Aims: This study aimed to find the association of liver biomarker with diabetes population. Also, this study focused to find out the risk factors associated with liver disease in Nepalese diabetes patient. Methods: This study was carried out among 238 diabetes and 238 apparently healthy population who attended Modern diagnostic laboratory and Research center, Kathmandu, Nepal. HbA1c and fasting plasma glucose was measure to assess the diabetes population and glycemic control. Aspartate to platelet ratio index (APRI), gamma-glutamyl transpeptidase to platelet ratio (GPR), fibrosis-4 index (FIB-4), and triglyceride and glucose index (TyG) were assess for prediction of hidden risk liver disease. Diabetic patient with higher than the cut-off value obtained from ROC curve analysis of different liver marker index were subjected to multivariate regression analysis to measure the independent risk factor for progression liver disease in different model. Results: Patient with poor glycemic control had a significantly higher level of APRI (P=0.05), GPR (P=0.039), and TyG (P<0.001). Higher HbA1c showed significantly positive correlation with APRI (r=0.154, P=0.017), GPR (r=0.203, P=0.002), FIB4 (r=0.132, P=0.042), and TyG (r=0.510, P<0.001) in diabetic population. The Area under ROC curve of GPR was 0.700 (0.654-0.747), APRI 0.839 (0.803-0.874), FIB-4 0.820 (0.783-0.857), and TyG 0.909 (0.882-0.874) with p-value <0.05. The cut-off value (sensitivity, specificity) of GPR was 0.227 (63.4%, 63%), APRI 0.241 (71.0%, 80.3%), FIB-4 1.65 (71.8%, 77.3%), and TyG 8.85 (79%, 93.3%) respectively. Triglyceride, AST, and GGT was independent risk factor followed same trend in different 4 model while HbA1c and ALT showed independent risk factor in 3 models. Conclusions: APRI, GPR, FIB4 and TyG can define the hidden risk liver disease in T2DM. The independent risk factors for progression of liver disease in those population are hypertriglyceridemia, higher AST, and higher GGT. Routinely screening for markers may prevent progression of liver disease in T2DM patients.
Solvent Assisted Dyeing of Silk Fabric Using Deep Eutectic Solvent as a Swelling Agent
Sushant S. Pawar,Ashok Athalye,Ravindra V. Adivarekar 한국섬유공학회 2021 Fibers and polymers Vol.22 No.2
Solvent assisted dyeing of silk fabric was studied with the aim to increase color strength of silk fabric with the helpof green, eco-friendly deep eutectic solvent (DES), which act as a swelling agent. The use of a DES in solvent assisted silkdyeing showed favorable results. Silk yarns showed better swelling properties in the DES than water. Process parameterssuch as temperature, time, and concentration of DES were optimized with the help of a design expert software. Lack of fit Fvalueand P-value of the ANOVA shows that the model is significant. Optimized solvent assisted silk dyeing was carried outwith acid dye and found to be better than that of conventional dyeing in aqueous medium. DES assisted dyed silk fabricshowed desired color strength at 60 oC for 37 min, which is 10 oC and 5-10 min lesser than the conventional dyeing of silkfabric. The percentage exhaustion of DES assisted dye bath was calculated and found to be good. DES assisted dyed silkfabric showed wash, light, and rubbing fastness properties comparable to conventional aqueous dyed silk fabric.
Blind symbol timing offset estimation for offset-QPSK modulated signals
Kumar, Sushant,Majhi, Sudhan Electronics and Telecommunications Research Instit 2020 ETRI Journal Vol.42 No.3
In this paper, a blind symbol timing offset (STO) estimation method is proposed for offset quadrature phase-shift keying (OQPSK) modulated signals, which also works for other linearly modulated signals (LMS) such as binary-PSK, QPSK, 𝜋/4-QPSK, and minimum-shift keying. There are various methods available for blind STO estimation of LMS; however, none work in the case of OQPSK modulated signals. The popular cyclic correlation method fails to estimate STO for OQPSK signals, as the offset present between the in-phase (I) and quadrature (Q) components causes the cyclic peak to disappear at the symbol rate frequency. In the proposed method, a set of close and approximate offsets is used to compensate the offset between the I and Q components of the received OQPSK signal. The STO in the time domain is represented as a phase in the cyclic frequency domain. The STO is therefore calculated by obtaining the phase of the cyclic peak at the symbol rate frequency. The method is validated through extensive theoretical study, simulation, and testbed implementation. The proposed estimation method exhibits robust performance in the presence of unknown carrier phase offset and frequency offset.

Bemisia tabaci is a serious pest in various horticultural crops in the world. The management of B. tabaci has been typically carried out by chemical pesticides. Due to the development of pesticide resistance and environmental contamination, however, it is necessary to develop alternative biopesticides using natural products from plants and natural enemies. Nicotiana benthamiana is a variety of wild tobacco plants and produce acyl sugars from glandular trichomes in the leaves. Acyl sugars are known to be highly toxic to various plant sapping insects such as whiteflies, aphids and thrips. Here, we extracted acyl sugars in two different ways from the leaves. At first, collected leaves were simply washed with water. Otherwise, collected leaves firstly dried and homogenized into the powder, then extracted with ethanol. Spray of 10% water-extracted solution into adult whiteflies showed 80% mortality. Otherwise, spray of 10% ethanol-extracted solutions showed complete mortality at 48 h after treatment and also strong repellency of adult whiteflies into the treated tomato plants. Our results suggest N. benthamiana is a useful for the control of whiteflies and can be used as an alternative natural pesticide for the whitefly management.

Bemisia tabaci is a serious pest in various horticultural crops in the world. Due to use of chemical pesticide for their management they develop pesticide resistance and environmental contamination. It is necessary to develop alternative bio-pesticides using natural products from plants and natural enemies. Nicotiana benthamiana is a variety of wild tobacco plants and produce acyl sugars from glandular trichomes in the leaves. When adult whiteflies were reared with fresh N. benthamiana leaves, they were completely dead within 84 h. Oral feeding of 20% N. benthamiana extracts using ethanol and water showed complete mortality of whiteflies within 48 hours. Spray of N. benthamiana extracts into the leaves was lethal to eggs but not to nymphs of whiteflies. Further, tomato plants sprayed with N. benthamiana extracts were highly repellent to adult whiteflies. Quantitative real-time PCR indicated that the expression of various genes of B. tabaci was changed by oral feeding of N. benthamiana extract. This study suggests N. benthamiana extract is a useful for the control of whiteflies and can be used as an alternative natural pesticide for the whitefly management.

Ghimire, Sushant,Lebek, Werner,Godehardt, Reinhold,Lee, Wan In,Adhikari, Rameshwar American Scientific Publishers 2016 Journal of nanoscience and nanotechnology Vol.16 No.5
<P>Owing to their wide applications in the field of optoelectronics, photonics, catalysis, and medicine; plasmonic metal nanoparticles are attaining considerable interest nowadays. The optical properties of these metal nanoparticles depend upon their size, shape, and surrounding medium. The present work studies the morphology and optical properties of bare silver nanoparticles and silica coated hybrid silver nanoparticles. Aqueous phase mediated synthesis and water-in-oil microemulsion mediated synthesis are two different wet chemical routes employed for nanosynthesis. Direct coating of silica is performed in water-in-oil microemulsion on pre-synthesized silver nanoparticles using tetraethyl orthosilicate as silica precursor. This study shows that using different wet chemical routes the size of the synthesized nanoparticles could be tuned. In addition, using reverse micelles as nanoreactors, the thickness of the silica shell around the core silver nanoparticles could be significantly controlled. Further, the optical properties of silver nanoparticles could be adjusted through the size and the surface coating.</P>
