Singh, Suman,Gaikwad, Kirtiraj K.,Lee, Myungho,Lee, Youn Suk Elsevier 2018 Journal of food engineering Vol.234 No.-

<P><B>Abstract</B></P> <P>We successfully developed temperature-sensitive packaging using a eutectic mixture of soybean oil and tetradecane (S + T) as a thermo-regulating material (TRM). The eutectic mixture was vacuum impregnated inside expanded graphite (EG/S + T) to increase the thermal conductivity of the TRM. A thermal insulation coating (EG/RH/S + T) was prepared and applied inside the walls of the expanded polypropylene (EPP) boxes using EG/S + T and a rice byproduct, i.e., rice husk (RH), to enhance the thermal buffering. The developed eutectic mixture (S + T), EG/S + T, and thermal insulation coating (EG/RH/S + T) were characterized using scanning electron microscopy (SEM), thermogravimetric analysis, Fourier transform infrared (FTIR) spectroscopy, and differential scanning calorimetry (DSC). The SEM analysis indicated that the S + T TRM was sufficiently absorbed into the EG porous network. The FTIR results revealed that the S + T TRM and EG did not undergo chemical reactions however, physical interactions were observed. The DSC results revealed that the S + T TRM melts at −0.31 °C with a latent heat of 71.06 J/g, and it solidifies at −2.01 °C with a latent heat of 74.89 J/g. The thermal insulation coating melts at −0.94 °C with a latent heat of 19.49 J/g, and it solidifies at −3.93 °C with a latent heat of 19.35 J/g. Temperature sensitive package further studied with fresh beef to determine weather is could provide temperature maintain or not up to-8 days. Meat sample place inside the small PET container and cover with cling film. PET tray transfer to temperature sensitive package. The quality of the fresh beef was determined based on its pH, color, texture, total volatile basic nitrogen, and total plate count. EPP boxes with EG/RH/S + T coatings and a G-Pack show excellent temperature control during 3 h of storage at ambient temperature. All the quality parameters for fresh beef are within the acceptable range when using the temperature-sensitive packaging. The developed temperature-sensitive packaging is useful to control the temperature of fresh beef from the store to preparation and consumption.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Temperature-sensitive packaging was successfully developed using soybean oil and tetradecane as a thermo-regulating material. </LI> <LI> EPP boxes with EG/RH/S + T coatings and a G-Pack show excellent temperature control during 3 h of storage at ambient temperature. </LI> <LI> All the quality parameters for fresh beef are within the acceptable range when using the temperature-sensitive packaging. </LI> </UL> </P>

Singh, Suman,Gaikwad, Kirtiraj K.,Lee, Youn Suk Korea Society of Packaging Science and Technology 2018 한국포장학회지 Vol.24 No.3

Interest in the use of smart packaging systems for food products has increased in recent years. Therefore, food researchers are focusing on the development of new indicator based smart packaging technologies by using anthocyanin-based natural dye. Anthocyanins are one of the plant constituents known as flavonoids and responsible for the bright and attractive orange, red, purple, and blue colors of most fruits, vegetables, flowers, and some cereal grains. Indicators of natural dyes such as anthocyanins could express the quality and shelf life of perishable food products. However, the sensitivity and stability for their use in smart food packaging should be established to reach the market proposals. This review article focuses on recent studies related to use of natural dyes based on anthocyanin for smart food packaging applications. This study offers valuable insight that may be useful for identifying trends in the commercialization of natural dyes or for identifying new research areas. This review also provides food and packaging scientists with a thorough understanding of the benefits of anthocyanin-based natural dyes for shelf life indicator when applied to package material specific foods and hence can assist in accelerating commercial adoption.

Bisla, Suman,Gupta, Ambika,Agarwal, Shalini,Singh, Harneet,Sehrawat, Ankita,Singh, Aarti The Korean Dental Society of Anesthsiology 2021 Journal of Dental Anesthesia and Pain Medicine Vol.21 No.6

Background: Trigeminal neuralgia (TN) is a severe form of pain that affects the daily activities of a patient. Transcutaneous electrical nerve stimulation (TENS) therapy is an emerging option for the treatment of acute and chronic pain. The aim of this study was to evaluate the effect of TENS therapy as an adjunct to drug therapy for the treatment of TN. Methods: A total of 52 patients diagnosed with TN according to the International Classification of Headache Disorders (version 3) were included. Each patient was randomized to either the TENS or placebo TENS groups. Intervention was given in continuous mode and 100-Hz frequency for 20 mins biweekly for 6 weeks. Parameters were measured at baseline, TENS completion and 3 months, 6 months, and 1 year of follow up. The parameters observed were mean carbamazepine dose, mean visual analog scale (VAS) score, mean present pain intensity (PPI) score, and functional outcome. Non-parametric analyses, one-way ANOVA and the Kruskal-Wallis test were applied for intragroup comparisons, while the Mann-Whitney U test and independent t-test were used for intergroup comparisons of variables. The chi-square test was applied to analyze categorical data. Results: Compared to the placebo TENS group, the mean dose of carbamazepine in the TENS group was significantly reduced at TENS completion, as well as at 6 months and 1 year follow up. Changes in mean VAS score, mean PPI score, and functional outcome did not show significant differences between the groups (P>0.05). Conclusion: TENS therapy does not lead to any changes in pain levels but it may reduce the mean dose of carbamazepine when used as an adjunct treatment in patients with TN.

Suman Rani,Balwinder Singh,Rekha Devi 한국전기전자재료학회 2021 Transactions on Electrical and Electronic Material Vol.22 No.6

1-Trit and 2-Trit Ternary comparator circuits using Complementary Metal–Oxide–Semiconductor (CMOS) as well as Carbon Nanotube Field-Effect Transistor (CNTFET) is proposed and investigated for Low Power High-performance applications. The design and simulation are investigated and authenticated using Hailey Simulation Program with Integrated Circuit (HSPICE) with Predictive technology model (PTM) low power 32 nm metal gate/High-K/Strained-Si Model for CMOS and 32 nm Stanford Model for CNTFET. The CNTFET based design is compared with the CMOS design in terms of signifi cant design aspects, specifically delay, Average Power consumption and Power delay product (PDP). A comparison is performed among CMOS and CNTFET based ternary comparator circuits which reveals that CNTFETs can lead to more efficient ternary circuits. In terms of delay and power consumption, the CNTFET based 1-Trit Ternary Comparator performs better than the CMOS based 1-Trit Ternary Comparator as the delay and Average power consumption are reduced by 89.7% and 57.3% in CNTFET type as compared to the CMOS based 1-Trit Ternary Comparator design. Similarly, in the case of the 2-Trit comparator, the CNTFET based design performs better than the CMOS-based design as the delay and Average power consumption are reduced by 88.7% and 42% in the CNTFET type.

Background Despite plant's ability to adapt and withstand challenging environments, drought poses a severe threat to their growth and development. Although pigeon pea is already quite resistant to drought, the prolonged dehydration induced by the aberrant climate poses a serious threat to their survival and productivity. Objective Comparative physiological and transcriptome analyses of drought-tolerant (CO5) and drought-sensitive (CO1) pigeon pea genotypes subjected to drought stress were carried out in order to understand the molecular basis of drought tolerance in pigeon pea. Methods The transcriptomic analysis allowed us to examine how drought affects the gene expression of C. cajan. Using bioinformatics tools, the unigenes were de novo assembled, annotated, and functionally evaluated. Additionally, a homology-based sequence search against the droughtDB database was performed to identify the orthologs of the DEGs. Results 1102 potential drought-responsive genes were found to be differentially expressed genes (DEGs) between drought-tolerant and drought-sensitive genotypes. These included Abscisic acid insensitive 5 (ABI5), Nuclear transcription factor Y subunit A-7 (NF-YA7), WD40 repeat-containing protein 55 (WDR55), Anthocyanidin reductase (ANR) and Zinc-finger homeodomain protein 6 (ZF-HD6) and were highly expressed in the tolerant genotype. Further, GO analysis revealed that the most enriched classes belonged to biosynthetic and metabolic processes in the biological process category, binding and catalytic activity in the molecular function category and nucleus and protein-containing complex in the cellular component category. Results of KEGG pathway analysis revealed that the DEGs were significantly abundant in signalling pathways such as plant hormone signal transduction and MAPK signalling pathways. Consequently, in our investigation, we have identified and validated by qPCR a group of genes involved in signal reception and propagation, stress-specific TFs, and basal regulatory genes associated with drought response. Conclusion In conclusion, our comprehensive transcriptome dataset enabled the discovery of candidate genes connected to pathways involved in pigeon pea drought response. Our research uncovered a number of unidentified genes and transcription factors that could be used to understand and improve susceptibility to drought.

The surge in the oil prices, increasing global population, climate change, and waste management problems are the major issues which have led to the development of biofuels from lignocellulosic wastes. Cellulosic or second generation (2G) bioethanol is produced from lignocellulosic biomass via pretreatment, hydrolysis, and fermentation. Pretreatment of lignocellulose is of considerable interest due to its influence on the technical, economic and environmental sustainability of cellulosic ethanol production. In this study, furniture waste sawdust was subjected to alkaline peroxide (H₂O₂) for the production of reducing sugars. Sawdust was pretreated at different concentrations from 1-3% H₂O₂ (v/v) loadings at a pH of 11.5 for a residence time of 15-240 min at 50, 75 and 90 ℃. Optimum pretreatment conditions, such as time of reaction, operating temperature, and concentration of H₂O₂, were varied and evaluated on the basis of the amount of total reducing sugars produced. It was found that the changes in the amount of lignin directly affected the yield of reducing sugars. A maximum of 50% reduction in the lignin composition was obtained, which yielded a maximum of 75.3% total reducing sugars yield and 3.76 g/L of glucose. At optimum pretreatment conditions of 2% H₂O₂ loading at 75 ℃ for 150 min, 3.46 g/L glucose concentration with a 69.26% total reducing sugars yield was obtained after 48 hr. of the hydrolysis process. Pretreatment resulted in lowering of crystallinity and distortion of the sawdust after the pretreatment, which was further confirmed by XRD and SEM results.
