RESUMEN

Pakistan is included in top 50 countries which are estimated to face serious agriculture and food deficiency related challenges due to the worldwide pandemic coronavirus 2019 (COVID-19). The aim of this study was to evaluate the effects of COVID-19 on food supply chain and agriculture in Punjab, Pakistan, by using space-time scan statistic (STSS). A survey was conducted at 720 points in different districts of the province. The STSS detected "active" and emerging clusters that are current at the end of our study area-particularly, 17 clusters were formed while adding the updated case data. Software ArcGIS 10.3 was used to find relative risk (RR) values; the maximum RR value was found to be 42.19 and maximum observed cases 53,265 during June 15-July 1, 2020. It was not always necessary that if the number of active cases in Punjab increased, there should be higher relative risk for more number of districts and vice versa. Due to the highest number of cases of COVID-19 and RR values during July, mostly farmers faced many difficulties during the cultivation of cotton and rice. Mostly farmers (72%) observed increase in prices of inputs (fertilizers and pesticides) during lockdown. If the supply chain of agriculture related inputs is disturbed, farmers may find it quite difficult to access markets, which could result in a decline in production and sales of crops and livestock in study area. It is suggested that to protect the food security and to decrease the effect of the lockdown, Punjab government needs to review food policy and analyse how market forces will respond to the imbalanced storage facilities and capacity, supply and demand and price control of products. The findings of this study can also help policy-makers to formulate an effective food security and agriculture adaptation strategy.

RESUMEN

BACKGROUND: Although androgen in gender disparity of COVID-19 has been implied, no direct link has been provided. RESEARCH DESIGN AND METHODS: Here, we applied AlphaFold multimer, network and single cells database analyses to highlight specificity of Androgen receptor (AR) against spike receptor binding protein (RBD) of SARS-CoV-2. RESULTS: LXXL motifs in spike RBD are essential for AR binding. RBD LXXA mutation complex with the AR depicting slightly reduced binding energy, as LXXLL motif usually mediates nuclear receptor binding to coregulators. Moreover, AR preferred to bind a LYRL motif in specificity and interaction interface, and showed reduced affinity against Omicron compared to other variants (alpha, beta, gamma, and delta). Importantly, RBD LYRL motif is a conserved antigenic epitope (9 residues) for T-cell response. Network analysis of AR-related genes against COVID-19 database showed T-cell signaling regulation, and CD8+ T-cell spatial location in AR+ single cells, which is consistent with the AR binding motif LYRL in epitope function. CONCLUSIONS: We provided the potent mechanisms of AR binding to RBD linking to immune response and vaccination shift. AR could be an anti-infective therapy target for anti-Omicron new lineages.

RESUMEN

Background Lumbar radiculopathy is an extensively common complaint reported by patients of low back pain (LBP), resulting in several impairments. A comparatively novel technique, non-surgical spinal decompression (NSD), is introduced, which uses a sensitive computerized feedback mechanism and decompresses the spinal nerve roots through segmental distraction. The objective of this study was to determine the effects of NSD therapy in addition to routine physical therapy on pain, lumbar range of motion (ROM), functional disability, back muscle endurance (BME), and quality of life (QOL) in patients with lumbar radiculopathy. Methods A total of sixty patients with lumbar radiculopathy were randomly allocated into two groups, an experimental (n = 30) and a control (n = 30) group, through a computer-generated random number table. Baseline values were recorded before providing any treatment by using a visual analogue scale (VAS), Urdu version of Oswestry disability index (ODI-U), modified-modified Schober’s test (MMST), prone isometric chest raise test, and Short Form 36-Item Survey (SF-36) for measuring the pain at rest, functional disability, lumbar ROM, BME, and QOL, respectively. All patients received twelve treatment sessions over 4 weeks, and then all outcome measures were again recorded. Results By using the ANCOVA test, a statistically significant (p < 0.05) between-group improvement was observed in VAS, ODI-U, BME, lumbar ROM, role physical (RP), and bodily pain (BP) domains of SF-36, which was in favour of NSD therapy group. The between-group difference was 1.07 ± 0.32 cm (p < .001) for VAS, 5.65 ± 1.48 points (p < .001) for ODI-U, 13.93 ± 5.85 s (p = 0.002) for BME, 2.62 ± 0.27 cm (p < .001) for lumbar flexion, 0.96 ± 0.28 (p < .001) for lumbar extension, 5.77 ± 2.39 (p = 0.019) for RP and 6.33 ± 2.52 (p = 0.016) for BP domain of SF-36. For these outcomes, a medium to large effect size (d = 0.61–2.47, 95% CI: 0.09–3.14) was observed. Conclusion It was concluded that a combination of non-surgical spinal decompression therapy with routine physical therapy is more effective, statistically and clinically, than routine physical therapy alone in terms of improving pain, lumbar range of motion, back muscle endurance, functional disability, and physical role domain of quality of life, in patients with lumbar radiculopathy, following 4 weeks of treatment. Trial registration WHO Iranian registry of clinical trials (IRCT20190717044238N1) Dated: 23.12.2019.

RESUMEN

The COVID-19 pandemic has highlighted the need for innovative biosensing, diagnostic, and surveillance platforms. Here we report that glycosylated, polymer-stabilized, gold nanorods can bind the SARS-CoV-2 spike protein and show correlation to the presence of SARS-CoV-2 in primary COVID-19 clinical samples. Telechelic polymers were prepared by reversible addition-fragmentation chain-transfer polymerization, enabling the capture of 2,3-sialyllactose and immobilization onto gold nanorods. Control experiments with a panel of lectins and a galactosamine-terminated polymer confirmed the selective binding. The glycosylated rods were shown to give dose-dependent responses against recombinant truncated SARS-CoV-2 spike protein, and the responses were further correlated using primary patient swab samples. The essentiality of the anisotropic particles for reducing the background interference is demonstrated. This highlights the utility of polymer tethering of glycans for plasmonic biosensors of infection.

RESUMEN

The purpose of this study is to ascertain behavioral biases and preference of investors in their investment. In this study, open ended interviews from the investors were conducted at Pakistan Stock Exchange-Lahore to describe their preferences and behavioral aspect in investment. The findings from 10 open-ended interviews shows that the investors hold different preferences and beliefs regarding investment decisions. collectively, three themes emerged as common beliefs of investors from this study. Knowledge with risk appears more sensible than high risk high return. Secondly, investor does not hold any consistent behavioral pattern, but their behavior is influenced by circumstances. The concept of luck can be justified as irrational behavior only and only if the timing match with your investment. This study contributes in terms of qualitative assessment of individual behaviors and preferences using interviews.

RESUMEN

The novel coronavirus disease outbreak started in December, 2019 in Wuhan, China. On March 11, 2020, WHO declared COVID-19 outbreak as a pandemic due to uncontrolled situation. Pakistani government management against COVID-19 was excellent having 204.65 million population, all four provinces, two independent territories, and federal state took different initiative in pandamic situation c. that's why the situation was under control in Pakistan due to state respond urgently to halt the spread of disease. With rapid response and full support of the government of Pakistan, the situation was under control in all aspects of life, June 17, 2019, each district of Pakistan recorded at least one confirmed case of COVID-19 due to remarkable effort against pandemic. The state of Pakistan declare urgency and fastest action to control the situation, economic package, ventilator manufacturing, and diagnostic kits were manufactured locally. The DRAP Pakistan permitted to use different drugs against COVID-19 and purchased vaccines from China. Due to the planning and management of the Pakistani Government, the situation was under control as compared with neighborhood countries (China and India), in both countries COVID-19 waves was lethal.

RESUMEN

Variants of SARS-CoV-2 lineages including the most recently circulated Omicron, and previous pandemic B.1.351, B.1.1.7, which have been public concerns, contain a N501Y mutation located in the spike receptor binding domain. However, the potential interactions with host cells linking N501Y mutation to pathogenic relevance remain elusive. Recently, we and others report that kinases such as PI3K/AKT signaling are essential in SARS-CoV-2 entry. Here we analyzed the predicted potential kinases interacting with the mutation. Bioinformatics tools including structure-prediction based molecular docking analysis were applied. We found kinases such as EGFR might potentially act as new factors involving the N501Y mutation binding through possible phosphorylation at Y501 and enhanced affinity in certain variants. To our surprise, the Omicron receptor binding domain harboring N501Y mutation did not enhance binding to EGFR which might be due to the mutations of charged polar to uncharged polar side chains located on the interaction interfaces. Similarly, potent gains of phosphorylation in B.1.351 and B.1.1.7 by mutations were predicted and interaction networks were analyzed with enrichment of pathways. Given kinases might be elevated in cancer patients, the N501Y mutation containing lineages may be possibly much more infectious and additional care for cancer management might be taken into consideration by precision prevention, therapy or recovery.

RESUMEN

The COVID-19 pandemic, and future pandemics, require diagnostic tools to track disease spread and guide the isolation of (a)symptomatic individuals. Lateral-flow diagnostics (LFDs) are rapid and of lower cost than molecular (genetic) tests, with current LFDs using antibodies as their recognition units. Herein, we develop a prototype flow-through device (related, but distinct to LFDs), utilizing N-acetyl neuraminic acid-functionalized, polymer-coated, gold nanoparticles as the detection/capture unit for SARS-COV-2, by targeting the sialic acid-binding site of the spike protein. The prototype device can give rapid results, with higher viral loads being faster than lower viral loads. The prototype's effectiveness is demonstrated using spike protein, lentiviral models, and a panel of heat-inactivated primary patient nasal swabs. The device was also shown to retain detection capability toward recombinant spike proteins from several variants (mutants) of concern. This study provides the proof of principle that glyco-lateral-flow devices could be developed to be used in the tracking monitoring of infectious agents, to complement, or as alternatives to antibody-based systems.
