Hongwei Song, Fang Xie, Weiwei Chen, Jinrong Liu
This study investigated a forward osmosis and membrane distillation (FO/MD) hybrid system for real dairy wastewater (DWW) recycling. Two types of FO membranes, cellulose triacetate-embedded polyester screen support (CTA-ES) and aquaporin inside (AQP), were employed. Sodium chloride was used as the draw solution. A cross-flow FO cell and an air gap membrane distillation module were established to conduct individual FO experiments and FO/MD experiments. From the experiments, an analysis of the water flux (Jw), reverse draw solute flux (Js), Js/Jw ratio and contaminant rejection was performed...

AIM: The mammalian lung expresses at least three aquaporin (AQP) water channels whose precise role in lung injury or inflammation is still controversial. MATERIALS AND METHODS: Three murine models of lung inflammation and corresponding controls were used to evaluate the expression of Aqp1, Aqp4, Aqp5 and Aqp9: lipopolysaccharide (LPS)-induced lung injury; HCl-induced lung injury; and ventilation-induced lung injury (VILI). RESULTS: All models yielded increased lung vascular permeability, and inflammatory cell infiltration in the broncho-alveolar lavage fluid; VILI additionally produced altered lung mechanics...

Aquaporins (AQPs) can be revisited from a distinct and complementary perspective: the outcome from analyzing them from both plant and animal studies. (1) The approach in the study. Diversity found in both kingdoms contrasts with the limited number of crystal structures determined within each group. While the structure of almost half of mammal AQPs was resolved, only a few were resolved in plants. Strikingly, the animal structures resolved are mainly derived from the AQP2-lineage, due to their important roles in water homeostasis regulation in humans...

The mechanisms of Leishmania resistance to antimonials have been primarily determined in experimentally derived Leishmania strains. However, their participation in the susceptibility phenotype in field isolates has not been conclusively established. Being an intracellular parasite, the activity of antileishmanials is dependent on internalization of drugs into host cells and effective delivery to the intracellular compartments inhabited by the parasite. In this study we quantified and comparatively analyzed the gene expression of nine molecules involved in mechanisms of xenobiotic detoxification and Leishmania resistance to antimonial drugs in resistant and susceptible laboratory derived and clinical L...

The dehydration-responsive element binding protein (DREB) family of transcription factors is associated with abiotic stress responses during plant growth and development. This study focussed on the subfamily member DREB1B, which was initially described as highly and specifically responsive to low temperature. However, here it is shown that DREB1B is not only involved in cold tolerance but also other abiotic stress tolerances, such as that of drought. To further understand the genetic improvement effects of the drought tolerance provided by RdreB1BI in transgenic strawberry, drought stress responses of transgenic plants were evaluated at the morphological, physiological, and transcriptional levels...

The unique properties of brain capillary endothelium, critical in maintaining the blood-brain barrier (BBB) and restricting water permeability across the BBB, have important consequences on fluid hydrodynamics inside the BBB hereto inadequately recognized. Recent studies indicate that the mechanisms underlying brain water dynamics are distinct from systemic tissue water dynamics. Hydrostatic pressure created by the systolic force of the heart, essential for interstitial circulation and lymphatic flow in systemic circulation, is effectively impeded from propagating into the interstitial fluid inside the BBB by the tightly sealed endothelium of brain capillaries...

Aquaporins (AQPs) are transmembrane protein channels that are members of Major Intrinsic Proteins (MIP) superfamily. AQPs play important roles in plant reproduction, cell elongation, osmoregulation, influence leaf physiology and are responsive to drought and salt tolerance. Small intrinsic proteins (SIPs)belongs to one of the groups of AQPs, which are mainly localized to endoplasmic reticulum(ER). While this group of aquaporin is being well studied in Arabidopsis, grape and other plant species, not much is known about the molecular regulatory mechanisms driven by ER-type AQPs in Glycine Max...

Aquaporins (AQP) are proteins that form channels to facilitate the movement of water across cell membranes in plants, bacteria and animals. Insect AQPs are indispensable for cellular water management under stress, including dehydration and cold. To better understand the biological significance of molecular evolution of gene sequences, followed by structural and functional specialization, the present study used ClustalX2.1, MEGA7.0, Jalview and Mesquite software to build an insect AQP phylogenetic tree and visualize the evolutionary associations among insect AQPs...

The loss of salivary gland function caused by radiation therapy of the head and neck is a serious condition and it affects a patient's quality of life. The current lack of effective therapies demands new options to be explored. This study tested whether human salivary gland epithelial cells (SGECs) could be successfully cultured on a decellularized porcine gut matrix (SIS-muc) in both mono- and coculture with microvascular endothelial cells (mvECs). By performing immunofluorescence imaging, transmission as well as scanning electron microscopy (SEM), quantitative polymerase chain reaction (qPCR), and an amylase enzyme assay, it was investigated as to what extent the three-dimensional (3D)-cultured cells could maintain their molecular differentiation and the production of working α-amylase (α-AMY) compared with two-dimensional (2D) culture...

Structural studies have paved the avenue to a deeper understanding of aquaporins (AQPs), small ancient proteins providing efficient transmembrane pathways for water, small uncharged solutes such as glycerol, and possibly gas molecules. Despite the numerous studies, their roles in health and disease remain to be fully disclosed. The recent discovery of Au(III) complexes as potent and selective inhibitors of aquaglyceroporin isoforms paves the way to their possible therapeutic application. The binding of the selective human AQP3 inhibitor, the cationic complex [Au(bipy)Cl2 ](+) (Aubipy), to the protein channel has been investigated here by means of a multi-level theoretical workflow that includes QM, MD and QM/MM approaches...

The receptor for advanced glycation end-products (RAGE) is involved in inflammatory response during acute respiratory distress syndrome (ARDS). Growing body of evidence support strategies of RAGE inhibition in experimental lung injury, but its modalities and effects remain underinvestigated. Anesthetised C57BL/6JRj mice were divided in four groups; three of them underwent orotracheal instillation of acid and were treated with anti-RAGE monoclonal antibody (mAb) or recombinant soluble RAGE (sRAGE), acting as a decoy receptor...

Some members of aquaporin family (AQP) plays crucial functions in salivary synthesis and secretion. These proteins expression has already been reported during salivary gland formation, however no previous studies in human developing glands have been performed. We evaluated AQP1, 3 and 5 expression through the stages of human salivary gland morphogenesis and discuss the possible role of AQP for glandular maturation. Human salivary glands derived from foetuses aged between 14 and 25 weeks were submitted to immunohistochemistry...

The nucleus pulposus (NP) is an avascular, hydrated tissue that permits the intervertebral disc to resist compressive loads to the spine. To determine the mechanisms by which intervertebral disc degeneration is caused by the nucleus pulposus, the expression and regulation of nuclear factor (NF)‑κB and acid sensing ion channel 3 (ASIC3) were examined. For the intervertebral disc degeneration model, NP was harvested from the tail of rats and applied to the L5 dorsal root ganglion (DRG). The mechanical pain withdrawal threshold (PWT) in NP model rats was assessed...

To evaluate the relationship between serum hormone or aquaporin-2 (AQP-2) and preeclampsia, patients with severe preeclampsia (A group), mild preeclampsia (B group), chronic hypertension (C group) and normal pregnant women (D group) were recruited and analysed. The AQP-2 level in placenta tissues was detected and the correlations of AQP-2 with serum hormone levels were analysed using linear correlation regression analysis. The differences of alpha foetal protein (AFP) and human chorionic gonadotropin (HCG) levels during mid-pregnancy, as well as the levels of AFP, HCG, unconjugated oestriol and progesterone during late pregnancy were significant among A, B, C and D groups (p < ...

The formation of the proper number of nephrons requires a tightly regulated balance between renal progenitor cell self-renewal and differentiation. The molecular pathways that regulate the transition from renal progenitor to renal vesicle are not well understood. Here we show that Sall1interacts with the Nucleosome Remodeling and Deacetylase Complex (NuRD) to inhibit premature differentiation of nephron progenitor cells. Disruption of Sall1-NuRD in vivo in knock-in mice (ΔSRM) resulted in accelerated differentiation of nephron progenitors and bilateral renal hypoplasia...

Skin dryness and thickening are hallmarks of systemic sclerosis (SSc) disease. Aquaporins (AQPs) are plasma membrane proteins that transport glycerol and water, resulting in water retention and skin hydration. Expression of AQPs has been evaluated in human normal skin. However, expression of these proteins in SSc dermal fibroblasts has not yet been reported. The aim of this study was to assess the expression profile of AQPs in dermal fibroblasts of SSc patients. Fibroblast cells were extracted from SSc and healthy skin biopsies and characterized using fibroblast surface protein antibody...
