Abstract
This study evaluated the impact of conventional practices (fertilizer alone) and diverse farming approaches (such as green manuring, farmyard manure application, rice-residue incorporation, residue mulching, residue removal and residue burning) on soil attributes. A total of thirty-five farm sites were selected, with five sites (replications) for each farming approach system, which were used over the past three years in the study farms. Characterization of rice residues of all cultivars, green manure crop (sesbenia: Sesbania sesban) and decomposed farmyard manure samples showed differential behaviours for macronutrients and micronutrients. Continuous application of inorganic fertilizers significantly influenced soil attributes, especially electrical conductivity, nutrient contents, bacterial and fungal population and soil enzymatic attributes. The crop residue treatments favourably influenced the soil parameters over the control. Crop residue incorporation or burning significantly increased soil available potassium, microbial biomass, enzymatic activities and organic carbon when compared with applications of chemical fertilizer alone, while total nitrogen content was increased by residue incorporation. However, green manuring and farmyard manure applications showed inferior responses compared with residue management treatment. It is therefore recommended that bioresources should be managed properly to warrant improvements in soil properties, nutrient recycling and the sustainability for crop productivity, in order to achieve sustainable development goals for climate action.

Abstract
As part of the growing evolution in nanotechnology and thermal sciences, nanoparticles are considered as an alternative solution for the energy depletion due to their ultra-high thermal effectives. Nanofluids reflect inclusive and broad-spectrum significances in engineering, industrial and bio-engineering like power plants, energy source, air conditioning systems, surface coatings, evaporators, power consumptions, nano-medicine, cancer treatment, etc. The present study describes the bio-convective peristaltic flow of a third-grade nanofluid in a tapered asymmetric channel. Basic conservation laws of mass, momentum, energy, and concentration as well as the microorganism diffusion equation are utilized to model the problem. The simplified form of the modeled expressions is accounted with long wavelength assumptions. For solving the resulting coupled and nonlinear equations, a well-known numerical method implicit finite difference scheme has been utilized. The graphical results describe the velocity, temperature and concentration profiles, and the density of motile microorganisms at the nanoscale. Furthermore, microorganism concentration lines are analyzed.

Abstract
OBJECTIVES The aim of this study is to investigate the effect of two abundant dietary supplements, quercetin and vitamin C on some factors involved in metastasis and proliferation of prostate cancer, which are resistant to conventional chemotherapies in late stages. BACKGROUND Bone and brain are two common sites of metastases in prostate cancer, nevertheless the factors involved in their metastatic pathways are not well understood. METHODS The effect of quercetin (75µM) and vitamin C (100 µM) on CXCR4, CXCR7 chemokine receptors, α4, α5 and β1 integrins, ki-67 proliferation marker and Vascular endothelial growth factor, VEGF was evaluated using Quantitative Reverse Transcription PCR (RT-qPCR). RESULTS The effect of quercetin and vitamin C alone was different on PC3 and DU145 prostate cancer cell lines, but sequential combination reduced significantly the expression of CXCR and CXCR7 chemokine receptors, α4, α5 and β1 integrin subunits, VEGF and Ki-67 proliferation markers in PC3 and DU145 cell lines. CONCLUSION Our results indicated the beneficial effect of quercetin and vitamin C on prostate cancer cells with different metastatic sites and their differential response to the treatment which in turn may lead us to reach suitable therapeutic outcomes to combat cancer (Fig. 3, Ref. 36).

Abstract
AIM To evaluate whether portable chest radiography (CXR) scores are associated with coronavirus disease 2019 (COVID-19) status and various clinical outcomes. MATERIALS AND METHODS This retrospective study included 500 initial CXR from COVID-19-suspected patients. Each CXR was scored based on geographic extent and degree of opacity as indicators of disease severity. COVID-19 status and clinical outcomes including intensive care unit (ICU) admission, mechanical ventilation, mortality, length of hospitalisation, and duration on ventilator were collected. Multivariable logistic regression analysis was performed to evaluate the relationship between CXR scores and COVID-19 status, CXR scores and clinical outcomes, adjusted for code status, age, gender and co-morbidities. RESULTS The interclass correlation coefficients amongst raters were 0.94 and 0.90 for the extent score and opacity score, respectively. CXR scores were significantly (p < 0.01) associated with COVID-19 positivity (odd ratio [OR] = 1.49; 95% confidence interval [CI]: 1.27 - 1.75 for extent score and OR = 1.75; 95% CI: 1.42 - 2.15 for opacity score), ICU admission (OR = 1.19; 95% CI: 1.09 - 1.31 for extent score and OR = 1.26; 95% CI: 1.10 - 1.44 for opacity score), and invasive mechanical ventilation (OR = 1.22; 95% CI: 1.11 - 1.35 for geographic score and OR = 1.21; 95% CI: 1.05 - 1.38 for opacity score). CXR scores were not significantly different between survivors and non-survivors after adjusting for code status (p>0.05). CXR scores were not associated with length of hospitalisation or duration on ventilation (p>0.05). CONCLUSIONS Initial CXR scores have prognostic value and are associated with COVID-19 positivity, ICU admission, and mechanical ventilation.

Abstract
A critical step in effective care and treatment planning for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause for the coronavirus disease 2019 (COVID-19) pandemic, is the assessment of the severity of disease progression. Chest x-rays (CXRs) are often used to assess SARS-CoV-2 severity, with two important assessment metrics being extent of lung involvement and degree of opacity. In this proof-of-concept study, we assess the feasibility of computer-aided scoring of CXRs of SARS-CoV-2 lung disease severity using a deep learning system. Data consisted of 396 CXRs from SARS-CoV-2 positive patient cases. Geographic extent and opacity extent were scored by two board-certified expert chest radiologists (with 20+ years of experience) and a 2nd-year radiology resident. The deep neural networks used in this study, which we name COVID-Net S, are based on a COVID-Net network architecture. 100 versions of the network were independently learned (50 to perform geographic extent scoring and 50 to perform opacity extent scoring) using random subsets of CXRs from the study, and we evaluated the networks using stratified Monte Carlo cross-validation experiments. The COVID-Net S deep neural networks yielded R[Formula: see text] of [Formula: see text] and [Formula: see text] between predicted scores and radiologist scores for geographic extent and opacity extent, respectively, in stratified Monte Carlo cross-validation experiments. The best performing COVID-Net S networks achieved R[Formula: see text] of 0.739 and 0.741 between predicted scores and radiologist scores for geographic extent and opacity extent, respectively. The results are promising and suggest that the use of deep neural networks on CXRs could be an effective tool for computer-aided assessment of SARS-CoV-2 lung disease severity, although additional studies are needed before adoption for routine clinical use.

Abstract
Introduction/Objective The recent outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in Hubei province, China in December 2019 and has spread worldwide at an alarming rate. With millions of individuals infected and over two hundred thousand deaths, the necessity to develop fast and efficient diagnostic methods is of high importance. Diagnostic modalities rely on a combination of epidemiology, clinical presentation, laboratory examination, and appropriate imaging to diagnose and distinguish SARS-CoV-2 from other pulmonary infections. The purpose of this paper is to report on currently available diagnostic screening methods for patients infected with SARS-CoV-2 to guide frontline healthcare workers involved with COVID-19 patient care. Methods An electronic literature search was performed for peer-reviewed articles published from January 1, 2020, until April 26, 2020. Articles were then reviewed and included based on the applicability to the topic. Results The preferred diagnostic approach is reverse transcription of the virus’ RNA followed by PCR amplification (RT-PCR). This method recognizes the gene-specific primers to target various viral protein genes, such as the envelope protein gene or the nucleocapsid protein gene, which enables this test to be both sensitive and specific toward SARS-CoV-2. However, this method has been proven to be time-consuming taking hours-to-days for the results. In order to improve the speed and efficiency of diagnostics, newer rapid diagnostic serological tests are being developed for testing SARS-CoV-2, each with its own unique advantages and disadvantages. They could potentially be used as triage tests to rapidly identify patients who are very likely to have COVID-19 in combination with other accurate diagnostic methods. Conclusion Therefore, a combination of diagnostic testing used in a timely manner may be beneficial for the rapid and accurate detection of SARS-CoV-2. This was evident in cases where despite initial negative RT-PCR tests for various patients, who later demonstrate chest CT scans with various degrees of consolidation and ground-glass opacity. Thus establishing the need for radiology diagnosis to be complementary to RT-PCR for COVID-19 patients. Hopefully, the continuous development and use of rapid diagnostic tests and the implementation of public health measures will help control the spread of the disease.

Abstract
Inflammation is a sophisticated biological tissue response to both extrinsic and intrinsic stimuli. Although the pathological aspects of inflammation are well appreciated, there are still rooms for understanding the physiological functions of the inflammation. Recent studies have focused on mechanisms, context and the role of physiological inflammation. Besides, there have been progress in the comprehension of commensal microbiota, immunometabolism, cancer and intracellular signaling events' roles that impact on the regulation of inflammation. Despite the fact that inflammatory responses are vital through tissue damage, understanding the mechanisms to turn off the finished or unnecessary inflammation is crucial for restoring homeostasis. Inflammation seems to be a smart process that acts like two edges of a sword, meaning that it has both protective and deleterious consequences. Knowing both edges and the regulation processes will help the future understanding and therapy for various diseases.

Abstract
The present study was aimed to investigate oxidative stress, DNA damage, and histopatholog- ical alterations in hepatic tissues of splenectomized Wistar rats experimentally infected with Ba- besia bigemina. Rats were challenged with 5x106 infected erythrocytes. Babesia infection was con- firmed both with Giemsa's staining blood smears and nested-PCR amplified region of apical membrane antigen-1 (AMA-1) gene. Parasitemia reached approximately 10 % at day 5 post-in- fection. Livers of infected rats were enlarged and darker in color, became extremely brittle with marked congestion. Microscopic evaluation showed cytoplasmic clearing of hepatocytes and se- vere hydropic changes with significantly dilated sinusoids containing macrophages and also intra- sinosoidal parasitized erythrocytes. Severe infiltration of lymphoplasma cells was also present throughout the liver parenchyma. Furthermore, Kupffer cells were enlarged and, occasionally, containing Babesia-parasitized erythrocytes. The activity of Glutathione (GSH) and catalase (CAT), and total antioxidant capacity (TAC) were also significantly decreased (p ⟨ 0.05) after infection of rats with B. bigemina. B. bigemina infection also induced a significant increase (p ⟨ 0.05) in hepatic malondialdehyde (MDA) and nitric oxide-derived products (NOx) concentra- tions as well as amount of endogenous hepatocytes DNA damage. Hepatic damage was also re- flected through the measurement of lactic acid dehydrogenase (LDH) and protein carbonyl con- tent (PCO) in liver cells. These two indices of liver injury were also significantly elevated (p ⟨ 0.5) during B. bigemina infection. Evaluation of correlation between assayed variables in infected rats revealed that MDA levels were positively correlated with PCO, NOx, LDH and DNA damage in the infected group and negatively correlated with GSH, CAT and TAC. There was also an inverse relationship between the antioxidant enzymes activities of GSH, CAT and TAC with PCO, NOx and DNA damage in infected rats. However, NOx showed positive correlation with PCO and DNA damage in infected rats. On the basis of the above results it can be concluded that the Ba- besia infection increases oxidative stress markers, protein carbonyl content and DNA damage and decreases antioxidant enzymes activities in the liver. These results suggest that B. bigemina infec- tion could alter the liver histopathology and causes DNA damage following oxidative stress in hepatic tissue. Further studies are needed to precisely define how hepatic tissue damage takes place in B. bigemina infection.

Abstract
BACKGROUND Aerobic training (AT) decreases airway inflammation in asthma, but the underlying cellular and molecular mechanisms are not completely understood. Thus, this study evaluated the participation of SOCS-JAK-STAT signaling in the effects of AT on airway inflammation, remodeling and hyperresponsiveness in a model of allergic airway inflammation. METHODS C57Bl/6 mice were divided into Control (Co), Exercise (Ex), HDM (HDM), and HDM+Exercise (HDM+ Ex). Dermatophagoides pteronyssinus (100ug/mouse) were administered oro-tracheally on days 0, 7, 14, 21, 28, 35, 42 and 49. AT was performed in a treadmill during 4 weeks in moderate intensity, from day 24 until day 52. RESULTS AT inhibited HDM-induced total cells (p<0.001), eosinophils (p<0.01), neutrophils (p<0.01) and lymphocytes (p<0.01) in BAL, and eosinophils (p<0.01), neutrophils (p<0.01) and lymphocytes (p<0.01) in peribronchial space. AT also reduced BAL levels of IL-4 (p<0.001), IL-5 (p<0.001), IL-13 (p<0.001), CXCL1 (p<0.01), IL-17 (p<0.01), IL-23 (p<0.05), IL-33 (p<0.05), while increased IL- 10 (p<0.05). Airway collagen fibers (p<0.01), elastic fibers p<0.01) and mucin (p<0.01) were also reduced by AT. AT also inhibited HDM-induced airway hyperresponsiveness (AHR) to methacholine 6,25mg/ml (p<0.01), 12,5mg/mL (p<0.01), 25mg/mL (p<0.01) and 50mg/mL (p<0.01). Mechanistically, AT reduced the expression of STAT6 (p<0.05), STAT3 (p<0.001), STAT5 (p<0.01) and JAK2 (p<0.001), similarly by peribronchial leukocytes and by airway epithelial cells. SOCS1 expression (p<0.001) was upregulated in leukocytes and in epithelial cells, SOCS2 (p<0.01) was upregulated in leukocytes and SOCS3 down-regulated in leukocytes (p<0.05) and in epithelial cells (p<0.001). CONCLUSIONS AT reduces asthma phenotype involving SOCSJAK- STAT signaling.

Abstract
Leptin is a 16-kDa peptide hormone secreted by adipose tissue that participates in the regulation of energy homeostasis. The aim of this study was to determine the effect of leptin injection on mRNA expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) and comparison of PPAR-γ mRNA expression in rat's adipose and liver tissue. Twenty adult male rats were divided into the following groups: Group 1asa control (n=10) that did not receive any treatment. Group 2as a treatment (n=10) that received leptin (30 µg ⁄ kg BW) intraperitoneally (ip) for two successive days. Blood samples were taken before and one day after second leptin injection for triglyceride (TG), Free Fatty Acid (FFA), HLD-cholesterol, and LDL-cholesterol measurement. Total RNA was extractedfrom the adipose tissue and liver tissues of rats. Adipose and liver tissue cells' cDNA was synthesized to characterize the expression of PPAR-γ. Gene expression of PPAR-γ mRNA was tested by RT- PCR technique. Results show leptin decreases expression of PPAR-γ on rat. Low levels of PPAR-γ mRNA were detected in adipose and liver tissues of treatment rats in comparison to control group. In treatment group, the level of PPAR-γ mRNA in liver tissue was very lower than the adipose tissue. The levels of HDL and FFA in treatment rats were increased whereas serum levels TG, VLDL and LDL were not changed. It is concluded that leptin signal with suppressing of PPAR-γ mRNA expression in rat's adipose and liver tissues can result in lipolysis instead of lipogenesis.

Abstract
Context Thyroid cancer is the most common endocrine malignancy. Within various subtypes of thyroid neoplasms, those with follicular growth pattern usually make diagnostic problems. Objective To examine ck19 expression as a diagnostic marker in thyroid neoplasms with follicular growth pattern. Design In this cross sectional study, 86 patients were enrolled. Subjects and Methods Totally 22 follicular adenoma (FA), 18 well differentiated tumors with undetermined malignant potential (WT-UMP) and 46 follicular variants of papillary thyroid carcinoma (FV-PTC) were enrolled and examined for Ck19 expression by immunohistochemistry staining. Membranous/cytoplasmic staining patterns were considered as positive. Specimens without staining were considered as 0, < 5% positively stained cells as 1+, 5%-25% as 2+, 25%-75% as 3+ and >75% as 4+. Result CK19 was negative in most cases of FA while positive in most WDT-UMP and FV-PTCs, p<0.001. Additionally, most cases with 2+ and 3+ staining patterns were FV-PTC (75% and 81%, respectively, p<0.001) and none of FAs showed 3+ positivity (p<0.001). Additionally, most of strongly positive results in patients > 45 y/o were PTC (p<0.001). Conclusion Ck19 is a useful marker in differentiating FA from FV-PTC. We found diffuse and strong (3+) staining pattern in FV-PTC but none of FAs were so. We concluded that diffuse and strong staining for ck19 in a thyroid lesion with follicular pattern of growth, especially in a patient older than 45 y/o should raise the possibility of malignancy.
