Background: Regional variations in reperfusion times and mortality in patients with ST-segment elevation myocardial infarction (STEMI) are influenced by differences in coordinating care between emergency medical services (EMS) and hospitals. Building on the Accelerator-1 Project, we hypothesized that time to reperfusion could be further reduced with enhanced regional efforts. Methods: Between April 2015 and March 2017, we worked with 12 metropolitan regions across the United States with 132 PCI-capable hospitals and 946 EMS agencies...

Malignant gonadal germ cell tumors, referred to as germ cell cancers (GCC), occur with increased frequency in individuals who have specific types of differences (disorders) of sex development (DSD). Recent population-based studies have identified new environmental and genetic risk factors that have led to a 'genvironment' hypothesis, which may potentially be helpful in risk assessment in DSD-related GCC. In DSD, the malignancy risk is highly heterogeneous, but recent studies allow now to discriminate between high- and low-risk conditions...

Heterobifunctional molecules that recruit E3 ubiquitin ligases, such as cereblon, for targeted protein degradation represent an emerging pharmacological strategy. A major unanswered question is how generally applicable this strategy is to all protein targets. In this study, we designed a multi-kinase degrader by conjugating a highly promiscuous kinase inhibitor with a cereblon-binding ligand, and used quantitative proteomics to discover 28 kinases, including BTK, PTK2, PTK2B, FLT3, AURKA, AURKB, TEC, ULK1, ITK, and nine members of the CDK family, as degradable...

Increasing use of wearable electronic devices have resulted in enhanced demand for highly flexible supercapacitor electrodes with superior electrochemical performance. In this study, flexible composite membranes with electrosprayed MnO2 particles uniformly anchored on Fe3O4 doped electrospun carbon nanofibers (Fe3O4@CNFMn) have been prepared as flexible electrodes for high-performance supercapacitors. The interconnected porous beaded structure ensures free movement of electrolyte within the composite membranes, therefore, the developed supercapacitor electrodes not only offer high specific capacitance of ~306 F/g, but also exhibit good capacitance retention of ~85% after 2000 cycles, which certify that the synthesized electrodes offer high and stable electrochemical performance...

Splenic lymphangiomas are exceedingly rare benign neoplasms that occur mainly in children. They are commonly seen in the neck and axillary region. Abdominal lymphangiomas accounts for less than 5% of cases. So far, fewer than 100 cases of spleen lymphangiomas have been reported in the literature. In this paper, we present one case of solitary splenic lymphangioma in a 34-year-old woman who presented with abdominal pain and weight loss for one month. The patient underwent splenectomy and diagnosis was confirmed by histopathology and immunohistochemistry studies...

Autophagy is a cellular process for maintaining cellular homeostasis. This process can be induced by different factors, such as immune stimuli and pathogen-associated molecules. Autophagy has an important role in the control of IL-1β secretion by macrophages and other cell types. In present study, we describe a novel role for Iraqi propolis affecting autophagy in controlling the secretion of IL-1β in bone-marrow macrophages (BMDMs). After infection with Pseudomonas aeruginosa in the presence of propolis, the degradation of IL-1β was induced, and the activity of inflammasome was reduced...

In most bacteria, the essential targets of β-lactam antibiotics are the D,D-transpeptidases that catalyze the last step of peptidoglycan polymerization by forming 4→3 cross-links. The peptidoglycan of Clostridium difficile is unusual since it mainly contains 3→3 cross-links generated by L,D-transpeptidases. To gain insight into the characteristics of C. difficile peptidoglycan cross-linking enzymes, we have purified the three putative C. difficile L,D-transpeptidases paralogues, LdtCd1, LdtCd2, and LdtCd3, which have been previously identified by sequence analysis...

Brain Computer Interfaces (BCIs) serve as an integration tool between acquired brain signals and external devices. Precise classification of the acquired brain signals with the least misclassification error is an arduous task. Existing techniques for classification of multi-class motor imagery electroencephalogram (EEG) have low accuracy and are computationally inefficient. This paper introduces a classification algorithm, which uses two frequency ranges, mu and beta rythms, for feature extraction using common spatial pattern (CSP) along with support vector machine (SVM) for classification...
