In this study, the Scheibel column with the regular packing structure was investigated in the extraction process of lanthanum and cerium ions. Mass transfer coefficients identified the column performance in the transport stage of La(III) and Ce(III) from the aqueous phase to the organic phase. The variations in operating conditions were investigated to optimize the extraction of ions. The backflow model (BFM), axial dispersion model (ADM), and forward mixing model (FMM) were investigated to evaluate the mass transfer performance. The result showed that the description of the volumetric overall mass transfer coefficient with forward mixing model is more significant than two other models. The medium of average absolute relative error obtained by the FMM model is ~4.45% and ~18.40% (lanthanum extraction) and ~10.75% and ~14.99% (cerium extraction) for continuous and dispersed phase, respectively. It indicated that the applied model has a remarkable accuracy for description of mass transfer performance

Plasma transfusion should never be used as child's play as the dire consequences of the plasma transfusion exercise can trigger a re-virulence of VZV at any point of time with failing immunocompetence of the body of a plasma transfusion recipient and catastrophic impacts of any negligent blood transfusion with and without the knowledge of the plasma transfusion recipient through willful ignorance perhaps or failing memory.

Aims: Non-small-cell lung cancer (NSCLC) is the most common clinical lung cancer. Polymorphonuclear-myeloid derived suppressor cells (PMN-MDSCs), which are the major population of MDSCs, are involved in NSCLC progression. Recently, it was found that lectin-type oxidized LDL receptor 1 (LOX-1) could identify humsn PMN-MDSCs. However, the role of CD15+LOX-1+ PMN-MDSCs in NSCLC early diagnosis has not been revealed. Here, we tried to confirm the application of the newly-identified CD15+LOX-1+ PMN-MDSCs in the early diagnosis of NSCLC. Methods: Flow cytometry (FCM) was used to detect the proportion of CD15+LOX-1+ PMN-MDSCs in the peripheral blood (PB) of healthy controls (HC) and NSCLC patients. The correlation of CD15+LOX-1+ PMN-MDSC frequency with levels of cytokeratin 19-fragments (CYFRA21-1), carcinoembryonic antigen (CEA), and carbohydrate antigen 125 (CA125) was analyzed. Receiver operating characteristic (ROC) curve was used to estimate the diagnostic efficacy of CD15+LOX-1+ PMN-MDSCs for NSCLC. Additionally, the association of CD15+LOX-1+ PMN-MDSC frequency with NSCLC prognosis/recurrence after surgery was explored. Results: The proportion of CD15+LOX-1+ PMN-MDSCs increased in PB of NSCLC patients. CD15+LOX-1+ PMN-MDSC proportion was positively correlated with levels of CEA and CYFRA21-1. The area under the ROC curve (AUC) of PMN-MDSC percentage was higher than CYFRA21-1, CEA and CA125. The proportion of CD15+LOX-1+ PMN-MDSCs decreased in patients after surgery. The frequency of CD15+LOX-1+ PMN-MDSCs was lower in NSCLC patients without recurrence compared to those with recurrence after surgery. Conclusions: Circulating CD15+LOX-1+ PMN-MDSCs are a potential diagnostic marker for NSCLC, and are associated with NSCLC prognosis and recurrence after surgery.

Objectives The aim of the present study was to investigate the effect of treatment on IL-1, IL-6, IL-8 and neopterin levels in patients with non-muscle invasive bladder cancer (NMIBC). Methods Thirty patients with NMIBC and 30 age-matched controls were included in the study. Preoperative, postoperative first control (at two weeks after second transurethral resection of bladder tumor (TURBT)) and second control (at the end of intravesical immunotherapy) blood samples were analyzed by ELISA to determine IL-1, IL-6, IL-8 and neopterin levels. The mean cytokine levels of the patients were statistically compared as well as comparing the patients’ and controls’ levels. Results There were no statistically significant differences between the mean IL-1, IL-6, IL-8 and neopterin levels of the patient and control group before initial TURBT. In the patient group, there were no statistically significant differences in the IL-6 and IL-8 levels after both TURBT and intravesical BCG therapy. The mean of preoperative IL-1 and neopterin levels significantly decrease after TURBT (p<0.05=). However this reduction do not continue after intravesical BCG instillations. Conclusions The finding of this study showed that the IL-1, IL-6, IL-8 and neopterin levels of the patients with NMIBC were similar to the levels of healthy controls. The IL-1 and neopterin levels significantly decreased after TURBT. But this reductions did not continue after intravesical BCG instillation. These findings demonstrate that IL-1 and neopterin levels decrease after TURBT due to the reduction of tumor weight or tumor removal.

Aim Extracorporeal shockwave therapy (ESWT) is known as one of the most effective treatment methods in plantar fasciitis (PF). Low-dye taping, which is the most preferred method of banding treatments, provides an analgesic effect by correcting biomechanics. It was aimed to compare the efficacy of adjuvant low-dye kinesio-taping (KT), sham-taping, or extracorporeal shockwave therapy (ESWT) alone in plantar fasciitis (PF). Methods In this double-blind, sham-controlled study, forty-five patients with PF were randomized to 3-group (Group 1: ESWT plus low-dye KT, n=15; Group 2: ESWT plus Sham-taping, n=15; and Group 3: ESWT only, n=15) five-session ESWT were administrated. KT was performed and changed every 1-week for the ESWT sessions in Groups 1 and 2. The main outcome measures were the visual analog scale (VAS) change, the heel tenderness index (HTI), foot function index (FFI). The patients were evaluated at the beginning and end of the treatment and the 4-week follow-up. Results The demographic characteristics and baseline outcomes between groups were similar (p>0.05). VAS and HTI changes were observed in all three groups, there was no difference between groups. Repeated-measures ANOVA showed a significant interaction between the time and the groups in FFI-total (F3.919= 2.607; p=.043). At the 4-week follow-up, when Groups 1 and 2 were evaluated, the lower FFI-total, FFI-disability, and FFI-activity limitation were statistically significant in Group 1 (p=0.027; p=0.026; p=0.029, respectively). When Group 1 and 3 were compared, the decrease in FFI-pain and FFI-activity limitation were significant in Group 1 (p=0.042; p=0.035, respectively). Conclusions Low-dye KT, in addition to ESWT, is more effective than sham-taping and ESWT in pain relief and foot function improvement due to PF at a 4-week follow-up.

Background/Aim: There is insufficient data on physiological and psychological alterations that may occur among health-care workers wearing various face masks during novel coronavirus-2019 (COVID-19) pandemic. In this study, we aimed to investigate the physiological effects of various types of face masking and associated discomfort among health-care workers. Methods: This prospective study included 33 healthy health-care workers. Each participant was asked to wear a single surgical mask, double mask, N95 type mask, and surgical mask on N95 type mask for an uninterrupted period of 2 hours. Oxygen saturation, heart pulse, blood pressure, respiratory rate, and step counts were recorded at baseline and every 30 min of 2 hours with a total of five times for each mask type. Self-assessment of fatigue, exhaustion, and headache were also graded. Intra- and inter-group analyses were performed. Results: There was no significant difference in the oxygen saturation, pulse and respiratory rates among the participants including intra- and inter-groups (p>0.05) Although no significant difference was seen in diastolic blood pressure, systolic blood pressures gradually and significantly increased with a double surgical mask (p<0.05). Headache and exhaustion scores increased gradually and significantly over time at every measurement time-point with every mask type (p<0.05) Fatigue scores also increased in intra-group comparison of mask types without any difference in-between. Conclusion: Our study results show that, during 2 hours of period, face mask types affect only subjective parameters such as headache, exhaustion, and fatigue without any change in the objective parameters such as oxygen saturation, and pulse and respiratory rates among health-care workers.

Introduction: This study aims to investigate the outcomes and complication rates of patients undergoing retrograde intrarenal surgery (RIRS) at the live surgery events organized as boutique course series. Materials and Methods: Eight RIRS courses were organized between November 2017 and February 2020. Data of 24 patients who were operated in the live surgery events (as LSE group) for renal stone were matched with the data of 24 substitute patients (as control group) who underwent regular RIRS on the same period at the same centers.. Results: Stone free status of groups was similar (88% in LSE and 79% in the control group; p=1). There was no significant difference in terms of complication and need for additional procedure rates, operation and fluoroscopy and hospitality times between the two groups (p=1, p=1, p=0.12, p=0.58 and p=0.94, respectively). Fifty-four % (13/24) of LSE operations were performed by guest surgeons. No statistically significant difference was found between the patients who operated by host and guest surgeons. However, the operation times of the operations performed by guest surgeons were longer than those performed by the host surgeons (96.5±28 and 66.5±30 minute, respectively, p=0.07). Conclusion: Our study is the first report on this area. RIRS live surgery can be performed with low complication and high stone-free rates without jeopardizing patient safety. If the surgeon is not familiar with the operating room set-up or staffs, the live surgery must performed by the host surgeon to avoid extended operating time.

Purpose: To investigate the prediction values of the preoperative NLR, LMR, PLR, MPV, RDW for recurrence and progression of patients with non-muscle invasive bladder cancer (NMIBC). Methods: In this prospective study, 94 consecutive patients, newly diagnosed with NMIBC between July 2017 - August 2018 were included. The blood samples were collected from patients before transurethral resection of bladder tumor (TURB) and NLR, LMR, PLR, RDW, MPV values were calculated. The effect of these preoperative inflammatory parameters and other clinicopathological parameters on recurrence and progression rates were evaluated. Kaplan-Meier and multivariate Cox regression analyses were performed to identify significant prognostic variables. Results: The mean follow-up was 11 ± 6.4 months. Recurrence was observed in 35.1% and progression was detected in 7.4% of the patients. Neutrophil-lymphocyte ratio was statistically significantly associated with both recurrence (p = 0.01) and progression (p = 0.035) whereas lymphocyte-monocyte ratio was only associated with recurrence (p = 0.038). In the survival analyses, the relationship between recurrence and LMR was confirmed in both univariate (p = 0.021) and multivariate (p = 0.022) analyses. The relationship between NLR and recurrence was confirmed in univariate analysis (p = 0.019), however in multivariate analysis was found to be statistically insignificant (p = 0.051). Conclusions: Lymphocyte-monocyte ratio might be an easy obtainable, non-invasive and cost-effective method for predicting recurrence of disease in patients with non-muscle invasive bladder cancer.

A non-isothermal pressure-balanced bubble-growth (PBB) model has been proposed based on mass, momentum and energy conservation, which additionally considered the decrease in the internal energy of gas due to the work done by gas expansion in bubble. The model could accurately predict the bubble size and expansion ratio for the melt foaming of four polymers for a wide range of cell densities from 1.5×1013 to 1.9×1015 cells/m3. Furthermore, the simulation results indicate that the bubble shell resisted bubble growth and consumed significant energy, preventing the growth of some small nucleations. During the melt foaming process, the energy cost of the linear polymer had a long-term effect, which reduced the bubble size, while that of the long-chain branched polymer had a short-term effect, thereby increasing the expansion ratio. Finally, we defined the gas efficiency of the foaming agent to evaluate the economic feasibility of the foaming agent in a foaming process.

The asymmetric sulfoxidation catalyzed by soybean pod peroxidase (SPP) in water-in-oil microemulsions were carried out with the yield of 91.56% and e.e of 96.08% at the activity of SPP of 3200 U ml-1 and 50℃ for 5 h. The mechanism with a two-electron reduction of SPP-I is accompanied with a single-electron transfer to SPP-I and nonenzymatic reactions, indicating that three concomitant sub-mechanisms contribute to the asymmetric oxidation involving five enzymatic and two nonenzymatic reactions, which can represent the asymmetric sulfoxidation of organic sulfides to form enantiopure sulfoxides. With 5.44% of the average relative deviation, a kinetic model fitting experimental data was developed. The enzymatic reactions may follow ping-pong mechanism with substrate inhibition of H2O2 and product inhibition of esomeprazole, while nonenzymatic reactions, a power law. Those results indicate that SPP with a lower cost and higher thermal stability may be used as an effective substitute for Horseradish Peroxidase.

Machine Learning (ML) algorithms can be combined with the modular automation protocol (MTP) and recognize the flooding behavior of laboratory fluids separation columns. Hence, artificial intelligence (AI) tools with deep learning (DL) offer a high potential for the process industry and allow to capture operating states that are otherwise difficult to detect or model. However, the advanced methods are only hesitantly applied in practice. This article provides an overview on how artificial intelligence-based algorithms can be implemented in existing laboratory plants. Process sensor data as well as image data are used to model the flooding behavior of distillation and extraction columns and the system is adapted to the existing modular automation standard of the Module Type Package (MTP).

Objectives: In this study, we designed a new technique for open septal reduction using a polydioxanone (PDS) plate and compared it with closed reduction. Design, Setting, Participants: This study included nineteen consecutive patients with nasoseptal fracture: ten receiving open reduction with a PDS plate (PDS group) and nine undergoing closed reduction (CR group). Open septal reduction was performed after closed reduction for nasal bone fracture. A mucoperichondrial flap was unilaterally elevated, and the deviated septal cartilage was reduced. The PDS plate was inserted horizontally above the vomerine suture. Surgical outcome was analyzed with three-dimensional volumetry and with a quality-of-life scale for nasal obstruction (NOSE scale). Results: Complications included one case of septal perforation in the CR group and one case of PDS exposure and septal hematoma in the PDS group. In the 3D volumetric analysis of the PDS group, the median value of the nasal cavity change significantly differed between 1.14 mL (interquartile range; 0.46 to 2.4) at the preoperative CT scan and 0.33 mL (interquartile range; -0.22 to 1.29) at the postoperative CT scan (**p = 0.0039). The NOSE scale revealed significant improvement in nasal obstruction postsurgically (median value, 42.5 to 7.5; *p = 0.0139) in the PDS group. Conclusion: PDS plates potentially present a new concept of open septal reduction in terms of septal reinforcement compared with the subtractive approach of open septal reduction.

Objective: Novel Coronavirus disease is a new infectious agent of the respiratory tract characterized by a severe acute respiratory syndrome. For this disease, there are limited data with regard to the clinical characteristics of the patients and prognostic factors. Study Design: Retrospective Cohort Setting: Secondary Referral Center Methods: We collected data from 213 patients who were hospitalized into COVID-19 isolation with positive PCR test results. We recorded various patient values, including blood test results. We also noted age, gender, additional diseases, duration of discharge, whether they live or die, whether they smoke, and their radiological staging. Results: In CT imaging with a staging of maximum 4 points and minimum 0 points, the mean value resulted in 1.95. The average radiological stage of the dead patients group was reported as 2.56. There was a correlation between the radiological predictor and the outcome status (p-value: 0.002). The number of smokers was 14 (6.5%). Of the 26 patients who died, 3 were smokers and 23 were non-smokers. Conclusion: 14 of the patients in the study were smokers (6.5%). One in four people in Turkey is a smoker, while in COVID-19 isolation service only a 6.5% rate of smoking was observed. That supports the theory that smoking hasn’t negative impact on COVID-19 development. The average radiological stage was reported as 2.56 in the dead patients’s group. There was a correlation between the radiological predictor and the outcome status (p-value: 0.002). It seems that an elevated radiological stage is a predictor of death. Keywords: Covid-19, SARS-CoV-2, smoking, computed tomography, predictor factors. Key points: to learn relations between smoking and covid-19, effect of Ct stages on the disease severity, effect of blood analysis on Covid-19, the parameters in deaths of Covid-19, ratio of smoking in Covid-19 inpatients

OBJECTIVE. For many years, functional tricuspid regurgitation (FTR) was considered negligible after treatment of left-sided heart valve surgery. The aim of the present network meta-analysis is to summarize the results of four approaches in order to establish the possible gold standard. METHODS A systematic search was performed to identify all publications reporting the outcomes of four approach for FTR, not tricuspid annuloplasty (no TA), suture annuloplasty (SA), flexible (FRA), rigid rings (RRA). All studies reporting at least one the four endpoints (early and late mortality, early and late moderate or more TFR) were included in a Bayesian network meta-analysis. RESULTS There were 31 included studies with 9,663 patients. Aggregate early mortality was 5.3% no TA, 7.2% SA, 6.6% FRA and 6.4% RRA; Early TR moderate-or-more was 9.6%, 4.8%, 4.6% and 3.8%; Late mortality was 22.5%, 18.2%, 11.9% and 11.9%; Late TR moderate-or-more was 27.9%, 18.3%, 14.3% and 6.4%. Rigid or semirigid ring annuloplasty was the most effective approach for decreasing the risk of late moderate or more FTR (–85% vs. no TA; –64% vs. SA; –32% vs. FRA). Concerning late mortality, no significant differences were found among different surgical approaches, however, flexible or rigid rings reduced significantly the risk of late mortality (78% and 47%, respectively) compared with not performing TA mortality. No differences were found for early outcomes. CONCLUSIONS. Ring annuloplasty seems to offer better late outcomes compare to either suture annuloplasty or not performing TA. In particular rigid or semirigid rings provides more stable FTR across time.

Background and aim of the study: Sutureless and rapid-deployment bioprostheses have been introduced as alternative to traditional prosthetic valves to reduce cardiopulmonary and aortic cross-clamp times during aortic valve replacement.These devices have been employed also in extremely demanding surgical settings as underlined in the present review. Methods: A search on PubMed and Medline databases aimed to identify, from the English literature, the reported cases where both sutureless and rapid- deployment prostheses were employed in challenging surgical situations, usually complex reoperations sometimes even performed as a bail out procedures. Results: We have identified 25 patients in whom a sutureless or a rapid-deployment prosthesis were used in complex redo procedures. In 17 patients a failing stentless bioprosthesis was replaced with a sutureless (n=14) or a rapid deployment valve (n=3). Bioprostheses implanted at first operation were mainly Freestyle (n=11) or Prima Plus (n=3) aortic roots, while Perceval (n=13) and Intuity (n=3) were those most frequently employed at reoperation. A failing homograft was replaced in 6 patients using a Perceval (n=5) or an Intuity (n=1) bioprosthesis while a Perceval was used to replace the aortic valve in 2 patients to treat failure of a valve-sparing procedure. All patients survived reoperation and are reported alive 3 months to 4 years postoperatively. Conclusions: Sutureless and rapid-deployment bioprostheses have proved effective in replacing degenerated stentless bioprostheses and homografts in challenging redo procedures. In these setting, they should be considered as a valid alternative not only to traditional prostheses but also in selected cases to transcatheter valve-in-valve solutions.

Coronary artery aneurysm (CAA) has been increasingly reported in recent years. The symptoms are related to myocardial ischemia, such as angina pectoris, myocardial infarction, sudden death and congestive heart failure. This report describes a case of a giant CAA with calcification and stenosis involving two coronary arteries, and the patient underwent a complete arterialized coronary artery bypass graft successfully. In this report, all cases related to CAA with calcification and stenosis are summarized. According to the data, the following conclusions can be drawn: CAA seem to be more common in men; Kawasaki disease is likely to be a causative factor in some patients with asymptomatic CAA involving calcification and stenosis; CABG is a feasible treatment option for CAA with calcification and stenosis.

In this paper, we consider the generalized approximate boundary synchronization for a coupled system of wave equations with Dirichlet boundary controls. We analyse the relationship between the generalized approximate boundary synchronization and the generalized exact boundary synchronization, give a sufficient condition to realize the generalized approximate boundary synchronization and a necessary condition in terms of Kalman's matrix, and show the meaning of the number of total controls. Besides, by the generalized synchronization decomposition, we define the generalized approximately synchronizable state, and obtain its properties and a sufficient condition for it to be independent of applied boundary controls.

Background: Erythrocytes and platelets have been demonstrated to play a critical role in inflammatory processes. However, little is known about the diagnostic value of these indices in RA patients. The aim of this study was to evaluate the clinical significance of blood counts-related parameters such as counts of red blood cells (RBCs) and platelets (PLTs), hemoglobin (Hb), red blood cells-platelet ratio (RPR) and hemoglobin-platelet ratio (HPR) in rheumatoid arthritis (RA) and their association with disease activity. Methods: Clinical and laboratory data from 178 RA patients and 164 healthy controls were collected and analyzed. RA patients were divided into inactive group and active group according to disease activity score in 28 joints based on C-reactive protein (DAS28-CRP). The relationship between blood RBC, Hb, PLT, RPR and HPR and DAS28-CRP was detected by Spearman correlation method. Receiver operating characteristic (ROC) curve was used to assess the diagnostic value of these parameters. The predictive role of these indices for RA disease activity was evaluated by logistical regression analysis. Results: Active RA patients exhibited lower levels of blood RBC counts, Hb, HCT, RPR and HPR but significantly higher level of PLT counts compared with those in inactive groups (P < 0.01). Spearman analysis showed that blood RBC counts, HCT, RPR and HPR were negatively but PLT counts were positively related with DAS28-CRP (P < 0.001) in RA. ROC curve analysis revealed that the AUC of RBC and Hb was higher than that of ESR, RF and CCP for distinguishing active RA from inactive group. Logistical regression analyses showed that PLT is an independent predictor for RA disease activity. Conclusion: Blood RBC counts, Hb, RPR and HPR were negatively but PLT counts were positively related with RA disease activity. Blood PLT may act as a novel inflammatory factor for predicting disease activity in RA.

Organisms have evolved effective and distinct adaptive strategies to survive. Stipa grandis is one of the widespread dominant species on the typical steppe of the Inner Mongolian Plateau, and is regarded as a suitable species for studying the effects of grazing in this region. Although phenotypic (morphological and physiological) variations in S. grandis in response to long-term grazing have been identified, the molecular mechanisms underlying adaptations and plastic responses remain largely unknown. Accordingly, we performed a transcriptomic analysis to investigate changes in gene expression of S. grandis under four different grazing intensities. A total of 2,357 differentially expressed genes (DEGs) were identified among the tested grazing intensities, suggesting long-term grazing resulted in gene expression plasticity that affected diverse biological processes and metabolic pathways in S. grandis. DEGs were identified that indicated modulation of Calvin–Benson cycle and photorespiration metabolic pathways. The key gene´expression profiles encoding various proteins (e.g., Ribulose-1,5-bisphosphate carboxylase/oxygenase, fructose-1,6-bisphosphate aldolase, glycolate oxidase etc.) involved in these pathways suggest that they may synergistically respond to grazing to increase the resilience and stress tolerance of S. grandis. Our findings provide scientific clues for improving grassland use and protection, and identify important questions to address in future transcriptome studies.

In eukaryotes, alternative splicing (AS) is a crucial regulatory mechanism that modulates mRNA diversity and stability. The contribution of AS to stress are known in many species related to stress. But the post-transcriptional mechanism in poplar under cold stress is still unclear. Recent studies have utilized the advantages of Single Molecular Real Time (SMRT) sequencing technology from Pacific Bioscience (PacBio) to identify full-length transcripts. We, therefore, used a combination of single-molecule long-read sequencing and Illumina RNA sequencing (RNA-Seq) for a global analysis of AS in two poplar species (Populus trichocarpa and P. ussuriensis) under cold stress. We further identified 1261 AS events in P. trichocarpa and 2101 in P. ussuriensis, among which intron retention, with a frequency of more than 30%, was the most prominent type under cold stress. RNA-Seq data analysis and annotation revealed the importance of calcium, abscisic acid, and reactive oxygen species signaling in cold stress response. Besides, the low temperature rapidly induced multiple splicing factors, transcription factors, and differentially expressed genes through AS. In P. ussuriensis, there was a rapid occurrence of AS events. This study provides new insight into the complexity and regulation of AS during cold stress response in two poplar species.

Cardiac arrythmia is a major complication of COVID-19. This occurs often in patients with severe COVID-19 with pre-existing cardiovascular diseases. We report an unusual case of paroxysmal atrial fibrillation in an adult male with low cardiovascular risk factor who presented with a moderate form of COVID-19.

Pulmonary Tuberculosis (PTB) and Novel Coronavirus disease 2019 (COVID 19) primarily affect the lungs. Both diseases present with fever, cough, and shortness of breath and possess thrombotic potential as well. Therefore in COVID 19 pandemic, PTB must be taken into consideration for suspected cases in order to avoid fatal consequences.
