Introduction: Severe acute respiratory syndrome-related coronavirus (SARS-CoV-2) infection is characterised by a viral phase and a severe pro-inflammatory phase. The inhibition of the JAK/STAT pathway limits the pro-inflammatory state in moderate to severe COVID-19 cases. Methods: We analysed the data obtained for an observational cohort of patients with SARS-CoV-2 pneumonia treated with ruxolitinib in 22 hospitals of Mexico. The dose used was determined based on physician’s criteria. The benefit of ruxolitinib was evaluated using the 8-points ordinal scale developed by the NIH in the ACTT1 trial. Duration of hospital stay, changes in pro-inflammatory laboratory values, mortality, and toxicity were also measured. Results: A total of 287 patients administered ruxolitinib were reported at 22 sites in Mexico from March to June 2020; 80.8% received 5 mg BID and 19.16% received 10 mg BID ruxolitinib. At the beginning of treatment, 223 patients were on oxygen support, 59 on invasive ventilation. The percentage of patients on invasive ventilation was 53% in the 10 mg and 13% in the 5 mg cohort. There was a statistically significant improvement measured as a reduction by 2 points (initial 5.39 ± 0.93, final 3.67± 2.98, P value = 0.0001) on the 8-point ordinal scale. There were a total of 74 deaths. Serious adverse events were presented in 6.9% of the patients. Conclusion: Ruxolitinib appears to be safe in COVID-19 patients, with clinical benefits observed in terms of decrease in the 8-point ordinal scale and pro-inflammatory state. Further studies must be done to ensure efficacy against mortality.

Drought stress had a great effect on endogenous hormone in wheat, while endogenous hormone profoundly affects the programmed cell death of endosperm and grain filling. The objectives of this study were (i) to investigate the effect of ethylene and abscisic acid on programmed cell death (PCD) in wheat endosperm cells under post-anthesis drought and (ii) to examine the role of ethylene and abscisic acid in regulating grain filling under post-anthesis drought. The wheat plants were spray solvent (CK), cobalt nitrate (CN) and fluoxone (FU), respectively, under drought stress post anthesis. The samples were then compared with respect to cell viability, nuclear morphometry, cell ultrastructure, DNA integrity, DNA content, DNA hydrolase activity, ABA content, ACC content, grain weight and grain filling rate. Analysis was also conducted about gene transcripts related to PCD and ETH receptors. The results showed that under CN treatment, endosperm PCD was delayed, the duration of high grouting rate was prolonged, and the grain weight was increased, in contrast, the opposite result was obtained under FU treatment.

Design Cross-sectional study Population or sample A total of 447 pregnant women who applied to the¬ pregnancy follow-up outpatient clinic of the Obstetrics and Pediatrics Training and Research Hospital located in the Anatolian side of Istanbul between June and July 2020. Methods The data were obtained through a questionnaire, which involves the demographic, individual, and the obstetric characteristics of the participants as well as their views related to the period of COVID-19 pandemic and expectations for antenatal care services, and the Beck Anxiety Inventory. Main Outcome Measures Incidence and detection rate of anxiety patterns, and frequency of daily activities. Results Anxiety was detected in 60.4% of the pregnants who had participated in our research. It was found out that of the participant, 15.2% of them experienced a decrease in their sleep durations, while 57.5% of them have a reduction in their daily activities, and 64.9% of them experienced an increase in the use of internet throughout the COVID-19 pandemic. Conclusions The need for providing support in antenatal care services increased during the emergency health crisis. Developing new antenatal care strategies and health policies in ensuring the safety of mothers and their infants is needed in pandemic.

The onset of convective instability driven by thermodiffusion of nanoparticles and solute in reactive binary nanofluids is investigated theoretically using linear stability theory and addition factor analysis. A horizontal layer of reactive binary nanofluid at constant and different temperatures and concentrations is taken and the problem is modeled by the system of highly nonlinear partial differential equations. The stability equations are formulated and the expression for Rayleigh number is derived for stationary and oscillatory convections. The effect of nondimentional parameters namely chemical reaction parameter, volume fraction of nanoparticles, Soret coefficients, Prandtl number, heat of reaction parameter and addition factor on stability of the system is shown graphically. The water/ammonia based silver binary nanofluid is considered and the impact of nanoparticles on the stability is studied by employing the Brinkman model for viscosity and Bruggeman model for thermal conductivity. The enhancement of heat transport is analysed by calculating ratio of heat transfer coefficients.

Blue economy comprises about 4.1% of India’s economy of GDP. At present the GDP has declined to 24%, a matter of concern during a Covid-19 pandemic. Hence, the study would appeal to the readership of the Policy holders, Stakeholders, Local Government, Government of India for considering necessary action plan towards the maintainable utilization of ocean resources and sustainable management of Ocean resources and tourism beneath this blue economy through various awareness programs and measures to develop up to pre pandemic level with vigilance of Covid-19 pandemic. A comprehensive plan by the Indian government to setting up regulatory reform to provide an empowering climate for a sustainable ocean economy (e.g., comprehensive, integrated ocean management) and marine spatial planning (MSP) processes and shift harmful subsidies to more sustainable and equitable uses

Plant-soil microbe linkage is theoretically positive, but rarely observed in natural ecosystems. We hypothesized that animal grazing decouples this linkage, for plant removal usually decreases plant influences on soil microbiota. We tested the hypothesis by exploring plant and soil microbial diversity in grazed versus non-grazed grasslands along a gradient of plant diversity. Grazing slightly decreased the diversity of plants and soil microbes in high-diversity sites, but increased them in low-diversity sites. Plant and microbial diversity positively correlated in non-grazed grasslands (P < 0.001), but not in grazed grasslands, indicating that grazing decoupled the biodiversity linkage. The decoupling was attributed to the change of the principal driver of soil microbiota from plant variables in non-grazed grasslands to soil variables in grazed grasslands. The diversity decoupling was also characterized by reduced plant-microbe interactions and lower heterogeneity in grazed grasslands. Our findings provide significant insights into the cross-biota linkages in grassland ecosystems.

Rupture of left ventricular pseudoaneurysm and perforation of right ventricular wall a are very rare.Objective: to investigate the manifestation and contribution of ventriculography, echocardiography, three-dimensional echocardiography, left ventricular contrast echocardiography and right ventricular contrast echocardiography .Methods: we analyzed 12 patients with left ventricular pseudoaneurysm with right ventricular wall perforation, including one from our hospital and 11 from the literature in pubmed database. Results: ①3 cases (25%) were diagnosed by ventriculography, 9 cases (75%) were diagnosed by echocardiography, 2 cases of pseudoaneurysm right ventricular rupture were confirmed by Contrast Echocardiography Of Right Heart, and 1 case was examed by left heart contrast echocardiography. due to the high concentration of contrast agent in the right ventricle, the shunt between the left ventricular pseudoaneurysm and the right ventricular rupture is not obvious. One case of left ventricular aneurysm ruptured into the right ventricle was diagnosed again by three-dimensional ultrasound, and the complementary anatomical information of two-dimensional ultrasound and color Doppler ultrasound could be displayed, and the right ventricular opening could be fully evaluated. ②7 cases underwent operation, of which 1 case died of multiple organ failure, 6 cases were good after operation, and 5 cases were not operated. Conclusion: ①although ventriculography was previously considered as the gold standard for the diagnosis of these rare diseases, echocardiography is also sensitive and accurate in evaluating left ventricular pseudoaneurysm breaking into the right ventricle. ② timely and effective surgical treatment is the key to the prognosis of patients

Background: Patient satisfactions is a widely accepted metric of quality of care. Patient satisfaction is important in understanding the perspectives of the recipients of care and can act as a quality improvement tool. It is of paramount importance to assess patient satisfaction specially after a major healthcare reform. This is the first study to describe the level of patient satisfaction with new Primary Care in Cyprus. Methods: An internationally validated tool for patients’ evaluations of general practice care was used in an online survey in one of the largest group practices in Cyprus Primary Care. An online questionnaire was sent to all registered email addresses of the group practice. A total of 5,000 emails were sent measuring patient satisfaction based on the percentages of patients reporting level of satisfaction on a 5-point Likert scale for the items in the questionnaire. Results: The overall satisfaction percentage was 80.51% (SD 32.36). The vast majority of the questions asked were rated as excellent. Waiting in the waiting room was the item rated poorest with a mean(SD) 4.05 (1.08). The item rated the highest was the safeguarding of patients records and confidentiality with a mean (SD) 0f 4.65(0.70). Conclusions: The first patient satisfaction survey since the introduction of the new NHS in one of the largest Primary care centres seems to demonstrate very high satisfaction rates comparable with other developed EU NHSs. A larger study needs to be performed with more GP practices in order to obtain a national understanding of the patient satisfaction to supplement quality improvement interventions and foster patient empowerment.

Pancreaticoduodenectomy, a procedure rarely performed in children, can lead to significant morbidity. Rhabdomyosarcoma is the most frequent soft tissue sarcoma in pediatrics. Treatment consists of chemotherapy, while local control can be achieved through either surgery, radiotherapy or both. In this brief report, we describe the case of a 15-year-old adolescent who underwent a pancreaticoduodenectomy for a presumed solid pseudopapillary tumor of the head of the pancreas, ultimately diagnosed as a fusion-positive rhabdomyosarcoma. We review the ensuing severe side effects of the treatments, and discuss the role of biopsies for pancreatic tumors in pediatrics.

Myocardial infarction is one of uncommon presentations.we report a55year old women presented with myocardial infarction and found to have polycythemia vera treated with cytoreduction in form of Hydroxyurea 500 mg twice daily with favourable outcome

The emergence of novel coronavirus infectious disease-2019 (COVID-19) in December 2019, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has traumatized the whole world with the ongoing devastating pandemic. After droplet mediated transmission of infectious virus particle, and subsequent tissue tropism through the upper and lower respiratory tract, the acute clinical disease is manifested by severe respiratory illness accompanied by shortness of breath, progressive pneumonia, multi-organ dysfunction and ultimate death in SARS-CoV-2 infected patients. The involvement of other microbial co-infections leading to extortionate ailment in critically ill patients has not been significantly reviewed along with conclusive reporting on underlying molecular mechanisms in COVID-19 patients. Although the incidence of co-infections could be up to 94.2% in laboratory-confirmed COVID-19 cases, the fate of co-infections among SARS-CoV-2 infected hosts often depends on the balance between the host’s protective immunity and immunopathology. The cross-talk between co-pathogens (especially lung microbiomes), SARS-CoV-2 and host is an important factor that ultimately increases the difficulty of diagnosis, treatment, and prognosis of COVID-19, and even increase the symptoms and mortality of the disease. Simultaneously, co-infecting microorganisms may use new strategies to escape host defense mechanisms (by altering both innate and adaptive immune responses) to further aggravate SARS-CoV-2 pathogenesis. This review of literature suggests that clinicians should rule out SARS-CoV-2 infection by ruling in other respiratory co-pathogens, and must have a high index of suspicion for co-infection among COVID-19 patients. Thus, after recognizing the possible pathogens causing co-infection among COVID-19 patients, and the underlying molecular mechanisms of co-infections appropriate curative and preventive interventions can be recommended.

Uptake and internal transport of micronutrients are essential for plant growth, development, and yield. In this regard, Iron Regulated Transporters (IRTs) from the ZIP (Zinc-regulated, iron-regulated transporter-like proteins) family play an important role in transition metal uptake. The majority of studies have been focused on IRT1-like proteins in diploid species, but few in polyploids. Here, we studied the function of TpIRT1A and TpIRT1B homoeologs in a tetraploid crop, Polish wheat (Triticum polonicum). Our results highlighted the importance of TpIRT1 in the uptake and translocation of Fe, Mn, Co, and Cd with direct implications for wheat yield potential. Both TpIRT1A and TpIRT1B were located at the plasma membrane and internal vesicles in Arabidopsis protoplasts, and responsible for Cd and Co sensitivity in yeast. The over-expression of TpIRT1B in A. thaliana increased Fe, Mn, Co, and Cd concentration in its tissues and improved plant growth under Fe, Mn, and Co deficiencies, while caused more sensitive to Cd than wild-type plant. Functional analysis of IRT1 homoeologs from tetraploid and diploid ancestral wheat species in yeast disclosed four distinct amino acid residues in TdiIRT1B (T. dicoccum) and TtuIRT1B (T. turgidum). Together, these results increase the knowledge of IRT1 function in a global crop, wheat.

Worldwide drought events causing tree growth decline and mortality are altering the carbon (C) balance of forest ecosystems. One unexplored aspect of trees’ vulnerability is whether responses to drought may be linked to species’ niche breadth. Using the most severe 2015-2016 El Niño drought event in the last 70 years in Patagonia, we determined pre- and post-drought growth, C reserves, wood isotopes, and vessel diameter in eight angiosperm tree species of contrasting niche breadth across a sharp precipitation gradient in southern Chile. All species responded in unison after the drought with a non-water-conservative response, maintaining growth and C reserves, decreasing δ13C, and increasing both vessel diameter and the soluble sugars:starch ratio relative to pre-drought. We unequivocally showed a functional coordination of organisms’ vital traits, a drought-induced acclimation based on starch conversion into soluble sugars in all of the tree species we examined, regardless of their niche breadth and habitat preference.

Objective: To evaluate the association between prenatal maternal anemia (hemoglobin, Hb<11 g/dl) and long-term respiratory morbidity of the offspring. Methods: A retrospective population-based cohort analysis was performed at the Soroka University Medical Center (SUMC), a single regional tertiary medical center. All singletons born between the years 1991-2014 and discharged alive were included in the study. Offspring with congenital malformations were excluded. The three study groups were defined based on maternal Hb levels, measured upon postpartum discharge: <7.0 (severe anemia), 7.0-11.0 (mild to moderate anemia), and ≥11.0 g/dl (unexposed). Respiratory morbidity diagnosis was based on predefined ICD-9 codes of lung disease definitions, based on the medical records of the hospitalized offspring in SUMC. A Kaplan-Meier survival curve was formed to compare the cumulative respiratory morbidity during the study follow-up period between the study groups, and a multivariable Cox survival analysis was used to control for cofounders. Results: During the study period, 214,305 deliveries met the inclusion criteria. Of those, 807 (0.3%) mothers had severe anemia, 105,196 (49.1%) mothers had mild-moderate anemia, and the remaining were not anemic (108,302, 50.5%). Respiratory hospitalization incidence was found to be significantly higher among the offspring born to anemic mothers (6.2%; 5.3% and 5.1%; p = 0.020, p for trend=0.007 in severe, mild-to-moderate and non-anemic mothers, respectively). The association between maternal anemia and respiratory-related hospitalization of the offspring remained significant among the mild-moderate anemic group after adjusting for confounders in the Cox proportional hazards model (adjusted hazard ratio=1.1; 95% CI 1.05-1.14; p < 0.01). As to the association between severe maternal anemia and offspring morbidity no significant differences were found (p= 0.133), although a linear hazard dose-response ratio was found between the mild-moderate and severe anemic groups (aHR=1.09, aHR 1.24, respectively). Conclusion: Maternal anemia was found to be associated with long-term respiratory morbidity of the offspring.

It is thought that all of the rich content in the present-day Universe based on an array of recent observations developed through gravitational amplification of primeval density fluctuations generated in the very early phase of cosmic evolution. In this paper, we strongly combine machine learning characteristics to achieve very high accuracy levels for the in-silico generation of the RoccuffirnaTM small molecule, a ligand targeted the SARS-COV-2 virus main protease (M pro ) using Quantum Kerr-(A)dS and Myers–Perry black microBlackHole-Inspired Gravitational for both Euclidean and Lorentzian signatures in Practice. We provide also an extensive toolbox of methods for performing quantum schrodinger inspired docking algorithms, teleportation and other information-theoretic tasks in MathCast programming language, and compared these algorithms by means of mean percentile free energy ranking, in a new recall-based evaluation metric for the in-silico design of the Novel Series of the RoccuffirnTMQMMMCoRoNNARRFr anti-(nCoV-19) ligands. In this paper we in-silico designed new drug leads that target the COVID-19 virus main protease (M pro ). M pro, a key CoV enzyme, which plays a pivotal role in mediating viral replication and transcription, and discuss various general results including Galilean transformation to a rigid QMMM heuristic horizon topology, and near-horizon fragmentation symmetry ranging from supergravity theories to enhance the Roccuffirna’s gravity to trap the SARS-COV-2 viruses in practice.

Surface layer protein, which is abundant in the gram-positive bacteria like Lactobacillus sp, for its adherence and symbiotic activity in the normal flora of gastrointestinal tracts. In this study, we showed the relative binding of the SlpAKB290, a homology-based model with a higher binding affinity to ErbB2 rather than the α, β-3integrin-binding domain through molecular docking. The critical binding affinity had been demonstrated with the protein-protein docked clusters’ flexibility and rigidity through the normal mode simulations and thermal unfolding to identify the constraint networks. The results showed a better performance SlpAKB290 with the ErbB2. The current study provided essential insight into the Lactobacilli sp.’s adherence to the host cells through protein-protein interactions.

Although substantial progress has been made in tissue engineered cardiac patch, the translation of such strategies into a clinical setting has always face setbacks due to the lack of appropriate scaffolds and cell resources. Here, we evaluated cardiomyogenic differentiation of electromechanically stimulated rat bone marrow-derived stem cell (rt-BMSCs) on an acellular bovine pericardium (aBP) as well as the performance of this engineered patch in a rat myocardial infarct (MI) model. Briefly, aBP was prepared using a detergent-based decellularization procedure. The formed aBPs were seeded with rt-BMSCs and then stimulated under electrical, mechanical or electromechanical conditions (3-millisecond pulses of 5 V/cm at 1 Hz, 5% streching) to enhance cardiomyogenic differentiation. Thereafter, electromechanically stimulated patch was applied on MI region over a time period (3 weeks). After this period, the retrieved patch and infarct region were evaluated in terms of calcification, inflammatory reaction (CD68), cell migration from patch to host tissue and sarcomere structure related protein expressions. Patch related calcification was not examined in all tested group. Moreover, higher number of BrdU-labelled cells and low level of CD68 positive cells were observed in the infract region under electromechanically stimulated conditions as compared with static conditions. More importantly, MHC, SAC, Troponin T and N-cad positive cells were observed in both infarct region and retrieved engineered patch after the 3 weeks. As a result, we showed that a noticeable differentiation of stem cells on an acellular patch into cardiomyocytes under the electromechanical stimulation. This patch successfully integrated with the host tissue via cell migration from the patch to the infarct region.

Objective To evaluate the expression of soluble human leukocyte antigen G(sHLA-G) in serum of patients with adenomyosis.Methods 34 patients with adenomyosis and 31 patients with uterine fibroids diagnosed histologically were selected as subjects. Serum SHLA-G expression level was detected by enzyme-linked immunosorbent assay (ELISA) in patients with adenomyosis and adenomyoma before and after treatment. while CA125 levels were determined using electrochemiluminescence immunoassay. Results The preoperative serum sHLA-g expression level of the adenomyosis group was significantly higher (18.53 ± 1.435 ng/ml) than that of the fibroids group (28.05 ± 2.466 ng/ml) (P < 0.05). The CA125 level was also significantly higher in patients with adenomyosis than in controls (18.59 ± 1.673 VS 134.8 ± 30.41U/ml; P < 0.05). Serum sHLA-G level in adenomyosis group showed a decreasing trend before and after operation（28.05±14.38 ng/ml、18.41±8.34 ng/ml、14.45±5.77 ng/ml）, serum HLA-G level decreased significantly at 2 days after surgery compared with that before surgery (P < 0.05). sHLA-G decreased more significantly in patients with adenomyosis who underwent total hysterectomy (n=20) than in those who underwent partial hysterectomy (n=14), the sHLA-g level of the patients who underwent total hysterectomy (16.04±4.27ng/ml) was significantly lower than that of the patients who underwent partial hysterectomy (21.79±11.35 ng/ml)(P<0,05).Conclusion Serum sHLA-G is highly expressed in patients with adenomyosis and showed a positive and significant response to therapy. Suggesting that sHLA-G may be closely related to the immune tolerance process of adenomyosis, and is expected to be a serological marker for prognosis assessment of adenomy.

Purpose To investigate the predictive value of serum biomarkers such as AEC、Neutrophil- lymphocyte ratio (NLR) and platelets - lymphocyte ratio(PLR) on immune-related adverse events (irAEs) during the PD-1/PD-L1 inhibitors treatment in advanced malignant tumors. Methods We retrospectively analyzed 95 advanced cancer patients treated with PD-1/PD-L1 inhibitor from January 1, 2017 to May 1, 2020 in our cancer center. Then, the associations between irAEs and PD-1/PD-L1 inhibitors respond was analyzed and the predictive value of serum biomarkers on irAEs occurrence risk was evaluated. Results The incidence of irAEs was 55.8%. There were no statistically significant differences between the irAEs group and the no-irAEs group in Objective response rate (ORR) and Disease control rate (DCR), but the Landmark analysis showed that the irAEs group had better survival after 120 days compared with the no-irAEs group. The incidence of irAEs in the high-AEC and low-NLR groups was greater than that in the low-AEC and high-NLR groups.Univariate logistic analysis results showed that low-NLR, ECOG (0-1) and High-AEC were risk factors for irAEs. However, multivariate logistic analysis not only shows that AEC is an independent factor of irAEs , but also suggests that good ECOG may be more prone to irAEs . Conclusions IrAEs may show a survival benefit to a certain extent. Baseline AEC is a strong predictor of irAEs in the treatment of PD-1/PD-L1 inhibitors.

Colorectal cancer (CRC) is the world’s third most deadly disease, it is very urgent to discover new diagnostic biomarker and therapeutic targets. Interleukin-36α (IL-36α) is a proinflammatory factor, which can initiate the inflammatory response and especially raise the overall systemic Th1 immune response. In the present study, we clarified the new role of IL-36α in colorectal cancer. we observed that IL-36α is down-regulated in human colorectal cancer tissues and colorectal cancer patients with high IL-36α expression had a better prognosis. Then, we constructed IL-36α overexpressing cell lines CT26-IL-36α and HT29-IL-36α to verify the effect of IL-36α on tumor cells. Results showed that IL-36α over-expression could directly inhibit the proliferation, the migration and invasion of tumor cells. We then established CT26 and CT26-IL-36α tumor xenograft model and lung metastasis model to determine the effect of IL-36α in vivo. Results showed that IL-36α overexpression could significantly inhibit the growth and lung metastasis of tumors, and enhance the infiltration and cytokine secretion of CD8+ T lymphocyte cells. Then, we found that CT26-IL-36α secrete more CXCL10 and CXCL11 to enhance the infiltration of CD8+ T lymphocyte than that of CT26-vector cells. These results suggested that IL-36α could serve as a promising therapeutic target for colorectal cancer through directly inhibiting the ability of tumor cells and enhancing the infiltration and function of CD8+ T lymphocytes.
