Wheat Extract Oil (WEO) Attenuates UVB-Induced Photoaging via Collagen Synthesis in Human Keratinocytes and Hairless Mice
Authors: Son Dong Ju , Jung Jae Chul , Choi Yong Min , Ryu Hyeon Yeol , Lee Somin , Davis Barbara A.
Published: January 2020

The efficacy of wheat extract oil (WEO), standardized to glucosylceramides, for protecting against ultraviolet B (UVB)-induced damage of skin barrier function was assessed using the SHK-1 hairless mouse model and two human skin cell lines, namely, CCD-986sk and HeCaT. The ability of repeated oral administration of 30, 60, and 120 mg of WEO/kg/day for 12 weeks to prevent skin damage of SKH-1 hairless mice induced by UVB irradiation was evaluated. The results demonstrated that UVB-induced water evaporation (transepidermal water loss, TEWL) was significantly decreased by WEO. Similarly, UVB-induced losses in moisture and skin elasticity were improved by WEO supplementation. WEO attenuated the tissue procollagen type I, hyaluronic acid (HA), and ceramide reductions induced by UVB treatment as well. Collagen concentrations in skin tissue were increased in the WEO-treated mice, while UVB-induced epidermal thickening was reduced. In vitro studies using HeCaT human keratinocytes confirmed increased HA and collagen synthesis in response to WEO treatment. This may occur via WEO suppression of matrix metalloproteinase-1 (MMP-1), since its induction by UVB treatment was diminished in treated CCD-986sk cells. Oral administration of WEO improves skin barrier function in UVB-irradiated mice by attenuating damage typically observed in photoaging. This research further clarifies the clinical benefits previously observed by dietary WEO consumption.
The Effects of Gelatinized Wheat Starch and High Salt Diet on Gut Microbiota and Metabolic Disorder
Authors: Do Moon Ho , Lee Hye-Bin , Lee Eunjung , Park Ho-Young
Published: January 2020

Diets high in gelatinized starch and high in gelatinized starch supplemented with salt-induced metabolic disorders and changes in gut microbiota have scarcely been studied. In this study, mice on wheat starch diets (WD) exhibited significantly higher body weight, white adipose tissue (WAT), and gut permeability compared to those on normal diet (ND). However, gelatinized wheat starch diet (GWD) and NaCl-supplemented gelatinized wheat starch diet (SGW) mice did not increase body and WAT weights or dyslipidemia, and maintained consistent colon pH at ND levels. WD mice showed higher levels of Desulfovibrio, Faecalibaculum, and Lactobacillus and lower levels of Muribaculum compared to ND mice. However, GWD and SGW mice showed a significantly different gut microbial composition, such as a lower proportion of Lactobacillus and Desulfovibrio, and higher proportion of Faecalibaculum and Muribaculum compared to WD mice. High starch diet-induced dysbiosis caused increase of lipid accumulation and inflammation-related proteins’ expression, thereby leading to non-alcoholic fatty liver disease. However, GWD and SGW showed lower levels than that, and it might be due to the difference in the gut microbial composition compared to WD. Taken together, diets high in gelatinized starch and high in gelatinized starch supplemented with salt induced mild metabolic disorders compared to native starch.

Ted Chiang’s Asian American Amusement at Alien Arrival
Authors: Esaki Brett J.
Published: January 2020

In the 2016 movie Arrival, aliens with advanced technology appear on Earth in spaceships reminiscent of the black obelisk in 2001: A Space Odyssey. The film presents this arrival as a serious problem to be solved, with the future of human life and interplanetary relationships in the balance. The short story, “Story of Your Life” by Ted Chiang, on which the film was based, takes a different, amusing route that essentially depicts an ideal vision of the era of colonialism. To articulate this reading, this article will compare Chiang’s science fiction (SF) to the genre in general and will take Isiah Lavender III’s positionality of otherhood to reveal how Chiang’s work expresses a Chinese American secular faith in a moral universe. It will analyze the narrative form in Chiang’s collection, Stories of Your Life and Others, and will use it to compare the prose and film versions of “Story of Your Life.” It will also explain how Chiang may be using a nonlinear orthography and variational principles of physics to frame multileveled humor. It utilizes theories of humor by John Morreall and analyses of Chinese American secularity by Russell Jeung and concludes that Chiang’s work reflects concerns and trends of Asian Americans’ secularized religions.

Authors: Ackert Michael , Maglakelidze Erekle , Badurashvili Irina , Huber Stefan
Published: January 2020

This study presents the validation of the short forms of Centrality of Religiosity Scale (CRS) in Georgia. This country offers a unique Christian orthodox context with a long-lasting religious tradition and strong affiliation to churches. Translated short forms were administered in the years 2012 (CRS-5) and 2018 (CRSi-7). Participants reported on ideological, intellectual, and experiential aspects of their faith and their private and public religious practice in face-to-face interviews. The collected data was subject to reliability analyses. Scale invariance over time was tested with the CRS-5, whereas the CRSi-7 was examined for model goodness, with one factor—Centrality of Religiosity—with a confirmatory factor analysis. Derived statistical coefficients from large stratified random populational samples (2012: N = 2238 and 2018: N = 1906) show good to acceptable Cronbach’s α s ( α = 0.73 and α = 0.67). The composite scores’ means and standard deviations contour norm values for further investigations in social sciences related to religiosity in Georgia. The results of the confirmatory factor analyses show that the Centrality of Religiosity manifests a stable factor, adequately explaining different dimensions of faith life. The high reliability of the CRS-5 over time leads to the conclusion of consistent measurement characteristics and thus, its suitability for longitudinal analysis. The CRSi-7 has a comparable model fit to the CRS-5 providing an alternative for interreligious contexts if needed. Aspects of assessment and analysis are discussed and reasons for the application of the longer version of the CRS are provided in the end.

Published: January 2020

The recently emerged coronavirus in Wuhan, China has claimed at least six lives as of January 22 and infected hundreds if not thousands of individuals. The situation has drawn international attention, including from the virology community. We applaud the rapid release to the public of the genome sequence of the new virus by Chinese virologists, but we also believe that increased transparency on disease reporting and data sharing with international colleagues are crucial for curbing the spread of this newly emerging virus to other parts of the world.
The feasibility of measuring calprotectin from a throat swab as a marker of infections caused by group A streptococcus: a case–control feasibility study
Authors: Schofield Behnaz , Gregory Clive , Gal Micaela , Gillespie David , Naik Gurudutt , Hay Alastair , Francis Nick
Published: January 2020

Background

Most people with sore throat do not benefit from antibiotic treatment, but nearly three-quarters of those presenting in primary care are prescribed antibiotics. A test that is predictive of bacterial infection could help guide antibiotic prescribing. Calprotectin is a biomarker of neutrophilic inflammation, and may be a useful marker of bacterial throat infections.

Aim

To assess the feasibility of measuring calprotectin from throat swabs, and assess whether individuals with sore throats likely to be caused by streptococcal infections have apparently higher throat calprotectin levels than other individuals with sore throat and healthy volunteers.

Design & setting

A proof of concept case–control study was undertaken, which compared primary care patients with sore throats and healthy volunteers.

Method

Baseline characteristics and throat swabs were collected from 30 primary care patients with suspected streptococcal sore throat, and throat swabs were taken from 10 volunteers without sore throat. Calprotectin level determination and rapid antigen streptococcal testing were conducted on the throat swab eluents. Calprotectin levels in the following groups were compared: volunteers without a sore throat; all patients with a sore throat; patients with a sore throat testing either negative or positive for streptococcal antigen; and those with lower and higher scores on clinical prediction rules for streptococcal sore throat.

Results

Calprotectin was detected in all throat swab samples. Mean calprotectin levels were numerically higher in patients with sore throat compared with healthy volunteers, and sore throat patients who had group A streptococci antigen detected compared with those who did not.

Conclusion

Calprotectin can be measured from throat swab samples and levels are consistent with the hypothesis that streptococcal infection leads to higher throat calprotectin levels. This hypothesis will be tested in a larger study.

Authors: Haroon Maryiam
Published: January 2020

Industrial clusters and special economic zones are key areas of focus for industrial policy makers who are aiming to expand the industrial base and increase competitiveness. Thus, the role of development of industrial clusters in the productivity improvement of manufacturing firms merits attention. We use the firm-level Census of Manufacturing Industries (CMI) and Directory of Industries (DOI) datasets to empirically investigate the relationship between agglomeration and firm level total factor productivity for different sectors in Punjab, Pakistan. Our findings suggest that there is a correlation between localization, urbanization and total factor productivity of firms in the Punjab. However, the relationship varies by sectors, necessarily pointing industrial policy towards sector-specific recommendations.
Surplus Education and Earnings Differentials in Pakistan: A Quantile Regression Analysis
Authors: H. Sial Maqbool , Sarwar Ghulam , Saeed Mubashra
Published: January 2020

This study empirically investigates the effect of surplus education on the earnings distribution in Pakistan using quantile regression. The method of realized matches is used to measure the required level of education in each occupation from the Pakistan Social and Living Standards Measurement (PSLM) 2013-14 survey data. There is heterogeneity in returns to surplus education among overeducated workers. These returns are higher for workers at the upper half as compared to the lower half of the earnings distribution. Surplus education earns positive returns but less than the returns associated with the level of education required for jobs. Further, the difference in returns among the overeducated is higher than the difference in returns among workers who have the required education for the job. The findings imply that the surplus education factor is significant in explaining how education contributes in earnings differentials and inequality.

Electrical discharge machining (EDM) is one of the oldest nontraditional machining processes, commonly used in automotive, aerospace and ship building industries for machining metals that have high hardness, strength and to make complicated shapes that cannot be produced by traditional machining techniques. The process is based on the thermoelectric energy between the work piece and an electrode. EDM is slow compared to conventional machining, low material removal rate, high surface roughness, high tool wear and formation of recast layer are the main disadvantages of the process. Tool wear rate, material removal rate and surface quality are important performance measures in electric discharge machining process. Numbers of ways are explored by researchers for improving and optimizing the output responses of EDM process. The paper summarizes the research on die-sinking EDM relating to the improvements in the output response.

Water are one among the most indispensable and important things that we need in our day to day lives. We need to store water for drinking as well as to conduct our day to day chores efficiently. This will go a great way in managing the water tanks as the user will be aware of the water level in side this tank. This model can in future be implemented for the regular water tanks making their management an easy task. In future models we also hope to include the smart water management as well so that the water level is checked automatically ideally pumping water at low level and stopping at the full level. In android application we can monitoring the tank using motor on/off button manually.

Along with the advancement in Biomedical technology to cure many commons, but there is certain lethal disease spanned in the world which has no cure for it. One such is Diabetes, although it does not have any remedy, at least it has controlling and diagnosing methods. It is a type of disorder in body metabolism where there is a high blood sugar level for sustained period. Diabetes is a condition in which there happened to be high blood sugar levels over a longtime. Symptoms are repeated urination, thirst, and hunger. If left unchecked, it may cause many complications. Acute complications include ketoacidosis, or death. The Diabetes can be analysed by gaining a drop of blood from test subject and blending it with biosensor. This method is compact and modest, but it happens to be an intrusive and contaminant method as it deals with the usage of blood. This assumption sparked us to progress a non-invasive method of diagnosing the diabetes level for a patient using their foot sensitivity. This advancement helps one to obtain the same test result but with a non-invasive practise, which gives a painless and non-contaminant diagnosis.

The aim of this project is to segregate the fiber from agricultural waste in three distinct stages such as alkali treatment, bleaching process, acid hydrolysis. Agricultural wastes such as cassava bagasse, sorghum stalk, corn stalk were selected. Initially the raw materials were subjected to chemical processes like alkali treatment and bleaching process to remove lignin and hemi cellulose. The chemically purified cellulose was then subjected to acid hydrolysis for isolation of fiber. Characterization of FTIR result shows that hemicellulose and lignin was partially eliminated. TGA was carried to know the thermal properties of the sample. The film was formed by casting method using isolated fiber, maize starch, agar, Tween 80. The fibers were incorporated into the film and their properties such as tensile strength, moisture content and solubility were studied

Knowledge on interactions between earthworms and microbes at molecular level has been obscure. Mechanism by which earthworms defend themselves against different microorganisms in the soil is largely unknown. Coelomic fluid from earthworm species has been shown to have antimicrobial activity. In this study we report that coelomic fluid isolated from Eudrilus eugeniae has antifungal activity against four different phytopathogens such as Rhizoctonia solani, Fusarium oxysporum, Aspergillus flavus and Verticillium dahlia. Incubation of coelomic fluid with fungal hyphae of all these four strains for 12 hours revealed that the growth of hyphae was greatly inhibited. Light microscopy studies confirmed that the hyphae growth was greatly reduced by incubation of coelomic fluid. Analysis of the fluid in the microscope showed the presence of different types of coelomocytes in the mucous fluid. Other molecules and compounds in the coelomic fluid might also have played role in antifungal activity.

In this manuscript, we discuss the designing procedure of chain sampling plan which is known as one of the conditional sampling plans under gamma-Poisson distribution. We determine the optimal parameters namely, number of items to be chosen for inspection from the lot and number of preceding lots to be considered in order to dispose the current lot by specifying two points on the operating characteristic curve, which is the usual designing approach of sampling plan. The procedure which is used to execute the proposed plan is provided and comparison is made among the proposed plan and existing sampling plans performance.
