Published: November 2021

The clinical data on the biologic disease-modifying antirheumatic drug (bDMARD) use in late-onset ankylosing spondylitis (LOAS) is limited. Thus, this study aimed to evaluate the drug efficacy and retention rate of bDMARDs in LOAS and compare it to young-onset ankylosing spondylitis (YOAS). Data of patients with AS receiving bDMARDs were extracted from the Korean College of Rheumatology Biologics and Targeted Therapy registry. Patients whose age of onset was > 50 years and ≤ 50 years were classified as having LOAS and YOAS, respectively. Their baseline characteristics and disease-associated parameters were evaluated. Drug efficacy [Ankylosing Spondylitis Disease Activity Score (ASDAS)-clinically important improvement (CII), ASDAS-major improvement (MI), Assessment of SpondyloArthritis International Society (ASAS) 20, and ASAS 40] at 1-year follow-up and drug retention rates were assessed. A total of 1708 patients (comprising 1472 patients with YOAS and 236 patients with LOAS) were included in this analysis. The LOAS group had a lower prevalence among males, lower HLA-B27 positivity and a higher prevalence of peripheral arthritis. Patients with LOAS were more likely to have higher disease-associated parameters (inflammatory reactants, patient global assessment, ASDAS-erythrocyte sedimentation rate, and ASDAS-C-reactive protein). LOAS was negatively associated with achieving ASDAS-CII, ASAS 20, and ASAS 40. The drug retention rate was lower in LOAS; however, the propensity score-matched and covariate-adjusted hazard ratios for bDMARD discontinuation were comparable to YOAS. There were no differences in the drug retention rates based on the type of bDMARD used in LOAS. Inferior clinical efficacy and shorter drug retention time were found in patients with LOAS receiving bDMARDs using real-world nationwide data. There were no differences among each bDMARD type.

Published: November 2021

B-cell lymphoma2 (Bcl-2)-associated athanogene (BAG) family proteins are evolutionary conserved across all eukaryotes. These proteins interact with HSP70/HSC70 and function as co-chaperones during stress response and developmental pathways. Compared to the animal counterpart, the BAG proteins in plants are much less studied and primarily Arabidopsis BAG proteins have been identified and characterized for their role in programmed cell death, homeostasis, growth and development, abiotic and biotic stress response. Here, we have identified BAG protein family (SlBAGs) in tomato, an economically important and a model fruit crop using genome-wide scanning. We have performed phylogenetic analysis, genes architecture assessment, chromosomal location and in silico promoter analysis. Our data suggest that SlBAGs show differential tissue specific expression pattern during plant development particularly fruit development and ripening. Furthermore, we reported that expression of SlBAGs is modulated during abiotic stresses and is regulated by stress hormones ABA and ethylene. In planta subcellular localization reveals their diverse subcellular localization, and many members are localized in nucleus and cytoplasm. Like previous reports, our protein–protein interaction network and yeast two-hybrid analysis uncover that SlBAGs interact with HSP70. The current study provides insights into role of SlBAGs in plant development particualry fruit ripening and abiotic stress response.

Published: November 2021

Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) share some similar pathological mechanisms. In current study, we intend to investigate the impact of AR on CRS. In addition, we explored the efficacy of erythromycin (EM) treatment on CRS mice with or without AR (CRSwoAR, CRSwAR). Study subjects were divided into control, CRSwoAR, and CRSwAR groups. Experimental mice were divided similarly into control, CRSwoAR, and CRSwAR groups. In addition, CRS mice were treated with EM at 0.75, 7.5, or 75 mg/kg or with dexamethasone (Dex) at 1 mg/kg. In our results, allergy exacerbates inflammation that was evident in nasal histology and cytokine expression both in patients and in mice with CRS. Dex 1 mg/kg, EM 7.5 or 75 mg/kg treatments significantly inhibited serum IgE and IgG2a in CRS mice. EM-treated CRS mice had significantly elevated IL-10 levels and had a reversal of Th-1/Th-2 cytokine expression in nasal-associated lymphoid tissue. MUC5AC expressions were significantly reduced in the 7.5 or 75 mg/kg EM-treated mice compared with untreated mice. EM showed inhibitions on immunoglobulin production and mucus secretion stronger than Dex. We concluded that comorbid AR enhanced inflammation of CRS. EM and Dex treatments showed similar anti-inflammatory effects on CRS but through partly different mechanisms.

Published: November 2021

Antarctica plays a fundamental role in the Earth's climate, oceanic circulation and global ecosystem. It is a priority and a scientific challenge to understand its functioning and responses under different scenarios of global warming. However, extreme environmental conditions, seasonality and isolation hampers the efforts to achieve a comprehensive understanding of the physical, biological, chemical and geological processes taking place in Antarctica. Here we present unmanned aerial vehicles (UAVs) as feasible, rapid and accurate tools for environmental and wildlife research in Antarctica. UAV surveys were carried out on Deception Island (South Shetland Islands) using visible, multispectral and thermal sensors, and a water sampling device to develop precise thematic ecological maps, detect anomalous thermal zones, identify and census wildlife, build 3D images of geometrically complex geological formations, and sample dissolved chemicals (< 0.22 µm) waters from inaccessible or protected areas.

Authors: Takeuchi Kosuke , Akizuki Kazunori , Nakamura Masatoshi
Published: November 2021

The purpose of the present study was to examine the association between static stretching load and changes in the flexibility of the hamstrings. Twelve healthy men received static stretching for 60 s at two different intensities based on the point of discomfort (100%POD and 120%POD intensity), in random order. To assess the flexibility of the hamstrings, the knee extension range of motion (ROM). Passive torque at end ROM, and muscle–tendon unit stiffness were measured before and after stretching. The static stretching load was calculated from the passive torque throughout static stretching. The knee extension ROM and passive torque at end ROM increased in both intensities (p < 0.01). The muscle–tendon unit stiffness decreased only in the 120%POD (p < 0.01). There were significant correlations between the static stretching load and the relative changes in the knee extension ROM (r = 0.56, p < 0.01) and muscle–tendon unit stiffness (r = − 0.76, p < 0.01). The results suggested that the static stretching load had significant effects on changes in the knee extension ROM and muscle–tendon unit stiffness of the hamstrings, and high-intensity static stretching was useful for improving the flexibility of the hamstrings because of its high static stretching load.

Group A rotaviruses (RVA) remain a leading cause of pediatric diarrhea worldwide, in part due to underperformance of currently approved live-attenuated, oral vaccines in low-and-middle income countries. Improved immune correlates of protection (CoP) for existing oral vaccines and novel strategies to evaluate the performance of next-generation vaccines are needed. Use of oral vaccines as challenge agents in controlled human infection models is a potential approach to CoP discovery that remains underexplored. In a live-attenuated, oral rotavirus vaccine (Rotarix, GlaxoSmithKline) efficacy trial conducted among infants in Dhaka, Bangladesh, we explored the potential for the second dose of the two-dose series to be considered a challenge agent through which RVA immunity could be explored, using fecal virus shedding post-dose 2 as a marker of mucosal immunity. Among 180 vaccinated infants who completed the parent study per protocol, the absence of fecal vaccine shedding following the second dose of Rotarix suggested intestinal mucosal immunity generated by the first dose and a decreased risk of RVA diarrhea through 2 years of life (RR 0.616, 95% CI 0.392–0.968). Further development of controlled human infection models for group A rotaviruses, especially in prospective studies with larger sample sizes, may be a promising tool to assess rotavirus vaccine efficacy and CoPs.

Published: November 2021

Proliferation of multidrug-resistant (MDR) bacteria poses a threat to human health, requiring new strategies. Here we propose using fitness neutral gene expression perturbations to potentiate antibiotics. We systematically explored 270 gene knockout-antibiotic combinations in Escherichia coli, identifying 90 synergistic interactions. Identified gene targets were subsequently tested for antibiotic synergy on the transcriptomic level via multiplexed CRISPR-dCas9 and showed successful sensitization of E. coli without a separate fitness cost. These fitness neutral gene perturbations worked as co-therapies in reducing a Salmonella enterica intracellular infection in HeLa. Finally, these results informed the design of four antisense peptide nucleic acid (PNA) co-therapies, csgD, fnr, recA and acrA, against four MDR, clinically isolated bacteria. PNA combined with sub-minimal inhibitory concentrations of trimethoprim against two isolates of Klebsiella pneumoniae and E. coli showed three cases of re-sensitization with minimal fitness impacts. Our results highlight a promising approach for extending the utility of current antibiotics.

Published: November 2021

In the non‐effectively grounding distribution system, residual current under single‐line‐to‐ground (SLG) fault threatens the safety of human being and power supply equipment. Active arc suppression device has been proved to be effective for SLG fault arc suppression when the line impedance is ignored. However, in practice, line impedance varies with the fault location and the load current flowing through the impedance brings about additional voltage drop, which increases the fault current and is not dealt with by the conventional methods. To achieve accurate SLG fault arc suppression with the existence of line impedance, the neutral‐to‐ground voltage reference for full ground‐fault current compensation is firstly derived and a detection method is then proposed. The pre‐fault and post‐fault line currents are used to eliminate the influence of load current on the line impedance voltage drop. A dual‐loop voltage and current controller is then designed. The prototype of active arc suppression device was developed. The results of simulation and prototype experiment validate the effectiveness of the proposed method.
Sensitivity of back‐projection algorithm (BPA) synthetic aperture radar (SAR) image formation to initial position, velocity, and attitude navigation errors
Authors: Lindstrom Colton , Christensen Randall , Gunther Jacob , Jenkins Scott
Published: November 2021

The Back‐Projection Algorithm (BPA) is a time‐domain‐matched filtering technique to form synthetic aperture radar (SAR) images. To produce high‐quality BPA images, precise navigation data for the radar platform must be known. Errors in position, velocity, or attitude result in improperly formed images that are corrupted by shifting and blurring. The contribution of this paper is the development of analytical expressions that characterise the relationship between navigation errors and image formation errors from an inertial navigation point of view, where trajectory estimation errors in position, velocity, and attitude propagate through time and cause compounding errors in the vehicle state vector. These analytical expressions are verified via simulated image formation and real‐data image formation.

AT2019wey is a transient discovered by the Asteroid Terrestrial-impact Last Alert System survey in December of 2019. Follow-up optical, radio, and X-ray observations led to classification of this source as a Galactic black hole X-ray binary candidate. We carried out one-epoch 6.7 GHz European Very Long Baseline Interferometry Network and two-epoch multi-frequency (1.6, 4.5, 6.7 GHz) Very Long Baseline Array observations within a year after its discovery. These observations reveal a fading and flat-spectrum radio source with no discernible motion. These features suggest the detection of a compact jet. The source appears resolved at milliarcsecond scales, and the source angular size versus frequency trend is consistent with scatter broadening. This allows us to constrain the lower limit of the source distance to 6 kpc if the scattering medium is in a Galactic spiral arm. For a source location at greater than 3 kpc, the estimated upper limit of the peculiar velocity suggests the asymmetric natal kick may have occurred during the black hole formation stage.

Published: November 2021

The Covid 19 pandemic has an impact on young farmer entrepreneurs. Business income has dropped drastically, and the distribution process is experiencing difficulties. Entrepreneurial behaviour is needed so that young farmers can cope with the impact of Covid 19. This research seeks to analyze the entrepreneurial behaviour of young farmers during the Covid 19 period. The sample is all educated young farmers who participated in the PWMP program (Agricultural Young Entrepreneur Development)—using a google form from 90 participants who were willing to fill out 71 young farmers. The research variables were: the ability to survive in entrepreneurship (X1), the use of new media for entrepreneurship (X2), and business success during the Covid period (X3). Percentage, mean score, and regression analysis at p ≤ 0.05 were employed to analyze the data. There was a significant effect (p ≤ 0.05) between X1 and X2 on X3 of 28.1%. The ability to survive in entrepreneurship (X1) has a significant effect, while new media for entrepreneurship (X2) is insignificant. The government is expected to protect young farmers' businesses by providing additional capital, marketing and business assistance in collaboration with successful entrepreneurs.

Published: November 2021

New Superior Varieties (VUB) is a cultivation technology innovation that is continuously being developed by Balitbangtan. The average production addition of inbred rice seed is about 1.5% per year. Inbred rice varieties include Inpari 62 varieties, Inpago 18 varieties, and Inpara 11 varieties. Currently, farmers have used 25 varieties of Inpari, and 5 varieties of Inpago. This means that the use of VUB at the farm level is not optimal yet. Therefore, the aim of this paper is to determine the determinants of VUB adoption in the rice productivity improvement program. Data were collected using a questionnaire filled out via google form from 30 BPTP. Respondents consisted of 180 researchers and 113 extension workers. Data were analyzed using Analytical Hierarchy Process. The results of the analysis showed that the success of VUB adoption is influenced by determinants such as: (i) the nature of VUB innovation according to farmers' preferences, (ii) easy seed distribution and (iii) dissemination by improving technical guidance. The use of VUB can be increased by taking into account: (i) user preferences and according to the location of planting, and (ii) involving local breeders in overcoming availability and serving as a pilot location.

Fertilizer price subsidies aim to increase the purchasing power of poor farmers in order to increase their productivity and farm income. This study aims to analyze the urgency of the fertilizer subsidy policy, and the development of the subsidized fertilizer HET ratio and the price of grain at the farmer level. The study was conducted in West Java Province, 2020. The data used include primary data and secondary data. Data analysis was carried out quantitatively and descriptively qualitatively. The results showed that the fertilizer subsidy policy was given to farmers who farmed a maximum of 2 hectares per season. In Indonesia, the total number of households using land with a scale of < 2 ha reaches 89%, which are small farmers and require input subsidies. Furthermore, the ratio of output prices to urea fertilizer (2012-2021) tends to increase by 0.97%/year. This shows that the development of subsidized fertilizer prices is relatively small compared to the development of government purchasing prices for paddy. Therefore, in order to improve the efficiency of fertilizer use and maintain the volume of subsidized fertilizer in the midst of a limited fertilizer subsidy budget, efforts must be made to be more targeted and efficient.

The Indonesian government has implemented a solar panel policy to overcome a limitation of electrical availability in remote islands. Unfortunately, the prior studies have given a little concern to examine the social effect of the policy. Therefore, this paper addresses the research gap by testing the difference in social impacts of solar cell usage. Before and after analysis was used in this study. This research was conducted using a survey approach on two rural coastal communities in Karimun Regency, Kepulauan Riau, Indonesia. The research was arranged from May to October 2019. The respondent was chosen using simple random sampling. 262 respondents from these regions were voluntarily involved in the survey. Data were analysed using descriptive statistics and a paired sample t-test by applying SPSS. The findings reveal that there are significant differences in communities’ social capital in terms of social relationships, trust, participation in the community, and brotherhood, before and after the policy is applied. Although solar panels provide many conveniences to society, social capital decreases to a lower level than before. The contributions of the research to the theory and practice are discussed.

There have been numerous literatures on sustainable forest management and its relation to sustainable development goals. However, the comparative studies on regulatory framework and initiatives for realizing Sustainable Development Goals (SDGs) and sustainable forest management remain underexplored, particularly with the recent development of legal systems and policy in Malaysia and Indonesia. This research aims to identify and compare the regulatory framework and government initiatives in Malaysia and Indonesia for the realization of SDGs with special reference to sustainable forest management by addressing deforestation and other relevant problems. The research shows that in developing the SDGs, the Indonesian government tends to overlap in formulating its regulations. The majority of initiatives built before and after implementing a sustainable forest management model in Indonesia are very much in line with what the SDGs has been aspired. The cause of the decline in forest management in Indonesia is the regulation that made beyond the realm of forest management. The vision and attempt of the Malaysian government, on the other hand, to achieve sustainable development status by 2020 are stated clearly but the results remain debateable which is similar to those of Indonesia.
