The coating of fertilizers with polymers is an acknowledged strategy for controlling the release of nutrients and their availability in soil. However, its effectiveness in the case of soluble phosphate fertilizers is still uncertain, and information is lacking concerning the chemical properties and structures of such coatings. Here, an oil-based hydrophobic polymer system (polyurethane) is proposed for control of the release of phosphorus from diammonium phosphate (DAP) granules. This material was systematically characterized, with evaluation of the delivery mechanism and the availability of phosphate in an acid soil...

BACKGROUND: Alcohol is one of the most commonly used drugs of abuse negatively affecting human health and it is known as a potent teratogen responsible for fetal alcohol syndrome (FAS), which is characterized by cognitive deficits especially pronounced in juveniles but ameliorating in adults. Searching for the potential morphological correlates of these effects, in this study, we compared the course of developmental changes in the morphology of principal hippocampal neurons in fetal-alcohol (A group), intubated control (IC group), and intact control male rats (C group) over a protracted period of the first two postnatal months...

Loss of function mutations of the the ATP-binding cassette-1 (ABCA1) gene are the cause of Tangier disease (TD) in homozygous subjects and familial HDL deficiency (FHD) in heterozygous subjects. These disorders are characterized by reduced plasma HDL-cholesterol and altered efflux of cholesterol from cells. Previous studies in TD patients and ABCA1(-/-) murine models reported defects in platelet count, morphology and function, but the issue is still controversial. We analysed three subjects with low to very low HDL cholesterol levels due to loss of function mutations of the ABCA1 gene...

17α-estradiol is a hormonally inactive isomer of 17β-estradiol, but with similar potency as neuroprotector. However, we have previously reported that pretreatment with high concentration (10 μM) of both estrogens abolishes their neuroprotection in rat cerebellar granule neurons. Here, we have examined neuroprotective properties of 17α-estradiol against glutamate-induced excitotoxicity in chicken cerebellar granule neurons using low (1 nM) and high concentration.17α-Estradiol, 1 nM, was neuroprotective when glutamate was administered after a pretreatment period of 24 h, but not when coadministered with glutamate...

DNA vaccination is one method to protect farmed fish from viral and bacterial diseases. Chimeric antigens encoded by DNA vaccines have been shown to increase the resistance to viral diseases. Here, we sequenced the gene encoding lysosome-associated membrane protein-1 from Japanese flounder, Paralichthys olivaceus, (JfLAMP-1) and assessed its use in a chimeric DNA vaccine fused with the major capsule protein (MCP) from red seabream iridovirus (RSIV). JfLAMP-1 cDNA has a length of 1248 bp encoding 415 aa, which contains transmembrane and cytoplasmic domains...

The cerebellar granule cell (GC) system provides a good model for studying neuronal development. In the external granule layer (EGL), granule cell precursors (GCPs) rapidly and continuously divide to produce numerous GCs as well as GCPs. In some brain regions, the orientation of cell division affects daughter cell fate, thus the direction of GCP division is related to whether it produces a GCP or a GC. Therefore, we tried to characterize the orientation of GCP division from embryonic to postnatal stages and to identify an environmental cue that regulates the orientation...

This study cultivated denitrifying granular sludge in three UASB reactors by the semi-starvation fluctuation C/N ratio strategy (reactor 1 (R1): constant C/N ratio; R2: regular fluctuation C/N ratio; and R3: semi-starvation fluctuation C/N ratio (SSF)). Microbial aggregates appeared in R1, R2 and R3 on days 28, 14 and 6, respectively. Compared with the results in R1 and R2, the guanosine tetraphosphate (ppGpp) concentration was highest, the acyl homoserine lactones (AHLs) concentration quickly reached a certain threshold, and more protein (PN) of extracellular polymeric substances (EPS) secretion resulted in the rapid formation of denitrifying granular sludge in R3...

Indeterminate cell histiocytosis (ICH) is a very rare histiocytic disease. We reported a case of generalized ICH presenting as eroded papules and crusts, accompanied with intermittent fever, pulmonary disorder, lymphadenectasis in the mediastinum, and the retroperitoneum. The histopathology indicated a neoplasm that was composed of small nests of large cells with ample pale cytoplasm. Immunohistochemistry results and the absence of Birbeck granules led us to the diagnosis of ICH. Four months later, the patient died of anemia, ascites, and swelling of the limbs...

Soils contaminated with mercury (Hg) have proved expensive and logistically difficult to remediate. Research continues into finding suitable environmentally-friendly and efficient ways of achieving this end. Bioremediation is an option, which employs the strategies microorganisms have evolved to deal with Hg. One microbial strategy involves uptake and intracellular volatilisation of mercuric ions, which passively diffuse from the cell and back into the atmosphere. In this work, Pseudomonas veronii cells grown to stationary phase were immobilised in a xanthan gum-based biopolymer via encapsulation...

Novel intracytoplasmic inclusions immunoreactive for phosphorylated transactivation response DNA-binding protein 43 (p-TDP43), cystatin C, and transferrin were found in anterior horn cells in a case of sporadic amyotrophic lateral sclerosis (ALS). The patient was a 59-year-old woman, who died of ALS after a clinical course of 8 years. She had been receiving mechanical support for respiration for 6 years and in a "totally locked-in" state for 4 years prior to death. The spinal cord showed severe degeneration involving the anterior and lateral funiculi, whereas the posterior funiculus was preserved...

Most female birds develop only a left ovary, whereas males develop bilateral testes. The mechanism underlying this process is still not completely understood. Here, we provide a comprehensive transcriptional analysis of female chicken gonads and identify novel candidate side-biased genes. RNA-Seq analysis was carried out on total RNA harvested from the left and right gonads on embryonic day 6 (E6), E12, and post-hatching day 1 (D1). By comparing the gene expression profiles between the left and right gonads, 347 differentially expressed genes (DEGs) were obtained on E6, 3730 were obtained on E12, and 2787 were obtained on D1...

Transcriptional output of the Sonic hedgehog morphogenic pathway is orchestrated by three Krüppel family transcription factors, Gli1-3, which undergo extensive post-translational modifications, including ubiquitination and SUMOylation. Here, we report that sentrin-specific peptidase SENP1 is the specific de-SUMOylation enzyme for Gli1. We show that SUMOylation stabilizes Gli1 by competing with ubiquitination at conserved lysine residues, and SUMOylated Gli1 is enriched in the nucleus, suggesting that SUMOylation is a nuclear localization signal for Gli1...

The immunoglobulin superfamily adhesion molecule close homolog of L1 (CHL1) plays important roles during nervous system development. Here, we identified the hedgehog receptor patched-1 (PTCH1) as novel CHL1 binding partner and showed that CHL1 interacts with the first extracellular loop of PTCH1 via its extracellular domain. Co-localization and -immunoprecipitation of CHL1 with PTCH1 suggest an association of CHL1 with this major component of the hedgehog signaling pathway. The trans-interaction of CHL1 with PTCH1 promotes neuronal survival in cultures of dissociated cerebellar granule cells and of organotypic cerebellar slices...

Human neutrophil elastase (HNE) is an important N-glycosylated serine protease in the innate immune system, but the structure and immune-modulating functions of HNE N-glycosylation remain undescribed. Herein, LC-MS/MS-based glycan, glycopeptide and glycoprotein profiling were utilised to first determine the heterogeneous N-glycosylation of HNE purified from neutrophil lysates and then from isolated neutrophil granules of healthy individuals. The spatiotemporal expression of HNE during neutrophil activation and the biological importance of its N-glycosylation were also investigated using immunoblotting, cell surface capture, native MS, receptor interaction, protease inhibition, and bacteria growth assays...
