    Abstract Background: A newly emergent strain of coronavirus (COVID-19) has affected almost the whole of the world's population. Currently, there is no specific vaccine or drug against COVID-19. Xu et al. (2020) built a homolog model of SARS-CoV-2 Mpro based on SARS-CoV Mpro, which is considered as a target to inhibit the replication of CoV.
    Objective: The aim of the current study was to find potential inhibitors of COVID-19 Mpro using docking analysis.
    Methods: Autodockvina was used to carry out Protein-Ligand docking. COVID-19 main protease Mpro was docked with catechin and its different synthetic derivatives. Nelfinavir, an antiretroviral drug belonging to protease inhibitors, was taken as the standard.
    Results: According to the result obtained, it was found that Compound (4) and Compound (1) have more affinity than nelfinavir.
    Conclusion: Compounds were found to have a great potential to become COVID-19 main protease Mpro inhibitor. Nevertheless, for their medicinal use, further investigation is necessary.

    Abstract The increased demand for energy in agriculture raised the cost of production and hence caused greenhouse gas emissions. Therefore, improving energy efficiency is essential to decrease energy demand and, consequently, reduce costs and reduce greenhouse gas emissions. The objective of this study was to compute energy efficiency and assess the influence of technological innovation on technically computed energy efficiency of the agricultural sector in South Asia. A two-stage analysis was carried out using panel data over the period 2002–2019. First, energy efficiency was computed employing the stochastic frontier analysis (SFA) approach. Second, the influence of technological innovation on technically derived energy efficiency was examined employing a system generalized method of moments (GMM) approach. Findings of the SFA approach show that the average energy efficiency of the South Asian agricultural sector was 84%, ranging from 79 to 86%, showing that there is still 16% room for improvements in energy efficiency of the agriculture in South Asia. In addition, this study found that India has relatively high energy efficiency (86%) compared to other countries in South Asia. The study also found that energy efficiency shows a slight upward trend in the agricultural sector in South Asia. The findings of the system GMM revealed that technological innovation is playing a significant role in improving energy efficiency of the agricultural sector in South Asia. Based on our findings, South Asia can reduce energy inefficiency by spending more on research and development (R&D) in the agricultural sector.

    Abstract Non-coding RNAs (ncRNAs) can control the flux of genetic information; affect RNA stability and play crucial roles in mediating epigenetic modifications. A number of studies have highlighted the potential roles of both virus-encoded and host-encoded ncRNAs in viral infections, transmission and therapeutics. However, the role of an emerging type of non-coding transcript, circular RNA (circRNA) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has not been fully elucidated so far. Moreover, the potential pathogenic role of circRNA-miRNA-mRNA regulatory axis has not been fully explored as yet. The current study aimed to holistically map the regulatory networks driven by SARS-CoV-2 related circRNAs, miRNAs and mRNAs to uncover plausible interactions and interplay amongst them in order to explore possible therapeutic options in SARS-CoV-2 infection. Patient datasets were analyzed systematically in a unified approach to explore circRNA, miRNA, and mRNA expression profiles. CircRNA-miRNA-mRNA network was constructed based on cytokine storm related circRNAs forming a total of 165 circRNA-miRNA-mRNA pairs. This study implies the potential regulatory role of the obtained circRNA-miRNA-mRNA network and proposes that two differentially expressed circRNAs hsa_circ_0080942 and hsa_circ_0080135 might serve as a potential theranostic agents for SARS-CoV-2 infection. Collectively, the results shed light on the functional role of circRNAs as ceRNAs to sponge miRNA and regulate mRNA expression during SARS-CoV-2 infection.

    Abstract Experiments were conducted to evaluate the effect of rhizobial inoculums and inorganic fertilizers on NP availability, soil microbial activity, wheat NPK concentration and uptake. These experiments were consisted of two factors, four inoculums (no, lentil, peas, and chickpeas) and two NPK doses (120:90:60 and 96:72:48 kg ha⁻¹). Inoculums significantly increased plant total NPK concentration by 39, 57, and 37%, and their uptake by 66, 86, and 56%, respectively. Peas inoculum was most efficient in wheat NPK concentration and uptake. The interactive effect of inoculums and NPK demonstrated that peas and lentil inoculums with 20% less NPK had statistically better role than full NPK without inoculation. AB-DTPA extractible P and mineral N were progressively increased with incubation periods and exhibited significant differences between inoculated and uninoculated treatments during all incubation intervals for NP except at day 7 for N. Peas inoculum showed maximum mean net NP availability of 131.5 and 3.48 mg kg⁻¹ over 56 d of incubation, respectively. Significantly higher cumulative CO₂ of 1429 mg kg⁻¹ with a net increase of 866 mg kg⁻¹ was recorded for pea’s inoculums during 12 d of incubation interval. It is concluded that peas rhizobium could be used as a plant-growth-promoting rhizobacteria for wheat and other cereal crops.

    Abstract To determine the genotypic distribution of HCV, frequency of risk factors involved in its transmission, and correlation of genotype with viral load in Mardan population which is the second largest city of Khyber Pakhtunkhwa (KPK), Pakistan. Blood samples of 1140 were collected from different regions of Mardan and major proportion of recruited patients were internally displaced people (IDPs), refugees, and slum dwellers. Complete patient's history was analyzed to assess the possible risks involved in HCV transmission. Viral genotype was determined by PCR (polymerase chain reaction) whereas, HCV RNA was measured by qRT-PCR. Data was analyzed using SPSS statistical software. Our results indicate 3a as the most abundant subtype in Mardan population followed by 3b, 2a, 2b, 4a, untypeable, mixed, 1a, and 1b. In contrast to previous findings, genotype 1 was the least prevalent genotype and the overall prevalence of HCV in Mardan population was significantly higher in females (n = 687, 60.2%) than males (n = 453, 39.7%). Significant difference between-genotypes and gender was observed in genotype 1 (p < .034) and genotype 3 (p < .004). The mean age was 44 (SD ± 9.51). The most frequently found mixed genotype was 3a + 1b and mixed genotype was more prevalent in males. The proportion of middle-aged people (41-49 years) was higher whereas, older and younger people were least infected with HCV. This is the first study that showed substantial correlation of genotype 3 with low and intermediate viral load in Mardan population. Moreover, high and extremely high viral load was associated with other genotypes. Our findings showed that most of the patients who experienced high and extremely high viremia in their blood were males and belonged to Takhat Bhai and Mardaan regions. There were significant difference in the prevalence of HCV genotype 3a (p = .001) and genotype 3b (p = .005) in different regions of Mardan. Pre-treatment viral load is significantly high (p 0.001) in tehsil Mardan patients infected with HCV genotype 3 as compared to other genotypes. Unsafe medical practices such as medical and dental surgeries, intravenous drug use, and blood transfusions were the main risk factors for HCV transmission in Mardan, KPK Pakistan. This study gives clear insights into the epidemiological status of HCV in Mardan population. Genotype 3 is correlated with low and intermediate viral load whereas high viral loads were revealed among patients infected with genotypes other than genotype 3. In the absence of better data and robust epidemiological information, this detailed analysis of HCV genotypes with special reference to risk factors, pretreatment viral load, gender, and age will provide the baseline data for development of optimal HCV eradication and preventive strategies.

    Abstract Renal artery stenosis (RAS) due to atherosclerosis continues to be a major cause of secondary hypertension. It can also lead to renal dysfunction due to ischemic nephropathy. While major clinical trials have emphasized that medical management should be preferred over angioplasty and stenting for the treatment of renal artery stenosis, clinical scenarios continue to raise doubts about the optimal management strategy. Herein, we present two cases that were admitted with hypertensive emergency and renal function deterioration. Medical therapy failed to control the blood pressure and in one patient, renal failure progressed to a point where renal replacement therapy was required. Both patients underwent angioplasty (for >90% stenosis) and stent insertion with successful resolution of stenosis by interventional radiology. Postoperatively, blood pressure gradually decreased with improvement in serum creatinine. Dialysis therapy was discontinued. At 4- and 8-month follow-up, both patients continue to do well with blood pressure readings in the 132-145/70-90 mmHg range. This article highlights the importance of percutaneous interventions in the management of atherosclerotic RAS and calls for heightened awareness and careful identification of candidates who would benefit from angioplasty and stent insertion.
