BACKGROUND: Pectobacterium carotovorum subsp. carotovorum (Pcc) is a soft rot bacterium which upon entry into the plant macerates plant tissues by producing plant cell wall degrading enzymes. It has a wide host range which includes carrot, potato, tomato, leafy greens, squash and other cucurbits, onion, green peppers and cassava. During plant-microbe interactions, one of the ways of plant response to pathogen infection is through the small RNA silencing mechanism. Under pathogen attack the plant utilizes microRNAs to regulate gene expression by means of mediating gene silencing at transcriptional and post-transcriptional level...

BACKGROUND: Reference intervals are vital for interpretation of laboratory results. Many existing reference intervals for cerebrospinal fluid total protein (CSF-TP) are derived from old literature because of the invasive nature of sampling. The objective of this study was to determine reference intervals for CSF-TP using available patient data. METHODS: Twenty years of hospital database information was mined for previously reported CSF-TP results. Associated demographic, laboratory, and clinical diagnosis (International Classification of Diseases 9/10 codes) details were extracted...

The first generation of immune checkpoint inhibitors (anti-CTLA-4 and anti-PD-1/PD-L1) targeted natural immune homeostasis pathways, co-opted by cancers, to drive anti-tumor immune responses. These agents led to unprecedented results in patients with previously incurable metastatic disease and may become first-line therapies for some advanced cancers. However, these agents are efficacious in only a minority of patients. Newer strategies are becoming available that target additional immunomodulatory mechanisms to activate patients' own anti-tumor immune responses...

Hoxa1 has important functional roles in neural crest specification, hindbrain patterning and heart and ear development, yet the enhancers and genes that are targeted by Hoxa1 are largely unknown. In this study, we performed a comprehensive analysis of Hoxa1 target genes using genome-wide Hoxa1 binding data in mouse ES cells differentiated with retinoic acid (RA) into neural fates in combination with differential gene expression analysis in Hoxa1 gain- and loss-of-function mouse and zebrafish embryos. Our analyses reveal that Hoxa1-bound regions show epigenetic marks of enhancers, occupancy of Hox cofactors and differential expression of nearby genes, suggesting that these regions are enriched for enhancers...

Water utilities face different challenges that may force them to seek prioritized objectives. When doing so, particular projects may have to be developed, being important to understand their impact on water tariffs, and thus, on customers. Such consequences may bear an increased relevance in cases stressed with, e.g., resource scarcity, poverty, and the need for infrastructure investments. The resulting cost and revenue variability demand a comprehensive study. If the first may require a stochastic modeling (in major cost components) in order to consider its inherent uncertainty, the second needs to be modeled following context-specific objectives set by the relevant stakeholders...

Central nervous system (CNS) involvement in Langerhans cell histiocytosis (LCH) can include mass lesions of the hypothalamic pituitary axis, choroid plexus, cerebrum, and cerebellum or magnetic resonance imaging (MRI) signal abnormalities of the cerebellum, pons, and basal ganglia. The term neurodegenerative (ND) CNS-LCH has been given to the MRI signal abnormalities and neurologic dysfunction, although initially patients may have no clinical symptoms. Standardized evaluations to better understand the natural history and response to therapy are needed...

V-domain immunoglobulin suppressor of T cell activation (VISTA) is a recently discovered immune checkpoint ligand that functions to suppress T cell activity. The therapeutic potential of activating this immune checkpoint pathway to reduce inflammatory responses remains untapped, largely due to the inability to derive agonists targeting its unknown receptor. A dimeric construct of the IgV domain of VISTA (VISTA-Fc) was shown to suppress the activation of T cells in vitro. However, this effect required its immobilization on a solid surface, suggesting that VISTA-Fc may display limited efficacy as a VISTA-receptor agonist in vivo...

Interactions between protein ligands and receptors play crucial roles in cell-cell signalling. Most of the human cell surface receptors have been identified in the post-Human Genome Project era but many of their corresponding ligands remain unknown. To facilitate the pairing of orphan receptors, 2762 sequences encoding all human single-pass transmembrane proteins were selected for inclusion into a mammalian-cell expression library. This expression library, consisting of all the individual extracellular domains (ECDs), was constructed as a Fab fusion for each protein...

RIASSUNTO. La folie à deux (FAD) è una condizione clinica osservata per la prima volta nella storia da Lasègue e Falret nel XIX secolo. Descrissero una rara circostanza nella quale due o più persone si ritrovarono a condividere idee deliranti gli uni dagli altri. Oggigiorno tracce di questa diagnosi del passato e del suo substrato psicopatologico si ritrovano nell'ICD-10, in cui la FAD viene codificata come "Disturbo Psicotico Condiviso". Considerando la scarsa letteratura in merito e la mancanza di una ben precisa definizione sintomatologica, risulta difficile circoscrivere i confini clinici della FAD...

Oxygen-based electrophiles have emerged as some of the most valuable cross-coupling partners in organic synthesis due to several major strategic and environmental benefits such as abundance and potential to avoid toxic halide waste. In this context, iron-catalyzed C-O activation/cross-coupling holds particular promise to achieve sustainable catalytic protocols due to its natural abundance, inherent low toxicity, an excellent economic and ecological profile. Recently, tremendous progress has been achieved in the development of new methods for functional group tolerant iron-catalyzed cross-coupling reactions by selective C-O cleavage...
