Measurement of carbon dynamics of soybean (Glycine max L.) ecosystems outside Corn Belt of the United States (U.S.) is lacking. This study examines the seasonal variability of net ecosystem CO2 exchange (NEE) and its components (gross primary production, GPP and ecosystem respiration, ER), and relevant controlling environmental factors between rainfed (El Reno, Oklahoma) and irrigated (Stoneville, Mississippi) soybean fields in the southern U.S. during the 2016 growing season. Grain yield was about 1.6tha(-1) for rainfed soybean and 4...

Mature B cell pools retain a substantial proportion of polyreactive and self-reactive clonotypes, suggesting that activation checkpoints exist to reduce the initiation of autoreactive B cell responses. Here, we have described a relationship among the B cell receptor (BCR), TLR9, and cytokine signals that regulate B cell responses to DNA-containing antigens. In both mouse and human B cells, BCR ligands that deliver a TLR9 agonist induce an initial proliferative burst that is followed by apoptotic death. The latter mechanism involves p38-dependent G1 cell-cycle arrest and subsequent intrinsic mitochondrial apoptosis and is shared by all preimmune murine B cell subsets and CD27- human B cells...

Despite the availability of a number of different classes of therapeutic agents with proven efficacy in heart failure, the clinical course of heart failure patients is characterized by a reduction in life expectancy, a progressive decline in health-related quality of life and functional status, as well as a high risk of hospitalization. New approaches are needed to address the unmet medical needs of this patient population. The European Medicines Agency (EMA) is undertaking a revision of its Guideline on Clinical Investigation of Medicinal Products for the Treatment of Chronic Heart Failure...

BACKGROUND: The World Health Organization (WHO) recommendation on universal coverage has been implemented in Indonesia as Jaminan Kesehatan Nasional (JKN). It was designed to provide people with equitable and high-quality health care by strengthening primary care as the gate-keeper to hospitals. However, during its first year of implementation, recruitment of JKN members was slow, and the referral rates from primary to secondary care remained high. Little is known about how the public views the introduction of JKN or the factors that influence their decision to enroll in JKN...

BACKGROUND & AIMS: Hepatitis C virus (HCV) is highly variable with 7 genotypes and 67 subtypes characterized to date. HCV genotype (GT) and subtype, and presence of resistance associated substitutions (RASs) represent the key viral determinants for the selection of direct-acting antiviral (DAA) treatment regimens. However, currently available HCV genotyping assays have limitations in differentiating between HCV subtypes and RAS prevalence in different subtypes is largely undefined. METHODS: In this study, we compared HCV GT and subtypes with INNO-LiPA 2...

Interactions between short protein segments and phospholipid bilayers dictate fundamental aspects of cellular activity and have important applications in biotechnology. Yet, a lack of suitable methodology for directly probing these interactions has hindered mechanistic understanding. We developed a precision atomic force microscope (AFM)-based single-molecule force spectroscopy assay and probed partitioning into lipid bilayers by measuring the mechanical force experienced by a peptide. Protein segments were constructed from the peripheral membrane protein SecA, a key ATPase in bacterial secretion...

The cause of diabetic macular edema (DME) is due to prolonged and uncontrolled diabetes mellitus (DM) which affects the vision of diabetic subjects. DME is graded based on the exudate location from the macula. It is clinically diagnosed using fundus images which is tedious and time-consuming. Regular eye screening and subsequent treatment may prevent the vision loss. Hence, in this work, a hybrid system based on Radon transform (RT), discrete wavelet transform (DWT) and discrete cosine transform (DCT) are proposed for an automated detection of DME...

BACKGROUND CONTEXT: Cervical disc arthroplasty (CDA) is an emerging technique for the treatment of cervical degenerative disease. Multiple studies have investigated the outcomes of CDA, particularly in comparison to cervical arthrodesis techniques such as anterior cervical discectomy and fusion (ACDF). As many entities have financial interests in CDA implants, it is imperative to consider the influence of conflicts of interest on the results of studies investigating the efficacy of CDA...

Phase-separated multi-molecular assemblies provide a general regulatory mechanism to compartmentalize biochemical reactions within cells. We propose that a phase separation model explains established and recently described features of transcriptional control. These features include the formation of super-enhancers, the sensitivity of super-enhancers to perturbation, the transcriptional bursting patterns of enhancers, and the ability of an enhancer to produce simultaneous activation at multiple genes. This model provides a conceptual framework to further explore principles of gene control in mammals...

Previously, we reported a genome wide association study (GWAS) that had shown association of a region between 11.8 and 13.6 Mbp on chromosome 9 with ascites phenotype in broilers. We had used microsatellite loci to demonstrate an association of particular genotypes for this region with ascites in experimental ascites lines and commercial broiler breeder lines. We identified two potential candidate genes, AGTR1 and UTS2D, within that chromosomal region for mediating the quantitative effect. We have now extended our analysis using SNPs for these genes to assess association with resistance or susceptibility to ascites in these same broiler lines...

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder of the hematopoietic stem cells, characterized at the molecular level by the bcr/abl gene rearrangement. Even though targeting the fusion gene product Bcr-Abl protein is a successful strategy, development of drug resistance and drug intolerance are currently the limitations for Bcr-Abl targeted CML therapy. With an aim to develop natural Bcr-Abl inhibitors, we performed virtual screening (VS) of ZINC natural compound database by docking with Abl kinase using Glide software...

Centrosomes, or spindle pole bodies (SPBs) in yeast, are vital mechanical hubs that maintain load-bearing attachments to microtubules during mitotic spindle assembly, spindle positioning, and chromosome segregation. However, the strength of microtubule-centrosome attachments is unknown, and the possibility that mechanical force might regulate centrosome function has scarcely been explored. To uncover how centrosomes sustain and regulate force, we purified SPBs from budding yeast and used laser trapping to manipulate single attached microtubules in vitro Our experiments reveal that SPB-microtubule attachments are extraordinarily strong, rupturing at forces about 4-fold higher than kinetochore attachments under identical loading conditions...
