Background: Direct oral anticoagulants (DOACs) pose a great challenge for physicians in life-threatening bleeding events. The aim of this study was to test the efficacy of reversing the DOAC rivaroxaban using four-factor PCC (prothrombin complex concentrate), a non-specific reversing agent. Methods: Patients with life-threatening bleeding events during rivaroxaban treatment were included and administered 25 U kg-1 of PCC. Blood samples were collected immediately prior to as well as after PCC treatment at predefined time intervals...

Alcohol addiction is accompanied by aberrant neural activity. Previously, task-based fMRI and resting-state EEG studies have revealed that craving, a critical component of addiction, is linked to abnormal activity in cortical regions including the dorsal anterior cingulate cortex (dACC), nucleus accumbens (NAcc), posterior cingulate cortex (PCC) and pregenual anterior cingulate cortex (pgACC), etc. In this study, we combine these two imaging techniques to investigate a group of alcohol-addicted patients and provide convergent evidence for the neural correlates of craving not only in alcohol but substance abuse in general...

INTRODUCTION: Life-threatening bleeding can complicate warfarin therapy. Rapid anticoagulant reversal via replacement of vitamin-K dependent clotting factors is essential for hemostasis. We compare two methods of rapid factor replacement for warfarin reversal. METHODS: A retrospective cohort study of warfarin-treated patients experiencing life-threatening bleeding who received a reversal protocol comprised of 4F PCC or 3F PCC and rFVIIa was performed. Demographic, clinical and anticoagulant reversal information, and all adverse events attributed to warfarin reversal were recorded...

An important feature offered by marine cyanobacterial strains over freshwater strains is the capacity to grow in seawater, replacing the need for often-limited freshwater. However, there are only limited numbers of marine cyanobacteria that are available for genetic manipulation and bioprocess applications. The marine unicellular cyanobacteria Synechococcus sp. strain NKBG 15041c (NKBG15041c) has been extensively studied. Recombinant DNA technologies are available for this strain, and its genomic information has been elucidated...

Default mode network (DMN) has discernable involvement in the representation of negative, self-referential information in depression. Both increased and decreased resting-state functional connectivity between the anterior and posterior DMN have been observed in depression. These conflicting connectivity differences necessitated further exploration of the resting-state DMN dysfunction in depression. Hence, we investigated the time-varying dynamic interactions within the DMN via functional connectivity microstates in a sub-second level...

Serotonin 1A (5-HT1A ) receptors play a direct role in neuronal development, cell proliferation, and dendritic branching. We hypothesized that variability in 5-HT1A binding can affect cortical thickness, and may account for a subtype of major depressive disorder (MDD) in which both are altered. To evaluate this, we measured cortical thickness from structural magnetic resonance imaging (MRI) and 5-HT1A binding by positron emission tomography (PET) in an exploratory study. To examine a range of 5-HT1A binding and cortical thickness values, we recruited 25 healthy controls and 19 patients with MDD...

Phycobilisomes (PBSs) are supramolecular pigment-protein complexes that serve as light-harvesting antennae in cyanobacteria. They are built up by phycobiliproteins assembled into allophycocyanin core cylinders (ensuring the physical interaction with the photosystems) and phycocyanin rods (protruding from the cores and having light-harvesting function), the whole PBSs structure being maintained by linker proteins. PBSs play major role in light-harvesting optimization in cyanobacteria; therefore, the characterization of their structural integrity in intact cells is of great importance...

Cyanobacteria are an important group of microorganisms displaying a range of morphologies that enable phenotypic differentiation between the major lineages of cyanobacteria, often to the genus level, but rarely to species or strain level. We focused on the unicellular genus Synechocystis that includes the model cyanobacterial strain PCC 6803. For 11 Synechocystis members obtained from cell culture collections, we sequenced the variable part of the 16S rRNA-encoding region and the 16S - 23S internally transcribed spacer (ITS), both standardly used in taxonomy...

PURPOSE: Results of a study of anticoagulation reversal agent availability in rural and community hospital emergency departments (EDs) are reported. METHODS: A cross-sectional telephone survey was conducted to test the hypothesis that anticoagulation reversal agents are not commonly stocked in low-volume EDs. In phase 1 of the study, a physician, pharmacist, or nurse manager at a sample of EDs in 1 state was surveyed to characterize anticoagulation reversal agent availability and the presence or absence of reversal protocols; in phase 2, follow-up qualitative interviews were conducted with hospital pharmacists selected by purposive sampling to identify barriers to availability...

Photosystem I (PSI) is a Type-I reaction center and the largest photosynthetic complex to be characterized. In cyanobacteria, PSI is organized as a trimer with a three-fold axis of symmetry. Recently, a tetrameric form of PSI has been identified in cyanobacteria. Plastids in plants and algae only contain monomeric PSI, suggesting that tetrameric PSI may be key in the transition from ancestral cyanobacterial trimeric PSI to plant/algal monomeric PSI. We have investigated the kinetics of e- transfer to the initial acceptor in PSI tetramer isolated from Chroococcidiopsis TS-821...

Person-centered care (PCC) is a central feature of health care reform, yet the tools needed to deliver this practice have not been implemented consistently. Person-centered care planning (PCCP) is a treatment planning approach operationalizing the values of recovery. To better understand PCCP implementation, this study examined the relationship between recovery knowledge and self-reported PCCP behaviors among 224 community mental health center staff. Results indicated that increased knowledge decreased the likelihood of endorsing non-recovery implementation barriers and self-reporting a high level of PCCP implementation...
