Abstract As the preferred nitrogen (N) source, ammonium (NH₄⁺ ) contributes to plant growth and development and fruit quality. In plants, NH₄⁺ uptake is facilitated by a family of NH₄⁺ transporters (AMT). However, the molecular mechanisms and functional characteristics of the AMT genes in peach have not been mentioned yet. In this present study, excess NH₄⁺ stress severely hindered shoot growth and root elongation, accompanied with reduced mineral accumulation, decreased leaf chlorophyll concentration, and stunned photosynthetic performance. In addition, we identified 14 putative AMT genes in peach (PpeAMT). Expression analysis showed that PpeAMT genes were differently expressed in peach… More >

Abstract Bayer red mud (BRM) is a kind of industrial solid waste characterized by huge volume and high alkalinity. Its disposal generates serious environmental pollution and occupies a large number of farmland. The utilization and recycling of BRM is currently a crucial issue and needs to be addressed as soon as possible. The chemical composition of BRM is similar to cement clinker. In this study, the feasibility of preparing Belite-ferroaluminate clinker (BFAC) with different BRM was explored. The physical properties, mechanics performance, radioactivity levels and trace harmful metals leaching were measured. XRD, BEI and EDS were… More >

Abstract Periodontitis is a type of chronic inflammation in the gingival tissue caused by infectious bacteria colonizing the surface of the teeth, leading to the destruction of tooth-supporting tissues and loss of alveolar bone. Suberoylanilide hydroxamic acid (SAHA), a class of histone deacetylase (HDAC) inhibitor, has the potential to stimulate osteoblast differentiation by acetylating histone proteins, and thus suppressing the expression of adipogenic and chondrogenic genes. However, the effect of SAHA on the differentiation of human periodontal ligament stem cells (hPDLSCs) is yet to be elucidated. Herein, we investigated the effects of SAHA on in vitro More >

Abstract Paraoxonase-1 (PON1) is an important enzyme in various pathologies such as pesticide poisoning, diabetes, atherosclerosis, neuronal disorders, and cancer, due to its multifunctional activity since it acts on different metabolites. However, one of its main functions is the hydrolysis of organophosphate (OP) compounds from pesticides that cause fatal poisoning at the level of the central nervous system (CNS). The objective of this review was to investigate whether the structure, genetics, and function of PON1 affect the metabolism of organophosphate pesticides or other abnormalities. Information was selected from articles in the database PubMed–NCBI (https://www.ncbi.nlm.nih.gov/ pubmed/) with More >

Abstract Most studies focus on the adaptive immune cells in the GVHD pathogenesis, while little is known about innate immune cells in GVHD occurrence and development, especially macrophages. Meanwhile, a higher incidence of graft versus host disease (GVHD) is also found in the elderly patients. Though advances have been made in the modification of macrophages influenced by the inflamm-ageing, there is still no review on the role of macrophages in GVHD and the association between GVHD and the altered macrophages by inflamm-ageing. In this review, we focus on the potential age-related modifications of macrophage in GVHD, More >

Abstract Objective: The aim of this study is to detect in vitro the synergetic activity of colistin in combination with imipenem, amikacin or ciprofloxacin, at sub-inhibitory concentrations, against carbapenems-resistant (CR) Acinetobacter baumannii and Pseudomonas aeruginosa strains isolated from various wards in Annaba teaching hospital in eastern Algeria.
Materials and Methods: The minimal inhibitory concentrations (MIC) were determined by broth macrodilution (BMD). Carbapenemase encoding genes were screened using polymerase chain reaction (PCR). The activity of colistin in combination with second antibiotic was evaluated by the Checkerboard Technique.
Results: 39 CR P. aeruginosa and 21 CR A. baumanni strains where collected. The MIC values ranging… More >

Abstract Phosphorylation is a common type of post-translational modification (PTM). It plays a vital role in many cellular processes. The reversible phosphorylation and dephosphorylation affect protein structures and proteinprotein interactions. Previously, we obtained five proteins that interact with ethylene-responsive factor (ERF) from the cDNA library of Populus simonii x Populus nigra. To further investigate the effect of dephosphorylation of PsnERF on its protein binding ability, we generated different phosphorylation states of PsnERF and demonstrated their protein binding capacity by the yeast two-hybrid assay (Y2H). The secondary structures and 3D structures of PsnERF, ERFm, TrunERF, and psnerf^197/198/202a were predicted More >

Abstract As the world's population exponentially grows, so does the need for the production of food, with cereal production growing annually from an estimated 1.0 billion to 2.5 billion tons within the last few decades. This rapid growth in food production results in an ever increasing amount of agricultural wastes, of which already occupies nearly 50% of the total landfill area. For example, is the billions of dry tons of cellulose-containing spent coffee grounds disposed in landfills annually. This paper seeks to provide a method for isolating cellulose nanocrystals (CNCs) from spent coffee grounds, in order… More >

Abstract Introduction: To evaluate the reasons leading to an extended hospital stay (EHS) in patients undergoing radical cystectomy (RC) with postoperative enhanced recovery after surgery (ERAS) protocol.
Materials and methods: A total of 509 patients underwent RC and urinary diversion with ERAS between May 2012 and March 2017. The protocol includes no bowel preparation, early feeding, predominantly non-narcotic pain control, and μ opioid antagonists. Non-consenting/lost to follow-up patients, and those with non-urothelial carcinoma were excluded. We defined EHS as ≥ 5 postoperative days and compared the cohort to those with a length of stay (LOS) of ≤ 4… More >

Abstract In the present study, polybenzimidazole (PBI) polymer which has a great importance in polymer electrolyte membrane (PEM) research was synthesized via the solution polycondensation method, under various synthesis conditions to put forward the effect of the synthesis parameters on the properties of the synthesized polymer and consequently to the quality of the prepared polymer electrolyte membrane. The synthesized polymers were characterized in terms of their chemical structure, thermal degradation behaviour, and molecular weight by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (¹ H NMR), thermogravimetric analysis (TGA).
