Energy storage system design for large-scale solar PV in Malaysia: technical and environmental assessments

The Paris agreement, signed in 2015, is a commitment by the nations to set targets to reduce greenhouse gases emissions. In line with that, Malaysia is committed to lower its greenhouse gases emissions by 45% by 2030. This target is supported by the massive projects of Large-Scale Solar PV, of which 1 GW will be operating by 2020. However, the peak generation of this huge capacity, which occurs at noon, will not meet the peak electricity demand which occurs in the morning and in the evening, and this issue, in such scale, has not been addressed yet. Besides the direct use of solar generated electricity, storing electricity at the peak generation time and delivering it at the desired time may be the best usage of such intermittent energy. This project aims to design the optimal large-scale storage system for the Malaysian scenario. A comprehensive power system is simulated through HOMER Pro, including various storage technologies in different locations, selected according to the planned Large-Scale Solar capacity, the solar irradiation and the electricity demand. The power system has been sized according to two approaches. In the first approach, the storage is sized to satisfy the night peak demand, which occurs between 8pm and 10pm. In the second approach, the daily average demand is determined, and the storage is sized to satisfy all the demand above this average. The proposed power system is feasible only in five locations under the first approach, and not feasible in all the locations under the second approach. Based on HOMER Pro simulation outcomes, the best energy storage type is the 1 MWh Zinc Bromide flow battery.

lncRNA CASC2 inhibits lipopolysaccharide-induced acute lung injury via miR-27b/TAB2 axis

Long non-coding RNA (lncRNA) cancer susceptibility candidate 2 (CASC2) has been reported to exert an important role in acute lung injury (ALI). The present study aimed to investigate the potential underlying mechanism of CASC2 in ALI progression. Reverse transcription-quantitative PCR was conducted to examine the expression of CASC2, microRNA (miR/miRNA)-27b and TGF-beta activated kinase 1 and MAP3K7-binding protein 2 (TAB2) in A549 cells. Cell viability and apoptosis were analyzed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry. Enzyme-linked immunosorbent assay was used to measure the levels of inflammatory-related cytokines to assess the inflammatory response, including interleukin-1 beta (IL-1 beta), IL-6 and tumor necrosis factor alpha (TNF-alpha). The binding sites of miR-27b in CASC2 or TAB2 were predicted using LncBase or microT-CDS software, following which dual-luciferase reporter and RNA binding protein immunoprecipitation assays were performed to confirm the target relationship between miR-27b and CASC2 or TAB2. The protein expression of TAB2 was detected by western blotting. The decreased viability, and increased apoptosis and inflammatory responses were attenuated by the accumulation of CASC2 in lipopolysaccharide (LPS)-stimulated A549 cells. CASC2 could directly bind to miR-27b in A549 cells. CASC2 protected A549 cells from LPS-triggered injury by downregulating miR-27b. TAB2 was a target of miR-27b in A549 cells. The influence of miR-27b depletion was reversed by the silencing of TAB2 in an ALI cell model. CASC2 could increase the expression of TAB2 by serving as a competing endogenous RNA of miR-27b in A549 cells. Collectively, the results suggested that CASC2 attenuated LPS-induced injury in the ALI cell model by modulating the miR-27b/TAB2 axis.

Enhanced adsorption of chromium(VI) from aqueous medium by basic nanohydroxyapatite/chitosan composite based on egg shell

Four solid adsorbents namely nanohydroxyapatite (NP), cetyltrimethyl ammonium bromide modified nanohydroxyapatite (NPB), and nanohydroxyapatite/chitosan composite either in acidic (NPS1) or basic media (NPS2) were prepared based on egg shell as a biosource. Solid materials were characterized by N-2 adsorption/desorption isotherms, scanning electron microscopy, X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, and point of zero charges. The thermal, textural, and chemical properties of nanohydroxyapatite/chitosan composite prepared in basic medium were found to be more enhanced than the other three solid adsorbents with surface area and pore radius of 152.5 m(2)/g and 5.11 nm, respectively. pH(PZC) for all the prepared solid samples ranged between 6.8 and 7.5. Adsorption of hexavalent chromium were studied under different application condition such as the effect of adsorbent dosage, time, pH, initial Cr(VI) concentration, and temperature. The maximum adsorption capacities of chromium onto NP, NPS1, NPS2, and NPB (119.047, 131.578, 134.048, and 85.397 mg/g, respectively) were observed at pH 6. Thermodynamic and kinetic parameters proved that adsorption of Cr(VI) onto all the investigated solid adsorbents follow pseudo-second-order kinetic model, spontaneous, and endothermic adsorption process.

Benzyl Isothiocyanate Induces Apoptosis via Reactive Oxygen Species-Initiated Mitochondrial Dysfunction and DR4 and DR5 Death Receptor Activation in Gastric Adenocarcinoma Cells

Benzyl isothiocyanate (BITC) is known to inhibit the metastasis of gastric cancer cells but further studies are needed to confirm its chemotherapeutic potential against gastric cancer. In this study, we observed cell shrinkage and morphological changes in one of the gastric adenocarcinoma cell lines, the AGS cells, after BITC treatment. We performed 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, a cell viability assay, and found that BITC decreased AGS cell viability. Reactive oxygen species (ROS) analyses using 2 ‘,7 ‘-dichlorofluorescin diacetate (DCFDA) revealed that BITC-induced cell death involved intracellular ROS production, which resulted in mitochondrial dysfunction. Additionally, cell viability was partially restored when BITC-treated AGS cells were preincubated with glutathione (GSH). Western blotting indicated that BITC regulated the expressions of the mitochondria-mediated apoptosis signaling molecules, B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), and cytochrome c (Cyt c). In addition, BITC increased death receptor DR5 expression, and activated the cysteine-aspartic proteases (caspases) cascade. Overall, our results showed that BITC triggers apoptosis in AGS cells via the apoptotic pathways involved in ROS-promoted mitochondrial dysfunction and death receptor activation.

MgFeAl layered double hydroxide prepared from recycled industrial solid wastes for CO2 fixation by cycloaddition to epoxides

MgFeAl trimetallic layered double hydroxide (LDH) was prepared using industrial solid wastes of red mud and ferronickel slag, and exfoliation of the LDH by acetone washing resulted in a final product with high surface area (319 m(2)/g). It showed a CO2 adsorption capacity of 70.2 mg/g at 298 K and 1 bar, which was somewhat higher than that of a similar LDH synthesized using pure chemicals (63.8 mg/g). The LDH was tested as a catalyst for solvent-free CO2 cycloaddition to various epoxides. Significant conversion of epoxides and high selectivity to the corresponding cyclic carbonates were obtained under mild reaction conditions. The LDH achieved an excellent result of 98.0% conversion of epichlorohydrin and 98.2% selectivity to the cyclic carbonate in the presence of tetrabutylammonium bromide as co-catalyst at 50 degrees C and 5 bar after 7 h, catalyzed by the combination of Lewis acidic metal sites and bromide ions. The LDH was recovered after the reaction and maintained good catalytic performances after five repeated runs without any significant loss in catalytic activity. This work demonstrated that effective CO2 capture/utilization could be achieved simultaneously using a porous material easily prepared from industrial wastes.

Melanogenesis Effect of 7-acetoxy-4-methylcoumarin in B16F10 Melanoma Cells

The increased interest in anti-whitening dyes has enhanced the research interest to identify efficient melanogenic activators. Melanogenesis is the process of melanin production by melanocytes in the hair follicles and skin, which is mediated by several enzymes, such as microphthalmia-associated transcription factor (MITF), tyrosinase (TYR), tyrosinase-related protein (TRP)-1, and TRP-2. This study investigated the melanogenesis-stimulating effect of 4-Methylumbelliferone (4MUMB) and its synthetic derivatives, 7-acetoxy-4-methylcoumarin (7A4MC) and 4-methylheriniarin (4MH) in B16F10 melanoma cells. The cytotoxicity of these compounds was investigated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, followed by the assessment of the melanin content and the intracellular TYR activity. Finally, the expression levels of the key enzymes involved in melanogenesis were investigated. 7A4MC increased melanin production in B16F10 cells relative to that by 4MUMB and 4MH treated cells in a dose-dependent manner without significant cytotoxicity. Concomitantly, 7A4MC significantly increased TYR activity and enhanced the expression of MITF, which significantly induced the expression of TRP-1, TRP-2, and TYR. Furthermore, 7A4MC stimulated melanogenesis via increased phosphorylation of c-Jun N-terminal kinases (JNK) and reduced phosphorylation of protein kinase B (AKT). These results confirmed the melanogenesis-inducing effects of 7A4MC and indicated its potential use as an anti-hair bleaching agent in cosmetics industries.

Impact of nanostructured lipid carriers on dapsone delivery to the skin: in vitro and in vivo studies

The main objective of this study was to develop, characterize and evaluate the potential use of dapsone-loaded nanostructured lipid carriers (NLCs) as a topical treatment for acne. Differently charged NLC formulations were successfully prepared using an emulsification/sonication method. The particle sizes ranged from 106.2 +/- 5.6 nm to 151.3 +/- 7.4 nm, and the NLCs possessed the predicted surface charges, depending on the emulsifier used (Tween 80, Transcutol P, or cetyltrimethylammonium bromide). The entrapment efficiencies ranged from 76.5 +/- 3.8% to 91.1 +/- 3.9%. Selected formulations were assessed for possible interactions, in vitro release, ex vivo skin permeation, pharmacological efficacy and safety compared with a hydroalcoholic solution. Dapsone was embedded in the lipid matrix of NLCs and behaved as controlled release system with a good occlusive effect. Dapsone-loaded cationic NLC formulation enhanced the skin permeation of dapsone, increase the amount of dapsone retained in the skin in controlled manner, and improved the anti-rosacea activity. Based on these encouraging results, cationic NLC represents a promising carrier for the safe topical delivery of dapsone.

Effect of topical ophthalmic instillation of rocuronium bromide on the intraocular pressure of kestrels (Falco tinnunculus) and little owls (Athene noctuae)

OBJECTIVE To assess the effect of rocuronium bromide-induced mydriasis on the intraocular pressure (IOP) of kestrels (Falco tinnunculus) and little owls (Athene noctuae). ANIMALS 13 adult kestrels and 13 adult little owls. PROCEDURES All birds were ophthalmologically normal. During the first of 2 treatment periods, a 1% rocuronium bromide solution was topically instilled in both eyes of all birds at a dose of 0.12 mg (12 mu L) for kestrels and 0.20 mg (20 mu L) for little owls. No ophthalmic treatments were administered during the second (control) treatment period, which was conducted 1 week after the first. During both treatment periods, rebound tonometry was used to measure IOP before rocuronium bromide instillation or at the beginning of the control period (baseline) and at predetermined times after baseline or until the pupillary light reflex returned to normal. All IOP measurements were obtained between 8 am and 5 pm. RESULTS The mean IOP did not differ significantly from baseline for either species during the control treatment period. During the rocuronium bromide treatment period, complete mydriasis was achieved in all birds. The mean IOP was significantly decreased from baseline and from the corresponding mean IOP for the control period beginning 60 and 30 minutes after drug instillation for kestrels and owls, respectively, and reached its nadir at 60 minutes after drug instillation for both species. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that topical instillation of rocuronium bromide in the eyes successfully induced mydriasis and decreased the IOP of common kestrels and little owls.
