Ammonia nitrogen removal from coking wastewater and high quality gypsum recovery by struvite recycling by using calcium hydroxide as decomposer.

J Environ Manage 2021 May 12;292:112712. Epub 2021 May 12.

School of Environment and Civil Engineering, Dongguan University of Technology, Dongguan, 523808, China.

This study deals with the highly significant and cost-effective pretreatment of the high concentration of the Total Ammonia Nitrogen (TAN) in coking wastewater to improve the biodegradability. Struvite crystallization is a promising process for TAN removal, but the high operating cost hinders its application. To solve this problem, a novel struvite recycling process was proposed for pre-treating TAN present in the coking wastewater, within which struvite was decomposed in the solid-liquid system using Ca(OH) as the decomposer.

Pre-saccadic attention spreads to stimuli forming a perceptual group with the saccade target.

Cortex 2021 Apr 15;140:179-198. Epub 2021 Apr 15.

Berlin School of Mind and Brain, Humboldt-Universität zu Berlin, Germany; Department of Psychology, Humboldt-Universität zu Berlin, Germany; Exzellenzcluster Science of Intelligence, Technische Universität Berlin, Berlin, Germany.

The pre-saccadic attention shift-a rapid increase in visual sensitivity at the target-is an inevitable precursor of saccadic eye movements. Saccade targets are often parts of the objects that are of interest to the active observer. Although the link between saccades and covert attention shifts is well established, it remains unclear if pre-saccadic attention selects the location of the eye movement target or rather the entire object that occupies this location.

Pre-transplant red blood cell and platelet transfusion burden in de novo myelodysplastic syndrome undergoing allogeneic transplantation: Pre-transplant red blood cell and platelet transfusion burden in de novo MDS after allogeneic transplantation.

Transplant Cell Ther 2021 May 12. Epub 2021 May 12.

Japanese Data Center for Hematopoietic Cell Transplantation, Nagoya, Japan; Department of Healthcare Administration, Nagoya University Graduate School of Medicine, Nagoya, Japan.

Background: Most patients of myelodysplastic syndrome (MDS) require red blood cell (RBC) and/or platelet transfusion during their disease courses, which could cause an increased risk of iron overload and alloimmunization.

LayNii: A software suite for layer-fMRI.

Neuroimage 2021 May 12:118091. Epub 2021 May 12.

Brain Innovation, Maastricht, Netherlands.

High-resolution fMRI in the sub-millimeter regime allows researchers to resolve brain activity across cortical layers and columns non-invasively. While these high-resolution data make it possible to address novel questions of directional information flow within and across brain circuits, the corresponding data analyses are challenged by MRI artifacts, including image blurring, image distortions, low SNR, and restricted coverage. These challenges often result in insufficient spatial accuracy of conventional analysis pipelines. Read More

Department of Electrical Engineering, College of Engineering, American University of Sharjah, ESB-2018, Engineering Science Building, American University of Sharjah, University City, Sharjah, 26666, United Arab Emirate. Electronic address:

In this paper, we investigate the forelimbs somatosensory evoked potential (SSEP) signals, which are representative of the integrity of ascending sensory pathways and their stability as well as function, recorded from corresponding cortices, post thoracic spinal cord injury (SCI). We designed a series of distinctive transection SCI to investigate whether forelimbs SSEPs change after right T10 hemi-transection, T8 and T10 double hemi-transection and T8 complete transection in rat model of SCI. We used electrical stimuli to stimulate median nerves and recorded SSEPs from left and right somatosensory areas of both cortices. Read More

Structure-guided design of ultrapotent disruptive IgE inhibitors to rapidly terminate acute allergic reactions.

J Allergy Clin Immunol 2021 May 12. Epub 2021 May 12.

Department of Structural Biology, Stanford University School of Medicine, Stanford California 94305; Progam in Immunology, Stanford University School of Medicine, Stanford California 94305; Sean N. Parker Center for Allergy Research at Stanford University. Electronic address:

Background: Anaphylaxis represents one of the most severe and fatal forms of allergic reactions. Like most other allergies, it is caused upon activation of basophils and mast cells by allergen-mediated cross-linking of immunoglobulin E (IgE) bound to its high affinity receptor FcεRI on the cell surface. The systemic release of soluble mediators induces an inflammatory cascade rapidly causing symptoms with peak severity in minutes to hours after allergen exposure. Read More

Association between a pre-admission limitation in walking ability and post-discharge adverse outcomes among hospitalized patients with heart failure: Report from a multicenter prospective cohort study.

Int J Cardiol 2021 May 12. Epub 2021 May 12.

Department of Integrated Health Sciences, Nagoya University Graduate School of Medicine, Nagoya, Japan. Electronic address:

Background Although limited walking ability at discharge is a known risk factor for adverse outcomes in older patients with heart failure (HF), the association between pre-admission limitations and adverse outcomes is unknown. Therefore, we evaluated the prevalence of a pre-admission limitation in walking ability and its relationship with post-discharge outcomes among patients with HF with reduced, mid-range, and preserved left-ventricular ejection fraction (HFrEF, HFmrEF, and HFpEF). Methods We followed 2042 patients aged ≥65 years (HFrEF, n = 668; HFmrEF, n = 360; HFpEF, n = 1014) from a multicenter cohort study in Japan. Read More

The use of statistical modelling to identify important parameters for the shape of the torso following surgery for adolescent idiopathic scoliosis.

J Anat 2021 May 15. Epub 2021 May 15.

Institute of Clinical Science, University of Birmingham, Birmingham, UK.

The surgical strategy in adolescent idiopathic scoliosis (AIS) aims to recreate the symmetry of the torso. This requires the minimisation of both the size of the scoliosis and the angulation between the sides of the torso, along with the recreation of a normal thoracic kyphosis. This study uses predictive modelling to identify the significance of the value of the pre-operative parameters, and the change in the magnitude of the parameters as a result of an operation on the shape of the torso using the 'most prominent points'; two areas of maximum prominence on either side of the spine with x, y and z coordinates.

Incidence, characteristics and clinical profile of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in patients with pre-existing primary immune thrombocytopenia (ITP) in Spain.

Br J Haematol 2021 May 15. Epub 2021 May 15.

Hospital Universitario Virgen del Rocío, Sevilla, Spain.

Infections are one of the well-known precipitating factors for relapses in patients with immune thrombocytopenia (ITP). Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can sometimes lead to or be associated with thrombocytopenia due to an increase in peripheral platelet destruction from inflammatory hyperactivation. Currently, we do not know if SARS-CoV-2 infection modifies the natural evolution of chronic or persistent ITP or if previous immunosuppression of patients with ITP influences the incidence and severity of coronavirus disease 2019 (COVID-19) in this group.

Coronavirus Disease 2019 (COVID-19) Vaccines: A Concise Review.

Oral Dis 2021 May 15. Epub 2021 May 15.

Department of Preventive and Restorative Dentistry, College of Dental Medicine, University of Sharjah, UAE.

The development of a successful vaccine against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the agent of coronavirus disease 2019 (COVID-19), in an unmatched period of ten months, is a tribute to human ingenuity in the face of a vicious pandemic. A return to pre-pandemic `normalcy` depends on the successful delivery of the vaccine to a majority (~70%) so as to develop herd immunity critical to arrest the community spread of infection. Vaccination against COVID-19 is particularly important for dentistry as the dental team works in an environment replete with aerosol-generating procedures (AGP) that facilitate virus spread.
