Banked blood exhibits impairments in nitric oxide (NO)-based oxygen delivery capability, reflected in rapid depletion of S-nitrosohemoglobin (SNO-Hb). We hypothesized that transfusion of even freshly-stored blood used in pediatric heart surgery would reduce SNO-Hb levels and worsen outcome. In a retrospective review (n = 29), the percent of estimated blood volume (% eBV) replaced by transfusion directly correlated with ventilator time and inversely correlated with kidney function; similar results were obtained in a prospective arm (n = 20)...

Acute rerupture after coil embolization is defined as rerupture within three days after treatment; its prognosis is worse than that of rebleeding at other time periods. However, to date, little is known about complications during the acute phase. Therefore, we used the PubMed database to perform a review of acute rerupture after coil embolization of ruptured intracranial saccular aneurysms and increase our understanding. After reviewing the complications, we found that the cause of acute rerupture is unclear, but the following risk factors are involved: incomplete occlusion of the initial aneurysm, the presence of a hematoma adjacent to a ruptured aneurysm, an aneurysmal outpouching, poor Hunt-Hess grade at the time of treatment, and the location of the aneurysm in an anterior communicating artery...

PURPOSE: To establish a cardiac signal from scattering matrix or scattering coefficient measurements made on a 7T 8-channel parallel transmit (pTx) system, and to evaluate its use for cardiac gating. METHODS: Measurements of the scattering matrix and scattering coefficients were acquired using a monitoring pulse sequence and during a standard cine acquisition, respectively. Postprocessing used an independent component analysis and gating feature identification. The effect of the phase of the excitation radiofrequency (RF) field ( B1+ shim) on the cardiac signal was simulated for multiple B1+ shim configurations, and cine images were reconstructed from both the scattering coefficients and electrocardiogram (ECG)...

The accumulation of visceral adiposity is strongly associated with systemic inflammation and increased cardiometabolic risk. WNT5A, a non-canonical WNT ligand, has been shown to promote adipose tissue inflammation and insulin resistance in animal studies. Among other non-canonical pathways, WNT5A activates planar cell polarity (PCP) signaling. The current study investigated the potential contribution of non-canonical WNT5A/PCP signaling to visceral adipose tissue (VAT) inflammation and associated metabolic dysfunction in individuals with obesity...

Curcumin is the main curcuminoid found in turmeric rhizomes and is a strong candidate to formulate foodstuff with specific properties. Among various bioactive properties of curcumin, its antiinflammatory activity is remarkable; on the other hand, its low water solubility leads to low absorption. Thus, new formulations need to be developed to improve its efficacy, and encapsulation is a promising alternative strategy in this regard. The objective of the present study was to obtain curcumin-loaded polyvinylpyrrolidone (PVP) nanoparticles and evaluate their acute in vivo antiinflammatory activity...

BACKGROUND: While accumulating evidence suggests that vitamin D deficiency may be involved in the risk to develop schizophrenia and its outcome, there are no studies on vitamin D supplementation in this context. We sought to assess the effect of vitamin D supplementation on psychiatric, cognitive and metabolic parameters in chronic clozapine-treated schizophrenia patients. METHODS: This eight-week, randomized, double-blind, placebo-controlled clinical trial, recruited schizophrenia patients who had been maintained on clozapine treatment for at least 18weeks and had low levels of vitamin D (<75nmol/l) and total PANSS scores >70 (to ascertain the presence of residual symptoms)...

Sphingosine-1-phosphate receptor 1 (S1P1 ) modulators sequester circulating lymphocytes within lymph nodes, thereby preventing potentially pathogenic autoimmune cells from exiting into the blood stream and reaching inflamed tissues. S1P1 receptor modulation may thus offer potential to treat various autoimmune diseases. The first nonselective S1P1-5 receptor modulator FTY720/fingolimod/Gilenya® has successfully demonstrated clinical efficacy in relapsing forms of multiple sclerosis. However, cardiovascular, hepatic, and respiratory side-effects were reported and there is a need for novel S1P1 receptor modulators with better safety profiles...

Critical limb ischemia (CLI), the most severe form of peripheral artery disease, is characterized by pain at rest and non-healing ulcers in the lower extremities. For patients with CLI, where the extent of atherosclerotic artery occlusion is too severe for surgical bypass or percutaneous interventions, limb amputation remains the only treatment option. Thus, cell-based therapy to restore perfusion and promote wound healing in patients with CLI is under intense investigation. Despite promising preclinical studies in animal models, transplantation of bone marrow (BM) derived cell populations in patients with CLI has shown limited benefit preventing limb amputation...

Neural synchrony in the γ-band is considered a fundamental process in cortical computation and communication and it has also been proposed as a crucial correlate of consciousness. However, the latter claim remains inconclusive, mainly due to methodological limitations, such as the spectral constraints of scalp-level electroencephalographic recordings or volume-conduction confounds. Here, we circumvented these caveats by comparing γ-band connectivity between two global states of consciousness via intracranial electroencephalography (iEEG), which provides the most reliable measurements of high-frequency activity in the human brain...

Acute Myeloid Leukaemia (AML) is a rare and heterogeneous haematological malignancy with increasing incidence in the elderly. We performed a population-based, observational analysis of AML cases reported to the Cantonal Cancer Registries in Switzerland. Data was aggregated by the National Institute for Epidemiology and Cancer Registration and stratified for the two time periods 2001-2007 and 2008-2013. Overall, 2351 new AML cases were registered with a stable age-standardised incidence rate (3.0 [95 CI: 2.8-3...

Problems related to the capacity to successfully engage response inhibition are considered a risk factor for the development of substance use disorders (SUDs), but the evidence has been predominantly cross-sectional. In this commentary, we argue that recent longitudinal studies with multi-modal measures of response inhibition can improve understanding of how response inhibition may intersect with substance use among adolescents. Most Stop-Signal studies suggest that slower response inhibition predicts substance use progressions, with one multi-site study showing greater fronto-parietal activity indicative of risk...

PURPOSE: Scapular fractures after reverse shoulder arthroplasty (RSA) are often associated with substantial shoulder impairment. Patient outcomes following either conservative or operative treatment have not been favourable, and consensus is lacking on the best treatment approach. We describe a technique for anatomic reconstruction of fractured lateral and basal acromion in patients at higher risk for diminished function or those for which conservative treatment has already failed. METHODS: Of the 95 patients who underwent RSA at our institution between December 2013 and December 2016, three had post-operative acromion fractures (type II)...

Comparing sea otter recovery in California (CA) and British Columbia (BC) reveals key ecosystem properties that shape top-down effects in seagrass communities. We review potential ecosystem drivers of sea otter foraging in CA and BC seagrass beds, including the role of coastline complexity and environmental stress on sea otter effects. In BC, we find greater species richness across seagrass trophic assemblages. Furthermore, Cancer spp. crabs, an important link in the seagrass trophic cascade observed in CA, are less common...

BACKGROUND: The 6S RNA is a global transcriptional riboregulator, which is exceptionally widespread among most bacterial phyla. While its role is well-characterized in some heterotrophic bacteria, we subjected a cyanobacterial homolog to functional analysis, thereby extending the scope of 6S RNA action to the special challenges of photoautotrophic lifestyles. RESULTS: Physiological characterization of a 6S RNA deletion strain (ΔssaA) demonstrates a delay in the recovery from nitrogen starvation...

Background Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening condition that often leads to severe disability in relatively young and healthy people. This disability is physical in many aSAH survivors, so muscle dysfunction may be an important factor in the functional level of these patients. Thus, measuring muscle thickness represents a suitable method for determining muscle function in patients with acute aSAH, because the disordered consciousness often experienced during the acute phase causes active movement to be difficult for these patients...

Monodisperse, nitrogen-doped hollow carbon spheres of submicron size were synthesized using hexamethoxymethyl melamine as both a carbon and nitrogen source in a short (1 h) microwave-assisted synthesis. After carbonization at 550 °C, porous carbon spheres with a remarkably high nitrogen content of 37.1% were obtained, consisting mainly of highly basic pyridinic moieties. The synthesized hollow spheres exhibited high selectivity for carbon dioxide (CO2) over nitrogen and oxygen gases, with a capture capacity up to 1...
