IntroductionThe global and ongoing COVID-19 outbreak has compelled the need for timely and reliable methods of detection for SARS-CoV-2 infection. Although reverse transcription-polymerase chain reaction (RT-PCR) has been widely accepted as a reference standard for COVID-19 diagnosis, several early studies have suggested the superior sensitivity of computed tomography (CT) in identifying SARS-CoV-2 infection. In a previous systematic review, we stratified studies based on risk for bias to evaluate the true sensitivity of CT for detecting SARS-CoV-2 infection. This study revisits our prior analysis, incorporating more current data to assess the sensitivity of CT for COVID-19.Material and methodsThe PubMed and Google Scholar databases were searched for relevant articles published between 1 January 2020, and 25 April 2021. Exclusion criteria included lack of specification regarding whether the study cohort was adult or paediatric, whether patients were symptomatic or asymptomatic, and not identifying the source of RT-PCR specimens. Ultimately, 62 studies were included for systematic review and were subsequently stratified by risk for bias using the QUADAS-2 quality assessment tool. Sensitivity data were extracted for random effects meta-analyses.ResultsThe average sensitivity for COVID-19 reported by the high-risk-of-bias studies was 68% [CI: 58, 80; range: 38-96%] for RT-PCR and 91% [CI: 87, 96; range: 47-100%] for CT. The average sensitivity reported by the low-risk-of-bias studies was 84% [CI: 0.75, 0.94; range: 70-97%] for RT-PCR and 78% [CI: 71, 0.86; range: 44-92%] for CT.ConclusionsOn average, the high-risk-of bias studies underestimated the sensitivity of RT-PCR and overestimated the sensitivity of CT for COVID-19. Given the incorporation of recently published low-risk-of-bias articles, the sensitivities according to low-risk-of-bias studies for both RT-PCR and CT were higher than previously reported.

Manusia menjalani hampir sebagian hidupnya di tempat tidur. Pada umumnya tinggal di tempat tidur tidak menimbulkan masalah justru akan timbul masalah jika manusia tidak cukup istirahat (istirahat malam). Selama tidur manusia membangun kembali energinya. Masalah akan timbul jika seseorang yang sedang menderita penyakit terlalu lama beristirahat di tempat tidur. Berdasarkan pengalaman peneliti pada saat melakukan survey di RSU Artha Medica Binjai Tahun 2020, masih ada pasien tirah baring yang mengalami dekubitus. Hal ini dikarenakan tingginya beban perawat, sementara pasien tirah baring sangat ketergantungan dengan perawat, oleh karna itu pengetahuan seorang perawat dalam mencegah terjadinya kejadian dekubitus sangat penting tentang pergantian posisi saat berbaring di tempat tidur, dari 55 perawat. Berdasarkan dari hasil penelitian kepada perawat yang dilakukan di RSU Artha Medica Binjai Tahun 2020 didapati ada hubungan antara tingkat pengetahuan perawat tentang pasien tirah baring dengan kejadian dekubitus (0,000 < 0,05) dengan besar korelasi antar variabel adalah 0,000 berarti Ho ditolak Ha diterima. Hal ini membuktikan bahwa hubungan antar tingkat pengetahuan perawat tentang pasien tirah baring dengan kejadian dekubitus memiliki tingkat pengetahuan yang positif.

Published: August 2022

Abstract. The members of the monoacylglycerol acyltransferase (MOGAT) family are essential candidate genes that influence economic traits associated with triglyceride synthesis, dietary fat absorption, and storage in livestock. In addition, the MOGAT gene family may also play an essential function in human polygenic diseases, like type 2 diabetes and obesity. The present study was conducted on Holstein calves to find the association between MOGAT1, MOGAT3/g.A229G, and MOGAT3/g.G1627A and growth traits. The polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) method was performed for genotyping the MOGAT1, MOGAT3/g.A229G, and MOGAT3/g.G1627A genes' locus using the TaqI, MspI, and BsuRI restriction enzyme. The allele frequency of A and G of the MOGAT1 locus was 0.79 and 0.21, respectively, while the genotype frequency was 0.65, 0.28, and 0.07 for AA, AG, and GG, respectively. While the allele and genotype frequencies of the MOGAT3/g.A229G locus were 00.57(A1), 0.43(G1), 0.35(A1A1), 0.45(A1G1), and 0.20(G1G1), the allele and genotype frequencies of the MOGAT3/g.G1627A locus were 0.49(A2), 0.51(G2), 0.25(A2A2), 0.49(A2G2), and 0.26(G2G2). Chi-square analysis showed that MOGAT3/g.G1627A distribution was at the Hardy–Weinberg disequilibrium (p < 0.05), and MOGAT1 and MOGAT3/g.A229G distribution was at the Hardy–Weinberg equilibrium (p > 0.05). In total, two statistical methods (general linear model (GLM) and PROC MIXED) were used to identify an association between gene locus and growth traits. An association analysis showed a statistically significant difference between the MOGAT1 and body weight, body length, and chest circumference, MOGAT3/g.A229G with average daily gain (ADG) and withers height, and MOGAT3/g.G1627A with body weight and body length (p < 0.05). The results confirmed that the MOGAT1, MOGAT3/g.A229G, and MOGAT3/g.G1627A locus are strong candidate genes that could be considered molecular markers for growth traits in cattle breeding.

Abstract. We use the Weather Research and Forecasting with Chemistry (WRF-Chem) model
with new implementations of GOES-16 wildfire emissions and plume rise based on fire radiative power (FRP)
to interpret aerosol observations during
the 2019 NASA-NOAA FIREX-AQ field campaign and perform model evaluations. We
compare simulated aerosol concentrations and optical properties against
observations of black carbon aerosol from the NOAA Single Particle Soot
Photometer (NOAA-SP2), organic aerosol from the CU High-Resolution Aerosol
Mass Spectrometer (HR-AMS), and aerosol backscatter coefficients from the
high-spectral-resolution lidar (HSRL) system. This study focuses on the
Williams Flats fire in Washington, which was repeatedly sampled during four
science flights by the NASA DC-8 (3–8 August 2019). The emissions
and plume-rise methodologies are implemented following NOAA's operational
High-Resolution Rapid Refresh coupled with Smoke (HRRR-Smoke) forecasting
model. In addition, new GOES-16 FRP-based diurnal cycle functions are
developed and incorporated into WRF-Chem. The FIREX-AQ observations
represented a diverse set of sampled environments ranging from fresh/aged
smoke from the Williams Flats fire to remnants of plumes transported over
long distances. The Williams Flats fire resulted in significant aerosol
enhancements during 3–8 August 2019, which were substantially
underestimated by the standard version of WRF-Chem. The simulated black carbon (BC) and organic carbon (OC)
concentrations increased between a factor of 92–125 (BC) and a factor of 28–78 (OC)
with the new implementation compared to the standard WRF-Chem version. These
increases resulted in better agreement with the FIREX-AQ airborne
observations for BC and OC concentrations (particularly for fresh smoke
sampling phases) and aerosol backscatter coefficients. The model still
showed a low bias in simulating the aerosol loadings observed in aged plumes
from Williams Flats. WRF-Chem with the FRP-based plume rise simulated similar
plume heights to the standard plume-rise model in WRF-Chem. The simulated
plume heights (for both versions) compared well with estimated plume heights
using the HSRL measurements. Therefore, the better agreement with
observations was mainly driven by the higher emissions in the FRP-based
version. The model evaluations also highlighted the importance of accurately
accounting for the wildfire diurnal cycle and including adequate
representation of the underlying chemical mechanisms, both of which could
significantly impact model forecasting performance.
Compilation of Southern Ocean sea-ice records covering the last glacial-interglacial cycle (12–130 ka)

Published: August 2022

Abstract. Antarctic sea ice forms a critical part of the Southern
Ocean and global climate system. The behaviour of Antarctic sea ice
throughout the last glacial-interglacial (G-IG) cycle (12 000–130 000 years) allows us to investigate the interactions between sea ice and climate under
a large range of mean climate states. Understanding both temporal and
spatial variations in Antarctic sea ice across a G-IG cycle is crucial to a
better understanding of the G-IG regulation of atmospheric CO2, ocean
circulation, nutrient cycling and productivity. This study presents 28
published qualitative and quantitative estimates of G-IG sea
ice from 24 marine sediment cores and an Antarctic ice core. Sea
ice is reconstructed from the sediment core records using diatom assemblages and from the ice core record using sea-salt sodium flux. Whilst all regions of the Southern Ocean display the same overall pattern in G-IG sea-ice variations, the magnitudes and timings vary between regions. Sea-ice cover is most sensitive to changing climate in the regions of high sea-ice outflow
from the Weddell Sea and Ross Sea gyres, as indicated by the greatest
magnitude changes in sea ice in these areas. In contrast the Scotia Sea
sea-ice cover is much more resilient to moderate climatic warming, likely
due to the meltwater stratification from high iceberg flux through “iceberg alley” helping to sustain high sea-ice cover outside of full glacial intervals. The differing sensitivities of sea ice to climatic shifts between
different regions of the Southern Ocean has important implications for the
spatial pattern of nutrient supply and primary productivity, which
subsequently impact carbon uptake and atmospheric CO2 concentrations
changes across a G-IG cycle.

Abstract. A new ice core was drilled in West Antarctica on Skytrain Ice Rise in field season 2018/2019. This 651 m ice core is one of the main targets of the WACSWAIN (WArm Climate Stability of the West Antarctic ice sheet in the last INterglacial) project. A present-day accumulation rate of 13.5 cm w.e. yr−1 was derived. Although the project mainly aims to investigate the last interglacial (115–130 ka), a robust chronology period covering the recent past is needed to constrain the age models for the deepest ice. Additionally, this time period is important for understanding current climatic changes in the West Antarctic region. Here, we present a stratigraphic chronology for the top 184.14 m of the Skytrain ice core based on absolute age tie points interpolated using annual layer counting encompassing the last 2000 years of climate history. Together with a model-based depth–age relationship of the deeper part of the ice core, this will form the ST22 chronology. The chemical composition, dust content, liquid conductivity, water isotope concentration and methane content of the whole core was analysed via continuous flow analysis (CFA) at the British Antarctic Survey. Annual layer counting was performed by manual counting of seasonal variations in mainly the sodium and calcium records. This counted chronology was informed and anchored by absolute age tie points, namely, the tritium peak (1965 CE) and six volcanic eruptions. Methane concentration variations were used to further constrain the counting error. A minimal error of ±1 year at the tie points was derived, accumulating to ± 5 %–10 % of the age in the unconstrained sections between tie points. This level of accuracy enables data interpretation on at least decadal timescales and provides a solid base for the dating of deeper ice, which is the second part of the chronology.

Artist Statement: This cover is meant to reflect Asia's chaos, warmth, and ebullience. The streets packed with cars, the confluence of traditional and modern architecture — for me, these are defining characteristics of this expansive and nebulous continent. As for the butterflies, they symbolize new beginnings and migration, a metaphor for both the widespread Asian diaspora and the birth of the CJA itself.

Perspectives on NFTs from the EU and UK
Authors: Guadamuz Andres 
Published: August 2022

I want to start with a bit of a disclaimer: I have actually minted, bought, and sold a few NFTs. But I’ve managed only to lose money. I think I am not alone. There is a report in Nature says that that some 75% of all NFT sales have been for under fifteen dollars.
I could spend hours talking about the common pitfalls and issues faced by EU and UK participants in the NFT market. There are many different topics up for discussion, but I have selected just a few that I find might be different from an international perspective when compared with the experience in the United States. You may have noticed that I’m separating the UK and European perspectives. (Thank you, Brexit.) There has already been much talk about what you are getting when you purchase an NFT: The data is a smart contract. It is code. In other words, the NFT is not the artwork, it is just the token that represents the work. But we have not really explored how copyright law impacts the NFT market. So, the first question I want to explore is the rights question.

In modern years, there has been a large dealing of work toward the area of free radical chemistry. Free radicals reactive oxygen species and reactive nitrogen species are create by our body by various endogenic systems, influence to different physio chemical conditions or unhealthy states. A balance between free radicals and antioxidants is necessary for proper physiological function. If free radicals overwhelm the body's ability to modulate them, a condition known as oxidative stress ensues. Free radicals thus unfavorable alter lipids, proteins, and DNA and activate a number of human diseases. Hence application of external source of antioxidants can assist in coping this oxidative stress. Synthetic antioxidants such as butylated hydroxytoluene and butylated hydroxyanisole have recently been reported to be dangerous for human health. The present review provides a brief overview on oxidative stress mediate cellular damages and role of dietary antioxidants as functional foods in the organization of human diseases. We need to take balance diet which provide much more antioxidants to lower risks of health and run to life longer.The purpose of this review is that we want awareness related to sources of antioxidants from plants and highlight the studies of antioxidants and free radicals which provide prove for maintaining healthy aging.
Key words: antioxidant, free radicals, aging, oxidative stress.

Decoding of a Gendered Marginalized Discourse in V.S. Naipaul’s A House for Mr. Biswas
Authors: Rehman Muhammad Shakil Ur , Chattha Saima Akhter , Niazi Zia Ullah Khan 
Published: August 2022

Focusing on Sara Mill’s Feminist stylistics in A House for Mr. Biswas (1961) by V.S. Naipaul (1961), the article provides an alternative understanding of the novel through the lens of the undertaken framework to reveal marginalization on gender basis. The disparity of the socio- cultural roles of men and women in the novel through a particular use of language divulges gender inequality in a society. The preference of masculinity engrossed in of preferable patriarchal titles, names, generic pronouns and professions leads to a gender labeling. The disparaging portrayal of women in the fictional representation of a postcolonial work manifests that women are discriminated against. It is substantial, therefore, to problematize gender representation through the application of “toolkit” (Mills, 1995, p.2). It is also one of the significant theoretical frameworks that critiques a literary piece to unearth concealed objectives wrought in an implicit and explicit language-use. Naipaul in the selected work represents through a language use - word, phrase/sentence, discourse to demonstrate how rampant socio-cultural gender norms play a pivotal role in upholding gender inequality. Therefore, the study concludes that submissive role of women through the specific use of discourse makes the application of feminist stylistics more pertinent to highlight the stereotypical gender norms that are used to strengthen patriarchal hegemony. Hence, socio-cultural gender norms with the collusion of a specific discourse used in the novel are coded for dominance of patriarchy and segregation of women subsequently.
