacin:metronidazole:minocycline) delivered using various carriers: saline, cotton, sponge and methylcellulose...

High altitude hypoxia causes pronounced sympathoexcitation but the underlying mechanisms remain unclear. We tested the hypothesis that intravenous infusion of dopamine to attenuate carotid chemoreceptor responsiveness would reduce muscle sympathetic nerve activity (MSNA) at high altitude. Nine healthy individuals (mean [SD]; 26 [4] yr) were studied at sea level (SL, Zurich) and at high altitude (ALT, 3454 m, 15-17 days after arrival), both while breathing the ambient air and during an acute incremental hypoxia test (8 × 3 min stages, PET O2 90-45 mmHg)...
