Stomatal movements are enabled by changes in guard cell turgor facilitated via transient accumulation of inorganic and organic ions imported from the apoplast or biosynthesized within guard cells. Under salinity, excess salt ions accumulate within plant tissues resulting in osmotic and ionic stress. To elucidate whether (a) Na+ and Cl- concentrations increase in guard cells in response to long-term NaCl exposure and how (b) guard cell metabolism acclimates to the anticipated stress, we profiled the ions and primary metabolites of leaves, the apoplast and isolated guard cells at darkness and during light, that is, closed and fully opened stomata. In contrast to leaves, the primary metabolism of guard cell preparations remained predominantly unaffected by increased salt ion concentrations. Orchestrated reductions of stomatal aperture and guard cell osmolyte synthesis were found, but unlike in leaves, no increases of stress responsive metabolites or compatible solutes occurred. Diverging regulation of guard cell metabolism might be a prerequisite to facilitate the constant adjustment of turgor that affects aperture. Moreover, the photoperiod-dependent sucrose accumulation in the apoplast and guard cells changed to a permanently replete condition under NaCl, indicating that stress-related photosynthate accumulation in leaves contributes to the permanent closing response of stomata under stress.

Ethnopharmacological relevance: Sesame (Sesamum indicum, L., Family: Pedaliaceae) is a notable folk medicine in Middle East, Asia and Africa. Many traditional and pharmacological studies have documented the unique nature of sesame oil (SO). SO has been reported to have many pharmacological effects related to the anti-inflammatory and antioxidant capacity of its components. Neuroinflammation and oxidative stress have been the predominant pathogenic events in Alzheimer’s disease (AD) which is one of the most common neurodegenerative diseases. Aim of study: we aimed to explore the neuroprotective effect and the probable mechanisms of SO against aluminium chloride (AlCl3)-induced AD symptoms. Materials and methods: Rats were treated daily with AlCl3 (100 mg/kg/i.p.) either alone or with SO (two different doses) for six weeks. Behavioral (Open-field and Morris water maze tests), histopathological, and biochemical examinations were used to evaluate the neuroprotective effect and the underlying mechanisms of SO against AlCl3-induced AD symptoms. Results: Our results indicated that SO significantly improved learning and memory impairments induced by AlCl3. Indeed, SO treatment significantly restored the elevated level of acetylcholinesterase (AChE) and amyloid beta (A beta) overexpression. Moreover, AlCl3 treatment afforded histopathological changes, increase the expression of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) in addition to mitigation of oxidative stress status in the brain. SO abolished all these abnormalities. Meanwhile, AlCl3 induced activation of p38 mitogenactivated protein kinase (p38MAPK) and decreased brain-derived neurotrophic factor (BDNF) which were inhibited by SO. Furthermore, SO administration modulated the expression of the peroxisome proliferatoractivated receptor gamma (PPAR-gamma) and nuclear factor kappa B (NF-kappa B). Conclusions: In conclusion, the neuroprotective effect of SO involved the modulation of different mechanisms targeting oxidative stress, neuroinflammation, and cognitive functions. SO may modulate different molecular targets involved in AD pathogenesis by alterations of NF-kappa B/p38MAPK/BDNF/PPAR-gamma signalling and this may be attributed to the synergistic effect of their active components.

Highly stable antioxidant dispersions were designed on the basis of ring-opened ellagic acid (EA) intercalated into MgAl-layered double hydroxide (LDH) nanoparticles. The morphology of the composite was delicately modified with ethanolic washing to obtain EtOH-EA-LDH with a high specific surface area. The colloidal stability was optimized by surface functionalization with positively charged polyelectrolytes. Polyethyleneimine (PEI), protamine sulfate (PS) and poly(acrylamide-co-diallyl dimethyl ammonium chloride) (PAAm-co-DADMAC) was adsorbed onto the surface of the oppositely charged EtOH-EA-LDH leading to charge neutralization and overcharging at appropriate doses. Formation of adsorbed polyelectrolyte layers provided remarkable colloidal stability for the EtOH-EA-LDH. Modification with PEI and PAAm-co-DADMAC outstandingly improved the resistance of the particles against salt-induced aggregation with a critical coagulation concentration value above 1 M, while only limited stability was achieved by covering the nanoparticles with PS. The high antioxidant activity of EtOH-EA-LDH was greatly preserved upon polyelectrolyte coating, which was proved in the scavenging of radicals in the test reaction applied. Hence, an active antioxidant nanocomposite of high drug dose and remarkable colloidal stability was obtained to combat oxidative stress in systems of high electrolyte concentrations.

Antifogging films are essential in many areas, such as eyeglasses, windshields, goggles and so on. In this work, a transparent antifogging film was successfully prepared on glass by spin-coating a mixture of poly(acrylic acid) (PAA), carboxymethyl cellulose (CMC) and iron (III) chloride hexahydrate (FeCl3.6H(2)O). The coated film was superhydmphilic and showed excellent anti-frosting and self-healing properties. The composite coating was resistant to fouling by oil and had a very small water sliding angle about 3.1 degrees. This coating could maintain its antifogging performance after by tape-peeling test for 80 cycles and being exposed to UV irradiation for 96 h. The diverse desirable functions demonstrated and the facile preparation procedure of the film offer huge potential in many practical applications.

Background: Stem cell therapy is gaining momentum as an effective treatment strategy for degenerative diseases. Adult stem cells isolated from various sources (i.e., cord blood, bone marrow, adipose tissue) are being considered as a realistic option due to their well-documented therapeutic potentials. Our previous studies standardized a method to isolate circulating multipotent cells (CMCs) that are able to sustain long term in vitro culture and differentiate towards mesodermal lineages. Methods: In this work, long-term cultures of CMCs were stimulated to study in vitro neuronal and myogenic differentiation. After induction, cells were analysed at different time points. Morphological studies were performed by scanning electron microscopy and specific neuronal and myogenic marker expression were evaluated using RT-PCR, flow cytometry and western blot. For myogenic plasticity study, CMCs were transplanted into in vivo model of chemically-induced muscle damage. Results: After neurogenic induction, CMCs showed characteristic dendrite-like morphology and expressed specific neuronal markers both at mRNA and protein level. The calcium flux activity of CMCs under stimulation with potassium chloride and the secretion of noradrenalin confirmed their ability to acquire a functional phenotype. In parallel, the myogenic potential of CMCs was confirmed by their ability to form syncytium-like structures in vitro and express myogenic markers both at early and late phases of differentiation. Interestingly, in a rat model of bupivacaine-induced muscle damage, CMCs integrated within the host tissue taking part in tissue repair. Conclusion: Overall, collected data demonstrated long-term cultured CMCs retain proliferative and differentiative potentials suggesting to be a good candidate for cell therapy.

Accelerated nucleophilic substitution reactions of dansyl chloride with aniline under ambient conditions via dual-tip reactive paper spray

Paper spray ionization (PSI) mass spectrometry (MS) is an emerging tool for ambient reaction monitoring via microdroplet reaction acceleration. PSI-MS was used to accelerate and monitor the time course of the reaction of dansyl chloride with aniline, in acetonitrile, to produce dansyl aniline. Three distinct PSI arrangements were explored in this study representing alternative approaches for sample loading and interaction; conventional single tip as well as two novel setups, a dual-tip and a co-axial arrangement were designed so as to limit any on-paper interaction between reagents. The effect on product abundance was investigated using these different paper configurations as it relates to the time course and distance of microdroplet travel. It was observed that product yield increases at a given distance and then decreases thereafter for all PSI configurations. The fluorescent property of the product (dansyl aniline) was used to visually inspect the reaction progress on the paper substrate during the spraying process. Amongst the variety of sample loading methods the novel dual-tip arrangement showed an increased product yield and microdroplet density, whilst avoiding any on-paper interaction between the reagents.

Resistance of phosphogypsum-based supersulfated cement to carbonation and chloride ingress

The search for cements with lower CO2 emissions and lower consumption of non-renewable materials has been a challenge for the cement industry. The aim of this study was to investigate the resistance of SSC concrete to carbonation and chloride ingress. Portland cements (CEM I and CEM III/B) were used as a comparison. The results showed that the carbonation was very advanced in the SSC concretes. This is related to the exclusive formation of C-S-H and ettringite as hydration products, which present a higher rate of carbonation than portlandite. The SSC concrete has a good performance in terms of chloride penetration, mainly due to the increased ability to combine chloride ions both physically and chemically. The service life estimation showed that SSC concretes could be suitable for rural and urban environments when low w/c ratios (0.40) are used. All SSC mixtures studied were suitable for chloride environments. (C) 2020 Elsevier Ltd. All rights reserved.

Examination of inorganic gaseous species and condensed phases during coconut husk combustion based on thermodynamic equilibrium predictions

Multi-component thermodynamic equilibrium predictions of coconut husk combustion products were performed in this work. The calculation results showed that the concentration of the chlorine species in the flue gas and ash were clearly influenced by the combustion temperature. At temperatures below 820 degrees C the highest concentration was HCl(g), and above 820 degrees C was KCl(g). Chlorine species were also observed in ash, as KCl-NaCl-RbCl solid solution (when the combustion temperature was lower than 700 degrees C), and KCl-NaCl-K2SO4-Na2SO4 liquid solution (in the range of 600-960 degrees C). At low combustion temperatures (600 degrees C), chlorine retention in solid ash was the most effective. Speciation of inorganic gaseous species and condensed phases were investigated also during flue gas cooling from 1000 to 200 degrees C. Major condensed phase compositions were dominated by alkali metal salts in both solid and liquid phase states. In addition, the Gibbs energy of substance formation, and Gibbs reaction energy, in order to thoroughly interpret the thermodynamic predictions were determined. Finally, thirty seven eutectic points for binary systems calculated in the Phase Diagram module of the FactSage package were presented. For the purposes of interpreting the results, the melting point ranking for pure substances and binary systems were created. (c) 2020 Elsevier Ltd. All rights reserved.

Genetic deletion of connexin 37 causes polyuria and polydipsia

The connexin 37 (Cx37) channel is clustered at gap junctions between cells in the renal vasculature or the renal tubule where it is abundant in basolateral cell interdigitations and infoldings of epithelial cells in the proximal tubule, thick ascending limb, distal convoluted tubule and collecting duct; however, physiological data regarding its role are limited. In this study, we investigated the role of Cx37 in fluid homeostasis using mice with a global deletion of Cx37 (Cx37(-/-) mice). Under baseline conditions, Cx37(-/-) had similar to 40% higher fluid intake associated with similar to 40% lower urine osmolality compared to wild-type (WT) mice. No differences were observed between genotypes in urinary adenosine triphosphate or prostaglandin E2, paracrine factors that alter renal water handling. After 18-hours of water deprivation, plasma aldosterone and urine osmolality increased significantly in Cx37(-/-) and WT mice; however, the latter remained similar to 375 mmol/kg lower in Cx37(-/-) mice, an effect associated with a more pronounced body weight loss despite higher urinary AVP/creatinine ratios compared to WT mice. Consistent with this, fluid intake in the first 3 hours after water deprivation was 37% greater in Cx37(-/-) vs WT mice. Cx37(-/-) mice showed significantly lower renal AQP2 abundance and AQP2 phosphorylation at serine 256 than WT mice in response to vehicle or dDAVP, suggesting a partial contribution of the kidney to the lower urine osmolality. The abundance and responses of the vasopressin V-2 receptor, AQP3, NHE3, NKCC2, NCC, H+-ATPase, alpha ENaC, gamma ENaC or Na+/K+-ATPase were not significantly different between genotypes. In summary, these results demonstrate that Cx37 is important for body water handling.

Durability of recycled aggregate thermal insulation concrete under combined flexural loading and freeze-thaw cycles

A testing program including freeze-thaw cycles and flexural-loading combined action was designed to investigate the durability of recycled aggregate thermal insulation concrete (RATIC). The volume replacement ratios of recycled coarse aggregates (RCAs) were 0, 30, 50, 70, and 100%, and the flexural-load ratios were 0, 15, 30, 45%, and the glazed hollow bead particles (GHBs) with volume percentage of 130% were added. To evaluate the performance of RATIC, the relative dynamic modulus of elasticity (RDME) and mass loss rate (MLR) were estimated. The results show that the flexural-load stress exhibited an obvious negative effect on the freeze-thaw resistance of RATIC. With a 45% flexural-load ratio, RATIC fractured even before the load cycles reached 30. The decrease in the RDME was accelerated by the flexural-load stress, whereas this stress exhibited little effect on MLR. The durability performance of RATIC under combined actions decreases with the increase in the RCA replacement ratio, whereas the performance increased with the increment in the thermal insulation aggregate GHBs. Further to reveal the mechanism of RATIC under double actions, scanning electron microscopy, X-ray diffraction, and a new method of fluorescence analysis were employed. The results showed the existence of more micropores and microcracks in the tensile area. Further, compared to the new interfacial transition zones (ITZs), the microcracks in old ITZs caused by combined actions aggravated the damage caused in the freeze-thaw cycles.
