The acceleration will defocus the radar echo energy and reduce the signal to noise ratio. Second-order Wigner-Ville Distribution (SoWVD)-based detection method can estimate the accelerate speed and achieve higher detection performance. However, SoWVD suffer from huge computational burden for the computation of symmetric autocorrelation function. Comprehensively considering the operation process of SoWVD and defining an improved autocorrelation function, a frequency method for the fast implementation of SoWVD is proposed in this paper. The proposed algorithm reduces the computational complexity of SoWVD by one order of magnitude, and does not change the anti-noise performance of the algorithm.

Objective To assess depression at 2(M2), 6(M6), and 12(M12) postpartum months among women with postpartum haemorrhage (PPH) compared with women with no PPH and, to describe anxiety and post-traumatic stress disorder (PTSD). Design Repeated cross-sectional study within a prospective cohort of women in the immediate postpartum period. Setting Single-centre study at a French level 3 maternity unit. Population Women who gave birth at ≥22 weeks of gestation were eligible. The exposed group comprised the women who had had a primary PPH (≥500 mL in the 24 hours after delivery) and the unexposed group, which did not. Methods 1298 included women (528 with and 770 without PPH) completed self-administered questionnaires. Main Outcome Measures The prevalence of depression and its mean scores, at M2, M6, and M12 and secondary, the prevalence of anxiety and of PTSD and its mean scores, measured at the same times. Results At M2, the prevalence of depression and PTSD was higher among the women with PPH (24.4% vs 18.2%, p=0.03, and 12.8% vs 7.6%, p=0.02). The prevalence of anxiety at inclusion and M2 was higher in the PPH group (18.1% vs 10.3%, p=0.01, and 20.0% vs 13.3%, p=0.01). At M6, and M12, only the mean adjusted PTSD score was higher in the PPH group (7.6, 95%CI, 6.3-9.1 vs 5.8%, 95%CI, 4.9-6.8, p=0.02). Conclusions Professionals must know these high rates and screen for psychological disorders during the long postpartum period. Funding Grant from the Clermont-Ferrand University Hospital AOI2015.

Title : Effect of Mepolizumab on reducing ANCA levels in eosinophilic granulomatosis with polyangiitis: a case series and review of the literature

Spontaneous retroperitoneal hematoma is a rare complication of anticoagulation therapy. Presentation may vary from limb paresis to hypovolemic shock due to blood loss. The optimal treatment is controversial as it can be managed conservatively or surgically. We report a case of spontaneously occurring iliopsoas hematoma in a patient on anticoagulation post pulmonary thromboendarterectomy (PTE) surgery.

IntroductionThe number of students enrolled in online and distance education courses has been increasing since 2000 (Allen & Seaman, 2013). In the fall of 2015, there were 5,954,121 students enrolled in any distance education courses at degree-granting postsecondary institutions (U.S. Department of Education, 2015). This increase in virtual education had brought about pedagogical changes and adaptations that have altered the roles of the educator and learner, and had reshaped the environment in which they interact. According to the 2017 distance enrollment report by theDigital Learning Compass , the number of students who have enrolled in online courses had surpassed six million nationally, continuing a growth trend that has been consistent for 13 years (Allen & Seaman, 2017). Additionally, more than a quarter of higher education students (29.7 percent) in the United States have enrolled in at least one online course (Online Learning Consortium, 2017). The purpose of this study was to examine predictors of success for online learners. To this end, the researchers sought to further understand whether familiarity with and access to technology, employment status, academic readiness are predictors of grade point average and satisfactions for students enrolled in online courses.

Mitral regurgitation in Barlow disease may still be challenging to be repaired . Most often it involves the posterior leaflet . Many techniques and concepts are currently available ; the main goal being to restore a good surface of coaptation . Basic principles such a thorough analysis is still required whatever the approach to assess excess tissue height , width and prolapse . Nowadays it seems that two different ways of treating mitral prolapse coexist : the non resection one and the resection one .Both will be discussed and analysed . Similarly the use of artificial chordae seem to have a preponderant role to support the free edge and correct a prolapse . Native secondary chord transfer are easy and reliable but seem abandoned by many . Anterior leaflet prolapse is also dealt with and fewer options are available to address this leaflet . Then commissural prolapse is mentioned . It is an important area of the valve which should deserve better treatment than commissuroplasty . Finally a special entity will be described ; mitro annular disjonction . The approach is not or no longer an issue as only good long term results are important in an era where per cutaneous therapy is the only non invasive technique .

Automatic modulation classification (AMC) plays an important role in various applications such as cognitive radio and dynamic spectrum access. Many research works have been exploring deep learning (DL) based AMC, but they primarily focus on single-carrier signals. With the advent of various multicarrier waveforms, the authors propose to revisit DL-based AMC to consider the diversity and complexity of these novel transmission waveforms in this letter. Specifically, the authors develop a novel representation of multicarrier signals and use suitable networks for classification. In addition, to cope with non-target signals, support vector data description (SVDD) is applied with the activations of the networks’ hidden layer. Experimental results demonstrate the effectiveness of the proposed scheme.

Background: Moderate to severe atopic dermatitis (AD) is difficult to treat. There are rare reports on the treatment of moderate to severe AD by lowering serum IgE with a combination of methotrexate (MTX) and azathioprine (AZA) and hence improving symptoms. Objective: This study aimed to improve AD symptoms by lowering serum IgE with a combination therapy of MTX and AZA. Design: Retrospective cohort study of patients treated during 2013 and 2019. Setting: Patients recruited from a tertiary care university hospital in Taiwan. Participants: Sixty-five (case group) and 36 (control group) patients with moderate to severe AD, aged between 10 and 77 years. Measurements: Patients in the case group received a combination of MTX (15 mg weekly) and AZA (150 mg daily) for 1 to 5 years. Patients in the control group received any therapies other than this combination. Serum total IgE levels were checked periodically in both groups. Results: Serum total IgE was markedly reduced in the case group. For example, the cumulative success rates of a 50% IgE reduction in the case group in year 1 and year 5 were 69.2% and 98.5%, respectively, compared to 10.0% and 18.2% in the control group (hazard ratio 14.8; p < 0.001). At the end of year 4, the cumulative success rate of IgE reduction to below the normal range was 41.1% in the case group and 3.4% in the control group (hazard ratio 6.71; p = 0.033). Regarding adverse events, the rates of abnormal white blood cell counts, hemoglobin, platelet counts, and alanine aminotransferase were not increased in the case group compared to the control group. Conclusion: Combination therapy with MTX and AZA was effective in treating patients with intractable AD by reducing their serum total IgE levels.

Oral –gut Microbium and its impact on general health: systematic reivews

In this study, we developed two new whole-cell biocatalysts by immobilizing aminopeptidase (Aps) on the surface of yeast cells, using N-terminal fusion and C-terminal fusion through lectin mediated display system. After the two strains were cultured in the medium with galactose as inducer for 48 hours, the activity of expressing Aps was at a high level of 0.25 U/OD600/mL and 0.12 U/OD600/mL. The correct location of Aps was confirmed by immunofluorescence analysis and flow cytometry. Afterwards two whole cell catalysts could be reused with high stability as it retained more than 70% of initial activity after ten repeated batch reactions. Using β-cypermethrin (β-CP) as a substrate, the effectiveness of two new whole-cell catalysts in the treatment of highly hydrophobic organic pollutants was evaluated. The results showed that when the concentration of β-CP was 200 mg·L -1, the hydrolysis rates of the two whole cell catalysts were 33.16 μmol·L -1·day -1 and 28.99 μmol·L -1·day -1, and has the ability to degrade a variety of pyrethroid pesticides. The β-CP residue in lettuce and cherry tomatoes could be removed more than 70% under the conditions of the Aga2N-Aps whole cell catalyst preparation dilution of 100 times. This is the first report on the development of surface display Aps biocatalyst, which can be used as an effective and renewable alternative for the treatment of highly hydrophobic organic pollutants.

Severe traumatic brain injury is a leading cause of death and disability worldwide, resulting in a significant individual and socioeconomic burden. We present two cases of severe traumatic brain injury with surprisingly encouraging outcomes. We attribute this to the additional combined administration of citicoline and cerebrolysin.

Congenital hyporhinia or partial arrhinia is a very rare congenital abnormality of nasal embryogenesis with unknown etiology. It is commonly associated with other craniofacial anomalies which are thought to be caused by an absent or rudimentary nose. A case of congenital hyporhinia with associated other anomalies is presented and discussed.

71-year-old male with epidural spinal lipomatosis and spondylolisthesis. Conservative treatment failed, and a spinal fusion and laminectomy were performed. Postoperatively, the patient reported a reduction in pain; however, the pain recurred soon after surgery. After losing 53 pounds with medical management, the patient reported a complete absence of pain.

TOPOGRAPHY PREDICTION RESULTS

Atomic force microscopy (AFM) is routinely used as a metrological tool among diverse scientific and engineering disciplines. A typical AFM, however, is intrinsically limited by low throughput and is inoperable under extreme conditions. Thus, this work attempts to provide an alternative with a conventional optical microscope (OM) by training a deep learning model to predict surface topography from surface OM images. The feasibility of our novel methodology is shown with germanium-on-nothing (GON) samples, which are self-assembled structures that undergo surface and sub-surface morphological transformations upon high-temperature annealing. Their transformed surface topographies are predicted based on OM-AFM correlation of 3 different surfaces, bearing an error of about 15% with 1.72× resolution upscale from OM to AFM. The OM-based approach brings about significant improvement in topography measurement throughput (equivalent to OM acquisition rate, up to 200 frames per second) and area (∼1 mm²). Furthermore, this method is operable even under extreme environments when an _in-situ_ measurement is impossible. Based on such competence, we also demonstrate the model’s simultaneous application in further specimen analysis, namely surface morphological classification and simulation of dynamic surfaces’ transformation.

Although previously confined to regions within Africa, Lumpy Skin Disease Virus (LSDV) infections have caused significantly large outbreaks in several regions of the world in very recent years. In 2019, an outbreak of the disease was reported from India with low rates of morbidity and no reported mortality. However, in 2022, an ongoing outbreak of LSDV spanning over 7 states in India resulted in a reported mortality of over 80,000 cattle over a short period of three months. Here, we report complete genome sequences of 6 viral isolates of LSDV collected from affected cattle during an ongoing outbreak of the disease in Rajasthan, India. Analysis of the viral sequences suggests the genomes from the 2022 outbreak harbour a large number of genetic variations compared to the reference genome and form a distinct lineage. This report also highlights the importance of genome sequencing and surveillance of transboundary infectious agents and genomic characterisation of outbreaks.

Each year, seasonal bird migration leads to an immense redistribution of species occurrence and abundances, with pervasive, though unclear, consequences for patterns of multi-faceted avian diversity. Here, we uncover stark disparities in spatiotemporal variation between avian taxonomic and functional diversity across the continental US. In the eastern US, the temporal patterns of taxonomic and functional diversity are diametrically opposed, with functional richness highest in winter despite seasonal loss of species, and the remaining most abundant species amassed in a few regions of the functional space that likely reflect the resources available in winter. In contrast, in the western US, both species and functional richness are high during the breeding season, and species' abundances are regularly distributed and widely spread across the functional space. We anticipate that the uncovered complexity of spatiotemporal associations among avian diversity measures will be the catalyst for adopting an explicitly temporal framework for multi-faceted biodiversity analysis.

Background and purpose Activation of indoleamine 2,3-dioxygenase (IDO) in prefrontal cortex (PFC) is closely related to depression. It has been proved that prelimbic (PrL) and infralimbic (IL) regions of medial PFC are involved in emotion regulation, and may play distinct roles in regulation of depression. However, the mechanism of how IDO in PrL or IL affects depressive behaviors remains unclear. Experimental approach IDO inhibitor 1-MT was directly injected into PrL and IL of depressive rats induced by ICV-STZ, respectively. Depressive- and anxiety-behaviors were evaluated in forced swim test, sucrose preference test, novelty-suppressed feeding test, novel object recognition test and open field test. HPLC‒MS/MS detected kynurenine metabolites, ELISA detected cytokines, Western blot examined protein expression and Golgi staining assessed synaptic plasticity. Immunofluorescence staining was used to observe the expression and morphology of glial cells. Key results Dissimilar abnormalities were observed in PrL and IL of ICV-STZ depressed rats. In PrL, astrocyte defects were manifested, including reduced GFAP-positive cells, glial transporters and kynurenic acid, and morphological damage. In IL, microglial overactivation was manifested by increased cytokines, Iba1-positive cells and 3-hydroxy-kynurenine, accompanied by morphological alterations. Meanwhile, synaptic plasticity was decreased in both subregions. Microinjection of 1-MT at PrL or IL may improve depressive behaviors by reversing these different abnormalities in PrL and IL, respectively, without influencing anxiety behavior. Conclusions and implications Overall, the antidepressant effects of 1-MT by inhibiting IDO in PrL or IL are realized through different pathways, that is, by enhancing neuroprotective effects in PrL and attenuating neurotoxic response in IL.

Retroperitoneal dedifferentiated liposarcoma recurred within 5 months after the first complete surgical resection under the naked eye. After recurrence, extended radical surgical resection was performed, and there was no sign of recurrence or metastasis after 13 months.

Spontaneous extradural hematoma in Sickle cell disease is rare neurological complication with few cases reported in the English literature. We report a case of a 16-year old male diagnosed with Sickle Cell Beta Thalassemia who demonstrated right sided acute parietal extradural hematoma with mass effect.

Tuberculous meningitis is possibly complicated with multiple cerebral infarctions and basal meningitis, and the mortality and neurological prognosis is reportedly poor. This case suggested that clinicians should consider tuberculous meningitis as a differential diagnosis of patients with disturbed consciousness in an aging country Japan.

Our previous studies indicated that endophyte M7SB41 ( Seimatosporium sp .) can significantly enhance host plants powdery mildew (PM) resistance. To recover the mechanisms, differentially expressed genes (DEGs) were compared between E+ (endophte-inoculated) and E- (endophyte-free) plants by transcriptomics. A total of 4094, 1200 and 2319 DEGs between E+ and E- were identified at 0, 24 and 72h after plants infected with PM pathogen Erysiphe cichoracearum, respectively. Gene expression pattern analysis displayed a considerable difference and temporality in response to PM stress between the two groups. Transcriptional profiling analysis revealed that M7SB41 induced plants resistance to PM through Ca 2+ signaling, salicylic acid （SA）signaling and phenylpropanoid biosynthesis pathway . In particular, we investigated the role and the timing of the SA and jasmonic acid (JA)-regulated defensive pathways. Both transcriptomes and pot experiments showed that SA-signaling may play a prominent role in PM resistance conferred by M7SB41. Additionally, the colonization of M7SB41 could effectively increase the activities and the expression of defense-related enzymes under PM pathogen stress. Meanwhile, our study revealed reliable candidate genes from TGA, WRKY and pathogenesis-related genes related to M7SB41-mediate resistance. These findings offer a novel insight into the mechanisms of endophytes in activating plant defense responses.

Aim: Interferons (IFNs) have been identified as a potential treatment alternative for Coronavirus Disease 19 (COVID-19). This study assessed the safety, tolerability, bioavailability, and biological activity of inhaled interferon-α2b (IFN-α2b) in healthy adults. Methods: A double-blind, randomized, phase 1 clinical trial was conducted with two cohorts of healthy subjects aged 18-50 years old. The first cohort received 2.5 MIU of inhaled IFN-α2b twice daily for 10 days (n=6) or placebo (n=3); the second cohort received 5.0 MIU of inhaled IFN-α2b in a similar scheme (n=6) or placebo (n=3). The first two doses were administered in an Emergency Department, then participants completed their treatment at home. Safety was measured through vital signs, new symptoms, and laboratory tests. Tolerability was measured as the participant´s treatment acceptability. Bioavailability and biological activity were measured from serum IFNα levels and real-time quantitative PCR of interferon-induced genes in blood before and after treatments. Results: Exposure to inhaled IFN-α2b at 2.5 MIU or 5 MIU doses did not produce significant changes in participant vital signs, or elicit new symptoms, and standard hematological and biochemical blood measurements were comparable to those recorded in individuals who received placebo. All adverse events were mild or moderate and did not require medical care. Participants reported very high tolerability. A dose-dependent mild increase in serum IFN-α concentrations and an increase in serum RNA expression of IFN-induced genes were observed after treatment. Conclusion: Inhaled IFN-α2b was safe, well-tolerated, and induced systemic biological activity in healthy subjects.
